Description

The invention relates to the agricultural machinery industry, in particular to the working bodies for the meanized removal of the winery.

The purpose of the invention is to increase the flexibility of the combs.

FIG. 1 shows a shaker of a grape harvesting machine, a xonometric in FIG. 2 - the turning shaft, section is represented; in fig. 3 is a schematic diagram of a shake-up in an area free of trellis supports, top viewJ in FIG. 4 is a schematic diagram of a shaker when interacting with a trellis support, top view.

Build The grave harvesting machine consists of. the left 1 and right 2 sections, interconnected by transverse beams 3 and forming its frame- which, by means of the uprights 4, are hinged on the frame 5 of the harvesting machine.

The sections of the frame are set to the direction of ush; s 6, made in the form of frames with bent front ends, and eccentrics 7, each of which by means of levers 8 and 9 and ti g 10 of variable length are kinematically connected with a probe 11, and also stops 12 and springs-13, which press the eccentrics 7 against the stop 12, and 1 1 against the center of the agitator.

On the eccentrics 7 (Fig. 2) rotary shafts 14 with finger combs 15 are placed. The shafts 14 by means of levers 16 and connecting rods 17 of variable length are connected with cranks 18 and 19, which provide oscillatory movement of the combs.

Built-in grabber harvester works as follows. During operation of the stirrer, the crank 18 and -19 are driven into rotational motion with an angular velocity tJ, and the shafts 14 associated with them by the combs 15 perform an oscillatory motion around the axes of the eccentrics 7, which ensures separation of the crop from the vegetative mass of the bush.

During operation of the agitator in the zone free from supports (Fig. 3), the comb 15 makes an oscillatory movement around the axes 0 with an amplitude of 5 amps relative to their neutral position. O S

Pitch centering Sustainable operation of the agitator, i.e. maintaining a constant gap S between the combs, is ensured by tensioning the springs 13, which press the eccentrics 7 to the stops 12 and establish the eccentric axes perpendicular to the longitudinal axis of the agitator. When one of the pairs of probes 11 (for example, the front one) comes into contact with the support 20 (FIG. 4), the probes kinematically connected with the eccentrics 7, overcoming the tension of the springs 13, turn the eccentrics of this pair around the axis O and move the shafts 14 with the combs 15 of O, s, polo

the ends of the dies increase by the thickness of the support; the oscillation of the dies occurs with the same amplitude A, but in a different plane relative to their original position. The fingers of the comb, actively acting on the bush, do not directly affect the support in connection with the increase in the gap between the ends of the combs on the thickness of the latter. In this case, the second pair of combs work. Net in the original mode.

After passing the support, all the fingers of the combs work in the original mode.

The pro-displacement of the support 20 or machine relative to the axis of the row, the guides 6 orient the inserter relative to the support without additional loads on the combs.
