    10 passes in the area of the side walls with ball heads 23, therefore 7 under the bottom of the reaping part 2 to which the support plates 33 provide for the levers 11, and the plates 25 are only on the reverse side of both of them and are located in the middle of the bolster plates 25.
    FIELD OF THE INVENTION The invention relates to agricultural machinery industry, namely to the drive of the cutting apparatus of the reaping part of a mower, mowing machine, reaper or header of a combine harvester. From the GDR patent No. 79173, the drive of the cutting apparatus of wide-cut reapers is known. The main drive shaft, which extends across the entire width of the bottom of the header, has a swinging axle at both ends, bent at an angle in the same direction. Over the rocker washers and forks, drive rocker arms move. The drive arms are connected on both sides outside the side walls with the heads of the knives. A disadvantage of such a drive of the cutting apparatus is that the arrangement; its on the outer sides of the side walls requires the presence of wide walls. Located at the end of the knife segment, the deeply lying knife head leaves, on the seeding side outside the side wall, a sliding wake. Plants to be harvested during davlivi1 and during subsequent cutting cannot be covered by knives. The part of the knife that is located outside the side wall outside the planting area, as well as the driven arms located at the end of the knife head, presses the intended for harvesting plants to the soil, which leads to a significant yield loss. FRG No. 2411232 also knows the drive of a double knife of the header, in which both blade of the knife are set in motion at opposite Hapyjink ends on the heads of the knives with the help of symmetrically oscillating angular elements through rods. Moreover, at both ends of the drive shaft, eccentrics are fixed which drive the connecting rods. This drive with a crankshaft does not require a wide design, side walls. A disadvantage of the known actuator is the formation of a sliding wake on the seeding side due to the knife head plates located outside. In addition, the eccentrics and connecting rods are made so heavy and material-intensive that this variant of the drive of the wide-grip cutting apparatus with a high speed of movement of the knives is unacceptable due to the large mass. The aim of the invention is to create a drive of a knife for harvesting stem crops, the wide cutting harvest parts of which have narrow side walls and do not leave, on the seeding side, a sliding wake leading to loss of yield. The purpose of the invention is to design a knife drive for a wide-grip stalk crop so that the impact points on the transfer of drive force to the mower knife are not located outside the side walls and that a high speed of the knife is achieved with a narrow design and light weight. by the fact that on both sides under the bottom of the reaping part a crank lever is located between the mounting plates secured to the frame. Arranged transversely to the direction of movement, the ends of the crank arm, extending outward through the slots of the side walls in the hinge bearings, are connected to the rods. The connecting rods are connected to the connecting rod necks located on the crank disks on both sides, behind the bottom of the reaping part of the fixed crankshafts. In order to regulate the knife overlap ratio, the crankshafts at the rear of both side walls in the bearing plates are re- placed. The cranked levers located under the bottom of the reaping part have protruding bearing bushings on both sides. Bearing bolts fixed to the shields are inserted into the sub-type i bushings at the top and bottom. Thus, the completed crank levers are mounted on the guards with the help of screwed-through bolts passing through the longitudinal holes of the adjusting plate so that the crank levers can be set to a position perpendicular to the blade plane at any time. The forward-facing ends of the crank arms pass through the holes in the bottom of the reaping part to the ball heads of the blade heads of the knives and are connected to them in the ball socket. With the goal of preventing the oscillating ends of the corner elements and the windings of the knives heads from going back and forth due to the oscillating ends of the heads of the knives that pass through the slots, the external clamps of the knives fixed on the bottom of the reaping part, adjustable with the help of the adjusting bolt, are designed as a comprehensive cover for moving the lower parts. The guards of the knife heads are fixed on the knives with a shift from the outer edge inward by at least three stroke lengths. Due to the fact that the heads of the knives are always in the area of the side walls, the occurrence of a sliding track at the seeding boundary is excluded, which in turn leads to the elimination of crop losses. For the purpose of selectively using dual knife knives, it is necessary to position the ball heads on the knife shields of the knife relative to the knife line of the knife with a displacement backward. The resulting forces, due to the transfer of the point of application of force backward, are adopted by supporting plates located at the outer ends of both blade heads. In another embodiment of the device, bending moments are eliminated by positioning the rocker arms. Located at the inner end of the flaps of the heads of the rocker arm knives have more than 634 long runs, than the distance from the point of rotation of the crank arm to the point of application of force, the ball heads. In the embodiment, when inside the side walls under the bottom of the reaping part the connecting rods are brought to the crankshaft, the guards of the heads of the knives are equipped with ball heads located in the middle. At the same time, on the reverse sides of both ends of the blade heads of the knives, there are planes of touch, which help to ensure that the freed ends of the knife leave no marks on the seeding line, which helps to eliminate crop losses. The required support areas or support plates for eliminating the occurring moments of the bend are located either inside the clamps of the knives or in the fingers of the knives, so that no additional nodes are required. The overlap of the blades is set by paramuting the crankshafts in the bearing plates, which in turn allows the manufacture of connecting rods located on both sides of the connecting rod, necks of bent material of light construction. FIG. 1 shows one of the sides of the knife drive located side-by-side, top view of FIG. 2, section A-A in FIG. one; in fig. 3 arrangement of blades of the heads of knives when using a double cutting apparatus; in fig. 4 shows the arrangement of the blade heads in accordance with FIG. 1J ya fig. 5 shows an embodiment of the device with a beam in FIG. 6 - the same, with a ball head bolt located in the middle. Behind the rear wall 1 of the bottom of the reaping part 2 there is a drive shaft 3. On the drive shaft 3, crankshafts 5 are located in the clips 4. The loops 5 are located in movable shields 6 on the side walls 7 of the bottom of the reaping part 2 and end up with crank pins 9 fixed in the crank The disks 8 protrude beyond the side walls 7. To the connecting rod journals 9 along the outer sides of the side walls 7 the connecting rods 10 .. Under the bottom 2 there are cranked levers 11, the ends of which are directed outwards, passing through the slots 12 of the side walls 7 and connecting Yens in hinge podshpnik 13 with the rod us 10. The crank levers 11 have in the centers of rotation on both sides of the alignment bearing sleeves 14 on which the hinge bearings 15 are located above and below the bearing 15. Bearing sleeves 17 are inserted into the hinge bearings 15 and fixed on the hubs 16. Thus, with the help of the upper and lower flaps 16, cranked levers 11, fixed under the bottom of the reaping part 2 in the screwed-in connection 21 and rearranged in the longitudinal holes 20 between the mounting plates 19, located on the the landing part 18. The forward-facing ends of the crank levers 11 pass through the openings 22 of the bottom of the harvesting part 2 and are hinged in the heads of the ball bolts 23 with the plates of the heads of the knives 25 attached to the mowing knives 24, and the crankshaft 11 must be perpendicular to planes 24. For this purpose, there are complete cranked levers 11, rearranged in the longitudinal openings 20 of the flaps 19 and secured with screwed joints 21 on the shields 16. To prevent clogging over the bottom 22 passing through the slots 22 The common ends of the crank levers 11 and above the holoks of the ball 23 knives-head plates 25 are provided with knife grips 26, specially designed as a comprehensive protective device and located on the bottom of the harvester part 2. 27, located in the knife holders 26; The ends of the crank levers 11 passing laterally through the holes, and outside the side walls 7, moving the rods 10 to the outside by means of the rods 10, which are located on both side walls 7 of the side shields 28. In order to selectively use the two-blade cutting mechanism, the bolts with ball heads 23 located on the shield of the heads of the knives 25 are shifted by the amount X to the line of the point of the knives of the knives 24. On the basis of the displacement of the point of application, the moments of bending on the knives 24 . To balance these moments at the ends of the relatively long shields of the heads of the knives 25 are located on both sides of the plane of abutment 29, on which are located in this area the shields of the knives 30 and plychs 31, instead of the planes of the adjoining 29 to eliminate the moment of bending at the ends of the plates of the heads of the knives 25 rocker arms 32 should be located. Rocker arms 32 should have a longer lever than the distance from the point of application of force to the ball heads of the 23 plates of the heads of the knives 25.
