Farmland soil deep ploughing device

Abstract

The invention relates to a farmland soil deep ploughing device and belongs to the field of an agricultural machine. The farmland soil deep ploughing device is composed of a frame, a suspending frame, front plows and back plows; a hanging frame is installed at the top part of the frame, and the front end of the frame is symmetrically equipped with the front plows through an installing loop; the frame between the front plows is symmetrically equipped with a connector, and the back end of the frame is symmetrically equipped with the back plows through the installing loop. During the working time, the farmland soil can be deeply loosened through the front plows and the back plows, the deep ploughing depth is more than 30cm, thus the bottom layer of the plow can be broken through, the soil thickness is increased, the plough layer structure is improved, and the soil blocking is effectively prevented; the farmland soil deep ploughing device solves the problem that the existing rotary plow cannot meet the moderate deep ploughing requirement, and is featured by simple structure and good practicability; therefore, the farmland soil deep ploughing device is very suitable for the deep loosening work of the farmland soil.

Description

technical field [0001] The invention relates to a deep plowing device for farmland soil, which belongs to the field of agricultural machinery. Background technique [0002] Soil compaction in farmland is one of the important manifestations of soil degradation; the main factors of soil compaction are: too sticky soil texture in farmland, insufficient organic fertilizer and reduced amount of straw returned to the field, long-term single application of chemical fertilizers, farming measures such as suppression and plowing, heavy rain and soil Soil compaction after erosion. At present, the key measure to solve soil compaction is moderate deep plowing of farmland soil. Moderate deep plowing is conducive to protecting the structure of the soil plow layer from being damaged, and is conducive to the growth of crop roots. When the deep plowing depth is greater than 30 cm, it can break the bottom of the plow, thicken the thickness of the soil layer, improve the structure of the plow...

AI Technical Summary

Problems solved by technology

The rotary tiller uses the rotary tiller on the knife-roller assembly to plow and break the farmland soil, and then rakes the farmland soil through the strong pressure plate on the rear end frame of the knife-roller assembly to complete the preparation work before planting the farmland. ; Due to the structural reasons of the existing rotary tiller, its operating depth is 10-15cm; it cannot meet the requirements of moderate deep plowing, so it is necessary to improve it
