Description

Technical Field

[0001] The present invention relates to the technical field of crop leaf and stalk separation, and particularly to a wormwood leaf and stalk separation device. Background Art

[0002] Wormwood (scientific name: Artemisia argyi H.Lév.&Vaniot), alias: Xiao Mao, Bing Tai, E Cao, Xiang Ai, Qi Ai, Ai Xiao, Ai Hao, Peng Gao, Ai, Jiu Cao, Yi Cao, Huang Cao, Ai Rong, etc. It is a perennial herb or slightly semi-shrubby, and the plant has a strong aroma. This special fragrance has the effect of repelling mosquitoes and insects. Wormwood has the effects of regulating menstruation and stopping bleeding, preventing miscarriage and stopping metrorrhagia, dispelling cold and dampness. It is used to treat irregular menstruation, menstrual pain and abdominal pain, miscarriage, uterine bleeding, and can also cure rheumatic arthritis, headache, and postpartum wind. Because it can make ice round and can be used to moxibustion various diseases, it is the most commonly used medicine by doctors. Modern experimental studies have proved that Artemisia argyi has antibacterial and antiviral effects; anti-asthmatic, antitussive and expectorant effects; hemostatic and anticoagulant effects; sedative and anti-allergic effects; liver protection and gallbladder protection effects, etc. The dried and mashed Artemisia argyi is made into moxa floss, and moxa sticks are made for moxibustion. In recent years, with the increasing attention of people to health, the moxibustion physiotherapy industry has developed rapidly, and the demand for wormwood as a raw material is also increasing, and the planting area and scale of wormwood are gradually expanding.

[0003] In the use of wormwood, only the leaf part is needed. Therefore, after harvesting wormwood, it is necessary to separate the leaves and stalks. The traditional separation method is manual sorting, which has a high labor intensity for workers, low work efficiency, high enterprise labor costs, and causes great harm to the workers' hands after long-term and large-scale work. The workers' hands are prone to cracking and pain after sorting the leaves. Therefore, a fast and efficient leaf and stalk separation device is needed. In addition, although the traditional leaf and stalk separator makes up for the deficiencies of the traditional manual leaf removal method to a certain extent, the integrity of the wormwood leaves removed is not high, and it is easy to cause leaf and stalk mixing after leaf removal, increasing the labor intensity of the subsequent separation, which directly affects the sales revenue of farmers.

[0004] There are also the above-mentioned deficiencies in the separation of the stalks and leaves of many plants similar to wormwood that require stalk and leaf separation. Summary of the Invention

[0005] The purpose of the present invention is to provide a wormwood leaf and stalk separation device to make up for the defects of the existing technology. The leaf and stalk separation effect of the leaf and stalk separation device is obvious, greatly reducing the manual labor and improving the economic benefits.

A discharge plate is arranged at the feeding port. The discharge plate forms an angle of 120° with the horizontal direction. An air inlet is arranged on the side wall below the discharge port. The air inlet is connected to the fan through a duct. A flow dividing plate forming an angle of 20° with the horizontal direction is arranged at the air inlet. Two discharge ports are arranged at the bottom of the leaf and stem collection box. The two discharge ports are separated by a concave baffle, and the concave baffle is facing the air blowing direction. The end close to the fan of the two discharge ports is the stem collection area, and the end far from the fan is the leaf collection area. An air outlet is arranged at the bottom of the other side wall of the leaf and stem collection box opposite to the air inlet.

[0010] Further, the brush belt type separation device is fixed above the conveying device through four height control screw frames evenly arranged on both sides. The height of the brush belt type separation device is adjusted by the screws on the height control screw frames. The distance between the top of the belt type flexible brush and the surface of the conveyor belt is 1 - 4 mm. The brush belt type separation device separates the leaves and stems of Artemisia argyi through the belt type flexible brush by the reverse differential movement of two symmetrically distributed rollers.

[0011] Further, the conveyor belt of the conveying device adopts a cross-shaped grass pattern conveyor belt, which increases the friction between the conveying device and Artemisia argyi.

[0012] Further, the belt type flexible brush is composed of a belt and several nylon wire clusters. The nylon wire clusters are evenly distributed on the surface of the belt. The distance between each nylon wire cluster is 3 - 4 cm, and the length of the nylon wire cluster is 15 - 20 cm. Description of the Drawings
