Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to mowers that cut and trim mowed vegetation.

The purpose of the invention is to improve the quality of flattening, the uniformity of the structure of adjacent rolls and simplify the design.

Figure 1 shows the mower-conditioner, top view; figure 2 - section aa in Fig, 1; Fig. 3 shows a sidewall with a two-unit conditioner.

The wide mower conditioner consists of two sections hinged frontally on the power means: left and right with rotary cutting units 1 and 2, respectively, frame 3 and two screws 4 and 5 with multi-directional turns. The screws end with firewood 6 and 7. The side frames of the frame are attached to the crimping blocks 8 and 9, in various cases having different organs: one pair of rollers 10, two pairs of rollers 10 and 11, rollers 10 and a flaillation machine installed instead of rollers 11 ( not shown). The frame 3 is mounted on the support wheels 12 and the coupler 13 is attached to the tractor.

The working bodies are driven through a central gear 14, mounted between the inner sidewalls. From the gearbox, the rotation is transmitted to the rotary modules (rotors) through the transfer box 15 and the portal gearboxes 16 and 17, and from there to the rotors of the device for the clearance of the gap between the sidewalls.

Drum dividers 18 are installed on the central rotors of the device for swath clearance between the sidewalls of the sections.

Each flatting machine is driven by separate cardan gears 19 and 20. To simplify the construction, the axis of the rotors of the cutting units and the device for passing the gap between the sections are located on the same straight line.

In operation, the mower conditioner mows the mass with rotary modules 1 and 2. The oblique mass is divided into two parts by rotors with dividers 18 and the screws 4 and 5 are moved to the side windows, which are thrown with firewood 6 and 7, and then processed by flatting machines.

Placing the gearbox between the internal sidewalls reduces the overall dimensions of the unit, which improves the copying of the relief.

The implementation of a device for swathing the gap between the central sidewalls in the form of two rotors of opposite rotation allows the mass to be evenly distributed over the sections, which ensures that the adjacent rolls are identical in mass and structure.
