Abstract: A garbage separation and recovery machine for beach cleaning that has mobility and can perform a garbage separation and recovery work according to the situation is provided. The garbage separation and recovery machine has a drum type sieve body (54) that is freely rotatably secured to a vehicle body frame (51) towed by a vehicle, a driving gear (92) that is freely rotatably supported by the vehicle body frame (51) and secured to an axle (52) to which right and left wheels are secured, and a mechanism portion (91) for transmitting the driving force of the driving gear (92) to the drum type sieve body (54). The mechanism portion (91) has a gear switching mechanism (95) for performing a switching operation between an automatic rotation mode in which the drum type sieve body (54) is rotated by the rotational force of the wheels (53) and a manual rotation mode in which the drum type sieve body (54) is released from the rotational force of the wheel (53) and allowed to be manually freely rotatable.

Abstract: A direct harvester includes a cutting portion, a lifting portion and a feeding portion. The cutting portion typically includes a cutter rod for severing plant roots and a kicker rod for encouraging the plant to the soil surface. The lifting portion typically includes a rotating pickup head for lifting the plants off the soil and separating the plant from the soil, and a pair of rotating tubes to move the plants and encourage further separation of soil from the plants. The feeding portion includes an auger which receives the plants from the rotating tubes and channels the plants into the opening of a combine feeder housing. Preferably, the floor below the auger is screened to allow soil which is knocked free by the auger to fall back to the ground. Additionally the lifting portion and the feeding portion are preferably pivotably attached to one another to enable the harvester to adapt to differing contours in the soil.

Abstract: An agricultural implement which may be pulled by a tractor in an agricultural field for improving soil conditions, provided with the capability to sort rocks according to their sizes whereby rocks of only desired dimension range are crushed, this implement consisting of a frame carried by two wheels, a drawbar assembly for attaching the frame to a tractor, a rock-transporting tilted belt conveyor assembly provided with a ploughshares means, a pair of corrugated crush rollers, a bin for collecting stones of large dimensions, and a hydraulic power system driven by a drive shaft connected to the power take-off of a tractor.

Abstract: An implement for gathering objectionable rocks and debris from the ground including a positive stop for limiting the range of displacement of the gathering mechanism relative to the ground. In the embodiment described, the gathering mechanism comprises a first roller to engage the ground to dislocate rocks and debris therefrom; and a second roller forming a gap above the first roller through which only selected rocks and debris may pass. The height of the first and second rollers in reference to the ground is vertically adjustable. The first and second roller are displaced upward by large forces placed upon the first roller.

Abstract: A harvester is provided for mechanized harvesting of vine crops such as cucumbers. A harvester head is provided with a plurality of rollers, each of which comprises a cage structure rotatable about a central longitudinal axis, a rotatable shaft within the cage structure and extending generally parallel to but offset from the longitudinal axis of the cage structure, and a plurality of fingers mounted to the shaft and extending radially outward through the cage structure. Because the shaft and the cage structure rotate about offset axes, the extension of the fingers beyond the cage structure varies along the rotational arc of the roller. The rollers are preferably mounted to provide maximum extension of the fingers during lifting of the vine mat and crop. Belts on the forward roller are spaced apart to permit dispersion of soil picked up with the vine mat.

Abstract: A wheel mounted pull type chassis includes a side hitch bar for securement to a tractor or the like. A reel assembly is journalled for rotation and is situated transversely at the front of the chassis and picks up rocks, stones, dirt, etc. and deposits same on an upwardly and rearwardly inclining slotted apron with the teeth of the pick up bars at the reel passing through the apron teeth and depositing the picked up material into a screening wheel journalled for rotation about a generally horizontal but inclined longitudinal axis so that the wheel is tipped rearwardly from the vertical. The periphery of the wheel is slotted. It is supported upon a pair of spaced apart support wheels one wheel of which is driven and which engage a track around the outer periphery of the wheel. Three equidistantly spaced rear support wheels engage the rear of the periphery of the wheel for added support.
