DETAILED DESCRIPTION
[0025] In order for those skilled in the art to more clearly and clearly understand the technical scheme of the utility model, the utility model will be further described in detail below in conjunction with embodiments and drawings, but the embodiments of the utility model are not limited thereto.
[0026] As Figures 1-6 shown, the underground material conveying device provided by the embodiment comprises a plurality of detachably connected discharge pipes 1, the top of each discharge pipe 1 is connected with a first flange 2, the bottom of each discharge pipe 1 is connected with a second flange 3, a dredging hole 4 is formed in the outer wall of each discharge pipe 1 close to the second flange 3, and a sealing cavity 5 is arranged on the top of the second flange 3 of each discharge pipe 1. Through the arrangement of the dredging hole 4 and the sealing cavity 5, when blockage occurs, water is added in the sealing cavity 5 for soaking, so as to increase lubricity and fluidity and play a dredging role. If the blockage is serious, the concrete is pushed from the dredging hole 4 by using a crowbar or other tools while the water is soaked, so as to dredge. The device is simple and practical, avoids manual external knocking of the discharge pipe, can effectively reduce the safety risk, and ensures the safety of workers.
[0027] In the embodiment, as Figure 3 , Figure 4 and Figure 5 shown, a first sealing ring 6 is connected between the two adjacent discharge pipes 1, a sealing cover 7 is detachably arranged on the outer side of each discharge pipe 1 on the top of the sealing cavity 5, the sealing cavity 5 and the sealing cover 7 are connected by bolts, a second sealing ring 8 is arranged between the sealing cavity 5 and the sealing cover 7, the sealing cover 7 is a ring-shaped sealing cover, a third sealing ring 9 is connected between the inner wall of the sealing cover 7 and the outer wall of each discharge pipe 1, an outer edge 10 is connected to the top of the sealing cavity 5, a first connecting hole 11 is formed in the outer edge 10 and matched with the bolt, and a second connecting hole 12 is formed in the sealing cover 7 and matched with the first connecting hole 11. Through the first sealing ring 6, the second sealing ring 8 and the third sealing ring 9, the function of preventing leakage can be achieved. Through the arrangement of the sealing cover 7, the overflow of the concrete from the sealing cavity 5 can be prevented.
