Abstract

A spray pipe comprises two main pipes 1, 2 which will collapse into a flat member when no water is filled therein but will expand into a cylindrical member when filled with water. The main pipes 1, 2 are provided with a plurality of holes 11, 21 on the top for spraying and joined together by an auxiliary pipe 3. A string (4, Fig 3, 4) may be pulled through the pipe 3 to assist positioning of the spray pipe. The spray pipe is applicable to agriculture (Fig 2), fish ponds (Fig 3) and as a cooling pipe in chicken railing sheds (Fig 4). <IMAGE>

Description

TITLE: SPRAYING PIPE This invention relates to an improved spraying pipe.

It has been found that the conventional spraying pipe falls into two categories, i.e. the single-pipe and double-pipe. However, both categories are easily blown over by the wind and are liable to be distorted.

Furthermore, they can only be used in agriculture such as in the orchid and vegetable field. As to the fish pond and chicken raising shed, the conventional spraying pipes would be of no use. Besides, in case the spraying pipe is blown at one side, it will be slightly turned over thereby changing the track of the spraying water.

Hence, it is necessary to place stones to back up the spraying pipe thus requiring a lot of manpower.

The novel features which are characteristics of the invention, together with further objects and advantages thereof will be better understood from the following description considered in connection with the accompanied drawings and in which a preferred embodiment of the invention-is illustrated by way of example. It is to be expressly understood, however, that the drawings are for the purpose of illustration and description only and are not intended as a definition of the limits of the invention.

It is the primary object of the present invention to provide a spraying pipe which will not be blown over by the wind.

It is another object of the present invention to provide a spraying pipe which can be disposed easily.

It is still another object of the present invention to provide a spraying pipe which is suitable for use in agriculture.

It is still another object of the present invention to provide a spraying pipe which is adapted for use in fishing.

It is a further object of the present invention to provide a spraying pipe which is applicable to pasturage.

It is, therefore, an object of the present invention to provide an improved spraying pipe which may obviate and mitigate the above-mentioned drawbacks.

FIG. 1 is a perspective view of a spraying pipe for agricuture, fish pond and pasturage according to the present invention; FIG. 2 is a working view of the present invention FIG. 3 is a second working view of the present invention; FIG., 4 is a third working view of the present invention; and FIG. 5 is a prior art spraying pipe.

For purposes of promoting an understaning of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings.

Specific language will be used to describe same. It will, nevertheless, be understood that no limitation of the scope of the invention is thereby intended, such alternations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated herein being contemplated as would normally occur to one skilled in the art to which the invention relates.

With reference to the drawings and in particular to FIG. 1 thereof, the spraying pipe for agriculture, fish pond and pasturage according to the present invention comprises two main pipes 1 and 2 which will shrink into a flat member when no water is filled therein but will expand into a cylindrical member when filled with water.

The two main pipes 1 and 2 are joined together by an auxiliary pipe 3 and provided on the top with a plurality of spraying holes 11 and 21. The auxiliary pipe 3 has no spraying holes and is designed to increase the stability of the whole spraying pipe, prevent the spraying pipe from overthrown by wind and let a nylon string pass therethrough so as to enable the spraying pipe to be moved or hanged conveniently.

The auxiliary pipe 3, when filled with water, will increase the stability of the two main pipes 1 and 2 and maintain the track of the spraying water (see FIG. 2). In case, the wind blows from direction A (as shown in FIG.2), the main pipe 1 will be blown to lean towards direction B thereby changing the track of the spraying water. However, if the auxiliary pipe 3 is filled with water, it will prevent the main pipe 1 to lean towards direction B therey keeping the track of the spraying water in an ideal condition compared with the prior art.

Further, the present invention can be disposed conveniently. For example, when desired to dispose the spraying pipe in a fish pond, simply pass a nylon string 4 through the auxiliary pipe and then fix the two ends thereof to fixed rods or the like thus preventing the spraying pipe from sinking into the fish pond (see FIG. 3).

Similarly, the spraying pipe according to the present invention can also be applied to a chicken raising shed so as to decrease the temperature therein (as shown in FIG. 4).

Although this invention has been described with a certain degree of particularity, it is understood that the present disclosure is made by way of example only and that numerous changes in the construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.

Claims (5)
