Sun sunflower harvester Profi
― intended for high-quality and effective sunflower (sunflower) harvesting. The technical features of the harvester allow you to harvest various varieties of sunflower, working in any direction, with minimal losses in the shortest possible time. The harvester also proved to be effective in harvesting fallen sunflowers.
Sun Profi, The harvester is an improved, modified model of the sunflower harvester, ZhSN, John Greaves, as well as the Italian one - "Zaffrani".
Principle of actionharvesters for harvesting sunflowers Sun Profi.
The harvester separates the harvested mass of sunflower with the help of special separators of stem lifters - lifters, which provide high penetrating ability inside the harvested crop, providing the best conditions for cutting the baskets and protection against seed spillage. Next, the mass of sunflower baskets is captured by a reel, which in the harvesterfor harvesting sunflowers has a more rigid structure than in the grain one, and is covered with a special protective cover that prevents the sunflower caps from being thrown out. The captured mass is fed to the cutting device of the harvester, and the baskets are cut by a special knife with a cutting frequency of 950 double strokes per minute. Then, with the help of an auger, the cut mass is sent to the более жесткую конструкцию, чем в зерновой, и закрыто специальным защитным кожухом, что предотвращает выбрасывание шляпок подсолнечника наружу. Захваченная масса подводиться к режущему аппарату жатки, а срезание корзинок обеспечивается специальным ножом с частотой среза 950 двойных ходов в минуту. Затем скошенная масса при помощи шнека направляется в harvester.
The main advantages of the Sun Profi sunflower harvester compared to the sunflower harvesting device (lifters):
1. The quality of cleaning is significantly higher. Losses on the harvester do not exceed 1%. Device losses range from 100 to 150 kg/ha. Harvesters - up to 15 kg. Thanks to the better harvesting process, the losses fully pay for themselves on 250-300 hectares of sunflower. The economic advantages of a harvester for harvesting sunflowers can be found in the article "Recommendations for harvesting sunflowers" on our website in the Articles section.
2. The harvester, in contrast to the device - lifters, allows you to harvest sunflowers with the same quality, both with row sowing and continuous sowing.
3. The use of a grain harvester, re-equipped for sunflower harvesting with the help of an attachment, significantly reduces its service life. The harvester is designed specifically for sunflower harvesting and has all the technical and operational characteristics necessary for its long-term use.
4. The harvester for harvesting sunflower allows you to cut only the baskets (caps) of sunflower, leaving the stems and leaves on the ground, which guarantees the high quality of the obtained harvest (up to 1% dirt in the container) and the correct operation of the combine thresher. In addition, due to the fact that sunflower stalks do not fall into the harvester, the humidity of the harvested seed decreases.
5. The simple assembly system of the Sun Profi sunflower harvester allows you to switch from harvesting grain crops to sunflower much faster, does not require the involvement of additional workers and resources (1 operator is enough) for its operation.(//tractor-service.com)
6. The harvesting speed of the harvester is 30% higher than that of the device, which significantly shortens the sunflower harvesting period.
The main advantages of a sunflower harvester compared to other domestic and imported manufacturers (Zaffrani, John Greaves, ZhSN, etc.), as well as an earlier model:
1. The reel drive, which was previously located on the right side of the harvester, was moved to the left side, which made it possible to separate the rotation of the auger and the reel (previously, the reel rotated from the auger shaft). These changes made it possible to significantly reduce the load on the working nodes of the sunflower harvester, increase its reliability, increase the resource not only of mechanical gears, but also of the auger itself.
2. An improved method of fastening the reel cover and the protective net of the harvester auger. This made it possible to improve the quality of sunflower harvesting (earlier the caps that fell on the net fell outside the harvester), as well as to improve the overview of the auger while working in the field.
3. The resource of the cardan transmission of the harvester for sunflower harvesting is increased due to the reduction of the angle of collapse of its hinges.
4. Increased reliability of the header auger as a result of replacing the auger trunnion with a calibrated shaft that is fixed in a clip.
5. Strengthening of the frame of the harvester for harvesting sunflower due to the use of supporting frame pipes of a larger section.
6. The moment of discarding sunflower seeds and caps with a reel back onto the stem lifters is eliminated due to the creation of a special "seed trap" inside the harvester itself.
7. Increased productivity of the harvester for sunflower harvesting due to an increase in the cutting speed by 5%, which allows to reduce the harvesting time.
8. The shape of the toes of the lifters and the construction of the sidewalls allow to provide excellent penetrating ability, as well as to separate the mass of the sunflower regardless of the direction of movement of the harvester.
9. The weight of the sunflower harvester is reduced, which allows you to consume less fuel during harvesting.
