Description

The invention relates to agriculture, in particular to machines for cleaning stones. ;

The closest technical solution to the invention is a stone harvesting machine containing a frame on which a loose rotor with arcuate teeth and an additional rotor mounted after the loose tooth — and having a smaller pitch between the teeth — and transporting body 13 are placed.

The disadvantage of this machine is that the transporting body experiences large shock loads resulting from the fact that the organs that feed stones to it discard the latter, and this negatively affects the reliability of the machine.

The purpose of the invention is to increase operational reliability.

This goal is achieved by the fact that the transporting body is made as placed on the frame across the direction of movement of the machine and in front of the loosening rotor of the comb, each of the ends of the rod of which is pivotally mounted on the spike of the crank, while the teeth of the loose rotor are convex in the direction of rotation.

FIG. 1 shows the proposed machine, side view; in fig. 2 - transporting body, front view; in fig. 3 is the same, top view.

The stone harvesting machine consists of a frame 1 with wheel pairs (not shown), on which a loose rotor 2 with teeth 3 of arcuate shape and an additional rotor k with L-shaped teeth 5 are installed, the distance between them in the axial direction is less than between the tooth mi 3 loose rotor 2. In front of the loose rotor 2 on the frame 1 there is a transporting body in the form of a comb having a rod 6

And the teeth 7 fixed on it. Each of the ends of the rod 6 is hingedly placed in the spike 8 of the crank 9. Under the cranks 9, a beam 10 is installed parallel to the rod 6.

Stone harvesting machine works as follows.

When the machine is moving, the rotor 2, rotating against the machine’s travel, removes stones from the soil 3 and rolls them in front of itself towards the teeth of the comb 7. Simultaneously with the movement of the machine, crank 9 is rotated, as a result of which the tooth 7, moving from the rightmost (left) position to the leftmost (right), seizes the stones and rolls them parallel to the axis of the rotor 2 to the roller. At the end of the working stroke, the tooth 7 of the comb abuts against the beam 10, and with further rotation of the crank 9, the rod 6 rotates in the hinges of the shaft 8, raising the tooth 7 upwards. In the next period of rotation, the teeth 7 begin to slide along the beam 10 and, when completed with the full revolution crank, slide down from the beam and assume a vertical position. Further, the described cycle is repeated ..

Thus, the comb moves only those stones that are larger than the distance between the teeth, and smaller stones fall into the area of the additional rotor k.

The implementation of the transporting body in the form of the said comb allows eliminating the removable rotor, spaced. Over the loose rotor, and a receiving conveyor with a reflector mounted behind it, which leads to a reduction in the weight of the machine. And due to the fact that the rotor and comb teeth roll stones on the ground, shock loads on the transporting body, which take place in the known device, are eliminated, which allows to increase the reliability of the machine. a ,,. o fig .. 2 For the time being, shepe; fuck a (afft / stones
