Gear frame is installed on, the gear frame is connected to the front end of the feeding box body.
It is further characterized by：
The helical-blade bobbin includes gradual change thread segment and uniform screw thread section, the gradual change thread segment correspondence charging aperture
Set, between the uniform screw thread section correspondence charging aperture and the discharging opening, the flight pitch edge of the gradual change thread segment
Feed direction becomes larger；
The first bearing seat is installed on the front end side wall of the gear frame by connecting plate, and the second bearing seat passes through
Connecting plate is installed on the front end side wall of the feeding box body；
The gear frame is welded in the front end side wall of the feeding box body by reinforcing plate；
There is fixed plate by Stud connection in the top of the gear frame, the reductor and the motor are respectively arranged in
The fixed plate；

In case；
It is further further characterized in that：
The gradual change thread segment at least includes three circle gradual change screw threads；
The case is connected to the gear frame by support bar.
After structure of the present utility model, the transmission of helical-blade bobbin changes by sprocket wheel, chain replacement belt, belt wheel, then
Realize driving by reductor and motor, it is to avoid the defect that belt easily skids when leaning on belt, belt wheel transmission in the prior art,
Effectively increase the reliability of driving.Also, the arrangement between the helical blade on helical-blade bobbin is improved, is adopted
Material can be first compacted well with the gradual change thread segment at charging aperture, then realize uniformly sending by uniform screw thread section
Material, so as to further ensure feeding effect.
Brief description of the drawings
