Abstract
The utility model relates to a novel knapsack mist and powder spraying machine fan impeller. An impeller blade replaces the original great circle impeller structure, and the shape of the impeller blade adopts the structure that a straight line part is connected with a circular arc part. The impeller blade causes the impeller to reach good work effect through adopting suitable linear tilt angle, circular arc radius and the included angle of the intersection tangent of the circumference of the impeller and the circular arc. The effective power is improved.
Description
The utility model relates to the spray duster machine technology.
At present, no matter the knapsack sprayer-duster draught fan impeller that China is commonly used is plastic article or with metal, all adopts orthodrome (generally to adopt radius of arc R=125mm, circular arc chord length ρ=106mm) the equal mode for cloth of blade (as shown in Figure 1) is made, and fan efficiency is not satisfactory.
The purpose of this utility model is to provide a kind of knapsack sprayer-duster draught fan impeller of practicality and high efficiency.
This model utility is achieved in that as shown in Figure 2, is distributed in the blade 2 on the impeller 1, the structure that its shape adopts the straight section I to be connected with the circular arc portion II.The straight section I adopts β
1=20 °-24 ° tilt angle, the circular arc portion II adopts the radius of arc of R=46-50mm, and the crossing tangent line of circular arc portion II and impeller I circumference adopts β
2=36 °-40 ° angle.
This model utility knapsack sprayer-duster draught fan impeller because the structure that its blade adopts straight line to be connected with circular arc has overcome the deficiency that original orthodrome blade exists, has improved the useful horsepower of impeller greatly.
Accompanying drawing 2 is this model utility impeller schematic representation.
Embodiment 1: as shown in Figure 2, and the structure that the blade 2 of this novel knapsack sprayer-duster draught fan impeller 1 adopts the straight section I to be connected with the circular arc portion II.The straight section I adopts angle of inclination beta
1=2
1° circular arc portion II radius of arc R=47mm, and intersect tangent line angle β with impeller 1 circumference
2=39 °.
Embodiment 2: as shown in drawings, and the structure that the blade 2 of this novel knapsack sprayer-duster draught fan impeller 1 adopts the straight section I to be connected with the circular arc portion II.The straight section I adopts angle of inclination beta
1=23 ° of circular arc portion II radius of arc R=48mm, and intersect tangent line angle β with impeller 1 circumference
2=38 °.
Embodiment 3: as shown in drawings, the blade 2 of this novel knapsack sprayer-duster draught fan impeller 1 adopts straight section: the structure that is connected with the circular arc portion II ° straight section I adopts angle of inclination beta
1=24 ° of circular arc portion II radius of arc R=50mm, and intersect tangent line angle β with impeller 1 circumference
2=40 °.
Claims (1)
