The feeding box 5 on the right side has transmission rods 19 rotatably connected to both sides of the interior of the feeding box 5, transmission rollers 20 are fixedly connected to the outside of the transmission rods 19, and a feeding belt 4 is sleeved on the outside of the transmission rollers 20, and a third motor 11 is fixedly connected to the lower side of the front end of the feeding box 5, and a feeding frame is fixedly connected to the right side of the interior of the screening box 1, and a rotating shaft 15 is rotatably connected to the interior of the feeding frame, and a plurality of crushing knives 16 are evenly fixedly connected to the outside of the rotating shaft 15, and a first motor 6 is fixedly connected to the right side of the front end of the screening box 1, and a driving end of the second motor 7 is fixedly connected to the top of the worm 10, and a driving end of the third motor 11 is fixedly connected to the front end of the lower transmission rod 19, and a driving end of the first motor 6 is fixedly connected to the front end of the rotating shaft 15, and the top end of the upper pushing block 21 is rotatably connected to the left side of the bottom end of the upper traction plate 13, and the outside of the feeding belt 4 is attached to the right side outer wall of the screening box 1;

[0032] The concrete raw materials to be screened are placed into the screening box 1 through the feeding barrel 2, and the concrete falls on the top of the screening plate 14. At this time, the second motor 7 is started to drive the worm 10 to rotate, and then the worm 10 is meshed with the worm wheel 8, so that the worm wheel 8 is rotated, thereby rotating the rotating rod 9, and the rotation of the rotating rod 9 drives the traction protrusion 22 to rotate. As the traction protrusion 22 rotates, its outer protruding end contacts the pushing block 21, thereby moving the upper traction plate 13 upward, and the screening plate 14 is tilted by the upper traction plate 13. When the protrusion of the traction protrusion 22 leaves the screening plate 14 and is parallel, the screening plate 14 is moved upward by the continuous rotation of the traction protrusion 22. The screen plate 14 is tilted reciprocatingly, thereby vibrating and screening the concrete. Fine particles flow downward, while large particles flow upward to the inside of the material box 5 as the screening plate 14 tilts. The third motor 11 is started to drive the lower transmission rod 19 to rotate, and the feeding belt 4 is driven to operate through the rotation of the transmission roller 20. The feeding belt 4 rotates in a clockwise direction, and the particles fall on the protrusions on the surface of the feeding belt 4, which are sent into the top notch of the screening box 1 and into the feeding frame. The third motor 11 is started to drive the rotating shaft 15 to rotate, and the concrete is crushed by the crushing knife 16, so that the concrete is evenly screened, and large particles of concrete can be crushed and screened in time, so that the screening efficiency is better and the use is faster and more convenient.

[0034] The screened concrete falls on the top of the discharge plate 17, and as the lower traction protrusion 22 rotates, the protrusion of the lower traction protrusion 22 drives the lower pushing block 21 to push the lower traction plate 18 upward, and as the traction protrusion 22 continues to rotate, the discharge plate 17 is tilted back and forth inside the screening box 1, and the lower traction plate 18 slides inside the discharge plate 17, causing the surface of the discharge plate 17 to vibrate, thereby discharging the surface concrete to the outside through the discharge port 12, and completely discharging the fine-grained concrete to the outside, avoiding the internal concrete from remaining inside the device and reducing the waste of concrete.

[0035] Reference Figure 3 A traction inclined block 3 is fixedly connected to the right side of the top of the screening box 1;

[0036] The large particles pulled up fall more smoothly into the feeding frame through the pulling inclined block 3, thus avoiding accumulation at the gap and ensuring stable crushing.

[0037] Working principle: the concrete raw materials to be screened are put into the screening box 1 through the feeding barrel 2, and the concrete falls on the top of the screening plate 14. At this time, the second motor 7 is started to drive the worm 10 to rotate, and then the worm 10 is meshed with the worm wheel 8, so that the worm wheel 8 is rotated, thereby rotating the rotating rod 9, and the rotation of the rotating rod 9 drives the traction protrusion 22 to rotate. As the traction protrusion 22 rotates, its outer protruding end contacts the pushing block 21, thereby moving the upper traction plate 13 upward, and the screening plate 14 is tilted by the upper traction plate 13. When the protrusion of the traction protrusion 22 leaves the screening plate 14 and is parallel, the screening plate 14 is tilted reciprocatingly through the continuous rotation of the traction protrusion 22, thereby vibrating and screening the concrete, and fine particles flow downward, while large particles flow upward to the inside of the material box 5 as the screening plate 14 tilts, and the first The third motor 11 drives the lower transmission rod 19 to rotate, and drives the feeding belt 4 to operate through the rotation of the transmission roller 20. The feeding belt 4 rotates clockwise, and the particles fall on the protrusions on the surface of the feeding belt 4, and are sent into the top notch of the screening box 1 and into the feeding frame. The third motor 11 is started to drive the rotating shaft 15 to rotate, and the concrete is crushed by the crushing knife 16. The screened concrete falls on the top of the discharge plate 17, and as the lower traction protrusion 22 rotates, the protrusion of the lower traction protrusion 22 drives the lower pushing block 21 to push the lower traction plate 18 upward, and as the traction protrusion 22 continues to rotate, the discharge plate 17 is tilted back and forth inside the screening box 1, and the lower traction plate 18 slides inside the discharge plate 17, causing the surface of the discharge plate 17 to vibrate, thereby discharging the surface concrete through the discharge port 12 to the outside.
