The utility model provides a stem lifting device of a spreading and airing
machine, which relates to the technical field of
wine brewing production equipment and comprises a support and at least one group of stem lifting mechanisms arranged on the support, each stem lifting mechanism comprises a plurality of
shovel plates, a stem lifting swing shaft and a driving component, and two ends of each stem lifting swing shaft are rotatably arranged on the support. The
shovel plates are arranged at intervals in the length direction of the stem lifting swing shaft, the
shovel plates are connected with the stem lifting swing shaft through the stem lifting swing arms, and the driving
assembly is used for driving the stem lifting swing shaft to swing back and forth in a reciprocating mode. According to the peduncle raising device of the spreading and airing
machine, the peduncle raising swing shaft is driven by the driving
assembly to swing in a reciprocating mode, so that the parallel forward urgent pushing action of the shovel plate is achieved, the manual peduncle raising action is highly simulated, and compared with a rotary peduncle raising mode,
vinasse attached to the ground can be scooped up, turned over and fluffy, and the peduncle raising effect is better.
