Nut hull breaking machine with semi-automatic charging device

The utility model discloses a nut hull breaking machine with a semi-automatic charging device. The nut hull breaking machine is mainly composed of a nut taking device, a machine frame, a fixed blade, a moving blade, a moving knife rest, a motor, a speed changing box and the semi-automatic charging device, wherein the semi-automatic charging device is mainly composed of a controller, a magnetic valve, a hopper, columns, correlation optical fibers, a charging bucket and an audio alarm. The hopper is arranged under a gap between the moving blade and the fixed blade, the magnetic valve is arranged at the bottom of the hopper, the columns are arranged under the hopper and located on two sides of the charging bucket, the correlation optical fibers are fixed on two columns and correspond to through holes in the upper portion of the charging bucket. The correlation optical fibers transmit full charge information to the controller, and the controller enables the magnetic valve to be closed and starts the audio alarm to give out an alarm. The nut hull breaking machine improves the nut hull working efficiency and further has good nut hull breaking effect. Due to the fact that the nut hull breaking machine adopts the semi-automatic charging device, the problem that workers need to keep watch the machine is solved, and the labor amount is greatly decreased.
