Abstract: A beach cleaner for recovering relatively heavy garbage or stones while minimizing the amount of sand entering a garbage recovery unit. The beach cleaner includes a frame formed by a longitudinal member and a lateral member. A towed portion is provided at the front portion of the frame for towing by a tow vehicle. A separator is provided at the lower front portion of the frame to separate and scrape garbage from sandy ground. A recovery unit is provided behind the separator to collect garbage scraped onto the mesh member. At least one separation rod unit is provided having a plurality of longitudinal members and a lateral member for joining the rear ends of the respective longitudinal members. The front end of at least one separation rod unit is secured to the separator so as to be turnable in the up-and-down direction.

Abstract: A box-shaped beach-cleaning trailer is configured to be loaded with, and collectively carry beach-cleaning equipment and a litter collection station. The beach-cleaning equipment are towed by a vehicle to collect litter on the sands. The litter collected by the beach-cleaning equipment is collected in the litter collection station. The trailer includes a pair of rail members disposed on upper edges of the respective opposite side wall portions such that the rail members face each other with an opening therebetween. A sieve unit is detachably mounted on the rail members, and is configured to move a back-and-forth direction along the rail members. The sieve unit is moved in a back-and-forth direction manually; or by using a driving mechanism including a drive wheel, a driven wheel, and a connecting rod arranged between the sieve unit and the driven wheel, for separating colleted litter of various sizes from sand.

Abstract: To provide a waste recovery station for a beach cleaner which is less liable to be bulky after being divided and can facilitate installing work, and which can easily load and unload a beach cleaner and a waste recovery station on and from a trailer. A waste recovery station includes a pair of left and right grounded members, guide members formed like a mountain as viewed from the side and attached to the grounded members, and bar-like connecting members integrally connecting the grounded members. The waste recovery station can recover the waste collected by the beach cleaner towed by the towing vehicle to run on the sand area by allowing the beach cleaner to ride on the waste recovery station. The waste recovery station includes a connecting pipe which removably connect an end of the connecting member to the grounded member.

Abstract: A torque tube with slide out cage system for providing both structural support to the frame of the machine and a protective area for sensitive control systems for the machine. The torque tube with slide out cage system includes a torque tube attached between a first side and a second side of a frame, a side opening within the frame exposing the lumen of the torque tube, and a cage slidably positioned within the torque tube. The cage is capable of supporting various types of control systems such as a valve box, hydraulic systems and electronics.

Abstract: A beach cleaner that is simple in configuration and light in weight and can be manufactured at a low cost. The beach cleaner is easy with regard to maintenance and inspection and can efficiently reclaim various kinds of refuse scattered on a beach. A beach cleaner includes a traveling body with ski members disposed at four corner portions of a frame having a substantially quadrangular shape. The beach cleaner is towed along a surface F of sandy soil by a traction vehicle R. A bar-like scraper is provided at a lower portion of a front portion of the traveling body and extends in a widthwise direction of the traveling body through a scraper supporting member for scraping up refuse on the sandy soil while the traveling body is operating. A refuse reclamation section is provided on the traveling body rearwardly of the bar-like scraper for collecting pieces of refuse scraped up and thrown rearwardly by the bar-like scraper onto a net member.

Abstract: A beach cleaner for recovering waste while moving in a towed state by a traction vehicle. A grating-like portion scoops up waste present in front of the beach cleaner as the beach cleaner is moved and a reticulate portion that is formed behind the grating-like portion to hold waste. As the beach cleaner is moved, waste present in front of the beach cleaner is scooped up onto the grating-like portion and is held with the reticulate portion formed behind the grating-like portion. Sand that is scooped up together with the waste is allowed to drop through the gaps in the grating-like portion.

Abstract: An agricultural tractor comprises a front frame section, a rear frame section carrying the engine and cab and a horizontal beam connecting the front frame section to the rear frame section leaving a space between the front and rear wheels and underneath the beam for receiving the implement in a belly mount position. The rear frame section includes auxiliary wheels which are simple non steering wheels movable vertically and braced against rearward movement which can be lowered by a ram to a position to lift the front wheels away from the ground to a height to move over the implement. The front wheels are steerable by a worm and wheel arrangement to a position at right angles to the normal forward direction to allow manouverability. The tractor can be used for the various operations in growing row crops with the implement attached on a three point hitch rearwardly of the front frame section.

Abstract: A device for picking rocks from a field includes a frame which is mounted on a pair of wheels. A hitch is pivotally attached to the frame and is adapted for engagement with a conventional tractor. The offset of the hitch is adjusted by a hydraulic cylinder to adjust the tracking of the frame behind the tractor. A reel is mounted for rotation on the frame and is powered by a chain and sprocket drive from a rotary hydraulic motor. The reel has a plurality of radially extending spokes, each terminating in a stone picking rake formed by a plurality of spaced teeth. The elevation of the reel with respect to ground level is adjusted by a pair of hydraulic cylinders connected to a pivotal reel mounting frame. A depth stop mechanism is provided to lock the reel in an adjusted elevational position. In a first embodiment, a semi-cylindrical stone collecting box is mounted within the reel frame. As each of the reel spokes rotates to a top position, collected stones fall by gravity into the open stone box.

Abstract: An agricultural machine comprising a motor driven main frame and a detachable harvesting unit. The harvesting unit includes four major parts; a forward digging unit, a screening section, a conveyor system and a receiving bin. The four major parts are specifically located with respect to the main frame.
