[0055] Working principle:

[0056] When the ridge clearing mechanism starts working, the main support is connected to the traction equipment through the front end to provide stable traction. The adjustable disc assembly contacts the ground, and the disc assembly moves up and down according to the terrain and soil hardness. The up and down movement of the disc assembly is transmitted to the mounting seat 2 through the connecting arm 4, so that the mounting seat 2 rotates around the hinge shaft 21. The rotation of the mounting seat 2 causes the expansion and contraction amount of the spring arm structure 3 to change, and the spring arm structure 3 automatically adjusts the pressure on the mounting seat 2 according to the change in expansion and contraction amount. The spring arm structure 3 applies downward pressure to the mounting seat 2 through the compression and release of the spring 302. This pressure is transmitted to the adjustable disc assembly through the connecting arm 4, so that the disc knife 7 maintains appropriate pressure in contact with the ground to achieve an ideal ridge clearing effect. The relatively adjustable disc assembly can move up and down according to the undulations of the terrain, which also ensures the continuity and stability of the ridge clearing work.

[0057] By adjusting the first arc-shaped guide rail hole 222 on the hole plate 22, the relative angle between the connecting arm 4 and the mounting seat 2 can be adjusted, thereby changing the width of the ridge clearing.

[0058] The installation angle of the connecting shaft 6 can be adjusted through the second arc-shaped guide rail hole 51 on the fixing member 5, and the working angle of the disc knife 7 can be further optimized, so that the ridge clearing mechanism can adapt to different working conditions.

[0059] Working process:

[0060] Before starting the operation, according to the soil hardness and topography of the working plot, adjust the nut on the spring arm structure 3 to preset the compression degree of the spring 302. Adjust the angle of the connecting arm 4 and the adjustable disc assembly to ensure that the disc knife 7 can adapt to the width of the plot and the required working angle.

[0061] When working, the ridge clearing mechanism is connected to the traction device and starts to be pulled. The disc knife 7 starts to clear the straw and weeds on the surface. During the working process, the spring arm structure 3 can adjust the downward pressure of the disc knife 7 according to the ups and downs of the terrain.

[0062] After completing the ridge clearing operation, disconnect the ridge clearing mechanism from the traction equipment, perform cleaning and maintenance, and prepare for the next operation.

[0063] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
