INFLUENCE OF CHISEL TOOL PARAMETERS AND TRAVEL SPEED ON THE AGROTECHNICAL PERFORMANCE AND TRACTION RESISTANCE

Abstract

The analysis of existing means for the technological process of chiselling is carried out. The results showed that the existing modern technical equipment is not adapted to the soil conditions of the Northern region of Kazakhstan. The Kostanay department of «SPC of agricultural engineering» LLP. conducted studies on substantiation of parameters of the tillage tool of the chisel machine. The results of studies on substantiation of parameters of the tillage tool showed that the tine installed on the shisel tool should be located at a cutting angle of 20 degrees, a width of 50 mm. The thickness of the chisel tool carrier (20 and 30 mm) does not have a significant effect on the agrotechnical performance. The carrier of 30 mm creates traction resistance 15% higher than the carrier of 20 mm. Thus, it is recommended to use for chiselling of the perennial grasses the carrier with a thickness of 20 mm, the tine with a width of 50 mm located at the cutting angle of 20 degrees.
