SU494147A1 - Sheet-orienting site tobacco-harvesting machine - Google Patents

Description

In the process, the drums shrink a layer of trapped leaves into a plane lying in the adjacent zone of the augers. The optimal layer of the captured leaves is somewhat larger than the sum of the outer half-diameters of both screws, for example, with a screw diameter of 80 mm, the layer will be about 100-120 mm.

The captured leaves, as they turn perpendicularly to the movement of the machine, are intercepted all the time in separate areas and are not damaged. Rollers 3 and 4 ensure the creation of an interval between the sheet-oriented drums and the leaf-separating body 7. This interval and flow rate and the gap between the adjacent rollers are necessary for a smooth reversal of counter-growing leaves. In addition, the rollers feed the already oriented leaves to the leaf-separating organ, and the angled front rollers perform part of the functions of the leaf-expanding rollers, in particular when the opposite-growing leaves are oriented.

Claims (2)

1. An orientation node of a tobacco-harvesting machine containing installed one above the other counter-rotating drums with an elastic surface, characterized in that, in order to improve the efficiency of leaf orientation perpendicular to the movement of the machine, the drums are installed at an acute angle to the direction of motion, and their elastic surfaces are made in the form of multiple-feed screws with different angles of lift and directions of helix lines. 2. A node according to claim 1, characterized in that behind the drums there are two pairs of opposing rollers with elastic surfaces forming a slot extending to the stick of tobacco bushes, the axes of rotation of the first pair are set under the sharp, and the second is directly under angle to the direction of movement of the machine.
