Description

Technical Field

[0001] The utility model relates to the technical field of material collection equipment, in particular to a flap type coal sampler. Background Art

[0002] In industries such as coal and cement, it is necessary to analyze the properties and quality of materials at each production stage in real time to achieve the purpose of quality control; therefore, every process from sampling, sample preparation to analysis is very important. Nowadays, the sampling process has evolved from traditional manual sampling to mechanical automated sampling, and its efficiency, accuracy, and timeliness have been greatly improved.

[0003] The Chinese patent "A Falling Flow Sampler" has the application number: 2023221339640, and the publication date is March 1, 2024. It discloses a discharge hopper, one side of which is provided with a material belt conveyor connected to the discharge hopper, and the other side of which is provided with a falling flow sampling assembly connected to the material belt conveyor. The falling flow sampling assembly includes an upper guide rail, a reduction motor is provided on the upper guide rail, a sampling trolley is provided between the reduction motor and the material belt conveyor, and is connected and fixed to the upper guide rail in a rolling manner, a crank is provided between the sampling trolley and the reduction motor, and a connecting rod is provided between the crank and the sampling trolley.
