FIELD: mechanics.
SUBSTANCE: pressure-equalising valve is arranged in a bin-accumulator. Note here that the proposed device incorporates additionally an intermediate bin with flaps and screen partitions to separate it into three compartments arranged one above the other, a loading bin communicating with the intermediate bin central compartment via a pneumatic line, a conveyor arranged between the intermediate bin lower compartment and feeder-accumulator, a down level pickup with its output connected to the conveyor motor, a unit of filters connected via vacuum line with the loading fan, and, further on, with the intermediate bin upper section. Note that the control unit inputs are connected to the computer and weight shaping circuit component outputs, while its outputs are connected to the drives of the switching flap and unloading fan respectively.
EFFECT: higher efficiency.
