  • Patent number: 10132055
    Abstract: A front-mounted clamshell scoop or shovel arrangement mounts onto the snowplow mounting bracket of the frame of a snowplow assembly when the blade has been removed. The scoop can be closed and lowered to scoop and pick up work-site debris or other materials, raised so the materials can be transported to a collection site, and the jaw portion is rocked to an open position to allow the material to drop from the clamshell scoop. In controls for the snowplow assembly serve to raise and lower the scoop and to open and close it.

Another common instrument attached to a machine for collecting and transporting materials is a bucket. The present disclosure describes a bucket that engages the tines of a fork, and therefore can be used with a machine that already has a fork attached. The present disclosure also engages with tines of multiple lengths, meaning that the same bucket will engage with forks from different machines.

  • Patent number: 8966791
    Abstract: A staggered edge bucket excavation tool has a body formed by side-leading edge plates, a back sheet, and a plate with a front leading edge spanning a region of the bucket between edge plates. The tool defines a volume for receiving material excavated from a hard packed substrate. Two or more teeth may be mounted along the front leading edge, with each tooth defining a forward surface non-aligned with forward surfaces of all other teeth, thereby disposed for individual, sequential initial engagement with the substrate during excavation. The teeth define a flat plane generally parallel to the planar plate. Each tooth defines an excavation angle between a surface of the tooth and the axis of rotation, and the excavation angle of each tooth being different from excavation angles of all other teeth. In implements, the front leading edge defines multiple edge portions or defines a single multiple edge portion.

A bucket is rotatably attached to the frame, and a blade is attached to the frame and positioned within the bucket so as to substantially span the height and width of the bucket interior. In a first position, the bottom wall of the bucket is positioned substantially horizontally. The tractor moves so as to insert the open mouth of the bucket into a quantity of loose material, then raises the bucket and moves to a desired location. The bucket is lowered so that drag members on the bucket contact the ground; forward movement of the tractor causes the bucket to rotate, creating an opening between the bucket and the blade and causing the loose material to flow out of the bucket onto the ground.

  • Publication number: 20140230292
    Abstract: A staggered edge bucket excavation tool has a body formed by side-leading edge plates, a back sheet, and a plate with a front leading edge spanning a region of the bucket between edge plates. The tool defines a volume for receiving material excavated from a hard packed substrate. Two or more teeth may be mounted along the front leading edge, with each tooth defining a forward surface non-aligned with forward surfaces of all other teeth, thereby disposed for individual, sequential initial engagement with the substrate during excavation. The teeth define a flat plane generally parallel to the planar plate. Each tooth defines an excavation angle between a surface of the tooth and the axis of rotation, and the excavation angle of each tooth being different from excavation angles of all other teeth. In implements, the front leading edge defines multiple edge portions or defines a single multiple edge portion.

  • Publication number: 20140173947
    Abstract: Machines are often used to collect and transport materials in a work environment. One of the more common methods of collecting and transporting materials is with a fork having tines. Another common instrument attached to a machine for collecting and transporting materials is a bucket. The present disclosure describes a bucket that engages the tines of a fork, and therefore can be used with a machine that already has a fork attached. The present disclosure also engages with tines of multiple lengths, meaning that the same bucket will engage with forks from different machines. The bucket has first and second side members; a collecting member extending between the first and second side members; and an engagement portion having an engagement surface and a pocket.

  • Patent number: 8695240
    Abstract: A machine bucket assembly includes a bucket having a top section, a bottom section, and a curved middle section. The bucket assembly may also include a kinematic reaction point about which the bucket is configured to rotate. A loadability index of the bucket may be between approximately 0.95 and 1.05. The loadability index is a ratio of a distance between the kinematic reaction point and a tip of the bottom section and a distance between the kinematic reaction point and a tip of the top section.

  • Patent number: 8631596
    Abstract: An improved material handling bucket assembly is configured for construction or agricultural front loading or backhoe applications. Scraper and grader blades pivotally mounted relative to the bucket bottom cooperatively move to provide normal bucket operation, or scraping, or grading operations. A scraper blade selectively rotates between a first position closing an opening through the bottom wall of the bucket to a second position extending below the bucket for removing ground soil during a scraping operation and directing the removed soil into a collection chamber of the bucket. A single power source and linkage assembly controls movement of the scraper and grader blades, which also cooperatively move to change the size of the opening in the bottom wall during a scraping operation.

  • Publication number: 20130318839
    Abstract: A connection for firmly securing an adapter for carrying a digging tooth to a lip of an excavating container. The connection has substantially aligned openings in the adapter and the lip. A pressure applying unit, such as a hydraulic actuator, is arranged inside the opening and generates a generally horizontally acting force which draws the adapter and the lip towards each other. A stress member is operatively coupled to the hydraulic actuator and resiliently deforms relative to its relaxed shape when it is subjected to the horizontally acting force. The wedge is shaped so that upon a reduction or cessation of the horizontally acting force the stress member, remains in the resiliently deformed state in which it draws the adapter and the lip towards each other and keeps them immovably secured to each other until the wedge can be withdrawn following a repressurization of the hydraulic actuator.
