The present embodiment will be described in detail below in conjunction with the accompanying drawings:

This embodiment provides a construction waste crushing equipment for construction projects, please refer to FIGS. 1 and 2 in the accompanying drawings together.

As shown in Figures 1 and 2, the construction waste crushing equipment for construction projects includes a preliminary crushing bin 1 with a belt conveyor 14 inside and a rolling drum 3 with legs 2 inside, and the middle part of the belt conveyor 14 is supported at intervals There are a plurality of supporting rollers 15, the two ends of the preliminary crushing bin 1 are provided with openings, and one end is the feeding port, and the other end is the discharging end which is communicated with the rolling cylinder 3. The preliminary crushing bin 1 above the conveying device is fixed inside There are multiple rows of vertical high-frequency vibration crushing heads 4, and the height of the lower end of the high-frequency vibration crushing heads 4 gradually decreases from the feed end to the discharge end. Large pieces of construction waste are first sent to the preliminary crushing bin 1 to pass through. The high-frequency vibration crushing head 4 is used for crushing, such as the crushing head used on the engineering excavator. The height of the lower end of the high-frequency vibration crushing head 4 gradually decreases from the feeding end to the discharging end, and can also be gradually crushed during the conveying process. , the rolling cylinder 3 is arranged vertically, and the center is supported by the supporting plate 5 with a driven extruding plate 7 that rotates around the central fixed column 6 of the supporting plate 5.
