Description
Technical Field
The utility model relates to the technical field of sampling equipment, in particular to a full-section arbitrary depth quantitative sampler.
Background
At present, deep samplers used for mechanical sampling of bulk solid minerals such as coal, iron ore and the like include an internal screw auger type and an external screw claw type. The internal spiral drilling type high-speed rotating spiral drill bit can perform indiscriminate crushing on large-particle-size coal samples, gangue or ores, however, some test items, such as particle size screening, crushing strength, mechanical strength, falling strength, compressive strength and the like, cannot damage the original particle size of the samples when sampling is required. In addition, the auger bit rotating at high speed can damage the bottom of the carriage, and for safety, the real full-section arbitrary depth sampling is difficult to realize in practical application. The above problems are solved by a new type of spiral sampler, CN201510181209.7 spiral sampler, such as the disclosed patent CN 201620845384.1.
The existing external spiral claw type sampling head has the advantages that conical claw sheets forming the sampling head rotate in a closed state to enter material layers (such as coal beds and iron ore layers), after the sampling head reaches a certain depth, the head claw sheets are forcibly opened in the material layers by a driving mechanism, the sampling head continues to move downwards, materials enter a sampling cylinder, and after a certain amount of materials are collected, the claw sheets are forcibly closed in the material layers through the driving mechanism, and sampling is completed. In the process, the original granularity of the material cannot be excessively damaged, but the conical claw piece needs to overcome the strong resistance of the material to the claw piece in the material layer twice in sequence to complete the opening and closing action, and the resistance of the material needs to be resisted to move to the deep layer, so that the reliability and the service life of the equipment are greatly influenced. In the past, the claw sheet is easy to deform or damage, cannot be closed, and is difficult to realize material collection. The problems of the sampling machine manipulator device and the sampling machine disclosed in the patent publication CN201210181342.9, and the problems of the sampling device and the sampling head thereof disclosed in the patent publication CN201710651181.8 are all solved.
In summary, how to effectively overcome the problems in the prior art to realize real full-section arbitrary depth sampling without damaging the original particle size of the material is urgent to be solved by the technical personnel in the field.
The above information disclosed in this background section is only for enhancement of understanding of the background of the utility model and therefore it may contain information that does not form the prior art that is well known to those of ordinary skill in the art.
