[0027] A rapid concrete feeding device includes a feeding box 1. A first funnel is provided on the top of the feeding box 1. A first protective box is provided on the right side of the feeding box 1. A first motor 18 is provided inside the first protective box. A first crushing roller 19 is provided at the output end of the first motor 18. A first gear 24 is provided on the outer surface of the first crushing roller 19 near the output end of the first motor 18. A second protective box is provided at the rear of the feeding box 1. A second motor 27 is provided inside the first protective box. A turntable 28 is provided at the output end of the second motor 27. A lever 30 is provided on one side of the turntable 28. A second crushing roller 25 is rotatably connected to the inside of the feeding box 1 through a bearing. A second gear 26 is sleeved on the outer surface of one end of the second crushing roller 25. The first gear 24 and the second gear 26 mesh. A second funnel is provided inside the feeding box 1. The second funnel is located above a screen frame 20. A roller is rotatably connected to the bottom of the screen frame 20 through a pin. A fourth support plate is provided on both the front and rear inner side walls of the feeding box 1. The roller is located on the top of the fourth support plate.
[0028] To achieve the effect of crushing and screening concrete raw materials in this rapid concrete feeding equipment, as shown in the attached document... Figure 1-6As shown, this application adopts the following structure: through the cooperation of a first motor 18, a second motor 27, a first crushing roller 19, a first gear 24, a second gear 26, a second crushing roller 25, a screen 21, a turntable 28, a lever 30, a moving plate 29, a screen frame 20, a screen 21, and a first feed pipe 2, during use, the controller starts the first motor 18 and the second motor 27, feeding concrete raw materials into the feeding box 1 through the first funnel. The output end of the first motor 18 drives the first crushing roller 19 and the first gear 24 to rotate. The first gear 24 then drives the second gear 26 meshing with the first gear 24 and the second crushing roller 25. The rotation of the crushing roller 19 and the second crushing roller 25 crushes larger raw materials into smaller particles, which then fall onto the screen 21. The output of the second motor 27 drives the turntable 28 to rotate, which in turn drives the lever 30 to move the moving plate 29. This causes the moving plate 29 to move along the first groove inside the first support plate, reciprocating in motion. The moving plate 29 then drives the screen frame 20 and the screen 21 to screen the crushed raw materials. Materials that meet the requirements fall onto the inner bottom wall of the feeding box 1, while materials that do not meet the requirements enter the first feed pipe 2 from the left side of the screen frame 20. This achieves the effect of crushing and screening the raw materials for concrete in this rapid concrete feeding equipment.

[0031] To achieve the effect of rapid feeding of concrete by re-crushing recycled materials and feeding them quickly, as shown in the attached document... Figure 1-3As shown, this application adopts the following structure: through the cooperation of the first feed pipe 2, the first conveyor 3, the fourth motor 4, the first pulley 5, the first rotating belt 6, the second pulley 7, the second rotating rod 13, the first conveyor blade 14, the first conveyor 3, the third motor 15, the fifth motor 8, the third pulley 9, the second rotating belt 10, the third rotating rod 22, the second conveyor blade 23, the third motor 15, the first rotating rod 16, and the helical blade 17, during use, when non-conforming raw materials fall into the first feed pipe 2, under the action of their own gravity, the non-conforming raw materials enter the first conveyor 3. The output end of the fourth motor 4 drives the first pulley 5 and the first rotating belt 6, the first rotating belt 6 drives the second pulley 7 and the second rotating rod 13, and the second rotating rod 13 drives the first conveyor blade 14, conveying the non-conforming raw materials from the bottom of the first conveyor 3 to the top of the first conveyor 3. The material is fed from the top of the mixer and then back into the feeding box 1 through the first discharge pipe. Unsuitable raw materials are re-crushed. When the material is to be fed into the mixer, the controller starts the third motor 15 and the fifth motor 8. The output of the fifth motor 8 drives the third pulley 9 and the second rotating belt 10. The second rotating belt 10 drives the fourth pulley 11, the third rotating rod 22 and the second conveyor blade 23 to convey the raw material from the bottom of the second conveyor 12 to the top of the second conveyor 12 and then into the mixer through the second discharge pipe. The raw material enters the second feed pipe by its own gravity, which is inevitably slow and may clog the second feed pipe. Therefore, the output of the third motor 15 drives the first rotating rod 16 and the helical blade 17 to push the raw material inside the mixing box into the second feed pipe. This achieves the effect of returning and re-crushing the material and feeding it quickly.
