Specific embodiment
In the present embodiment, referring to Figures 1 and 2, the single-screw drawing-in device, including organic frame 6, electrical control mechanism, motor
And screw propulsion rod 4, motor are installed in rack 6, screw propulsion rod 4 is connected to motor, and motor connects electrical control mechanism；The electricity
Machine is variable-frequency motor 1, and variable-frequency motor 1 is connected with speed reducer 2, and screw propulsion rod 4 is connect with speed reducer 2, and entire drawing-in device is only
It is provided with 4, speed reducers 2 of a screw propulsion rod and a variable-frequency motor 1；Screw propulsion rod 4 has the portion of helical blade
Position is inserted into a feed bin 3, is equipped with a pair of of pressing roll mechanism in the end of screw propulsion rod 4, which is set relatively by two
The pressure roller 5 set is constituted, and two pressure rollers 5 are respectively connected with driving device formation constant speed and rotate backward mechanism, and the binder between two pressure rollers 5 is empty
Gap is aligned with the discharge port of feed bin 3；The feed bin 3 is fixed in rack 6.
The top of screw propulsion rod 4 is connect with speed reducer 2, and the output shaft of speed reducer 2 and variable-frequency motor 1 is laterally to connect
