[0023] The height of the front support 1 is lower than the height of the rear support 2, thereby causing the conveying plane of the frame body 3 to be in an inclined state. As a preferred scheme, the frame body 3 is inclined upward by 15-45 degrees, and the backfilled material is conveyed from the feeding side to the discharging side.

[0024] One side of the frame body 3 is provided with a driving wheel 41, the other side of the frame body 3 is provided with a driven wheel 42, and the conveying belt 4 is wrapped outside the driving wheel 41 and the driven wheel 42. The discharging side of the frame body 3 is provided with a rear support platform 33 for supporting the driving wheel 41, and the feeding side of the frame body 3 is provided with a front support platform 34 for supporting the driven wheel 42, and the rear support platform 33 and the front support platform 34 mainly lower the axial installation position of the driving wheel 41 and the driven wheel 42, thereby facilitating the smooth conveying of the material on the conveying belt 4.

[0025] In the implementation, the two sides of the passive wheel 42 are installed on the front support 34 through the bearing seat 43, and the end of the front support 34 is provided with an axle adjuster 44 for adjusting the bearing seat 43. According to actual needs, the bearing seat 43 is moved forward through the axle adjuster 44 or is abutted against the outside of the axle adjuster 44 to position the passive wheel 42, so that the conveying belt 4 is in a good tension state.

[0026] As an optional solution, in order to further improve the stability of the frame body 3, the front supports 1 and the rear supports 2 are respectively provided with inclined ribs 11 connected with the bottom of the frame body 3, X ribs 12 are respectively arranged between the two front supports 1 at the feeding end and between the two rear supports 2 at the discharging end, and horizontal ribs 13 are respectively arranged at the bottom of the two front supports 1 and the bottom of the two rear supports 2. The inclined ribs 11, the X ribs 12 and the horizontal ribs 13 can make the front supports 1 and the rear supports 2 form an integrated structure with the frame body 3, so that the stability is higher, and welding is adopted for fixing.

[0027] Rollers 31 for supporting the conveying belt 4 are symmetrically arranged on the two sides of the frame body 3 along the conveying belt 4. The two sides of the conveying belt 4 are supported by the symmetric rollers 3, so that the materials are concentrated in the middle position of the conveying belt 4. In the implementation, the symmetric rollers 31 on the two sides of the frame body 3 at the same conveying position form a group, and each group is arranged in a V shape. In the conveying process, the materials are automatically concentrated in the middle position of the conveying belt 4 due to the support of the V-shaped rollers 31, so as to avoid sliding to the outside.

[0028] Please refer to Figure 2 In the specific arrangement, the top of the frame body 3 is fixed with an angle steel 311 at the mounting position of the roller 31. The angle steel 311 is buckled on the top of the frame body 3, and the two ends are welded and fixed. The two sides of the angle steel 311 are provided with vertical guard plates 312, the top of the guard plate 312 is inwardly bent, so as to cooperate with the V-shaped roller 31. The middle part of the angle steel 311 is provided with a middle plate 313 for supporting the other side of the roller 31. After installation, one side of the roller 31 is rotationally connected with the top of the guard plate 312, and the other side of the roller 31 is rotationally connected with the middle plate 313.

[0029] The discharging bin 5 is mounted on the feeding side of the frame body 3 through a support rod 52. The support rod 52 is provided with a plurality of steel bars in the implementation. The opening of the discharging bin 5 faces the material conveying direction of the conveying belt 4. The discharging bin 5 is in a suspended state under the support of the support rod 52. The bottom of the discharging bin 5 can be provided with a chute. When the stone materials are conveyed, the materials directly contact the bottom conveying belt 4 and are conveyed forward under the driving of the conveying belt 4. The discharging bin 5 can block the materials placed at the rear side and the two sides, so as to prevent the materials from falling off.

[0030] As a preferred scheme, the inside of the discharge bin 5 is paved with a layer of rubber pad 51, and the rubber pad 51 is fixed with the discharge bin 5 through screws, so as to prevent the material such as stone from damaging the discharge bin 5. The rubber pad 51 mainly protects the rear side and both sides of the discharge bin 5. For the bottom of the discharge bin 5, only the part without the chute is protected, so as to avoid affecting the conveying of the material.

[0031] In order to limit the two sides of the material conveying, the above scheme is provided with a stop roller 32 symmetrically installed on both sides of the frame body 3, for limiting and limiting the left and right shaking of the conveying belt 4. Please refer to Figure 3 , the top of the frame body 3 is fixed with a plug rod 321 through a pad 322, and the stop roller 32 is inserted into the top of the plug rod 321 and is rotationally connected with the plug rod 321. By arranging the stop roller 32, the conveying belt 4 can be blocked and corrected, so as to always be in the middle of the frame body 3, that is, always be between a group of V-shaped rollers 31, so as to facilitate the smooth conveying of the material.

[0032] In summary, the frame body 3 is inclined and arranged, and the two ends thereof are arranged beyond the wrong lane of the water tunnel, so as to "bridge" the position where the wrong lane exists, the material is conveyed by the conveying belt 4, and the material is concentrated in the middle of the conveying belt 4 by the V-shaped roller 31. This way of conveying the material by the conveying belt 4 and smoothly conveying the material to the wrong lane can reduce the transportation cost of manual labor during the construction of the water tunnel and improve the work efficiency.

[0033] The above specific embodiments further illustrate the purpose, technical scheme and beneficial effects of the present application. It should be understood that the above description is only a specific embodiment of the present application, and is not used to limit the protection scope of the present application.
