Straw returning centralized incineration device for agricultural machine

Abstract

The invention relates to the technical field of agricultural straw waste processing equipment, in particular to a straw returning centralized incineration device for an agricultural machine, and aimsat solving the technical problems that in the incineration process of an existing device, straw incineration is incomplete, smoke is large, the incineration output rate is not high, and the incineration treatment efficiency is low. In order to solve the technical problems, the straw returning centralized incineration device for the agricultural machine is composed of an incineration tank, a pushing device and an air supply device, spiral blades are matched with an incineration tank for extrusion and pushing, the straw can be continuously compressed along with reduction of the size of the straw, and the stacking density of the straw is kept; and good contact and heating between the straw and the inner wall of a tank body are kept all the time, so that the straw is incinerated more completely, the spiral blades are used for layering and driving the straw, the straw and oxygen are in more sufficient contact, combustion is more sufficient, and through an online combustion manner, the use efficiency is higher, and the treatment rate is higher.

Description

technical field [0001] The invention relates to the field of agricultural straw waste processing equipment, in particular to a centralized incineration device for returning agricultural straw to the field. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining part of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after harvesting the seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, and is a multi-purpose renewable biological resource. [0003] Most of the existing agricultural treatment methods are to make straw into livestock feed, or burn a large amount of straw, and return the ash of the incineration product to the farmland to supplement the soil nutrients of the farmland. [0004] In the process of realizing straw incine...
