Hay sampling device

Abstract

The invention discloses a hay sampling device which comprises an electric drill, a sampling barrel and a drill rod, the drill rod is detachably arranged on the electric drill, and the electric drill can drive the drill rod to rotate; the drill rod comprises a tip part, a shaft rod and a spiral conveying part, the tip part is arranged at one end of the shaft rod, the spiral conveying part spirally extends in the axial direction of the shaft rod, the sampling barrel comprises a barrel body and a plurality of fixing sharp feet, a first opening, a second opening and a discharging port are formed in the barrel body, and the fixing sharp feet are arranged on the first opening side of the barrel body; the drill rod tip part, the shaft rod and the spiral conveying part can penetrate through the barrel and the first opening through the second opening, the second opening is connected with the guide sleeve, and the guide sleeve is arranged in the barrel. The hay sampling device is high in sampling speed and large in single sampling amount, hay samples are easy to collect and not prone to leaking and scattering, and operation is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of feed sampling and detection, in particular to a hay sampling device. Background technique [0002] At present, the hay bale production technology in animal husbandry production is becoming more and more mature, and it is also becoming more and more large-scale, so the correct sampling of hay and the evaluation of its nutritional value are extremely important. But, only have the sampler of grain and concentrate feed on the market now, its production and processing technology is mature, the production of roughage sampler especially hay sampler is almost blank. Most of the hay sampling can only be done manually, which is time-consuming and labor-intensive, destroying the structure of the bale, and the samples are not representative, and due to the high density of the hay bale, the common manual hay sampler generally requires a lot of effort to use. To complete the sampling, it is extremely difficult for fem...

Problems solved by technology

However, there are only grain and concentrated feed samplers on the market now, and its production and processing technology is mature. The production of roughage samplers, especially hay samplers, is almost blank.

Most of the hay sampling can only be done manually, which is time-consuming and labor-intensive, destroying the structure of the bale, and the samples are not representative, and due to the high density of the hay bale, the common manual hay sampler generally requires a lot of effort to use. To complete the sampling, it is extremely difficult for female samplers with less strength; there are also electric and imported hay samplers on the market, but they all exist or the sampling speed is slow; or the sampling volume is small and requires multiple times Repeated sampling to reach the required test sample weight; or directly stuck in the sampling tube / sampler after sampling, which cannot be packaged quickly and affects the moisture test results; or partly stuck in the sampling tube / sampler and transferred by the sampling tube / sampler The sample is still easy to leak when it arrives in the storage bag, resulting in incomplete collection of samples and affecting the test results

[0003] Chinese patent CN202547972U discloses a new type of electric hay sampler, which greatly speeds up the sampling process and reduces human factors, but because the diameter of the sampling cylinder of the sampler is relatively small, it often causes hay to be sampled. The hay sample is not easy to be unloaded, and a little carelessness will easily lead to the leakage of the sampled hay sample, resulting in incomplete collection of samples and affecting the test results; in addition, usually in the sampling process of the hay sampler with this structure The internal space of the cylinder is limited, and the hay is easily compacted after continuously entering the sampling cylinder, and the longer the electric drill works, the more the hay enters the sampling cylinder, the greater the degree of compaction of the hay, and the more laborious the further sampling will be. To a certain extent, the hay in the sampling cylinder will be stuck in the sampling cylinder, causing the external hay to no longer enter the sampling cylinder, causing the sampling cylinder to stop turning, and the end of the sampling head to cut the hay no longer, but the electric drill is still Rotation work, which will easily lead to inconsistency between the electric drill and the sampling cylinder, the two are easy to trip and separate, and it is impossible to continue sampling
