Description
Background of Inven-tion In land clearing operations, it is necessary to bread up any debris into pieces small enough tilat it can be accommodated by equipment subsequently used to till the soil.
The debris to be "pulverized" may include anything from brush to trees. Normally, larger trees are disposed of in other ways, but land clearing operations with which the presen~ invention is intended to cope frequently involve trees, or tree branches, up to as large as four to six inches or so in diameter.
Some prior devices with which I am familiar utilize the ground as an anvil to support the debris for cutting into small pieces by blades on a rotor. This approach works fairly well if the ground is hard, or relatively so, but is completely inef~ective if the ground is soft since, under such conditions, 'the cutting blades merely push the debris, or much of it, downwardly into the soft soil, and fail to break it up.
Another type of device with which I am familiar involves the use of wheel supported, and wheel or power driven, rotary cutters operating against pickup fingers which deliver the debris to the cutters. Devices of this nature operate ~ .
much more effectively than those of the type discussed in the preceding paragraph, but are relativeiy complicated.
~` Prior U~ited States patents with which I am familiar, ' and which disclose devices of the foregoing two types, include:
843,479 'Becerra 1,865,686 'Gilson ~ ~ ~ i,156,234 Jones 2,553,356 Cady ! 1,639,837 ~urner 2,974,472 Gebhart 29 1,786,455 Robbins 3,121,987 ~Earris :: . ~. .. ~ . . . "
The present invention resides in an apparatus for pulverizing debris in land clearing operations, or the like, and includes a frame and a ground engaging rotor extend-ing transversely across the frame and mounted thereon for rotation about a transverse axis of rotation and carrying generally radial, ground engaging teeth arranged in trans-versely spaced, circumferential rows. Debris pickup and breaking means is carried by the frame for feeding debris to the rotor teeth in response to forward movement of the frame, the means cooperating with the rotor teeth to break up the debris. The pickup and breaking means includes pick-up fingers having forward and rearward ends and spaced apart laterally of the frame, and also breaker bars at the rearward ends of and generally perpendicular to the pickup fingers, the rows of rotor teeth passing between the pickup fingers and breaker bars. The pickup and breaker means is pivotally mounted on the frame for movement relative thereto about a transverse pivot axis, the pivot axis being offset rearwardly of the above mentioned axis of rotation, and the pickup and breaking means being pivotable about the axis between an extended, operative position below and rearwardly of the axis of rotation and a retracted, inoperative position rear-wardly of the axis of rotation and above ground level so that '~ the pickup and breaking means moves rearwardly away from the `~ rotor as it pivots upwardly and rearwardly from its extended position to its retracted position to thereby facilitate dumping of any debris caught in the pickup and breaking means.
