The working principle of the embodiment is as follows: when the pipette is located at the initial position, the first air cylinder 311 retracts, the second blocking block 319 is tightly attached to the first squeezing arm and the second squeezing arm 54 from the lower side, the second squeezing column 313 is located between the first squeezing arm and the second squeezing arm 54, the rubber cap 322 is in an expansion state, the first bayonet 61 extends into the first bayonet, the first spring 316 is in a state of only supporting the first sliding block 317, the clamping component 321, the rubber cap 322 and the pipette 323, the first spring 316 is not compressed to a large extent, the pipette 323 retracts into the detection box 1 and the pipette 323 is in the highest state at the moment, the pipette 323 is prevented from being damaged in the transportation process, and at the moment, the first air cylinder 311 can push the push plate 300 to be located below the mounting plate 59 and can push the transfer funnel 331 to be located right below the pipette 323.
During sampling, the first cylinder 311 extends, firstly, the second cylinder 310 is kept in an extending state, at this time, the push plate 300 can prevent the mounting plate 59 from moving downwards, the push plate 300 has the function of generating bearing force on the mounting plate 59, and the situation that the elastic force of the first spring 316 is not enough to bear the mounting plate 59 and cannot move when the first bayonet pin 61 is separated from the first bayonet hole is avoided, so that a condition is provided for the subsequent separation of the first bayonet pin 61 from the first bayonet hole; then, the first stopper 315 and the second stopper 319 are controlled to move relative to the first pressing arm and the second pressing arm 54, the second pressing column 313, the truncated cone 314 and the first pressing column 312 sequentially pass through the first pressing arm and the second pressing arm 54, the truncated cone 314 plays a role of a span between the second pressing column 313 and the first pressing column 312, damage caused by excessive friction between the second pressing column 313 and the first pressing column 312 as well as between the first pressing arm and the second pressing arm 54 after the span is too large is avoided, as the diameter of the first pressing column 312 is larger than that of the second pressing column 313, as the first pressing column 312 is changed between the first pressing arm and the second pressing arm 54, the first clamping arm 51 and the second clamping arm approach each other, the rubber cap 322 is clamped, gas in the rubber cap 322 is removed, and at the same time, as a relative displacement between the first pressing column 312 and the first bayonet 61 is added, the mounting plate 59 is strongly supported by the push plate 300, the third spring 63 is forced to be elastically deformed, the first bayonet 61 is separated from the first bayonet hole, and finally the first blocking block 315 is in contact with the top end of the central column 57, so that the sampler has a downward moving trend under the pressure action of the first blocking block 315 on the first squeezing arm and the second squeezing arm 54, the relative displacement of the first bayonet 61 and the first squeezing column 312 cannot be changed any more at this time, the first spring 316 is in a compressed state at this time, the mounting plate 59 has an upward moving trend, but the relative displacement of the first bayonet 61 and the first squeezing column 312 cannot be changed any more due to the blocking action of the first blocking block 315, and the first cylinder 311 stops operating at this time, and the state is maintained; then, the second cylinder 310 retracts, so that the push plate 300 deviates from the mounting plate 59, and the transfer funnel 331 deviates from the suction pipe 323, so that the push plate 300 and the transfer funnel 331 are prevented from obstructing the movement of the whole collector; then, the first cylinder 311 continues to extend, slowly starts to press down the whole clamping assembly 321, the rubber cap 322 and the suction pipe 323, so that the suction pipe 323 moves downwards, at this time, since the first squeezing column 312 is always located between the first squeezing arm and the second squeezing arm 54, the first clamping arm 51 and the second clamping arm can always clamp the rubber cap 322, finally, the suction pipe 323 is pressed into the object to be tested, during the downward movement of the suction pipe 323, the movable rod 74 and the guide cylinder 75 are relatively displaced, the second latch 71 is aligned with the second latch hole when the suction tube 323 is inserted into the object to be tested, the second click 71 can be kept inserted into the second click hole by the elastic force of the fourth spring 73, at this time, although the first spring 316 is compressed to the minimum length, however, the elastic force of the first spring 316 is still insufficient to make the movable rod 74 and the guide cylinder 75 relatively displace under the limit action of the second detent 71, and the elastic force of the fourth spring 73 is sufficient; then, the first cylinder 311 retracts, and at the beginning, the second blocking block 319 does not contact with the first pressing arm and the second pressing arm 54, so that the sampler has no enough power, the first pressing column 312, the truncated cone 314, and the second pressing column 313 and the first pressing arm and the second pressing arm 54 are relatively displaced due to the limiting action of the second pin 71, finally, the second pressing column 313 is arranged between the first pressing arm and the second pressing arm 54, the second blocking block 319 is in contact with the first pressing arm and the second pressing arm 54, the first pin 61 also extends into the first clamping hole, and the first pressing column 312 and the first pin 61 are relatively displaced due to the insufficient elastic force of the first spring 316, so that preparation is provided for keeping the second pressing column 313 between the first pressing arm and the second pressing arm 54 in the subsequent lifting process, and at the same time, the first clamping arm 51 and the second clamping arm are kept under the elastic force of the torsion spring 58 to release the rubber cap 322, because the volume of the rubber cap 322 is suddenly increased, negative pressure is generated in the rubber cap 322 to suck the object to be measured, and the first air cylinder stops running within 3115 seconds to suck enough object to be measured in the rubber cap 322; then, the first cylinder 311 is continuously retracted, at this time, the first cylinder 311 enables the collector to have powerful ascending power through the second blocking block 319, instead of the power provided by the first spring 316, at this time, the moving rod 74 is forced to relatively displace with the guide cylinder 75, the moving rod 74 extrudes the second bayonet lock 71 out of the second bayonet lock, the second bayonet lock 71 is separated from the second bayonet lock, the moving rod 74 ascends, in this process, the second extrusion column 313 is kept between the first extrusion arm and the second extrusion arm 54 under the action of the first bayonet lock 61 and the first bayonet lock, so as to keep the first clamping arm 51 and the second clamping arm in a state of releasing the rubber cap 322 under the action of the torsion spring 58, and prevent the object to be measured in the rubber cap 322 from being extruded when the object to be measured does not need to be extruded yet, and finally ascends to the initial position; then, the second cylinder 310 is started to push the transfer funnel 331 to be right below the suction pipe 323, and meanwhile, the push plate 300 is positioned below the mounting plate 59; then, starting the first cylinder 311 to extend, so that the first extrusion column 312 moves downward relative to the first bayonet 61, the first extrusion column 312 extrudes the first extrusion arm and the second extrusion arm 54 to separate from each other, the first clamping arm 51 and the second clamping arm approach each other, the first clamping arm 51 and the second clamping arm extrude the rubber cap 322, so that the product to be measured in the rubber cap 322 drops into the transfer funnel 331, the product to be measured in the transfer funnel 331 enters the reaction chamber 2 through the rubber tube (in the process, the first valve is in a closed state), the weight sensor 90 detects the total weight of the reaction chamber 2 and the product to be measured, and finally when a set value is reached, the second valve is closed, the weight sensor 90 ensures that the product to be measured in the reaction chamber 2 is the same during each detection, and avoids the change of the quantity of the product to be measured from bringing about the change of the measurement result; then, starting the detection mechanism 4, detecting the content of the antibiotics in the to-be-detected object through reaction by a sensor in the detection mechanism 4, transmitting the content to the microcontroller, and transmitting the detection result to the master controller by the microcontroller to obtain the detection result; and finally, the master controller controls the first valve to be opened and the second valve to be opened, so that the to-be-detected object is completely removed from the detection box 1 at this time, and the influence on the next detection is avoided.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
