Description

Technical Field

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

[0002] The machine is a mechanical equipment developed in recent years for processing the straw of grain crops. If the straw is not completely processed cleanly in the field, it will affect the sowing of crops. The previous method of processing straw was to burn it directly in the field, which caused serious air pollution and easily caused haze to affect people's health. The existing straw burning machine produces a lot of smoke during the burning process of straw due to incomplete combustion, which makes it impossible to promote the equipment for burning straw on a large scale, so that the straw in rural fields can never be processed.
