[0002] Ore refers to valuable mineral stones mined from mines. After being processed through multiple processes, the mined ore can be used in various engineering fields. After mining, the ore needs to be transported by an ore conveyor. Currently, the more common ore conveyor devices on the market are belt conveyors. Due to the heavy weight of the ore, in order to maintain the stability of the belt conveyor operation, support rollers are generally provided at the bottom of the upper conveyor belt to provide auxiliary support for the upper conveyor belt.

[0003] The support roller is generally directly installed on the bearing seat through the bearing. During the operation of the bearing, friction will be generated between the rolling surfaces of the bearing, resulting in rapid wear of the bearing. In the prior art, the bearing is generally lubricated by manually adding lubricating oil into the bearing, which increases the labor intensity. In addition, the continuously rotating support roller will hinder the staff from adding lubricating oil and endanger the safety of the staff. Therefore, the conveying device needs to be shut down before the lubricating oil can be added, which reduces the conveying efficiency of the ore. Summary of the invention

[0039] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 2. This embodiment is intended to solve the problem of poor drainage effect of the oil storage chamber 801. For details, please refer to Figure 1 , Figure 4 and Figure 8A valve core 57 is slidably connected to the inside of the second oil inlet pipe 56. The second oil inlet pipe 56 and the valve core 57 are both cylindrical in shape with one end open and the other end blocked.

In the process of the telescopic drive assembly driving the second oil outlet pipe 13 to move in the direction of the second oil inlet pipe 56, when the end of the second oil outlet pipe 13 contacts the valve core 57 and continues to move, the valve core 57 will be pushed into the first oil inlet pipe 17 until the connecting hole 58 moves to the position of the first oil inlet pipe 17 and is connected to the first oil inlet pipe 17. 17 is connected, and the third spring 60 is compressed at this time, so that the oil pump can work, and the lubricating oil in the oil tank 11 is pumped to the valve core 57 through the first oil outlet pipe 12 and the second oil outlet pipe 13, and then enters the first oil inlet pipe 17 from the connecting hole 58, and then enters the oil bag 15. When the oil bag 15 is filled with oil, the telescopic drive component drives the second oil outlet pipe 13 to be retracted and reset from the second oil inlet pipe 56, so that the third spring 60 loses pressure and resets, thereby driving the valve core 57 to move outward and reset, and continue to block the first oil inlet pipe 17 to ensure the sealing effect of the oil bag 15; When the valve core 57 moves inward, the piston 59 at the end of the valve core 57 pressurizes the air inside the second oil inlet pipe 56, thereby inflating the oil storage chamber 801 through the air outlet pipe 61, thereby improving the sewage discharge effect of the oil storage chamber 801.

[0041] Embodiment 4: This embodiment is an improvement made on the basis of Embodiment 3. This embodiment is intended to promote the solution of the problem that the second oil inlet pipe 56 is open and dust easily enters the second oil inlet pipe 56. For details, please refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 The lubricating oil transfer mechanism also includes a dustproof plate 46, which is arranged on the front side of the second oil inlet pipe 56, a transmission block 47 is fixedly provided at the lower end of the dustproof plate 46, a guide rail 48 for slidingly connecting the transmission block 47 is fixedly provided on the side wall of the first protective shell 14, and a fixed block 49 is fixedly provided on the side wall of the first protective shell 14, and a second spring 50 is connected between the fixed block 49 and the transmission block 47.

[0042] A first connecting block 51 is fixed to the side wall of the oil tank 11, a fourth rotating shaft 52 is fixed to the upper end of the first connecting block 51, a second connecting block 53 is rotatably provided on the upper end of the outer surface of the fourth rotating shaft 52, a torsion spring 54 is connected between the second connecting block 53 and the first connecting block 51, and a push rod 55 is fixed to the end of the second connecting block 53 away from the oil tank 11.

[0043] More specifically, in this embodiment: in the initial state, the dustproof plate 46 is located in front of the second oil inlet pipe 56, blocking the second oil inlet pipe 56, so that external dust does not enter the second oil inlet pipe 56, thereby further improving the sealing effect of the oil bag 15, and further preventing the lubricating oil with dust from contacting the bearing 7 and aggravating the wear of the bearing 7; When it is necessary to inject oil into the oil bag 15 at this location, when the oil tank 11 of the oil delivery mechanism moves toward the second oil inlet pipe 56, the push rod 55 first moves with the oil tank 11. When the push rod 55 moves to contact with the transmission block 47, the push rod 55 continues to move, and the push rod 55 will push the transmission block 47 to move, thereby driving the dustproof plate 46 to move, so that the dustproof plate 46 is away from the second oil inlet pipe 56, so that the opening of the second oil inlet pipe 56 is exposed and unobstructed. At this time, the second spring 50 is gradually compressed. When the opening of the second oil inlet pipe 56 is unobstructed, it will not hinder the second oil inlet pipe 56 from docking with the second oil outlet pipe 13. When the oil at this location After the bag 15 is filled with oil, when the oil tank 11 of the oil delivery mechanism continues to move to the next position, since the second spring 50 is compressed to the shortest, the transmission block 47 can no longer move. At this time, the transmission block 47 will form an extrusion force on the push rod 55, causing the push rod 55 to rotate and the torsion spring 54 to twist, so that the push rod 55 will not hinder the movement of the oil tank 11. When the push rod 55 moves to disengage from the transmission block 47, the torsion spring 54 resets and drives the push rod 55 to reset, and at the same time makes the transmission block 47 lose its restriction. The second spring 50 resets and drives the transmission block 47 to reset, thereby driving the dustproof plate 46 to automatically reset, and continue to block the oil inlet pipe 17.
