The cyclone air cleaner is arranged on an engine air inlet and communicates with an engine air inflow tube, a flow guide sleeve is arranged at the end of the cyclone air cleaner, and dust collecting cups are arranged on the inner circumferential side of the cyclone air cleaner. A paper filter element is arranged on the position, connected with the air flow tube, of the middle position of the cyclone air cleaner, and after air passes through the flow guide sleeve, dust is separated in a rotation mode, the air passes through the paper filter element, and the air enters the air inflow tube. The engine air inflow filter device further comprises a throat tube and a dust discharging tube, the throat tube is connected with an engine air discharging tube, and the periphery of the engine air discharging tube is hermetically sleeved with one end of the throat tube. One end of the throat tube communicates with the engine air discharging tube, the dust discharging tube is arranged on the outer side of the cyclone air cleaner, and one end of the dust discharging tube communicates with the dust collecting cups. The other end of the dust discharging tube is connected with the end, arranged on the periphery of the engine air discharging tube in a sleeving mode, of the throat tube. According to the engine air inflow filter device, the dust can be effectively and timely removed.
Description
Technical field
The present invention relates to a kind of air filter for harvester.
Background technology
The air filter of part harvester adopts cyclone air cleaner.The plastics of this cleaner paper filter element end
Cover is kuppe, and the blade on cover makes air rotate, and 80% dust separates under the influence of centrifugal force, is collected in dust in bosom,
The dust reaching paper filter element is suck amount of dust 20%.
When precipitating full dust in dust pocket, all dusts can only rely on paper filter element to filter, and paper filter element is blocked up by dust
After death air inflow will be had a strong impact on, thus lead to engine internal combustion oil firing not exclusively, engine power reduces, engine is subject to
Damage, harvester operation speed declines, the drum threshing not adverse consequences such as net, straw chopping effect difference.
Content of the invention
The invention aims to defect present in solution prior art, provide one kind can remove ash effectively, in time
The air-intaking filter of engine of dirt.
In order to achieve the above object, the invention provides a kind of air-intaking filter of engine, including cyclone-type air air filter
Clear device；Air filter, at engine intake, is connected with engine air inlet tube；Air filter end is provided with water conservancy diversion
Cover, internal the week side of boss is provided with dust pocket, and middle part and air inlet pipe connecting place are provided with paper filter element；After kuppe, rotating separation goes out air
After dust, then enter air inlet pipe after paper filter element；Inventive engine air intake filter also includes trunnion and dust discharging tube；
Trunnion is connected with the exhaust pipe of engine；The sealing of trunnion one end is placed on exhaust pipe of engine periphery, and is connected with the exhaust pipe of engine
Logical；Dust discharging tube is outside cyclone air cleaner, and one end is connected with dust pocket, and the other end and trunnion are placed on to be sent out
One end of motivation blast pipe periphery is connected.
Wherein, the internal diameter in the middle part of trunnion is identical with the internal diameter of the exhaust pipe of engine.
Dust discharging tube is connected with the bottom of dust pocket.
Inventive engine air intake filter also includes negative tube；Negative tube is placed on outside the exhaust pipe of engine located at trunnion
The one end in week, and be connected with trunnion；Dust discharging tube is connected with negative tube by steel wire tube.
The present invention has advantages below compared to existing technology：The present invention utilizes the negative pressure that trunnion produces, by dust from dust
Suction out in cup, and power is directly produced by the flowing of waste gas in the exhaust pipe of engine, need not in addition provide, efficient, green, ring
Protect.Inventive engine air intake filter structure is simple, can from dedusting, can not only effective protection engine, acceptable
Save driver's daily working time, improve harvester harvesting quality.

Specific embodiment
The present invention is described in detail below in conjunction with the accompanying drawings.
As shown in figure 1, inventive engine air intake filter includes air filter 1, trunnion 3, negative tube 6, steel wire
Pipe 7 and dust discharging tube 2.In conjunction with Fig. 3, air filter 1 adopts cyclone air cleaner, and end is provided with kuppe 11, interior
Portion's the week side of boss is provided with dust pocket 12, and inside center and engine air inlet tube 5 junction are provided with paper filter element 13.Air through kuppe 11,
After rotating separation goes out dust, the dust in outside enters in dust pocket 12, and middle air enters engine after paper filter element 13 and enters
In tracheae 5.The bottom of dust pocket 12 is provided with dust export, is connected with the dust discharging tube 2 of the outside setting of air filter 1.
As shown in Fig. 2 trunnion 3 is the gas backflow device that centre is little, two is big.The internal diameter of E and engine in the middle part of trunnion
The internal diameter of blast pipe 4 is identical, bigger than the diameter of the exhaust pipe of engine 4 one centimetre of two ends horn mouth diameter, wherein one closing set
In the outside of the exhaust pipe of engine 4, and this outside is provided with negative tube 6.In conjunction with Fig. 1, dust pocket 12 passes sequentially through dust and discharges
Pipe 2, steel wire tube 7, negative tube 6 are connected with trunnion 3.
