[0037] In the present invention, a preferred implementation is: first pour the garbage through the feed shell 4, turn on the first motor 9 to rotate the crushing roller 91, and then crush the garbage. When feeding, turn on the fan 1101 to allow the first pipe 1103 to absorb the dust in the feed shell 4 and discharge it through the fan 1101. The extension unit acts as a dust removal component 11 to reduce the pollution caused by dust to the environment, and the crushed material will fall to the surface of the conveyor belt 5.

[0038] Furthermore, a plurality of rolling teeth are formed on the pulverizing roller 91 , and the plurality of rolling teeth are arranged at intervals along the surface of the pulverizing roller 91 .

[0039] Furthermore, the fan 1101 is provided with a dust bag to facilitate the collection of dust generated during crushing.

[0040] Furthermore, a first servo motor 1001 is provided on the side of the shell, and the first servo motor 1001 drives and is connected to a bidirectional screw rod 1003, and the bidirectional screw rod 1003 extends along the width direction of the shell.

[0041] Preferably, different construction waste may have different characteristics, such as hardness, thickness, compressive strength, etc. In the absence of an adjustable crushing degree function, the construction waste may be over- or under-crushed. Over-crushing will cause waste of resources, while under-crushing may affect subsequent recycling. The lack of a function to adjust the crushing degree may result in the inability to personalize treatment of different types of construction waste, thereby affecting the efficiency of recycling. The first servo motor 1001 is used to drive the two crushing rollers 91 to move away from or closer to each other, thereby controlling the distance between the two crushing rollers 91.

[0042] Furthermore, a threaded hole is formed on the thread block 8 corresponding to the bidirectional screw rod 1003, and the thread block 8 is threadedly connected to the bidirectional screw rod 1003. Preferably, the two ends of the bidirectional screw rod 1003 are respectively formed with a positive thread segment and a reverse thread segment with a thread direction opposite to the positive thread segment. The two crushing rollers 91 are both provided with a thread block 8, and the thread blocks 8 on the two crushing rollers 91 are respectively threadedly connected to the positive thread segment and the reverse thread segment. When the first servo motor 1001 drives the bidirectional screw rod 1003 to rotate, the thread block 8 moves toward or away from the center of the bidirectional screw rod 1003, so that the crushing rollers 91 move in a direction away from each other or toward each other, so that the spacing between the crushing rollers 91 is adjustable to change the crushing depth of the construction waste.

[0043] Furthermore, a connecting groove 7 is formed on the side of the shell, and the connecting section is slidably arranged in the connecting groove 7. Preferably, the length of the connecting groove 7 is adapted to the length of the bidirectional screw rod 1003.

[0058] The following is an explanation of the use of a construction waste crushing device for green construction according to the present invention.

[0059] First, the garbage is poured in through the feed shell 4. At this time, the guide plate 41 limits the garbage and guides it to the inner cavity of the positioning shell 3. Then, the first motor 9 is turned on to rotate the crushing roller 91 to crush the garbage. However, when feeding, the fan 1101 is turned on to make the first pipe 1103 adsorb the dust in the feed shell 4 into the filter shell 1102, and then filter it through the filter plate 1107. After the crushed material is completed, it will fall to the surface of the conveyor belt 5. At this time, the dust generated during the descent can also be sucked into the second dust inlet shell 1106 through the second pipe 1105, and then filtered through the filter plate 1107, and finally filtered through the fan 1 101 is discharged, thereby reducing the pollution caused by dust to the environment. However, when the user needs to adjust the depth between the two crushing rollers 91, the second servo motor 501 can be driven to drive the bidirectional screw rod 1003 through the driving end of the first servo motor 1001 to make the transmission wheel 1004 cooperate with the transmission wheel 1004 on the other side to rotate. At this time, the transmission wheel 1004 on the other side will drive the bidirectional screw rod 1003 on the other side to rotate, and then the two bidirectional screw rods 1003 are rotated at the same time to make the threaded block 8 drive the first motor 9 to move and adjust, so as to facilitate the adjustment of the crushing depth, so as to make corresponding adjustments according to the garbage situation.

[0060] The present invention is described in detail above in conjunction with the embodiments of the accompanying drawings.
