[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention arranges first fixing plates at both ends of the bottom plate, a fixing groove is arranged inside the first fixing plate, a second fixing plate is arranged in front of the connecting sleeve, and a fixing hole is arranged inside the second fixing plate, thereby facilitating the connection between the bracket and the agricultural machinery and the cab, making the bracket easy to disassemble and assemble, reducing the installation technical content, reducing the disassembly and assembly cost, and improving the disassembly and assembly efficiency.

[0015] 2. The present invention installs a shock-absorbing pillar on the top of the bottom plate, and a receiving plate is arranged on the top of the shock-absorbing pillar. The receiving plate is used to receive the cab and provide support for the cab. The shock-absorbing spring has good elasticity and the ability to recover deformation, which can achieve good shock-absorbing effect, thereby reducing the vibration generated during the operation of the agricultural machinery, reducing the impact of the vibration on the cab, and ensuring the stability of the cab operation. At the same time, a clamping plate is arranged on the outside of the lower end of the shock-absorbing column, and the clamping plate is fixed to the sleeve by a limit spring, which can improve the shock-absorbing effect of the shock-absorbing pillar, and limit the shock-absorbing column to ensure the stability of the shock-absorbing column during operation. A second rolling groove is arranged on the inner wall of the clamping plate, and a second ball is installed inside the second rolling groove. The second ball can generate rolling friction with the shock-absorbing column, thereby reducing friction resistance and facilitating the movement of the shock-absorbing column.

[0016] 3. The present invention installs an auxiliary shock-absorbing box behind the shock-absorbing pillar, and the connecting sleeve is rotatably connected to the auxiliary shock-absorbing box through a connecting plate. When the cab is vibrated, the vibration force will be transmitted to the second fixed plate, and then transmitted to the connecting sleeve from the second fixed plate. The connecting sleeve slides, and the connecting plate rotates under the force, and pushes the sliding sleeve of the auxiliary shock-absorbing box to slide outside the sliding rod. At the same time, the buffer springs on both sides of the sliding sleeve are deformed under the force. While deforming, the buffer springs will generate a reaction force to restore the deformation, thereby reducing the force in this process, thereby achieving a good shock-absorbing effect.

[0017] 4. The present invention sets an opening at the rear end of the connecting sleeve, sets locking plates at both ends of the opening, and the two locking plates are connected by bolts, thereby facilitating the assembly of the connecting sleeve and the support column, and facilitating the disassembly and assembly of the connecting sleeve, improving the disassembly and assembly efficiency, and improving the flexibility of the bracket. A first rolling groove is set on the inner wall of the connecting sleeve body, and a first ball is installed inside the first rolling groove. The first ball can generate rolling friction with the support column, thereby reducing friction resistance, facilitating the movement of the connecting sleeve, and allowing the auxiliary shock absorbing box to play a role.

[0032] Furthermore, the first fixing plate 2 is configured as a triangular structure, which is stable, strong and not easily deformed.

[0033] Working principle: When in use, the bottom plate 1 is set on the agricultural machinery, the first fixing plates 2 on both sides are fitted with the agricultural machinery, and the bracket and the agricultural machinery are fixed through the upper fixing groove 21 of the first fixing plate 2. The cab is set at a suitable position of the agricultural machinery, the bottom of the cab is fitted with the receiving plate 8, the second fixing plate 5 is fitted with the rear end of the cab, and the bracket and the cab are fixed through the fixing hole 51. The fixing method is simple, which makes the bracket easy to disassemble and assemble, and at the same time reduces the installation technical content, reduces the disassembly and assembly cost, and improves the disassembly and assembly efficiency. During the operation of the agricultural machinery, a certain vibration will be generated, and the vibration will be transmitted to the bracket, and the auxiliary shock-absorbing box 6 and shock-absorbing pillar 7 on the bracket will play a role. When the shock-absorbing pillar 7 is vibrated, its shock-absorbing spring 74 is compressed by force, the shock-absorbing column 72 moves toward the inside of the sleeve 71, and the second ball 762 is forced to roll in the second rolling groove 761, thereby reducing the friction force. The shock-absorbing spring 74 will generate a reaction force while deforming, and then reduce the force received in this process to achieve a shock-absorbing effect. During the movement of the shock-absorbing column 72, the limit spring 77 is deformed by force and will immediately generate a reaction force, thereby increasing the shock-absorbing effect and limiting the shock-absorbing column 72 to ensure the stability of the operation of the shock-absorbing column 72 and the shock-absorbing spring 74. The connecting sleeve 4 is forced to slide outside the support column 3, and the connecting plate 9 transmits the force to the auxiliary shock-absorbing box 6. The connection between the connecting plate 9 and the first hinge seat 43 and the second hinge seat 66 rotates, and the sliding sleeve 63 is forced to slide outside the slide rod 62. The buffer springs 64 on both sides of the sliding sleeve 63 are deformed by force. At the same time, the buffer springs 64 will generate a reaction force to restore the deformation, thereby achieving the shock-absorbing and buffering effect in this process. An opening is set at the rear end of the connecting sleeve 4, and locking plates 44 are set at both ends of the opening. The two locking plates 44 are connected by bolts, thereby facilitating the assembly of the connecting sleeve 4 and the support column 3, and facilitating the disassembly and assembly of the connecting sleeve 4, improving the disassembly and assembly efficiency, and improving the flexibility of the bracket. A first rolling groove 411 is provided on the inner wall of the sleeve body 41 of the connecting sleeve 4, and a first ball 412 is installed inside the first rolling groove 411. The first ball 412 can generate rolling friction with the support column 3, thereby reducing friction resistance, facilitating the movement of the connecting sleeve 4, and enabling the auxiliary shock absorbing box 6 to function.
