Crucible

Abstract

The invention discloses a crucible which comprises a crucible main body, and at least two spacing bodies axially distributed along the crucible main body are arranged on the crucible main body. For the crucible provided by the invention, at least two spacing bodies are arranged on the crucible main body so as to ensure that a mechanical claw can be spaced through one of the spacing bodies to clamp the crucible, and the other spacing body is used as a spacing component for clamping the crucible on a sample placing disc. The crucible provided by the invention can be applicable to horizontal clamping, the problems of smoothness and reliability in movement can be solved through the spacing of the two spacing bodies, sample rejection turning can be realized, an automatic instrument mechanism can be simplified, and the crucible is beneficial to increasing mechanism strength and reducing instrument size and is economical and applicable.

Description

technical field [0001] The invention relates to the technical field of coal quality analysis instruments, in particular to a crucible. Background technique [0002] In the prior art, the automation of many testing instruments is getting higher and higher. It only needs to put the empty crucible into the sample tray, and the rest is all done by the computer, including the crucible taking, moving, flipping and discarding the sample, etc. Automate. In the prior art, for the clamping and moving of the crucible, the method used is as follows: figure 1 , figure 2 , image 3 , Figure 4 Several forms are shown. [0003] in, figure 1 Shown is directly lifting the crucible, figure 1 In this way, if there is a deviation between the center of the lifting rod 2 and the center of the crucible 1, it is easy to tilt and fall, and during the movement of the crucible 1, the requirements for the stability of the movement are high, and a slight shaking can easily cause the crucible 1 t...

AI Technical Summary

Problems solved by technology

In this way, the processing requirements of the crucible are improved, and the crucible 1 itself is a ceramic part, which increases the difficulty and cost of manufacturing the crucible.

At the same time, the crucible needs to participate in the combustion process, which will cause deformation and affect the positioning surface, resulting in poor positioning and causing failures

The above content is only in the fetching and moving action of the crucible 1. If the sample needs to be flipped and discarded, judging from the current crucible 1, the above situation cannot be realized.

From this point of view, the crucible in the current technology is difficult to meet the requirements of the improvement of instrument automation.

Either the mechanism of the instrument is complicated, the volume is increased, the strength is weakened, the reliability is reduced, and the space is consumed, or the manufacturing difficulty of the crucible itself is increased and the cost is increased.
