Description

[Detailed description of the invention] The present invention relates to a pressurized liquid injection device, and the object of the present invention is to provide a pressurized chemical liquid injection device suitable for controlling termites, which nest inside wood and cause great damage to houses. It is something.

The conventional termite control method is to drill a hole of about 9 to 10 mm in wood and then pressurize a chemical solution into the hole, but the injection pressure of the solution is ^low at about 5 to 8 kg/cm Since there was a gap between the hole and the injection nozzle, there was a lot of loss of the chemical solution, and the permeation and diffusion range of the chemical solution was at most a radius of about 5 cm. Therefore, in order to obtain a sufficient effect, holes must be made at 10 cm intervals, but as the number of holes increases, the appearance of the building will be impaired, so the work will not be carried out in areas such as entrances and reception rooms. The disadvantage was that the necessary tools were not organized, making it impossible to work efficiently.

The present invention has been developed with this in mind. According to the present invention, the drawbacks of the conventional methods are eliminated and work can be carried out efficiently.

As shown in Fig. 1, the pressurized injection device of the present invention has a pressure pump 2 mounted on the upper stage of an upright frame 1, a chemical solution tank 3 mounted on the middle stage thereof, a component box 4 arranged on the lowest stage of the frame 1, and a pressure pump The inlet 5 of the frame 2 and the chemical tank 3 are connected by a flexible hose 6, and the injection nozzle 9 is detachably connected to the outlet 7 of the inlet 7 via a high-pressure hose 8.The upper end of the frame has a handle. 10, and on the lower side of the rectangular base at the lower end of the frame, stoppers 11 are provided at both front corners, and a pair of wheels (on the back side of both stoppers 11) are provided at both rear corners. (not shown in the figure) is attached. The frame, which stands stably upright with a pair of stoppers and a pair of wheels, can be tilted rearward with a handle 10, and the entire device can be moved freely and easily using the pair of wheels.
Further, a drill sac 12 is attached to the frame on the side of the chemical tank 3, and an electric drill 13 is attached to the frame.
are becoming attracted to this.

When using the pressurized injection device of the present invention to exterminate termites, first use an electric drill to drill a hole with a diameter of 3 mm, which is smaller than conventional holes, in wood. The distance between the holes should be about 60 cm.

Insert the injection nozzle 9 into this hole and drive it with a hammer to firmly fix it to the wood. The injection nozzle 9 is connected to the discharge port 7 of the pressure pump via the high pressure hose 8.
Combine with. By moving the pressure pump operation handle 14, the chemical solution in the chemical solution tank 3 can be easily dispensed.
Pressurized to 100-150Kg/ ^cm2 . In this case, since the nozzle is fixed within the wood, the chemical solution is diffused in the direction of the fibers without flowing out.

The device of this invention enables high-pressure injection of chemical solutions, so the chemical solution can be injected over a wider area 6 to 10 times larger than conventional ones through a hole with a smaller diameter, and the work can be completed in a short time with minimal damage to the appearance. can.

The device of the present invention has a compact structure with an upright frame, is lightweight and does not take up much space, the tool parts necessary for the work can be moved together, the handle of the pressure pump is at an appropriate height for the human body, and the injection pump The nozzle can be freely extended at the work site.
Able to work extremely efficiently.

The device of the present invention has great practical value because it can be applied not only to termite control but also to a wide range of applications such as resin injection into objects such as wood, antiseptic treatment, waterproof treatment, etc.
