Description

[Detailed description of the invention] This invention relates to a side float structure of a single-wheel multi-row rice transplanter.

Conventionally, single-wheel, multi-row rice transplanters have one wheel in the center and floats symmetrically installed on both sides, but because there is only one wheel, there is poor lateral stability and lateral subsidence can occur. In addition, in soft fields, the floats on the left and right sides of the wheels may sink, making it difficult to drive while planting.Furthermore, since it runs on one wheel, it is difficult to drive straight. The disadvantage was that it was difficult to drive and it was difficult to align the rows with side markers.

In this invention, side floats are further provided on both sides of the float attached to the body frame of the rice transplanter so that they can swing in the forward direction, and the side floats are only one row away from the position of the outermost planting part. By arranging it so that the edge is located on the outside, it prevents the machine from sinking from side to side, keeps the planting depth constant, and allows reliable planting work, as well as keeping the planting rows in line with the adjacent already planted rows. It is an object of the present invention to provide a side float structure for a single-wheel multi-row rice transplanter, which allows row alignment to be performed using the outer edge of the side float as a mark, and which facilitates row alignment.

A detailed description of the embodiment of this invention based on the drawings shows a one-wheel multi-row rice transplanter, in which an engine 2 is attached to the front of the machine frame 1, and an interlocking case 3 is connected to the engine. ing. A pair of left and right hollow side frames 4 and 5 extending rearward from both left and right ends of the interlocking case 3 are configured in a U-shape in plan and are connected to the fuselage frame 1. The front end of a swing case 6 extending rearward between 4 and 5 is rotatably pivoted, and a running wheel 7 located on the center line in the width direction of the fuselage frame 1 is provided at the tip of the swing case 6. It is being

Seedling planting cases 8 and 9 are fixed to the rear ends of both side frames 4 and 5, and the cases 8 and 9 are connected by a gate-shaped connection frame 10. The seedling planting cases 8 and 9 are connected with a handle 11 that extends rearward, and the handle has a front support that is horizontally movable horizontally by a guide rail 12 and a rail mechanism 13. A seedling platform 14 with a low rear height is provided, and a seedling planting mechanism 15 is installed in front of the lower end of the seedling platform.
is connected to the seedling planting cases 8 and 9 and is arranged to be able to freely reciprocate.

On the outer periphery of the seedling planting mechanism 15 and the seedling stand 14, a rectangular bumper 16 is connected to the rear side of the seedling planting cases 8, 9 and the seedling stand 14, and side bumpers 17 are provided on both sides of the bumper. Form and seedling stand 1
It surrounds both sides of the guide rail 12 of No. 4.

A pair of left and right floats 1 are provided on both left and right sides of the wheel 7.
8 and 19 are provided, and the rear end of the float is attached to the base of the handle 11 via a planting depth adjustment mechanism 20, and the front end is attached to the hollow side frames 4 and 5 independently via links 21. It is mounted so that it can move up and down. Furthermore, in the outer direction of the pair of left and right floats, the outer edges 22', 23' of the side floats 22, 23 are positioned one row outward from the position of the outermost planting part of the single-wheel multi-row rice transplanter A. The side floats 22 and 23 are arranged in the bumper 16 as follows, and the floats 22 and 23 are attached to the bumper 16 so as to be swingable in the straight direction. That is, the side floats 22,2
3, the rear part of the side float is pivoted 26 via a bracket 25 to a float support rod 24 vertically installed at the rear base end of the side bumper, and a long groove 28 is provided at the front part of the side float via a bracket 27. The lower end of the guide rod 29 is pivoted 30, and the front base end of the side bumper 17 is loosely fitted into the long groove 28 of the guide rod 29. In addition, the float support rod 24
A coil spring 31 is attached to the pivot portion between the lower end and the bracket 25, and the side floats 22, 23
The front part of the machine is biased in a raised position.

In the figure, M indicates the outer row of seedlings that have already been planted.
m indicates a shoot under planting.

The embodiment of this invention is constructed as described above, and when traveling for planting, the single-wheel multi-row rice transplanter A is moved by the floats 18 and 19 using the running wheels 7 arranged in the center of the machine frame. It travels while holding the field horizontally, and cuts and plants seedling blocks from the seedling pine on the seedling platform 14 using the seedling planting mechanism 15. During such planting travel, the side floats 22, 23 is float 18,
It is located on the outer side of 19 and holds the left and right sides of the aircraft above the water surface, preventing the left and right sides from sinking due to left and right rocking due to the single running wheel, and preventing each planted seedling from settling. In order to keep the depth constant on the left and right sides and to run straight ahead during planting, if you run with the outer edges 22' and 23' of the side floats aligned with the outer row M of the already planted seedlings, you can easily move from the control part. The positions of the side floats 22 and 23 can be easily seen and the rows can be easily aligned.

According to this invention, in a single-wheel multi-row rice transplanter, the side floats are arranged on both outside sides, and the edge part is located one row outside the position of the planting part at the outside end. It is easy to align the rows using the mark as a guide, improves straight planting performance, prevents the machine from sinking to the left and right, makes it possible to maintain a constant planting depth, and even in soft fields. It is possible to hold the aircraft in the field by the action of the float and side float.
Furthermore, since the original float and side floats are arranged on both sides of the single central running wheel, the stability of the aircraft body is good and the steering wheel can be easily operated.
