Description

Technical Field

[0001] This utility model relates to the technical field of straw crushing and deep plowing devices, and in particular to an integrated device for straw crushing, returning to the field and deep plowing in black soil. Background Technology

[0002] In agricultural production, straw return to the field is an important soil improvement and nutrient cycling technology. Especially for precious black soil resources, straw return to the field can effectively increase soil organic matter content, improve soil structure, enhance soil fertility, and achieve sustainable agricultural development. Traditional straw return operations usually involve multiple independent steps, such as straw collection, crushing, spreading, and deep plowing into the soil, which require the use of different mechanical equipment to complete each step.

[0003] However, existing operational models have many problems: First, the step-by-step process is cumbersome, requiring multiple field visits, which is not only time-consuming and labor-intensive but also prone to soil compaction. Second, the process of manually or mechanically collecting straw and feeding it into the crushing equipment is inefficient, increasing labor intensity and operating costs. Third, if the crushed straw is not mixed with the deep soil in a timely and even manner, it is difficult to achieve the desired effect of returning it to the field, affecting the growth of subsequent crops. In addition, existing equipment is often single-function and lacks the ability to efficiently integrate straw crushing with deep plowing, making it difficult to meet the urgent need for mechanized and integrated operations in the conservation tillage of black soil.
