Description

Technical Field

[0001] The invention relates to the technical field of conveyors, in particular to a self-cleaning belt conveyor. Background Art

[0002] Belt conveyor is a continuous transport machine that uses conveyor belt as traction and load-bearing components. The conveyor belt is wrapped around driving rollers and various redirecting rollers, and is given appropriate tension by the tensioning device. When working, the conveyor belt is driven by the driving device and the friction and tension between the rollers and the conveyor belt are used to make the conveyor belt run. The material is continuously sent to the conveyor belt and moves with the conveyor belt, thereby realizing the transportation of the material. When cleaning, the traditional self-cleaning belt conveyor uses a brush to brush the surface of the belt to achieve the purpose of cleaning. However, when the brush is brushing, the dust brushed off is very easy to float in the air. This dust will endanger the health of surrounding personnel and is easily adsorbed to other places, increasing the cost of cleaning. In addition, the general self-cleaning device has the problem that when cleaning, dust is easily accumulated and blocked together, the device is stuck or the dust cannot be cleared, resulting in low cleaning efficiency.

[0003] Patent No. CN202322120736.X discloses a self-cleaning belt conveyor, in which a mounting plate B is provided with a mounting box B and a scraper, a through hole is provided in the mounting box B, the scraper is connected to the through hole and is in close contact with the conveying belt, and a collecting drawer B is inserted in the mounting box B, so when the conveying belt is running, larger adhesions on the surface of the conveying belt will be scraped off by the scraper, fall into the collecting drawer B through the through hole, and then can be pulled out regularly to clean the inside of the collecting drawer B, thereby enhancing the cleaning effect, reducing the wear of the brush sleeve by larger adhesions, and increasing the service life of the brush sleeve, and a guide plate is provided in the mounting box B, and the guide plate is connected to the through hole, so the installation of the guide plate is convenient. The device can block the adhesions scraped off by the scraper, prevent the splashing adhesions from flying to the outside, and conveniently collect them into the collection drawer B for cleaning. The cleaning box and the scraper are both provided with arc plates, so the arc plates can guide the cleaned adhesions, making it convenient for the adhesions to fall into the collection drawer A or the collection drawer B. Although this patent solves the above problems, there is still a problem that dust accumulation and blockage may occur during dust cleaning, affecting the cleaning efficiency. Therefore, a design that can prevent some dust and impurities that are easy to adhere to objects from accumulating on the top of the cleaning frame and causing blockage allows dust to continue to fall from the cleaning frame into the collection box to improve the cleaning efficiency is very necessary.
