[0034] The high-pressure nozzle with the switch device 1611 is a commonly known product, which comprises a nozzle head, a nozzle body, a first interface and a second interface, the first interface and the second interface are connected with the middle part of the nozzle body and form a cross shape with the nozzle body, the nozzle head is fixedly installed on the upper end of the nozzle body through threads, and the pesticide spraying hole is located in the middle part of the nozzle head. By replacing the nozzle head with different aperture specifications of the pesticide spraying hole, the pesticide spraying amount can be adjusted, and by loosening the locking screw, the nozzle body can be rotated to adjust the upper end of the nozzle body to adjust or adjust the spraying direction of the pesticide spraying hole. The liquid pressure output by the liquid output port can be observed through the pressure gauge, and the liquid pressure output by the liquid output port can be adjusted by rotating the pressure regulating handle. When the orchard head equipment turns, by pulling the pressure relief handle upward, the pesticide pumped by the hydraulic pump 1603 can be directly returned to the storage tank 1604 through the pressure relief port of the pressure control device and the pesticide return pipe, and the pesticide spraying head 1607 immediately stops spraying pesticide. When the pesticide spraying head 1607 needs to continue to spray pesticide, the pressure relief handle is pulled downward to reset, so that the pesticide spraying head 1607 can spray pesticide again. In actual use, according to the need, if the pesticide is sprayed to the lower fruit trees, the scissor lifting device 4 can be lowered to the appropriate height by controlling the lifting cylinder 403 to make most of the pesticide sprayed downward, and if the pesticide is sprayed to the higher fruit trees, the scissor lifting device 4 can be raised by controlling the lifting cylinder 403 to make most of the pesticide sprayed upward, which can save the consumption of pesticide and reduce the cost, and the use is more convenient. The pesticide spraying device 16 of the utility model uses a separate storage battery 1601 as power, effectively avoids the energy consumption caused by the long transmission chain, and is more economical and environmentally friendly.
