[0027] The present invention provides a technical solution:

[0028] Embodiment 1

[0029] Combined with Figures 1 to 3 , a sealing device for an environment-friendly asphalt supply bin, including a supply bin 3, a feeding port 31 fixedly connected to the top of the supply bin 3, a discharge pipe 32 fixedly connected to the bottom right of the supply bin 3, a fixing mechanism 1 arranged on the top of the supply bin 3, and a sealing mechanism 2 sleeved outside the feeding port 31.

[0030] The fixing mechanism 1 includes a support assembly 11, an adjustment assembly 12, a pressing-down assembly 13, and a limiting assembly 14. The support assembly 11 is arranged on the top of the supply bin 3, the adjustment assembly 12 is arranged inside the top of the support assembly 11, the pressing-down assembly 13 is arranged at the bottom of the adjustment assembly 12, and the limiting assembly 14 is arranged on the front and rear sides of the top of the pressing-down assembly 13.

[0031] The support assembly 11 includes a fixing frame 1101 which is fixedly connected to the top of the feeding bin 3 at positions on both sides of the feeding port 31. The top of the fixing frame 1101 is fixedly connected with a top plate 1102. The adjusting assembly 12 includes a threaded cylinder 1201 which is fixedly connected to the inside of the top of the top plate 1102.

[0032] Furthermore: The staff only needs to rotate the torsion disc 1203 to control the synchronous up and down movement of the pressing block 1304 and the positioning latch 2203. When the bottom of the pressing block 1304 contacts the top of the sealing cover 2101, the positioning latch 2203 is snapped into the fixing cylinder 2202 to complete the positioning of the sealing cover 2101, so that the sealing cover 2101 can be pressed down to the limit, and the sealing ring 2102 is deformed by force to fully fill the space where the feeding port 31 contacts the sealing cover 2101, increasing the sealing performance of the feeding port 31 after the sealing cover 2101 is closed, preventing the asphalt from leaking. At the same time, the staff only needs to rotate the torsion disc 1203 to control the synchronous upward movement of the pressing block 1304 and the positioning latch 2203 to release the positioning of the sealing cover 2101, facilitating the staff to seal or open / close the feeding port 31, with simple operation and convenient for the staff to use.

[0033] Embodiment 2

[0034] Refer to Figures 1 to 5 and, on the basis of Embodiment 1, it is further obtained that the sealing mechanism 2 includes a sealing assembly 21, a positioning assembly 22 and a reinforcement assembly 23. The sealing assembly 21 is sleeved outside the feeding port 31. The positioning assembly 22 is arranged on both sides of the sealing assembly 21. The reinforcement assembly 23 is arranged outside the positioning assembly 22.

[0035] The sealing assembly 21 includes a sealing cover 2101, the sealing cover 2101 is sleeved outside the feeding port 31, a sealing ring 2102 is fixedly connected to the inner top of the sealing cover 2101, the bottom of the sealing ring 2102 is in contact with the top of the feeding port 31, a sealing sleeve ring 2103 is fixedly connected to the bottom of the sealing ring 2102, and the outer ring of the sealing sleeve ring 2103 is in contact with the inner ring of the feeding port 31. The positioning assembly 22 includes a convex frame 2201, the convex frame 2201 is fixedly connected to the front and rear sides of the sealing cover 2101, a fixed cylinder 2202 is fixedly connected to the outside of the convex frame 2201, a positioning rod 2203 is clamped in the fixed cylinder 2202, and the positioning rod 2203 is fixedly connected to the bottom of the fixing plate 1302. The reinforcement assembly 23 includes reinforcement fins 2301, the reinforcement fins 2301 are fixedly connected to the left and right sides of the convex frame 2201, the reinforcement fins 2301 are fixedly connected to the front and rear sides of the sealing cover 2101, a reinforcing plate 2302 is arranged below the reinforcement fins 2301, the reinforcing plate 2302 is fixedly connected to the bottom of the convex frame 2201, the reinforcing plate 2302 is fixedly connected to the front and rear sides of the sealing cover 2101, the reinforcing plate 2302 is fixedly connected to the inner side of the outer ring of the fixed cylinder 2202, and connecting arc plates 2303 are fixedly connected to the left and right sides of the reinforcing plate 2302, and the connecting arc plates 2303 are fixedly connected to the bottom of the reinforcement fins 2301.

[0036] Furthermore: The settings of the sealing ring 2102 and the sealing sleeve ring 2103 completely fill the contact surface between the feeding port 31 and the sealing cover 2101, increasing the sealing performance of the feeding port 31 after the sealing cover 2101 is closed. At the same time, the setting of the reinforcement assembly 23 reinforces the positioning assembly 22, increasing the structural strength of the convex frame 2201 and the fixed cylinder 2202, so that the fixed cylinder 2202 will not deform due to the downward force exerted by the positioning rod 2203, and improving the downward pressure exerted by the positioning rod 2203 on the sealing cover 2101.

[0037] During the actual operation process, when this device is in use and it is necessary to seal the feeding port 31, the staff first rotate the torsion disk 1203. The rotation of the torsion disk 1203 drives the rotation of the threaded rod 1202. The threaded rod 1202 rotates and moves upward within the inner ring of the threaded barrel 1201. The upward movement of the threaded rod 1202 drives the pressing block 1304 and the positioning latch 2203 to move upward through the fixing plate 1302 until the top of the fixing plate 1302 is in contact with the bottom of the top plate 1102. After that, the staff can sleeve the sealing cover 2101 outside the feeding port 31. Then the staff rotate the torsion disk 1203 in the reverse direction. As known above, the reverse rotation of the torsion disk 1203 drives the pressing block 1304 and the positioning latch 2203 to move downward. The downward movement of the pressing block 1304 contacts the top of the sealing cover 2101 and applies a downward pressure to the sealing cover 2101. The downward movement of the positioning latch 2203 is clamped in the fixed cylinder 2202 and applies a downward pressure to the sealing cover 2101 through the convex frame 2201 until the torsion disk 1203 cannot rotate and the pressing block 1304 and the positioning latch 2203 move downward to the limit. At this time, the closing and sealing process of the feeding port 31 is completed.
