Description

Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to a sampling device for feed detection. Background Art

[0002] Cow feed can be divided into six categories: roughage, concentrate, succulent, animal-based, mineral, and feed additives. Cow feed primarily includes Yajin sweet sorghum straw, green corn, alfalfa, Yajin protein mulberry, oat, and corn. The selection of cow feed plays a crucial role in the growth and milk production of dairy cows. Therefore, during the production and feeding of dairy cow feed, it is necessary to sample, collect, and test the feed. Existing sampling devices for cow feed testing are inconvenient to use and cannot be moved to the appropriate location for sampling as needed. Furthermore, the sampled feed is difficult to collect.

[0003] The existing technology has the following shortcomings: Although a sampling device for detecting alfalfa feed for dairy cows ensures sampling accuracy, the aforementioned feed box is connected to the feed collection tube via a magnet. The magnetic force of the magnet is limited. When there is too much feed in the feed box or the feed box is too heavy, the feed box is prone to falling. At the same time, the magnet does not have a positioning and limiting function. When the feed box comes into contact with other objects, the feed box will be pushed, causing the feed box to deviate or even fall. Therefore, it is necessary to invent a sampling device for feed detection. Utility Model Content
