Description

Technical Field

[0001] The present invention relates to the technical field of tractor distributors, in particular to a distributor for tractors with a reset mechanism. Background Art

[0002] With the rapid development of the domestic tractor industry, the purchase of tractor parts has gradually increased. The tractor hydraulic lifter is an important component of the tractor, and the main core control component of the lifter is the distributor, which is generally installed in the inner cavity of the lifter or externally on the right side of the lifter. Its superior performance determines the working reliability of the hydraulic system.

[0003] Since the working environment of tractors is relatively harsh and they work in high temperature, dust, load, corrosion, vibration and other environments for a long time, dust and impurities can easily enter the hydraulic system. If dust and impurities enter the hydraulic oil, the flow of hydraulic oil in the distributor will cause blockage or even damage to the hydraulic components. Some tractor distributors will be equipped with a filter to filter the hydraulic oil to prevent dust and impurities from entering the hydraulic system. However, the filter will be blocked after long-term use, and it is necessary to regularly shut down the machine, disassemble it for cleaning and replacement, and the later maintenance cost is high. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a tractor dispenser with a reset mechanism.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A tractor distributor with a reset mechanism includes a distributor body, a side wall of the distributor body is provided with an oil inlet channel, and further includes:

[0007] The filtration unit is a kind of filter mechanism, and it comprises two kinds of filter mechanisms, and two kinds of filter mechanisms are combined with each other to form a filter mechanism, and a filter mechanism is combined with two kinds of filter mechanisms.

[0008] Preferably, a reset mechanism is installed in the mounting block, and the reset mechanism includes a reset cavity opened in the mounting block, the inner wall of the reset cavity is sealed and slidably connected with a sliding plug, one end of the two racks extends into the reset cavity and is fixedly connected to the sliding plug, and the side wall of the mounting block is provided with multiple pressure relief channels, and the multiple pressure relief channels are connected to the reset cavity through a one-way tube, and the inner wall of the reset cavity is provided with a one-way hole.

[0009] Preferably, the reset mechanism further comprises a first solenoid valve installed on the inner wall of the pressure relief channel, and a second solenoid valve is installed on the inner wall of the one-way hole.

[0010] Preferably, a trigger mechanism is installed in the circular groove, and the trigger mechanism includes a hole groove opened on the inner wall of the circular groove, one end of the hole groove is connected to the installation cavity, an insulating column is slidably connected to the inner wall of the hole groove, a conductive column is slidably connected to the inner wall of the hole groove, one end of the conductive column is fixedly connected to the insulating column, and a conductive sleeve is embedded in the inner wall of the hole groove.

[0011] Preferably, the first solenoid valve, the second solenoid valve, the conductive column, the conductive sleeve and the external power supply are electrically connected via a wire.

[0012] Preferably, a cleaning mechanism is installed on the mounting block, and the cleaning mechanism includes two cleaning boxes symmetrically fixedly connected to the side walls of the filter box, the inner wall of the cleaning box is sealed and slidably connected with a slide, and a connecting rod is fixedly connected between the slide and the filter plate. The slide divides the interior of the cleaning box into two parts: a cleaning chamber and a liquid supply chamber, and the inner wall of the cleaning chamber is fixedly connected with a plurality of soft bristles.

[0013] Preferably, the cleaning mechanism also includes a liquid inlet cavity provided in the side wall of the cleaning box, a plurality of liquid spray holes are provided on the inner wall of the liquid inlet cavity, the liquid supply cavity is connected to the liquid inlet cavity through a one-way liquid supply pipe, the inner wall of the liquid supply cavity is fixedly connected with a one-way liquid inlet pipe, a second spring is fixedly connected between the slide plate and the inner wall of the liquid supply cavity, and a plurality of debris discharge holes are provided on the side wall of the cleaning box.

[0014] Preferably, an oil inlet pipe is fixedly connected to the side wall of the filter box.

[0016] The present invention has the following beneficial effects:

[0017] 1. By setting up a filtering mechanism, the dust and impurities in the hydraulic oil can be blocked by the filter plate, thereby ensuring that the hydraulic oil entering the distributor body does not contain dust and impurities, thereby greatly reducing the risk of blockage inside the distributor body;

[0018] 2. As the distributor body is used, more and more impurities accumulate on the filter plate surface and in the filter holes, causing the pressure on the right side of the mounting block to gradually increase, thereby pushing the circular plate to move, driving the lead screw to rotate, and then causing the two filter plates to move synchronously. One moves into the cleaning chamber for cleaning, and the other moves into the filter box for filtering. This allows the filter to continue to be filtered without stopping the machine for maintenance.

[0019] 3. During the synchronous movement of the two filter plates, since the moving distances are equal, the flow rate of hydraulic oil from the filter box into the oil inlet channel will not change much, and dynamic balance can be maintained, thereby ensuring the normal operation of the distributor body;

[0020] 4. By setting up a reset mechanism and a trigger mechanism, the two filter plates can automatically perform repeated filtering and cleaning operations alternately, ensuring effective filtration of dust and impurities while cleaning the filter plates synchronously. This ensures normal filtering performance of the filter plates without the need for regular maintenance, making it more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Reference Figure 1 - Figure 9 A tractor distributor with a reset mechanism includes a distributor body 1, an oil inlet channel 2 is opened on the side wall of the distributor body 1, and further includes:

[0033] The filtering mechanism includes a filter box 3 fixedly connected to the side wall of the oil inlet channel 2, the inner wall of the filter box 3 is sealed and fixedly connected to the mounting block 4, the side wall of the mounting block 4 is symmetrically provided with two slide grooves 5, the inner walls of the two slide grooves 5 are sealed and slidably connected to the filter plate 6, the inner wall of the slide groove 5 is rotatably connected to the lead screw 7, the side wall of the lead screw 7 is threadedly connected to the filter plate 6, the inner wall of the mounting block 4 is provided with a mounting cavity 8, one end of the two lead screws 7 extends to the inner wall of the mounting cavity 8 and is fixedly connected to a gear 9, and the side wall of the mounting block 4 is provided with a circular groove 10. The inner wall of the circular groove 10 is slidably connected with a slide rod 11. One end of the slide rod 11 extends to the inner wall of the mounting cavity 8 and is fixedly connected to a mounting plate 12. The side wall of the mounting plate 12 is symmetrically fixedly connected with two racks 13. The two racks 13 are respectively engaged with the two gears 9. The inner wall of the circular groove 10 is sealed and slidably connected with a circular plate 14. One end of the slide rod 11 is fixedly connected to the circular plate 14. The side wall of the slide rod 11 is sleeved with a first spring 15. The two ends of the first spring 15 are respectively fixedly connected to the inner wall of the circular groove 10 and the side wall of the circular plate 14.

[0034] It should be noted that only half of the filter plate 6 is provided with filter holes, and the other half is the plate surface.

[0035] Furthermore, dust and impurities in the hydraulic oil will be blocked by the filter plate 6, thereby ensuring that the hydraulic oil entering the distributor body 1 does not contain dust and impurities, thereby greatly reducing the risk of clogging inside the distributor body 1. However, as the distributor body 1 is used, more and more impurities will accumulate on the surface of the filter plate 6 and in the filter holes, thereby causing the filter holes of the filter plate 6 to be clogged. At this time, the hydraulic oil circulation effect of the filter plate 6 will become worse, thereby causing the pressure on the right side of the mounting block 4 to gradually increase (such as Figure 4 As shown), when the pressure increases, it will act on the circular plate 14, overcoming the elastic force of the first spring 15, thereby pushing the circular plate 14 to slide inside the circular groove 10, and then pushing the slide bar 11 to slide, driving the mounting plate 12 to move, thereby driving the rack 13 to move, driving the two gears 9 to rotate in the same direction, and then driving the two lead screws 7 to rotate, so that the two filter plates 6 will be driven to move upward synchronously, and the filter plate 6 located on the upper side will slowly move out of the filter box 3 for cleaning, while the filter plate 6 located on the lower side will slowly move into the filter box 3 for filtering (as shown). Figure 4 As shown in the figure, during this process, the two filter plates 6 will move synchronously, the filtering surface of one filter plate 6 will slowly move out of the filter box 3, and the filtering surface of the other filter plate 6 will slowly enter the filter box 3. Therefore, at this time, the flow rate of hydraulic oil from the filter box 3 into the oil inlet channel 2 will basically not change much, and dynamic balance can be maintained, thereby ensuring the normal operation of the distributor body 1.

[0036] A reset mechanism is installed in the mounting block 4, and the reset mechanism includes a reset chamber 16 opened in the mounting block 4. The inner wall of the reset chamber 16 is sealed and slidably connected with a sliding plug 17. One end of the two racks 13 extends into the reset chamber 16 and is fixedly connected to the sliding plug 17. A plurality of pressure relief channels 18 are opened on the side wall of the mounting block 4. The plurality of pressure relief channels 18 are connected to the reset chamber 16 through a one-way tube 19. The one-way tube 19 only allows the hydraulic oil in the pressure relief channel 18 to enter the reset chamber 16. A one-way hole 20 is opened on the inner wall of the reset chamber 16. The one-way hole 20 only allows the hydraulic oil in the reset chamber 16 to discharge from the reset chamber 16.

[0037] The reset mechanism further includes a first solenoid valve 21 installed on the inner wall of the pressure relief channel 18 , and a second solenoid valve 22 installed on the inner wall of the one-way hole 20 .

[0038] A trigger mechanism is installed in the circular groove 10. The trigger mechanism includes a hole groove 23 provided on the inner wall of the circular groove 10. One end of the hole groove 23 is connected to the installation cavity 8 (as shown in FIG. Figure 5 As shown), the inner wall of the hole groove 23 is slidably connected to the insulating column 24, the inner wall of the hole groove 23 is slidably connected to the conductive column 25, one end of the conductive column 25 is fixedly connected to the insulating column 24, and the inner wall of the hole groove 23 is embedded with a conductive sleeve 26.

[0039] The first solenoid valve 21 , the second solenoid valve 22 , the conductive column 25 , the conductive sleeve 26 and the external power supply are electrically connected via wires.

[0040] A cleaning mechanism is installed on the mounting block 4, and the cleaning mechanism includes two cleaning boxes 27 symmetrically fixedly connected to the side walls of the filter box 3. The inner wall of the cleaning box 27 is sealed and slidably connected with a slide plate 28, and a connecting rod 38 is fixedly connected between the slide plate 28 and the filter plate 6. The slide plate 28 divides the interior of the cleaning box 27 into two parts: a cleaning chamber 281 and a liquid supply chamber 282. A plurality of soft bristles 29 are fixedly connected to the inner wall of the cleaning chamber 281.

[0041] Furthermore, when the upper filter plate 6 is completely moved into the cleaning box 27, the lower filter plate 6 will completely enter the filter box 3, and the circular plate 14 will move to fit the inner wall of the circular groove 10 and will be unable to move further. The circular plate 14 will push the conductive column 25 to contact the conductive sleeve 26. At this time, the circuit is connected, the first solenoid valve 21 is energized to open, and the second solenoid valve 22 is energized to close. As the dispenser body 1 is used, the filter plate 6 located below will gradually be blocked due to the accumulation of dust and impurities, causing the pressure on the right side of the mounting block 4 to continue to increase. When the pressure exceeds the pressure threshold of the one-way valve inside the one-way tube 19, the one-way valve will open, and the hydraulic oil will enter the one-way tube 19 through the pressure relief hole 18, and then enter the reset chamber 16 through the one-way tube 19, and then the hydraulic oil will push the slide plug 17 to move, driving the rack 13 to move and reset, and then driving the gear 9 to rotate in the opposite direction, driving the two When the filter plate 6 is completely cleaned, the mounting plate 12 will push the conductive post 25 back to its original position by pushing the insulating post 24, so that the conductive post 25 is separated from the conductive sleeve 26, and the circuit is disconnected. The first solenoid valve 21 is powered off and closed, and the second solenoid valve 22 is powered off and opened, and then the filter plate 6 can be pushed upward again, and so on. During the use of the dispenser body 1, the two filter plates 6 can be filtered and cleaned alternately, which can ensure that dust and impurities are effectively filtered and the filter plates 6 can be cleaned synchronously. There is no need to maintain the filter plates 6 regularly, and the filtering performance of the filter plates 6 can be guaranteed to be normal, which is more convenient to use.

[0042] The cleaning mechanism also includes a liquid inlet cavity 30 provided in the side wall of the cleaning box 27, a plurality of liquid spray holes 31 are provided on the inner wall of the liquid inlet cavity 30, the liquid supply cavity 282 is connected to the liquid inlet cavity 30 through a one-way liquid supply pipe 32, the one-way liquid supply pipe 32 only allows the cleaning liquid in the liquid supply cavity 282 to enter the liquid inlet cavity 30, the inner wall of the liquid supply cavity 282 is fixedly connected to a one-way liquid inlet pipe 33, the other end of the one-way liquid inlet pipe 33 is connected to an external container for storing cleaning liquid, and the one-way liquid inlet pipe 33 only allows external cleaning liquid to enter the liquid supply cavity 282, a second spring 34 is fixedly connected between the slide 28 and the inner wall of the liquid supply cavity 282, and a plurality of impurity discharge holes 39 (such as Figure 9 shown).

[0043] Furthermore, when the filter plate 6 slowly enters the cleaning box 27, the sliding plate 28 will be driven to move by the connecting rod 38, and then the cleaning liquid in the liquid supply chamber 282 will be squeezed into the liquid inlet chamber 30 through the one-way liquid supply pipe 32, and then the cleaning liquid will be sprayed out through multiple spray holes 31 to flush the filter plate 6, and the filter plate 6 will generate friction with the soft bristles 29 during the movement, which can improve the cleaning effect, thereby quickly cleaning the impurities on the surface of the filter plate 6 and the filter holes, and then the dust and impurities will be discharged through the drainage holes 39 along with the cleaning liquid.

[0044] An oil inlet pipe 35 is fixedly connected to the side wall of the filter box 3 .

[0045] A plurality of oil distribution channels 36 are opened on the side wall of the distributor body 1 , and a reset valve stem 37 is installed on the side wall of the distributor body 1 .

[0046] In the present invention, the hydraulic oil enters the filter box 3 through the oil inlet pipe 35, and then the hydraulic oil is filtered through the filter plate 6 and enters the oil inlet channel 2, and then the hydraulic oil enters the distributor body 1, and finally is distributed through the distribution oil channel 36 to perform different actions, and the dust and impurities in the hydraulic oil will be blocked by the filter plate 6, thereby ensuring that the hydraulic oil entering the distributor body 1 does not contain dust and impurities, thereby greatly reducing the risk of blockage inside the distributor body 1.

[0047] As the distributor body 1 is used, more and more impurities will accumulate on the surface and in the filter holes of the filter plate 6, causing the filter holes of the filter plate 6 to be clogged. At this time, the hydraulic oil circulation effect of the filter plate 6 will become worse, causing the pressure on the right side of the mounting block 4 to gradually increase (such as Figure 4As shown), when the pressure increases, it will act on the circular plate 14, overcoming the elastic force of the first spring 15, thereby pushing the circular plate 14 to slide inside the circular groove 10, and then pushing the slide rod 11 to slide, driving the mounting plate 12 to move, thereby driving the rack 13 to move, driving the two gears 9 to rotate in the same direction, and then driving the two lead screws 7 to rotate, so that the two filter plates 6 will be driven to move upward synchronously, and the filter plate 6 located on the upper side will slowly enter the cleaning box 27 for cleaning, while the filter plate 6 located on the lower side will slowly move into the filter box 3 for filtering (as shown). Figure 4 As shown), during this process, the two filter plates 6 will move synchronously, so the flow rate of hydraulic oil from the filter box 3 into the oil inlet channel 2 will not change much, and dynamic balance can be maintained, thereby ensuring the normal operation of the distributor body 1.

[0048] When the filter plate 6 slowly enters the cleaning box 27, the sliding plate 28 will be driven to move by the connecting rod 38, and then the cleaning liquid in the liquid supply chamber 282 will be squeezed into the liquid inlet chamber 30 through the one-way liquid supply pipe 32, and then the cleaning liquid will be sprayed out through the multiple spray holes 31 to rinse the filter plate 6. In addition, the filter plate 6 will generate friction with the soft bristles 29 during the movement, which can improve the cleaning effect, thereby quickly cleaning the impurities on the surface of the filter plate 6 and the filter holes, and then the dust and impurities will be discharged through the discharge holes 39 along with the cleaning liquid.

[0049] When the upper filter plate 6 is completely moved into the cleaning box 27, the lower filter plate 6 will completely enter the filter box 3, and the circular plate 14 will move to fit the inner wall of the circular groove 10 and will be unable to move further. The circular plate 14 will push the conductive column 25 to contact the conductive sleeve 26. At this time, the circuit is connected, the first solenoid valve 21 is energized to open, and the second solenoid valve 22 is energized to close. As the dispenser body 1 is used, the filter plate 6 located below will gradually be blocked due to the accumulation of dust and impurities, causing the pressure on the right side of the mounting block 4 to continue to increase. When the pressure exceeds the pressure threshold of the one-way valve inside the one-way tube 19, the one-way valve will open, and the hydraulic oil will enter the one-way tube 19 through the pressure relief hole 18, and then enter the reset chamber 16 through the one-way tube 19, and then the hydraulic oil will push the slide plug 17 to move, driving the rack 13 to move and reset, and then driving the gear 9 to rotate in the opposite direction, driving the two When the lead screw 7 rotates in the opposite direction, the two filter plates 6 will move downward synchronously, and the cleaned filter plate 6 on the upper side will slowly enter the filter box 3, while the filter plate 6 on the lower side will slowly enter the cleaning box 27 for cleaning. When the filter plate 6 on the lower side completely enters the cleaning box 27, the mounting plate 12 will push the conductive column 25 to reset by pushing the insulating column 24, so that the conductive column 25 is separated from the conductive sleeve 26, and then the circuit is disconnected, the first solenoid valve 21 is powered off and closed, and the second solenoid valve 22 is powered off and opened, and then the filter plate 6 can be pushed upward again, and so on. During the use of the dispenser body 1, the two filter plates 6 can be filtered and cleaned alternately, ensuring effective filtration of dust and impurities while the filter plates 6 can be cleaned synchronously. There is no need to regularly maintain the filter plates 6, and the filtering performance of the filter plates 6 can be guaranteed to be normal, which is more convenient to use.
