DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Referring to Figures 1-4 , a food detection crushing device includes a crushing box 1. Rotating rods 2 are rotatably connected to the inner walls on both sides of the crushing box 1 symmetrically. Crushing rollers 3 are fixedly sleeved on the outer walls of the two rotating rods 2. Driving rods 4 are rotatably connected to the inner walls on both sides of the crushing box 1 below the rotating rods 2. Cams 5 are fixedly sleeved on the outer walls of the driving rods 4. A first screening block 6 is slidably connected to the inner wall of the crushing box 1 below the driving rods 4;

[0019] A second screening block 7 is slidably connected to the inner wall of the crushing box 1 below the first screening block 6. A fixing block 8 is fixedly connected to the middle position between the first screening block 6 and the second screening block 7 on the inner wall of the crushing box 1. A supporting block 9 is fixedly connected to the lower surface of the first screening block 6 relative to the position of the fixing block 8. One ends of several supporting blocks 9 all penetrate and extend outside the corresponding fixing block 8 and are fixedly connected to the second screening block 7. A plurality of screening holes are evenly penetrated through the upper surfaces of the first screening block 6 and the second screening block 7. The aperture of the screening holes of the first screening block 6 is larger than the aperture of the screening holes of the second screening block 7.

[0020] Wherein, driving motors 10 are fixedly connected to the outer walls of one side of the crushing box 1 relative to the positions of the rotating rods 2 and the driving rods 4. One ends of the two rotating rods 2 and the driving rods 4 all penetrate and extend outside the crushing box 1 through bearings and are fixedly connected to the driving motors 10 through couplings, which is convenient for using the driving motors 10 to drive the rotating rods 2 and the driving rods 4 to rotate.

[0021] Wherein, springs 11 are fixedly connected to the lower surface of the first screening block 6 relative to the positions of the supporting blocks 9. The other ends of several springs 11 are all fixedly connected to the fixing block 8, which is convenient for using the springs 11 to drive the first screening block 6 to move.

[0022] Wherein, openings are penetrated through the outer walls of one side of the crushing box 1 relative to the positions of the first screening block 6 and the second screening block 7, and guide plates 12 are fixedly connected to the openings, which is convenient for discharging the crushed materials.

[0023] Wherein, a discharge pipe 13 is fixedly connected to the inner bottom wall of the crushing box 1, and one end of the discharge pipe 13 penetrates and extends outside the crushing box 1, which is convenient for using the discharge pipe 13 to discharge the crushed materials.

[0024] Wherein, a feeding pipe 14 is fixedly connected to the upper surface of the crushing box 1 relative to the position of the crushing roller 3, and one end of the feeding pipe 14 penetrates and extends into the crushing box 1, which is convenient for pouring the materials to be crushed into the crushing box 1 for crushing.

[0025] When the device is in use, the driving motor 10 is connected to an external power supply through a controller. The material to be crushed is poured into the crushing box 1 through the feeding pipe 14. The driving motor 10 is started to drive the crushing roller 3 to crush the material. The crushed material falls on the first screening block 6. The first screening block 6 and the second screening block 7 screen the material. The screened material is discharged through the discharge pipe 13. The driving motor 10 is started to drive the driving rod 4 and the cam 5 to rotate counterclockwise. One end of the cam 5 pushes the first screening block 6 downward and performs secondary pressing and crushing on the material on the surface of the first screening block 6. The first screening block 6 drives the second screening block 7 to move downward through the support block 9 and compresses the spring 11. When the concave part of the cam 5 rotates above the first screening block 6, the spring 11 pushes the first screening block 6 and the second screening block 7 upward. The second screening block 7 abuts against the fixed block 8, causing the first screening block 6 and the second screening block 7 to vibrate. The material that fails to be screened falls onto the guiding plate 12 and is discharged. The discharged material is poured back into the crushing box 1 for secondary crushing.
