Abstract
The utility model discloses a kind of agricultural machinery high efficiency filter prefilter assembly, including housing, filtering cabin, dust removing tube, dust stratification cup, shading rain cap and escape pipe, it is characterized in that, the upper end of the housing is provided with filtering cabin by intermediate bin, filter screen is installed in the filtering cabin, shading rain cap is installed at the top of the filtering cabin, the bottom of the housing is provided with dust removing tube by locking device, blade ring is installed between the housing and dust removing tube, the outside of the blade ring is located at hull outside and is provided with escape pipe, and the dust stratification cup is arranged on the bottom of dust removing tube.The utility model uses filter screen and blade ring double medium filtration, and coarse filtration efficiency is improved by dust removing tube；The utility model maintaining is convenient, and using dust removing tube and laying dust cup, the dust of filtering accumulates in easy maintenance in laying dust cup, and good using effect is obtained during actual entrucking use.
Description
Technical field
It the utility model is related to farm machinery parts field, and in particular to a kind of agricultural machinery high efficiency filter prefilter assembly.
Background technology
At present, subject matter existing for existing agricultural equipment gas handling system prefilter is：Prefilter coarse filtration efficiency is low, causes
Cleaner cartridge cleaner short life, maintenance period is short, and consumer's cost is high.And prefilter dust discharge effect is poor and is not easy to maintain, and causes
Coarse filtration efficiency is low, and in the market engineering machinery prefilter is mainly by following several：
（1）The cup type prefilter of laying dust：Prefilter is assembled into by through type blade ring and laying dust cup, air filter passes through blade
Ring filters, and the dust filtered out accumulates into laying dust cup；This prefilter filter efficiency is low, and is not easy after being filled with ash in laying dust cup
Maintenance.
（2）Injection dust-exhausting prefilter：Prefilter can cause the increase of silencer exhaust back pressure using injection dust discharge, and exhaust is made an uproar
Sound raises, and engine power reduces.Air blow back phenomenon easily occurs for prefilter injection dust discharge simultaneously, and such coarse filtration reduces, pre-flock
Device is damaged.
（3）Straight-through cyclone tube type prefilter, utilizes tangential dust discharge：Install fan additional on prefilter, increase prefilter is tangential
Flow velocity, dust is set to be discharged at dust-exhausting port, but the prefilter of this structure can not realize this dust discharge effect on the market.Dust can not be arranged
Go out, cause prefilter coarse filtration extremely low, the dust gone out is directly entered inside air filter again.
The content of the invention
The purpose of this utility model is to provide a kind of agricultural machinery high efficiency filter prefilter assembly.
To achieve the above object, the technical solution adopted in the utility model is：A kind of agricultural machinery is total with high efficiency filter prefilter
Into, including housing, filtering cabin, dust removing tube, dust stratification cup, shading rain cap and escape pipe, the upper end of the housing installed by intermediate bin
There is filtering cabin, filter screen is installed in the filtering cabin, shading rain cap is installed at the top of the filtering cabin, the bottom of the housing leads to
Cross locking device and dust removing tube is installed, blade ring is installed, the outside of the blade ring is located between the housing and dust removing tube
Hull outside is provided with escape pipe, and the dust stratification cup is arranged on the bottom of dust removing tube.
By adopting the above-described technical solution, the utility model has the advantages that：The utility model uses filter screen
With blade ring double medium filtration, coarse filtration efficiency is improved by dust removing tube；The utility model maintaining is convenient, uses dust removing tube and product
Dirt cup, the dust of filtering accumulate in easy maintenance in laying dust cup, are obtained during actual entrucking use well using effect
Fruit.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
In figure：1st, housing, 2, filtering cabin, 3, dust removing tube, 4, dust stratification cup, 5, shading rain cap, 6, escape pipe, 7, intermediate bin, 8,
Filter screen, 9, locking device, 10, blade ring.
Embodiment
As shown in figure 1, the technical solution adopted in the utility model is：A kind of agricultural machinery high efficiency filter prefilter assembly, bag
Housing 1, filtering cabin 2, dust removing tube 3, dust stratification cup 4, shading rain cap 5 and escape pipe 6 are included, the upper end of the housing 1 is pacified by intermediate bin 7
Equipped with filtering cabin 2, filter screen 8 is installed in the filtering cabin 2, the top of the filtering cabin 2 is provided with shading rain cap 5, the housing 1
Bottom dust removing tube 3 is provided with by locking device 9, blade ring 10, the leaf are installed between the housing 1 and dust removing tube 3
The outside of loop 10 is located at the outside of housing 1 and is provided with escape pipe 6, and the dust stratification cup 4 is arranged on the bottom of dust removing tube 3.
By arrangement above, operation principle of the present utility model is as follows：The utility model is made up of filter screen 8 and blade ring 10
Double medium filtration, the air with dust first passes through the filter screen 8 in filtering cabin 2, enters housing 1 after preliminary filtering, downwards process
The dust in air is produced centrifugal force during blade ring 10, make dust along dust removing tube 3 downwardly into laying dust cup 4, and filtered
Air entered by escape pipe 6 inside air filter.
Above content is to combine the detailed description that specific preferred embodiment is made to the utility model, it is impossible to assert this
The embodiment of utility model is confined to these explanations.For the ordinary skill people of the utility model art
For member, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should be all considered as
Belong to the scope of patent protection that claims that the utility model is submitted determine.
