The scraper plate is fixedly connected to the groove via the rotating rod, the bottom surface of the scraper plate is fixedly connected to the telescopic rod, and the top of the scraper plate penetrates through the scraper plate and extends to the outside of the scraper plate." In use, the scraper plate, through which the telescopic rod and spring drive the scraper plate to move, cleans the material adhering to the surface of the conveyor belt. Furthermore, through the cooperation of the movable rod and the limiting port, the movable rod drives the scraper plate to perform secondary cleaning of the conveyor belt.

[0004] However, traditional scrapers are mostly rigid structures, which cannot automatically avoid tightly adhered materials, easily causing the conveyor belt to tear and be damaged due to excessive force. Moreover, relying solely on the scraping action of the scraper is not effective in removing some stubborn materials, and cannot meet high cleaning requirements.

[0005] Therefore, we provide a scraping mechanism for belt conveyors to solve the above problems. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a scraping mechanism for belt conveyors, aiming to solve the aforementioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A scraping mechanism for a belt conveyor includes a support frame, a conveyor belt mounted on the inner side of the support frame, a scraping and cleaning assembly disposed on the lower side of the conveyor belt, the scraping and cleaning assembly including a support plate mounted on the right end of the support frame, a support spring disposed on the upper side of the support plate, a scraper mounted on the top of the support spring, a cleaning frame disposed on the left side of the support plate, a high-pressure nozzle mounted inside the cleaning frame, and a cleaning water tank disposed on the lower side of the cleaning frame.

[0008] As a further description of the above technical solution: The support plate is made of stainless steel, and five sets of support springs are evenly arranged. The front and rear ends of the scraper are connected to the support frame by a sliding groove, and the scraper is in contact with the lower surface of the conveyor belt.

[0009] As a further description of the above technical solution: The top of the scraper has an arc-shaped structure, and the scraper is made of hard plastic.

[0010] As a further description of the above technical solution: The cleaning frame is attached to the lower surface of the conveyor belt, the inner wall of the cleaning frame is inclined inward, two rows of high-pressure nozzles are symmetrically arranged about the central axis of the cleaning frame, a high-pressure water pump is installed at the front end of the cleaning water tank, and the high-pressure nozzles and the high-pressure water pump are connected by a pipe.

[0011] As a further description of the above technical solution: A cleaning roller is rotatably connected to the inner middle of the cleaning frame. A servo motor is provided on the rear side of the cleaning frame, and the output end of the servo motor is connected to the cleaning roller by a flat key.

A water removal scraper is attached to the upper surface of each connecting plate. A drainage trough is provided at the bottom of the connecting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention, through the arrangement of a support spring, scraper, high-pressure nozzle, and cleaning roller, ensures that when the conveyor belt is running, the material adhering to the conveyor belt is scraped off by the scraper, keeping the conveyor belt clean. When encountering material that is too tightly adhered to be easily scraped off, the arc-shaped structure at the top of the scraper will be stressed, causing the support spring to contract downwards, thereby driving the scraper to move downwards. This avoids excessive rigid contact that could cause tearing or damage to the conveyor belt. When the conveyor belt continues to run into the cleaning frame, the high-pressure nozzle sprays water at high pressure to rinse the material adhering to the lower surface of the conveyor belt. Meanwhile, a servo motor drives the cleaning roller to rotate, and the nylon brushes on the surface of the cleaning roller scrub the lower surface of the conveyor belt, further removing residual material and dirt, and improving the cleaning effect.

[0015] This invention utilizes a mounting plate, a filter screen, and a dewatering scraper. The filter screen separates water and materials, and the filtered water enters a cleaning tank for recycling.

[0018] 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.

[0019] Please see Figure 1-6 As shown, this utility model provides a technical solution: a scraping mechanism for a belt conveyor, including a support frame 1, a conveyor belt 2 installed on the inner side of the support frame 1, a scraping and cleaning assembly 3 provided on the lower side of the conveyor belt 2, the scraping and cleaning assembly 3 including a support plate 301 installed on the right end of the support frame 1, a support spring 302 provided on the upper side of the support plate 301, a scraper 303 installed on the top of the support spring 302, a cleaning frame 304 provided on the left side of the support plate 301, a high-pressure nozzle 305 installed inside the cleaning frame 304, and a cleaning water tank 306 provided on the lower side of the cleaning frame 304.

[0020] Furthermore, the support plate 301 is made of stainless steel, and five sets of support springs 302 are evenly arranged. The front and rear ends of the scraper 303 are connected to the support frame 1 by a sliding groove. The scraper 303 is in contact with the lower surface of the conveyor belt 2. When the conveyor belt 2 is running, the material adhering to the conveyor belt 2 will be scraped off by the scraper 303 to ensure the cleanliness of the conveyor belt 2. At the same time, the support springs 302 support the scraper 303, increasing the contact between the scraper 303 and the conveyor belt 2 and improving the scraping effect.

[0021] Furthermore, the top of the scraper 303 has an arc-shaped structure and is made of hard plastic. When it encounters materials that are too tightly stuck and cannot be easily scraped off, the arc-shaped structure at the top of the scraper 303 will be stressed, causing the support spring 302 to contract downwards, thereby driving the scraper 303 to move downwards, thus avoiding excessive rigid contact that could cause the conveyor belt 2 to tear and be damaged.

[0022] Furthermore, the cleaning frame 304 is attached to the lower surface of the conveyor belt 2, and the inner wall of the cleaning frame 304 has an inwardly inclined structure. Two rows of high-pressure nozzles 305 are symmetrically arranged about the central axis of the cleaning frame 304. A high-pressure water pump 307 is installed at the front end of the cleaning water tank 306. The high-pressure nozzles 305 and the high-pressure water pump 307 are connected by a pipe. When the high-pressure water pump 307 is working, it pressurizes the water in the cleaning water tank 306 and delivers it to the high-pressure nozzles 305. The high-pressure nozzles 305 spray water in a high-pressure form to wash the material adhering to the lower surface of the conveyor belt 2. The inwardly inclined structure of the inner wall of the cleaning frame 304 helps to guide the washed water and material to one side of the cleaning frame 304 for subsequent collection and treatment.

[0023] Furthermore, a cleaning roller 308 is rotatably connected to the inner middle of the cleaning frame 304. A servo motor is installed on the rear side of the cleaning frame 304, and the output end of the servo motor is connected to the cleaning roller 308 by a key. Nylon brushes are installed on the surface of the cleaning roller 308. During the rinsing process, the servo motor drives the cleaning roller 308 to rotate, so that the nylon brushes on the surface of the cleaning roller 308 will brush the lower surface of the conveyor belt 2, further removing residual materials and dirt, and improving the cleaning effect.

[0024] Furthermore, a mounting plate 309 is provided on the lower side of the cleaning roller 308. The mounting plate 309 is slidably connected to the cleaning frame 304. A filter screen 310 is installed on the inner side of the mounting plate 309. The filter screen 310 is made of stainless steel. A pull handle 311 is welded to the front end of the mounting plate 309. During rinsing and scrubbing, the material and water that fall will pass through the filter screen 310. The filter screen 310 separates the water and material. The filtered water enters the cleaning water tank 306 for recycling. When the material accumulates to a certain extent, the mounting plate 309 and the filter screen 310 can be pulled out from the cleaning frame 304 by pulling the handle 311, which facilitates the cleaning of the filter screen 310 and the collection of material.

[0025] Furthermore, a dewatering trough 312 is provided on the left side of the cleaning frame 304. A connecting plate 313 is installed on the inner side of the dewatering trough 312. There are three sets of connecting plates 313. A dewatering scraper 314 is attached to the upper surface of each connecting plate 313. A drainage groove is opened at the bottom of the connecting plate 313. When the conveyor belt 2, after being brushed by the cleaning roller 308, continues to run to the dewatering trough 312, the lower surface of the conveyor belt 2 will come into contact with the dewatering scraper 314. The dewatering scraper 314 will perform a final scraping treatment on the lower surface of the conveyor belt 2, scraping off the residual water and a small amount of material, ensuring that the conveyor belt 2 is dry and clean. At the same time, the drainage groove design at the bottom of the connecting plate 313 helps to quickly drain the scraped water and material, avoiding accumulation in the dewatering trough 312 and affecting the dewatering effect.

[0026] Working Principle: When this device is installed in the working position, the conveyor belt 2 rotates continuously during the operation of the belt conveyor. As the conveyor belt 2 rotates, the material adhering to it is scraped off by the scraper 303. When encountering material that is too tightly adhered to be easily scraped off, the arc-shaped structure at the top of the scraper 303 is stressed, causing the support spring 302 to contract downwards, thus moving the scraper 303 downwards. This prevents excessive rigid contact from causing tearing damage to the conveyor belt 2. When the conveyor belt 2 continues to rotate into the cleaning frame 304, the high-pressure water pump 307 pressurizes the water in the cleaning water tank 306 and delivers it to the high-pressure nozzle 305. The high-pressure nozzle 305 sprays water at high pressure to wash the material adhering to the lower surface of the conveyor belt 2. During the washing process, the servo motor drives the cleaning roller 308 to rotate, causing the nylon brushes on the surface of the cleaning roller 308 to scrub the lower surface of the conveyor belt 2, further removing residual material. During rinsing and washing, the material and water that fall off will pass through the filter screen 310, which separates the water and material. The filtered water enters the cleaning water tank 306 for recycling. When the material accumulates to a certain extent, the mounting plate 309 and the filter screen 310 are pulled out from the cleaning frame 304 by pulling the handle 311 to clean the filter screen 310 and collect the material. When the conveyor belt 2, after being brushed by the cleaning roller 308, continues to run to the dewatering tank 312, the lower surface of the conveyor belt 2 will come into contact with the dewatering scraper 314. The dewatering scraper 314 will perform a final scraping treatment on the lower surface of the conveyor belt 2, scraping off the residual water and a small amount of material to ensure that the conveyor belt 2 is dry and clean. At the same time, the drainage groove design at the bottom of the connecting plate 313 helps to quickly drain the scraped water and material, preventing them from accumulating in the dewatering tank 312. This completes the use process of a scraping mechanism for a belt conveyor.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
