[0002] In the processing of steel members, it is necessary to first perform shot peening on the oxide layer and rust of the steel members before spraying. Shot peening cleaning uses the high-pressure gas in the shot peening nozzle to mix with the shot peening particles to generate an impact force, and blows the shot peening particles onto the surface of the steel to be processed at a very high ray speed, generating a striking and grinding effect to remove the oxide layer and rust on the surface of the steel. Therefore, in the production process of shot peening particles, it is necessary to screen them to remove impurities or defective products contained in the materials.

[0003] When the traditional screening machine is in use, first start the screening machine, then pour the shot peening particle material onto the screen above the surface of the screening machine, and then screen the shot peening particles during the vibration operation of the screening machine, and then output the qualified products and the impurities and defective products from different discharge pipes, so as to complete the screening of the shot peening particles. However, it is found in the actual use process that when pouring the shot peening particle material onto the screen, it is difficult for the staff to control the amount of the material poured, which is easy to cause the accumulation of the material, thus increasing the burden on the screening machine and affecting the working efficiency and use effect of the screening machine.

When using the screening machine 1 to screen the shot peening particles, first use the fixing device 5 to install the feeding device 4 on the surface of the screening machine 1, then pour the shot peening particles into the feeding device 4, then start the screening machine 1 to make it operate, then make the falling amount and rate of the shot peening more stable through the feeding device 4, then perform screening on the screen 3, and finally remove the qualified products and defective product impurities from different discharge pipes 2. At this time, the screening machine 1 can screen the shot peening particles more efficiently, and it is not easy to have the occurrence of particle accumulation, which affects the normal use of the screening machine 1 and increases the operating burden of the screening machine 1, improving the use effect and working efficiency of the screening machine 1.

[0029] Referring to Figure 1 and Figure 2 and Figure 3As shown in the figure, in this embodiment, the hopper 41 is installed on the surface of the screening machine 1 by means of a fixing device 5.
