【発明の詳細な説明】 〔産業上の利用分野〕 本発明は散布車によって路面上に凍結防止剤を散布する
場合において、ホッパー内の凍結防止剤の残量を自動的
に検出する方法に関するものである。TECHNICAL FIELD The present invention relates to a method for automatically detecting the remaining amount of the antifreezing agent in a hopper when the antifreezing agent is sprayed on the road surface by a spraying vehicle. Is.
従来から、冬季における走行中の自動車のスリップ事故
や交通渋滞等の道路障害を防止するために、散布車によ
って路面に凍結防止剤を散布することが行われている。BACKGROUND ART Conventionally, in order to prevent road accidents such as slip accidents and traffic jams of a running vehicle in winter, a spray vehicle sprays an antifreezing agent on the road surface.
この場合、散布車に設置したホッパー内に一定量の凍結
防止剤を投入し、該ホッパーの下方に配設したコンベア

円滑に行う必要がある。In this case, a certain amount of antifreeze agent is put into the hopper installed in the spray truck, and it is carried out by the conveyor arranged below the hopper and sprayed on the road surface, but it decreases depending on the spray amount. It is necessary to confirm the remaining amount of the antifreezing agent in the hopper, eliminate the road surface on which spraying is not performed, enable continuous spraying over the entire length of the road surface, and smoothly supply the next antifreezing agent.

で、残量が僅かであるにも拘わらず未だ充分な量が残っ
ているとの誤認が行われることになり、正確な残量の確
認が困難であるという問題点があった。However, in any of the above methods, as the surface of the antifreezing agent in the hopper decreases, if it always descends in a horizontal state like the water surface in the water tank, the remaining amount can be confirmed almost accurately. In the case of a powdered antifreezing agent, the surface of the hopper is inclined downward as it goes rearward due to the inner wall of the hopper inclined toward the lower end opening. There is a problem in that it is difficult to accurately confirm the remaining amount because it is erroneously recognized that the remaining amount remains.
本発明はこのような問題点を解消し得る凍結防止剤の散

凍結防止剤（ａ）の比重とによりベルトコンベア（３）
間を通過する凍結防止剤（ａ）の重量を演算させる。After setting in this way, the spray car is operated and the antifreeze agent (a) in the hopper (2) is conveyed backward by the belt conveyor (3) and dropped onto the chute (11) via the gate (4). Then, the spray disc (13) is used to spray on the road surface. At that time, the opening of the gate (4) and the speed of the belt conveyor (3) are adjusted by the potentiometer (10) and the tacho-generator (8). The belt conveyor (3) is made to detect each of them, and inputs the output to the computer (14) to detect the gate width and the specific gravity of the antifreezing agent (a).
The weight of the antifreezing agent (a) passing through the space is calculated.
この演算は、次式によって求めることができる。This calculation can be obtained by the following equation.
Qkg/s＝Hm×Lm×γg/cm3×Vm/s×103 但し、Qkg :1秒当たりの排出量 Hm ：ゲートの開度 Lm ：ゲート幅 γg/cm3 ：凍結防止剤の比重 Vm/s ：ベルトコンベアの速度 なお、上式には必要に応じて適宜な補正定数を付加する
こともできる。Qkg / s = Hm × Lm × γg / cm 3 × Vm / s × 10 3 However, Qkg: Emission amount per second Hm: Gate opening Lm: Gate width γg / cm 3 : Specific gravity of antifreezing agent Vm / s: Belt conveyor speed In addition, an appropriate correction constant can be added to the above equation as necessary.
又、上記式において、γ＝１とすれば、容量表示にする
ことができる。Further, if γ = 1 in the above equation, it is possible to display the capacity.
この演算を例えば0.5秒間隔毎に行ってその重量を前記
ホッパー（２）内に投入した重量から減算し、その数値
