Description

Technical Field

[0001] The present invention relates to the field of picking machines, and particularly to a chrysanthemum picking machine. Background Art

[0002] Chrysanthemum is a perennial herbaceous plant belonging to the genus Chrysanthemum in the Compositae family. Its flowers contain various beneficial components, including volatile oils, flavonoids, polysaccharides, triterpenoids, and trace elements required by the human body. Chrysanthemum can be used not only for medicinal purposes but also for food, and as a raw material for making daily necessities such as toothpaste and hand cream, it has high economic value.

[0003] At present, most of the chrysanthemum picking in domestic rural planting bases is still done manually. Some are picked by hand, while some are picked using tools with comb teeth. These picking methods have high labor costs, cause a large burden on the human body, and the flowering period of chrysanthemum is short. If the picking efficiency is low, the chrysanthemums will wither. In case of rainy weather, if the picking is not timely, the chrysanthemums will lose their use value. At this time, the manual picking method is no longer suitable for the current large-scale planting environment and cannot keep up with the development pace of large-scale and industrialized chrysanthemum planting. Therefore, the present invention provides a chrysanthemum picking machine. Summary of the Invention

Under the rotation harvesting action and the guidance of the chrysanthemum baffle, the chrysanthemums are turned above the conveying cylinder and fall into the inside of the conveying cylinder through the opening at the upper part of the conveying cylinder, realizing the collection of chrysanthemums. There is a screw shaft for rotating conveyance inside the conveying cylinder. Through the conveyance of the screw shaft, the chrysanthemums are sent to the end of the conveying cylinder to complete the collection action inside the chrysanthemum harvesting component. The structure is simple and reliable, and the collection efficiency is high. Since a hollow screw shaft is used, the damage to the chrysanthemums is small. The air pipe installation port in the chrysanthemum harvesting component is connected to the granary through the second air pipe, and the granary is connected to the air suction port of the fan through the third air pipe, further collecting the chrysanthemums collected at the end of the chrysanthemum harvesting component into the granary, which is convenient for personnel to unload.
