Detailed implementation manners

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0048] As Figures 1 to 7 shown:

[0049] Embodiment 1: The present invention provides a food sampling device for food safety detection, including a support mechanism 1, a stirring mechanism 2, a detection and sampling mechanism 3, and a stirring barrel assembly 4;

[0050] The support mechanism 1 includes a support component 11, on which a lifting frame component 12 is connected in a limit sliding manner. On one side of the support component 11, a driving component 13 is fixedly installed, and the driving component 13 drives the lifting frame component 12 to move up and down;

[0051] Among them, the lifting frame component 12 is used to carry the mixing barrel component 4 and realizes up and down movement through the drive of the driving component 13, so as to adjust the height of the mixing barrel component 4 and facilitate the mixing component 22 to mix foods at different depths in the mixing barrel;

[0052] The mixing mechanism 2 includes a cover 21 installed on the support component 11, and a mixing component 22 is installed in the middle of the cover 21;

[0053] Among them, the cover 21 is installed on the support component 11 to close the top of the mixing barrel component 4. It is designed with installation interfaces for installing the mixing component 22 and the detection and sampling mechanism 3;

[0054] The detection and sampling mechanism 3 includes a sampling tube component 31 installed on the cover 21, and a cleaning tube component 32 is installed inside the sampling tube component 31;

[0055] The mixing barrel component 4 is placed on the lifting frame component 12;

[0056] The sampling tube component 31 includes a sampling tube body 311, a sampling channel 312 is opened inside the sampling tube body 311, a barrier net 313 is arranged at the lower end of the outside of the sampling tube body 311, and a fixing ear 314 is fixedly connected to the upper end of the outside of the sampling tube body 311;

[0057] Among them, the sampling tube component 31 is installed on the cover 21 and is connected to the outside through a negative pressure suction device. It is designed with a sampling channel 312 for extracting food samples from the mixing barrel component 4. A barrier net 313 is arranged at the lower end of the outside of the sampling tube body 311 to prevent too large food particles from entering the sampling channel 312. The fixing ear 314 is used to fixedly install the sampling tube component 31 on the cover 21;

[0058] The top of the sampling channel 312 is connected to a negative pressure suction device;

[0059] The fixing ear 314 is fixedly installed on the cover 21 through a screw passing through;

[0060] Specifically, an adjusting rod moving groove 315 is also opened inside the sampling tube component 31;

[0061] The cleaning tube component 32 includes an adjusting rod 321. The bottom of the adjusting rod 321 extends out of the sampling tube body 311 and is fixedly connected to a connecting frame 322. On the upper side of one end of the connecting frame 322, a baffle 323 is fixedly connected;

[0062] The adjusting rod 321 is rotatably installed inside the adjusting rod moving slot 315, and the baffle 323 can open and close the blocking net 313;

[0063] Among them, the adjusting rod moving slot 315 provides a rotating space for the adjusting rod 321, enabling it to rotate smoothly and control the opening and closing of the baffle 323;

[0064] The cleaning pipe assembly 32 is installed inside the sampling pipe assembly 31 for cleaning the sampling channel 312. It is designed with an adjusting rod 321. By rotating the adjusting rod 321, the opening and closing of the baffle 323 for the blocking net 313 can be controlled. When the baffle 323 blocks the blocking net 313, the cleaning channel 324 and the sampling channel 312 are connected, and clear water can enter the sampling channel 312 from the cleaning channel 324 for cleaning. After cleaning, the clear water in the cleaning channel 324, the connecting groove 325, the inner channel 317, and the sampling channel 312 can be pumped out through the negative pressure suction device.

[0065] Specifically, a rotating limit slot 316 is further provided at the bottom of the sampling pipe body 311;

[0066] The rotating limit slot 316 limits the rotating amplitude of the connecting frame 322;

[0067] Among them, the rotating limit slot 316 restricts the rotating amplitude of the connecting frame 322, ensuring that the baffle 323 does not exceed the predetermined range during the opening and closing process.

[0068] Specifically, an inner channel 317 is further opened inside the sampling pipe body 311;

[0069] A cleaning channel 324 is further opened inside the adjusting rod 321, and a connecting groove 325 is opened on the outer side of the adjusting rod 321. The cleaning channel 324 and the connecting groove 325 are interconnected;

[0070] When the baffle 323 blocks the blocking net 313, the inner channel 317 and the connecting groove 325 are connected, and further the sampling channel 312 and the cleaning channel 324 are connected;

[0071] When the baffle 323 is away from the blocking net 313, the inner channel 317 and the connecting groove 325 are misaligned.

[0072] Specifically, the top of the adjusting rod 321 extends out of the sampling pipe body 311 and is fixedly connected with a pointer 326;

[0073] The pointer 326 and the connecting frame 322 are in the same direction;

[0074] Among them, the pointer 326 and the connecting frame 322 are in the same direction. By observing the direction of the pointer 326, the staff can conveniently know whether the blocking net 313 is blocked, so as to make timely adjustments.

[0075] As can be seen from the above, during use, the food raw materials to be mixed are simultaneously put into the stirring barrel assembly 4, and then the stirring barrel assembly 4 is placed on the lifting frame assembly 12. The driving assembly 13 is used to drive the lifting frame assembly 12 to move upward to adjust the position of the stirring barrel assembly 4, so as to facilitate the stirring assembly 22 to stir the food at different depths in the stirring barrel assembly 4;

[0076] After stirring for a specified time, when it is necessary to sample and detect the food at a specified depth in the stirring barrel assembly 4, the driving assembly 13 is controlled to make the stirring barrel assembly 4 located at a specified height, and the negative pressure suction device is opened, so that the food near the barrier net 313 can enter the sampling channel 312 through the barrier net 313 and be transferred to the outside for detection. The barrier net 313 can prevent oversized food from entering the sampling channel 312;

[0077] After sampling at the current position is completed, rotate the adjusting rod 321 to make the baffle 323 block the barrier net 313. At this time, the inner channel 317 and the communication groove 325 are communicated, the cleaning channel 324 and the sampling channel 312 are communicated, the cleaning channel 324 is communicated with external clean water, the negative pressure suction device is opened, so that the clean water is introduced from the cleaning channel 324, and then enters the sampling channel 312 through the communication groove 325 and the inner channel 317, and is drawn out from the top by the negative pressure suction device, so as to achieve the cleaning effect. After cleaning, the cleaning channel 324 can be communicated with external air and attracted by the negative pressure suction device, so as to discharge the clean water in the cleaning channel 324, the communication groove 325, the inner channel 317 and the sampling channel 312;

[0078] After cleaning is completed, the staff can adjust the height of the stirring barrel assembly 4 according to needs, so as to sample and detect the food at different positions in the stirring barrel assembly 4;

[0079] The staff can conveniently know whether the barrier net 313 is blocked through the pointing of the pointer 326;

[0080] The rotation amplitude of the connecting frame 322 can be limited by rotating the limiting groove 316.

[0081] As Figure 8 shown:

[0082] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the stirring assembly 22 includes a second motor 221 and a fixed bracket 222. The output end of the second motor 221 is fixedly connected with a stirring rod 223 through a coupling, and the lower end of the stirring rod 223 is fixedly connected with a stirring blade 224;

[0083] The fixed bracket 222 is fixedly installed on the cover 21, and the cover 21 is limited and clamped on the support assembly 11;

[0084] Among them, the second motor 221 serves as the power source of the stirring assembly 22. The second motor 221 is directly connected to the stirring rod 223 through a coupling to provide stable rotational power. When the second motor 221 is started, it drives the stirring rod 223 and the stirring blade 224 to rotate, thereby realizing the mixing and stirring of food;

[0085] The fixing bracket 222 is used to stably install the second motor 221 to ensure that it does not shake or displace during operation. It is fixedly installed on the cover 21, providing a solid support platform for the second motor 221;

[0086] The stirring rod 223 serves as a bridge connecting the second motor 221 and the stirring blade 224, and is responsible for transmitting the rotational power of the motor to the stirring blade 224. The stirring blade 224 is in direct contact with the food, and through the shear force and stirring force generated by its rotation, the food is evenly mixed;

[0087] The cover 21 is limited and embedded on the support assembly 11. This design not only ensures the stable installation of the cover, but also facilitates disassembly and cleaning. At the same time, it also provides a reliable installation foundation for the stirring assembly 22 and the detection and sampling mechanism 3.

[0088] As can be seen from the above, turning on the second motor 221 can cause the stirring rod 223 to drive the stirring blade 224 to rotate, and the rotation of the stirring blade 224 can cause the food in the stirring bucket assembly 4 to be stirred;

[0089] The fixing bracket 222 is fixedly installed on the cover 21, and further fixes the second motor 221;

[0090] The cover 21 is limited and embedded on the support assembly 11 for support and fixation.

[0091] Such as Figure 9 and Figure 10 shown:

[0092] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that the support assembly 11 includes a base 111, a side support arm 112 is fixedly connected to the upper side of one end of the base 111, a protective ring 113 is fixedly connected to one side of the side support arm 112, and a guide rod 114 is also provided on one side of the side support arm 112;

[0093] The lifting frame assembly 12 includes a lifting frame body 121, a guide groove 122 is opened on the upper side of the lifting frame body 121, and a connecting block 123 is fixedly connected to one end of the lifting frame body 121;

[0094] The lifting frame body 121 is slidably embedded on the guide rod 114, and the stirring bucket assembly 4 is limited and embedded on the guide groove 122;

[0095] Among them, the base 111 provides stable support force to ensure that the device does not shake or tilt during operation;

[0096] The side support arm 112 extends from the base 111 and is used to install the protective ring 113, the guide rod 114 and the drive assembly 13. It provides sufficient strength and stability to support the weight and working load of these components;

[0097] The protective ring 113 is installed on one side of the side support arm 112 and is used to limit the position of the stirring barrel body 41 to prevent it from having excessive displacement or shaking during the stirring process. This helps to ensure the uniformity and safety of stirring;

[0098] The guide rod 114 provides a sliding track for the lifting frame assembly 12 to ensure that it moves in a straight line during the up and down movement. This helps to improve the movement accuracy and stability of the lifting frame assembly 12;

[0099] The lifting frame assembly 12 includes a lifting frame body 121, a guide groove 122 and a connecting block 123. The lifting frame body 121 is snap-fitted with the limit bottom plate 42 of the stirring barrel assembly 4 through the guide groove 122 to realize the limitation and support of the stirring barrel assembly 4. The connecting block 123 is fixedly connected with the sliding block of the drive assembly 13 and is used to transmit the driving force and realize the up and down movement of the lifting frame assembly 12;

[0100] The drive assembly 13 includes a ball screw 131, a first motor 132, a first pulley 133, a second pulley 134 and a belt 135. The first motor 132 drives the ball screw 131 to rotate through belt transmission, and the sliding block on the ball screw 131 moves accordingly. Since the sliding block is fixedly connected with the connecting block 123, the lifting frame assembly 12 and the stirring barrel assembly 4 can be driven to move up and down as a whole. This design has the advantages of high transmission efficiency and high positioning accuracy;

[0101] The stirring barrel assembly 4 includes a stirring barrel body 41, a limit bottom plate 42 and a clamping groove 43. The stirring barrel body 41 is used to hold food and stir it; the limit bottom plate 42 is snap-fitted with the guide groove 122 of the lifting frame assembly 12 to realize the limitation and support of the stirring barrel assembly 4; the clamping groove 43 facilitates the operator to carry and install the stirring barrel assembly 4.

[0102] Specifically, the drive assembly 13 includes a ball screw 131 and a first motor 132. One end of the ball screw 131 is fixedly connected with a first pulley 133, the output end of the first motor 132 is fixedly connected with a second pulley 134, the outer sides of the first pulley 133 and the second pulley 134 are jointly sleeved with a belt 135, and a matching sliding block is arranged on the ball screw 131;

[0103] The ball screw 131 is fixedly installed outside the side support arm 112 through bearings, and the first motor 132 is fixedly installed outside the side support arm 112; the sliding block and the connecting block 123 are fixedly connected.

[0104] Specifically, the stirring barrel assembly 4 includes a stirring barrel body 41, a limiting bottom plate 42 is fixedly connected to the bottom of the stirring barrel body 41, and a clamping groove 43 is arranged outside the stirring barrel body 41.

[0105] As can be seen from the above, the limiting bottom plate 42 of the stirring barrel assembly 4 is snapped into the guiding groove 122 of the lifting frame body 121, and at this time, the stirring barrel body 41 is limited;

[0106] Then, start the first motor 132 to make the second pulley 134 rotate. The rotation of the second pulley 134 makes the belt 135 drive the first pulley 133 and the connected ball screw 131 to rotate. The sliding block on the ball screw 131 moves accordingly. Since the sliding block is fixedly connected to the connecting block 123, the entire lifting frame assembly 12 and the stirring barrel assembly 4 are lifted or lowered, realizing the height adjustment of the stirring barrel assembly 4;

[0107] The protective ring 113 can limit the position of the stirring barrel body 41.
