Automatic tilling depth control system and method

Abstract

The invention provides an automatic tilling depth control system and method. The automatic tilling depth control system comprises a tilling depth feedback mechanism, a signal conversion mechanism, a pull wire and a control module. The tilling depth feedback mechanism comprises a pull wire signal rod which is connected to a rack in a vertically-moving mode, the lower end of the pull wire signal rod is connected with the lower side of a splash guard on the rear side of a farm implement through a pin shaft, and the upper end of the pull wire signal rod is connected with a transverse rod. The signal conversion mechanism comprises a sliding rheostat and a stabilized voltage supply, and the two poles of the stabilized voltage supply are connected to one end of a sliding rod of the sliding rheostat and one end of a resistance wire of the sliding rheostat respectively to form a tilling depth monitoring circuit. The pull wire is composed of a wire jacket and a wire core, one end of the wire jacket is fixed to a wire jacket base below the transverse rod, the other end of the wire jacket is fixed to a wire jacket base at the rear end of the sliding rod, one end of the wire core is connected with the transverse rod, and the other end of the wire core is connected with a sliding sleeve. By means of the automatic tilling depth control system and method, the tilling depth can be accurately monitored in real time, and a hydraulic suspension lifting device can be automatically controlled to lift the farm implement so that the farm implement can keep the tilling depth uniform when working.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an automatic control system and method for tillage depth. Background technique [0002] In recent years, with the support of the country's policy of vigorously promoting agricultural mechanization, medium and large agricultural machinery has developed rapidly, especially in paddy field operations in southern my country, medium and large agricultural machinery has grown rapidly. high demands. [0003] The various agricultural machinery power combinations that have been used in conjunction with agricultural machinery cannot achieve effective balanced control of the tillage depth of the machinery. Wave forward. When the machine head tilts forward, the implements suspended at the rear will be pressed down, resulting in increased plowing depth of the implements; when the unit is tilted forward, the rear implements will be lifted up, resulting in shallower plowing depth...

AI Technical Summary

Problems solved by technology

This seriously affects the uniformity of the cultivation depth of the plot and the flatness of the surface, making it difficult for the plowed land to meet the plowing requirements of the crop planting on the plot.

[0004] In the prior art, the method of tillage depth control is generally that the driver manually adjusts the handle by observing the tillage depth. The driver not only needs to invest a lot of energy to operate the agricultural machine, but also cannot monitor the tillage depth accurately in real time, and the tillage Depth control accuracy is not high
