【考案の詳細な説明】 「産業上の利用分野」 本考案は例えば6条或いは8条など多条大型用の田植
機の苗載装置に関する。[Detailed description of the invention] "Industrial application field" The invention relates to a seedling mounting device of a rice transplanter for a large-sized multi-row such as a 6-row or 8-row.
「従来の技術」 苗載台を支持する支持枠は、支持枠に取付ける苗台シ
ューの取付位置精度を高めるために、比較的丈夫な一体
形構造の支持枠や、前記シューを取付ける上部枠のみを
丈夫な一体形とする支持枠に構成する必要がある。"Conventional technology" The support frame that supports the seedling mounting table is only a relatively durable one-piece support frame or the upper frame to which the shoe is attached, in order to increase the mounting position accuracy of the seedling stand shoes attached to the support frame. It is necessary to construct a support frame that is a strong integral type.
「考案が解決しようとする問題点」 しかし乍らこのような構成の場合、苗載台の条数増大
に伴って大型化すればする程、支持枠もその分強度の大
きなものを必要として重量を増大させ、この結果植付部
の全体重量を増大させるという欠点があった。"Problems to be solved by the invention" However, in the case of such a configuration, the larger the number of seedling stands and the larger the number of rows, the greater the strength of the supporting frame and the more the supporting frame is required. And, as a result, increase the overall weight of the planting portion.
「問題点を解決するための手段」 したがって本考案は、苗載台を支持する支持枠を左右
方向に横設する植付伝動ケース上に配備させる構造にお
いて、前記伝動ケースの左右略中央位置に立設させる門
形の中央フレームと、前記伝動ケースの左右両側位置に
それぞれ立設させる左右縦フレームと、前記中央フレー
ムと左右縦フレームの上部間をそれぞれ連結する上部ス
テーと、前記中央フレームの上部と左右縦フレームの下
部間をそれぞれ連結する斜めステーとで、前記支持枠を
構成したものである。"Means for solving the problem" Therefore, the present invention provides a structure in which a support frame for supporting a seedling mounting table is arranged on a planting transmission case horizontally arranged in the left-right direction. A gate-shaped central frame to be erected, left and right vertical frames respectively erected at both left and right positions of the transmission case, an upper stay connecting the upper portions of the central frame and the left and right vertical frames, and an upper part of the central frame And the slanting stays connecting the lower portions of the left and right vertical frames respectively constitute the support frame.
「作用」 而して本考案によれば、前記中央フレームと左右縦フ
レームのみを比較的丈夫なもので、また上部ステーと斜
めステーを強度を余り必要としない比較的細身形状のも
ので形成し得て、支持枠の強度を安定保持させた状態下
で全体重量の軽減化を可能にできる。According to the present invention, only the center frame and the left and right vertical frames are made of a relatively strong material, and the upper stay and the slanting stay are made of a relatively thin shape that does not require much strength. As a result, it is possible to reduce the overall weight while maintaining the strength of the support frame stably.

のバネ力でもってこの位置保持を図るものである。As shown in FIGS. 5 to 7, the first arm (37), which is in a vertically downward state when the seedlings (16a) are united, drives the motor (43) to loosen the wires (52a) (52b). At this time, the gasket (53) is rotated about 90 degrees outward about the first fulcrum shaft (36) by the extension action force of the gas spring (53) to move the seedling mounting body (16a) from the central seedling mounting body (16b). Pull outward and pull upward. When the first arm (37) rotates approximately 90 degrees and the upper and lower second fulcrum shafts (38) overlap on one vertical line (R), this shaft (38)
The seedling mounting body (16a) is pivoted downward by its own weight with its own weight, and is stored in a state of being bent at approximately 90 degrees on the back side outside the left and right ends of the seedling mounting base body (16b). When the motor (43) is driven to pull the wires (52a) (52b), the first arm (3) is pulled against the gas spring (53).
7) is returned to the vertical position again, and the seedling mount (16a) is
b) to the left and right sides, and after this combination, the spring (51)
This position is intended to be maintained by the spring force.

In the structure, a gate-shaped central frame (61) erected at substantially the right and left center positions of the transmission case (20a), and a left and right vertical frame (6) erected at both left and right positions of the transmission case (20a).
2) (63), upper stays (64) and (65) connecting the upper portions of the central frame (61) and the left and right vertical frames (62) and (63), respectively, and the upper and left and right portions of the central frame (61). Since the support frame (58) is constituted by the diagonal stays (66) and (67) connecting the lower portions of the vertical frames (62) and (63), the central frame (61) and the left and right vertical frames are formed. Only (62) and (63) can be made of relatively strong materials, and the upper stay (64) (65) and the slanting stays (66) (67) can be made of a relatively slender shape that does not require much strength. Therefore, a remarkable effect can be achieved, for example, the overall weight can be reduced while the strength of the support frame (58) is stably maintained.
