When the material is crushed, by starting the servo motor 403, the output end of the servo motor 403 drives the adjacent crushing roller 2 to rotate. At this time, the gear 401 at one end of the crushing roller 2 is meshed with the gear 401 at one end of the other symmetrical crushing roller 2, and the two crushing rollers 2 rotate in opposite directions to crush the material. The crushed material falls on the surface of the screening filter plate 7 through the conical groove 501 in the middle of the receiving plate 5 for screening, and the fine material is discharged from the second connecting pipe 1001 to the outside of the grinding box 1 through the receiving hopper 10 just below the screening filter plate 7, and the large particles are introduced from the discharge port 102 into the interior of the sand storage box 103 through the inclined surface on the top of the guide plate 9 for crushing and crushing again until it is completely crushed.

[0024] See also Figure 1 In an embodiment of the utility model: the shaking assembly 8 includes: a turntable 801 and a connecting rod 803, the turntable 801 is fixedly installed at the end of the other end of the adjacent crushing roller 2, the side wall of the turntable 801 is fixedly connected with an arc-shaped protrusion block 802, and two connecting rods 803 are provided. The two connecting rods 803 are symmetrically fixedly installed on the surface of the other side of the slide plate 6, and one end of the connecting rod 803 movably penetrates to the outside of the other side of the grinding box 1, and a triangular plate 804 is fixedly connected between one ends of the two connecting rods 803.

During the rotation of the crushing rollers 2, the turntable 801 at the other end of a group of crushing rollers 2 rotates, causing the arc-shaped protrusion block 802 on the side wall of the turntable 801 to intermittently squeeze on the inclined surface of the triangular plate 804, so that the triangular plate 804 pushes the slide plate 6 fixed at the other end of the two connecting rods 803 to move away from the triangular plate 804, and the return spring 805 is squeezed and contracted under force. When the arc-shaped protrusion block 802 rotates to contact and press the inclined surface of the triangular plate 804, the return spring 805 is elastically reset after being stressed and quickly drives the slide plate 6 at the other end of the connecting rod 803 to approach one side of the triangular plate 804, so that the slide plate 6 hits the inner wall of the grinding box 1, causing the screening filter plate 7 obliquely installed on the other side of the slide plate 6 to vibrate.

When the reset spring 805 pushes the triangular plate 804 to move to the bottom of the arc-shaped protruding block 802, the fixing ring 806 is placed on the inner wall of the grinding box 1 to limit the movement of the connecting rod 803, so that the arc-shaped protruding block 802 can be smoothly pressed on the inclined surface of the triangular plate 804 when it rotates next time.

[0026] Working principle: Turn on the power supply, and when the concrete mortar raw materials are being crushed by the grinding machine, pour the concrete mortar raw materials to be processed into the interior of the sand storage box 103, and start the drive motor 304, so that the output end of the drive motor 304 drives the auger rod 302 to rotate. Since the lower end of the auger rod 302 extends to the inner bottom surface of the sand storage box 103, the materials in the sand storage box 103 are transported to the upper end of the fixed cylinder 301. After the materials are transported to the upper end of the fixed cylinder 301, the materials are introduced into the first connecting pipe 305. The material is fed into the feed hopper 101 and falls from the feed hopper 101 on the surface between the two crushing rollers 2. At the same time, by starting the servo motor 403, the output end of the servo motor 403 drives the adjacent crushing roller 2 to rotate. At this time, the gear 401 at one end of the crushing roller 2 is meshed with the gear 401 at one end of the other symmetrical crushing roller 2. The two crushing rollers 2 rotate in opposite directions to crush the material. The crushed material passes through the conical groove 501 in the middle of the receiving plate 5 and falls on the surface of the screening filter plate 7 for screening. Fine materials pass through the screening filter plate The receiving hopper 10 directly below 7 is guided out of the second connecting pipe 1001 to the outside of the grinding box 1, and the large particles are guided into the sand storage box 103 from the discharge port 102 through the inclined surface on the top of the guide plate 9 for further crushing and rolling until they are completely crushed. At the same time, during the rotation of the crushing rollers 2, the turntable 801 at the other end of a group of crushing rollers 2 rotates, so that the arc-shaped protrusions 802 on the side wall of the turntable 801 are intermittently pressed on the inclined surface of the triangular plate 804, so that the triangular plate 804 pushes the other ends of the two connecting rods 803. The fixed slide plate 6 moves away from the triangular plate 804, and the reset spring 805 is squeezed and contracted by force. When the arc-shaped protrusion block 802 rotates to contact and press the inclined surface of the triangular plate 804, the reset spring 805 is elastically reset after being stressed and quickly drives the slide plate 6 at the other end of the connecting rod 803 to the side of the triangular plate 804, so that the slide plate 6 hits the inner wall of the grinding box 1, so that the screening filter plate 7 installed obliquely on the other side of the slide plate 6 vibrates. This method is repeated repeatedly to speed up the screening of the material on the surface of the screening filter plate 7.
