Description

one

The invention relates to agricultural machinery and can be used for mowing and plush grasses.

Rotational mowers are known with vertically arranged several pairs of roller rollers, the cylinders of which lie in one plane perpendicular to the direction of movement of the machine.

However, in such plush mowers, each pair of nlyush, zhilny rollers forms a separately located mass roll, as a result of which the rolls are kneaded by the machine wheels due to their frequent location on the floor.

The goal of isoblency is to form an enlarged roll from several pairs of plush rollers.

This is achieved by the fact that the rollers are installed at the node angle to each other and to the horizontal plane.

FIG. 1 shows a schematic representation of the proposed mower conditioner, top view and view along arrow L; in fig. 2 is a cross-section of the resulting roll.

We offer a mower-plushilka has several pairs, for example, three, plushnyh rollers located behind the cutting unit / rotary type. The cylinder axles of the middle rollers 2 are laid vertically,

and the axes of the crown and the left pair of rollers 3, so that the vertical planes, the passage of ours through these axes form with the vertical plane, passing through the axes of the cylinders of the middle rollers, the dihedral angle a. In addition, the axes of the cylinders of the outermost pairs of rollers are inclined in vertical planes at an angle p to the horizontal plane. Extreme pairs of rollers are equipped with guides 4 to 5.

Mower-conditioner works as follows. The stems cut by the rotary cutter / are captured by the flattening rollers 2 and 3 and, flattened out under their pressure, form streams of flattened mass, which, reaching the mowed surface, form an enlarged mass roll from several pairs of rollers. The flow of rolled mass formed by a pair of rollers moves in a plane tangential to the cylindrical surfaces of the rollers and passing through the line of their contact. The flows from the right and left pairs of rollers, due to the inclination of their axes to the vertical plane passing through the axes of the cylinders of the middle pair of rollers, are directed to the middle of the swath. The flow of swaged mass coming out of the middle pair of rollers reaches the sloping surface and forms the average roll. Mass flows from extreme

The nap rollers, due to their inclination and the corresponding shape of the guiding guards, form the right and left components of the enlarged roll, the stems in which are located advantageously in the longitudinal direction. To prevent the collision of mass flows and their subsequent mixing, as a result, a swath with an arbitrary arrangement of stems is formed, the lengths of the guide plates are different.

The subject is invented and

A mower conditioner comprising a rotary cutter and several pairs of flattening rollers, characterized in that, in order to form an enlarged roll from several pairs of flattening rollers, the latter are set at an angle to one another and to the horizontal plane.
