Microbial aerosol sampling device based on animal husbandry and veterinary medicine

Abstract

The invention discloses a microbial aerosol sampling device based on animal husbandry and veterinary medicine. The device comprises a mounting bracket, a fixed box body arranged on the mounting bracket and a six-stage sampler main body arranged in the fixed box body, a first electric push rod is arranged at the top of the fixed box body, a fixing frame is arranged at the end part of the first electric push rod, a supporting frame is movably installed in the fixing frame, a cleaning piece is installed on the side, close to the supporting base, of the supporting frame, and a placing piece is installed on the side, away from the supporting base, of the supporting frame. The microbial aerosol sampling device based on animal husbandry and veterinary medicine is different from the prior art, a functional rotating mechanism can drive an aluminum alloy disc to sequentially rotate to the position below the cleaning piece and the placing piece, the aluminum alloy disc is disinfected through the cleaning piece, a culture plate is placed in the aluminum alloy disc through the placing piece, and combined installation of the sampler is completed. And a reciprocating cleaning assembly drives a shifting frame and a cleaning brush to slide in the sliding frame, so that a filter screen is cleaned.

Description

technical field [0001] The invention relates to the technical field of air microbial sampling and detection devices, in particular to an aerosol sampling device based on animal husbandry and veterinary microorganisms. Background technique [0002] With the development of innovative technologies such as the new generation of Internet, mobile Internet, cloud storage, Internet of Things, and intelligent collection terminals (such as RFID, sensors), animal husbandry is becoming more and more intelligent, and has gradually formed a concept that combines modern ecological breeding. Smart agriculture and animal husbandry, through online supervision services such as breeding, epidemic prevention, quarantine, slaughtering, circulation, distribution, harmless treatment, animal product safety, and major disease early warning, realize resource integration, data sharing, and business collaboration in animal husbandry; biogas Sol refers to aerosols containing biological particles, includi...

Problems solved by technology

[0003] However, we found in actual use that the existing Anderson type six-stage sieve air impingement sampler consists of 6 layers of 400 micro-hole aluminum alloy discs, an agar plate placed under each disc, and an additional The sealing rubber ring between the two aluminum alloy discs, the medium plate placed on each disc and three spring clips for positioning and locking are fixed. When sampling, the sampler is connected to the sampling pump through a hose Sampling can be started, as the Chinese utility model whose notification number is CN204999906U discloses a kind of percussive air microbial sampler with multi-stage sieve holes, including multi-stage impactor and sampling medium, and said multi-stage impactor includes multiple Stacked sieve tray and sieve hole sampling head, air enters the sieve tray from the sieve hole sampling head, the sieve tray is an aluminum alloy disc with tiny nozzle holes, and the tiny nozzle holes gradually become smaller along the direction of air flow, The air microbial sampler simulates the anatomical structure and aerodynamic characteristics of the human respiratory tract, adopts the usual impact principle, collects the microbial particles suspended in the air on the surface of the sampling medium according to the size and grade, and then co-cultures and further microbial However, the existing sampling process requires the cooperation of multiple people to complete the assembly of the sampler, which not only increases the workload of the operator, but also increases the cost of detection. The most important thing is that it also increases the activities of personnel, which in turn affects the accuracy of sampling results; in addition, compared with the outside air, the air in the enclosure contains more forage particles, dander and other impurities. Especially after starting the sampling pump, the activities of these impurities in the air are also more intense, and it is very easy to block the intake pipe of the sampler, which greatly affects the normal sampling work. Therefore, we propose a method based on animal husbandry and veterinary medicine. Microbial Aerosol Sampling Device
