Description

Detailed Description of the Invention

[0001]

[Industrial application] A high-pressure pump is driven by an engine, a motor, etc., and a high-pressure fluid (water, hot water, detergent mixture,
Various types of high-pressure cleaners that inject various kinds of machinery such as steam, air, and other fluids) to clean civil engineering and construction machinery, automobiles, fishing nets, and other items very efficiently are used. (EN) Provided is a lance for cleaning a narrow area of a high-pressure cleaning machine, which is capable of easily and efficiently cleaning a narrow position or location of an object to be cleaned.

2. Description of the Related Art Among various objects to be subjected to high-pressure washing, radiators of engines for various civil engineering and construction machines are heavily contaminated because they are used at construction sites, and need to be cleaned frequently. It was overheated and failed, which caused damage to the expensive engine, but since the radiator is usually installed in a narrow position close to the engine, it is difficult to insert with a conventional lance with a nozzle at the tip, and However, there is a problem that the conventional nozzle cannot clean well.

That is, when cleaning a radiator by fluid injection from a nozzle attached to the tip of a conventional lance, the cleaning trajectory due to the injection from the nozzle becomes linear or streak, so that a radiator with a wide flat surface (product) is used. It was difficult to clean the entire surface, and it took time.

Although the jet fluid can be made extremely strong, the jet fluid concentrates and hits a small washing portion, so that there is a drawback that the thin metal plate (fin) of the radiator is crushed or deformed to damage the radiator. .

In particular, since the radiator is installed in a narrow space close to the engine, the clearance around the radiator is naturally narrow, so that it is difficult to insert the conventional lance with a nozzle, and even if the lance can be inserted, the nozzle can be inserted. There were many problems such as no nozzles or damage to the fins by the nozzle.

Further, since the conventional nozzle is attached to the tip of the lance and only jets forward,
Even if it could be inserted into the narrow gap described above, it could not be ejected to the fins located on the side.

There is also a type in which the tip of the lance is bent in the lateral direction and a nozzle is attached to the tip, but since the gap is narrow, the tip of the lance cannot be rotated in the gap. It could not be applied for cleaning narrow gaps.

As a result of the above, in the past, it was unavoidable that the radiator was removed one by one, or the peripheral equipment was removed to widen the gap, and cleaning was carried out, but civil engineering and construction machinery, etc., are used almost daily. Because it needs cleaning
It took a lot of time and effort, was inefficient, and became a major issue.

The high-pressure washing machine is also used for washing nets such as fishing nets, glue nets, and wire nets, fences, fences, lattices, and the like. Since the space is large and large, most of the jetted fluid in the conventional nozzle blows through the space and collides only slightly with the composition, so that there is a problem that the cleaning efficiency with respect to the amount of fluid used is extremely low.

[0010]

Therefore, the present invention effectively solves the above-mentioned conventional problems by the following means. That is, according to the present invention, in a lance attached to a high-pressure fluid jet gun of various high-pressure washers, a plurality of small holes are formed at equal intervals on the side surface of the tip of the lance, and the tip of the lance is hermetically sealed. The high-pressure fluid is ejected in the lateral direction of the lance from each of the small holes at the tip of the lance.

Alternatively, in a lance attached to a high-pressure fluid jet gun of various high-pressure washers, a plurality of small holes are bored at equal intervals on the side surface of a short pipe having the same or substantially the same diameter as the lance to seal the tip. A lance / nozzle having a screw formed at the rear end is provided so that the lance / nozzle can be screwed to a screw formed at the tip of the lance. It is a solution to the problem.

[0012]

According to the present invention, a plurality of small holes are formed on the side surface at equal intervals, and a short tube whose both ends are sealed is fixed to the tip of the lance in a T-shaped communication state. With the T-shaped lance of a high-pressure washer,

Alternatively, a T-shaped lance is formed by fixing a short tube having a plurality of small holes at equal intervals on its side surface and sealing both ends to a tip of the short tube having a threaded rear end in a T-shaped communication state. The problem is solved by the T-shaped lance / nozzle of the high-pressure washing machine, which is provided with a dual-purpose nozzle and the T-shaped lance / nozzle is screwed to the screw at the tip of the lance of the high-pressure washing machine. is there.

[0014]

Embodiments of the present invention will now be described with reference to the drawings. (FIGS. 1 to 4) Lance 4 attached to a high pressure fluid jet gun 3 attached to a hose 3 of various high pressure washers 1.
In the lance 5 for narrow space cleaning of a high-pressure washing machine, a plurality of small holes 7 are formed at equal intervals on the side surface of the tip of the lance 4, and the tip of the lance 4 is sealed by a sealing lid 9. Yes,

Alternatively, in the lance 4 attached to the high pressure fluid injection gun 3 attached to the hose 3 of the various high pressure washer 1, a plurality of small holes 7 are formed on the side surface of the short pipe 10 having the same or substantially the same diameter as the lance 4. To form a lance / nozzle 5a having a screw 8a formed at the rear end thereof, the lance / nozzle 5a being screwed to the screw 8b formed at the tip of the lance 4. To prepare for
It is a lance and nozzle for cleaning narrow spaces of a high pressure washer.

[0016]

EXAMPLE As shown in FIGS. 5 to 7, a short tube 10 having a plurality of small holes 7 formed at equal intervals on the side surface and having both ends sealed by sealing lids 9 is formed into a T-shape at the tip of the lance 4. The T-shaped lance 6 of the high-pressure washing machine, which is fixedly provided in the communication state,

Alternatively, a short tube 11 having a plurality of small holes 7 formed on its side surface at equal intervals and sealed at both ends with sealing lids 9,
The T-shaped lance / nozzle 6a is provided by fixing the tip of the short pipe 10 having the screw 8a at the rear end to the T-shaped communication with the tip of the lance 4 of the high pressure cleaning machine 1. It is a T-shaped lance and nozzle of a high-pressure washer which is provided so as to be screwed onto the screw 8b.

[0018]

[Operations and effects] Since the narrow space cleaning lance 5 (narrow space cleaning lance and nozzle 5a) is formed to have the same or substantially the same diameter as the lance, it can be freely inserted into a narrow space where the lance can be inserted and operated for cleaning. Since it is possible to inject from a plurality of small holes toward the side (lateral direction) rather than toward the front of the lance as in the conventional case, a wide injection locus can be formed and a large area such as a radiator can be formed. The object can be cleaned very efficiently.

The cleaning of large objects such as fishing nets, glue nets, wire nets and lattices can be effectively used by the above-mentioned narrow space cleaning lance 5 (narrow space cleaning lance and nozzle 5a), but especially a T-shaped lance. The 6 (T-shaped lance / nozzle 6a) can form a wide injection trajectory toward the front of the lance, so that it is quite inefficient in the past, and a large space such as a fishing net, a glue net, a wire net, a lattice, etc. It is possible to clean various objects extremely efficiently.

It is possible to provide at a low cost because it does not require precision machining and forming unlike the conventional various nozzles and can be provided simply by forming small holes of a set diameter in a row in the pipe material of the lance.
