Description

Technical Field

[0001] The utility model belongs to the technical field of veterinary drug production, and in particular relates to a drug quantitative sampling device. Background Art

[0002] Veterinary soluble powders need to be produced in a closed workshop. The production of some veterinary drop drugs requires the mixing of soluble powders and solvents. After mixing the ingredients, they need to be fully stirred. After fully stirred, they can be packaged. Before packaging, sampling and testing are required to mainly test whether the ingredients of the veterinary drugs meet the standard requirements. Veterinary soluble powders are usually mixed and stirred in a batching tank. A sampler needs to be inserted into the batching tank for sampling. The batching tank is usually designed as a closed structure. In order to facilitate sampling, a sampling port is opened on the batching tank. The cover on the sampling port is opened, and the sampler is inserted into the sampling port to sample and dissolve the soluble powder, and then make drops. The efficiency of the entire sampling work is not high. In order to improve the sampling efficiency, automatic or semi-automatic sampling equipment can be installed on the sampling port, which is highly complex and inconvenient for daily maintenance and management.

[0003] To solve the above problems, a Chinese patent with publication number CN220019016U discloses a sampling device for production and detection of veterinary soluble powders. The prior art lifts the cover plate by installing a sampling bottle, thereby allowing the veterinary drug to enter the sampling bottle. However, when the veterinary drug enters the sampling bottle, the falling speed of the veterinary drug cannot be controlled, and residual veterinary drugs in the extension tube will enter the sampling bottle, resulting in inaccurate sampling volume and inconvenience in use.
