SU1253477A1 - Divider for flax-pulling machine - Google Patents

Description

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

The purpose of the invention is to increase the productivity and quality of work during the harvesting of laid and low stem flax.

FIG. 1 is a side view of a flax harvester; in fig. 2 - the same, top view; in fig. 3 - the scheme of the divider in meeting with an obstacle.

The flax harvester divider contains a central 1 and side 2 rods rigidly mounted on the support bar 3, to which a three-link mechanism with A-6 links is attached to the bottom through hinges. The front link 4 is directed downwards and in the initial position is matched with the central rod, which is a continuation of it. The lower link 5 and the rear 6 are interconnected by a hinge 7, which is provided with a cam 8 as a polo, and an adjustable stop 9 is installed on the back link. In the initial position, the spring 10 locks the link 6 to the stop 9 and fixes the mutual position of the three-link links. The divider in its upper part is fixed on the machine on the rotary axles 11 side rods, and in the lower part by means of a telescopic joint 2 at the base of the support bar. A telescopic stroke has a one-sided restriction due to the installation of an adjustable stop 13.

Divider flax harvester works as follows.

To clean the laid and low stem flax, the divider together with the machine-lifting part is lowered until the copier 8 contacts the soil surface and the adjustable stop 9 is moved to the position where the nose of the link 4 touches the floor. Adjustable stop 13 move to the right

on the magnitude of its full stroke, minimizing the limitation in the telescopic connection 12. When moving the flax harvester along the field, the divider separates with link 4 and

bar 1 flax stalks into strips, and side rods 2 brings them to the mouth of the pulling stream. If, when encountering an obstacle, link A acts greater than the response given by spring 10, the spring expands, links 5 and 6 begin to fold, and hinge 7 with cam 8, lower, raises the divider until the link 4 not

rises above the obstacle, copying it. When this happens, the splitter rotates on the trunnions 11. After the obstacle is bypassed, the divider link 4-6 is returned to its original position by the action of a spring. Thus, the floor surface is copied and the divider is protected from damage. Povysheny performance when cleaning the lodged and low stem

flax Achieves higher machine speeds without fear of damage,

To clean the normal flax of normal length, the divider rises above the floor along with

using a trough to the required height and with the help of an adjustable stop 13, the support bar 3 is set to the horizontal position. The separation and supply of the stems is carried out in the usual manner.

The speed of movement of the harvester when harvesting ground flax is 10-12 km / h, and when harvesting laid flax is 4-6 km / h.

Claims (2)

1. DIVIDER OF THE FLAX-HARVESTING MACHINE, comprising a support beam, central and lateral with pins for turning the rods, rigidly fixed to the support beam, which is ensured by the fact that, due to the productivity of the work when harvesting flat and low-stem flax, on the support beam ^1, a three-link mechanism is pivotally mounted from the bottom, one of the links of which is located at an angle to the horizontal plane and is connected to the support beam at the place of attachment of the central rod to it, and the hinge between the other two links is equipped with a copier and is spring-loaded to the support Mu beam. 2, The divider according to claim 1, characterized in that on one of the links of the three-link mechanism there is an adjustable stop in contact with the support beam.
