Abstract

The utility model relates to an air cleaner for engine, comprising an air inlet pipe, an air flue and a cavity connected between the air inlet pipe and the air flue; the utility model is characterized in that the cavity comprises two barrel-shaped filter cavities connected with each other by a channel; the filter cavity which is connected with the air flue is provided with a filter core; a cyclone cover which has a barrel-shaped structure and of which the outer wall is provided with helical fins is arranged between the filter core and the inner wall of the filter cavity. The utility model has the advantages of integrated appearance of the air filter, simple structure, convenient use and assembly, simple and short air filtering process, compact and reasonable structure, convenient maintenance and no block,.

Description

The conjuncted empty filter of two-chamber

Technical field

The utility model relates to the air-strainer that a kind of motor uses.

Technical background

Air-strainer is one of critical component that ensures the normal ride quality of motor, the quality of its filter makings amount is to the power of motor, direct influence is arranged working life etc., and used empty filter generally has the branch of one-level, secondary, three-stage filtration and coarse filtration, smart filter, and its structure is also divided multiple.Common product is simple in structure, has only suction tude, air flue and is connected filtering cavity between the two, and filtering cavity is generally tubular, interior dress filter core.This empty filter filter gas weak effect is subjected to cost impact especially for the empty filter of agricultural vehicle, and it is fair, again because work under bad environment, so can not guarantee the working life and the ride quality of motor.

Summary of the invention

The purpose of this utility model provides a kind of efficient filter makings amount and easy for installation, the conjuncted empty filter of the two-chamber that manufacture cost is moderate.

For achieving the above object, the utility model adopts following technological scheme:

The conjuncted empty filter of two-chamber described in the utility model comprise suction tude, air flue and be connected suction tude and air flue between cavity, it is characterized in that: described cavity comprises the filtering cavity by channel attached two tubulars.

Be provided with filter core in the filtering cavity that air flue is connected, be provided with the whirlwind cover between the inwall of filter core and filtering cavity, this whirlwind cover is a tubular structure, outer wall is provided with helical fin.

The design at first integrates the external form of empty filter, to adapt to purpose easy for installation, again coarse filtration and two processes of smart filter is made up, and forms coarse filtration, smart filter, and three processes of smart again filter are to guarantee to offer the air height cleaning of motor.Simple in structure, easy to install and use, and whole filter gas process is brief, fluent, because the compact structure of empty filter is reasonable, its maintaining is also very convenient.

Description of drawings

Fig. 1 is an an embodiment's of the present utility model structural representation;

Fig. 2 is the structural representation of whirlwind cover.

Embodiment

As shown in drawings, strainer 1 is a cap structure, and air enters in the strainer 1 by the fence hole that is provided with on the strainer and in the tracheae 3, thick thing by fence hole 2 every outside.Air enters the bottom of a secondary filter 4 through tracheae 3, heavier dirt sand falls into precipitated oil 10 the insides, gas continues to be inhaled into filter screen 6, and filter screen is two nets about in the of 6 minutes, and it is spacing by fan housing 5 to surf the Net, off linely held by fan housing holder 9, it fixedly is fastening by the wire clip 8 that is located at a secondary filter doffing, and the top cylinder of a secondary filter and doffing are also fastening by wire clip 8, and rubber seal 7 sealings are arranged in the middle of it, the purpose that wire clip 8 is set is to make things convenient for the filter cylinder dismounting, is convenient to maintaining.The place, close bottom surface of its doffing is provided with a splashproof circle 11, prevents that precipitated oil from splashing.Air enters the top of secondary filter 4 by filter screen 6, and enter in No. two secondary filters 13 by air flue 12, along revolving of whirlwind cover 17, form swirling eddy, the purpose that whirlwind cover 17 is set is to prevent that the oil gas that is inhaled into No. two filter cylinders once in a while from directly not spraying to filter core 16, but is rotated the air-flow band to barrel, descends along wall, air then enters in the filter core by filter core 16, enters engine intake by air flue 18 again.The filter cylinder up and down of No. two secondary filters, filter core and whirlwind cover all are by bolt 14 that is provided with and the fastening realization of nut.The following tube bottom of No. two secondary filters 13 is established a collection bag 15, be for making things convenient for dust discharge, reduce filter cylinder dismounting number of times and be provided with, No. one of whole empty filter assembly and No. two filter cylinders are connected into by passage 12 and by stiffening plate and are structure as a whole, and are installation and maintaining for convenience.The arrow indication is an air flow among the figure.

As shown in Figure 2, whirlwind cover 17 is a tubular structure, and outer wall is provided with helical fin 20.

Claims

1, the conjuncted empty filter of two-chamber, comprise suction tude (3), air flue (18) and be connected suction tude (3) and air flue (18) between cavity, it is characterized in that: described cavity comprises the filtering cavity of two tubulars that connected by passage (12).

2, the conjuncted empty filter of two-chamber according to claim 1, it is characterized in that: be provided with filter core (16) in the filtering cavity that air flue (18) is connected, be provided with whirlwind cover (17) between the inwall of filter core (16) and filtering cavity, this whirlwind cover (17) is a tubular structure, and outer wall is provided with helical fin (20).
