[0002] The plow blade hub unit is a specially designed hub unit structure, which is mainly applied to equipment or machinery that requires plow blades for operation.

[0003] At present, when some existing plow blade hub units need lubrication, users may need to manually apply lubricating oil or disassemble some parts for lubrication. This operation is not only cumbersome, but may even damage the parts due to improper operation during the disassembly process. In view of this, we propose a plow blade hub unit with replaceable lubricating oil. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a plow blade hub unit with replaceable lubricating oil, which can solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides a plow blade hub unit with replaceable lubricating oil, including a shaft body. The shaft body penetrates through the frame arm and is fixedly connected with the frame arm. The shaft body penetrates through a connecting piece and is sleeved with the connecting piece. The connecting piece is fixedly connected with a flange plate. An adjusting device is arranged inside the shaft body, and the adjusting device includes:

[0006] A fixed block, which is fixedly connected with the inner wall of the shaft body, and a guide rod is fixedly connected to the outer wall of the fixed block;

[0007] A sliding block, which is slidably connected with the inner wall of the shaft body. The sliding block penetrates through the fixed block and is slidably connected with the fixed block. The sliding block is provided with a cavity, and a sphere is arranged inside the cavity. The sliding block is penetrated by the guide rod and is slidably connected with the guide rod. The end of the guide rod is fixedly connected with the sphere;

[0008] A spring, one end of which is fixedly connected with the outer wall of the sliding block, and the other end of which is fixedly connected with the inner wall of the shaft body.

[0009] Preferably, the shaft body is provided with an oil storage groove and a threaded groove, and a piston block is slidably connected to the inner wall of the oil storage groove.

[0010] Preferably, a connecting rod is fixedly connected to the outer wall of the piston block. One end of the connecting rod away from the piston block is rotatably connected with a threaded block, and a hexagonal opening is arranged in the threaded block. By cooperating with an L-shaped hexagonal rod, the piston block can be moved inside the oil storage groove. The threaded block is threadedly connected with the threaded groove.

[0011] Preferably, the shaft body is provided with an annular groove and an oblique groove, and the oblique grooves are provided in multiple groups, and the multiple groups of oblique grooves are evenly distributed on the outer wall of the shaft body.

[0012] Preferably, a sleeve is fixedly connected to the inner wall of the connecting piece, and the sleeve is connected to the shaft body via a ball bearing.

[0013] Preferably, an oil filling groove is provided on the outer wall of the shaft body, and the oil filling groove is sealingly connected with a sealing plug for sealing the oil storage tank.

[0014] The utility model provides a plow hub unit with replaceable lubricating oil, which has the following beneficial effects:

[0015] (1) The lubricant-replaceable plow hub unit has an oil filling groove and a sealing plug on the shaft body, which can easily inject lubricant into the oil storage tank. When lubricant needs to be added, the L-shaped hexagonal rod is connected to the threaded block and rotated to drive the piston block to slide in the oil storage tank to add lubricant. This design does not require a complicated disassembly process and can quickly complete the lubricant replenishment without affecting the overall structure of the device, effectively improving maintenance efficiency, reducing equipment wear and failure caused by insufficient lubricant, and extending the service life of the plow hub unit.

[0016] (2) For the plow hub unit with replaceable lubricating oil, after lubrication is completed, the threaded block is rotated in the opposite direction to return the piston block to its original position. At this time, the pressure inside the oil storage tank is reduced, and the sliding block returns to its original position under the elastic force of the spring. The ball blocks the through hole again, effectively preventing the leakage of the lubricating oil. This not only improves the utilization rate of the lubricating oil, but also avoids the safety hazards and environmental pollution caused by the leakage of the lubricating oil.

[0028] Please refer to Figure 1 - Figure 6 , the present utility model provides a plow blade hub unit with replaceable lubricating oil, which includes a shaft body 1. An oil injection groove is provided on the outer wall of the shaft body 1, and a sealing plug is hermetically connected to the oil injection groove. An annular groove 102 and an inclined groove 101 are provided in the shaft body 1. Multiple groups of inclined grooves 101 are provided, and the multiple groups of inclined grooves 101 are evenly distributed on the outer wall of the shaft body 1. The shaft body 1 penetrates through the frame arm 2 and is fixedly connected to the frame arm 2. The shaft body 1 penetrates through the connecting piece 3 and is sleeved with the connecting piece 3. A sleeve 5 is fixedly connected to the inner wall of the connecting piece 3, and the sleeve 5 is connected to the shaft body 1 through balls 51. The connecting piece 3 is fixedly connected to the flange 4, and an adjusting device is provided in the shaft body 1

[0029] In an embodiment of the present utility model, in order to add lubricating oil to the ball 51, specifically, the adjusting device includes a fixed block 110, the fixed block 110 is fixedly connected to the inner wall of the shaft body 1, a guide rod 112 is fixedly connected to the outer wall of the fixed block 110, a sliding block 109 is slidably connected to the inner wall of the shaft body 1, the sliding block 109 penetrates the fixed block 110 and is slidably connected to the fixed block 110, a cavity 111 is formed in the sliding block 109, a sphere 113 is arranged inside the cavity 111, the sliding block 109 is penetrated by the guide rod 112 and is slidably connected to the guide rod 112, the end of the guide rod 112 is fixedly connected to the sphere 113, one end of a spring 108 is fixedly connected to the outer wall of the sliding block 109, and the other end of the spring 108 is fixedly connected to the inner wall of the shaft body 1;

[0030] Furthermore, the shaft body 1 is provided with an oil storage groove 103 and a threaded groove 105, a piston block 104 is slidably connected to the inner wall of the oil storage groove 103, a connecting rod 106 is fixedly connected to the outer wall of the piston block 104, a threaded block 107 is rotatably connected to one end of the connecting rod 106 away from the piston block 104, and the threaded block 107 is in threaded connection with the threaded groove 105;

[0031] In the present utility model, during use, first open the sealing plug, inject lubricating oil into the oil storage groove 103 through the oil injection groove, and then seal the oil injection groove with the sealing plug. When the device is used for a long time and lubricating oil needs to be added, at this time, take out the L-shaped hexagonal rod and dock it with the threaded block 107, and then rotate the threaded block 107. During this process, the piston block 104 will slide on the inner wall of the oil storage groove 103.
