[0002] In agricultural production, the disc harrow, as an important tillage implement, is widely used for tasks such as loosening soil after plowing, weeding, and shallow tillage and stubble removal after harvest. It plays a crucial role in meeting the agronomical requirements for pre-sowing land preparation. With the advancement of agricultural modernization, higher demands are being placed on the performance and adaptability of the disc harrow.

[0003] A common disc harrow consists of a harrow assembly made up of multiple concave discs fixed on a horizontal shaft. When pulled by a tractor, the discs cut into the soil through their blades, cutting grass roots or crop residues, chopping up the tilled clods, and using the concave surfaces of the discs to lift and then roll the clods down, thus achieving the effects of tilling and covering the soil.

[0004] However, when it comes to operations in complex terrains such as hilly and mountainous areas, the terrain is undulating and varied, including slopes at different angles, uneven ground, and local pits and bumps. Most existing disc harrows cannot effectively adjust their position to adapt to these complex terrains, which affects the harrowing effect, causes the soil to become loose and uneven, and may also cause excessive wear and damage to the disc harrow itself, reducing its service life.

[0005] Therefore, a disc harrow for use in hilly and mountainous areas is proposed to address the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 5 As shown, this utility model provides a disc rake for use in hilly and mountainous areas, including a V-shaped frame body 1, a support 12 hinged to one end of the V-shaped frame body 1, and a disc rake 13 disposed at the bottom of the support 12.

[0027] The surface of the V-frame body 1 is equipped with an adapter adjustment assembly 2. The adapter adjustment assembly 2 includes a hydraulic cylinder 21 symmetrically hinged to the surface of the V-frame body 1, a connecting frame 22 rotatably connected to the surface of the bracket 12, a V-plate 23, a connecting block 24, a threaded rod 25, a shock-absorbing device 26, a nut 28, and a connecting seat 29 for adapter adjustment.

[0028] V-plate 23 is hinged to the surface of V-frame body 1. The telescopic end of hydraulic cylinder 21 is hinged to V-plate 23. Two connecting seats 29 are symmetrically installed on the surface of bracket 12. Threaded rod 25 is slidably connected inside connecting seat 29. Connecting block 24 is hinged to the other end of V-plate 23. Both ends of threaded rod 25 pass through connecting seat 29. One end of threaded rod 25 is connected to connecting block 24. The other end of threaded rod 25 extends to the top of connecting seat 29. Two shock absorbers 26 are symmetrically slidably connected to the surface of threaded rod 25. Two nuts 28 are threaded to both ends of threaded rod 25, enabling effective harrowing of hilly soil, achieving good adaptation to different terrains, improving tillage quality and efficiency, and effectively extending the service life of the device.

[0029] The adjacent ends of the two shock absorbers 26 are in contact with the connecting seat 29, and the opposite ends of the two shock absorbers 26 are in contact with the nut 28, so that the positions of the two shock absorbers 26 can be fixed, thereby driving the connecting frame 22 to be lifted.

[0030] Two damping devices 26 are located above and below the connecting seat 29, respectively, so that the upper and lower parts of the connecting seat 29 can be supported and damped.

[0031] The disc rake 13 is installed on the bottom surface of the connecting frame 22, so that the position of the disc rake 13 can be adjusted to adapt to different terrains and soils.

[0032] A connection stabilization assembly 3 is installed on the surface of the first connecting frame 22. The connection stabilization assembly 3 includes a shock-absorbing device 31 symmetrically hinged to the surface of the bracket 12, a hinge seat 32 installed on the surface of the first connecting frame 22, and a connecting rod 33, a ball seat 34, a second connecting frame 35, a second disc rake 36, and a drive wheel 37 for connection stabilization.

[0033] The shock absorber 31 is hinged to the hinge seat 32. The connecting frame 35 is hinged to the surface of the connecting frame 22. Spherical seats 34 are symmetrically installed on the surfaces of the connecting frame 35 and the connecting frame 22. The connecting rod 33 is hinged between the two spherical seats 34. The driving wheel 37 is installed on the surface of the connecting frame 35. The disc harrow 36 is installed on the bottom surface of the connecting frame 35. This allows the connecting frame 22 and the connecting frame 35 to be effectively connected and can be adapted to different terrains, further improving the quality and efficiency of cultivation and enhancing the stability of the connection.

[0034] The spherical seat 34 and the connecting rod 33 are hinged together by a spherical structure, which enables the connecting frame 22 to be adjusted in angle.

[0035] Among them, the hydraulic cylinder 21, shock absorber 26, shock absorber 31 and drive wheel 37 are existing technologies, and their working principles are known technologies. The appropriate model is selected according to the actual use.

[0036] The disc rake 13 and disc rake 26 in this device are existing technologies and are the same as most on the market. For details, please refer to the existing technologies.

[0037] Working principle and process: First, the work vehicle is connected to the V-frame body 1. Then, the work vehicle drives the device to move. During the movement, the drive wheel 37 supports the device.

[0038] Before driving, the hydraulic cylinder 21 is activated. The extension or retraction end of the hydraulic cylinder 21 extends or retracts, pushing the V-plate 23 hinged to the surface of the V-frame body 1 to rotate, thereby changing the tilt angle of the V-plate 23. During the rotation of the V-plate 23, the connecting block 24 drives the threaded rod 25 to move, so that the threaded rod 25 drives the bracket 12 and the connecting frame 22 to adjust their positions as a whole through the connecting seat 29. By rotating the nuts 28 at both ends of the threaded rod 25, the nuts 28 stabilize the positions of the two shock absorbers 26, thereby pushing the bracket 12 to move, so that the disc rake 13 can be embedded in the soil or lifted.

[0039] The second shock absorber 26 can absorb the vibration and impact from the ground during operation. The two shock absorbers 26 are located above and below the connecting seat 29 respectively, with one adjacent end in contact with the connecting seat 29 and the other end in contact with the nut 28. This can effectively reduce the impact of vibration on the structure and ensure the stability after adjustment.

[0040] When the device operates in hilly and mountainous terrain, it encounters changes in terrain. The shock-absorbing device 31, which is hinged to the surface of the support 12, can buffer the vibration of the support 12 and reduce the transmission of vibration to the connecting frame 22 and the disc harrow 13. At the same time, the connecting frame 22 and the connecting frame 35 are connected to the connecting rod 33 through the hinge seat 32 and the ball seat 34. The spherical hinge structure between the ball seat 34 and the connecting rod 33 allows the connecting frame 22 to rotate on the surface of the support 12, so that the connecting frame 22 can rotate flexibly in multiple directions. This drives the disc harrow 13 installed on its bottom surface to adjust its position in real time according to the changes in terrain, so as to effectively harrow and till the soil in hilly and mountainous areas, achieve good adaptation to different terrains, and improve the quality and efficiency of tillage.

[0041] The disc harrow 36 on the connecting frame 2 35 further harrows the soil.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
