Description

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

(Prior art) 〓 between center float and side float
A rice transplanter with equal width between
It is known from Publication No. 88713.

(Problem to be solved by the invention) In the conventional rice transplanter as described above, the passage of water flowing between the center float and the side floats becomes narrower, the flow rate of the water becomes faster, and the flow rate of the water becomes faster. The impact of water is enormous. Furthermore, the water displaced by the side floats flows to the outside of the side floats and does not flow between the side floats and the center float, which has an adverse effect on adjacent seedlings. Therefore, the object of the present invention is to eliminate this conventional drawback and provide a float device for a rice transplanter that does not have a negative effect on planted seedlings.

(Means for Solving the Problem) In order to achieve the above objectives, the present invention provides the following float device for a rice transplanter.

That is, in a rice transplanter having a plurality of floats, the side portion of the upper surface of the center float is formed thinner than other portions, and the starting end of the thin portion is near the tip of the side float or in front of the tip. This is a float device configured as follows.

(Effect of the invention) In a rice transplanter having a plurality of floats, the side portion of the upper surface of the center float is formed to be thinner than other portions, and the starting end of the thin portion is near the tip of the side float or closer to the tip of the side float. The structure is such that the water flowing between the center float and the side floats becomes wider, slowing down the flow rate of the water, and thus reducing the influence of water on the planted seedlings.

In addition, since the side float tip is thinned from the front, the water displaced by the side float can easily flow between the center float and the side float, and this also allows water to flow outward from the side float. This reduces the negative impact on neighboring seedlings.

In addition, by simply forming the upper side portions of the center float thinner than the other portions, the water flow path becomes wider and a rim is formed on the sides of the center float, creating a strong center. A float is provided, and the ground contact area of the center float does not change, allowing for stable running.

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

FIG. 1 shows an example of a rice transplanter. 1 indicates a running vehicle body, and the running vehicle body has a front wheel 3 and a rear wheel 5 at the front and rear of a body frame 2, and the rear wheel 5 is connected via a chain case 4. installed.

A driver's seat 6 and a handle 7 are provided on the upper surface of the vehicle body frame 2, and each wheel 3, 5 is driven by an engine on the rear upper surface of the vehicle body frame 2 to drive the vehicle.

Reference numeral 9 denotes a parallel link mechanism 1 at the rear of the traveling vehicle body 1.
0 shows a seedling planting device that is movably mounted vertically,
The seedling planting device 9 includes a transmission case 11 and a planting case 1.
3, 13, 13, floats 14, 15, 14 arranged on the lower surface of each planting case and the upper end of the vehicle body 1
It consists of a seedling stand 16 that is inclined so as to approach the
At the rear of each planting case is a vertically swinging seedling planting mechanism 1.
A single-acting hydraulic cylinder 18 is provided between the traveling vehicle body 1 and the parallel link mechanism 10 for raising and lowering the seedling planting device 9 with respect to the field. The other 19 are auxiliary seedling stands.

The present invention relates to an improvement of the float for a rice transplanter as described above, in which the side portions of the upper surface of the center float 15 are formed into thin walls 15a, 15a, and the beginnings of the thin portions 15a, 15a are located at the side floats. 14, 14 is made thinner from the front than the tip, so the passage A of water flowing between the center float and the side floats becomes wider.
Therefore, it is possible to prevent the flow rate of the running water from slowing down and adversely affecting the planted seedlings.

In addition, since the water displaced by the side floats easily flows between the center floats, the amount of water flowing outward from the center floats is reduced and does not adversely affect adjacent seedlings.
