  • Patent number: 4364434
    Abstract: A bucket mounted ground-raking and rock-gathering attachment is picked up off the ground following rock-gathering, by operation of hydraulic cylinders on the tractor provided for lifting and lowering the bucket. The tractor is then driven to a dumping site whereat a passive tension strap, interconnected between a top portion of the attachment and an upper portion of the bucket support frame, holds the attachment in a substantially level position. Then, hydraulic cylinders on the tractor are operated to rotate the bucket, for dumping the debris, while the attachment is substantially maintained in position. A passive tension strap, interconnected between the top of the bucket and the top of the attachment to limit the extent of downward pivotal movement of the attachment relative to the bucket, bends to permit such dumping rotation of the bucket.

  • Patent number: 4345655
    Abstract: A rock picker has a plurality of high capacity conveyors, one of which is used for storing rocks during the picking operation. The conveyors quickly unload the stored rocks into a truck or at some other desired location. The storage conveyor is arranged so that it does not take up any substantial amount of space greater than the rock picker frame, but yet is sufficiently large in capacity so that it can store a large number of rocks as they are picked. Loading conveyors are sequentially placed so that first and second normally continuously operating conveyors load into the third storage conveyor in sequence. A storage hopper is provided at the input end of the storage conveyor, and the conveyor is intermittently operated to carry the rocks from the hopper in a layer along the length of the storage conveyor. When the storage conveyor is loaded with rocks, the storage conveyor is run to discharge the rocks off one end.

  • Patent number: 4319641
    Abstract: A rock picker of the floating rotating reel type has the following features: (1) An intermediate pinion is provided for the drive of the reel at the pivot point for the reel assembly. This enables the reel to pivot to clear obstacles without per se changing the relative driving relationships; center-to-center distances can remain constant regardless of the pivoting of the reel. (2) Loosely attached grille teeth permit rocks to wiggle out from between grille teeth. Each grille tooth is provided with a receptacle and shoulder which bears against an angle-iron transversely located on the frame. Clearance between the receptacle and the angle iron permits wiggling of the teeth to occur. A bolt passing through a spacer flange attached to each tooth prevents the tooth from sliding off the angle iron.

  • Patent number: 4313502
    Abstract: The present invention relates to a rock extractor apparatus and method of using the rock extractor for removing rocks embedded in the ground and/or for removing rocks partially embedded in the ground. The invention is particularly directed to removing rocks from soil suitable for farming. The rock extractor consists essentially of a digger unit, a grate unit and a conveyor unit, all of which cooperate to efficiently and effectively extract rocks from the soil and to render the soil suitable for cultivation. The rock extractor is attached to a draft machine such as a tractor and pulled through the soil.The tractor pulling the extractor through the soil causes rock and soil to be dug up and moved over the digger unit. The grate unit and conveyor unit cooperate to forcefully drive the conveyor unit downwardly and forwardly into the pile of rock and soil that is moved from the digger unit onto the grate unit and to rapidly move the rock and soil rearwardly along the grate unit.

  • Patent number: 4282932
    Abstract: This rock picker invention is a towable farm implement which is capable of removing rocks from a farm field. A plurality of buckets scoop up quantities of soil as the rock picker is towed by a tractor. The buckets are mounted on a pair of cables which pass over guide wheels. The cables are forced to move by a power source so that the buckets are forced into, across and out of the ground. The guide wheels are mounted on axles on a conveyor frame which allows the buckets and cables to be lifted to a transport position and which allows the angle of attack between the buckets and the ground surface to be varied. The buckets are equipped with openings and shaped such that soil falls from the buckets when the buckets are lifted. The cables are guided such that the buckets are caused to invert and dump the rocks collected into a hopper. The hopper is equipped with a lifting linkage to allow transfer and disposal of rocks collected.
