Aiming at the characteristics of the crushed straw, wind conveying is boldly adopted. The power of the fan comes from the power machinery, which has a high degree of automation and no external leakage, which is environmentally friendly and saves raw materials. the

The moving knife group and the fixed knife group adopt a parabola y=x ^-n (n∈[1,3]) curve design. Compared with the traditional linear design, this structure effectively increases the sweeping area of the knife group when it is working. The crescent hook structure is formed on the top of the group, which can effectively hook and pick up irregular straws. The change of the opening of the parabolic fork is more conducive to straw clamping, and the wear-resistant welding rod is used for spraying at the parabolic fork, which improves the efficiency of the crushing knife group. Long service life, reducing maintenance costs.

The utility model can effectively overcome the disadvantages of poor working environment and low production efficiency of traditional manual work and crude equipment, thereby providing users with a more convenient operation mode. the
