Description

Technical Field

[0001] The invention belongs to the technical field of meat detection, and in particular relates to a sampling device for meat detection. Background Art

[0002] With the improvement of people's living standards, meat products such as lamb and pork have become indispensable in life. At the same time, people's quality standards for meat are getting higher and higher. The current national standardization specifications are becoming more and more stringent, and the quality control is becoming more and more stringent. This has led to quality inspection departments often inspecting the meat sold on the market. Before inspecting the meat, it is necessary to use a sampling device to sample the meat.

[0003] For example, a Chinese patent with authorization announcement number CN220039874U discloses a sampling device for meat detection. When in use, the meat sampling barrel assembly is taken out, the internal threaded cap is aligned with the external threaded head, inserted, and tightened, and then the handle is held so that the sampling blade is aligned with the meat product to be detected, and the sampling blade is pressed to insert. Under the pressure cutting of the sampling blade, the meat will be cut and enter the transparent meat sampling barrel. After the meat sampling barrel assembly is pulled out, the sampled meat will be carried with it. At this time, the staff pinches the pressure rod and pushes it downward along the sliding hole. The dredging block is allowed to enter the transparent meat sampling barrel through the sample pushing rod, and the meat product remaining in the transparent meat sampling barrel is pushed out to complete the sampling of the meat. The above device has the following drawbacks: since the height direction of the sampling blade of the above device is consistent with the length direction of the meat sampling tube, after the meat sampling tube is inserted into the meat by the sampling blade, part of the meat enters the meat sampling tube and forms a columnar structure. Since the meat of the columnar structure is not disconnected from the remaining meat, the meat in the meat sampling tube may still be connected to the remaining meat after the meat sampling tube assembly is pulled out, resulting in sampling failure; and the above device cannot effectively collect meat at different levels, resulting in poor meat detection effect. Therefore, it is urgent to study a sampling device for meat detection in order to solve the above problems. Summary of the invention

[0023] Embodiment 1:

[0024] See also Figure 1-2 As shown, the present invention is a sampling device for meat detection, comprising a support base 1; a lifting mechanism 2 is vertically mounted on the upper surface of the support base 1; a shifting mechanism 3 is horizontally mounted on the lifting mechanism 2; and a sampling mechanism 4 is vertically mounted on the shifting mechanism 3. When in use, the meat product to be detected is placed on the upper surface of the support base 1, and the position of the sampling mechanism 4 is adjusted by the shifting mechanism 3, so that the sampling mechanism 4 corresponds to the sampling point position on the meat product, and then the lifting mechanism 2 drives the sampling mechanism 4 to move downward, so that the sampling mechanism 4 is inserted into the meat product. When the sampling mechanism 4 reaches the meat layer to be sampled of the meat product, the lifting mechanism 2 stops moving, and the sampling mechanism 4 starts sampling the meat layer to be sampled, and resets after the sampling mechanism 4 completes sampling, which not only effectively improves the sampling efficiency and effect of the meat product, but also avoids the occurrence of problems such as sampling failure.

[0026] Embodiment 2:

[0027] Based on Example 1, Figure 3-4 As shown, the shift mechanism 3 includes a second screw rod 301 whose two ends are respectively rotatably connected to the two lifting blocks 202; the second screw rod 301 is threadedly connected to the bearing block 302; the bearing block 302 is slidably interspersed with a guide rod 303 parallel to the second screw rod 301; the two ends of the guide rod 303 are respectively bolted to the two lifting blocks 202; one end of the second screw rod 301 is keyed to the third pulley 304; the third pulley 304 is connected to the fourth pulley 305 through a synchronous belt drive; the fourth pulley 305 is keyed to the output shaft of a second servo motor 306; the second servo motor 306 is horizontally bolted to a lifting block 202. When in use, the fourth pulley 305 is driven to rotate by the second servo motor 306, so that the third pulley 304 drives the second screw rod 301 to rotate, so that the bearing block 302 drives the sampling mechanism 4 to adjust its position.

[0028] Among them Figure 4-6As shown, the sampling mechanism 4 includes a positioning column 401 fixed vertically and inserted on the bearing block 302; a sample storage cylinder 402 is vertically arranged below the positioning column 401; the upper port of the sample storage cylinder 402 is threadedly connected to the lower end of the positioning column 401; the lower end of the sample storage cylinder 402 is a conical structure, and the lower end of the sample storage cylinder 402 has a vertically arranged sampling hole 403; a movable rod 404 is slidably inserted in the sampling hole 403; the lower end of the movable rod 404 has a plugging head 405 with a conical structure, and the plugging head 405 can be slidably inserted in the sampling hole 403; the movable rod 404 is inserted in the positioning column 401; third screws 406 are vertically arranged on the opposite sides of the positioning column 401; the lower ends of the two third screws 406 are rotatably connected to the upper surface of the bearing block 302; the two third screws 406 are rotatably connected to the upper surface of the bearing block 302; The screw rods 406 are connected by a transmission block 407; the transmission block 407 and the two third screw rods 406 are threadedly connected; the movable rod 404 and the positioning column 401 are slidably matched; the upper end of the movable rod 404 is bolted to the transmission block 407; the two third screw rods 406 have the same rotation direction; the upper ends of the two third screw rods 406 are keyed to the fifth pulley 408; the two fifth pulleys 408 are connected by a synchronous belt transmission; the upper end of a third screw rod 406 is keyed to the first gear 409; a bracket 410 is vertically arranged on one side of the first gear 409; the bracket 410 is bolted to the bearing block 302; the bracket 410 is vertically bolted to the third servo motor 411; the output shaft of the third servo motor 411 is keyed to the second gear 412 meshing with the first gear 409. During use, when the lifting mechanism 2 drives the sample storage cylinder 402 to move downward, the plugging head 405 is first inserted into the meat product. When the plugging head 405 just reaches the meat layer to be sampled, the third servo motor 411 drives the second gear 412 to rotate, prompting the first gear 409 to drive the two third screws 406 to rotate synchronously via the fifth pulley 408, so that the transmission block 407 drives the plugging head 405 through the sampling hole 403 and moves into the sample storage cylinder 402 via the movable rod 404. Then, as the sample storage cylinder 402 continues to move downward, the meat layer to be sampled will enter the sample storage cylinder 402 through the sampling hole 403. After the sampling is completed, the movable rod 404 is used to drive the plugging head 405 through the sampling hole 403 and move out of the sample storage cylinder 402, so as to cut off the meat sample and keep the meat sample in the sample storage cylinder 402. This not only effectively improves the sampling efficiency, but also avoids problems such as sampling failure.
