Description

本発明は、肥料などの粉粒体を散布する散布機などにおいて粉粒タンク内の粉粒体を攪拌するための粉粒タンクの攪拌装置に関するものである。   The present invention relates to a stirring device for a powder tank for stirring powder particles in a powder tank in a spreader for spraying powder particles such as fertilizer.

従来のこの種の粉粒タンクの攪拌装置は、粉粒タンクの落下口付近に回転あるいは往復動する部材を配備して、この部材により落下口に落ちる手前の粉粒体を攪拌している。   A conventional stirring device for this type of powder tank is provided with a member that rotates or reciprocates in the vicinity of the dropping port of the powder tank, and this member is used to stir the powder that is in front of the dropping port.

解決しようとする問題は、粉粒タンク内の粉粒体は全体の流れとしてタンクの下部内側面に沿って（ガイドされて）落下口に向かって自然落下するのであるが、従来のものは前記したように落下口に落ちる手前で粉粒体を攪拌しているので、粉粒体の中でも特に肥料はタンク内で湿り気を帯びると固まりやすくなってタンクの下部内側面に沿って自然落下しにくくなることに攪拌の機能を効果的に果たせず、粉粒体（肥料）がタンクの下部内側面の部分で固まってタンク内での粉粒体（肥料）の全体の流れが悪くなり粉粒体（肥料）が落下口から落下しにくくなるという点である。   The problem to be solved is that the granular material in the granular tank naturally falls as a whole flow along the lower inner surface of the tank (guided) toward the dropping port. As the powder is agitated before it falls into the drop mouth, fertilizer, especially in the powder, tends to harden when wet in the tank and is difficult to fall naturally along the lower inner surface of the tank. In other words, the function of stirring cannot be performed effectively, and the powder (fertilizer) is solidified at the lower inner surface of the tank and the entire flow of the powder (fertilizer) in the tank becomes worse. (Fertilizer) is difficult to fall from the drop opening.

本発明は、粉粒タンク内に回転可能に貫挿支持される駆動軸と、この駆動軸の両側方にあって粉粒タンクの下部内側面近くに左右対称形の羽根のように設けられて前記下部内側面に向かってそれぞれ往復揺動する左右二枚の攪拌部材と、この攪拌部材を前記駆動軸によってそれぞれ往復揺動させるための伝動部材とを備えたことを特徴とする。   The present invention is provided like a symmetrical blade on a drive shaft that is rotatably inserted and supported in a powder tank, and on both sides of the drive shaft near the lower inner surface of the powder tank. It is characterized by comprising two left and right stirring members that reciprocally swing toward the lower inner surface, and a transmission member that reciprocally swings the stirring members by the drive shaft.

本発明は、粉粒体の中でも特に肥料が湿り気を帯びて固まりやすいタンクの下部内側面の部分で攪拌部材が動作するようにしたので、タンク内の最も攪拌が必要とされる部分で攪拌機能が十分に発揮されるようになって，粉粒体（肥料）のタンク内での自然落下が損なわれることなく促進されるという効果がある。   In the present invention, the stirring member operates in the lower inner surface portion of the tank where the fertilizer tends to get wet and harden among the granular materials. Is fully exerted, and there is an effect that the natural fall of the granular material (fertilizer) in the tank is promoted without being impaired.

粉粒タンクの下部内側面近くで左右二枚の攪拌部材を往復揺動させることにより、実現した。   This was realized by reciprocally swinging the two left and right stirring members near the lower inner surface of the powder tank.

図１は本発明装置の一実施例を示す概略図、図２は図１を右からみた図、図３は図１の伝動部材Ａの動きを説明する図である。   FIG. 1 is a schematic view showing an embodiment of the device of the present invention, FIG. 2 is a view of FIG. 1 viewed from the right, and FIG. 3 is a view for explaining the movement of the transmission member A of FIG.

図において、１は粉粒タンク、２は粉粒タンク１の落下口１ａ近くに回転可能に貫挿して支持した駆動軸Ａ、３は駆動軸Ａ２に駆動力を入力するための駆動部Ａ、４は駆動軸Ａ２に取り付けた偏心円板、５は偏心円板４に回転可能に被着した環体部５ａとこれよりＴ字状に延びるアーム部５ｂとからなる伝動部材Ａ、６は伝動部材Ａ５のＴ字状の左右両端側にピン７，７によりそれぞれ枢着した左右二枚の攪拌部材で、粉粒タンク１の対向する下部内側面１ｂ，１ｂのそれぞれの近くに左右対称形の羽根のように設けられて下部内側面１ｂ，１ｂに向かってそれぞれ往復揺動するようになっている。   In the figure, 1 is a powder tank, 2 is a drive shaft A that is rotatably inserted and supported near the drop port 1a of the powder tank 1, and 3 is a drive unit A for inputting drive force to the drive shaft A2. Reference numeral 4 denotes an eccentric disc attached to the drive shaft A2, 5 denotes a transmission member A, 6 comprising an annular portion 5a rotatably attached to the eccentric disc 4 and an arm portion 5b extending in a T-shape therefrom. Two left and right agitating members pivotally attached to the left and right ends of the A-shaped member A5 by means of pins 7 and 7, respectively, and are symmetrical in the vicinity of the opposed lower inner side surfaces 1b and 1b of the powder tank 1. It is provided like a blade and reciprocally swings toward the lower inner surface 1b, 1b.

今、駆動軸Ａ２を駆動部Ａ３により回転させると、その偏心円板４の回転によりこれとは滑って回動してほぼその位置（姿勢）を保持しながら偏心力によって公転する，つまり図３中点線で示すように公転する環体部５ａにより伝動部材Ａ５は往復揺動するので、この伝動部材Ａ５の往復揺動，つまり図３中点線で示す動きとか図１中想像線で示す動きにより、各攪拌部材６は図１中想像線で示すように下部内側面１ｂ，１ｂに向かってそれぞれ往復揺動する。   Now, when the drive shaft A2 is rotated by the drive unit A3, the eccentric disk 4 slides and rotates due to the rotation of the eccentric disk 4, and revolves by the eccentric force while maintaining its position (posture). As shown by the middle dotted line, the transmission member A5 is reciprocally swung by the revolving ring body portion 5a. Therefore, the transmission member A5 is reciprocally swung, that is, by the movement indicated by the dotted line in FIG. Each stirring member 6 reciprocally swings toward the lower inner side surfaces 1b and 1b as indicated by phantom lines in FIG.

このように各攪拌部材６は下部内側面１ｂ，１ｂに向かってそれぞれ往復揺動するので、粉粒タンク１内で最も固まりやすい下部内側面１ｂ，１ｂにある粉粒体が最も良く攪拌されることになって、粉粒タンク１内での粉粒体全体の流れがスムーズになり、粉粒体は落下口１ａからスムーズに落下する。   Thus, since each stirring member 6 reciprocally swings toward the lower inner side surfaces 1b and 1b, the powder particles on the lower inner side surfaces 1b and 1b that are most likely to harden in the powder tank 1 are best stirred. As a result, the flow of the whole granular material in the granular particle tank 1 becomes smooth, and the granular material falls smoothly from the dropping port 1a.

攪拌部材６の形状は粉粒タンク１の形状，構造に合わせて適宜決めれば良いし、できれば図示するように抵抗の少ない線状体で構成するのが良い。   The shape of the agitating member 6 may be appropriately determined in accordance with the shape and structure of the powder tank 1 and, if possible, it may be constituted by a linear body with low resistance as illustrated.

図４は本発明装置の他の実施例を示す概略図、図５は図４を右からみた図、図６は図５の駆動部Ｂを示す図、図７は図４の伝動部材Ｂの動きを説明する図であり、各図中前記した実施例１のものと同一または相当部分には同一符号を付して説明を省略する。   4 is a schematic view showing another embodiment of the apparatus of the present invention, FIG. 5 is a view of FIG. 4 as viewed from the right, FIG. 6 is a view showing the drive section B of FIG. It is a figure explaining a movement, The same code | symbol is attached | subjected to the part which is the same as that of Example 1 mentioned above in each figure, or an equivalent part, and description is abbreviate | omitted.

図において、８は粉粒タンク１の落下口１ａ近くに回転可能に貫挿して支持した駆動軸Ｂ、９は駆動軸Ｂ８に固着されて揺動するリンク部９ａとこれにピン１０により接続されてＴ字状に延びるアーム部９ｂとからなる伝動部材Ｂ、１１は駆動軸Ｂ８に設けた駆動アーム、１２は駆動アーム１１を一定の角度で往復回転させるための駆動部Ｂである。   In the figure, reference numeral 8 denotes a drive shaft B that is rotatably inserted and supported near the dropping port 1a of the particle tank 1, and 9 is connected to a link portion 9a that is fixed to the drive shaft B8 and swings with a pin 10. The transmission members B and 11 comprising the arm portion 9b extending in a T-shape are drive arms provided on the drive shaft B8, and 12 is a drive portion B for reciprocally rotating the drive arm 11 at a constant angle.

今、駆動部Ｂ１２の回転力により駆動アーム１１が一定の角度で往復回転すると、これに伴って駆動軸Ｂ８が一定の角度で往復回転するので、伝動部材Ｂ９のリンク部９ａが図７に示すように往復回転してアーム部９ｂが往復揺動，つまり図７中点線で示す動きとか図４中想像線で示す動きをする。この動きにより、各攪拌部材６は図４中想像線で示すように下部内側面１ｂ，１ｂに向かってそれぞれ往復揺動する。   Now, when the drive arm 11 is reciprocated at a constant angle by the rotational force of the drive unit B12, the drive shaft B8 is reciprocated at a constant angle, so that the link 9a of the transmission member B9 is shown in FIG. Thus, the arm portion 9b reciprocally swings, that is, moves indicated by a dotted line in FIG. 7 or moves indicated by an imaginary line in FIG. By this movement, each stirring member 6 reciprocally swings toward the lower inner side surfaces 1b and 1b as indicated by phantom lines in FIG.

このように各攪拌部材６は下部内側面１ｂ，１ｂに向かってそれぞれ往復揺動するので、粉粒タンク１内で最も固まりやすい下部内側面１ｂ，１ｂにある粉粒体が最も良く攪拌されることになって、粉粒タンク１内での粉粒体全体の流れがスムーズになり、粉粒体は落下口１ａからスムーズに落下する。   Thus, since each stirring member 6 reciprocally swings toward the lower inner side surfaces 1b and 1b, the powder particles on the lower inner side surfaces 1b and 1b that are most likely to harden in the powder tank 1 are best stirred. As a result, the flow of the whole granular material in the granular particle tank 1 becomes smooth, and the granular material falls smoothly from the dropping port 1a.

なお、本実施例のように駆動軸Ｂ８が一定角度で往復回転するものでは伝動部材Ｂ９をリンク部９ａ，アーム部９ｂとで構成し、また前記した実施例１のように駆動軸Ａ２が回転するものでは伝動部材Ａ５を偏心円板４に被着した環体部５ａとアーム部５ｂとで構成したが、これら伝動部材の構成はこれらのものに限らないは勿論である。   If the drive shaft B8 reciprocates at a constant angle as in this embodiment, the transmission member B9 is composed of a link portion 9a and an arm portion 9b, and the drive shaft A2 rotates as in the first embodiment. In this case, the transmission member A5 is composed of the ring body portion 5a and the arm portion 5b attached to the eccentric disc 4, but the configuration of these transmission members is not limited to these.

本発明は、肥料に限らず，粉粒体を散布するものに広く活用できる。   The present invention is not limited to fertilizers, and can be widely used for those spraying granular materials.
