Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to mowing machines.

The purpose of the invention is to expand the technological capabilities of the mower on soils with strongly alternating microrelief, as well as to improve the shaping of the roll.

FIG. 1 shows a schematic diagram of the mower; in fig. 2 - front view mower; in fig. 3 - rezupdiy apparatus; in fig. 4 - cutting teeth.

L otokosilka consists of engine 1, gearbox 2 with axle 3, travel wheels 4, cutting unit 5 and control handle b rigidly connected to the drive unit 7 of the cutting unit 5. In case 7 there is a camshaft 8 connected to the drive 9 rotors 10 and through a bevel gear 11 with a cam split coupling 12 of the output shaft of the box 2 gears. The cutting unit 5 consists of a rotor 10 connected to the drive 9. The housing 7 rotates in the sleeve 13 relative to the gearbox 2.

To improve the formation of the roll, a roll forming plate 14 is installed above each rotor. In addition, to prevent the cut grass from being squeezed into the gap between the rotor and the windrow forming plate and to prevent the roller from being pulled, the cutting tooth 15 is provided.

Motookilka works as follows.

From engine 1, the rotation is transmitted through the gearbox 2 to the shaft 8 and the driving wheels 4. The rotation of the shaft 8 is transmitted by the actuator 9 to the cutting unit 5, the rotors 10. When moving forward, the grass is cut into the rotor space and placed in the roller. The rotors 10 are mounted so that their axes of rotation are at an angle to one another. The rotors are adjusted at angles a and p. Installing the rotors at an angle and eliminates the secondary cutting of the stubble, as well as touching the ground with knives when one or both of the wheels hit the mu ditch. Installing the rotors at an angle p prevents the rotors from touching the ground when the skis get into the furrow, ditch or when turning the body of the cutting unit.

The connection of the handle 6 control with the housing 7, if necessary, provides rotation of the cutting unit 5 around the horizontal axis of the mower.

When the rotors run over the bump, the torque on the axles of the wheels increases, as a result of which the cutting apparatus rises from the obstacle, after which it returns to the working position and continues the working process.
