Description

TECHNICAL FIELD

[0001] The utility model relates to transmission shaft technical field especially relates to a high strength agricultural machinery transmission shaft protection sleeve. BACKGROUND

[0002] The transmission shaft is a high-speed rotating body with few supports, and therefore its dynamic balance is very important. Generally, the transmission shaft is subjected to dynamic balance test before leaving the factory and is adjusted on a balancing machine. For a car with front-mounted engine and rear-wheel drive, the transmission shaft is the shaft that transmits the rotation of the transmission to the main reducer. The transmission shaft can be several sections, and the sections can be connected by universal joints. The transmission shaft is an important component for transmitting power in the automobile drive train. It works with the transmission and drive axle to transmit power from the engine to the wheels, enabling the car to generate driving force. Special-purpose automobile transmission shafts are mainly used on tank trucks, refueling trucks, water spraying trucks, sewage suction trucks, manure suction trucks, fire trucks, high-pressure cleaning trucks, road wrecker trucks, overhead working trucks, garbage trucks, and other vehicle models. When exposed to air, the transmission shaft is easily eroded by external sand and moisture, reducing the flexibility of the relative sliding between the transmission shafts. In addition, when adding lubricating oil during use, the transmission shaft needs to be disassembled from the equipment, which is relatively complex to operate.

[0003] A transmission shaft protection sleeve structure is disclosed in Chinese Utility Model Patent No. CN220168385U, which relates to the technical field of transmission shafts. The structure includes a transmission shaft, a telescopic tube attached to the surface of the transmission shaft, first supports connected to the two sides of the telescopic tube, a manual valve connected to the top of the first supports, a lubricating oil pipeline connected to the top of the manual valve, and a lubricating oil tank connected to the top of the lubricating oil pipeline. The utility model connects first supports to the two sides of the first supports and connects a manual valve to the top of the first supports. When lubricating the transmission shaft, the worker manually operates the manual valve to open it, allowing the lubricating oil to flow from the lubricating oil tank into the lubricating oil pipeline connected to the bottom of the lubricating oil tank. The lubricating oil is then dripped into the circular holes on the surface of the telescopic tube through one end of the lubricating oil pipeline, eliminating the need to disassemble the transmission shaft for lubrication.

[0004] According to the related technology in the above, the inventors believe that the following defects exist: The above device stores lubricating oil in a lubricating oil tank and adds lubricating oil to the transmission shaft through a lubricating oil pipeline connected to the telescopic tube. This setup makes it difficult for workers to determine how much lubricating oil has been added to the transmission shaft. Since a fixed amount of lubricating oil needs to be added to the transmission shaft during vehicle maintenance, the worker can only add lubricating oil to the transmission shaft based on experience, resulting in a poor user experience. UTILITY MODEL CONTENTS

[0005] To solve the above problems, the utility model provides a high-strength agricultural machinery transmission shaft protection sleeve.

[0006] The above technical purpose of the utility model is realized through the following technical scheme: a high-strength agricultural machinery transmission shaft protective sleeve, comprising a transmission shaft main body, a first support arranged on the side wall of the transmission shaft main body, a second support arranged on the first support, a lubricating oil tank arranged on the second support, a lubricating oil pipeline connected with the lubricating oil tank and a hand valve arranged on the lubricating oil tank, a sliding groove is arranged on the side wall of the lubricating oil tank, a sliding slot is arranged on the inner wall of the lubricating oil tank, and an auxiliary assembly for assisting workers to add lubricating oil is arranged on the lubricating oil tank.

[0007] When the workers need to maintain the transmission shaft, the workers need to add a certain amount of lubricating oil into the transmission shaft main body.

[0008] Further, the auxiliary assembly comprises a sliding block slidingly arranged in the sliding slot, a sliding plate fixed on the side wall of the sliding block, a limiting slot is arranged on the side wall of the sliding plate, the auxiliary assembly further comprises a limiting plate slidingly arranged in the limiting slot, a first magnet block embedded on the side wall of the sliding plate close to the sliding groove, a sliding block slidingly arranged in the sliding groove, a second magnet block embedded on the side wall of the sliding block close to the limiting plate, and a driving device arranged on the sliding plate for driving the limiting plate, and the first magnet block and the second magnet block are mutually adsorbed.

[0009] When the workers need to add lubricating oil into the transmission shaft main body, since the first magnet block and the second magnet block are mutually adsorbed, the workers only need to slide the sliding block, so that the sliding plate moves with the sliding block, thereby adjusting the height of the sliding plate.

[0010] Further, the side wall of the limiting plate is fixed with a tension spring, and the other end of the tension spring is fixed with the inner wall of the limiting slot.

[0011] Through the above technical scheme, when the limiting plate is not subjected to external force, the limiting plate is completely moved into the limiting slot under the action of the tension spring, thereby reducing the probability that the limiting plate interferes with the sliding plate at this time.

[0012] Further, the driving device comprises a magnet rod arranged on the limiting plate near the side wall of the sliding block and an electromagnet arranged on the inner wall of the limiting groove.

[0013] By adopting the above technical scheme, when the staff moves the sliding plate to a suitable height, the staff only needs to turn on the electromagnet, so that the electromagnet repels the magnet rod, so that the limiting plate moves away from the sliding block under the action of the electromagnet, and then the limiting plate abuts against the inner wall of the lubricating oil tank.

[0014] Further, the upper surface of the lubricating oil tank is provided with a communication groove in communication with the sliding groove, and a communication block is slidably arranged in the communication groove.

[0015] By adopting the above technical scheme, the communication block improves the stability of the sliding block, thereby reducing the probability of mutual separation of the sliding block and the lubricating oil tank when the sliding block is adsorbed on the lubricating oil tank.

[0016] Further, the side wall of the sliding block is provided with a fixing bolt for limiting the sliding block.

[0017] By adopting the above technical scheme, when the sliding block moves to a suitable height, the staff only needs to rotate the fixing bolt, so that the fixing bolt abuts against the inner wall of the sliding groove, so that the sliding block remains stable, and the staff does not need to continuously apply a force to the sliding block to keep it stable, thereby reducing the operation difficulty of the staff.

[0018] Further, the side wall of the limiting plate away from the extension spring is fixed with a silica gel piece.

[0019] By adopting the above technical scheme, the silica gel piece improves the frictional resistance between the limiting plate and the inner wall of the lubricating oil tank, thereby improving the stability of the limiting plate when abutting against the inner wall of the lubricating oil tank, and improving the use experience of the staff.

[0020] Further, the side wall of the second support is provided with a control switch, and the control switch is electrically connected with the electromagnet.

[0021] In summary, the utility model has the following beneficial effects:

At this time, the staff only need to slide the sliding block, the height of the sliding plate can be adjusted, so as to control the oil amount of the lubricating oil under the sliding plate. When the sliding plate moves to the appropriate height, the staff only need to open the driving device, the limiting plate can be tightly contacted with the inner wall of the lubricating oil tank under the action of the driving device, so as to separate the lubricating oil tank with the limiting plate and the sliding plate. Then, the staff only need to open the hand valve, the lubricating oil under the sliding plate can flow into the transmission shaft body through the lubricating oil pipeline, so as to maintain the transmission shaft;

[0023] 2、in this application, when the staff need to add lubricating oil into the transmission shaft body, because the first magnet block and the second magnet block are mutually adsorbed, the staff only need to slide the sliding block, the sliding plate can move with the sliding block, so as to adjust the height of the sliding plate. When the sliding plate moves to the appropriate height, the staff only need to open the driving device, the limiting plate can move away from the sliding block, so as to tightly contact with the inner wall of the lubricating oil tank, and then separate the lubricating oil tank with the limiting plate and the sliding plate;

[0024] 3、in this application, when the staff move the sliding plate to the appropriate height, the staff only need to open the electromagnet, the electromagnet can repel the magnet rod, so that the limiting plate moves away from the sliding block under the action of the electromagnet, and then tightly contacts with the inner wall of the lubricating oil tank.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] like Figures 1-6 As shown in the illustration, this application discloses a high-strength protective sleeve for an agricultural machinery drive shaft, comprising a drive shaft body 1, a first bracket 11, a second bracket 2, a lubricating oil tank 21, a lubricating oil pipe 3, a manual valve 31, auxiliary components 5, a tension spring 7, a connecting block 8, a fixing bolt 81, a silicone sheet 82, and a control switch 9. The first bracket 11 is mounted on the side wall of the drive shaft body 1, and the second bracket 2 is mounted on the first bracket 11. The lubricating oil tank 21 is a hollow rectangular structure and is mounted on the second bracket 2. The lubricating oil pipe 3 is a cylindrical structure and is connected to the lubricating oil tank 21, and the manual valve 31 is mounted on the lubricating oil tank 21.

[0034] A sliding groove 4 is formed on the side wall of the lubricating oil tank 21, and a sliding groove 41 is formed on the inner wall of the lubricating oil tank 21. An auxiliary component 5 is set on the lubricating oil tank 21 to assist the operator in adding lubricating oil. The auxiliary component 5 includes a slider 51, a sliding plate 52, a limiting plate 53, a first magnet block 54, a sliding block 55, a second magnet block 56, and a driving device 6. The slider 51 is a rectangular block structure and is slidably disposed in the sliding groove 41. The sliding plate 52 is a rectangular plate structure and is fixed to the side wall of the slider 51. A limiting groove 57 is formed on the side wall of the sliding plate 52, and the limiting plate 53 is a rectangular plate structure and is slidably disposed in the limiting groove 57. The first magnet block 54 is a block structure and is embedded in the side wall of the sliding plate 52 near the sliding groove 4. The sliding block 55 is a rectangular block structure and is slidably disposed in the sliding groove 4. The second magnet block 56 has a block structure and is embedded in the side wall of the sliding block 55 near the limiting plate 53. The first magnet block 54 and the second magnet block 56 attract each other.

[0035] The driving device 6 is arranged on the sliding plate 52 and used for driving the limiting plate 53. The driving device 6 comprises a magnet rod 61 and an electromagnet 62. The magnet rod 61 is in a circular rod structure. The magnet rod 61 is arranged on the side wall of the limiting plate 53 close to the sliding block 55. The electromagnet 62 is arranged on the inner wall of the limiting groove 57.

[0036] When the staff moves the sliding plate 52 to a suitable height, the staff only needs to turn on the electromagnet 62, so that the electromagnet 62 repels the magnet rod 61, and the limiting plate 53 moves away from the sliding block 55 under the action of the electromagnet 62, and then the limiting plate 53 abuts against the inner wall of the lubricating oil tank 21.

[0037] One end of the tension spring 7 is fixed on the side wall of the limiting plate 53, and the other end of the tension spring 7 is fixed with the inner wall of the limiting groove 57. When the limiting plate 53 is not subjected to external force, the limiting plate 53 is completely moved into the limiting groove 57 under the action of the tension spring 7, thereby reducing the probability that the limiting plate 53 interferes with the sliding plate 52 at this time.

[0038] The upper surface of the lubricating oil tank 21 is provided with a communication groove 71 which is in communication with the sliding groove 4. The communication block 8 is in a rectangular block structure.

The communication block 8 improves the stability of the sliding block 55, thereby reducing the probability that the sliding block 55 is separated from the lubricating oil tank 21 when it is adsorbed on the lubricating oil tank 21.

[0039] The fixing bolt 81 is arranged on the side wall of the sliding block 55 and used for limiting the sliding block 55. When the sliding block 55 moves to a suitable height, the staff only needs to rotate the fixing bolt 81, so that the fixing bolt 81 abuts against the inner wall of the sliding groove 4, thereby keeping the sliding block 55 stable, and the staff does not need to continuously apply a force to keep the sliding block 55 stable, thereby reducing the operation difficulty of the staff.

[0040] In order to improve the use experience of the staff, the side wall of the limiting plate 53 away from the tension spring 7 is fixed with a silica gel piece 82. The silica gel piece 82 improves the frictional resistance between the limiting plate 53 and the inner wall of the lubricating oil tank 21, thereby improving the stability of the limiting plate 53 when it abuts against the inner wall of the lubricating oil tank 21, and improving the use experience of the staff.

[0041] The control switch 9 is arranged on the side wall of the second support 2 and electrically connected with the electromagnet 62.

[0042] The use principle of the high-strength protection sleeve for agricultural machinery transmission shaft in the embodiment is as follows: when the staff needs to maintain the transmission shaft, the staff needs to add a certain amount of lubricating oil into the transmission shaft body 1. At this time, the staff only needs to slide the sliding block 55 to adjust the height of the sliding plate 52, thereby controlling the oil amount of the lubricating oil below the sliding plate 52. When the sliding plate 52 is moved to a suitable height, the staff only needs to open the driving device 6 to make the limiting plate 53 abut against the inner wall of the lubricating oil tank 21 under the action of the driving device 6, thereby making the limiting plate 53 and the sliding plate 52 cooperate to separate the lubricating oil tank 21. Then, the staff only needs to open the hand valve 31 to make the lubricating oil below the sliding plate 52 flow into the transmission shaft body 1 through the lubricating oil pipeline 3, thereby maintaining the transmission shaft.

[0043] The preferred embodiments of the utility model are described above, and the protection scope of the utility model is not limited to the above-mentioned embodiments. Any technical scheme falling within the concept of the utility model belongs to the protection scope of the utility model. It should be noted that, for ordinary skilled persons in the technical field, some improvements and decorations without departing from the principle of the utility model are also considered as the protection scope of the utility model.
