During pouring, a pouring port is generally reserved on the prestressed track plate, and the concrete enters between the track plate and the base through the hopper at the pouring port.
[0003] In the existing construction technology, there is usually a gap between the discharge port of the hopper and the casting port. Part of the outside air will flow into the space between the track plate and the base plate as the concrete is poured, resulting in bubbles inside the self-compacting concrete, affecting the stability of the filling layer concrete. In addition, the height and size of the pouring port of the hopper in the prior art are not convenient to adjust, and it is not easy to achieve overall push-type pouring. CN201627123U discloses a ballastless track switch slab concrete pouring hopper, which controls the opening and closing of the baffle by a hydraulic cylinder to pour concrete. On the one hand, a hydraulic cylinder needs to be set up in this scheme, which is costly. On the other hand, the height of the pouring port cannot be adjusted, and there is a large gap between the discharge port and the switch slab casting port.

[0026] Embodiment 1
[0027] In a typical implementation of the present invention, reference is made to Figure 1-Figure 3 As shown, a hopper for pouring a self-compacting concrete filling layer of a slab ballastless track includes a silo 4, which is supported by a support column 1. A height adjustment component is provided at the bottom of the support column 1. A guide pipe 6 is provided at the bottom of the silo 4. A guide adjustment plate 7 is rotatably provided on the guide pipe 6. The discharge speed can be adjusted by rotating the guide adjustment plate 7. A retaining ring 61 is provided on the periphery of the guide pipe 6. By setting the height adjustment component, the height of the guide pipe 6 can be adjusted so that the guide pipe 6 is inserted into the pouring port of the ballast plate, and the pouring port of the ballast plate is blocked by the retaining ring 61. In this way, during the pouring process, the sealing between the discharge port and the pouring port of the ballast plate can be maintained, effectively preventing the entry of outside air.
[0028] like Figure 1 As shown, the top of the silo 4 is cylindrical and the bottom is funnel-shaped, and a material guide pipe 6 is provided at the center of the bottom end of the silo funnel section. The silo 4 is supported by four support columns 1 on the periphery, and a height adjustment component is provided at the bottom end of the support column 1 to adjust the height of the material guide pipe 6.
[0029] The four support columns 1 are connected as a whole by a fixing ring 3, which is located at the bottom of the cylindrical section of the silo. The shape of the fixing ring 3 is the same as the cross-section of the silo, and the fixing ring 3 is fixedly welded to the silo. The support columns 1 are connected by a crossbeam 2 near the bottom to improve strength.
[0030] The top of the silo 4 is connected to a silo edge ring plate 5, and a plurality of lifting rings 51 are fixedly connected to the silo edge ring plate 5 for easy lifting. The outer side of the support column 1 is fixedly connected to a handle bar 8, through which the position of the hopper can be adjusted during lifting.
[0031] like Figure 2 As shown, the height adjustment assembly includes a bottom plate 11 disposed at the bottom end of the support column 1, and a through hole is provided on the bottom plate 11, and a screw rod 13 is slidably connected in the through hole. The screw rod is parallel to the support column and is disposed on the inner side of the support column 1. The cross section of the support column is preferably L-shaped, and two groups of nuts 12 are threadedly connected on the screw rod 13, and each group of nuts is provided with at least two. The two groups of nuts 12 are respectively located above and below the bottom plate 11 and support the bottom plate 11. The bottom end of the screw rod 13 is fixed with a pad 14 for anti-slip. By rotating the nut 12, the relative position of the screw rod 13 and the support column 1 can be adjusted. After adjusting the position, tighten the nut to adjust the height of the guide tube 6.
[0032] like Figure 1 and Figure 3 As shown, a retaining ring 61 is arranged around the guide tube, and an opening 63 is arranged horizontally near the top of the side wall of the guide tube 6. The retaining ring is a circular ring structure, and the retaining ring 61 is located below the opening 63. The opening 63 is a semicircular opening, and the opening 63 is slidably matched with the guide adjustment plate 7.
[0033] Specifically, the outer side of the material guide tube 6 is rotatably connected with the material guide adjustment plate 7, and a fixed block 62 is provided on the outer side of the side wall of the material guide tube. The material guide adjustment plate 7 includes a circular baffle, and a rotating block is provided at one end of the baffle 71. The fixed block 62 is relative to the hinge seat, and a through hole is provided on the rotating block.

The fixed block 62 is arranged near one end of the opening, and an extension rod 72 is provided at the other end of the baffle 71. The setting of the extension rod 72 facilitates the rotation of the baffle 71. Rotating the material guide adjustment plate 7 can change the relative position of the material guide adjustment plate 7 and the opening 63. When the baffle 71 rotates with the rotating block, it can enter the material guide tube 6 from the opening 63. The baffle 71 can completely block, partially block, or completely open the material guide tube 6 through the baffle 71, so that the speed of material guiding by the material guide tube 6 can be controlled.
[0034] When this embodiment is in use, the height of the support column 1 can be adjusted by the height adjustment component, thereby changing the height of the guide pipe 6, so that the bottom end of the guide pipe 6 can be inserted into the roadbed plate pouring port, and the roadbed plate pouring port is blocked by the retaining ring 61, so that during the pouring process, the sealing between the discharge port and the roadbed plate pouring port can be maintained, effectively preventing the entry of external air. In addition, the height and discharge speed of the guide pipe 6 can be freely adjusted.
[0035] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes.
