Description

[Detailed description of the invention] This invention is configured so that the planting is propelled by wheel drive, and a float is attached to the aircraft body so that the vertical position can be changed and fixed, and the planting depth can be changed freely. The present invention also relates to a rice transplanter which is provided with a leveling plate for leveling the wheel marks at a position rearward of the wheels.

Conventional ground leveling plates generally flatten the ground by pressing a flat plate into the ground, suppressing and dispersing the mud left by the wheels to both sides, leveling the ground, and leveling the ground. There was an inconvenience that the water flowed from both sides of the leveling board into the planting area, causing the planted seedlings to fall over.

In view of the above points, the present invention prevents mud from flowing into the planting area during land leveling, and eliminates the need for adjusting the planting depth regardless of changes in the planting depth. The purpose is to level the ground and make it accessible.

Next, embodiments of the present invention will be described in detail based on the drawings.

Planting with wheels 1 and 1 mounted on axle requires 1 person on the aircraft and 2 floats...
... is suspended and supported, and for planting, engine E is mounted on the front of one person in the aircraft, and a steering wheel 3 is extended to the rear, and it moves back and forth in the lateral direction behind wheels 1. A seedling mounting table 4 with a front curved slope is provided to feed the seedlings downward, and a seedling planting device 5 is provided at the rear thereof to take out the seedlings from the lower part of the seedling mounting table 4 and plant them on the planting mud surface. This is a walking-type rice transplanter designed to continuously plant seedlings as it travels.

For planting, the float 2 connects its front end to the fuselage IA via a link 6, and connects the intermediate part to a bracket 7 connected to the top surface of the float 2.
The bracket 7 has three mounting holes 8 at predetermined intervals in the vertical direction.
・It is configured so that the installation position can be changed to three levels (upper and lower) and the planting depth can be changed.

Behind each of the wheels 1, 1, and the float 2...
In order to prevent the mud thrown up by the wheels 1 from getting on the sliding guide part 9 of the seedling mounting table 4, a cover 10 is connected to the transmission case 11.
For seedling planting, which is arranged behind the wheels 1, 1 and on both sides of each wheel 1, 1, a bracket 12 is attached to a portion of the cover 10 corresponding to the front position between the claws 5a, 5a. are connected in parallel with each other, and the ground leveling plate 1 is attached to the bracket 12.
3 are pivotally connected to each other so as to be able to swing freely, and are constantly urged toward the pressing ground side via a tension spring 14, and the stopper 1
5 to regulate the lower limit position, thereby leveling the wheel marks and leveling the ground.

The ground leveling action part 16 of the ground leveling plate 13 has a cutout part 17 extending from the lower end side upward at a predetermined interval in the lateral direction.
. . . are formed side by side, and the structure is such that mud washed away as the land is leveled is allowed to pass through the notches 17 .

The cutout portions 17... are each connected to the float 2.
When the installation position of ... is closest to the aircraft side, that is, when it is changed to the maximum depth, its upper end is above the top surface of float 2... Regardless of whether or not the planting depth is changed, the mud that is washed away due to land leveling will be removed from the notch 17.
It is designed to pass through...

The spacing between both ends of the soil leveling action portion 16 of the soil leveling plate 13 and the planting portion 18 of the adjacent seedling planting device 5 is configured to be equal, and is about 50 to 60 spacings to give a numerical example. .

The upper end of the notch 17 is located at the maximum depth of planting, at least above the planting mud surface, and the upper end of the notch 17 is located at the maximum depth for planting. Any material may be used as long as it forms a gap between it and the mud surface through which the washed mud can pass.

As shown in the above embodiments, the characteristic configuration of the rice transplanter according to the present invention is that the rice transplanter according to the present invention has a float attached to the machine body that can be moved up and down and fixed. , a rice transplanter in which a seedling planting device is arranged in such a manner that seedlings are planted at a position behind the wheels, and seedlings are planted by claws at positions on both sides of the track where the wheels pass, behind the wheels; In addition, when planting the seedlings at a position forward of the location, a ground plate for leveling wheel marks is installed on the machine body, and the leveling action part of the leveling plate for leveling wheel marks is provided with the ground plate from the lower end thereof. The mud removal notch is formed above the upper slope of the float's vertical position change range, and this configuration provides the following effects.

For a long time, the notch 17...
... to flow backward within the width of the leveling plate 13, suppressing the mud from being swept away to both sides of the leveling plate 130, and preventing the mud from being swept away for planting. We have been able to reduce problems such as knocking down seedlings as much as possible.

Moreover, to change the planting depth, float 2...
Even if the vertical position is changed, the notch 17 of the land leveling action part 16 is formed to allow the passage of mud washed away by land leveling, so for example, when planting on a headland area, In addition, even if the planting depth is changed during the work, there is no need to change or adjust the mounting position of the leveling plate 13.
We were able to successfully level the wheel marks.

Furthermore, the fact that the ground leveling plate 13 is installed on the aircraft body IA side means that, for example, compared to the case where the leveling plate 13 is installed on the float 2 side, the front part of the float has a convex part on the mud surface. Another advantage is that the ground leveling plate does not act as a resistance to sinking of the rear part of the float and obstruct smooth swinging of the float, which is an inconvenience that causes a deterioration of the swinging function.
