When the third proximity switch in the sensing device receives a signal, the transverse stepper motor stops rotating, and at the same time, the lifting stepper motor starts to rotate. The rack meshes with the lifting gear, and the rack lifts the fixed push rod and lifting push plate. At the same time, the four lifting guide shafts in the flanged linear bearings fixed in the lifting motor bracket move upward, supporting the sample holder to the hopper claw in the predetermined hopper assembly. The lifting mechanism returns to the initial state, and at the same time, the transverse stepper motor in the transverse transmission mechanism reverses and pushes the pusher back to the initial position, and then performs the next automatic sample measurement action.

This achieves automatic sample delivery and automatic detection of the PIPS sample delivery mechanism of the present invention, solving the technical problem that existing PIPS sample delivery mechanisms generally only allow linear transmission, transmitting only one sample at a time, and detecting only one sample at a time, resulting in low detection efficiency of the low-background αβ counter due to the lack of an automatic sample delivery mechanism.

The control device 7 automatically controls the transverse transmission structure 2, the longitudinal transmission structure 4, and the lifting structure 3 along the "U"-shaped path. In this way, the PIPS sample delivery mechanism in this embodiment can automatically deliver samples and automatically detect them. This solves the technical problem that existing PIPS sample delivery mechanisms can only be used for linear transmission, and can only deliver one sample at a time. The detection process can only detect one sample at a time, and there is no automatic sample delivery mechanism, resulting in low detection efficiency of the low-background αβ counter.

After the second proximity switch 409 receives a signal, the longitudinal stepper motor 405 stops. In the transverse transmission mechanism, the transverse stepper motor 201 continues to rotate, and the pusher 209 pushes the sample holder 506 carrying the sample to the left to move to the lifting mechanism 3. When the third proximity switch 308 in the sensing device 6 receives a signal, the transverse stepper motor 201 stops rotating, and at the same time, the lifting stepper motor 305 starts to rotate. The rack 303 meshes with the lifting gear 304, and the rack 303 lifts the fixed push rod 306 and the lifting push plate 302. At the same time, the four lifting guide shafts 309 in the flanged linear bearing 310 fixed in the lifting motor bracket 301 move upward to lift the sample holder 506 to the hopper claw 505 in the predetermined hopper assembly 5. The lifting mechanism 3 falls back to the initial state, and at the same time, the transverse stepper motor 201 in the transverse transmission mechanism 2 reverses the pusher 209 back to the initial position, and then performs the next automatic sample measurement action.
