A device for removing stones from farmland

Abstract

The invention discloses a device for removing stones in farmland, which relates to the field of land preparation agricultural machinery in agriculture or forestry. Screening box, the frame is equipped with a staggered sorting mechanism that transports the mixture of stones from the shovel to the rough screening box; the staggered sorting mechanism includes arc-shaped claws that are rotatably connected to the feeding place on the side of the shovel 1. The power part that is installed on one side of the frame and rotates, and converts the rotating power of the power part into the linkage part that rotates the arc-shaped claw; above the frame, there is a removal device for screening the mixture of stones that enters the coarse screening box. Stone device; the stone removal device includes a separation mechanism that makes the coarse screening box shake intermittently and a soil removal mechanism that provides a vibration source through the falling and bouncing vibration of the stones on the lower side of the coarse screening box. The technical effect is to return the soil to the ground, avoiding The loss of soil does not damage the land structure.

Description

technical field [0001] The invention relates to the field of agricultural machinery for soil preparation in agriculture or forestry, in particular to a device for removing stones from farmland. Background technique [0002] The farmland often contains a lot of stones, the soil structure is damaged, the soil nutrients are missing, and the water storage capacity is deteriorated, which will not only affect the growth of crops, but also affect the mechanized operation, causing the tillage tools to be damaged by contact with hard stones. In order to facilitate mechanical farming and soil improvement, the method of artificial stone picking is usually used to clean up the field stones. This method is not only labor-intensive and inefficient, but also incomplete in picking up stones. In the stone, seriously affect the agricultural development. [0003] The existing farmland stone removal machine shovels the stones and soil together, puts them into the collection box, and transports...

AI Technical Summary

Problems solved by technology

[0002]There are often a lot of stones in the farmland, the soil structure is destroyed, the nutrients of the soil are lacking, and the water storage capacity becomes poor, which will not only affect the growth of crops but also affect the mechanized operation It will cause damage to the farming implements in contact with hard stones. In order to facilitate mechanical farming and improve the soil, the method of manually picking up stones is usually used to clean up the field stones. This method is not only labor-intensive and inefficient, but also not thorough in picking up stones. , the stones in the lower layer of the soil are difficult to find, and the stones in the farmland soil cannot be fundamentally removed, which seriously affects the development of agriculture

[0003] The existing farmland stone removal machine scoops up stones and soil together, puts them into a collection box, and transports them to one place for screening. Although the stones in the farmland are removed, the original soil in the farmland cannot be discharged in real time, which changes the original soil of the farmland. land, destroying the land structure of the farmland, reducing the thickness of the land, and making the land barren
