DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a float structure of a rush seedling transplanter provided with a grounding float for supporting a seedling planting device.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, a ground contact float in a rush seedling transplanter is arranged such that a rear portion 21 of a float disposed between strips is spaced from a transplanted seedling A so as not to contact the transplanted seedling A. The left and right width was small.

[0003]

However, in the above-mentioned conventional structure of the grounding float, since the left and right widths of the float rear portion 21 are small, a large ground contact area cannot be obtained, so that the sinking amount becomes relatively large. Therefore, the mud was easily pushed outward from both left and right edges due to the sinking. Then, the outflow of the mud from the float rear portion 21 to the left and right sides caused a great risk that the transplanted seedlings would be pushed and tilted or fell down.

The present invention has been made in view of the above circumstances, and has a float structure of a rush plant transplanter capable of suppressing the outflow of mud from the left and right edges of a ground float provided between strips. The purpose is to provide.

[0005]

In order to achieve the above object, the float structure of the rush seedling transplanter according to the present invention is arranged such that the grounding float is disposed between the strips of the seedling planting mechanism arranged side by side. The rear part of each float to be connected is integrally connected at the front end thereof, and the lower surface part of each float rear part located on both the left and right sides of the seedling transplant point in a range extending before and after the seedling transplant point in the field is flat. And a float body portion is bulged upward in the middle of the lower surface portion in the left-right direction so as to provide a recessed space into which mud escapes inwardly of both left and right edges of the lower surface portion. This is a characteristic configuration. The operation and effect of this characteristic configuration are as follows.

[0006]

The float body having a bulging structure that gives buoyancy to the ground float at the rear of each float located on both the left and right sides of the seedling transplanting point in the field is a flat plate. Since it is provided above the middle part of the lower surface part formed in the left and right direction, it can be formed in a wide thing relatively close to the left and right transplant shoots with respect to the streak width, so that a large contact area can be secured, The amount of submersion of the grounding float can be reduced, and the mud can escape into the recessed space inside the upper left and right edges of the lower surface. Mud can escape to weaken the flow to the saw.

[0007]

Therefore, according to the present invention, since the amount of sinking of the grounding float can be reduced and the mud transplanted seedlings can escape the mud so as to reduce the flow to the side, the transplanted seedlings can be laid down or tilted. It is possible to suppress the occurrence of mud outflow due to sinking in the rear part of the float, and to maintain the transplanted seedlings in a good planting posture. Furthermore, even if the left and right edges of the lower surface in the rear part of the float are too close to the transplant, the left and right edges of the lower surface are in contact with the transplant in a state located in the mud, There is also an advantage that the transplanted seedlings are less likely to fall down than those that contact the transplanted seedlings at the top.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 shows a rush seedling transplanter. The rush seedling transplanter is configured by connecting a seedling planting device 2 to a rear portion of a traveling machine body (not shown) via a link mechanism (not shown) so as to be able to move up and down freely. This seedling planting device 2 is configured by attaching a seedling mounting table 4 that reciprocates right and left at a constant pitch to a planting transmission case 3 also serving as a frame, and a six-row seedling planting mechanism 5 in a fixed position. doing.

[0009] The block-shaped rush seedlings grown from the parent plant and from which the old stock part has been deleted are placed and supported on the seedling rest 4 in the standing position for each of the strips separated by the partition wall 6 from the seedling resting surface. At the end of the horizontal feed stroke of the seedling rest 4 by the endless belt type vertical feed device 7 with protrusions arranged in a protruding state, the seedling rest 4 is vertically fed by an equivalent amount per planting, and the seedling is placed. Seedling outlet 8 at lower end of table 4
The seedlings are cut out from the seedlings by a planting claw 9 in the seedling planting mechanism 5 and planted in a field. The implant 9 is shown in FIG.
As shown in (1), seedlings are cut out one by one and planted in a field by the crank swinging mechanism 10 while the tip of the seedling follows an almost elliptical locus.

Then, as shown in FIG. 2, each seedling planting mechanism 5 connected to the planting transmission case 3 so as to extend rearward.
In the lower part of the case portion 5A, a ground float 11 for supporting the seedling planting device 2 on the mud surface of the field is mounted on a fulcrum P which is
It is pivotable around it so that it can swing up and down. More specifically, the grounding float 11 has three float rear portions 12 # arranged side by side between the strips of the seedling planting mechanism 5 arranged side by side, and the float rear portions 12 # are connected to the front end portion. Float front part 13 is provided so as to be integrally connected with each other, and the above-mentioned pivotal connection is made at each of three float rear parts 12 #.

As shown in FIGS. 1 to 3, the grounding float 11 has a lower surface portion 14 formed of a series of synthetic resin plates in a flat plate shape and a synthetic resin resin material provided on the upper surface of the plate material forming the lower surface portion 14. Is formed by bulging and molding. And the float main body part 15 is
As shown in FIG. 3, the upper part of the lower surface 14 between the outer edge 14a and the rising portion of the float main body 15 is swelled and formed so as to rise from an inner portion of the outer edge 14a. , A concave space S is formed. Accordingly, in a range extending before and after the seedling transplanting point in the field, each of the float rear portions 12 # located on both the left and right sides of the seedling transplanting point has a lower surface 1 as viewed in the front-rear direction.
In the middle in the left-right direction of FIG. 4, the float main body 15 is bulged upward in a state where the cross-sectional shape is substantially rectangular, and as shown in FIG. The mud extruded outward from the lower surface portion 14 can escape into the recessed space S above the outer edge 14a of the lower surface portion 14. Therefore, when arranging the flat lower surface portion 14 between the transplanting strips, the left-right width of the lower surface portion 14 is set to be larger than the left-right width of the float main body portion 15. Since the edge 14a can be configured to be wide so as to be close to the transplanted seedlings of the both ends, the contact area becomes large, and while the sink of the contact float 11 is suppressed, the mud extruded by the sink is transplanted as much as possible. The seedlings escape to the recessed space S so as not to flow on the alligator.

In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the structure shown in the attached drawings.
