It is characterized in that dust removal structures are arranged on both the front and rear sides of the bottom end of the crushing bin 2, and a screening structure is arranged at a corresponding vertical position of the bottom of the dust removal structure.

[0032] The crushing structure further includes a connecting plate 3, a rectangular groove 4, a crushing motor 5, two crushing rollers 6, two gears 7, a feed port 8, and two baffles 9. The bottom end of the crushing bin 2 is connected to a conveying channel 10, and a dust collecting hopper 11 is arranged at the bottom of the conveying channel 10.

[0033] Specifically, the rectangular groove 4 is opened at the top of the frame 1, the connecting plate 3 is arranged at the lower side of the crushing bin 2, and the bottom of the crushing bin 2 passes through the rectangular groove 4, at which time the bottom of the connecting plate 3 is in close contact with the bottom wall of the rectangular groove 4. The connecting plate 3 is connected to the bottom wall of the rectangular groove 4 by bolts and nuts, the crushing motor 5 is installed on one side of the crushing bin 2, and two crushing rollers 6 are arranged inside the crushing bin 2, and the outer convex teeth of the two crushing rollers 6 are staggered. The driving end of the crushing motor 5 is connected to one end of the crushing roller 6, and two gears 7 are arranged on the other side of the crushing bin 2, and the gear 7 is connected to the other end of the crushing roller 6. The feed port 8 is installed at the top of the crushing bin 2, and the walls on both sides of the crushing bin 2 are provided with arc chutes, and the rear ends of the baffle 9 are rotatably connected to the two sides of the feed port 8. The front ends of the baffle 9 are slidably connected to the arc chutes, the top of the conveying channel 10 is connected to the bottom of the crushing bin 2 by flanges, and the dust hopper 11 is arranged at the bottom of the conveying channel 10.

[0034] First, the operator needs to simply cut the environmentally friendly building materials so that the materials can be put into the crushing bin 2 through the feed port 8. The crushing motor 5 is running, and the two gears 7 can cooperate with the two crushing rollers 6 that rotate in opposite directions to crush the materials. And during the crushing process, the second reset spring 32 can push the two baffles 9 to reset through the bar block 31, so that the upper side of the feed port 8 can be blocked. In addition, the dust generated when the building materials are crushed can be blocked and prevented from spreading, thereby reducing the noise generated during the crushing to a certain extent. The inclined guide plate 30 can concentrate the materials on the upper side of the two crushing rollers 6, thereby increasing the crushing effect, and then the crushed materials are discharged through the conveying channel 10.

[0035] The dust removal structure includes a horizontal plate 12 sleeved on the lower side of the conveying channel 10, and a dust collecting bin 13 is arranged on the top of the horizontal plate 12. One side of the dust collecting bin 13 is connected to an exhaust fan 14, and the dust collecting bin 13 is also connected to a connecting pipe 15. A notch is arranged at the front end of the horizontal plate 12. The other end of the connecting pipe 15 passes through the notch and is connected to the dust collecting hopper 11 and the top of the rectangular block 16. The interior of the rectangular block 16 is set to be hollow, and a plurality of circular through holes are arranged at the bottom of the rectangular block 16.

[0036] The screening structure includes a collecting bin 17 installed on the lower side of the frame 1, a screening inlet is provided on the top of the collecting bin 17, a screen 19 for covering the screening inlet is provided above the collecting bin 17, guide rails 18 are provided on both the front and rear sides of the screening inlet, and two sliding blocks 20 slidably connected to the guide rails 18 are provided on both the front and rear sides of the screen 19;

[0037] A transmission frame 21 is provided on the right side of the screen 19. The transmission frame 21 is equipped with a left and right screening mechanism, which includes a screening motor 28 and an eccentric roller 27. The eccentric roller 27 is connected to the output shaft of the screening motor 28. The eccentric roller 27 is located on the right side of the transmission frame 21 and always abuts against the transmission frame 21. The bottom of the transmission frame 21 is slidably connected to the collection bin 17. The right sides of the front and rear ends of the transmission frame 21 are provided with a reset structure for connecting with the top of the collection bin 17. The transmission frame 21 is equipped with a bearing seat 22, which is set to be concave, and the outer side of the eccentric roller 27 is in close contact with the inner wall of the bearing seat 22.

[0038] The reset structure includes two vertical plates 23 spaced apart from each other, and a guide rod 24 is horizontally arranged on the left side of the vertical plate 23. A transmission block 26 is sleeved on the guide rod 24, and a first reset spring 25 is arranged between the transmission block 26 and the corresponding vertical plate 23.

[0039] After the material is crushed, the material will fall to the top of the screen 19 through the conveying channel 10. At this time, the screening motor 28 is running, which can drive the eccentric roller 27 to rotate, and cooperate with the bearing seat 22 to drive the screen 19 and the transmission frame 21 to slide horizontally along the guide rail 18. At the same time, the transmission frame 21 will drive the transmission block 26 to move along the guide rod 24, and stretch the first return spring 25, and with the continuous rotation of the eccentric roller 27. It can drive the screen 19 to reciprocate in the horizontal direction, so that the crushed material can be screened. Since the slag and stone particles remaining after crushing are small, the slag and stone particles will be screened and collected in the collection bin 17, and discharged through the discharge port 33. Larger particles of building materials will enter the guide groove 29 through the opening of the screen 19, and be discharged from the guide groove 29, which is convenient for personnel to collect. The two sliding blocks 20 are used to ensure the stability of the screen 19 during movement, and the vertical plate 23 is used to fix the guide rod 24.

[0040] During the screening process, dust will be generated, and the dust collecting hopper 11 can block the dust. At the same time, the exhaust fan 14 is running to form a negative pressure inside the dust collecting bin 13, and then the dust can be extracted through the through hole at the bottom of the rectangular block 16. The dust is then transported through the connecting pipe 15 and finally enters the dust collecting bin 13 for collection, thereby reducing the harm to the operator.

[0041] After the device is finished running, the operator can separate the connecting plate 3 from the rectangular groove 4. The top of the conveying channel 10 is separated from the crushing bin 2, and then the device can be disassembled as a whole, which is convenient for the operator to perform subsequent maintenance and parts replacement inside the device.
