Description

Technical Field

[0001] This utility model relates to the field of conveyor cleaning technology, specifically a belt conveyor cleaner. Background Technology

[0002] Belt conveyors are a common type of continuous conveying equipment, widely used in industries such as mining, metallurgy, chemical, building materials, power, and grain. They are used for horizontal or inclined conveying of bulk materials or packaged goods. When a belt conveyor is conveying goods, some impurities will adhere to its outer side. In order to improve the stable conveying capacity of the conveyor, it is necessary to clean the inner side of the conveyor belt, which requires the use of a cleaner.

[0003] A belt conveyor cleaner, disclosed in CN220501849U, is installed on the return section of the conveyor belt. It includes a scraper and a U-shaped support. The U-shaped support includes a horizontal plate, a fixed vertical plate on the upper rear side of the horizontal plate, and a movable vertical plate that can be adjusted forward and backward on the upper front side. A pressure roller is rotatably mounted between the fixed and movable vertical plates. Below the pressure roller is a vertically adjustable support roller with an embedded groove at its top. The scraper is spring-loaded and positioned within the embedded groove, with its top protruding above the groove. By using the U-shaped support and the pressure roller and support roller positioned between the fixed and movable vertical plates, with the scraper mounted on the support roller via a spring, and the conveyor belt positioned between the pressure roller and support roller, the scraper prevents the conveyor belt from shifting upwards when the scraper is cleaning the conveyor belt, increasing the scraping force and improving the cleaning effect. The scraper, spring-loaded and positioned within the embedded groove, allows for elastic deformation, preventing the scraper from rigidly obstructing the conveyor belt and causing tearing of the scraper or conveyor belt.

[0004] The device is equipped with scrapers to clean impurities adhering to the outside of the conveyor belt, but it lacks a dust removal structure. The dust cannot be completely removed by the scrapers alone. If the dust is not cleaned in time, it will not only adhere to the goods, affecting their quality, but also easily damage the conveyor if it falls into the transmission components, thus affecting the use of the conveyor.

[0005] To address the aforementioned issues, we have implemented an innovative design based on the existing belt conveyor cleaner structure. Utility Model Content

[0006] The purpose of this utility model is to provide a belt conveyor cleaner to solve the problem mentioned in the background art that the device does not have a dust removal structure, the dust cannot be completely cleaned by the scraper, and if the dust is not cleaned in time, the dust will not only adhere to the goods and affect the quality of the goods, but if the dust falls into the transmission components, it will easily cause damage to the conveyor, thereby affecting the use of the conveyor.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a belt conveyor cleaner, comprising a base, with support plates fixedly installed on the left and right sides of the base; further comprising: a drive motor, the drive motor being fixedly installed on the outside of the support plates, with the output end of the drive motor penetrating through the inside of the support plates; a drive roller, the drive roller being fixedly connected to the output end of the drive motor; a transmission roller, the transmission roller being rotatably connected to the inside of the support plates; a conveyor belt, the two ends of the conveyor belt being respectively connected to the drive roller and the transmission roller; a cleaning assembly, the cleaning assembly being disposed on the side of the return section of the conveyor belt; and a dust removal assembly, the dust removal assembly being disposed on the upper end of the conveyor belt; wherein, the cleaning assembly is used to scrape off impurities adhering to the return section of the conveyor belt; and the dust removal assembly is used to clean dust adhering to the outside of the conveyor belt.

[0008] Preferably, the cleaning assembly includes a fixed plate, a sliding rod, and a scraper. The fixed plate is fixedly installed between the left and right support plates, and the sliding rod is slidably connected to the inner side of the fixed plate. The scraper is fixedly connected to the tail end of the sliding rod, and the scraper and the side end of the return section are distributed in a left-right correspondence.

[0009] Preferably, the cleaning assembly further includes a telescopic spring, the two ends of which are connected to a fixed plate and a scraper, respectively.

[0010] Preferably, the dust removal component includes an elastic airbag, an air tube, and an air nozzle. The elastic airbag is fixedly installed on the outside of the support plate, and the elastic airbag is connected to the air nozzle through the air tube.

[0011] Preferably, the air nozzle is fixedly installed on the inner side of the support plate, and the air nozzle is set at an angle of 45° when viewed from the front.

[0012] Preferably, the dust removal assembly further includes a gear, which is fixedly connected to the output end of the drive motor, and the gear has a half-tooth structure when viewed from the side.

[0013] Preferably, the dust removal assembly further includes a chute, a sliding block, a rack, a push plate, and a return spring. The chute is formed inside the support plate, and a sliding block is slidably connected to the inside of the chute. A rack is fixedly connected to the outside of the sliding block, and the rack meshes with an outer gear. A push plate is fixedly connected to the tail end of the rack, and the push plate and the elastic airbag are distributed in a left-right correspondence. A return spring is connected between the inner wall of the chute and the sliding block.

[0014] Compared with the prior art, the beneficial effect of this utility model is that the belt conveyor cleaner is equipped with:

[0015] 1. Impurity cleaning structure: The scraper is set on the side of the return section of the conveyor belt, so as to avoid the scraper affecting the conveying of goods on the conveyor belt. The scraper is always in close contact with the outside of the conveyor belt by the elastic force of the telescopic spring. The scraper removes the impurities adhering to the outside of the conveyor belt by blocking the scraper, thereby improving the cleanliness of the conveyor belt.

[0016] 2. Dust cleaning structure: When the output end of the drive motor rotates, it will synchronously drive the gear to rotate. When the gear teeth mesh with the rack, it will drive the sliding block on the outside of the rack to slide along the inner side of the groove, thereby causing the push plate at the tail end of the rack to move towards the elastic air bladder and squeeze the elastic air bladder. After the elastic air bladder is squeezed, the gas inside it will be transported to the air nozzle through the air pipe. The gas sprayed out through the air nozzle will clean the dust adhering to the upper end of the conveyor belt.

[0017] Furthermore, when the gear teeth separate from the rack, the sliding block will be reset by the elastic force of the return spring, thereby driving the push plate at the tail end of the rack away from the elastic airbag. The elastic airbag resets and inflates by its own elastic force. Through the reciprocating operation of the above structure, the air nozzle will repeatedly spray air onto the upper end of the conveyor belt to clean the dust adhering to the upper end of the conveyor belt.

The cleaning assembly 7 is used to scrape off impurities adhering to the return section of the conveyor belt 6; and the dust removal assembly 8 is used to clean dust adhering to the outside of the conveyor belt 6.

[0028] The cleaning assembly 7 includes a fixed plate 701, a sliding rod 702, and a scraper 703. The fixed plate 701 is fixedly installed between the left and right support plates 2, and the sliding rod 702 is slidably connected to the inner side of the fixed plate 701. The scraper 703 is fixedly connected to the tail end of the sliding rod 702, and the scraper 703 is distributed in a left-right correspondence with the side end of the return section. The cleaning assembly 7 also includes a telescopic spring 704, and the two ends of the telescopic spring 704 are respectively connected to the fixed plate 701 and the scraper 703.

[0029] The scraper 703 is located on the side of the return section of the conveyor belt 6, thereby preventing the scraper 703 from affecting the conveying of goods on the conveyor belt 6. The scraper 703 is always tightly attached to the outside of the conveyor belt 6 by the elastic force of the telescopic spring 704. The scraper 703 removes impurities adhering to the outside of the conveyor belt 6 by blocking the impurities, thereby improving the cleanliness of the conveyor belt 6.
