Abstract

The present invention discloses a repressive force control apparatus for wheeled repression device. The control apparatus comprises a pressure sensor, a controller, and a repressive force adjustment device comprising a solenoid valve and a hydraulic oil cylinder. The control apparatus can solve the problems of poor repressive force consistency and uneasy control of the adjustment of poor repressive force value due to poor adaptability of mechanical copying mechanism to earth surface irregularities.

Description

technical field [0001] The invention relates to the field of agricultural intelligent equipment, in particular to a pressure control device suitable for a wheeled pressure device. Background technique [0002] Repression is an important part of the crop sowing process. Suppression makes the seeds in close contact with the soil, which is beneficial for the seeds to absorb water and germinate. Suppression can provide a good growth environment for crops, ensure a better emergence rate of crops, and enhance the ability of crops to resist natural disasters. The main factor affecting the effect of repression is the pressure of soil cover. If the suppression pressure is insufficient, the phenomenon of "hanging roots" will easily appear after the seeds germinate; if the suppression pressure is too high, it will easily cause topsoil compaction and hinder the emergence of seeds on top of the soil. In short, excessive or insufficient suppression pressure will affect the emergence ra...
