Abstract
The utility model discloses an air filtering device for a cab of a loading machine, and belongs to the technical field of engineering machines. The air filtering device comprises a connecting plate, an outer shell, an air door, a filtering screen, a fresh air opening and an air inlet. A sealed cavity is formed by a U-shaped side wall and an L-shaped side wall of the outer shell and the connecting plate. The fresh air opening is formed in the U-shaped side wall, and the fresh air opening 1 is communicated with the interior of the cab. The filtering screen is fixedly arranged to be tightly close to the inner side of the L-shaped side wall and the connecting plate. The air inlet is formed in the connecting plate below the filtering screen, and the air inlet is communicated with the exterior of the cab. The air door completely separating the fresh air opening and the air inlet is inserted into the upper end of the outer shell. The air door opens or closes a fresh air opening channel and an air inlet channel according to needs.

Description
Technical field
The utility model relates to technical field of engineering machinery, specifically a kind of loader cab air-filtering arrangement.
Background technology
Loader is worked conventionally under severe work condition environment, and muddy air will have a strong impact on the health of chaufeur in loader cab.Current air-filtering arrangement generally uses papery helical structure and oil bath depuration structure, and its filtering accuracy is high, and cost is higher; For common filtration, mainly use driving engine filtering form, generally adopt papery to filter and sponge filter structure, type of attachment is generally skeleton fixed type, and range of use is narrower, and often seal cavity cover body be there are certain requirements.Therefore in loader cab, conventionally there is no air-filtering arrangement, the health of chaufeur is on the hazard.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of loader cab air-filtering arrangement that facilitates installation and use.
The technical solution adopted in the utility model is: a kind of air intake filter, and it comprises connecting panel, shell, air door, filter screen, fresh wind port and ventilation inlet; Described shell forms seal chamber by U-shaped wall, L-type sidewall and connecting panel; On described U-shaped wall, offer fresh wind port, fresh wind port is communicated with operator's compartment inside; Near the fixing filter screen of L-type inside sidewalls and connecting panel place; On the connecting panel of described filter screen below, offer ventilation inlet, ventilation inlet is communicated with operator's compartment outside; In described shell upper end, insert the air door of separating fresh wind port and ventilation inlet completely.
It is further: described air door cross-sectional plane is cross, laminating and close the upper plane of U-shaped wall above the U-shaped wall of air door lower plane and shell; Described air door lower plane middle part is provided with the face of cylinder; Described U-shaped wall is provided with the face of cylinder and coordinates and arc groove.
The filter screen filler rod that described filter screen is L-type by cross-sectional plane is fixed, and filter screen filler rod one side is fixed on U-shaped wall, and filter screen filler rod another side compresses filter screen.
Described connecting panel is square, is respectively provided with a connecting bore at Qi Sijiao place.
Described fresh wind port is one to be welded on the cylindrical drum on U-shaped wall.
During use, connecting panel is fixed on bottom plate of driving cab or sidewall by connecting bore, fresh wind port is communicated with operator's compartment inside, ventilation inlet is communicated with operator's compartment outside, when fresh wind port need to suck filtering gas, take off air door, gas enters cavity from extraneous or muddy by ventilation inlet, after filtration after net filtration, then entered in requisite space by fresh wind port through cavity.
The beneficial effects of the utility model are: adopt simple mechanism, realize easily air filtering function, less demanding to seal cavity, easy to use, usability is strong, and cost is little, and maintaining is convenient.
