Description

보행형 분무기의 약제 분사장치{Pharmaceutical Injection System for Gait Sprayer}[0001] The present invention relates to a pharmaceutical injection system for a Gait Sprayer,

본 발명은 보행 속도로 이동하는 운반차에 약제 수용 용기를 탑재하고, 약제 용기에 수용된 약제를 운반차에 설치한 동력펌프로 펌핑하여 운반차에 장치한 동력송풍기의 송풍구에 장치한 분사관의 분사노즐에 공급하여 전동송풍기의 송풍구에 장치한 분사관으로 배출되는 바람의 힘으로 약제를 필요한 위치에 송출할 수 있도록 구성한 약제 분사장치에 관한 것으로 분사관의 분출 각도 조정과 분출방향을 가변 자유롭게 할 수 있게 구성하여 효율적인 약제 분사가 이루어지도록 한 것이다.The present invention is characterized in that a medicine container is mounted on a carriage moving at a walking speed, and the medicine contained in the medicine container is pumped by a power pump installed in the carriage to spray the spraying device installed in the ventilation hole of the power blower installed in the carriage The present invention relates to a chemical spraying device which is configured to supply a chemical to a required position by a force of wind which is supplied to a nozzle and is discharged to a spraying pipe installed in a blowing port of an electric blower. The spraying angle of the spraying pipe and the direction of spraying can be freely changed So that efficient drug injection can be achieved.

종래의 분무기를 보면, 보행속도로 이동하는 운반차에 약제 수용용기를 탑재하고, 약제 용기에 수용된 약제를 운반차에 설치한 동력펌프로 펌핑하여 운반차에 장치한 동력송풍기의 송풍구에 배치한 분사노즐에 공급하여 송풍기의 바람으로 약제를 분사하도록 된 것이 사용되고 있다.In the conventional atomizer, a medicine container is mounted on a carriage moving at a walking speed, the medicine contained in the medicine container is pumped by a power pump installed in the carriage, and the medicine is placed in a ventilation hole of a power blower installed in the carriage Which is supplied to the nozzle and is sprayed with the wind of the blower.

그러나 종래의 분무기는 송풍기의 송풍구에 배치한 덕트가 고정형으로 되어서 송풍구의 높이를 상하방향으로 변경할 수 없고, 또 송풍구의 송출방향도 가변할 수 없기 때문에 약제 분사방향을 필요한 방향으로 변경시킬 수가 없어 수목의 적정부위에 약제를 분사할 수 없기 때문에 약제 낭비가 심하게 되는 불편이 있었다.However, in the conventional atomizer, since the duct disposed in the blower of the blower is fixed, the height of the blower can not be changed in the vertical direction and the direction of blowing out can not be varied. Therefore, There is an inconvenience that the medicine waste is severely wasted.
