[0010] Beneficial effects

[0011] This invention provides a crusher with multi-stage crushing function. The device is designed with a multi-stage crushing structure. Raw materials are placed into the first chamber, and a reduction motor drives the first and second crushing rollers to rotate relative to each other, crushing the material. The material then falls into the second chamber, along the inclined slope of the bottom of the second chamber, into a screw conveyor, and then back into the first chamber for further crushing. Pulling the first pull plate allows the material to fall out through the first discharge pipe, or pulling the second pull plate allows the material to be crushed again and fall out through the second discharge pipe. This device has a circulating crushing effect, avoiding the problem of substandard materials from the first crushing stage. It can directly discharge the material after the first crushing stage, or allow it to undergo a second stage of crushing, making it more comprehensive and practical. Attached Figure Description

[0016] Please see Figure 1-2 This utility model provides a technical solution: a crusher with multi-stage crushing function, including a crushing box 1, an outer frame 4 on the lower part of the side wall of the crushing box 1, two pairs of support legs 5 on the lower wall of the outer frame 4, a first cavity 2 in the upper part of the crushing box 1, a second cavity 3 in the lower part of the crushing box 1, a connecting port 7 between the first cavity 2 and the second cavity 3, a feed inlet 6 on the upper wall of the first cavity 2, a screw conveyor 8 on the side wall of the crushing box 1, the second cavity 3 and the first cavity 2 respectively connected to the screw conveyor 8, a crushing mechanism in the connecting port 7, a first pull plate 17 and a second pull plate 19 movably inserted on the bottom surface of the second cavity 3, a first discharge pipe 18 directly below the first pull plate 17, and a second discharge pipe 21 directly below the second pull plate 19.

[0017] In this embodiment, the crushing mechanism includes an adjustment cavity 9 formed on the inner wall of the crushing chamber 1. A reduction motor 10 is provided on the side wall of the adjustment cavity 9. A first rotating shaft 15 is provided at the drive end of the reduction motor 10. The first rotating shaft 15 is rotatably connected between the communication port 7 and the side wall of the adjustment cavity 9.

[0022] Example: The device involves placing raw materials into the first chamber 2, covering it with a cover plate, and starting the reduction motor 10 to drive the first rotating shaft 15 to rotate. The rotation of the first rotating shaft 15 drives the first gear 11 and the first crushing roller 13 to rotate. The rotation of the first gear 11 drives the second gear 12 to rotate. The rotation of the second gear 12 drives the second rotating shaft 16 and the second crushing roller 14 to rotate. The first crushing roller 13 and the second crushing roller 14 rotate relative to each other to crush the raw materials. Afterward, the raw materials fall into the second chamber 3 and fall along the inclined slope of the bottom of the second chamber 3 onto the spiral conveyor. Inside the conveyor 8, the screw conveyor 8 is started to lift the raw material back into the first chamber 2 for crushing.
