Abstract
Description
Technical Field
[0001] This utility model relates to the field of aggregate conveying technology, specifically to a self-cleaning aggregate conveyor. Background Technology
[0002] Aggregate conveyor belts are used in concrete mixing plants to transport concrete aggregates such as sand and gravel to the concrete mixing equipment for mixing. On the return journey, sand and fine stones easily adhere to the conveyor belt and fall off during the return trip. Because the conveyor line is long, the area of scattering is large, making manual cleaning difficult. Currently, most methods involve installing scrapers tangentially against the aggregate conveyor belt. The conveyor belt's power scrapes off the sand and fine stones adhering to the belt surface. However, even after the scrapers clean the aggregate conveyor belt, dust and fine sand still remain, which are difficult to remove. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a self-cleaning aggregate conveyor, which solves the problem of difficult cleaning of sand and fine stones adhering to the aggregate conveyor belt.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning aggregate conveyor, comprising a soft-bristled roller brush, a dust-blowing mechanism, and a cloth roller arranged sequentially along the conveying direction below the top discharge end of the aggregate conveyor belt. The soft-bristled roller brush is arranged parallel to the aggregate conveyor belt and is rotatably connected to the conveyor belt frame, and is driven to rotate by a drive motor fixed to the conveyor belt frame. The brush end of the soft-bristled roller brush extends to the outer surface of the aggregate conveyor belt below and contacts and rotates. The dust-blowing mechanism is fixed to the conveyor belt frame along the parallel to the aggregate conveyor belt. The dust-blowing mechanism includes an air guide pipe and a fan. The air guide pipe is provided with air distribution holes, and the air guide pipe is supplied with air by the fan. The air distribution holes of the air guide pipe blow air towards the outer side of the aggregate conveyor belt. The cloth roller is fixed to the conveyor belt frame along the parallel to the aggregate conveyor belt. The aggregate conveyor belt contacts the roller surface of the cloth roller, and the cloth roller is located outside the aggregate conveyor belt.
[0005] Preferably, guide roller one and guide roller two are respectively provided on both sides of the cloth roller on the conveyor belt frame, and guide roller one and guide roller two are located on the inner side of the belt surface below the aggregate conveyor belt. The aggregate conveyor belt passing between the roller surfaces of guide roller one and guide roller two is pushed upward by the cloth roller.
[0006] Preferably, the air distribution holes on the air guide duct extend along the length of the air guide duct, and the air distribution holes face the direction of the soft brush.
[0007] Preferably, the air guide pipe is located behind the first guide roller, and the air guide pipe blows air through the air distribution hole along the inclined angle direction of the front belt surface guided by the first guide roller.
[0008] Preferably, the soft-bristle roller brush has soft polyester fiber bristles.
[0009] Preferably, the soft-bristle roller brush includes a roller shaft and a brush sleeve detachably fitted onto the roller shaft, with the bristles of the soft-bristle roller brush disposed on the brush sleeve.
[0010] This utility model has the following beneficial effects: This invention utilizes a soft-bristled roller brush, a dust-blowing mechanism, and a cloth roller. The rapidly rotating soft-bristled roller brush removes sand and fine stones adhering to the belt surface. The dust-blowing mechanism then blows air along the belt surface to remove any remaining sand and fine stones. After passing through the cloth roller, the aggregate conveyor belt is wiped clean by friction. The soft-bristled roller brush, dust-blowing mechanism, and cloth roller all provide soft contact treatment for the aggregate conveyor belt, minimizing wear on the belt surface and effectively cleaning it.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] like Figure 1-5As shown, this utility model provides a technical solution: a self-cleaning aggregate conveyor, including a soft bristle roller brush 2, a dust blowing mechanism 3, and a cloth roller 4 arranged sequentially along the conveying direction below the top unloading end of the aggregate conveyor belt 1. The soft bristle roller brush 2 is arranged parallel to the aggregate conveyor belt 1 and is rotatably connected to the conveyor belt frame 5 and driven to rotate by a drive motor 6 fixed on the conveyor belt frame 5. The brush end of the soft bristle roller brush 2 extends to the outer side of the aggregate conveyor belt 1 to contact and rotate. The brush of the soft bristle roller brush 2 is made of polyester fiber soft bristles, which can make good soft contact with the belt surface. The soft bristle roller brush 2 includes a roller shaft 21 and a brush sleeve 22 detachably sleeved on the roller shaft 21. The brush of the soft bristle roller brush 2 is set on the brush sleeve 22. After the brush wears out, the brush sleeve 22 is partially replaced. The brush sleeve 22 is fixed to the roller shaft 21 by bolts and can be detachably installed, resulting in low maintenance costs. The dust blowing mechanism 3 is fixed on the conveyor frame 5 along the direction of the parallel aggregate conveyor belt 1. The dust blowing mechanism 3 includes an air guide pipe 31 and a fan 32. The air guide pipe 31 is provided with an air distribution hole 311. The air guide pipe 31 is supplied with air by the fan 32. The air distribution hole 311 of the air guide pipe 31 blows air towards the outside of the aggregate conveyor belt 1. The air distribution hole 311 on the air guide pipe 31 extends along the length of the air guide pipe 31. The air distribution hole 311 faces the direction of the soft brush 2. The air guide pipe 31 is located behind the guide roller 7. The air guide pipe 31 blows air along the inclined angle direction of the front belt surface guided by the guide roller 7 through the air distribution hole 311. The air with high pressure blown out through the air distribution hole 311 and the fan 32 blows down the fine sand and fine dust. The cloth roller 4 is fixed on the conveyor frame 5 along the direction parallel to the aggregate conveyor belt 1. The aggregate conveyor belt 1 is in contact with the roller surface of the cloth roller 4, and the cloth roller 4 is located outside the aggregate conveyor belt 1. Guide roller 7 and guide roller 8 are respectively set on both sides of the cloth roller 4 on the conveyor frame 5. The guide roller 7 and guide roller 8 are located inside the belt surface below the aggregate conveyor belt 1. The aggregate conveyor belt 1 passing between the roller surfaces of the guide roller 7 and guide roller 8 is pushed upward by the cloth roller 4, which facilitates better contact between the cloth roller 4 and the aggregate conveyor belt 1.
