Description

(5) TRUNKING COMBINE

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to machines for flax harvesting.

The flax harvester is known, containing a topping device, a transverse and clamping conveyor, a camera with a combing drum, on the shaft of which discs and ridges are mounted l.

The closest technical solution is a flax harvester containing a topping device, a transverse and clamping conveyor, a camera with a combing drum, on. the shaft of which is fitted with combs and disks, one of which has a ring with teeth,

The main disadvantage of these flax harvesters is that they have significant losses of seeds. The main part of the loss of seeds in the work is observed from the cam of the bat with a ribbon of battered stems. Seeds and boxes, located on the upper side of the tape, do not spill through the tape and do not fall into the slots of the shield located between the outlet part of the weep chamber and the spreading board, but are lost to the ground. In addition, trapping seed losses through cuts through a tray into a drawer or bag requires machine stops and time to empty the drawer or bag,

to

In order for the loss of seeds to be as small as possible, the window between the side of the chamber of the tow and the flap, which serves to exit the stems from the chamber, is done as much as possible.

Claims (2)

IS to prevent the stems from falling between the side and the drum disk and winding them onto the drum shaft, folding the side wall and closing the disk with the flanging. However, when harvesting high-yielding and laid flax, the peeled stalks do not fit in a narrow window, being delayed between its stationary generators, clog the window, i.e., e. reduce the technological reliability of the combine. The purpose of the invention is to reduce seed losses and increase the reliability of operation of the combine. This is achieved by the fact that the ring with the teeth is mounted on a disk located on the outlet side of the stems from the chamber. FIG. 1 shows the stripping drum of a flax harvester in a section perpendicular to its axis of rotation; in fig. 2 - the same view: front. A stripping drum of a flax harvester contains a shaft 1, discs 2, an eccentric mechanism 3, ridges k with blades, a ring 5 with teeth 6 fixed on the output disk 2. The baton consists of obeychayka 7, side walls 8 and rear wall 9. A flap 10 is fastened on the side of the stems coming out of the stem cell, supporting the apical part of the stems leaving the flake out of the stem cell. Above the shield 10 -I there is a grid of 11 rods and a fence 12. The fence 12 is adjacent to the ring 5 with its inner side. When the flax harvester operates, the combs k tear off the boxes from the stems moved by the clamping conveyor 13 Nozzle products are transferred by the ridges k and then their blades onto the pile conveyor I. In the process of transferring the pile through the drum t part of the boxes and seeds gets on the tape and is brushed off with teeth 6 attached to ring 5-. the apex part of the stems, the speed of the teeth of the ridges 4 in the plane of the tape decreases, therefore in this region the speed of the teeth 6 is greater; what is the speed of the teeth of the ridges A. Due to the speed difference, the stems are cut by the teeth 6. In this case, the boxes and seeds fall out of the tape on the shield 10. Because the tooth 6 discards the stems when they leave the chamber, and for the fact that the output shield. 10 is made convex upward, the stems moving out of the chamber as a fan moves. By fan-shaped movement, the ribbon is stretched and the stems move relative to each other, so that the bolls and seeds that are not caught by the teeth 6 wake up through the ribbon onto the shield and flow down it back into the feathering chamber, where they are carried by ridges and blades. they are given along with the whole pile to the conveyor 14. Lattice 11 does not allow the stems to touch the shield 10, therefore they do not prevent the boxes and seeds from flowing along the inclined surface of the shield. The ring 5 and the tooth 6 force the stems out of the chamber, therefore no clogging occurs at the exit of the stems from the chamber. The use of a ring with teeth on the output disk of the drum will reduce the loss of seeds with a ribbon of combed stems and increase the reliability of operation. You combine by eliminating the loading of flax at the exit of the baton. Claims of the invention: A flax harvester comprising a lifting machine, a transverse and clamping conveyor, a camera with a combing drum, on the shaft of which crests and discs are mounted, one of which has a ring with teeth, characterized in that, in order to reduce seed losses and increase reliability of operation of the combine; a ring with teeth is installed on a disk located on the side of the exit of the stems from the chamber.
