This work is mainly composed of silo, feeding conveyor, briquetting device, control counter, etc. When working, the shredded straw agricultural by-products are fed into the silo by forklift or grass grabber, and the shredded straw is dropped onto the feeding conveyor belt under the extrusion action of the rotating shaft in the silo and transported to the briquetting machine. Three pressing rollers rotating around the main shaft are arranged in the briquetting machine. Through the action of friction between the rotation of the pressing rollers and the materials, the straw is continuously extruded from the flat die hole. Finally, the straw is cut by hay cutter and dropped to the discharging conveying device for cooling and dehumidifying.

This work through 51 single chip microcomputer control software to control the material feeding amount, spindle speed, molding temperature, at the same time can stop the operation and alarm when the machine fails, which greatly improves the success rate of the straw agricultural by-products, and is of great significance to the development and utilization of new energy.
