PZS-8 sunflower harvester, Dnipropetrovsk region.

Sunflower harvester CCD-8. Aggregated to all Slavutych, Don-1500, CLAAS, John Deere, Case, Massey Ferguson, Top Liner, New Holland and other combines work at higher speeds, which increases productivity;

2) the absence of longitudinal conveyors that feed the cut sunflower baskets to the transverse auger increases the reliability of the design of the CCS-8 harvester;

3) a smooth and shock-free cut of the stems occurs with the help of installed two disc knives, which reduces losses and increases the amount of the obtained sunflower crop. Also, special grippers are used on these knives, which ensure smooth feeding of the cut baskets to the auger of the harvester;

4) the hood of the channel is made with special edges, due to which the spillage of sunflower seeds outside the harvester is reduced;

5) in order to avoid hanging stems on the front shield when harvesting a high-growing sunflower, reflective screens are installed on these shields.

Technical characteristics:

- number of rows – 8 pcs.(//tractor-service.com)

- row width - 70 cm

- width of capture - 5.6 m

- productivity – 5.6 ha/h

- working speed - up to 9 km/h

The working speed of the CCS-8 sunflower harvester is up to 12 km/h. At the same time, the loss of seeds will be no more than 2%. The harvester can be hung on John Deere, CLAAS, Case CASE IH, NewHolland New Holland, Massey Ferguson MASSEY FERGUSON, Akros, Vector, Slavutych, DON-1500 , Palesse, Skif and other combine harvesters of distant and close foreign production. CCS-8 has a number of advantages over similar harvesters: the directness of the harvesting process ensures work at higher speeds without increasing the loss of seeds (stems in the channels of the harvester are fed without tilting in the direction of its longitudinal axis). A more reliable design due to the absence of longitudinal conveyors for feeding the cut heads to the transverse auger. Due to the use of round knives in cutting devices, a smooth, shock-free cut is ensured, which reduces the loss of free seeds. High reliability of the technological process, as the supply of stems to the cutting apparatus is carried out by a pair of chains with legs. the design of the copying capes allows you to lift fallen and fallen stems. Special reflective screens prevent the stems from hanging on the shield when harvesting high-stemmed sunflowers. It is known that the seeds in the basket do not ripen at the same time, and by the beginning of the harvest, a significant part (and the most conditioned) overripes and falls off at the slightest touch when the stems and baskets with passive dividers, the reel shield and the slant of the cutting device of the grain harvester on which the device for harvesting sunflower is hung with passive lifters. according to the results of many years of tests, losses when harvesting sunflower with lifters are about 5% to 10%! In order to prevent these losses, CCD harvesters do not have a reel, and there are special containers for collecting seeds in the hoods of the troughs, and chain conveyors are installed in the working channels of the troughs, the speed of which is comparable to the speed of the harvester. The speed of disk knives is also coordinated with the speed of conveyors.
