It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0023] Example:

[0024] like Figure 1-Figure 12As shown, a reduction gear internal circulation cleaning mechanism comprises a body 1, a cleaning box 2 is installed on one side of the body 1, an oil filling pump 3 and an oil extraction pump 4 are respectively arranged on both sides of the top of the cleaning box 2 and are respectively connected to the oil filling port and the oil outlet of the body 1 through pipelines, a filter box 5 and a collection box 6 are sequentially installed inside the cleaning box 2, the bottom of the filter box 5 is connected to the collection box 6 through a filter plate 10, and the filter box 5 is connected to the oil extraction pump 4 through a pipeline, which can realize the circulation operation of the cleaning liquid inside the reduction gear, and then realize the circulation cleaning operation, a magnetic rod 14 is arranged throughout the filter box 5, and the magnetic rod 14 is a permanent magnet metal rod, which absorbs magnetic metal debris inside the cleaning liquid and prevents the metal debris from gathering inside the cleaning liquid, To improve the cleaning effect, the collection box 6 is connected to the oil injection pump 3 through a pipeline, a filter cartridge 11 is arranged inside the filter cartridge 5, and an oil return port 12 is arranged on the filter cartridge 11. The oil return port 12 is connected to the oil pump 4 through a pipeline, and the cleaning liquid extracted from the reducer can be introduced into the filter cartridge 11. A magnetic filtering mechanism is arranged between the filter cartridge 11 and the filter cartridge 5, and a collection box 8 is installed at the bottom of both sides of the filter cartridge 5. A baffle 16 is movably arranged on one side where the collection box 8 is connected to the filter cartridge 5, and an impurity accumulation mechanism is also arranged between the filter cartridge 11 and the filter cartridge 5 through the magnetic filtering mechanism, which can accumulate the adsorbed and filtered magnetic debris and impurities, etc., for convenience of subsequent processing, wherein: A magnetic filtering mechanism is configured to absorb magnetic impurities that enter the filter cartridge 11 so that the magnetic impurities are absorbed on the magnetic rod 14 to prevent magnetic debris from gathering and accumulating in the cleaning liquid; The impurity accumulation mechanism is configured to concentrate and accumulate the magnetic impurities adsorbed inside the filter cartridge 11 and the impurities filtered by the filter plate 10, so as to facilitate subsequent removal, reduce the difficulty of subsequent cleaning of the impurities, and prevent the impurities from accumulating inside the cleaning device to affect the cleaning operation.

[0025] In this embodiment, the magnetic filtering mechanism includes a collecting cylinder 7 and a reinforcing sleeve 22. The collecting cylinder 7 is installed at both ends of the filter box 5, and the inside of the collecting cylinder 7 is connected to the filter box 5. The two ends of the magnetic rod 14 are respectively connected to the bottom of the collecting cylinder 7 at both ends of the filter box 5. The reinforcing sleeve 22 is installed at the connection between the two ends of the filter cylinder 11 and the magnetic rod 14, and the magnetic impurities are adsorbed by the magnetic rod 14. And the impurities are received by the collecting cylinder 7.

[0026] Specifically, the reinforcing sleeve 22 is an elastic rubber sleeve, and a plurality of support columns 27 are circumferentially arranged on the inner wall of the reinforcing sleeve 22, and a pad 28 is installed at the other end of the support column 27, so as to reduce the degree of scraping of impurities adsorbed on the magnetic rod 14 when the filter cylinder 11 is adjusted to move left and right, thereby improving the maximum removal effect of impurities.

[0027] In this embodiment, the impurity accumulation mechanism drives the motor 9, the guide stud 17, the guide seat 23, the first shielding film 13, the second shielding film 19, the sliding ring 15 and the push plate 18. The guide seat 23 is installed on the opposite sides of the filter cartridge 11. The cross-section of the guide seat 23 is an arc-shaped structure, and the inner wall of the guide seat 23 is engraved with threads. The guide stud 17 is rotatably arranged on both sides of the inside of the filter box 5, and the drive motor 9 is installed at one end of the filter box 5, and the output end of the drive motor 9 extends into the inside of the filter box 5 and is connected to the guide stud 17 on one side of the inside of the filter box 5, and the position of the guide stud 17 corresponds to the position of the guide seat 23. By rotating the guide stud 17, the guide seat 23 can be driven to drive the filter cartridge 11 moves inside the filter box 5, and the sliding ring 15 is slidably arranged on the two ends of the magnetic rod 14 located on the outside of the filter cylinder 11. The sliding ring 15 is provided with a scraper unit, which can remove the magnetic impurities adsorbed on the magnetic rod 14 and make them accumulate. One end of the first shielding film 13 is installed on the side wall of the end of the filter cylinder 11, and the other end is installed on the side wall of the sliding ring 15. One end of the second shielding film 19 is installed on the side wall of the collecting cylinder 7, and the other end is installed on the side wall of the sliding ring 15. The push plate 18 is slidably arranged on the filter box 5 through an anti-detachment mechanism to prevent the push plate 18 from detaching. The bottom of the push plate 18 is tangent to the filter plate 10, and can push the impurities filtered on the filter plate 10.

[0028] Specifically, the first shielding film 13 and the second shielding film 19 are both elastic films, and both sides of the first shielding film 13 and the second shielding film 19 are treated with anti-corrosion. The setting of the first shielding film 13 and the second shielding film 19 prevents the scraped magnetic impurities from diffusing inside the filter cartridge 11, thereby facilitating the accumulation treatment of the magnetic impurities.

[0029] In this embodiment, the scraper unit includes a guide sleeve 21, which is installed on the inner wall of the sliding ring 15, and the cross-section of the guide sleeve 21 is a conical structure, and the lower inclined end of the guide sleeve 21 cross-section faces the direction of the first shielding film 13 connected to the sliding ring 15, and the bottom of the upper inclined end of the guide sleeve 21 does not contact the magnetic rod 14. As the filter cylinder 11 moves along the guide stud 17, the magnetic impurities adsorbed on the magnetic rod 14 in the forward direction of the guide sleeve 21 are hung by the inclined bottom of the guide sleeve 21, so that they fall into the area between the second shielding film 19 and the collecting cylinder 7, and as the filter cylinder 11 continues to move, they eventually fall into the inside of the collecting cylinder 7, which is convenient for subsequent cleaning and processing.

[0030] In this embodiment, the anti-slip mechanism includes a slide groove 20, a socket 24 and a limit groove 29. The slide groove 20 is opened in the middle of the push plate 18, and the limit grooves 29 are opened at both ends of the push plate 18. The position of the limit groove 29 corresponds to the position of the guide stud 17, and the limit groove 29 is engraved with threads, and the guide stud 17 is meshed with the inner wall threads of the limit groove 29. The socket 24 is installed at both ends of the push plate 18, and the side opposite to the limit groove 29 of the socket 24 is an arc structure, and the arc side of the socket 24 is engraved with threads, and the threads of the socket 24 are meshed with the threads of the guide stud 17, and the height of the socket 24 is higher than the height of the guide seat 23. The socket 24 cooperates with the arc structure between the limit grooves 29 to complete the limitation of the push plate 18, which not only makes the push plate 18 move with the rotation of the guide stud 17, but also prevents the push plate 18 from tipping over or disengaging from the rotation of the guide stud 17 during movement.

[0031] Specifically, the arcs among the holder 24, the guide seat 23 and the limit groove 29 are the same, ensuring the precise adjustment drive of the device by the rotation of the guide stud 17. An elastic rubber plate is installed at the junction of the guide seat 23 and the filter cartridge 11. When the end of the filter cartridge 11 is connected to the side wall of the filter box 5, the continued rotation of the guide stud 17 can force the guide seat 23 to contract, so that the rotation of the guide stud 17 continues to push the push plate 18 to move, thereby completing the push and accumulation of impurities.

[0032] Specifically, a baffle 16 is rotatably installed on one side of the collection box 8 connected to the filter box 5, and support rods 25 are installed at both ends of the baffle 16 facing the filter box 5. The bottom of the support rod 25 is an arc structure, so that the push plate 18 first contacts the support rod 25 when moving, pushing the baffle 16 to rotate inward, so that impurities and the like enter the interior of the collection box 8, which is convenient for removing the device.

[0033] Specifically, the top of the baffle 16 is rotatably hinged to the collection box 8, and a pad 16 is installed at the bottom of the baffle 16, and the arc of the arc structure at the bottom of the support rod 25 is the same as the arc of the rotation trajectory of the baffle 16, thereby improving the sealing of the collection box 8, reducing the overflow of the cleaning liquid, and preventing the movement of the baffle 16 from being damaged.

[0034] Specifically, limit springs 26 are obliquely arranged at both ends of the side opposite to the filter box 5 of the baffle 16, and the limit spring 26 is inclined upward. The end of the limit spring 26 away from the baffle 16 is connected to the top of the collection box 8, and the limit spring 26 is always in a compressed state. The maximum angle between the baffle 16 and the top of the collection box 8 is a right angle, which can maintain support for the baffle 16 when the pushing pressure of the push plate 18 is less than that of the push plate 18, thereby preventing the collection box 8 from being connected with the filter box 5 at all times and preventing the collected impurities from escaping.

[0035] Working principle: When the reducer is working, the clean lubricating oil inside the reducer is sent into the filter cartridge 11 through the pipeline by the oil pump 4. At this time, the driving motor 9 is started to drive the guide stud 17 to rotate. The rotation of the guide stud 17 drives the meshing filter cartridge 11 to move synchronously, which not only makes the cleaning liquid shake to improve the cleaning effect, but also the rotation of the guide stud 17 synchronously drives the push plate 18 to move along the filter plate 10 to complete the pushing of the filtered impurities. In addition, the moving filter cartridge 11 makes the magnetic impurities adsorbed on the magnetic rod 14 in the forward direction of the guide sleeve 21 be hung by the inclined bottom of the guide sleeve 21, so that it falls into the area between the second shielding film 19 and the collecting cylinder 7, and as the filter cartridge 11 continues to move, it finally makes All of them fall into the collecting tube 7, which is convenient for subsequent cleaning. When the end of the filter tube 11 is connected to the side wall of the filter box 5, the continued rotation of the guide stud 17 can force the guide seat 23 connected to the filter tube 11 through the elastic rubber plate to compress the rubber plate to shrink, so that the rotation of the guide stud 17 continues to push the push plate 18 to move, completing the pushing and accumulation of impurities, so that the impurities filtered by the cleaning liquid enter the collection box 8, and the scraped magnetic waste enters the collection tube 7. After the push plate 18 is separated from the baffle 16, the baffle 16 is reset under the rebound of the limit spring 26 to prevent the impurities in the collection box 8 from escaping, thereby realizing the filtering and accumulation removal of impurities during the circulation operation of the cleaning liquid, avoiding the need for frequent replacement of the cleaning liquid.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
