Description

[Detailed explanation of the idea] This invention relates to a portable rice transplanter.

Generally, when rice transplanting is carried out using a multi-row rice transplanter, unplanted portions of seedlings occur at the ridges and headlands of the rice field, that is, where the rice transplanter enters the rice field.

Conventionally, seedlings have been supplementally planted in the unplanted areas by inputting seedlings, but such supplementary planting is a half-hearted job and is extremely troublesome for workers who are not accustomed to manual planting. It has become a thing.

The present invention was devised in view of the above-mentioned circumstances, and its purpose is to provide a portable rice transplanter that can replant seedlings in an extremely simple and comfortable posture, and that can reliably replant seedlings. That is.

Therefore, the configuration of the present invention is such that a horizontally extending frame is fixed to the lower part of the seedling stand with the lower end open, handles are provided on both sides of the frame in the length direction, and handles are provided on both sides of the frame in the length direction, and handles are provided on both sides of the frame in the longitudinal direction. A hopper with a chute is installed at a position, a movable body is supported on the frame so as to be movable in the length direction of the frame, and a seedling receiving plate is provided on the movable body to receive the seedlings fed from the seedling platform. A seedling holder is rotatably supported, and includes a rotary blade for cutting the seedlings received on the seedling receiving plate and a feeder for feeding the seedlings cut by the rotary blade to the hopper. , is equipped with a seedling planting tool that drops the chute, and when supplementary planting of seedlings is carried out, the rice transplanter is carried by grasping the handle, and the seedlings fed from the seedling platform to the seedling receiving plate are The seedlings are cut by the rotary blade of the seedling holder, forcibly fed to the hopper by the feeder, dropped from the hopper downwards through the chute, and then planted in the soil of the paddy field by the planting tool. It's just like I said.

In the figure, reference numeral 31 denotes a shoulder strap hung between the upper part of the seedling stand 1 and the upper part of the chute 6. By hanging the strap 31 on the shoulder and grasping each of the handles 5 by hand, rice planting can be carried out. I carry a machine with me when I do rice planting work.

The rice transplanter according to the present invention is constructed as described above, and when supplementary planting seedlings on the edge of a paddy field or on a headland, the shoulder strap 31 is hung over the shoulder as shown in Fig. 1, and each handle is 5 in hand and carry the rice transplanter.

The movable body 8 is moved from one side of the seedling platform 1 to the other side by the rope 14 connected to the recoil starter 15, and as the movable body 8 moves, the seedling handle 10 is rotated. The seedling handle 10 cuts the seedlings supplied from the seedling platform 1 onto the seedling receiving plate 9 and forcibly sends the cut seedlings to the hopper 7.

That is, when the seedling handle 10 starts cutting the seedlings, as shown in FIG. Then, from this state, as shown in FIG. When the seedling handle 10 is rotated, the feeder 10c of the seedling handle 10 comes into contact with the cut seedling, as shown in FIG. Thus, the cut seedlings are forcibly sent out.

Then, the cut seedlings are placed in the notch 9 of the seedling receiving plate 9.
It is supplied from a to the hopper 7, and is dropped downward from the hopper 7 via the chute 6.

In this state, the planting claw 25 provided at a lower position of the chute 6 is swung via the operating arm 23 by operating the operating lever 28.

This swinging of the planting claw 25 is caused by the operation arm 23
The tip of the planting claw 25 contacts the side of the seedling held by the holding device 20 made of a plurality of wire rods 20a, and the seedling is moved diagonally downward from the holding device 20. The seedling is pushed out, and the pressing action of the planting claw 25 causes the seedling to be planted in the soil of the paddy field.

As explained above, in the portable rice transplanter of the present invention, a horizontally extending frame is provided at the bottom of the seedling platform, handles are formed on both sides of the frame, and a hopper with a chute is provided below the seedling platform. At the same time, a movable body is movably supported on the frame, and the movable body is provided with a seedling holder and a seedling receiving plate having a rotary blade and a feeding body, and a planting tool is provided at the bottom of the chute. Then, the seedlings sent from the seedling stand are received by the seedling receiving plate, the seedlings are cut by the rotary blade as the seedling handle rotates, and the seedlings are forcibly fed to the hopper by the feeding body. Since the seedlings were dropped from the hopper to the lower part of the chute and planted into the soil of the paddy field using the planting tool, supplementary planting work of seedlings to the ridges or headlands of the paddy field was carried out using the rice transplanter. This can be done extremely simply and easily, and since the seedlings cut by the rotary blade of the seedling handler are forcibly fed to the hopper by the feeder, the seedlings can be taken out from the seedling receiving plate to the hopper. This allowed us to reliably perform the supplementary planting of seedlings.
