[0042] The working process of this utility model:

[0043] In use, the casting is first hoisted using the lifting hook 305. Then, the second motor 303 is started, which drives the support rod 304 to rotate. The rotation of the support rod 304 moves the lifting hook 305, sending the casting into the cleaning box 1. The height of the lifting hook 305 can be adjusted by adjusting the lifting platform 301 to align the casting with the shot blasting machine 4. During the cleaning process of the shot blasting machine 4, the adjusting motor 306 can be started. The adjusting motor 306 drives the first bevel gear 307 to rotate, which in turn drives the second bevel gear 308 to rotate. The rotation of the second bevel gear 308 drives the lifting hook 305 to rotate, which in turn rotates the suspended casting, making the cleaning of the casting by the shot blasting machine 4 more uniform. During the cleaning process, any casting parts that fall off are removed. The foundry sand and shot fall into the funnel hopper 11, which allows them to smoothly enter the sieve basket 202. After the first motor 205 starts, it drives the turntable 204 to rotate. When the turntable 204 rotates, it drives the left end of the connecting rod 203 to make a circular motion around the center of the turntable 204. The right end of the connecting rod 203 is rotatably connected to the left end of the sieve basket 202, thereby driving the sieve basket 202 to move back and forth, thus screening the foundry sand and shot in the sieve basket 202. The foundry sand will be screened out of the sieve basket 202 and fall into the sand receiving hopper 206. The screened shot will be transported from the shot outlet 10 opened at the right end of the sieve basket 202 to the shot collection box 5. The spiral elevator 6 then transfers the shot in the shot collection box 5 to the shot blasting machine 4, forming a cycle.

[0044] 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
