Description
Technical Field
The utility model relates to an instrument of artifical collection usefulness, especially an artifical collection device of stem tip is applicable to the picking of the tender leaf of stem tip such as sweet potato stem tip.
Background
The stem tip is a section of tender stem and tender leaf at the top end of the plant branch and vine, and is a mixture of tender leaves and tender stems, so that the stem tip is small in size and tender, the stem tip is usually manually picked carefully, and the skin is easily injured by free hands, namely when the nail is nipped; however, when harvesting is performed with a tool such as scissors, the efficiency is low and the harvesting is not safe enough.
As a representative requiring stem tip harvesting, the tender leaves of the stem tip of the sweet potato have the functions of nutrition and health care: the tender stem and tender leaf of the top 10 cm long of the sweet potato vine is called the sweet potato stem tip, the part of tissue is fresh and tender, the nutrients are concentrated, the nutritive value is high, and the sweet potato vine is a good item in vegetables according to the nutritional ingredients; secondly, the stem tip of the sweet potato has the function of diuresis when being eaten as a vegetable and is a good vegetable for patients with hypertension.
In conclusion, the sweet potato stem and leaf vegetable is produced by using young stems and leaves, has tender tissue and high water content, is easy to wither and dehydrate, and is required to keep a higher product grade, so that the sweet potato stem and leaf vegetable is harvested in time, and an efficient, convenient, safe and protective harvesting tool is urgently needed.
In order to solve the above problems, as shown in fig. 1, a known purple sweet potato leaf picking device is disclosed to be composed of an annular blade 1, a fixing ring 2, a picking glove 3 and a squeezing lantern ring 4, wherein a picking glove body is woven by cotton yarn, a thumb and a forefinger of the picking glove are made of silica gel, the fixing ring is arranged on the outer side of the thumb of the picking glove, the annular blade is arranged on the fixing ring, the squeezing lantern ring is sleeved on the outer side of the forefinger of the picking glove, and a plurality of annular cutter grooves are uniformly formed on the outer side of the squeezing lantern ring. When the purple sweet potato leaf and stem picking glove is used, firstly, the picking glove is sleeved on a hand, then the purple sweet potato leaf and stem to be picked are placed between a thumb and a forefinger, the thumb and the forefinger of the picking glove are closed, the outer side of the thumb of the picking glove is provided with the annular blade on the fixing ring, the purple sweet potato leaf and stem can be extruded, and the annular blade cuts off the purple sweet potato leaf and stem by the closing force.
Although the existing picking device can assist manual picking to a certain extent, the using process and the principle are not enough: on one hand, according to the arrangement positions and the directions of the annular blade and the annular cutter groove, when cutting is carried out, a thumb and a forefinger are required to move up and down relatively in a parallel state, the cutting force is not large, the thumb and the forefinger are also quite difficult, the thumb and the forefinger are not convenient to apply force, and the thumb and the forefinger are easy to fatigue and cannot improve the operation efficiency well; on the other hand, the occlusion direction of the annular blade and the annular cutter groove is vertical to the plane of the hand, and the trend of the purple sweet potato leaves and stems after being placed between the thumb and the forefinger in the most natural mode is also vertical, so that the cutting edges are parallel to the cut leaves and stems, the leaves and stems are not conveniently cut off, and the cutting effect is naturally reduced.
Disclosure of Invention
In order to overcome the above-mentioned not enough of prior art, the utility model provides an artifical harvesting device of stem tip, the device is to the stem leaf characteristics, and structural design is reasonable, cuts fast effectually, and it is efficient to gather.
The utility model provides a technical scheme that its technical problem adopted is: the index finger ring comprises an index finger ring body and a V-shaped cutter groove arranged on the outer surface of the index finger ring body, the direction of the V-shaped cutter groove is parallel to the central axis of the index finger ring body, the thumb ring comprises a thumb ring body and a ridge-shaped cutter body arranged on the outer surface of the thumb ring body, and the direction of the ridge-shaped cutter body and a cutting edge at the top end of the ridge-shaped cutter body are perpendicular to the central axis of the thumb ring body; the index finger ring body and the thumb ring body are formed by connecting three layers of structures including a wear-resistant outer ring, a plastic middle ring and a flexible inner ring, the V-shaped cutter groove and the ridge-shaped cutter body are fixedly connected to the wear-resistant outer ring, the shapes of the V-shaped cutter groove and the ridge-shaped cutter body are matched, and the overall length of the V-shaped cutter groove is greater than or equal to the length of the ridge-shaped cutter body.
