Abstract

The invention relates to the field of agricultural engineering. The purpose of the invention is to reduce the loss of seeds carried by the lower surface of the ribbon of stems. The unit contains the lifting gear 1 and the clamping conveyor 2. The skiving reel 4 has ridges 5. The device also contains a chamber 6 towels (CO), conveyors 7 and 8, a spreading device and a trailer 10. The blades II and 12 ridges are made with longitudinal grooves. Under the drum 4 in KO 6 there is an arcuate vibrating grid 13, which is fixed in the lower part on the axial hinge. In the upper part, the lattice 13 is connected to the shaft of the drum 4 by a crank mechanism located on the side of the CO 6. When moving through the CO 6, the seed boxes are peeled off with ridges 5. The resulting pile is subjected to intense separation by the simultaneous simultaneous action of blades II and 12 and the arc-shaped gratings 13. The tangle is thrown by the blades II and 12 onto the conveyor 7 of the tangle.

The invention relates to cej.DKOXO3HflcT-vennom mechanical engineering, in particular to machines for harvesting flax.

The aim of the invention is to reduce the loss of seeds brought out by the lower surface of the ribbon of stems.

FIG. 1 shows a flax harvester, side view; in fig. 2 - the same, front view; in fig. 3 - lobes of ridges with longitudinal grooves.

The flax harvester contains a lifting machine 1, a clamping conveyor 2 mounted on shaft 3, a stripping drum 4 with ridges 5, placed in a 6-haul chamber, conveyors of confusion 7 and otdeltarii mass 8, a spreader 9 and a trailer 10 for collecting separators - weight and confusion.

Each ridge 5 has two blades with longitudinal grooves. One blade 11 is located in the plane of the ridge 5, and the other blade 12 is at an angle to the ridge 5. The unit also has an arcuate vibrating grid 13 placed in the 6-haul box under the drum 4. At the bottom, the lattice is mounted on a fixed hinge 14, and the upper unit is connected to the shaft 3 of the drum 4 by a crank mechanism located on the sides of the 6-wing chamber; the lower part of which is adjacent to the conveyor B of the separated mass, for example, consisting of the fan 15 and the blower legs of the duct.

The crank mechanism has a crank 16 fixed on the shaft 3 of the drum 4 and pivotally connected by a connecting rod 17 to an axis 18 connected to the grille 13.

The connecting rod 17 has a screw pair to change its length.

The trailer 10 has a rotating wall 19 dividing the total capacity into two - for the separate collection of confusion and separated mass. A retainer 20 is provided for fixing the wall 19.

On the shaft 3 of the drum 4 is installed the sprocket 21.

Flax harvesting unit operates as follows.

The flax stalks from the top-lifting unit 1 come in the form of a continuous tape into the clamping conveyor 2, with which it is channeled through the 6-haul chamber. When moving through the chamber 6 towels from the stems of the ridges 5 of the drum 4, which receives rotation through the drive sprocket 21,

seed pods. The resulting heap undergoes intensive separation by simultaneous simultaneous action

stBi blades II and 12 and an arcuate brush 13. The tangle (fragments of stems and weeds) is thrown by the blades 11 and 12 onto the tangle conveyor 7, which is diverted into a container to collect tangle in the trailer 10.

The separated mass (a mixture of whole and destroyed seed pods, free seeds and weeds) through the grooves of the blades 11 and 12 and the arcuate vibrating grid 13 spills into the lower part of the chamber 6 inches, to which the conveyor 8 of the separated mass adjoins and under the action of the air flow created by fan 15, is transported along the injection duct to the second part of the trailer 10. The stripped ribbon of the stems is drawn onto the spreading device 9 by the clamping conveyor 2 and spread out across the field.

The vibration of the arcuate lattice 13 is carried out near a fixed hinge 14. The oscillation amplitude is varied, for example, by setting the drum 3 on the shaft 4 of the cranks 16 with varying eccentricities.

The setting of the optimal gap between the arcuate grid 13 and the ends of the ridges 5 is carried out by changing the length of the connecting rods 17 having a screw pair.

Trailer 10 first unloads the pantoin and then the separated weight.
