The invention relates to the technical field of agricultural machinery, in particular to a device and a method for automatically testing two-dimensional distribution of spraying based on ultrasonic sensor. The device for automatically testing two-dimensional distribution of spraying comprises a support platform, a spraying unit, a two-dimensional moving unit and a control unit, wherein one end of the support platform is provided with the spraying unit; a liquid collecting unit is arranged below the spraying unit; the other end of the support platform is provided with the two-dimensional moving unit; the two-dimensional moving unit is provided with a transverse lead screw and a longitudinal lead screw respectively in transverse direction and in longitudinal direction; the transverse lead screw and the longitudinal lead screw are respectively connected with the control unit through a transverse driving unit and a longitudinal driving unit for respectively controlling the motions of the two-dimensional moving unit in transverse direction and in longitudinal direction; and a testing unit is arranged below the two-dimensional moving unit. Therefore, the measurement of two-dimensional distribution of liquid medicine is realized, the device and the method are suitable for testing the two-dimensional distribution situation of spraying at various types of spray heads, the height of the spray head and the pressure of spraying can be adjusted, and the measurement precision and degree of automation are high.
Description
technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an automatic testing device and method for spray two-dimensional distribution based on an ultrasonic sensor. Background technique [0002] Plant protection is a very important link in the agricultural production process. The application of pesticides in the plant protection process has greatly reduced the damage of crops by diseases, insect pests and weeds, it can reduce the loss of food, and has an irreplaceable role in the protection of vegetables, fruits and other economic crops. [0003] The spray nozzle is one of the important components of the plant protection spray equipment, which plays a decisive role in the safe and efficient use of pesticides. The form of the spray nozzle determines the spraying quantity and spraying method of chemical pesticides. The droplet nozzle is the commonly used nozzle at present, and it plays a decisive role in reducing the los...
