Abstract

The utility model relates to an air filter of a bulldozer, which is provided with a strip-shaped shell main body with openings at two ends and the upper part. A front end cover is buckled on the front end of the shell main body, wherein a plurality of prefilter pipes are arranged on the front end face of the front end cover, and the lower end of the front end cover is provided with a dedusting valve. A rear end cover with an air outlet is buckled at the rear end of the shell main body. An upper cover is buckled on the upper opening of the shell main body and is provided with a buckle which can be buckled on a hanger at the side of the shell main body. The joint of shell main body with the front end cover, the rear end cover and the upper cover is sealed. The shell main body is internally provided with a main filter element at the front and a safety filter element at the back, wherein the peripheral surfaces of the main filter element and the safety element are matched with a peripheral surface enclosed by the shell main body and the upper cover in a sealing mode. The utility model has the characteristics of high filtering efficiency, high reliability, concise appearance, convenient installation and lower cost.

Description

The empty filter of bulldozer

Technical field:

The utility model relates to a kind of air-strainer, the empty filter of especially a kind of bulldozer.

Background technique:

The air intake filter of existing bulldozer motor generally is that empty filter assembly is positioned at hood inside by prefilter assembly and empty filter assembly conventional construction dimerous, and the prefilter assembly is positioned at the hood outside, and the two connects by transition apparatus.There is following shortcoming in this conventional construction: the layout of (1) motor, hood and transition apparatus, design all need fully to consider and take into account the installation of sky filter and prefilter, increase manufacture cost, and the project that increases also is potential problem hidden danger; (2) owing to of the variation of different motors to the air inlet demand, cause coupling, the Connecting format numerous and complicated of sky filter, prefilter, be not easy to make product percent of pass, standardization; (3) prefilter is exposed to the hood outside, for the complicated abominable bulldozer of operation operating mode, can increase the risk of engine aspirating system on the one hand, clumsy on the other hand prefilter also can block the original just very limited field of front vision of driver, and this problem is especially outstanding concerning the middle low power bulldozer; (4) mounting type of prefilter existing problems hidden danger: the mounting type of traditional prefilter generally has two kinds: directly be installed on the sky filter suction port or by transition apparatus by clip and be fixed on the hood, all be difficult to avoid existing leak between prefilter and the empty filter, and under the oscillating action that bulldozer produces, this leak there is a strong possibility property can constantly enlarge, make dust enter the sky filter, thereby cause the increase of empty filter maintenance cost or form potential faults without pre-flock.This in addition mounting type must be had higher requirement to the casing rigidity of empty filter, prefilter, and this has also increased the complete machine cost; (5) traditional empty filter is owing to will reserve helical duct for charge air flow, not only make the profile of sky filter be subject to cylindrical, and increased the external diameter of empty filter greatly, middle low power bulldozer for compact structure, the problem of insufficient space just highlights in the hood, and the layout of empty filter is comparatively difficult.

Summary of the invention:

The purpose of this utility model provides the empty filter of a kind of bulldozer, for the use of middle low power bulldozer motor, solve that traditional inlet air filtration system effectiveness is on the low side, poor reliability, influence outward appearance, block the visual field, realistic problem such as installation and maintenance are loaded down with trivial details.

The purpose of this utility model realizes as follows: it comprises prefilter and empty filter, the strip housing body that two ends and upper opening are arranged, housing body also is a fitting seat, the front end of housing body is buckled with front-end face and arranges some pre-flock organ pipes, the lower end has the front cover of dust discharge valve, the rear end of housing body is buckled with the rear end cover of taking gas port out of, the loam cake that is buckled with suitable for reading of housing body, on cover the buckle that can be buckled in housing body side hangers be set, housing body and front cover, rear end cover, the sealing of loam cake junction, be equipped with in the housing body main the preceding filter core and after safe filter core, the side face that the outer circumferential face of main filter core and safe filter core and housing body and loam cake surround is sealed and matched.

The beneficial effects of the utility model are: (1) filtration efficiency: adopt novel, strip filter material, air-flow no longer is a helical, but axial straight-through type air-flow, resistance is littler; (2) high reliability: prefilter, empty filter become one, and housing adopts the novel earthquake-proof design, and weight is lighter, no longer adopt traditional axial seal mode between filter core and the housing, but adopt more simple and reliable radial seal, and sealing progression is more, and the component that relate to reduce by half; (3) outward appearance is succinct: the empty filter compact appearance after the improvement, place hood inside with integrated prefilter, and increased the driver visual field, improved the machine operation performance, and machine shape is more succinct attractive in appearance; (4) easy for installation: empty filter self is integrated fitting seat, and be distributed on each face except that the renew cartridge side, make mounting type more flexible.Filter core adopts snap fit on housing, safeguards convenient; (5) cost is lower: reduced number of spare parts, reduced the machine manufacture cost; Empty filter is arranged in hood inside, and air inlet is more cleaned, and has reduced machine working service cost.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model.

Embodiment:

With reference to accompanying drawing, the strip housing body 6 that two ends and upper opening are arranged, the front end of housing body 6 is buckled with front-end face and arranges some pre-flock organ pipes, the lower end has the front cover 8 of dust discharge valve 7, the rear end of housing body 6 is buckled with the rear end cover 4 of taking gas port 3 out of, the loam cake 5 that has handle 1 that is buckled with suitable for reading of housing body 6, the buckle 2 that can be buckled in housing body 6 side hangers is set on the loam cake 5, housing body 6 and front cover 8, rear end cover 4, the sealing of loam cake 5 junctions, be equipped with in the housing body 6 main the preceding filter core and after safe filter core, the side face that the outer circumferential face of main filter core and safe filter core and housing body 6 and loam cake 5 surround is sealed and matched, with prefilter, empty filter becomes one.
