[0002] Shot blasting machine is a kind of equipment that cleans the floating slurry and other dirt on the outer surface of the workpiece by impacting and rubbing the outer surface of the workpiece with a large number of small-size steel shots. The metal steel shots in the shot blasting machine not only clean the surface of the workpiece, but also make the surface of the workpiece obtain a certain degree of roughness. After the steel shots in the shot blasting machine have impacted the outer surface of the workpiece, they will be discharged from the shot blasting machine together with the workpiece, recovered and put into use again.
[0003] However, after repeated use, each steel shot will produce different degrees of wear, resulting in different particle sizes of steel shots. Steel shots of different particle sizes will affect the cleaning effect of the shot blasting machine when used. Therefore, a steel shot screening device for a shot blasting machine is designed.

DETAILED DESCRIPTION
[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a steel shot screening device for a shot blasting machine includes a frame 1, a screen body slidably connected to the frame 1, a screening motor 3 fixed to the frame 1, and a transmission assembly used to connect the screening motor 3 and the screen body; the screen body includes an inclined U-shaped bottom plate 21, a screen plate 22 fixed in the U-shaped bottom plate 21, the lateral part of the U-shaped bottom plate 21 is arranged opposite to the screen plate 22, the bottom end of the U-shaped bottom plate 21 is inclined backward and the bottom end of the U-shaped bottom plate 21 is provided with a fine particle outlet 211, the bottom end of the screen plate 22 is provided with a coarse particle outlet 221, and the screening motor 3 drives the U-shaped bottom plate 21 to screen left and right through the transmission assembly.
[0019] When in use, the steel shots to be screened are poured onto the sieve plate 22 near the top of the U-shaped bottom plate 21. During the process of the steel shots rolling down along the sieve plate 22, the screening motor 3 drives the U-shaped bottom plate 21 to screen left and right through the transmission assembly, so that the steel shots with too small particle size on the sieve plate 22 pass through the sieve holes on the sieve plate 22 and fall into the U-shaped bottom plate 21, and the large-particle steel shots are discharged from the coarse-particle outlet 221 along the sieve plate 22, and the steel shots with too small particle size are discharged from the fine-particle outlet 211 along the transverse part of the U-shaped bottom plate 21. The utility model can select the steel shots with too small particle size, so that the steel shots with particle size that meet the standard can be reused, thereby ensuring the cleaning effect of the shot blasting machine.
[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the output end of the screening motor 3 is driven and connected with a driving gear 31, a slide bar 11 is arranged on the frame 1, a slide seat 23 is arranged at the bottom end of the U-shaped bottom plate 21, and the slide seat 23 is slidably connected to the slide bar 11; the transmission assembly includes a screening roller 41 rotatably connected to the frame 1, a driven gear 42 is arranged at one end close to the screening roller 41, the driving gear 31 and the driven gear 42 are connected by a transmission belt 43, and an annular guide groove 411 is arranged on the screening roller 41, and two opposite ends of the annular guide groove 411 are respectively centered on the axis of the screening roller 41 toward the screening roller 41 The annular guide groove 411 extends at both ends, and a slider is slidably connected in the annular guide groove 411. After one end of the slider extends out of the annular guide groove 411, it is fixedly connected to the slide seat 23. In this embodiment, the screening motor 3 drives the screening roller 41 to rotate through the driving gear 31, the transmission belt 43 and the driven gear 42. During the rotation of the screening roller 41, the slider slides along the annular guide groove 411. Since the two opposite ends of the annular guide groove 411 extend toward the two ends of the screening roller 41 with the axis of the screening roller 41 as the center, the slider drives the slide seat 23 to slide left and right along the slide rod 11 during the sliding process, thereby driving the U-shaped bottom plate 21 on the slide seat 23 to screen left and right.
[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the number of teeth of the driving gear 31 is less than that of the driven gear 42; in this embodiment, when the number of teeth of the driving gear 31 is less than that of the driven gear 42, the driving gear 31 and the driven gear 42 connected by the transmission belt 43 can further reduce the rotation speed of the motor, thereby achieving a better screening effect.
[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, shock-absorbing pads 24 are respectively arranged on the opposite surfaces of the vertical portion of the U-shaped bottom plate 21; in this embodiment, by respectively arranging shock-absorbing pads 24 on the opposite surfaces of the vertical portion of the U-shaped bottom plate 21, the sound of the steel shot screen hitting the U-shaped bottom plate 21 can be effectively reduced, and the practicality is better.
[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the fine particle outlet 211 and the coarse particle outlet 221 are staggered. In this embodiment, when the fine particle outlet 211 and the coarse particle outlet 221 are staggered, it is more convenient to collect the materials after screening.
[0024] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the scope defined by the spirit of the present invention.
