Abstract

The invention provides an automatic tilling depth control device applied to a tillage machine tool. The device comprises a tilling depth feedback mechanism, a control block, a pull line and a hydraulic valve. The tilling depth feedback mechanism comprises a rack and a gear engaged with the rack. The rack is vertically arranged and connected to a machine frame in a vertically-moving mode, a land wheel is arranged at the lower end of the rack, the gear is installed on a shaft seat on the machine frame through an axle, and a reel is arranged on the axle. The lower portion of the control block is installed on an installing seat through a pin shaft, the upper portion of the front side of the control block is connected with the portion, located on the front side of the control block, of the installing seat through a reset spring, a convex body is arranged in the middle of the rear side of the control block, a valve element of the hydraulic valve is connected with an outwards-stretching rod making contact with the rear end of the convex body, and the outwards-stretching rod is sleeved with a valve element spring. One end of the pull line is connected to the reel, and the other end of the pull line is connected to the upper portion of the rear side of the control block. The change of the tilling depth state can be precisely fed back in good time, a hydraulic suspension lifting device is automatically controlled, and therefore consistent tilling depth can be kept when the machine tool works.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an automatic control device for tillage depth applied to tillage machinery. 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 shall...
