Abstract

1. A rotary mower, including a supporting beam, mowing rotors installed on it and a rotor drive mechanism located in it, characterized in that the mowing rotors installed in at least two tiers, located one above the other, have cutting elements (knives) placed at a distance of not less than 150 mm from each other vertically. 2. The rotary mower according to claim 1, characterized in that the cutting elements (knives) are located in their tiers on rotors pairwise rotating towards each other, and the knives of the rotors of the lower tier with the knives of the upper tier are mounted in mutually perpendicular planes symmetrically to each other relative to the axes of the rotors .

Description

to the application L 200IIG2387 / I3 (002 | W || ROTARY MOWER

The invention relates to agricultural machinery, in particular, to devices of cutting apparatus of a rotary type of harvesting machines.

A hay harvesting machine is known, including a rotor mounted on a frame, rake with fingers, fixed around the perimeter of the rotor, a swather, characterized in that in order to intensify the drying of hay by destroying the outer layer of stems, the swather is equipped with guides pivotally mounted on it with a variable ™ ofig5 the rake fingers are located between the guides, and the ugougrablin and guides are less than 90 °. The guides are made wavy on the side of the rotor and mounted in horizontal planes. The fingers of the rake have a section in the / - shape (I).

The disadvantage of this machine is that when the outer layer of stems is destroyed with the help of rakes and swath-forming devices, the leaves and inflorescences of plants are cut off and lost, and they are the most nutritious.

Known rotary single-bar mower KRN-E, 1A with a working width of 2.1 m, designed for mowing high-yielding grasses (more than 15 t / ha) at higher hepatic speed (9-15 km / h) and laying the mowed mass in swath (2) .

The mower consists of a main wound, an omnipotent articulated frame, a traction fuse, a bar of a cutting apparatus with four rotors, a field divider and a transmission system for driving the working bodies from the tractor power take-off shaft.

Each pair of rotors rotates in the opposite direction and during operation discards the stems in the form of two streams of beveled mass, leaving a swath behind the machine.

The rotors were mowed "and mounted on vertical axes and equipped with pivotally fixed knives that, when faced with an obstacle, can rotate freely in a horizontal plane.

The disadvantage of this mower is that it does not have a working body that allows intensifying the drying process of the mowed grass stand .. ,, 1:

The purpose of the invention is the intensification of drying of herbs during the harvesting of hay and haylage and the preservation of feed quality,

tori and the rotor drive mechanism located in it, and the chamfering rotors located one above the other and installed in at least two tiers have cutting elements (knives) located at a distance of at least 150 mm from each other vertically. The cutting elements (noida) are located in their tiers on rotors pairwise rotating towards each other, and the knives of the lower tier rotors with the knives of the upper tier are mounted in mutually perpendicular planes, symmetrically to each other relative to the axes of the rotors.

In FIG. I shows a diagram of a rotary mower; Fig. E view overrides Fig. 1.

The rotary mower contains a frame I with a drive mechanism 2, a beam 3 with upper 4 and lower 5 rotors with working elements in the form of knives b, mounted hinged, the shield of the field divider 7 .. Rotors 4, 5 are mounted on vertical axes 8, at least two tiers and one above the dfugim with a distance between the knives 6 of the upper rotors 4 and the lower 5 not less than 150 mm. The knives b are mounted on the rotors 4, 5 symmetrically to each other with respect to their axes, and the knives of the rotors 5 of the lower tier with the knives of the rotors 4 of the upper tier are installed in mutually perpendicular planes. Inside the beam 3 is a gear drive 9, which provides the opposite direction of rotation of the rotors 4, 5.

Rotary mowing machine works as follows. During operation, the torque from the tractor PTO through the drive 2 is transmitted to the rotors 4, 5 mounted on the vertical axes 8 on the beam 3. Sew with the rotors 4, 5 hinged knives b. When moving the cutting apparatus into the grass front, the knives b of the upper rotors 4 cut off the upper part of the plants at a height of at least 150 mm from the knives 6 of the lower rotors 5, and the knives b of the lower rotors 5 cut the lower 4acfb; plants at the height established by the initial requirements, b-C cm from the ground. The knives b cut the grass according to the principle of an unsupported cut, grab it and take it out of the cutting zone, moving it above the unsuccessful 3. The trajectories of the knives b of the adjacent rotors (upper 4 and lower 5) mutually overlap, which ensures high-quality sweeping. Mowed grass, having hit the flap of the field divider 7, changes the trajectory of motion, fits into the swath and makes room for the passage of the tractor wheels during the subsequent passage.
