Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cleaning waste water storage box for a mixer vehicle, which is used as a waste water storage box for receiving and storing noro water flowing out from a chute in a concrete mixer vehicle.

[0002]

[Prior art]

 As a conventional technique of this type of mixer vehicle cleaning waste water storage box, there is one disclosed in Japanese Utility Model Publication No. 61-18983.

As shown in FIGS. 3 and 4, the above-described device is provided with a frame d1 separately near the turning position of the chute b in the rear part of the concrete mixer truck, and a pair of arm pieces f are provided on the side surfaces of the frame d1. A sewage collection box c is mounted between the pair of arm pieces f rotatably in the arrow direction (see FIG. 4) with a pin j.

The sewage collection box c can be locked in rotation by opening and closing a lid g attached to the frame d1.

Then, when the fresh concrete is discharged, the fresh concrete adhering to the flow surface of the chute b rotating around the flow guide a and the rotation center e (see FIG. 5) is washed early after the work, but is washed. Noro water is temporarily stored in the waste water storage box c, and after returning to the plant, the waste water storage box c is rotated and discarded.

[0006]

[Problems to be solved by the device]

 However, in the above-mentioned conventional technique, (1) the frame d1 is separately attached to the rear part of the mixer car and the turning position of the chute b, and the dirty water storage box c is attached to the frame d1, so the vehicle needs to be modified.

(2) Further, since the rotation of the waste water storage box c is limited to the rotation only in the vertical direction when the noro water is discharged, there is a problem that the stop position of the mixer car is also limited when the no water is discharged. It

(3) Further, since the chute b of the mixer car turns only within a range of 180 ° with respect to the center line h of the chute b, when the waste water storage box c is attached to the chassis frame d, As described above, it is necessary to make the turning angle of the chute b larger than the current rotation angle by α angle.

Therefore, when the sewage collection box c is attached, the rear part of the vehicle body is modified, or when the sewage collection box c is attached to the chassis frame d, a large modification work is performed to greatly change the turning angle of the chute b. There is a problem that is required.

Therefore, the present invention has been devised in view of the above-mentioned problems of the prior art, and does not require a major modification of the mixer truck for mounting the waste water storage box, and the waste water storage box can be stored by one-touch operation. The purpose is to provide a possible cleaning sewage box for mixer cars.

[0011]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the mixer vehicle cleaning waste water storage box according to the present invention has a U-shaped holder having a pair of frames on both sides in the vicinity of the turning position of the chute of the chassis frame parallel to the center line of the vehicle body. Is rotatably mounted in a horizontal direction via a hinge, and a sewage collection box is rotatably mounted between the pair of frames with pins, and a holder lock mechanism for fixing the holder at the storage position and a sewage collection box. The feature is that it has a lock mechanism for fixing the waste water storage box.

[0012]

[Action]

 When collecting water from the chute, the holder at the storage position is released by the holder lock mechanism, and then the holder is rotationally moved to the chute side in the direction B in FIG.

On the other hand, when storing the waste water container, when the holder is returned to the storage position, the holder locking mechanism automatically locks and fixes the holder.

When draining noro water from the waste water collection box, after unlocking the waste water collection box, rotate the waste water collection box to discharge the waste water, and return the waste water collection box to the horizontal position. Locked and fixed.

[0015]

【Example】

 An embodiment will be described with reference to FIGS. 1 and 2. The present invention stores a holder 4 rotatably mounted on a chassis frame 1, a waste water storage box 3 rotatably mounted on the holder 4, and a holder 4. It is composed of a holder lock mechanism 6 that can be locked at a position and a waste water storage box lock mechanism 5 that can lock the waste water storage box 3.

A mounting plate 23 of the hinge 2 is fixed to the chassis frame 1 near the turning position of the chute 7 and parallel to the center line of the vehicle body by a screw 24 or welding, and the hinge 2 has a pair of sides on both sides. A substantially U-shaped holder 4 having a first frame 41, which is a frame, and a second frame is attached rotatably in the horizontal direction.

Reference numeral 21 is a pin of the hinge 2, 22 is a rotation center axis of the hinge 2, D is a rotation center of the chute 1, and E is a center line of the chute 1.

A sewage collection box 3 is attached between the first frame 41 and the second frame of the holder 4 via a pin 33 so as to be vertically rotatable.

The holder lock mechanism 6 fixes the bracket 66 to the chassis frame 1 with screws 65 or welding, and the bracket 66 is provided with a first lever 61 having a hook 63 at its tip via a pin 63. A spring 62 is rotatably fixed, and a spring 62 is arranged between the hook 66 side of the first lever 61 and the bracket 66.

On the other hand, a handle 32 that engages with the hook claw 64 is fixed to the side surface of the dirty water storage box 3 on the first lever 61 side, and when the holder 4 returns to the storage position, the hook claw 64 moves the handle 42. The hook holder 4 is automatically locked.

On the contrary, when the lock is released, the lock is released only by tilting the first lever 61 in the direction of arrow C.

The sewage collection box lock mechanism 5 rotatably fixes a second lever 52 having a hook 51 at the tip thereof to the second frame 42 via a pin 54 so that the second frame 52 and the second lever 52 are connected to each other. A spring 53 is arranged between the second frames 42.

On the other hand, the handle 31 that engages with the hook claw 51 is fixed to the side surface of the waste water reservoir 3 on the side of the second lever 52, so that the hook 31 is handled in a substantially horizontal position. 31 is hooked and fixed, and the dirty water storage box 3 is automatically locked. Conversely, when the second lever 52 is operated in the X direction of the arrow, the locked state is released.

[0024]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. (1) The most important feature of the present invention is that the waste water storage box can be rotated and moved to the discharge position of the chute, so that no modification work of the vehicle body is required. Therefore, the installation work of the sewage collection box became easy. (2) When the sewage collection box is stored, the holder and sewage collection box lock mechanism automatically locks the holder and the sewage collection box with one-touch operation. It becomes convenient. (3) Since the structure of this wastewater storage box is extremely simple, it has very good workability, cleanability, and maintainability.
