Description

Technical Field

[0001] The utility model relates to the technical field of seats, and more specifically to a shock-absorbing seat for a tractor. Background Art

[0002] Tractors are currently widely used in rural and urban areas. They are not only used in farmland cultivation, but also widely used in rural transportation. The working environment of tractors is poor, and drivers are often required to work on tractors for a long time. Since the various vibrations when the tractor is working are relatively large, and the seats of tractors are mostly rigidly connected, shock-absorbing seats are needed to increase the comfort of tractor use.

[0003] In the existing public documents, the utility model patent with patent publication number CN214689151U discloses a shock-absorbing seat for tractors. The current tractor seats either do not have a shock-absorbing function or add springs and sponge cushions for shock absorption. In this way, shock absorption can only be achieved directly below the seat, and the shock absorption amplitude is small. After a long time, the sponge cushion is prone to deformation, and the spring will bulge out, which weakens the shock absorption effect of the seat and affects the comfort of the seat. The driver's head and neck cannot be adjusted to a suitable angle to lean on to relieve fatigue, and a comfortable driving environment and rest environment cannot be created for the driver; the patent mainly uses springs and columns for buffering and support to avoid excessive compression of the spring resulting in a decrease in elastic potential energy; the headrest can be adjusted in angle to avoid discomfort in the head and neck caused by excessive shaking of the tractor; but the shock-absorbing seat still has the following defects;

[0004] When the shock-absorbing seat is installed on a tractor for use by an operator, the tractor operator needs to operate the tractor for a long time, and the operator's buttocks are in contact with the shock-absorbing seat for a long time, and it is difficult to create a certain gap. Therefore, it is difficult for the buttocks to be fully ventilated, which easily leads to sweat accumulation and poor riding comfort. Therefore, a tractor shock-absorbing seat is needed.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] As attached Figure 1-4 A tractor shock-absorbing seat is shown, and a multi-point ventilation component is arranged on the tractor shock-absorbing seat.

The specific structural arrangement of the multi-point ventilation component is as follows:

[0023] In some embodiments, as shown in the attached Figure 1-3 As shown, the multi-point ventilation component includes a breathable cavity plate 3 bonded and fixed to the upper surface of the silicone shock-absorbing pad 2, a plurality of upper row ventilation holes 4 are embedded in the top of the breathable cavity plate 3, a plurality of transversely spaced breathable frame strips 5 arranged equidistantly from left to right are installed above the upper row of ventilation holes 4, both ends of the transversely spaced breathable frame strips 5 are fixedly connected with lateral frame strips 6, a lateral exhaust hole 7 is penetrated through one side of the lateral frame strip 6, a booster connection hose 8 penetrating the seat support frame 1 is provided on one side of the outer wall of the breathable cavity plate 3, and a booster air pump 9 for pressurizing the air inside the breathable cavity plate 3 is threadedly connected at the top end of the booster connection hose 8;

[0024] The use principle of the shock-absorbing seat of the tractor in this embodiment is as follows: the seat support frame 1 and the support frame 10 are fixed at the installation position of the tractor head 11, and the operator's buttocks sit on the upper surface of multiple transversely spaced air-permeable frame strips 5. Under the action of gravity, the transversely spaced air-permeable frame strips 5 drive the two lateral exhaust holes 7 to squeeze the seat support frame 1 downward, and the transversely spaced air-permeable frame strips 5 drive the upper row of air holes 4 to guide the air-permeable cavity plate 3 to move downward along the inner wall of the seat support frame 1. At the same time, the shock-absorbing airbag 15 can play a vertical supporting role for the silicone shock-absorbing pad 2. The shock-absorbing airbag 15 and the silicone shock-absorbing pad 2 play a buffering and shock-absorbing role for the air-permeable cavity plate 3. At the same time, the boost is started. The air compressor 9 allows external air to enter the air intake pipe 16, and the external pressurized air enters the pressurized connecting hose 8 through the air intake pipe 16, and enters the breathable cavity plate 3 through the pressurized connecting hose 8, and the pressurized air is transported to the multiple upper row air holes 4 through the breathable cavity plate 3. The air is discharged from the upper row air holes 4 to the spaced air holes 12 between the two transversely spaced air frame strips 5, and the air is laterally discharged to the lateral exhaust holes 7 inside the two lateral frame strips 6. When the buttocks are in contact with the transversely spaced air frame strips 5, flow ventilation can be achieved on the upper and sides, and the operator can feel more comfortable and breathable when sitting on the transversely spaced air frame strips 5.

[0025] In some embodiments, as shown in the attached Figure 1-3 As shown, a support frame 10 is fixedly connected to one side of the outer wall of the seat support frame 1, and a tractor head 11 for vertically supporting the seat support frame 1 is installed at the bottom end of the support frame 10. The tractor head 11 is fixedly connected to the seat support frame 1 and the support frame 10 respectively, so that the seat support frame 1 and the support frame 10 are fixed at the installation position of the tractor head 11, and the operator's buttocks sit on the upper surface of multiple transversely spaced air-permeable frame strips 5. The tractor head 11 supports the seat support frame 1 and the support frame 10. A backrest 13 is fixedly connected to the top of the support frame 10, and the front and rear sides of the backrest 13 are integrated by injection molding. The seat support frame 1 has an armrest 14, and spaced air holes 12 are provided between two adjacent transverse spaced air frame strips 5, so that the operator can sit on the upper surface of the seat support frame 1 and support his hands through the armrest 14, while the backrest 13 can support the operator's back. The spaced air holes 12 can provide ventilation for the operator, and a shock-absorbing airbag 15 is installed on the inner wall of the seat support frame 1 and below the silicone shock-absorbing pad 2. The breathable cavity plate 3 and the seat support frame 1 are both fixed to the shock-absorbing airbag 15 by hot-melt adhesive, so that the shock-absorbing airbag 15 and the silicone shock-absorbing pad 2 can play a vertical shock-absorbing role on the breathable cavity plate 3, making the ride more comfortable.

[0026] In some embodiments, as shown in the attached Figure 2-4As shown, the input end of the boost air pump 9 is threadedly connected to an intake pipe 16, a spherical filter 17 is rollingly connected to the inner wall of the intake pipe 16 and near the top thereof, a rotating shaft 18 is welded on both sides of the outer wall of the spherical filter 17, the outer wall of the intake pipe 16 is equidistantly distributed in a circular ring and fixedly connected with two bearing rings 19, one end of the rotating shaft 18 passes through the bearing ring 19 and is coaxially connected with a reduction drive motor 20, the top of the intake pipe 16 is equidistantly distributed in a circular ring and has two arc scraping strips 21 for scraping the outer wall of the spherical filter 17, the two arc scraping strips 21 are symmetrically arranged about the spherical filter 17, and the two arc scraping strips 21 are both rotatably connected to the spherical filter 17;

[0027] When the upper structure is in use, the reduction drive motor 20 is started to drive the rotating shaft 18 to rotate inside the bearing ring 19, and the rotating shaft 18 drives the spherical filter 17 to rotate stably inside the intake pipe 16. The spherical filter 17 can filter dust and impurities in the external air. The dust and impurities will accumulate on the outer wall of the spherical filter 17. When the spherical filter 17 rotates, the dust and impurities on the outer wall of the spherical filter 17 are scraped and cleaned by the arc scraping strip 21. The dust and impurities on the outer wall of the spherical filter 17 are difficult to accumulate and clog, thereby ensuring that the intake pipe 16 stably transports external air into the air permeable cavity disk 3.
