Embodiment Construction

[0037] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] Such as Figure 1~3 As shown, an automatic control and adjustment device for tillage depth includes a mechanical unit and a control unit.

[0039] The mechanical unit includes a vertical suspension frame 1, a pull rod 2, a profiling wheel 3, an electric push rod 4, a soil loosening shovel 5, an extension spring 10 and a profiling wheel frame 11; the device can be articulated on a tractor through the suspension frame 1.

[0040] The front end of pull rod 2 is hinged on the vertical suspension frame 1, and the hinge point of pull rod 2 and vertical suspension frame 1 is upper hinge point A, and the rear end of pull rod 2 is articulated with tillage parts. Preferably, in this embodiment, the cultivating parts are soil loosening blades 5 . The angle between the upper surface of the pull rod 2 and the...

Abstract

The invention belongs to the field of agricultural machine, and particularly relates to a tilling depth automatic control and adjustment device. The tilling depth automatic control and adjustment device comprises a mechanical unit and a control unit. The control unit comprises a first tilt angle sensor (6), a second tilt angle sensor (7), a rotary encoder (8) and a controller (9). The first tilt angle sensor (6) is arranged on a pull rod (2). The second tilt angle sensor (7) is arranged on a contour wheel frame (11). A rotating shaft of a contour wheel (3) is provided with the rotary encoder (8). An electric push rod (4), the first tilt angle sensor (6), the second tilt angle sensor (7) and the rotary encoder (8) are all electrically connected with the controller (9). The tilling depth automatic control and adjustment device is simple in structure, accurate in tilling depth adjustment and automatic in tilling depth control and adjustment. By means of the method of detecting the surfacerelief by the contour wheel and telescopically adjusting the tilling depth by the electric push rod, the tilling depth automatic control and adjustment are realized.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to an automatic control and adjustment device for tillage depth and a control method thereof. Background technique [0002] The consistency of tillage depth is an important index to measure the quality of tillage. The traditional tillage depth adjustment method uses manual control and adjustment of the tillage depth. The driver pre-sets the length of each tie rod and then controls it by the hydraulic suspension device. Sometimes it is difficult for the driver to perceive the ground. Ups and downs, resulting in inconsistent plowing depth. Shallow plowing is not conducive to crop growth; large plowing depth will increase the operation resistance of equipment, increase the power consumption of tractors, and artificial adjustment is labor-intensive and the control is not accurate. At present, the real-time monitoring and automatic adjustment technology of plowing depth...
