Abstract

The invention discloses a soil straw mixing agitator, a spiral conveying unit and a mixing agitation method, and belongs to the technical field of agricultural machinery and fertilizer returning to the field. According to the soil straw mixing agitator, a deep rotation mixing and soil breaking unit and the spiral conveying unit are sequentially arranged from front to back along the advancing direction of the soil straw mixing agitator; the deep rotation mixing and soil breaking unit comprises a first rotation shaft and deep rotation scoops uniformly distributed on the first rotation shaft; thespiral conveying unit comprises a second rotation shaft and two spiral blades symmetrically distributed on the second rotation shaft, the two spiral blades are opposite in spiral directions, and slotholes are uniformly distributed on the spiral blades; the second rotation shaft reversely rotates when the soil straw mixing agitator advances. The idea of pushing straws from a ground surface to anunderground space into grooves and burying the straws is put forward, the mixing agitator and the spiral conveying unit for implementing the scheme are designed, and the problem of the influence of excessive local straws in a soil layer on seeding operation quality is solved.

Description

technical field [0001] The invention relates to a soil straw mixing mixer, a screw transmission unit and a mixing and mixing method, which belong to the technical field of agricultural machinery and fertilizer returning to field. Background technique [0002] Since the 1980s, with the substantial increase in my country's grain production, the amount of straw has also increased significantly; coupled with the popularization and application of central heating and liquefied petroleum gas, a large amount of straw has begun to remain in rural areas. If the straw is thrown directly on the ground to decompose naturally, the planting of the next season's crops will be affected due to the limited decomposition speed. It can be seen that how to deal with the remaining straw has become an urgent problem to be solved in agricultural production. [0003] Due to the huge amount of remaining straw, the high transportation cost and the inability of livestock to eat it all, straw burning ha...
