Description

FIELD OF THE INVENTION The invention relates to agricultural machinery and can be used in a tobacco harvester.

The purpose of the invention is to reduce the loss of leaves without reducing their quality.

FIG. 1 shows the conveying device of the tobacco-harvesting machine, general view; in fig. 2 s.chema installation needle; in fig. 3 - leaf unloading section.

The transporting device of the tobacco-picking machine includes: 1 a nolovochny cloth 1, which contacts it with a second-time push-pull 2 roller 3, has an elastic surface. The press roller 3 is made of several 4 disks 5 arranged on one axis and placed with a gap relative to each other.

On the wire cloth 1, the needles 6 are installed, located opposite the gaps of the press roller 3. In the zone of leaves unloading inside the space between the wire cloths, a precise drum 7 is mounted, which has a drive mechanism (not shown). Needles 6 have a curvilinear shape with a radius of curvature of nik.poidy, forming

D TRANSPORTING DEVICE OF A TOBACCO CLEANING MACHINE, comprising a wire web in contact with a spring-loaded press roller having elastic surfaces, and a web drive mechanism, characterized in that, in order to reduce leaf loss without reducing their quality, the press roller is made up of disks located on the same axis forks placed with a gap one relative to the other, and on the wire sheet there are needles located opposite the gaps of the press roller, while in the zone of leaf extraction inside the space between blades mounted brush drum having a drive mechanism. 2. The device according to p. 1, characterized in that the needles have a curved shape with a radius of curvature equal to the radius of curvature of the cycloid formed by a circle point with a diameter equal to the outer diameter of the press roller. 3. The device according to πp. 1 and 2. characterized in that. that the needles are tilted by the tip towards the direction of the working movement of the web. 4. The device according to π. 1, characterized by re.a. that the brush drum is placed with the bristle part protruding outward from the wire web whose height exceeds the height of the needles. moreover, the angular velocity of rotation of the brush drum is equal to the angular velocity of rotation of the drive shaft of the wire web.
