Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor cleaning, in particular to a cleaning device for the head of a belt conveyor. Background Art

[0002] Belt conveyor, also known as belt conveyor, is a continuous conveying equipment widely used in industrial production. Its main function is to transport bulk materials, powders, small blocks and packaged finished products through the continuous rolling of the conveyor belt. Belt conveyor can transport materials in horizontal, inclined and even vertical directions. It is an efficient and continuous material conveying equipment. However, during the use of belt conveyor, due to the contact between the conveying surface of the belt conveyor and the materials, especially for some materials with high viscosity and water content, the materials often adhere to the conveying surface of the belt conveyor and are difficult to clean. After the belt conveyor completes unloading, the attachments on its surface will continue to move with the operation of the belt conveyor, increasing the return material, which is not conducive to the use of the belt conveyor.

[0003] In order to clean the conveying surface of the belt conveyor, in the existing structure, a scraper is often installed on the belt conveyor. During the operation of the belt conveyor, the scraper will scrape the material attached to the belt conveyor. However, after the scraper scrapes the material on the belt conveyor, the material will be transferred and attached to the scraper. Although some of the material will slide down the scraper under the action of gravity, some of the material will still remain and adhere to the scraper. Over time, the material attached to the scraper will continue to thicken. If left alone, the material will condense into blocks and continue to cover the scraper blade, which will affect the scraping and cleaning effect of the scraper on the conveying surface of the belt conveyor.

[0004] Based on the above situation, it is necessary to design a cleaning device for the head of the belt conveyor to solve the above problems. Utility Model Content

[0005] The utility model provides a cleaning device for a belt conveyor head to solve the problem of cleaning the belt conveyor head in the prior art.

The scraper is located below the belt conveyor body, and the output end of the scraper is in contact with the transportation surface of the belt conveyor body. On one side of the scraper close to the discharge end of the belt conveyor body, a scraping plate is provided, and the scraping plate is in close contact with the side surface of the scraper. A driving component for driving the scraping plate to reciprocate on the surface of the scraper is provided on the suspension. On one side of the scraper close to the scraping plate, a water spraying tank connected to a water pump is provided, and the output end of the water spraying tank faces the contact surface between the scraper and the scraping plate.

[0008] Preferably, a tool rest is rotatably connected to the suspension, the scraper is fixedly installed on the tool rest, a drainage box is fixedly connected to the tool rest, and the input end of the drainage box is located at a position on the side surface of the scraper close to the scraping plate.

[0009] Preferably, the driving component includes a threaded rod rotatably connected to the tool rest, a pulley one fixedly connected to one end of the threaded rod, a pulley two fixedly connected to the tool rest, a transmission belt sleeved on the pulley one and the pulley two, and a motor connected to the drainage box. The threaded rod is threadedly connected to the scraping plate, and the output end of the motor is connected to the pulley two.

[0010] Preferably, the water spraying tank is fixedly connected to the tool rest, and the water spraying tank is composed of a box body and a water spraying nozzle. A water guide pipe is communicated between the input end of the box body and the output end of the water pump. The water pump is installed on the suspension, the water spraying nozzle is communicated with the output end of the box body, and the output direction of the water spraying nozzle faces the contact surface between the scraper and the scraping plate.

[0011] Preferably, a sliding rod corresponding to the position of the threaded rod is fixedly connected to the tool rest, and the scraping plate is slidably connected to the sliding rod.

[0012] Preferably, a fixing plate is fixedly connected to the suspension, a sliding plate is slidably connected to the fixing plate, a tensioning rod is fixedly connected to the fixing plate, and connecting plates are fixedly connected to both sides of the tool rest.

[0014] The beneficial effects of the present utility model are as follows: By arranging a scraping plate on the side of the scraping knife where materials are attached, and then driving the scraping plate to reciprocate back and forth on the side of the scraping knife through a driving component. When the scraping plate reciprocates and cleans the materials attached to the scraping knife, with the cooperation of a water spraying tank, a water pump, and a water spraying nozzle, the materials scraped by the scraping plate are humidified and subjected to water flow impact, accelerating the speed at which the scraping plate scrapes off the materials. During this process, the materials attached to the scraping knife will be scraped off by the scraping plate, keeping the scraping knife in a certain degree of cleanliness and avoiding affecting the scraping and cleaning effect on the belt conveyor body due to the attachment of materials on the scraping knife.

[0023] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific illustrations.

[0024] Referring to Figures 1-6 As shown, the cleaning device at the head of the belt conveyor includes the belt conveyor body 1, and the surface of the belt conveyor body 1 for transporting materials is the transport surface of the belt conveyor body 1. Suspensions 2 are installed on both sides of the discharge end of the belt conveyor body 1, and a scraper 3 is connected to the suspensions 2. The scraper 3 is generally made of latex material. The purpose is to better contact between one end of the scraper 3 and the transport surface of the belt conveyor body 1 to improve the cleaning efficiency. The used end of the scraper 3 is the output end of the scraper 3, that is, the blade of the scraper 3. The scraper 3 is located below the belt conveyor body 1, and the output end of the scraper 3 is in contact with the transport surface of the belt conveyor body 1. After the belt conveyor body 1 discharges materials, the scraper 3 will scrape and clean the transport surface of the belt conveyor body 1 after discharging. A tool rest 8 is rotatably connected to the suspension 2, and the other end of the scraper 3 is fixedly installed on the tool rest 8. The tool rest 8 facilitates the use and installation of the scraper 3, and the use of the tool rest 8 ensures that the scraper 3 is more stable during use.

[0025] When the scraper 3 scrapes the transport surface of the belt conveyor body 1, since the scraper 3 is located below the belt conveyor body 1, the materials will fall along the side of the scraper 3. However, a part of the materials will adhere to the side of the scraper 3. Over time, it will be difficult to remove and adhere to the scraper 3, and it will affect the cleaning operation of the scraper 3 on the transport surface of the belt conveyor body 1. Therefore, a scraping plate 4 is provided on one side of the scraper 3 close to the discharge end of the belt conveyor body 1, and the scraping plate 4 is in close contact with the side of the scraper 3. A driving component 5 for driving the scraping plate 4 to reciprocate on the surface of the scraper 3 is provided on the suspension 2. A water spray tank 6 connected to a water pump 7 is provided on the side of the scraper 3 close to the scraping plate 4, and the output end of the water spray tank 6 faces the contact surface between the scraper 3 and the scraping plate 4. When the scraping plate 4 is in use, the driving component 5 drives the scraping plate 4 to reciprocate on the side of the scraper 3. During the movement, the materials adhering to the scraper 3 will be scraped towards both sides. And during the scraping process, water is sprayed from the water spray tank 6 to the contact surface between the scraper 3 and the scraping plate 4. Under the impact of the water flow, the scraping and cleaning effect of the scraping plate 4 on the side of the scraper 3 is enhanced. And when there is water flow between the scraping plate 4 and the scraper 3, the mutual friction force between the scraper 3, the scraping plate 4 and the materials will also be reduced, reducing the damage to the scraper 3.

[0026] In order to ensure that when the scraper 4 scrapes off the material on the side of the blade 3, the material can be collected, a drainage box 9 is fixedly connected to the tool rest 8, and the input end of the drainage box 9 is located at the side position of the blade 3 close to the scraper 4. When the drainage box 9 is in use, its output end can be connected to other material recovery devices (not shown in the figure). Then, two baffles 18 are fixedly connected to the tool rest 8, and the two baffles 18 are respectively located on both sides of the blade 3. At this time, the material scraped to both sides of the blade 3 by the scraper 4 will accumulate together under the action of the baffles 18, and then under the impact of water flow and the action of gravity, it will gradually flow into the drainage box 9. The advantage of the drainage box 9 receiving the material from the side of the blade 3 is that it reduces the impact of the material driven by the scraping of the scraper 4 on the surrounding environment and is more convenient for processing the material.

[0027] Among them, referring to Figure 3 and Figure 6 as shown, the driving assembly 5 includes a threaded rod 501 rotatably connected to the tool rest 8, a first pulley 502 fixedly connected to one end of the threaded rod 501, a second pulley 503 fixedly connected to the tool rest 8, a transmission belt 504 sleeved on the first pulley 502 and the second pulley 503, and a motor 505 connected to the drainage box 9. The threaded rod 501 is threadedly connected to the scraper 4, and the output end of the motor 505 is connected to the second pulley 503. When the motor 505 operates, its output end drives the second pulley 503 to rotate, and then drives the first pulley 502 to rotate through the transmission belt 504. When the first pulley rotates, it will drive the threaded rod 501 to rotate on the tool rest 8, and the threaded rod 501 will drive the scraper 4 threadedly connected to it to move. Among them, when the threaded rod 501 rotates in a clockwise direction repeatedly, it drives the scraper 4 to move back and forth on the blade 3. When the threaded rod 501 drives the scraper 4 to move, in order to ensure the stability of the scraper 4 during movement, a sliding rod 11 corresponding to the position of the threaded rod 501 is fixedly connected to the tool rest 8, and the scraper 4 is slidably connected to the sliding rod 11. When the scraper 4 moves, it will move along the axis direction of the sliding rod 11.

[0028] Referring to Figure 3 and Figure 5As shown in the figure, further, the water spraying tank 6 is fixedly connected to the tool rest 8, and the water spraying tank 6 is composed of a box body 601 and a water spraying nozzle 602. A water guide pipe 10 is communicated between the input end of the box body 601 and the output end of the water pump 7. The water pump 7 is installed on the suspension 2. The water spraying nozzle 602 is communicated with the output end of the box body 601. The output direction of the water spraying nozzle 602 faces the contact surface between the scraping knife 3 and the scraping plate 4. During use, the input end of the water pump 7 accesses the external water source, and then through the pressurized transportation of the water pump 7, the water flow is introduced into the interior of the box body 601 through the water guide pipe 10, and then sprayed out from the water spraying nozzle 602 on the box body 601. According to the actual use, the number and position of the water spraying are reasonably installed, and the output direction of the water spraying nozzle 602 can also be changed according to the actual use situation.

[0029] Furthermore, referring to Figures 3-4 As shown in the figure, in order to protect the transportation surface of the belt conveyor body 1 when the scraping knife 3 scrapes the transportation surface of the belt conveyor body 1, it is necessary to make the positional relationship between the scraping knife 3 and the transportation surface of the belt conveyor body 1 not fixed. When the belt conveyor body 1 is running, its transportation surface will inevitably fluctuate. If the positional relationship between the two is fixed, the output end of the scraping knife 3 will damage the transportation surface when the transportation surface of the belt conveyor body 1 fluctuates. Secondly, the scraping knife 3 itself will also be damaged. Therefore, a fixing plate 12 is fixedly connected to the suspension 2, a sliding plate 13 is slidably connected to the fixing plate 12, a tensioning rod 14 is fixedly connected to the fixing plate 12, connecting plates 15 are fixedly connected to both sides of the tool rest 8, the tensioning rod 14 passes through the connecting plates 15 and the sliding plate 13, and the tensioning rod 14 is in movable contact with the connecting plates 15 and the sliding plate 13, that is, the connecting plate 15 can swing on the tensioning rod 14. The purpose is that when the connecting plate 15 deflects along with the scraping knife 3, the tensioning rod 14 will not restrict the connecting plate 15. At this time, the positional relationship between the connecting plate 15 connected to the tool rest 8 and the fixing plate 12 on the suspension 2 is not fixed. When the scraping knife 3 vibrates, the connecting plate 15 can make a corresponding offset to relieve the vibration of the scraping knife 3.

[0030] In order to make the offset of the connecting plate 15 more elastic and stable, a spring 16 is fixedly connected between the connecting plate 15 and the sliding plate 13. A threaded portion 141 is provided at one end of the tightening rod 14 away from the fixed plate 12. A fastener 17 is movably threadedly connected through one end of the sliding plate 13. The fastening frame is located at the side position of the sliding plate 13 away from the fixed plate 12. The fastener 17 is threadedly connected to the threaded portion 141. The main purpose is to rotate on the threaded portion 141 to thereby squeeze the sliding plate 13. By the squeezing degree of the sliding plate 13 by the fastener 17, the elastic force of the spring 16 is adjusted, and then the vibration amplitude of the scraper 3 is adjusted. When this structure is in use, the vibration of the scraper 3 causes the connecting plate 15 to vibrate accordingly. Under the action of the tightening rod 14, the offset of the connecting plate 15 is limited within a certain range, and the vibration offset of the connecting plate 15 will cause the spring 16 to deform. Under the action of the elastic force of the spring 16, the connecting plate 15 will shake smoothly. After the shaking stops, it will return to the initial position. The connecting plate 15 and the scraper 3 deflect and move synchronously, so that the distance between the scraper 3 and the conveying surface of the belt conveyor body 1 will move according to the actual use situation, reducing the damage of the scraper 3 to the conveying surface of the belt conveyor body 1, thereby protecting the conveying surface of the belt conveyor body 1 and extending the service life of the equipment.
