Description
Technical Field
[0001] The utility model relates to the technical field related to shot blasting machines, in particular to a box-type shot blasting machine which is convenient for discharging and collecting materials. Background Art
[0002] When the surface of various metal and non-metal workpieces is cleaned and strengthened by a box-type shot blasting machine, the projectiles used for processing will be mixed with impurities such as debris on the surface of the workpiece and fall to the bottom of the inner cavity of the shot blasting machine. This requires that when the projectiles are discharged and recovered after the shot blasting process is completed, the debris mixed in the projectiles needs to be removed. Most of the existing shot blasting machines still use a more traditional rotary screen plate to separate the projectiles and debris. However, this more traditional rotary screen plate structure mainly rotates in one direction, which results in a relatively single movement direction of the projectiles and debris on the upper side of the screen plate, which obviously limits the separation effect of the projectiles and debris. For this reason, we propose a box-type shot blasting machine that is easy to discharge and collect. Utility Model Content

A fan 122 is provided to guide the air, so as to facilitate pushing impurities such as debris inside the pellet recovery chamber 11 into the exhaust chamber 121.
[0028] The upper side of the projectile recovery chamber 11 is arranged in a funnel shape, and the screening plate 111 is arranged in a cone shape. When the screening plate 111 moves upward to separate from the upper side of the projectile recovery chamber 11, the projectile can enter the projectile recovery chamber 11 from the gap between the two;

[0031] Specifically, an electric push rod 3 is provided to drive the screening plate 111 to move up and down, so that the screening plate 111 is separated from or closed by the projectile recovery chamber 11, and through the plug-in cooperation between the driving gear rod 33 and the movable gear sleeve 34, after the screening plate 111 moves upward, the reduction motor 14 can still drive the screening plate 111 to reciprocate through its output shaft, ensuring that the screening plate 111 can centrifugally throw out the projectiles at its upper end, thereby improving the discharge effect of the projectiles.
[0032] Working principle: When in use, the workpiece to be processed can be guided into the box 1 through the conveyor mesh belt 10, and the workpiece can be shot blasted with the projectiles sprayed from the inner wall of the box 1, and the projectiles sprayed by the device will mix with the debris falling off the surface of the workpiece and fall to the upper end of the screening plate 111;

[0035] When the projectiles are to be recovered, the electric push rod 3 is started, and the electric push rod 3 drives the movable plate 32 and the movable rod 15 in the middle of the movable plate 32 to move upward through its output shaft, so that the screening plate 111 moves upward until it is separated from the upper side of the projectile recovery chamber 11, so that a gap is formed between the two, so that the projectiles at the upper end of the screening plate 111 can enter the projectile recovery chamber 11 from the gap between the two, and the projectile guide plate 13 and the projectile guide chamber 131 can be used to collect and discharge the projectiles. After the movable rod 15 is lifted, the driving gear rod 33 and the movable gear sleeve 34 are always plugged into each other. At this time, the reduction motor 14 is started, and the output shaft of the reduction motor 14 can still drive the screening plate 111 to be lifted upward for rotation, so that the screening plate 111 can throw the projectiles at its upper end outward, thereby ensuring the projectile discharge and collection effect of the device.
