Background technique

With the continuous improvement of the living standards of urban and rural residents in my country, the dietary structure is gradually improving, and the demand for dairy products and meat and eggs of cattle and sheep is increasing year by year. Therefore, it is necessary to vigorously develop the production of cattle, sheep and other feed crops, while silage and The harvesting machinery is an important link in this development process. As an important source of feed, crop straw is an important source of feed, and its mechanized harvesting is an important part of the development of animal husbandry. Straw resources in agricultural areas can greatly increase the output of cattle, mutton and milk; it can greatly save feed grain and alleviate the pressure of food demand growth; it can increase the content of organic matter in the soil, improve the soil's ability to store water and fertilizer, and promote grain production; it can also reduce Environmental pollution caused by straw burning has formed a grain-saving animal husbandry production structure, so a large number of green forage harvesters are needed. Currently harvesting and making silage is manned or semi-mechanized. Manual work is very labor-intensive and inefficient. Due to crops such as silage corn, the best harvest period is only a short ten days, and it cannot be completed without enough labor; semi-mechanized work is harvested manually and transported to the yard. The hay cutter cuts and seals the cellar. my country's green fodder processing methods mostly adopt segmental harvesting. Most areas still use manual harvesting or semi-mechanized harvesting. The straw is transported out of the field and then kneaded and crushed. The operation efficiency is low, the labor intensity is high, and the feed quality is poor, which cannot meet the needs of modern large-scale production. The demand of the aquaculture industry is not conducive to the development of the aquaculture industry, and it also increases labor intensity and production costs for large farmers.
