Description

Technical Field

[0001] This utility model relates to the field of vertical drive rake technology, specifically a vertical drive rake protection mechanism. Background Technology

[0002] In the field of agricultural machinery, the side baffles of vertical drive harrows are key components for soil agglomeration, and they are usually used to ensure the uniformity and efficiency of tillage operations by limiting soil flow.

[0003] In existing technologies, side baffles mostly adopt a fixed rigid installation structure and lack adaptive buffer design. When the equipment moves and drives the side baffle to move, if there are hard foreign objects such as stones or hardened soil blocks in the path, the direct collision between the side baffle and the foreign objects can easily cause local dents or overall deformation, which will damage the soil gathering function of the side baffle and affect the uniformity of soil distribution within the tillage area.

[0004] Therefore, it is necessary to propose a vertical drive rake protection mechanism to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figure 1-4As shown, a vertical drive rake protection mechanism includes a bracket 13. Protective plates 8 are provided at both ends of the bracket 13. A swing arm 3 is fixedly connected to one adjacent side of each of the two protective plates 8. The end of the swing arm 3 away from the protective plate 8 is rotatably connected to the bracket 13. U-shaped supports 5 for limiting the free end of the swing arm 3 are fixedly connected to both ends of the bracket 13. A return spring 4 is connected between the swing arm 3 and the U-shaped support 5, and the return spring 4 is used to drive the swing arm 3 to return to its original position. Specifically, the swing arm 3 is hinged to the bracket 13, and the U-shaped support 5 is fixed to the bracket 13 by welding. A gap is provided between the protective plates 8 and the bracket 13 to prevent the bracket 13 from interfering with the vertical movement of the protective plates 8.

[0028] During the operation of the vertical drive rake, when a hard foreign object is present in the moving path of the protective plate 8, the protective plate 8 moves upward due to the obstruction of the foreign object. The protective plate 8 drives the swing arm 3 to rotate upward, and the return spring 4 is stretched by force. After the protective plate 8 passes the foreign object, the return spring 4 drives the swing arm 3 to rotate and return to its original position. With this cooperation, the protective plate 8 is prevented from being deformed by collision. By using a U-shaped support 5 to limit the free end of the swing arm 3, the swing arm 3 can be prevented from swinging back and forth during rotation, and the rotation angle of the swing arm 3 can be limited.

[0029] In order to enable the protective plate 8 to float upward quickly when it encounters a foreign object, a slope 14 is provided on the lower front side of the protective plate 8. When the foreign object comes into contact with the slope 14, the inclined guiding effect of the slope can convert the impact force of the foreign object into an upward component force, thereby pushing the protective plate 8 to move upward.

[0030] To ensure force balance on both sides of the swing arm 3, two return springs 4 are provided, symmetrically distributed on both sides of the swing arm 3. Preferably, when the swing arm 3 is in the initial position, the return springs 4 are in a slightly stretched state.

[0031] In some embodiments, one end of the return spring 4 is fixedly connected to the swing arm 3 by the first fixing bolt 2, and the other end of the return spring 4 is connected to the U-shaped support 5 by the connecting piece 10. The two ends of the connecting piece 10 are respectively provided with a hanging hole 9 and a strip-shaped through hole 12. The return spring 4 is connected to the connecting piece 10 through the hanging hole 9, and the connecting piece 10 is sleeved on the top end of the U-shaped support 5 through the strip-shaped through hole 12.

[0032] When installing the reset spring 4, hook one end of the reset spring 4 onto the outside of the first fixing bolt 2, and then tighten it with a nut. Pass the other end of the reset spring 4 through the hanging hole 9 through the connecting piece 10, and then put the connecting piece 10 through the strip-shaped through hole 12 onto the top of the U-shaped support 5 to complete the installation of the reset spring 4.

[0033] To prevent the connecting piece 10 from falling off, a limiting groove 11 is provided on the side of the top of the U-shaped support 5 away from the reset spring 4. After the connecting piece 10 is sleeved on the outside of the U-shaped support 5, it slides downward to the limiting groove 11. Under the action of the tension of the reset spring 4, the connecting piece 10 is locked into the limiting groove 11. Under the limitation of the limiting groove 11, the connecting piece 10 is prevented from sliding upward and falling off.

[0034] In some embodiments, to facilitate maintenance and replacement of the protective plate 8, the swing arm 3 is fixedly connected to the protective plate 8 by a second fixing bolt 6, which passes through the protective plate 8 via a slotted hole 7. Specifically, there are multiple slotted holes 7, which are spaced apart along the vertical direction. By providing multiple slotted holes 7, the installation height of the protective plate 8 can be controlled as needed.

[0035] 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.
