Description

Technical Field

[0001] The invention relates to the technical field of sampling devices, in particular to a milk product detection sampling device. Background Art

[0002] With the development of animal husbandry technology, dairy farms have now used semi-automatic and fully automated mechanical devices to complete milking and feeding. One of the more common ones is the sampler, which is a tool for sampling milk for testing.

[0003] The existing sampler assembled on the milk delivery pipeline has a structure such as the sampler proposed in the patent with publication number CN206756501U, which "connects the tee in series in the pipeline of automatic vacuum negative pressure milking, wherein the milk inlet is connected to the milk, and the milk outlet is discharged. When milking is normal and sampling is not required, the sealing cover is covered on the outlet, so that the entire tee remains sealed, ensuring that the milk does not contact with the external air, and thus no bacteria will grow. When it is necessary to sample and test the milk, the sealing cover is removed from the tee, and the bottle mouth is installed on the tee so that the outlet is connected to the bottle mouth, and the sealing cover is sealed at the same time. It is arranged at the upper part of the bottle mouth, and the bottle body is installed at the lower part of the bottle mouth. The bottle body and the lower part of the bottle mouth are screwed to ensure the airtightness of the entire sampler. At the same time, the cover is rotated. Since the cover is also provided with a switch component for controlling the conduction of the liquid outlet, the switch component is a cylindrical cylinder, which fits with the inner wall of the bottle mouth. The surface of the cylindrical cylinder is provided with a notch for making the liquid outlet conductive. When the cylindrical cylinder fits with the inner wall of the bottle mouth, the liquid outlet remains in a sealed state. When it is rotated until the notch faces the liquid outlet, a gap will be formed between the liquid outlet and the cylindrical cylinder to achieve conduction, and the milk in the vacuum negative pressure milking pipeline will enter the bottle body.

[0004] The above sampler has the following defects: after the sampling is completed, the liquid inlet for sampling needs to be closed manually, which is inconvenient to operate. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a milk product detection sampling device, which solves the problem that the sampling liquid inlet needs to be manually closed after the sampling is completed, which is inconvenient to operate.

[0009] Furthermore, an auxiliary spring is fixedly disposed on one end of the second spring seat away from the spring, and a spring seat three for mounting the auxiliary spring is fixedly disposed on the inner wall of the outer cylinder.

[0010] Furthermore, a support ring is provided on the outer cylinder at a position opposite to the slope block, and a hollow portion for accommodating the support ring is opened on the slope block.

[0011] Furthermore, a threaded cylinder is provided at one end of the cover body close to the outer cylinder, and the outer cylinder and the threaded cylinder are threadedly connected so that the outer cylinder can be detached from the second end cover; a long hole is axially opened on the force arm, and the pin shaft on the shaft seat can slide in the long hole; an integrated convex portion is provided on one side of the supporting ring, and a rotating ring is rotatably installed on the outer arc surface of the outer cylinder, and spokes are fixed between the rotating ring and the convex portion.

[0016] The present invention has the following beneficial effects:

[0017] (1) The dairy product detection sampling device can achieve the purpose of "plug and open" and "pull and close" through the mutual cooperation of the sealing piece on the three-way pipe and the force-applying part on the connector. That is, when one end of the three-way pipe is inserted into the insertion tube, the sealing piece can be automatically opened. When the storage bottle and the connector are pulled out from the three-way pipe, the sealing piece can be automatically closed without manual closing, which is easy to operate.

[0018] (2) The dairy product detection sampling device is provided with a force arm, a clamping block and a slope block. When the slope block is subjected to a force along the radial direction of the outer cylinder, the force arm can produce a certain angle change on the shaft seat, thereby driving the clamping block to clamp on the insert, thereby realizing a stable connection between the connector and the three-way pipe.

[0019] (3) The milk product detection sampling device sets the spring in the outer cylinder so that the entire spring is not located in the three-way pipe, so it will not contact the milk in the three-way pipe, reducing the difficulty of cleaning.

[0020] (4) The dairy product detection sampling device can achieve the purpose of "plug and turn on" and "pull and turn off" while having a simple structure by providing a second blocking member.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0042] According to the following Figure 1-Figure 17 The dairy product detection and sampling device provided in an embodiment of the present invention is described.

[0043] Embodiment 1

[0044] See also Figure 1-Figure 2 The embodiment of the present invention provides a milk product detection sampling device, the main body of which is composed of three parts, including a storage bottle 100, a connector 200 and a three-way pipe 400. The storage bottle 100 is used to store the milk sample for random inspection, and the connector 200 is used to connect the three-way pipe 400 and the storage bottle 100. In the non-sampling state, the three-way pipe 400 is locked on the milk delivery pipeline of the milking machine by the locking structure 300 alone. In the sampling state, the storage bottle 100 with the connector 200 is assembled on the three-way pipe 400.

[0045] The locking structure 300 mentioned here should include a clamp that is clamped on the three-way pipe 400 and a U-shaped lock connected to the clamp. The U-shaped lock can be directly locked on the milk delivery pipeline.

[0046] It should be noted here that the three-way pipe 400 includes a main body 410, and a liquid inlet pipe 420 and a liquid outlet pipe 430 are respectively arranged on both sides of the main body 410. In the non-sampling state, the milk discharged by the milking machine enters the main body 410 through the liquid inlet pipe 420 and is discharged through the liquid outlet pipe 430; in the sampling state, the milk in the main body 410 not only enters the liquid outlet pipe 430, but also enters the storage bottle 100 through the connector 200.

[0047] Combination Figure 4 As shown, the above-mentioned connector 200 includes a connecting tube body 210, a plug 240 arranged on one side of the connecting tube body 210, and an end cover 230 nested in the upper end of the connecting tube body 210. When the connecting tube body 210 needs to be cleaned, it is only necessary to remove the entire end cover 230 and remove the entire connecting tube body 210 from the storage bottle 100.

[0048] A plug cover 250 is hung on one side of the bottle mouth of the storage bottle 100, and the plug cover 250 can be used to seal the plug 240 separately, so that the storage bottle 100 carrying the connector 200 can be sent to the inspection room for inspection.

[0049] After the insertion tube cover 250 is opened, the adapter 200 can be assembled on the tee pipe 400 to facilitate communication with the tee pipe 400 .

[0050] A sealing gasket 220 is provided at the lower end of the connecting tube body 210. The sealing gasket 220 is used to seal the gap between the connecting tube body 210 and the bottle mouth of the storage bottle 100 when the connecting tube body 210 is assembled on the storage bottle 100, so as to avoid leakage during the sampling process.

[0051] The actual connection tube body 210 and the bottle mouth of the storage bottle 100 can be connected by a threaded connection or a plug-in connection. When the storage bottle 100 needs to be cleaned, the connection tube body 210 can be removed from the storage bottle 100. In actual use, the connection tube body 210 and the storage bottle 100 are inseparable, even in the inspection stage. When the milk needs to be poured out of the storage bottle 100, the milk is also poured out from the insertion tube 240. In summary, the connection tube body 210 and the storage bottle 100 are separated only in the cleaning stage; even the connection tube body 210 and the bottle mouth of the storage bottle 100 can also be integrally formed (such as Figure 3 As shown), the sealing gasket 220 is no longer needed. In this embodiment, the two are separated only to facilitate the cleaning of the storage bottle 100. Once the two are formed as one, the bottle mouth of the storage bottle 100 will be longer, making it inconvenient to clean the inside of the storage bottle 100.

[0052] A force-applying portion 260 is fixedly provided on the lower end surface of the end cover 230, and the main body 410 is inserted into the insert tube 240. The inner wall of the insert tube 240 should be equipped with a corresponding sealing ring (not shown in the figure). On the one hand, this sealing ring can avoid leakage from the insertion gap between the three-way pipe 400 and the insert tube 240, and on the other hand, it can make the three-way pipe 400 and the insert tube 240 more firmly connected, avoiding the three-way pipe 400 and the storage bottle 100 from falling off the three-way pipe 400.

[0053] Combination Figure 4-Figure 7 As shown, the dairy product detection sampling device provided in the embodiment of the present invention also includes a sealing piece, which is arranged at one end of the three-way pipe 400 close to the connector 200. The sealing piece can block or not block the end of the three-way pipe 400 close to the connector 200; when the three-way pipe 400 is inserted into one side of the connector 200, the force-applying part 260 can apply pressure to the sealing piece to open the sealing piece, and when the three-way pipe 400 is separated from the connector 200, the sealing piece loses the pressure of the force-applying part 260 and closes.

[0054] Therefore, the dairy product detection and sampling device provided in the embodiment of the present invention can achieve the purpose of "plug and open", that is, when one end of the three-way pipe 400 is inserted into the insertion tube 240, the blocking piece can be automatically opened, and when the storage bottle 100 and the connector 200 are pulled out from the three-way pipe 400, the blocking piece can be automatically closed without manual closing.

[0055] Continue to refer to Figure 4-Figure 7 As shown, one end of the three-way pipe 400 inserted into the insertion pipe 240 is provided with a discharge port 411 , and the milk in the three-way pipe 400 can enter the connecting pipe body 210 through the discharge port 411 .

[0056] The above-mentioned blocking member includes a first blocking member 500, which includes a conical blocking body 510. The conical blocking body 510 is located at the junction of the tee pipe 400 and the discharge port 411, so that when no sampling is performed (i.e., when the connector 200 has not been inserted into the main pipe body 410), the conical blocking body 510 can block the discharge port 411, so that the milk in the main pipe body 410 can only reach the liquid outlet pipe 430 from the liquid inlet pipe 420.

[0057] Preferably, the second end cap 520 is nested at the end of the tee pipe 400 away from the connecting pipe body 210 to block the end of the tee pipe 400 away from the connecting pipe body 210, thereby preventing milk from leaking from this end.

[0058] In addition, in order to ensure that the conical sealing body 510 has sufficient sealing force, an outer cylinder 590 is also arranged at the end of the end cover 520 away from the tee pipe 400, and a spring 540 is arranged inside the outer cylinder 590. A long rod 530 is fixed between the spring 540 and the conical sealing body 510, and the long rod 530 passes through the end cover 520 along the axial direction of the end cover 520, so that the spring 540 squeezes the conical sealing body 510 into the area where the tee pipe 400 and the discharge port 411 intersect through the long rod 530, thereby realizing that the conical sealing body 510 can completely seal the discharge port 411.

[0059] In this embodiment, since the entire spring 540 is not located in the three-way pipe 400, it will not contact the milk in the three-way pipe 400, thereby reducing the difficulty of cleaning.

[0060] In order to realize that the force-applying part 260 can apply pressure to the conical blocking body 510 to displace the conical blocking body 510, a force-bearing rod 511 is also provided. The force-bearing rod 511 is fixed on the side of the conical blocking body 510 close to the force-applying part 260. When the three-way pipe 400 is inserted into the insertion tube 240, the force-applying part 260 can squeeze the force-bearing rod 511 to make the force-bearing rod 511 separate from the junction area of ​​the three-way pipe 400 and the outlet 411, thereby forming Figure 4 In the state shown, the milk in the three-way pipe 400 can enter the connecting pipe body 210 through the discharge port 411 and then reach the storage bottle 100.

[0061] Preferably, a first spring seat 541 is fixedly provided at one end of the spring 540 close to the second end cover 520 , a second spring seat 542 is fixedly provided at the other end of the spring 540 , and the long rod 530 is fixed on the first spring seat 541 .

[0062] The above structure can well achieve the purpose of "plug and play", but it still has certain problems, that is, since the conical blocking body 510 is squeezed by the force-applying part 260, the spring 540 is compressed, resulting in insufficient stability of the entire three-way pipe 400 on the insertion tube 240, that is, the connector 200 and the storage bottle 100 are very likely to fall off the three-way pipe 400. In order to solve this problem, the following solution is given, as follows: Figure 4-Figure 7 As shown in the figure, the second end cover 520 includes a cover body 523, a second sealing plug 521 fixedly arranged at the central area of ​​the cover body 523 near the tee pipe 400 (the second sealing plug 521 can prevent milk leakage), and a support tube 522 fixedly arranged at the outer edge area of ​​the cover body 523 near the tee pipe 400. The outer arc surface of the support tube 522 is provided with at least two shaft seats 524 (four shaft seats 524 are provided in this embodiment), and a force arm 570 is rotatably installed on the shaft seat 524. The force arm 570 is supported by the outer arc surface of the support tube 522. A clamping block 571 is provided at one end near the insert tube 240, and a slope block 550 is fixedly provided at one end of the force arm 570 close to the outer cylinder 590, and the side of the slope block 550 close to the outer cylinder 590 is an inclined surface; when the slope block 550 is subjected to a force along the radial direction of the outer cylinder 590, the force arm 570 can produce a certain angle change on the shaft seat 524, thereby driving the clamping block 571 to clamp on the insert tube 240, thereby realizing a stable connection between the connector 200 and the tee pipe 400.

[0063] Preferably, a serrated structure is provided on the clamping surface of the clamping block 571 , and a serrated structure is also provided on the outer surface of the insert tube 240 , so the cooperation of the two can further prevent the connector 200 from falling off the tee pipe 400 .

[0064] Continue to refer to Figure 4-Figure 7 In order to achieve the purpose of subjecting the above-mentioned slope block 550 to the radial force along the outer cylinder 590, the side of the above-mentioned second spring seat 542 away from the spring 540 also has a certain movable distance, a slider 560 is fixedly provided in the outer periphery of the second spring seat 542 in the area opposite to the slope block 550, and a slide groove 595 is axially opened in the area opposite to the slider 560 on the outer cylinder 590, an auxiliary spring 580 is fixedly provided at the end of the second spring seat 542 away from the spring 540, and a spring seat three 581 for installing the auxiliary spring 580 is fixedly provided on the inner wall of the outer cylinder 590.

[0065] In this embodiment, when the conical plugging body 510 blocks the discharge port 411, the spring 540 and the auxiliary spring 580 are both in a natural state. When the conical plugging body 510 is pushed, the elastic coefficient of the auxiliary spring 580 is small, so the long rod 530 pushes the first spring seat 541, the spring 540 and the second spring seat 542 simultaneously, and the auxiliary spring 580 and the spring 540 are both compressed. In this process, the slider 560 on the second spring seat 542 gradually pushes the inclined surface, thereby The surface block 550 drives the power arm 570 to rotate along the shaft seat 524, forming a state in which the clamping block 571 clamps the cannula 240, and due to the compression of the spring 540, the second spring seat 542 on the right is subjected to a rightward elastic force, so that the slope block 550 is subjected to a radial outward thrust, thereby further improving the clamping degree of the clamping block 571; conversely, when the conical sealing body 510 loses thrust, the auxiliary spring 580 is responsible for pushing the first spring seat 541, the spring 540 and the second spring seat 542 back to their original positions.

[0066] like Figure 5-Figure 9 As shown, in order to maintain the stability of the force arm 570 and the slope block 550, a support ring 591 is provided on the outer cylinder 590 at a position opposite to the slope block 550, and a hollow portion 551 for accommodating the support ring 591 is opened on the slope block 550, so that the circumferential position of the slope block 550 outside the outer cylinder 590 is locked, ensuring the stability of the position of the force arm 570 and the slope block 550, so that the clamping block 571 can better clamp on the cannula 240.

[0067] Preferably, the axial width of the portion of the support ring 591 located outside the hollow portion 551 is greater than the width of the hollow portion 551 , thereby limiting the circumferential position of the ramp block 550 on the support ring 591 and further maintaining the stability of the ramp block 550 .

[0068] It should be noted that the radial length of the hollow portion 551 along the supporting ring 591 is greater than the ring thickness of the supporting ring 591 , so that the supporting ring 591 can generate relative displacement in the hollow portion 551 .

[0069] When the inside of the three-way pipe 400 needs to be cleaned, it is only necessary to pull the end cap 2 520 off the three-way pipe 400, so that the outer cylinder 590 (including the components inside the outer cylinder 590), the long rod 530, the conical plugging body 510 and the force-bearing rod 511 can all be removed from the three-way pipe 400 to form a Figure 7 The state shown is convenient for cleaning the long rod 530 , the conical blocking body 510 and the force-bearing rod 511 , and is also convenient for cleaning the three-way pipe 400 .

[0070] In addition, since the long rod 530 passes through the second end cover 520, after long-term use, the milk in the three-way pipe 400 will penetrate into the outer cylinder 590 along the outer surface of the long rod 530 in a small amount. Therefore, in order to facilitate the cleaning of the outer cylinder 590, a threaded cylinder 526 is provided at one end of the cover 523 close to the outer cylinder 590, and the outer cylinder 590 and the threaded cylinder 526 are threadedly connected so that the outer cylinder 590 can be separated from the second end cover 520, and a long hole 572 is opened in the axial direction of the force arm 570, and the pin shaft on the shaft seat 524 can slide in the long hole 572, so that the outer cylinder 590 and the second end cover 520 can form a Fig.10 Status shown.

[0071] It should be noted that an integral convex portion 592 is provided on one side of the support ring 591, and a rotating ring 594 is rotatably installed on the outer arc surface of the outer cylinder 590. Spokes 593 are fixed between the rotating ring 594 and the convex portion 592, so that the support ring 591 can be supported on the outer cylinder 590, and when the outer cylinder 590 is rotated to separate from the end cover 2 520, the rotating ring 594 does not rotate, so that the rotating ring 594, the slope block 550, and the force arm 570 remain relatively stationary with the end cover 2 520.

[0072] When in use (working), in a state where no sampling is performed, the three-way pipe 400 is locked on the milk delivery pipeline of the milking machine by the locking structure 300 alone.

[0073] In the sampling state, the storage bottle 100 with the connector 200 is assembled on the three-way pipe 400. When performing the specific assembly operation, the insertion tube 240 on the connector 200 with the storage bottle 100 is aligned with one end of the main body 410, and the main body 410 is gradually inserted into the insertion tube 240. During the gradual insertion process, the force-applying part 260 will push the force-bearing rod 511. At this time, the force-bearing rod 511 drives the conical blocking body 510 to the right to separate from the discharge port 411. The conical blocking body 510 pushes the first spring seat 541 to the right through the long rod 530. Since the elastic coefficient of the auxiliary spring 580 is small, the long rod 530 synchronously pushes the first spring seat 541, spring 540 and second spring seat 542, auxiliary spring 580 and spring 540 are all compressed. During this process, the slider 560 on the second spring seat 542 gradually pushes the inclined surface, so that the slope block 550 drives the power arm 570 to rotate along the shaft seat 524, forming a state in which the clamping block 571 clamps the cannula 240, and due to the compression of the spring 540, the second spring seat 542 on the right side is subjected to the rightward elastic force of the spring 540, so that the slope block 550 is subjected to a radial outward thrust, thereby further improving the clamping degree of the clamping block 571; the above process completes the conduction of the sampling pipeline and the stable connection between the three-way pipe 400 and the connector 200.

[0074] After sampling is completed, the storage bottle 100 and the connector 200 are manually unplugged from the three-way pipe 400. At this time, the conical sealing body 510 loses its thrust, and the auxiliary spring 580 is responsible for pushing the first spring seat 541, the spring 540 and the second spring seat 542 back to their original positions. The spring 540 is responsible for pushing the conical sealing body 510 to the left through the long rod 530 to re-seal the discharge port 411.

[0075] After removing the storage bottle 100 and the adapter 200, cover the cannula 240 with the cannula cover 250 and send it for inspection.

[0076] Embodiment 2

[0077] Combination Figure 11-Figure 17 As shown, the difference between this embodiment and the first embodiment is that the blocking member includes a second blocking member 600 , and the second blocking member 600 includes elastic spokes 620 , a vertical portion 621 and an elastic diaphragm 610 .

[0078] The elastic spokes 620 here are arranged radially in a cone shape, and the ends of the multiple elastic spokes 620 close to the center of the radiation circle are not connected, the vertical portion 621 is arranged at the end of the elastic spoke 620 away from the center of the radiation circle, the elastic diaphragm 610 is fixed between the elastic spokes 620 and the vertical portion 621, the outer edge of the elastic diaphragm 610 and the vertical portion 621 are sealed in the inner wall of the tee pipe 400, and the force-applying portion 260 here is fixed with a push cylinder 270 at one end close to the tee pipe 400, and the push cylinder 270 is provided with a conical head 271 at one end close to the tee pipe 400, and the side wall of the push cylinder 270 is radially opened with a liquid channel hole 272.

[0079] In this embodiment, when sampling is not performed, the connector 200 has not yet been plugged into the tee pipe 400, and the elastic spokes 620 are in a natural state. Fig.15 As shown in the closed state, the milk is only discharged from the liquid outlet pipe 430; in the sampling state, the three-way pipe 400 is plugged into the adapter 200, and the conical head 271 first pushes each elastic spoke 620 to change the inclination of the elastic spoke 620, thereby forming Fig.12 , Fig.13 , Fig.14 and Fig.16 state, at this time, the elastic diaphragm 610 is in a state of being stretched under force, and the milk is fed from the liquid channel hole 272 that passes through the second blocking member 600, and is discharged from the liquid channel hole 272 that does not pass through the second blocking member 600 into the connector 200.

[0080] In addition, it is worth mentioning that since the second blocking member 600 is located at one end of the three-way pipe 400, it is also relatively convenient to clean.

[0081] Furthermore, in this embodiment, an end seal should also be provided at the end of the main pipe 410 away from the connector 200 .
