【発明の属する技術分野】
本発明は、側条施肥機のブロワスイッチに関する。
【0002】
【従来の技術】
従来、左右方向に多数配列した施肥機本体に、左右方向に伸延した送風パイプを介してブロワを連通させ、施肥機本体で計量した肥料をエア搬送するようにした側条施肥機がある。
【0003】
【発明が解決しようとする課題】
ところが、最近作業能率を上げるため、施肥機本体の数を増加する傾向にあり、このようすると、側条施肥機の横幅が大きくなって、圃場間の移動や格納に不便になる。
【0004】
そこで、前記送風パイプの一端に枢軸を設け、同枢軸にブロワを回動自在に取付けて、ブロワと送風パイプとを連通・分離可能に構成し、ブロワを内側に回動・格納して横幅を小さくすることが考えられるが、このようにすると、ブロワを格納した状態でも、誤操作等によりブロワが作動して動力を浪費したり、安全上の問題があった。
【0005】
【課題を解決するための手段】
そこで、本発明では、送風パイプの一端に枢軸を設けると共に、送風パイプと別体のブロワ取付具にブロワを同枢軸を中心として回動及び上下摺動自在となるべく取付けて、ブロワと送風パイプとを連通・分離可能に構成し、ブロワと送風パイプとの連通・分離に連動してON/OFFするスイッチ本体を枢軸支持体に設け、しかも、上記スイッチ本体のアクチュエータと対向する位置に板バネの作動端部を接離可能に配設すると共に、板バネの作動端部に連続した上方湾曲部をブロワ取付具の孔から出没自在に設け、ブロワ取付具には、同孔を進退作動により開閉する押圧体を設け、ブロワと送風パイプとを連通させた際に、押圧体により板バネの上方湾曲部降下作動させて、作動端部によりスイッチ本体のアクチュエータを押圧することによりスイッチ本体をONさせ、しかも、ブロワと送風パイプとを連通した状態で、押圧体の退去作動により押圧体が板バネを押圧しないようにすることによって、板バネをアクチュエータから離反させて、スイッチ本体のアクチュエータを押圧解除して、スイッチ本体をOFFさせるように構成し、かかる構成により、ブロワと送風パイプとの連通操作をすることによってブロワ作動可能となり、他方、押圧体を摺動操作することによってブロワが作動を停止するようにしたことを特徴とする側条施肥機のブロワスイッチを提供することとした。
【0009】
【発明の実施の形態】
本実施例では、送風パイプの一端に枢軸を設けると共に、送風パイプと別体のブロワ取付具にブロワを同枢軸を中心として回動・格納及び上下摺動自在となるべく取付けて、ブロワと送風パイプとを連通・分離可能に構成し、ブロワと送風パイプとの連通・分離に連動してON/OFFすることによりブロワの作動を制御するスイッチ本体を枢軸支持体に設け、しかも、上記スイッチ本体のアクチュエータと対向する位置に板バネの作動端部を接離可能に配設すると共に、板バネの作動端部に連続した上方湾曲部をブロワ取付具の孔から出没自在に設け、ブロワ取付具には、同孔を進退作動により開閉する押圧体を設け、ブロワと送風パイプとを連通させた際に、押圧体により板バネの上方湾曲部降下作動させて、作動端部によりスイッチ本体のアクチュエータを押圧することによりスイッチ本体をONさせ、しかも、ブロワと送風パイプとを連通した状態で、押圧体の退去作動により押圧体が板バネを押圧しないようにすることによって、板バネをアクチュエータから離反させて、スイッチ本体のアクチュエータを押圧解除して、スイッチ本体をOFFさせるように構成し、かかる構成により、ブロワと送風パイプとの連通操作をすることによってブロワ作動可能となり、他方、押圧体を摺動操作することによってブロワが作動を停止するようにしている。

【0020】
また、主フレーム31の外側端に、上下方向に伸延した回動軸35を介してブロワ36を前方向に回動自在に取付けると共に、副フレーム32の外側端にブロワ36を固着して、主フレーム31側のブロワ36をゴムや軟質プラスチック等の伸縮及び屈折可能の柔軟素材にて形成した送風パイプ37を介し、各施肥機本体30の計量部38の下部に連通している。
【0021】

【0023】
図4〜図8は、ブロワ36の送風パイプ37への取付構造を示しており、送風パイプ37の一側端部前側面に、上下板50a,50b 及び内側板50c よりなる略箱形状の枢軸支持体50を前方向に突設し、同枢軸支持体50に上下方向に伸延した枢軸51を立設する一方、ブロワ36のファンケース52の前面に、板金製側面視略コ字形状のブロワ取付具53を取付け、同ブロワ取付具53の内側端部に上記枢軸51を挿通して、同枢軸51を中心としてブロワ36を回動及び上下摺動自在に装着している。

【0026】
図9〜図11は、ブロワスイッチSを示しており、同ブロワスイッチSは、前記枢軸支持体50の上下板50a,50b 間の内側板50c にスイッチ本体70を取付け、同スイッチ本体70に上方に湾曲した板バネ71の固定端部71a を固着して、同板バネ71の上方湾曲部71b を枢軸支持体50の上面に形成した矩形孔73から上方に突出させ、同板バネ71の作動端部71c の下面を、スイッチ本体70のアクチュエータ74に所定間隙を保持して対向させている。
【0027】
一方、ブロワ36を送風パイプ37に連通させた状態で、前記矩形孔73に対向する位置のブロワ取付具53に長方形孔75を形成すると共に、ブロワ取付具53の上面にガイド体76を設けて、同ガイド体76とブロワ取付具53上面との間隙を、略L字形状に屈折した板状の押圧体77を摺動自在に挿通させて、上記長方形孔75の上面を閉塞・開放可能としている。
【0028】
本発明の実施例は上記のように構成されており、ブロワ36を送風パイプ37に連通させた状態では、図9で示すように、長方形孔75を閉塞した押圧体77が板バネ71の上方湾曲部71b を下方に押圧し、同板バネ71の一端部でアクチュエータ74を押圧し、スイッチ本体70をONさせて、ブロワ36を作動させる。
【0029】
また、ブロワ36を格納するために、同ブロワ36を上方に摺動させると、図10で示すように、板バネ71から押圧体77が離れて、板バネ71が上方に移動し、同板バネ71がアクチュエータ74から離れ、スイッチ本体70をOFFして、ブロワ36の作動を停止させる。
【0030】
更に、ブロワ36を送風パイプ37に連通させた状態であっても、図11で示すように、押圧体77を摺動させて長方形孔75を開放すると、押圧体77が板バネ71を押圧しなくなり、スイッチ本体70をOFFするので、本ブロワスイッチSでメインスイッチとしての作用を兼用することができる。
【0031】
また、スイッチ本体70が枢軸支持体50の上下板50a,50b 間の内側板50c に取付けられているので、スイッチ本体70が保護されると共に、異物との接触による誤作動が防止されている。
【0032】
【発明の効果】
本発明によれば次のような効果を得ることができる。
【0033】
請求項1記載の発明では、送風パイプの一端に枢軸を設けると共に、送風パイプと別体のブロワ取付具にブロワを同枢軸を中心として回動及び上下摺動自在となるべく取付けて、ブロワと送風パイプとを連通・分離可能に構成し、ブロワと送風パイプとの連通・分離に連動してON/OFFするスイッチ本体を枢軸支持体に設け、しかも、上記スイッチ本体のアクチュエータと対向する位置に板バネの作動端部を接離可能に配設すると共に、板バネの作動端部に連続した上方湾曲部をブロワ取付具の孔から出没自在に設け、ブロワ取付具には、同孔を進退作動により開閉する押圧体を設け、ブロワと送風パイプとを連通させた際に、押圧体により板バネの上方湾曲部降下作動させて、作動端部によりスイッチ本体のアクチュエータを押圧することによりスイッチ本体をONさせ、しかも、ブロワと送風パイプとを連通した状態で、押圧体の退去作動により押圧体が板バネを押圧しないようにすることによって、板バネをアクチュエータから離反させて、スイッチ本体のアクチュエータを押圧解除して、スイッチ本体をOFFさせるように構成し、かかる構成により、ブロワと送風パイプとの連通操作をすることによってブロワ作動可能となり、他方、押圧体を摺動操作することによってブロワが作動を停止するようにしたことによって、ブロワを格納した際に、誤操作などによるブロワの無駄な作動を防止して、動力の無駄と安全性の低下とを防止することができ、また、簡単な構造でありながら、ブロワを格納した際にブロワの作動を自動的に停止させることができ、さらに、ブロワを送風パイプに連通した状態でも、スイッチ本体をOFFすることができるので、同ブロワスイッチでメインスイッチを兼用することができ、構造を簡単にすることができる。

Further, when storing the blower 36, the blower 36 is pivoted forward while sliding upward so that the motor part 59 of the blower 36 does not interfere with the blower pipe 37, and the pivot support 50 is inserted. The bolt 57 with the knob is screwed onto a nut 60 provided on the blower attachment 53 to fix the blower 36 in the retracted state (FIGS. 7 and 8). In the figure, 61 is a suction cylinder of the blower 36, and 62 is a filter.
[0026]
9 to 11 show a blower switch S. The blower switch S has a switch body 70 attached to an inner plate 50c between upper and lower plates 50a and 50b of the pivot support 50, and the switch body 70 has an upper portion. The fixed end portion 71a of the plate spring 71 curved in the direction is fixed, and the upper curved portion 71b of the plate spring 71 is protruded upward from the rectangular hole 73 formed in the upper surface of the pivot support 50, and the operation of the plate spring 71 is The lower surface of the end 71c is opposed to the actuator 74 of the switch body 70 with a predetermined gap.
[0027]
On the other hand, while the blower 36 is in communication with the blower pipe 37, a rectangular hole 75 is formed in the blower attachment 53 at a position facing the rectangular hole 73, and a guide body 76 is provided on the upper surface of the blower attachment 53. The upper surface of the rectangular hole 75 can be closed and opened by slidably inserting a plate-like pressing body 77 refracted into a substantially L shape into the gap between the guide body 76 and the upper surface of the blower fixture 53. Yes.
[0028]
The embodiment of the present invention is configured as described above. In the state where the blower 36 is communicated with the blower pipe 37, as shown in FIG. The bending portion 71b is pressed downward, the actuator 74 is pressed by one end of the leaf spring 71, the switch body 70 is turned on, and the blower 36 is operated.
[0029]
Further, when the blower 36 is slid upward to store the blower 36, as shown in FIG. 10, the pressing body 77 is separated from the leaf spring 71, and the leaf spring 71 moves upward. The spring 71 moves away from the actuator 74, turns off the switch body 70, and stops the operation of the blower 36.
[0030]
Furthermore, even when the blower 36 is in communication with the blower pipe 37, as shown in FIG. 11, when the pressing body 77 is slid to open the rectangular hole 75, the pressing body 77 presses the leaf spring 71. Since the switch body 70 is turned off, the blower switch S can be used as the main switch.
[0031]
Further, since the switch body 70 is attached to the inner plate 50c between the upper and lower plates 50a, 50b of the pivot support 50, the switch body 70 is protected and malfunction due to contact with foreign matter is prevented.
[0032]
【The invention's effect】
According to the present invention, the following effects can be obtained.
[0033]
In the invention of claim 1, wherein, Rutotomoni a pivot provided at one end of the air pipe, a blower to the blower fitting of the air pipe and another member as much as possible mounted freely to pivoting and vertically sliding around the same pivot, blower The switch body is configured to be able to communicate / separate between the blower pipe and the blower and the blower pipe to communicate with / separate, and a switch body that is turned ON / OFF is provided on the pivot support , and the switch body is opposed to the actuator. The operating end of the leaf spring is disposed so as to be able to contact and separate, and an upward curved portion continuous with the operating end of the leaf spring is provided so as to be able to protrude and retract from the hole of the blower mounting tool, and the blower mounting tool has the same hole. A pressing body that opens and closes by advancing and retreating operation is provided, and when the blower and the blower pipe are communicated , the upper curved portion of the leaf spring is lowered by the pressing body, and the actuator of the switch body is pressed by the operating end. The switch body is turned on, and the leaf spring is separated from the actuator by preventing the pressing body from pressing the leaf spring by the withdrawal operation of the pressing body in a state where the blower and the air pipe are in communication. The switch body is pressed to release the switch body , and the switch body is turned off . With this configuration, the blower can be operated by communicating with the blower and the air pipe , while the pressure body is slid. As a result, the blower stops operating, so that when the blower is retracted, it is possible to prevent wasteful operation of the blower due to erroneous operations, etc., and to prevent waste of power and deterioration of safety. in addition, with a simple structure, it is possible to automatically stop the operation of the blower when storing the blower, further, Even when communicating with the lower air blowing pipe, it is possible to turn OFF the switch body, can be used also the main switch at the same blower switch, it is possible to simplify the structure.
