Description

Detailed Description of the Invention (Field of Industrial Application) The present invention provides a method for planting green onion seedlings by sandwiching them between a pair of left and right rubber disks, and aligning the end surfaces of the roots of the green onions between the two rubber disks. It is a continuous supply system.

(Prior art) Conventionally, as shown in Japanese Patent Publication No. 56-1881, a seedling is wrapped between two tapes in advance, and the ends of the tape wrapped around the seedling are unwound from side to side. At the same time, the seedlings sandwiched between tapes were fed between two rubber discs.

(Problem to be solved by the invention) However, not only does it take a considerable amount of time to wrap the seedlings between two tapes, but it is also difficult to align the end surfaces of the roots of the seedlings. The roots of the seedlings are sandwiched deeply or shallowly between the boards.
The seedlings are planted shallowly in the ground, and the seedlings that are pinched are planted deep in the ground, which has the disadvantage that the planted seedlings do not grow evenly.

The object of the present invention is to improve this drawback, to more efficiently supply seedlings between two rubber disks, and to plant the fungi at the same depth.

(Means for Solving the Problems) To explain the present invention with reference to the embodiment shown in the drawings, "a" is a pair of rubber disks whose upper halves are open to the left and right, and the left and right rubber disks a, below a The outer periphery of the erection shaft 2 is provided so that the terminal end of the transverse conveying belt 1 on which the root of the long leek is placed can be seen on the front outside of the vertical plane of the half part.

Reference numeral 3 denotes a leaf cross-feeding belt on which the leaves of a long leek are placed, which moves parallel to the root cross-feeding belt 1, and the construction shaft 4 at its terminal end extends into the open upper half of one rubber disk a.

The starting end of each transverse belt 1.3 is supported by an erection shaft 5.

61♀Root cross-feed belt This belt rotates perpendicularly to one side of the root cross-feed belt 1. The operator presses the end surface of the root against the belt 6 to cross-feed the roots of the seedling.
Then, place the leaf on the leaf cross-feeding belt 3-''2.

7 is a pressure belt in contact with the upper surface of the root cross-feeding belt 1;
The starting end of the pressure belt 7 faces the end of the root end-face traversing heald 6, and each of these belts 1.3.6.7 moves in synchrony and at the same speed.

Reference numeral 8 denotes a planting depth adjustment plate, which is attached to the back side of the root end face transverse belt 6 so as to be movable forward and backward. (Function) A worker sits on a seat S on the machine, which is moved in the direction of the arrow in Fig. 6 by the engine E, and feeds green onion seedlings one by one, with the roots transversely conveyed onto the belt 1, and the leaves transversely conveyed. belt 3”-,
Then, when the end surfaces of the roots are lined up while pressing against the transverse conveying belt 6, each belt 1, 3, 6, 7 moves in synchrony and at the same speed, and each image is aligned with the end surfaces of the roots and is transversely conveyed by the pressing belt 7. The seedlings are fed between the mutually contacting vertical parts of the rubber discs a which are pressed by the belt 1-1 and whose upper halves are opened left and right along the outer periphery of the erection shaft 2.

In addition, the leaves are moved in the same way as the roots by the transverse conveying belt 3,
It is supplied to the outwardly open upper half of one rubber disk a, and as the rubber disk rotates, it is sandwiched together with the other rubber disk in the radial direction of the rubber disk together with the root. Seedlings are planted vertically as shown in Drawing 1. When the adjustment plate 8 is moved forward toward the root cross-feeding belt 1, the roots of the seedlings are pushed out onto the root cross-feed belt 1, and the rubber disks a and a are held deeply between the roots of the seedlings, so that the seedlings can be planted. The depth is made shallower, and when the adjustment plate 8 is moved back, the planting depth of the seedlings is made deeper.

(Embodiment) Reference numeral 9 denotes a support plate on the back side of the root cross-feeding belt 1, which prevents the belt 1 on which the root is placed from sagging. Reference numeral 10 denotes a leaf tip pedestal mounted parallel to the leaf transverse conveying belt 3.

Reference numeral 11 denotes a support shaft of the left construction shaft 13 of the root pressing belt 7 which is stretched in a triangular shape with the construction shaft 12 as the apex, and a spring is wound around this to enable the construction shaft 13 to slide elastically from side to side. If the roots of the seedlings on the transverse conveying belt 1 are thick, the erection shaft 13 is pushed back by the roots of the seedlings and loosens the pressure belt 7, so that the thick roots are not crushed by the pressure belt 7.

Reference numeral 14 denotes a right-side installation shaft of the pressure belt 7 stretched in a triangular shape, and a drive shaft 1 rotated by the engine E mounted on the aircraft.
5 so that it can rotate freely.

Reference numeral 16 denotes a tightening change gear; as shown in FIG. 1, a speed change change gear 17 consisting of change gears of different diameters is attached to the drive shaft 15; a drive wheel 12a coaxial with the construction shaft 12; and a drive wheel 2a coaxial with the construction shaft 2. and tight change gear 1
A power transmission check 718 is passed over the rack.

The seedling n sandwiched between the left and right rubber disks a and a is the groove cutter 1.
The seedlings are planted vertically into the grooves formed by the grooves 9 as shown by broken lines in FIG.

21 is a V-shaped rod that pushes open the upper half of the rubber disks a, a to the left and right; 22 is a push-opening tool that is inserted under the vertical lower half of the rubber disks a, a; The lower part of the vertical part of the left and right rubber discs is pushed open in order to plant the seedlings that are sandwiched between the vertical lower halves of the rubber disc.

(Effect of the invention) In the present invention, an operator on the machine pushes the root end of the seedling onto the root end cross-feeding belt 6 on two cross-feeding belts 1.3 that move in parallel and at the same speed. When the green onion seedlings are lined up while being pressed against each other, they are gradually transferred to the rubber disk a with the end surfaces of their roots aligned, and are pressed onto the cross-feeding belt 1 by the pressing belt 7. The upper leaf part 3 is also reliably transferred together with the root part, and the end part of the root cross-feeding belt l and the pressing belt 7 which is at the same speed and in contact with this belt is connected to a pair of rubber discs a, a whose upper halves are opened left and right. The root part is securely sandwiched between the vertical parts, and the seedling along with the leaves guided by the root part are sandwiched along the radial direction of the pair of rubber discs with the end surfaces of the roots aligned. , they can be planted perpendicularly to the ground surface and at the same depth, allowing for continuous and efficient planting. Moreover, in the present invention, the planting depth of the seedlings can be freely adjusted by moving the adjustment plate 8 back and forth to push the seedlings onto the root cross-feeding belt 1, which is the root portion of the seedlings, and to move the adjustment plate 8 back and forth.
