RU2371902C2 - Rotary mowing machine with conditioner - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machine-building and can be used in machines for fodder production. Rotary mowing machine with conditioner contains bearing bar with even number of rotating discs. On discs blades are fixed and drums with beater bars. Beater bars have concave form and are installed in upper part of drums by means of cuts of rectangular form made in perpendicular planes at different height on vertical, in marquee-like or cup-like way perpendicular or parallel to blades. Beater bars are fastened inside drums by means of splint pins in thrust manner.

EFFECT: increasing efficiency of fodder production.

Description

The invention relates to agriculture, in particular to machines for feed production.

Known mower with air conditioning [1], containing a rotary disk cutting apparatus, conditioner, swather. The rotor of the conditioning device (air conditioner), located in the casing behind the rotary cutting device, equipped with pivotally fixed blade-shaped cutting and billet elements placed on its surface in six rows, the elements of one row located relative to the elements of the other row in a checkerboard pattern, rotating from bottom to top, provides trauma to the stems of mowed plants when interacting with the deck installed at the top of the entrance to the treatment zone and transportation along the inner surface of the upper image the casing of the casing until it comes into contact with the baffle plate pivotally fixed at its end, after which the treated mass falls onto the mass stacker installed under the flap, and from it onto the stub, and the degree of mass processing is controlled by changing the gap Q between the blade-shaped cutting elements of the rotor and deck , as well as the rotor speed by transmitting torque to an intermediate sprocket, with which, respectively, a chain to the rotor sprocket. The angle of inclination of the baffle plate is regulated by holes in the strips pivotally mounted on the sides of the casing. The angle of inclination of the swather is adjusted by shortening or lengthening the suspension chain.

The disadvantage of this mower is the material consumption and design complexity.

Known mower conditioner [2], containing a rotary cutting apparatus with an even number of rotating disks with fixed knives and vertically mounted drums, a conditioner including bills and deck. The bills are mounted on the drum, and the deck is made V-shaped, consisting of two parts with a common axis of rotation located between the drums. The saws are installed along a helical line on the generatrix of the drum, the direction of the beginning of winding of which from the base of the drum is opposite to the direction of movement of the mass. The saws are installed with the ability to change the position of the beginning of the screw winding relative to the knives in the horizontal plane.

The disadvantage of this mower conditioner is the design complexity.

The purpose of the invention is to reduce material consumption and simplify the design.

This goal is achieved by the fact that the rotary mower with air conditioning contains a cutting device with an even number of rotating disks with knives fixed to them and vertically mounted drums with bills. Concave bills are installed in the upper part of the drums by means of rectangular cuts made in mutually perpendicular planes at different vertical heights, with a tent or a cup perpendicular or parallel to the lower knives, and the beats are secured from the inside of the drums with cotter pins.

Figure 1 shows a front view of a rotary mower with air conditioning, figure 2 is a sectional drum.

A rotary mower with air conditioning contains a supporting beam 1 with an even number of rotating disks 2 with knives 3 fixed on them and vertically mounted drums 4 with bars 5. The bars 5 are concave and are installed in the upper part of the drums 4 by means of rectangular cuts 7, 8 made in mutually perpendicular planes at different heights vertically, with a tent or bowl, perpendicularly or parallel to the lower knives 3. The beat 5 is fastened from the inside of the drums 4 by means of cotter pins 9 in the ra dispute.

A rotary mower with air conditioning operates as follows. When the tractor with the mower moves across the field, the torque from the tractor PTO is transmitted to the disks 2 with the knives 3 attached to them and the vertically mounted drums 4 with the saws 5. When the rotary mower is moved to the grass, the lower knives of the 3 disks 2 cut the grass, and beats 5, having a concave shape and installed in the upper part of the drums 4 by means of slots 7 of a rectangular shape, made in mutually perpendicular planes, with a tent or a cup, perpendicular or parallel to the lower knives 3 depending ti requirements from the processing of grass, hit the plant stems, injure their cuticle and partially scraped off. Knives 3 and bills 5 pick up the cut grass and take it out for the supporting beam. Due to the fact that bills 5 are installed in a tent and a bowl, they injure the stems of plants at different heights, thereby causing multiple damage to them, which greatly speeds up the drying of mowed grass. Depending on the height of the grass stand, beats 5 by means of slots 7, 8 of a rectangular shape can be installed in the drum 4 at different vertical heights.
