Abstract
The invention discloses an eddy-current booster fan. The booster fan mainly comprises a fan shaft, a fan impeller, fan blades, a fan shell, an air inlet, an air outlet and the like, and is characterized in that the fan impeller is provided with tens of fan blades; the fan blades are made into strip-shaped blades of which the sections are cambered; the fan shell has an appearance of a closed long cylinder; the air inlet and the air outlet are formed on a semicircular surface on the same side of the long cylinder in the longitudinal direction respectively; and the air inlet is designed to have a louver structure.
Description
Technical field
The invention belongs to agricultural machinery technological field, relate to the eddy-current booster fan in a kind of peanut combine dressing mechanism.
Background technique
Traditional cleaning fan volume is big, air quantity is little, power consumption sucks the sandstone weeds greatly, easily etc. causes blade wear big.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides difficult suctions such as a kind of volume is little, air quantity is big, power consumption is little, sandstone weeds, eddy-current booster fan that blade wear is little.
The technical solution adopted for the present invention to solve the technical problems is: a blast fan that fan blade is installed is set in the intermediate portion of fan shaft, blast fan is fixed on the intermediate portion of fan shaft by flange plate, the plurality of fans blade pass is crossed welding and is vertically fixed on the periphery of blast fan, fan blade is made elongate in shape, its section is a circular arc, makes its arc-shaped concave consistent with the sense of rotation of fan shaft during fixing the welding; The closed at both ends of fan long cylinder housing, intake grill and exhaust outlet are arranged on vertical the same side semi circular surface of long cylinder housing periphery, and the exterior design of intake grill becomes shutter, in case sandstone, weeds etc. enter.
The invention has the beneficial effects as follows: difficult suctions such as volume is little, air quantity is big, power consumption is little, sandstone weeds, blade wear are little.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples
Fig. 1 is a plan view of the present invention.
Fig. 2 is a sectional view of the present invention
Fig. 3 is a fan blade view of the present invention.
1. exhaust outlets among the figure, 2. intake grill, 3. fan shaft, 4. blast fan, 5. blower-casting, 6. fan blade.
Embodiment
In Fig. 1, Fig. 2, Fig. 3, blower-casting 5 is fixed on the frame of harvester for peanut by base, profile is an elongated cylinder, vertically upper-lower position is provided with intake grill 2 and exhaust outlet 1 respectively on the semi circular surface of the same side of elongated cylinder, intake grill 2 is designed to shutter, in case sandstone, weeds etc. enter; The centre that bearing that fan shaft 3 is provided with by two ends and bearing support are installed in long cylinder blower-casting 5 both ends of the surface, a blast fan 4 that fan blade is installed is set in the intermediate portion of fan shaft 3, blast fan 4 is fixed on the intermediate portion of fan shaft 3 by the two ends flange plate, plurality of fans blade 6 is vertically fixed on the periphery of blast fan 4 by welding, fan blade 6 is made elongate in shape, its section is a circular arc, makes its arc-shaped concave consistent with the sense of rotation of fan shaft during fixing the welding; The closed at both ends of blower-casting 5, the middle fan shaft bearing seat of installing; Working principle is: be made up of tens of fan blade 6 on the blast fan 4, its similar huge gas turbine impeller, when impeller rotates, air in the middle of the impeller blade is subjected to action of centrifugal force, border movement towards impeller, air enters the toroidal cavity of the pump housing there, return impeller then again, again carry out shuttling movement in the same way again from the starting point of blade, because air is quickened uniformly, the circulating air flow that is produced during the impeller rotation makes air scurry out with the form of helix, the effect of arc shaped blade is the air-flow that enters blower-casting to be moved form the eddy current supercharging in toroidal cavity, the above analysis so air leaves the pump housing with high energy, produces the air quantity (pressure that it produced is 12-17 times with rotating speed diameter centrifugal blower) that is several times as much as conventional fan.
Claims (2)
1. eddy-current booster fan, mainly form by fan shaft, blast fan, fan blade, blower-casting, intake grill, exhaust outlet etc., it is characterized in that: tens of fan blade are installed on the blast fan, fan blade is made strip, its section is a circular arc, makes its arc-shaped concave consistent with the sense of rotation of fan shaft during the fixed installation welding.
2. eddy-current booster fan according to claim 1, it is characterized in that: the profile of blower-casting is the elongated cylinder of a sealing, vertically upper-lower position is provided with intake grill and exhaust outlet respectively on the semi circular surface of the same side of elongated cylinder, and intake grill is designed to shutter.
