Description

Drilling granary sampler and grain pile sampling and image recording method thereof Technical Field The invention belongs to the field of agricultural product storage, and particularly relates to a drilling granary sampler and a grain pile sampling and image recording method thereof. Background The quality inspection of grains is important in the links of warehousing, ex-warehouse and the like, and the sampling is the key first step of acquiring inspection samples. The drill-in sampler is a deep sampling device commonly used in grain depots and generally comprises a drill bit, a drill rod, a driving mechanism and a sample bin. When the device works, the drill bit rotates to drill into the grain pile, and after the drill bit reaches a preset depth, the sample bin door is opened through the mechanical device, so that grains flow into the sample bin, and sampling is completed. However, in the prior art, the whole sampling process is completely performed outside the sight of an operator, the operator cannot observe the drilling state of the drill bit in the grain pile and the visual conditions of the quality of surrounding grains, if the abnormal conditions such as local mildew, caking and insect attack exist, and whether the sample bin gate is smoothly opened and closed at the correct position cannot be confirmed. This blind sampling approach results in whether the sample actually represents grain conditions at the target location, particularly in local areas where quality differences may exist, is entirely dependent on operator experience and contingency of the equipment operation, sample representativeness is difficult to ensure, directly affects the accuracy of subsequent test results, and once a dispute is made about the sample representativeness or sampling process due to lack of process records, for example, the sample is suspected to be contaminated with upper layer impurities or not taken from a predetermined depth, lack of objective image evidence for traceability and verification, presents difficulties in quality management and definition of responsibility. Although the camera device is tried to be introduced in the individual technical exploration, the camera device is simply arranged at the front end of the equipment or is coaxially arranged with the drill bit, so that the camera device is easy to be blocked by grains in the drilling process and is invalid, the conditions of the side of the drill bit and the working area of the sample bin are difficult to effectively observe from the visual angle, and the core problems of invisible and non-traceable sampling process cannot be fundamentally solved. Disclosure of Invention In view of the above, the present invention is directed to a drilling-in granary sampler and a grain pile sampling and image recording method thereof, so as to solve the problems of invisible sampling process, insufficient sample representativeness and difficult process tracing of the drilling-in granary sampler.
