A STUDY OF THE WORKING PROCESS OF A TWO-TRACK HARROW

Аннотация

The following article presents the results of theoretical and experimental studies aimed at improving the performance of two-track harrows, that is two series of sequential fixed harrows. In theoretical studies, the question of ensuring their stable movement and, therefore, improving performance is considered by reducing the torsion moment, which leads to a violation of the equilibrium state of the harrow in the process of working a two-track harrow. In experimental studies, however, based on the results of theoretical studies, Uz Dst 3412: 2019 “Testing agricultural techniques. Machines and equipment soil surface treatment. Testing program and methods” and Uz Dst 3193: 2017 “Testing of agricultural machinery. Based on the method of energy evaluation of machines”, the processing depth of the two-track harrow, the quality of soil abrasion, the average quadratic deviation of the heights of irregularities on the surface of the field, the influence of the steep distance between their existing and reduced connecting points on the resistance of the harrow are studied. According to the results obtained, it is noted that the connecting points of the two–track harrow, located on the first and second rows, should be lowered by at least 50 mm compared to the existing cases.
