Abstract

<P>PROBLEM TO BE SOLVED: To solve the problems of ineffective conventional cross cultivation methods for paddy fields comprising the lack in effective weeding result, the hard labor to pluck weeds by hand, the entanglement of foreign materials such as grass and root to a vertical shaft rotary blade also in mechanical weeding to lower efficiency and the damage to young rice plant. <P>SOLUTION: The subject rotary blade has a plurality of blades fixed to the outer surface of a conical body in an umbrella form. The blade is smoothly rotatable even around a vertical shaft while preventing the entanglement of foreign materials such as grass and root. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【0001】
【発明が属する技術分野】
本発明は田面株間を羽根を有する左右一対の傘条構造体が土と接しながら進行する過程で回転が生じ、有する羽根で連続的に株間の除草をする水田用株間除草回転羽根に関するものである。
【0002】
【従来の技術】
中央に傾斜した一対の軸に複数の棒状、又は帯状の、先端が上向きを成したる羽根が土と接しながら進行することで回転し、構造体羽根の遠心力で除草していた。
【0003】
【発明が解決しようとする課題】
回転羽根のそれぞれの羽根の先端が全て上向きを成している事で土中を回転しながらの進行過程に異物が絡み、堆積していき幼い稲を倒したり、堆積した異物を作業途中に取り除かなければならない等、除草本来の機能を発揮できないという問題点がある。
【0004】
【課題を解決するための手段】
円錐堆状外面に複数の羽根を傘状に取付け、更に直線状に一体化することで全ての羽根が下向きになり、異物の絡みが解消できる回転羽根を提供することにより上記課題を解決したものである。
【0005】
【実施例】
本発明の水田用株間除草回転羽根は図1に示されるように円錐堆状外面1に軸2を介し、円錐堆状外面1に傘状に複数の羽根3を複数枚、固着したものである。
【0006】
次に動作について説明する。図2に示されるように水田用株間除草回転羽根は、中心に傾斜した左右一対で構成し、稲の条を挟み、傘状に複数の羽根を有する構造体の下端中心部が土と接触することで回転しながら進行する。
【0007】
水田用株間除草回転羽根は図3に示されるように傘状に複数の羽根を有する構造体の羽根aと羽根bから成るスペースの土を左右一対の相反する回転で、左右対称に、外から中へ、中から外へ移動させ、移動した土に生えている草を取り除くことになる。
【0008】
【発明の効果】
以上のように請求項1記載の説明によれば、円錐堆状外面に傘状に羽根を複数枚配した形状により株間の除草を行うことができ、また、請求項2記載の説明によれば円錐堆状外面に傘状に有する羽根が全て下方に直線状に開いているため、草や根等の異物の絡みが無く、除草の確実性を更に高めることができる。

[Technical field to which the invention belongs]
The present invention relates to a paddy rice field weeding rotary blade that rotates in the process of a pair of left and right umbrella structures having blades moving in contact with soil, and continuously weeds between the rice with the blades. .
[0002]
[Prior art]
A plurality of rod-shaped or band-shaped blades with the tip facing upwards rotate on a pair of shafts inclined in the center, and the blades rotate while being in contact with the soil, and are weeded by the centrifugal force of the structure blades.
[0003]
[Problems to be solved by the invention]
Because the tip of each blade of the rotating blades is all upward, foreign matter is entangled in the progressing process while rotating in the soil, it accumulates and falls down the young rice, or removes the accumulated foreign matter during the work There is a problem that the original function of weeding cannot be exhibited.
[0004]
[Means for Solving the Problems]
The above problem has been solved by providing a rotating blade that attaches a plurality of blades to a cone-shaped outer surface in an umbrella shape and further integrates them into a straight line so that all the blades face downward and entanglement of foreign matter can be eliminated. It is.
[0005]
【Example】
As shown in FIG. 1, the paddy field weeding rotary blade of the present invention is formed by fixing a plurality of blades 3 in an umbrella shape on a cone-like outer surface 1 via a shaft 2 and on the cone-like outer surface 1. .
[0006]
Next, the operation will be described. As shown in FIG. 2, the paddy field weeding rotary blade is composed of a pair of right and left slanted at the center, sandwiching the rice strip, and the bottom center of the structure having a plurality of blades in an umbrella shape is in contact with the soil It advances while rotating.
[0007]
As shown in FIG. 3, the paddy field weeding rotary blade is a pair of left and right reciprocating rotations in the soil of the space consisting of blades a and b of a structure having a plurality of blades in an umbrella shape, and symmetrically from the outside. Move in and out, and remove the grass that grows on the moved soil.
[0008]
【The invention's effect】
As described above, according to the description of claim 1, weeding between the strains can be performed by a shape in which a plurality of blades are arranged in an umbrella shape on the outer surface of the cone, and according to the description of claim 2. Since all of the umbrella-shaped blades on the outer surface of the conical stack are opened downward in a straight line, there is no entanglement of foreign matters such as grass and roots, and the reliability of weeding can be further enhanced.
[Brief description of the drawings]
BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is an external view showing a configuration of an inter- stock weed rotary blade for paddy fields.
FIG. 2 is a process diagram seen from the side showing the working operation of a paddy field inter-weed weed rotary blade.
FIG. 3 is a process diagram seen from above showing the operation of the inter-strain weeding rotary blade for paddy fields.
FIG. 4 is a cross-sectional view of an inter- stock weed rotary blade for paddy fields.
