Abstract

There is disclosed an automatic vegetable grafting machine for vegetable grafting. Its stake clamp, which is on the operating platform, is aligned with the center of the graft clamp. The graft clamp's two explorators positions can be adjusted according to the sprout size; one leaf of stake sprout is relied to the exploratory, and scion stalk is relied to the exploratory and is a little bent. The stake and the graft incision fold automatically because of the two knives relative positions on knife-carrier slide and the graft scion bending. Wherein, compression lever and support swing link are separately joined with frame by means of gemels; the stake clamp swing link and the graft clamp swing link are contacted with cam and are joined with the support by means of gemels, and control opening or shutting of the stake and the graft incision and up-or-down movement of the lifter and the knife carrier. After cutting, the stake and the graft incision ascend along the stake and the scion until the graft stalk is unbend and automatically fold with the stake sprout incision, then the stake clamp and the graft clamp open and graft is completed. The machine has simple structure and high work efficiency of 600 trees per hour.

Description

Automatic grafting machine for vegetable

Affiliated technical field

The present invention relates to a kind of machine that is used to carry out vegetable grafting, especially can make by the stock of grafting and scion otch and aim at automatically, thus the survival rate and the operating efficiency of raising vegetable grafting.

Background technology

The conventional method of vegetable grafting is: when rootstock seedling and scion seedling also have only two cotyledons, cut growing point and a slice cotyledon of rootstock seedling, stay a slice cotyledon and rhizome, otch inclined-plane at 45; Again the scion seedling is cut the Lower Half rhizome for oblique 45 °, scion otch and stock cut alignment are pasted together, clip with Grafting clip then, plant in the soil.Because the grafting action is complicated, the vegetable grafting machine construction complexity of domestic and international research cost an arm and a leg, and the grafting effect is undesirable, is not suitable for China's actual conditions at present.Most of vegetables base of China and vegetable grower family grafting vegetables are all adopted manually and finish, time-consuming, the effort of artificial grafting vegetables, specification requirement height.The peasant is badly in need of a kind of simple in structure, and cheap, machine that be suitable for replaces the work of artificial vegetable grafting.

Summary of the invention

For overcoming time-consuming, the effort of manual vegetable grafting, the specification requirement height, and existing machine construction complexity costs an arm and a leg, and is not suitable for China's actual conditions, and the unfavorable deficiency of grafting effect, the invention provides a kind of automatic grafting machine for vegetable, it is simple in structure, and grafting is effective.

The present invention solves the technical scheme that its technical problem takes: movable stock clamp and scion folder is housed on the workbench, and stock clamp and scion folder center overlap in alignment; Fixing stock pattern and scion pattern are arranged.Rootstock seedling is put on the stock clamp, and a slice cotyledon of rootstock seedling leans against on the stock pattern; The scion seedling is put on the scion folder, and the bottom of scion seedling leans against on the scion pattern, the rhizome slight curvature.The position of stock pattern and scion pattern can be according to the size adjustment of rootstock seedling and scion seedling.Two cutting knifes are housed on the square tool post slide block on the workbench, and two cutting knifes are at an angle contour, and two cutting knife mutual alignments are adjustable, satisfy a slice cotyledon only excise rootstock seedling and growing point and and the lower portion of the stem of scion seedling; When stretching after scion is cut rhizome, its otch just in time closes up with the stock otch; Utilize the crooked deformability of two cutting knife relative positions and scion seedling that stock is aimed at automatically with the scion otch.Three forks, a depression bar and a cam are set in the machine.In three forks: the bearing fork links to each other with frame with hinge, and the stock clamp fork links to each other with the bearing fork with hinge with scion folder fork, and bearing and bearing fork are connected with screw, have spring to prop stock clamp and fringe wood clamp on the bearing; Three forks all keep in touch with cam, folding, rising, the decline of controlled stock clamp and scion folder; Depression bar links to each other with frame with hinge, and one of depression bar and cam keep in touch, and the other end is pressed on the knife rest slide block, and the control cutting knife rises, descends, and finishes the action of cutting rootstock seedling and scion seedling.Stock clamp and scion folder clip stock and scion rising respectively after cutting knife is rootstock seedling and the cut-out of scion seedling, rise to the height above stock pattern and scion seedling pattern.Scion this moment seedling cane reverts to straight line, and otch aligns with the rootstock seedling otch automatically.Manually clamp stock and scion cutting part with Grafting clip then, grafting is finished, and can plant.

The invention has the beneficial effects as follows: utilize two cutting knife relative positions and by the crooked deformability of grafting stock is aimed at automatically with the scion otch, operation principle is simple.Stock clamp, scion folder and two cutting knifes can only drive with a cam, and the machine drive path is short, and is simple in structure.Operating efficiency be 600 strains/hour.

Embodiment

In Fig. 1, cutting knife (7), (8) during the work beginning on the knife bar (6) of knife rest (1) are in workbench (2) top, the rise of cam (15) contacts with scion folder fork (14) with stock clamp fork (11), stock clamp fork and scion folder fork and relative the opening of bearing fork (13), spring (12) is in compression position, and stock clamp (9) and scion folder (10) all are open.

In Fig. 2, there are spring (22), (23) to prop stock clamp and fringe wood clamp with the bearing fork with on the bearing (16) that is connected, can clamp rootstock seedling (18) and scion seedling (17); When the stock clamp fork that links to each other with the bearing fork with hinge and fringe wood clamp fork and bearing fork produce relative rotation, but dead spring opens stock clamp and fringe wood clamp.

In Fig. 3, operating personnel are put into rootstock seedling on the stock clamp, and a slice cotyledon of rootstock seedling is abutted against on the stock pattern (19), the cam rotation, and the stock clamp fork contacts with the cam backhaul, and the stock clamp closure has been clamped rootstock seedling under the effect of spring (22); The operative employee is put into the scion seedling on the scion folder again, the bottom rhizome of scion seedling is abutted against on the scion seedling pattern (20), and scion seedling stem slight curvature, cam rotate to scion folder fork when contacting with the cam backhaul, the scion folder is also closed under the effect of spring (23), clamps and has connect the scion seedling.Cam continues rotation, when depression bar (3) contacts with the cam rise, drives slide block (4) and moves down, and two cutting knifes adorning on the slide block cut rootstock seedling and fringe wood seedling simultaneously.Cutter location makes a slice cotyledon and the growing point of rootstock seedling cut, stays a slice cotyledon and rhizome; Rhizome excision in scion seedling bottom stays the stem on top and cotyledon, growing point.When cam rotates to depression bar when contacting with the cam backhaul, rise at the effect sliding block of spring (5), cutting knife is return.When the bearing fork contacts with the cam rise, the bearing fork presss from both sides the height that rises to above stock pattern and scion seedling pattern together with stock clamp that clips stock and scion on bearing and the bearing and scion, scion seedling stem recovers to stretch its cut alignment stock otch.This moment, operating personnel clamped the cutting part of stock and scion with Grafting clip (21), and two otch close up.The stock clamp fork contacts with the cam rise with scion folder fork simultaneously then, the compression spring, and stock clamp and scion folder open simultaneously, and artificial the taking-up clamped the Grafting clip of stock and scion, and grafting is finished, and can plant.
