Description

Hay sampling device

Technical Field

The utility model relates to a fodder sampling test technical field specifically is to relate to a hay sampling device.

Background

At present, the hay bundle production technology in animal husbandry production is mature day by day and is scaled more and more, so that the correct sampling and the evaluation of the nutritional value of hay are extremely important. However, only grain and concentrate samplers are available on the market today, the production and processing technology thereof is mature, and the production of coarse fodder samplers, especially hay samplers, is almost blank. Most hay samplings can only be manually carried out, time and labor are wasted, a bale structure is damaged, samples are not representative, and due to the fact that hay bales are high in density, a common manual hay sampler generally needs large strength to complete sampling when used, and sampling difficulty of female samplers with small strength is large; hay samplers on the market are also motorized, imported, but they all exist or have a slow sampling rate; or the sampling amount is small, and the weight of the sample to be detected is required to be repeatedly sampled for multiple times; or the sample is directly retained in the sampling tube/sampler after sampling, and the sample cannot be packaged quickly, so that the moisture detection result is influenced; or part of the sample stays in the sampling tube/sampler, and the sample is easy to leak when transferred from the sampling tube/sampler to the storage bag, so that the sample is not completely collected, and the detection result is influenced.

Chinese patent CN202547972U discloses a novel electric hay sampler which greatly speeds up the sampling progress and reduces human factors, but because the diameter ratio of the sampling cylinder of the sampler is smaller, the hay sample is not easy to be discharged after being sampled, and the missed scattering of the hay sample after being sampled is easy to be caused by slight carelessness, which results in incomplete sampling and collection and affects the detection result; in addition, the hay sampler of this kind of structure is in the sampling process usually, because the inner space of sampler barrel is limited, the hay is easily compacted after continuously getting into the sampler barrel, and electric drill operating time is longer, the hay gets into the sampler barrel the more, the hay is just by the compaction degree more big, further sample also will be more hard, the hay in the sampler barrel will block in the sampler barrel to reach a certain degree, lead to outside hay can not continue to get into the sampler barrel again, lead to the sampler barrel can not continue to change again, sample head end portion can not continue to cut the hay again, but the electric drill is still rotating work, this just leads to easily causing the motion state inconsistency between electric drill and the sampler barrel, the two is the separation of releasing easily, can not continue to sample.
