Abstract: [Objective] To solve the problems of high energy consumption, large particle size, and complex structure of hammer type straw crusher, and meet the needs of modern straw crushing. [Method] Theoretical analysis and design calculations were conducted on the shear type straw crusher. The crushing mechanism, motor power selection calculation, and rotation radius of the shear type straw crusher were studied. The main parameter design was completed and corresponding experimental verification was carried out. [Result] The shear type straw crusher designed in this study has an hourly straw processing capacity, total motor power, spindle speed, and rotation radius of 8 t, 60 kW, 30 r/min, and 0.1 m, respectively, meeting the design requirements of a total motor power not exceeding 78.4 kW and an hourly straw processing capacity of 8 t. [Conclusion] The straw crusher designed using shear optimization method has lower energy consumption, higher efficiency, and smaller dust, which can meet the needs of a large amount of straw crushing. It can provide reference for further innovative research and efficient application of straw crushing equipment and crushing technology.
