Description

Technical Field

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

[0002] Straw return to the field is an efficient and environmentally friendly agricultural farming technology. It buries the remaining straw after crop harvest directly or after processing into the soil, and recycles it as organic fertilizer. This practice can not only effectively reduce the air pollution caused by straw burning, but also significantly improve soil fertility.

[0003] In the past, harvested straw was usually returned to the fields by burning, but now rotary tillers are usually used to crush and bury the straw while plowing the land. However, rotary tillers have poor straw crushing effects, resulting in a large amount of straw not being crushed. Moreover, since the straw is long, it is easy to be entangled in the blades of the rotary tiller, causing the rotary tiller to be unable to operate, resulting in slow efficiency in returning the straw to the fields, thus affecting the subsequent planting of crops. Therefore, it needs to be improved. Utility Model Content
