DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides a front bridge section component of a frame of a corn harvester, including a rod 1, a bearing seat 23 is fixed on the rod 1, and the top of the bearing seat 23 is connected to a fixing plate 6 through a buffer structure. In some embodiments of the present application, the buffer structure includes a buffer pad 24 fixedly connected to the top of the bearing seat 23 and a connecting rod 25 fixedly connected to the bottom of the fixing plate 6, the top of the buffer pad 24 is fixedly connected to the bottom of the fixing plate 6, and the bottom end of the connecting rod 25 is connected to the top of the bearing seat 23 through a buffer sheet and a spring. It can be seen from the above description that when the front bridge section component of the frame is connected to the frame of the corn harvester through the fixing plate 6, the buffer pad 24, the buffer sheet and the spring can reduce the mutual influence between the front bridge section component of the frame and the frame of the corn harvester, thereby improving the driving experience.

[0026] In some embodiments of the present application, the buffer pad 24 and the buffer sheet are both made of rubber.

[0027] The end of the rod 1 is connected to a wheel hub through a steering knuckle 2. The wheel hub includes a fixed sleeve 3 fixedly connected to the outer ring of the end of the steering knuckle 2 away from the rod 1 and a rotating part 5 movably connected to the middle part of the end of the steering knuckle 2 away from the rod 1. The rotating part 5 is connected to the fixed sleeve 3 through a bearing 4. A brake structure is provided in the inner cavity of the fixed sleeve 3, and the brake structure is used to brake the rotating part 5. In some embodiments of the present application, the brake structure includes a brake pad 14 connected to the fixed sleeve 3 through a hydraulic rod 9 and a friction disc 17 fixedly connected to the end of the rotating part 5 close to the steering knuckle 2. Under the action of the hydraulic rod 9, the distance between the brake pad 14 and the friction disc 17 can change. When the brake pad 14 is tightly fitted with the friction disc 17, the friction resistance between the brake pad 14 and the friction disc 17 can prevent the rotating part 5 from rotating, thereby achieving the braking of the rotating part 5.

[0028] The inner cavity of the fixed sleeve 3 is provided with a lubricating structure 1 for lubricating the bearing 4. The lubricating structure 1 includes a sealing ring 13 fixedly connected to the fixed sleeve 3. The lubricating structure 1 is separated from the brake structure by the sealing ring 13, and one end of the sealing ring 13 is fixedly connected to the inner wall of the fixed sleeve 3, and the other end of the sealing ring 13 is movably connected to the rotating part 5. In some embodiments of the present application, the sealing ring 13 is in contact with the rotating part 5 through a ball. Through the setting of the sealing ring 13, the sealing ring 13 can intercept the lubricating oil to prevent the lubricating oil from contaminating the brake structure.

[0029] The lubrication structure 1 also includes an oil storage box 12 fixed on the inner wall of the fixed sleeve 3, an extrusion plate 22 in contact with the end of the oil storage box 12 away from the bearing 4, an electromagnet 21 fixed to the extrusion plate 22, and an electromagnet 2 7 fixed to the fixed sleeve 3; oil spray ports are evenly arranged at one end of the inner cavity of the oil storage box 12 close to the bearing 4, the extrusion plate 22 is magnetically connected to the sealing ring 13, and when powered on, the electromagnet 2 7 and the electromagnet 21 are in a state of magnetic repulsion.

[0030] From the above description, it can be known that when the bearing 4 needs to be lubricated, the electromagnet 1 21 and the electromagnet 2 7 are both energized, and the magnetic repulsive force between the electromagnet 1 21 and the electromagnet 2 7 causes the extrusion plate 22 to squeeze the oil storage box 12, and the lubricating oil in the oil storage box 12 is squeezed out. The lubricating oil can be sprayed onto the bearing 4 to achieve lubrication of the bearing 4. When the power is off, the extrusion plate 22 and the sealing ring 13 are magnetically attracted, and the position of the extrusion plate 22 is fixed, which is convenient for the reuse of the lubrication structure 1.

[0031] In some embodiments of the present application, the sealing ring 13 is made of metal iron, and a permanent magnet is fixed to one end of the extrusion plate 22 connected to the sealing ring 13.

[0032] The outer ring of the friction disc 17 is fixedly connected with an oil suction ring 15. Through the setting of the oil suction ring 15, the oil suction ring 15 can absorb the leaked lubricating oil to prevent the lubricating oil from contaminating the brake disc.

[0033] The fixing sleeve 3 is provided with an oil filling passage connected to the inner cavity of the oil storage box 12 , and one end of the oil filling passage away from the oil storage box 12 is sealed by a sealing plug 8 , so as to facilitate the filling of lubricating oil into the oil storage box 12 .

[0034] A second lubricating structure for lubricating the connection between the rotating part 5 and the steering knuckle 2 is provided in the inner cavity of the fixed sleeve 3 .

[0035] The lubrication structure 2 includes a sealing ring 2 18 fixedly connected to the fixed sleeve 3. The lubrication structure 2 is separated from the brake structure by the sealing ring 2 18. One end of the sealing ring 2 18 is fixedly connected to the inner wall of the fixed sleeve 3, and the other end of the sealing ring 2 18 is movably connected to the rotating part 5. In some embodiments of the present application, the sealing ring 2 18 is connected to the rotating part 5 through a ball bearing.

[0036] Another oil suction ring 15 is fixed to the inner wall of the friction disc 17. In some embodiments of the present application, the oil suction ring 15 is made of oil-absorbing cotton.

[0037] The lubrication structure 2 also includes an oil storage ring 16 fixedly connected to the sealing ring 2 18, an oil squeezing ring 20 magnetically connected to the sealing ring 2 18, an electromagnet 3 19 fixedly connected to the oil squeezing ring 20, and an electromagnet 4 11 fixedly connected to the end of the sealing ring 2 18 away from the oil storage ring 16. The inner wall of the oil squeezing ring 20 is evenly provided with oil injection ports, and when powered on, the electromagnet 3 19 and the electromagnet 4 11 are in a state of magnetic repulsion.

[0038] From the above description, it can be known that the repulsive force generated when both the electromagnet three 19 and the electromagnet four 11 are energized can be used to enable the oil squeeze ring 20 to squeeze out the lubricating oil in the oil storage ring 16, and the squeezed lubricating oil is sprayed on the connection portion between the rotating part 5 and the steering knuckle 2, thereby facilitating the rotation of the rotating part 5.

[0039] In some embodiments of the present application, the material of the second sealing ring 18 is metal iron, and a permanent magnet is fixed at the portion where the oil squeeze ring 20 and the second sealing ring 18 are connected.

[0040] Another lubrication structure 2 is provided on the outer side of the movable part of the above-mentioned steering knuckle 2, and the movable part is lubricated by the lubrication structure 2. The other lubrication structure 2 is fixed on the steering knuckle 2 by conventional technical means, which will not be described in detail here.

[0041] The sealing ring 18 is provided with a lubricating oil filling passage which is connected with the inner cavity of the oil storage ring 16 , and one end of the lubricating oil filling passage away from the oil storage ring 16 is sealed by a plug.

[0042] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to actual conditions, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0043] In summary: when the front bridge section component of the frame of the corn harvester is in use, the buffer pad 24, the buffer sheet and the spring can all reduce the mutual influence between the front bridge section component of the frame and the frame of the corn harvester, thereby improving the driving experience. The bearings in the front bridge section component of the frame can be lubricated by the lubrication structure 1, and the rotating parts in the front bridge section component of the frame can be lubricated by the lubrication structure 2, thereby improving the convenience of lubrication of the front bridge section component of the frame. When lubricating the bearings, both the electromagnet 1 21 and the electromagnet 2 7 are energized, and the magnetic repulsive force between the electromagnet 1 21 and the electromagnet 2 7 causes the extrusion plate 22 to squeeze the oil storage box 12, and the lubricating oil in the oil storage box 12 is squeezed out, and the lubricating oil can be sprayed onto the bearing 4 to achieve lubrication of the bearing 4. When the power is off, the extrusion plate 22 and the sealing ring 13 are magnetically attracted to each other, and the position of the extrusion plate 22 is fixed, which is convenient for the reuse of the lubrication structure 1. When the rotating part is lubricated, the electromagnet three 19 and the electromagnet four 11 are energized. The repulsive force when the electromagnet three 19 and the electromagnet four 11 are energized can be used to make the oil squeeze ring 20 squeeze out the lubricating oil in the oil storage ring 16, and the squeezed lubricating oil is sprayed on the rotating part to facilitate the operation of the component.
