[0028] Reference Figure 6-Figure 13In this embodiment, a fixing bar 35 is fixedly installed in the crushing bin 34, and a hexagonal column 321 is rotatably installed at the bottom center position of the fixing bar 35 through a bearing. A hexagonal groove 322 is provided at the bottom of the hexagonal column 321, and a hexagonal rod 316 is slidably installed in the hexagonal groove 322. A conical crushing roller 315 is fixedly installed at the bottom of the hexagonal rod 316. The inclination angle of the conical crushing roller 315 is 65°, and crushing teeth 3151 are fixedly installed on the outside of the conical crushing roller 315. The conical crushing roller 315 is located inside the crushing bin 34 and cooperates with the crushing wall 341. The conical crushing roller 315 rotates in the crushing bin 34, and the solid waste can be crushed by the cooperation of the crushing teeth 3151 and the crushing wall 341.

[0029] Specifically, the waste crushing mechanism 3 performs multi-stage crushing and particle size adjustment on construction waste. The conical crushing roller 315 has a 65° cone angle design and embedded crushing teeth 3151 on the surface. Together with the 60° inclined crushing wall 341, it forms a progressive crushing chamber to enhance shear force.

[0030] Reference Figure 6-Figure 13 In this embodiment, an arc surface 319 is fixedly provided on the top of the conical crushing roller 315, and the top arc surface 319 guides the material into the crushing area.

The crushing motor 314 drives the connecting shaft 320 to rotate, and the connecting shaft 320 drives the conical crushing roller 315 to rotate.

[0031] Specifically, the bottom blocking cover 313 is integrated with the crushing motor 314, and the overall lifting and lowering structure is simplified.

[0032] Reference Figure 6-Figure 13 In this embodiment, two sliding rods 317 are fixedly installed on the outer side of the adjusting discharge pipe 312, and balls 3171 are embedded on both sides of the two sliding rods 317. Two slide rails 37 are symmetrically fixedly installed on the inner walls of both sides of the seat hole 36. The two sliding rods 317 are slidably connected to the side walls of the two slide rails 37 through the balls 3171. The two sliding rods 317 slide vertically in the two slide rails 37 to ensure the vertical movement of the conical crushing roller 315. The outer side of the adjusting discharge pipe 312 is obliquely connected to the inclined warehouse pipe 39, and the tail end of the inclined warehouse pipe 39 is fixedly connected to the rectangular tube 391. The top and bottom of the rectangular tube 391 are both installed with pleated plates 392, which are made of plastic and can be folded and retracted.

[0033] Specifically, the hexagonal rod 316 and the hexagonal groove 322 ensure that the conical crushing roller 315 does not rotate or deviate when it is vertically raised or lowered, and the discharge pipe 312 is adjusted to move in the slide rail 37 through the slide rod 317 and the ball 3171, driving the conical roller to rise and fall synchronously.

[0034] The inclined bin tube 39 and the pleated plate 392 form a flexible connection negative pressure system that adapts to height adjustment and maintains sealing.

[0035] Reference Figure 13-15 In this embodiment, the negative dust suppression mechanism 4 includes a conversion bin 41 and a dust collecting bin 42, both of which are fixedly mounted on the top of the vehicle plate 1. A connecting adjustment hole 49 is provided on the side of the conversion bin 41, and the rectangular tube 391 is slidably connected to the side wall of the connecting adjustment hole 49. Two pleated plates 392 are fixedly mounted to the top inner wall and the bottom inner wall of the connecting adjustment hole 49, and are used to seal the inclined bin tube 39 and the connecting adjustment hole 49. The sealed connection is still ensured when the inclined bin tube 39 moves up and down. A circular hole 410 is provided on the top of the conversion bin 41, and a cylinder 43 is fixedly mounted in the circular hole 410. A motor 48 is mounted on the top of the cylinder 43. A rotating shaft 411 is mounted on the output shaft of the motor 48, and a negative pressure spiral blade 412 is fixedly mounted on the outer side of the rotating shaft 411. The negative pressure spiral blade 412 is slidingly connected to the inner wall of the cylinder 43, and the outer side of the cylinder 43 is connected to a curved pipe 44, and the curved pipe 44 is connected to the top of the dust collecting bin 42. The outer side of the dust collecting bin 42 is connected to an outlet pipe 46, and a filter screen 45 is installed in the dust collecting bin 42. The filter screen 45 is fixed by screws and can be removed. A dust collection area 422 is provided in the dust collecting bin 42 for collecting broken dust. A sealing bin cover 421 is installed on the outer side of the dust collecting bin 42 by rotating through a hinge, and a sealing strip is provided on the inner side of the sealing bin cover 421. When the sealing bin cover 421 is closed, it is sealed between the dust collecting bin 42, and the bottom side of the conversion bin 41 is obliquely connected to a rectangular material guide pipe 47, and the bottom of the rectangular material guide pipe 47 is located at the top of the conveyor belt 21.

[0036] Specifically, the negative pressure dust suppression mechanism 4 extracts dust during the crushed material drop process, achieving clean conveyance. A motor 48 drives the negative pressure spiral blade 412 to rotate within the cylinder 43, creating an upward airflow in the conversion chamber 41. This airflow, carrying dust, enters the dust collection chamber 42 through the curved pipe 44. The dust is intercepted by the filter 45, and the clean air is discharged through the outlet pipe 46. The dust-suppressed crushed material then falls through the rectangular guide pipe 47 onto the conveyor belt 21.

[0037] Working method: When in use, the whole can be moved by a tractor, and after being moved to the appropriate position, it is fixed by a hydraulic jack, and the power and controller are turned on. The forklift guides the construction waste into the guide bin 33. Since the inner wall of the guide bin 33 is inclined, the construction waste slides into the crushing bin 34, and the crushing motor 314 drives the connecting shaft 320 to rotate, and the connecting shaft 320 drives the conical crushing roller 315 to rotate. The construction waste is crushed by the cooperation of the crushing teeth 3151 and the crushing wall 341. The crushed construction waste falls into the adjustment discharge pipe 312 through the discharge pipe 342, and is then introduced into the conversion bin 41 through the inclined bin pipe 39. The motor 48 drives the rotating shaft 411 to rotate, and the rotating shaft 411 drives the negative pressure spiral blade 412 to rotate, so that an upward negative pressure airflow is generated in the conversion bin 41, and the dust enters the cylinder 43, and is then introduced into the dust collection bin 42 through the bend pipe 44, blocked and filtered by the filter 45, and collected by the dust collection area 422. The construction waste passes through the rectangular guide pipe 47 At the top of the introduction conveyor belt 21, the servo motor 25 drives the first conveyor roller 22 to rotate, and the second conveyor roller 24 cooperates to drive the conveyor belt 21. The conveyor belt 21 conveys and collects the construction waste. When the size of the construction waste needs to be adjusted, the two linear motors 38 drive the bottom sealing cover 313 and the adjusting discharge pipe 312 to adjust the vertical height. The adjusting discharge pipe 312 drives the inclined bin pipe 39 to slide up and down in the connecting adjustment hole 49. When the inclined bin pipe 39 moves up and down, it still ensures a sealed connection with the connecting adjustment hole 49. The adjusting discharge pipe 312 drives the conical crushing roller 315 to move up and down, adjusts the angle between the conical crushing roller 315 and the crushing bin 34, and then adjusts the crushing size of the construction waste. Adjusting the conical crushing roller 315 upward increases the angle between the conical crushing roller 315 and the crushing bin 34 to increase the crushing size of the construction waste; adjusting the conical crushing roller 315 downward decreases the angle between the conical crushing roller 315 and the crushing bin 34 to reduce the crushing size of the construction waste.

[0038] Example 2 The rest of Example 2 is the same as Example 1, except that: a laser particle size analyzer is installed at the position of the rectangular guide tube 47 to monitor the size of the solid waste crushing in real time, and the linear motor 38 is linked to control the automatic adjustment of the height of the tapered roller to achieve dynamic feedback control of the target particle size. This application includes all the structural shapes, sizes and materials of Example 1, which can be selected and adjusted to meet specific usage conditions. The accompanying drawings are all schematic structural diagrams, and the specific actual sizes can be appropriately adjusted.

[0039] The above is only a preferred specific implementation method of this embodiment, but the protection scope of this embodiment is not limited to this. Any technician familiar with this technical field can make equivalent replacements or changes based on the technical solution and inventive concept of this embodiment within the technical scope disclosed in this embodiment, and they should be covered by the protection scope of this embodiment.
