Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cleaning dirt on the surface of a rotary drum of a concrete mixer truck or the like by using the rotation of the drum or automatically performing care such as waxing.

[0002]

2. Description of the Related Art Rotary drums (hereinafter referred to as "drums") of concrete mixer trucks and the like become dirty with ready-mixed concrete when loading and unloading ready-mixed concrete, and are used for outdoor work.
Drums with many elements that make the whole concrete mixer truck dirty with rain, snow, mud and dust have a very large surface area,
Hand washing with a hand brush is a great effort.Therefore, a roll-type was used, in which the back of the drum, which is particularly easily soiled, was cut off with a piece of cloth or oiled to prevent splashing of fresh concrete. The washing machine had a drum belly shape, and there was no device that could automatically wash the entire drum because the inspection lid and the bolts that fix it (hereinafter referred to as protrusions) protruded from the drum surface.

[0003]

This has the following disadvantages. (B) The method of hanging a piece of cloth on the drum is that if the time elapses, the piece of cloth itself becomes black and stains, and since it is rubbed between the drum and the drum, the paint on the drum becomes thinner. It seemed to hurt. (B) Applying oil and waxing was also a manual operation and did not ease the labor. (C) The roll-type washing machine did not wash the entire drum. The present invention has been made to eliminate these disadvantages.

[0004]

A roll A (1) around which a sponge (10) is wound is attached to a frame A (13). A cushion is provided around a bearing (9) of a roll B (2) and a roll C (3). Roll B to attach rubber (12)
Attach a sponge (10) to the surface of (2) and roll C
The brush (1) tilted in the direction opposite to the rotation direction on the surface of (3)
1) Attach, Roll B on Frame C (15)
(2) The roll C (3) is attached to the frame C (15) by making contact with moderate pressure so that the roll C (3) rotates, and the shaft D (7) is attached to the frame A (13). The frame is set so that the drive wheel (16) attached to the bevel gear (28) through the shaft C (6) is located at the center of the entire device in conjunction with the gear (29) attached to the frame B (14). Attach the running wheel (17), the running wheel auxiliary rod (19) and the hose clip (18) to the B (14).
(5), and a spring (27) was provided between the frame A (13) and the shaft C (6). The present invention is an automatic washing machine for a rotating drum having the above configuration.

[0005]

Embodiments of the present invention will be described below. (A) A roll A (1) around which a sponge (10) is wound is attached to a frame A (13), and a gear is attached to a shaft A (4). (B) Roller B (2) and Roller C (3) bearing (9)
Attach cushion rubber (12) around. (C) A sponge (10) is attached to the surface of the roll B, and a brush (11) inclined in a direction opposite to the rotation direction is attached to the surface of the roll C. (D) Roll B (2) and roll C (3) are brought into contact with frame C (15) with moderate pressure so that they rotate, and shaft D (7) is mounted. (E) Gear (29) axis C on frame B (14)
(6) Running wheel (17) Running wheel auxiliary rod (19) Attach hose clip. (F) The bevel gear (28) to which the drive wheel (16) is attached is attached so as to interlock with the gear of the shaft C (6). (G) The frame A (13) and the frame B (14) are connected by a shaft B (5), and a spring (27) is attached between the frame A (13) and the shaft C (6). (H) The frame A (13) and the frame C (15) are connected by the axis D (7). The present invention is configured as described above. When this is used, as shown in FIG. 2, a shaft C is disposed between the drum (24) and the handrail (23).
While holding the spring (27) attached to (6), insert the drive wheel (16) and the device into place, put the running wheel on the handrail, and insert the hose with the hose clip (18),
The power is transmitted from the roll A (1) to the drive wheel (16) via the gear (29) by the rotating force of the drum, which is used while discharging water, and the apparatus moves in the axial direction of the drum. The driving wheel is set at the center of the entire device so that the corners of the handrail (23) and the modified handrail (22) can be easily moved as in 3, and the traveling wheel assisting rod acts so that the traveling wheel does not derail the corner. It is. When the drum is rotating from top to bottom as shown in FIG. 5, the pressure of the roll B (2) against the drum is high, the pressure of the roll C (3) is low, and the rolls B (2) and (3) The brush (11) rotates in the opposite direction to the rotation direction of the drum, but the brush (11) rotates in the forward direction with respect to the drum.
Wash while pouring water to the back of the drum.
When the drum rotates from bottom to top, roll B
Since the pressure of (2) decreases and the pressure of roll C (3) increases, the frictional force between the drums of rolls B (2) and C (3) becomes almost the same, and almost no rotation occurs. The bearing (9) of the roll B (2) and the roll C (3), which rotates only at the moment of passing through the protrusion and does not break.
The rubber (12) around the roller acts to reduce the impact from the protrusion of the drum and maintain the contact pressure between the rolls B (2) and C (3).
(2) Since the roll C moves from the back of the drum to the entire surface of the drum to remove the water on the surface of the drum after washing, it has a wiping effect. When performing waxing, a spray type is used instead of water. What is necessary is to move the device while applying the wax.

[0006]

This device can be easily attached and detached between the drum and the handrail, and if the hose is inserted into the hose clip, the faucet can be adjusted and the drum can be rotated forward and backward only by operating the lever. This machine can be used when picking up if the drum becomes dirty when the great effort by the brush etc. disappears.
The axis E (8) of the roll B (2) and the roll C (3) and the axis D (7) of the frame C (15) can be easily detached by expanding the frame because the entire frame is made of an elastic material such as metal. Easy replacement and repair.
