Problems solved by technology

[0004] However, the lofting carousel of the existing automatic sample feeding device is solid. At the same time, due to the large diameter of the lofting carousel, it takes up a large space and cannot be used, which further leads to other components such as telescopic manipulators used in conjunction with the lofting carousel. It must be set above or below the stakeout turntable, resulting in an uncompact structure of the automatic sample feeding device, and the total occupied space is extremely large

Embodiment 1

[0035] Such as Figure 4 As shown, the hollow turntable sample delivery device provided by Embodiment 1 of the present invention includes a ring-shaped stakeout table 1, a transmission assembly 2, a drive assembly 3, a guide assembly 4, a mounting plate 5, a retractable manipulator 6, a control assembly 7, Indexing component 8 and lifting component 9.

[0036] Such as Figure 5 As shown, the annular lofting table 1 is uniformly provided with a number of sample positioning through grooves 11 along the circumferential direction; the transmission assembly 2 includes a first transmission member 21 and a second transmission member 22, the first transmission member 21 and the second transmission member 21 The second transmission member 22 is a belt pulley, the first transmission member 21 and the second transmission member 22 are rotationally connected by a belt, and the outer diameter of the first transmission member 21 is larger than the outer diameter of the second transmission membe...

Embodiment 2

[0042] The hollow turntable sample feeding device provided in the second embodiment of the present invention is similar to that in the first embodiment, except that the transmission assembly 2 includes a first transmission member 21 and a second transmission member 22. The first transmission member 21 and the second transmission member 22 are a pair of gears that mesh with each other, and the outer diameter of the first transmission member 21 is larger than the outer diameter of the second transmission member 22; the lifting assembly 9 is a miniature hydraulic cylinder, arranged in the ring The shape lofting table 1 is directly below the telescopic direction of the telescopic manipulator 6.

[0043] The working process of the hollow turntable sample delivery device provided in Embodiment 2 of the present invention is similar to that in Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a hollow turntable type sample delivery device, which comprises an annular sample placement platform, a transmission component, a driving component, a guide component and a mounting plate, wherein the transmission component comprises a first transmission part and a second transmission part, the driving component is fixedly connected with the mounting plate, and is in driving connection with the second transmission part, the guide component comprises an annular guide rail and at least three guide wheels fixedly arranged on the end face of the mounting plate, the annular guide rail is connected with the guide wheels in a rotating manner, and the annular sample placement platform, the first transmission part and the annular guide rail are coaxially and fixedly connected. According to the device, the annular sample placement platform is adopted instead of a conventional solid disc-shaped sample placement turntable, and another component such as a telescopic mechanical hand can be arranged in an inner hole of the annular sample placement platform, so that the space of the inner hole is effectively utilized, the structure is compact and reasonable in design, and the device is integrated and systematic, and has a broad application prospect.

Description

Technical field [0001] The present invention relates to the technical field of coal quality analysis, and more specifically, to a hollow turntable sample delivery device. Background technique [0002] In the current field of coal quality analysis technology, a test method is often used. It is necessary to put a coal sample in a high-temperature furnace for combustion, and then collect the combusted gas for analysis. In the current various automatic sample feeding technologies, the automatic sample feeding device is mainly used to send the crucible containing the coal sample into the combustion furnace for combustion. After the combustion is completed, the crucible is taken out, and then the above process is repeated to achieve automatic sample feeding. the goal of. [0003] Such as Figure 1-3 As shown, most of the currently used automatic sample feeding devices directly or indirectly drive the lofting turntable to rotate through the drive assembly, and at the same time, control th...
