Abstract

PROBLEM TO BE SOLVED: To prevent waste water from draining and to contribute to pollution prevention by freely changing the position of a vessel receiving waste water at washing a chuter to a waste water receiving position under the discharge port of the chuter and to the shunting position. SOLUTION: When a chuter 2 is washed after flowing concrete in a jobfield, this device fixed on a shunting position with a lock pin 7 unlocked, a vessel 5 is horizontally rotationally moved while setting the receiving base on the extreme end of an arm 13 as a fulcrum 20, it is positioned under the discharge port of the chuter 2, and sewage water 3 mixed with concrete stuck to the chuter is let flow in the vessel 5 by washing water. At completing the work, the vessel 5 is covered with a cover 6 and fixed, next the lock pin 7 is unlocked, and it is fixed on the shunting position except the sewage water receiving position with the lock pin 7. Thereafter a concrete mixer truck is moved, and the vessel 5 is taken out at a designated place by a concrete trader so as to throw away the waste water mixed with concrete.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a sewage treatment apparatus generated when washing a shooter of a concrete mixer truck.

[0002]

2. Description of the Related Art Conventionally, an apparatus for storing and treating sewage generated during washing of a shooter of a concrete mixer truck has not been prepared near a shooter, and sewage generated during washing has often flowed down onto a road surface as it is.

[0003]

Therefore, the drained sewage flows into roads and drains in rainy weather and the like, causing pollution.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a concrete mixer truck having a shooter for discharging and guiding concrete, provided with a container for receiving sewage mixed with concrete when the shooter is washed. The container is configured such that the position of the container can be freely changed between a sewage receiving position located below the discharge port of the shooter and a retracted position other than the sewage receiving position.

[0005]

After the on-site work of the concrete mixer truck 1, when the wastewater 3 mixed with concrete remaining in the shooter 2 is washed away, the container 5 housed between the rear wheel 4 and the shooter 2 is rotated and the shooter is rotated. 2, the wastewater is poured into the container 5 with the washing water normally provided in the concrete mixer truck 1, and after the work is completed, the lid 6 is covered and fixed to the container 5, the lock pin 7 is released, and the wastewater is collected. The concrete mixer truck 1 is moved to the evacuation position other than the position and locked, and then the concrete mixer truck 1 is moved to take out the container 5 to a place designated by the concrete contractor and to drain the concrete.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. 1 is a concrete mixer truck, 2
Is a shooter and 5 is a container. The concrete is put into the drum 9 from the hopper 8, transported to a designated place at the required site, and the concrete is taken from the drum 9 to the shooter 2.
Start pouring work via.

[0007] When the above operation is completed, it is necessary to wash out the sewage 3 mixed with concrete before it adheres to the shooter 2 and hardens. Therefore, a container 5 provided in the concrete car 1 for receiving sewage is positioned below the discharge port of the shooter 2, and sewage mixed with concrete is poured into the container 5 by washing.

[0008] Then, the adhesion of sewage mixed with concrete to the shooter 2 is substantially eliminated, and after the work is completed, the lid 6 is placed in the container 5.
, And the lock pin 7 is released, and the lock pin 7 is fixed at a retracted position other than the sewage receiving position. Lock pin 7
May be a one-touch operation using the spring 18 or the like as shown in FIG. Explaining the structure of other parts, the plate 1 and the boss 12 are fixed to the bumper 10 and at the same time, the arm 1 that rotates around the boss 12
The arm 13 has a plate A 14 and a container holder 15 fixed thereto. The plate 11 and the plate A14 are provided with lock holes having a suitable radius at the same position with the boss 12 as a center. The lock pin 7 is released or locked to position the container 5 below the discharge port of the shooter 2 or to store the container 5 at the retracted position. The 16 container fixing hooks are provided at several places so as to fix the container 5 with one touch.

The container 5 has been described as being configured to rotate horizontally to the cradle at the tip of the arm 13 in order to change between the receiving operation position and the retracted storage position, but as shown in FIG. The path may be changed so as to reciprocate.

Next, the operation of the present invention will be described. In the above-described concrete mixer truck 1, when the shooter 2 is washed after the concrete is poured at the work site,
The device fixed to the retracted position with the lock pin 7 (corresponding to the lock pin 17 in FIG. 5) is released, the container 5 is positioned below the discharge port of the shooter 2, and the concrete adhering to the shooter is washed with water. Is poured into the container 5. When the above operation is completed, cover 6 is fixed to container 5,
Next, the lock pin 7 is released and fixed to the retracted position other than the sewage receiving position with the lock pin 7, and then the concrete mixer truck 1 is moved, and the container 5 is taken out to a place specified by the concrete contractor, and the concrete mixed sewage is drained.

[0011]

As described above, according to the present invention, after the work is completed at the work site requiring the concrete mixer truck 1,
In particular, concrete-contaminated sewage adhering to the shooter 2 hardens quickly because it is in direct contact with the outside air, and adheres to the shooter 2. For this reason, it is not an exaggeration to say that it is the shooter 2 that performs the cleaning first after the work is completed. According to the present invention, when cleaning the shooter 2, the container 5 can be easily positioned below the discharge port of the shooter 2, the sewage mixed with concrete can be immediately poured, and the sewage mixed with concrete does not solidify in the shooter 2. In addition, since there is no trouble as in the related art, there is no drip on a road surface or the like, which contributes to prevention of pollution.
