Description

Dry sweeper

The present invention relates to a dry road cleaning vehicle, and more particularly to a dry road cleaning vehicle equipped with a dry filter that is easy to clean.

In general, each local government or an institution managing roads maintains and maintains the road surface in a clean state by periodically removing foreign substances and fine dust accumulated on the road surface for roads that are already built and used.

In particular, the disposal of waste is very important in relation to the aesthetics of the city, and cleaning of roads and roads is particularly important due to the characteristics of the city where a high population is concentrated.

Accordingly, a road cleaning vehicle that sucks and cleans foreign substances on the road surface is used so that the maintenance / management of the road surface is not difficult even with a small manpower.

The road cleaning vehicle sucks foreign matters on the road, filters air polluted by the sucked foreign matters, and discharges them into the atmosphere.

Therefore, it is important for the road cleaning car to clean the air polluted by foreign substances on the road surface and to discharge it back to the atmosphere, and various efforts are being made for this.

However, the conventional road cleaning vehicle has the following problems.

First, the road cleaning vehicle according to the related art is loaded with a foreign material on the road through the suction part and loaded into the loading box, and then the suction part or the discharge part to minimize the generation of dust when the air containing the fine dust is discharged to the outside through the discharge part. By spraying water on the water, as well as waste, there is a problem that the amount of waste that can be actually collected as the water is loaded into the load.

Second, since the filter is installed inside the loading box in which foreign matters on the road surface of the road cleaning vehicle are introduced and loaded, it is not easy for the operator to separate the filter for the replacement and cleaning of the filter.

Third, the conventional road cleaning vehicle is provided with a loading box in which foreign substances on the road surface are introduced and loaded, and when a filter for filtering foreign substances from the air is used for a long time and contaminated by foreign substances, the worker must manually shake off the foreign substances from the filter. There was a ham.

Fourth, the conventional road cleaning vehicle is provided with a loading box in which foreign matters on the road surface are loaded and loaded thereon, so that the filter area of the filter that filters foreign matters from the air is small, so that the filter has to be cleaned or replaced even after a short time of use.

In order to solve the above problems, the present invention is to provide a dry road cleaning vehicle equipped with a dry filter easy to clean.

In order to achieve the above technical problem, the present invention is a loading unit that is accommodated by the foreign matter on the road surface by the suction force; A discharge duct through which the air introduced into the stack is discharged; A connecting housing installed at the loading part and connecting the loading part and the discharge duct; At least one side of the connection housing is installed inward of the loading unit so that foreign matters are filtered out before the air contained in the loading unit is moved to the connection housing, and the filtered air is transferred inside the connection housing. A filter member having a flow path portion communicating with the connection housing, coupled to both sides of the filter member to fix the filter member, and at least one cover having a through hole corresponding to the flow path portion; Filtration device is provided in the cover is formed to correspond to the through-hole and the flow path portion and the outer peripheral surface is formed with a first coupling portion is connected to the second adapter coupled to the second coupling portion detachably connected to the housing housing ; And in order to shake off the foreign matter adhering to the filtration device, the air is stored by the power generated by the power unit is filled with high pressure and the air filling unit, connected to the air filling unit to guide the transfer of air, but the transfer High pressure that is formed in a single tube to form a flow path of the air and is formed so that the portion provided inside the connection housing through the connection housing is located to correspond to the upper side of the flow path, and is injected from the injection hole An air supply unit for allowing air to flow into the flow path unit, and an air supply unit installed at a portion where air ejected from the air filling unit is introduced into the air supply unit to selectively supply air to the air supply unit Dry road cleaning vehicle comprising a debris removal device including a valve Provided.
