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 40%-50%, 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, further reducing fan air requirements.

Heavy Axle Load Heavy-Duty Grating

Modular structural steel frame withstands repeated heavy‑truck drive‑over loads with minimal deformation and low risk of 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.
