Abstract

The invention belongs to the technical field of sample collection, and discloses a falling flow sampling device which comprises a rectifying tube, a sample collecting tube, a rejected sample collecting hopper and a division plate, the sample collecting tube and the rectifying tube are coaxially arranged and form a sample collecting channel, and a sample reserving container is arranged right opposite to the lower end of the sample collecting tube; the rejected sample collecting hopper is axially parallel to the rectifying tube and located between the rectifying tube and the reserved sample container, the sample collecting tube penetrates through the side wall of the rejected sample collecting hopper, the rejected sample container is arranged right opposite to the lower end of the rejected sample collecting hopper, the division plate is arranged between the rectifying tube and the sample collecting tube, a mounting hole is formed in the division plate, and a sample intercepting tube is inserted into the mounting hole. The division plate can swing in a reciprocating mode in the axial direction of the abandoned sample collecting hopper so as to open and close the sample collecting channel, and the swing speed of the division plate can be set to be adjustable. According to the falling flow sampling device, the use compatibility can be effectively improved, and the reliability and effectiveness of sample collection are guaranteed.

Description

technical field [0001] The invention relates to the technical field of sample collection, in particular to a downflow sampling device. Background technique [0002] At present, samples such as coal need to be sampled in the process of running and falling to test the quality of the samples such as coal. Most of the drop-flow sampling devices in the prior art are provided with a subdivision disc with a number of through holes. Under the driving action of the driving device, the subdivision disc will rotate relative to the sample container, and then fall down from the top of the subdivision disc. The sample flows and falls onto the subdivision plate. During the rotation of the subdivision plate relative to the sample container, when the through hole on the subdivision plate rotates to the position opposite to the opening of the sample container, Part of the sample can fall into the sample container through the through hole, and the rest of the samples on the shrinking tray wil...
