Description

Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to a modular particle sampler. Background Art

[0002] Sampling, that is, taking a few samples from a large number of items or materials, is widely used, for example, in grain storage, chemical industry, petroleum and other fields. The purpose of sampling is to characterize the performance of the entire product by testing the performance of a small number of samples. Therefore, whether the sample has the characteristics that represent the entire product will play a very important role in the characterization of the entire product. Whether the sampling is uniform is an important factor affecting the correct characterization of the characteristics of the item. When a large number of solid products such as particles and powders are piled together, if the sample obtained only comes from the upper layer, the sample can only represent the upper layer. Using this sample to characterize the entire product will produce wrong conclusions. If the sampling is uneven, the unqualified products will be used in industries and other fields, which will lead to serious consequences. Therefore, people have designed various types of material sampling devices.

[0003] For example, the utility model with patent number CN204405365U discloses a sampling device, including an inner tube and an outer tube; a plurality of inner sampling holes are sequentially arranged on the side wall of the inner tube along the direction in which the inner tube extends; the outer tube is a hollow shell with an open end; a plurality of outer sampling holes are sequentially arranged on the side wall of the outer tube along the direction in which the outer tube extends; the outer tube is sleeved outside the inner tube so that the inner tube can rotate relative to the outer tube.

[0004] There are at least the following problems in the above patent: first, when sampling is performed by aligning the inner sampling hole and the outer sampling hole, the samples of the upper, middle and lower layers will enter the inner tube from each sampling hole at the same time and fall down to accumulate, which will cause the samples to mix during the accumulation process; second, after the samples in the inner tube are poured out, the mixing situation will be further aggravated, and the internal situation of the material cannot be effectively analyzed. Utility Model Content

[0005] The utility model aims at the deficiencies of the prior art and develops a modular particle sampler. The utility model can sample materials in each layer separately and prevent the samples from mixing when being poured out, thereby effectively improving the effectiveness of sampling and facilitating people's analysis of samples.

[0006] The technical solution of the utility model to solve the technical problem is: a modular particle sampler, including an inner rod and an outer tube, the inner end of the inner rod is sleeved inside the outer tube, one side of the outer tube is provided with a plurality of groups of sampling windows, one side of the inner rod is provided with a plurality of groups of mounting grooves matching the sampling windows, a sampling module is detachably provided in the mounting groove, one side of the sampling module is provided with a sampling groove, and the other side of the sampling module is connected to the mounting groove through a connecting piece.

[0007] As an optimization, a track groove is provided on the side wall of one end of the outer tube, and the end of the other end of the outer tube is conical, and one end of the track groove corresponds to the sampling window. By providing the track groove, the inner rod can be easily rotated; by providing the conical end, the outer tube can be easily inserted into the material, and by providing one end of the track groove corresponding to the sampling window, it is convenient to locate and sample.

[0008] As an optimization, a handle is provided at the outer end of the inner rod, and a limit bolt matching the track groove is provided on the rod body of the inner rod. The limit bolt is detachably arranged on one side of the inner rod, and the limit bolt corresponds to the installation groove. By setting the handle, the inner rod can be easily rotated and pulled out for sampling and changing molds; by detachably setting the limit bolt, the inner rod can be easily inserted, and the limit bolt can match the track groove. When the inner rod is rotated until the limit bolt presses against one end of the track groove, the sampling slots of each sampling module can be aligned with each sampling window one by one, so that sufficient sampling can be performed, and the inner rod can be prevented from axially moving in the outer tube, and the outer tube can be taken out after sampling.

[0009] As an optimization, the sampling slot is set in the middle of one side of the sampling module, and a capacity mark is set on the sampling module. The width of the sampling slot is less than or equal to the width of the sampling window, and the length of the sampling slot is less than or equal to the length of the sampling window. By setting the capacity mark, a suitable sampling module can be quickly found for installation according to sampling requirements.

[0010] As an optimization, the connecting piece includes a magnet and an iron sheet, which are respectively arranged at the bottom of the sampling module and the bottom of the mounting groove. By arranging the magnet and the iron sheet, the sampling module can be prevented from accidentally falling out of the mounting groove, and the sampling module will not be poured out when pouring out the sample, and the separation and mold replacement can be convenient.
