[0002] Intelligent return scraper devices are mainly used in mines, power plants and other places, and are usually installed below the return surface of the belt conveyor. The main components of this device include power components (motor reducer), scrapers and silos. The power component is responsible for providing power to drive the scraper to move; the silo is used to receive the residual materials on the belt dropped by the second sweeper on the return surface of the belt conveyor; the scraper scrapes the materials that fall into the silo into the hopper or designated location to achieve the reuse or centralized treatment of the materials. This type of device plays a key role in large-scale material transportation and processing systems, and can effectively clean the residual materials on the belt to ensure the normal operation of the equipment and the full utilization of materials.

[0003] However, the intelligent return scraper device in the prior art has some significant defects and problems: 1. The scraper device usually uses a metal scraper, which generates a lot of noise during operation. This not only affects the comfort of the working environment, but may also have an adverse effect on the health of the operator; 2. The metal scraper is easy to scratch the bottom plate when it contacts the bottom plate, especially when the chain sags severely, which not only increases the maintenance cost of the equipment, but may also increase the downtime of the equipment and affect production efficiency 3. The existing scraper chain sags severely, and it is difficult to adjust the distance between the bottom plate and the lower surface of the scraper, which easily leads to unclean material cleaning or damage to the bottom plate. The sagging of the chain will also affect the cleaning effect of the scraper, so that the material cannot be completely scraped into the silo or the designated position. Utility Model Content

[0004] The utility model aims to solve the problems in the prior art and provides an intelligent return scraper device with low running noise, not easy to scratch the bottom plate, adjustable chain sag, and intelligent control start and stop.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: an intelligent return scraper device, comprising a cabin, a driving mechanism and a scraping mechanism, wherein the driving mechanism comprises a reduction motor fixedly mounted on the left side of the front surface of the cabin, the output end of the reduction motor is connected to a driving shaft through a coupling, and the rear end of the driving shaft passes through the front wall of the cabin and extends into the rear wall thereof, driving sprockets are symmetrically mounted on the front and rear sides of the outer surface of the driving shaft, the outer surfaces of the two driving sprockets are both connected to chains, the inner sides of the right ends of the two chains are both connected to driven sprockets, the centers of the two driven sprockets are connected to driven shafts, and the inner sides of the two chains are both installed with support components;

[0027] Specifically, the driving mechanism 200 includes a reduction motor 201 fixedly installed on the left side of the front surface of the cabin 100, the output end of the reduction motor 201 is connected to the driving shaft 202 through a coupling, and the rear end of the driving shaft 202 passes through the front wall of the cabin 100 and extends into its rear wall, and driving sprockets 203 are symmetrically installed on the front and rear sides of the outer surface of the driving shaft 202, the outer surfaces of the two driving sprockets 203 are both connected to the chains 204, the inner sides of the right ends of the two chains 204 are both connected to the driven sprockets 205, the centers of the two driven sprockets 205 are connected to the driven shaft 206, and the inner sides of the two chains 204 are both installed with support assemblies 207, wherein the reduction motor 201 transmits power to the driving shaft 202 through the coupling, the driving shaft 202 drives the driving sprocket 203 to rotate, and the driving sprocket 203 drives the driven sprocket 205 and the driven shaft 206 through the chain 204, so that the entire chain system operates. The support assembly 207 is installed in the middle of the chain to prevent the chain from sagging, ensure the stable operation of the scraper assembly, and achieve efficient cleaning of the material.

[0028] Furthermore, the scraping mechanism 300 includes a mounting plate 301 fixedly mounted on opposite surfaces of two chains 204, and a scraper 302 is fixedly mounted between the two mounting plates 301, wherein the mounting plate 301 is fixed on the inner side surface of the chain 204, and the movement of the chain 204 drives the mounting plate 301 to move together, and the scraper 302 is fixedly mounted between the two mounting plates 301, and is used to scrape the residual material on the return surface of the belt conveyor. The driving mechanism 200 outputs the power of the reduction motor 201, and is connected to the driving shaft 202 through the coupling transmission, and the driving shaft 202 drives the driving sprocket 203 to rotate, and the driving sprocket 203 drives the driven sprocket 205 and the driven shaft 206 through the chain 204, thereby driving the chain 204 to move.

The movement of the chain 204 drives the mounting plate 301 and the scraper 302 fixed thereon to scrape the material. The support assembly 207 ensures that the chain 204 maintains appropriate tension during operation to prevent sagging, thereby ensuring the stable operation of the scraper 302 and the efficient cleaning of the material. The scraper 302 made of polymer polyethylene material has the advantages of wear resistance and low noise when scraping materials, avoiding damage to the bottom plate. The design of the lifting ring 101 and the support seat 102 facilitates the installation, movement and stable operation of the equipment. Through the coordinated work of these components, the device realizes efficient, low noise and stable material cleaning functions, which significantly improves the operation effect and service life of the equipment.
