Problems solved by technology
The existing problem is that the size of the impurity outlet of the existing grain winnowing machine does not change, and the wind speed of the impurity outlet does not change when the wind speed of the fan remains unchanged, so it cannot adapt to different impurity flow rates and impurities of different sizes

Embodiment Construction
[0015] The present invention will be described in detail below in conjunction with the accompanying drawings, as shown in the figure: the grain winnowing machine of the present embodiment includes a casing and a blower fan, the casing has an air duct, and the top of one end of the air duct is vertically connected with a feed material. The other end of the air duct is horizontally connected with an impurity outlet, and the bottom of the air duct is connected with a finished product outlet. The fan blows along the axial direction of the air duct and blows out impurities from the impurity outlet. An air regulating plate that swings around the drive shaft and a rotating motor that drives the air regulating plate, the driving shaft is located on the top of the impurity outlet and the axial direction is horizontal and vertical to the air duct. The grain enters the air duct from the feed hopper, and the fan blows into the air duct. The wind blows the lighter impurities such as chaff t...

The invention discloses a grain fanning-sorting machine which comprises a case and a draught fan. An air flue is formed inside the case; the upper portion of one end of the air flue vertically communicates with a feeding hopper; the other end of the air flue horizontally communicates with an impurity outlet; the lower portion of the air flue communicates with a finished product outlet; the draught fan blows wind into the air flue in the axial direction of the air flue and blows impurities out through the impurity outlet; a wind adjusting board swinging around a drive shaft and a rotation motor for driving the wind adjusting board are arranged in the impurity outlet; and the drive shaft is located on the top of the impurity outlet and is axially and horizontally perpendicular to the air flue. An angle sensor is arranged on the drive shaft and used for detecting the rotation angle of the drive shaft; and an angle displayer is arranged on the outer side of the case. The angle sensor detects the rotation angle of the drive shaft, the rotation angle is displayed on the displayer, and a user can observe the rotation angle conveniently at any time.
Description
technical field [0001] The invention relates to the field of agricultural machinery, in particular to a grain winnowing machine. Background technique [0002] Grain winnowing machine is a device used to separate lighter impurities in grains from grains. Its principle is that according to the principle of aerodynamics, according to the difference in density of light and heavy materials, the lighter impurities are blown out from the impurity outlet by the fan, while the lighter impurities are blown out from the impurity outlet by the fan. The heavy finished grain falls under gravity, separating the grain from impurities. The existing problem is that the size of the impurity outlet of the existing grain winnowing machine is constant, and the wind speed of the impurity outlet remains unchanged when the wind speed of the fan is constant, so it cannot adapt to different impurity flows and impurities of different sizes. Contents of the invention [0003] In view of this, the tec...
