Description

The invention relates to agricultural machinery and, more specifically, to machines for separating grape bushes from trellis openings.

The purpose of the invention is to reduce damage to the trellis wire and grape bush.

FIG. 1 shows the proposed device in the working position, side view; in fig. 2 - the same, in TpaHCijopT position, front view; FIG. 3 - frame displacement with rollers with non-uniform tension of wires on adjacent rows; in fig. 4 - the same, when the lateral displacement of the unit from the axis between the rows.

The device (Fig. 1) includes a carrier frame 1, hinged at one end on the transport carriage 2. At the opposite end of the frame on the lever trapezoidal linkage 3, the frame 4 is fixed with working elements 5 of roller type. The lower base of the trapezoidal hitch mechanism is smaller than the upper one. The working bodies are adjusted in height by hydraulic cylinders 6. In the transport position, the frame with the working bodies is fixed motionless with the help of a catcher 7 fixed to the frame of the vehicle.

In the working position, the magnitude of the swing frame with working bodies is limited to the stops 8.

The trellis wire 9 is fastened to the trellis posts 10 with the help of hooks 11. Grape bushes 12 are fixed on the wire (Fig. 1).

The device works as follows.

The aggregate moves in the direction of the slope of the sleeves of the vineyards 12. The unit with rollers 5 lowered and fixed with the help of the catcher 7 (Fig. 2) enters the aisle, towards which the hooks 11 on the trellis posts 10, supporting the trellis wire 9 are turned. the wire 9 is driven manually into the streams of rollers 5 by the workers who accompany the unit. At the same time, thanks to fixation, the frame with the rollers does not shift to the side when non-simultaneous charging of the roller wire from two adjacent

Row The frame 1 is raised by n-shrotsilindra 6 to the beginning of the separation of the wires from the bush 12, after which the unit begins to move between the rows,

gradually raise the frame 1 to maintain the tension of the trellis wires. In this case, the trellis wire is automatically removed from the hooks 11. In cases of uneven tension of the xpaler wires on rows, and stronger attachment of vines and sleeves on one of the rows, transverse vibrations of the aggregate on the unevenness of the soil and its lateral displacements, the frame with rollers confused in the direction of the row, where the tension of the trellis wire is greater (Figs. 3 and 4). At the same time, due to the fact that the lower base of the trapezoidal attachment mechanism is smaller than the upper one, the lowering of the rollers with more loaded wires also occurs. As a result of the tension of these wires weakens and decreases

Damage to the trellis. When you tension the wires on adjacent rows, the frame with the rollers self-adjusts to its original position, while the prototype, as indicated above, requires more force to return the rollers to its original position than to remove them from the equilibrium position. As a result, damage to the trellis is also reduced.

Due to the fixing of the rollers on the same frame, the vines are not bent around the downstream trellis wires during the process of their detachment from the bush, which reduces the amount of damage to the field.

The effect of the vertical oscillations of the aggregate on uneven soil is compensated for by the parts of the trellis wires released from the bush due to their sagging between the rollers and the root trellis pillar.

When a wire breaks on one of the rows during the passage of the assembly or earlier by other mechanisms, as well as on sparse landings, when the tension of the wires on two adjacent rows is most significant, the amount of displacement and the angle of rotation of the frame with working elements are limited by stops 8 As a result, the tension of the entire trellis wire was preserved. 302134

It is sufficient to separate the lump, which also reduces the 12, while the formation of a loop from the trellis damage in comparison with the trellis wire around the roller of the prototype.
