Atomizing block measuring apparatus

Abstract

The invention relates to a device for determining spraying blockage, which comprises a pressure pump used for extracting and pressurizing liquid in a medical box, a first pressure sensor connected with the pressure pump and used for determining the pressure of the liquid, a filter connected with the first pressure sensor and used for filtering the liquid, a second pressure sensor connected with the filter and used for determining the pressure of the liquid after being filtered, a first switch connected with the second pressure sensor, and a controller respectively connected with the pressure pump, the first pressure sensor, the second pressure sensor and the first switch and used for turning off the first switch after determining that the filter is blocked. The device for determining spraying blockage determines the blockage of the filter during a repeated and cyclic spraying test, indicates blockage alarm, records the pressure during the spraying process, and realizes quantitative test for blockage during the spraying of different chemical pesticides.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a spray clogging measuring device. Background technique [0002] Chemical pesticides play a huge role in promoting food production. The use of chemical pesticides can reduce the occurrence of diseases, insect pests and weeds to a large extent, and reduce the impact of diseases, insect pests and weeds on food crop production. The production practices of various countries have proved that the use of chemical pesticides is one of the most effective and rapid control measures in the existing control process of various diseases, insect pests and weeds, and it is easy to be mastered by farmers during the production process. During the historical period, the use of pesticides will still be one of the most effective methods for humans to fight against diseases, insect pests and weeds. [0003] At present, a large number of chemical pesticide preparations and chemical pesticide mixed p...
