The output shaft of the driving motor 3 extends into the pulverizing chamber 21 and is fixedly connected to the rotating shaft of one of the pulverizing rollers 22.

[0036] As an embodiment of the present invention, it also includes a filtering mechanism, which is used to extract dust from the air inside the shell 1. The filtering mechanism includes two L-shaped mounting plates 4 symmetrically fixedly connected to the front side of the shell 1, and the opposite sides of the two L-shaped mounting plates 4 are fixedly connected to piston cylinders 5. The two piston cylinders 5 are slidably connected to the first piston plates 19. The front side of the shell 1 is provided with a circular frame 6 that can slide left and right.

The right side of the second filter screen 30 is elastically connected to the right side wall of the rectangular slide groove by a second spring 32. An electromagnet 31 is installed on the left side wall of the filter box 15. By utilizing the cooperation of the first filter screen 29 and the second filter screen 30, during the filtering operation, the two filter screens are staggered, so that the overall filter hole is smaller. When not filtering, the two filter screens are completely overlapped and the filter hole is larger, that is, the filter hole is not completely blocked at this time, which facilitates the flushing operation.

[0038] As an embodiment of the present invention, it also includes a cleaning mechanism, which is used to clean the filter mechanism. The cleaning mechanism includes an air cylinder 12 fixedly connected to the upper end of the filter box 15, and a through port 13 is opened at the upper end of the air cylinder 12. A second piston plate 26 that can slide up and down is provided in the air cylinder 12. The upper end of the second piston plate 26 is elastically connected to the inner top of the air cylinder 12 through a first spring 25. The left side space of the piston cylinder 5 on the left is connected to the outside through the first one-way port 10. The left side space of the piston cylinder 5 on the left is connected to the first one-way pipe 9. The other end of the first one-way pipe 9 is connected to the external water tank. The left side space of the piston cylinder 5 is connected with the bottom space of the air cylinder 12 through the second one-way tube 11. One-way valves are installed inside the first one-way port 10, the second one-way port 20, the first one-way tube 9, the second one-way tube 11 and the third one-way tube 18. The one-way valve inside the first one-way port 10 flows from left to right, the one-way valve inside the second one-way port 20 flows from left to right, the one-way valve inside the first one-way tube 9 flows from the outside to the left piston cylinder 5 in one direction, the one-way valve inside the second one-way tube 11 flows from the left piston cylinder 5 in one direction to the air cylinder 12 in one direction, and the one-way valve inside the third one-way tube 18 flows from the filter box 15 in one direction to the right piston cylinder 5;

[0039] As an embodiment of the present invention, the inner bottom space of the air cartridge 12 is connected to the top space of the filter box 15 through the first connecting port 27, and the inner bottom space of the filter box 15 is connected to the outside through the second connecting port 28. Normally open solenoid valves are installed inside the first connecting port 27 and the second connecting port 28. The normally open solenoid valves, the electromagnet 31 and the drive motor 3 are opened and closed synchronously.

[0040] In the present invention, during the crushing process, the operator adds construction waste into the crushing chamber 21 through the feeding port 2 on the housing 1, the drive motor 3 is started, and its output shaft drives one of the crushing rollers 22 to rotate. Since the rear ends of the two crushing rollers 22 are both equipped with mutually meshing transmission gears 14, when one crushing roller 22 rotates, the other crushing roller 22 also rotates synchronously, forming a counter-crushing effect. The construction waste is crushed into smaller particles under the squeezing and shearing action of the crushing rollers 22. The crushed particles fall through the chute 23 and are finally discharged from the discharge port 24, ready for the subsequent brick making process.

[0041] During the crushing process, the driving motor 3 drives the incomplete gear 7 to rotate, and the incomplete gear 7 cooperates with the tooth surface of the circular frame 6 to make the circular frame 6 reciprocate left and right on the shell 1. The movement of the circular frame 6 drives the first piston plate 19 in the two piston cylinders 5 to slide back and forth through the piston rod 8. When the first piston plate 19 moves left and right, the use of the third one-way tube 18 and the internal one-way valve will generate a one-way airflow between the drop chute 23, the filter box 15, the right piston cylinder 5 and the outside world. The one-way airflow can draw away the air inside the shell 1, and the shell 1 will replenish gas from the feeding port 2 and the discharge port 24 to generate an airflow. The airflow can suppress the diffusion of dust, but the dust on the inner wall of the shell 1 will follow the one-way airflow, be filtered by the first filter 29, and remain in the filter box 15;

[0042] At the same time, when the first piston plate 19 on the left side moves left and right, air and water are drawn in from the outside through the first one-way port 10, the first one-way tube 9 and the second one-way tube 11, and pressed into the bottom space of the air reservoir 12, pushing the second piston plate 26 to move upward and compressing the first spring 25 (at this time, the two normally open solenoid valves are energized and closed, and the first connecting port 27 and the second connecting port 28 are sealed). When the crushing operation is completed, the two normally open solenoid valves are opened, and the first connecting port 27 and the second connecting port 28 are connected. At this time, the water is released first, and then the gas is released. The water release will backflush the first filter screen 29 and the second filter screen 30, clearing the blockage and discharging the sewage from the second connecting port 28. The gas release will use gas backflush to dry the first filter screen 29 and the second filter screen 30 while cleaning, so as to avoid the situation where their service life is reduced in a wet state;

[0043] In addition, it should be noted that an electromagnet 31 is installed on the left side wall of the filter box 15. By utilizing the cooperation of the first filter screen 29 and the second filter screen 30, during the filtering operation, the electromagnet 31 is energized, the first filter screen 29 moves to the left, and the two filters are staggered, so that the overall filter hole is smaller. When not filtering, the first filter screen 29 is reset under the elastic action of the second spring 32, and the two filters are completely overlapped, and the filter hole is larger, that is, the filter hole is not completely blocked at this time, which facilitates the flushing operation.

[0044] The present invention also discloses a method for using a crushing device for recycling construction waste for brick making, which comprises the following steps:

[0045] Step 1: Prepare the crushed material and move it around the shell 1;

[0046] Step 2: Place a collection box just below the discharge port 24 to facilitate subsequent collection operations;

[0047] Step 3: Start the drive motor 3 to start the crushing operation until the crushing is completed;

[0048] Step 4: Transport the collection box containing the crushed material to the subsequent processing area for further processing.
