Problems solved by technology

[0006] Although the existing picking device can assist manual picking to a certain extent, there are deficiencies in the use process and principle: on the one hand, judging from the arrangement position and direction of the annular blade and the annular sipe, when performing the cutting action, it is necessary to The thumb and forefinger move up and down relative to each other in a parallel state, the cutting force is not strong, it is awkward, it is not easy to exert force, and it is easy to fatigue, which cannot improve the working efficiency; on the other hand, the ring blade and the ring groove The occlusal direction is perpendicular to the plane of the hand, and the purple potato leaf stem is placed in the most natural way between the thumb and forefinger. The direction is also vertical, so the cutting edge and the cut leaf stem are parallel to each other, which is not easy to achieve. Cutting off the stem, the cutting effect is naturally greatly reduced

Embodiment 1

[0023] Such as Figure 2a to Figure 6 As shown, the artificial harvesting device for a stem tip provided in this embodiment includes a matching index finger ring 100 and a thumb ring 200, which are respectively worn on the index finger and thumb of the same hand. When applicable, the index finger naturally bends inwards to form a Roughly horizontal position, the thumb is pressing down on the natural bending of the index finger, and then only need to place the tip of the plant stem to be cut between the two fingers.

[0024] Among them, see Figure 2a and 2b , the index finger ring 100 includes an index finger ring body 101 and a V-shaped sipe 102 arranged on the outer surface of the index finger ring body 101, specifically, the V-shaped sipe 102 can be preferably composed of two parallel triangles 1021 are formed side by side, but not limited thereto. The direction of the V-shaped sipe 102 is parallel to the central axis of the index finger ring body 101; the index finger r...

Embodiment 2

[0028] Such as Figure 2a to Figure 4b As shown, the artificial harvesting device of a kind of stem tip provided by the present embodiment, in the present embodiment, the height of the ridge-shaped cutter body 202 is greater than or equal to the depth of the V-shaped knife groove 102, so that the ridge-shaped cutter body 202 enters and exits The V-shaped sipe 102 is more flexible, which is conducive to bringing better cutting effect with less force, saving labor and high efficiency. The length of the index finger ring body 101 is greater than or equal to the length of the V-shaped knife groove 102, thereby forming a wider protection range on the surface of the finger and further ensuring the safety of the operation process.

Embodiment 3

[0030] Such as Figure 4a and Figure 4b As shown, the artificial harvesting device of a stem tip provided in this embodiment, in this embodiment, at least one of the wear-resistant outer ring and the plastic middle ring is an eccentric circle structure, and the center of the wear-resistant outer ring is directed toward The side away from the V-shaped sipe 102 or the ridge-shaped cutter body 202 is offset, and the center of the plastic middle circle is offset to the side close to the V-shaped sipe 102 or the ridge-shaped cutter body 202; One of the feasible solutions is that the plastic middle ring has an eccentric structure, and it can also be that only the wear-resistant outer ring adopts an eccentric structure, or both the wear-resistant outer ring and the plastic middle ring have an eccentric structure; the pre-achieved effect is the same , are all set eccentrically, so that the wear-resistant outer ring has a larger thickness at the part with V-shaped sipe 102 or ridge-s...

Abstract

The invention discloses a manual stem tip harvesting device. The manual stem tip harvesting device comprises an index finger ring and a thumb ring which are used in cooperation, the index finger ringcomprises an index finger ring body and a V-shaped cutter groove formed on an outer surface of the index finger ring body, and a trend of the V-shaped cutter groove is parallel to a central axis of the index finger ring body; the thumb ring comprises a thumb ring body and a ridge-shaped cutter body arranged on an outer surface of the thumb ring body, and a trend of the ridge-shaped cutter body anda cutting edge at a top end of the ridge-shaped cutter body are both perpendicular to a central axis of the thumb ring body; and the index finger ring body and the thumb ring body are each formed byconnecting a wear-resisting outer ring, a plastic middle ring and a flexible inner ring, the V-shaped cutter groove and the ridge-shaped cutter body are both fixedly connected to the wear-resisting outer ring and matched in shape, and an overall length of the V-shaped cutter groove is larger than or equal to a length of the ridge-shaped cutter body. Aiming at characteristics of stems and leaves, the manual stem tip harvesting device has a reasonable structural design, a fast cutting, a good effect and a high harvesting efficiency.

Description

technical field [0001] The invention relates to a tool for manual harvesting, in particular to a device for manual harvesting of stem tips, which is suitable for picking tender leaves of stem tips such as sweet potato stem tips. Background technique [0002] The stem tip is a section of tender stem and tender leaves at the top of the plant branches and tendrils. It is a mixture of tender leaves and tender stems. Therefore, it is small and tender. It often needs to be carefully picked by hand. If you do it by hand, that is, if you pinch it with your nails, the stem tip The sap can easily damage the skin; if harvesting with tools such as scissors, the efficiency is low and it is not safe enough. [0003] As a representative of the need for stem tip harvesting, the tender leaves of the sweet potato stem tip have the function of nutrition and health care: the 10 cm long tender stem and tender leaves at the top of the sweet potato vine are called the sweet potato stem tip. This p...
