Description

Technical Field

[0001] This invention belongs to the field of sample collection technology, and relates to a sample collection device for testing livestock and poultry products, particularly a sample collection device for testing livestock and poultry products that is easy to clean. Background Technology

[0002] Testing of livestock and poultry products is an important means of ensuring food safety and preventing animal diseases. During the testing process, solid tissue samples such as muscle tissue, liver, and kidneys from livestock and poultry need to be collected, pulverized, and temporarily stored for subsequent drug residue testing, pathogen nucleic acid testing, or nutritional component analysis.

[0003] Currently, common sample collection devices on the market are mainly divided into two categories: one is manual sampling tools, such as sampling spoons and sampling tongs, which have simple structures but limited functions and cannot achieve preliminary sample crushing; the other is electric sampling devices, which usually adopt a meat grinder-type or homogenizer-type structure, assembling the collection head, sample chamber and drive handle into one unit through threads or snaps. They have a fixed cutter shaft or auger structure inside, which can complete the sampling and crushing functions at the same time. However, they are not easy to disassemble and clean. At the same time, due to their structural design, there are cleaning dead corners, which can easily lead to fat and connective tissue from livestock and poultry tissue remaining inside the collection head and sample chamber, resulting in sample contamination. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a sample collection device for testing livestock and poultry products that is easy to clean. The technical problem to be solved by this invention is: how to achieve easy disassembly and cleaning while eliminating cleaning dead corners, and preventing fat and connective tissue from livestock and poultry tissues from remaining inside the collection head and sample chamber, thereby preventing sample contamination.

[0005] The objective of this invention can be achieved through the following technical solutions: A sample collection device for testing livestock and poultry products that is easy to clean includes a sample collection head, a sample processing tube, and a shell. One end of the sample collection head is fixed with multiple cutting blades, and the inner wall of the sample collection head is provided with multiple limiting grooves. Multiple limiting rods are fixed on the outer cylindrical surface of the sample processing tube. The limiting rods are slidably connected to the limiting grooves. The sample processing tube is fixed to the other end of the sample collection head through a movable connector. The sample processing tube contains a first fixing ring, which contains multiple third permanent magnets. A connecting rod is fixed to one end of the first fixing ring, and multiple spiral blades are fixed to the outer cylindrical surface of the connecting rod. A round rod is fixed to the other end of the connecting rod, and multiple cutting blades are fixed to the outer cylindrical surface of the round rod. An internally threaded sleeve is fitted and fixed to the outer cylindrical surface of the other end of the sample processing tube, and a screw cap is screwed into the internally threaded sleeve. A rotary motor is fixed inside the housing. A second fixing ring is fixed to the output shaft of the rotary motor, and multiple fourth permanent magnets are fixed inside the second fixing ring. The fourth permanent magnets are magnetically coupled to the third permanent magnet.

[0006] The working principle of this invention is as follows: First, the sample collection head is inserted into the muscle or visceral tissue of the livestock or poultry to be collected. The second fixed ring and the fourth permanent magnet are driven to rotate by the operation of the rotary motor. Then, under the action of magnetic coupling, the third permanent magnet is driven to rotate. The rotation of the third permanent magnet drives the first fixed ring to rotate, thereby driving the connecting rod, the spiral blade, the cutting blade and the round rod to rotate. The livestock or poultry sample is cut by the cutting blade and transported to the tail of the sample processing cylinder by the spiral blade, thus completing the sample collection. During disassembly and cleaning, the sample collection head is pulled out by hand, then the outer shell is separated, and then the cap is unscrewed. The sample processing cylinder is then inverted, allowing the first fixing ring, connecting rod, spiral blade, cutting blade, and round rod to detach from the sample processing cylinder under gravity, thus enabling complete disassembly and separation. This makes the easy-to-clean sample collection device for livestock and poultry product testing easy to disassemble and clean, and eliminates cleaning dead corners. Fat and connective tissue from livestock and poultry tissues will not remain inside the collection head and sample chamber, preventing sample contamination.

[0007] Multiple fastening bolts are fixed on the outer cylindrical surface of one end of the outer shell, and multiple mounting blocks are fixed on the outer cylindrical surface of the sample processing tube. The fastening bolts are bolted to the mounting blocks.

[0008] With the above structure, the outer shell and sample processing cylinder can be disassembled by separating the fastening bolts and the mounting block. The outer shell can also be separated, and all parts except the outer shell can be put into an ultrasonic cleaner for cleaning, increasing the convenience of cleaning.

[0009] The other end of the outer casing has multiple ventilation openings, and two handles are fixed on the outer cylindrical surface of the outer casing.

[0010] Using the above structure, pushing the handle causes the outer shell to push the sample processing tube, which in turn drives the sample collection head to be inserted into the muscle or visceral tissue of the livestock or poultry to be collected.

[0011] The movable connector includes multiple fixing frames, which are fixed to the outer cylindrical surface of the sample collection head. A first permanent magnet is fixed inside the fixing frame, and multiple fixing rods are fixed to the outer cylindrical surface of the sample processing tube. A second permanent magnet is fixed to one end of each fixing rod, and the second permanent magnet is magnetically attracted to the first permanent magnet.

[0012] By adopting the above structure, the first permanent magnet and the second permanent magnet work together to achieve quick plug-in installation and disassembly by taking advantage of magnetic attraction, thereby increasing the convenience of installation and disassembly.

[0013] The limiting groove is slidably connected to a limiting cutting rod. A first cutting ring is fixed at one adjacent end of the multiple limiting cutting rods, and multiple cutting blades are fixed on the inner wall of the first cutting ring. A second cutting ring is fixed at one adjacent end of the multiple cutting blades.

[0014] With the above structure, when the sample collection head is inserted into the animal muscle or visceral tissue to be collected, the animal muscle or visceral tissue is cut into thin strips by the limiting cutting rod, the first cutting ring, the cutting blade and the second cutting ring, which facilitates subsequent cutting, thereby reducing the subsequent cutting pressure and increasing the cutting effect.

[0015] An elliptical cap is fixed to the other end of the round rod, and the elliptical cap is rotatably connected to the inside of the second cutting ring.

[0016] The above structure, in conjunction with the elliptical cap and the second cutting ring, limits the rotational position of the connecting rod and the round rod, preventing them from shifting during rotation.

[0017] The sample processing tube is made of transparent polymer material, and the outer wall of the sample processing tube is laser-etched with capacity graduation lines.

[0018] The above structure, made of transparent polymer material and used in conjunction with the sample processing tube and volume scale, makes it easy for operators to observe and judge the sample collection volume.

[0019] It also includes a stabilizing component, which includes a first fixing frame fixed to the outer wall of the sample collection head and a second fixing frame fixed to the outer wall of the sample processing cylinder. The other end of the first fixing frame has a through groove, and both sides of the through groove have snap-fit ​​holes. A snap-fit ​​rod is slidably connected inside the snap-fit ​​hole, and a compression spring is fixed to one end of the snap-fit ​​rod. Protective frames are fixed to both sides of the first fixing frame, and the other end of the compression spring is fixed inside the protective frame. A retaining ring is fixed to the other end of the second fixing frame, and the retaining ring is slidably connected inside the through groove. The snap-fit ​​rod and the retaining ring are slidably snapped together.

[0020] With the above structure, during the process of inserting the retaining ring into the through groove, the compression pushes the retaining rod to move backward along the retaining hole, thereby pushing the compression spring to contract. At this time, after the retaining ring is fully inserted into the through groove, the spring force of the compression spring pushes the retaining rod into the ring hole of the retaining ring, thereby completing the retaining fixation, which further increases the connection stability of the sample collection head and the sample processing cylinder.

[0021] One end of the snap-fit ​​rod is fixed with a slide bar, which passes through and extends to the outside of the protective frame, and the other end of the slide bar is fixed with a pull ring.

[0022] With the above structure, disassembly can be completed by pulling the pull ring to cause the slide rod to disengage from the snap ring.

[0023] Compared with existing technologies, this easy-to-clean sample collection device for livestock and poultry product testing has the following advantages: This invention allows for complete disassembly and separation of the sample collection head by manually pulling it out, then separating the outer shell, unscrewing the cap, and inverting the sample processing cylinder. This causes the first fixing ring, connecting rod, spiral blade, cutting blade, and round rod to detach from the sample processing cylinder under gravity, making the sample collection device for livestock and poultry product testing easy to disassemble and clean. Furthermore, it eliminates cleaning dead zones, preventing fat and connective tissue from remaining in the collection head and sample chamber, thus preventing sample contamination.

[0024] This invention allows for the disassembly of the outer shell and sample processing cylinder by separating the fastening bolts and the mounting block. In conjunction with the magnetic coupling transmission structure, the outer shell can also be separated, allowing all other parts except the outer shell to be placed into an ultrasonic cleaner for cleaning, thus increasing the convenience of cleaning.

[0025] In this invention, when the sample collection head is inserted into the animal muscle or visceral tissue to be collected, the animal muscle or visceral tissue is cut into thin strips by the limiting cutting rod, the first cutting ring, the cutting blade, and the second cutting ring, which facilitates subsequent cutting, thereby reducing the subsequent cutting pressure and increasing the cutting effect.

[0026] In this invention, during the insertion of the retaining ring into the through groove, the compression pushes the retaining rod to move backward along the retaining hole, thereby pushing the compression spring to contract. At this time, after the retaining ring is fully inserted into the through groove, the spring force of the compression spring pushes the retaining rod into the ring hole of the retaining ring, thereby completing the retaining fixation, and thus further increasing the connection stability between the sample collection head and the sample processing cylinder.

Detailed Implementation

[0035] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0036] like Figures 1-7 As shown, this easy-to-clean sample collection device for testing livestock and poultry products includes a sample collection head 101, a sample processing cylinder 201, and a housing 301. One end of the sample collection head 101 is fixed with multiple cutting blades 102, and the inner wall of the sample collection head 101 is provided with multiple limiting grooves 103. Multiple limiting rods 202 are fixed on the outer cylindrical surface of the sample processing cylinder 201. The limiting rods 202 are slidably connected to the limiting grooves 103. The sample processing cylinder 201 is fixed to the other end of the sample collection head 101 through a movable connector. A first fixing ring 212 is placed inside the sample processing tube 201. Multiple third permanent magnets 213 are fixed inside the first fixing ring 212. A connecting rod 214 is fixed at one end of the first fixing ring 212. Multiple spiral blades 215 are fixed on the outer cylindrical surface of the connecting rod 214. A round rod 216 is fixed at the other end of the connecting rod 214. Multiple cutting blades 218 are fixed on the outer cylindrical surface of the round rod 216. An internal threaded sleeve 205 is sleeved and fixed on the outer cylindrical surface of the other end of the sample processing tube 201. A screw cap 206 is screwed into the internal threaded sleeve 205. A rotary motor 302 is fixed inside the housing 301. A second fixing ring 303 is fixed on the output shaft of the rotary motor 302. A plurality of fourth permanent magnets 304 are fixed inside the second fixing ring 303. The fourth permanent magnets 304 are magnetically coupled to the third permanent magnet 213.

[0037] First, the sample collection head 101 is inserted into the muscle or visceral tissue of the livestock or poultry to be collected. The second fixing ring 303 and the fourth permanent magnet 304 are driven to rotate by the operation of the rotary motor 302. Then, under the action of magnetic coupling, the third permanent magnet 213 is driven to rotate. The rotation of the third permanent magnet 213 drives the first fixing ring 212 to rotate, thereby driving the connecting rod 214, the spiral blade 215, the cutting blade 218 and the round rod 216 to rotate. The livestock or poultry sample is cut by the cutting blade 218 and transported to the tail of the sample processing tube 201 by the spiral blade 215, thus completing the sample collection. During disassembly and cleaning, the sample collection head 101 is pulled out by hand, then the outer shell 301 is separated, and then the cap 206 is unscrewed. The sample processing cylinder 201 is then inverted, allowing the first fixing ring 212, connecting rod 214, spiral blade 215, cutting blade 218, and round rod 216 to detach from the sample processing cylinder 201 under gravity, thus enabling complete disassembly and separation. This makes the easy-to-clean sample collection device for livestock and poultry product testing easy to disassemble and clean, and there are no dead corners for cleaning. Fat and connective tissue from livestock and poultry tissues will not remain inside the collection head and sample chamber, preventing sample contamination.

[0038] Multiple fastening bolts 305 are fixed on the outer cylindrical surface of one end of the outer shell 301, and multiple mounting blocks 207 are fixed on the outer cylindrical surface of the sample processing cylinder 201. The fastening bolts 305 are bolted to the mounting blocks 207.

[0039] In this embodiment, the outer shell 301 and the sample processing tube 201 can be disassembled by separating the fastening bolt 305 from the mounting block 207, so that the outer shell 301 can also be separated, and all parts except the outer shell 301 can be put into the ultrasonic cleaner for cleaning, increasing the convenience of cleaning.

[0040] The other end of the outer casing 301 has multiple ventilation openings 307, and two handles 306 are fixed on the outer cylindrical surface of the outer casing 301.

[0041] In this embodiment, by pushing the handle 306, the outer shell 301 pushes the sample processing tube 201, causing the sample collection head 101 to be inserted into the animal muscle tissue or internal organ tissue to be collected.

[0042] The movable connector includes multiple fixing frames 104, which are fixed to the outer cylindrical surface of the sample collection head 101. A first permanent magnet 105 is fixed inside the fixing frame 104. Multiple fixing rods 203 are fixed to the outer cylindrical surface of the sample processing tube 201. A second permanent magnet 204 is fixed to one end of the fixing rod 203. The second permanent magnet 204 is magnetically attracted to the first permanent magnet 105.

[0043] In this embodiment, the first permanent magnet 105 and the second permanent magnet 204 are used together to achieve quick plug-in installation and disassembly by means of magnetic attraction, thereby increasing the convenience of installation and disassembly.

[0044] The limiting groove 103 is internally connected to a limiting cutting rod 209. A first cutting ring 208 is fixed at one adjacent end of the multiple limiting cutting rods 209, and multiple cutting blades 210 are fixed on the inner wall of the first cutting ring 208. A second cutting ring 211 is fixed at one adjacent end of the multiple cutting blades 210.

[0045] In this embodiment, when the sample collection head 101 is inserted into the animal muscle tissue or visceral tissue to be collected, the animal muscle tissue or visceral tissue is cut into thin strips by the limiting cutting rod 209, the first cutting ring 208, the cutting blade 210 and the second cutting ring 211, which facilitates subsequent cutting, thereby reducing the subsequent cutting pressure and increasing the cutting effect.

[0046] An elliptical cap 217 is fixedly provided at the other end of the round rod 216, and the elliptical cap 217 is rotatably connected to the inside of the second cutting ring 211.

[0047] In this embodiment, the elliptical cap 217 and the second cutting ring 211 are used in conjunction to limit the rotational position of the connecting rod 214 and the round rod 216, preventing the round rod 216 and the connecting rod 214 from shifting during rotation.

[0048] The sample processing tube 201 is made of transparent polymer material, and the outer wall of the sample processing tube 201 is laser-etched with capacity scale lines.

[0049] In this embodiment, the sample processing tube 201, made of transparent polymer material, is used in conjunction with the volume scale lines to facilitate the operator's observation and judgment of the sample collection volume.

[0050] It also includes a stabilizing component, which includes a first fixing frame 401 fixed to the outer wall of the sample collection head 101 and a second fixing frame 402 fixed to the outer wall of the sample processing cylinder 201. The other end of the first fixing frame 401 is provided with a through groove 403, and both sides of the through groove 403 are provided with snap-fit ​​holes 405. A snap-fit ​​rod 406 is slidably connected inside the snap-fit ​​hole 405, and a compression spring 407 is fixed to one end of the snap-fit ​​rod 406. Both sides of the first fixing frame 401 are provided with protective frames 408, and the other end of the compression spring 407 is fixed inside the protective frame 408. The other end of the second fixing frame 402 is provided with a retaining ring 404, and the retaining ring 404 is slidably connected inside the through groove 403. The snap-fit ​​rod 406 and the retaining ring 404 are slidably snapped together.

[0051] In this embodiment, during the process of inserting the retaining ring 404 into the through groove 403, the compression pushes the retaining rod 406 to move backward along the retaining hole 405, thereby pushing the compression spring 407 to contract. At this time, after the retaining ring 404 is fully inserted into the through groove 403, under the elastic force of the compression spring 407, the retaining rod 406 is pushed into the annular hole of the retaining ring 404, thereby completing the retaining fixation, thereby further increasing the connection stability of the sample collection head 101 and the sample processing cylinder 201.

[0052] One end of the snap-fit ​​rod 406 is fixed with a slide rod 409, which passes through and extends to the outside of the protective frame 408, and the other end of the slide rod 409 is fixed with a pull ring 410.

[0053] In this embodiment, during disassembly, the sliding rod 409 is pulled by the pull ring 410 to cause the locking rod 406 to disengage from the locking ring 404, thus completing the disassembly.

[0054] Working principle of the invention: During collection, the sample collection head 101 is first inserted into the animal muscle or visceral tissue to be collected. The animal muscle or visceral tissue is cut into thin strips by the limiting cutting rod 209, the first cutting ring 208, the cutting blade 210, and the second cutting ring 211. Then, the second fixing ring 303 and the fourth permanent magnet 304 are driven to rotate by the rotary motor 302. In turn, the third permanent magnet 213 is driven to rotate under the action of magnetic coupling. The rotation of the third permanent magnet 213 drives the first fixing ring 212 to rotate, thereby driving the connecting rod 214, the spiral blade 215, the cutting blade 218, and the round rod 216 to rotate. The animal sample is cut by the cutting blade 218 and transported to the tail of the sample processing tube 201 by the spiral blade 215, thus completing the sample collection. During disassembly and cleaning, pull the pull ring 410 to cause the slide rod 409 to drive the snap rod 406 to disengage from the snap ring 404, then pull out the sample collection head 101 by hand, then separate the outer shell 301, then unscrew the cap 206, and invert the sample processing cylinder 201 so that the first fixing ring 212, connecting rod 214, spiral blade 215, cutting blade 218 and round rod 216 detach from the sample processing cylinder 201 under the action of gravity, thus completely disassembling and separating them.

[0055] In summary, by setting up a detachable sample collection head 101, sample processing cylinder 201, and outer shell 301, and by adopting a magnetic coupling transmission method instead of the traditional mechanical transmission for sample processing and collection, this easy-to-clean sample collection device for livestock and poultry product testing is easy to disassemble and clean, and there are no dead corners for cleaning. Fat and connective tissue in livestock and poultry tissues will not remain inside the collection head and sample chamber, preventing sample contamination.

[0056] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
