[0038] Specifically, by using the mounting hole 1 26 and the mounting hole 2 27, the mounting block 1 1 and the mounting block 2 5 can be respectively installed on the front frame and the rear frame, so that the front frame and the rear frame can be hinged, and the front frame and the rear frame can rotate relative to each other in the horizontal plane, thereby realizing the steering of the scraper loader, allowing the scraper loader to move flexibly in a narrow or complex working environment, thereby improving the working efficiency. In addition, since there are two hinge points, this makes the scraper loader more stable when bearing a large load, can better maintain the stability of the vehicle body, and reduce the safety hazards caused by bumps or tilts.

[0046] A second motor 16 is fixedly connected to one side of the fixing ring 12 , and an output end of the second motor 16 is fixedly connected to the gear 15 .

[0047] Specifically, when the existing central hinge structure for underground scrapers is in use, the lubricating oil in the storage bin can be poured out, and the oil tank and the oil outlet pipe can cooperate with each other to achieve the lubrication effect between the connecting parts. However, at low temperatures, the lubricating oil may become viscous and difficult to flow, causing the lubricating oil to agglomerate inside the oil tank, thereby blocking the oil tank and affecting subsequent lubrication work. In addition, the lubricating oil may be contaminated by impurities such as dust and metal debris during production, storage and use. These impurities may also accumulate in the lubricating oil to form agglomerates, which also causes the oil tank to be blocked.

[0048] Therefore, in order to avoid the above problems, when the present embodiment is in use, when the connecting piece needs to be lubricated, the lubricating oil in the lubricating oil tank 6 can be pumped out by the pump body 11, and after passing through the long tube 10 and the hose 9, the lubricating oil can enter the gap between the connecting groove 32 and the connecting ring 28 from the oil filling hole 17. At the same time, the lubricating oil can flow evenly from the multiple oil outlets 31 to the surface of the connecting shaft 3, so as to achieve uniform lubrication of the connecting piece, thereby helping to improve the stability and sensitivity of the device.

[0049] The sealing plate 7 can be driven to rotate by the motor 18 after a period of lubrication, so that the sealing plate 7 that originally covered the connecting groove 32 can be removed, and the threaded tube 22 can be driven to rotate by the motor 31, so that the threaded rod 23 can move in the inner cavity of the threaded tube 22, and the sliding rod 24 can slide in the inner cavity of the sleeve 20, so that the scraper ring 13 can slide in the inner cavity of the connecting groove 32 to push the agglomerates attached to the inner wall of the connecting groove 32 and the outer ring surface of the connecting ring 28 to move them out of the connecting groove 32. At the same time, when the scraper ring 13 moves, the scraper block 18 will also be in close contact with the inner wall of the oil outlet 31 under the action of the spring 19, so that the scraper block 18 can be used to push the agglomerates on the inner wall of the oil outlet 31, so that the agglomerates inside the lubricating oil flow channel can be removed under the action of the scraper ring 13 and the scraper block 18, so as to avoid the agglomerates blocking the lubricating oil flow channel and ensure the smooth progress of subsequent lubrication work.

[0050] Furthermore, since the agglomerates may have a certain degree of stickiness, the agglomerates may adhere to the surfaces of the scraper ring 13 and the scraper block 18, resulting in incomplete cleaning. When the scraper ring 13 and the scraper block 18 are reset, the agglomerates may return to the connecting groove 32 and continue to block the flow channel of the lubricating oil. Therefore, in order to avoid this problem, when the scraper ring 13 is completely separated from the connecting ring 28, the motor 2 16 can be used to drive the gear 15 to rotate, so that the gear ring 14 and the scraper ring 13 rotate at the same time. When the scraper ring 13 rotates, the centrifugal force Under the action, the lumps adhered to the surfaces of the scraper ring 13 and the scraper block 18 are thrown off, thereby realizing self-cleaning of the lumps on the surfaces of the scraper ring 13 and the scraper block 18, and avoiding the situation that when the scraper ring 13 and the scraper block 18 are reset, the lumps adhered to the surfaces of the scraper ring 13 and the scraper block 18 return to the connecting groove 32 and continue to block the flow channel of the lubricating oil. In addition, since one side of the scraper block 18 is a slope, when the scraper block 18 is reset, the scraper block 18 will not be unable to reset due to mutual obstruction between the scraper block 18 and the connecting shaft 3.

[0051] Working principle: by using the mounting hole 1 26 and the mounting hole 2 27, the mounting block 1 1 and the mounting block 2 5 can be respectively mounted on the front frame and the rear frame, so that the front frame and the rear frame can be hinged, so that the front frame and the rear frame can rotate relative to each other in the horizontal plane, thus realizing the steering of the scraper loader, so that the scraper loader can move flexibly in a narrow or complex working environment, thus improving the working efficiency. In addition, since there are two hinge points, the scraper loader is more stable when bearing a large load, and can better maintain the stability of the vehicle body, reducing the potential safety hazards caused by bumps or tilts. When the connector needs to be lubricated, the pump body 11 can be used to extract the lubricating oil in the lubricating oil tank 6, and after passing through the long tube 10 and the hose 9, the lubricating oil can be pumped out from the oil filling hole 17 enters into the gap between the connecting groove 32 and the connecting ring 28. At the same time, the lubricating oil can flow evenly from the multiple oil outlets 31 to the surface of the connecting shaft 3 to achieve uniform lubrication of the connecting parts, thereby helping to improve the stability and sensitivity of the device; and after each lubrication period, the sealing plate 7 can be driven to rotate by the motor 1 8 to remove the sealing plate 7 that originally covered the connecting groove 32, and the threaded cylinder 22 can be driven to rotate by the motor 3 21 to move the threaded rod 23 in the inner cavity of the threaded cylinder 22, the sliding rod 24 slides in the inner cavity of the sleeve 20, and the scraper ring 13 slides in the inner cavity of the connecting groove 32 to push the agglomerates attached to the inner wall of the connecting groove 32 and the outer ring surface of the connecting ring 28 to remove them from the connecting groove 32. At the same time, When the scraper ring 13 moves, the scraper block 18 will also be in close contact with the inner wall of the oil outlet 31 under the action of the spring 19, and the scraper block 18 can be used to push the agglomerates on the inner wall of the oil outlet 31, so that the agglomerates inside the lubricating oil flow channel can be removed under the action of the scraper ring 13 and the scraper block 18, thereby avoiding the blockage of the lubricating oil flow channel by the agglomerates, and ensuring the smooth progress of subsequent lubrication work; and, since the agglomerates may have a certain viscosity, the agglomerates may adhere to the surfaces of the scraper ring 13 and the scraper block 18, resulting in incomplete removal. When the scraper ring 13 and the scraper block 18 are reset, these agglomerates may return to the connecting groove 32 and continue to block the flow channel of the lubricating oil. Therefore, in order to avoid this When the scraper ring 13 is completely separated from the connecting ring 28, the motor 16 can be used to drive the gear 15 to rotate, so that the gear ring 14 and the scraper ring 13 rotate at the same time. When the scraper ring 13 rotates, the agglomerates adhering to the surfaces of the scraper ring 13 and the scraper block 18 will be thrown off under the action of centrifugal force, thereby realizing self-cleaning of the agglomerates on the surfaces of the scraper ring 13 and the scraper block 18, and avoiding the agglomerates adhering to the surfaces of the scraper ring 13 and the scraper block 18 when the scraper ring 13 and the scraper block 18 are reset, causing these agglomerates to return to the connecting groove 32 and continue to block the flow channel of the lubricating oil. In addition, since one side of the scraper block 18 is a slope, when the scraper block 18 is reset, the scraper block 18 will not be unable to reset due to mutual obstruction between the scraper block 18 and the connecting shaft 3.
