Justification of parameters of vehicles with elastic partitions for transporting potatoes

Abstract

Elastic partitions have been developed to be installed in the body of a vehicle and allowing to reduce damage to tubers when unloading by reducing the speed and, accordingly, the interaction of potatoes with the working surfaces of the machine and neighboring tubers. A mathematical model of a device for transporting and unloading root crops has been developed, taking into account the physical properties of root crops, the physical and geometric characteristics of the container and elastic partitions, as well as the parameters of the unloading process. As a result of comparative field tests of a serial MAZ 5516 truck body and an experimental MAZ 5516 truck body with installed transverse partitions, it was found that the use of the developed elastic transverse partitions reduces damage to potato tubers from 5.3% to 2.9%.
