Here, even when the discharge door 141 of the discharge unit 140 is opened, the stirring unit 130 continues to rotate and stir and rotate the mortar 5.

The mortar 5 stored in the stirring space 121 is discharged through the discharging part 140 by its own weight but the amount of the mortar 5 in the stirring space 121 is not large, Even if the amount of the remaining mortar 5 is small at the position where the discharge hole 121a and the discharge portion 140 are formed and the discharge is not performed due to the self weight, the mortar 5 is discharged by the stirring portion 130, The discharge portion 121a and the discharge portion 140 to increase the discharge efficiency, thereby improving the convenience of the operator.

The mortar 5 discharged as described above is installed in the grating coupling portion 22 of the grating pedestal 20 after the worker places the mortar 5 stored in the barrel b on the road side wall 2, The work can be completed by combining the grating 10 with the grating 10.

A mortar injection hose 170 capable of being coupled to the discharge hopper 142 of the discharge unit 140 may be formed so that the discharge door 141 of the discharge unit 140 is opened, And the agitated mortar 5 is placed in the reactor 2 to further improve the workability.

Particularly, since the mixer apparatus 100 of the present invention can be easily moved with a simple structure as described above, the mixer apparatus 100 can be very usefully used when a small amount of mortar 5 is laid.

On the other hand, the mixer device 100 as described above is moved using a truck T having a built-in hydrate storage box.

As shown in FIG. 17, the mixer apparatus 100 of the present invention is provided with the auxiliary wheels 180, so that the mixer apparatus 100 is loaded on the baggage loading box. This process is very convenient and it also helps to improve the convenience of the operator.
