[0001] The invention relates to the technical field of impurity cleaning, and in particular to a hydraulic distributor with a self-cleaning device. Background Art

[0002] Hydraulic distributor, also known as multi-way reversing valve, is a type of distributor. It is widely used in the hydraulic system control of construction machinery and agricultural machinery. It mainly controls the direction of hydraulic oil flow to the hydraulic cylinder by opening and closing the control valve to control the movement of the machinery. A working interface is set on the distributor to control the output or input of oil.

[0003] China Patent Publication No. CN111886415A discloses an invention patent named Hydraulic Distributor, which solves the problems of high manufacturing cost and warehouse inventory management complexity of hydraulic distributor and difficult leakage of working fluid between one module and another module of modular distributor. However, after the hydraulic distributor has been working for a period of time, the hydraulic oil tank is often mixed with impurities such as sediments. These sediments will circulate with the flow of oil, causing the machine to produce different noises and may even reduce the operating speed of the hydraulic distributor, thereby reducing the working effect of the hydraulic distributor, and may also reduce the anti-lubricating performance of the hydraulic oil and increase the wear of the machine. Summary of the invention

[0004] Technical solution: To solve the above problems, the present invention adopts the following technical solution: a turbulence generating device, comprising an installation box, a working chamber, a magnet block and a turbulence generating device. The working chamber is arranged inside the installation box, and the magnet block slides inside the installation box. The turbulence generating device cooperates with the magnet block inside the installation box to generate downward turbulence, which accelerates the passage of oil on the one hand, and makes impurities stick to the filter screen and will not disperse on the other hand, thereby increasing the filtering efficiency.

[0005] Preferably, the turbulence generating device includes a fixed frame, a gear set, a first bevel gear, a second bevel gear, fan blades and a meshing block.

DETAILED DESCRIPTION

[0038] Example 1

[0039] A hydraulic distributor with a self-cleaning device comprises a distributor body 1, working interfaces are evenly installed on the upper end of the distributor body 1, the working interfaces are used to control the output or input of oil, an installation box 2 is installed at the working interface on the upper end of the distributor body 1, the installation box 2 body is not made of metal and is not magnetic, a working chamber 3 is arranged in the installation box 2, and a self-cleaning device 4 is arranged in the working chamber 3, the self-cleaning device 4 can automatically clean and purify the hydraulic oil in the hydraulic distributor according to the temperature change of the hydraulic oil, save natural energy, ensure the anti-lubricating performance of the hydraulic oil and reduce the wear of the machine, ensure the working effect and normal working time of the hydraulic distributor; it can also prevent bubbles from moving with the hydraulic oil, so that the oil pressure in the whole working environment is maintained at a normal value, provide favorable conditions for the operation of the hydraulic distributor, and reduce the probability of failure of the hydraulic distributor; the distributor body 1 is a three-way multi-way reversing valve.

[0040] The self-cleaning device 4 includes a filter plate 41, a limit groove 42, a slide frame 43, an impurity cleaning mechanism 44, a temperature-sensitive magnetic variable block 45, a magnet block 46 and a spring rope 47. The filter plates 41 are relatively installed on the inner walls of the left and right sides of the working chamber 3, and the limit grooves 42 are relatively opened on the inner walls of the front and rear sides of the working chamber 3. The slide frame 43 is slidably installed in the limit groove 42, and the impurity cleaning mechanism 44 is connected between the slide frames 43. The temperature-sensitive magnetic variable blocks 45 are symmetrically arranged on the left and right sides of the working chamber 3. The temperature-sensitive magnetic variable blocks 45 can change their own magnetic force through temperature changes. The opposite side of the impurity cleaning mechanism 44 is installed with a magnet block 46. The impurity cleaning mechanism 44 is connected to the working chamber 3 through a spring rope 47. A magnetic suction plate 440 is also installed in the lower side of the installation frame 441, which is used to absorb metal impurities in the impurities; the cooperation between the temperature-sensitive magnetic variable block 45 and the magnet block 46 is to utilize the temperature of the hydraulic oil for driving, and its working purpose can be equivalent to that of an electric push rod.

[0041] Specifically, when the hydraulic distributor is not working, the hydraulic oil is in a cooling state. At this time, the magnetic force of the temperature-sensitive magnetic variable block 45 is at a normal value, and under the magnetic attraction between the temperature-sensitive magnetic variable block 45 and the magnet block 46, the temperature-sensitive magnetic variable block 45 is located close to the magnet block 46. At this time, the spring rope 47 is stretched to the limit position under the magnetic attraction between the temperature-sensitive magnetic variable block 45 and the magnet block 46; when the hydraulic distributor starts to work, the hydraulic oil in the hydraulic distributor starts to move. Due to the friction inside the hydraulic distributor and the movement of the hydraulic oil itself, the temperature of the hydraulic oil in the hydraulic distributor gradually increases. At this time, the magnetic force of the temperature-sensitive magnetic variable block 45 gradually weakens. Under the elastic action of the spring rope 47, the magnet block 46 gradually moves away from the temperature-sensitive magnetic variable block 45 and drives the impurity cleaning mechanism 44 to move away from the temperature-sensitive magnetic variable block 45. At this time, the impurity cleaning mechanism The structure 44 drives the slide frame 43 to slide in the limit groove 42. When the hydraulic distributor is in a normal working state, the temperature of the hydraulic oil is within a constant temperature range, so that the impurity cleaning mechanism 44 is maintained at a position away from the temperature-sensitive magnetic variable block 45. At this time, the filter plate 41 filters the moving hydraulic oil and adsorbs impurities on the filter plate 41; when the hydraulic distributor stops working, the hydraulic oil gradually cools down. At this time, the magnetic force of the temperature-sensitive magnetic variable block 45 gradually recovers. The magnet block 46 gradually moves toward the direction close to the temperature-sensitive magnetic variable block 45 under the magnetic force of the temperature-sensitive magnetic variable block 45, so that the impurity cleaning mechanism 44 gradually moves toward the direction close to the temperature-sensitive magnetic variable block 45 and cleans the impurities remaining on the filter plate 41 when the hydraulic distributor is working, maintains the filtering effect of the filter plate 41, and can also collect impurities through the impurity cleaning mechanism 44 to prevent impurities from continuing to mix into the hydraulic oil.

[0042] The upper end of the installation box 2 is provided with an opening, and a sealing plate 21 is installed at the opening by bolts, so that the sealing plate 21 and the installation box 2 can be disassembled. After the self-cleaning device 4 has worked for a period of time, the sealing plate 21 can be removed to clean the self-cleaning device 4. Connecting parts 22 are relatively opened on both sides of the upper end of the sealing plate 21, and the connecting parts 22 correspond to the working interface. An annular seal 23 is also provided at the contact position between the sealing plate 21 and the opening. The annular seal 23 is a circular shape, and the annular seal 23 is further used to prevent oil leakage from the installation box 2.

[0043] A flow direction control unit 31 is provided in the middle of the working chamber 3. The four sides of the flow direction control unit 31 are all arc surfaces. The opposite side of the filter plate 41 is tightly attached to the surface of the flow direction control unit 31. The hydraulic oil in motion is diverted through the flow direction control unit 31 so that the hydraulic oil can be smoothly filtered by the filter plates 41 on both sides.

[0044] The impurity cleaning mechanism 44 includes a mounting frame 441, a fixed platform 442, a cleaning rod 443, a compression spring 444, an incomplete gear 445, a resistance-increasing layer 446, a shift plate 447, a rotating gear 448 and a transmission gear 449. The mounting frames 441 are symmetrically fixed on the upper and lower sides between the slide frames 43. The side of the lower mounting frame 441 away from the magnet block 46 is connected to the fixed platform 442. The cleaning rod 443 is slidably installed in the fixed platform 442. The cleaning rod 443 is connected to the fixed platform 442 through a compression spring 444. The cleaning rod 443 is always closely attached to the lower end of the filter plate 41 through the compression spring 444, and the upper end of the cleaning rod 443 is closely attached to the filter plate 41. The lower end surface of the plate 41, the side of the lower mounting frame 441 close to the magnet block 46 is rotatably mounted with an incomplete gear 445, the upper side of the incomplete gear 445 close to the magnet block 46 is provided with a resistance increasing layer 446, and smooth portions are provided on both sides of the resistance increasing layer 446. The friction force generated between the side of the upper side of the incomplete gear 445 away from the magnet block 46 and the filter plate 41 cannot drive the incomplete gear 445 to rotate, and the gear teeth on the incomplete gear 445 are located at the end of the lower side of the surface of the incomplete gear 445 away from the magnet block 46. A shift plate 447 is installed in the lower mounting frame 441 through a rotating shaft, and the shift plate 447 is made of elastic material, and a rotating shaft is fixed in the middle of the rotating shaft. The rotating gear 448 is connected to the mounting frame 441 through a torsion spring. The torsion spring is used to maintain the initial state of the shift plate 447 in a horizontal state. A transmission gear 449 is meshed between the rotating gear 448 and the incomplete gear 445. The transmission gear 449 is rotatably mounted in the mounting frame 441 on the lower side. Specifically, when the hydraulic distributor starts to work, the magnet block 46 gradually moves away from the temperature-sensitive magnetic variable block 45 and drives the impurity cleaning mechanism 44 to move away from the temperature-sensitive magnetic variable block 45. The mounting frame 441 and the fixed platform 442 move away from the temperature-sensitive magnetic variable block 45 at the same time. Since the hydraulic distributor has just started to work for a period of time at this time, the filter plate 41 is not There are not many impurities. Even if the cleaning rod 443 cleans the lower end surface of the filter plate 41, it cannot clean out the impurities. At this time, the incomplete gear 445 is closely attached to the lower end surface of the filter plate 41 for relative movement. Since the incomplete gear 445 follows the installation frame 441 to move away from the temperature-sensitive magnetic variable block 45, the incomplete gear 445 has a tendency to rotate clockwise. However, both sides of the resistance-increasing layer 446 are provided with smooth parts, which cannot drive the incomplete gear 445 to rotate through friction. Therefore, the shift plate 447 is still in a horizontal state and in contact with the fixed platform 442 when the hydraulic distributor starts to work, so as to seal the impurities collected in the installation frame 441.When the hydraulic distributor is finished and stops working, the magnet block 46 gradually moves toward the direction close to the temperature-sensitive magnetic variable block 45 and drives the impurity cleaning mechanism 44 to move toward the direction close to the temperature-sensitive magnetic variable block 45. The installation frame 441 and the fixed platform 442 move toward the direction close to the temperature-sensitive magnetic variable block 45 at the same time. At this time, impurities are already distributed on the filter plate 41. The impurities are scraped off by the cleaning rod 443. At this time, the incomplete gear 445 gradually contacts the resistance-increasing layer 446 and drives the incomplete gear 445 to rotate, so that the transmission gear 449 rotates accordingly and drives the rotating gear 448 to rotate, so that the shift plate 447 rotates downward. At this time, the scraped impurities enter the installation frame 441 under the action of their own gravity for collection. ;

[0045] The impurity cleaning mechanism 44 also includes a pressure roller 451 and a truncated cone protrusion 452. The pressure roller 451 is rotatably installed in the upper installation frame 441. A plurality of truncated cone protrusions 452 are evenly installed on the surface of the pressure roller 451 along its circumference. The truncated cone protrusions 452 are matched with the filter holes. During the movement of the installation frame 441, the pressure roller 451 moves on the filter plate 41, and the truncated cone protrusions 452 are inserted into the filter holes. A certain pressure is applied to the filter plate 41 by the pressure roller 451 so that the impurity cleaning process can proceed smoothly. Impurities stuck in the filter holes can also be pounded out by the truncated cone protrusions 452 to ensure the effect of impurity cleaning.

[0046] The impurity cleaning mechanism 44 also includes an L-shaped extrusion block 4401, a filtrate plate 4402, an extrusion spring 4403, an extrusion groove 4404, a clamping groove 4405, a clamping block 4406, a clamping spring 4407, an arc-shaped top block 4408 and a stacking cavity 4409. An L-shaped extrusion block 4401 is fixed to one end of the upper side of the fixed platform 442 close to the temperature-sensitive magnetic variable block 45, and a receiving groove is provided on the side of the shift plate 447 away from the temperature-sensitive magnetic variable block 45. A filtrate plate 4402 is slidably installed in the receiving groove. The filtrate plate 4402 can only pass liquid but not impurities. The end of the filtrate plate 4402 away from the temperature-sensitive magnetic variable block 45 is tightly attached to the fixed platform 442, and the filtrate plate 4402 is connected to the receiving groove through the extrusion spring 4403. An extrusion groove 4404 is provided in the middle of the upper end surface of the filtrate plate 4402. The extrusion groove 4404 is trapezoidal and the side away from the temperature-sensitive magnetic variable block 45 is an inclined surface. A clamping groove 4405 is provided on the lower end surface of the filtrate plate 4402. A clamping block 4406 is slidably installed at the lower end of the accommodating groove. The clamping block 4406 is connected to the accommodating groove through a clamping spring 4407. The clamping block 4406 and the clamping groove 4405 are correspondingly arranged. An arc-shaped top block 4408 is installed on the side of the lower end surface of the installation frame 441 close to the temperature-sensitive magnetic variable block 45. A stacking cavity 4409 is provided at the lower end of the installation frame 441. The opening of the stacking cavity 4409 is located above the arc-shaped top block 4408. In specific operation, when the hydraulic distributor is opened to work, the shift plate 447 is rotated downward. During the rotation, under the elastic action of the squeezing spring 4403, the filtrate plate 4402 always moves downward against the side wall of the fixed platform 442, so the filtrate plate 4402 squeezes the impurities previously fallen into the installation frame 441 in the direction close to the stacking chamber 4409. At this time, the hydraulic oil in the installation frame 441 overflows and exchanges hydraulic oil with the outside. When the lower end of the filtrate plate 4402 gradually contacts the arc-shaped top block 4408 and moves to the vertical direction, the arc-shaped top block 4408 pushes the filtrate plate 4402 to move upward and shrink in the receiving groove, and the position of the filtrate plate 4402 is limited by the cooperation between the card slot 4405, the card block 4406 and the card spring 4407. At this time, new impurities fall into the installation frame 441. When the hydraulic distribution After the device is finished working and the temperature of the hydraulic oil gradually decreases, the shift plate 447 gradually rotates upward. At this time, the filtrate plate 4402 can no longer move closely on the side wall of the fixed platform 442, so that the shift plate 447 moves to the top of the impurities at the bottom of the mounting frame 441, completing the isolation of the impurities from the hydraulic environment. When the shift plate 447 gradually returns to the horizontal position, the L-shaped extrusion block 4401 gradually contacts the extrusion groove 4404, thereby pushing the filtrate plate 4402 to move out of the receiving groove, so that the block 4406 is disengaged from the groove 4405, and then the filtrate plate 4402 is again closely attached to the side wall of the fixed platform 442. No additional drive is required to complete the accommodation and isolation of impurities, prevent the impurities from being mixed with the hydraulic oil again, and ensure the quality of impurity cleaning.

[0047] Example 2

[0048] On the basis of removing impurities in Example 1, it is also possible to explore the removal of bubbles that may exist in the hydraulic distributor. Bubble cleaning mechanisms 48 are relatively arranged on the left and right sides of the upper inner side of the working chamber 3; the bubble cleaning mechanism 48 includes a bubble separation plate 481, a bubble collection box 482, an air inlet 483, a memory metal strip 484 and a flexible anti-seepage layer 485. The bubble separation plates 481 are symmetrically installed on the left and right sides of the upper inner side of the installation box 2. A plurality of bubble filter holes are provided on the bubble separation plates 481 and the bubble separation plates 481 are arranged in an inclined manner. The inclined bubble separation plates 481 are arranged to increase the contact area between the hydraulic oil and the bubble separation plates 481 and to better In order to separate bubbles, a bubble collecting box 482 group is relatively installed on the left and right sides of the upper inner wall of the installation box 2 in a detachable manner. The bubble collecting box 482 group includes two bubble collecting boxes 482. A plurality of air inlets 483 are provided at the lower end of the bubble collecting box 482. The air inlet 483 is truncated cone-shaped and its diameter gradually decreases from bottom to top. The function of the air inlet 483 is to allow bubbles to smoothly enter the bubble separation plate 481 and prevent bubbles from flowing out. A plurality of memory metal strips 484 are relatively installed on the left and right sides of the lower end of the bubble collecting box 482. The initial The initial state is that it is closely attached to the lower end surface of the bubble collection box 482, and a flexible anti-seepage layer 485 is connected between the memory metal strips 484; when the hydraulic distributor starts to work, the hydraulic oil in the hydraulic distributor starts to move. Due to the friction inside the hydraulic distributor and the movement of the hydraulic oil itself, the temperature of the hydraulic oil in the hydraulic distributor gradually increases, so that the memory metal strips 484 drive the flexible anti-seepage layer 485 to open. At the same time, the bubbles are separated from the hydraulic oil by the bubble separation plate 481, so that the bubbles enter between the bubble separation plate 481 and the installation box 2. Due to the bubbles themselves Properties, the bubbles move upward and move to the air inlet 483 on the lower end surface of the bubble collecting box 482, some bubbles contact the air inlet 483 and enter the bubble collecting box 482, and some bubbles remain on the lower end surface of the bubble collecting box 482. When the hydraulic distributor stops working, the memory metal strip 484 drives the flexible anti-seepage layer 485 to restore its initial state, so that the flexible anti-seepage layer 485 squeezes the bubbles and allows the bubbles to enter the bubble collecting box 482 through the air inlet 483, preventing the bubbles from moving with the hydraulic oil, so that the oil pressure in the entire working environment is maintained at a normal value.

[0052] Specifically, the turbulence generating device 5 also includes a fixed plate 56, a spring telescopic rod 58, a fixed rod 59 and a rotating rod 510. The fixed plate 56 is arranged on one side of the upper end of the magnet block 46 close to the middle position of the working chamber 3, and the engaging block 57 is close to the fixed plate 56. The spring telescopic rod 58 is fixedly connected between the side of the engaging block 57 away from the fixed plate 56 and the magnet block 46. The fixed rod 59 is fixedly connected to the inner wall of the working chamber 3, and the end of the fixed rod 59 is rotatably connected to the second bevel gear 54. The rotating rod 510 is rotatably connected to the inner wall of the working chamber 3, and the end of the rotating rod 510 is fixedly connected to the first bevel gear 53.

[0053] Specifically, when the magnet block 46 moves from the middle position inside the working chamber 3 to both sides, the fan blades 55 rotate to generate downward turbulence. When the magnet block moves from the middle position inside the working chamber to both sides, due to the action of the fixed plate, the meshing block does not rotate and meshes normally with the gear set. When the magnet block moves in the opposite direction, it rotates, and the gear set cannot be driven to rotate in the opposite direction, causing the fan blades to rotate in the opposite direction, thereby avoiding upward turbulence.
