In another embodiment, the sleeve ring 41 can be omitted, and the spring directly abuts against the outer wall of the second column 122. In another embodiment, the V-shaped spring sheet can be replaced by the driving spring 42.

[0033] In combination Figure 1 With reference to Figure 4 With Figure 5 In more detail, the outer wall of the sleeve ring 41 is welded with spring columns, and the number of the spring columns is the same as and corresponds to the number of the driving springs 42.

The cam driving assembly 5 is arranged on the supporting long plate 16, and the cam driving assembly 5 is connected with the rotating column 131. When the rotating column 131 rotates, the cam driving assembly 5 will rotate synchronously with the rotating column 131, and the cam driving assembly 5 can drive the hopper 3 to shake at a high frequency.

[0035] Specifically, the cam driving assembly 5 comprises a driving pulley 51, a driven pulley 52, a synchronous belt 53 and a driving cam 54. The driving pulley 51 is sleeved on the rotating column 131 and rotates synchronously with the rotating column 131. The driven pulley 52 is rotatably arranged on the supporting long plate 16, the synchronous belt 53 is sleeved on the driving pulley 51 and the driven pulley 52, and is adapted to drive the driving pulley 51 to drive the driven pulley 52 to rotate synchronously. The driven pulley 52 is welded with a sleeve pipe 55 at one end away from the supporting long plate 16, and the driving cam 54 is welded at one end of the sleeve pipe 55 away from the driven pulley 52. The driving cam 54 can be located at the middle position outside the hopper 3 through the sleeve pipe 55, and the driving cam 54 is adapted to contact the hopper 3 to drive the hopper 3 to vibrate from the middle position of the hopper 3, thereby improving the vibration effect.

[0036] Referring to Figure 4 With Figure 5 Wherein, the outer wall of the hopper 3 is welded with a reinforcing plate 33, the driving cam 54 is attached to the side of the reinforcing plate 33 away from the hopper 3, and the outer wall of the driving cam 54 is integrally formed with a protrusion, so that when the protrusion rotates to the reinforcing plate 33, a pushing force is applied to the hopper 3 to drive the hopper 3 to move, and when the protrusion is not located at the reinforcing plate 33, the hopper 3 is reset under the action of the driving spring 42, so that the hopper 3 forms vibration. The arrangement of the reinforcing plate 33 can increase the strength of the contact between the hopper 3 and the driving cam 54, and improve the service life of the hopper 3.

[0037] The implementation principle of the steel wheel type wear resistance test device according to an embodiment of the present application is as follows: when the driving motor 11 drives the grinding steel wheel 2 to rotate to rub the measured object, the driving cam 54 also starts to rotate, and when the protrusion rotates to the reinforcing plate 33, a pushing force is applied to the hopper 3 to drive the hopper 3 to move, and when the protrusion is not located at the reinforcing plate 33, the hopper 3 is reset under the action of the driving spring 42, and with the high-speed rotation of the grinding steel wheel 2, the driving cam 54 drives the hopper 3 to form high-frequency vibration, so that the abrasive is not easy to be caked after the hopper 3 vibrates, and the caked abrasive can be scattered, so that the abrasive is uniformly discharged.
