A seed bed with straw clearing width automatic regulation unit

Abstract

The utility model relates to an automatic regulating unit with straw clearing width of a seed bed belonging to an agricultural machine; an electric linear push rod is vertically hingedly installed on the lower side of the upper end of a parallel four-bar frame, and passes through a lower connecting piece on the upper end of the lower side of the parallel four-bar frame. Hinged S-type pressure sensor, the upper connector connects the electric linear actuator to the S-type pressure sensor, and the wire connects the electric linear actuator and the S-type pressure sensor to the width controller respectively, and the width controller is controlled by the relay module , micro-controller, transmission amplifier, display screen and button module; this single unit is selected based on the design basis that the width of the seed bed belt is only related to the depth of the arc-shaped sawtooth cleaning disc, and the electric linear push rod and S The cooperative structure of the type pressure sensor can adjust in real time and ensure the consistency of the width of the seed bed belt for straw cleaning. The structure is simple and reasonable, the degree of control automation is high, the adaptability is strong, and the straw cleaning effect is good.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a seed bed strip soil preparation operation part. Background technique [0002] The consistency and stability of the strip width of the seed bed is one of the important indicators for evaluating the operation quality of the seed bed straw cleaning device. In the seedbed strip plowing operation, the consistent and stable width of the seedbed strip can ensure that the loosening and crushing devices can complete the loosening and crushing operations under good working conditions, so as to improve the seedbed strip The quality and effectiveness of tillage operations. However, due to the ups and downs of the field surface, poor flatness, and the influence of many factors such as straw residue coverage, different lengths of straw, and uneven spreading and laying, the currently used seedbed with straw cleaning device is prone to camber. The poor depth stability of the sawtooth straw clea...

AI Technical Summary

Problems solved by technology

[0005] The invention uses the electric linear push rod and the S-type pressure sensor to work together, which solves the technical problems of the poor stability of the depth of the straw clearing tray and the inconsistent width of the clearing straw in the prior art when the straw is covered and returned to the field, ensuring The width of the seed bed with straw clearing is stable and consistent, providing high-quality seed bed conditions for crop sowing and fertilization operations. It has the characteristics of simple and reasonable structure, high degree of automatic control, strong adaptability, and good straw clearing effect
