Description

[Detailed description of the invention] The present invention is designed to hold a seedling held by a pair of left and right chopstick-shaped planting claws that surround the front and side surfaces of the seedling, and attach it to the lower end of a rod that can move in and out in the longitudinal direction of the planting claw. The present invention relates to a seedling planting device configured to extrude seedlings using a U-shaped extrusion member provided therein.

In the above-mentioned seedling planting device, conventionally, the side wall of the planting claw and the rod were relatively far apart in side view, and the rod was also relatively small in diameter (for example, -Refer to Publication No. 3719).

Since the planting claws enter the mud surface in an inclined state with the rod side facing downward rather than in a vertical position, the planting claws move in the mud. A large amount of mud and pebbles enters the internal space of the planting claw from the rod side, pushing the leaves and stems of the seedlings out from between the claws, and mud accumulates on the top surface of the U-shaped extrusion member. The mud hangs down on the inner surface of the extrusion member, and the next time the seedlings are removed, the muddy soil prevents the leaves and stems of the seedlings from entering between the nails.

The present invention aims to eliminate the above-mentioned drawbacks by devising the shape of the planted nail.

The characteristic structure of this invention to achieve the above purpose is as follows:
In a posture before pushing out the seedlings in which the extruding member is located relatively above the planting claw, a portion above the side wall of the planting claw than the pushing member is moved from the front wall of the planting claw to the rod portion. The upper part of the side wall is brought close to the rod in a side view, and the diameter of the rod is approximately the same as the inner width interval of the both side walls. That's what I did.

According to the above configuration, as the planting claw moves in the mud, mud from the rod side, that is, mud and pebbles that enter from the opposite side to the direction of movement of the planting claw enters the internal space of the planting claw. The amount of water that can enter is restricted by the rod and side wall. As a result of the above configuration,
Conventionally, pebbles and mud that enter from the opposite side of the planting claw's moving direction clog between the planting claws, and mud that enters the internal space of the planting claw can cause the leaves and stems of the seedlings to become damaged. Mud that has been pushed out between the planting nails or accumulated on the top surface of the U-shaped extrusion member hangs down to the inner surface of the extrusion member, and when the seedlings are taken out, the mud is washed away by the leaves of the seedlings. This prevents the stem from entering between the nails, and allows seedlings to be planted with their leaves and stems in a substantially vertical position.

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 1 to 3, there is a tilted seedling stand 1 that is horizontally reciprocated with a constant stroke, a swinging arm 3 that is pivotably supported in the front-back direction on a planting mission case 2, and A crank arm 4 rotatably supported by the transmission case 2, a planting claw holding case 5 supported in a vertically circulating manner by the swing arm 3 and the crank arm 4, and the case 5. A planting claw 6 supported in a cantilevered manner is provided, and the planting claw 6 is configured to move vertically and cyclically between the lower end of the seedling stand 1 and the mud. A rod 7 is supported in the case 5 in such a manner that the rod 7 can be moved forward and backward in the longitudinal direction of the claw 6 and with a space between the rod 7 and the claw 6 for passing the seedlings, leaves, and stems.
A U-shaped extrusion member 8 for separating the seedlings held by the claws 6 is attached to the protruding end of the
The pushing member 8 is configured to be operated to project toward the tip of the claw when the claw 6 reaches near the bottom dead center, and to be retracted at other times.

In short, the claws 6 take out a seedling equivalent to one plant from the lower end of the seedling placed on the seedling stand 1, and the taken out seedlings are supported by the cooperation of the claws 6 and the push-out member 8. The seedlings are planted by repeatedly carrying the seedlings into the mud, and then repeating the operation of separating the seedlings from the claws 6 using the push-out member 8 in the brought-in state.

The planting claw 6 is composed of a pair of left and right chopstick-shaped planting claws that surround the front and side surfaces of the seedling, and the upper portions 9a, 9a of the side walls 9, 9, that is, the extrusion member 8 is In the posture before pushing out the seedlings, which is located above the attached claw 6, the upper portion 9a of the side wall 9, which is above the pushing member 8, is connected to the rod 7.
In order to eliminate the opening of both lateral sides of the seedling insertion space between the planting claw 6 and the planting claw 6, it is extended to the rod 7 side in a state that closes the front wall 10 of the planting claw 6 to the rod 7 portion. , when viewed from the side, is configured to be close to the rod 7 and overlap, and the diameter of the rod 7 is such that mud from the rod 7 side as the planting claw 6 moves in the mud is used for the seedling insertion. The thickness is approximately the same as the inner width interval of both side walls 9, 9 of the planting nail 6 so as to prevent it from entering the space.

In addition, the lower surface of the extrusion member mounting portion of the rod 7 is formed into an inclined surface S that is located upward as the distance from the claw 6 increases, so that mud can be penetrated without pressing the mud. .

Incidentally, although reference numerals are written in the claims section of the utility model registration for convenience of comparison with the drawings, the present invention is not limited to the structure of the attached drawings by such entry.
