ОЦЕНКА ЭФФЕКТИВНОСТИ ПОЧВООБРАБАТЫВАЮЩИХ РАБОЧИХ ОРГАНОВ ПО КРИТЕРИЮ ИЗНОСОСТОЙКОСТИ

Abstract

Soil is the main means of production in agriculture. Obtaining favorable conditions for the growth and development of cultivated plants is achieved through mechanical tillage: plowing, deep loosening, peeling, milling, cultivation, harrowing, rolling. The quality of soil cultivation, energy costs and the total cost of cultivation directly depend on the design parameters and the condition of the working bodies. The developed technique for evaluating the technical level of the main elements of plow bodies, taking into account their durability, makes it possible to evaluate the resource of shares and dumps at the design stage. The conducted studies show that the wear resistance of the domestic plowshare made of L-53 steel is 14.0 ha, while the plowshare is replaced with an underused blade part. The resource of the reversible chisel is more than 2 times higher than the resource of the L-53 plowshare, and the resource of its blade part is 2 times higher than the resource of the blade part of the domestic plow. However, considering that the blade part of the plow share with a reversible chisel fully uses its resource during the operation of the plow, since it is replaced regardless of the chisel, in fact its resource exceeds the resource of the blade part of the P-702 share by more than 5 times. Specific costs for the replacement of parts of plow bodies, excluding the cost of plows and the wages of machine operators, were reduced by 43 rubles. per unit due to the use of shares with hardfacing and reversible chisels. The obtained economic efficiency of a reversible chisel with a hardfaced plowshare is 1.5 times higher than that of a P-702 serial plowshare.
