The working process of the spray pattern marking system of the present invention will be described in detail below with reference to FIGS. 1-2 . Take the boom sprayer with two spray booms as an example, when the spray operation needs to mark the spray width on one side of the spray boom, the driver of the sprayer first cuts off the power supply of the air supply solenoid valve 182 and the liquid infusion solenoid valve 172, so that the air supply Solenoid valve 182 and left side infusion solenoid valve 172 are in closed state; connect the power supply of infusion solenoid valve 171 and gas delivery solenoid valve 181, make transfusion solenoid valve 171 and right side gas delivery solenoid valve 181 be in connected state. Then turn on the power supply of the air pump 11 to make the air pump 11 run. The air pump 11 generates pressure air and is divided into two paths through the air pipe through the tee 161, and one path is delivered to the connecting chamber of the foam generator 13 through the tee 163 and the air solenoid valve 181. In the body 131; the other way of the pressure air enters the airtight foam agent box 12 through the air pipe, and pressurizes the foam agent 15 contained in the foam agent box 12, and the foam agent 15 is inserted into the foam agent box under the action of the compressed air. 12 is pressed out from the infusion tube 20 at the bottom, and delivered to the connection chamber 131 of the foam generator 13 via the volume regulating valve 19 , the tee 162 and the infusion solenoid valve 171 . The foaming agent 15 entering the connecting cavity 131 generates foam under the action of the air pressure and the foaming body 132, and passes through the bellows 133, the foaming cover 134 and the grid 135 to form a swarm foam that can be kept for a long time. It is sprayed and falls on the ground or the top of the crops at equal intervals to form uniform and clearly visible spray width marks, providing instructions for the driver to accurately pick up. The amount of foam agent sprayed out and the size of the distance between the lumps of foam can be regulated by adjusting the opening of the volume control valve 19 as required.

When the sprayer reaches the ground and needs to be changed to the other side of the spray rod for spray width marking, the driver first cuts off the power supply of the infusion solenoid valve 171 and the air delivery solenoid valve 181, so that the infusion solenoid valve 171 and the air delivery solenoid valve 181 It is in the closed state; connect the power supply of the gas delivery solenoid valve 182 and the infusion solenoid valve 172, so that the gas delivery solenoid valve 182 and the infusion solenoid valve 172 are in the connected state. After turning on the power supply of the air pump 11 then, the lump foam can be sprayed out from the foam generator 14, and continue to provide indicator marks for the next row of spraying.
