Preferably, described front apron and overhead gage are provided with reinforcement.The setting of reinforcement can increase the weight capacity of air main.
Preferably, described air main cross section is half trapezoidal or 1/4th ellipses.When air main cross section is set to trapezoidal, manufacture craft is simpler; And air main cross section be set to 1/4th oval time, add draught area compared with trapezoidal, reduce SR, strengthen ventilation effect, reduce ventilation energy consumption.
Preferably, described front apron lower part is provided with perforate.
Preferably, described perforate is that long strip type flings hole or other is with the hole of the various shapes of not leaking grain hole shape size and being limited.The setting of perforate can strengthen the ventilation effect of grain further, particularly solves transversal ventilation grain face when taking off overlay film dewatering operation, Dead Core Problems bottom warehouse; Perforate size generally recommends it long to being about 20mm, and short is about 1.8-2.0mm, and the horizontal vertical array in hole is unrestricted.
Preferably, described branch air duct interface stretches out main air duct and is about 5cm, its 3-5mm less of branch air duct diameter.
Preferably, described sealing ring is ring-type dual U-shaped structure, and its upper opening shrinks slightly to the inside.Sealing circle is not only easy solves warehouse part air-tightness problem, and facilitates the embedding film of rubber bar, and also leaves the position of installing supply socket and air-blower control switch in the corner of ventilation hole.
Compared with prior art, main air duct in the utility model saves air main by multiple movable cover and is spliced, solve the safety problem that terrace sedimentation causes, facilitate the repairing of body of wall in the cleaning of the insect in main air duct, dust and other impurity etc. and main air duct and junction, ground; Reduce transversal ventilation SR, reduce ventilation energy consumption accordingly, add economy; Solve transversal ventilation precipitation Dead Core Problems.The sealing ring of ring-type double-H groove weld structure simply and effectively solves air-tightness problem, and leaves the installation site of power supply and switch in limited space.
