In addition to toto, for the purpose of this kind of combine lt, l of harvesting the seed of herbs, a grater drum of the usual type is installed in the logger of the combine.

The peculiarity of the go from the combine also lies in the fact that the drive to the knife is e; |, the non-knife blade with the oscillating shaft of the axeshift is using an elastic liner.

FIG. 1 shows a longitudinal schematic section of a combine harvester; ka fig. 2-view of the combine from above; on 4gs. 3-drive to the knife.

The main parts of the header of the combine are one-sided, not: cutting machine / conventional type, dividers 2 right and left, fitted on the inner walls with guards 4, slat conveyor 3, reel 5, additional conveyor 6 helera and screw-beater 7, serving for narrowing bread flow and supply of ei-o to the threshing drum.

The thresher of the combine includes a threshing drum 9 with a deck 16, a straw strap 6apa6aii (co.komoches) / S, a key straw walker with 11, a chained floor :: chats 1 transporter / 2. the first cleaning 13, the second cleaning 14, a bunker / 5 for grain, a grating drum .0 and a straw walker with / 7.

The work of the njioTCKaeT combine in the following way. The stems, cut by the cutting; by the apparatus / under the influence of an adjustable reel 5, are fed by a slat conveyor 3 into the receiving chamber of the thresher. When this occurs, the grain mass is narrowed from the cutting width of the cutting apparatus B to the working width of the thresher (Fig. 2) approximately 2.5 times. In the upper part of the conveyor 3, the bread mass is crimped by an additional crimp chain-slat conveyor 6, after which it is subjected to the action of the screw connector 7, which has spirals in the right and left parts, and the flow is reduced to the threshing drum in the middle lobe five.

In order to avoid retraction of the stems from the receiving chamber to the cutting unit by the lower pluton of the conveyor 5, a smooth roller 18 is stirred near the drive roller next to the last one. 6 rotates around the center of the drive roller in the direction indicated by the arrow / 4.

After the threshing of the grain mass with the threshing apparatus, a significant part of the pile through the holes in deck 16 is turned onto a chain-slat conveyor 12. The straw with the remaining part of the pile is exposed to the straw walker and the keyboard walker //, while the straw walker produces the straw, g preliminary separation and distribution of the wet product, and the straw walker with the final separation of straw from the straw.

From the conveyor 12 and the straw walker, the pile goes successively to the upper and lower sieves of the first cleaning 13 and at the same time intensively blows air from the fan 27. Passing through the lower sieve, the grain is fed to Btoru, cleaning 14, He presented two rotating cylindrical sieves on one side of the smallpox, having simultaneously reciprocating motion.

The cleaned grain enters the hopper 15, and then into the bags. With the help of chuck 22, having right and left helix, small and large weed seeds are fed to the sleeve, which directs them to the weed buncher 23, 1, periodically cleaned.

The non threshed ears from the first cleaning sieves are fed to a 24 / amp; Elevator 25 is returned to the straw bins for re-threshing.

Straw and chaff enter the straw press 17 and are pressed into one common current, which is automatically discharged onto the field.

The working elements of the combine are driven and self-propelled from the engine 26 mounted above or below the threshing machine. The leading wheels 27 or tracks are located at the front of the combine, and the steered wheels 28 at the rear.

For harvesting grass testes with direct seed wiping in the field, the combine is equipped with a grater apparatus 20, installed instead of a straw press 17.

The blade of the cutting apparatus (Fig. 3) is driven from an oscillating shaft 29 connected to the blade strip 30 by means of a bracket 31 with an elastic insert 32.
