Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> This invention relates to improvements in concrete washing equipment.

<Prior Art> The present applicant proposed the following concrete washing device in the application of Japanese Patent Laid-Open No. 59-026634.

In other words, a suction section consisting of a plurality of suction nozzles arranged in parallel in the width direction of the main body with rollers installed at the front and rear is provided, and an adjustment plate and a holding plate are provided on the front side of the suction section to form a suction space, and the adjustment plate This concrete washing device is characterized in that an air circulation hole is provided in the concrete washing device so that the amount of external air sucked into the suction nozzle can be adjusted, and a spraying section consisting of a spraying vibrator is provided in front of the suctioning section.

In this way, in the conventional device, a suction space is formed by providing an adjustment plate and a presser plate in front of the suction part, and an air circulation hole is provided in the adjustment plate, making it possible to adjust the amount of external air sucked into the suction nozzle. In addition, a spray section consisting of a spray vibrator was provided in front of the suction section to spray water.

<Problems to be Solved by the Invention> However, when the above device is actually used, this configuration cannot necessarily eliminate the problem of aggregate chewing, and since the water is sprayed directly from the spray vibrator, the water pressure directly sprays the concrete. This also resulted in the inconvenience of roughening the surface and requiring a large amount of water.

<Means for Solving the Problems> The present invention aims to provide a concrete washing device that eliminates the above-mentioned disadvantages of conventional devices.This invention particularly improves the spraying section, and has the following configuration. do.

In other words, a roller is rotatably fixed to the front and rear ends between a pair of side plates to support it, and a suction section is installed at the front between the two rollers, and a water spray section is installed at the rear through a gap for concrete washing. This concrete washing device is characterized in that a box having a water sprinkling hole at the bottom is provided below the water sprinkling part, and a water supply pipe is arranged above the box.

<Examples> Examples of the present invention will be described below based on the drawings. As shown in FIG. 1, the washing device A has a pair of left and right side plates 11.
Rollers 12 and 12 supporting the rollers 12 and 11 are rotatably supported at the front and rear ends of the rollers 11 and 11, respectively.

A suction part 13 is installed in the front part between both rollers 12 and 12, and a water spray part 153 is installed in the rear part through the gap part 14.The suction part 13 is installed in the air adjustment chamber 16 as shown in FIGS.
and the air collection chamber 17 are connected by four branch pipes 171. An 18-portion gate-shaped handle is installed at the upper part between the side plates 11 and 11. A suction pipe 19 is installed obliquely upward from the upper surface of the air collection chamber 17, and a suction pump (both not shown) outside the machine is connected to the upper end of the suction pipe 19 via a suction pipe.

On the front surface of the inlet 20 of the air adjustment chamber 16, a comb-shaped horizontally uneven plate 21 and a comb-like vertically uneven plate 22 as shown in FIGS. 4 and 5 are provided. Recess 2
3 is made to face the other convex portion 24.

The horizontally uneven plate 21 is formed by cutting out the tip of the bottom plate 161 of the air adjustment chamber 16 in a comb shape. The vertically uneven plate z2 has thumbscrews 2 inserted into horizontal grooves 25 made in the side plate 11.11 above the inlet 20.
6. Install vertically.

The longitudinal position of the thumbscrew 26 can be adjusted within the range within the lateral groove 25. When the thumbscrew 26 is placed at the rear end as shown in FIG.
comes to the tip of. When the thumb screw z6 is moved to the front end, that is, to the left in FIG. 2, the vertically uneven plate 22 becomes the inner end of the recess 23 of the horizontally uneven plate 21, as shown in FIG. This double concave white board 21.2
Depending on the positional relationship between the two, the suction force can be adjusted, and at the same time,
Prevents chewing of aggregates such as sand and pebbles.

As shown in FIGS. 2 and 3, the water sprinkling section 15 is made up of a box 28 that is open at the top and divided into two chambers by a central wall 27. The rear chamber 29 is a water storage chamber 30, above which a water supply pipe 31 is disposed, and a plurality of small holes are formed along the lower side of the central wall 27 to serve as water sprinkling holes 32. The front chamber 33 is a preliminary chamber 34, and its bottom plate 34
1 is a part that functions as a finishing trowel as described later. A vertical groove 35' is formed near the outer edge of the side wall of the preliminary chamber 34, and a shaft 36 installed between the side plates 11 and 11 is passed through the vertical groove 35', so that the box body 28 is installed so as to be freely tiltable. The shaft 36 works in the vertical direction within the vertical groove 35', and the mounting position can also be adjusted in the front-back direction.
height H. A vertical groove 37 is also formed near the outer edge of the side wall of the water storage chamber 30, and the shaft 36 is passed through the vertical groove 37 by turning the box body 28 upside down.

If the front and back are reversed, the water storage chamber 30 will open as shown in Figure 3.
The rear wall 36 serves as a boundary between the gap 14 and the air adjustment chamber 16. By reversing in this way, the cavity 14
When the height of the boundary changes, the suction force of the suction section 13 changes as will be described later.

Next, how to use the washing device A will be explained. First, small pieces of granite, marble, or other aggregates are placed in a mortar mixture of cement and sand, water is added, and the mixture is poured. After flushing, the cleaning work using this device A begins. Watering section 15
The device A is moved in the direction of the arrow a while water is flowing from the drain and the suction unit 13 is suctioning the water. This movement procedure is similar to cleaning the floor with a vacuum cleaner. As the washing device A moves, water flows onto the concrete surface, and at the same time, suction force is applied to the concrete surface by the suction unit 13. When the suction force works, the gap 14 between the suction part 13 and the water spray part 15
becomes a negative pressure and acts as a suction space. The unsolidified concrete surface becomes fluid due to the sprayed water. Since the negative pressure in the suction space acts on the fluidized mortar, the mortar moves along with the water into the suction space, where it is sucked up and the aggregate is exposed. The exposed aggregate is lightly pushed by the bottom plate 341 of the sprinkler section 15 and the rollers 12.12, and is submerged and stabilized.

Water is supplied from the watering vibrator 31 to the water storage chamber 30 of the watering part 15, and flows from the watering hole 32 onto the concrete surface. After the water once enters the water storage chamber 30, it naturally falls from the water sprinkling hole 32.

Since water is sprinkled gradually in this way, it does not damage the concrete surface and only requires a small amount.

The sprayed water is sucked up by the negative pressure in the cavity 14 and sucked into the suction part 13 .

<Effects of the Invention> As explained above, the present invention is a concrete washing device in which the water sprinkling part is particularly improved so that water is first dropped from the water spray vibrator into the water storage chamber and then allowed to fall naturally from the water sprinkling hole. Therefore, unlike conventional devices, water is sprinkled gradually, so water can be sprinkled without roughening the concrete surface, and a small amount of water is required, which is a great effect.

This is a major practical achievement. In addition, sewage is sucked out from the concrete surface by suction, but this sewage is washed away by water that is constantly sprayed from the sprinkler section. Therefore, no sewage remains on the concrete surface, resulting in a clean finish.
