Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a planting aid for a rice transplanter.

(Prior art) Conventionally, in rice transplanters, the planting part of the float has a special shape to prevent muddy water from flowing into the planting part, thereby reducing seedling collapse and row shifting. .

(Problems to be solved by the invention) According to the above, the float itself must have a special shape, and it is only used to prevent the flow of muddy water to the planting area. It is not a matter of holding down the mud that collects to the sides and planting firmly at the base.

(Means for solving the problem) Therefore, the technical problem of the present invention is to provide a planting aid for a rice transplanter that enables stable planting, and to solve this technical problem. The technical means of this proposal is that the seedlings are located on both sides of the planted seedlings, have a certain length from the front to the rear, and have a shape in side view that changes from a wide shape to the rear. A rice transplanter's planting aid consisting of a long and narrow shape is used as a rice transplanter's planting device.

(Effects of the invention) According to this technical means, it is possible to plant with firm roots by holding down the mud that is gathered to the side with the planting claws of the planting aid, and the shape of the planting in side view is also possible. This allows the mud to escape little by little from the rear, thereby suppressing the generation of mud vortices behind the auxiliary tool, preventing the mud from escaping at the root, and stabilizing the planting soil for proper planting. Can maintain posture.

Furthermore, by making it separate from the float, it can be easily installed using the float or body of an existing rice transplanter.

(Example) The embodiments shown in the drawings will be described below.

The first and second illustrations show a one-wheel, two-row walk-behind rice transplanter, in which an engine 3 is mounted on the tip of the left and right eight-row rice transplanter frame 1 via an engine stand 2, and the rear end is equipped with an engine 3. A platform 4 and an operating handle 5 are provided. A single walking wheel 6 is located between the engine 3 and the seedling stand 4.

The base end of a swing case 7 is swingably connected to a transmission case to which power is transmitted from the engine 3, and the one-wheeled traveling wheel 6 for paddy fields is rotatably supported at the tip of the swing case 7. .

A telescopic load 11 operated by a swing handle 10 supported via a gate-shaped arm 9 connecting the left and right planting claw drive cases 13, 13 is connected to the swing case 7 via a swing lever 12,
This allows the degree of swing of the swing case to be adjusted.

Reference numeral 14 denotes a planting height adjustment section, and its mounting fitting 14a is connected to a stop section near the rear end of the float 15.

The front end of the float 15 can swing about a fulcrum 14a by means of a slit groove 18 of a swing arm 16 and a pin 17 of the machine frame 1 that engages with the slit groove 18 of the swing arm 16.

In addition, 18 is a main clutch lever, and 19 is a planting claw part.

The present invention relates to a planting aid that allows a stable planting posture to be achieved in the rice transplanter as described above.

Reference numeral 20 denotes a planting aid, and the one shown in the figure is attached to the side of the float 15, and its overall shape is a horseshoe shape when viewed from above, and its tip is connected to the float stepped portion 1.
5a is shown attached with bolts and nuts 21.

Reference numeral 22 indicates a seedling to be planted, which is surrounded on both sides by a planting aid when planting the seedling using a planting claw.

As shown in FIG. 8, the side view shape of the planting aid 20 starts from a wide shape and becomes narrower toward the rear. The plan view shape and cross-sectional shape of this planting aid 20 may be any of the following combinations. That is, in the plan view shape shown in FIG. 5, the center portions of the pair of left and right auxiliary plates are enlarged and narrow in the front and back, and in the plan view shape shown in FIG. The auxiliary board is expanding. Moreover, the planar view shape shown in FIG. 7 has a shape that widens out in a tulle shape at the rear end. The cross-sectional shape shown in FIG. 9 is different at the front, center, and rear.

In any case, the planting aid of this proposal is the planting seedling 22
located on both outer sides of the body, and has a certain length from the front to the rear, and its side view shape starts from a wide shape and becomes narrower toward the rear. Therefore, the auxiliary board at the time of planting surrounds the planting position of the seedlings, and has the effect of holding down the muddy soil that gathers to the sides with the planting claws, thus allowing planting with firm roots. can stabilize the soil. However, since the rear end is narrow, the mud is allowed to escape little by little from here, so it is possible to suppress the generation of vortices at the rear end position, prevent the mud from escaping at the base, and create an appropriate flow. It is possible to maintain the planting posture.

If the width in side view is the same in the front and back, a vortex will be generated at the rear end of the auxiliary board, and there is a risk that mud will quickly escape, making it impossible to plant properly.
