An annular groove 22 is provided around the top of the support ring 7. A motor 4 is fixed at the center of the bottom of the bottom of the bottom box 3, the intermediate box 8 and the top box 9. A swivel box 6 is movably connected at the center of the lower part of the bottom box 3, the intermediate box 8 and the top box 9. A filter screen 21 is fixed at the bottom of the swivel box 6. A slot 20 is provided at the bottom of the bottom box 3, the intermediate box 8 and the top box 9. A ball bearing 18 is movably embedded at the bottom of the swivel box 6. A diversion plate 19 is provided at the lower part of the bottom box 3, the intermediate box 8 and the top box 9.

[0023] The top of the output end of motor 4 is fixedly connected to the sling box 6, the bottom of the ball bearing 18 is embedded in the annular groove 22, and the side of the bottom of the sling box 6 rotates along the support ring 7.

[0024] Specifically, such as Figure 1and Figure 2 As shown, cement powder is first poured into the top box 9's sluice box 6. After starting the motor 4, the sluice box 6 is rotated. The sluice box 6 with ball bearings 18 rotates along the annular groove 22 at the top of the support ring 7. Large particles of debris are intercepted through the coarse-pore filter screen 21. The remaining material flows through the trough 20 into the sluice box 6 in the middle box 8. The material is then screened again through a smaller filter screen 21. Finally, it is screened by the finest filter screen 21 in the bottom box 3. This process enables multiple screening of concrete mortar.

[0025] A flexible hose 25 is fixed to the bottom of the slot 20, and a collar 5 is fixed to the bottom of the flexible hose 25. Cylinders 24 are installed on both sides of the top of the collar 5. Motor 3 23 is fixed to the side of the bottom of the bottom box 3, the middle box 8 and the top box 9. A limit plate 17 is fixed to the bottom of the output end of the motor 3 23. The motor 3 23 guides the limit plate 17 to rotate horizontally. The top of the cylinder 24 is fixedly connected to the bottom box 3, the middle box 8 and the top box 9 respectively. The piston rod of the cylinder 24 guides the collar 5 to rise and fall vertically.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, when one of the boxes in the bottom box 3, the middle box 8 and the top box 9 is performing a screening operation, the internal mechanism of the box below it is in a stopped state, which facilitates the symmetrical cylinder 24 to settle the collar 5 and extend the hose 25 until the collar 5 below is embedded in the corresponding throwing box 6 for material transfer, thereby realizing the automated processing of screening and discharge.

[0027] A vertical rod 16 is fixed to the left side of the top of the base 1, and a worm gear 13 is movably connected to the top of the vertical rod 16. A rotating rod 12 is fixed to the top of the worm gear 13. A motor 11 is fixed to the right side inside the rotating rod 12. A material box 10 is movably connected to the right side of the rotating rod 12. A bracket 15 is fixed to the top of the left side of the vertical rod 16, and a motor 26 is fixed to the top of the front end of the bracket 15. A worm gear 14 is movably connected between the front and rear of the bracket 15. The output end of the motor 26 is fixedly connected to the worm gear 14 at the rear. The output end of the motor 11 is connected to the material box 10 at the right side.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, the worm gear 14 in the bracket 15 is rotated by the motor 26, thereby horizontally rotating the rotating rod 12 above the vertical rod 16 to adjust the left and right positions of the material box 10. After the material box 10 receives the material on the left side, it is rotated to the right side and self-locked. The material box 10 is longitudinally rotated by the motor 2 11 on the side of the rotating rod 12, and the unscreened cement powder is poured into the top box 9 and the throwing box 6.

[0029] Working Principle: In use, the worm gear 14 in the support bracket 15 is first rotated by motor 426, thereby horizontally rotating the rotating rod 12 above the vertical rod 16 to adjust the left and right positions of the material box 10. After the material box 10 is on the left side receiving material, it is rotated to the right side and self-locked. Motor 21 then vertically rotates the material box 10 along the side of the rotating rod 12, pouring unscreened cement powder into the top box 9's throwing box 6. Motor 4 is then started, rotating the throwing box 6. The throwing box 6, equipped with ball bearings 18, rotates along the annular groove 22 at the top of the support ring 7, passing through the coarse holes. Filter screen 21 traps large particles of debris, while the remaining material flows through the trough 20 into the sluice box 6 in the intermediate box 8. It then passes through a smaller filter screen 21 for further screening, and finally is screened by the finest filter screen 21 in the bottom box 3. This allows for multiple screening processes of concrete mortar. When one of the boxes in the bottom box 3, intermediate box 8, or top box 9 is performing a screening operation, the internal mechanisms of the box below it are all stopped, allowing the symmetrical cylinders 24 to lower the collar 5 and extend the flexible hose 25 until the collar 5 is embedded in the corresponding sluice box 6 for material transfer.
