The invention discloses a hawthorn pitting and slicing integrated machine. The hawthorn pitting and slicing integrated machine is characterized by comprising a machine frame, and the machine frame isprovided with a feeding mechanism, a conveying mechanism, a centralizing mechanism, a pitting mechanism and a slicing mechanism sequentially in the moving direction of hawthorns. By means of the hawthorn pitting and slicing integrated machine, when the hawthorns are pitted and sliced, the hawthorns falling into a material hopper are sequentially arrayed through a rotating shaft, the arrayed hawthorns can neatly fall onto a chain plate, it can be ensured that all tools can work during pitting, the power consumption of a motor is reduced, and the hawthorns can be processed in batches after beingarrayed. Meanwhile, the centralizing mechanism used before the hawthorns are pitted is driven by a gear to work and has the high centralizing efficiency and speed. Compared with an existing method ofmanually positioning hawthorns, the labor intensity of workers is reduced, and the time for making a preparation before the hawthorns are processed is greatly shortened. The integrated machine is stable in hawthorn processing process, the processing quality is ensured, and the hawthorn pitting and slicing integrated machine is economical, practical and high in efficiency.
