The feed pipe 1 is provided with a stepped platform 3, the stepped platform 3 is provided with a sealing plug 4, a sealing ring 5 is provided between the sealing plug 4 and the stepped platform 3, a compression groove 6 is provided on the cover plate 2, a compression spring 7 is provided on the compression groove 6, a compression plate 8 is provided on the compression spring 7, a connecting device is provided between the cover plate 2 and the feed pipe 1, the connecting device includes a connecting block 9, a connecting rod 10 is provided on the cover plate 2, a connecting groove 11 is provided on the connecting block 9, a clamping groove 12 is provided in the circumference of the connecting groove 11, a clamping spring 13 and a clamping block 14 are provided in the clamping groove 12, a clamping hole 15 cooperating with the clamping block 14 is provided on the connecting rod 10, a compression pad 22 is provided between the cover plate 2 and the feed pipe 1, a boss 23 is provided on the cover plate 2, a groove 24 cooperating with the boss 23 is provided on the compression pad 22, and an anti-aging layer 25 is provided on the sealing plug 4.

[0028] In this embodiment, when the feed pipe 1 and the cover plate 2 are connected and installed, the sealing plug 4 is placed on the stepped platform 3, and the sealing ring 5 is used to improve the connection sealing between the sealing plug 4 and the stepped platform 3. The cover plate 2 is buckled on the feed pipe 1, and the compression plate 8 is pressed downward by the compression spring 7 in the compression groove 6. The sealing plug 4 is buckled on the stepped platform 3 through the compression plate 8, thereby improving the sealing of the internal connection between the cover plate 2 and the feed pipe 1. The anti-aging layer 25 can be made of polyurethane coating, which has good adhesion, wear resistance and weather resistance. At the same time, a compression pad 22 is installed on the cover plate 2 through the cooperation of the boss 23 and the groove 24. When the cover plate 2 is connected to the feed pipe 1, the bottom of the compression pad 22 is pressed on the feed pipe 1, thereby improving the sealing of the external connection between the feed pipe 1 and the cover plate 2.

[0029] See also Figure 4-Figure 5 As an embodiment of the connecting device: a reset sleeve 16 is provided on the connecting groove 11, the bottom of the reset sleeve 16 contacts the clamping block 14 with an inclined surface, a reset plate 17 is provided on the reset sleeve 16, a reset rod 18 is slidably provided between the reset plate 17 and the connecting block 9, a reset spring 19 is provided between the reset plate 17 and the connecting block 9, and a connecting spring 20 and a connecting plate 21 are provided in the connecting groove 11.

[0030] More specifically, when connecting the cover plate 2 and the feed pipe 1, the connecting rod 10 is extended into the connecting groove 11 of the connecting block 9, and the connecting plate 21 and the connecting spring 20 are squeezed downward. First, the connecting rod 10 squeezes the clamping block 14 and the clamping spring 13 outward. When the clamping block 14 is aligned with the clamping hole 15, the clamping block 14 is extended into the clamping hole 15 under the elastic force of the clamping spring 13, and the position of the connecting rod 10 is fixed. The elastic force of the connecting plate 21 and the connecting spring 20 improves the clamping of the clamping block 14 and the clamping hole 15. The connection tightness is improved, thereby improving the connection tightness of the cover plate 2 and the feed pipe 1. When the cover plate 2 is removed, the reset sleeve 16 and the reset plate 17 move downward to compress the reset spring 19 under the limiting action of the reset rod 18. When the reset sleeve 16 moves downward, the clamping block 14 is squeezed and recovered into the clamping groove 12, so that the connecting rod 10 pops up upward under the elastic force of the connecting plate 21 and the connecting spring 20, which is convenient for removing the cover plate 2. The reset plate 17 and the reset sleeve 16 are reset under the elastic force of the reset spring 19, which is convenient for removing the cover plate 2.

[0031] In summary, when the overall equipment is in use or running: when the feed pipe 1 and the cover plate 2 are connected and installed, the sealing plug 4 is placed on the stepped platform 3, and the sealing ring 5 is used to improve the connection sealing between the sealing plug 4 and the stepped platform 3, and the cover plate 2 is buckled on the feed pipe 1, and the compression plate 8 is pressed downward by the compression spring 7 in the compression groove 6, and the sealing plug 4 is buckled on the stepped platform 3 through the compression plate 8, thereby improving the sealing of the internal connection between the cover plate 2 and the feed pipe 1. The anti-aging layer 25 can be made of polyurethane coating, which has good adhesion, wear resistance and weather resistance. At the same time, a compression pad 22 is installed on the cover plate 2 through the cooperation of the boss 23 and the groove 24. When the cover plate 2 is connected to the feed pipe 1, the bottom of the compression pad 22 is pressed on the feed pipe 1, thereby improving the sealing of the external connection between the feed pipe 1 and the cover plate 2.

[0032] When connecting the cover plate 2 and the feed pipe 1, the connecting rod 10 is extended into the connecting groove 11 of the connecting block 9, and the connecting plate 21 and the connecting spring 20 are squeezed downward. First, the connecting rod 10 squeezes the clamping block 14 and the clamping spring 13 outward. When the clamping block 14 is aligned with the clamping hole 15, the clamping block 14 is extended into the clamping hole 15 under the elastic force of the clamping spring 13, and the position of the connecting rod 10 is fixed. The elastic force of the connecting plate 21 and the connecting spring 20 improves the clamping tightness of the clamping block 14 and the clamping hole 15. The tightness is improved, thereby improving the tightness of the connection between the cover plate 2 and the feed pipe 1. When the cover plate 2 is removed, the reset sleeve 16 and the reset plate 17 move downward under the limiting action of the reset rod 18 to compress the reset spring 19. When the reset sleeve 16 moves downward, the clamping block 14 is squeezed and recovered into the clamping groove 12, so that the connecting rod 10 pops up upward under the elastic force of the connecting plate 21 and the connecting spring 20, which is convenient for removing the cover plate 2. The reset plate 17 and the reset sleeve 16 are reset under the elastic force of the reset spring 19, which is convenient for removing the cover plate 2.
