It is adjusted, realizes normal sample and pump milk.
After sleeve 2 squeezes second piston cylinder 25, and electric pushrod is driven to complete the above movement, block plate 12 is moved to and Z at this time
The right side of shape pipe upper end transverse tube is in contact, and cannot move right again as negative pressure increases hollow rotating shaft 3 at this time, but in negative pressure
Effect lower sleeve 2 still has the tendency that moving right, and the first pressure spring 13 squeezes at this time, and sleeve 2 moves right, so that internal spline 10
There is disengaging trend with external splines 11, when negative pressure persistently increases, interior external splines 11 is detached from, and hollow rotating shaft 3 is no longer by interior flower at this time
Key 10 fetters, and after hollow rotating shaft 3, which is detached from, to be fettered, blade is started turning by milk thrust, and can be dredged milk, with this
Hollow rotation starts turning simultaneously, and the reciprocal feed screw nut 5 of the rotate driving of hollow rotating shaft 3 rotates, the rotation of reciprocal feed screw nut 5
Reciprocal lead screw 6 is driven to move left and right, reciprocal lead screw 6, which moves left and right, can make the piston reciprocating of first piston cylinder 7 mobile, reciprocal lead screw
Nut 5 can also give the trend of reciprocal lead screw 6 one rotations driving when the movement of reciprocal lead screw 6, at this time can be by living through first
It is rectangle to solve the problems, such as reciprocal lead screw 6 has rotation trend, in first piston cylinder 7 piston or so that plug cylinder 7, which is arranged to section,
It moves back and forth, it can be achieved that the milk in Z-type pipe 1 is sucked first piston cylinder 7 by inlet, and first lives by liquid outlet
Milk in plug is injected into corresponding sampling bottle 15 by syringe needle 8 and needle guard 9.
When after the collecting of all milk for completing a raiser, breast pump is closed, the negative pressure in zigzag thbe disappears, the
Under the reset response of one pressure spring 13, realize that internal spline 10 and external splines 11 engages fixation of the realization to hollow rotating shaft 3 again, second
The reset of pressure spring 26 realizes that second piston cylinder 25 resets, and second piston cylinder 25 sucks back the gas in air pressure push rod 27 again, gas
Pressure push rod 27 bounces back and realizes the reset of transverse slat 17, and transverse slat 17 resets the reset for realizing friction plate 19 first, and friction plate 19 resets
Realize that friction pulley 20 drives reel 31 to reset, rope 32 loosens at this time, and V-structure is realized under the reset response of tension spring 28
It resetting, needle guard 9, which moves up, at this time realizes that needle guard 9 is detached from sampling bottle 15, since sampling bottle 15 is fixed by rubber bottle cover 35,
Needle guard 9, which leaves sampling bottle 15, will not realize the movement of sampling bottle 15, with the lasts for reset of transverse slat 17, multiple ratchets 18 again with
Ratchet 16 contacts, but pawl 18 bounces back after contacting ratchet 16 at this time, so that the reset of transverse slat 17 will not drive turntable 14 to invert,
The milk source capsule of raiser is separated from the present apparatus after the completion, the milk carrying shield for changing next raiser can be realized to next family
Sampling and entrucking.
Present apparatus comparison traditional equipment has following benefit:
1, the present apparatus is invented according to China's milk cattle cultivating characteristic, after the milk source capsule of a raiser is connect with the present apparatus, milk
Breast pump on tank car first carries out vacuum suction, so that sleeve 2 moves right, realizes that second piston cylinder 25 is extruded and by power
It is delivered to air pressure push rod 27, so that transverse slat 17 is moved to the left, this process first makes turntable 14 rotate an angle, realizes sampling bottle 15
Conversion, then the rubbed 20 driving reels 31 of wheel of rubbed plate 19, which are realized the tightening of ropes 32 and then driven, needle guard 9 and adopts
The perforation of sample bottle 15, before sampling using milk tank vehicle per se with negative pressure equipment sampling bottle 15 is positioned and is placed automatically,
It does not need to increase driving device to sampling apparatus, while artificial place not being recycled to reduce operating process yet, reduce manually more
The temperature that can effectively reduce in sampling apparatus is changed after sampling bottle 15, conducive to the preservation of sample.
2, after turntable 14 rotates and completes and realize that sampling bottle 15 and syringe needle 8 penetrate through, with the lasting pressurization of breast pump
Realize that hollow circular-tube moves to extreme right position, internal spline 10 and external splines 11 are detached from, and realize blade rotate driving toward multifilament
The rotation of thick stick nut 5, reciprocal feed screw nut 5 drive reciprocal lead screw 6 to move left and right, and realize that first piston cylinder 7 will be in zigzag thbe
Milk is delivered in sampling bottle 15 through syringe needle 8, and first piston cylinder 7 selects capacity small, therefore may be implemented in entire sampling process
Milk is uniformly sampled so that sampling process is more rationally abundant, while the present apparatus carries out flexibility according to each household milk supply amount and adopts
Sample, how many milk is sampled by same ratio, after the completion of sampling, regardless of in sampling bottle milk amount how much, may be implemented to sample
Bottle transformation, relatively external sample mode at regular time and quantity are more suitable China's national situation.
3, the present apparatus certainly will need to close breast pump when replacing the milk carrying shield at different breeding family, stop work in breast pump
After work, second piston cylinder 25 resets so that transverse slat 17 resets, and it is de- with syringe needle 8 to have adopted excellent sampling bottle 15 for realization during this
From sleeve 2 is reset to original state again, while internal spline 10 and external splines 11 engage again, carries out for next family raiser
Sampling provides good sampling environment and state, therefore the replacement of sampling bottle 15 depends on the switch of breast pump, reduces operation
Sample devices cost is decreased while process.
Present inventive concept is novel, clever structure is practical, and the existing milk sampling apparatus of effective solution does not adapt to
China using family as in unit breeding process sampling keep on file when one family one of sampling bottle change cumbersome, the low problem of the degree of automation.
