Abstract
The utility model discloses an engine device and a combine harvester using the engine device. The engine device comprises an engine device body and an air filter communicated with an air inlet of the engine device main body; an air outlet of the engine main body is provided with an air exhaust pipe; the air filter is provided with a dust extraction port; a dust extraction pipe is arranged between the air exhaust pipe and the air filter; and one end of the dust extraction pipe is communicated with the dust extraction port while the other end of the dust extraction pipe is communicated with the air exhaust pipe on the air outlet near the engine. When the engine device main body works, the engine device body can exhaust lots of CO2 and CO from the air exhaust pipe, so that the pressure in the air exhaust pipe is lower than that in the air filter, and a pressure difference is resulted between the air filter and the air exhaust pipe, which creates conditions for the air filter to extract dust inside. As long as the engine device body works, the dust in the air filter can be extracted immediately.
Description
Technical field
The utility model relates to a kind of grain combine, is specifically related to the engine device of grain combine.
Background technique
The motor of grain harvester combine is in the work engineering, and needing air-strainer is that it provides clean air, existing air-strainer; As shown in Figure 1; Comprise housing 101, be provided with filter core in the housing 101, housing 101 is provided with suction port 102, relief opening 103 and dedusting mouth 105; The relief opening 103 of air-strainer is communicated with the suction port of motor through pneumatic tube 104, and dedusting mouth 105 places are provided with dedusting duckbilled 106.During work, air is got in the housing 101 by the suction port 102 of air-strainer, and the cleaned air that process is filtered is got in the motors through pneumatic tube 104 by the relief opening 103 of air-strainer; And the dust of formation such as suspended particulate is stayed in the housing 101 in the air; Have only that the housing 101 of air-strainer is inside and outside must to reach certain pressure reduction, dedusting duckbilled 106 is opened just and can be opened, and dust is able to get rid of; Dedusting mouth 105 was closed at once when inside and outside differential pressure was not enough, smoothly dedusting.Because housing reaches certain pressure reduction and needs certain hour, so dust can not well discharge, and this just causes the air-strainer easy blocking; Thereby cause engine high-temperature; This needs the user to check often, in time clears up the filter core and the housing of air-strainer, brings inconvenience to the user.
The model utility content
The purpose of the utility model provides a kind of air-strainer that when engine body is worked, can guarantee and continues the engine device of dust discharge, and the combine-harvester that uses this motor is provided simultaneously.
The engine device of the utility model adopts following technological scheme: a kind of engine device; Comprise engine body and the air-strainer that is communicated with the suction port of engine body; The exhaust ports of said engine body is provided with outlet pipe; Said air-strainer has the dedusting mouth, is provided with dust removing tube between said outlet pipe and the air-strainer, and an end of dust removing tube is communicated with said dedusting mouth, the other end is being communicated with said outlet pipe near the exhaust opening of engine place.
Be serially connected with silencing apparatus on the said outlet pipe, said dust removing tube is communicated with said outlet pipe through silencing apparatus, and said dust removing tube is communicated with the silencing apparatus outer wall.
The combine-harvester of the utility model adopts following technological scheme: a kind of combine-harvester; Comprise engine device; Said engine device comprises engine body and the air-strainer that is communicated with the suction port of engine body; The exhaust ports of said engine body is provided with outlet pipe; Said air-strainer has the dedusting mouth, it is characterized in that: be provided with dust removing tube between said outlet pipe and the air-strainer, an end of dust removing tube is communicated with said dedusting mouth, the other end is being communicated with said outlet pipe near the exhaust opening of engine place.
Be serially connected with silencing apparatus on the said outlet pipe, said dust removing tube is communicated with said outlet pipe through silencing apparatus, and said dust removing tube is communicated with the silencing apparatus outer wall.
Adopt the engine device of said structure and use the combine-harvester of this engine device; Because the dedusting mouth of air-strainer is communicated with the outlet pipe of engine body through dust removing tube; And the end that links to each other with outlet pipe of dust removing tube goes out near the relief opening of engine body; When engine body was worked, engine body was with a large amount of CO
2Discharge from outlet pipe with CO; Cause the pressure in the outlet pipe to be lower than the pressure in the air-strainer, make air-strainer and outlet pipe have pressure reduction, discharge the condition of having created for the dust in the air-strainer; As long as engine body work just can make the dust in the air-strainer discharge immediately.

Fig. 2 is the example structure schematic representation of the engine device of the utility model.
Embodiment
The embodiment of the engine device of the utility model: as shown in Figure 2; Comprise engine body 5 and air-strainer 1; Relief opening 7 places of said engine body 5 are provided with outlet pipe 9, are serially connected with silencing apparatus 8 on the outlet pipe 9, and said air-strainer 1 has suction port 2, relief opening 3 and dedusting mouth 11; The relief opening 3 of air-strainer 1 is communicated with the suction port 6 of engine body 5 through pneumatic tube 4, and air-strainer 1 is communicated with silencing apparatus 8 through dust removing tube 10.
In the foregoing description, an end of said dust removing tube 10 is communicated with the outer wall of silencing apparatus 8, in other embodiments, also can directly be communicated with the outer wall of outlet pipe 9, as long as keep clear of the air outlet of outlet pipe 9.
The foregoing description is when concrete work; Air is got into by the suction port 2 of air-strainer 1; In the relief opening 3 entering engine bodies 5 of cleaned air that filter by air-strainer 1; The dust of formation such as the suspended particulate of air is stayed in the air-strainer 1, because engine body 5 will be with a large amount of CO when work
2Discharge from outlet pipe 9 with CO; This is lower than the pressure in the air-strainer 1 with regard to causing the pressure in outlet pipe 9 and the silencing apparatus 8; Make outlet pipe 9 and air-strainer 1 have pressure reduction; Dust is discharged by outlet pipe 9 through dust removing tube 10 like this, engine body 5 continuous firings, and air-strainer 1 also continues dedusting.
The embodiment of the combine-harvester of the utility model: comprise engine device, structure is as shown in Figure 2, and its content is consistent with the content of the engine device of the foregoing description, repeats no more at this.
