Abstract

PURPOSE:To open a transplantation hole having short length in longitudinal direction by placing a hole-opening tool in a specific state and opening a transplantation hole at a position to transplant a seedling with a seedling planting rod. CONSTITUTION:A transplantation hole is opened with a hole-opening tool 14 at a position where a seedling is to be transplanted with a seedling planting rod 7 circulating along a vertically extended elliptic orbit A. The tool 14 is attached to a lateral shaft 16 near the ground through a short arm 15. The hole-opening tool is rotated by the pushing or pulling action of the rod 27 in vertical direction to open a transplantation hole having short length in longitudinal direction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention is used for a seedling transplanter for field operation.

[0002]

2. Description of the Related Art In a seedling transplanter for field operation, since the ground for transplanting seedlings is harder than the mud in paddy fields, grooves or holes are formed in advance at the positions for transplanting seedlings. The present invention proposes a device in which a hole making tool is mounted in a narrow space, short transplant holes are formed in the front and rear, and backfilling after transplanting seedlings is easy.

[0003]

In order to achieve the above-mentioned object, the present invention has an elliptical orbit A which is long in the vertical direction when viewed from the side.
It is equipped with a seedling planting rod 7 for swiveling to take out the seedlings on the seedling mounting table 6 and transplanting them to the ground below, and a hole forming tool 14 for making a transplanting hole at a position where the seedling planting rod 7 transplants seedlings. The hole making tool 14 is attached to the horizontal shaft 16 near the ground by a short arm 15 and is provided so as to be rotated by pushing and pulling the rod 27 in the vertical direction.

[0004]

Since this seedling transplanter is constructed as described above, the vertical movement of the rod 27 causes the hole making tool 14 to move to the horizontal axis 1.
It rotates around 6 and when it descends, it projects to the ground and scrapes the soil to make a graft hole. Then, the turning seedling planting rod 7 puts the seedling taken out from the seedling mounting table 6 in the transplant hole and transplants the seedling.

[0005]

As described above, according to the present invention, the hole making tool 14
The seedling planting rod 7 transplants the seedlings into the transplanting holes made in the ground. Then, the hole making tool 14 is attached to the horizontal shaft 16 near the ground by the short arm 15 and pivots around the horizontal shaft 16 to project into the ground to form a transplant hole. Since the front-rear length is short, the back-filling is easy, and since it is rotated by pushing and pulling the lot 27 in the vertical direction, it can be compactly housed in a narrow space, and a multi-row can be easily achieved.

Embodiments of the present invention will be described below. Figure 1
As shown in FIG. 2, a workbench 2 is mounted after a traveling vehicle body 1 (FIG. 2) such as a tractor, and thereafter a seedling planting device 3 is attached by a link 4 so as to move up and down. Has become.

The seedling planting device 3 includes a gear box 5, a seedling mounting table 6 that moves left and right on the gear box 5, and a tip of the seedling mounting table 6 that swivels up and down when viewed from the side in an elongated oval orbit A. A seedling planting rod 7 is provided for taking out one seedling of the seedling that is protruding later. Link 4
The rear end mounting frame 8 and the gear box 5 are connected. The link 4 is provided in the hydraulic cylinder 9 so that the mounting frame 8 at the rear end moves up and down. The workbench 2 is provided with wheels 10 that roll in the valleys of the ridges formed on the ground, and below the gear box 5, a leveling plate 11 that slides on the top B of the ridges is attached. Therefore, when the height of the top B changes with respect to the valley of the ridge, the tip of the leveling plate 11 moves up and down, but the valve 12 is switched by the up and down movement of the leveling plate 11 in the center to cause the hydraulic cylinder 9 to move. By supplying or discharging oil and moving the mounting frame 8 up and down, even if the height of the ridge is changed, the seedling planting rod 7 can be maintained at a constant height with respect to the top B thereof. There is.

A transmission shaft 13 is provided between the gear box 5 and the traveling vehicle body 1, so that the seedling mounting table 6 reciprocates left and right by the power of the traveling vehicle body 1 and the seedling planting rod 7 makes the above-mentioned turning. Has become. As shown in FIG. 3, a wedge-shaped punch 14 having a wedge-shaped front surface is attached to a horizontal shaft 16 near the top B by a short arm 15. A cam 18 is fixed to a shaft 17 that is rotating by the power of the transmission shaft 13, and the lower shaft 1
A roller 21 at the tip of a lever 20 that rotates around 9 is pulled by a spring 22 and is in contact with the cam 18. A rotating body 23 having two arms 23a and 23b is provided on the shaft 24 after the shaft 17, and the shaft 25 of the roller 21 and the arm 23a are provided.
Are connected by a link 26, and the lower end of a rod 27 extending downward from the arm 23b is connected to a lever 28 integral with the arm 15.

When the cam 18 rotates counterclockwise,
The lever 20 rotates clockwise, and the link 26 rotates the rotating body 2.
3 in the counterclockwise direction, the rod 27 descends and the lever 28
Rotates the punching tool 14 in the clockwise direction so that the punching tool 14 rushes into the top B of the ridge to form a graft hole. When the rotation of the cam 18 advances and the roller 21 comes to the surface close to the shaft 17, the spring 22 pulls back the lever 20, the rod 27 moves up, and the hole making tool 14 escapes from the top B. The seedling planting rod 7 puts the seedlings into the thus formed transplanting holes.

As shown in FIG. 2, five seedling planting rods 7 are arranged side by side to form a five-row planting planting device 3. A tip of a U-shaped mounting frame 29 surrounding the seedling planting rod 7 is rotatably mounted on the gear box 7. The rear ends of the five brackets 30 arranged behind each of the seedling planting rods 7 are attached to the mounting frame 29.
It is fixed to. A pair of compression wheels 31 having a truncated cone shape
However, the pressure reducing device is obliquely attached to the bracket 30 such that the small diameter side thereof faces inward and the lower ends thereof approach each other. As shown in FIG. 1, the mounting frame 29 is pushed down by the spring 32, each compression ring 31 acts on the top B of the ridge with a constant pressure, and each pair of compression rings 31 is inserted into the transplant hole. It advances through both sides of the seedling and backfills the transplant hole.
