Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to the structure of a frame for attaching a sowing device to a walk-behind rice transplanter after removing the planting device.

(b) Prior Art A flooded direct seeding machine in which a hopper is arranged on the top of a seedling stand of a rice transplanter has been known.
For example, there is a technique described in Japanese Unexamined Patent Publication No. 59-213311.

(c) Problems that the invention aims to solve In the conventional technology described above, the rice transplanter is used as is, so the transplanting devices such as the seedling stand and planting arm remain as they are, and the direct flooding device cannot be attached or removed. The problem was that it was difficult to do so.

The present invention has a configuration in which the seedling stand and the planting claw are all removed and the seeding device is attached to the part.
It is designed to be easily attached and detached.

In addition, when performing direct sowing by flooding, a seeding device, floats, etc. must be attached, but because they are not integrated, assembly is difficult and the work is extremely troublesome. This point is also improved.

(d) Means for solving the problem The present invention is constructed as follows in order to solve the above problems.

In a configuration in which the seedling platform 5 and planting claws of the walk-behind rice transplanter are removed, the mounting frame 2 is attached parallel to the remaining seedling platform rail 18, and the flooding direct sowing device is attached to the mounting frame 2, the mounting frame 2, protrude the side float mounting frame 2b, seeding device mounting frame 2c, and central support frame 2e, and attach the side floats 4, 4 to the side float mounting frame 2b.
The seeding device 1 is attached to the seeding device mounting frame 2c, and the central support frame 2e is fixed to the planting transmission case 9.

(e) Embodiments and operations The purpose of the present invention is as described above, and the operation thereof will be explained together with the structure of the present invention based on the structure of the embodiment shown in the attached drawings.

Figure 1 is a rear view of the mounting frame, Figure 2 is a side view, Figure 3 is a side view of the entire submerged direct seeder, Figure 4 is a rear view, and Figure 5 is a rear view of the marker attached to the mounting frame. , FIG. 6 is a side view, and FIG. 7 is a perspective view of the mounting frame.

To explain from the overall configuration in Figures 3 and 4,
This embodiment is based on a walk-behind rice transplanter for two-row planting.

From the drawing, remove the seeding device 1, mounting frame 2, seeding floats 3, 4, 4, drive device, etc.
If the seedling stand 5, planting claws, etc. are attached, it becomes a rice transplanter for original two-row planting.

The configuration of this walk-behind rice transplanter is that an engine 6 is disposed at the front, power is changed in speed by a transmission case 7, and is transmitted to a planting transmission case 9 via a transmission case 8. A feeding device is driven by a drive shaft 10 of the planting transmission case 9 via a planting claw or a drive arm 11. A base of a handle 17 is fixed to the rear end of the planting transmission case 9, a seedling stand frame 16 is fixed to the inclined part of the handle 17,
Float height adjustment lever 27 at the base of the handle 17
is provided.

Further, lug wheels 13, 13 are driven from the transmission case 7 via swing cases 12, 12, and the swing case 12 is driven by a hydraulic cylinder 14.
The rice transplanter rotates due to the expansion and contraction of the tiller, and the unevenness of the tiller keeps the rice transplanter almost horizontal to avoid meandering and planting mistakes. 15 is a main float, 3 is a center float for seeding, and 4 is a side float for seeding.

The mounting frame 2 of the present invention is fixedly installed at the upper center and lower end of the planting drive case 9, and is attached to the seeding device 1.
and side floats 4,4 are installed. That is,
The mounting frame 2 is, as shown in Figs. 1 and 2,
A side float mounting frame 2b, a seeding device mounting frame 2c, a lower support frame 2d, and a center support frame 2e are integrally fixed symmetrically around the main frame 2a from the outside, and protrude forward from the center. The support frame 2e is fixed to the planting drive case 9, and the lower support frames 2d protruding forward and downward are attached to the lower end of the planting drive case 9, that is, to the driven arm attachment part when the planting claw is attached. The main frame 2a is fixedly installed so as to be parallel to a seedling stand rail 18 horizontally installed on a seedling stand frame 16 fixed to a handle 17.

Then, attach the main frame 2a to the seedling stand rail 18.
The main frame 2a protects the seedling stand rail 18 by making it longer.

The seeding device 1 is installed at the tip of the seeding device mounting frames 2c, 2c that protrude upward from the main frame 2a.
The lower surface of the is fixed. Side float mounting frames 2b, 2 are located below and behind the main frame 2a.
b protrudes, and its tip is fixed to a frame 19 fixed to the upper surface of the side float 4.

Also, markers 2 are placed on both sides of the main frame 2a.
A mounting portion 2f of 0 is provided, and as shown in FIGS. 5 and 6, one end of the marker 20 is pivotally supported. A bracket 21 is fixed to the upper part of the seeding device mounting frame 2c, and a lever 22 is pivotally connected via an arm 23 to rotate the marker 20.

Further, the end of the lever 22 and the base end of the marker 20 are connected by a link 24, and when the lever 22 is rotated laterally, the marker 20 is rotated and set. 25 is a fulcrum crossing spring.

(F) Effects of the invention By configuring the invention as described above, the following effects can be obtained from the invention.

First, by simply removing the central support frame 2e, side float mounting frame 2b, and seeding device mounting frame 2c provided on the mounting frame 2, the seeding device 1, side floats 4, 4, etc. can be removed. When changing to a rice transplanter, it is now possible to easily change to a walk-behind rice transplanter by attaching the seedling platform 5 to the seedling platform frame and the planting claws to the planting transmission case 9. .

Second, since all the flooded direct sowing devices can be attached to the mounting frame 2, the flooded direct sowing device can be prepared in an assembled state, so the walk-behind rice transplanter and the flooded direct sowing device can be assembled. Changes can be made easily.
