Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, and particularly relates to a cotton straw feeding and cutting device. Background Technique

[0002] Xinjiang is the main cotton planting and production area in the whole country. By the end of 2022, the cotton planting area in Xinjiang exceeded 37 million mu. As a by-product of cotton production, about more than 20 million tons of cotton straw waste are generated in the fields of Xinjiang every year. However, its comprehensive treatment technology is relatively backward, and the utilization rate is less than 1 / 10, resulting in huge resource waste. At present, the resource utilization of crop straws in China is mainly divided into five methods: fertilizer utilization, feed utilization, substrate utilization, raw material utilization, and fuel utilization. These methods all require the straws to be cut first. However, due to the complex composition of Xinjiang cotton straws and the large differences in the physical and chemical properties of each component, the cotton skin has strong toughness and often cannot be directly cut. Therefore, a special cutting device for cotton straw cutting is proposed, which has a simple structure, is easy to use, has safe operation, and low cost. Summary of the Invention
