[0025] Embodiment 1: By arranging a buffer box 3, a push plate 4, a damper 5, a ramp block 6, a tension spring 7, a lower pressure plate 8, an automatic refueling assembly 9, an oil storage tank 901, a motor 902, a threaded sleeve 904, a push rod 905, a piston 906 and an oil hose 907, the impact force generated when the material falls when the hopper is fed can be transmitted and absorbed by the damper 5, thereby improving the buffering effect of the roller body 2 and increasing its service life.

[0026] In one possible implementation, see Figure 1-5, a long-life belt conveyor roller, the front and rear sides of the inner cavity of the frame 1 are fixedly connected with positioning guide rails 10, the surface of the positioning guide rails 10 is slidably connected with a positioning block 11, the positioning block 11 is fixedly connected to the roller body 2 on the side away from the positioning guide rail 10, the top between the front and rear sides of the inner cavity of the buffer box 3 is fixedly connected with a sliding rod 12, the front and rear sides of the surface of the sliding rod 12 are slidably connected with a sliding sleeve 13, the bottom of the sliding sleeve 13 is fixedly connected to the push plate 4, and movable openings for use with the lower pressure plate 8 are opened on both sides of the frame 1, and the front and rear sides of the lower pressure plate 8 are fixedly connected with cylindrical pressure blocks.

[0027] Embodiment 2: By setting a positioning guide rail 10, it can cooperate with the positioning block 11 to limit the roller body 2 so that it can only move up and down. By setting a slide rod 12 and a sliding sleeve 13, the push plate 4 can be limited so that it can move forward and backward smoothly. By setting a movable opening, the lower pressure plate 8 can be conveniently transmitted to the inclined block 6. By setting a cylindrical pressure block, the inclined surface of the inclined block 6 can be squeezed so that it transmits the impact force to the push plate 4 and the damper 5.

[0028] On the basis of Example 1, this embodiment describes the automatic refueling component 9 in Example 1. The automatic refueling component 9 includes an oil storage tank 901, and the front side of the oil storage tank 901 is fixedly connected to the motor 902. The rear side of the output end of the motor 902 passes through the oil storage tank 901 and is fixedly connected to a screw 903. The surface of the screw 903 is threadedly connected to a threaded sleeve 904. The top and bottom of the threaded sleeve 904 are fixedly connected to a push rod 905. A piston 906 is provided on the rear side of the screw 903. The rear side of the piston 906 is fixedly connected to the push rod 905. The rear side of the oil storage tank 901 is connected to an oil delivery hose 907. The end of the oil delivery hose 907 away from the oil storage tank 901 is fixedly connected to the bearing of the roller body 2. The rear side of the top of the oil storage tank 901 is connected to an oil filling pipe. The top of the oil filling pipe is threadedly connected to a sealing cover. The rear side of the screw 903 is fixedly connected to a block. The front sides of the top and bottom of the inner cavity of the oil storage tank 901 are fixedly connected to slide rails, and the surfaces of the slide rails are slidably connected to sliders. The opposite sides of the two sliders are fixedly connected to the push rod 905. The motor 902 is turned on at a regular time, and the motor 902 cooperates with the screw 903 to drive the threaded sleeve 904 and the push rod 905 to move. The push rod 905 controls the movement of the piston 906. The piston 906 transports the lubricating oil stored in the oil storage tank 901 to the bearings of the roller body 2 through the oil hose 907, so that it can be continuously lubricated, avoiding wear and tear during long-term work, and further improving its service life. By setting an oil filling pipe, the lubricating oil can be easily injected into the oil storage tank 901, and by setting a block, the threaded sleeve 904 can be prevented from separating from the surface of the screw 903. By setting a slide rail and a slider, the threaded sleeve 904 can be prevented from rotating, and it can move back and forth smoothly.

[0029] Working principle: When the hopper throws the material onto the top of the conveyor belt, the roller body 2 drives the lower pressure plate 8 to move downward, and the lower pressure plate 8 moves to squeeze the two inclined blocks 6. After the inclined surfaces of the two inclined blocks 6 are squeezed, they drive the push plate 4 to stretch the tension spring 7, and the tension spring 7 absorbs part of the impact force. At the same time, the push plate 4 squeezes the damper 5, and the damper 5 absorbs the remaining impact force. Since the roller body 2 is not rigidly fixed, the above-mentioned components can absorb the impact force when the roller body 2 is impacted, thereby avoiding damage caused by the impact force for a long time and increasing its service life. During the operation of the roller body 2, the motor 902 is turned on at regular intervals, and the motor 902 cooperates with the screw 903 to drive the threaded sleeve 904 and the push rod 905 to move. The push rod 905 moves to drive the piston 906 to discharge the lubricating oil inside the oil tank 901 to the oil hose 907, and the lubricating oil is transported to the bearings of the roller body 2 through the oil hose 907, so that it can be lubricated regularly, thereby avoiding wear caused by long-term work and further increasing its service life.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
