Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a sunflower harvesting device. Background Art

[0002] Sunflower seeds, i.e. the fruit of sunflower, can be used for food and oil. Sunflower seeds are rich in unsaturated fatty acids, multiple vitamins and trace elements, and they taste delicious. They are a very popular snack and source of edible oil. During the planting process, when the sunflowers are mature, they are harvested to save manpower. Usually, machines are used to harvest in batches at sunflower seed planting sites. The separation device on traditional sunflower harvesters is usually installed at the rear of the harvester. After the sunflower discs are harvested on the harvesting platform, they are transported to the threshing device at the rear through a conveyor belt. In the process of transporting the sunflower discs to the threshing device, it is easy for the sunflower seeds to fall off the sunflower discs and be lost, or the conveyor belts may damage the sunflower seeds, resulting in waste of sunflower seeds.
