Abstract
The invention relates to a scarifier, comprising a handle and a base, wherein a driving motor arranged in the base is fitted with knife-disc transmitting motion device via a transmitting motion element formed by a second gear, a gear spindle, a third gear and a stem gear, characterized in that the second gear is worked with the gear spindle and fitted with a pressing disc via friction, wherein the pressing disc is engaged with top of the gear spindle and a spring is arranged at the bottom of the pressing disc. The scarifier is novel designed and in simple structure, therefore the scarifier has an excellent application. Operation of the transmitting motion device is realized via friction between the second gear and the pressing disc controlled by the spring pressure, therefore the transmitting motion device lead the knife-disc operating. When the knife-disc is blocked by hard object, the outer loading is stronger than the friction, making an automatic sliding between the second gear and the pressing disc, meantime, the second gear and the gear spindle is fitted neatly, therefore, the driving motor is in blank-run state or works in low loading state. The transmitting motion device prevents the motor from blocking, therefore the device protects the motor, and the motor does not take time to recover, ensuring the normal operation.
