なお、攪拌バーは図示したものに限らず、ミキシングパドルの先端部にブレードを 取付けたもの等、セメントや砂等のドライミックスコンクリートと水を攪拌することができ るものであれば、どんな構造のものであってもよい。  The stirring bar is not limited to the one shown in the figure, but any structure can be used as long as it can stir dry mix concrete such as cement or sand and water, such as a blade attached to the tip of the mixing paddle. It may be a thing.

[0020] 上記構成のコンクリートミキサー車 1は、生コンクリートの使用量が少ない場合には、 該コンクリートミキサー車 1の荷台 3に工場で計量され、ノック D詰めされたコンクリー ト骨材 Eを積載するとともに、現場での水の確保ができない場合には、水タンク 35〖こ 水を収納して建設現場 Bへ運転して運び、生コンクリートの使用量の多い場合にはコ ンクリートミキサー車 1だけ運転して運び、建設現場 Bでほぼ水平状態に位置された コンクリートミキサードラム 10、 10内に、投入口 9、 9より生コンクリート材料の輸送ェ 程 Hあるいはコンクリートミキサー車搬入工程 Iで建設現場 Bへ搬入されたコンクリート 骨材 E、 Eと計量した水を水タンク 35より入れ、攪拌装置 16、 16の油圧モーター 30、 30を駆動させて回転軸 27、 27および攪拌バー 28、 28を回転させて生コンクリートを 製造する。 [0020] When the amount of the ready-mixed concrete is small, the concrete mixer truck 1 having the above configuration is loaded with the concrete aggregate E packed in the knock D in the weighing platform 3 of the concrete mixer truck 1 at the factory. At the same time, if water cannot be secured on site, it can be stored and transported to construction site B by storing 35 tons of water tank. Neckreet mixer truck 1 is transported and transported to concrete mixer drums 10 and 10 located almost horizontally at construction site B. Concrete aggregate carried into construction site B by I Put water weighed with aggregates E and E from water tank 35, drive hydraulic motors 30 and 30 of stirrers 16 and 16, and rotate rotary shafts 27 and 27 and stir bar 28 , Rotate 28 to produce ready-mixed concrete.

生コンクリートが製造されると、回動機構 14、 14の油圧シリンダー 13、 13を駆動さ せて、コンクリートミキサードラム 10、 10の排出口 8、 8を下方に位置するように他端部 側を上方へ回動させ、開閉扉 15、 15の開閉扉用油圧シリンダー 24、 24、 24、 24を 作動させて開閉扉本体 21、 21を開放することにより、コンクリートミキサードラム 10、 1 0内の生コンクリートは排出口 8、 8よりシユータ 17内へ落下させて、該シユータ 17より コンクリートポンプ車のホッパーやトレーへ排出させることができる。  When ready-mixed concrete is manufactured, the hydraulic cylinders 13 and 13 of the rotating mechanisms 14 and 14 are driven, and the other end side is moved so that the discharge ports 8 and 8 of the concrete mixer drums 10 and 10 are positioned downward. By rotating upward and operating the hydraulic cylinders 24, 24, 24, 24 for the open / close doors 15 and 15, and opening the open / close door bodies 21 and 21, the raw material in the concrete mixer drums 10 and 10 is generated. Concrete can be dropped into the shouter 17 from the discharge ports 8 and 8, and can be discharged from the scouter 17 to the hopper or tray of the concrete pump truck.

なお、コンクリートミキサードラム 10、 10はベース体 6に 2個設けられているので、時 間をずらせて生コンクリートを製造することにより、順次効率よく生コンクリートを製造 することができる。  Since two concrete mixer drums 10 and 10 are provided on the base body 6, ready-mixed concrete can be manufactured sequentially and efficiently by shifting the time and manufacturing ready-mixed concrete.

[0021] 上記のように構成された生コンクリートの打設方法 Aは、建設現場 Bで水とコンクリー ト骨材 Eとをコンクリートミキサー車 1のコンクリートミキサードラム 10、 10で攪拌して生 コンクリートを製造するので、生コンクリートが出来上がって力 打設するまでに長時 間力かったりすることなぐ生コンクリートの品質が低下することなく使用できるとともに 、ミキサー車のように運送距離や運送時間、交通渋滞等による悪影響を確実に防止 することができる。  [0021] The method of placing ready-mixed concrete A configured as described above involves mixing raw water and concrete aggregate E with concrete mixer drums 10 and 10 of a concrete mixer truck 1 at a construction site B to prepare ready-mixed concrete. Since it is manufactured, it can be used without degrading the quality of the ready-mixed concrete, which does not require a long time before the ready-mixed concrete is put into place, and it can be used for transport distance, transport time and traffic congestion like a mixer truck. It is possible to reliably prevent adverse effects caused by such factors.
