Manual persicaria hydropiper collecting device

Abstract

The invention relates to the technical field of medicine collection, and discloses a manual persicaria hydropiper collecting device which comprises a connecting plate, rotating balls A and a pull rod.A vertical rod is fixedly installed at the top of the connecting plate, a sliding block is fixedly installed at the bottom end of the pull rod, and ball grooves clamped with the eight rotating ballsA are formed in the arc-shaped side wall of the connecting plate; and side plates are fixedly mounted on the spherical outer walls of the eight rotating balls A. According to the manual persicaria hydropiper collecting device, the pull rod is pulled, an extrusion rod is pulled through a steel wire rope, eight sets of side plates are driven to be combined, persicaria hydropiper which cannot be directly reached by medicine collecting personnel on the water bank side is wrapped, and meanwhile spike-shaped flowers on the stem portion and the outer wall of the persicaria hydropiper are wrapped in the eight sets of combined side plates at the same time; and after the pull rod is pulled to directly break the persicaria hydropiper through the eight sets of combined side plates, collection of the persicaria hydropiper is achieved. The manual persicaria hydropiper collecting device is simple in structure, the problem that the persicaria hydropiper growing on the water bank side cannot be directly picked is solved, and the persicaria hydropiper picking efficiency of the medicine picking personnel is also improved.

Description

technical field [0001] The invention relates to the technical field of herb collection, in particular to a manual collection device for Polygonum hydroponica. Background technique [0002] Polygonum is an annual herb belonging to the family Polygonaceae, up to 70 cm high. Stem erect, multi-branched, leaves lanceolate or elliptic-lanceolate, glabrous on both sides, covered with brown dots, with acrid taste, leaf axils with cleistogamous fertilized flowers; stipules tubular, membranous, brown, racemes Spike-shaped, terminal or axillary, flowers sparse, bracts funnel-shaped, green, margin membranous, with 5 flowers in each bract; pedicel longer than bracts; perianth green, tepals elliptic, stigma capitate. Achenes ovate. The whole plant of Polygonum waterus is used as medicine to reduce swelling, detoxify, diuresis, and stop dysentery.

AI Technical Summary

Problems solved by technology

[0003] Polygonum water grows on the water bank, and the herbal collectors often need to go down to the water bank in person to pick Polygonum water, and sometimes even need to help the ship to pick Polygonum water on the water bank to a certain extent. It is time-consuming and labor-intensive. The existing artificial technology has a low efficiency in picking Polygonum water. Not only does it have certain risks, it needs the herb collectors to go down to the shore first, and the picking efficiency of Polygonum water is low. When the Polygonum hydroponica growing vertically upwards is pulled and shortened, it is easy to cause the spike-shaped flowers on the outer wall of Polygonum hydroponica to fall off, which easily leads to the problem of low picking efficiency of the herb collectors.
