【発明の属する技術分野】
本発明は例えば苗載台及び植付爪を備えて連続的に苗植作業を行う田植機にあって、苗載台など植付部の左右全幅を縮小させるようにした田植機の植付装置に関する。
【0002】
【発明が解決しようとする課題】
例えば10条など多条用田植機にあって、苗載台とともに植付ケース及びフロートなど植付部の左右外側の2条分など複数条分を略90度上方に回動させ機体内側に折畳みする手段があるが、この場合折畳んだ左右外側のフロート間巾が最大巾となり、植付部の左右全幅が余り縮小されず、略6条巾とするためにはフロートを取外す必要がある。また折畳みされた植付ケースや植付ケースの伝動パイプと、本体固定側の苗載台の左右端部とが干渉するため、干渉を回避させるためには全幅が広くなる不都合がある。
【0003】
【課題を解決するための手段】
したがって本発明は、苗載台左右両端の複数条の分割苗載台を、中央固定側の苗載台本体上方に折畳む田植機の植付装置において、植付爪を駆動する植付ケースの左右両端の複数条を分割し、該分割側植付ケース後端のフレームと中央固定側の植付ケース後端のフレームとを、これらケース間略中央位置で回動支点軸を介し回動自在に連結させて、苗載台とともに植付ケースの左右巾も縮小させて、植付部の全幅を規定巾内に良好に縮小させるものである。
【0004】
また、回動支点軸を前高後低状の略45度に傾斜させることによって、分割側の植付ケースの折畳み時にあっては、中央固定側の植付ケースより後方の上方位置に干渉させることなくコンパクトに折畳んで、植付部全幅の良好な縮小を可能とさせるものである。
【0005】
さらに、植付部の左右外側を保護するサイドバンパーを、植付ケースの中央固定側ケースに連結支持させることによって、サイドバンパーの干渉回避など考慮する必要のない植付ケース単独の容易な折畳みを行うとともに、サイドバンパーが畦など障害物に当接した場合にも植付ケースの折畳み部の精度に悪影響を与えることのない良好な折畳みを可能とさせるものである。
【0006】
またさらに、植付ケース後端にブラケットを介しフレームを連結させると共に、分割植付ケースの折畳み時に分割側のフレームを保持するフレーム係合溝を前記ブラケットに設けることによって、分割側植付ケース折畳み時の位置決め装置など別途設けることなく、フレーム連結用のブラケットを有効利用して分割側植付ケースの適正折畳み位置での保持を図るものである。
【0007】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a rice transplanter for performing a seedling operation continuously with, for example, a seedling mounting table and a planting claw. About.
[0002]
[Problems to be solved by the invention]
For example, in a multi-row rice transplanter such as a 10-row, a plurality of rows, such as 2 rows on the left and right outer sides of a planting section such as a planting case and a float, are rotated upward by approximately 90 degrees together with a seedling mounting table and folded inside the machine body. In this case, the width between the folded left and right outer floats is the maximum width, and the entire left and right width of the planted portion is not reduced so much. In addition, since the folded planting case or the transmission pipe of the planting case interferes with the left and right ends of the seedling table on the fixed side of the main body, there is a disadvantage that the entire width is increased to avoid the interference.
[0003]
[Means for Solving the Problems]
Therefore, the present invention provides a planting device for a rice transplanter that folds a plurality of divided seedling platforms at the left and right ends on the left and right ends of the seedling platform body above the center fixed side of the planting case. The frame at the rear end of the split-side planting case and the frame at the rear end of the planting case on the center fixed side are rotatable at a substantially central position between these cases via a pivot shaft. To reduce the left and right width of the planting case together with the seedling mounting table, so that the entire width of the planting portion is favorably reduced to a specified width.
[0004]
In addition, by tilting the pivot shaft about 45 degrees in the front-to-back and rear-to-back directions, when the planting case on the split side is folded, it interferes with an upper position behind the planting case on the center fixed side. This allows the planting section to be folded compactly without any problems, and enables a favorable reduction in the entire width of the planting portion.
[0005]
Furthermore, by connecting and supporting the side bumper that protects the left and right outer sides of the planting part to the center fixed side case of the planting case, it is possible to easily fold the planting case alone that does not need to be considered such as avoiding interference with the side bumper. In addition, even when the side bumper abuts against an obstacle such as a ridge, it is possible to perform good folding without adversely affecting the accuracy of the folded portion of the planting case.
[0006]
Furthermore, the frame is connected to the rear end of the planting case via a bracket, and a frame engaging groove for holding the frame on the split side when the split planting case is folded is provided in the bracket, so that the split side planting case can be folded. Without separately providing a positioning device at the time, a bracket for frame connection is effectively used to hold the split-side planting case at an appropriate folding position.

【The invention's effect】
As is clear from the above embodiments, the present invention provides a rice transplanter that folds a plurality of divided seedling mounting stands (16b) on both left and right ends above a seedling mounting body (16a) on the center fixed side. In the planting device of (1), a plurality of strips at both left and right ends of the planting case (20) for driving the planting claws (17) are divided and fixed to the frame (43) at the rear end of the divided side planting case (20b). The frame (42) at the rear end of the side planting case (20a) is rotatably connected via a pivot shaft (44) at a substantially central position between the cases (20a) and (20b). Therefore, the lateral width of the planting case (20) can be reduced together with the seedling mounting table (16), so that the entire width of the planting portion (15) can be favorably reduced to a specified width.
[0019]
In addition, since the pivot shaft (44) is inclined at an angle of approximately 45 degrees in a front-to-back and rear-to-back configuration, the planting case (20b) on the split side is folded when the planting case on the center is fixed. (20a) The planting portion (15) can be satisfactorily reduced in its entire width without interfering with an upper position behind it.
[0020]
Further, the side bumper (78) for protecting the left and right outer sides of the planting portion (15) is connected and supported to the center fixed side case (20a) of the planting case (20). The planting case (20b) that does not need to be considered such as interference avoidance can be easily folded alone, and the planting case (20b) can be folded even when the side bumper (78) comes into contact with an obstacle such as a ridge. It is possible to perform good folding without adversely affecting the accuracy of the folded portion.
[0021]
Furthermore, the frames (42) and (43) are connected to the rear end of the planting case (20) via brackets (41a) and (41b), and the frame (43) on the dividing side is folded when the dividing side planting case (20b) is folded. ) Is provided in the bracket (41a), so that there is no need to separately provide a positioning device for folding the split-side planting case (20b) or the like, so that a bracket for frame connection (49) is provided. 41a) can be effectively used to hold the split-side planting case (20b) at the proper folding position.
