Receiving Pit Dust-proof Flap Device

Automated Truck Intake Opening & Energy-Saving Dust Suppression

Highlights

Automatically opens under grain weight during unloading and self-closes immediately after.
Reduces required exhaust air volume by up to 60%, significantly lowering fan power consumption.
Prevents dust escape from truck intake pits during high-volume gravity unloading.
Heavy-duty wear-resistant steel grid supports heavy axle loads from unloading trucks.

Performance Features

Gravity-Actuated Self-Closing Mechanism

Counterweighted flap blades respond instantly to grain flow gravity, opening only active discharge zones while keeping idle pit sections completely sealed.

Airflow Reduction & Energy Savings

By sealing inactive pit surface areas, the system concentrates negative pressure airflow exactly where dust is generated, cutting fan air requirements by over 50%.

Heavy Axle Load Heavy-Duty Grating

Modular structural steel frame withstands repeated 80-ton heavy truck drive-over loads without deformation or blade jamming.

FAQ

Does the flap mechanism jam when handling wet grain or trash?

Specially designed smooth pivot hinges and angled deflector plates ensure self-cleaning operation even with high-moisture corn or straw debris.
