Problems solved by technology

[0004] Through research on the prior art, the applicant found that in the above application documents, when the crucible carrying the sample is transferred to the furnace mouth, the chain with chain plate mechanism is used for transmission, and there are the following problems: 1. The chain with chain plate mechanism is composed of at least two Composed of two chains and multiple chain plates, there are many parts, and it is difficult to install and maintain
2. Due to the high temperature at the furnace mouth and the chain itself, the chain is prone to deformation and elongation after working for a long time, resulting in low positioning accuracy during transmission and prone to errors, thus affecting the experimental results
3. The combustion tube of the high-temperature furnace is circular, and the bracket for conveying the crucible is a flat plate. When a large number of crucibles are fed into or pulled out of the combustion tube from the bracket, it is easy to deflect the crucible, causing the crucible to be stuck in the furnace mouth, affecting Analysis speed

Abstract

The invention discloses an automatic sample conveying device, which comprises a support frame, a mesh-belt conveying mechanism, a lead-screw conveying mechanism, a push rod mechanism and a furnace opening guide block, wherein the mesh-belt conveying mechanism is arranged on the support frame and is used for placing crucible pots and conveying the crucible pots in batches, the lead-screw conveyingmechanism is arranged on the support frame, and is used for conveying the crucible pots conveyed by the mesh-belt conveying mechanism to a stokehole, the push rod mechanism is arranged on the supportframe, is used for pushing the crucible pots conveyed to the stokehole by the lead-screw conveying mechanism into a furnace cavity, and can pull out the crucible pots out of the furnace cavity, and the furnace opening guide block is arranged at the stokehole and is used for making the push rod mechanism smooth push the crucible pots into the furnace cavity or smoothly pull out the crucible pots. The automatic sample conveying device can automatically control the sample conveyance in batches, the whole process is completely automatic without manual operation, and the labor can be saved. In addition, the conveyance precision is high, and the personal error is reduced.

Description

technical field [0001] The present application relates to the field of coal quality analysis instruments, in particular to an automatic sample feeding device for coal quality analysis instruments. Background technique [0002] In the series of coal quality analysis instruments, in order to measure the content of sulfur and other substances in the combustibles, the crucible carrying the combustibles is often accurately placed in the high-temperature constant temperature zone of the silicon carbon furnace, and the combustibles are burned. And through infrared light to measure the content index of sulfur or other substances. This infrared light sulfur meter is used to measure the sulfur content in combustibles, and has the advantages of accuracy and speed. [0003] Due to the high labor intensity and slow speed of manual sample delivery, the possibility of stakeout errors is relatively high, and the speed of manual sample delivery is inconsistent, resulting in inconsistent tim...
