Description

Tilling depth adjusting and stabilizing device for agricultural machinery working machine

Technical Field

The utility model relates to the field of agricultural machinery, more specifically say, relate to agricultural machinery operation machines and tools depth of plowing is adjusted and depth of plowing is stable.

Background

When the agricultural machinery working implement works, such as plowing, rotary tillage, ditching, ridging and the like, the tillage depth of the working implement is often required to be adjusted according to different plots and crops to be planted, and the relative stability of the tillage depth can be kept when the agricultural machinery working implement works on uneven plots. Although the hydraulic suspension device of the current large and medium-sized tractor is provided with the position adjusting mechanism and the force adjusting mechanism to realize the tilling depth adjustment and tilling depth stability control of agricultural machinery operation tools, the hydraulic suspension device has the advantages of complex structure, heaviness, large volume, high cost and the like, and cannot be used for hitching operation tools of power tractors such as small farmlands, orchards and the like. Therefore, there is a need for a simple and portable device for adjusting and stabilizing the tilling depth of an agricultural machine working implement, which can replace the position adjusting mechanism and the force adjusting mechanism of a large and medium tractor and can also provide a device for adjusting and stabilizing the tilling depth by hooking the working implement by a small power tractor.

Disclosure of Invention

The technical scheme of the tilling depth adjusting and stabilizing device for the agricultural machinery operation machine is as follows: the invention mainly comprises an angle sensor, a relay, an electromagnetic hydraulic valve, a hydraulic oil cylinder, an adjusting handle and a sensor box, and the key technical measures are as follows: the angle sensor is arranged in the sensor box in a floating mode, and the adjusting handle controls the installation angle of the angle sensor. The sensor box is fixed on the operation machine, the position of the angle sensor can change the relative included angle between the angle sensor and the operation machine through the adjusting handle according to the operation requirement, and the tilling depth control of the operation machine is realized. The electrical signal output of the angle sensor is preset, namely: the angle sensor is horizontally (or vertically) placed, when the initial position of the angle sensor is set to be at the horizontal (or vertical) position, no electric signal is output, when the position of the angle sensor deviates from the horizontal (or vertical) direction to form a certain included angle, the electric signal is sent to the relay, the relay is connected with a power supply at one end of the electromagnetic hydraulic valve, a corresponding hydraulic oil channel is opened, hydraulic oil enters a lower cavity or an upper cavity of the hydraulic oil cylinder to push a piston of the hydraulic oil cylinder to move upwards or downwards, so that a working part of an operating machine connected with the piston is pushed to move upwards or downwards, the angle sensor arranged on the operating machine is kept at the horizontal (or vertical) position, and the tilling depth of the operating machine. Furthermore, the angle sensor rotates around a fixed shaft, and the angle sensor is limited to rotate only, so that other degrees of freedom are restricted. Furthermore, the angle sensor is connected with the adjusting handle through a steel wire rope, and the adjusting handle is rotated to drive the angle sensor through the steel wire rope so as to change the angle position of the angle sensor. The position of the angle sensor can be adjusted by connecting the steel wire rope, the angle sensor can be further far away from the adjusting handle, the adjusting handle is convenient to install near an operator, and the operator can conveniently operate the angle sensor in real time. The invention has the following beneficial effects: the invention uses the angle sensor and adopts the floating installation technology, can replace the traditional position adjusting mechanism and force adjusting mechanism of the tractor, has simple structure and portability, solves the problems of tilling depth adjustment and tilling depth stable control of the small-sized agricultural machinery power tractor for hanging the agricultural machinery operation machine tool, and improves the operation quality and the adaptability of the agricultural machinery operation machine tool.
