Description

The rotary mower crushers are known, incorporating a rotor with articulated scrim on it and their interacting with counter-rotating plate. This plastic is fixed on the wall of the open-bottom casing in which the rotor is located.

The knives due to their hinged attachment to the rotor in the process of work when meeting with particles of soil or shredded stems deviate from the radial direction of the rotor to the rotor. The knives in the deflected position can go up for several rotor turns, and they will not return to their initial radial position under the action of centrifugal forces. The deviation of knives from radnalno10 nozhodein leads, respectively, to their deviation from the opposing plastia and to an increase in the gap between inn. It disrupts the process of cutting.

In pre; 1, in the position of the mower for reduced; the deviations of the knives from the radial position in the places of the crenlein and the wedge are set to the external ones associated with this iozh and the heeling bracket.

FIG. 1 shows schematically a mower; on fng. 2 - the knot of the cutting of one of the knives.

The blades 5 and the breakaway mechanism 6, which has a crosspiece with elastic fingers 7. The knives 8 are mounted on the axes 9 n through H1TNFT 10 are fitted with springs // c 12 to the stop 13. The emphasis on the springs keeps the knives in the position where they are centrifugal pn rotate the rotor.

Works mower as follows. When the machine is moving, the veiled beam 4 tilts the plants on the course of a two-way link.

The dividers 5 guide the stems into the zone of action of the supra-laxating mechanisms, where the crosses strike the stem with elastic shovels and cause the ix to break.

height of 150-200 mm. In this place, it is usually less fragile, than at the bottom, where they are most often broken at a large slope. Tests of broken plants fall to the ground, and the nozzles at the height of the impact.

Thus, the stems occupy the optimum position, and the shredding knives cut them off and throw them to the countering elastin 3. At the same time, the stems are in weighted state, and the machine gradually runs over

for stubbled, the knives cut off particles of the stalks and throw them into the pipeline, where they are picked up by air and put into vehicles.

partially deviate from the radial position. Under the action of the moment from the centrifugal force, the knife tends to return to its original position. Spring 11 and 12 increase this moment and instantly return the knives. In this case, the zero will approach the stem of the shearing plate in a non-deflected position. The gap between the blades and the counterplate plate will be kept to a minimum, and the energy costs of cutting at the cutting edge are significantly reduced compared to the costs of known mowers.

Subject invention

A rotary cutter includes a rotor with blades hinged on it, characterized in that, in order to reduce the deviation of the knives from the radial position during operation, springs connected to the knife and the fastening bracket are installed in the places of the inclined knives of the knives.
