キー場のスキー滑走雪面の整備を安全かつ、効率的、経
済的に行なわせるための考案に関するものである。Detailed Description of the Invention A. Purpose of device a. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to a maintenance machine for skiing, and relates to a device for safely, efficiently and economically maintaining a skiing snow surface of a skiing area.
ｂ．従来の技術とその問題点 従来のゲレンデ整備車は、幅広履帯式トラクターの後部
に装備したゲレンデ整備作業機１１（以下作業機と称す
る）は、左右方向に旋回できない構造で構成されてい
た。b. 2. Description of the Related Art In the conventional slope maintenance vehicle, a slope maintenance work machine 11 (hereinafter, referred to as a work machine) mounted on a rear portion of a wide crawler tractor has a structure in which it cannot turn in the left-right direction.
従って、次の如き問題があった。Therefore, there are the following problems.
イ．方向変換のため操向操作を行なって旋回走行する
と、第６図の如く旋回内側の履帯跡１９が残る。I. When a steering operation is performed to change the direction and the vehicle travels by turning, a track 19 on the inside of the turning remains as shown in FIG.
旋回で形成される履帯跡は、雪面を深くえぐり取り、ま
た、雪を押し上げるので、凹凸が激しく雪面が荒らされ
る。それは旋回内側半径Ｒが小さい程、荒れ方が大きく
なる傾向がある。薄暮、降雪、また吹雪のときなどでは
スキーヤーには前方に履帯跡１９を発見することは困難
でしばしばスキーを引っ掛け転倒することがあり、極め
て危険である。The track tracks that are formed by turning excavate the snow surface deeply and push up the snow, so the snow surface is rough and rough. The smaller the inner radius R of the turning, the greater the tendency for roughness. In dusk, snowfall, or snowstorm, it is difficult for the skier to find the track tracks 19 in front of him, and the ski is often caught and falls, which is extremely dangerous.
ロ．スキー場では緊急的、または臨時的にケガ人の輸
送、スキー大会用機材の輸送等々で滑走雪面を走行する
ことが多く、その都度履帯跡が残されている。B. At ski resorts, people often run on skis for urgent or temporary transportation of injured people, equipment for ski competitions, etc., and track tracks are left on each occasion.
ハ．狭隘なスキーコースでは方向変換する場所を特別に
設定しなければならず、そのため有効滑走面積が減少す
ることが余儀なくされている。C. In a narrow ski course, the place to change direction has to be set specially, which inevitably reduces the effective skiing area.
ニ．一時に多量の降雪があったときなどは、深雪の中の
トラクターの後方を、作業機１１が追随することにな
る。したがって、旋回走行するときは、作業機１１の外
側部２０は雪壁を外方向に押し付け、雪壁を崩しながら
の作業となり、仕上がりも悪く、作業機１１や接続金具
１２などにも過大な力が加わり、故障多発の原因にもな
っている。D. When there is a large amount of snowfall at one time, the working machine 11 follows the tractor behind deep snow. Therefore, when turning, the outer portion 20 of the working machine 11 pushes the snow wall outward, and the work is performed while collapsing the snow wall, resulting in poor finish and excessive force on the working machine 11 and the connecting fittings 12. Is added, which is also a cause of frequent failures.
スキー場はスポーツの中で障害発生率が最も高いと言わ
れている。したがって、滑走雪面に履帯跡を残さないゲ
レンデ整備車の開発は早くから強く望まれていた。Ski resorts are said to have the highest rate of disability in sports. Therefore, the development of a slope maintenance vehicle that does not leave track marks on the gliding snow surface has been strongly desired early on.
図中、Ｗ２は従来の作業機の仕上げ幅を示す。In the figure, W 2 indicates the finishing width of the conventional working machine.
