The stones entering the box body 1 through the feeding port fall onto the plurality of screening rods 3. The stones will slide down along the slope of the screening rods 3. However, as the distance between the screening rods 3 gradually expands, the small-volume stones will directly fall through the gaps between the screening rods 3, while the large-volume stones will slide between the two first crushing rollers 4. The stones crushed by the first crushing rollers 4 fall onto the feeding plate 5 and slide down along the feeding plate 5 between the two second crushing rollers 6. The stones directly falling through the gaps between the screening rods 3 will also be crushed by the second crushing rollers 6. Finally, the stones processed by the second crushing rollers 6 all fall onto the conveyor belt 8 and are discharged through the discharge port 7 at the bottom on the right side of the box body 1.

[0021] At the same time, the distance between every two adjacent screening rods 3 gradually expands from left to right. Baffles 9 are fixedly installed on both sides of the inner wall of the box body 1 on both sides of the plurality of screening rods 3. The distance between the side wall of the baffle 9 and the side wall of the adjacent screening rod 3 gradually expands from left to right, so that the small-volume stones can directly fall through the gaps between the screening rods 3.

[0022] In addition, a feed cover 2 with an upward opening is fixedly installed at the feed inlet on the left top of the box body 1, which facilitates the throwing of stone garbage generated by construction into the box body 1 through the feed cover 2.

[0023] Moreover, a first motor 11 is fixedly installed on the outer wall of the box body 1. The output end of the first motor 11 is fixedly connected to the rotating shaft at one end of one of the first crushing rollers 4. The rotating shafts at the other ends of the two first crushing rollers 4 both penetrate through the side wall of the box body 1, and first gears 12 are fixedly installed on the rotating shafts of the two first crushing rollers 4 penetrating through the side wall of the box body 1. The side walls of the two first gears 12 are meshed with each other. The first motor 11 can provide power for the rotation of the first crushing rollers 4. Under the action of the two first gears 12, the two first crushing rollers 4 can crush large-volume stones.

[0024] And, a second motor 13 is fixedly installed on the outer wall of the box body 1. The output end of the second motor 13 is fixedly connected to the rotating shaft at one end of one of the second crushing rollers 6. The rotating shafts at the other ends of the two second crushing rollers 6 both penetrate through the side wall of the box body 1, and second gears 14 are fixedly installed on the rotating shafts of the two second crushing rollers 6 penetrating through the side wall of the box body 1. The side walls of the two second gears 14 are meshed with each other. The second motor 13 can provide power for the rotation of the second crushing rollers 6. Under the action of the two second gears 14, the two second crushing rollers 6 can crush small-volume stones.
