Description

Technical Field

[0001] This invention relates to the field of washing and screening equipment technology, specifically to an integrated break-in and iron removal system for a worm gear reducer. Background Technology

[0002] In the transmission system of small agricultural machinery, the precision of the fit between the worm gear and the worm directly affects the smoothness of the machinery's operation and the ease of operation. To ensure that these key transmission components reach their optimal working condition, a specialized break-in process must be performed during production. During the break-in process, the meshing surfaces of the worm gear and the worm gradually reach an ideal fit through mutual friction. This not only significantly reduces transmission resistance but also effectively extends the service life of the components. However, this necessary break-in process inevitably generates metal friction debris. These fine iron filings mainly originate from the microscopic unevenness of the worm gear and worm contact surfaces. As the break-in continues, the roughness of the mating surfaces gradually decreases, and the coefficient of friction decreases accordingly. Ultimately, this allows the operator to achieve smooth drive of the worm gear and worm with only a small thrust when the machinery is operating in the field. It is worth noting that these iron filings generated during the break-in process need to be cleaned up promptly to avoid secondary damage to the transmission system.

[0003] The authorization announcement number CN222930993U discloses a rotary iron remover with cleaning function. According to its instruction manual and drawings, the scheme is as follows: a motor drives a fixed plate 1, a positioning rod and a magnetic cylinder to rotate and adsorb iron filings; a cylinder 1 drives a fixed plate 2, a fixed rod and a magnetic cylinder to move back and forth on a scraper to clean the iron filings on the surface of the magnetic cylinder; a cylinder 2 and a linkage mechanism drive a rotating shaft and a baffle to rotate, guiding waste and raw materials to different areas in the collection tank.

[0004] However, its design for removing iron filings still has some limitations: 1. The solution cannot directly handle the iron filings generated during the break-in process of the worm gear; 2. Since lubricating oil is required during the break-in process of the worm gear, how to handle the iron filings accumulated in the lubricating oil is one of the issues that needs to be considered; 3. If the iron filings separation module is not cleaned in time, the iron filings will inevitably return to the inside of the gearbox, causing damage during the break-in process; 4. How to efficiently coordinate the iron filings separation module and the cleaning of the module is also one of the issues that needs to be considered. Summary of the Invention

[0005] This invention addresses the problem of efficiently handling iron filings during the break-in process of worm gear reducers. It proposes an integrated break-in iron removal system for worm gear reducers. The design of the first and second chambers provides two iron filings collection areas. When one chamber is in the iron filings collection and adsorption state, the other chamber is in a self-cleaning state.

The sealing silicone shells are attached to the inner walls of the first cavity and the second cavity. The positions of the first electromagnet and the second electromagnet change simultaneously as the control slide rod slides.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The arrangement of the first and second chambers provides the entire iron filings collection mechanism with two collection areas. This design allows the other chamber to be in a self-cleaning state while either chamber is in the iron filings collection and adsorption state. The iron filings collection and adsorption state refers to the first or second electromagnet attracting iron filings from the inside of the first or second chamber, while the self-cleaning state involves automatically cleaning and discharging the iron filings from the first or second chamber to the outside. This cyclical switching between the first and second chamber operating modes enables continuous and efficient collection of iron filings from the lubricating oil, preventing iron filings from returning to the inside of the agricultural machinery gearbox and causing damage during the break-in process.

[0018] 2. The water discharged from the first or second outlet contains iron filings. If the iron filings discharged from the first or second outlet are collected, a quantitative correlation can be established between the amount of filings discharged from the outlet and the running-in status of the worm gear. In other words, the degree of mechanical wear can be visualized by monitoring the weight of the iron filings. This technical approach of transforming the physical cleaning process into measurable data is groundbreaking in the field of worm gear running-in of agricultural machinery gearboxes.

[0019] 3. The control slider can simultaneously change the positions of the first and second electromagnets. When the first or second cavity is in the iron filings collection and adsorption state, the piston rod can be automatically squeezed by the sealing silicone shell, thereby blocking the first or second water inlet and opening the second or third oil inlet. At the same time, the second or fourth sealing plug can block the first or second water outlet, and the first or third sealing plug can unblock the second and third oil outlets. The entire process is controlled by the control slider, coordinating the water circuit blocking while the oil inlet is opened, resulting in higher integration and efficiency.

[0020] 4. When the first or second chamber is in self-cleaning mode, the piston rod can automatically slide under the elastic force of the return spring, thereby opening the first or second water inlet. The sealing silicone shell blocks the second or third oil inlet. At the same time, the second or fourth sealing plug can move away from the first or second water outlet until it is in an open and conductive state, and the first or third sealing plug can block the second and third oil outlets. The entire process is controlled by the control slide rod. The self-cleaning water circuit opens while the oil circuit is blocked in a coordinated manner, resulting in higher integration and efficiency.

[0021] 5. The first and second electromagnets are magnetic only when they are energized. When the first cavity is in self-cleaning mode, the first electromagnet is not energized. When the second cavity is in self-cleaning mode, the second electromagnet is not energized. At this time, the cleaning nozzle can quickly complete the self-cleaning function of the first or second electromagnet. Attached Figure Description

[0037] The present invention will be further described below with reference to the embodiments illustrated in the accompanying drawings:

[0038] Example 1:

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, a worm gear reducer integral break-in and iron removal system includes a break-in worktable 1, an agricultural machinery gearbox 2 disposed on the surface of the break-in worktable 1, and a clamping element 3 for locking the agricultural machinery gearbox 2. The clamping element 3 is a rotary cylinder. The surface of the break-in worktable 1 is also provided with a power input component 4 for driving the worm to rotate and a load component 5 for controlling the torque of the worm gear.

[0040] In this embodiment, the power input assembly 4 includes a transmission support shell 41, a second drive motor 42, a power input shaft 43, and a transmission belt 44. The second drive motor 42 is provided at the bottom of the running-in table 1, and the transmission support shell 41 is provided on the surface of the running-in table 1. A bushing 45 is rotatably provided inside the transmission support shell 41, and the power input shaft 43 is slidably provided inside the bushing 45. The power input shaft 43 rotates with the rotation of the bushing 45. The bushing 45 is connected to the rotating shaft of the second drive motor 42 by the transmission belt 44, and the end of the power input shaft 43 can be engaged with the end of the worm gear of the agricultural machinery gearbox 2.

[0041] During the process of placing the agricultural machinery gearbox 2, which requires the break-in of the worm gear, the agricultural machinery gearbox 2 is first placed at the designated position on the surface of the break-in workbench 1, and the end of the piston rod 602 of the rotary cylinder can press against one end of the agricultural machinery gearbox 2.

[0042] At this time, the power input shaft 43 is pushed until it slides onto the end of the worm gear of the agricultural machinery gearbox 2. Then, the shaft of the second drive motor 42 drives the bushing 45 to rotate through the transmission belt 44. During the rotation, the bushing 45 can simultaneously drive the power input shaft 43 to rotate, which is relative to the simulated drive worm gear.

[0043] In this embodiment, the load assembly 5 includes a load support frame 51, a magnetic powder brake 52, a drive shaft 53, and a limiting chuck 54. The agricultural machinery gearbox 2 has hub support discs 23 on both sides that are connected to the worm gear inside the agricultural machinery gearbox 2. The surface of the running-in workbench 1 is slidably provided with the load support frame 51. The magnetic powder brake 52 is provided on one side of the load support frame 51. The drive shaft 53 is provided inside the magnetic powder brake 52. The end of the drive shaft 53 is provided with a limiting chuck 54 that can be locked onto the surface of the hub support disc 23.

[0044] The position of the sliding load support frame 51 relative to the surface of the running-in table 1 enables the locking between the limit chuck 54 and the hub support plate 23. When the worm gear inside the agricultural machinery gearbox 2 needs to be run-in, the limit chuck 54 needs to be locked onto the side of the hub support plate 23. At this time, the worm inside the agricultural machinery gearbox 2 can drive the worm wheel to rotate during rotation, and the hub support plate 23 also rotates simultaneously during the rotation of the worm wheel. At this time, the limit chuck 54 can transmit the power generated by the hub support plate 23 to the inside of the magnetic powder brake 52 through the drive shaft 53. When the magnetic powder brake 52 is under different current conditions, it can generate different degrees of load on the worm wheel.

[0045] The magnetic powder brake 5 consists of a stator (including an electromagnetic coil), a rotor, and filled magnetic powder. When the coil is energized, the magnetic field causes the magnetic powder to form a chain-like structure (magnetic powder chain), generating frictional resistance between the rotor and stator, thereby outputting braking torque. When the power is off, the magnetic powder returns to a loose state, and the resistance disappears. The braking torque of the magnetic powder brake 5 is directly proportional to the excitation current, and the load torque can be precisely controlled by adjusting the current. This load forces the worm gear meshing surface to generate greater friction, accelerating the wear and adhesion of the micro-protrusions on the contact surface, and improving meshing accuracy. Furthermore, by setting different load currents, the running stability and wear characteristics of the worm gear under different torques can be tested. By applying a controllable load to the worm gear, the magnetic powder brake 5 significantly improves the running-in effect of the worm gear. Its core lies in using electromagnetic controllability to simulate real working conditions and accelerate the optimization of the meshing surface.

[0046] Please continue to refer to this. Figure 2 The first oil inlet 21 and the first oil outlet 22 of the agricultural machinery gearbox 2 are both connected to the inside of the iron filings collection mechanism 6. The electromagnet inside the iron filings collection mechanism 6 can collect iron filings from the lubricating oil inside the agricultural machinery gearbox 2.

[0047] Please refer to Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, the iron filings collection mechanism 6 includes a collection housing 61, a second oil inlet 631, a second oil outlet 632, a third oil inlet 641, a third oil outlet 642, a control slide rod 65, a first electromagnet 66, and a second electromagnet 67. The interior of the collection housing 61 is divided by a cavity partition 62 to form a first cavity 63 and a second cavity 64. The side wall of the first cavity 63 is provided with a second oil inlet 631 and a second oil outlet 632, and the side wall of the second cavity 64 is provided with a third oil inlet 641 and a third oil outlet 642. The interior of the collection housing 61 is provided with a sliding control slide rod 65, and the surface of the control slide rod 65 is provided with a first electromagnet 66 and a second electromagnet 67 in the areas located in the first cavity 63 and the second cavity 64, respectively.

[0048] It should be noted that the sidewalls of the first electromagnet 66 and the second electromagnet 67 are provided with sealing silicone shells 68. The sealing silicone shells 68 are attached to the inner walls of the first cavity 63 and the second cavity 64. This arrangement prevents oil from flowing from the sidewalls of the first electromagnet 66 and the second electromagnet 67, and allows it to flow only through the interior of the first electromagnet 66 or the second electromagnet 67. When the first electromagnet 66 or the second electromagnet 67 is energized, these iron filings will be attracted to the interior of the first electromagnet 66 or the second electromagnet 67.

[0049] The positions of the first electromagnet 66 and the second electromagnet 67 change simultaneously as the control slider 65 slides. The positional changes of the first electromagnet 66 and the second electromagnet 67 can block the second oil inlet 631 or the third oil inlet 641.

[0050] The arrangement of the first cavity 63 and the second cavity 64 provides the entire iron filings collection mechanism 6 with two iron filings collection areas. This design allows the other cavity to be in a self-cleaning state while either cavity is in the iron filings collection adsorption state. The iron filings collection adsorption state refers to the first electromagnet 66 or the second electromagnet 67 adsorbing the iron filings inside the first cavity 63 or the second cavity 64. The self-cleaning state involves automatically cleaning and discharging the iron filings inside the first cavity 63 or the second cavity 64 to the outside. After either cavity is cleaned, it can switch back to the iron filings collection adsorption state. This cyclical switching of the working modes of the first cavity 63 and the second cavity 64 enables continuous and efficient collection of iron filings from the lubricating oil.

[0051] like Figure 4 As shown, the second oil inlet 631 and the third oil inlet 641 are connected, and the end of the second oil inlet 631 is connected to the end of the first oil outlet 22 of the agricultural machinery gearbox 2. Because the worm gear inside the agricultural machinery gearbox 2 generates iron filings during the break-in process, when oil flows out of the first oil outlet 22, this oil carrying iron filings will uniformly enter the interior of the first cavity 63 or the second cavity 64 through either the second oil inlet 631 or the third oil inlet 641. Whether the oil flows in through the second oil inlet 631 or the third oil inlet 641 is determined by the sliding of the control slide rod 65.

[0052] Since both the first cavity 63 and the second cavity 64 produce treated oil, the second oil outlet 632 and the third oil outlet 642 are connected to the oil inlet of the gear oil pump 8 through oil pipes, and the oil outlet of the gear oil pump 8 is connected to the first oil inlet 21 of the agricultural machinery gearbox 2. This treated oil will return to the interior of the agricultural machinery gearbox 2, avoiding the presence of iron filings during the break-in process of the worm gear and worm, which would reduce the break-in state between the meshing surfaces of the worm gear and worm.

[0053] like Figure 7 As shown, when the control lever 65 slides to the right, the right side of the first electromagnet 66 will adhere to the left side of the cavity partition 62. At this time, the top of the first electromagnet 66 blocks the top of the second oil inlet 631. Simultaneously, the second electromagnet 67 releases the blockage of the third oil inlet 641, allowing oil to flow in from the end of the third oil inlet 641 and out from the third oil outlet 642 through the middle of the second electromagnet 67. The first cavity 63 is in a self-cleaning state, and the second cavity 64 is in an iron filings collection and adsorption state.

[0054] like Figure 8 As shown, when the control lever 65 slides to the left, the left side of the second electromagnet 67 will adhere to the right side of the cavity partition 62. At this time, the top of the second electromagnet 67 blocks the top of the third oil inlet 641. Simultaneously, the first electromagnet 66 releases the blockage of the second oil inlet 631, allowing oil to flow in from the end of the second oil inlet 631 and out from the second oil outlet 632 through the middle of the first electromagnet 66. The first cavity 63 is in the iron filings collection and adsorption state, and the second cavity 64 is in the self-cleaning state.

[0055] Please continue to refer to this. Figure 7 and Figure 8 The side wall of the first cavity 63 is also provided with a first inlet 633 and a first outlet 634, and the side wall of the second cavity 64 is also provided with a second inlet 643 and a second outlet 644. The interior of the first inlet 633 and the second inlet 643 is provided with a sliding water channel limiting structure 60.

[0056] With this configuration, when the first electromagnet 66 slides below the first water inlet 633, it can push the water channel limiting structure 60 to slide inside the first water inlet 633. When the second electromagnet 67 slides below the second water inlet 643, it can push the water channel limiting structure 60 to slide inside the second water inlet 643. The position change of the water channel limiting structure 60 can control the first water inlet 633 or the second water inlet 643 to be in a conductive or blocked state.

[0057] To further control the opening or blocking state of the first inlet 633 or the second inlet 643, each waterway limiting structure 60 includes a return spring 601 and a piston rod 602. Each piston rod 602 is slidably disposed inside the first inlet 633 and the second inlet 643. The side walls of the first inlet 633 and the second inlet 643 are respectively provided with a first guide port 6331 and a second guide port 6431. Each piston rod 602 is hollow inside and is provided with a third guide port 603. The bottom of each piston rod 602 is provided with... With an inclined guide surface, the sealing silicone shell 68 on the side wall of the first electromagnet 66 and the second electromagnet 67 can push the piston rod 602 to slide during the sliding process. The top of the first water inlet 633 and the second water inlet 643 are provided with a support net 604. A return spring 601 is provided between the top of each piston rod 602 and the support net 604. When the piston rod 602 is pushed, the return spring 601 deforms and makes the third guide port 603 in a conductive state with the first guide port 6331 or the second guide port 6431.

[0058] like Figure 7 As shown, when the control slider 65 slides to the right, the right side of the first electromagnet 66 gradually comes into contact with the left side of the cavity partition 62. During this process, the sealing silicone shell 68 of the first electromagnet 66 gradually releases its pressure on the piston rod 602 above the first cavity 63. The piston rod 602 slides downward under the elastic force of the return spring 601. After the piston rod 602 slides to the designated position, the third guide port 603 inside the piston rod 602 above the first cavity 63 will be in a conductive state with the first guide port 6331, and the self-cleaning water flow can flow through the inside of the piston rod 602 to the inside of the first guide port 6331. At the same time, the sealing silicone shell 68 of the second electromagnet 67 gradually squeezes the bottom of the piston rod 602 above the second cavity 64. At this time, the return spring 601 is in a compressed state, and the third guide port 603 inside the piston rod 602 above the first cavity 63 will be blocked from the second guide port 6431. The self-cleaning water cannot flow through the inside of the piston rod 602 to the inside of the second guide port 6431.

[0059] like Figure 8As shown, when the control slider 65 slides to the right, the left side of the second electromagnet 67 gradually comes into contact with the right side of the cavity partition 62. During this process, the sealing silicone shell 68 of the second electromagnet 67 gradually releases its pressure on the piston rod 602 above the second cavity 64. The piston rod 602 slides downward under the elastic force of the return spring 601. After the piston rod 602 slides to the designated position, the third guide port 603 inside the piston rod 602 above the second cavity 64 will be in a conductive state with the second guide port 6431, and the self-cleaning water flow can flow through the inside of the piston rod 602 to the inside of the second guide port 6431. At the same time, the sealing silicone shell 68 of the first electromagnet 66 gradually squeezes the bottom of the piston rod 602 above the first cavity 63. At this time, the return spring 601 is in a compressed state, and the third guide port 603 inside the piston rod 602 above the first cavity 63 will be blocked from the first guide port 6331. The self-cleaning water flow cannot flow through the inside of the piston rod 602 to the inside of the first guide port 6331.

[0060] Whether the first guide port 6331 and the second guide port 6431 are in a conductive state determines whether the first cavity 63 and the second cavity 64 are in a self-cleaning state.

[0061] Please continue to refer to this. Figure 7 and Figure 8 As shown, the surface of the control slide 65 is provided with a valve stem assembly 69 in the area located in the first cavity 63 and the second cavity 64. When the first electromagnet 66 is in the position of blocking the second oil inlet 631, the valve stem assembly 69 can simultaneously control the second oil outlet 632 and the first water outlet 634 to be in the blocked state and the open state, respectively. When the second electromagnet 67 is in the position of blocking the third oil inlet 641, the valve stem assembly 69 can simultaneously control the third oil outlet 642 and the second water outlet 644 to be in the blocked state and the open state, respectively.

[0062] To further enable the valve stem assembly 69 to control the second oil outlet 632, the first water outlet 634, the third oil outlet 642, and the second water outlet 644: the valve stem assembly 69 includes a first support column 691, a second support column 692, a first sealing plug 694, a second sealing plug 690, a third support column 695, a fourth support column 696, a third sealing plug 698, and a fourth sealing plug 699. The first support column 691 and the second support column 692 are both disposed on the surface of the control slide rod 65 located in the first cavity 63. The first support column 691 extends towards the interior of the second oil outlet 632 with a first extension column 693. The end of the first extension column 693 is provided with a first sealing plug 694. The interior of the second oil outlet 632 is provided with an annular boss 6321. The end of the second support column 692 is provided with a second sealing plug 690 that can block the end of the first water outlet 634.

[0063] like Figure 7 As shown, whenever the first electromagnet 66 is adjusted until the sealing silicone shell 68 blocks the second oil inlet 631, the first sealing plug 694 blocks the second oil outlet 632 and the end of the second sealing plug 690 is away from the first water outlet 634. At this time, the first cavity 63 is in a self-cleaning state, and the second cavity 64 is in a state of collecting and adsorbing iron filings. The third guide port 603 will be in a conductive state with the first guide port 6331, and the oil flowing out of the first oil inlet 21 of the agricultural machinery gearbox 2 cannot enter the interior of the first cavity 63 from the second oil inlet 631.

[0064] The third support column 695 and the fourth support column 696 are both disposed on the surface of the control slide rod 65 located in the second cavity 64. The third support column 695 extends into the third oil outlet 642 with a second extension column 697. The end of the second extension column 697 is provided with a third sealing plug 698. The interior of the third oil outlet 642 is also provided with an annular boss 6321. The end of the fourth support column 696 is provided with a fourth sealing plug 699 that can block the end of the first water outlet 634.

[0065] Whenever the second electromagnet 67 adjusts its position until it blocks the third oil inlet 641, the third sealing plug 698 blocks the third oil outlet 642 and the fourth sealing plug 699 moves away from the end of the second water outlet 644. At this time, the first cavity 63 is in the iron filings collection and adsorption state, and the second cavity 64 is in the self-cleaning state. The third guide port 603 will be in the conductive state with the second guide port 6431, and the oil flowing out of the first oil inlet 21 of the agricultural machinery gearbox 2 cannot enter the interior of the second cavity 64 from the third oil inlet 641.

[0066] Please continue to refer to this. Figure 9 The interior of the cavity partition 62 is divided into a first water storage area 621 and a second water storage area 622 by a water passage partition 620. The water passage partition 620 is provided with a plurality of first cleaning pipes 651 and second cleaning pipes 652 on the side near the first cavity 63 and the second cavity 64, respectively. One side of the plurality of first cleaning pipes 651 is connected by an annular guide pipe 653. At least one end of the first cleaning pipe 651 is open and inserted into the interior of the second water storage area 622. The surfaces of the first cleaning pipes 651 and the second cleaning pipes 652 are respectively provided with cleaning nozzles 654 for cleaning iron filings on the surface of the first electromagnet 66 or the second electromagnet 67.

[0067] The first water storage area 621 has a first water storage interface 623 on its side wall, and the end of the first flow guide 6331 is connected to the inside of the first water storage interface 623 through a pipe.

[0068] The second water storage area 622 has a second water storage interface 624 on its side wall, and the end of the second guide port 6431 is connected to the inside of the second water storage interface 624 through a pipe.

[0069] The external water inlet pipe is connected to the top of the first water inlet 633 and the second water inlet 643. The water flow will pass through the support net 604 and enter the interior of the piston rod 602. At this time, the positional relationship between the third guide port 603 and the first guide port 6331 or the second guide port 6431 determines which water inlet is inlet.

[0070] like Figure 7 As shown, when the third guide port 603 inside the piston rod 602 located above the first cavity 63 is in a conductive state with the first guide port 6331, the water flows sequentially through the third guide port 603, the first guide port 6331, and the second water storage interface 624 into the interior of the second water storage area 622. Then, the water inside the second water storage area 622 flows in from the ends of several first cleaning pipes 651, and all the first cleaning pipes 651 are connected by the annular guide pipe 653. Finally, the cleaning nozzles 654 on the surface of the first cleaning pipes 651 wash away the iron filings on the first electromagnet 66 and gradually make it clean.

[0071] like Figure 8 As shown, when the third guide port 603 inside the piston rod 602 located above the first cavity 63 is in a conductive state with the second guide port 6431, the water flows sequentially through the third guide port 603, the second guide port 6431, and the first water storage interface 623 into the interior of the first water storage area 621. The annular guide pipe 653 is used to connect all the second cleaning pipes 652. Finally, the cleaning nozzles 654 on the surface of the second cleaning pipes 652 wash away the iron filings on the second electromagnet 67 and gradually make it clean.

[0072] Since the water from both the first outlet 634 and the second outlet 644 contains iron filings, in order to filter and collect these iron filings, the ends of the first outlet 634 and the second outlet 644 are connected to a filter 9 via pipes. The filter 9 collects and processes the impurities, and external workers can periodically remove and replace the filter 9 to re-filter the water from the first outlet 634 and the second outlet 644.

[0073] In this embodiment, please continue to refer to Figure 7The control slide 65 has a first bracket 655 and a second bracket 656 on its surface. The first bracket 655 and the second bracket 656 are respectively connected to the first electromagnet 66 and the second electromagnet 67. The control slide 65, the first bracket 655, and the second bracket 656 are hollow inside and have a first wire 657 and a second wire 658. The first wire 657 and the second wire 658 are respectively connected to the inside of the first electromagnet 66 and the second electromagnet 67.

[0074] With this configuration, the first electromagnet 66 and the second electromagnet 67 are controlled by the first wire 657 and the second wire 658, respectively. Both electromagnets 66 and 67 are magnetic only when energized. When the first cavity 63 is in a self-cleaning state, the first electromagnet 66 is de-energized. When the second cavity 64 is in a self-cleaning state, the second electromagnet 67 is de-energized.

[0075] One end of the control slide bar 65 is also provided with a toothed plate 659, and the surface of the running-in workbench 1 is also provided with a first drive motor 7. The end of the first drive motor 7 is also provided with a gear 71 that drives the toothed plate 659. The rotating shaft of the first drive motor 7 can drive the gear 71 to rotate during rotation. During the rotation, the gear 71 is driven by the toothed plate 659 to slide left and right when the control slide bar 65 is moved.

[0076] Example 2:

[0077] See Figures 11-12The difference between this embodiment and Embodiment 1 is that a novel iron filings collection and cleaning structure 10 is provided to replace the iron filings collection and cleaning mechanism 6 in Embodiment 1. This structure, by setting up an adsorption electromagnet 102 and an iron filings scraping cylinder 103, allows the adsorption electromagnet 102 to adsorb iron filings and impurities generated during the running-in process in the working fluid. The iron filings are then mechanically scraped off using the iron filings scraping cylinder 103, achieving initial separation between the working fluid and the iron filings. A strong magnetic feeder 108 further stabilizes and adsorbs the scraped iron filings, thus ensuring complete separation between the working fluid and the iron filings and achieving purification of the working fluid. Finally, a gear oil pump 8 is used to extract the purified working fluid for future use. The core advantages of this structure are as follows: Firstly, the working fluid is effectively blocked and diverted on the outer surface of the stainless steel shell 1022, avoiding direct impact on the internal third electromagnet 1021. As the scraping cylinder 103 rotates, the working fluid quickly spreads on the surface of the stainless steel shell 1022, forming a large-area dynamic contact, increasing the processing area by 3-5 times compared to static adsorption. Secondly, the third electromagnet 1021 is completely encapsulated and protected, not directly contacting the working fluid and scrap, effectively extending its service life. Furthermore, this structure also possesses a unique magnetization aggregation advantage: during the process of scrap being adsorbed by the stainless steel shell and pushed into the scrap settling zone 1062, it forms a clump structure after long-term magnetization by the third electromagnet 1021. This prevents it from easily redispersing even when it re-contacts the purified fluid in the scrap settling zone 1062. Combined with the secondary magnetic field set in the scrap settling zone 1062, this effectively prevents the scrap from rapidly dispersing, avoiding secondary pollution.

[0078] refer to Figure 11 , Figure 12 The iron filings collection and cleaning structure 10 includes:

[0079] The collection and cleaning housing 101 is assembled from the main housing 1011 and the first end cover 1012 and the second end cover 1013 located at both ends of the housing. It is hollow and forms a cylindrical collection and cleaning cavity 1014 to serve as a working space for collecting and cleaning iron filings.

[0080] The adsorption electromagnet 102 is columnar and coaxially installed in the collection and cleaning chamber 1014. It is connected to the collection and cleaning housing 101 via the support connecting rod 1023. It includes a third electromagnet 1021 inside and a stainless steel shell 1022 covering the third electromagnet 1021. The stainless steel shell 1022 is 0.5mm thick, has a smooth surface, and does not affect the generation of magnetic force. The magnetism of the third electromagnet 1021 can be controlled by switching the power on and off, thereby adsorbing iron filings and impurities generated in the working fluid due to the running-in process.

[0081] The iron filings scraping cylinder 103 is movably mounted on the outer periphery of the electromagnet 102. Multiple through holes 1031 are evenly distributed on its outer wall to allow iron filings to pass through and be attracted by the electromagnet 102. Multiple spiral scrapers 1032 are welded to its inner wall. The spiral scrapers 1032 have a very small gap (0.1-0.2 mm) with the outer wall of the electromagnet 102. In this embodiment, three spiral scrapers 1032 are provided, evenly distributed at 120° intervals, achieving a complete cycle of cleaning without dead angles.

[0082] The drive assembly 104 is used to drive the iron filings scraping cylinder 103 to rotate. It includes a motor (not shown in the figure) installed outside the first end cover 1012, a drive gear shaft 1041 connected to the motor, and a drive internal gear 1042 meshing with the drive gear shaft 1041. The drive internal gear 1042 is located on the inner wall of the end of the iron filings scraping cylinder 103.

[0083] The upper part of the collection and cleaning housing 101 is connected to multiple oil inlets 105, which are used to allow the working fluid containing iron filings and impurities to enter the collection and cleaning chamber 1014. In this embodiment, there are three oil inlets 105, all of which are located directly above the adsorption electromagnet 102. The working fluid enters in a tangential direction and forms a spiral downward flow.

[0084] Furthermore, this structure achieves the purification and extraction of the working fluid and the removal of iron filings through the following design.

[0085] The second end cap 1013 forms an upper clean oil zone 1061 and a lower iron filings sedimentation zone 1062 in the collection and cleaning chamber 1014 by setting a partition plate 106. The spiral scraper 1032 can push the iron filings scraped to the bottom of the collection and cleaning chamber 1014 and concentrate them in the iron filings sedimentation zone 1062 through its spiral pushing surface.

[0086] The clean oil zone 1061 is equipped with an oil extraction port 107, which is connected to the gear oil pump 8 via an oil pipe. The oil extraction port 107 is used to extract the purified working fluid and return it to the agricultural machinery gearbox 2 via a return oil pipe. A strong magnetic feeder 108 is detachably installed on the outside of the iron filings sedimentation zone 1062. It can efficiently capture and continuously adsorb iron filings. The strong magnetic feeder 108 can control its magnetism by controlling its power supply and adjust its magnetism by controlling the current.

[0087] The gear oil pump 8 is controlled to start and stop by a liquid level sensor. It automatically starts when the purified oil in the clean oil zone 1061 reaches the set liquid level and automatically stops when it is lower than the set liquid level.

[0088] The specific working process of this embodiment is as follows:

[0089] The working fluid containing iron filings enters sequentially through the oil inlet 105. When the working fluid passes through the through hole 1031 on the outer wall of the iron filings scraping cylinder 103, it is divided into multiple fine streams, increasing the contact time with the magnetic field. Then it flows over the surface of the adsorption electromagnet 102. Under the action of the strong magnetic field, the iron filings are quickly adsorbed onto the surface of the stainless steel shell 1022 (response time <0.1 seconds). With the help of the rotating iron filings scraping cylinder 103 (speed 5-15 rpm), the spiral scraper 1032 continuously scrapes off the iron filings from the surface. At the same time, the spiral pushing surface of the spiral scraper 1032 directionally pushes the iron filings and concentrates them in the iron filings sedimentation zone 1062. The iron filings are conveyed downward in a spiral trajectory at a conveying speed of about 2-5 mm / s. Crucially, the iron filings undergo an important physical state change during the long magnetization process (usually 3-5 seconds) on the surface of the adsorption electromagnet 102: the individual iron filings are fully magnetized, acquire a certain magnetism, and attract each other to form a denser agglomerate structure. These magnetized clumps have the following characteristics: ① The clump density is 30-50% higher than that of individual iron filings, significantly increasing the settling speed; ② The internal magnetic attraction of the clumps makes their structure stable, making them less prone to redispersing in liquid flow; ③ When the clumped iron filings and the purified working liquid re-converge in the iron filings settling zone 1062, their stable clump characteristics and the continuous magnetic field environment formed by the strong magnetic feeder 108 effectively prevent the iron filings from re-leaving the working liquid, avoiding the risk of secondary pollution. The strong magnetic feeder 108 also plays a role at the same time, forming a secondary magnetic field in the iron filings settling zone 1062, continuously and rapidly adsorbing the iron filings in the iron filings settling zone 1062, preventing them from leaching into the working liquid, and avoiding incomplete purification of the working liquid. The purified working liquid gradually exceeds the isolation plate 106 and accumulates in the clean oil zone 1061. The purified working liquid flows downward along the wall of the collection and cleaning chamber 1014 to avoid secondary pollution, and is drawn out from the oil extraction port 107 by the gear oil pump 8 for recycling. The entire process achieves a separation efficiency of over 95% in a single step. After secondary separation by the strong magnetic feeder 108, the overall separation efficiency reaches over 99.9%, and the iron filings content in the purified working fluid is <10mg / L. This design establishes a three-stage treatment mechanism of "magnetization-agglomeration-stabilization": the first stage achieves strong magnetic adsorption and full magnetization of iron filings through the adsorption electromagnet 102; the second stage promotes the formation of stable agglomerates of magnetized iron filings through the mechanical action of the spiral scraper 1032; the third stage creates a continuous magnetic field environment in the iron filings sedimentation zone 1062 through the strong magnetic feeder 108, ensuring the long-term stability of the agglomerated iron filings.

[0090] Due to the magnetized clumping characteristics of iron filings, the strong magnetic feeder 108 should be cleaned after 3-4 months of continuous operation. Specifically, the second end cap 1013 is unscrewed and removed, allowing the strong magnetic feeder 108 and the iron filings adsorbed in the iron filings sedimentation area 1062 to be removed as well. The strong magnetic feeder 108 is then disassembled and de-energized, and rinsed with clean water or other liquids to quickly remove the iron filings. At the same time, the electromagnet 102 can be de-energized to rinse it and the collection and cleaning chamber 1014, thus achieving regular cleaning of the device.

[0091] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
