[0017] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0019] like Figures 1-3As shown, a guide trough for a belt conveyor is disclosed. The belt conveyor includes an idler assembly and a conveyor belt 1. The idler assembly includes an idler bracket 2. A bottom roller 3 is rotatably connected to the middle horizontal section of the idler bracket 2, and side rollers 4 are rotatably connected to the two inclined sections on both sides of the idler bracket 2. The conveyor belt 1 is disposed on top of the bottom roller 3 and the side rollers 4. The guide trough includes a base frame 5. The idler assembly is mounted above the base frame. Fixed side plates 6 are installed on both sides of the base frame 5. Nuts 7 are fixedly installed on the fixed side plates 6. A threaded push rod 8 passes through the fixed side plates 6 and the nuts 7. The threaded push rod 8 is threadedly connected to the nuts 7. A push plate 9 is fixedly connected to the inner side of the threaded push rod 8. A supporting horizontal plate 10 is fixedly connected to the inner side of the fixed side plate 6. A guide plate 11 is hinged to the inner side of the supporting horizontal plate 10. The push plate 9 abuts against the outer side of the guide plate 11.

[0020] Specifically, rotating the threaded push rod 8 can drive the push plate 9 to translate, push the guide plate 11 to rotate, change the included angle of the guide plate 11, and make the falling material concentrate and fall towards the middle of the roller group.

[0021] The top of the supporting horizontal plate 10 is provided with an arc-shaped top plate 12, and connecting plates 13 are fixedly installed at the front and rear of the arc-shaped top plate 12.

[0022] Specifically, the arc-shaped top plate 12 guides the falling material onto the conveyor belt 1 to prevent dust from being generated and causing pollution. The connecting plate 13 is used in conjunction with bolts to connect multiple arc-shaped top plates 12.

[0023] A sealing plate 14 is provided between the arc-shaped top plate 12 and the fixed side plate 6. A plurality of limiting screw holes are equally spaced on the supporting horizontal plate 10 and the sealing plate 14. A locking screw 15 is inserted through the limiting screw hole and is threadedly connected to the supporting horizontal plate 10 and the sealing plate 14.

[0024] Specifically, the sealing plate 14 is used to prevent dust from overflowing when the belt conveyor vibrates during operation, which would cause the gap between the arc-shaped top plate 12 and the fixed side plate 6 to widen.

[0025] A flip cover 16 is provided on the arc-shaped top plate 12, and the flip cover 16 is hinged to the arc-shaped top plate 12.

[0026] Specifically, open the flip cover 16 to connect the discharge port to the guide chute and add material to the conveyor belt 1.

[0027] An anti-overflow plate 17 is fixedly installed in the middle of the inner side of the fixed side plate 6. A wear-resistant pad 18 is fixedly connected to the inner side of the anti-overflow plate 17, and the wear-resistant pad 18 abuts against the bottom of the conveyor belt 1.

[0028] Specifically, the overflow plate 17 prevents excessive material from overflowing and contaminating the belt conveyor, while the wear-resistant pad 18 is made of nylon to reduce wear on the conveyor belt 1.

[0029] A throttle 19 is fixedly installed on the outer side of the threaded push rod 8.

[0030] A dust curtain 20 is fixedly connected to the connecting plate 13 on the outer side of the arc-shaped top plate 12 located on the feeding side.

[0031] When using this utility model, open the flip cover 16, rotate the handle 19 to adjust the opening angle of the guide plate 11, so that the falling material is concentrated and falls into the middle of the idler roller group. Turn on the belt conveyor and put the material into the conveyor belt 1 through the opening of the flip cover 16 for conveying. The base frame 5, fixed side plate 6, arc-shaped top plate 12, anti-overflow plate 17, and dust curtain 20 form a guide trough structure to prevent dust from overflowing.

[0032] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
