[0002] In mining and material transportation, belt conveyors serve as crucial equipment, undertaking a significant amount of material transport tasks. However, due to the complex mining environment, materials often contain a large number of fine particles and sticky substances, which easily adhere to the belt surface, forming a mineral powder layer. The accumulation of this mineral powder layer not only increases the belt's operating resistance, leading to increased energy consumption, but also accelerates belt wear and shortens its service life. Furthermore, the adhesion of mineral powder can affect the normal transport of materials, causing uneven transport and even clogging related components of the belt conveyor. Currently, the cleaning of mineral powder adhering to the belt surface typically involves manual cleaning or simple mechanical scraper cleaning. However, these methods are inefficient, incomplete, and pose safety hazards for manual cleaning. Summary of the Invention

[0020] Please see Figure 1-4This utility model provides a technical solution: a device for cleaning mineral powder adhering to the surface of a mining conveyor belt, including a conveyor belt 1 and a cleaning mechanism. The cleaning mechanism is installed at the bottom of the conveyor belt 1 to clean the belt at the bottom of the conveyor belt 1 without affecting the normal operation of the belt. The cleaning mechanism includes a water spraying unit and a recycling unit. The water spraying unit can spray water to clean the belt, and the recycling unit can purify the wastewater after cleaning for reuse. The water spraying unit includes a water storage tank 2, a water spray pipe 3, multiple nozzles 4, and water... Pump 5, water inlet pipe 6, and drain pipe 7 are provided. Water storage tank 2 is located below belt conveyor 1. Water spray pipe 3 is fixedly installed on the front and rear sides of water storage tank 2. Multiple nozzles 4 are fixedly installed on water spray pipe 3, with the nozzles 4 facing the belt to ensure direct washing of the belt. Water pump 5 is located on the front side of water storage tank 2.

One end of drain pipe 7 is fixedly connected to the water outlet of water pump 5, and the other end of drain pipe 7 is fixedly connected to one end of water spray pipe 3.

[0021] Specifically, the recycling unit includes multiple springs 8, a filter screen 9, a gearbox 10, two drive shafts 11, two eccentric wheels 12, a drive shaft 13, a motor 14, two first bevel gears 15, and two second bevel gears 16. The multiple springs 8 are fixedly installed on the left and right sides of the water storage tank 2. A drain outlet is located on the right side of the water storage tank 2. The filter screen 9 is fixedly installed on top of the multiple springs 8 and extends through the drain outlet. The filter screen 9 is angled to facilitate the removal of mineral powder and impurities. The gearbox 10 is fixedly installed in the water storage tank 2. On the outer rear side, two drive shafts 11 are rotatably connected to the front and rear sides of the water storage tank 2 respectively. Two eccentric wheels 12 are fixedly mounted on the two drive shafts 11. The two ends of the drive shaft 13 are rotatably connected to the left and right sides of the gearbox 10 respectively. The motor 14 is fixedly mounted on the outer rear side of the water storage tank 2, and the drive end of the motor 14 is fixedly connected to one end of the drive shaft 13. Two first bevel gears 15 are fixedly mounted on the drive shaft 13, and two second bevel gears 16 are fixedly mounted on the two drive shafts 11 respectively. The first bevel gears 15 mesh with the corresponding second bevel gears 16.

[0022] Specifically, a collection box 17 is fixedly installed on the right side of the sewage outlet, and a sewage pipe 18 is installed at the bottom of the collection box 17. The mineral powder that falls off the filter screen 9 will slide into the collection box 17 and then be discharged through the sewage pipe 18.

[0023] Specifically, a scraper 19 is fixedly installed between the front and rear sides of the water storage tank 2, and the top of the scraper 19 is tightly fitted with the bottom of the belt conveyor 1. The scraper 19 can scrape the water on the belt into the water storage tank 2 to prevent water from dripping onto the ground.

[0024] Specifically, a liquid level sensor 20 is fixedly installed on the left side of the water storage tank 2, which can detect the liquid level in the water storage tank 2 in real time.

[0025] Specifically, a water supply pipe 21 is fixedly installed on the front side of the water storage tank 2, and the water supply pipe 21 is used to replenish water to the water storage tank 2.

[0026] Working Principle: During cleaning, when the bottom of the conveyor belt 1 reaches below the cleaning mechanism, the water spray unit starts working. The water pump 5 outside the water storage tank 2 starts, drawing clean water or recycled water from inside the tank 2 through the inlet pipe 6, and then sending the water through the drain pipe 7 to the spray pipes 3 fixed on both sides of the water storage tank 2. Multiple nozzles 4 evenly distributed on the spray pipes 3 then spray water jets towards the bottom of the moving conveyor belt, directly and powerfully washing the surface of the belt with adhering mineral powder. This impacts and peels off loosely attached mineral powder and some stubborn adhesive, mixing it with the water. Simultaneously, the scraper 19, installed between the front and rear sides of the water storage tank 2, has its top tightly fitted to the bottom of the conveyor belt. As the belt moves, the scraper 19 scrapes away the water film remaining on the surface of the belt after washing and guides this water into the water storage tank 2 below, effectively preventing water droplets from falling onto the ground and causing slipperiness or waste. The wastewater containing mineral powder scraped into the water storage tank 2 then enters the recycling unit for purification treatment. The core of the recycling unit is an inclined filter screen 9, through which wastewater first flows. The surface of the filter screen 9 traps mineral powder, impurities, and larger particles washed away. The motor 14 on the rear side of the water storage tank 2 starts, driving the drive shaft 13 to rotate. Two first bevel gears 15 are fixed to the drive shaft 13, meshing with two second bevel gears 16, which are fixed to the transmission shafts 11 rotating on the front and rear sides inside the water storage tank 2. Therefore, the rotation of the motor 14, through the bevel gears, drives the two transmission shafts 11 to rotate synchronously. Each transmission shaft 11 has an eccentric wheel 12 fixed to it. As the transmission shaft 11 rotates, the eccentric wheels 12 rotate. The thrust generated by the rotation of the eccentric wheels 12 periodically acts on the filter screen 9, overcoming the elastic resistance of the spring 8, causing the filter screen 9 to vibrate at high frequency under the action of the spring 8. This continuous vibration effectively shakes off mineral powder and impurities adhering to the surface of the filter screen 9, preventing them from clogging the mesh. The shaken-off mineral powder and impurities, due to the inclined design of filter screen 9, will naturally slide down by gravity and enter the collection box 17 connected to the right side through the drain port below filter screen 9 for centralized collection. After initial purification by filter screen 9, the water will remain in water storage tank 2, which can be pumped by water pump 5 for the next round of water spraying, thus realizing water recycling. The liquid level sensor 20 in water storage tank 2 monitors the water level in real time. When the water level is too low, it can trigger water supply pipe 21 to automatically replenish water to water storage tank 2, ensuring the continuous and stable operation of the entire cleaning system. The entire process does not require stopping the normal operation of belt conveyor 1, realizing automated and efficient cleaning of mineral powder at the bottom of the belt.
