Description

Technical Field

[0001] This utility model relates to the technical field of cutter head connection structure, specifically an adjustable and adaptable cutter head connection structure. Background Technology

[0002] In mechanized agricultural operations, the header connection structure of a harvester is a key component ensuring harvesting efficiency and operational stability. Traditional header connections often use a hinged structure, making it difficult for the header connection to accommodate the height differences of hooks on different tractor models. Forcing a higher or lower hook to match will cause the header to form an angle with the ground, affecting the quality of the header's operation and limiting its applicability. Furthermore, when operating on rough terrain, the lack of an effective buffer structure causes the impact force to be directly transmitted to the connection between the header and the hook, accelerating wear on the connection point.

[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0004] To solve the problems in the background art, the present invention is achieved through the following technical solution: an adjustable and adaptable cutting table connection structure, including a fixed frame, wherein a middle connecting frame is movably mounted on one end of the fixed frame through a first pin.

[0005] A rectangular frame is movably mounted on one end of the middle connecting frame via a second pin. Two Z-shaped frames are symmetrically mounted on the upper and lower walls of the rectangular frame. The ends of the two Z-shaped frames away from the rectangular frame are fitted together. Each end of the two Z-shaped frames away from the rectangular frame has an insertion hole. Springs are mounted on the upper and lower walls of the two Z-shaped frames coaxially with the insertion holes. An auxiliary rotation component is mounted on one end of the spring. An end limiting component is mounted on the fixed frame. A middle limiting component is installed between the middle connecting frame and the rectangular frame.

[0006] Preferably, the auxiliary rotating assembly includes a connecting plate, which is mounted on one end of a spring, and a turntable is movably inserted into the connecting plate.

[0007] Preferably, the end limiting component includes two n-shaped frames, which are symmetrically installed at one end of the fixed frame, and each n-shaped frame is fitted with a buffer sleeve.

[0008] Preferably, the middle limiting component includes a stop bar, which is installed on the inner wall of the middle connecting frame. Baffles are installed on both the upper and lower walls of the rectangular frame, and buffer pads are installed on the baffles.

[0009] Preferably, a reinforcing rib is installed between the baffle and the Z-shaped frame.

[0010] Preferably, both the fixing frame and the middle connecting frame are convex structures.

[0011] Beneficial effects

[0012] This utility model provides an adjustable and adaptable header connection structure with the following advantages: In use, the spring parts on the two Z-shaped frames are aligned with the hook parts of the tractor, and the tractor hook is inserted into the spring and the insertion hole. The middle connecting frame, the fixed frame and the rectangular frame can rotate, which can adapt to the hook parts of tractors of different heights. It has a wide range of applications and does not affect the angle between the header connected to the fixed frame and the ground. When the road surface is uneven, when the two Z-shaped frames move up and down with the hook, the auxiliary rotating component contacts the hook part, and the spring plays a buffering role to prevent the two Z-shaped frames from colliding directly with the hook part, thus protecting the appearance quality of the Z-shaped frames and the hook.

[0016] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example: Please refer to Figure 1-2 An adjustable and adaptable cutting table connection structure includes a fixed frame 1, and a middle connecting frame 2 is movably mounted on one end of the fixed frame 1 via a first pin.

[0018] It should be noted that the fixed frame 1 can be welded and installed on the cutting table, and the middle connecting frame 2 can rotate at one end of the fixed frame 1 through the first pin.

[0019] Specifically, a rectangular frame 3 is movably mounted on one end of the middle connecting frame 2 via a second pin. Two Z-shaped frames 4 are symmetrically mounted on the upper and lower walls of the rectangular frame 3. The ends of the two Z-shaped frames 4 away from the rectangular frame 3 are fitted together. Insertion holes 5 are provided on the ends of the two Z-shaped frames 4 away from the rectangular frame 3. Springs 6 are coaxially mounted on the upper and lower walls of the two Z-shaped frames 4 with the insertion holes 5. An auxiliary rotation component is mounted on one end of the springs 6. An end limiting component is mounted on the fixed frame 1. A middle limiting component is installed between the middle connecting frame 2 and the rectangular frame 3.

[0020] It should be noted that the rectangular frame 3 is used to support one end of the two Z-shaped frames 4, and is connected to the middle connecting frame 2 through the second pin, so that the middle connecting frame 2 can rotate at one end of the rectangular frame 3. When in use, the spring 6 part on the two Z-shaped frames 4 is aligned with the hook part of the tractor. Its structure and working principle are similar to those of common tractor hooks on the market, such as straight-insertion trailer arms. Since it is existing technology, it will not be described in detail here. The tractor hook is inserted into the spring 6 and the insertion hole 5. By rotating the middle connecting frame 2 between the rectangular frame 3 and the fixed frame 1, it can adapt to the hook parts of tractors of different heights, with a wide range of applications, and does not affect the angle between the cutter connected to the fixed frame 1 and the ground. When the road surface is uneven, when the two Z-shaped frames 4 move up and down with the hook, the auxiliary rotating component contacts the hook part, and the spring 6 plays a buffering role to prevent the two Z-shaped frames 4 from colliding directly with the hook part, thus protecting the appearance quality of the Z-shaped frames 4 and the hook.

[0021] Specifically, the auxiliary rotating assembly includes a connecting plate 7, which is mounted on one end of the spring 6, and a turntable 8 is movably inserted into the connecting plate 7;

[0022] It should be noted that when the two Z-shaped frames 4 rotate at the hook, under the action of gravity, the turntable 8 and the hook come into contact with each other. Under the action of friction, the turntable 8 does not move, and the connecting plate 7 rotates on the turntable 8, preventing the Z-shaped frame 4 and the hook from directly rubbing against each other and protecting the appearance quality of the Z-shaped frame 4 and the hook.

[0023] Specifically, the end limiting component includes two n-shaped frames 9, which are symmetrically installed at one end of the fixed frame 1, and each n-shaped frame 9 is fitted with a buffer sleeve 10.

[0024] It should be noted that the two n-shaped frames 9 are used to limit the maximum rotation position between the fixed frame 1 and the middle connecting frame 2, so as to prevent the fixed frame 1 and the middle connecting frame 2 from rotating excessively, and the buffer sleeve 10 is used to buffer the collision between the n-shaped frame 9 and the middle connecting frame 2.

[0025] Specifically, the middle limiting component includes a stop bar 11, which is installed on the inner wall of the middle connecting frame 2. The upper and lower walls of the rectangular frame 3 are both equipped with baffles 12, and buffer pads 13 are installed on the baffles 12.

[0026] It should be noted that the stop bar 11 and the baffle 12 are used to limit the maximum rotation position between the middle section connecting frame 2 and the rectangular frame 3 to prevent the rectangular frame 3 and the middle section connecting frame 2 from rotating excessively, and the buffer pad 13 is used to buffer the collision between the middle section connecting frame 2 and the rectangular frame 3.

[0027] Among them, the buffer pad 13 and the buffer sleeve 10 are both made of rubber material, and the turntable 8 is provided with a rubber pad to increase the friction between the turntable 8 and the hook.

[0028] As a preferred and further option, a reinforcing rib 14 is installed between the baffle 12 and the Z-shaped frame 4 to enhance the strength of the baffle 12.

[0029] As a preferred and further option, both the fixing frame 1 and the middle connecting frame 2 are convex structures.

[0030] 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.
