Air flow type spore trapper

Abstract

The invention discloses an air flow type spore trapper which has the advantages that the area is adjustable, spores and pollen are comprehensively collected in the circumferential direction, and the taking out of the collected spores and pollen is facilitated. The trapper is small in volume and can adapt to different environments. The trapper is characterized in that a middle casing pipe is placedin a caching case and located in the middle of the caching case; one end of the middle casing pipe is placed in the middle of the bottom of the caching case; a communication hole is formed in the middle of the bottom of the caching case and is communicated with the middle casing pipe; the diameter of the middle casing pipe is gradually decreased from bottom to top; the diameter of the caching case is gradually increased from bottom to top; a plurality of through holes are formed in the bottom of the caching case; the diameter of each of the through holes is gradually decreased from bottom totop; a dustproof mesh enclosure is sleeved on the bottom of the caching case; a round table is placed in the middle of the dustproof mesh enclosure; one end of a connecting rod is placed on the roundtable; the other end of the connecting rod penetrates through the communication hole and is placed into the hollow casing pipe.

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...

[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
