Description

[Detailed description of the invention] This invention relates to a leveling device for a rice transplanter, in which the leveling blades of side floats and center floats are arranged so as to be shifted back and forth from each other, and the wheels between the two floats are then The blade is characterized in that the end is positioned further forward than any of the flat blades.

According to the proposed method, since the leveling blades are staggered back and forth, turbulent flow of mud or water between the floats is prevented, the flow is improved, mud is prevented from getting on the leveling blades, and Since the wheel is arranged so that its rear end is located in front of each leveling blade, disturbances in the field caused by wheel marks can be leveled with each leveling blade, and both of the above effects work together to ensure smooth and uniform planting. This has the effect of allowing work to be carried out.

The embodiments shown in the drawings will be described below.

The one shown in Figure 1 is a known rice transplanter.
is the engine, 2 is the seedling stand, 3 is the running handle, 4
5 indicates a planting claw, 5 indicates a center float, 6 and 7 indicate side floats, and 8 indicates a wheel.

In the present invention, the side floats 6, 7 and the center float 5 are provided with the flat blades of the side floats 6, 7 and the center float 5 shifted back and forth relative to each other, and the wheels 8 are arranged so that the rear end thereof is located in front of any of the flat blades. This is what was installed.

In the conventional type, as shown in Fig. 2, the leveling blades 9, 9 of the center float 5 and the leveling blades 10, 11 of the side floats 6, 7 are aligned with each other, so that mud flowing between the floats is removed. The channel suddenly narrows and the muddy water is constricted in this area, so it cannot flow smoothly and mud tends to accumulate in this area, causing mud riding.However, by shifting this level area back and forth. This eliminates the restriction of the waterway and allows mud and muddy water to flow smoothly.

In the embodiment shown in FIG. 3, the leveling blades 10 and 11 of the side floats are provided behind the wheel 8 and in front of the leveling blade 9 of the center float 5. In the embodiment shown in the figure, the leveling blades 10 and 11 of the side floats are provided behind the wheels 8 and behind the leveling blades 9 of the center float.

In addition, A, B, and C in the figure indicate planting positions.

In any of the above cases, the rear end of the wheel 8 is located in front of any of the leveling blades 9, 10, 11, and therefore the disturbance of the field surface caused by the wheel marks is absorbed by each of the leveling blades 9, 10, 11. 11, it is now possible to level the ground. Positioning the leveling blades 9, 10, and 11 behind the rear end of the wheels 8 is particularly effective in leveling the mud that has been scooped up by the wheels 8.

It goes without saying that the protruding length of each leveling blade can be set as appropriate.
