Selective tea picking is intermittent work, and fresh leaves are light weight, the use of vacuum generator compression gas to produce negative pressure, the required vacuum flow is small, in line with the picking requirements. Vacuum generator small size, high vacuum degree, good reliability, in the field of industrial automation is widely used, the use of solenoid valve cooperation to control the fluid, control air pressure and flexibility, easy to operate. Figure 2-5 is a working schematic of the vacuum generator, wherein A is connected by a plastic hose to the inner end of the robot end actuator, for the suction port of fresh leaves, B is connected to the fresh leaf to accommodate the box, the collection of fresh leaves harvested fresh leaves.
