Description

[Detailed Description of the Invention] This invention relates to a water removal machine that removes rainwater accumulated in grounds and the like.

Conventionally, large-sized water removal machines of this kind are known that use vacuum cleaners to remove water, but these large-sized water removal machines are not only extremely expensive, but also complicated to handle. It is not widely used.

However, when removing water from grounds etc.
Normally, water is removed by repeatedly using a piece of sponge or a rag to absorb water, then squeezing it to absorb more water, but such water removal methods require a lot of time and effort. It was necessary.

In view of the above circumstances, the present inventor previously proposed in Japanese Patent Application No. 57-57614 that it is easy to handle,
He proposed the development of a water remover that could be used even by small children and could remove water in a short amount of time.

That is, a frame supports a pair of wheels, a cylindrical water-absorbing body such as a sponge is provided between these wheels, and a water receiving tank is supported inside the water-absorbing body, while the outer circumference of the water-absorbing body is supported on the frame. A squeezing roller that comes into contact with the surface is installed, and during water removal work, the frame is gripped and the wheels are run to absorb water with the water absorbing body, and the absorbed water is squeezed with the roller, and the inner He proposed a water remover that allows water to fall and collect in a water tank.

By the way, since the water absorbent body is made of a soft material such as sponge, if the squeezing roller is kept in constant contact with the water absorbent body, the water absorbent body may be deformed and damaged, and the water absorbent body may deteriorate early. Therefore, the squeezing roller must be brought into contact with the outer circumferential surface of the water absorbent body when performing water removal work, and must be held in a non-contact position with respect to the water absorbent body when not working.

However, in the water remover, it is troublesome to switch the squeezing roller between a contact position and a non-contact position with respect to the water absorbent body, which makes it inconvenient to handle.

In order to solve the above-mentioned problems, the present invention aims to improve the water remover, to easily switch the squeezing roller to the water absorbing body, and to improve the ease of handling.

More specifically, it includes a frame and a pair of wheels supported by the frame, a cylindrical water absorbing body such as a sponge is provided between these wheels, and a water receiving tank is supported inside the water absorbing body, A support arm is pivotally supported by the frame so as to be freely swingable, a grounding portion is formed at one end of the support arm around the pivot portion, and a squeezing roller is supported at the other end;
A stopper mechanism is provided between the squeezing roller and the frame to urge the arm so that the squeezing roller comes into contact with the water absorbing body, and to hold the squeezing roller in a non-contact position with respect to the water absorbing body. That is.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The water remover of the present invention will be explained below with reference to embodiments shown in the drawings.

A cylindrical mesh body 4 having a large number of small holes 4a is supported concentrically with the wheels 2, 2 at an intermediate portion of the wheels 2, 2, and around the outer periphery of this mesh body 4,
A water absorbent material 5 such as a sponge is wrapped around it.

This water absorbing body 5 is provided so that a part of its outer peripheral surface bulges out in the radial direction from the outer diameter of the wheels 2, 2, and thus when the water absorbing body 5 is compressed when it touches the ground and is separated from the ground. That is, when the water absorbent body 5 is released from the compressed state and swells, it absorbs water on the ground.

Further, between the wheels 2 on the inside of the net-like body 4, a water receiving tank 6 having an opening 6a at the top is supported via a connecting shaft 3 provided between the wheels 2 and 2.

The upper part of the water tank 6 near the opening 6a side is freely inserted and supported by the connecting shaft 3, and the opening 6a is always oriented upward due to the weight of the water tank 6, and the bottom part is directed downward. When the water absorbing body 5 is squeezed by a squeezing roller to be described later,
The water squeezed out from the water absorbing body 5 is received and stored in the water receiving tank 6.

A support arm 7 having a U-shape is pivotably supported on the frame 1 via a shaft 8, and
A grounding portion 7a is formed at one end of the arm 7 centered on the pivot shaft 8, and a squeezing roller 9 is formed at the other end on the open side.
while supporting the grounding portion 7a of the arm 7.
A tension spring 10 is interposed between the side and the frame 1 to press the squeezing roller 9 against the outer circumferential surface of the water absorbing body 5 and energizing it to squeeze out the water absorbed by the water absorbing body 5. It is.
