Description

  The present invention relates to a floor plate cleaning machine and a floor plate cleaning method.

  A plastic floor board as shown in FIGS. 1 and 2 is provided by the present applicant. This plastic floor has the feature that, for example, a truck or other vehicle can pass freely just by laying it on a muddy and soft ground, which is indispensable for work sites such as construction sites. It is an indispensable item.

  This flooring is usually collected after use at a construction site, and then reused after cleaning. However, there is a problem with cleaning a large amount of flooring that has been laid on the construction site and covered with mud. .

  Most of the floorboards used at construction sites are large in size and weight. For example, a floorboard of 39 kg per piece and 2.4 meters in length is widely used. Conventionally, these large and heavy floorboards are washed one by one by turning them upside down with human power, so there are problems in terms of health such as time and labor costs for washing and back pain of workers. It was.

  Although attempts have been made to develop a washing machine to solve these problems, no company has yet developed a washing machine with excellent cost performance.

Accordingly, in view of the above-described problems, an object of the present invention is a washing machine that can efficiently and efficiently clean a floorboard used in various work sites such as a construction site at a low cost. It is to provide a washing machine that can be manufactured.
Another object of the present invention is to provide a method for cleaning a floor board that enables a floor board used in various work sites such as a construction site to be cleaned in a labor-saving manner and in a short time.

  The purpose of the present invention is to provide a first moving means that allows the floor plate to be cleaned to move, a second moving means that makes the floor plate movable, and a path from the first moving means to the second moving means. This is achieved by a floor plate washer having a cleaning liquid ejecting means provided on the way.

<Effect of making the second roller conveyor rotatable>
By draining the floor plate together with the second roller conveyor, draining after the floor plate cleaning becomes easy. In the case of cleaning by a conventional method, there is a problem that sewage during cleaning is accumulated on the floorboard.
In addition, by inverting (turning over) the floor plate together with the second roller conveyor, the cleaning result / cleaning condition on the lower surface side of the floor plate can be easily confirmed. In the case of cleaning by the conventional method, since a large weight and large size floorboard is turned over only by human power, there is a problem in safety and workability during cleaning.
In addition, when stacking the washed floorboards on the pallet, it becomes easy to unify the orientation of the front and back surfaces of the floorboard (for example, all the floorboards have a chevron pattern facing down). Can be rented or stored. In addition, it is strongly required to provide the front and back of the floorboard in a unified state so that the floorboard can be laid immediately on site.

<Effect of making the cleaning liquid injection device movable by casters>
By providing a moving means such as a caster, the cleaning liquid ejecting apparatus can be moved anywhere in the washing machine, and it is possible to easily and quickly cope with a case where only a part of the floorboard is to be washed intensively.
Further, when there is a portion that is not cleaned by checking the back surface, it is possible to move the cleaning liquid ejecting apparatus, so that it is not necessary to move the heavy laying board one by one, and efficient cleaning becomes possible.

<Effect of making the injection nozzle movable>
Since the entire surface can be cleaned with a small number of nozzles by moving the nozzle, the amount of water used is reduced. Therefore, it is possible to perform cleaning with low resource and low cost.
In addition, by reducing the amount of water used for cleaning the floorboard, a general pump owned by a rental company can be used.
In addition, if there is a portion that is not cleaned by checking the back surface, the nozzle can be moved, so there is no need to move a heavy bed.

<Effects of adopting a rotation-adjustable nozzle>
When a rotating nozzle is used, the spray range is widened, so that efficient cleaning can be performed. As a result, the number of nozzles to be equipped can be reduced, and as a result, the amount of water required for cleaning can be reduced.
