Description

Walnut grafting budding knife

technical field

The present invention relates to a kind of budding knife, the budding knife especially used in walnut grafting process.

background technology

Grafting trees can keep the merit of scion variety, can utilize again the advantageous feature of stock, reaches precocity fruiting, strengthens the ability of cold resistance, drought resistance, disease and insect resistance, can also economic utilization propagating materials, increase nursery stock quantity.In bud grafting process, need to use budding knife to carry out cutting, choose skin, open the steps such as bleeding mouth.The diameter of stock adopted during Studies of Walnut Bud Grafting is 2 ~ 3 centimetres, and the length of side of square sprout tuber is 1 cm.The budding knife sold on the market is now not only heavy, and service efficiency is lower.

" Multi-purpose knife for fruit trees " patent (application number: 98214595.0) disclosed in No. CN2378916Y, Chinese patent, blade inswept, rear end is wide, blade one side is plane, the arcwall face of another side to be radius R 1 be 420-450 millimeter, 5 millimeters, blade thickness, cutting edge is an edge of a knife, and edge grinding is in the one side of band arc, and radius R 2 is 85-95 millimeter, R3 is 60-75 millimeter, have sawtooth at the back side of blade front end, the latter half of radius R 4 at the back side is 80-90 millimeter, long 70 millimeters of knife back saw, blade is fixed on handle, and centre is surrounded by latch closure iron sheet.The weak point of this patent is: blade one side for plane, the arcwall face of another side to be radius R 1 be 420-450 millimeter, 0.5 centimetre, blade thickness, this structure bulky, be unfavorable for the bud sheet that intercepting is smooth, bud grafting efficiency is lower; For the stock that diameter is 2 ~ 3 centimetres, radius R 2 is that the circular arc cutting edge of 85-95 millimeter is peaceful straight, and circular arc cutting edge distance handle of a knife is comparatively far away, can not improve the efficiency of circumgyration incision when carrying out stock crosswise cutting operation; Handle of a knife is circular, and instability when being merely able to pinch with finger with palm when held, can not change position and the angle of blade flexibly, does not therefore reach easy to operate, sensitive, requirement efficiently.

(application number: 200820030817.3), is made up of blade and support " a kind of square grafting knife " patent disclosed in No. CN201138956Y, Chinese patent, and wherein support is cuboid wooden unit; Wherein two complete congruent figures of blade, are fixed on the both sides of support, make to keep certain width between blade, and be parallel to each other; One, another blade polishes, and is fixed on previous insert adjacent, and on the support limit of the aforementioned edge of a knife dorsad; Insert adhesive tape or screw are fixed on support; Square grafting knife can reduce the cutting times of bud grafting, ensure two pieces of epidermis shapes that scion and stock cut just as, reach the contiguity of scion and stock.The weak point of this patent is: parallel blade structure can reduce the cutting times of bud grafting, ensure two pieces of epidermis shapes that scion and stock cut just as, but to make troubles to choosing skin operation; Width when opening bleeding mouth and the width of sprout tuber different, the step of adjustment two parallel blade spacing will be increased, expend time in and reduce bud grafting efficiency.

summary of the invention

Object of the present invention will provide a kind of walnut grafting budding knife exactly, improvement of cutter structure, makes it be more suitable for walnut bud grafting, improves bud grafting efficiency.

In order to achieve the above object, walnut grafting budding knife provided by the invention is made up of handle of a knife and blade, wherein, handle of a knife is manufactured by metal or other hard materials, the cross section of handle of a knife is round rectangle, long 6 ~ 7 centimetres of handle of a knife, handle of a knife is wide 1.5 ~ 1.7 centimetres, thick 0.5 ~ 0.7 centimetre of handle of a knife, handle of a knife too short or too narrow or too thin can affect be affectedly bashful firm, handle of a knife is oversize or too wide or too thick, hinders operation, and this shape convenient operation personnel of handle of a knife pinch with finger instead of with palm when held, easy to operate, sensitive, quick; Blade is long 1.9 ~ 2.1 centimetres, and blade is wide 0.9 ~ 1.1 centimetre, thick 0.09 ~ 0.11 centimetre of blade, and blade is too short or too narrow or too thinly can reduce operating efficiency, and blade is oversize or too wide or too thick, affects the accuracy of operation; Two sides of blade are parallel, are beneficial to and intercept smooth bud sheet fast; One end of blade is fixed on handle of a knife end face, and point of a knife is oval, and this shape of point of a knife can not damage formation layer when carrying out stock longitudinal direction and cutting, choose skin and open the operation of bleeding mouth; One section of edge of a knife shape near handle of a knife is arc-shaped, long 1.3 ~ 1.5 centimetres of circular arc, arc diameter 3.8 ~ 4.2 centimetres, the too short or too little meeting of diameter of circular arc causes blade fully to contact stock appearance cortex and to affect cutting, the flexibility of the oversize or diameter of circular arc too conference impact operation, this circular shape, closer to the cylindrical shape of stock, is convenient to when carrying out stock crosswise cutting operation rotate, not only quick but also can not damage formation layer; The cross section of the edge of a knife is inclined tooth shape shape, i.e. a side of blade deflection blade, and the inclined tooth shape shape of blade is convenient and swift when choosing skin, opening bleeding mouth and intercepting bud sheet.When the invention is employed, operating personnel pinch handle of a knife with finger, change position and the angle of blade flexibly, carry out every bud grafting operation.

Walnut grafting budding knife provided by the invention has positive effect: be made up of handle of a knife and blade, wherein, handle of a knife is manufactured by metal or other hard materials, the cross section of handle of a knife is round rectangle, long 6 ~ 8 centimetres of handle of a knife, handle of a knife is wide 1.5 ~ 1.7 centimetres, thick 0.5 ~ 0.7 centimetre of handle of a knife, long 1.9 ~ 2.1 centimetres of blade, blade is wide 0.9 ~ 1.1 centimetre, thick 0.09 ~ 0.11 centimetre of blade, one end of blade is fixed on handle of a knife end face, point of a knife is oval, one section of edge of a knife shape near handle of a knife is arc-shaped, long 1.3 ~ 1.5 centimetres of circular arc, arc diameter 3.8 ~ 4.2 centimetres, the cross section of the edge of a knife is inclined tooth shape shape, an i.e. side of blade deflection blade, structure is simple, during use, operating personnel pinch handle of a knife with finger, position and the angle that can change blade flexibly carry out every bud grafting operation, neither hindering hand can also reduce cambial damage, greatly improve bud grafting efficiency and survival rate, facts have proved and can improve bud grafting efficiency more than 100%, be applicable to the trees bud grafting at 2.5 cm of walnut bud grafting or other diameter of stock.
