Technical Field

The invention relates to the field of agricultural machinery, in particular to a straw returning treatment device.

Background

The field returning of the straws is a soil fertility increasing and yield increasing measure which is generally regarded as important in the world at present, and the effects of increasing the fertility and increasing the yield are achieved while the atmospheric pollution caused by the burning of the straws is avoided, but the field returning of the straws is rapidly popularized. When the straws are returned to the field, the crushed straws cover the surface of the farmland, the covered straws can cause great resistance to the rotary tillage cutter when the soil is turned over, and the straws can lead to the soil being overhead after being returned to the field, so that the soil is blown out and leaked, and finally the problems of seedling death and seedling weakness are caused. The conventional treatment method is to improve the crushed particle size of the straws, and the common scheme is to improve the rotating speed of the crushing roller, but the conventional method needs to use a transmission mechanism with higher rotating speed, and the transmission mechanism with higher rotating speed has larger volume, so that the method is only suitable for flat areas planted in large areas, and a new solution is needed to treat the problem caused by returning the straws to the field in hilly areas.
