Determining the optimal value of the slope of the side wall of the deflector in the forage harvester

More than 85% of the cattle and sheep population in our country is owned by households and small farms. In more than 65% of small farms, the cattle population is up to 100, and the sheep population does not exceed 300. At the same time, the country is building fattening and dairy cattle farms to increase livestock production. To increase livestock production in these farms, it is necessary to provide animals with high-quality feed. The main types of feed are silage and silage hay, forage harvesters are used. Today, foreign countries produce grain harvesters of various designs, but most of them are intended for large farms. That is why the price is expensive. And small combines do not regulate the coarseness of the feed grinding during feed preparation. Therefore, we manufactured a model of a small animal forage harvester, equipped it with a feed size adjustment device and determined its optimal parameters. During the experiments, the harvest was collected and chopped while mowing grass with a combine. In addition, when testing the combine while mowing corn, it was noticed that its deflector was blocked. Therefore, the purpose of this project is to determine the optimal size of the deflector side wall when throwing feed back and to the side. Taking a mathematical model of the process that occurs when a device for adjusting the size of the chopping of stalked feed is installed in the combine, i.e., to obtain laws that theoretically determine the size of the product chopping depending on the combine parameters. The results show that the manufactured combine can be used in all animal feed development processes. This condition ensures that this combine is more competitive than other grain harvesters. And the results of theoretical research will increase the status in the scientific community and scientific competition in the country.
