Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to reduce the loss of seeds from the weeping chamber. The tooth of the flax combing drum is made of different lengths and grouped. The first along the stems in the chamber, group 12 of each ridge 6 is assembled from shortened teeth, the second group 13 from elongated, one third from shortened teeth, etc. alternately. The latter group contains elongated teeth. The edge of the blade 8 of each crest, not located in the plane of the latter, is made in the form of a wave, while its depression coincides with the Action Zone of the shortened teeth, and the crest of the wave is elongated. Each consecutive tooth group on all ridges x 6 is located at the same distance from the input 9 of the drum disk. In operation, the ridges 6 and the blades 8 compact the product stripped in the chamber tray and give it a wavy surface consisting of edges and cavities. These ribs are compacted over time and are not destroyed by peeling stalks. Flax stalks slide along the ribs, but do not touch the bolls and seeds that are in the hollows. The stalks displace only the capsules, which appear for a short moment on the ribs, into the cavities, and from the cavities the boxes and seeds displaced from the ribs are removed by elongated teeth. 2 hp f-ly, 4 ill. 7 s (L m eo y F119.

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

The purpose of the invention is to reduce the loss of seeds from the weeping chamber.

FIG. 1 shows a diagram of a flax harvester, side view in section along a combing drum; Fig 2 - stripping drum, view, front; in fig. 3 - a crest, front viewJ in FIG. 4 - the same, top view.

Flax harvester contains a pulling machine 1 with a cross conveyor, clamping conveyor 2, camera 3 tow with combing drum 4; 5 pile conveyor and other working bodies. Stripping drum 4 includes ridges 6 with blades 7 5 located in the plane of ridge 6 and blades 8 set at an angle of 5 to it and also input 9 and output 10 disks and an eccentric mechanism 1 1 each - Ben 6. It consists of groups of 12 shortened teeth and. groups of 13 elongated teeth. The first group of teeth in the cadre crest 6 is made up of shortened teeth, and the last is made of elongated teeth. The blade 85 is set at an angle to the plane of each ridge, has an edge made in the form of a wave, while the depression 14 of the wave coincides with the zone of action of groups 12 .. assembled from shortened teeth, and the ridge 15 of it coincides with the zone of action of the elongated teeth.

Flax harvester works as follows.

The flax stalks, harvested by the top-lifting apparatus 1, are fed by the transverse conveyor to the clamping conveyor 2 and squeezed in it by stripping; ridge 6 of drum 4. Stalks without boxes are removed from the combing unit and spread out on the ground or bound into sheaves. The resulting heap is transferred by the ridges 6 and the blades 7 and 8 to the pile conveyor 5, which transports it to the cart attached to the combine.

During the operation of the combing drum 4, in the pan of the camera 3 of the flap there always remains a part of the products of the tow (mainly bolls and seeds), which are outside the range of the ridges 6 and the blades 8 that are not installed in

2 2

plane crests. This. Some products of the tow are not caught by the ridges and blades and do not change during operation, but as a result of the action of the elements and stems, they are compacted and the stem 1 does not move. The stalks glide over it, but part of the boxes that are in short

the moment is above this compacted layer.

Since each comb 6 of the combing unit consists of a group of teeth, the first group 12 along the stem in the chamber is made up of shortened teeth, the second group 13 is elongated short, the third 12 are shortened, etc. alternately, and the last group 13 contains elongated teeth, the layer of products O4ecaj remaining in the pan of chamber 3 has a wavy surface above, i.e. consists of ribs and hollows. These ribs over time are compacted and not

- destroying ots by stripped stems. The stalks glide along the edges, but do not touch the capsules and, found the sun in the hollows. The stems displace the capsules that appear for a short momeat (until the next ridge approaches) on the ribs, in the depressions, and from the depressions the boxes and seeds displaced from the ribs are removed with yAJiMHeHHbEviH teeth.

The ribs form naturally under the action of the ridges, they prevent the boxes from being removed from the chamber, but to a lesser extent they prevent the movement of the stems than if they were stiff. Therefore, there is no bending of the stems and damage by their teeth. If an increased weight of the stems enters the stripping apparatus, the fins collapse for a short time, but then they are formed again and contribute to the retention of the seeds in the chamber (reduce losses). By changing the position of the ridges by the exdeitric mechanism 11 (in the transition from short stem to long flax

The tooth sprout is shifted, and the ribbed surface of the stripped stalk supporting layer is simultaneously shifted

The ribbed surface equally prevents the removal of the -fullly from the chamber, both on the average length of flax stalks and

and on short and long stem flax.
