  • Patent number: 10039233
    Abstract: This pick-up apparatus for picking up harvested root crop defines a pick-up plane and comprises a pick-up section. The pick-up section comprises a pick-up member adapted to pick up the root crop, and a cleaning member. The pick-up member defines a pick-up position with respect to the pick-up plane. The pick-up apparatus comprises a cleaning adjustment device adapted to adjust the position of the cleaning member between at least two cleaning positions, the cleaning positions being different one from another. In each of the cleaning positions of the cleaning member and while the pick-up member is in the pick-up position, the distance of the cleaning member with respect to the pick-up plane is different from the distance of the cleaning member with respect to the pick-up plane in the other cleaning position.

  • Patent number: 9352359
    Abstract: Disclosed is a dirt sifting device for placement over a wheelbarrow, comprising a frame and a filter screen disposed over the frame. In an embodiment of the present invention, the dirt sifting device comprises a first frame connected by a hinge to a second frame. The hinge allows the first frame to rotate relative to the second frame and is adapted to maintain the frames at any of a variety of angles. A filter screen is disposed over each of the first and second frames. The frames define the perimeter of the filter screens. The frames may be rotated towards one another such that the frames overlap in a closed configuration convenient for storage. Alternatively, the frames may be rotated away from one another and the device can then be placed over a wheelbarrow for dirt sifting. Overall, the device serves as a means for separating dirt from unwanted materials.

    Abstract: The loader bucket sieve apparatus is clamped between the jaws of the bucket of a bucket loader or the like, without tools or fasteners. Importantly, as the apparatus rests upon a given surface, the loader operator need only place the jaws of the bucket in the appropriate positions and then clamp the jaws together, reversing said procedure when wishing to disengage the apparatus. The apparatus may have straight supports or concave supports, depending upon need and bucket application. The sieves may extend beyond each side of the supports at each side of the apparatus in order to increase work surface beyond the bounds of the jaws. The sieves may be equidistantly spaced and may also be unequally spaced apart. Sieves may be disposed within all the holes or part of the holes of the supports.

  • Patent number: 6783007
    Abstract: A device enabling the timely removal and subsequent recycling of residues remaining in a pouring chute through which the load of a cement from a mixing drum of a mobile delivery vehicle was discharged. A strainer on a movable arm attached to the vehicle is placed under the chute to receive an effluent which results from spraying the inside of the nozzle with water. Solid particulates are retained by the strainer and a slurry which emerges from the strainer is pumped into the mixing drum, allowing the separated materials to be recycled when the vehicle returns to its base.

  • Patent number: 6763949
    Abstract: A waste recovery station for a beach cleaner for recovering waste raked up by a beach cleaner. A waste recovery station for a beach cleaner includes a pair of station members arranged in parallel with each other through a required spacing. Each station member is provided with a pair of support posts with a foot such as, for example, a circular or square flat plate fixed to a lower end of each support post and is also provided with a guide member fixed to upper ends of the support posts. In the guide member, a longitudinally intermediate portion is formed as a horizontal portion and front and rear end sides are formed as slant portions and are bent downwardly at an obtuse angle. The beach cleaner A is lifted by the guide members while passing between the station members, whereby waste caught on rakes is allowed to drop onto the sand.

  • Patent number: 6722505
    Abstract: Aggregate mixtures such as dirt, sand, rock, concrete, etc. are separated into piles according to size by continuous agitation of the mixture and by gravitational and centrifugal forces exerted thereon. A container for the material, such as the bucket of a backhoe, has the bottom thereof at least partially open. An adjustable, hydraulically-driven rotating disk attaches to and covers the open portion of the bottom of the container, the combination having a gap, or a selected spaced-apart relationship, between the stationary container and the rotating disk. The mixture is agitated by the rotating disk and by contact with the other particles in the container. Particles smaller than the selected gap distance are thrown out through the gap between the disk and the open portion of the container by centrifugal force. Material larger than the selected gap size remains in the container.

  • Patent number: 6712218
    Abstract: A soil screening device includes a screen frame having a screening surface, and a supporting frame. The supporting frame may have rearwardly disposed rigid uprights supporting the screen frame. The screen frame is pivotally mounted to a first upper member mounted at an upper end of the uprights, for pivoting between a lowered position and an elevated position. The supporting frame has a base frame extending forwardly of the uprights. Upper members of the base frame have at least one wedge selectively positionably mounted thereon, for example atop the upper member of the base frame. The wedge or wedges are positionable to engage a lower edge of the screen frame when in the lowered position bearing down on an upper inclined surface of the wedge or wedges. The wedge or wedges are selectively positionable relative to the upper members of the base frame so as to selectively adjust an angular orientation of the screen frame relative to the uprights.

  • Patent number: 6698594
    Abstract: A mobile screening machine with a frame on tracks, having a hopper and a main conveyor mounted to a frame. The main conveyor conveys particulate matter from the hopper to a screening device positioned beneath the upper end of the main conveyor. The particulate is screened into three grades of coarseness, with the coarsest falling into a chute, the middle coarseness falling onto one lateral conveyor and the finest falling onto an underscreen conveyor, which preferably is driven downhill onto another lateral conveyor. The tracks permit the machine to be driven around the work site and onto and off of a trailer, and the entire machine can be remotely controlled. The downhill conveyor permits loading of the hopper from both sides of the frame.

  • Publication number: 20020195378
    Abstract: A vibration-reducing eccentric weight system mounted to the driveshaft of a screen box in a portable screening plant with the eccentric weight system's center of gravity on the driveshaft's axis of rotation. The eccentric weight system includes a weight that is radially slidably mounted to the driveshaft, but biased so that its center of gravity is spaced from the driveshaft's axis of rotation during slow and no rotation. Upon rotation above a preselected speed, the centrifugal force displaces the weight radially outwardly. This causes a gradually increasing vibration corresponding to gradually increasing distance between the weight's center of gravity and the driveshaft's axis of rotation.
