Two slide grooves 13 are opened inside the crushing box 2, and the two filter plates 9 are slidably arranged in the two slide grooves 13 in a one-to-one manner.

[0025] By arranging the feeding port 3, the first motor 4, the second motor 5, the first crushing roller 6, and the second crushing roller 7, the first crushing roller 6 and the second crushing roller 7, which rotate in opposite directions, squeeze and crush the raw materials, thereby achieving the purpose of crushing and facilitating operation; by arranging two filter plates 9, double screening can more efficiently improve the screening effect of the materials;

[0026] By setting the electric cylinder 10, the first auxiliary plate 11, the second auxiliary plate 12, and the chute 13, the electric cylinder 10 is started to push the first auxiliary plate 11, the second auxiliary plate 12, and the filter plate 9 toward the chute 13 and move out of the crushing box 2. When the second auxiliary plate 12 is extended out of the crushing box 2, the filter plate 9 is rotated downward at a certain angle. At this time, it is convenient for the staff to clean the materials on the filter plate 9 downward through the inclined surface, which is more convenient for the staff to collect the materials and reduce the labor intensity of the staff.

[0027] By setting two filter plates 9, when one of the filter plates 9 slides out of the crushing box 2 for cleaning, the material can still be screened normally through the filtering effect of the second filter plate 9, so there is no need to stop the operation of the device, reducing the loss caused by the power supply of the switching device; by setting the slider 8, the second crushing roller 7 is driven to approach or move away from the first crushing roller 6, thereby adjusting the gap between the first crushing roller 6 and the second crushing roller 7, and adjusting the crushed particle size of the raw material.

[0028] like Figure 1 and Figure 2As shown, the first motor 4 is fixedly arranged on the side wall of the crushing box 2, the output end of the first motor 4 is connected to the first transmission shaft 14, the first transmission shaft 14 rotates and passes through the side wall of the crushing box 2, and the first crushing roller 6 is fixedly sleeved on the rod section of the first transmission shaft 14 arranged inside the crushing box 2; the output end of the second motor 5 is connected to the second transmission shaft 15, the second transmission shaft 15 rotates and passes through the side wall of the crushing box 2, and the second crushing roller 7 is fixedly sleeved on the rod section of the second transmission shaft 15 arranged inside the crushing box 2; the side wall of the crushing box 2 is fixedly provided with two mounting blocks A screw rod 17 is rotatably provided between the two mounting blocks 16, one end of the screw rod 17 extends out of one of the mounting blocks 16 and is fixed with a handle 18, the slider 8 is threadedly connected to the screw rod 17, and a horizontal movable groove 34 is opened on the side wall of the crushing box 2, the second transmission shaft 15 is horizontally slidably arranged in the movable groove 34, and a limiting rod 19 is also fixed between the two mounting blocks 16, the slider 8 is slidably sleeved on the limiting rod 19, and the other end of the second transmission shaft 15 is fixedly sleeved with a sliding block, which is slidably arranged on the inner wall of the crushing box 2.

[0029] By holding the handle 18 and rotating the screw 17, the slider 8, the second motor 5, the second transmission shaft 15 and the second crushing roller 7 are driven to move horizontally, thereby realizing the movement of the second crushing roller 7, which is convenient for operation.

[0030] like Figure 1 As shown, each filter plate 9 includes a filter screen 21, two working blocks 22, and a spring 20. The outer periphery of the filter screen 21 is connected to a square frame. The two working blocks 22 are arranged on both sides of the filter screen 21, and the upper and lower portions of the two working blocks 22 are connected to the filter screen 21 by springs 20. A vibrator 23 is fixed to the inner wall of the crushing box 2. The output end of the vibrator 23 is used to intermittently abut the filter screen 21. The two working blocks 22 are horizontally slidably arranged on the inner wall of the crushing box 2. When the vibrator 23 is activated, the filter screen 21 is driven to vibrate vertically, thereby specifically achieving the screening effect of the material.

[0031] The base 1 is provided with a cylinder 24 , with the telescopic end of the cylinder 24 facing upwards, for supporting the two filter plates 9 and pushing the two filter plates 9 to rotate.

[0032] When the upper filter plate 9 needs to be cleaned, the telescopic end of the cylinder 24 is initially at the same height as the bottom of the filter plate 9; when the lower filter plate 9 needs to be cleaned, the telescopic end of the cylinder 24 is initially at the same height as the bottom of the filter plate 9;

[0033] During the process of the filter plate 9 moving out of the crushing box 2, the bottom of the filter plate 9 gradually contacts the telescopic end of the cylinder 24, so that the telescopic end of the cylinder 24 supports the filter plate; when the second auxiliary plate 12 extends out of the crushing box 2, the telescopic end of the cylinder 24 contracts, driving the filter plate 9 to rotate downward; the telescopic end of the cylinder 24 extends to push the filter plate 9 to rotate upward, and pushes the filter plate 9 to be level with the slide 13.

[0034] like Figure 1 and Figure 2 As shown, a first material collecting box 25 is provided on the base 1 , and the top of the first material collecting box 25 is open for collecting materials sliding down from the two filter plates 9 .

[0035] like Figure 1 As shown, the side wall of the crushing box 2 is fixedly provided with a third motor 26, and the output end of the third motor 26 is connected to a third transmission shaft 27, and the third transmission shaft 27 rotates and passes through the side wall of the crushing box 2. The crushing box 2 also rotates with a fourth transmission shaft 28, and the third transmission shaft 27 and the fourth transmission shaft 28 are fixedly provided with a rotating roller 29, and the two rotating rollers 29 are provided with a belt 30, and the belt 30 is provided under the two filter plates 9; the side wall of the crushing box 2 is provided with a discharge port 31, and the discharge port 31 is fixedly provided with an inclined discharge plate 32, and the higher side of the discharge plate 32 faces the belt 30, and the base 1 is also provided with a second collecting box 33, and the top of the second collecting box 33 is open for collecting materials that slide down from the discharge plate 32.

[0036] The third motor 26 is started to drive the two rotating rollers 29 and the belt 30 to rotate, so that the materials dropped from the two filter plates 9 can be transported. This specific way of collecting materials reduces labor intensity.

[0037] Working principle:

[0038] When in use, the first motor 4 and the second motor 5 are started, the output end of the first motor 4 drives the first transmission shaft 14 and the first crushing roller 6 to rotate, and the output end of the second motor 5 drives the second transmission shaft 15 and the second crushing roller 7 to rotate, and the first crushing roller 6 and the second crushing roller 7 rotate in opposite directions; then the raw material is poured into the crushing box 2, and the first crushing roller 6 and the second crushing roller 7 squeeze and crush the raw material;

[0039] The crushed raw materials fall onto the filter screen 21 of the filter plate 9. At this time, the two vibrators 23 are started. The telescopic ends of the two vibrators 23 cooperate with the springs 20 to push the two filter screens 21 to vibrate vertically, thereby screening the materials.

[0040] After being filtered by the two filter plates 9, the material falls onto the belt 30. At this time, the third motor 26 is started. The output end of the third motor 26 drives the third transmission shaft 27 and the corresponding rotating roller 29 to rotate. The rotation of the rotating roller 29 drives the belt 30 and the other rotating roller 29 to rotate, thereby conveying the material on the belt 30.

[0041] When the belt 30 conveys the material to the discharge port 31 , the material falls into the second collecting box 33 through the discharge plate 32 and is finally processed uniformly by the staff.

[0042] When it is necessary to adjust the particle size of the raw material, hold the handle 18 and rotate the screw 17. The rotation of the screw 17 drives the slider 8, the second motor 5, the second transmission shaft 15, the second crushing roller 7, and the sliding block to move horizontally in the sliding groove 34 and the inside of the crushing box 2, so that the second crushing roller 7 approaches or moves away from the first crushing roller 6.

[0043] When the filter plate 9 needs to be cleaned, the air cylinder 24 is first started, and the telescopic end of the cylinder 24 is extended to the initial state; then the electric cylinder 10 is started, and the telescopic end of the electric cylinder 10 is extended to push the first auxiliary plate 11, the second auxiliary plate 12, and the filter plate 9 toward the chute 13 and move out of the crushing box 2. During the process of the filter plate 9 moving out of the crushing box 2, the bottom of the filter plate 9 gradually contacts the top of the telescopic end of the air cylinder 24, so that the telescopic end of the air cylinder 24 supports the filter plate 9.

[0044] When the second auxiliary plate 12 extends out of the crushing box 2, the cylinder 24 is started to retract the telescopic end of the cylinder 24, driving the filter plate 9 to rotate downward. At this time, the filter plate 9 is tilted toward the opening of the first collecting box 25. The staff sweeps the material on the filter plate 9 downward through the inclined surface and processes the material in the first collecting box 25 uniformly.

[0045] Then start the air cylinder 24, so that the telescopic end of the cylinder 24 extends to push the filter plate 9 to rotate to the level of the corresponding chute 13; finally start the electric cylinder 10, and the telescopic end of the electric cylinder 10 contracts to drive the filter plate 9 to move into the crushing box 2 to continue screening the material. From then on, the whole operation is completed.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
