Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is for continuously feeding green onions between two rubber disks when planting the green onion seedlings by sandwiching them between the two rubber disks. It is.

(Prior art) It is extremely inefficient for workers to manually feed green onion seedlings one by one between two rubber discs.
As shown in Japanese Patent Publication No. 56-1881, a seedling is wrapped between two pieces of tape in advance, and while unwinding the seedling-wrapping tape from side to side, the seedling sandwiched between the tapes is placed between two rubber discs. was supplying.

(Problems to be Solved by the Invention) However, not only does it take a considerable amount of time to wrap the seedlings between two pieces of tape, but it is also difficult to attach the seedling wrapping tape wrapped with the tape that holds the seedlings to the green onion transplanter. It also requires a lot of effort.

Therefore, an object of the present invention is to more efficiently, continuously and reliably supply seedlings between two rubber disks along the radial direction of the rubber disks.

(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, under a are The outer periphery of the construction ring 2 at the end of the conveyor belt 1 on which the root of the long onion is placed can be seen on the front outside of the vertical plane of the half part.

Reference numeral 3 denotes a conveyor belt on which the leaves of a long leek are placed, which moves parallel to and at the same speed as the conveyor belt 1, and a construction ring 4 at the end thereof extends over the open upper half of one rubber disk a.

Reference numeral 5 denotes a pressure belt that touches the upper surface of the conveyor belt 1 at the root and moves at the same speed as the belt, which is installed in a substantially triangular shape on the construction wheels 6, 7, and 8, and the terminal end of the pressure belt 5 touches the root of the construction ring 2 on the outer periphery. It overlaps the terminal end of the conveyor belt 1 and extends along with the belt 1 to the front outside of the vertical plane of the lower half of the left and right rubber disks a, a.

9 is a construction ring at the starting end of belts 1 and 3. Reference numeral 10 denotes a support plate on the back side of the root conveyor belt 1 and the leaf conveyor belt 3, and the tips of a plurality of leaf springs 11 attached to this support plate elastically support the back side of the root conveyor belt 11 between the construction wheels 6 and 2. To support.

(Function) A worker sits on the seat S on the aircraft, which is moving in the direction of the arrow in Figure 7 by the engine E, and plants a green onion seedling.
One by one, place the roots on belt 1 and the leaves on belt 3.
When the conveyor belts 1 and 3 are arranged perpendicularly to the belts 1 and 3 on the top, the conveyor belts 1 and 3 move at the same speed while being supported by the support plate 10 to convey the seedlings, and the roots are pressed onto the belt 1 by the pressure belt 5. At the same time, the roots of the seedlings are fed along the outer periphery of the construction ring 2 between the mutually contacting vertical surfaces of rubber disks whose upper halves are opened left and right.

In addition, the leaf part moves in the same way as the root part by the conveyor belt 3, is supplied to the outwardly open upper half of one rubber disk a, and is connected to the other rubber disk as the rubber disk rotates. The seedlings n are sandwiched together with their roots and planted vertically as shown in the front view of FIG.

Therefore, the roots of the seedlings sandwiched between the upper and lower belts 5, 1 between the construction ring 6 at the starting end of the pressure belt 5 and the construction ring 2 at the terminal end of the root transport belt 1 are located at multiple locations on the back side of the root transport belt 1. A multi-piece leaf spring 1
Since it is elastically supported by the tip of belt 1, both thick and thin roots can be pressed from below by the leaf spring.
It moves while being pressed in close contact with the pressing belt 5.

(Example) Reference numeral 12 denotes a leaf tip pedestal attached in parallel to the leaf conveying belt 3, and its starting and ending ends are slightly curved downward.

Reference numeral 13 denotes a root end surface conveying belt that rotates perpendicularly to one side of the root conveying belt 1, and the end surfaces of the roots pressed against this belt are evenly aligned to keep the planting depth of the seedlings constant.

Reference numeral 14 designates the support shaft of the construction wheel 6, which is wound with a spring so that the construction wheel 6 can slide elastically back and forth. The construction wheel 6 moves backward and the pressure belt 5
Since the belt 5 is loosened, the thick root portion is not crushed by the pressing belt 5.

Reference numeral 15 designates a plurality of transmission chain gears with different diameters that are fixed to the drive shaft 16 of the rubber disc a so that their positions can be changed, and as shown in FIG. 18
A chain 20 is bridged between the construction wheel 2 and the coaxial chain gear 19, and by replacing the chain 20 with the transmission chain gear 15, the rotational speed of the construction wheels 2 and 8 is changed, and the rotational speed of the construction wheels 2 and 8 is changed. By changing the number of seedlings sent in, the planting interval of seedlings can be freely adjusted.

However, the construction wheel 7 is fitted onto the drive shaft 16 so as to freely rotate.

The seedling n sandwiched between the left and right rubber discs is planted vertically into the cut groove formed by the groove cutter 21 as shown by the broken line in Figure 1, and then is stabilized by being covered with soil using the soil hooker 22. do.

23 is a V-shaped rod that pushes open the upper half of the rubber disks a and a to the left and right. Reference numeral 24 denotes a device for pushing open a pair of rubber disks at the point of contact with the ground surface in order to plant the seedlings sandwiched between the vertical lower halves of the rubber disks a, a.

(Effects of the Invention) In the present invention, green onion seedlings arranged perpendicularly on the two conveyor belts 1 and 3 that move in parallel at the same speed are supported by the support plate 10 and gradually transferred toward the rubber disk. At the same time, the roots are pressed onto the conveyor belt 1 by the pressure belt 5 which also moves at the same speed, so that the leaves are reliably conveyed perpendicularly to each belt 1, 3, 5 together with the leaves on the conveyor belt 3. The terminal end of the root conveyor belt 1 and the pressure belt 5 in contact with it is a pair of rubber disks a with the upper half open left and right,
Since it extends forward and outward of the vertical part of a, the roots are surely sandwiched between the vertical parts, and together with the long leaves of the seedling guided by the roots, they are precisely sandwiched along the radial direction of the pair of rubber discs, so that the roots are firmly sandwiched between the vertical parts and the ground surface. It can be planted vertically and continuously in a short period of time. Furthermore, in the present invention, the roots of the seedlings between the construction ring 6 at the starting end of the pressing belt 5 and the construction ring 2 at the terminal end of the root conveying belt 1 are elastically supported at multiple locations on the back side of the belt 1 by the leaf springs 11. The thin root adjacent to the thick root is loosely sandwiched between the upper and lower belts 5, 1, and the two rubber disks intersect diagonally rather than perpendicularly to these belts 5, 1. This produces the effect that the seeds are supplied obliquely to the radial direction between a and a, and there is no risk of them being planted tilting forward or backward.

If the operator rides on the machine and feeds the seedlings one by one between the rubber discs, it will take 13 hours to transplant each 10 acres.

In addition, in the case of the conventional seedling wrapping tape that wraps the seedlings between two pieces of tape, it takes 7 hours to wrap the seedlings in the tape per 10 ares, and then 2 hours to transplant, for a total of 9 hours. It takes.

However, the transplanting time according to the present invention is only 5 hours per 10 ares, and moreover, the seedlings can be reliably planted perpendicular to the ground surface.
