Description

[Detailed description of the invention] The present invention relates to a dust suction device for sucking dust on the ground through a nozzle opening provided at the tip of a suction pipe using the wind power of a fan and collecting the dust in a dust collection container. It is something.

Conventionally, in vacuum cleaners mainly used for indoor cleaning, a removable nozzle 3 is fitted and fixed to the tip of an air intake pipe 1, as shown in Fig. 3, in order to clean the inside of the rail groove of a door roller. , this nozzle 3
A narrow scraper 7 protruding forward is integrally formed at the lower edge of the opening 5, and this scraper 7 scrapes off dust adhering to the rail groove and sucks it from the opening 5. It was hot. This scraper with the lower edge of the nozzle protruding forward is attached to a dust suction device that sucks up fallen leaves scattered on the ground outdoors and collects them in a dust container. It can be used effectively on hard ground such as paved roads when scraping and suctioning, but on soft ground or grass etc.
Since this scraper had to be pushed diagonally downward relative to the ground, the tip of the scraper dug into the ground, making it impossible to use it as a scraper. As a countermeasure against this problem, a scraper with a flat front edge bent downward, or a scraper with a bent front edge bent downward and both side edges bent downward, can be used to remove fallen leaves that have adhered to the ground. There is a method that scrapes off debris such as fallen leaves, but this method uses a force that pulls the scraper diagonally upward, so it will not dig into the ground even if it is soft, but it will scrape up dust such as fallen leaves from the lawn. In some cases, the front edge of the scraper cannot be used to clean the lawn because the front edge slides over the pulled-down lawn grass leaves and cannot scrape up the fallen leaves and other dust that accumulates at the base of the grass roots. Nakatsuta.

In this invention, the nozzle opening is horizontally flat, and the nozzle opening is equipped with a rake-like scraper in which a plurality of scraping rods with the front end bent downward are arranged in parallel at appropriate intervals. This scraper is removably fixed and is used by attaching it to the opening when necessary for cleaning the lawn, etc. It allows you to easily scrape up the base of the grass roots of the lawn, and the nozzle opening Since the part is formed horizontally and flatly, it is possible to scrape and suction uniformly over a wide range, and the flow of suction air passes between the scraping rods and bends toward the opening. The purpose of the present invention is to provide a dust suction device that can powerfully and easily suck up fallen leaves and the like because the dust flows in a straight line.

Hereinafter, one embodiment of this invention will be described in detail using the drawings.

In FIGS. 1 and 2, reference numeral 9 denotes a portable dust suction device, which is constructed as follows. That is,
Reference numeral 11 denotes a main body case that houses an engine (not shown) and a blower fan (not shown), 13 a handle provided on the upper part of the main case 11, and 13 a blower pipe that blows pressurized air generated by the blower fan. It is. Reference numeral 17 denotes a dust collector detachably attached to the tip of the blower pipe 15, and is constructed as follows.
That is, 19 is a confluence pipe that fits into the tip of the blower pipe 15, and the dust suction passage 27 that obliquely flows into the blower passage 25 provided between the inlet 21 and the outlet 23 is oriented in the direction of the outlet 23. They are merging together. Reference numeral 29 denotes an air suction pipe that fits into the tip of the dust suction passage 27, and a nozzle 31 is fixedly connected to the tip. The nozzle 31 is constructed as follows. That is, as shown in Fig. 2, it is formed in a triangular shape when viewed from above,
A wide opening 33 is opened at the tip. A scraper 37 having a scraping rod 35 is mounted on the upper side of the opening 33 of the nozzle 31.
It is detachably attached to the nozzle 31.

The base 39 of the scraper 37 is provided with a plurality of mounting holes 41 for fixing the scraper 37 to the nozzle 31. Match the mounting screw holes 43 and attach the scraper 37 to the nozzle 3 using the mounting screws 45.
1 shall be tightened and fixed. The raking rod 35 is formed by bending the tip downward, and extends the base 3 at appropriate intervals.
They are placed side by side, one in every nine. A bag-shaped dust container 47 is suspended below the blast pipe 15 by a fixture 49, and an opening 51 fits into the outlet 23.

When performing dust collection work using the dust suction device configured in this way, the worker holds the handle 13 with one hand and the blow pipe 15 with the other hand, and moves the scraping rod 35 of the scraper 37 to the ground surface. When the ground surface is brought into contact with the surface of the ground, the dust adhering to the ground surface is removed by the scraper 37. In particular, when cleaning the lawn, the raking rod 35 can easily scrape out dust from the base of the grass roots.
Pressure air generated by a blower fan (not shown) passes through the blower pipe 15, the air passage 25 from the inlet 21 of the confluence pipe 19 at high speed, enters the dust container 47 from the outlet 23, and enters the dust container 47 through the cloth grain. and is released into the atmosphere. When the air passes through the air passage 25 at high speed,
The air in the dust suction path 27 is drawn in and creates negative pressure,
Air is sucked in through the opening 33 of the nozzle 31. This suction air sucks dust on the ground surface and
9, passes through the dust suction path 27, merges with the air in the ventilation path 25, enters the dust container 43, and is collected.

In this embodiment, dust is sucked through the air suction pipe by using the suction air generated when the air from the blower fan passes through the junction pipe, but dust may also be sucked through the air suction pipe by directly using the suction air generated by the fan.

Further, the main body case 11 described above may be attached with a conveyance device such as wheels or a sled so that the main body case 11 can be moved easily, or a rope with a handle may be attached to the main body case 11. The case may be moved remotely.

In addition, the above-mentioned air suction pipe 29 is provided as a flexible pipe that can maintain any curved position and telescopic position, and by making this flexible pipe long, the operator can cover a wide range without carrying the main body case. It may also be possible to perform cleaning work.

Since the present invention has the configuration described in the claims for utility model registration, it is possible to collect and clean dust stuck to the ground surface or dust such as fallen leaves entangled in grass, etc., and has a great cleaning effect. .

In particular, when cleaning the lawn, it is possible to easily scrape out and suck up dust such as fallen leaves that have accumulated at the base of the grass roots. The wind is sucked in a straight line, making it easy to suck in dust, and furthermore, the dust can be sucked uniformly and efficiently over a wide range.

It should be noted that this invention is not limited to the above-mentioned embodiments, and can be implemented in modes other than the above-mentioned embodiments.

Furthermore, although reference numerals are written in the claims section of the utility model registration for convenience of comparison with the drawings, the reference numerals do not limit the technical scope of this invention.
