A kind of equipment and method for defoliation of petiole plants

Abstract

The invention relates to equipment and a method for removing leaves from plants with leaf stalks. The equipment is characterized in that a leaf removal drum is erected on the upper side of a framework via a drum shaft, circular drum spoke plates are arranged at the left end and the right end of the drum shaft, the left end and the right end of each leaf removal corrugated rod are respectively connected onto the left drum spoke plate and the right drum spoke plate, and the multiple leaf removal corrugated rods are arranged along the circumferences of the drum spoke plates to form equal angles and are parallel to the drum shaft; oblique grooves are equidistantly formed in the outer surfaces of the leaf removal corrugated rods; an arc-shaped drum bottom plate is arranged below the leaf removal drum. The equipment and the method have the advantages that the leaves can be separated from stalks by the aid of shear stress generated by speed difference of the leaf removal drum and the drum bottom plate according to characteristics of physical forms and stress concentration of the leaf stalks and the stalks of the plants, direct mechanical shearing carried out by existing equipment can be omitted, and the integrity of the leaves and the stalks of the plants can be guaranteed to the greatest extent; quick and efficient leaf removal operation can be carried out on the plants, such as Artemisia vulgaris and alfalfa, with the leaf stalks, accordingly, the labor intensity can be relieved to a great extent, and the equipment and the method are applicable to large-scale industrial production.

Description

Technical field [0001] The invention belongs to the technical field of separation of stems and leaves, and particularly relates to a device and method for defoliating plants with petioles. Background technique [0002] Petiole plants are plants in which the main branch exists in plant morphology, and the side branches are short and most of the leaves grow directly on the main branch. Among them, wormwood and alfalfa are represented. The above two plants have high economic value, but due to the different composition of leaves and stalks, the practical value is very different. It is often necessary to separate the stalks and leaves for further processing and utilization. Taking wormwood as an example, wormwood leaves are the most concentrated part of wormwood, but wormwood leaves cannot be harvested separately. Therefore, the separation of wormwood leaves and wormwood stems after harvest is a key step in determining whether a large number of wormwood leaves can be provided. There ...

Problems solved by technology

Taking wormwood as an example, wormwood leaves are the most concentrated part of the active ingredients in wormwood, but wormwood leaves cannot be harvested alone, so the separation of wormwood leaves and wormwood stems after harvest is a key step in determining whether a large number of wormwood leaves can be provided. There is no dedicated stem and leaf separation equipment, and the stem and leaf separation process relies on manual labor, which is labor intensive and low in production efficiency

[0003] Existing a large amount of introductions about stem-leaf separation equipment, wherein a kind of rosemary stem-leaf separator (CN204471436U) realizes stem-leaf separation by separating knife, but separating knife easily causes damage to plant leaf, loses active ingredient; Tight plants, cumbersome operation; a new type of plant stem and leaf separator (CN204544778U) uses multiple pairs of belts to achieve defoliation through different belt differential speeds, because the squeeze between the belts will cause the leaves to dejuice and lose their active ingredients
