AI Technical Summary
The air intake volume of the air inlet in the existing air conditioning unit of construction machinery cannot be adjusted, which makes it impossible for the air volume to adapt to the proportional relationship between the air volume and the internal exhaust volume. The filter screen is prone to dust accumulation, reducing the practicality of the device.
Design an airflow proportional adjustment duct device, which uses a servo motor-driven pulley and airflow control device to realize the synchronous rotation of the filter screen active control device, including the synchronous rotation of the baffle plate, which includes the baffle plate and the cleaning roller, thereby realizing active control of airflow and cleaning of the filter screen.
It enables active airflow regulation, prevents filter clogging, and improves the applicability and cleanliness of the air conditioning unit.
