Description

[Detailed description of the invention] [Purpose of the invention] Industrial application field The present invention relates to a stone picking device for picking up stones buried or scattered in fields.

BACKGROUND TECHNOLOGY Generally, when stones are mixed or scattered in a field, there are many problems in the growth and cultivation of crops.

Therefore, conventionally, stones in the field have been picked up using specialized stone picking machines.
Conventional rock pick-up machines, for example, use an excavator such as a tip to dig up stones together with soil, transport the stones to a conveyor, shake off the soil while conveying the stones, and carry the stones to the rear. The structure is such that it can be released into the air or stored in the hopper at the rear.

Problems to be solved by the invention According to the structure described above, since the soil is directly excavated by the excavating body, relatively large blocks of stone are often carried to the conveyor, and in such cases, , soil shake-off action becomes uncertain, soil clods may be stored together with stones, and since flat surfaces are excavated and conveyed directly to the conveyor, soil is not carried into the conveyor, that is, the soil is swallowed by the conveyor. There is a problem with uncertainty.

The present invention was developed with these points in mind, and it involves softening the cultivated soil so that it is easier to shake it off before picking up stones, and
The object of the present invention is to provide a stone picking device which is made with ridges so that soil containing stones can be easily swallowed, thereby making it possible to surely pick up stones.

Means for solving the structural problems of the invention The rock picking device of the invention has a structure installed at the front of the tractor 1.
A tilling work body 3 is attached to the rear of the tractor 1, which has a large number of tilling claws 10 radially projecting inward in the axial direction of the tillage shaft 11 to expand and soften the tilled soil as well as to ridge it. A stone picking mechanism 4 is installed, which is equipped with a tip 23 for digging up the soil that has been expanded and ridged by the tip 3, and a conveyor 24 that shakes out the soil from the soil brought in from the tip 23 and picks up stones. be.

Function According to the stone picking device of the present invention, when the tractor 1 travels and the rotary work body of the tilling work body 3 and the conveyor 24 of the stone picking mechanism 4 are rotated,
Each tilling claw 10 of the tilling work body 3 is rotated in the upcut direction, and the conveyor 24 of the stone picking mechanism 4 is rotated clockwise.

The tilling claws 10 of the rotary work body first till and crush the tilled soil to swell and swell the soil, and since each tilling claw 10 is attached facing inward, the swollen soil is automatically mounded into furrows. Then, this expanded soil in the furrow a is dug up by the tip metal 23 of the rock picking mechanism 4 at the rear, and the soil mixed with stones is conveyed to the conveyor 24. During conveyance, the stones are shaken off the conveyor 24 and are conveyed rearward and upward.
