[0020] 1. The shot-residue separation device for the shot blasting machine is provided with a separation component. When the first rotating shaft rotates, the second rotating shaft is driven to rotate. When the second rotating shaft rotates, the first tooth pattern at the bottom of the second rotating shaft drives the gear between the second rotating shaft and the first connecting rotating shaft to rotate. When the gear rotates, the first connecting rotating shaft is driven to rotate. When the first connecting rotating shaft rotates, the second tooth pattern at the bottom of the first connecting rotating shaft drives the gear between the first connecting rotating shaft and the third rotating shaft to rotate. When the gear rotates, the stirring shaft is driven to rotate. When the stirring shaft rotates, the first connecting rod is driven to rotate. When the first connecting rod rotates, the first connecting rod rotates. When it moves, it will drive the billiard ball to rotate. When the first connecting rod and the billiard ball rotate, they will hit and vibrate the projectiles, thereby separating the slag attached to the projectiles. When the gears between the second rotating shaft and the first connecting rotating shaft rotate, the gears on both sides of the third connecting rotating shaft rotate in different directions, and the stirring shafts on both sides of the outer spacer ring of the second rotating shaft also turn in different directions. Similarly, when the gears between the first connecting rotating shaft and the third rotating shaft rotate, the stirring shafts on both sides of the outer spacer ring of the third rotating shaft also turn in different directions, which will fully and completely vibrate the projectiles in the main bin, thereby fully separating the projectiles from the slag.

When the first rotating shaft rotates, it will drive the fan blades to rotate. When the fan blades rotate, the airflow on one side of the fence will be brought into the main bin through the partition. The separated slag will fall down onto the screen plate with the airflow, thereby promoting the separation of the shot-residue.

[0022] 3. The shot-residue separation device for the shot blasting machine is equipped with a sub-screening component. The slag falling onto the screen plate will fall into the bottom bin through the screen holes. When the third shaft rotates, the stirring plate at the bottom of the third shaft will be driven to rotate.

When the gear between the second rotating shaft and the first connecting rotating shaft rotates, the gears on both sides of the third connecting rotating shaft rotate in different directions, and the stirring shafts on both sides of the outer spacer ring of the second rotating shaft also turn in different directions. Similarly, when the gear between the first connecting rotating shaft and the third rotating shaft rotates, the stirring shafts on both sides of the outer spacer ring of the third rotating shaft also turn in different directions. The projectiles in the main bin will be fully vibrated, thereby fully separating the projectiles from the slag.

[0026] 7. The shot-residue separation device for the shot blasting machine is provided with a first connecting shaft and a second connecting shaft. When the gear contacts and rotates with the first connecting shaft, the gear will rotate around the second connecting shaft, so that the gear will drive the third connecting shaft to rotate around the second connecting shaft, and the third connecting shaft will drive the second connecting shaft to rotate. When the second connecting shaft rotates, the first limit blocks at both ends of the second connecting shaft will rotate in the connecting groove and the stirring shaft to maintain internal stability.

When the stirring plate 317 rotates, the slag will be sent to the sieve hole 402, so that the slag can be fully screened. Since the stirring plate 317 is an inclined straight plate, it will prevent the slag from accumulating on the stirring plate 317, and it is convenient to screen the slag. When the separation component 300 vibrates the shot, the shot will collide with the sieve plate 401, thereby promoting the slag to be screened. When the sieve plate 401 is hit, the vibration will be transmitted to the movable plate 403 outside the sieve plate 401. The movable plate 40 3 will drive the sieve plate 401 to move downward, at this time, the movable plate 403 will move in the first movable groove 109, the downward movement of the movable plate 403 will compress the spring 407, and the spring 407 will provide a reaction force to move the second connecting rod 404 along the second connecting rod 404 and restore, the second limit block 405 will limit the movable plate 403, this process will absorb the excessive impact kinetic energy of the sieve plate 401, when the sieve plate 401 is continuously vibrated, the movable plates 403 around the sieve plate 401 will be adjusted to prevent the sieve plate 401 from being deformed, thereby extending the service life of the sieve plate 401 and maintaining the sieve plate 401 for normal use.

[0054] After waiting for the separation of the pellets and residue to be completed, you can pull the second lifting rod 113 to move the second lifting rod 113 upward, and the second lifting rod 113 will drive the second moving rod 112 to move upward, and the two ends of the second moving rod 112 will move between the second limiting rod 114 and the main bin 101. When the second moving rod 112 moves, it will drive the discharge door panel 111 to move upward, and the separated pellets can be poured out from the discharge bucket 110.
