[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example

[0026] See also Figure 1-5 A construction waste crushing machine comprises a crushing box 1, the outer wall of the crushing box 1 is provided with a discharge pipe 2, and the bottom end of the crushing box 1 is provided with a discharge port, and a crushing device and a screening device are installed inside the crushing box 1.

[0027] The arrangement of the discharge pipe 2 and the discharge port facilitates the discharge of construction waste of different finenesses.

[0028] The crushing device includes a crushing motor 3 and two crushing rollers 4. The crushing rollers 4 are rotatably arranged inside the crushing box 1. The crushing motor 3 is fixedly installed on the outer wall of the crushing box 1. Gears 5 are fixedly connected to the outer walls of the two crushing rollers 4. The two gears 5 are meshed with each other. A transmission sleeve 1 6 is fixedly connected to the outer wall of one of the crushing rollers 4. A transmission sleeve 2 7 is fixedly connected to the output end of the crushing motor 3. A transmission belt 8 is connected between the transmission sleeve 1 6 and the transmission sleeve 2 7.

[0029] When the crushing motor 3 is working, it drives the transmission sleeve 2 7 to rotate, and the transmission sleeve 1 6 is rotated under the transmission action of the transmission belt 8, so that the crushing roller 4 fixedly connected to the transmission sleeve 1 6 rotates, and under the action of the two gears 5, the two crushing rollers 4 can rotate in opposite directions, so that the construction waste can be crushed.

[0030] The screening device includes two groups of fixed blocks 9 and two mounting blocks 10, each of which is provided with two fixed blocks 9.
