Description

TECHNICAL FIELD

[0001] The utility model relates to a straw processing technical field, concretely is a kind of straw returning to field integrated device. BACKGROUND

[0002] Traditional straw burning will produce a large amount of harmful gases, such as carbon monoxide (CO), carbon dioxide (CO), nitrogen oxides (NOx) and particulate matter (such as PM2.5 and PM10) etc. These pollutants will cause air quality to decline, haze weather to increase, and cause serious harm to human health and ecological environment. And straw returning to field avoids the burning process, reduces the emission of these harmful gases and particulate matter, and helps to improve atmospheric environmental quality. In addition, there are many microorganisms, insects and other small organisms in the soil, which constitute a complex ecosystem. Straw returning to field provides rich food sources for the organisms in the soil, increasing the soil organic matter content.

[0003] According to the existing straw returning to field process, during straw returning to field operation, straw collection, pretreatment, deep burying and returning to field are needed. Among them, pretreatment mainly refers to cutting or crushing the straw. If the straw returning to field equipment has requirements for the size of the straw, or in order to facilitate the subsequent returning to field operation, the straw needs to be cut. For example, using a straw cutter to cut the straw into small pieces of about 5-10 centimeters. For some hard straws, such as corn straw, it may also need to be crushed to make the texture more uniform, which is more conducive to mixing with the soil and microbial decomposition. Deep burying returns the cut straw evenly on the field surface, and then uses the share of straw returning to field plow to cut into the soil, and buries the straw into the soil at a certain depth (usually 15-25 centimeters). This can allow the straw to be fully decomposed under the action of soil microorganisms, while avoiding the exposure of straw in the air to affect the decomposition rate or interfere with the sowing of the next season's crops.

[0004] This means that a pulverizer, a rotary cultivator, etc. needs to be used when returning straw to the field. At present, the pulverizer, rotary cultivator, etc. used are more and are independently set up. For example, a straw pulverizing and returning to field machine disclosed in a Chinese patent with publication number CN117044481A. Also, for example, a rotary cultivator disclosed in a Chinese patent with publication number CN105594323A. As can be seen from the above-mentioned patents, the pulverizer and rotary cultivator are independently set up, which means that when performing straw returning to field treatment, multiple tractors need to be equipped to provide power for the rotary cultivator and the pulverizer, so that the rotary cultivator and the pulverizer can respectively complete their own tasks. This operation increases the cost of straw returning to field. UTILITY MODEL CONTENTS
