The trough-type turning machine is the most widely used fermentation turning equipment, including walking fermentation tank, walking track, power-taking device, turning part and transfer tank device (also called transfer vehicle, mainly used for multiple slot usage). The turning part adopts advanced rolling and simple transmission, and there are two kinds of lifting type and non-lifting type. The liftable type is mainly used in the working situation where the width of the tank body does not exceed 5 meters and the turning depth does not exceed 1.3 meters. The bearing seat of the turning device is fixed on the turning frame, and the two main shafts are fixed in the bearing seat, and each main shaft is welded with a number of turning shafts arranged at a certain distance and staggered at a certain angle. There are turning plates welded on the shaft. The turning device is connected with the traveling device through a pin shaft. This machine is suitable for aerobic fermentation and can be used in conjunction with solar fermentation chambers, fermentation tanks and transfer machines. The matching fermentation tanks can discharge materials continuously or in batches. High efficiency, stable operation, sturdy and durable, even turning and throwing.
