Technical Field

The invention relates to the field of solid sample or material conveying, in particular to a chain plate type material continuous conveying and lifting device.

Background

The vertical or elevation continuous conveying and conveying equipment for solid samples or materials is indispensable process equipment in the field of on-line sampling and detection of bulk and bulk mineral products. The vertical or elevation continuous conveying and transmission of small-batch (conveying capacity:lessthan or equal to 20T/h) bulk cargo materials is realized by generally crushing and dividing all stages of waste samples in an online sampling detection system, collecting the waste samples into a sample discarding point or a sample discarding channel through a sample discarding transfer belt conveyor or/and a sample discarding chute in the system, and then carrying out batch or continuous lifting and transmission on the samples through corresponding lifting equipment and returning the samples to an initial main system conveying line. For example, for an on-line sample collection and preparation system of a professional coal bulk port wharf, sample collection and preparation system equipment is usually selected to be built under a corridor of a port area conveyor belt, a first-level sampler of the system enters the system after collecting a sample, and the sample is subjected to sample preparation treatment such as crushing, division and the like, and a waste sample generated in the treatment process needs to be transported back to the corresponding port area conveyor belt above the sample preparation system.

At present, abandoned samples generated in the sample preparation process of the on-line sample preparation system of each professional coal bulk port wharf are returned mainly by a circulating hopper type lifter or by a steel wire traction type single hopper lifter. The traditional circulating hopper type elevator has the defects that equipment is easy to block the bottom of a hopper bin when meeting the lifting working condition of coal slime materials, and once the bottom of the hopper bin is blocked, the maintenance and cleaning work is very complicated; the steel wire traction type single-bucket elevator has the defects that discontinuous material lifting transportation is performed, before the material transportation bucket does not return to the position of the material receiving zero point at the bottom, sample abandoning transportation equipment generated by a sample preparation system can continue to operate after the transportation bucket returns to the zero point, and the operating efficiency of the sample preparation system is necessarily influenced by the discontinuous operating working condition.
