[0019] 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.

[0020] Please see Figure 1-6As shown, a bucket elevator with a dust-proof structure includes a base 1 and a dust collection box 5. The top of the base 1 is bolted to the elevator body 2, which is an existing bucket elevator structure. Its specific structure and operation are not described in detail here. A feed inlet 3 is provided on one side of the elevator body 2 for filling with limestone material, and the feed inlet 3 is connected to the inlet of the elevator body 2. A cleaning port 8 is provided on the lower side of the elevator body 2 away from the feed inlet 3. When material jamming or blockage occurs inside the elevator body 2, it can be cleaned through the cleaning port 8, effectively preventing dangerous situations. A gate is provided on the outside of the cleaning port 8; the gate can be opened when cleaning and maintenance are required. An outlet 6 is provided above the cleaning port 8, and one side of the outlet 6 is connected to the elevator body 2. The components are interconnected, with the discharge port 6 leading into one side of the elevator body 2 and bolted together for easy material reception. This reduces material spillage during operation, preventing material accumulation at the bottom of the device. A dust collection box 5 has a dust extraction mechanism 4 on one side to remove residual dust from the elevator body 2, preventing dangerous situations and improving the machine's operating efficiency. The dust collection box 5 collects dust, achieving resource recycling and protecting the environment and human health. An internal dust cleaning mechanism 7 cleans dust from the inner wall of the elevator body 2, reducing dust buildup and ensuring device safety. This also makes the machine run more smoothly and improves work efficiency.

[0021] The dust removal mechanism 7 includes a second motor 71, the output shaft of which is bolted to a second rotating shaft 72. A fixed housing 73 is connected to the bottom of the second rotating shaft 72. The fixed housing 73 effectively protects its internal components, reducing dust wear. The fixed housing 73 and the second rotating shaft 72 are rotatably connected. A threaded rod 74 is connected to the bottom of the second rotating shaft 72 via a belt pulley. The threaded rod 74 is located inside the elevator body 2. A fixed sleeve 75 is provided on the surface of the threaded rod 74, and the fixed sleeve 75 is threadedly connected to the threaded rod 74. Scrapers 76 are bolted to both ends of the fixed sleeve 75. There are four scrapers 76, each facing one of the four surfaces of the inner wall of the elevator body 2. The scrapers 76 can clean the dust adhering to the inner wall of the elevator body 2, causing the dust to fall off and facilitating subsequent dust treatment. A fixing plate 77 is bolted to the top of the scraper 76, and an electric push rod 78 is bolted to one side of the fixing plate 77. The electric push rod 78 is protected by a shell to reduce the wear of the electric push rod 78 by dust. A push plate 79 is bolted to the output end of the electric push rod 78. Under the action of the electric push rod 78, the push plate 79 can collide with the hopper inside the elevator body 2 to knock out the residual dust in the hopper, providing convenience for subsequent work.

[0022] The dust collection mechanism 4 includes a first motor 42 and centrifugal blades 46. A mounting base 44 is bolted to the bottom of the first motor 42 to secure it and ensure stability. A first rotating shaft 43 is bolted to the output shaft of the first motor 42. The other end of the first rotating shaft 43 is connected to a square outer casing 41, and the first rotating shaft 43 and the square outer casing 41 are rotatably connected. The square outer casing 41 can seal the absorbed dust, preventing it from escaping into the air and protecting human health. A fan casing 45 is bolted inside the square outer casing 41, and the centrifugal blades 46 pass through the shaft... The first rotating shaft 43 is connected to the fan housing 45 and is connected to the fan housing 45 and fixed to the bearing of the centrifugal blade 46. An exhaust duct 47 is bolted to one side of the fan housing 45 and the exhaust duct 47 is connected to the fan housing 45 at the connection point. An exhaust port 49 is bolted to one end of the exhaust duct 47 and is bolted through to the square housing 41. An exhaust port 48 is bolted through to the surface of the square housing 41 away from the first motor 42 and is connected to the fan housing 45. The other end of the exhaust port 48 is connected to the hoist body 2.

[0023] Working Principle: The device is fixed in a designated position. After a period of operation, a large amount of limestone dust accumulates inside the hoist body 2. At this time, the first motor 42 is activated, driving the first rotating shaft 43 to rotate. The rotation of the first rotating shaft 43 causes the bearings of the centrifugal blades 46 to rotate, thereby driving the centrifugal blades 46 to rotate. The rotation of the centrifugal blades 46 generates centrifugal force, similar to the principle of centrifugal fan blades, creating negative pressure in the middle section. This draws the limestone dust out of the hoist body 2 through the exhaust port and into the dust collection box 5 through the exhaust port 49 of the exhaust duct 47, collecting and recycling the limestone dust. This reduces environmental pollution and protects the health of the workers. After the device has been operating for a long time, the hoist... A large amount of limestone dust adheres to the inner wall of the main body 2. At this time, the second motor 71 is turned on to drive the second rotating shaft 72 to rotate, which drives the threaded rod 74 to rotate through the belt pulley. This causes the fixed sleeve 75 to move up and down reciprocally. The fixed sleeve 75 drives the scraper 76 to move up and down reciprocally, which can scrape off the limestone dust adhering to the inner wall of the elevator body 2. Then, the electric push rod 78 can be turned on to push the push plate 79 to slightly collide with the already scattered hopper, so that the limestone dust remaining in the hopper can be shaken off and fall off. The dust collection mechanism 4 can absorb and collect it, so that the limestone dust on the inner wall of the elevator body 2 is absorbed, reducing dust and strengthening the protection of the device, improving the efficiency of equipment operation and extending the service life of the equipment.
