Yellow peach kernel-removing and halving machine and yellow peach kernel-removing and halving method

The invention discloses a yellow peach kernel-removing and halving machine. A transmission assembly is arranged on a base; a plurality of fixing components of which the lower parts are semicircle aresequentially mounted at the top end transmission surface of the transmission assembly; corresponding peach kernel discharge holes are formed in the bottom of the fixing components of which the lower parts are semicircle, and the transmission surface; fixing rods are respectively arranged on two sides of the transmission assembly; two ends of a fixing component of which the upper part is semicircleextend to form a mounting sleeve to sleeve the fixing rods and to be hung on the transmission surface; an upper part lifting assembly is connected with the fixing component of which the upper parts are semicircle, and can drive the fixing component of which the upper part is semicircle to vertically move up and down, so that the fixing component of which the upper part is semicircle is matched with the fixing components o
