（ａ）産業上の利用分野
本発明は除雪プラウ、特にプラウを前後揺動可能にした
除雪プラウであって、プラウに異常な外力が作用した際
プラウを外力から回避させるようにした安全装置の分野
で利用されるものである。Detailed Description of the Invention (a) Industrial Application Field The present invention relates to a snow removal plow, particularly a snow removal plow that allows the plow to swing back and forth, so that when an abnormal external force is applied to the plow, the plow can avoid the external force. It is used in the field of safety devices designed to

回避するようになっている。(b) Prior Art A conventional safety device, as disclosed in Japanese Utility Model Application No. 55-36295@, consists of continuously installing end plows on the side of the plow body, and connecting the end plows to the plow through an arm. It is pivotally supported on the main body, and a shearing pin is installed between the bracket on the plow main body side and the arm, and when an abnormal external force is applied to the end plow, the shearing pin is cut and the end plow rotates backward to avoid the external force. It looks like this.
（Ｃ）発明が解決しようとする課題
ところが前記構造であれば、プラウを可変（前後揺動可
能）にするためにはプラウにシリンダを設ける必要があ

用してもシリンダが端部プラウを固定した状態になって
いるためシャーピンが役立たず、端部プラウを破損させ
る危険がある。(C) Problem to be Solved by the Invention If the structure is as described above, it is necessary to provide a cylinder to the plow in order to make the plow variable (possible to swing back and forth), but if a cylinder is provided to the end plow, it will cause an abnormality. Even if a strong external force is applied, the cylinder remains fixed to the end plow, so the shear pin is useless and there is a risk of damaging the end plow.

常な外力から回避できるが、通常の除雪作業の繰り返し
にてアームが変形しプラウ本体と端部プラウとの接続面
が離れて除雪作業が充分に行なえなくなるという問題が
ある。In addition, if a cylinder is installed in the plow body, the end plow can be protected from abnormal external forces, but the arm deforms due to repeated normal snow removal work, and the connection surface between the plow body and the end plow separates, making it difficult to remove snow. The problem is that they are not able to do it enough.

とにある。Therefore, the purpose of this invention is to provide a cylinder on the rear side of the plow via a swinging arm, and further provide a shear pin between the plow side and the swinging arm, so that the plow can be swinged by the cylinder during normal use, and To provide a safety device for a variable snow removal plow which prevents damage to the plow by cutting a shear pin when an abnormal external force acts on the plow.

たことを特徴とするものである。(d) Means for Solving the Problems The present invention provides a variable snow removal plow in which the plow is supported by an attachment member to a vehicle and can be swung back and forth by a cylinder provided on the attachment member. A swinging arm capable of swinging from side to side is pivotally supported, a tip of the cylinder is pivotally supported on a part of the swinging arm, and a bracket is provided on the rear side of the plow, and the bracket and the swinging arm are connected to each other. The plow is characterized in that a shear pin is provided between the plow and the plow to restrict the rotation of the swing arm and to release the restriction when an abnormal external force is applied to the plow.
（ｅ）作用
゛除雪作業時にはまずシリンダにてプラウを任意の角度
に揺動させてセットする。(e) Operation: During snow removal work, first set the plow by swinging it to an arbitrary angle using the cylinder.
その際揺動アームはシャーピンにて固定されているため
シリンダの伸縮にてプラウを揺動させることができる。At this time, since the swing arm is fixed with a shear pin, the plow can be swinged by expanding and contracting the cylinder.
その状態で走行することによりプラウが雪を導いて除雪
を行なう。By driving in this state, the plow guides the snow and removes it.
作業中にプラウに異常な外力、例えば歩道の段差部や歩
道との境を示すポールなどに当ることにより発生する外
力が作用すると、シャーピンが切断され、揺動アームの
規制が解除されるため、シリンダはそのま・でプラウが
後方に回動し、プラウの破損を防止する。If an abnormal external force is applied to the plow during work, such as when it hits a step on the sidewalk or a pole that marks the boundary between the plow and the sidewalk, the shear pin will break and the swing arm will be released. With the cylinder left in place, the plow rotates backwards, preventing damage to the plow.
