The invention discloses a biological
drying aeration device. The device comprises an
aeration panel, a dredging bolt panel and a bottom tray. The
aeration panel, the dredging bolt panel and the bottomtray are arranged from top to bottom.
Aeration holes are formed in the aeration panel. Dredging bolts are arranged at the positions, corresponding to the aeration holes, of the dredging bolt panel, and dredging panel air outlets are further formed. An aeration
pipe is arranged on the bottom tray and is used for conducting aeration to the top of the bottom tray. Meanwhile, a control motor and a
camshaft which is horizontally placed are arranged, and the
camshaft is driven by the control motor to rotate. An
extrusion plate is arranged above a
cam on the
camshaft and fixed to the bottom tray through an elastic
assembly. When the camshaft rotates, the
extrusion plate moves upwards under the action of the
cam and then moves downwards under the action of the elastic
assembly, the
extrusion plate and the dredging bolt panel are fixed, the extrusion plate and the dredging bolt panel simultaneously move up and down, and when the extrusion plate and the dredging bolt panel move upwards, the dredging bolts pass through the aeration holes to achieve dredging operation. According to the biological
drying aeration device, the aeration function is fulfilled, the aeration holes can be effectivelyprevented from being blocked, and the aeration effect is guaranteed.
