[0033] For example, refer to Figure 1 and Figure 3 Both the damping plate seat 11 and the base plate 12 are flat and identical in shape, with the outline edge of the damping plate seat 11 and the outline edge of the base plate 12 vertically aligned. The bottom end of the damping component 2 is fixed to the base plate 12, and the top end of the damping component 2 extends vertically upward and is fixed to the bottom surface of the damping plate seat 11. There are multiple damping components 2. Elastic rubber covers 6 correspond one-to-one with each damping component 2.

The three groups of damping components 2 are spaced apart along the length of the base plate 12, and each damping component 2 is covered with an elastic rubber cover 6. The bottom end of the elastic rubber cover 6 is fixedly connected to and sealed with the base plate 12, and the top end of the elastic rubber cover 6 is fixedly connected to and sealed with the shock absorber plate seat 11. The exhaust channel is, for example, a hole on the side wall of the elastic rubber cover 6. A one-way exhaust pipe 24 can also be fixedly connected in the aforementioned hole to ensure the air pressure inside the elastic rubber cover 6 is stable when the elastic rubber cover 6 is compressed along with the shock absorber 2. When the elastic rubber cover 6 returns to its original shape, the air pressure inside the elastic rubber cover 6 is balanced through the air intake channel 3.

[0034] In this embodiment, the mining equipment is supported by the shock-absorbing plate seat 11, and the shock-absorbing component 2 is used to absorb the vibration generated by the outside world, reduce the impact of the external vibration on the mining equipment, and maintain the covering posture of the shock-absorbing component 2 while deforming after being subjected to external vibration, reduce the possibility of external debris adhering to the shock-absorbing component 2, and extend the service life of the shock-absorbing component 2.

[0036] For example, refer to Figure 2 and Figure 3 The hollow cylindrical component 23 has an open bottom end and is fixedly connected to the base plate 12. The top end of the hollow cylindrical component 23 is closed and extends upward inside the elastic rubber cover 6. The bottom end of the buffer spring 22 is fixedly connected to the base plate 12 surrounding the bottom opening of the hollow cylindrical component 23, and the top end of the buffer spring 22 extends vertically upward inside the hollow cylindrical component 23. The bottom end of the sliding column 21 penetrates the hollow cylindrical component 23 vertically and extends into the interior of the hollow cylindrical component 23. The bottom end of the sliding column 21 extending into the interior of the hollow cylindrical component 23 is coaxially fixed with the buffer spring 22, and the top end of the sliding column 21 extends vertically upward to the bottom surface of the shock absorber seat 11 and is fixedly connected to the shock absorber seat 11.

[0037] In this embodiment, the side wall of the buffer spring 22 can abut against the inner wall of the hollow cylinder 23 to reduce the possibility of the buffer spring 22 tilting when compressed and extend the service life of the buffer spring 22.

[0040] For example, refer to Figure 2 and Figure 3The first horizontal tube 33 and the second horizontal tube 31 are both fixed horizontally on the base plate 12, and are perpendicular to each other. Each set of shock-absorbing components 2 has a first horizontal tube 33 on one side. One end of the flexible air tube 34 is fixedly connected to the side wall of the elastic rubber cover 6, and the other end extends downward and is fixedly connected to the first horizontal tube 33. The second horizontal tube 31 runs through three horizontal tubes 31 along the length of the base plate 12, and is located at the middle position of the length of the first horizontal tube 33. The fan 32 is fixedly connected at the middle position of the length of the second horizontal tube 31.

The top surface of the second horizontal tube 31 is open at the middle of its length and is fixed with a protruding ring 311 that is adapted to the insertion ring 51. Multiple magnets 312 are fixed at intervals along the circumference at the top of the protruding ring 311. The magnets 312 are built into the solid structure at the top of the protruding ring 311. Under the action of gravity and magnetic force, the insertion ring 51 can be inserted into the protruding ring 311, so that the air filter cartridge 5 and the second horizontal tube 31 are inserted vertically and snapped in other directions, thus realizing the connection between the air filter cartridge 5 and the second horizontal tube 31.

[0044] In this embodiment, a vertically arranged connecting spring 53 is fixed on the air filter cartridge 5. The bottom end of the connecting spring 53 is fixedly connected to the air filter cartridge 5, and the top end of the connecting spring 53 extends upward and is fixedly connected to a handle 52.

[0045] In an exemplary embodiment of this disclosure, reference is made to Figure 1 and Figure 5 The damping plate seat 11 is fixed with a chute frame 4 for accommodating mining equipment.

The sliding frames 4 are horizontally fixed to the top surface of the damping plate seat 11. A threaded rod 43 is threadedly connected to the sliding frame 4 and runs horizontally through the sliding frame 4. The two ends of the threaded rod 43 are located inside and outside the sliding frame 4, respectively. The end of the threaded rod 43 located inside the sliding frame 4 is rotatably connected to a sliding clamping block 41 that matches the internal contour of the sliding frame 4. By rotating the threaded rod 43, the sliding clamping block 41 can be driven to slide inside the sliding frame 4, thereby clamping the machine feet of the mining equipment to achieve fixation.

[0047] In this embodiment, the threaded rod 43 and the sliding clamping block 41 can be connected by a turntable or other structures. Each slide frame 4 has two threaded rods 43, which are distributed opposite each other at both ends of the slide frame 4. Rubber plates 42 are fixedly connected to the side walls of the sliding clamping blocks 41 that are rotatably connected to the two threaded rods 43, respectively, to enhance the clamping effect on the mining equipment and reduce the possibility of damage to the mining equipment during the clamping process.
