Abstract

There is disclosed an immature plant grafting apparatus capable of seizing en bloc a plurality of saplings raised in array irrespective of a scatter in diameters of stems without requiring hand works and damaging the saplings and of grafting the saplings at a remarkably high efficiency but at low costs. The grafting apparatus has a plurality of induction plates (9a and 9b) formed with a plurality of induction grooves (10) open to seizing surfaces, corresponding to the number of saplings (3a and 3b) to be seized and their positions, induction plates so attached to upper and lower surfaces of one of a pair of seizing devices (4 and 5) as to protrude from the seizing surfaces, and buffer members (13) projecting from the seizing surfaces of the other seizing device so that each buffer member is fitted in between the pair of induction plates.

Claims9

Dependent claims

An apparatus for grafting immature plants, comprising:

a pair of seizing means for simultaneously seizing a plurality of saplings raised in arrays;
cutting tools to said plurality of saplings seized by said seizing means with upper portions of said seizing means to obtain stocks but with lower portions thereof to obtain scions, respectively;
and
a means for superposing said seizing means which seizes a plurality of cut stocks obtained by removing the upper parts of said saplings on said seizing means which seizes said cut scions obtained by removing the lower parts thereof and cut faces of said stocks and of said scions are fitted together, wherein upper and lower surfaces of one of said pair of seizing means are provided with plural pairs of induction plates chased with a plurality of induction grooves open to the seizing surface, corresponding to a number of seized saplings and to their positions, said induction plates being protruded from the seizing surface, and with buffer members protruded on the seizing surface of said other seizing means so that each of said buffer members is fitted in between a pair of said induction plates.

1 more element

An apparatus for grafting immature plants, comprising:

a first conveyor for sequentially carrying a plurality of stock raising boxes;
a second conveyor, laid in parallel with said first conveyor, for sequentially carrying a plurality of spicate segment raising boxes;
seizing, cutting and grafting stations, arranged sequentially from an upstream side in the carrying direction of said two conveyors;
a frame releasing station provided in continuation from said grafting station on the lowest stream side in the carrying direction of said first conveyor;
seizing means, mounted on said respective seizing stations of said first and second conveyors, for seizing said saplings raised in array within said sapling raising boxes by use of an induction seizing member and a support seizing member and fixing said seizing members onto said sapling raising boxes in a state where said seizing members seize said saplings;
a stock cutting means, mounted on said cutting station of said first conveyor, for cutting said saplings catered for stocks with upper portions of its seizing unit;
a scion cutting means, mounted on said cutting station of said second conveyor, for cutting said saplings catered for scions with lower portions of said seizing unit thereof;
a grafting means, mounted on said grafting station of said first conveyor, for fixedly superposing said scion saplings cut and separated from the lower parts of said saplings by the lower portions of said seizing unit while being seized by said seizing members on a sapling raising box for stocks obtained by cutting the upper parts of said saplings with the upper portions of said seizing unit, the lower parts thereof being seized by said seizing members;
and
a frame releasing means, mounted on said frame releasing station, for taking off said seizing members which seize said saplings after completely grafting said saplings.
