Automatic sampling and reducing device for limestone belt conveyor

Abstract

The invention relates to an automatic sampling and reducing device for a limestone belt conveyor. The automatic sampling and reducing device comprises a belt conveyor, and an electric-control cabinet,and further comprises an automatic sampling unit and an automatic reducing unit, wherein the machine head of the belt conveyor is equipped with an unloading scraper-trough conveyer on a transfer station bracket of the belt conveyor; a material receiving belt is arranged below a discharge hole of the unloading scraper-trough conveyor; the automatic sampling unit comprises a first electric-hydraulic pushing rod pedestal, a first electric-hydraulic pushing rod and a turnover hopper; a feeding pipeline is arranged on the transfer station bracket of the belt conveyor; an upper-end charge hole of the feeding pipeline is formed in the lower portion of the turnover hopper; the automatic reducing unit is arranged below a lower-end discharge hole of the feeding pipeline; and the automatic reducingunit comprises a material collecting hopper, a second electric-hydraulic pushing rod pedestal, a second electric-hydraulic pushing rod, a sample separator, a sample box and a waste tank. The automaticsampling and reducing device is simple in structure, improves sampling and working efficiency, saves manpower and material resources, eliminates safety risk, and realizes automatic sampling and automatic reducing for large-particle-diameter materials.

Description

technical field [0001] The invention relates to a limestone belt conveyor, in particular to an automatic sampling and shrinking device for a limestone belt conveyor. Background technique [0002] The particle size of the limestone belt material is generally <70mm, which is a large particle size material. At present, samples are taken manually on the running belt once an hour. This sampling method not only has a large safety risk, but also cannot achieve high-frequency sampling. The representativeness is extremely poor, and it is impossible to guide the production matching. The belt automatic sampling system in this field is generally a powder material sampler, which cannot be applied to the automatic sampling of large particle size materials, and cannot automatically shrink the sample. Contents of the invention [0003] The present invention aims to solve the above problems, thereby providing an automatic sampling and shrinking device for a limestone belt conveyor that ...
