Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an asphalt emulsion dispersing device.

[Conventional technology]

When asphalt emulsion is sprayed onto roads, it is usually carried out using a spray vehicle equipped with a distributor or a small truck equipped with a spray bar having a number of nozzles arranged in series. This is very effective for spraying wide and long roads, but cannot be used for spraying narrow and short roads such as alleys and sidewalks.

Therefore, to spread asphalt emulsion in such narrow spaces, a small cart such as a cart is loaded with drums, oil cans, and a hand spray bar with a hose.
While pushing the cart around by hand, we spray locally with a hand spray bar.

[Problem that the invention attempts to solve]

Conventional methods of spraying in narrow spaces such as those described above do not allow uniform spraying, unlike spraying with a spray bar with many nozzles, and require a lot of labor. In short, there are problems such as extremely poor construction efficiency.

[Means for solving problems]

This invention uses a general-purpose engine and a human-powered mobile vehicle.
A pump and asphalt emulsion container are loaded, and a spray bar with many nozzles and a hand spray bar with a hose are installed, and the pump, spray bar, and hand spray bar are connected by a feed pipe. At the same time, an adjustment valve and one end of a bypass pipe are attached to this feed pipe, and the other end of this bypass pipe is connected to the pump, and the amount of emulsion discharged to the spray bar and the hand spreading bar is adjusted by the adjustment valve. , the excess amount is returned to the pump through a bypass pipe.

[Effect]

According to the present invention, when spraying an area about the width of a vehicle at once using a spray bar, first, open the handle of the spray bar, close the handle of the hand spraying hose, and move the vehicle to accommodate the spray. The asphalt emulsion in the container can be uniformly spread over a constant width. Next, when spraying in small areas, close the tip of the spray bar and open the tip of the hand spray bar, which makes it possible to spray effectively even in alleys and narrow corners. It will be possible.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

Fig. 1 is a plan view, Fig. 2 is a side view, and Fig. 3 is a front view. A pump for pumping the emulsion is driven by an engine 2, and a container 4, such as a drum or an oil can, contains the emulsion.

5 is a flexible hose, one end of which is connected to pump 3
The other end is inserted into the container 4.

6 is a spray bar with a valve 7 connected thereto, and 8 is a manual spray bar with a nozzle 9 attached to its tip.

Reference numeral 10 denotes a feed pipe connecting the pump 3, the spray bar 6, and the manual spray bar 8, and a regulating valve 11.
It serves as a branch to a bypass pipe 12 in order to adjust the amount of emulsion discharged to the spray bar 6 and the hand-spreading bar 8.

13 is a handle for the spray bar, 14 is a handle for a hand spraying hose, and 15 and 16 are nozzle handles. 17 is a scattering prevention cover.

According to the above configuration, first, when spraying about the width of the vehicle at once with the spray bar 6, the adjustment valve 1
Adjust the discharge amount by 1, close the pot 14,
By opening the pot 13, the emulsion in the container 4 can be sprayed all at once from each nozzle 7 of the spray bar 6 by the action of the pump 3, and the mobile vehicle 1 can be moved by a person. The spraying can be started and stopped using the nozzle kettle 15 on the handle of the mobile vehicle 1.

Next, when spraying is to be carried out in detail using the hand spraying hose 8, the spray bar can be sprayed by closing the tip 13 of the spray bar and opening the hand spraying tip 14.
Start and end operations are performed by .

[Effect of idea]

According to the present invention described in detail above, a general-purpose engine, a pump, and an asphalt emulsion container are loaded on a human-powered mobile vehicle, and a spray bar with a series of nozzles and a hose for manual spraying are further installed on the vehicle body. This spray bar allows you to evenly spread asphalt emulsion over a relatively wide area such as a sidewalk, while the manual spray bar allows you to properly spray asphalt emulsion in narrow or complex areas. This means that an asphalt film with a good finish can be formed on the surface.

Further, the pump is connected to the spray bar and the hand spraying bar through a feed pipe, an adjustment valve and a bypass pipe are attached to one end of the feed pipe, and the other end of the bypass pipe is connected to the pump; By adjusting the amount of emulsion discharged to the spray bar and hand spreading bar using the above adjustment valve, and returning the excess amount to the pump via the bypass pipe, cans such as oil cans are generally There is only a port, and if that port is used as a discharge port, there is no return port and the excess cannot be stored, making it impossible to adjust the discharge amount. However, by using a bypass pipe to return the fluid to the pump. , the amount of emulsion discharged from the spray bar and the hand-spreading bar can be arbitrarily adjusted, and has the effect of always being able to spray an appropriate amount.

Further, since the device is small and easy to disassemble and assemble, it can be transported by a small truck or the like, making it a highly mobile asphalt emulsion dispersing device.
