Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of agricultural product detection, and in particular relates to a novel veterinary drug residue detection device. Background Art
[0002] Veterinary drug residues refer to the residues of the original drug or its metabolites, including veterinary drug-related impurities, that accumulate or remain in the bodies of livestock and poultry or products (such as eggs, milk products, meat products, etc.) after drug use. As people shift from demand-oriented to quality-oriented approaches to animal-derived foods, more and more attention has been paid to the issue of pesticide and veterinary drug residues, and a dedicated veterinary drug residue detection device is required to detect veterinary drug residues in meat products.
[0003] In the prior art, the type and content of drugs in meat products can be detected by veterinary drug residue detectors. However, during the detection process, workers are required to perform manual sampling, prepare detection solutions, etc., which results in low efficiency of this detection method. In addition, since agricultural and sideline products are produced and sold in large quantities, the existing detection methods cannot meet market demand. In addition, since the detection process is entirely manual, there will be a problem of insufficient detection precision, which affects the detection data. At the same time, since manual operations are exposed to the air, some impurities may be mixed in during the operation, which will also affect the test results to a certain extent.
[0004] In addition, due to the different compositions of the skin, muscles, and fat in the animal groups, the drug residues in different parts are also different. Therefore, in order to reduce interference factors during testing, the skin and flesh of the animal tissues need to be separated to eliminate the influence of skin and fat on the test. The muscle parts should be tested uniformly to improve the accuracy of the test. However, the above operation requires manual separation by the staff, which increases the extra workload and reduces the detection efficiency. Summary of the invention
[0005] In order to solve the problems in the prior art, the present invention addresses the technical problem that fat will adversely affect the accuracy of veterinary drug detection. It utilizes a contact-type detection method to automatically identify lean meat and fat meat, and linkage control sampling, thereby achieving the technical effect of automatic screening and sampling, avoiding adverse factors affecting detection, and improving detection accuracy.
[0006] The technical solution adopted by the present invention is as follows: The present invention is a new type of veterinary drug residue detection device, including a detection box, a sampling mechanism, a multi-dimensional shaking mechanism, a dripping mechanism, an injection mechanism and a veterinary drug detector. A linear guide rail is provided on the top of the detection box, and the sampling mechanism, the multi-dimensional shaking mechanism, the dripping mechanism and the injection mechanism are all connected with a guide rail slide that is slidably connected to the linear guide rail, so as to control the movement of the sampling mechanism, the multi-dimensional shaking mechanism, the dripping mechanism and the injection mechanism. A sampling table is provided in the detection box for placing animal tissue to be tested, a test tube placement table is provided in the detection box for placing test tubes, and a water bath pot for detection is provided in the detection box.
[0007] Furthermore, the sampling mechanism includes a sampling hydraulic rod, a sampling main rod, a sampling clamp, a guide drive sleeve and a lifting sampling tube. The sampling main rod is arranged on the sampling hydraulic rod, and the sampling clamp is arranged at the bottom of the sampling main rod. The animal tissue to be tested is grabbed by the sampling clamp. In the prior art, when manually sampling animal tissue, the animal tissue is cut by a knife, and then weighed and tested. During the process, not only is the cutting inconvenient, but the manual cutting is not accurate in weight control. Therefore, multiple cuttings are required to balance the weight to a suitable mass. Therefore, in the present application, a lifting sampling tube is provided. The lifting sampling tube is sleeved on the outside of the sampling main rod, and the lifting sampling tube can be lifted and slid on the outside of the sampling main rod. An annular cutting knife is provided at the bottom of the lifting sampling tube. In order to control the lifting movement of the lifting sampling tube, a lifting control section is provided on the inner wall of the lifting sampling tube. The lifting control section is composed of a plurality of groups of continuously arranged annular grooves. An internal cavity is provided in the sampling main rod. A connecting opening is provided on the internal cavity. A lifting driving gear is provided in the internal cavity. The lifting driving gear extends out of the connecting opening and meshes with the lifting control section. A lifting motor is provided in the internal cavity. The lifting motor is connected to the lifting driving gear. The lifting driving gear rotates and drives the lifting sampling tube to rise and fall through the lifting control section, thereby cutting the tissue when descending and lifting it after cutting to avoid obstruction to the sampling clamp.
[0008] In order to achieve the effect of cutting animal tissue and control the lifting sampling tube to make rotatable movement, a guide drive sleeve is arranged to be rotatably arranged on the outside of the sampling main rod, and the inner wall of the guide drive sleeve is provided with a rotation drive section, and the rotation drive section is a vertical rack arranged along the circumference of the inner wall of the guide drive sleeve. The lifting sampling tube is provided with a rotation connection section, and the rotation connection section is a vertical rack arranged along the circumference of the outer wall of the lifting sampling tube. The guide drive sleeve is sleeved on the outside of the rotation drive section, and the two are meshed with each other, and the lifting sampling tube can slide up and down relative to the guide drive sleeve. , and then when the guide drive sleeve rotates, the rotary connecting section is driven to rotate through its rotary drive section, so that the annular cutting knife generates a rotary cutting force, thereby improving the cutting effect, and when the lifting sampling tube performs lifting and sliding motion, since the guide drive sleeve and the lifting sampling tube are meshed through the vertical rack, the two can also slide relative to each other when rotating; similarly, when the lifting sampling tube performs rotational motion, the lifting control section and the lifting driving gear are connected in a rotational sliding manner, thereby realizing that the lifting sampling tube can perform both rotational motion and lifting motion, thereby achieving the effect of quickly cutting animal tissue.
[0009] Furthermore, in order to drive the rotation of the guide drive sleeve, a sampling gear ring is provided on the outer side of the guide drive sleeve, a driving support plate is provided on the sampling main rod, a rotating driving gear meshing with the sampling gear ring is provided on the driving support plate, and a rotating driving motor connected to the rotating driving gear is provided on the driving support plate.
[0010] Furthermore, in order to automatically distinguish lean meat from fat meat, a meat quality detection mechanism is arranged in the internal cavity, and the meat quality detection mechanism comprises a detection hydraulic rod, a contact rod, a built-in sleeve, a built-in trigger rod, a detection shell and a limiter, the detection shell is arranged on the detection hydraulic rod, a sleeve slide groove is arranged in the detection shell, the built-in sleeve is slidably arranged in the sleeve slide groove, an inner rod slide groove is arranged in the detection shell, the built-in trigger rod is slidably arranged in the inner rod slide groove, and one end of the built-in trigger rod slides into the built-in sleeve, a front baffle is arranged at the front end of the built-in sleeve, a reset spring is arranged on the outer side of the built-in sleeve, the reset spring is located between the front baffle and the sleeve slide groove, and a conical baffle is arranged on the built-in trigger rod. The built-in trigger rod is sleeved with an ejection spring, and the ejection spring is located between the built-in sleeve and the conical baffle. A limit groove is provided in the detection shell, and the limit piece is slidably arranged in the limit groove. A limit spring and the limit piece are connected in the limit groove, and the sliding direction of the limit piece is perpendicular to the sliding direction of the built-in trigger rod. A limit block is provided on the limit piece, and the limit block is a wedge-shaped block. The inclined surface on the limit block is in the same direction as the inclined surface of the conical baffle. A control switch is provided on the top of the inner rod sliding groove, a push rod is provided on the front baffle, and a top groove is provided on the limit piece. The positions of the push rod and the top groove correspond to each other, and the contact surface between the top groove and the push rod is an inclined surface, and the contact rod passes through the detection shell and is connected with the front baffle.
[0011] Since fat is softer, it deforms more when squeezed, while lean meat is firmer and deforms less when squeezed. The different characteristics of the meat quality of lean meat and fat meat are utilized to drive the meat quality detection mechanism for detection through the detection hydraulic rod. After the contact rod contacts the meat tissue, it pushes the front baffle and the built-in sleeve to shrink and slide upward, thereby squeezing the reset spring. At the same time, the built-in sleeve slides up to squeeze the ejection spring. At the same time, in the process of the built-in sleeve sliding upward, the push rod penetrates into the top groove, and the inclined surface of the top groove is squeezed to make the limit piece retract into the limit groove and squeeze the limit spring. The conical baffle loses the obstruction of the limit piece, and the ejection spring ejects the built-in trigger rod, thereby triggering the control switch. Therefore, the control switch and the rotary drive motor are controlled and connected, and the meat cutting operation is controlled by the control switch.
[0012] Since the detection hydraulic rod drives the meat quality detection mechanism to extend by the same amplitude each time, when it contacts the lean meat, the deformation of the lean meat caused by the contact rod is small, thereby generating a reaction force to push the built-in sleeve upward, and the meat quality detection mechanism performs a series of operations to trigger the control switch;
[0013] When it comes into contact with fat, the fat will deform greatly, and the contact rod will sink into the fat. It will not produce any reaction force on the contact rod, and will not trigger the control switch, thereby achieving the purpose of cutting only lean meat. A meat quality detection mechanism is set up, which can automatically distinguish between fat and lean meat by pressing, thereby controlling automatic cutting and sampling.
[0014] Furthermore, in order to reset the built-in trigger rod, a reset hydraulic rod is provided in the detection shell, and the control switch is connected to the reset hydraulic rod. When the control switch is triggered, the rotation drive motor is controlled to start cutting, and the reset hydraulic rod is controlled to start at the same time. The reset hydraulic rod pushes the conical baffle to make the built-in trigger rod extend into the built-in sleeve. When the conical baffle passes through the limit piece, since the contact surfaces of the conical baffle and the limit block of the limit piece are both inclined surfaces, the limit piece is squeezed. After the conical baffle passes through the limit piece, the top surface of the conical baffle is limited by the limit piece again, and the initial state is restored, so that subsequent detection can be carried out.
[0015] Furthermore, a clamping shell is provided at the bottom of the sampling main rod, and the sampling clamp is arranged in the clamping shell. The sampling clamp includes a clamping hydraulic rod, clamping claws, side plates and a connecting middle plate. The side plates are arranged on both sides of the connecting middle plate. The side plates and the connecting middle plate are fixed in the clamping shell. The middle ends of the clamping claws are hinged on both sides of the side plates. The two ends of the clamping hydraulic rod are respectively hinged to the tops of the two clamping claws. The clamping claws extend out of the clamping shell, and a detection hole for contacting the rod to extend is provided in the center of the connecting middle plate.
[0016] Furthermore, since the distribution of fat and lean meat is irregular, when selecting lean meat on the meat tissue, the contact rod needs to be able to move to various positions on the meat tissue. The sampling mechanism is connected with an omnidirectional moving mechanism, including a mechanism top plate, a linkage worm gear 1, a linkage worm gear 2, a worm wheel, a transverse slider, a longitudinal gear and a longitudinal sliding frame. The mechanism top plate is arranged on the sampling hydraulic rod. Four moving support plates are arranged on the mechanism top plate. The linkage worm gear 1 and the linkage worm gear 2 are both rotatably arranged on the mechanism top plate and are respectively located on both sides of the mechanism top plate. A transverse sliding bar is arranged on the moving support plate. The transverse slider is slidably arranged on the transverse On the sliding rod, the worm wheel is rotatably arranged on the transverse sliding block, the worm wheel is located between the linkage worm gear one and the linkage worm gear two, and the worm wheel and the linkage worm gear one and the linkage worm gear two are all meshingly connected, the longitudinal gear is rotatably arranged on the transverse sliding block, the longitudinal gear and the worm wheel are coaxial, the longitudinal sliding frame is slidably arranged on the transverse sliding block, the sliding directions of the longitudinal sliding frame and the transverse sliding block are perpendicular to each other, the longitudinal sliding frame is provided with a longitudinal rack, the longitudinal rack is meshed with the longitudinal gear, the linkage worm gear one is connected with a moving motor one, the linkage worm gear two is connected with a moving motor two, and the sampling main rod is arranged on the longitudinal sliding frame.
[0017] Furthermore, the multi-dimensional shaking mechanism includes a shaking hydraulic rod, a shaking support plate, a self-rotating rod, a swing rod, a shaking clamp, a rotating drive block and a rotating connecting block, the shaking support plate is arranged on the shaking hydraulic rod, the rotating connecting block is rotatably arranged on the shaking support plate, the self-rotating rod is rotatably arranged on the rotating connecting block, one end of the swing rod is a rotating end, and the rotating end is rotatably arranged on the shaking support plate, the rotating drive block is rotatably connected to the other end of the swing rod, the self-rotating rod passes through the rotating drive block, a shaking motor is arranged on the shaking support plate, the shaking motor is connected to the rotating end of the swing rod, the shaking clamp is arranged on the self-rotating rod, the test tube to be tested is clamped by the shaking clamp, the shaking motor is started, the swing rod is driven to rotate, and then the swing rod drives the rotating drive block to rotate, and then drives the self-rotating rod to swing, the shaking clamp and the test tube thereon perform a swinging motion together, thereby producing a shaking and oscillating effect on the test tube.
[0018] In order to further improve the shaking effect on the test tube, a spiral groove is provided on the rotation rod, and a guide slider is provided in the rotation drive block. The guide slider is slidably adapted in the spiral groove of the rotation rod. When the rotation drive block rotates with the rotation of the swing rod, the rotation drive block slides relative to the rotation rod, and then the spiral groove is driven by the guide slider, so that the rotation rod rotates, and then the shaking clamp and the test tube rotate while swinging, thereby improving the mixing effect of the sample in the test tube.
[0019] Furthermore, when shaking the test tube, the cap of the test tube needs to be fastened. In order to maintain the stability of the test tube, a test tube placement slot is provided on the test tube placement table, and a clamping plate is provided in the test tube placement slot. In order to improve the accuracy of the sampling clamp in picking up the test tube cap, a cap placement slot is provided on the test tube placement table.

[0051] In order to automatically distinguish lean meat from fat meat, the internal cavity 19 is provided with a meat quality detection mechanism 29, such as Figure 7-8The meat quality detection mechanism 29 includes a detection hydraulic rod 30, a contact rod 31, a built-in sleeve 32, a built-in trigger rod 33, a detection shell 34 and a limiter 35. The detection shell 34 is arranged on the detection hydraulic rod 30. A sleeve slide groove 36 is arranged in the detection shell 34. The built-in sleeve 32 is slidably arranged in the sleeve slide groove 36. An inner rod slide groove 37 is arranged in the detection shell 34. The built-in trigger rod 33 is slidably arranged in the inner rod slide groove 37, and one end of the built-in trigger rod 33 slides into the built-in sleeve 32. A front baffle plate 38 is arranged at the front end of the built-in sleeve 32. A reset spring 39 is sleeved on the outer side of the built-in sleeve 32. The reset spring 39 is located between the front baffle plate 38 and the sleeve slide groove 36. A conical baffle plate 40 is arranged on the built-in trigger rod 33. A ejection spring 41 is sleeved on the built-in trigger rod 33. The ejection spring 41 is located between the built-in sleeve 32 and the conical baffle 40, a limit groove 42 is provided in the detection shell 34, the limit member 35 is slidably arranged in the limit groove 42, a limit spring 43 is provided in the limit groove 42 and connected to the limit member 35, the sliding direction of the limit member 35 is perpendicular to the sliding direction of the built-in trigger rod 33, a limit block 44 is provided on the limit member 35, the limit block 44 is a wedge block, the inclined surface on the limit block 44 is in the same direction as the inclined surface of the conical baffle 40, a control switch 45 is provided on the top of the inner rod sliding groove 37, a push rod 46 is provided on the front baffle 38, a top groove 47 is provided on the limit member 35, the push rod 46 and the top groove 47 are in corresponding positions, the contact surface between the top groove 47 and the push rod 46 is an inclined surface, and the contact rod 31 passes through the detection shell 34 and is connected with the front baffle 38.
[0052] Since fat meat is relatively soft, it deforms more when squeezed, while lean meat is relatively firm and deforms less when squeezed. By utilizing the different characteristics of the meat quality of lean meat and fat meat, the meat quality detection mechanism 29 is driven for detection by the detection hydraulic rod 30. After the contact rod 31 contacts the meat tissue, the front baffle plate 38 and the built-in sleeve 32 are pushed to shrink and slide upward, thereby squeezing the reset spring 39. At the same time, the built-in sleeve 32 slides up to squeeze the ejection spring 41. At the same time, during the upward sliding process of the built-in sleeve 32, the top rod 46 penetrates into the top groove 47. By squeezing the inclined surface of the top groove 47, the limit member 35 is retracted into the limit groove 42 and the limit spring 43 is squeezed. The conical baffle plate 40 loses the obstruction of the limit member 35, and the ejection spring 41 ejects the built-in trigger rod 33, thereby triggering the control switch 45. Therefore, the control switch 45 is controlled and connected to the rotary drive motor 28, and the meat cutting operation is controlled by the control switch 45.
[0053] Since the detection hydraulic rod 30 drives the meat quality detection mechanism 29 to extend by the same amplitude each time, when the contact rod 31 contacts the lean meat, the deformation of the lean meat caused by the contact rod 31 is small, thereby generating a reaction force to push the built-in sleeve 32 upward, and the meat quality detection mechanism 29 performs a series of operations to trigger the control switch 45;
[0054] When contacting fat, the fat is deformed greatly, and the contact rod 31 will sink into the fat, and no reaction force will be generated on the contact rod 31, and the control switch 45 will not be triggered, thereby achieving the purpose of only cutting lean meat. The meat quality detection mechanism 29 is set, and the effect of automatically distinguishing fat and lean meat can be achieved by pressing only, thereby controlling automatic cutting and sampling.
[0055] In a specific implementation, the meat tissue to be tested can be cut into pieces of fixed size and thickness using an automatic meat cutter, so that a uniform standard can be maintained during testing, thereby improving the accuracy of the test.
[0056] In order to reset the built-in trigger rod 33, a reset hydraulic rod 48 is provided in the detection shell 34, and the control switch 45 is connected to the reset hydraulic rod 48. When the control switch 45 is triggered, the rotation drive motor 28 is controlled to start cutting, and the reset hydraulic rod 48 is controlled to start at the same time. The reset hydraulic rod 48 pushes the conical baffle 40 to make the built-in trigger rod 33 extend into the built-in sleeve 32. When the conical baffle 40 passes through the limiter 35, since the contact surfaces of the limit blocks of the conical baffle 40 and the limiter 35 are both inclined surfaces, the limiter 35 is squeezed. After the conical baffle 40 passes through the limiter 35, the top surface of the conical baffle 40 is limited by the limiter 35 again, and the initial state is restored, so that subsequent detection can be carried out.
[0057] The bottom of the sampling main rod 13 is provided with a clamping shell 49, and the sampling clamp 14 is arranged in the clamping shell. Fig. 9 The sampling clamp 14 includes a clamping hydraulic rod 50, a clamping claw 51, a side plate 52 and a connecting middle plate 53.

The middle ends of the clamping claws 51 are hinged on both sides of the side plates 52. The two ends of the clamping hydraulic rod 50 are respectively hinged to the tops of the two clamping claws 51. The clamping claws 51 extend out of the clamping shell 49. A detection hole 54 for the contact rod 31 to extend is provided in the center of the connecting middle plate 53.
[0058] Since the distribution of fat and lean meat is irregular, when selecting lean meat on the meat tissue, the contact rod 31 needs to be able to move to various positions on the meat tissue. The sampling mechanism 2 is connected with an omnidirectional moving mechanism 55, including a mechanism top plate 56, a linkage worm 1 57, a linkage worm 2 58, a worm wheel 59, a transverse slider 60, a longitudinal gear 61 and a longitudinal sliding frame 62. The mechanism top plate 56 is arranged on the sampling hydraulic rod 12. Four moving support plates 63 are arranged on the mechanism top plate 56.

The longitudinal gear 61 is rotatably arranged on the transverse slider 60, and the longitudinal gear 61 and the worm wheel 59 are coaxial. The longitudinal sliding frame 62 is slidably arranged on the transverse slider 60, and the sliding directions of the longitudinal sliding frame 62 and the transverse slider 60 are perpendicular to each other. The longitudinal sliding frame 62 is provided with a longitudinal rack 65, and the longitudinal rack 65 is meshed with the longitudinal gear 61. The linkage worm gear 1 57 is connected with a moving motor 1 66, and the linkage worm gear 2 58 is connected with a moving motor 2 67. The sampling main rod 13 is arranged on the longitudinal sliding frame 62.
[0059] like Fig.11 The multi-dimensional shaking mechanism 3 includes a shaking hydraulic rod 68, a shaking support plate 69, a self-rotating rod 70, a swing rod 71, a shaking clamp 72, a rotation driving block 73 and a rotation connecting block 74. The shaking support plate 69 is arranged on the shaking hydraulic rod 68, the rotation connecting block 74 is rotationally arranged on the shaking support plate 69, the self-rotating rod 70 is rotationally arranged on the rotation connecting block 74, one end of the swing rod 71 is a rotation end 75, and the rotation end 75 is rotationally arranged on the shaking support plate 69, and the rotation driving block 73 is rotationally connected to the swing rod 71 At the other end, the rotation rod 70 passes through the rotation driving block 73, and a shaking motor 78 is arranged on the shaking support plate 69. The shaking motor 78 is connected to the rotating end 75 of the swing rod 71. The shaking clamp 72 is arranged on the rotation rod 70, and the test tube to be tested is clamped by the shaking clamp 72. The shaking motor 78 is started to drive the swing rod 71 to rotate, and then the swing rod 71 drives the rotation driving block 73 to rotate, and then drives the rotation rod 70 to swing, and the shaking clamp 72 and the test tube thereon swing together, thereby generating a shaking and oscillating effect on the test tube.
[0060] In order to further improve the shaking effect of the test tube, Figure 11-12The self-rotating rod 70 is provided with a spiral groove 76, and the rotation driving block 73 is provided with a guide slider 77. The guide slider 77 is slidably adapted in the spiral groove 76 of the self-rotating rod 70. When the rotation driving block 73 rotates with the rotation of the swing rod 71, the rotation driving block 73 slides relative to the self-rotating rod 70, and then the spiral groove 76 is driven by the guide slider 77, so that the self-rotating rod 70 rotates, and then the shaking clamp 72 and the test tube rotate while swinging, thereby improving the mixing effect of the sample in the test tube.
[0061] When shaking the test tube, the cap of the test tube needs to be fastened. The test tube placement table 10 is provided with a test tube placement groove 79, and a clamping plate 81 is provided in the test tube placement groove 79. In order to improve the accuracy of the sampling clamp 14 in picking up the test tube cap, the test tube placement table 10 is provided with a cap placement groove 80.
[0062] During the detection process, it is necessary to drip a solution into a test tube or to draw a solution from a test tube for easy detection, so a dripping mechanism 4 is provided. Fig.13 The dripping mechanism 4 includes a dripping hydraulic rod 82, a dropper 83 and an extrusion assembly 84. The extrusion assembly 84 is arranged on the dripping hydraulic rod 82. The extrusion assembly 84 includes an extrusion box 85, an extrusion airbag 86 and an air pump 87. The bottom of the extrusion box 85 is provided with an insertion port 88 for plugging the dropper 83 into the extrusion box 85. The insertion port 88 is provided with a locking ring 89. The locking ring 89 can be an elastic rubber ring for locking the dropper 83 to prevent it from falling. The extrusion airbag 86 is arranged in the extrusion box 85 and is located on both sides of the dropper 83. The air pump 87 is arranged in the extrusion box 85 and is connected to the extrusion airbag 86.
[0063] The dropper 83 is detachable and installable, so it can be replaced at any time. The dropper 83 is controlled to drip and suck liquid by air bag squeezing, which not only realizes automatic operation, but also improves accuracy compared with manual dripping and sucking operations.
[0064] Since pure water needs to be injected into the test tube during detection, a liquid injection mechanism 5 is provided. Fig.14 , including a liquid injection hydraulic rod 90 , a syringe 91 arranged on the liquid injection hydraulic rod 90 , and a syringe pump 92 connected to the syringe 91 .
[0065] The detection box 1 is provided with a sealed door 93 , the sealed door 93 is provided with a visual glass 94 , and the detection box 1 is provided with a lighting system.
[0066] During specific use, the meat product to be tested is placed on the sampling table 9, the test tube is placed on the test tube placement table 10, and pure water is reserved in the syringe 91 of the injection mechanism 5. During testing, the sampling mechanism 2 is controlled to move above the meat product, and the sampling mechanism 2 is controlled to descend to contact the meat product. The detection hydraulic rod 30 is started to drive the contact rod 31 to contact the meat tissue. When contacting fat, the deformation of the fat is large, and the contact rod 31 will sink into the fat, and no reaction force will be generated on the contact rod 31; when contacting lean meat, the deformation caused by the contact rod 31 on the lean meat is small, and then a reaction force is generated to push the contact rod 31 upward. During the detection process, it is necessary to move to various positions of the meat tissue, so the moving motor 1 66 and the moving motor 2 67 are started to move in the opposite direction, which can drive the linkage worm 1 57 and the linkage worm 2 58 to rotate in the opposite direction, thereby driving the worm wheel 59 to rotate, thereby driving the longitudinal gear 61 to rotate, thereby driving the longitudinal rack 65 to slide, and driving the longitudinal sliding frame 62 to move longitudinally, and starting the moving motor 1 66 and the moving motor 2 67 to move in the same direction, thereby driving the linkage worm 1 57 and the linkage worm 2 58 to rotate in the same direction, thereby driving the worm wheel 59 to move relative to the linkage worm 1 57 and the linkage worm 2 58, thereby driving the transverse slider 60 to slide on the transverse slide bar 64, and at the same time the longitudinal sliding frame 62 also slides transversely, thereby realizing the all-round movement of the sampling mechanism 2.
[0067] When the lean meat generates a reaction force on the contact rod 31, the front baffle plate 38 and the built-in sleeve 32 are pushed upward to shrink and slide, thereby squeezing the reset spring 39. At the same time, the built-in sleeve 32 slides upward to squeeze the ejection spring 41. At the same time, during the upward sliding process of the built-in sleeve 32, the top rod 46 penetrates into the top groove 47, and the limit member 35 is retracted into the limit groove 42 by squeezing the inclined surface of the top groove 47, and the limit spring 43 is squeezed. The conical baffle plate 40 loses the obstruction of the limit member 35, and the ejection spring 41 ejects the built-in trigger rod 33, thereby triggering the control switch 45, thereby controlling the start of the rotation drive motor 28 to drive the rotation drive gear 27 to rotate, thereby driving the guide drive sleeve 15 to rotate, and then driving the lifting sampling tube 16 to rotate, so that the annular cutting knife 17 performs a rotational cutting motion. , and then start the lifting motor 22 to drive the lifting drive gear 21 to rotate, and then drive the lifting sampling tube 16 to descend through the lifting control section 18, and then cut the tissue during descent, and then lift the lifting sampling tube 16 after cutting; when the control switch 45 is triggered, the control rotation drive motor 28 is started to cut, and the reset hydraulic rod 48 is controlled to start at the same time. The reset hydraulic rod 48 pushes the conical baffle 40 to make the built-in trigger rod 33 extend into the built-in sleeve 32. When the conical baffle 40 passes through the limiter 35, since the contact surfaces of the limit blocks of the conical baffle 40 and the limiter 35 are both inclined surfaces, the limiter 35 is squeezed. After the conical baffle 40 passes through the limiter 35, the top surface of the conical baffle 40 is limited by the limiter 35 again, and the initial state is restored, so that subsequent detection can be carried out.
[0068] After cutting the meat tissue, the clamping hydraulic rod 50 is started to extend and retract, and its two ends drive the clamping claws 51 to rotate, thereby achieving the clamping effect, and the meat product is clamped by the sampling clamp 14, and the cut tissue is placed in the test tube by controlling the sampling mechanism 2, and the liquid injection mechanism 5 is controlled to inject pure water into the test tube, and then the test tube cover is picked up by the sampling mechanism 2 and covered on the test tube. After the test tube is grabbed by the multi-dimensional shaking mechanism 3, the shaking motor 78 is started to drive the swing rod 71 to rotate, and then the swing rod 71 drives the rotating drive block 73 to rotate, and then drives the rotating rod 70 to swing, and at the same time, the guide slider 77 is used to The driving action of the spiral groove 76 causes the rotating rod 70 to rotate, and the shaking clamp 72 and the test tube thereon rotate while swinging, thereby achieving a multi-dimensional shaking and oscillating effect and improving the mixing effect. The test tube is then placed in a water bath 11, and then the test tube cover is removed. The test liquid is drawn from the test tube through the dripping mechanism 4, and the air bag 86 is squeezed to expand through the air pump 87, thereby squeezing the dropper 83 for suction and dripping operations, and then the drawn test liquid is dripped into the detection port of the veterinary drug detector 6, and then detected by the veterinary drug detector 6 to complete the detection operation.
