A kind of blower mill, comprise cabinet, the left side of described cabinet is provided with coal-in port, described coal-in port is communicated with described cabinet, the right side of described cabinet is connected with strike shaft coupling by hitting bearing, and described strike bearing runs through the right side of described cabinet and is connected with the strike impeller in described cabinet, the upper end of cabinet described in beater plate is installed on described strike impeller and has been bolted case lid, described box house is provided with backplate, and described case lid is provided with coal outlet.
Described backplate is " U " shape structure, and by handling bolt, is connected between described backplate and described cabinet.
Described backplate also comprises fanning strip, and the quantity of described fanning strip is two, and two fanning strips are fixed on respectively the left and right sides of described case lid by handling bolt.
Described coal outlet is communicated with described cabinet, and described coal outlet be positioned at described strike impeller directly over.
On described strike shaft coupling, be connected with motor, the rotating speed of described motor is 750-1500r/min.
Described beater plate is 16Mn pressboard.
The breach of " U " shape structure of described backplate agrees with mutually with described fanning strip, backplate, fanning strip embed in described cabinet described in described handling bolt-through.
The blower mill obtaining by above-mentioned design of the present utility model, its beneficial effect is:
Can be by opening case lid, change backplate and beater plate, and backplate is overall structure, there is no the gap that can allow coal dust enter.
Accompanying drawing explanation
Fig. 1 is the structural representation of blower mill described in the utility model;
Fig. 2 is the structural representation of backplate described in the utility model;
In figure, 1, cabinet; 11, coal-in port; 12, fanning strip; 13, case lid; 14, backplate; 15, coal outlet; 16, handling bolt; 2, motor; 3, hit bearing; 31, hit shaft coupling; 32, hit impeller; 33, beater plate.
