Description

[Detailed Description of the Invention] The present invention relates to a float in a rice transplanter that causes the planting part to slide following the rice field.

Conventionally, rice transplanters are equipped with floats that allow the planting part to glide along the rice field.This float consists of a center float located at the center of the left and right sides of the machine, and a muddy water channel spaced on both sides of the center float. Many of them are constructed with side floats placed at a certain distance, and the side floats support the planting part in a stable position on the rice field, and the side floats are used to support the planting area by the passage of the aircraft's propulsion wheels. This serves to fill in the wheel marks and level them out.

In general, for rice transplanters that plant 5 rows or more, the width of the planting area is wide, so it is possible to position side floats on both sides of the center float behind it to match the width of the machine's propulsion wheels. It is easy to do, and the ground is well leveled with the wheel marks, but since the width of the planting area is narrow for rice transplanters that plant 4 rows or less, it is necessary to arrange the side floats so that they are completely aligned with the rear of the machine's propulsion wheels. It was difficult to level the ground from the wheel marks, which hindered the proper planting of seedlings.

In view of the above-mentioned circumstances, the present invention has been developed by providing a downward protrusion on the outside of the front part of the side float to collect mud inward, and a concave groove on the bottom of the side float to guide the mud inward. In addition, the protrusion is formed in an inclined shape so that the rear end side is at the same height as the bottom surface of the side float, and the structure is configured to spread and level mud on a smooth and wide leveled surface. The downward protrusion of the side float scrapes the soil mass that rises outside the wheel mark caused by the passage of the propulsion wheel inward, embedding the wheel mark.
The raised part of the soil clod is leveled, and the side floats completely level the ground to prevent problems with planting seedlings.At the same time, the downward protrusion of the side floats supports the downward protrusion to prevent the aircraft from rolling. The present invention aims to provide a float for a rice transplanter that can further improve the leveling performance of rice fields and the ease with which seedlings can be planted.

To explain the structure of the present invention with reference to an embodiment shown in the drawing, the drawing shows an example of a four-row rice transplanter, in which 1 is a traveling part, 2 is a planting part, and In the section 2, a center float 3 is disposed at the left and right center of the body, and side floats 4, 4 are disposed on both sides of the float at an interval of muddy water channels 5, 5, and the planting section 2 is equipped with these floats. The center float 3 and side floats 4 allow it to slide following the field. 6 is a seedling stand of the planting section 2, 7 is a planting mechanism, and 8 and 8 are the running section 1.
The side floats 4, 4 are located behind the body propulsion wheels 8, 8.

The side floats 4, 4 have fin-like leveling surfaces 4a, 4a that spread outward at their front parts, respectively, and on the outside of the leveling surfaces 4a, 4a, there are provided surfaces for raking mud inward. Downward protruding parts 4b, 4
b is integrally formed facing rearward and outward. The downward protrusions 4b, 4b are hollow and have a shape whose width narrows downward. The protruding portion 4b is formed in an inclined shape so that its rear end side is at the same height as the bottom surface of the side float 4, and the rear end side of the leveling surface 4a is smooth and wide. Furthermore, grooves 9 are formed in the leveled surface 4a to guide the collected mud toward the inner side, that is, toward the wheel marks of the vehicle propulsion wheels 8.

In the rice transplanter configured as described above, the planting section 2
is towed by the running section 1, and the planting section 2 slides on the rice field by the center float 3 and side floats 4, 4, and moves up and down following the rice field. and,
The planting mechanism 7 plants seedlings. As the traveling section 1 advances, wheel marks are created on the rice field due to the passage of the vehicle propulsion wheels 8, 8, and clods of earth are raised on the outside and inside of the groove of the wheel marks. However, as the side floats 4, 4 of the planting section 2 slide on the rice field, the wheel marks are buried and leveled, which hinders the planting of seedlings by the planting mechanism 7 of the planting section 2. It never happens. That is,
The clods of soil that have piled up on the outside of the wheel marks are scraped inward by the downwardly protruding parts 4b, 4b of the side floats 4, 4, and further guided toward the wheel marks by the grooves 9. , can completely fill in the wheel track grooves. The soil piled up in the groove of the wheel track and around it is dispersed and leveled by the smooth and wide rear end side of the leveled surface 4a. In this way, the side floats 4, 4 are formed with the downwardly protruding parts 4b, 4b on the outside of their front parts, so that the side floats 4, 4,
4 has a wide ground leveling range, and even if the center lines of the body propulsion wheels 8, 8 and the side floats 4, 4 do not necessarily coincide, a sufficient ground leveling effect can be obtained. Therefore, the side floats 4, 4 are 4
Like rice transplanters for row planting and below, the machine propulsion wheels 8,
This is particularly effective when it is difficult to arrange the side floats 4, 4 in alignment with the rear of the floats 8.

In addition, the downwardly protruding parts 4b, 4b formed on the left and right side floats 4, 4 support the planting part 2 in the left and right direction with respect to the rice field, so the planting part 2
It is possible to reduce the horizontal shaking of the plant and improve the ease of planting seedlings.

In short, the present invention provides a center float at the center of the left and right sides of the aircraft body, and side floats are arranged on both sides of the center float, and a downward direction is provided on the outside of the front part of the side float to collect mud inward. A protrusion is provided, and a groove for guiding the mud inward is provided on the bottom surface of the side float, and the protrusion is formed in an inclined shape so that the rear end side is at the same height as the bottom surface of the side float, so that the surface of the side float is smooth. Since the structure is designed to spread and level the mud on a wide leveled surface, the downward protruding parts of the side floats scrape up the clods of soil that rise outside of the wheel marks caused by the passing of the aircraft's propulsion wheels, and then the concave grooves In addition to embedding wheel marks by guiding the soil inward, it is possible to spread and level the raised part of the soil clod on a smooth and wide leveling surface. In addition, the supporting action of the downward protrusion of the side floats reduces the horizontal sway of the aircraft, further improving the leveling performance of the rice field and the ease with which seedlings can be planted. It has a useful practical effect.
