Step 54 in the cylinder of the axial location of piece-like tube 3 is combined with demifacet, for being combined to main piece-like tube, demifacet when piece-like tube is installed in axle
Positioned on to direction.
Specifically, the scalable sampling device that the present embodiment is provided, when only main piece-like tube participates in sample, without tight
Gu the participation of component, it is only necessary to scalable sampling flexible pipe 4 is put into main piece-like tube, treats the flexible pipe on scalable sampling flexible pipe 4
After pilot sleeve 41 is moved at sampling opening, main piece-like tube is inserted grain heap, at this moment connected the other end of scalable sampling flexible pipe 4
It is connected on the suction nozzle of electrical suction type sampling sharp-pointed tube, starts the operation that electrical suction type sampling sharp-pointed tube just completes sample；
When main piece-like tube is taken out in dismounting, electrical suction type sampling sharp-pointed tube is first shut off, scalable sampling flexible pipe 4 is pulled up and is connected to
One end on electrical suction type sampling sharp-pointed tube suction nozzle, then main piece-like tube is extracted out of grain heap using external auxiliary device；
When main piece-like tube and demifacet combination piece-like tube are involved in sample, first by the main fit key on the surface of main piece-like tube
12 coordinate with the L-shaped buckling groove 53 in connecting cylinder 5, and during cooperation, main fit key 12 is first directed at the L-shaped card in certain one end of connecting cylinder 5
The axial direction part of access slot 53, and axially section moves downward, and moves to the bottommost of L-shaped buckling groove 53 always, now rotates master
Piece-like tube or chain connect cylinder, circumferential sections of the main fit key 12 along L-shaped buckling groove 53 are made to rotate, untill it can not move,
Now the main bayonet 11 on main piece-like tube is aligned and is on coaxial position completely with the cylinder hole clipping 51 on connecting cylinder 5 just；At this moment
Scalable sampling flexible pipe 4 is put into main piece-like tube by connecting cylinder 5, treats the flexible pipe pilot sleeve on scalable sampling flexible pipe 4
After 41 move at sampling opening, main piece-like tube is inserted grain heap, is at this moment connected to the other end of scalable sampling flexible pipe 4 electronic
On the suction nozzle of suction sampling sharp-pointed tube, start electrical suction type sampling sharp-pointed tube, treat that main piece-like tube is advanced into grain heap under starting, and main piece-like tube
After part body enters grain heap, next just installation connects demifacet combination piece-like tube, will first form the two of demifacet combination piece-like tube
Individual semicircular pipe is clipped in the middle scalable sampling flexible pipe 4, and concavo-convex guide groove alignment on semicircular pipe is installed, thus formed
A piece complete demifacet combination piece-like tube, the scalable sampling around of flexible pipe 4 combine the inside of piece-like tube in demifacet, then make demifacet
Combination piece-like tube along it is scalable sampling flexible pipe 4 move, relief demifacet combination piece-like tube end face on semicircular pipe match somebody with somebody
The axial direction part of L-shaped buckling groove 53 that key 31 is aligned in the other end of connecting cylinder 5 is closed, and axially section moves downward, and moves to L always
The bottommost of the axial direction part of shape buckling groove 53；Next demifacet combination piece-like tube is rotated, makes semicircular pipe fit key 31 along L-shaped card
The circumferential sections of access slot 53 rotate, and untill it can not rotate, the semicircular pipe hole clipping 32 on now demifacet combination piece-like tube is proper
The good cylinder hole clipping 51 with connecting cylinder 5 is aligned completely to be on coaxial position, then by the semi-ring on flexible semi-ring buckle 2
Button 22 coordinates with main bayonet 11, semicircular pipe hole clipping 32, cylinder hole clipping 51, and semi-ring buckle frame 21 is fixed on buckle fixing groove
In 52, main piece-like tube, demifacet combination piece-like tube are just completed to the company between two pipes in the presence of connecting cylinder 5, semi-ring buckle 2
Connect.When needing to connect more demifacet combination piece-like tubes, the installation steps that need to only repeat above-mentioned demifacet combination piece-like tube can be real
Now deeper sample；
When main piece-like tube being combined into piece-like tube with demifacet taking apart, first the semi-ring button 22 on semi-ring buckle 2 from cooperation
Taken out in main bayonet 11 well, semicircular pipe hole clipping 32, cylinder hole clipping 51, semi-ring buckle 2 is fixed from the buckle on connecting cylinder 5
Groove 52 removes, and demifacet is then combined piece-like tube rotates towards the circumferential sections of L-shaped buckling groove 53 direction opposite with installation rotation, when
When can not rotate, the axial direction part towards the outside of connecting cylinder 5 along L-shaped buckling groove 53 pulls demifacet combination piece-like tube, until demifacet
Combination piece-like tube is completely pulled out unclamping after coming out of connecting cylinder 5, and demifacet combination piece-like tube will separate into two automatically, recycle
Extract servicing unit and main piece-like tube is extracted to dismounting and the withdrawal process for completing piece-like tube from grain heap in outside.
The scalable sampling device, can effectively solve existing piece-like tube connection total time-consuming is long, piece-like tube junction is easy to wear,
The problems such as piece-like tube can not rotate in grain heap when the gas leakage of piece-like tube junction and sample, improve piece-like tube connection speed and
Service life, make if necessary to make counterclockwise in grain heap during piece-like tube sample and can rotate clockwise, and occur without connection
The phenomenon that place loosens and piece-like tube comes off, further increase the depth selection of piece-like tube, save the time of sample, improve sample
Efficiency.
