Technical Field

The invention belongs to agricultural machinery, and mainly relates to a part for preparing soil of various bed strips.

Background

The consistency and the stability of the width of the seedbed strip are one of important indexes for evaluating the operation quality of the seedbed straw clearing device. In the operation of cultivating and preparing the seedbed strips, the consistent and stable straw clearing width of the seedbed strips can ensure that the soil loosening and crushing device can complete the soil loosening and crushing operation under good working conditions, so that the operation quality and effect of cultivating and preparing the seedbed strips are improved. However, due to the influence of various factors such as height fluctuation and poor flatness of the field surface, straw residue coverage, different straw lengths, uneven throwing and laying and the like, the phenomena of poor stability of the depth of the arc-shaped sawtooth straw cleaning disc into the soil and inconsistent width of straw cleaning operation are easy to occur during the operation of the currently used straw cleaning device for the seedbed belts, the straw cleaning operation quality of the seedbed belts is reduced, the completion of subsequent seed sowing and fertilizing operations is not facilitated, and the sowing and fertilizing operation effects are influenced.

The invention aims to provide an automatic regulating and controlling monomer for the width of straw-clearing bedbands by combining the actual requirements of agricultural production operation aiming at the problems in the prior art, and the aims of strong adaptability, high regulating and controlling automation degree, high straw-clearing operation quality and good uniformity of the width of the seedbeds are fulfilled.

The purpose of the invention is realized as follows: a parallel four-bar frame is fixedly arranged on a single frame, two cambered surface-shaped sawtooth straw cleaning discs are rotatably assembled on the lower part of the rear side of the parallel four-bar frame in a front-back staggered manner through a disc frame and are inclined with each other, an electric linear push rod is vertically hinged on the lower side part of the upper end of the parallel four-bar frame, an S-shaped pressure sensor is hinged on the upper end part of the lower side of the parallel four-bar frame through a lower connecting piece, an upper connecting piece is arranged at a position between the lower part of the electric linear push rod and the upper part of the S-shaped pressure sensor and is connected with the S-shaped pressure sensor through the upper connecting piece, a width controller consists of a relay module, a microcontroller, a transmission amplifier, a display screen and a key module, the microcontroller is respectively communicated with the relay module, the transmission amplifier, the display screen and the key module through wires, and the electric linear push rod and the S-shaped pressure sensor are respectively communicated with the relay module and the transmission amplifier of the width, thus forming a seed bed with automatic straw width regulation and control unit.

The invention adopts the cooperation of the electric linear push rod and the S-shaped pressure sensor, solves the technical problems of poor stability of the soil penetration depth of the straw cleaning disc and inconsistent width of the straw cleaning disc when the straw is covered and is operated in the field in the prior art, ensures the stable and consistent width of the straw cleaning of the seedbed belt, provides high-quality seedbed conditions for crop seeding and fertilizing operation, and has the characteristics of simple and reasonable structure, high regulation and control automation degree, strong adaptability and good straw cleaning effect.
