Vehicle-Attached Excavation Implement

Abstract

A vehicle-attached, task-associated excavation implement with interchangeable rotational excavation apparatuses is conceptualized in this application. The implement is similar to McGee's Tractor-Mounted Excavation Implement, but is conceptualized in a new way of combing parts or portions of the implement with vehicles currently existing in the prior art, without the need for a tractor equipped with power-take-off. This vehicle-attached implement can be supported by a variety of motorized vehicles, utilizing a variety of apparatus-powering options. An assortment of steering options could be used, and movements of the apparatuses, either with or separate from the implement, provide diverse functionality. Tasks supported by the rotational excavating apparatuses include Foundation footings, trenches, rounded ditches, shallow V-shaped ditches, landscape or garden beds, and shallow graded depressions for sidewalks or simple slabs. Excavating apparatuses have claws or cutting elements attached to surface at angles to propel soil directionally.

BACKGROUND

This proposed embodiment relates to excavation or earth loosening and moving equipment, including backhoes, trenchers, ditchers, and rotary equipment used in excavation. The proposed vehicle-attached excavation implement will be useful in small-scale construction, hobby farming or gardening, landscaping, irrigation, utilities and pipe laying, roadside or city development and maintenance in some areas, land-owner maintenance, and possibly firefighting with rapid excavation needs in some less dense forests. This application delineates a new combination use of the previously patented Tractor Mounted Excavation Implement, awarded to the present applicant in 2015, wherein the implement and apparatuses are attached to, powered and maneuvered by, a vehicle, rather than pulled behind a tractor as in the previously patented embodiment.

Discussion of the Prior Art

This application is primarily relevant as relates to the present inventor's previous patent for a Tractor-Mounted Excavation Implement, awarded Nov. 24, 2015 to Bruce Wade McGee, and assigned U.S. Pat. No. 9,194,103 B2. The patent has been assigned to McGee Innovation, LLC. A re-issue application has since been submitted to broaden several of the claims in the awarded patent, assigned Ser. No. 14/999,506, and dated May 17, 2016.

McGee's Tractor Mounted Excavation Implement is power-take-off driven and attaches to a tractor's 3-point-hitch, with multiple interchangeable rotational excavation apparatuses, described as task-associated. The implement is presented with three interchangeable apparatuses addressing four tasks, including apparatuses for foundation footers/trenches, rounded ditches, or shallow V-shaped ditches. Later improvements have been conceptualized and patents are pending, including the addition of two apparatuses, one for creating landscape or garden beds and one for shallow graded excavations for sidewalks or slabs. Additionally, several other enhancements have been conceptualized, including the addition of adjustable and extendable tines or cutting elements to increase range of usefulness, and additions to the axle of certain apparatuses to improve the movement of excavated soil onto the banks of the excavated depression.

McGee's implement has the potential to revolutionize small-scale excavation. The unique value of McGee's implement is it's propensity toward usefulness in multiple small-scale applications, but where speed and precise excavations are important requirements. Even so, the implement's main drawback is that it must be pulled behind a tractor, with somewhat difficult transportation and maneuvering. It is also limited to power-take-off attachment for rotational power.

Concrete filled foundation footings are constructed around the perimeter of a building for structural support, and are typically dug by backhoes or track hoes. These machines are hefty and require heavy, large trucks and trailers for transport; transport itself can be dangerous and expensive. Backhoes and track hoes have awkward, slow, and erratic motions. Their resulting evacuated areas are not precise with clean sides, and often require significant backfill. Backhoes and track hoes are capable of deep, large excavations, and are appropriate in some instances and certain geographical locations. However, in the Deep South of the US, and in many other locations worldwide, small-scale excavation of shallower footings with lighter-weight equipment is appropriate.

Trenches for the laying of pipe and other applications are typically dug with revolving chain cutters. Their width of cut is not easily adjustable. They require extensive and expensive maintenance. Small scale applications often use a portable trencher, and even though these are smaller and lighter, they require separate transport to the site.

Small ditches for drainage are typically dug and shaped with hand tools or tractor-mounted ditchers. The shape and cutting depth of these implements are limited and they are dependent on large equipment.

Grades for sidewalks, slabs, or flat surfaces are typically shaped by a boxblade attached to a tractor or by large grading equipment. These boxblade implements cannot easily excavate or penetrate into undisturbed ground, sod, roots or similar obstacles. Small-scale applications are often accomplished by hand with simple tools, perhaps with the assistance of a tiller or sod remover.

Bedding for landscapes or gardening are typically shaped by hand tools, or by using agricultural equipment geared toward large farming outfits. Agricultural implements are most often dependent on tractors, and require significant room for storage when not in use.

Each of the aforementioned excavation tasks are addressed by equipment found in the prior art. Excavators, chain-type trenchers, ditchers of various shapes and sizes, box blades, scrapers, and landscape bed or farm row creators are readily available in commercial use. Many of these are attached to heavy equipment and are geared toward large construction operations. However, no one machine is found that can perform all, or a combination of, these tasks on a small scale, with speed, flexibility and preciseness, while dispersing soil evenly on banks of excavated area.

Bruce Wade McGee's Tractor Mounted Excavation Implement solves many of these issues. However, the implement, in its initial embodiment, is limited to being pulled behind, and powered by, a tractor. It is not suited to function with multiple vehicles, or to using various methods of powering the implement's apparatuses. It does not easily extend or adjust depth to accommodate excavation needs. Later patent application for enhancements have included many of these upgrades. However, the implement still is dependent on tractors, which are not as maneuverable as modern day skid steer vehicles, zero-turn vehicles, or tracked vehicles. Many tractors are not equipped with hydraulic support for implement functioning. The three-point-hitch of tractors is typically in the rear, leaving it difficult for the operator to see the apparatuses and follow lines on the ground. These challenges with use of the tractor-mounted version of the implement are addressed in the current application.

BRIEF SUMMARY OF THE INVENTION

The objective of this application is to present a conceptualization of McGee's implement, along with its interchangeable apparatuses for excavation tasks, in a new combination, attached to any of a variety of vehicles for propelling the implement. This application pairs the implement with alternative vehicles currently found in the prior art and in commercial applications, and provides for alternative powering sources and maneuvering mechanisms for the implement.

A first embodiment is a vehicle-attached excavation implement, with interchangeable task-associated rotational excavation apparatuses. Excavation tasks that can be accomplished include foundations, trenches, rounded ditches and shallow V-shaped ditches, excavation of landscape or garden beds, and shallow graded areas for sidewalks or simple slabs. Excavated spoils are deposited on the banks of the newly excavated depression. The implement will be attached to or within a vehicle for movement along the ground, using a frame, booms or arms. The apparatuses are mounted to the implement on an axle or hub appropriate for the task and the selected apparatus. The apparatuses are rotatable, around an axle or hub axis that is horizontal to the ground.

Any number of vehicle types could be used for attachment of the implement. The vehicle itself is not considered an element of this invention, but rather is an exploited mechanism to utilize the attached implement. Many vehicles are present in the prior art that would suffice as a delivery mechanism for the implement. For example, the vehicle-attached implement can be propelled using wheels or continuous tracks. The implement can be guided or maneuvered by skid steer, zero-turn steering, remote control, computer-assisted steering, conventional steering, or hand-guided steering wherein the operator walks behind or beside the unit, or the operator sits or stands on a platform.

Power is diverted from the vehicle to the apparatuses, and may employ a variety of sources, depending on the type, size and features of the vehicle utilized. Hydraulic power will be an option on many of the potential vehicles. Alternatively, an independent power source may be utilized.

The vehicle-attached implement, supported within or near the motorized vehicle by one or more arms or booms, or a frame, has multiple movable apparatuses. Movement can be accomplished by moving the implement's frame, booms or arms, or by moving the axle of the selected apparatus independently. The arms or booms can extend away from or contract back toward the vehicle. The implement's apparatuses are able to pivot, tilt, and raise and lower vertically. These movements are meant to accommodate inclines in ground or in the excavation task, but also the depth of the excavation. Footings that step-down in increments, such as for masonry installation, can be guided by computer or other means. Depth of excavation can additionally be assisted by laser, which beams to a marked depth indicator on the implement.

Operators and nearby bystanders are protected from excavated debris by guards strategically located. The guards' location, material, and use will be guided by the type and size of the vehicle chosen for attachment of the implement.

The axle of certain apparatuses are equipped with ‘fins’ or continuous blades, attached to exposed sections of the axle. The fins or blades can be welded in place in some instances, and secured in place prior to the task in other instances. Fins are principally perpendicular to body of the apparatuses, but angle laterally or extend spirally around exposed axle to move excavated soil to outer banks of the resulting excavated depression.

A second embodiment includes a plurality of rotational excavation apparatuses, each shaped and designed for a different excavation task. The apparatuses are each equipped with claws or cutting elements attached to the face of the apparatus, at lateral angles to propel soil outward, or medial angles to propel soil toward center. There are additionally a set of tines attached vertically, extending past depth of claws, to break up soil for ease in excavation. A second set of tines is attached horizontally to extend width of excavation area on certain apparatuses. These tines are adjustable and may be expanded and locked or bolted in place based on the need for excavation task.

Advantages of the proposed embodiments in this application include those seen in the McGee Tractor Mounted Excavation Implement, such as its practicality and straightforward operation, and its safety, economy and convenience compared to larger, bulkier equipment. Its most unique features include its speed, effectiveness and flexibility. Its excavated depressions are ‘cleaner’ and more precise than those of larger, clumsier equipment, and are created in significantly less time. Lastly, but most importantly, its multiple interchangeable apparatuses provide solutions to numerous excavation tasks.

In the proposed embodiments herein, added advantages include improved versatility, with potential attachment to any number of vehicles, and various powering sources and maneuvering options. The need for a tractor with power-take-off capability is eliminated, and hydraulic control is one more effective option for powering implement apparatuses. Transporting various machines to the job site is replaced by one vehicle-attached implement with multiple apparatuses. Enhancements in accommodating excavation needs include methods to adjust and extend depth of cut and width or area excavated. In most vehicle-attached circumstances, the operator will have improved line of vision of the implement and apparatus operation.

Compared to larger, bulkier equipment such as backhoes, speed and precision in digging foundation footings is enhanced. Compared to chain-type trenchers, adjustable width of excavation and less extensive maintenance are key features. Compared to large ditchers, bedding equipment and boxblades, the need for transporting, storing and maintaining heavy equipment is reduced. Tillers and sod removers perform a portion of the work for creating sidewalks and slabs, but do not fulfill the whole task. Having the versatility of the McGee implement extended to applications other than tractor-pulled with power-take-off rotational power will provide solutions previously unrealized.

DETAILED DESCRIPTION OF INVENTION

This embodiment combines vehicles from the prior art with an implement and apparatuses set forth in the previously patented Tractor Mounted Excavation Implement, and later Enhancements and Extensions to the implement. While the vehicles themselves are not claimed herein, multiple combinations are presented to show how the implement could exploit various delivery platforms. Additionally, various mechanisms providing rotational power to the apparatuses are shown, as are numerous methods of directing and maneuvering the apparatus for increased versatility.

Rather than a tractor-mounted implement, presented herein is a vehicle-attached excavating implement for multiple excavating tasks, referred to as the task-associated excavations of depressions in the earth. These interchangeable task-associated rotational excavating apparatuses can address numerous tasks including, but not limited to, forming foundation footings, ditches, trenches, landscape or gardening beds, or shallow graded excavations for sidewalks or simple slabs. Using the rotational excavating apparatuses allows excavated spoils to be easily deposited on banks of a newly formed depressions.

FIGS. 1 through 8 illustrate the various apparatuses as they might be viewed when attached to a vehicle. In the previously embodied implement, all apparatuses were interchangeable within a heavy perimetrical frame that was dragged behind a tractor, with the power-take-off unit of the tractor supplying rotational power to the apparatuses. This embodiment suggests an implement that can vary in shape and form depending on the vehicle for which it is manufactured to attach. A frame, booms or arms attached to or within a motorized vehicle will support the apparatuses, which are mounted on a rotatable axle or hub horizontal to the earth. FIGS. 9 and 10 show specific elements of the embodiment in more detail.

Regardless of the vehicle selected, the implement will provide a means of harvesting and directing soil. Most apparatuses direct soil up, outside, and laterally away from the excavated depression, while one is designed to direct soil medially, toward the center area of two excavated depressions. A task-associated rotational excavating apparatus is chosen for a designated task. Each apparatus is formed in a practical width and shape for its designated excavation task. The vehicle selected will determine the most effective rotational power system for the apparatus, either relating power from the motorized vehicle or providing an independent source to operate selected rotational excavating apparatus.

FIGS. 11 through 17 pair various apparatuses with several vehicles that could serve to mobilize and power the implement. While the vehicles themselves are not claimed herein, it is necessary to illustrate the versatility of the implement when considering its attachment to a vehicle. Selecting a vehicle for propulsion the implement along the ground along the ground may consider several options. Vehicles utilizing wheels or continuous tracks, either of steel or re-enforced rubber, could be selected as a means of reducing traction and slippage while improving stability and steadiness in propulsion of the implement. Several types of vehicles, including those with conventional steering, skid steer or zero-turn steering, remote or computer-assisted steering, or hand-guided steering such as walking, behind or beside, standing or sitting on platform, can be considered to navigate or maneuver the implement along the ground. Such steering mechanisms can either integrated into the vehicle or independent from the vehicle. A powering mechanism for the task-associated rotational excavating apparatuses must either integrated into the vehicle or an independent source must be implemented. Options include hydraulics, power-take-off connection, or direct electro-mechanical connection. There is a slight risk of airborne soil and debris when the apparatuses are in use, so any vehicle attachment must consider how the operator will be protected. The type of protection will vary with the type of vehicle chosen and the manner in which the implement attaches.

As shown in FIG. 1, the ‘trencher’ apparatus, indicated by numeral 101, is cylindrical and relatively narrow compared to ‘footer’ apparatus, not shown in FIG. 1, with lateral sections of footer apparatus removed for a narrower apparatus. Trencher 101 attaches to or within the vehicle via a frame, or one or more arms or booms.
