THE ESTIMATION OF CONSTRUCTION AND PARAMETERS FOR CAREFUL LOADING OF CABBAGE HEADS BY MACHINE-HARVESTING

Abstract

When cabbage is traditionally machine-cleaned, its heads are mechanically damaged to a considerable extent, which reduces their shelf life during storage. The bulk of the damage is attributed to the processes of shipment of the heads to the body of the vehicle in bulk and unloading it when laying cabbage for storage in the coats. In existing designs and well-known works, no practical solutions were found, which could be realized with maximum efficiency in harvesting cabbage. In this regard, the aim of the study is to substantiate the design and basic parameters of the device for the careful shipment of cabbage heads during machine harvesting. For this purpose, a new method for machine harvesting cabbage is proposed (patent RF 2554403), where, unlike the traditional method, the head is first shipped in a sparing mode on a flexible trough-shaped flooring installed on a special rack above the detachable containers in the body of the accompanying vehicle. Then the heads from the flooring are gently transferred to containers for subsequent storage in them. The efficiency of the use of the proposed device and the degree of reduction of head damage in the process of shipment depends on its design and correct justification of the parameters. The nature of the flow of the process of shipment of heads is essentially dependent on the type of sagging curve of the trough-like form of the flooring. For the purpose of substantiating the design and parameters of the device for careful shipment of cabbage heads during machine cleaning, a mathematical model of the construction is proposed, using which the necessary parameters of the proposed device are determined.
