Abstract

The invention discloses a grabbing type sampling device, which comprises a driving device, an inner transmission shaft, an inner pulling shaft, an outer barrel, a sampling barrel and a claw; the output shaft of the driving device is provided with an input gear; the inner transmission shaft is provided with an inner transmission shaft input gear meshed with the input gear and is further provided with an inner transmission shaft output gear; one end of the inner pulling shaft is provided with an inner pulling shaft input gear that is axially limited and meshed with the inner transmission shaft output gear while the other end of the inner pulling shaft is provided with a plurality of racks; the inner pulling shaft input gear is matched with the inner pulling shaft by screw threads; the outerbarrel is sleeved at the outer side of the inner pulling shaft; the sampling barrel is arranged at the lower end of the outer barrel; the rack extends into the sampling barrel; the claw can be arranged on the sampling barrel in rotatable manner; the number of the claws is the same with that of the racks; and the claw is provided with a turning gear meshed with the rack. The grabbing type samplingdevice provided by the invention solves the problem that the helical sampling device cannot collect high-density or low-density materials, such as pellet, sawdust and the like.

Description

technical field [0001] The invention relates to the technical field of sampling machines, in particular to a grasping sampling device. Background technique [0002] Sampling machines (auto-sampling machines) can be divided into many types according to the structure and application occasions, such as carriage (car, train) sampling machines, pipeline sampling machines, belt sampling machines (head, middle) and so on. It is generally used for sampling during the transportation and transshipment of bulk materials (such as coal, ore, grain, etc.). Such equipment is generally designed and used in a complete set according to the site conditions, and is usually composed of a sampling machine, sample conveying equipment, crushing equipment, shrinking equipment, waste material processing equipment, and an electronic control system. [0003] At present, there are many types of sampling devices used in various sampling machines produced in China. The commonly used sampling methods are:...
