Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transportation machinery, etc. In a broad sense, agricultural machinery also includes forestry machinery, fishery machinery and rural sideline machinery such as sericulture, beekeeping, and edible fungus cultivation. Agricultural machinery is a relative concept, referring to the general term for all machinery used in agriculture, animal husbandry, forestry and fishery. Agricultural machinery belongs to the category of agricultural machinery and tools. The promotion of the use of agricultural machinery is called agricultural mechanization.

[0003] The cockpit of agricultural machinery is equipped with a special seat for the driver to sit on. However, the existing agricultural machinery seats mostly use springs in the shock-absorbing structure. The springs are directly connected to the base of the seat, which has large resistance during shock absorption, is relatively hard, and is not comfortable enough. It is also easy to produce abnormal noise during long-term use, and the installation method is relatively fixed, which is inconvenient to replace. Therefore, the utility model proposes a shock-absorbing device for the cockpit seat of agricultural machinery to solve the problems existing in the prior art. Utility Model Content

[0031] Both ends of the frame 3 are provided with side frames 7, and the inside of the side frames 7 is provided with a slide groove 8, and the inside of the slide groove 8 is elastically provided with a slider 9, and both sides of the bottom of the seat plate 1 and both sides of the top of the base 2 are hinged with connecting arms 10, and the outer ends of the connecting arms 10 on both sides are respectively hinged with the sliders 9 at both ends. When in use, when the seat plate 1 is under load, the first plug block 4 is pressed down, the frame 3 moves down, the magnets 6 on the first plug block 4 and the second plug block 5 are close to each other, and the same poles repel each other to perform magnetic shock absorption, and the synchronous connecting arm 10 rotates, so that the slider 9 moves elastically in the slide groove 8 to perform elastic shock absorption, and the double shock absorption is coordinated, the effect is better, and it is not directly connected with a spring, and the overall shock absorption effect tends to be soft, which is more comfortable.

[0032] A cushion 11 is disposed on the top of the seat plate 1, and a backrest 12 is connected to the rear end of the cushion 11. A user sits on the cushion 11, leans against the backrest 12, and uses the agricultural machine.

[0033] A spring 17 is connected between the outer end of the slider 9 and one end inside the slide slot 8, and a soundproof sleeve 18 is sleeved on the outer end of the side frame 7, and the soundproof sleeve 18 is covered at the position of the spring 17. When the seat plate 1 is under load, the first plug 4 is pressed down, the frame 3 moves down, and the connecting arm 10 rotates, so that the slider 9 moves in the slide slot 8, squeezes the spring 17, and performs elastic shock absorption.
