Description
Technical field
The utility model belongs to agricultural mechanical field, and in particular to a kind of combine harvester inlet duct.
Background technique
Combine harvester operation link is severe, is not only rice and kernel shell, and as well as dust such as sandy soil, and engine is to air
Cleannes it is more demanding, therefore air intake filter is essential.And air filter operation is bad, will cause engine
Operating is unstable, abnormal vibrations occurs, side by side black smoke, and knock occurs in when low speed, and anxious knock when accelerating aggravates, and when high speed taps
Sound weakens or disappears, and it is rough that this phenomenon is referred to as engine operation.
The main reason for causing deficiency of air is caused by air filter blocking.Air into engine must be first
After first passing through air filter filtering, cylinder just can enter.Air, the especially sky of engine sucking are needed when fuel combustion
Gas is applied not only to burn, while the high temperature that when engine is using compressed air generates makes oil plant ignition work done.Therefore, sucking is empty
Gas lazy weight has dual adverse effect.Engine element is famous with thermal efficiency height, if row's black smoke, not only reduces hair
The thermal effect of motivation, and will increase oil consumption, while increasing exhaust pollution.
The air filter that combine harvester uses at present generally has following methods:
1, dried mushroom head is increased, i.e. increasing blast pipe.
Unpressurized combine harvester of this mode less than 100 horsepowers has certain effect, more than or equal to 100 horsepowers
With lower than 100 horsepowers but pressurization engine effect it is inadequate, because of such engine charge excessive velocities, Desert Storm from
Mental and physical efforts resist the air-intake negative-pressure suction of only engine, so effect is unobvious.
2, double filter cores, which refuel, filters.
Although reducing harm of the external booty to gas handling system, the clearing times of filter core are not can be reduced, to improve
Operating efficiency, though the resistance for increasing air inlet reduces the power of engine.
3, double air cleaners in parallel
Benefit is reduction of the intake resistance of engine, increases air inflow, increases the power of engine indirectly, lacks
Point is cost and the time for increasing maintenance, it is proposed that select it is such change method must select superior filter case and air inlet
Sebific duct, otherwise more air inlets also increase the risk of a scuffing of cylinder bore with regard to more a gas leakage probabilities, operate to driver
Degree claims.
4, splicing is filtered after oily filter
For this method due to being used as safety effect using paper filter, filter effect is preferable, and paper filter can also be complete in daily harvesting task
At Shi Genghuan, but the resistance of oily filter is larger, and feed rate is smaller, and larger specification oily filter, cost will be selected by making up air inflow defect
It is higher.
The above usual manner, it is difficult in the case where reducing filter core clearing times, improving stability, improve filter effect.
Utility model content
The technical problems to be solved in the utility model is maintenance existing for above-mentioned classical joint harvester inlet duct
The not high problem of cumbersome, intake efficiency.
The utility model specifically adopts the technical scheme that a kind of combine harvester inlet duct, including shield, ring
Streaming cyclone separator, wet-type cleaner and connecting tube,
Shield includes cover board and filter chamber, and cover board is removably mounted on above filter chamber by bindiny mechanism, and is covered
There are gap between plate and filter chamber, cover board is taper, has cyclic annular air inlet on the outside of cover board, thus combine harvester inlet duct
Airintake direction be from bottom to top that the sundries for reducing freely falling body enters device, and filter chamber is tubular, be equipped in filter chamber thick
Filter filter core；
The air inlet of circulation whirlwind separator and the filter chamber of shield are exported and are connected, circulation whirlwind separator bottom
It is provided with dust pocket, dust pocket periodic cleaning；It is filtered by the first connecting tube and wet type air circulation whirlwind separator gas outlet
Clear device connection；
Wet-type cleaner includes discharge outlet, and the impurity such as greasy dirt, dust are cleared up, and wet-type cleaner passes through second
Connecting tube accesses air intake branch of the engine.
Further, it in order to reduce the larger particles such as crushing straw, rhizome, grogs, insect, is set between cover board and filter chamber
It is equipped with gauze.
Further, in order to guarantee air inflow, coarse filtration filter core uses terylene filter cloth, and mesh number is 20-40.
Further, shield, circulation whirlwind separator, wet-type cleaner are installed in combine harvester driving
Room side wall.
Further, wet-type cleaner uses oil immersed type, and material for core is wire cloth.
Further, the first connecting tube, the second connecting tube use wire braided hose.
Combine harvester inlet duct principle described in the utility model are as follows:
It is filtered using level Four, the first step, first passes through gauze the filtering crushing straw, rhizome, grogs, insect in shield；The
It is two, smaller by mesh number, fall larger particles through the biggish coarse filtration filter element filtering of partial size；Third step passes through circulation whirlwind
Separator filters out most of above dusts and alleviates subsequent air filter since circulation whirlwind separator maintenance requirement is low
The load of clear device；4th, by the oily filter of air cleaner, by the subtle pollutant removal in air.
It has the beneficial effect that
1, the method avoids filtering using paper, greatly reduces the intake resistance of engine, increases air inflow, improves
The power of engine；
2, the dust particle in field is removed by circulation whirlwind separator, high dust collection efficiency, maintenance is simple, and mitigates
The filter pressure of air cleaner prevents larger particles from entering air cleaner, increases air cleaner service life；
3, add the shield with gauze before circulation whirlwind separator, biggish stalk is avoided to enter.
