The bottom surface of the gauge layer is provided with a heat dissipation port communicating with the lower part of the box body.

In the above technical solution, at least two parallel pipe joints are provided on the liquid outlet. Thus, two people can spray at the same time.

In the above technical solution, the box body is provided with a charging interface connected to the rechargeable battery.

When it is necessary to spray the crops, first check the condition of the equipment, then install the hoses for liquid inlet and spray, take out the measuring device from the measuring device layer, measure the required drugs and prepare the chemical liquid, and adjust the timing switch. Use the remote control for long-distance control. When spraying, just put the suction filter on the liquid inlet hose into the liquid storage barrel, put the suitcase, press the control switch to turn on the power supply of the diaphragm pump, and the fan will work at the same time to reduce the temperature in the box. When the spraying is over, fill the liquid storage barrel with clean water and start the equipment for cleaning. Finally, quickly remove the inlet and outlet hoses through the inlet and outlet connectors. When the spray pressure drops significantly, insert the external charger into the external input socket on the box to charge the power supply.

Due to the application of the above-mentioned technical solutions, the utility model has the following advantages compared with the prior art:

1. The utility model is designed as a suitcase, which is separated from the liquid storage barrel, the liquid inlet device and the liquid outlet device. It is small in size, easy to carry, and easy to disassemble.
