L-shaped beaters in upper part of drums 5 are located diametrically opposite to their vertical axes, perpendicular to knives 3 of disks 2 and are pivotally attached by radial projections of bands 11 behind webs 9 to side surface of top part of truncated drums 5. Stops of 10 L-shaped beaters are designed to exclude possibility of their jump-out from radial projections of bands 11. Impact rods 8 of beaters on each drum 5 can be installed horizontally in one plane or different.EFFECT: invention makes it possible to improve feed of chamfered mass to the zone of beating treatment, to increase quality of injuries of plant stems and to reduce field losses.1 cl, 2 dwg

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 extreme rotors of the mower, drums with angle steel beaters are installed, located longitudinally on their surface, and on the middle rotors 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, and 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 a wind-auger conditioner contains a cutting apparatus with pairwise rotating discs with hinged knives and vertically mounted on them alternating with the same height drums in the form of truncated cones, some of which are equipped in the upper part with articulated L-shaped bills located horizontally in the same plane or different diametrically opposite, perpendicular to the knives of the disks. Other drums are equipped with screws of the left 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 that decreases in the direction of their rotation and does not exceed 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 in the direction of movement of the mower, from a drum equipped with a screw com of the left direction of rotation.

In FIG. 1 shows a side view of a mower with a bilobo screw conditioner; in FIG. 2 same top view.

The mower with bilnik-screw conditioner contains a supporting beam 1 with disks 2 rotating towards each other with knives 3 pivotally mounted on them and fixedly mounted vertically on disks 2 with removable drums 4, 5 in the form of truncated cones. All the drums 4, 5 are made the same in height and are rigidly fixed (welded) to the pairwise rotating disks 2 alternating each other. The first drum 4 on the right in the direction of travel of the mower is equipped with a screw of the left direction of rotation, consisting of plates 6, 7 of a 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 6, 7 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. The next drum 5 in the upper part is equipped with hinged L-shaped bits made of round steel containing shock rods 8, jumpers 9 and stops 10. L-shaped beats in the upper part of the drums 5 are diametrically opposed to their vertical axes, perpendicular to the knives 3 of the disc 2 and pivotally attached to the radial protrusions and bandages 11 for jumpers 9 to the side surface of the upper part of the truncated drums 5. The stops 10 L-shaped bills are designed to exclude the possibility of them popping out from the radial protrusions of the bands 11. Impact bars 8 bills on each drum 5 can be installed horizontally in the same plane or different .

A mower with a bilobo screw conditioner operates as follows. When a tractor with a mower moves across the field, the torque from the tractor PTO is transmitted to the discs 2 located on the carrier beam 1 with knives 3 pivotally mounted on them and rigidly mounted on the discs 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. The drums 4 are equipped with screws of the left direction of rotation and consist of plates 6 and 7 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 6, 7 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. The next drum 5 in the upper part is equipped with hinged L-shaped bits made of round steel containing shock rods 8, jumpers 9 and stops 10.

To carry out the conditioning process, the L-shaped beads are installed in the upper part of the drums 5 diametrically opposite to the knives 3 of the disks 2, horizontally in the same plane or different and are pivotally attached to the jumpers 9 to the side surface of the drums 5 by means of the radial protrusions of the bandages 11. Radius protrusions of the bandages 11 provide deviation of the articulated beat when interacting with an obstacle, for example, with a stone while mowing grass at an angle of 90 °. Stops 10 do not allow the beaters to jump out of the hinge brackets 11.

When moving the mower into the grass stand, the hinge knives 3 of the disks 2 pairwise rotating towards each other with the drums 4, 5 with the screws of the left direction of rotation and articulated L-shaped bits cut the grass. The augers of the drums 4 feed grass into the treatment zone with L-shaped beams pivotally mounted on the drums 5. L-shaped beams with rods 8 hit the stems of the plants, injure them, crush them, partially crush them, remove them from the treatment zone and put them in well-aerated rolls (swaths )

The use of drums with hinged L-shaped chisels and augers of the left direction of rotation in the design of the rotary mower, working in pairs and rigidly mounted on the mower disks vertically to the right one after the other in the direction of its movement, helps to improve trauma to the plant stems during mowing grass, improve feed beveled mass in the processing zone by bills, reducing field losses.
