INVESTIGATION OF WEAR IN REJECTED REVERSIBLE CHISEL SHANKS
Abstract
The article presents the results of studying worn and rejected reversible chisel points. It was found that their rejection is caused by excessive wear of the tip (48.29 mm). The use of monometallic reversible chisel points leads to a decrease in their service life due to the formation of wide back bevels (up to 5.4 mm) and an increase in blade edge thickness to critical values. On non-saline soils, when excessive compaction occurs, chiseling with chisel–cultivators ChKU-4 and ChKU-4M is used instead of harrowing. To preserve moisture and prevent harmful salts from rising to the soil surface, in saline-prone areas where leaching irrigation is applied, harrowing is carried out when the soil reaches the proper maturity. After this, the soil is loosened with the ChKU-4 chisel–cultivator to a depth of 16–18 cm or more [1,2].
