【発明の詳細な説明】
本発明はミキサードラム内に付着した生コンクリートを
容易に清掃できるようにしたミキサー車に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mixer truck in which ready-mixed concrete adhering to the inside of the mixer drum can be easily cleaned.
一般にミキサー車はミキサードラムと螺旋状のブレード
と円筒形のシュートとにてドラム後部に螺旋状の搬出路
が形成され、この搬出路を通って生コンクリートが排出
されるようになっている。Generally, a mixer truck has a mixer drum, a spiral blade, and a cylindrical chute to form a spiral discharge path at the rear of the drum, through which fresh concrete is discharged.
ところが前記搬出路が螺旋状に形成されていることから
、搬出路壁面に付着した生コンクリートの清掃が非常に
困難で、ほとんどが清掃されずに放置されていた。その
ため、搬出路内に固結したコンクリートが堆積していき
、搬出路を狭くして生コンクリートの排出効率を悪くし
ていた。However, since the delivery path is formed in a spiral shape, it is very difficult to clean the fresh concrete adhering to the walls of the delivery path, and most of the fresh concrete is left uncleaned. As a result, hardened concrete accumulates within the delivery path, narrowing the delivery path and reducing the efficiency of discharging fresh concrete.
本発明は前記の如き欠点を無くすために搬出路内の清掃
を容易に行なえるようにしたものである。The present invention aims to eliminate the above-mentioned drawbacks by making it easier to clean the inside of the delivery path.

いる。Because the chute 5 is provided, the blade 4

It is now possible to wash the fresh concrete that has adhered to 4.
８は生コンクリートをシュート５側に導くホッパである

にて打設現場まで輸送する。The present invention has the above-mentioned structure, and its operation will be explained next. First, when transporting fresh concrete to a pouring site, the fresh concrete is passed from the hopper 8 through the chute 5 and stored in the drum 1, and the stored fresh concrete is The drum 1 is transported to the casting site while being rotated in the normal direction (solid arrow in Figure 2) to prevent it from hardening.
打設現場に着くとドラム１を逆転（第２図点線矢印）さ

ドラム１外に排出させる。When arriving at the pouring site, the drum 1 is reversed (as indicated by the dotted line arrow in Figure 2), and the ready-mixed concrete is discharged from the drum 1 through the delivery path 6 through the closing portion 3.
生コンクリートの排出が終了するとドラム１内には生コ

噴射させて洗浄する。When discharge of the fresh concrete is completed, since the fresh concrete is still attached to the inside of the drum 1, cleaning water is injected into the drum 1 to clean it.

な問題はまった〈なくなる。In particular, cleaning of the inside of the delivery path 6 is carried out by spraying cleaning water from the opening 3 through the holes 7 of the blades 4, 4 onto the outer surface of the chute 5 in the delivery path 6 and onto the blades 4, 4. This makes it easy to clean. As described above, in the present invention, since the blade, especially the part exposed from the drum entrance, is provided with multiple holes, cleaning water can be injected into the delivery path from outside the drum through these holes. It becomes very easy to clean the concrete, and the conventional problem of hardening of fresh concrete in the conveyance path, which impairs the discharge efficiency of the fresh concrete, is completely eliminated.
