Description

Technical Field

[0001] This utility model relates to the field of scraper cleaning technology, and in particular to a scraper cleaning device for scraper machines. Background Technology

[0002] A scraper conveyor is a type of mechanical equipment commonly used in industrial production, primarily for conveying, cleaning, or processing solid materials. Its working principle is similar to a chain drive system; the scraper conveyor uses a chain or belt drive system, in conjunction with scrapers fixed to the chain, to achieve the conveying or cleaning of materials.

[0003] During normal operation of a scraper conveyor, the scraper blades are constantly in contact with materials. Some materials tend to adhere to and accumulate on the scraper surface. If not cleaned in time, this dirt will cause the scraper surface to become rough, increasing friction and thus accelerating scraper wear, affecting the normal operation of the equipment. Since the height of scraper conveyors varies, if the height of the cleaning device is fixed, the distance between the nozzle and the scraper cannot be adjusted according to the scraper height or changes in different working conditions. This can easily lead to some areas being over-cleaned while other areas are not effectively cleaned, affecting the cleaning effect and adaptability. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a scraper cleaning device for scraper machines, which aims to improve the problem of uneven cleaning effect caused by the inability to adjust the height of scraper machines.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A scraper cleaning device for a scraper conveyor includes a base plate, a fixing plate fixedly connected to the upper surface of the base plate, a frame fixedly connected to the upper surface of the fixing plate, a crank handle rotatably connected inside the frame, a worm gear fixedly connected to the outer wall of the crank handle, a worm wheel meshing with the tooth end of the worm gear, a sleeve fixedly connected inside the worm wheel, the outer wall of the sleeve rotatably connected to the inner wall of the fixing plate, a lead screw threaded inside the sleeve, a sliding frame fixedly connected to the upper surface of the lead screw, the inner wall of the sliding frame slidably connected to the outer wall of the fixing plate, and a conveying assembly disposed on the upper surface of the sliding frame for conveying water.

[0007] Preferably, the conveying assembly includes a lifting plate, the lower surface of which is fixedly connected to the upper surface of the sliding frame, a water pump fixedly connected to the upper surface of the lifting plate, a water tank fixedly connected to the input end of the water pump, and a hose fixedly connected to the output end of the water pump.

[0008] Preferably, a second fixing plate is fixedly connected to the upper surface of the lifting plate, and a motor is fixedly connected to the outer wall of the second fixing plate.

[0009] Preferably, a turntable is fixedly installed at the output end of the motor.

[0010] Preferably, a fixed column is fixedly connected to the outer wall of the turntable, and a transmission plate is rotatably connected to the outer wall of the fixed column.

[0011] Preferably, a U-shaped block is rotatably connected to the outer wall of the transmission plate, and a sliding plate is fixedly connected to the lower surface of the U-shaped block.

[0012] Preferably, the sliding plate is internally slidably connected to a slide rail, the lower surface of the slide rail is fixedly connected to the upper surface of the lifting plate, and a high-pressure nozzle is fixedly connected to the upper surface of the sliding plate.

[0013] Preferably, the outer wall of the hose is disposed on the outer wall of the high-pressure nozzle.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, rotating the crank handle causes it to drive the worm gear to rotate, which in turn drives the sleeve to rotate on the inner wall of the fixed plate. The sleeve then drives the lead screw to slide up and down, ultimately causing the sliding frame and the lifting plate to slide up and down, adjusting the height so that the cleaning device always matches the height of the scraper machine, thus improving the adaptability.

[0016] 2. In this utility model, the motor is turned on, causing the fixed column to rotate via the turntable. This, in turn, causes the U-shaped block to slide via the transmission plate, which in turn causes the high-pressure nozzle to slide back and forth via the sliding plate. This ensures that each area receives a uniform high-pressure water flow impact, improving the uniformity of cleaning. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a scraper cleaning device for a scraper machine, comprising a base plate 1, a fixed plate 2 fixedly connected to the upper surface of the base plate 1, a frame 3 fixedly connected to the upper surface of the fixed plate 2, a crank handle 4 rotatably connected inside the frame 3, a worm gear 5 fixedly connected to the outer wall of the crank handle 4, a worm wheel 6 meshing with the tooth end of the worm gear 5, a sleeve 7 fixedly connected inside the worm wheel 6, the outer wall of the sleeve 7 rotatably connected to the inner wall of the fixed plate 2, a lead screw 8 threadedly connected inside the sleeve 7, a sliding frame 9 fixedly connected to the upper surface of the lead screw 8, the inner wall of the sliding frame 9 slidably connected to the outer wall of the fixed plate 2, and a conveying component provided on the upper surface of the sliding frame 9 for conveying water.

[0024] Specifically, the base plate 1 provides fixed support for the fixed plate 2, which in turn provides fixed support for the frame 3. The frame 3, in turn, supports the crank handle 4. When the crank handle 4 is turned, it drives the worm gear 5 to rotate, which in turn drives the worm wheel 6 to rotate. The rotation of the worm wheel 6 then drives the sleeve 7 to rotate. Since the sliding frame 9 fixes the lead screw 8, when the sleeve 7 rotates, it causes the lead screw 8 to slide up and down. This sliding of the lead screw 8, in turn, causes the sliding frame 9 to move up and down on the outer wall of the fixed plate 2, thus adjusting the height. This allows the cleaning device to adjust its height according to the height of the scraper, ensuring a suitable distance between the cleaning device and the scraper surface for optimal cleaning. It prevents ineffective cleaning of certain areas of the scraper due to an unsuitable height, ensuring optimal cleaning results even with different scraper heights and improving adaptability.

[0025] Reference Figure 1 andFigure 3 The conveying assembly includes a lifting plate 10, the lower surface of the lifting plate 10 is fixedly connected to the upper surface of the sliding frame 9, a water pump 12 is fixedly connected to the upper surface of the lifting plate 10, a water tank 11 is fixedly connected to the input end of the water pump 12, and a hose 13 is fixedly connected to the output end of the water pump 12.

[0026] Specifically, the sliding frame 9 can provide fixed support for the lifting plate 10. When the sliding frame 9 moves up and down, it will also drive the lifting plate 10 to move up and down. The lifting plate 10 can also provide fixed support for the water tank 11 and the water pump 12. The water pump 12 can deliver the water inside the water tank 11 to the hose 13, and then deliver it to the high-pressure nozzle 22 through the hose 13, so that the high-pressure nozzle 22 can use this water to perform high-pressure rinsing on the scraper.

[0027] Reference Figure 3 A fixed plate 14 is fixedly connected to the upper surface of the lifting plate 10, and a motor 15 is fixedly connected to the outer wall of the fixed plate 14. A turntable 16 is fixedly installed at the output end of the motor 15. A fixed column 17 is fixedly connected to the outer wall of the turntable 16, and a transmission plate 18 is rotatably connected to the outer wall of the fixed column 17. A U-shaped block 19 is rotatably connected to the outer wall of the transmission plate 18, and a sliding plate 20 is fixedly connected to the lower surface of the U-shaped block 19. A slide rail 21 is slidably connected inside the sliding plate 20, and the lower surface of the slide rail 21 is fixedly connected to the upper surface of the lifting plate 10. A high-pressure nozzle 22 is fixedly connected to the upper surface of the sliding plate 20. The outer wall of the hose 13 is set on the outer wall of the high-pressure nozzle 22.

[0028] Specifically, the lifting plate 10 provides fixed support for the fixed plate 14, which in turn provides fixed support for the motor 15. When the motor 15 is turned on, it drives the turntable 16 to rotate. The rotation of the turntable 16 drives the fixed column 17 to rotate around the turntable 16, and the rotation of the fixed column 17 also drives the transmission plate 18 to rotate. At the same time, the rotation of the transmission plate 18 pushes the U-shaped block 19 to slide, and the sliding of the U-shaped block 19 also drives the sliding plate 20 to slide on the outer wall of the slide rail 21. The lifting plate 10 provides fixed support for the slide rail 21, and the slide rail 21 supports the sliding plate 20, ensuring the stability of the sliding plate 20. The sliding of the sliding plate 20 also drives the high-pressure nozzle 22 to slide back and forth, so that the high-pressure nozzle 22 washes the scraper back and forth, ensuring that the high-pressure water flow is evenly distributed on the surface of the scraper and preventing some areas from being missed. The repeated movement of the nozzles ensures that each area receives a uniform high-pressure water flow, thereby removing dirt and improving the uniformity of cleaning.

[0029] Working principle: When the device is needed, first place it at the inlet and outlet of the scraper conveyor. Then, turn the crank handle 4 to drive the worm gear 5 to rotate. The rotation of the worm gear 5 will drive the worm wheel 6 to rotate, and the rotation of the worm wheel 6 will also drive the sleeve 7 to rotate on the inner wall of the fixed plate 2. At the same time, the rotation of the sleeve 7 will drive the lead screw 8 to slide up and down. The up and down sliding of the lead screw 8 will drive the sliding frame 9 to slide up and down on the outer wall of the fixed plate 2, and the sliding of the sliding frame 9 will drive the lifting plate 10 to slide up and down, so that the height of the cleaning device can be adjusted according to the height of the scraper conveyor. Then, start the water pump 12 to deliver the water in the water tank 11 to the high-pressure nozzle 22 through the hose 13. Then, start the motor 15 to drive the high-pressure nozzle 22. The rotating turntable 16 rotates, which in turn drives the fixed column 17 to rotate. The rotation of the fixed column 17 also drives the transmission plate 18 to rotate. Simultaneously, the rotation of the transmission plate 18 drives the U-shaped block 19 to slide. The sliding of the U-shaped block 19 also drives the sliding plate 20 to slide at the slide rail 21, thereby driving the high-pressure nozzle 22 to slide. This allows the high-pressure nozzle 22 to perform reciprocating and uniform sliding cleaning. In other words, this device can not only adjust the height of the lifting plate 10 to adapt to different scraper heights and ensure that the cleaning device and the scraper surface always maintain a suitable distance to achieve the best cleaning effect and improve adaptability, but also ensure that each area receives a uniform high-pressure water flow impact by allowing the high-pressure nozzle 22 to slide back and forth, thus improving the cleaning uniformity.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
