Abstract

PROBLEM TO BE SOLVED: To reduce an operating procedure for easy handling and for high reliability of a scaffold by eliminating the need for a water introduction hatch and a draining hatch. SOLUTION: A mounting plate 2 and a side plate 3 are mounted to a flat box-shaped top plate 1 and a bottom plate 4 is mounted to the side plate. A fixing pin 22 is provided below and in front of the top plate and a lever 20 with a weight 19 and a lever 5 attached thereto is attached to the underside of the bottom plate. A shaft 9 and a stopper 10 are attached to a spring plate 11 and a container provided at its top with packing 13 and a fixing pin hole 21 is mounted to the spring plate. Bearings A7 and B8 are attached to an arm 6 and another bearing A is mounted between the top plate and the bottom plate by means of a bolt 14 and a nut 15. The shaft 9 is inserted into still another bearing B and locked in place by means of a washer 18 and a split pin 16. The container is moved up and down by means of the lever relative to the fixed top plate to simultaneously close and fix the container and wash water is drained by tilting the container from a horizontal position.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hatchless container in which a water inlet hatch and a drain hatch of a water washing container of a concrete mixer truck are eliminated.

[0002]

2. Description of the Related Art Conventionally, as a container for washing water of a concrete mixer truck, a box-shaped container provided with a water inlet hatch and a drainage hatch at the rear of a vehicle body has been used in a drawer type or a rotary type. .

[0003]

This has the following disadvantages. (B) After discharging the ready-mixed concrete from the concrete mixer truck, it became quite heavy to wash away the ready-mixed concrete adhering to the drum mouth, chute, and auxiliary chute. Buckets and bags were extremely powerful. (B) A drawer-type container equipped with an input hatch and a drainage hatch requires first removing the fixing pin at the time of use, pulling out and rotating the container to open the input hatch, so that there are many procedures. It was quite in the way. (C) When using a rotating box-shaped container, the fixing pin is removed during use and the container is rotated to open the water inlet hatch, so that the water inlet hatch was quite obstructive. (D) The drawer-type and rotary-type box-shaped container's water inlet hatch
It will also be a foothold for work, but for fixing with pins together,
There was play. The present invention has been made to eliminate these disadvantages.

[0004]

Means for Solving the Problems A top plate (1) in which a mounting plate (2) and a side plate (3) are mounted on a flat plate-shaped top plate (1) and a bottom plate (4) is mounted on the side plate (3). ), A fixing pin (22) is provided, and a weight (19) and a lever (20) are attached to a lever (5) under the bottom plate (4).
Attach the shaft (9) and the stopper (10) to the spring plate (11).
The arm (6) has a bearing A (7), a bearing B, and a container (12) provided with a fixing pin hole (21).
Attach (8), between the top plate (1) and the bottom plate (4)
The bearing A (7) is attached with the bolt shaft (14) and the nut (15). The shaft (9) is inserted into the bearing B (8), and stopped with the washer (18) and the split pin (16). The present invention has the above-described configuration, and simultaneously performs sealing and fixing by moving the container up and down with a lever, washing water is drained by tilting the container from a horizontal position, and an input hatch and a drain hatch are unnecessary. This is a hatchless container for washing a concrete mixer truck.

[0005]

Embodiments of the present invention will be described below. Attach the mounting plate (2) and the side plate (3) to the flat box-shaped top plate (1), mount the bottom plate (4) to the side plate (3), and fix the fixing pin (22) below the front plate (1). ), And a lever (20) with a weight (19) and a lever (5) attached below the bottom plate (4). A shaft (9) and a stopper (10) are attached to a spring plate (11), and An arm (6) for attaching a container (12) provided with a packing (13) and a fixing pin hole (21).
The bearing A (7) and the bearing B (8) are attached to the top plate (1) and the bottom plate (4).
4) and the nut (15), insert the shaft (9) into the bearing B (8), and attach the washer (18) and the split pin (1).
Stop at 6). The present invention has the above structure, and

[2] When the lever (20) is used to tilt the lever (5) from the storage position, the container (12) is released from the top plate (1). The bolt (5) and the lever (20) are bolted to the mixer truck chassis with the mounting plate (2) so that they are directly above the container (12). After the ready-mixed concrete is stopped, the ready-mixed concrete attached to the drum port, chute and auxiliary chute is washed away, and the washing water is removed from the container (1).
In step 2), when the container (12) moves on a slope or the like, the fixing pin (22) provided below the top plate (1) is inserted into the fixing pin hole (21) and fixed. If the container is stored by rotating it again and the lever (20) is used to lift the lever (5), the container (12) is lifted up, and is sealed and fixed by the action of the packing (13) and the spring plate (11). When draining, tilt lever (5) with lever (20), rotate arm (6), and then tilt container (6). 9) is set at the lower part where it is slightly offset from the center, the stopper (10) is set so that the container rotates from the horizontal position to the point where the washing water is discharged, and the top plate (1) is Become a reliable platform without play.

[0006]

According to the present invention, the packing (13) is provided above the container (12), and the spring plate (11) is provided below the container (12). Inlet and drainage and storage can be done simply by rotating the lever and the container, there is no hatch, so it is simple and does not interfere with work, and there is no need to open and close.Drainage treatment can be tilted so that the container can be turned over Easy to wash, the top plate (1) is firmly fixed to the mixer truck chassis by the mounting plate (2), so it is highly reliable as a scaffold at the time of work. This unit also has a mounting plate (2) Container (12) and bearing A (7) that can be easily attached and detached because they are bolted to the chassis.
Repair and replacement are easy because the bolts and nuts are also used.
