Description

Technical Field

[0001] The utility model relates to the technical field of straw cleaning, in particular to a straw cleaning device for a large seedling ridge belt. Background Art

[0002] Straw is a general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining parts of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops after the seeds are harvested. With the development of modern agriculture, the efficiency of crop harvesting has been significantly improved, but the treatment of crop straw after harvest is still an important issue. Due to the low level of agricultural production and low yield in the past, the amount of straw was small. Except for a small amount of straw used for gaskets, feeding livestock, and part of it for composting, most of the straw was burned as fuel. With the advancement of science and technology and the improvement of agricultural mechanization, straw can be processed in a variety of ways to make full use of its resource value, reduce environmental pollution and improve the sustainability of agricultural production. The current problems with traditional straw cleaning are as follows:

[0003] (i) Traditional straw cleaning methods usually require a lot of manual labor. Farmers need to collect, stack and clean the straw manually, which takes a lot of time and human resources. The process usually takes a long time, thereby delaying the preparation of farmland and further affecting the time of agricultural production.

[0004] (ii) Conventional straw return devices may not ensure that the straw is evenly distributed in the farmland. This may result in excessive soil coverage in some areas and less in other areas, thus affecting the uniformity of soil quality and plant growth.

[0005] (3) Traditional straw cleaning devices are mostly horizontal rotary tillers (the rotating axis is parallel to the planting bed). During the rotation process, this type of cleaning device will cause the straw to be brought back to the planting area, which may easily result in poor cleaning effect. If the soil in the area is wet and sticky, it will also adhere to the machine, or further cause device failure and reduce straw cleaning efficiency. Utility Model Content
