(54) MECHANISM OF THE DRIVE OF THE CUTTING MACHINE OF THE MILLING TYPE

I

The mechanisms for driving rezhushish 1 mower-type devices are known, which contain a rocking washer rigidly connected with a transmission shaft mounted in bearings on the side wall of the harvesting machine. Such a drive mechanism ensures the transfer of movement to only one mower cutter; therefore, on machines for harvesting long-stem crops, having two mowing machines located at different heights, comes with the installation of two drive mechanisms. At. This does not ensure the synchronous counterphase movement of the knives, which leads to the emergence of large, unrestricted loads transferred to the sweeper.

: The purpose of the invention is to provide a synchronous antiphase drive of two mowing knives located at different heights. This is achieved by the fact that in the proposed drive mechanism the transmission shaft is connected to the feed wheel mounted on the swing axis and the hinged end of the upper and lower stretcher knives.

i To drive the upper and lower KOCHaqn knives with different stroke lengths, the swing axis of the rocker arm is installed with the possibility of fixing it in several positions on the side wall of the sweeper and on the rocker arm.

The invention provides several options for positioning the rocker: it washers and rocker arms relative to the transmission shaft.

The transmission shaft may be spaced on either side of the swing washers, and at its free end is a crank that is pivotally connected to the rocker.

The shim washer should be installed at the free end of the transmission shaft, and at the other free end of it, secure the crank associated with the lower mowing knife.

It is advisable to fasten the rocker directly on the swing of the puck, and swing the axle of the swing joint with the transfer shaft.

. FIG. 1 shows the drive mechanism, side view; in fig. 2 is a variant of the embodiment, side view; Fig. 3 is an embodiment, side view.

The drive mechanism consists of a swinging washer J., spanning the drive shaft and rigidly connected to the transmission shaft.

which is mounted on bearings 4 and 5 n the side wall 6 of the sweeper.

The transmission shaft 3 is connected with the yoke 7, placed on the swing axle 8 and attached with cones through hinges 9 and 1O to the mowing knives C and 12 cutting units of apparatuses 13 and 14 located at different heights. The axis 8 of the swing of the rocker arm 7 is installed with the possibility of fixing it in several sockets 15-17 on the side wall 6 of the worm {erochny machine and on the rocker arm 7,

FIG. 1, a transmission shaft 3 is disposed on both sides of swinging washer 1 and, at the free end of the cutting units 13 and 14, has a crank 18 pivotally connected to the rocker arm.

FIG. 2 a swinging washer 1 is fixed on the free end of the transmission shaft 3, on its other free end there is mounted a crank 18 pivotally connected to the lower mowing knife 12,

FIG. 3 rocker arms 7 are fastened directly to the swinging washer, and the swing axis 8 is aligned with the transmission shaft 3.

During the operation of the drive mechanism, the rotational motion of the drive shaft 2 acquires a swinging motion with the help of washers 1, which drives the beam 7 through the transmission shaft 3 and the crank 18 (Fig. 1 and 2) or directly (Fig. 3). The swinging arm 7 causes the mowing knives 11 and 12 of the upper 13 and lower 14 cutting machines of the harvesting machine to reciprocate with the mowers connected with it. At the same time, a synchronous G1 protivo |.) One drive of two cutting devices is provided | ) Atov from ODN01-O mechanism, which reduces the inertial loads transmitted to the sweeper. Fixing the swing axis 8 in several positions on the side panel 6 and the rocker arm 7 allows you to measure

n the stroke length of the mowing knives. When the swing axis 8 is installed in the sockets 16, both axes 11 and 12 have the same stroke length — when the swing axis is installed in the socket 15 and 17 the longer stroke in the first case is for the lower knife, in the second case for the upper knife.
