Automatic feeding equipment for samples

Abstract

The invention discloses automatic feeding equipment for samples. The automatic feeding equipment comprises a conveyor line device for conveying the sample barrels. An uncovering unlocking device and apouring manipulator device are sequentially arranged above the conveyor line device, and the pouring manipulator device comprises a clamping overturning manipulator and a pouring conveyor line. The sample barrels are conveyed to the position below the uncovering unlocking device in the forward direction, unlocked and uncovered and then continuously conveyed to the position below the pouring manipulator device in the forward direction. The clamping overturning manipulator is used for clamping the sample barrels and driving the sample barrels to be conveyed to a feeding station in the forward direction under driving of the pouring conveyor line to enable the sample barrels to be overturned at the feeding station to complete pouring unloading. After pouring unloading is completed, the samplebarrels are driven by the clamping overturning manipulator to be conveyed to the conveyor line device in the reverse direction, covered through the uncovering unlocking device, and then conveyed through the conveyor line device in the reverse direction. The automatic feeding equipment has the advantages that the automatic and intelligent degrees are high, safety is high, the manual labor intensity can be relieved, and work continuity is kept.

Description

technical field [0001] The invention mainly relates to the field of material sample collection and analysis equipment, in particular to an automatic feeding equipment for samples. Background technique [0002] For the sampling and analysis of materials (such as ore and coal), each country has mandatory standards, and sampling and analysis must be carried out in accordance with the standards. The principle of the sample collection and analysis process is to gradually reduce the particle size and quality of the collected samples on the premise of not destroying the representativeness of the samples, until the particle size and mass (weight) accuracy requirements of the laboratory test are met. , and then carry out relevant test analysis on samples that meet the requirements. During this process, there can be no loss of samples, and no physical or chemical changes can occur in the samples, otherwise the final test results will be affected. [0003] Take coal material analysis...

AI Technical Summary

Problems solved by technology

[0005] (1) The degree of automation is not high, and it cannot meet the unattended operation requirements in the sample collection system

The loading and transferring of coal samples is usually manual handling and manual feeding, which is labor-intensive and low-efficiency, and the operation of the equipment is unstable due to irregular operations, which affects the overall operation of the system

[0006] (2) poor security

Due to the need to manually unlock and pour the material, there is a risk of artificial sample change, sample bucket falling and sample spilling

[0007] (3) Low degree of intelligence

When the sample barrel is finished emptying, it cannot be immediately transferred to the working station for the next batch of reloading, making it necessary to prepare a lot of sample barrels to meet the development of the system. Not only is the cost high, the work efficiency is low, and it cannot be quickly Well meet the requirements of continuous operation and efficient operation of the sample collection and preparation automation system

[0008] (4) Serious environmental pollution

Existing materials are easy to cause dust when unloading, which not only endangers the health of operators, but also is not conducive to environmental protection

[0009] (5) It is easy to cause sample contamination

The existing sample barrels cannot be cleaned automatically after loading. Manual cleaning is not only labor-intensive and low in work efficiency; but also manual cleaning is likely to cause mistakes and omissions, resulting in the residue of the current batch in the sample barrels and affecting the next batch of loaded samples. Accuracy and representativeness
