Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a straw returning device. Background Art

[0002] During the process of crop planting, some straws will be generated, such as wheat, cotton, corn, etc., among which corn straw is the most common. The most common ways to deal with straw are burning straw and returning straw to the field. Burning straw causes great environmental pollution and has been prohibited in most areas; returning straw to the field can increase soil fertility, improve soil properties and accelerate the maturation of raw soil, and is widely used. In the prior art, a straw pulverizing and returning machine is often used for straw returning. The existing straw pulverizing and returning machine usually consists of a housing, a suspension, a gearbox, a pulverizing roller and a leveling roller. After the straw is pulverized by the pulverizing roller, it is discharged from the rear of the housing and compacted and leveled by the leveling roller. However, during the use process, when the pulverized straw and soil are discharged from the rear of the housing, dust is likely to occur, which affects the leveling effect of the leveling roller on the one hand and pollutes the environment on the other hand.
