After the processing is completed, the right end of the electric-controlled unloading mechanism 4 is flipped downward, and the unloading port on the other side of the reaction bin 2 is opened at the same time, and then the electric-controlled material-discharging mechanism 5 is rotated to introduce the processed fasteners into the electric-controlled unloading mechanism 4, and then the unloading operation is completed; at the same time, the next batch of materials is lifted upward by the electric-controlled feeding mechanism 3, and when the material inside the reaction bin 2 is completely discharged, the next batch of materials begins to be introduced, thereby achieving the purpose of seamless connection.

[0030] In order to cooperate with the electric-controlled flip opening and closing control, arc-shaped material delivery ports 7 are opened on both side walls of the reaction bin 2, and an electric-controlled flip closing cover plate is movably installed inside the arc-shaped material delivery port 7.

[0031] In order to facilitate height adjustment and improve guidance, a strip-shaped guide opening 7 is provided on the longitudinal back plate of the reaction chamber 2 .

[0032] In order to cooperate with the electric control lifting and adjustment, the electric control lifting centrifugal shot blasting mechanism 6 includes an internal slider 61 slidably installed inside the strip guide port 7, an electric control elevator 62 fixed on the back of the reaction chamber 2, lateral sealing plates 63 fixed on both sides of the internal slider 61, a horizontal material guide barrel 64 fixed inside the internal slider 61, a centrifugal shot blasting cover 65 axially installed on the inner end of the horizontal material guide barrel 64, a centrifugal shot blasting blade 66 installed inside the centrifugal shot blasting cover 65 and a bottom material return mechanism 67 coordinated with the horizontal material guide barrel 64.

The processed waste is hammered into the shot blasting separation box 674 through the filter screen on the curved pipe inside the shot blasting separation box 674, and the shot blasting remaining in the curved pipe is returned upward to the interior of the horizontal guide cylinder 64 along the shot blasting guide pipe 675.
