Description

Technical Field

[0001] This utility model belongs to the field of mining equipment technology, and in particular relates to a conveyor device for cleaning and conveying accumulated material at the bottom of a belt conveyor. Background Technology

[0002] Belt conveyors are a common type of continuous conveying equipment. They consist of a conveyor belt, a drive unit, idlers, and a frame. The conveyor belt is wrapped around the drive unit and idlers, and the drive unit drives the conveyor belt to run. They can efficiently transport various bulk materials or packaged goods and are widely used in industries such as mining, ports, chemicals, and power. They have the advantages of large conveying capacity and stable operation.

[0003] The existing scrapers used by belt conveyors to clean the accumulated material at the bottom of the belt conveyor are not easy to move. This may make it impossible to adjust the distance between the scraper and the belt in a timely manner according to the material accumulation. As a result, the scraper may be too far away, resulting in incomplete cleaning, or too close, resulting in increased wear on the scraper and the belt, and shortening the service life of the scraper and the belt. Utility Model Content

[0004] The purpose of this utility model is to provide a conveyor device for cleaning accumulated material at the bottom of a belt conveyor. By providing a cleaning mechanism, it solves the problem that the scraper used in existing belt conveyor devices for cleaning accumulated material at the bottom of the belt conveyor is not easy to move.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a device for cleaning and conveying accumulated material at the bottom of a belt conveyor, comprising a base plate, on which a cleaning mechanism and a vibration mechanism are provided.

[0007] The cleaning mechanism includes a moving component and a transmission component. The moving component includes a belt conveyor fixedly connected to the top of the base plate. A threaded rod is rotatably connected between the top of the base plate and the belt conveyor. An internal threaded block is threaded onto the threaded rod. A sliding rod is fixedly connected between the top of the base plate and the belt conveyor. A slider is slidably connected onto the sliding rod. A scraper is fixedly connected between the slider and the internal threaded block.

[0008] Furthermore, a transfer box is fixedly connected to the bottom of the belt conveyor, and a filter plate is fixedly connected to the inner wall of the transfer box. The threaded rod and the sliding rod both pass through the transfer box and the filter plate. The threaded rod is rotatably connected to the transfer box and the filter plate, and the sliding rod is fixedly connected to the transfer box and the filter plate.

[0009] Furthermore, the transmission assembly includes a conveying cylinder fixedly connected to the top of the base plate, and a connecting pipe is fixedly connected between the transfer box and the conveying cylinder.

[0010] Furthermore, a motor is fixedly connected to the top of the base plate, and the output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The left end of the rotating shaft extends into the interior of the conveying cylinder and is rotatably connected to the conveying cylinder. A spiral blade is fixedly connected to the rotating shaft, and the spiral blade is slidably connected to the inner wall of the conveying cylinder.

[0011] Furthermore, a collection box is fixedly connected to the top of the base plate, the left end of the conveying cylinder extends into the interior of the collection box and is fixedly connected to the collection box, a sealing door is provided on the front side of the collection box, and a material handling door is provided on the right side of the transfer box.

[0012] Furthermore, the vibration mechanism includes a second motor fixedly connected to the top of the base plate. The output shaft of the second motor is fixedly connected to a second rotating shaft via a coupling. Each threaded rod of the second rotating shaft is fixedly connected to a pulley, and a belt is sleeved between the two pulleys.

[0013] Furthermore, a connecting plate is hinged to the left side of the transfer box, a vibrating hammer is fixedly connected to the right side of the connecting plate, and a wedge block is fixedly connected to the right side of the connecting plate.

[0014] Furthermore, a cam is fixedly connected to the top of the second rotating shaft, and a telescopic rod is hinged between the left side of the connecting plate and the bottom of the belt conveyor, with a spring sleeved on the telescopic rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting up a cleaning mechanism, the rotation of the threaded rod drives the internal threaded block to move, which in turn drives the scraper to move. The scraper then drives the slider to slide on the slide rod. The accumulated material enters the conveyor cylinder from the transfer box and connecting pipe. The motor is started, which drives the rotating shaft to rotate. The rotating shaft then drives the spiral blades to rotate. The cleaning mechanism adjusts the distance between the scraper and the belt to ensure that the scraper can closely adhere to material layers of different thicknesses, thereby more effectively scraping away the accumulated material. This avoids the scraper being too close to the belt, which could cause excessive pressure on the scraper and damage the scraper or belt. Maintaining a suitable relative distance between the scraper and the belt can enhance the scraping force, ensuring that the accumulated material is thoroughly cleaned while also preventing excessive wear on the scraper and extending its service life.

[0017] 2. By setting up a vibration mechanism, starting motor two, motor two drives shaft two to rotate. When shaft two rotates, it drives the threaded rod to rotate through the pulley and belt. When shaft two rotates, it drives the cam to rotate. When the cam rotates and contacts the inclined block, it applies a thrust to the inclined block, which in turn causes the inclined block to move the connecting plate. When the connecting plate moves, it drives the vibrating hammer to move. When the connecting plate moves, it causes the telescopic rod and spring to retract. Through the vibration mechanism, the accumulated material and impurities on the filter plate are continuously vibrated and impacted, which loosens them and prevents impurities from clogging the filter holes. This ensures that the filter plate always maintains a good filtration state and avoids the accumulation of material and impurities clogging the filter plate at the filter holes, thus reducing the filtration efficiency of the filter plate. At the same time, the filter plate always maintains a certain degree of activity under the vibration, reducing the possibility of accumulated material and impurities adhering to the filter plate for a long time and forming stubborn clumps. This greatly reduces the difficulty of cleaning the filter plate.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5As shown, this utility model is a conveyor device for cleaning and conveying accumulated material at the bottom of a belt conveyor. It includes a base plate 1, on which a cleaning mechanism 2 and a vibration mechanism 3 are mounted. The cleaning mechanism 2 includes a moving component and a transmission component. The moving component includes a belt conveyor 21 fixedly connected to the top of the base plate 1. A threaded rod 22 is rotatably connected between the top of the base plate 1 and the belt conveyor 21. An internal threaded block 23 is threaded onto the threaded rod 22. A sliding rod 24 is fixedly connected between the top of the base plate 1 and the belt conveyor 21. A slider 25 is slidably connected to the sliding rod 24. A scraper 26 is fixedly connected between the slider 25 and the internal threaded block 23. A transfer box 27 is fixedly connected to the bottom of the belt conveyor 21. A filter plate 28 is fixedly connected to the inner wall of the transfer box 27. A threaded rod 22 and a sliding rod 24 both pass through the transfer box 27 and the filter plate 28. The threaded rod 22 is rotatably connected to the transfer box 27 and the filter plate 28, and the sliding rod 24 is fixedly connected to the transfer box 27 and the filter plate 28. The transmission assembly includes a conveying cylinder 29 fixedly connected to the top of the base plate 1. A connecting pipe 2 is fixedly connected between the transfer box 27 and the conveying cylinder 29. 10. A motor 211 is fixedly connected to the top of the base plate 1. The output shaft of the motor 211 is fixedly connected to a rotating shaft 212 via a coupling. The left end of the rotating shaft 212 extends into the interior of the conveying cylinder 29 and is rotatably connected to the conveying cylinder 29. A spiral blade 213 is fixedly connected to the rotating shaft 212 and is slidably connected to the inner wall of the conveying cylinder 29. A collection box 214 is fixedly connected to the top of the base plate 1. The left end of the conveying cylinder 29 extends into the interior of the collection box 214 and is fixedly connected to the collection box 214. A sealing door 215 is provided on the front side of the collection box 214, and a material handling door 216 is provided on the right side of the transfer box 27. The distance between the scraper 26 and the belt is adjusted by the cleaning mechanism 2 to ensure that the scraper can closely fit the material layers of different thicknesses, thereby more effectively scraping off the accumulated material and avoiding the scraper 26 being too close to the belt, which would cause the scraper 26 to be over-pressed and damaged. At the same time, the scraped accumulated material is concentrated and transported to the collection box 214 for subsequent processing.

[0029] The vibration mechanism 3 includes a second motor 31 fixedly connected to the top of the base plate 1. The output shaft of the second motor 31 is fixedly connected to a second rotating shaft 32 via a coupling. Pulleys 33 are fixedly connected to the threaded rod 22 of the second rotating shaft 32. A belt 34 is sleeved between the two pulleys 33. A connecting plate 35 is hinged to the left side of the transfer box 27. A vibrating hammer 36 is fixedly connected to the right side of the connecting plate 35. A wedge block 37 is fixedly connected to the right side of the connecting plate 35. A cam 38 is fixedly connected to the top of the second rotating shaft 32. The left side of the connecting plate 35 is hinged to the bottom of the belt conveyor 21. A telescopic rod 39 is provided, and a spring 310 is fitted on the telescopic rod 39. The vibration mechanism 3 causes the accumulated material and impurities on the filter plate 28 to be continuously vibrated and impacted, which loosens them and prevents impurities from clogging the filter holes. This ensures that the filter plate 28 always maintains a good filtration state, avoids the accumulation of material and impurities clogging the filter plate 28 at the filter holes, and avoids reducing the filtration efficiency of the filter plate 28. At the same time, it makes the filter plate 28 maintain a certain degree of activity under the action of vibration, reducing the possibility of accumulated material and impurities adhering to the filter plate 28 for a long time and forming stubborn clumps. This greatly reduces the difficulty of cleaning the filter plate 28.

[0030] A specific application of this embodiment is as follows: Starting motor 31 drives shaft 32 to rotate. When shaft 32 rotates, it drives threaded rod 22 to rotate via pulley 33 and belt 34. The rotation of threaded rod 22 causes internal threaded block 23 to move. The movement of internal threaded block 23 causes scraper 26 to move. The movement of scraper 26 causes slider 25 to slide on slide bar 24. Slider 25 limits the internal threaded block 23, converting its rotational motion into linear motion. Scraper 26 cleans the accumulated material at the bottom of conveyor belt 21. Simultaneously, the distance between scraper 26 and the bottom of conveyor belt 21 is adjusted to ensure that scraper 26 can closely adhere to material layers of different thicknesses, thereby more effectively scraping off the accumulated material. The accumulated material falls into the interior of the transfer box 27, and then through the connecting pipe 210 into the interior of the conveying cylinder 29. The accumulated material inside the transfer box 27 is screened and filtered by the filter plate 28 to prevent large-volume accumulated material from clogging subsequent equipment and damaging the spiral blades 213 inside the conveying cylinder 29. The material that has not passed through the filter plate 28 can be removed through the material removal door 216 for subsequent processing. The motor 211 is started, and the motor 211 drives the rotating shaft 212 to rotate. When the rotating shaft 212 rotates, it drives the spiral blades 213 to rotate, and then the spiral blades 213 transport the accumulated material that has fallen into the conveying cylinder 29 to the collection box 214. Finally, the accumulated material in the collection box 214 is removed through the sealing door 215 for centralized processing.

[0031] When the rotating shaft 32 rotates, it drives the cam 38 to rotate. When the cam 38 rotates and contacts the inclined block 37, it applies a pushing force to the inclined block 37, which in turn causes the inclined block 37 to move the connecting plate 35. When the connecting plate 35 moves, it drives the vibrating hammer 36 to move. When the connecting plate 35 moves, it causes the telescopic rod 39 and the spring 310 to retract. When the inclined block 37 is no longer in contact with the cam 38, the cam 38 no longer applies a pushing force to the inclined block 37, which in turn causes the connecting plate 35 to no longer be under force. Therefore, the telescopic rod 39 and the spring 310 reset, which in turn causes the vibrating hammer 36 to contact the transfer box 27 and apply an impact force to the transfer box 27, causing the transfer box 27 to vibrate. The vibration of the transfer box 27 is transmitted to the filter plate 28. The vibration of the filter plate 28 loosens the accumulated material on the filter plate 28, allowing it to pass through the filter plate 28 quickly and preventing the accumulated material from accumulating on the filter plate 28 and causing the filter holes to become blocked, thus affecting the material's throughput.
