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, in a rush seedling transplanter that transplants a plurality of seedlings on the left and right, a plurality of grounding devices that support a seedling planting device on a mud surface in a field are provided between the left and right transplanting streaks. Although floats are provided, the interval between planting lines of rush seedlings is set much narrower than that between rice planting lines, so the following inconvenience may occur. In other words, if the grounding float is set wide to increase the grounding area of the grounding float, mud pushing from the side edge of the grounding float that enters between the strips of the rush seedlings and the float edge easily hits the seedlings and the rush seedlings may fall down Will be higher. Conversely, if each of the grounding floats is configured to be narrow so as to suppress the fall of the transplanted seedling, it is not preferable because the grounding area cannot be increased and a float passing deep into the mud surface is formed. Therefore, conventionally, the float portions disposed between the strips are connected to each other at a front portion thereof to be integrally formed, and a large area extending over the right and left sides of the machine body can be secured by the front portion of the integrally connected grounding float.

[0003]

However, heretofore, conventionally, an integrated grounding float has been used so as to simply slide on a mud surface of a field. For this reason,
Even if the step formed at the boundary between the passage trace of the grounding float and the place not passing through is relatively small,
On the mud surface of the field, on the mud surface of the front part of the grounded float, the muddy soil was brought to the trace of passage on the left and right sides corresponding to the front of the grounded float, as a slide mark of the rise of mud caused by the sinking of the grounding float,
In the field scene near the step, streak-like swelling occurs, and the appearance of the field scene is poor, and the drainage of the field is deteriorated, and weeds may grow on the swelling portion exposed from the flooded surface. there were.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and is directed to a float structure of a rush seedling transplanter capable of suppressing the occurrence of mud swelling caused by sinking of a grounding float as a slide mark in a field scene. For the purpose of providing.

[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 its front end, and a fin-shaped elastic grounding plate is moved upward by a predetermined amount or more at each of the left and right ends of the front end of the grounding float. It is characterized in that it is cantilevered so as to protrude laterally outward from both left and right ends of the grounding float in a state where it is regulated. The operation and effect of this characteristic configuration are as follows.

[0006]

[Function] In other words, the narrow floats are placed in the strip after planting so that the ground floats do not come into contact with the rush seedlings, and each float is used to gain the ground contact area in front of each narrow float. The elastic grounding plate, which is cantilevered at the left and right ends of the front end of the wide-area float that connects the parts integrally, suppresses the rise of the mud formed by the sinking of the float. The streak-like swelling generated in the field is leveled by the part. Further, since the elastic leveling plate is provided in a state in which the upward movement of a predetermined amount or more is regulated, even when relatively hard mud is partially projected in the field,
The hard part is pushed into the mud by the elastic leveling board and the ground float itself that are restricted from moving upward,
The field scene can be leveled.

[0007]

As described above, since the sliding trace of the rising of the mud caused by the sinking of the ground float is leveled by the elastic leveling plate, it is possible to suppress the occurrence of troubles such as deterioration of the appearance of the field due to the step, and the like. Since the seedlings were transplanted to the leveled field, it was possible to transplant well.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 shows a rush seedling transplanter. This rush seedling transplanter is configured such that a seedling planting device 3 is connected to a rear portion of a traveling machine body 1 via a link mechanism 2 driven up and down by a hydraulic cylinder 2C so as to be able to move up and down. As shown in FIG. 2, the seedling planting device 3 is a seedling platform 5 that reciprocates left and right at a constant pitch with respect to a planting transmission case 4 also serving as a frame. Each of the mechanisms 6 is attached.

[0009] The block-shaped rush seedlings grown from the parent plant and with the old stock removed are placed and supported on the seedling rest 5 in the standing position for each strip divided by the partition wall 7 from the seedling resting surface. At the stroke end of the horizontal feeding of the seedling placing stand 5 by the projecting endless belt type vertical feeding device 8 arranged in a protruding state, the seedling placing base 5 is configured to be vertically fed by an amount equivalent to one planting, and the seedling is placed.

As shown in FIG. 2, seedlings are cut out one plant at a time by a crank swinging mechanism 11 while drawing a substantially elliptical orbit, and planted in a field.

As shown in FIG. 2, each seedling planting mechanism 6 connected to the planting transmission case 4 so as to extend rearward.
A ground float 12 for supporting the seedling planting device 3 on the mud surface of the field is pivotally mounted on a lower portion of the case portion 6A so as to be able to swing up and down around a support shaft P which is a left-right facing axis. To elaborate,
The grounding float 12 has three float rear portions 13 # arranged side by side in a state of being disposed between the strips of the seedling planting mechanism 6 arranged side by side, and these float rear portions 13 # are integrally connected at a front end portion. A float front part 14 is provided so as to perform the above, and the three float rear parts 13 # are pivotally connected to each other.
