課題を解決するための手段  Means for solving the problem
[0006] 上記目的を達成するために、本発明はベース体と、このベース体に設けられた支 持台と、この支持台に下部に排出口を有する一端部を回動可能に枢支された上部 に投入口を設けたほぼ円筒状のコンクリートミキサードラムと、このコンクリートミキサ 一ドラムの排出口を下方へ位置できるように、該コンクリートミキサードラムを回動させ る回動機構と、前記コンクリートミキサードラムの排出口を開閉する開閉扉と、前記コ ンクリートミキサードラムに設けられた攪拌装置とでコンクリートミキサーを構成してい る。 [0006] In order to achieve the above object, the present invention is pivotally supported by a base body, a support base provided on the base body, and an end portion having a discharge port at a lower portion of the support base. The concrete mixer drum is rotated so that the substantially cylindrical concrete mixer drum provided with an inlet at the top and the outlet of this concrete mixer can be positioned downward. A concrete mixer is constituted by a rotating mechanism that opens and closes, an opening / closing door that opens and closes the discharge port of the concrete mixer drum, and a stirring device provided in the concrete mixer drum.
発明の効果  The invention's effect
[0007] 以下の説明から明らかなように、本発明にあっては次に列挙する効果が得られる。  As will be apparent from the following description, the present invention provides the following effects.
[0008] (1)ベース体と、このベース体に設けられた支持台と、この支持台に下部に排出口を 有する一端部を回動可能に枢支された上部に投入口を設けたほぼ円筒状のコンクリ ートミキサードラムと、このコンクリートミキサードラムの排出口を下方へ位置できるよう に、該コンクリートミキサードラムを回動させる回動機構と、前記コンクリートミキサード ラムの排出口を開閉する開閉扉と、前記コンクリートミキサードラムに設けられた攪拌 装置とで構成されているので、回動機構によってコンクリートミキサードラムを回動さ せることにより、排出口を下部に位置させることができる。 [0008] (1) A base body, a support base provided on the base body, and one end having a discharge port in the lower part of the support base, and an input port provided in an upper part pivotally supported by the upper part. Cylindrical concrete mixer drum, rotation mechanism for rotating the concrete mixer drum so that the outlet of the concrete mixer drum can be positioned downward, and opening / closing to open and close the outlet of the concrete mixer drum Since it is comprised with the door and the stirring apparatus provided in the said concrete mixer drum, a discharge port can be located in the lower part by rotating a concrete mixer drum by a rotation mechanism.
したがって、コンクリートミキサードラム内のコンクリートを効率よく外部へ排出するこ とがでさる。  Therefore, the concrete in the concrete mixer drum can be efficiently discharged to the outside.
[0009] (2)前記（1)によって、コンクリートを外部へ排出する場合にだけコンクリートミキサー ドラムを回動させて、他端部を上方へ位置させるため、攪拌時にはコンクリートミキサ 一ドラムが高い位置にならないので、安定した状態で攪拌作業を行なうことができる。  (2) According to the above (1), the concrete mixer drum is rotated only when the concrete is discharged to the outside, and the other end is positioned upward. Therefore, the stirring operation can be performed in a stable state.
[0010] (3)前記（1)によって、ほぼ円筒状のコンクリートミキサードラムを用いるので、該コン クリートミキサードラムを約 30〜40度程、回動機構で回動させるだけで効率よくコンク リートを外部へ排出することができる。  [0010] (3) Since the substantially cylindrical concrete mixer drum is used according to the above (1), the concrete can be efficiently removed simply by rotating the concrete mixer drum by about 30 to 40 degrees with a rotating mechanism. It can be discharged to the outside.
[0011] (4)前記（1)によって、ベース体を地面あるいはトラックの荷台に容易に設置すること ができる。  [0011] (4) According to the above (1), the base body can be easily installed on the ground or a truck bed.
したがって、どんな所でも使用することができる。  Therefore, it can be used anywhere.
[0012] (5)前記（1)によって、コンクリートミキサードラムを高い位置に設置しなくてもよいの で、コンクリートミキサードラム内へのコンクリート原料の投入作業を容易に行なうこと ができる。 [0012] (5) According to the above (1), the concrete mixer drum does not have to be installed at a high position, and therefore, the operation of putting the concrete raw material into the concrete mixer drum can be easily performed.
[0013] (6)請求項 2、 3も前記（1)〜（5)と同様な効果が得られるとともに、少なくとも 2個のコ ンクリートミキサードラムで順次効率よくコンクリートを製造することができるとともに、車 両によって効率よく使用現場へ持ち込むことができる。 [0013] (6) In claims 2 and 3, the same effects as in the above (1) to (5) can be obtained, and concrete can be produced sequentially and efficiently with at least two concrete mixer drums. car Both can be brought to the site of use efficiently.
