Sampling device

Abstract

The invention discloses a sampling device. The sampling device comprises a guiding framework, a vibrating framework and a sampling rod component which are arranged up and down, wherein a sampling driving component is arranged in the guiding framework; the upper end of the sampling rod component penetrates through the vibrating framework and then is connected with the sampling driving component soas to drive sampling; a vibrating component is arranged in the vibrating framework and is used for enabling the sampling rod component to generate vibration; and the bottom end of the framework is connected with the top end of the vibrating framework through a plurality of vibration reduction connecting components so as to form buffer vibration reduction. The sampling device disclosed by the invention has the advantages of simple and compact structure, good sampling effect, good vibration reducing effect, long service life and capability of ensuring representativeness and authenticity of a sample.

Description

technical field [0001] The invention mainly relates to the field of sampling equipment for material samples, in particular to a sampling device. Background technique [0002] For the sampling, sample preparation, and testing of material (such as ore, coal) samples, each country has mandatory standards, and the sampling and processing of samples must be carried out in accordance with the standards. The principle of sample sampling, sample preparation, and testing work process is to gradually reduce the particle size and quality of the collected samples without destroying the representativeness of the sample, until it meets the particle size and quality of the sample in the laboratory test ( Weight) accuracy requirements, and then carry out relevant laboratory analysis on the samples that meet the requirements. [0003] For example, taking coal sampling as an example, it is actually a sampling and analysis process. The purpose of coal sampling and sample preparation is to obt...

Problems solved by technology

[0005] (1) After the sampling rod of the existing sampling device is inserted into the stockpile for sampling and pulled out, it is easy to bring out some residual materials that are not required for collection. This is easy to cause ash and coal, which is not environmentally friendly; Sampling with subsequent batches will cause mixed samples, which will seriously affect the accuracy requirements of subsequent sampling and production

However, if a vibration mechanism is installed for vibration, the vibration source will seriously affect the coordination accuracy and service life of the sampling rod itself, the sampling rod driving device, and the sampling rod lifting device, which will not only increase the risk of subsequent operations, but also increase the use cost of the equipment

[0006] (2) When the existing sampling device is lifting and sampling, due to the high density of the material, the position of the sampling rod is prone to misalignment, resulting in inaccurate sampling, and even damage to the sampling rod or sampling head in severe cases

[0007] (3) The structure of the lifting system of the existing sampling device is complicated, and there are a series of problems such as unstable transmission and unbalanced force

[0008] (4) The structure design of the sampling rod of the existing sampling device is not firm, and it is easy to bend and deform due to force overload when inserting and sampling

And part of the sampling head has complex structure, not only easy to take out excess material, but also difficult to insert into the stockpile, affecting the effect of deep sampling
