Description

A straw crushing and returning machine for agricultural machinery

Technical field

The utility model relates to the technical field of straw returning to the field, and in particular to a straw crushing and returning machine for agricultural machinery.

Background technique

Straw is the general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining parts of wheat, rice, corn, potatoes, rape, cotton, sugar cane and other crops (usually coarse grains) after harvesting the seeds. Straw contains more than half of the products of crop photosynthesis and is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. It is a multi-purpose renewable biological resource and a roughage.

The main ways of directly returning straw to the field include crushing straw and returning it to the field, covering it and returning it to the field with high stubble. At present, high-stubble return with the largest promotion area accounts for about 60% of the total area of direct straw return. Mechanical crushing and compaction and mulching return account for 22% and 18% respectively. Returning straw to the field by turning or mulching it is an effective measure to increase yield.

Among related technologies, crushing straw and returning it to the field can improve the soil structure, loosen the soil, increase porosity, and promote microbial activity and the development of crop root systems. Application number: CN202222255634.4 discloses a straw returning device, which is connected to the agricultural machinery through a lifting frame. The agricultural machinery drives the main pulley to rotate through the belt, and the main pulley drives the transmission rod to rotate. The transmission rod causes multiple spiral blades on the surface to rotate at high speed. The straw and soil are crushed, and the crushed straw is mixed with the soil layer to complete the return of the straw to the field. However, this device is not convenient for multi-stage crushing of straw during use. The device crushes the straw once. When the straw is too long, the straw is not completely crushed. It is not convenient to crush the upright straw, which reduces the straw crushing efficiency and is low. The efficiency of returning straw to the field.

Therefore, it is necessary to provide a straw crushing and returning machine for agricultural machinery to solve the above technical problems.
