Description

Technical Field

[0001] This utility model relates to a tracked agricultural transport vehicle gearbox, belonging to the field of gearboxes. Background Technology

[0002] When a transmission has been used for a certain period of time, the lubricating oil in the tank needs to be replaced. Maintaining smooth lubrication of the internal parts ensures smooth shifting and reduces wear. Currently, lubricating oil replacement is usually done manually. While the lubricating oil can be recycled back into the tank, debris from gear friction and dust adhering to the gears easily mix with it. The recycled lubricating oil will settle, causing impurities to accumulate at the bottom of the tank. Because the bottom of the tank is enclosed, it's impossible to observe the cleaning process immediately, requiring manual cleaning based on experience. This increases cleaning time, affects lubricating oil replacement intervals, and prolongs transmission downtime. Therefore, a tracked agricultural transport vehicle transmission design is needed that facilitates cleaning of residual impurities from the tank. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tracked agricultural transport vehicle gearbox to solve the problems mentioned in the background art. This utility model improves the cleaning efficiency of impurities inside the oil tank and reduces the situation of impurities remaining inside the oil tank.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a tracked agricultural transport vehicle gearbox, comprising a gearbox body, an oil tank mounted on one side of the gearbox body, a motor mounted on the front side of the gearbox body, a drive shaft mounted on the front side of the gearbox body, a first gear mounted on the drive shaft, a second gear mounted on the front side of the gearbox body, the second gear and the first gear meshing with each other, a scraper mounted inside the oil tank, a drive structure mounted on the scraper, and a dredging component mounted on the front side of the scraper.

[0005] Furthermore, a cable retractor is installed on the rear side of the gearbox body, and a lifting cable is installed inside the cable retractor. One end of the lifting cable is located on the outside of the cable retractor, and a handle is installed on the outside of the cable retractor. The end of the lifting cable located on the outside of the cable retractor is installed on the handle.

[0006] Furthermore, the drive structure includes a screw installed inside the oil tank. The top of the oil tank has an oil inlet, and a sealing cap is installed on the outside of the oil inlet. The bottom of the oil tank has an oil outlet located on the side of the oil tank away from the scraper, and a sealing cap is installed on the outside of the oil outlet. The unblocking component is installed on the screw. An adjusting handle is installed on one side of the screw, and the adjusting handle is located outside the oil tank. A guide rod is installed inside the oil tank, and the guide rod is arranged in a mirror array with the screw.

[0007] Furthermore, an installation slot is provided on the inner wall of the oil tank, the scraper is inserted into the installation slot, a connecting plate is installed on the upper side of the scraper, the connecting plate is threaded onto the screw, and the end of the connecting plate away from the screw is sleeved on the guide rod.

[0008] Furthermore, the unblocking component includes a connecting plate, which is installed on the upper side of the scraper. A spiral column and a sleeve are installed on the front side of the connecting plate. The spiral column and the sleeve are respectively sleeved on the screw and the guide rod. Two storage slots are symmetrically opened on the inner wall of the oil tank on the side away from the motor. The positions and sizes of the two storage slots correspond to the sleeve and the spiral column, respectively.

[0009] Furthermore, the inner diameter of the sleeve is the same as the outer diameter of the guide rod, the spiral column and the screw mesh with each other, and sealing strips are installed on both sides of the scraper, with the sealing strips fitting against the inner wall of the oil tank.

[0010] The beneficial effects of this utility model are as follows: The tracked agricultural transport vehicle gearbox of this utility model drives the screw to rotate by rotating the adjustment handle, which causes the connecting plate threaded on the screw to move axially. This drives the scraper to push the metal debris and dirt accumulated at the bottom of the oil tank toward the oil drain port, improving the cleaning efficiency of the debris at the bottom of the oil tank. Moreover, the scraper is housed in a slot on the side away from the oil drain port and is flush with the inner wall of the oil tank. As the scraper moves toward the oil drain port, it can push the impurities settled at the bottom of the oil tank toward the oil drain port as a whole, reducing the amount of debris remaining inside the oil tank.

[0011] With the cooperation of the spiral column and sleeve installed on one side of the connecting plate, as the connecting plate moves towards the oil drain port, the sleeve and spiral column can push and clean the debris accumulated on the screw and guide rod forward, reducing the probability of debris remaining inside the oil tank and reducing the situation where debris gets stuck inside the screw and prevents the connecting plate from moving.

[0021] Please see Figure 3 and Figure 4 The drive structure includes a screw 14, which is installed inside the oil tank 2. An oil inlet 10 is located at the top of the oil tank 2, and a sealing cap 9 is installed on the outside of the oil inlet 10. An oil outlet 11 is located at the bottom of the oil tank 2 on the side away from the scraper 21, and a sealing cap 12 is installed on the outside of the oil outlet 11. A drain plug is installed on the screw 14. An adjusting handle 13 is installed on one side of the screw 14, located on the outside of the oil tank 2. A guide rod 15 is installed inside the oil tank 2, and the guide rod 15 is arranged in a mirror array with the screw 14. 2. An installation slot 17 is provided on the inner wall. The scraper 21 is inserted into the installation slot 17. A connecting plate 16 is installed on the upper side of the scraper 21. The connecting plate 16 is threaded onto the screw 14. The end of the connecting plate 16 away from the screw 14 is sleeved on the guide rod 15. Through the cooperation of the guide rod 15 and the screw 14, while rotating the screw 14 to move the connecting plate 16 along the axial direction of the screw 14, the guide rod 15 can limit the range of movement of the connecting plate 16, so that the connecting plate 16 can drive the scraper 21 to move forward smoothly along the bottom of the oil tank 2.

[0022] Please see Figure 4 and Figure 5 The unblocking component includes a connecting plate 16, which is installed on the upper side of the scraper 21. A spiral column 20 and a sleeve 18 are installed on the front side of the connecting plate 16. The spiral column 20 and the sleeve 18 are respectively sleeved on the screw 14 and the guide rod 15. Two collection slots 19 are symmetrically opened on the inner wall of the oil tank 2 away from the motor 3.

The inner diameter of the sleeve 18 is the same as the outer diameter of the guide rod 15. The spiral column 20 and the screw 14 mesh with each other. Sealing strips 22 are installed on both sides of the scraper 21. The sealing strips 22 are in close contact with the inner wall of the oil tank 2. Through the cooperation of the scraper 21 and the sealing strips 22, the sealing strips 22 are made of rubber and can deform. During the movement of the scraper 21, the two sides of the scraper 21 can be tightly in contact with the inner wall of the oil tank 2, reducing the situation where impurities remain in the gap between the scraper 21 and the inner wall of the oil tank 2.

[0023] Detailed implementation: By rotating the adjusting handle 13, the screw 14 is rotated, causing the connecting plate 16 threaded on the screw 14 to move axially. This drives the scraper 21 to push the metal debris and dirt accumulated at the bottom of the oil tank 2 toward the drain port 11, improving the cleaning efficiency of the debris at the bottom of the oil tank 2. The scraper 21 is housed in the slot 17 on the side away from the drain port 11, flush with the inner wall of the oil tank 2. As the scraper 21 moves toward the drain port 11, it can push the impurities accumulated at the bottom of the oil tank 2 toward the drain port 11, reducing the amount of debris remaining inside the oil tank 2. Through the cooperation of the spiral column 20 and the sleeve 18 installed on one side of the connecting plate 16, as the connecting plate 16 moves toward the drain port 11, the sleeve 18 and the spiral column 20 can push the debris accumulated on the screw 14 and the guide rod 15 forward to clean it, reducing the probability of debris remaining inside the oil tank 2 and reducing the situation where debris gets stuck inside the screw 14 and prevents the connecting plate 16 from moving.
