Grafting device for nursery stock planting

Abstract

The invention discloses a grafting device for nursery stock planting. The device comprises a fixed shell, a working mechanism is arranged on the fixed shell, and the working mechanism comprises threaded rods, limiting plates, a first connecting rod, a spring, a second connecting rod, a mounting protrusion, a cutting blade, an adjusting rod, a barrel, a handle and a connecting block. The threaded rods are connected to the outer circle face of the front side and the outer circle face of the rear side of the fixed shell in a threaded penetrating mode. The ends, extending into the fixed shell, ofthe threaded rods are fixedly connected with the limiting plates. Cutting of multiple connectors can be completed simultaneously, compared with the prior art that connector cutting needs to be conducted one by one, the grafting efficiency is improved, the cutting blade conducts cutting inside the barrel, a user holds the handle with hands, the user does not need to make contact with the blade, andthe operation safety is improved. Besides, the cutting blade can be adjusted through the adjusting rod according to the thickness degree of a rootstock, and the universality of the device is improved.

Description

technical field [0001] The invention relates to the technical field of seedling grafting, in particular to a grafting device for seedling planting. Background technique [0002] Grafting is one of the artificial propagation methods of plants, that is, grafting the branches or buds of one plant to the stem or root of another plant, so that the two parts connected together grow into a complete plant. It is divided into branch grafting and bud grafting. Grafting is carried out by utilizing the healing function of plants after injury. In the production of fruit trees, grafting is not only used to maintain the excellent characteristics of varieties, but also used for early fruiting and overcoming the difficulties of some species that are not easy to reproduce. Disease resistance and immunity, prevention of pests; in addition, the adaptability of the rootstock can be used to expand the cultivation area and improve the yield and quality. [0003] The existing patent (notification ...

AI Technical Summary

Problems solved by technology

[0003] The existing patent (notification number: CN 207692454U) is a rootstock cutting device for olive grafting, which can effectively solve the problems of low cutting efficiency and unsafety of existing rootstocks. The cutting strand and the tip of the second cutting strand are respectively provided with a first clamping wing and a second clamping wing, and a rectangular cavity with an open end is arranged inside the first shearing strand, and the cavity is sequentially provided with Battery storage box, electric push rod and cutter, the electric push rod is fixedly connected with the tail end of the cutter, the cutter is snapped on the adjustment plate, and the adjustment plate is connected with the adjustment knob through the connecting rod

[0004] In the process of realizing the present invention, the inventor found that at least the following problems in the prior art have not been solved: the stock is clamped by the first clamping wing and the second clamping wing in the prior art, and the electric push rod is used to drive the cutter Cutting can effectively reduce the chance of the tool hurting the staff during the rootstock cutting process and improve the safety of use. However, for thicker rootstocks, it is necessary to cut multiple joints on the edge of the end face for grafting. Multiple scions to ensure the success rate of grafting, the existing technology can only cut the joints one by one, the efficiency is low, and the existing technology can not adjust the position of the blade according to the thickness of the rootstock, and the versatility is low
