Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water absorbing machine for removing water pools in sports fields, schoolyards, baseball fields, tennis courts, greens of golf courses and other courts for competition.

[0002]

2. Description of the Related Art Various outdoor exercise facilities have been devised in such a way that they can be used quickly so that they can be used immediately after raining, so that they can be treated well. For example, for sports grounds, etc., a material that has high water permeability and appropriate elasticity is embedded in an appropriate thickness, and soil of appropriate hardness is placed on the ground surface, etc. It has been constructed so that it can be used after a short period of time. However, in cases such as after long rains, or when it rained more than expected,
Immediate use is often difficult.

In the above cases, especially in the case of physical education, games or various competitions where the use start time is fixed, the overall schedule will be wrong, and the water pool will be removed as soon as possible. There is a need. Generally, in such a case, waste cloth, mop, beach, etc. are generally used in such cases.
Water pools are often removed using human tactics. Such work is inefficient and requires a large number of workers, so rapid work cannot be expected.

Further, in such a conventional method, since sand and mud are kneaded, even if the water pool can be removed, the ground surface is roughened and a good result is often not obtained.
Therefore, it is often necessary to perform extra work such as sprinkling sand to re-level the surface.

[0005]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned drawbacks of the prior art and is capable of efficiently and quickly removing water without roughening the ground surface. The purpose is to provide.

[0006]

The gist of the structure of the present invention is a water-absorbing roller rotatably mounted on a frame, the water-absorbing roller having a water-absorbing material wound around the outer periphery thereof.
A squeezing roller mounted on the frame in parallel with the water absorbing roller, the squeezing roller being pressed against the outer periphery so as to continuously press the water absorbing material while rotating in the opposite direction with the rotation of the water absorbing roller. And a water receiving tank for receiving the water squeezed by the squeezing roller.

The water-absorbing roller comprises, for example, a cylindrical portion, a central axis located at the center of the cylindrical portion, and a disc that closes both ends of the cylindrical portion and has the central axis fixed at its center. Can be configured. Needless to say, spokes may be used instead of the discs. The water absorbing material is a band-shaped sponge member, which is wound around the outer circumference of the cylindrical portion of the water absorbing roller. This is an open-cell porous strip made of a material having a hydrophilic property, and a member having elasticity is suitable. Since sponge-like polyurethane foam and the like have been commercialized, this can be used.

The squeezing roller may be a roller having substantially the same length as the water absorbing roller and having a diameter considerably smaller than that. Needless to say, this is a floating roller, and is configured so as to rotate smoothly in the opposite direction as the water absorbing roller rotates. This squeezing roller may be a simple cylinder or a cylinder, but if a cylindrical body is used and a configuration is provided with a large number of drainage holes penetrating the inside and the outside of the squeezing roller, the squeezing operation of the water-absorbing material externally mounted on the outer periphery of the water-absorbing roller can be performed. It is more convenient because water can flow out through the drain hole.

Needless to say, the water receiving tank is located below the squeezing roller, and its upper opening is positioned so as to receive the water that flows down after being squeezed by the squeezing roller.
In addition, a drainage pipe will be placed underneath and a cock will be installed on it. When the water receiving tank is full of water or when the water absorption work is completed,
Drain the water in a suitable drainage facility directly from the drainage pipe or by connecting a hose. The water receiving tank can be detachably attached to the frame or the shaft of the squeezing roller, if necessary. In this way, when the water receiving tank is full, the water receiving tank can be replaced to allow the water absorbing operation to be continued.

The frame, the water receiving tank, the water received and held by the water receiving tank, and the squeezing roller are located in the frame where the squeezing roller is located between the squeezing roller and the water absorbing roller. Small wheels may be provided to support the weight of the roller with the water absorbing roller. The small wheel may be a single wheel or a pair of small wheels arranged in parallel. Depending on the scale of the water absorber to be constructed, consider whether to attach a small wheel, one wheel or two wheels.

Further, as described above, when the small wheels are formed on the frame, this water absorbing machine is equipped with a driving means for rotating and driving the water absorbing roller in addition to the manual pushing type, and is self-propelled. can do. As the driving means, a power source such as an electric motor and a storage battery or a small internal combustion engine can be used. In addition to such driving means, it is possible to incorporate an operating mechanism such as a wireless remote control system or an operating system capable of performing automatic operation along a buried wireless induction antenna.

In the case where the water absorber is manually pushed in the frame, the drive means is provided only as an auxiliary means, or the drive means is self-propelled, it is possible to absorb water. It is convenient to construct the handle at the end opposite to the roller.

[0013]

Since the present invention is constructed as described above, a baseball field, an athletic field, a tennis court or the like, or the grounds or golf courses of various schools will have water pools on the surface due to rainfall. In this case, when the water absorber of the present invention is run, the water absorbent material comes into contact with the water in the water pool as the water absorbent roller rolls, absorbs the water absorbent material, and raises the area where the water absorbent material is absorbed. The water is squeezed by the squeezing roller that is pressed against the water, and the water is received by the water receiving tank and temporarily stored.

This is the same regardless of whether the water absorber is of a manually-operated type or a self-propelled type. If it is a hand push type, if the handle is configured, it can be grasped and pushed to walk. Needless to say, if it is a self-propelled type, it is driven by driving means.

Needless to say, the drainage of the water receiving tank is
Perform after moving to the designated drainage facility. If a drainage pipe and cock are provided, open the cock. If the water receiving tank itself is detachably installed, replace it with a new water receiving tank when the water in the water receiving tank reaches an appropriate level, and then knock down the removed water receiving tank to drain the water. You can also do such things.

If this water absorber is constructed as a push-pull type, as described above, it is economical, but the labor of the operator is large. The self-propelled type is advantageous in terms of labor. When the drive mechanism and the operation mechanism are provided, automatic operation becomes possible, and efficient automatic water absorption can be achieved by operating the water absorber along a predetermined or arbitrary path. Therefore, not only the labor of the operator is reduced, but also there is no possibility that the footprint is generated by the walking of the operator.

You can easily and speedily remove water from those puddle and restore the ground or arena to immediate use for that purpose.

When the water absorber is gripped by the rear grips 7, 7 and pushed to move the water absorption roller 2, and the water absorption roller 2 is rolled, the water absorption member 3 wound around the outer periphery of the water absorption member 3 comes into contact with the ground. Is in contact with the water in the water pool, absorbs the water, and absorbs the water.
Then, it further rises as the water absorbing roller 2 continues rolling. In this way, the water absorbing material 3 is squeezed by the squeezing roller 5 that is in pressure contact with the water absorbing material 3, and the water that has been absorbed and held flows down into the water receiving tank 6 and is received.

If the area requiring water absorption is continuously pushed and moved as described above, the water accumulated at the passing position is absorbed by the water absorbing material 3, is squeezed by the squeezing roller 5, and is stored in the water receiving tank 6. It will be accepted and temporarily stored. Since the small wheels 9 are provided even if a considerable amount of water enters the water receiving tank 6, the weight of each part and the weight of the water will be received by the water absorbing roller 2 and the small wheels 9, which imposes a burden on the operator. I won't. When water absorption in all necessary areas is completed, or when the water receiving tank 6 is filled with water, the water is moved to a place where a predetermined drainage facility is provided and drained. The drainage is performed by connecting a hose to the drainage pipe 8 and opening the cock 18.
