Design of a punching machine for the bacteria bag of the bag cultivated mushroom

To improve the level of mechanization and automation of mushroom production, an automatic punching machine was designed for the bag cultivated mushroom after the first batch of boom. The machine using several mechanisms such as compound three sliders mechanism, crank slider mechanism and cylindrical CAM mechanism, can push the prepared nails into the cultivation bag along the diameter direction at 4 different uniform locations on the circle. It has functions of automatic feeding, punching holes and unloading.Compact, high efficient, no bacteria contamination and automatically continuous uninterrupted operation, this machine can be a part of mushroom production line with the cone machine, grinder, mixer, bagging machines, inoculating machine and water machines for largescale production based on bag cultivation technology.
