[0020] The replacement mechanism includes a mounting seat 8, a connecting rod 9, a positioning hole 10, a cavity 11, a positioning pin 12 and a telescopic spring 13. The mounting seat 8 is arranged above the side plate 2, and a connecting rod 9 is arranged inside the mounting seat 8. The top of the connecting rod 9 is connected to the bottom end of the protective steel plate 6, and a positioning hole 10 is opened inside the connecting rod 9. A cavity 11 is installed on one side of the mounting seat 8, and a positioning pin 12 is arranged throughout the interior of the cavity 11. One end of the positioning pin 12 extends to the interior of the positioning hole 10, and a telescopic spring 13 is arranged on the outer wall of the positioning pin 12. The telescopic spring 13 is installed in the interior of the cavity 11. Four mounting seats 8 are arranged above the side plate 2, and the four mounting seats 8 are symmetrically distributed about the central axis of the side plate 2. The inner diameter of the positioning hole 10 is larger than the outer diameter of the positioning pin 12, and a snap fit is formed between the positioning hole 10 and the positioning pin 12 When the protective steel plate 6 is damaged and needs to be replaced, the positioning pin 12 is pulled outward so that the positioning hole 10 is disengaged from the positioning pin 12. At this time, the connecting rod 9 can be taken out from the inside of the mounting seat 8, and the protective steel plate 6 can be removed. Then the above-mentioned operation steps are repeated to complete the convenient installation of the protective steel plate 6. The protective steel plate 6 can be conveniently disassembled and installed, making it more convenient and quick to replace the protective steel plate 6 after damage, and also improving the protection of the farmer's cab, thereby greatly improving the safety of the agricultural machinery cab when in use.

[0021] The buffer mechanism includes a damper 14, a return spring 15, a mounting plate 16, a support rod 17 and a limiting structure. The damper 14 is installed at the bottom end of the mounting cavity 7. The outer wall of the damper 14 is provided with a return spring 15. The top of the damper 14 is provided with a mounting plate 16. The top of the mounting plate 16 is provided with a support rod 17. The top of the support rod 17 extends to the outside of the mounting cavity 7. The top of the support rod 17 is connected to the bottom end of the mounting seat 8. When a heavy object falls and hits the protective steel plate 6, the support rod 17 is driven by pressure to move the mounting plate 16 downward. At this time, the return spring 15 is provided on the outer wall of the damper 14. The top of the damper 14 is provided with a mounting plate 16. The top of the mounting plate 16 is provided with a support rod 17. The top of the support rod 17 extends to the outside of the mounting cavity 7. The top of the support rod 17 is connected to the bottom end of the mounting seat 8. When a heavy object falls and hits the protective steel plate 6, the support rod 17 is driven by pressure to move the mounting plate 16 downward. The positioning spring 15 is acted upon by elastic force, and with the cooperation of the damper 14, the positioning rod 18 and the positioning sleeve 19 are utilized to limit the mounting plate 16 and the support rod 17, thereby alleviating the pressure on the support rod 17, and further alleviating the impact force on the protective steel plate 6, thereby protecting the agricultural machinery cab. At the same time, the inclined design of the protective steel plate 6 makes it difficult for heavy objects to stay above the protective steel plate 6, and they can roll down quickly, thereby alleviating the pressure on the protective steel plate 6, achieving the effect of buffering and shock absorption, and protecting the agricultural machinery cab, thereby greatly improving the practicability of the agricultural machinery cab during use.

[0022] The limiting structure includes a limiting rod 18 and a limiting sleeve 19. The limiting rod 18 is installed on both sides inside the mounting cavity 7. The outer wall of the limiting rod 18 is provided with a limiting sleeve 19. One side of the limiting sleeve 19 is connected to one side of the mounting plate 16. The cross-section of the limiting rod 18 is smaller than the cross-section of the limiting sleeve 19. A sliding structure is formed between the limiting rod 18 and the limiting sleeve 19. When in use, the limiting rod 18 and the limiting sleeve 19 cooperate with each other to limit the mounting plate 16 when it moves, so that the mounting plate 16 is more stable when it moves.

[0023] Working principle: the staff takes out the protective steel plate 6, pulls the positioning pin 12 backwards, and then places the connecting rod 9 into the interior of the mounting seat 8. When the mounting seat 8 and the connecting rod 9 are engaged with each other, the positioning pin 12 is released. At this time, the telescopic spring 13 is acted upon by the elastic force to drive the positioning pin 12 to extend, so that the positioning pin 12 and the positioning hole 10 are engaged with each other, completing the convenient installation of the protective steel plate 6. When a heavy object falls and hits the protective steel plate 6, the support rod 17 is acted upon by the pressure to drive the mounting plate 16 to move downward. At this time, the reset spring 15 is acted upon by the elastic force, and with the cooperation of the damper 14, the limit rod 18 and the limit The limiting function of the sleeve 19 drives the mounting plate 16 and the support rod 17 to move, thereby alleviating the pressure on the support rod 17, and further alleviating the impact force on the protective steel plate 6, thereby protecting the agricultural machinery cab. At the same time, the inclined design of the protective steel plate 6 makes it difficult for heavy objects to stay above the protective steel plate 6 and can roll down quickly. When the protective steel plate 6 is damaged and needs to be replaced, the positioning pin 12 is pulled outward to disengage the positioning hole 10 from the positioning pin 12. At this time, the connecting rod 9 can be taken out from the inside of the mounting seat 8, and the protective steel plate 6 can be removed. Then, the above-mentioned operation steps are repeated to complete the convenient installation of the protective steel plate 6.
