A sliding guide plate 12 is arranged on the outer surface of the ball screw 11. The feeding device 2 includes a fixed frame 201. A second motor 202 is fixedly connected to the outer surface of the fixed frame 201. The output shaft of the second motor 202 is fixedly connected to a driving roller 203. A driven roller 204 is rotatably connected to the outer surface of the fixed frame 201. A conveyor belt 205 is arranged on the outer surfaces of the driving roller 203 and the driven roller 204. A feeding housing 206 is fixedly connected to the outer surface of the conveyor belt 205. A third motor 207 is fixedly connected to the outer surface of the feeding housing 206. The output end of the third motor 207 is fixedly connected to a rotating shaft 208. A stirring plate 209 is fixedly connected to the outer surface of the rotating shaft 208.

[0022] Specifically, a buffer spring 6 is sleeved on the outer surface of the movable rod 5. The end of the buffer spring 6 is fixedly connected to the top of the support column 4. The end of the buffer spring 6 far from the support column 4 is fixedly connected to the lower surface of the sand screening plate 7.

[0023] Specifically, the outer surface of the sand sifting plate 7 penetrates through the impurity outlet 9 and extends to the outside. One end of the ball screw 11 away from the first motor 10 is rotatably connected to the inner surface of the sand sifting housing 1. The sliding guide plate 12 is arranged above the sand sifting plate 7.

[0024] Specifically, the fixing frames 201 are symmetrically arranged on both sides of the driving roller 203 and the driven roller 204. The driving roller 203 is arranged directly below the driven roller 204.

[0025] Specifically, the feeding sleeves 206 are linearly arranged along the outer surface of the conveyor belt 205.

[0026] Specifically, the outer surface of the rotating shaft 208 penetrates through the feeding sleeve 206 and extends into the inner cavity. One end of the rotating shaft 208 away from the third motor 207 is rotatably connected to the inner surface of the feeding sleeve 206.

[0027] The working principle and beneficial effects of the above embodiments.

[0028] During use, the sand is poured into the feeding sleeve 206 in batches. The second motor 202 is started to drive the driving roller 203 to rotate. With the cooperation of the driven roller 204, the conveyor belt 205 is driven to rotate clockwise. The feeding sleeve 206 moves accordingly. At the same time, the third motor 207 is started, so that the rotating shaft 208 drives the stirring plate 209 to rotate, and the spiral stirring plate 209 stirs the sand, so that some of the sand agglomerated due to moisture is dispersed, improving the subsequent sand sifting efficiency. When the feeding sleeve 206 moves to the top of the conveyor belt 205, the first motor 10 is started to drive the ball screw 11 to rotate, so that the sliding guide plate 12 moves to the alignment position with the feeding sleeve 206, and the sand in the feeding sleeve 206 is guided into the sand sifting housing 1 along the sliding guide plate 12. After the sand in the feeding sleeve 206 is emptied, the first motor 10 is started again to make the sliding guide plate 12 move horizontally until it leaves directly below the feeding sleeve 206, so that the conveyor belt 205 continues to drive and conveys the next feeding sleeve 206 to the top of the conveyor belt 205. By repeating the above operations, automatic feeding of the sand is realized, saving manpower. The sand entering the sand sifting housing 1 falls on the sand sifting plate 7. The vibrator 8 drives the sand sifting plate 7 to vibrate at a high frequency, so that the sand passes through the through holes on the sand sifting plate 7 and is discharged from the blanking port 3. The impurities in the sand slide out from the impurity outlet 9 along the sand sifting plate 7.
