Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rice transplanter, in which the left and right propulsion wheels are moved downward by an independent BKI by a hydraulic system, and the vertical movement is controlled by side leveling floats provided outside the propulsion wheels. ”Regarding the H1 transplanter, which is equipped with a six-row seedling transplanter on a propulsion machine that performs double-down motion.

Conventionally, among the soil leveling floats of this type of rice transplanter, the side floats located on the outside have to move up and down accurately due to fluctuations in the ground pressure on the soil surface, otherwise the vertical movement of the propulsion wheels cannot be controlled accurately. Even though it was small, it was constructed so that the front part was widened on both the left and right sides, giving it a scoop-like shape when viewed from above.

However, in such a configuration, the inner edge approaches the running wheels, and the mud floats ride on the side leveling floats to be lifted up by the running wheels, and even in trenches where the running wheels do not ride, the inner edge approaches the side leveling floats. There was a drawback that the mud was pushed in and increased the vertical resistance of the side leveling floats, and the vertical movement could not be performed accurately and the traveling wheels could not be accurately controlled.

This invention aims to eliminate the above-mentioned drawbacks and has taken the following technical measures.

That is, in this invention, a pair of propulsion wheels (6a) and (6b) are attached to the chain case (7a) on both left and right sides of the fuselage (1).
, through (7b), the machine (

Switching of each hydraulic cylinder device, 4 (lla), (
(25a'), (25b)
The side floats (25a) and (25a) are interlocked to move the propulsion heavy wheels downward when the side floats move up from a predetermined appropriate range, and to move the propulsion wheels upward when they move downwards.
25b), when viewed in plan, the rear side is the two outer seedling planting tools (19a), (19b), (19e),
(19f) Located in the cabinet, the outermost seedling planting tool r11 bulges out to the side at least to the side of the outer part of the nIJ side to an extent corresponding to approximately the spacing of the seedling planting tool (19a), ( +9f)
The outer soil leveling part (a) prepares the ground for planting seedlings.

The configuration of a rice transplanter is as follows: (a), and an inner soil leveling section (b) and (b) that bulges out small and locally inward to level the soil at the second seedling planting position from the outside. By doing so, the front ground contact area of the side soil leveling floats is not affected by muddy water crushing the already planted rows of seedlings during seedling planting work, or by the propulsion wheels holding onto the muddy water. It has the effect of making it possible to widen the area, accurately controlling the vertical movement of the propulsion wheels independently, preventing the aircraft from tilting to the left or right, and keeping the planting depth of each seedling planting tool approximately constant. play.

In the upper configuration, when the seedlings are placed and stored in the ladle tank and each part is driven by the engine (4), the running wheels (6a)
, (6b) is rotated in contact with the tiller surface, and the machine body (1
). And each float (a), (25
a), (25b) floats onto the water [111 surface] and slides down to the ground.

1, each seedling planting tool (+9a) ~ (190 moves up and down, and separates one seedling from the seedling tank O → which moves back and forth from side to side, and each float (a), (25a), (2
Plant on topsoil leveled in step 5b).

In this way, the convex planting (=I) work is performed, but during this work, the tiller becomes shallow or deep, and the machine (1) moves up and down relative to the topsoil surface, and If the depth of the tiller is different and the machine body (1) tilts to the left or right, the side floats (25") and (25")
b) The ground pressure fluctuates and is pushed upward or conversely moved downward.

At this time, the hydraulic switching valves (lla) and (llb) are switched via the wires (28a) and (28b), and the left and right running wheels (6a) and (5b) are connected to the hydraulic cylinder devices (12a) and (12b). ) automatically controls the vertical movement, and the left and right side flows) (25a), (2
5b) The ground pressure is maintained within a proper range.

Therefore, the aircraft (1) is not propelled in a state where it is tilted to the left or right. Moreover, the outer ends of (25a) and (25b) are planted in a specified manner (even if the seedlings are planted at an interval of 1, there is a flow of 1 part) for the already planted rows of seedlings that have been rotated and planted in the forward process. There is no possibility that one row of seedlings will be buried in muddy water by getting too close to the adjacent row of seedlings. Since (b) and (b) are only provided,
The inner part other than this part is the paddy wheel (6a), (
6b) and this paddy wheel (6a),
(6b) may accumulate on the inner side of the side floats (25a), (25b), or the mud raised by the paddy wheels (6a), (6b) may accumulate on the side floats (25a), (25b). 25a), (25b) are in contact with each other, thus the side float (25a).

(25b) can be moved up and down accurately in response to changes in the depth of the tiller, and the propulsion wheels (6a) and (6b) can be precisely controlled up and down.

In addition, the outer ground leveling parts (A) and (A) on the outer end side of the side flow (25a) and (25b) are extended to the rear side) and the outermost side as shown in Fig. 4. Seedling planting tool (19a
