CONSTRUCTIONS AND CINEMATIC MODE OF OPERATION CLEANER OF ROOT CROPS

Abstract

The results of research of structural features of devices are presented for the simultaneous cutting away of tops and cleaning of heads of root crops of sugar beets, certainly them positive sides and failings. On the basis of what the new is offered structurally technological the chart of purifier of heads of root crops from tailings of tops with the vertical axis of rotation in which is united technological operations of cutting away of tops and doochischennya tailings of tops, thus cleaning of heads of root crops after cutting away of bulk of tops from a working area conducted knives and taking away of it by a purifier with an elastic working at the printing-down of growth of head of root crop, that allows to attain high quality of cleaning at the minimum damages of body of root crop. The analysis of classical root clearing technologies and their collection, the effect of different schemes of purification devices on the purity of the head and the integrity of the body of the root, taking into account the energy consumption of the process, are carried out. The problem of improving existing and inventions of new constructions of machines for cleaning taking into account the physical and mechanical properties of root crops of contact cleaning, the quality of work satisfies agrotechnical requirements. The article proposes a new construction of a device for cutting the hinges and cleaning the sugar beet root crops heads, which combines two technological processes - cutting the hinges and subsequently finishing the surface of the head of the root with a hard surface of the disk and elastic whiskers, provided that the copy height of each root crop is copied. The proposed design of the device is made in the form of a drive shaft installed at an angle to the vertical, on which, with the possibility of axial displacement, a harness with a copying disc on which the knives and cleaning blades are installed is secured. Also, an analysis of the kinematic characteristics of the work of this cleaner is carried out and the kinematic mode of his work is substantiated. The result of the study is to determine the prospects for improving the technology of cleaning the honeycomb sugar beet, proposed a new design of a combined cleaning machine and substantiates the kinematic mode of the work of the cleaner.
