Grafting machine

Abstract

According to the grafting machine, the cutting direction of the grafting machine is changed into the vertical cutting direction, and the cut part of an object and the remaining part do not interfere with each other in the falling direction. The cutting can form a relatively complex incision under the action condition, and particularly, the corresponding cutting edge is provided with an arc-shapedmain edge with the central angle larger than 180 degrees and smaller than or equal to 190 degrees, arc-shaped transition edges continuously connected to the two ends of the arc-shaped main edge in a guiding mode to extend outwards, and straight auxiliary edges connected to the tail ends of the arc-shaped transition edges. Wherein an incision formed by the arc-shaped main blade is mainly used for generating an additional forceps clip, the arc-shaped transition blade roughly forms a flaring structure which is similar to a traditional V-shaped incision and facilitates insertion of a scion, the straight auxiliary blade has better adaptability to the specification and size of a plant, and the whole incision not only is larger in area, but also is provided with a forceps clip part and better incombination firmness. The survival of the scions is favorably ensured.

Description

technical field [0001] The invention relates to a grafting machine. Background technique [0002] Grafting is a kind of traditional asexual vegetative reproduction. During grafting, scion and rootstock should be closely combined to ensure that the scion can survive. Among them, the scion refers to the branches or buds taken from the stable female parent of fruits and vegetables or other crops. The branches or buds taken from the female parent are called Xinshao (which are divided into spring, summer and autumn according to different seasons). There can be 4~5 times a year in the tropics, and the new ones can be used as scions to be grafted after aging. Rootstock refers to the plant that bears the scion when grafting and propagating. The rootstock can be the whole plant, or the root segment or branch segment on the plant. Most of the rootstocks and scions that are suitable for machine grafting need to be grafted in batches, and the shape consistency of rootstock and scion i...

Problems solved by technology

[0003] As mentioned above, there needs to be a close connection between the rootstock and the scion to ensure that the scion can form a living. At present, the interface between the rootstock and the scion is mostly a V-shaped interface. This kind of V-shaped interface is easy to make. In this type of V-shaped interface There are two contact surfaces between the rootstock and the scion, and the two contact surfaces are V-shaped. When artificially grafting, there are not too many requirements for the V-shaped V angle, which is mainly 6-30 degrees to obtain a relatively high survival rate. Therefore, the V angle is generally less than 20 degrees during manual grafting, while the V angle adapted to the grafting machine is mostly 60-70 degrees, the contact surface is relatively small, the clamping effect of the rootstock on the scion is relatively small, and the scion’s Relatively poor bonding firmness

[0004] Chinese patent document CN110383995A discloses a kind of grafting equipment, and it constructs grafting equipment in the mode of streamlined operation, and the scion cutting device that it comprises and rootstock cutting device are arranged on the vertical direction, and two cutting devices are mutually driven There is no interference with the form of movement. In other words, it needs to be equipped with two sets of cutting devices. The synchronization of the movement is not good, and the shape of the incision produced by cutting is not easy to match. Fault-tolerant, but because the flow is equivalent to limiting the scion to move horizontally first, then lift vertically, then move horizontally, and finally align vertically with the rootstock delivered, a series of connection errors will occur, and the alignment accuracy is not easy to guarantee , prone to misalignment between incisions

In view of this, the i
