The sample transfer device includes sample transfer cylinder, the spiral charging axle inside sample transfer cylinder, is installed on Sample transfer cylinder side connects the rotational handle for rotating in spiral charging axle, and the inlet port and outlet port set sample to pass respectively The both ends of defeated cylinder, the surface of the spiral charging axle are distributed with spiral helicine charging profile, and the axle body of the spiral charging axle from The respective side of feed inlet is gradually thicker to the respective side of discharge port, and the outside diameter of the charging profile on the axle body of spiral charging axle is protected Hold constant.

Preferably, the front end of the spiral charging axle is equipped with thrust rolling bearing, and rear end is equipped with charging axle rolling bearing, institute State rear end and be built-in with shaft coupling equipped with charging axle rolling bearing, the spiral charging axle docks a rotational handle by shaft coupling.

Preferably, the end of the close thrust rolling bearing of the spiral charging axle is equipped with check (non-return) valve.

Preferably, non-return valve is installed on the Sample buffer pipe.

Preferably, Non-return air valve and pressure-regulating valve are installed on the exhaust tube.

Preferably, the high pressure aspiration pump uses small-sized single cylinder high pressure aspiration pump, and the high pressure aspiration pump is fixed on institute State on sample transfer cylinder.

The operation principle of the utility model：High pressure pumping pump work starts to be evacuated, and when pumping passes through cyclone separator, and then Sample sipper tube can be allowed to draw sample for test particle, sample particle is fed to whirlwind together with the flowing of suction airflow In separator, cyclone separator carries out solid and gas separation to the air-flow of suction, and the air-flow after separation is carried out up by high pressure aspiration pump Take away, and sample particle then falls into following feed inlet, is entered by feed inlet in sample transfer cylinder, inside sample transfer cylinder Spiral charging axle in the operation of rotational handle, constantly by sample particle toward discharge port send out, due to spiral charging axle Gradually thicker structure, such sample particle is toward during discharge port flowing in sample transfer cylinder, and meeting is by the extruding of multiple multi-angle One piece is deposited in, can ensure the state extrusion discharge port for allowing sample particle mutually to compress during conveying.Such operational method it is good It is in and can be at the uniform velocity flowed out when the sample particle flowed out from discharge port.

Compared with prior art, the structure design characteristic of the utility model is to devise a sample transfer device and with one A sampling suction structure, it is therefore prevented that traditional method uses the work operations efficiency in a manner of artificial shovel takes low, great work intensity And doses it is uneven the problem of occur, in addition the design of whole equipment is simple, light-weight, easy to carry more convenient.

Brief description of the drawings

Fig. 1 is the structure diagram of the utility model.

Embodiment

Utility model is described in detail with reference to the accompanying drawings and examples.

As shown in Figure 1, the utility model proposes Portable sampling gun, including sample transfer device 1 and installed in sample pass Sampling suction structure 2 on defeated device, the both ends of sample transfer device 1 are respectively equipped with feed inlet 3 and discharge port 4, sample suction structure Be connected to feed inlet 3, the sampling suction structure include high pressure aspiration pump 5, connection be installed on feed inlet 3 on cyclone separator 6, Sample buffer pipe 7 installed in the input end of cyclone separator 6, the sample sipper tube 8 for being connected and installed in 7 front end of Sample buffer pipe, And the exhaust tube 9 of connection high pressure aspiration pump 5 and 6 exhaust end of cyclone separator, the discharge gate of 6 lower end of cyclone separator butt up against Feed inlet 3.To commonly use solid and gas separating component in the prior art, the small suitable carrying of cyclone separator 6 makes cyclone separator 6 With the discharge gate and feed inlet 3 of 6 lower end of cyclone separator are docked using ring flange, ensure that sealing.High pressure aspiration pump 5 Upper end be suction opening, side is exhaust outlet 16.The caliber of Sample buffer pipe 7 is more than the caliber of sample sipper tube 8, so designs It is advantageous in that the strong suction for ensureing sample sipper tube 8.

Sample transfer device 1 includes sample transfer cylinder 10, the spiral charging axle 11 inside sample transfer cylinder 10, installation In 3 side of sample transfer cylinder, connection rotates in the rotational handle 12 of spiral charging axle 11, and feed inlet 3 and discharge port 4 are set respectively Spiral helicine charging profile 13, and the spiral charging axle is distributed with the both ends of sample transfer cylinder 10, the surface of spiral charging axle 12 The respective side of 11 axle body from feed inlet 3 is gradually thicker to the respective side of discharge port 4, and the charging on the axle body of spiral charging axle The outside diameter of profile remains unchanged.The front end of spiral charging axle 11 is equipped with thrust rolling bearing 14, and rear end is equipped with charging axle rotation axis 15 are held, rear end is built-in with shaft coupling equipped with charging axle rolling bearing 15, and spiral charging axle 11 rotates hand by shaft coupling docking one Handle 16.The centre of rotational handle 12 is equipped with axis, and axis is inserted into the shaft coupling phase in charging axle rolling bearing 15 and in bearing Docking, shaft coupling dock this spiral charging axle 11 again.

The end of the close thrust rolling bearing 14 of spiral charging axle is equipped with check (non-return) valve 17.It is provided with Sample buffer pipe 7 Non-return valve 18.Non-return air valve 19 and pressure-regulating valve 20 are installed on exhaust tube 9.High pressure aspiration pump is high using small-sized single cylinder Aspiration pump is pressed, and the high pressure aspiration pump is fixed on sample transfer cylinder.Gas flow counterflow is prevented during the design of Non-return air valve 19, and is pressed Force regulating valve 20 can adjust the suction size of high pressure aspiration pump.

Referring to Fig. 1, the direction of arrow in figure is airflow direction, and high pressure pumping pump work starts to be evacuated, through rotation during pumping Wind separator, so can allow sample sipper tube draw sample for test particle, sample particle with suction airflow flowing, together It is fed in cyclone separator, cyclone separator carries out solid and gas separation to the air-flow of suction, and the air-flow after separation carries out up Taken away by high pressure aspiration pump, and sample particle then falls into following feed inlet, is entered by feed inlet in sample transfer cylinder, sample Spiral charging axle inside product transmission cylinder constantly sends out sample particle toward discharge port in the operation of rotational handle, due to The gradual thicker structure of spiral charging axle, for such sample particle toward during discharge port flowing in sample transfer cylinder, meeting is multiple The extruding of multi-angle is deposited in one piece, can ensure the state extrusion discharge port for allowing sample particle mutually to compress during conveying.It is such Operational method be advantageous in that from discharge port outflow sample particle when can at the uniform velocity flow out.

Above-described embodiment only expresses the several embodiments of the utility model, its description is more specific and detailed, but simultaneously Cannot be therefore understands that being the limitation to the utility model patent scope.It should be pointed out that the ordinary skill people for this area For member, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this reality With new protection domain.Therefore, the utility model patent and protection domain should be subject to the appended claims.
