Embodiment
According to accompanying drawing the utility model is described further below.
Like Fig. 1, Fig. 2 and shown in Figure 5, be respectively the 3-D view of general structure rearview, end view and the transverse slat 3 of precision sower blower fan transmission of the utility model air-sweeping type corn and fixing device for installing.Blower fan transmission of said air-sweeping type corn precision sower and fixing device for installing comprise frame 10, blower fan frame 6, transverse slat 3, driving pulley 7, passive belt wheel 2.
The side plate of both sides, blower fan frame 6 top respectively has two strip holes 602.The transverse slat 3 of blower fan frame 6 is an I shape, and 3 liang of vertical planes of transverse slat are provided with the blower fan frame connecting hole 303 that cooperates with strip hole 602, through being threaded, makes transverse slat 3 be fixed on blower fan frame 6 middle parts.Simultaneously, transverse slat 3 plane of structures are provided with through the fixing blower fan installing hole 301 of blower fan 1 of bolt connection, and adjusting screw(rod) installing hole 302.Passive belt wheel 2 is installed on the blower fan axle 101 of blower fan 1.
