Abstract

The utility model relates to a special graft device for split graft, which is a special tool designed for cutting out standard scions and is particularly suitable for flowers, fruit trees, the graft for nursery stock for a forest tree industry and top graft change head graft. The utility model is characterized in that cutting scion can be conducted successfully once. During cutting, two tool rods 4 of the graft device move forward in two T-shaped orbit grooves at the same time, and two tool blades 3 are made to cut scions at the same time. The cutting scion is improved six times than a conventional method, survival rate is high, the utility model is suitable for cutting scions with different thickness, and the tool rods 4 and the tool blades 3 can be changed.

Description

Grafting device for split grafiting

The utility model relates to the special-purpose grafting device of a kind of cleft grafting, and the big tree reconfiguration of suitable especially gardening, gardens industry changes head and grows seedlings grafting and the specific purpose tool of the standard that the cuts scion that designs.

Before the utility model, adopt cutter to cut the scion method mostly.It is nonstandard that cutter is cut fringe, and efficient is low, the cutting face injustice, and the scion survival rate is low, and easily hinders operator's hand.How existing DST-15 type easily hinders the phloem and the cambium of bad scion with grafting device cutting scion, bevel is more coarse, no thickness face, cause scion insertion stock after fastness poor.

At the problems referred to above, the utility model provides a kind of usefulness two cuttves to cut scion simultaneously, and cutting speed is fast, the scion standard of cutting out, and the scion wedgewise, the long 3-4cm of bevel, the cutting face is level and smooth, and the phloem of scion and the cell injures and deaths in the cambium are few.Scion body after the cutting is seen accompanying drawing two.

Below in conjunction with description of drawings embodiment of the present utility model.

The utility model is formed by driving and cut two parts.Drive part is by main handle 9, secondary handle 8, hinge pin 7, connecting rod 6, little pin 12, spring 10, connecting lever 11 compositions such as grade.Cutting tip is by fringe seat 1, plugged ear hole 14, blade 3, knife bar 4, screw 15, knife rest 2, screw 13, sliding pin 5, sliding pin groove A, compositions such as crank-guide way B.The each several part composition sees the main accompanying drawing one of looking for details.

The detailed connection and the special construction of each part mentioned above are described below:

Knife rest 2 forms for metal material turning.Referring to vertical view accompanying drawing four, T type track of system is respectively milled in the two sides of knife rest 2; The oblique angle of two track chutes is 11-15 °, and with last plane included angle be 5 °; In the middle of T type groove, sentence and mill a chute A who connects down again; Mill crank-guide way B vertical of system again at knife rest 2 with A.Knife bar 4 is made for metal material, and machine is made the T font, matches with track slot; Knife bar 4 one ends are fixed with screw 15 and are gone up carbide alloy or carbon element tool blades 3, and blade 3 sharp end are worn into monocline face straight line sword; Knife bar 4 drilled in middle one circular hole penetrates garden column sliding pin 5, and it is hinged with an end of connecting rod 6 that sliding pin 5 is passed in the center groove of knife rest 2 again; The other end of connecting rod 6 is articulated in by pin 12 on the force of connecting lever 11 of secondary handle 8; The swing of connecting lever 1 arc can drive knife bar 4, advances and retreat in the two pass rail of knife rest 2.Hinge pin 7 is linked together main handle 9 with secondary handle 8, form the relative arc swing of two handles 8,9.Unlatching after the compression of handle 8,9 is finished by the compression of the chip on the appropriate location that is contained in the handle 8,9 spring 10.One end of knife rest 2 is drilled with pin joint 12 an end Joint outward of three screw holes and main handle 9.Top (the seeing the accompanying drawing Front view 1) of knife rest 2 is equipped with fringe seat 1; Fringe seat 1 is for turning font (seeing the accompanying drawing Front view 1); Turn the font minor face headblock or ebonite headblock are housed.Have the elongated slot ditch in the middle of fringe seat 1 top,, reach the purpose of blade 3 cutting scion so that connecting rod 6 reciprocally swingings drive knife bar 4 and move forward and backward; Fringe seat 1 offers the elongated slot ditch near the connecting lever center and knife rest 2 top crank-guide way B match.The elongated slot ditch both sides of fringe seat 1 are bored and are milled two grooves, available screw 13, and fixedly fringe seat 1 is on knife rest 2; By three sizes that screw 13 can be regulated fringe seat and knife rest on the knife rest 2, to adapt to the cutting of thickness scion.(seeing accompanying drawing upward view three for details).

The utility model specific embodiment is as follows:

The oblique angle of the two sides T type track slot of the utility model knife rest 2 is 11 °, with the angle on last plane be 5 °, knife bar 4 one ends are carbon tool steel with screw 15 fixing blade materials; The shape minor face that turns of fringe seat 1 is equipped with headblock.

During use, main handle 9 is down, and secondary handle 8 is last, two handles 8,9 open-shaped attitude under the effect of spring 10.This moment is with scion dotted portion from 14(accompanying drawing one front view of plugged ear hole) in insert forward, when directing reach fringe seat 1, the major and minor handle 9,8 of holding with a firm grip, connecting lever 11 is swung forward, impels connecting rod 6, drive sliding pin 5, force two knife bars 4, move forward (be in accompanying drawing one front view lock-joint move to P ' point) along two tracks on the knife rest 2 respectively, run on the fringe seat up to two blades 3 from the P point, cutting finishes, and can take out scion.Two handles 8,9 can reset backward.

The utility model is implemented after application in practice can once be finished the cutting scion, and work efficiency can improve 6 times, cutting scion standard, and the thickness scion all can be used, and the scion graft survival rate reaches more than 92%.Be seedling grafting and grafting high and changing head graftings such as present gardening, gardens, comparatively desirable grafting tool.

Claims

1, a kind of special-purpose grafting device of cleft grafting that is used for is made up of main handle 9, secondary handle 8, fringe seat 1, knife rest 2, and its feature has main handle 9 front ends to settle knife rest 2; The double blade 3 that can slide synchronously at two trapped orbits that secondary handle 8 fronts are mounted with that connecting rod drives.
