Specific embodiment
This utility model is described further below in conjunction with the accompanying drawings：
As shown in FIG. 1 to 3, corn mowing machine cleaning fan arrangements for speed regulation described in the utility model, including speed governing master
Driving wheel 4 and speed governing follower 6, are connected between speed governing drivewheel 4 and speed governing follower 6 by transmission belt 2, and speed governing drivewheel 4 is pacified
It is mounted on blower fan power transmission shaft 7, the outside of speed governing drivewheel 4 arranges adjustment screw mandrel 3, adjustment screw mandrel 3 is arranged on adjustment seat 5, adjustment
Seat 5 is arranged in frame, and speed governing follower 6 is arranged in rotary shaft 13, and the outside of speed governing follower 6 arranges spring 10, spring 10
There is spring base outer end, and speed governing drivewheel 4 includes drivewheel price fixing 8 and drivewheel Moving plate 9, and speed governing follower 6 is fixed including follower
Disk 12 and follower Moving plate 11, one end of transmission belt 2 is arranged between drivewheel price fixing 8 and drivewheel Moving plate 9, and the other end is arranged on
