Embodiment:

One, sampling prepares:

Sterile multilayer pin type solid air-sampler sterilizing sleeve is installed before operation in the sampling main body 12 of solid air-sampler 1, close all valves；Rotational handle 5, runner 6 rotate, and runner 6 drives transmission shaft 7 to rotate, and gear b13 pushes triangle hopper to push away Bar 16, and then push triangle hopper 28 to 7 end motion of teletransmission moving axis, triangle hopper 28 pushes sliding door 22 to move upwards, and slides Door 22 upper end oblique compression outer walls, lateral compression idler wheel 33, idler wheel 33 push push rod 21, and push rod 21 pushes sliding block b36 to squeeze bullet Spring b20, sliding door 22 enter slideway 35 and push sliding block a34, squeeze spring a19 and move upwards along slideway 35,22 lower edge of sliding door Along 28 bevel edge upward sliding of triangle hopper, 22 part of sliding door is opened, rotating wheel 6, makes to correct before triangle hopper 28 to skid off 12 outer wall of main body is sampled, while touching sterile multilayer pin type solid air-sampler sterilizing 1 inner wall of sleeve, at this time at triangle hopper 28 In partially open state；11 steam-out (SO) of steam inlet, opens valve a10, and steam enters sampling 12 outer wall of main body and sleeve 1 In the gap formed between inner wall, then is entered by the gap that sliding door 22 is opened and sampled inside main body 12, Open valve b31, Cold air, control valve a10 and valve b31 is discharged by condensation-water drain 30, controls sterilization pressure and temperature to sampling main body 12 inner cavities and outer wall sterilize.Sterilizing terminates to close valve a10 and valve b31, disconnects steam connection, rotates backward handle 5 Rotating wheel 6 drives transmission shaft 7 to rotate backward, and gear b13 pulls triangle hopper 28 to nearly 7 end motion of transmission shaft, sliding door 22 In the case where spring a19 and sliding block a34 is pushed, moves downward along 28 bevel edge of triangle hopper and fallen under the guidance of the magnet of strength 18 In the card slot 32 being arranged below sliding door 22,22 upper end of sliding door under the promotion of spring b20, sliding block b36 and door push rod 21 with The chimeric recovery of main body 12 is sampled, sampling main body 12 and inner cavity form enclosure space, spare.

Two, sampling step:

The sleeve 1 of the sterile multilayer pin type solid air-sampler of removal before sampling, sampling main body 12 is inserted into according to set depth Solid fermentation matrix is other wait adopt in solid sample, rotational handle 5, and the rotation of runner 6 drives transmission shaft 7 to rotate, and gear b13 is pushed away Dynamic triangle hopper push rod 16, and then push triangle hopper 28 to 7 end motion of teletransmission moving axis, triangle hopper 28 pushes sliding door 22 It moves upwards, the 22 lateral squeezing roller 33 of upper end oblique compression outer wall of sliding door, idler wheel 33 pushes push rod 21, and push rod 21, which pushes, to be slided Block b36 squeezes spring b20, and sliding door 22 enters slideway 35, and sliding block a34 is pushed to squeeze spring a19 and transport upwards along slideway 35 Dynamic, 22 lower edge of sliding door is along 28 bevel edge upward sliding of triangle hopper, and triangle hopper 28 is along triangle hopper sliding way 26 and three corner materials Struggle against glide path 27, stretches out sampling main body 12 and is inserted into solid fermentation matrix, when edge is in sampling main body 12 on triangle hopper 28 When on inner wall extended line, the stopping of triangle hopper 28 is moved out, and matrix fills 28 middle cavity of triangle hopper.In rotational handle 5, The rotation of runner 6 drives the rotation of transmission shaft 7 simultaneously, and gear a9 pushes material cutter push rod 14 and material cutter 38, with triangle hopper 28 bevel edge parallel directions oliquely downward move, when on triangle hopper 28 along arrival sampling 12 inner wall extended line of main body fixed point, just Good 38 edge of a knife of solid material cutter passes through the gap that material cutter top guide bar 24 and material cutter lower guide rod 25 are formed, and reaches solid 12 inner wall extended line of main body fixed point is sampled, handle 5,28 stop motion of triangle hopper are continued to rotate, and material cutter 38 is along three The continuation of 28 bevel edge of corner material bucket oliquely downward moves to 28 front end bottom edge of triangle hopper, and solid material cutter 38 cuts solid fermentation Matrix makes to enter fermentation substrate (solid material) and external fermentation substrate (solid material) inside triangle hopper 28 and disconnects.

Handle 5 is rotated backward, the rotation of runner 6 drives transmission shaft 7 to rotate backward, and gear a9 pulls material cutter 38 and material Cutter push rod 14 reversely playbacks along material cutter slideway 17；When 38 edge of a knife of material cutter is withdrawn into fixed point, gear b13 is pulled Triangle hopper 28 is to nearly 7 end motion of transmission shaft, and sliding door 22 is in the case where spring a19 and sliding block a34 is pushed along 28 bevel edge of triangle hopper It moves downward, and is fallen into 22 lower end card slot 32 of sliding door under the guidance of strong magnets 18,22 upper end of sliding door is in spring Chimeric with sampling main body 12 under the promotion of b20, sliding block b36 and push rod 21 to restore, sampling main body 12 and inner cavity form enclosure space, Sampling terminates.

Sample takes out: rotating in the forward direction handle 5 in outside and sends out half triangle hopper 28, solid material takes from triangle hopper 28 Out.

The material cutter push rod 14, triangle hopper slideway 15, triangle hopper push rod 16 and material cutter slideway 17 are tooth Wheel-like structure, the cutter push rod 14 drive material cutter 38 to move back and forth in material cutter slideway 17, the gear a9, gear B13 and the material cutter push rod 14, triangle hopper push rod 16 intermesh, and gear a9, gear b13 diameter proportion is arranged, when When sampling, controls edge and 38 edge of a knife of material cutter on triangle hopper 28 and reached on sampling 12 inner wall extended line of main body simultaneously, simultaneously The limitation stopping of triangle hopper 28 of 16 tail end of triangle hopper push rod moves out；When rotating backward handle 5,38 He of material cutter Triangle hopper 28 playbacks, and control material cutter 38 is withdrawn on sampling 12 inner wall extended line of main body, continues to rotate handle 5, triangle Hopper 28 and material cutter 38 are classified as simultaneously, and feeding terminates.

Above description is only a specific implementation of the present invention, but the protection scope of utility model is not limited to This, anyone skilled in the art within the technical scope disclosed by the utility model, the variation that can readily occur in or is replaced It changes, should all cover within the protection scope of utility model.
