The distribution of stalked particles during the operation of the levelling device
When cattle breeding and keeping, the main factor is to provide animals with the necessary amount of balanced feed. One of the main factors affecting the profitability of livestock production is the quality of roughage. When harvesting hay into bales, balers with a constant volume bale chamber are most often used. In the process of picking up a hay swath, uneven distribution of the swath along the width of the bale chamber is observed. In order to improve the uniformity of distribution of the hay swath across the width of the roll baler, the levelling device in the improved baler is made in the form of two discs with inclined fingers rotating in opposite directions. The study of the trajectories of movement of the stalked particles showed that the displacement of the stalked particles is more intense towards the periphery of the disc. Therefore, the fingers are located on the disc in two rows with a predominant location along the periphery. The analysis of the obtained trajectories makes it possible to establish the basic parameters of the levelling device: the distance between the fingers is 0.15–0.2 m, the degree of compaction when levelling is 20–25%, the angular velocity is 23–30 rad/s, the diameter of the levelling disc is 0.74 m.
