Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a spare seedling storage device for a riding type rice transplanter.

[0002]

2. Description of the Related Art Conventionally, as a preliminary seedling storage device for a riding type rice transplanter, a support arm is rotatably extended laterally around a longitudinal axis and a preliminary seedling stand is provided in a plurality of upper and lower stages. The lower end of the second support column is supported by the free end of the support arm, and when the preliminary seedling is supplied from the ridge side, the preliminary seedling mounting table is extended around the vertical axis to the ridge side and is rotatable. In this configuration, since the lower end of the second column is supported by the free end of the support arm, the height of the support arm is set higher than the height corresponding to the upper surface of the ridge. , The support arm was designed not to hit the ridge during the above-mentioned overhanging rotation.

[0003]

However, according to the above-mentioned conventional structure, since the height of the support arm is set higher than the height corresponding to the upper surface of the ridge, the center of gravity of the preliminary seedling storage device is high. So there was room for improvement in terms of stability.

An object of the present invention is to improve the stability of the preliminary seedling storage device.

[0005]

[Means for Solving the Problems]

[Structure] The characteristic structure of the invention according to claim 1 is that the first support pillar is erected on the traveling machine body so as to be rotatable around its axis, and the support arm is extended laterally from the upper end of the first support pillar. The upper end portion of the second support column having a plurality of preliminary seedling mounts arranged above and below is suspended and supported by the support arm.

According to a second aspect of the invention, in the invention according to the first aspect, the upper end portion of the second support is hung and supported by the support arm so as to be rotatable around the axis of the second support. There is a thing.

According to a third aspect of the present invention, in the first or second aspect of the invention, the upper end of the second support column is detachably provided on the support arm.

According to a fourth aspect of the present invention, in the invention according to any one of the first, second and third aspects,
The second cylinder is constituted by an outer cylinder provided with the preliminary seedling mounting table and an inner cylinder into which the outer cylinder is slidably fitted, and an outer cylinder slidably moving with respect to the inner cylinder. By providing a moving means, the preliminary seedling placing table is configured to be freely switchable between the descending state of receiving the preliminary seedlings and the raising state of the preliminary seedlings.

[Operation] According to the structure of claim 1, when the preliminary seedlings are replenished from the ridge side to the preliminary seedling mounting table, the first support column is rotated around its axis to swing the support arm, and the preliminary seedlings are rotated. The mounting table is extended to the ridge side to supplement the seedlings.

In this case, since the second supporting column provided with the preliminary seedling mounting bases in a plurality of upper and lower stages is suspended and supported by the supporting arm, the lower end of the second supporting column is brought close to the height corresponding to the upper surface of the ridge. Therefore, the center of gravity of the preliminary seedling storage device can be set low.

According to the structure of claim 2, in addition to the same operation as that of the structure of claim 1, the upper end of the second support column is supported by the support arm around the axis of the second support column. Since the second support is rotatably suspended and supported, the second support is rotated around its axis to swing the support arm, thereby changing the direction of the preliminary seedling mounting table to a position where the preliminary seedlings can be easily replenished. be able to.

According to the configuration of claim 3, claim 1 or 2
In addition to the same effect as that of the configuration described above, since the upper end portion of the second support column is detachably provided on the support arm, when performing an intermediate work such as fertilization work,
The weight of the aircraft can be reduced by removing the support column from the support arm.

According to the structure of claim 4, in addition to the same effect as that of the structure of any one of claims 1, 2 and 3, the auxiliary seedling stand can be operated in the lowered state. Since it is configured to be able to switch between the reserve seedling receiving posture and the raised seedling removal posture, for example, when the ridges are lower than the standard one, the reserve seedling mounting table is lowered. It is possible to replenish supplementary seedlings after setting the seedling receiving posture.

[Effect] Therefore, according to the structure of claim 1, since the center of gravity of the preliminary seedling storage device can be lowered, the stability can be improved, and the preliminary seedling mounting in a larger number of stages than the conventional case. It became possible to install a stand.

According to the structure of claim 2, in addition to the same effect as the structure of claim 1, it is possible to change the direction of the preliminary seedling table so that the preliminary seedlings can be easily supplied. Therefore, it was possible to improve the workability of the supplementary seedling supply work.

According to the configuration of claim 3, claim 1 or 2
In addition to the effect similar to that of the configuration described above, when performing an intermediate work such as fertilization work, the self-weight can be lightened, so that the workability of the intermediate work can be improved.

According to the structure of claim 4, in addition to the same effect as the effect of any one of claims 1, 2 or 3, the ridge becomes lower than the standard one. Even if it is, the workability of the work for supplying the spare seedlings could be improved because the spare seedling mounting table can be lowered to facilitate the supply.
