Description

Technical Field

[0001] The present application relates to the technical field of conveyor belt cleaning, and in particular to a conveyor belt return cleaning device. Background Art

[0002] When conveyor belts are transporting soil and coal powder, in order to reduce dust, the conveyed materials are usually sprayed or sprinkled with water to maintain appropriate humidity. Sometimes, excessive humidity will cause lumps to adhere to the conveyor belt, making the conveyor belt surface very dirty, resulting in reduced transportation efficiency and increased energy consumption.

[0003] Existing cleaning devices usually use brushes to clean the surface of the conveyor belt, but sticky substances will adhere to the brushes, resulting in poor cleaning effects. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the present application provides a belt conveyor return cleaning device.

[0005] The present application provides a belt conveyor return cleaning device that adopts the following technical solution:

[0006] A belt conveyor return cleaning device is arranged on a conveyor frame. The device includes a bracket fixedly arranged on the conveyor frame, a pick-up plate is fixedly arranged on the bracket, a slide groove is provided on the pick-up plate, and a scraper is slidably arranged in the slide groove; a cylinder for controlling the lifting and lowering of the scraper is arranged on the bracket.

[0007] A further technical solution is that the pick plates, scrapers and cylinders are provided in two groups.

[0008] A further technical solution is that the upper end of the scraper is a curved surface.

[0009] This application has the following beneficial technical effects:

[0010] By providing a pick plate and a scraper that slides in contact with the pick plate, the scraper can scrape off the attachments on the conveyor belt, and the pick plate can remove the dirt on the scraper, thereby having a good cleaning effect on the attachments on the conveyor belt.

[0014] The technical solution in this application is further described in detail below with reference to the accompanying drawings.

[0015] The embodiment of the present application discloses a belt conveyor return cleaning device, which is arranged on the conveyor frame 1. Figure 1 and Figure 2 The device includes a bracket 2 fixedly arranged on the conveying frame 1, a pick-up plate 3 fixedly arranged on the bracket 2, a chute 4 is provided on the pick-up plate 3, a scraper 5 is slidably arranged in the chute 4; a cylinder 6 for controlling the lifting and lowering of the scraper 5 is provided on the bracket 2.

[0016] The bracket 2 is a U-shaped structure, straddling the conveyor frame 1. The picker plate 3 and scraper 5 are mounted vertically on the bracket 2. A side plate 7 is fixed vertically to the side of the scraper 5 adjacent to the cylinder 6. The piston rod of the cylinder 6 is fixed to the side plate 7 and is used to propel the scraper 5 upward and downward. The cylinder 6 propels the scraper 5 upward, causing it to contact the conveyor belt surface to scrape off debris. The cylinder 6 then drives the scraper 5 downward, removing debris from the scraper 5 via the picker plate 3, achieving self-cleaning.

[0017] The upper end of the scraper 5 is curved, reducing excessive friction from sharp edges on the conveyor belt. Two sets of scrapers 3, scrapers 5, and cylinders 6 are provided. The two scrapers 5 alternately scrape the conveyor belt, achieving a high cleaning effect. The bottom of the bracket 2 is provided with a rectangular hole 8, through which debris removed by the scraper 3 falls, preventing it from accumulating on the bracket 2.

[0018] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
