DEVICE FOR TAKING AND DELIVERY OF LOOSE MATERIALS Russian patent published in 1997 - IPC

FIELD: materials handling; taking, metering out and transportation of loose materials. SUBSTANCE: device made as separate mechanism has flexible auger hose 1, length of rigid pipe 2 with longitudinal side key 3, rectangular cutout 4 on the top and limiter 6, length of rigid pipe 6 with outer splines 7 and limiter 8, single-start flexible auger 9 with auger rod branch 10 with outer splines and auger rotating motor. Pipe 2 with side key 3, rectangular cutout 4 and limiter 5 form unit of detachable connection with hopper. Pipe 6 with outer splines 7 and limiter 8 form unit of detachable connection with loose material receiver. Auger rod branch 10 with outer splines serves for detachable connection with motor. In mounting, pipe 2 of device is fitted in cylindrical socket of hopper and pipe 6, in socket of receiver and rod branch 10 of auger 9 comes into engagement with motor secured on hopper. Device can be used at taking and delivery of loose materials of any type, including chopped powders in pyrotechnical systems of different application, for instance, mortar type seismic signal sources used in seismic prospecting. Pyrotechnical system can have several hoppers with different grades of powder and more than one receiver, in particular, several sources of seismic signals operating in parallel. In case of failure device can be easily replaced by spare one. EFFECT: improved operating characteristics of device owing to the fact that mechanism is provided with detachable connections with hopper and receiver. 1 dwg
