SOLID MATTER CRUSHING AND FORCE-FEEDING DEVICE

PURPOSE: To provide a device which can crush solid matters without suspending operation of a submersible motor pump even when solid matters are mixed in excreta or the like. CONSTITUTION: A pump motor 11 is driven forwardly through a microcomputer 20 based on a water level information from a water level sensing switch 4, and when the motor current sensed by a current sensor 16 reaches a given value, the motor 11 is started to revolve reversely by a forward and revere changeover relay 14 through the microcomputer 20. The forward and reverse revolutions are repeated successively to release the clamping or clogging of the solid matters on a cutter section and simultaneously the solid matters can be crushed gradually and force-fed.
