This is designed for groups duster leaves that drop their leaves for the floriculture.; The main structure of the present design is the cost that the naeseol motor is stopped or the operation switch for coupling the driving chamber, by receiving the driving force of the motor provided with a brush rotating in opposite direction to each other by the engagement of the gear main, longitudinal hoejeonbong and, in groups conventional leaf duster consisting of the cover to prevent the drive chamber and a brush is attached to the top plate of the side the upper plate and the brush is installed, which is installed in the combined upper fallen leaves by a brush to fall in the lateral direction, the main , is installed in the drive chamber of the line is positive brush of the species hoejeonbong contact is characterized in that when the flower stalk has been detected comprises a sensor connected to the controller for driving the motor and, it stops the motor if the spine is not detected.; Thus, the subject innovation is an amount between the brush insert and slide the spine sensor is to sense the spine and driving the motor, if the spine is not detected, the sensor sikimeuroseo the motor is stopped, eliminating the operation of the unnecessary motor, thereby eliminating the noise, and in accordance with there is an effect that can improve the working efficiency by preventing energy waste.
