[0027] The following details the embodiments of the present utility model. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals always represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0028] The following disclosure provides many different embodiments or examples for implementing different solutions of the present utility model.

[0029] Refer to Figures 1 to 4 As shown, in an embodiment of the present utility model, a tail return device for a belt conveyor includes a belt conveyor 1, a tail housing 2, and a spring auger 3. The tail housing 2 includes a frame 21 through which the belt conveyor 1 passes and a tail cover 22 covering the input end of the belt conveyor 1. The frame 21 is docked with the tail cover 22;

[0030] The tail cover 22 includes an arc plate 221, a guide plate 222, and two side plates 223. The arc plate 221 protrudes outward. The guide plate 222 is located below the belt conveyor 1 and slopes downward in a direction close to the arc plate 221. The lower end of the guide plate 222 is connected to the lower end of the arc plate 221; the two side plates 223 are respectively arranged at both ends of the arc plate 221 along the width direction of the belt conveyor 1, and the side plates 223 connect the arc plate 221 and the guide plate 222; an aggregate chamber is formed between the arc plate 221 and the guide plate 222;

[0031] The input end of the spring auger 3 is connected to the aggregate chamber, and the output end of the spring auger 3 is connected to the top of the frame 21;

[0032] At the tail of the belt conveyor 1, a tail housing 2 is arranged. The scattered materials that fall from the belt conveyor 1 will accumulate at the bottom of the frame 21, and then through the transportation of the belt conveyor 1, the fallen scattered materials are pushed into the aggregate chamber. Relying on the operation of the spring auger 3, the scattered materials in the aggregate chamber are transported to the top of the frame 21, and the scattered materials can fall back onto the belt conveyor 1 again for continuous transportation. In this way, the scattered materials can be recycled, waste can be reduced, and at the same time, there is no need to clean frequently, reducing the burden on maintenance personnel.

[0033] In this embodiment, the spring auger 3 includes a spiral spring 31, a motor 32 that drives the spiral spring 31 to rotate, and a hose 33. The spiral spring 31 passes through the hose 33 and is connected to the aggregate chamber;

[0034] A return material port is provided at the top of the frame 21, and a protective box 34 is covered on the return material port. The motor 32 is fixed on the protective box 34;

[0035] A rotating shaft 224 is provided on one side plate 223, and a support pipe 225 is provided on the other side plate 223. The hose 33 connects the support pipe 225 and the protective box 34, and the spiral spring 31 passes through the support pipe 225 and is connected to the rotating shaft 224;

[0036] Therefore, the spiral spring 31 passes through the aggregate chamber along the width direction of the belt conveyor 1. The spiral spring 31 agitates in the aggregate chamber to bring the scattered materials into the hose 33, and then gradually transports them into the protective box 34, and is discharged onto the belt conveyor 1 through the return material port.

[0037] In this embodiment, the shapes of the arc-shaped plate 221 and the guide plate 222 make the aggregate chamber a structure that is thick at the top and thin at the bottom, which can effectively accumulate the scattered materials, allowing the scattered materials to continuously fall to the connection between the arc-shaped plate 221 and the guide plate 222. Coupled with the fact that the lower end of the guide plate 222 is connected to the lower end of the arc-shaped plate 221 with an arc transition connection, therefore, the connection between the guide plate 222 and the arc-shaped plate 221 is also arc-shaped, and the spiral spring 31 will contact the connection between the guide plate 222 and the arc-shaped plate 221, and can transport the scattered materials at the lowest position away.

[0038] In this embodiment, the frame 21 includes a bottom plate 211, a top plate 212, and two side wall plates 213. The two side wall plates 213 are located at both ends of the bottom plate 211 along the width direction of the belt conveyor 1, and the side wall plates 213 connect the bottom plate 211 and the top plate 212;

[0039] The upper end of the arc-shaped plate 221 is connected to the top plate 212, the side plate 223 is connected to the side wall plate 213, and the upper end of the guide plate 222 is connected to the bottom plate 211, so that the frame 21 is docked with the tail cover 22. The scattered materials on the belt conveyor 1 will fall to the bottom, and when the belt conveyor 1 transports, the scattered materials on the bottom plate 211 can be pushed to the guide plate 222 and enter the aggregate chamber; even a scraping blade can be provided on the belt of the belt conveyor 1. During the operation of the belt conveyor 1, the scraping blade can intermittently scrape the scattered materials on the bottom plate 211.

[0040] In this embodiment, the top surface of the bottom plate 211 is higher than the upper end of the guide plate 222, ensuring that the bulk materials on the bottom plate 211 can fall into the aggregate chamber.

[0041] In this embodiment, two guide grooves 2111 are provided at one end of the bottom plate 211 close to the guide plate 222. The two guide grooves 2111 are located at both ends of the bottom plate 211 along the width direction of the belt conveyor 1, and the bottom of the guide groove 2111 slopes downward in the direction close to the guide plate 222;

[0042] The bulk materials dropped by the belt conveyor 1 will basically fall on both sides of its conveying direction. Therefore, the bulk materials are more likely to be docked at both ends of the bottom plate 211 along the width direction of the belt conveyor 1. The provided guide grooves 2111 can accelerate the discharging speed and enable the bulk materials to fall into the aggregate chamber as soon as possible.

[0043] In this embodiment, an observation window 226 is provided on the arc-shaped plate 221. By opening the observation window 226, the operation condition of the belt conveyor 1 can be observed.

[0044] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
