Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a washing sewage storage device for a concrete mixer truck, and more particularly, to a washing sewage storage device for a concrete mixer truck.

After discharging ready-mixed concrete (see below), when cleaning the ready-mixed concrete adhering to the discharge chute at the discharge work site, the washed wastewater can be temporarily stored and transported to a designated disposal site or treatment plant before being disposed of. This invention relates to a washing sewage storage device for a concrete mixer truck. This is used in the field of preventing environmental pollution caused by washing sewage from concrete mixer trucks.

(b) Prior Art In a concrete mixer truck 1 as shown in FIG. After the ready-mixed concrete in the drum 2 is discharged from the discharge chute 3, the ready-mixed concrete adhering to the i' crumb, the hopper 4, and the inside of the chute 3 is generally washed with water or the like at the work site.

Among the cleaning wastewater generated at this time, the wastewater that washes the drum is inevitably stored in the drum, so there is almost no dripping, but the lG water that washes the hopper and chute is often flushed away as is at the work site. Since it causes environmental pollution, countermeasures are being taken. As an example of points 2 and 3, although not shown, a sewage storage tank is removably provided on the vehicle body, the cleaning sewage from the discharge chute is guided and stored using a hose, and after being transported to a disposal site, the tank is attached to the vehicle body. (Special Publication Publication No. 57-40315), or by suspending a tank from the lower end of the discharge chute and pouring the washed wastewater directly into it, storing it in the car body, and then opening the bottom of the tank at an IT site and disposing of it. (Jikko Sho 58-498).

However, the weight of the tank in which washed wastewater is stored is 20 kg.
In the former case, when disposing of the tank, and in the latter case, when storing the tank, workers must raise and lower the tank, which not only becomes hard work, but also wastes water from cleaning. The disadvantage is that it requires time and effort to store and dispose of.

(C) Purpose of the Invention The present invention has been made to solve the above-mentioned drawbacks.
To provide a washing sewage storage device for a concrete mixer truck which allows storage and disposal of washing sewage extremely easily and reliably, and eliminates heavy labor in the work.

(d) Structure of the Invention The structure of the present invention will be explained with reference to FIG. A sewage storage tank 11 that can be horizontally rotated via a freely provided rotary arm 14 and vertically rotatable about the rotary arm 14.
This is a washing sewage storage device for a concrete mixer truck, in which the tank 11 is equipped with a locking body 22, 27 for preventing rotation and rotation of the tank 11.

According to this, when the sewage storage tank 11 is horizontally rotated with its rotation prevented, it can accommodate the washed sewage from the discharge outlet 3, and the rotation is not blocked or prevented. When vertically rotated in this state, the washed wastewater can be disposed of from the wastewater storage container 11.

(e) Examples Hereinafter, the present invention will be explained in detail based on examples thereof.

As shown in FIG. 1, the sewage storage tank 11 of the washed sewage storage device 10 is installed at the rear of the concrete mixer truck 1 and below the discharge shoes 1 to 3 so as to be able to rotate horizontally and vertically. There is. In the detailed views of FIGS. 2(a) and 2(b), reference numeral 12 denotes a shaft body, which is erected and fixed to a part of the chassis frame 13 below the discharge chute 3, as shown in FIG. This swing arm is fixed to a hollow shaft 15 fitted into the shaft body 12 via a member 14a and is horizontally swingable. Reference numeral 16 denotes a hollow shaft that penetrates through the interior of the wastewater storage tank 11 and is fixed thereto. A swing arm 14 is inserted through the hollow shaft 16, and the wastewater storage tank 11 is mounted so as to be vertically rotatable around the swing arm 14. ing. In addition,
Reference numeral 17 denotes a stopper, and the rotating arm 14 is attached to the hollow shaft 1.
By inserting a pin (not shown) into a pin hole 18 bored into the end of the sewage storage tank 11 and the swiveling arm 14, the sewage storage tank 11 and the swiveling arm 14 are are integrated. Reference numeral 19 denotes a lid of the sewage storage tank 11, which has a handle 20 attached to its upper surface and is rotatably mounted around a shaft 21 that penetrates the inside of the sewage storage tank 11 and is fixed. Note that the shape of the lη water storage tank 11 is not limited to the box shape shown in the figure, but it is preferable that the upper opening be relatively large in order to facilitate the reception of cleaning wastewater from the discharge shoe 1-3.

Reference numeral 22 denotes a securing body that prevents horizontal rotation of the wastewater storage tank 11, and as shown in FIG. 4, a horizontal U-shaped bracket 23 into which the tip of the rotation arm 14 is fitted is fixed to a part of the chassis frame. At the same time, pin 2 is attached to the bracket 1-23.
A pin hole Z5 for inserting the pin 4 is bored. Note that the pin 24 is held on the vehicle body via a chain 26 to prevent it from falling off. This horizontal turning fixation allows the wastewater storage tank 11 to be prevented from turning while the vehicle is running. If the sewage storage tank 11 is rectangular, a removable rod or plate is placed on a part of the chassis frame so as to be in contact with the front or side of the sewage storage tank 11, and a sewage storage hook is installed. 11 may be prevented from turning. 27 is a lashing body that prevents vertical rotation of the sewage storage hook 11 around the rotation arm 14;
As shown in the figure, a bracket 28 is fixed to the side surface 11d of the sewage storage tank 11, and a bracket 29 is fixed to the hollow shaft 15, and a pin 30 is inserted into each bottle hole 31 and 32, and the sewage water is Regardless of whether or not the storage tank 11 rotates, vertical rotation of the sewage storage hook 11 can be enabled or prevented. Note that the pin 30 is held on the vehicle body via a chain 33. This ensures that the sewage storage tank 11 is secured when the vehicle is stopped.
As long as it is released so that it can be rotated vertically, the structure is limited to the above-mentioned configuration, and other known lashing bodies using hooks or the like may be used, which is similar to the aforementioned lashing body 22. .

According to one embodiment of the configuration described above, cleaning wastewater can be stored, transported, and disposed of in the following manner.

When the concrete mixer trucks 1 to 1 arrive at the work site and discharge the ready-mixed concrete in the drum 2, the discharge sheet 3 is moved by a cylinder (not shown) or the like to the solid line or dashed line in FIG. 2(a) or to the paper surface. The fresh concrete is turned at right angles and discharged in the desired direction. When the discharge is completed, the ready-mixed concrete attached to the hopper and the discharge chute 1-3 is washed away by running water from the hopper or by spraying water on the discharge chute 3 with a hose, before it hardens. Ru. At that time, the operator first pulls out the pin 24 of the lashing body 22 from the bracket 23 to release the lashing of the swing arm 14. Therefore, the sewage storage tank 11 is manually horizontally rotated approximately 90 degrees about the shaft body 12 in the direction of arrow 34 from the position shown by the solid line in FIG. 2(b) to the position shown by the two-dot chain line. At this time, vertical rotation of the sewage storage tank 11 around the swing arm 14 by the lashing body 27 is maintained in a blocked state. next,
The operator turns the handle 20 shown in FIG. 2(C) in the direction of the arrow mark 35 to rotate the lid 19 around the shaft 21.
Open as shown by the two-dot chain line in a). Therefore, the operator moves the discharge chute 3 from the one-dot chain line position to the open sewage storage tank 11 at the two-dot chain line position using a rotating mechanism such as a cylinder (not shown) and a vertical movement mechanism, and then moves the discharge chute 3 to the hopper and the discharge chute. Wash 3. The washed wastewater is guided by the lid 19 and stored in the wastewater storage tank 11 while being prevented from spilling. When the washing is completed and the washed wastewater is stored in the wastewater storage tank 11, the discharge chute 3 is retracted, the lid 19 is manually closed, and the lid 19 is closed manually, and the drain chute 3 is retracted and the lid 19 is closed manually.
Turn horizontally in the opposite direction of step 4 and store a part of the vehicle body in its original position. After storing, the pin 24 of the securing body 22 shown in FIG.
is inserted into the pin hole 25 to prevent the horizontal rotation of the wastewater storage tank 11, allowing the vehicle to run. At this time,
The prevention of vertical rotation by the lashing body 27 is also maintained,
Concrete mixer trucks transport washed wastewater from the work site to a disposal site or treatment plant. At the disposal site, a worker attaches the pin 30 of the lashing body 27 shown in FIG. 5 to the bracket 28.2.
9, the wastewater storage tank 11 is removed from the rotating arm 1.
It can be rotated around 4. In addition, sewage storage tank 11
2 (C
), and the lid 19 is opened with this rotation or manually, and the washed wastewater is disposed of from the wastewater storage tank 11. Sewage storage tank 1 during disposal work
If it is more convenient to rotate the sewage storage tank 11, the sewage storage tank 11 may be rotated in the same manner as in the case of storing washed sewage as described above, and then the restraint on vertical rotation by the lashing body 27 may be released. .

In these operations, pins 24 and 30 of each lashing body
are held to the vehicle body via chains 26 and 33, respectively, so they can be simply removed without being lost. When the disposal of washed wastewater is completed, the wastewater storage tank 11 is rotated to its original state, its vertical rotation is prevented by the securing body 27, and the lid 19 is closed. If necessary, the tank is rotated horizontally and the empty wastewater is removed. The storage tank 11 is shown in Fig. 1, Fig. 2 (a), and (b).
It is possible to return it to the initial position shown by the solid line and store it in the vehicle body, and to prevent horizontal turning by the lashing body 22, allowing the vehicle to run. It goes without saying that almost the same procedure is used when a different securing body than the one described above is employed to prevent horizontal rotation and vertical rotation.

(f) Effects of the Invention As explained in detail in the above embodiments, the present invention enables the sewage storage tank to be rotated horizontally and vertically. can be carried out easily and smoothly without heavy labor. Furthermore, since the sewage tank is provided with a securing body that prevents horizontal and vertical rotations of the sewage tank as necessary, the attitude of the sewage tank can be maintained and the tank can be safely stored in the vehicle body.

Therefore, there is no need to spill washing wastewater onto work sites or roads, even if the amount of washing wastewater is large.
Simply increasing the capacity of the sewage storage tank can avoid increasing the burden on workers and causing environmental pollution due to sewage that cannot be stored.
