Crop disease spore capturing, separating and detecting device

Abstract

The invention discloses a crop disease spore capturing, separating and detecting device. The crop disease spore capturing, separating and detecting device comprises a collecting box, an electric control box, a sampling opening and a capturing channel, wherein the sampling opening for introducing disease spores is formed in the upper surface of the collecting box; the bottom of the collecting box is communicated with the capturing channel; a collecting adhesive tape for capturing the spores is arranged in the capturing channel; the collecting adhesive tape is driven by electric wheels at two ends to transmit; the electric control box is arranged on the right side of the collecting box and the capturing channel; a fan, an electric control module of the electric wheels and a microscopic imagecollecting module are arranged in the electric control box; the fan is arranged on the side wall of a box body of the collecting box and the capturing channel; and a directional air source is generated to drive the spores in the collecting box to be uniformly separated and settled to the collecting adhesive tape. The device separates the spores captured in the collecting box, so that the spores are uniformly settled to the collecting adhesive tape with a hollow design, and mutual stacking of collected materials is avoided; and by the advantages of small size, light weight and the like, the crop disease spore capturing, separating and detecting device can be mounted under an unmanned aerial vehicle, a large space monitoring range is covered, and the application prospect is wide.

Description

technical field [0001] The invention relates to a device for capturing and detecting crop disease spores transmitted in the air, in particular to a device for capturing, separating and detecting crop disease spores. Background technique [0002] Airborne transmission is one of the main ways for crop disease spores to spread. Timely monitoring the concentration of crop disease spores in the air is an important means for early warning of disease epidemics. The current fixed-volume spore traps are expensive and cannot be deployed in large areas. Moreover, it is large, heavy, and poor in mobility. Basically, it can only be fixed at the ground station for collection. On the one hand, this capture method cannot cope with the diversion of spore transmission caused by changes in wind direction; on the other hand, it cannot capture the air boundary layer. Mobile crop disease spores in the air at high altitudes, resulting in insufficient surveillance coverage. In addition, due to th...

The current fixed-volume spore traps are expensive and cannot be deployed in large areas

Moreover, it is large, heavy, and poor in mobility. Basically, it can only be fixed at the ground station for collection. On the one hand, this capture method cannot cope with the diversion of spore transmission caused by changes in wind direction; on the other hand, it cannot capture the air boundary layer. Mobile crop disease spores at high altitudes, resulting in insufficient surveillance coverage

In addition, due to the complex composition of the aerosol, the existing spore traps do not have the separation function, resulting in stacking of collected objects, which poses a challenge to the accuracy of microscopic image detection

[0003] For example, the 201810762097.8 patent application document discloses a crop disease spore suspension enrichment detection device and method in the air. The system consists of a hot air balloon, a controller, a flying device and a spore trap. The controller controls the flying device to fly with the spore trap. To the preset point, control the auxiliary fan to establish an air duct leading to the spore trap, and collect images through the lens, but it can only judge the number of spores to determine the source, and cannot separate the spores for further analysis, and the scene and power of the hot air balloon are not enough.
