AI Technical Summary
⚠Technical Problem
Existing open-pit mining equipment cannot effectively control the particle size of coal, which necessitates the addition of crushing stations, increasing process complexity and reducing mining efficiency.
⚗Method used
Design a multi-stage crushing device, including primary and secondary crushing mechanisms. The material after primary crushing is transported to the secondary crushing mechanism by a scraper conveyor for secondary crushing to ensure that the particle size of the coal meets the standard.
🎯Benefits of technology
It improves coal mining efficiency, ensures that coal particle size meets requirements, eliminates the need for additional crushing stations, and simplifies the mining process.

Abstract
The utility model provides a kind of multistage crushing device and mining machine.First crushing mechanism and second crushing mechanism are respectively arranged in the front and rear of material collecting device, and first crushing mechanism is close to the feed inlet of material collecting device, and conveying groove is arranged in material collecting device, and conveying groove is arranged between first crushing mechanism and second crushing mechanism, and above scraper conveyor, so that the material crushed by first crushing mechanism is conveyed to second crushing mechanism by scraper conveyor for secondary crushing.The material entering the material collecting device can be pre-crushed by first crushing mechanism, and then the material is conveyed to second crushing mechanism for secondary crushing by scraper conveyor through conveying groove, so that the particle size of the material is smaller than the required size.Compared with the existing material collecting device, the present application not only can crush coal during mining, but also can ensure that the particle size of coal is the required size, so the present application can improve the mining efficiency of coal.
