AI Technical Summary
Existing straw processing equipment struggles to efficiently separate straw from residual film during the crushing process, resulting in complex structures, high power consumption, high failure rates, and insufficient separation efficiency and integration.
By combining the projectile kinetic energy generated by the crushing mechanism itself with the spatial partitioning layout inside the hopper, the automatic sorting and collection of straw fragments and residual film is achieved by utilizing density differences. The crushing rotor hammer impacts and crushes the material and imparts a projectile velocity. The less dense residual film impurities fly a short distance and fall into the first collection zone, while the more dense straw fragments fly a long distance and fall into the second collection zone.
It achieves efficient and automatic separation of straw fragments and residual film, with a simplified and compact structure, improving the integration and operating efficiency of the device and reducing the need for additional equipment.
