Description

Technical Field

[0001] The present invention relates to the technical field of chilled meat quality inspection, and in particular to a sampling device for chilled meat quality inspection. Background Art

[0002] With the development of the economy and the improvement of my country's legal system, various industry standards are becoming more and more standardized to safeguard the quality of various products. Therefore, supervision and inspection are indispensable in all links from raw materials to products. For example, in the storage of fresh meat in the food processing industry, the inspection department has to face frequent daily inspection and monitoring activities. Food quality inspection is an important link to ensure food safety and quality. For consumers, it protects people's health and life safety. Through inspection, unsafe and unqualified food can be excluded from entering the market, allowing consumers to buy and eat food with confidence. For food production companies, inspection helps to ensure stable product quality, enhance corporate reputation and market competitiveness, and promptly discover problems in the production process so that measures can be taken to improve and reduce losses caused by quality problems. When inspecting the quality of fresh meat, it is necessary to sample a part of the fresh meat for quality inspection. However, due to the long-term freezing of fresh meat, the meat near the skin is difficult to reflect the quality of the meat well. Therefore, we proposed a sampling device for fresh meat quality inspection. Summary of the Invention

The bottom of the circular cylinder is provided with a bottom arc hole, and the inner wall of the bottom arc hole is slidably connected to an arc blocking plate, which is used to fully block the bottom arc hole to prevent foreign matter outside the circular cylinder from accidentally penetrating into the interior of the circular cylinder through the bottom arc hole and mixing with the fresh meat, affecting subsequent quality inspection.

[0005] Furthermore, the cleaning component includes an annular concave plate, the top of which is fixedly connected to an electric telescopic rod, and the inner wall of the annular concave plate is fixedly connected to a conical thorn bar, which is inserted into the conical cavity of the annular scraper when it moves downward and performs piercing cleaning to prevent the conical cavity inside the annular scraper from being blocked by fresh meat after long-term use, making it difficult to collect fresh meat; an annular scraper is sleeved and fixedly connected to the outer side of the annular concave plate, and the inner wall of the circular cylinder is scraped and cleaned at all times when the annular scraper moves downward to prevent too much fresh meat collected last time from remaining near the bottom of the inner wall of the circular cylinder and affecting the quality inspection of the fresh meat collected subsequently; a circular through hole is provided on the top of the annular scraper, so The bottom of the annular scraper is fixedly connected to an annular baffle, and an annular baffle is provided at the bottom of the annular scraper to fully wrap and cover the position of the extension spring below the annular scraper, so as to prevent excessive fresh meat from accumulating inside the extension spring after long-term use, causing blockage and affecting its extension or contraction. An annular baffle is provided at the bottom of the annular scraper to limit the arc baffle, so as to prevent the arc baffle from being pushed by foreign objects and moving upward to the inside of the circular cylinder to no longer fully block the bottom arc hole. The top of the electric telescopic rod is fixedly connected to the inner wall of the circular cylinder, the outer side of the annular scraper is slidably connected to the inner wall of the circular cylinder, and the annular baffle is sleeved on the outside of the retraction spring and slidably connected to the retraction spring.

[0006] The present invention has the beneficial effects: 1. The conical thorn plate of the present invention drives the bottom sharp thorns to rotate gradually outward by centrifugal force, tearing the frozen surface of the fresh meat so that the internal fresh meat is exposed to the outside, preventing the meat near the skin of the fresh meat from being difficult to reflect the quality of the meat well due to long-term freezing. By setting the interior of the annular cutting blade as a conical cavity, the space inside the annular cutting blade is reduced so that a certain amount of fresh meat overflows, preventing the annular scraper from cutting the exposed fresh meat and making it difficult to sample and store it. When the conical thorn bar moves downward, it is inserted into the conical cavity of the annular scraper and penetrates into it to clear the blockage, preventing the conical cavity inside the annular scraper from being blocked by fresh meat after long-term use, making it difficult to collect the fresh meat.

[0007] The present invention provides a tearing mechanism, in which the conical thorn plate drives the bottom spikes at the bottom to gradually rotate outwards by the centrifugal force, tearing the frozen surface of the cold fresh meat so that the internal fresh meat is exposed outside, preventing the meat near the skin part of the cold fresh meat from being difficult to reflect the quality of the meat well due to long-term freezing. As the conical thorn plate rotates around the fixed small rod, the bottom spikes drive the torn frozen surface to turn outward as a whole, preventing the bottom sharp point of the conical thorn plate from only tearing a limited area of ​​the cold fresh meat surface and making it difficult to tear the entire surface of the center part outwards. As the conical thorn plate extends outwards, the fan-shaped wave plate covers the area between the two conical thorn plates at all times to block it, preventing a part of the cold meat skin torn on the surface of the cold fresh meat from penetrating from between the two conical thorn plates into the sampling area between the four conical thorn plates. The four conical thorn plates are rotated toward the center until they are in contact with each other by the rotation force of the return spring, preventing the four conical thorn plates from losing the centrifugal force from interfering with each other during normal rotation, forming a closed conical tip at the bottom, which makes it inconvenient for the bottom spikes to be subsequently inserted.

[0008] 3. The present invention provides a meat-taking component, and provides a conical cavity inside the annular cutting blade to reduce the space inside the annular cutting blade so that a certain amount of fresh meat can overflow, thereby preventing the annular scraper from cutting the exposed fresh meat and making it difficult to sample and store it. The bottom arc hole is fully blocked by the arc blocking plate to prevent foreign matter outside the circular cylinder from accidentally penetrating into the circular cylinder through the bottom arc hole and mixing with the fresh meat, thereby affecting subsequent quality inspection. The elastically connected arc blocking plate is fixed and limited by arranging a thin sleeve on the inner side of the extension spring to slide with the fixed penetration rod to prevent the arc blocking plate from being offset or misplaced by the elastic connection when moving up and down, making it difficult to fully block the bottom arc hole. A circular slider is provided at the bottom of the fixed penetration rod to resist and limit the gradually downwardly moving thin sleeve to prevent the thin sleeve from disengaging from the sliding limit of the fixed penetration rod when the downward distance is too long and it is difficult to penetrate and cooperate with it.

[0009] The scraper blade is provided with a cleaning component, and when the annular concave plate moves downward, the conical bar on the inner wall and the annular scraper blade on the outer side move together. When the conical bar moves downward, it inserts into the conical cavity of the annular scraper blade and performs piercing cleaning to prevent the conical cavity inside from being blocked by fresh meat after the annular scraper blade is used for a long time, making it difficult to collect the fresh meat. When the annular scraper blade moves downward, it scrapes and cleans the inner wall of the circular cylinder body at all times to prevent too much fresh meat collected last time from remaining near the bottom of the inner wall of the circular cylinder body, which affects the quality inspection of the fresh meat collected later. By arranging an annular baffle at the bottom of the annular scraper, the position of the extension spring below the annular scraper is fully wrapped and covered, so as to prevent the extension spring from being blocked by excessive fresh meat accumulated inside after long-term use, which affects its extension or contraction. By arranging an annular baffle at the bottom of the annular scraper, the arc baffle is resisted and limited, so as to prevent the arc blocking plate from being pushed by foreign objects and moving upward to the inside of the circular cylinder body and no longer fully blocking the arc hole at the bottom.

[0012] For the first embodiment, please refer to Figure 1-Figure 4 The present invention is a sampling device for testing the quality of fresh meat, comprising: A base 1, with an arc-shaped connecting rod 2 provided on the outer side of the base 1; An annular sleeve plate 3, an electric motor 4 is provided on the inner side of the annular sleeve plate 3; A tearing mechanism 5 is used to tear open the frozen surface of the fresh meat and expose the meat inside; The outer side of the base 1 is fixedly connected to one end of the arc-shaped connecting rod 2, and the end of the arc-shaped connecting rod 2 away from the base 1 is fixedly connected to the outer side of the annular sleeve 3. The annular sleeve 3 is sleeved on the motor 4 and fixedly connected to the motor 4. The drive shaft of the motor 4 is fixedly connected to the top of the tearing mechanism 5. The tearing mechanism 5 includes: A conical pricking plate 501 is used to prick the frozen surface of fresh meat and tear it apart. A fixed long plate 502 is provided on the top of the conical pricking plate 501; The fixed long plate 502 is sleeved on the conical thorn plate 501 and is rotatably connected to the conical thorn plate 501 via a rotating bolt; The top of the base 1 is fixedly connected to a hydraulic push rod 6, and the driving shaft of the hydraulic push rod 6 is fixedly connected to a storage platform 7; The top of the fixed long plate 502 is fixedly connected to a circular connecting plate 503, the bottom of the circular connecting plate 503 is fixedly connected to a meat taking component 504, the bottom of the fixed long plate 502 is fixedly connected to a bottom groove 505, the inner wall of the bottom groove 505 is fixedly connected to a fixed small rod 506, the outer surface of the fixed small rod 506 is sleeved and fixedly connected to a tightening spring 507, the bottom of the conical thorn plate 501 is fixedly connected to a bottom spike 508, and one side of the conical thorn plate 501 is fixedly connected to a fan-shaped wave plate 509; The top of the circular connecting plate 503 is fixedly connected to the driving shaft of the motor 4. A plurality of fixed long plates 502 are provided, and the plurality of fixed long plates 502 are evenly distributed on the bottom of the circular connecting plate 503. A plurality of fan-shaped wave plates 509 are provided, and the plurality of fan-shaped wave plates 509 are respectively distributed on one side of the conical thorn plate 501. The conical thorn plate 501 is sleeved on the fixed small rod 506 and is rotatably connected to the fixed small rod 506. The inner side of the conical thorn plate 501 is fixedly connected to one end of the tightening spring 507. When in use, the cold fresh meat to be sampled is placed on the storage table 7, and the storage table 7 is pushed by the hydraulic push rod 6 to drive the cold fresh meat to move upward and contact the tearing mechanism 5 at the top, so that the tearing mechanism 5 penetrates into the cold fresh meat. At this time, the motor 4 is started to drive the tearing mechanism 5 to rotate. The tearing mechanism 5 with an increasingly faster speed tears the pierced cold fresh meat with the piercing point as the center through centrifugal force, so that the fresh meat part inside the cold fresh meat is exposed. After the exposed fresh meat is cut and sampled through the tearing mechanism 5, the motor 4 is turned off, and the storage platform 7 is driven downward by the hydraulic push rod 6 again to make the cold fresh meat escape from the puncture of the tearing mechanism 5. The storage platform 7 drives the cold fresh meat to move upward until it contacts the bottom spikes 508 and makes the bottom spikes 508 penetrate into the cold fresh meat. Then, the circular connecting plate 503 at the bottom is driven to rotate by the motor 4. When the circular rotating plate rotates, it drives the fixed long plate 502 and the meat taking component 504 at the bottom to rotate together. When the fixed long plate 502 rotates, it drives the conical thorn plate 501 connected by the fixed small rod 506 to rotate together. As the speed increases, the conical thorn plate 501 rotates. The faster the cone thorn plate 501 rotates, the greater the centrifugal force it receives. The cone thorn plate 501 rotates outward around the fixed rod 506 under the action of the centrifugal force. When the cone thorn plate 501 rotates, it drives the return spring 507 on the outside of the fixed rod 506 to rotate and tighten. The cone thorn plate 501 drives the bottom spike 508 at the bottom to gradually rotate outward by the centrifugal force, tearing the frozen surface of the cold fresh meat so that the internal fresh meat is exposed to the outside. As the cone thorn plate 501 rotates around the fixed rod 506, the bottom spike 508 drives the torn frozen surface to turn outward as a whole. When the cone thorn plate 501 rotates outward, it pulls the fan-shaped wave plates 509 on both sides to stretch the wave The fan-shaped wave plate 509 covers and resists the area between the two conical thorn plates 501 at all times as the conical thorn plates 501 extend outward. After the four conical thorn plates 501 tear the surface of the cold fresh meat to produce an area for cutting and sampling by the meat taking component 504, the meat taking component 504 performs circumferential cutting and sampling on the exposed fresh meat. After the fresh meat sampling is completed, the motor 4 is turned off to make the conical thorn plates 501 lose the centrifugal force. At this time, the return spring 507 drives the conical thorn plates 501 to rotate toward the center through the continuously pre-tightened rotation force, and the four conical thorn plates 501 are rotated toward the center until they contact with each other through the rotation force of the return spring 507.

[0013] For the second embodiment, please refer to Figures 1-8The present invention provides a sampling device for inspecting the quality of fresh cold meat: a meat taking component 504 comprises a circular cylinder 5041, an electric push rod 5042 is fixedly connected to the top of the circular cylinder 5041, a cleaning component 5043 is fixedly connected to the inner wall of the circular cylinder 5041, an annular cutting blade 5044 is passed through and fixedly connected to the bottom of the circular cylinder 5041, a bottom-opening arc hole 5045 is opened at the bottom of the circular cylinder 5041, an arc-shaped blocking plate 5046 is slidably connected to the inner wall of the bottom-opening arc hole 5045, a retraction spring 5047 is fixedly connected to the top of the arc-shaped blocking plate 5046, a thin sleeve 5048 is fixedly connected to the top of the thin sleeve 504 8 is penetrated by a fixed penetrating rod 5049 and slidably connected thereto, a circular slider 50410 is fixedly connected to the bottom of the fixed penetrating rod 5049, the top of the electric push rod 5042 is fixedly connected to the bottom of the circular connecting plate 503, two bottom arc holes 5045 are provided, and the two bottom arc holes 5045 are evenly distributed at the bottom of the circular cylinder 5041, the annular cutting blade 5044 is configured as an annular blade having a conical cavity therein, the top of the retraction spring 5047 is fixedly connected to the inner wall of the circular cylinder 5041, the top of the fixed penetrating rod 5049 is fixedly connected to the inner wall of the circular cylinder 5041, and the outer side of the circular slider 50410 is slidably connected to the inner wall of the thin sleeve 5048; The cleaning component 5043 includes an annular concave plate 50431, the top of the annular concave plate 50431 is fixedly connected to an electric telescopic rod 50432, the inner wall of the annular concave plate 50431 is fixedly connected to a conical thorn bar 50433, the outer side of the annular concave plate 50431 is sleeved and fixedly connected to an annular scraper 50434, the top of the annular scraper 50434 is provided with a circular through hole 50435, the bottom of the annular scraper 50434 is fixedly connected to an annular baffle 50436, the top of the electric telescopic rod 50432 is fixedly connected to the inner wall of the circular cylinder 5041, the outer side of the annular scraper 50434 is slidably connected to the inner wall of the circular cylinder 5041, and the annular baffle 50436 is sleeved on the outside of the retraction spring 5047 and slides with the retraction spring 5047 The circular cylinder 5041 is pushed downward by the electric push rod 5042, and the circular cylinder 5041 moves downward, and the annular cutting blade 5044 at the bottom moves together. When the annular cutting blade 5044 moves downward, it contacts the exposed part of the cold fresh meat and cuts it in an annular shape. The cut cold fresh meat is gradually squeezed out by the conical cavity inside the annular cutting blade 5044 and overflows from the top onto the arc-shaped blocking plate 5046 on the inner wall of the circular cylinder 5041. By setting the interior of the annular cutting blade 5044 as a conical cavity, the space inside the annular cutting blade 5044 is reduced, so that a certain amount of fresh meat overflows. After a certain amount of fresh meat is stored in the circular cylinder 5041, the arc-shaped blocking plate 5046 is pushed by the cleaning component 5043. 46 moves downward, and the arc-shaped blocking plate 5046 moves downward, driving the top thin sleeve 5048 to move downward together, and stretching the top retraction spring 5047. When the arc-shaped blocking plate 5046 moves down to the bottom of the circular cylinder 5041, the fresh meat on the arc-shaped blocking plate 5046 can be taken out for subsequent quality inspection. After the fresh meat is taken out, the push of the cleaning component 5043 on the arc-shaped blocking plate 5046 is released. At this time, the retraction spring 5047 drives the top arc-shaped blocking plate 5046 to move up to the bottom arc hole 5045 through the retraction force to block the bottom arc hole 5045. The bottom arc hole 5045 is fully blocked by the arc-shaped blocking plate 5046, and the elastically connected arc blocking plate 5046 is tightened by sliding a thin sleeve 5048 and a fixed through rod 5049 on the inner side of the extension spring. 046 is fixed and limited, and a circular slider 50410 is set at the bottom of the fixed penetrating rod 5049 to resist and limit the gradually downward moving thin sleeve 5048, and the electric telescopic rod 50432 is used to push the annular concave plate 50431 downward. When the annular concave plate 50431 moves downward, it drives the conical thorn bar 50433 on the inner wall and the annular scraper 50434 on the outer side to move together. When the conical thorn bar 50433 moves downward, it inserts into the conical cavity of the annular scraper and performs piercing cleaning. When the annular scraper 50434 moves downward, it scrapes and cleans the inner wall of the circular cylinder 5041 at all times. By setting an annular baffle 50436 at the bottom of the annular scraper 50434, the position of the extension spring below the annular scraper 50434 is fully wrapped and covered.After cleaning is completed, the electric telescopic rod 50432 drives the annular baffle 50436 to move up to a position where the bottom surface is flush with the bottom surface of the inner wall of the circular cylinder 5041. The annular baffle 50436 is set at the bottom of the annular scraper 50434 to prevent the arc baffle from interfering with the position.

[0014] When the present invention is in operation, the cold fresh meat to be sampled is placed on the storage table 7, and the storage table 7 is pushed by the hydraulic push rod 6 to drive the cold fresh meat to move upward and contact the tearing mechanism 5 on the top, so that the tearing mechanism 5 penetrates into the cold fresh meat. At this time, the motor 4 is started to drive the tearing mechanism 5 to rotate. The tearing mechanism 5, which rotates at an increasingly faster speed, tears the penetrated cold fresh meat with the penetration point as the center through centrifugal force, so that the fresh meat part inside the cold fresh meat is exposed. At the same time, the exposed fresh meat is cut and sampled by the tearing mechanism 5, and then the motor 4 is turned off. The storage table 7 is driven downward by the hydraulic push rod 6 again to separate the cold fresh meat from the penetration of the tearing mechanism 5. The storage table 7 drives the cold fresh meat to move upward until it contacts the bottom spikes 508 and the bottom spikes 508 are exposed. The cone thorn plate 501 is driven by the centrifugal force to rotate outward around the fixed small rod 506, and the cone thorn plate 501 is driven by the centrifugal force to rotate outward around the fixed small rod 506. When the cone thorn plate 501 rotates, it drives the return spring 507 on the outside of the fixed small rod 506 to rotate and tighten. The cone thorn plate 501 is driven by the centrifugal force to rotate outward, tearing the frozen surface of the cold fresh meat. As the conical thorn plate 501 rotates around the fixed small rod 506, the bottom spike 508 drives the torn frozen surface to turn outward as a whole. When the conical thorn plate 501 rotates outward, it pulls the fan-shaped wave plates 509 on both sides to stretch in a waveform. As the conical thorn plate 501 stretches outward, the fan-shaped wave plates 509 always cover the area between the two conical thorn plates 501 to resist. When the four conical thorn plates 501 tear the surface of the cold fresh meat into an area for cutting and sampling by the meat taking component 504, the meat taking component 504 performs circumcision sampling on the exposed fresh meat. After the fresh meat sampling is completed, the motor 4 is turned off to make the conical thorn plate 501 lose its centrifugal force. At this time, the return spring 507 drives the conical thorn plate 501 to the center through the continuously pre-tightened rotational force. The four conical thorn plates 501 rotate toward the center until they come into contact with each other through the rotational force of the return spring 507. After the surface of the cold fresh meat is torn, the circular cylinder 5041 is pushed downward by the electric push rod 5042. When the circular cylinder 5041 moves downward, the annular cutting blade 5044 at the bottom is driven to move together. When the annular cutting blade 5044 moves downward, it contacts the exposed part of the cold fresh meat and cuts it in a circular shape. The cut cold fresh meat is gradually squeezed through the conical cavity inside the annular cutting blade 5044 and overflows from above onto the arc-shaped blocking plate 5046 on the inner wall of the circular cylinder 5041. By setting the interior of the annular cutting blade 5044 as a conical cavity, the space inside the annular cutting blade 5044 is reduced, allowing a certain amount of fresh meat to overflow.After a certain amount of fresh meat is stored in the circular cylinder 5041, the cleaning component 5043 pushes the arc-shaped blocking plate 5046 downward. When the arc-shaped blocking plate 5046 moves downward, the thin sleeve 5048 at the top moves downward together, and the retraction spring 5047 at the top is stretched. When the arc-shaped blocking plate 5046 moves down to the bottom of the circular cylinder 5041, the fresh meat on the arc-shaped blocking plate 5046 can be taken out for subsequent quality inspection. After the fresh meat is taken out, the cleaning component 5043 is released from the arc-shaped blocking plate 5046 is pushed, and the retraction spring 5047 drives the top arc plugging plate 5046 to move up to the bottom arc hole 5045 through the retraction force to block the bottom arc hole 5045. The bottom arc hole 5045 is fully blocked by the arc plugging plate 5046. The elastically connected arc plugging plate 5046 is fixed and limited by setting a thin sleeve 5048 on the inner side of the extension spring and slidingly cooperating with the fixed penetrating rod 5049. By setting a circular The slider 50410 is used to resist and limit the thin sleeve 5048 which is gradually moving downward, and the annular concave plate 50431 is pushed downward by the electric telescopic rod 50432. When the annular concave plate 50431 moves downward, the conical thorn bar 50433 on the inner wall and the annular scraper 50434 on the outer side move together. When the conical thorn bar 50433 moves downward, it is inserted into the conical cavity of the annular scraper and penetrates it to clear the blockage. When the annular scraper 50434 moves downward, it constantly pushes the circular cylinder 50 41 is scraped and cleaned by installing an annular baffle 50436 at the bottom of the annular scraper 50434 to completely cover the extension spring located below the annular scraper 50434.
