Description

TECHNICAL FIELD

[0002] Livestock farming is an important part of modern agriculture, and is of great significance to animal health and production efficiency. With the progress of science and technology, rapid and accurate sampling and detection of livestock and poultry has become an indispensable part of the livestock industry. Traditional sampling methods rely mainly on manual operation, which is not only inefficient, but also susceptible to subjective factors, making it difficult to ensure the accuracy and consistency of sampling. Therefore, in recent years, researchers have been working to develop more efficient and accurate sampling and detection equipment to meet the growing demand.

[0003] The sampling devices commonly used in the prior art mainly include manual pump type samplers and some simple mechanical auxiliary tools. These traditional sampling devices are mostly simple in structure and mainly divided into two categories: manual pump type samplers and mechanical auxiliary tools. The manual pump type sampler is suitable for liquid sample collection, while the mechanical auxiliary tool is mainly used for sampling of solid or semi-solid substances. However, whether it is a manual pump or a mechanical auxiliary tool, they are often designed only for a specific type of sample, i.e. either specifically for liquids or focused on solids. In addition, many of these devices do not take into account the subsequent cleaning and maintenance requirements, resulting in significant challenges when converting between different sample types or multiple batches of samples using the same device.

[0004] The current sampling device has certain limitations, mainly because these devices mostly use a single sampling method, and lack convenient ways to replace and clean the sampler, which has shortcomings in operational flexibility and adaptability to diverse samples. SUMMARY
