“DON” GOES OUT INTO THE FIELD

The demanding task of developing a new family of grain cars to the staff of the enterprises entrusted not accidental. “Rostselmash” — the coeval of the first five — wide experience of combine harvester. June 15, 1930, on the eve of the XVI Congress of the party, the plant was commissioned, and a year later in his experimental shop was assembled a pilot batch of the first Soviet harvesters ‘ Cooperative.

 

Since then released hundreds of thousands of grain cars of different types. In 1964, for the creation of the combine harvester SK-4, and the organization of its mass production the team of specialists of the plant were awarded the Lenin prize. A sign of quality marked by the harvester SK-5 “Niva”.

Labor traditions of the older generation of “Rostselmash” continues young. In creating the “Dona” the active participation of young specialists of the design Bureau, their peers in the experimental shop. Komsomol organization of the Association is a patron of the production of prototypes of the new machine. Nineteen youth teams of CB working to improve its parts. Komsomol members together with their older colleagues developed the original steering column, Domracheva device, threshing drum and other mechanisms.

 

The need to create a new family of cars has arisen due to the fact that the harvesters “Niva” is not always able to cope with the volume of harvesting, which falls to their share. In small fields “field” shows perfectly, but when it is necessary to remove thousands of hectares of grain, it restrains the pace of the harvest. In addition, cleaning is often carried out in difficult weather conditions, during the lodging of crops. To harvest huge areas of grain lands of our country on time and without loss only a powerful modern technology. Significantly increase output per shift of grain cars and will help harvesters “don-1200” and “don-1500” width grind 1200 and 1500 mm. They will be the basic designs on the basis of which will create modifications to the black earth and the harvest on the slopes. Created devices through which the “don” can get not only bread, but corn, sunflower, soy, cereals.

 

 

Self-propelled combine harvester “don” (simplified layout):

 

1 — reel, 2 — conveyor, 3 — threshing cylinder, 4 — engine, 5 — bounce-flail, 6 — vibrator, 7 — distribution screw, 8 — bunker, 9 — straw Walker, 10 — solomonashvili, 11 — rod, 12 — stacker differently, 13 the fingers of the stacker differently, 14 — demolicious device 15, and the upper and lower cleaning sieve, 16 — fan 17 — auger, 18 — grain weight, 19 — AA-bitter, 20 — auger header, 21 — cutting machine.

 

A distinctive feature of the new combine — harvester wide-cut to the same fit for low bread. If cleaning is carried out using split method, the harvesters are equipped with a wider sphere of rolls. These devices increase the efficiency of grain harvesting per shift.

 

For processing of large amounts of bread weight of “Dona” increased size of drum up to 800 mm in diameter. It can clean up to 9 kg mass and the second. “Niva” during this time, handles only 5 kg.

 

An important part of any combine hopper of grain. It is the size of the new machine 6 m3 which is two times more than the “Field”. Thanks to the hopper increased capacity “don” rarely stops for unloading grain into a truck body.

 

Engine “Dona” — diesel with a capacity of either 160 or 220 HP, the Chassis can be equipped with mechanical or hydraulic drive. The latter increases the efficiency of the motor, providing variable speed control.
