Abstract

<P>PROBLEM TO BE SOLVED: To provide a smoothly moving snow removing edge capable of freely getting over recessed and projecting parts of a snow removing face to perform snow removing work, while overcoming a problem that, since the tip edge of a blade, a bucket or the like of a snow removing device of conventional mechanical snow removing equipment is sharp or square, the tip edge is prone to abut against the step of a snow removing face and a construction, thus causing a probability that the construction and the snow removing device are damaged. <P>SOLUTION: The tip edge of the snow removing device such as the blade and the bucket of the mechanical snow removing equipment is formed into such a shape that has a circular arc with respect to the ground surface. Snow can be efficiently pushed out and removed because the snow compressed in an edge tip having the circular arc acts as a part of the snow removing device as a virtual edge. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

この発明は、機械式除雪機のブレードやバケット等除雪装置の先端エッジを、地面に向かって後方に円弧を有する形に成形した、円滑移動除雪エッジに関するものである。 The present invention relates to a smooth-moving snow removal edge in which a tip edge of a snow removal device such as a blade or bucket of a mechanical snow removal machine is formed into a shape having an arc on the rear side toward the ground.

従来、機械式除雪機のブレードやバケット等除雪装置の先端エッジは、鋭いか角張っていた。 Conventionally, the tip edge of a snow removal device such as a blade or bucket of a mechanical snow remover has been sharp or angular.

これは次のような問題点があった。
（イ）機械式除雪機のブレードやバケット等除雪装置先端の金属エッジは、圧雪の切削を可能とさせるため、鋭いか角張っていた。このため、作業時は除雪装置の先端エッジを段差へ突き当てぬように、また、未舗装部分の砂利の巻き込みなどを防止するように、除雪装置と除雪面の間隔を確保するための、こまめな調整が必要であった。
（ロ）上記（イ）の理由により、除雪作業は、あらかじめ除雪面の段差や構造物などの配置情報を熟知しておく必要があった。
（ハ）金属製のエッジを取り付けた除雪装置は、段差や構造物に突き当たると、構造物や除雪装置を損傷させる恐れがあった。
（ニ）機械式除雪機のブレードやバケット等除雪装置先端の、合成樹脂製や合成ゴム製エッジは、段差や構造物に突き当たると、エッジを破損する恐れがあった。
本発明は、以上のような欠点を解消するためになされたものである。This has the following problems.
(A) The metal edge at the tip of the snow removal device such as a blade or bucket of a mechanical snow remover was sharp or angular in order to enable the cutting of compressed snow. For this reason, during work, do not allow the tip edge of the snow removal device to bump into the step, and to prevent the gravel of unpaved parts from getting caught, etc. Adjustments were necessary.
(B) For the reason of (b) above, it is necessary for snow removal work to be familiar with the arrangement information of the step and structure of the snow removal surface in advance.
(C) When a snow removal device with a metal edge hits a step or a structure, the structure or the snow removal device may be damaged.
(D) The edge made of a synthetic resin or a synthetic rubber at the tip of a snow removal device such as a blade or bucket of a mechanical snow remover may be damaged if it hits a step or a structure.
The present invention has been made to eliminate the above-described drawbacks.

機械式除雪機のブレードやバケット等除雪装置（２）の先端エッジ（１）を、地面に向かって後方に円弧を有する形に成形することにより解決した。円の半径やエッジの形状は、使用場所や取り付けする除雪装置により決定する。
以上の構造よりなる、円滑移動除雪エッジである。The problem was solved by forming the tip edge (1) of the snow removal device (2) such as a blade or bucket of a mechanical snow remover into a shape having an arc on the rear side toward the ground. The radius of the circle and the shape of the edge are determined by the place of use and the snow removal device to be attached.
This is a smooth moving snow removal edge having the above structure.

本発明の円滑移動除雪エッジは、このような構造であるから下記の効果が得られる。
（イ）円滑移動除雪エッジは常に除雪面の頂部に接触して、除雪面との間の雪のかき残しを最小にできる。
（ロ）円滑移動除雪エッジは、常に除雪面の頂部に接触していながら、段差や構造物を自由に乗り越え、構造物および除雪装置を損傷する可能性を大幅に減少できる。
（ハ）除雪装置のエッジを後方に向かって蒲鉾形に成形することにより、エッジと除雪面が面で接触でき、摩耗に耐え得ると共に、除雪装置の重量を分散して除雪面の損傷を防止できる。
（ニ）除雪装置のエッジを後方に向かって円形に成形することにより、除雪面と除雪装置のなす角度にかかわらず、エッジが段差や構造物に突き当たりにくくなる。
（ホ）本発明を応用することにより、除雪以外の作業においても、地面に対するバケットの微妙な高さ調整作業を軽減できる。
（ヘ）本発明は、除雪装置のエッジが後方に向かって円形となるため、除雪する雪に乗り上げてしまうように推測されがちであるが、実験で除雪能力を確認済みである。Since the smooth snow removal edge of the present invention has such a structure, the following effects can be obtained.
(B) The smooth-moving snow removal edge always contacts the top of the snow removal surface, and the amount of snow remaining between the snow removal surface can be minimized.
(B) While the smooth moving snow removal edge is always in contact with the top of the snow removal surface, it is possible to freely climb over steps and structures and greatly reduce the possibility of damaging the structure and the snow removal device.
(C) By forming the edge of the snow removal device in the shape of a bowl toward the rear, the edge and the snow removal surface can contact each other and withstand wear, and the weight of the snow removal device is dispersed to prevent damage to the snow removal surface. it can.
(D) By forming the edge of the snow removal device in a circular shape toward the rear, the edge does not easily hit a step or a structure regardless of the angle formed by the snow removal surface and the snow removal device.
(E) By applying the present invention, it is possible to reduce the delicate height adjustment work of the bucket relative to the ground even in work other than snow removal.
(F) In the present invention, since the edge of the snow removal device is circular toward the rear, it tends to be estimated that the snow removal device rides on the snow to be removed, but the snow removal capability has been confirmed by experiments.

以下、本発明の実施例について説明する。
機械式除雪機のブレードやバケット等除雪装置（２）のエッジ（１）を、地面に向かって後方に円弧を有する形に成形する。エッジの先端も、除雪機の後退を考慮して円弧を有する形状に仕上げる。円の半径やエッジの形状は、使用場所や取り付けする除雪装置により決定する。
本発明は、以上のような構造で、これを使用する時は、除雪面の凹凸を自由に乗り越えながら除雪作業が可能となる。Examples of the present invention will be described below.
The edge (1) of the snow removal device (2) such as a blade or bucket of a mechanical snow remover is formed into a shape having an arc on the rear side toward the ground. The tip of the edge is also finished in a shape having an arc in consideration of the retreat of the snowplow. The radius of the circle and the shape of the edge are determined by the place of use and the snow removal device to be attached.
The present invention has a structure as described above. When this is used, snow removal work can be performed while freely overcoming the unevenness of the snow removal surface.
