Abstract

The invention discloses an automatic powder feeding device for analytical instruments. The device comprises a lofting mechanism used for storing and providing a sample, a sample weighing mechanism used for receiving a sample from the lofting mechanism and weighing the sample, wherein a sample leaking hole used for falling of the sample is formed in the bottom of the lofting mechanism; the sample weighing mechanism is provided with a sample weighing container of which the opening is formed upward; the sample leaking hole and the opening of the sample weighing container are distributed in an up-down corresponding manner; the lofting mechanism is provided with a sample falling control mechanism for controlling the sample falling amount; and the sample falling control mechanism is used for controlling the falling amount of samples falling from the sample leaking hole by opening and closing the sample leaking hole. The device can be used for accurately controlling obtained samples.

Description

technical field [0001] The invention relates to the field of industrial analysis equipment, in particular to a powder automatic sampling device for analysis equipment. Background technique [0002] During the use of automatic analysis instruments, it is often necessary to place the sample amount in the crucible on the turntable for burning. A certain weight of sample needs to be added to each crucible, and different weights need to be added to the sample for different analyzes samples, and it is possible that the types of samples added are completely different. [0003] At present, our method of adding samples is to add samples manually. After adding one sample, add the next sample. The weight of the sample added manually is difficult to control, and the weight varies greatly; and the type of sample added is very easy. Something went wrong. Therefore, the existing manual sample addition method mainly has the following disadvantages: 1. It is easy to add the wrong sample, a...
