A plurality of feed holes are provided on the side wall of the holding tank away from the dual-output reduction gearbox. Among them, the screeding member is fixedly connected to the side wall of the holding tank where the feed holes are provided. When the screeding member is in a horizontal state, the mouth of the holding tank faces upward and the plurality of feed holes are located above the screeding member.
[0011] In a possible implementation, the first upright post, the second upright post, the first slide rail, the first slider, and the first rolling wheel are combined into a lifting unit. The number of the lifting units is two, and the two lifting units are symmetrically arranged.
