Description

Technical Field

[0001] The invention belongs to the technical field of grain storage, and in particular relates to a sampler for grain storage detection. Background Art

[0002] When storing grain, it is necessary to regularly sample and test the grain to test its water absorption, fatty acid value, oil oxidation value, etc., to evaluate the state of the grain in the warehouse. Common grain samplers are usually a stainless steel tube with a sharp top and an opening. When pierced, the grain falls from the opening, or a hole is opened in the side wall of the sampling tube for the pierced grain to fall into, so as to achieve sampling.

[0003] The Chinese patent with the publication number CN219810700U discloses a stored grain sampler, including an external sampling tube and a driving unit, wherein the lower end of the inner part of the external sampling tube is rotatably connected to a support plate through a bearing, an inner sampling tube is arranged on the upper surface of the support plate, a housing is arranged on the upper end of the outer arc surface of the external sampling tube, a hammer ring is movably sleeved on the upper end of the outer arc surface of the external sampling tube, and the hammer ring is located inside the housing; the driving unit is arranged in the middle of the housing, the hammer ring is arranged in coordination with the driving unit, a uniformly distributed baffle is arranged inside the internal sampling tube, a handle 1 is symmetrically arranged on the upper end of the outer arc surface of the external sampling tube, a handle 2 is arranged on the upper end of the internal sampling tube, and a positioning frame is arranged on the upper end of the external sampling tube. The stored grain sampler has high sampling efficiency, saves time and labor, and the positioning of the internal sampling tube is convenient, so that layered sampling can be realized. However, the outer sampling tube of the device is integrally formed and its length cannot be adjusted. If it is too short, the sampling depth is limited. If it is too long, it is not easy for the testers to carry it around. It is also not easy to store and preserve after use. It is also inconvenient to use. When sampling, it is not easy for food to enter the inner sampling tube, and effective sampling cannot be performed. In addition, when the sampling is completed and the sample needs to be taken out from the device, samples of different layers are easily mixed together, affecting the test results, which greatly limits the applicability of the device.
