JP 2005-95053 A

上記従来技術のものは、粉粒体貯溜部及び繰出部が支持部材に沿って左右に移動する構成であるので、この左右移動機構が必要となり、構造が複雑になる。また、部分クラッチにより一部の苗植付装置の駆動を停止しても、粉粒体吐出装置は粉粒体を苗載台の全ての苗載部に吐出することになるので、粉粒体が無駄になる。仮に、粉粒体を無駄にしないために、部分クラッチの作動に連動して繰出部がその左右位置に応じて繰出を入切することが考えられるが、その制御機構は複雑なものになってしまう。   In the above prior art, since the powder storage part and the feeding part move to the left and right along the support member, this right / left movement mechanism is required, and the structure becomes complicated. Moreover, even if the driving of some seedling planting devices is stopped by the partial clutch, the granular material discharge device will discharge the granular material to all the seedling mounting portions of the seedling mounting stage. Is wasted. Temporarily, in order not to waste the granular material, it is conceivable that the feeding part is turned on and off according to the left and right positions in conjunction with the operation of the partial clutch, but the control mechanism becomes complicated. End up.

この発明は、上記課題を解決すべく次のような技術的手段を講じた。
すなわち、請求項１に係る発明は、左右に複数設けた苗載部（１１ｅ）に苗を載せて左右移動して苗を一株分づつ前記苗載部（１１ｅ）に対応する左右に複数設けた苗取出口（１１ｂ）へ供給する苗載台（１１）と、苗取出口（１１ｂ）の苗を取って植え付ける左右に複数設けた苗植付装置（１３）を備える苗植付部（６）を車体（１）に設け、粉粒体を貯溜する粉粒体貯溜部（１５）と該粉粒体貯溜部（１５）内の粉粒体を苗載台（１１）の苗載面の左右方向全幅にわたって所定量づつ繰り出す左右に複数設けた繰出部（１７）と該繰出部（１７）を駆動する各々のモータ（１９）を備えた粉粒体吐出装置（１８）を、支持フレーム（３８）により苗載台（１１）に支持させて設け、複数の苗植付装置（１３）のうちの一部の苗植付装置（１３）の駆動を停止する部分クラッチ（５１）を設け、該部分クラッチ（５１）の作動に連動して該部分クラッチ（５１）で停止した一部の苗植付装置（１３）に対応する苗載部（１１ｅ）に吐出する一部の繰出部（１７）のモータ（１９）を停止させる制御装置（５５）を設けた苗移植機とする。 In order to solve the above problems, the present invention has taken the following technical means.
That is, the invention according to claim 1 is provided with a plurality of seedlings placed on the left and right corresponding to the seedling placing part (11e) by placing the seedlings on the seedling placing parts (11e) provided on the left and right sides and moving left and right. A seedling planting section (6) provided with a seedling mounting base (11) to be supplied to the seedling outlet (11b) and a plurality of seedling planting devices (13) provided on the left and right sides for taking and planting seedlings from the seedling outlet (11b) ) Is provided on the vehicle body (1), and the granular material storage part (15) for storing the granular material and the granular material in the granular material storage part (15) are arranged on the seedling mounting surface of the seedling mounting base (11). A granular material discharge device (18) provided with a plurality of feeding portions (17) provided on the left and right sides that are fed out by a predetermined amount over the entire width in the left-right direction and each motor (19) that drives the feeding portion (17) is attached to a support frame ( 38) is supported by the seedling placing stand (11), and a part of the plurality of seedling planting devices (13) (13) 3) A partial clutch (51) for stopping driving is provided, and seedlings corresponding to some seedling planting devices (13) stopped by the partial clutch (51) in conjunction with the operation of the partial clutch (51) A seedling transplanting machine provided with a control device (55) for stopping the motor (19) of a part of the feeding section (17) discharged to the mounting section (11e).

従って、この苗移植機は、粉粒体吐出装置（１８）のモータ（１９）を駆動することにより苗載台（１１）上の苗の全面に粉粒体を吐出し、苗植付装置（１３）により苗取出口（１１ｂ）から一株分の苗及びその苗に吐出された粉粒体を取って圃場に供給し、圃場に苗を植え付けていくと共に粉粒体を散布していく。また、圃場での植付作業において植付条数を圃場の大きさに合わせて調整するとき、部分クラッチ（５１）で一部の苗植付装置（１３）の駆動を停止するが、制御装置（５５）によりこの停止した植付条に対応する苗載部（１１ｅ）上に繰り出す繰出部（１７）のモータ（１９）が停止する。   Therefore, this seedling transplanting machine discharges the granular material to the entire surface of the seedling on the seedling mounting base (11) by driving the motor (19) of the granular material discharging apparatus (18), and the seedling transplanting apparatus ( 13) The seedlings for one strain and the powder particles discharged to the seedlings are taken from the seedling outlet (11b) according to 13), supplied to the field, and the seedlings are planted and sprayed on the field. Moreover, when adjusting the number of planting strips according to the size of the field in the planting operation in the field, the drive of some seedling planting devices (13) is stopped by the partial clutch (51). Due to (55), the motor (19) of the feeding section (17) that feeds the seedling placement section (11e) corresponding to the stopped planting strip is stopped.

よって、各々のモータ（１９）を駆動することにより苗載台（１１）上の苗の全面に粉粒体を吐出するので、従来のように粉粒体貯溜部及び繰出部を左右移動させる左右移動機構が不要になり、粉粒体吐出装置（１８）の構成が簡潔になる。また、制御装置（５５）により部分クラッチ（５１）の作動に連動して停止した植付条に対応する苗載部（１１ｅ）上に繰り出す繰出部（１７）のモータ（１９）が停止する構成であるので、粉粒体を無駄に吐出させることを防止でき、コストダウンが図れると共に、部分クラッチ（５１）に連動してモータ（１９）を停止させるだけの構成であるため、その制御構成を簡単にできる。   Therefore, by driving each motor (19), the granular material is discharged to the entire surface of the seedling on the seedling placing stand (11), so that the left and right sides move the granular material storage part and the feeding part as in the prior art. A moving mechanism becomes unnecessary, and the structure of a granular material discharge apparatus (18) becomes simple. Moreover, the structure which the motor (19) of the feeding part (17) extended | stretched on the seedling mounting part (11e) corresponding to the planting strip stopped in response to the action | operation of the partial clutch (51) by the control apparatus (55) stops. Therefore, it is possible to prevent the powder particles from being discharged unnecessarily, the cost can be reduced, and the motor (19) is merely stopped in conjunction with the partial clutch (51). Easy to do.
