Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, and reference
Attached drawing, the present invention is described in more detail.
First embodiment:
In the present embodiment, a kind of adjustable full-automatic sample injector for varying position is provided.As shown in Figure 1, the present invention is adjustable
The full-automatic sample injector for varying position includes: disk body 10, N number of hole location 70, N number of telescopic rod 20, sample running track 30, electromagnetic power
System 40 and a rotation axis 50.
N number of arrangement of hole location 70 forms two injection annulus, is divided into the first ring and the second ring, and all hole locations are located at same put down
On face, such as each injection annulus has 80 hole locations, and what the stain in Fig. 1 represented is unillustrated hole location, is filled in hole location 70
There is sample, when hole location 70 rotates in sample running track 30, the sample in hole location 70, which is admitted in elemental analyser, to be carried out
Elemental analysis.One end of telescopic rod 20 is connect with rotation axis 50, and the other end is fixedly connected with a hole location 70, and telescopic rod 20, which surrounds, to be turned
The rotation of hole location 70 is driven when moving axis 50 rotates；Under the action of electromagnetic power system 40, realize hole location 70 in sample position and sample
Switching between running track 30, also, all hole locations 70 of the first ring are located at respective sample position or sample running track simultaneously
30, all hole locations 70 of the second ring are located at respective sample position or sample running track 30 simultaneously.As hole location 70 in the first ring
When in sample running track 30, the hole location 70 of the second ring is located on respective sample position；When the hole location 70 of the second ring is located at sample
When in running track 30, the hole location 70 of the first ring is located on respective sample position.
Disk body 10 can be column structure, for carrying electromagnetic power system 40.
Electromagnetic power system 40 includes 2N electromagnetic coil 60, solenoid valve and controller, and every 2 electromagnetic coils 60 are located at
In one telescopic rod 20, the hole location 70 of the first ring of solenoid valve control or the hole location 70 of the second ring are stretched or are shunk simultaneously, control
The operation of device control electromagnetic power system 40 processed.
It should be noted that two electromagnetic coils 60 in each telescopic rod 20 are oppositely arranged, i.e. two electromagnetic wires
