Test results of the new Root Crop Harvester

Abstract

In the conditions of Uzbekistan, when harvesting early root crops in the summer, the soil moisture is reduced. Therefore, in the process of digging, the soil of the tuberous layer crumbles badly with the formation of large lumps, which makes it difficult to separate them from the tubers on the screen and elevator. This leads to increased loss and damage to root tubers. Serial digging working bodies of existing root crop harvester in the process of digging take away a significant amount of excess soil, and as a result, the tuberous mass is unloaded in front of the ploughshare. Therefore, this scientific research was aimed at developing a more efficient method of harvesting tubers that provides the required quality of work with less energy consumption and greater productivity. When aggregated with the MTZ-82 tractor, the energy indicators for the root crop harvester were obtained. Accordingly, speed of movement, traction resistance and traction power in the root crop harvester were ranged as 1.0-1.4 m/h, 4.10-4.35 kN, and 4.10-6.09 kVt, correspondingly. The traction resistance of the root crop harvester was 19-21% less than that of the serial digger.
