Large rice direct seeding operation unit control device and method based on Beidou system

Abstract

The invention provides a large rice direct seeding operation unit control device and method based on a Beidou system. The device comprises a tractor body, an operation unit, a lifting oil cylinder and a leveling oil cylinder, wherein the tractor body is provided with a controller, a lifting valve set, a leveling valve set and a tilt angle sensor A for collecting attitude signals of the tractor body, the operation unit is provided with a tilt angle sensor B for collecting attitude signals of the operation unit and a floater sensor for collecting relative positions of the operation unit and the water surface, and the controller is used for receiving signals of the tilt angle sensor A, the tilt angle sensor B and the floater sensor, can control the leveling oil cylinder to act through the leveling valve set to achieve leveling control over the operation unit and can control the lifting oil cylinder to act through the lifting valve set to achieve he operation control of the operation unit close to the water surface. According to the device and the corresponding controllable method, the operation unit can be kept horizontal all the time in the operation process, meanwhile, the operation unit can be automatically attached to the water surface for operation, the operation quality is guaranteed, and the operation efficiency is improved.

Description

technical field [0001] The invention mainly relates to the technical field related to agricultural machinery, in particular to a control device and method for a large-scale rice direct seeding operation unit based on the Beidou system. Background technique [0002] At present, most rice production adopts machine-transplanted seedlings. The production cost of this production method is high, and the production links are many and complicated. In some southern regions, the sprouted rice seeds have been directly sown into paddy fields one month in advance to reduce production costs and improve operational efficiency. Basic requirements for direct seeding of rice: it is best to bury rice seeds 1~2cm to improve the survival rate. [0003] At present, the rice direct seeding machine is drawn by a three-point suspension of the tractor, and the height of the direct seeding machine is controlled by the lifting handle of the tractor. It is very difficult for a tractor driver to guaran...

AI Technical Summary

Problems solved by technology

It is very difficult for tractor drivers to maintain such precise maneuvers

In addition, due to the left-to-right or front-to-back unevenness of the hard ground under the paddy field silt, it will cause the entire operating unit to pitch back and forth and shake left and right during the operation of the tractor; , causing loss
