Self-propelled straw steam explosion extrusion cracking direct returning machine and returning method

Abstract

The invention relates to a self-propelled straw steam explosion extrusion cracking direct returning machine. The returning machine comprises a walking device and a power device, wherein the power device is arranged on the walking device, and the returning machine further comprises a grains picking device, a conveying device, a crushing device, a feeding device before steam explosion and extrusion,and an extrusion device, wherein the grains picking device is positioned in front of the walking device, the grains picking device is connected with the crushing device through the conveying device,and the crushing device is connected with the extrusion device through the feeding device before steam explosion and extrusion. The invention also relates to a returning method of the self-propelled straw steam explosion extrusion cracking direct returning machine. Through unique design, the steam explosion extrusion device can be effectively applied to the field straw treatment, at the same time,the steam explosion extrusion device can be improved, so that the straw is extruded and cracked, the straw direct returning is facilitated, at the same time, the processing capacity is large, the continuous feeding does not cause the problem of accumulation and blockage, and the throwing speed can keep up with the field walking, which is convenient for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and its application, and relates to a self-propelled straw steam explosion puffing and cracking direct field returning machine and a field returning method. Background technique [0002] my country is a large agricultural country with a huge amount of crop straw. According to statistics, there are 900 million tons of straw produced every year. In recent years, in order to make more effective use of crop straws, the Ministry of Agriculture of my country has vigorously promoted the technology of returning straws to fields all over the country. Therefore, regardless of environmental protection or the requirements of sustainable development of modern agriculture, it is imperative to return crop straw to the field. The waste of resources, and more importantly, the return of crop straw to the field is the only way for the sustainable development of agriculture. Regarding the ways of returning str...

Problems solved by technology

[0005] The first purpose of the present invention is to provide a self-propelled steam-explosion puffing cracking and direct returning machine to overcome the problem that the current steam-explosion puffing processing equipment can only be used indoors, and the processing capacity is small and continuous feeding is easy to occur. Material blockage, accumulation, can not be directly applied to the field to deal with the problem of straw
