The application discloses an intelligent feeding control system and method of a dumper, relates to the technical field of dumper feeding, and comprises a coal type identification module, a material level metering module, a dumper control module, a feeder control module, a belt scale reading module and a PLC controller. The PLC controller is electrically connected with the coal type identification module, the dumper control module, the feeder control module and the belt scale reading module. The feeder control module is connected with a frequency converter for controlling a cam motor and an outlet power component for controlling the discharge port area of an activated feeder. A plurality of different coal feeding operation control models are built in the PLC controller. The intelligent feeding control system and method of the dumper adopt the above structure and steps, select a suitable model according to the coal type to guide the dumper operation, and ensure the stable operation of the belt conveyor.

This utility model discloses a hoisting device for particleboard after production and forming, including a hoisting frame and a particleboard clamping device assembly. The particleboard clamping and placing assembly includes: a base connecting plate, which is bolted to one end of a side plate; a lifting hydraulic cylinder is installed on the upper end of the base connecting plate; a lifting guide column is telescopically moved on the upper end of the lifting hydraulic cylinder; a fixing plate is installed on the upper end of the lifting guide column; the fixing plate is bolted to the upper end of a clamping moving plate; and the side plate is fixedly installed on both sides of the hoisting frame. Driven by the lifting hydraulic cylinder, the particleboard can be clamped quickly and accurately. The coordinated action of multiple clamping plates ensures that each particleboard is evenly clamped, avoiding slippage or falling of the particleboard due to unstable clamping. It ensures that the clamping plates are clamped synchronously on the same horizontal plane, avoiding uneven force distribution and the tediousness and instability of manual binding. Multiple particleboards can be hoisted simultaneously, improving production efficiency.
