A wind-flow spore trap

Abstract

An air flow spore catcher disclosed by the invention discloses a catcher which can collect spores and pollen in a circumferential direction and is convenient for taking out the collected spores and pollen through an adjustable passing area. Small size, able to adapt to different environments. It is characterized in that the middle casing is placed in the buffer box and is located in the middle of the buffer box, one end of the middle casing is placed in the middle of the bottom of the buffer box, a communication hole is opened at the middle of the bottom of the buffer box, and it is connected with the middle casing The diameter of the middle casing gradually decreases from bottom to top, the diameter of the buffer tank gradually increases from bottom to top, and the bottom of the buffer tank has a plurality of through holes, and the diameter of the through holes gradually increases from bottom to top. Reduce, the dust-proof net cover is placed at the bottom of the buffer box, the middle part of the dust-proof net cover is provided with a round platform, one end of the connecting rod is placed on the round platform, and the other end is placed in the hollow sleeve through the communication hole.

Description

technical field [0001] The invention relates to a wind-flow spore catcher, which relates to a catcher for catching and collecting spores and pollen by using airflow, and belongs to the field of environmental detection. In particular, it relates to a catcher which can collect spores and pollen in a circumferential direction and is convenient for taking out the collected spores and pollen through an adjustable area. Background technique [0002] At present, the spore trap is developed to collect spores and pollen dust particles in the air. Due to factors such as climate and environment, spores of disease-causing bacteria flow in the air, and pollen dust is mixed in the air. In order to detect air quality and prevent diseases Diffusion, collect the spores in the air through the trap, and check the internal disease source spore data to take measures. It is also one of the auxiliary equipment for monitoring crop diseases in the agricultural insurance process. In the previous spor...

Problems solved by technology

[0002] At present, the spore trap is developed to collect spores and pollen dust particles in the air. Due to factors such as climate and environment, spores of disease-causing bacteria flow in the air, and pollen dust is mixed in the air. In order to detect air quality and prevent diseases Diffusion, collect the spores in the air through the trap, and check the internal disease source spore data to take measures. It is also one of the auxiliary equipment for monitoring crop diseases in the agricultural insurance process. In the previous spore capture process, Both use a motor to drive two capture blocks, and the capture blocks are rotated to capture spores. However, in an outdoor open-air environment, affected by the external air flow, the spore collection fluctuates greatly, and stable capture cannot be carried out. Due to the difference in traits, the individuals grown are also different, so the collection is not comprehensive enough, and the rotation of the capture plate will cause airflow disturbance, so that the spores are expelled by the airflow. Some existing spore traps are installed on the ventilation pipe. There are several through holes, through which the external airflow is sucked in by the internal fan. Driven by the airflow, the spores are sucked into the ventilation pipe for capture. Since the size of the throughholes on the ventilation pipe is fixed, other slag will be included during the capture. Inhalation of foreign matter, the size of the through hole or the passing area of ​​the spores cannot be adjusted, the through hole is continuously open, and the existing traps are large in size and cannot capture the spores at high places. The traps that can collect high places are available Difficult to remove spores
