Abstract

The utility model relates to an improved straw shredding returning machine (Figure. 4) which belongs to the agricultural machinery. The straw shredding returning machine comprises a flail knife of parts, a fixed knife, a rectangular box body, a running direction, a brattice and a main axle, wherein the flail knife runs forwards along with the main axle in a star shape so that the straws in the machine casing run for 225 degrees to be continuously beaten to the fixed knife for three times for shredding and crushing (Attached figure 4 in description), and the operation is safe and no people is hurt. The difference between the technical scheme of the straw shredding returning machine and the prior technical scheme is as follows: the flail knife (Attached figure 1 and 2 in description) of the prior art runs backwards along with the main axle in a star shape so that the straws are beaten behind along the direction of the ground and cannot run for 225 degrees in the machine casing for shredding and crushing, and meanwhile, the opening at the brattice is not sealed, therefore, the operation is not secure and people are easy to hurt. The performance of the original model of the improved straw shredding returning machine is changed by adopting the four technical schemes, i.e., the flail knife, the fixed knife, the rectangular box body and the running direction, thereby the improved straw shredding returning machine becomes the present multi-functional straw shredding returning machine, and the star shape of the original flail knife and the star shape are improved into reversed T shapes.
