Description

本発明は乗用型や歩行型の田植機に備えられる苗植付装置の苗のせ台において、苗のせ面に載置された苗が所定量よりも少なくなったことを検出する構造に関する。   The present invention relates to a structure for detecting that the number of seedlings placed on a seedling placing surface is less than a predetermined amount in a seedling placing stand of a seedling planting device provided in a riding type or walking type rice transplanter.

苗植付装置の苗のせ台は一般に、複数の苗のせ面と隣接する苗のせ面の間に位置する仕切り部とを備えて構成されている。例えば特許文献１に開示されているように、仕切り部（特許文献１の図１９及び図２０中の２２ｂ）の下方に、検出スイッチ（特許文献１の図１９及び図２０中の５０Ｄ）を備え、仕切り部の内部に右及び左の接触体（特許文献１の図１９及び図２０中の５０Ａ，５０Ｂ）を備えて、右及び左の接触体を仕切り部から右及び左の横方に突出させたものがある。   The seedling platform of the seedling planting apparatus is generally configured to include a plurality of seedling setting surfaces and a partition portion positioned between the adjacent seedling setting surfaces. For example, as disclosed in Patent Document 1, a detection switch (50D in FIGS. 19 and 20 of Patent Document 1) is provided below the partition (22b in FIGS. 19 and 20 of Patent Document 1). The right and left contact bodies (50A and 50B in FIGS. 19 and 20 of Patent Document 1) are provided inside the partition part, and the right and left contact bodies protrude right and left laterally from the partition part. There is something that let me.

これにより、特許文献１の構造によれば、苗のせ面に苗が載置されていると、苗により右及び左の接触体が仕切り部の内部に押し込まれている。苗の植え付けに伴って苗のせ面に載置された苗が少なくなり、右又は左の接触体の位置よりも苗が下方に移動すると、右又は左の接触体が仕切り部から右又は左の横方に突出し、右又は左の接触体の動作が検出スイッチに伝達される（特許文献１の図２０参照）。
以上のように、２つの苗のせ面（仕切り部の右隣及び左隣の苗のせ面）の苗が所定量よりも少なくなったことを、一つの検出スイッチによって検出することができる。 Thereby, according to the structure of patent document 1, when the seedling is mounted on the seedling surface, the right and left contact bodies are pushed into the partition by the seedling. As the seedlings are placed on the seedling surface as the seedlings are planted and the seedlings move downward from the position of the right or left contact body, the right or left contact body is moved from the partition to the right or left side. It protrudes sideways and the operation of the right or left contact body is transmitted to the detection switch (see FIG. 20 of Patent Document 1).
As described above, it is possible to detect with one detection switch that the number of seedlings on the two seedling surfaces (the right and left adjacent seedling surfaces of the partition portion) is less than a predetermined amount.

特開２００１−２７５４２２号公報（図１９及び図２０）JP 2001-275422 A (FIGS. 19 and 20)

苗のせ台において仕切り部の横幅は狭いものなので、特許文献１の構造のように仕切り部の内部に右及び左の接触体を備えると、仕切り部の内部に検出スイッチを備えることが困難になる。これにより、特許文献１の構造によると、右及び左の接触体の動作方向（苗のせ面に沿った左右方向）（特許文献１の図１９及び図２０参照）に、検出スイッチが存在しない状態となっているので、右又は左の接触体が右又は左の横方に突出した場合、右又は左の接触体の苗のせ面に沿った左右方向の動作を、カム機構（特許文献１の図２０中の５０ａ，５０ｃ）により苗のせ面の下方の動作に変換して（方向を９０°変換して）、検出スイッチに伝達するように構成している。   Since the width of the partition part is narrow in the seedling table, if the right and left contact bodies are provided inside the partition part as in the structure of Patent Document 1, it is difficult to provide the detection switch inside the partition part. . Thus, according to the structure of Patent Document 1, there is no detection switch in the operation direction of the right and left contact bodies (the left-right direction along the seedling surface) (see FIGS. 19 and 20 of Patent Document 1). Therefore, when the right or left contact body protrudes laterally to the right or left, the left or right movement along the seedling surface of the right or left contact body is controlled by a cam mechanism (see Patent Document 1). 20a and 50c in FIG. 20 is converted into an operation below the seedling surface (the direction is changed by 90 °) and transmitted to the detection switch.

前述のように、特許文献１の構造によると、右又は左の接触体の苗のせ面に沿った左右方向の動作を、苗のせ面の下方の動作に変換して（方向を９０°変換して）、検出スイッチに伝達するように構成しているので、泥や土等が付着し易い苗のせ台において、検出スイッチによる検出の確実性と言う面で改善の余地がある。
本発明は苗植付装置の苗のせ台において、２つの苗のせ面（仕切り部の右隣及び左隣の苗のせ面）の苗が所定量よりも少なくなったことを、一つの検出スイッチによって検出するように構成する場合、検出スイッチによる検出が確実に行われるように構成することを目的としている。 As described above, according to the structure of Patent Document 1, the left-right movement along the seedling surface of the right or left contact body is converted into the motion below the seedling surface (the direction is changed by 90 °). Therefore, there is room for improvement in terms of the certainty of detection by the detection switch in the seedling platform where mud, soil, etc. are likely to adhere.
According to the present invention, in the seedling platform of the seedling planting device, the single seeding switch indicates that the number of seedlings on the two seedling placement surfaces (the right and left seedling placement surfaces of the partition part) is less than a predetermined amount. When configured to detect, the object is to ensure that detection by a detection switch is performed.
