Description

Technical Field

[0001] This utility model relates to the field of microbial detection of beef jerky, and in particular to an auxiliary device for microbial detection of beef jerky. Background Technology

[0002] Beef jerky, a traditional flavored meat product beloved by consumers, continues to see increasing market demand due to its unique taste and rich nutritional value. However, beef jerky is highly susceptible to microbial contamination during processing, storage, and transportation, including bacteria, molds, and yeasts. These microorganisms not only affect the quality and flavor of the beef jerky but may also produce harmful metabolites, threatening consumers' health and safety.

[0003] The main auxiliary devices for microbial testing of beef jerky include homogenizers: these are used to homogenize beef jerky samples so that microorganisms are evenly distributed in the sample solution for subsequent testing. Common types include percussion homogenizers and high-speed oscillating homogenizers. Percussion homogenizers involve placing the original sample and liquid or solvent into a homogenizing bag, and then repeatedly hammering it with a hammer plate to generate pressure, cause oscillation, and accelerate mixing, achieving a state in which the microbial components in the solution are evenly distributed.

[0004] However, in actual use, the fixed blade has a single cutting path and cannot quickly adjust the blade position. For beef jerky with severe surface contamination (such as seasonings or microorganisms attached to the edges), it is impossible to achieve sufficient mixing between the edge and the central tissue by adjusting the blade, which will lead to poor sampling randomness and an excessively high proportion of microorganisms, thus masking the true level of bacteria inside. Therefore, based on the above problems, an auxiliary device for microbial detection of beef jerky was developed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an auxiliary device for microbial detection of beef jerky, which aims to solve the problem in the prior art that "the fixed blade has a single cutting path and cannot quickly adjust the blade position".

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary device for microbial detection of beef jerky, comprising a base, a shell fixedly connected to the top of the base, an adjustment mechanism provided inside the shell, and a sampling mechanism provided inside the shell;

[0007] The adjustment mechanism includes an output shaft. A motor is fixedly connected inside the base. An output shaft is fixedly connected to the output end of the motor. An outer connecting cylinder is fixedly connected to the top of the output shaft. A cutting blade is provided on the outer wall of the outer connecting cylinder. A connecting rod is hinged to the outer wall of the cutting blade. A connecting block is hinged to the outer wall of the connecting rod. An upper connecting plate is fixedly connected to the top of the cutting blade. A fixing bolt is threaded to the outer wall of the upper connecting plate. The inner extension end of the fixing bolt is threaded to the inner wall of the outer connecting cylinder.

[0008] As a further description of the above technical solution: the number of cutting blades is six sets, and the six sets of cutting blades are symmetrically arranged at equal intervals on the outer wall of the outer connecting cylinder, and the inner wall of the bottom cutting blade is fixedly connected to the outer wall of the outer connecting cylinder.

[0009] As a further description of the above technical solution: the outer wall of the connecting rod is respectively hinged between the top and bottom of the cutting blade, and the bottom of the fixing bolt is fixedly connected to the top of the cutting blade.

[0010] As a further description of the above technical solution: the top of the outer shell is detachably connected to a cover plate, and the inner wall of the outer shell is provided with a sliding groove.

[0011] As a further description of the above technical solution: the sampling mechanism includes a slider, the outer wall of the slider is slidably connected with a groove, and the outer wall of the slider is fixedly connected with a connecting ring.

[0012] As a further description of the above technical solution: a limiting rod is slidably connected to the top of the outer connecting cylinder, a spring is fixedly connected to the outer wall of the limiting rod, the lower extension end of the spring is fixedly connected to the top of the outer connecting cylinder, an insert rod is inserted into the outer wall of the outer connecting cylinder, and a rectangular block is fixedly connected to the right extension end of the insert rod.

[0013] As a further description of the above technical solution: the outer wall of the rectangular block is inserted into the socket opened between the connecting ring and the outer wall of the sampling tube, the inner wall of the sampling tube is slidably connected to a piston, and the top of the piston is fixedly connected to a connecting rod.

[0014] As a further description of the above technical solution: the outer wall of the sampling tube is provided with a feed inlet, and a scraper is fixedly connected to the outer wall of the sampling tube, with the outer wall of the scraper in contact with the inner wall of the outer shell.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the output shaft is driven by a motor to rotate, which drives the outer connecting cylinder and the cutting blade to rotate at high speed, thereby achieving efficient cutting and crushing of beef jerky and providing uniform samples for microbial testing. When the cutting blade, connecting rod, upper connecting plate and fixing bolt are in cooperation, the top cutting blade is manually adjusted. The connecting rod links multiple sets of blades to lift and lower synchronously to adjust the spacing. After the fixing bolt is tightened, the blade position is locked to meet the requirements of different crushing particle sizes.

[0017] 2. In this utility model, the piston, connecting rod, and sampling tube work together. Pulling the connecting rod drives the piston to move inside the sampling tube, creating negative pressure. The crushed beef jerky is then sucked into the tube through the inlet, achieving standardized and pollution-free sample collection. The outer connecting cylinder, sampling tube, and scraper work together. When the outer connecting cylinder rotates, it drives the scraper on the outer wall of the sampling tube to rotate synchronously, cleaning the inner wall of the outer shell and initially removing residual beef jerky, reducing the burden of manual cleaning.

The top of the cutting blade 413 is fixedly connected to the upper connecting plate 414. The upper connecting plate 414 is used to install the fixing bolt 415 to achieve the positioning of the cutting blade 413 after adjustment. The outer wall of the upper connecting plate 414 is threaded with the fixing bolt 415. After the fixing bolt 415 is tightened, the upper connecting plate 414 can be fixed to the inner wall of the outer connecting cylinder 412 to lock the spacing of the cutting blade 413. The inner extension end of the fixing bolt 415 is threaded. The outer connecting cylinder 412 is connected to the inner wall of the outer connecting cylinder 412. There are six sets of cutting blades 413. The six sets of cutting blades 413 are symmetrically arranged at equal intervals on the outer wall of the outer connecting cylinder 412. The inner wall of the bottom cutting blade 413 is fixedly connected to the outer wall of the outer connecting cylinder 412. The outer wall of the connecting rod 416 is respectively hinged between the top and bottom of the cutting blade 413. The bottom of the fixing bolt 415 is fixedly connected to the top of the top cutting blade 413. The top of the outer casing 2 is detachably connected to the cover plate 3. The inner wall of the outer casing 2 is provided with a sliding groove.

[0028] Reference Figures 4-6The sampling mechanism 5 includes a slider 511, whose outer wall slides within a groove to drive a connecting ring 512 to move up and down. The outer wall of the slider 511 is slidably connected to the groove, and the connecting ring 512 is fixedly connected to it. The connecting ring 512 is used to cooperate with the insertion rod 5111 to fix the sampling tube 513 and moves synchronously with the slider 511. A limit rod 519 is slidably connected to the top of the outer connecting cylinder 412. The limit rod 519 limits the movement trajectory of the sampling mechanism 5 and, in conjunction with the spring 5113, provides a reset. A spring 5113 is fixedly connected to the outer wall of the limiting rod 519. The spring 5113 is fitted onto the limiting rod 519 to buffer the impact force when the sampling mechanism 5 moves. The lower extension end of the spring 5113 is fixedly connected to the top of the outer connecting cylinder 412. An insert rod 5111 is inserted into the outer wall of the outer connecting cylinder 412. The insert rod 5111 passes through the insertion port 516 of the connecting ring 512 and the sampling tube 513 to fix the sampling tube 513. A rectangular block 5112 is fixedly connected to the right extension end of the insert rod 5111. 5112 increases the contact area between the insertion rod 5111 and the insertion port 516 to improve the stability of the sampling tube 513. The outer wall of the rectangular block 5112 is inserted into the insertion port 516 opened between the connecting ring 512 and the outer wall of the sampling tube 513.

The connecting rod 515 is manually pulled by the operator to drive the piston 514 to move up and down inside the sampling tube 513. The outer wall of the sampling tube 513 has a feed inlet 517, which is used to allow the crushed beef jerky to enter the sampling tube 513 when the piston 514 is pulled. The outer wall of the sampling tube 513 is fixedly connected to a scraper 518. When the scraper 518 rotates with the outer connecting cylinder 412, it scrapes the inner wall of the outer shell 2 to clean the residual beef jerky. The outer wall of the scraper 518 is in contact with the inner wall of the outer shell 2.

[0029] Working principle: During use, the motor inside the base 1 drives the output shaft 411 to rotate. When the output shaft 411 rotates, it drives the outer connecting cylinder 412 at the top to rotate. When the outer connecting cylinder 412 rotates, it drives the cutting blade 413 (with the aseptic dilution solution for microorganisms) to cut and crush the beef jerky. When it is necessary to adjust the cutting blade 413, the top cutting blade 413 is manually pulled upward. When the cutting blade 413 moves upward, it drives the connecting rod 416 at the bottom to move the cutting blades 413 connected in sequence upward, thereby adjusting the spacing of the cutting blades 413. After the adjustment is completed, the fixing bolts 415 on the upper connecting plate 414 are manually tightened to fix the cutting blades 413.

[0030] After the beef jerky is crushed, a sampling tube 513 is inserted. The sampling tube 513 is fixed by the insertion rod 5111 at the top of the outer connecting tube passing through the connecting ring 512. Then, the staff manually pulls the connecting rod 515 to move the piston 514 upward, thereby drawing the crushed beef jerky into the sampling tube 513 for subsequent microbial testing. At the same time, a scraper 518 (flexible) is connected to the outer wall of the sampling tube 513. When the motor drives the outer connecting cylinder 412 to rotate, it drives the scraper 518 (flexible) on the back of the sampling tube 513 to thoroughly scrape the inner wall of the outer shell 2, performing preliminary cleaning of the inside of the outer shell 2 to prevent excessive accumulation of beef jerky.
