Embodiment 1

[0033] As Figures 1-8 shown, the technical solution adopted by the present utility model is as follows: A gearbox for an automatic feeding machine includes a box body 1. A gear mechanism is installed inside the box body. A rotating block 9 is movably arranged inside the box body 1. The rotating block 9 makes both horizontal reciprocating movement and rotation inside the box body 1. A sprayer head 10 is installed at the bottom end of the rotating block 9, and a connecting rod 12 is fixedly arranged at the upper end of the rotating block 9. A lubrication assembly is arranged on the box body 1, and the lubrication assembly is communicated with the sprayer head 10 to provide lubricating oil for the sprayer head 10. A driving mechanism is arranged inside the box body 1, and the driving mechanism is in transmission cooperation with the rotating block 9 to make the rotating block 9 perform horizontal reciprocating movement. The driving mechanism is connected to the rotating block 9 through a linkage mechanism, so that while the rotating block 9 performs horizontal reciprocating movement, the rotating block 9 drives the sprayer head 10 to rotate a certain angle, thereby making the spraying of the sprayer head 10 on the gear mechanism more uniform.

[0034] The lubrication assembly includes an oil tank 2. The oil tank 2 is fixedly arranged at the upper end of the box body 1. A first oil pump 3 is fixedly installed at the upper end of the box body 1. The input end of the first oil pump 3 is connected to the output end of the oil tank 2. An oil outlet pipe is connected to the output end of the first oil pump 3. The end of the oil outlet pipe far from the first oil pump 3 passes through the rotating block 9 and is connected to the nozzle 10. Inside the box body 1, an oil storage box 19 with an opening at the upper end is fixedly arranged. The oil storage box 19 is used to store the oil for lubricating the gear mechanism. A second oil pump 4 is fixedly installed on one side of the box body 1. The oil storage box 19 is connected to the input end of the second oil pump 4 through an oil inlet pipe, and the output end of the second oil pump 4 is connected to the input end of the oil tank 2 through a connecting pipe, forming a circulating structure to reuse the oil, continuously providing lubricating oil for the nozzle 10 and avoiding waste of resources.

[0035] A filter screen 21 is slidably arranged in the oil storage box 19. The filter screen 21 is vertically arranged in the oil storage box 19. The upper end of the filter screen 21 is fixedly connected to a first pull rod 20. An opening is provided on one side of the lower part of the box body 1, and the opening is adapted to the first pull rod 20. The first pull rod 20 passes through the opening and extends outside the box body 1. A placement block is fixedly connected to one side of the lower part of the box body 1. A waste box 24 with an opening at the upper end is slidably installed up and down in the placement block. The upper end surface of the waste box 24 is below the bottom surface of the oil storage box 19. Two connecting shafts 23 are symmetrically and fixedly arranged in the waste box 24. A cover plate 25 is fixedly connected to the two connecting shafts 23. The cover plate 25 is adapted to the opening on the waste box 24 to block the waste box 24. A second pull rod 22 is fixedly connected between the upper ends of the two connecting shafts 23.

[0036] The first pull rod 20 is a return-shaped frame 1. As Figure 1 shown, the end of the first pull rod 20 far from the filter screen 21 is outside the connecting shaft 23. The first pull rod 20 is fixedly installed on the placement block through a pin, facilitating the movement of the filter screen 21 by pulling the first pull rod 20, so that the impurities in the oil storage box 19 enter the waste box 24.

[0037] A vertical plate 27 is fixedly arranged in the oil storage box 19. A trigger block 28 is arranged at the upper end of the vertical plate 27. The bottom end of the trigger block 28 is fixedly connected to an L-shaped sliding rod, and the other end of the sliding rod is fixedly connected to a floating ball 29.

A fixing block 26 is fixedly arranged at the upper end of the oil storage box 19, and a trigger switch 30 is fixedly installed on the fixing block 26. The trigger block 28 cooperates with the trigger switch 30 to energize the trigger switch 30. The trigger switch 30 is electrically connected to the second oil pump 4. When the trigger block 28 contacts the trigger switch 30, the second oil pump 4 is energized.

[0038] The driving mechanism includes a motor 5. A threaded rod 6 is rotatably arranged in the box body 1, and the axis of the threaded rod 6 is horizontally arranged. A sliding sleeve 7 is rotatably sleeved on the threaded rod 6. The sliding sleeve 7 has an I-shaped structure. The sliding sleeve 7 is threadedly connected to the threaded rod 6. The motor 5 is fixedly installed on one side of the box body 1, and the output end of the motor 5 is coaxially and fixedly connected to the threaded rod 6.

[0039] On both sides of the two ends of the sliding sleeve 7, cross bars are fixedly arranged, and vertical rods 8 are fixedly connected to the far ends of the two cross bars away from each other. Two sliding grooves are opened on the top surface of the inner wall of the box body 1, and the vertical rods 8 are slidably matched with the corresponding sliding grooves. A torsion spring 11 is sleeved on the sliding sleeve 7. One end of the torsion spring 11 is fixedly connected to the end face of the sliding sleeve 7, and the other end of the torsion spring 11 is fixedly connected to a rotating block 9.

[0040] The linkage mechanism includes a push rod 17 and a rotating sleeve 14. Fixed rings 15 are fixedly connected to both sides of the inner wall of the box body 1. The fixed rings 15 are coaxial with the threaded rod 6, and the inner diameter of the fixed rings 15 is larger than the diameter of the threaded rod 6, so the fixed rings 15 have no contact with the threaded rod 6. There are two rotating sleeves 14, and the rotating sleeves 14 are rotatably sleeved on the corresponding fixed rings 15. A guide rod 13 is fixedly connected between the two rotating sleeves 14. A connecting rod 12 is slidably connected to the guide rod 13. Connecting rings 16 are fixedly sleeved on both ends of the threaded rod 6. Grooves are opened on the connecting rings 16, and the push rod 17 is slidably arranged in the grooves. A spring 18 is fixedly connected in the grooves, and the spring 18 is fixedly connected to the push rod 17. The end face of the push rod 17 away from the threaded rod 6 consists of two inclined surfaces, and the sides away from each other of the two inclined surfaces are inclined towards the side of the threaded rod 6. The inclined surface of the push rod 17 is in abutting cooperation with the guide rod 13 to make the guide rod 13 rotate.

[0041] In summary, in the initial state, the nozzle 10 is in a vertical state, and the direction of the nozzle 10 faces the gear mechanism. The spring 18 is in a natural state.

[0042] When lubricating the gear mechanism, start the first oil pump 3. The first oil pump 3 extracts the lubricating oil in the fuel tank 2, and the lubricating oil enters the nozzle 10 through the oil outlet pipe and sprays the gear mechanism through the nozzle 10.

[0043] At the same time, start the motor 5. The output end of the motor 5 drives the threaded rod 6 to rotate. The threaded rod 6 moves the sliding sleeve 7, the sliding sleeve 7 drives the rotating block 9 to move, and the connecting rod 12 slides on the guide rod 13. The rotating block 9 drives the nozzle 10 to reciprocate horizontally to lubricate the gear mechanism. At the same time, the sliding sleeve 7 drives the vertical rod 8 to slide in the corresponding sliding groove through the cross bar.

[0044] Meanwhile, the threaded rod 6 drives the connecting ring 16 to rotate, and the connecting ring 16 drives the push rod 17 to rotate. As the push rod 17 rotates, when the push rod 17 rotates to the guide rod 13, the end of the push rod 17 away from the threaded rod 6 contacts the guide rod 13 and pushes the guide rod 13 to rotate. The guide rod 13 drives the rotating sleeve 14 and the connecting rod 12 to rotate. The connecting rod 12 makes the rotating block 9 drive the nozzle 10 to rotate, so that the nozzle 10 tilts at a certain angle, increasing the spraying range of the gear mechanism, and thus lubricating the gear mechanism more evenly. As the push rod 17 continues to rotate, the push rod 17 moves in the groove, and the spring 18 is compressed. When the spring 18 is compressed to a certain extent, the push rod 17 disengages from the guide rod 13, and the rotating block 9 returns to the initial state under the action of the torsion spring 11. At the same time, the push rod 17 returns to its original position under the action of the spring 18.

[0045] When the driving mechanism makes the rotating block 9 drive the nozzle 10 to move to the leftmost or rightmost end in the box body 1, the motor 5 rotates in reverse, making the threaded rod 6 rotate in the reverse direction. The threaded rod 6 makes the sliding sleeve 7 move in the reverse direction. At the same time, the threaded rod 6 drives the connecting ring 16 to rotate in the reverse direction. The connecting ring 16 makes the rotating block 9 drive the nozzle 10 to rotate in the reverse direction by a certain angle to lubricate the gear mechanism, so as to make the spraying of the lubricating oil more uniform, reduce the wear between the gears, and improve the service life of the gear mechanism.

[0046] The oil used to lubricate the gear mechanism enters the oil storage box 19. The filter screen 21 filters the lubricating oil in the oil storage box 19. As the oil in the oil storage box 19 increases, the oil level rises, and the floating ball 29 rises accordingly. The floating ball 29 drives the trigger block 28 to move upward through the sliding rod. When the trigger block 28 contacts the trigger switch 30, the second oil pump 4 is powered on. The second oil pump 4 extracts the oil in the oil storage box 19 through the oil inlet pipe and makes it enter the fuel tank 2 for the next use. When extracting the oil in the oil storage box 19, the filter screen 21 blocks the sediment and debris at the bottom to prevent the debris from entering the oil inlet pipe of the second oil pump 4 and causing blockage.

[0047] After the device is used for a period of time, the sediment and debris in the oil storage box 19 are cleaned. The second oil pump 4 is started to extract all the oil in the oil storage box 19. The pin is removed, and the first pull rod 20 is pulled. The first pull rod 20 drives the filter screen 21 to move towards the waste box 24. The filter screen 21 scrapes the impurities in the oil storage box 19. As it moves, the impurities enter the waste box 24. After the impurities enter the waste box 24, the second pull rod 22 is pulled upward. The second pull rod 22 drives the cover plate 25 and the waste box 24 to move upward, and the waste box 24 is taken out to clean the impurities.

[0048] After the cleaning is completed, the waste box 24 is installed in the placement block through the second pull rod 22. The filter screen 21 is moved to the leftmost end of the oil storage box 19 through the first pull rod 20. The first pull rod 20 is fixed to the placement block through the pin. Embodiment 2

[0049] As Figures 9-10 shown, a gearbox for an automatic feeder. The difference between this embodiment and Embodiment 1 lies in the different linkage mechanism for rotating the rotating block 9, and the same parts will not be described in detail here.

[0050] The linkage mechanism includes a gear 34 and a rack 35. A vertical shaft 31 is fixedly arranged at the upper end of the sliding sleeve 7. A connecting sleeve 33 is rotatably sleeved on the vertical shaft 31. A rotating rod 32 is fixedly arranged on the connecting sleeve 33. The rotating rod 32 is in abutting cooperation with the connecting rod 12. The gear 34 is fixedly sleeved on the connecting sleeve 33. The rack 35 is fixedly arranged at the upper end of the inner wall of the box body 1, and the rack 35 is in meshing cooperation with the gear 34.

[0051] In summary, during the process of the sliding sleeve 7 driving the rotating block 9 to move the spray head 10, the sliding sleeve 7 drives the vertical shaft 31 and the connecting sleeve 33 to move. The connecting sleeve 33 drives the gear 34 to move. Since the gear 34 meshes with the rack 35, the gear 34 rotates. The gear 34 rotates the connecting sleeve 33, and the connecting sleeve 33 drives the rotating rod 32 to rotate. When the rotating rod 32 rotates to the position of the connecting rod 12, the rotating rod 32 pushes the connecting rod 12 to rotate by a certain angle, and then the rotating block 9 drives the spray head 10 to rotate by a certain angle, and the torsion spring 11 deforms under force. When the rotating rod 32 is separated from the connecting rod 12, the rotating block 9 returns to the vertical state under the action of the torsion spring 11.

[0052] When the rotating block 9 moves to the leftmost or rightmost end, the motor 5 rotates in reverse, the threaded rod 6 rotates in reverse, the threaded rod 6 drives the sliding sleeve 7 to move in the reverse direction, and the sliding sleeve 7 drives the rotating block 9 to drive the spray head 10 to move in the reverse direction. The sliding sleeve 7 drives the vertical shaft 31 and the connecting sleeve 33 to move. The connecting sleeve 33 drives the gear 34 to move. The meshing of the gear 34 with the rack 35 causes the gear 34 to rotate in the reverse direction. The gear 34 rotates the connecting sleeve 33 and the rotating rod 32 in the reverse direction. The rotating rod 32 rotates the connecting rod 12 in the reverse direction by a certain angle, and then the spray head 10 tilts to the other side, and the torsion spring 11 deforms under force. When the rotating rod 32 is separated from the connecting rod 12, the rotating block 9 returns to the vertical state under the action of the torsion spring 11.
