Embodiment Construction
[0013] The present invention will be further described below in conjunction with embodiment.
[0014] as attached figure 1 As shown, the corn harvester exhaust fan includes a cylindrical housing 1, the two ends of the housing 1 are provided with a central shaft support frame 3, and the central shaft 2 is fixed to the two ends by bearings 4 along the axis in the housing. On the support frame, one end thereof stretches out of the housing 1 and a belt pulley 5 is installed at its end.
[0015] Such as figure 2 Shown, housing 1 is provided with air outlet 9, and air outlet channel 12 is installed on the air outlet 8, and the effect of air outlet channel 12 makes the wind that blower blower blows out fixed direction, in order to be beneficial to align ear drop line.
[0016] Such as figure 1 As shown, the two ends of the central rotating shaft 2 located in the housing and close to the housing are respectively fitted with a mounting base 6.
[0017] Such as figure 2 As shown...

Abstract
The invention relates to a machine for harvesting standing crop corn. Aiming to solve the technical problems that the current fan is low in air output and the blades of the current fan are easy to distort, the invention provides an impurity-removing fan for a corn harvester. The impurity-removing fan comprises a cylindrical casing two ends of which are provided with central rotary shaft support frames, wherein one end of a central rotary shaft stretches out the casing and a belt wheel is installed at the end of the central rotary shaft, and an air outlet is arranged on the casing. The fan is characterized in that two ends, closing to the casing, of the central rotary shaft in the casing are respectively provided with a regular pentagonal mounting seat in a sleeved mode; the mounting surface of each mounting seat and the mounting surface of the mounting seat at the opposite side are on the same plane; the mounting ends of five fan blades and the fan blades are folded into certain angles and are respectively fixed on corresponding mounting surfaces of the two mounting seats through bolts; and at two ends of each fan blade, tractive ribs are arranged between adjacent fan blades. The impurity-removing fan has the advantages that: the structure is reasonable and simple, the maintenance period is greatly prolonged, and the maintenance tasks of operating personnel are reduced.
Description
[0001] technical field [0002] The invention relates to a machine for corn harvesting of upright crops, in particular to a blower fan for the corn harvester. Background technique [0003] When the corn harvester is harvesting corn, the picked ears are lifted to the top by the elevator and then dropped into the peeling machine from the ear drop opening. Because the current corn harvester is difficult to simply remove the ear from the straw during the process of removing the ear, the removed ear will be mixed with certain miscellaneous leaves into the elevator, and the ear and miscellaneous leaves will be lifted by the elevator together. The top then falls into the peeling machine, which increases the workload of the peeling machine and reduces the peeling rate of corn ears. In order to solve this technical problem, a blower fan is installed on one side of the ear drop opening more at present. [0004] The fan currently used is to install a central shaft inside a cylindrica...
