Description

The invention relates to agricultural machinery and can be used in rotary mowers when mowing natural and seeded herbs and accelerate their drying.

Known rotary mower with aerator [1], containing rotors with vertical axes of rotation, cutting elements and plates of a straight shape mounted on the outer surface of the drums. On the outer rotors of the mower there are drums with beater made of angle steel located longitudinally on their surface, and on the middle rotors there are drums-aerators, which are removable hollow truncated cones with covers in the upper part, rigidly fixed with bases to the rotors, and the drums - aerators are equipped curvilinear plates rigidly mounted on their outer surface obliquely at an acute angle with respect to the direction and plane of rotation of the rotors with aeration drums, the outer edges of which have a variable radius decreasing in the direction of their rotation and not exceeding the radius of the cutting edge formed by the ends of the flail blades rotors.

Aerator drums and drums with beaters are equipped with removable covers, which are fastened with screws on top to an annular flange made inside the drums and provided with holes for self-tapping screws and radius recesses located under the mounting bolts of the drum bases, with an offset of 45 ° relative to the holes for the screws.

The disadvantage of this mower is the inability to ensure injury to the stems of plants and damage to their cuticles.

Known rotary mower with a device for injuring plants [2], containing a cutting apparatus with rotating disks with hinged knives and removable drums vertically mounted on them in the form of truncated cones. The drums, made of the same size, are mounted on pairwise rotating disks, alternating each other, the first drum on the right in the direction of movement of the mower is equipped with beaters longitudinally rigidly mounted on its surface symmetrically to each other, the lower part of which is bent, the next one with L-shaped beats, made of circular steel, containing impact rods, lintels and stops, located diametrically opposite perpendicular to the blade knives and attached to the side surface of the upper part of the drum for pivotally jumper radiused protrusions clamps made from a steel strip, shock rods, wherein in each such beat the drum may be mounted horizontally in the same plane or different, and each pressing lug Radius provides shock deflection rods at an angle of 90 °.

The disadvantage of this mower is that the beater drums do not very efficiently feed the beveled mass into the treatment zone with the beaters, while a high degree of trauma to the plant stems is not provided and high field losses are observed.

The purpose of the invention is to improve the supply of beveled mass to the treatment zone with bills, to ensure high-quality injury to plant stems, and to reduce field losses.

This goal is achieved by the fact that the mower with an air conditioner of the beater-screw type contains a cutting apparatus with pairwise rotating disks with hinged knives and vertically mounted on them alternating with the same height drums in the form of truncated cones, one of which is equipped with hinged Г- in the upper part shaped beams located horizontally, diametrically opposite, in the same plane or different. Other drums are equipped with screws of the right direction of rotation, consisting of curvilinear plates rigidly mounted on their outer surface obliquely at an acute angle with respect to the direction and plane of rotation, the outer edges of which have a variable radius, decreasing in the direction of their rotation and not exceeding the radius of the cutting edge formed by the ends of the hinged knives of the disks, and all the drums are fixed, and their alternation is carried out from right to left along the mower, from a drum equipped with with g-shaped beaters parallel to the blade knives.

In FIG. 1 shows a side view of a windrower-type mower with an air conditioner; in FIG. 2 the same top view; in FIG. 3 is a side view of a drum with beat bars installed in the same plane; in FIG. 4 the same, but in different planes.

The air-conditioned mower of the beater-screw type comprises a supporting beam 1 with disks 2 rotating towards each other with knives 3 pivotally mounted on them and fixedly fixed vertically on the disks 2 by fixed drums 4, 5 in the form of truncated cones. All drums 4, 5 are made equal in height and are located on pairwise rotating disks 2 alternating each other. The first drum 4 on the right in the direction of movement of the mower is equipped in the upper part with hinged L-shaped bits made of round steel containing shock rods 6, lintels 7 and stops 8. L-shaped bits in the upper part of the drums 4 are diametrically opposed to their vertical axes parallel to the knives 3 of the disks 2 and pivotally attached with radial protrusions of the bandages 9 for the jumpers 7 to the side surface of the upper part of the truncated drums 4. The stops 8 L-shaped beats are designed to exclude the possibility of their popping Bani of curved protrusions bandages rods 9. Drums 6 beat on each reel 4 can be mounted horizontally in the same plane or different. Following the drum 4, the drum 5 is equipped with a screw of the right direction of rotation, consisting of plates 10, 11 of curved shape, rigidly mounted on its outer surface obliquely at an acute angle with respect to the direction and plane of rotation. The outer edges of the plates 10, 11 have a variable radius, decreasing in the direction of their rotation and not exceeding the radius of the cutting edge formed by the ends of the hinge knives 3 of the disks 2.

A mower with air conditioner screw type works as follows. When a tractor with a mower moves across the field, the torque from the tractor PTO is transmitted to the disks 2 located on the supporting beam 1 with knives 3 pivotally mounted on them and rigidly mounted on the disks 2, one after the other, vertically from right to left along the mower, with drums of the same height 4, 5 in the form of truncated cones, equipped with different working bodies.

For the implementation of the conditioning process, the L-shaped beats are pivotally mounted in the upper part of the drums 4 by means of the radial protrusions of the bandages 9 diametrically opposite, parallel to the knives 3 of the disks 2, horizontally in the same plane or different. The radial protrusions of the bandages 9 provide a deviation of the articulated beat when interacting with obstacles, for example, stones while mowing grass at an angle of up to 90 °. Stops 8 do not allow the beaters to jump out of the radial protrusions of the bandages 9.

Following the reels 4, the reels 5 are equipped with screws of the right direction of rotation and consist of plates 10 and 11 of a curved shape, rigidly fixed to their outer surface obliquely at an acute angle with respect to the direction and plane of rotation. The outer edges of the plates 10, 11 have a variable radius, decreasing in the direction of their rotation and not exceeding the radius of the cutting edge formed by the ends of the hinge knives 3 and disks 2.

When moving the mower into the grass, the hinge knives 3 of the disks 2 pairwise rotating towards each other with the drums 4, 5 with articulated L-shaped bills and screws of the right direction of rotation cut the grass. The screws of the drums 5 feed grass into the treatment zone with L-shaped beams pivotally mounted on the drums 4. L-shaped beams with rods 6 hit the stems of the plants, injure them, crush them, partially crush them, remove them from the treatment area and put them into well-aerated rolls ( swaths).

The use in the design of a rotary mower of drums with hinged L-shaped chisels and screws of the right direction of rotation, working in pairs and rigidly mounted vertically from right to left along the mower disks on the mower disks, improves trauma to plant stems during mowing grass, improves feed mowed mass in the processing zone by bills, reducing field losses.
