Abstract

The invention discloses a spiral sampling device. The spiral sampling device comprises a spiral outer barrel, a spiral sampling head arranged in the spiral outer barrel, a spiral blade arranged at the periphery of the spiral sampling head, a drilling bit fixed on the spiral sampling head, a splitting hole, a reserved sample hole, a material discarding pipe, a reserved sample cabin, a first driving device and a second driving device, wherein the splitting hole and the reserved sample hole, which are the same in size, are formed on the outer side of the spiral outer barrel at the same height, the reserved sample hole and the splitting hole are uniformly distributed along the circumference of the spiral outer barrel; and the material discarding pipe is connected with the splitting hole, and the reserved sample cabin is connected with the reserved sample hole. According to the spiral sampling device, the splitting hole and the reserved sample hole are formed at the same height of the spiral outer barrel, and the material can enter the splitting hole and the reserved sample hole randomly when positioned at the height; the splitting hole and the reserved sample hole are the same in size, and different materials can enter the splitting hole and the reserved sample hole randomly; and according to the spiral sample device, accurate splitting ratio can be provided and the sampling operation has randomness.

Description

technical field [0001] The invention relates to the technical field of sampling, more specifically, to a spiral sampler. Background technique [0002] The sampler is generally used for sampling during the transportation and transshipment of bulk materials, and it can collect samples from a batch of materials that can represent the batch of materials. At present, the samplers for mechanical sampling mainly include auger drill type, screw-in grab type and insertion grab type. As far as the auger sampler is concerned, it is generally provided with a reducer, which can reduce the sample amount during the sampling process and reduce the burden on subsequent sample preparation equipment. [0003] The existing spiral sampler is provided with a shrinkage port and a collection port, and part of the collected material enters the collection port and is used as a sample, and another part of the material is discharged from the shrinkage port as discarded material. In this spiral sample...
