Description

[Detailed Description of the Invention] The present invention is a rice transplanter leveling device in which a leveling plate for erasing wheel marks is attached near the front end of a float placed behind the rear wheels so as to protrude outward from the outer edge of the float. It is related to.

The above-mentioned ground leveling device is designed to prevent the leveling plate from floating up from the mud surface due to irregularities in the running ground when the leveling plate is attached to the aircraft body, thereby making the leveling effect uncertain. A leveling plate is attached to the float itself, which follows the mud surface.

However, in the past, the leveling plate was attached to the outer edge of the float so as to extend toward the outside of the float, so it was difficult to push mud with a wide width equal to the width of the float plus the width of the leveling plate. As a result, mud pushing resistance increased, and the amount of mud flowing outward from the outer edge of the leveling plate increased, which could have a negative impact on the planting area.

This invention is designed to prevent the above-mentioned problems from occurring when directly attaching a leveling plate for erasing wheel marks on a float. In the soil leveling device of a rice transplanter, in which the base plate is installed with the base plate protruding outward from the outer edge of the float,
The lateral edge of the ground leveling plate on the float side is located inward of the float from the outer edge of the float, and a space is provided in the front-rear direction between the front mud pushing surface of the float and the leveling plate, It is characterized by the formation of a mud clearance space that penetrates from side to side.

In other words, by partially overlapping the leveling plate and the float in the left-right direction, while ensuring the leveling effect at the boundary between the leveling plate and the float, the width of mud pushing by the leveling plate and the float can be set wide. Moreover, even if the mud pushing width is wide overall, because the phase of the leveling plate and the mud pushing surface at the front end of the float are shifted back and forth, and there is a gap, a part of the mud flow pressed by the leveling plate is pushed by the float. A part of the mud flows outward to the front of the float, and the mudflow at the front of the float flows outwards of the float through the mud clearance space formed between the ground leveling plate and flows out to the back of the leveling plate. .

Therefore, unlike in the past, the mudflow caused by the leveling plate and the mudflow caused by the floats do not combine and concentrate in one place, but instead flow effortlessly and smoothly as they are dispersed back and forth. It was possible to reduce both the drop in resistance and the negative impact on the planting site.

Embodiments of the present invention will be described below based on the drawings.

Fig. 1 shows a riding type rice transplanter, in which a four-row seedling planting device 4 is raised and lowered at the rear of a passenger vehicle body 3 equipped with drive-type steering front wheels 1, 1 and drive-type rear wheels 2, 2. freely connected.

The seedling planting device 4 is equipped with a center float 5 for leveling the two rows in the center, and a pair of left and right side floats 6, 6 for leveling the ground for one row on the outside.
The center float 5 also serves as a ground sensor for controlling the height of the seedling planting device 4 to a constant level with respect to the planting mud surface, and is linked to the raising/lowering control mechanism of the seedling planting device by known means.

The rear wheels 2, 2 are arranged at intervals of two rows so as not to pass through and disturb the planned planting position, and in order to make the tread as large as possible to ensure the stability of the machine body, It is constructed as a wheel with inward lugs that can be moved closer to the planned outside planting position. In deep fields, the second
As shown by the imaginary lines in the figure, the auxiliary wheels 7, 7 can be attached to the outside of the rear wheels 2, 2 in a four-striped manner.

In addition, on the left and right front ends of each side float 6, there are ground leveling plates 9, 9 whose lower ends are rake-shaped via brackets 8.
is installed in a height-adjustable manner, and the rear wheels 2,
Alternatively, it is configured to press and level the earth clods that have been lifted up and raised in the passage grooves of the rear wheels 2 and the auxiliary wheels 7 and the sides thereof.

The ground leveling plate 9 is arranged such that its outer end protrudes further outward than the outer edge of the float 6, and its inner end overlaps the outer edge of the float 6 slightly towards the inner side of the float. , and between the mud-pushing surface S at the front end of the float 6 and the leveling plate 9, a space A for mud removal passing through from side to side is formed.

According to the above configuration, the mudflow generated on both the left and right sides of the left and right leveling plates 9, 9 in each side float 6 is a mudflow flowing rearward from the outer ends of both leveling plates 9, 9.
A mudflow flows backward from between the two leveling plates 9, 9, and the mudflow in the center is a mudflow between the float 6 and the leveling plates 9, 9 along with the mudflow to the left and right generated by the mud pushing surface S at the front end of the float 6. The mud flows backward from the backs of the ground leveling plates 9, 9 through the clearance spaces A, A, and becomes a mud flow dispersed back and forth on the left and right outer sides of the float 6.
