A general-purpose automatic detection and control device for tillage depth

Abstract

The invention belongs to the technical field of agricultural machinery, and relates to a universal type automatic tilling depth detection control device. The device comprises multiple automatic tilling depth detection control monomers and a PLC control system; each automatic tilling depth detection control monomer comprises a support table, a machine and tool mounting frame, a tilling depth adjusting unit, a laser displacement measurement sensor and a laser ranging sensor, wherein the laser ranging sensor measures the distance between the support table and the operation surface, the tilling depth adjusting unit is connected with the machine and tool mounting frame, the laser displacement measurement sensor measures displacement of the machine and tool mounting frame in the tilling depth direction, the PLC control system analyzes and processes a distance signal detected by the laser ranging sensor and a displacement signal detected by the laser displacement measurement sensor, and the machine and tool mounting frame is controlled to move up and down in the tilling depth direction. Accordingly, the tilling depth can be detected and recorded in real time, the tilling depth is automatically controlled in a certain range according to the surface relief, the surface flatness is improved, and the operation effects of shallow-tillage, deep-tillage and furrowing are improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to a universal automatic detection and control device for tillage depth, which can be universally installed on most shallow loosening machines and subsoiling machines, as well as a small number of ditch openers. Background technique [0002] Soil tillage is a basic field operation. The tillage depth is an important parameter to measure the performance of tillage machinery. Whether it is stable during the operation and whether it meets the requirements of agronomy will directly affect the tillage effect. When the plowing and preparation machinery is working in the field, due to changes in soil conditions and differences in personnel operations, the depth of plowing and preparation of the same plot is inconsistent, which directly affects the quality of work. The adjustment of the initial tillage depth is only based on the experience of the operator. The measurement method...
