[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a device for crushing and returning rice and rapeseed straw to the field. Background Technology

[0002] Returning straw to the field is an important measure for achieving sustainable agricultural development, as it can increase soil organic matter and improve soil structure. However, there are some problems in the process of crushing and returning rice and rapeseed straw to the field: First, the straw may contain pathogens and insect eggs, and direct return to the field can lead to the spread of pests and diseases; second, when the straw has a high moisture content, it is prone to mold after being returned to the field, affecting the effectiveness of the return.

[0003] A straw crushing and returning device, authorized by announcement number CN108575326B, belongs to the field of agricultural machinery. It includes a frame, a straw crushing body, a walking device, a ditching device, and a soil covering and compaction device.
