Description

Perilla seed grain harvester

Technical Field

The invention relates to the field of perilla seed grain harvesters, in particular to a perilla seed grain harvester.

Background

Perilla is an annual herb of Perilla of Labiatae, and can be used for medicine and spice, the part used as medicine mainly comprises stem and leaf and seed, and the leaf is diuretic with effects of inducing perspiration, relieving cough, and invigorating stomach, and has analgesic, tranquilizing, and detoxicating effects, and can be used for treating common cold; the stem has the effect of calming qi and preventing miscarriage; the perilla seeds are also called perilla seeds, oil squeezed from the perilla seeds is called perilla oil for eating, and the perilla seeds have an antiseptic effect and are used for industry, the perilla seeds grow on perilla clusters, the perilla clusters are shaped like wheat ears, when the perilla seeds are collected, the ears are pinched by one hand, the perilla seeds are cut off from the roots of the ears by the other hand, the cut ears are placed in a collecting barrel, the collected ears are flatly spread on a plastic film for exposure to the sun, then the ears are beaten, the perilla seeds fall off from the ears, and then the perilla seeds are collected to finish the collection work of the perilla seeds.

However, the ripening time of perilla seeds in different areas of different perilla plants, different fruit ears of the same perilla plant and the same fruit ear is different, the time for harvesting the fruit ears is usually suitable for harvesting the fruit ears at one time when 40-50% of the perilla seeds are ripe, the ripe perilla seeds are easy to fall off under the action of external force, so people are required to control the fruit ears as accurately as possible, the operation difficulty is high, the target fruit ear and the rest fruit ears on the perilla plant can be vibrated by carelessness, the ripe perilla seeds fall off and are wasted, the collection rate of the perilla seeds is low, the perilla seeds are required to be put into a collection barrel by bending down every time when the fruit ears are collected, frequent back and forth movement is required, the labor intensity is high, and therefore, a perilla seed harvesting machine needs to be designed urgently.
