Abstract

The invention provides a method and device for controlling the rotating speed of a roller, and relates to the technical field of agricultural machine control. The method for controlling the rotating speed of the roller comprises the steps that information of the rotating speed of the roller is input into a controller through a roller rotating speed sensor the controller compares the rotating speedof the roller with target rotating speed, and a rotating speed deviation value is obtained; the controller outputs a speed regulating signal according to the rotating speed deviation value, and sendsthe speed regulating signal to a corresponding speed regulating solenoid valve; after the speed regulating solenoid valve receives the speed regulating speed signal, the rotating speed of the rolleris regulated, so that the rotating speed of the roller is equal to the target rotating speed. According to the method and device, the technical problems that the rotating speed control precision of the roller of an agricultural machine is not high, and the rotating speed of the roller is not constant are solved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery control, in particular to a method and device for controlling the rotating speed of a drum. Background technique [0002] In recent years, the state has increased its support for agriculture in terms of policies, increased investment in the economy, and increased project support in terms of technology. In view of the support of national policies, land intensification has become more and more important in agricultural development, and land cultivation has gradually shifted from small workshops to industrial production. The intensification of land stimulates more young people to start farming, and at the same time, there is an increasing demand for the efficiency, economy and comfort of agricultural machinery. [0003] At present, the harvester is no longer just for a certain crop, but a real grain combine harvester, which can harvest corn, soybeans, rice, wheat, rapeseed, sunflower ...
