Description

Technical Field

[0001] The utility model relates to the technical field of rotary cutting harvesters, in particular to a rotary cutting harvester. Background Art

[0002] Safflower (Carthamus tinctorius L.) is an annual herbaceous plant of the Asteraceae family and the genus Carthamus. It can reach 150 cm in height. The stem is erect, branched at the top, smooth and glabrous. The leaves are hard, leathery, shiny, sessile at the base, and semi-amplexicaul. The inflorescence is capitulate, with elliptical or ovate-lanceolate bracts and ovate involucre, glabrous and glandular-free. The small flowers are red or orange-red, all bisexual, and the achenes are obovate. They bloom and bear fruit from May to August. After the safflower grows and matures, it needs to be harvested, so a rotary cutting harvester is needed.

[0003] The existing method of harvesting safflower is generally to manually pick the filaments by staff, or to pick them by a picker, wherein the picker generally includes two arc-shaped tubes movably connected by a torsion spring and a movable shaft, and the other ends of the two arc-shaped tubes are blades. When in use, the filaments of the safflower are allowed to enter the interior of the two arc-shaped tubes, and then the two arc-shaped tubes are pinched together. At this time, the filaments of the safflower can be cut off by the two blades. Due to the action of the torsion spring, the two arc-shaped tubes can be automatically opened, and then the filaments of the safflower are placed in the collection tube. This reciprocating process is repeated to complete the harvesting of the safflower.

[0004] The existing safflower harvesting method has the following shortcomings: the safflower filaments have to be picked off manually, resulting in low picking efficiency; and the picking method using a picker causes hand muscle soreness due to the long-term pinching of two arc-shaped tubes. Therefore, it is necessary to propose a rotary cutting harvester to solve the above problems. Utility Model Content
