SU235459A1 - ADAPTATION TO TOBACCO BAGGING MACHINES FOR LEAVING ORIENTATION BEFORE THE BRANCH - Google Patents

Description

Accessories for tobacco-harvesting machines for the orientation of the leaves before separating them1 from the stem, made in oppositely rotating rollers mounted one above the other with an elastic surface are known. When moving the machine, the elastic drums, rotating, pinch the tobacco leaves before they are separated from the stem, put them in a certain position. The machine is equipped with a leaf separating device, the installation of which is made difficult by the proximity of the alignment rollers to the plant stems.

In the proposed arrangement with the use of orienting rollers to separate the leaves without additional leaf compartment of the equipment, the top of the rollers is mounted on a rotating leash, periodically bringing it to the lower roller and rolling it over it In the working area.

To increase the rolling arc of the upper drum, on the lower leash, there is made of two hinged-connected parts, the total length of which is more than the distance from the center of the drum to the axis of rotation of the leash. In addition, a small rotation of the leash is provided with a disk for the friction drive of the lower ring. Such a structure allows the production of the top: in the leaves from the stems at the moment when the base of the leaf is between the rolls.

FIG. shows the described prisoosplenpe, top view; on phpg. 2 - the same, vnd front; in fig. 3 - various positions of Ba.1tsov in the process of orientation and detachment. The device for orientation of the leaves contains rolls placed one on top of each other from a row of plants and one above the other with an elastic surface. The drum / is driven n rotates from

The disk 3, which, in turn, is driven into rotation from the V-belt transmission 4. On the shaft 5 of the disk 3 is worn a driver 6, Hbiii is made of two pivotally connected parts, near which the freely rotating

drum 2.

When moving the machine along the pitch, the tobacco stalks with dividers 7 and S are directed to the orienting rollers. In this case, the drum / rotates continuously, and the drum 2, which rotates together with the driver 6 around the shaft of the disk 3, periodically approaches the drum 1 and rolls around it due to the forces of friction arising between the rollers of their contact. At this moment there is a clamping of the leaves and their orientation. In order for the rollers to be clamped until the leaves are taken off, the driver has a total length exceeding the distance from the center of roller 2 to the axis of rotation 9 of the driver, and attached to the valve after contacting the shaft / l 2 after further removal of the driver 6 oiH, overcoming the resistance of the springs 10 , in the place of the hinge istibatsya, choose a gap in the eyes of the links. FIG. 3, the moment of the greatest bending is shown: the leash, when the distance between the valleys of the surface and the axis of rotation 9 through: the vodka is the smallest. After that, under the spring, the flood takes on its original position, i.e., it is rectified. The torn leaves during the rolling in of the roller 2 around the roller / fall onto the conveying device and are transferred to the bunker. The subject matter of the invention 1. The adaptation to the tobacco-harvesting machines for the orientation of the leaves is lered by separating them from the stem, made in the form of mounted counter-rotating rollers with each other with an elastic surface, characterized in that, in order to use the rollers and to separate the leaves, the upper one is fixed on a rotating leash, periodically moving it to the lower drum and rolling over it in the working area. 2. The tool according to claim 1, characterized in that the leash is made of two articulated parts, 0 | general length of which is longer than the distance from the center of the drum to the axis of rotation, the lead 3. 1, characterized in that a disk for friction drive of the lower drum is located on the axis of rotation of the leash.
