Abstract
Description
Technical Field
[0001] This utility model relates to the field of food inspection technology, and in particular to a stratified sampling device for food quality inspection. Background Technology
[0002] Food sampling devices are specialized equipment designed to collect representative samples from food. These devices play a vital role in food testing, quality control, and food safety management. Food sampling devices ensure that samples collected from different parts or layers of food are highly representative and accurate, thus providing a reliable data foundation for subsequent analysis, testing, or research.
[0003] The applicant discovered through a search that a Chinese patent discloses "A Layered Sampling Device for Food Quality Inspection," with publication (announcement) number "CN220650183U." This patent mainly uses a driving component to drive the sampling tube, causing it to be inserted into the food. The sampling groove on the sampling tube is used to sample the food. However, in actual use, when the sampling tube is inserted into the food, the sampling groove located at the bottom of the sampling tube will first contact the food and take a sample. However, when the sampling tube is fully inserted, it cannot be guaranteed that the food samples collected by the multiple sampling grooves come from different layers, which may lead to errors in the test results. In addition, when the sampling tube is separated from the food, the food samples in the sampling groove are easy to fall out, which will affect subsequent food testing. Utility Model Content
[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0005] A stratified sampling device for food quality inspection includes a mounting frame. A driving cylinder is mounted on the upper side of the mounting frame. A fixed housing is fixedly connected to the output end of the driving cylinder. A clamping mechanism is provided inside the fixed housing. A sampling rod is provided on the lower side of the fixed housing. Multiple mounting slots are provided inside the sampling rod. A sampling mechanism is provided inside each mounting slot. A rectangular groove is provided inside the sampling rod. A worm gear is rotatably fitted to the inner wall of the rectangular groove. A worm wheel is provided inside the rectangular groove. A knob is fixedly connected to one end of the worm gear. Slots are provided on both sides of the sampling rod.
[0006] Furthermore, the clamping mechanism includes a bidirectional lead screw rotatably fitted on the inner wall of the fixed housing, with two clamping plates threaded onto the bidirectional lead screw, and a locking block fixedly connected to each of the two clamping plates on opposite sides. A drive disk is fixedly connected to one end of the bidirectional lead screw.
[0007] Furthermore, the two clamping plates are slidably fitted on the inner wall of the fixed shell, and the two locking blocks are engaged with the two locking slots.
[0008] Furthermore, the sampling mechanism includes an H-shaped partition fixedly connected to the inner wall of the mounting groove, a threaded rod rotatably fitted to the inner wall of the multiple mounting grooves, multiple drive plates threaded onto the threaded rod, two baffles fixedly connected to the lower side of the drive plates, and multiple sampling ports opened on both sides of the sampling rod.
[0009] Furthermore, the threaded rod is rotatably engaged with the H-shaped partition, the upper end of the threaded rod is rotatably engaged with the upper side of the inner wall of the rectangular groove, the worm gear is mounted on the threaded rod, the baffle is slidably engaged with the inner wall of the H-shaped partition, the baffle is engaged with the sampling port, and the drive plate is slidably engaged with the inner wall of the mounting groove.
[0010] Furthermore, limit grooves are provided on both sides of the inner wall of the plurality of mounting grooves, and limit blocks are fixedly connected to both sides of the drive plate, with the limit blocks slidingly engaged with the inner wall of the limit grooves.
[0011] Furthermore, a connecting groove is provided on the lower side of the fixed shell, and the upper end of the sampling rod is slidably fitted on the inner wall of the connecting groove.
[0012] Furthermore, two fixing plates are fixedly connected to the lower side of the mounting bracket, and anti-slip pads are fixedly connected to the lower side of both fixing plates.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] 1. This utility model, by setting up a sampling mechanism, when the sampling rod is inserted into the food, rotates the knob to drive the baffle, allowing different layers of food to enter multiple installation slots. Then, the knob is reversed to drive the baffle to descend and close the sampling port, thus realizing the sampling of different layers of food. This avoids the mixing of different ingredients in the installation slots, which would affect the detection, and also prevents food samples from falling out, improving the convenience of using the equipment.
[0015] 2. This utility model features a clamping mechanism for locking and limiting the sampling rod, facilitating the disassembly and replacement of the sampling rod. This allows for the replacement of different sampling rods and makes it easier to sample different foods. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0023] like Figure 1-5 As shown, a stratified sampling device for food quality inspection includes a mounting frame 1. A drive cylinder 2 is mounted on the upper side of the mounting frame 1. A fixed housing 3 is fixedly connected to the output end of the drive cylinder 2. A clamping mechanism 4 is provided inside the fixed housing 3. A sampling rod 5 is provided on the lower side of the fixed housing 3. Multiple mounting slots 6 are provided inside the sampling rod 5. A sampling mechanism 7 is provided inside the mounting slots 6. A rectangular groove 8 is provided inside the sampling rod 5. A worm gear 9 is rotatably fitted to the inner wall of the rectangular groove 8. A [missing information - likely a device or mechanism] is provided inside the rectangular groove 8. A knob 11 is fixedly connected to one end of the worm gear 10 and worm 9. The sampling rod 5 has slots 12 on both sides. During operation, it is convenient to seal the sampling port 75 on the sampling rod 5. After the sampling rod 5 is inserted into the corresponding position in the food, the knob 11 is turned to drive the baffle 74, so that the sampling rod 5 can sample different layers in the food. After sampling, the knob 11 is reversed to seal the sampling port 75, which prevents the sampled food from falling out, improves the sampling effect of the food, and facilitates subsequent testing.
[0024] like Figure 2-3As shown, in some embodiments, the clamping mechanism 4 includes a bidirectional lead screw 41 rotatably fitted on the inner wall of the fixed housing 3. Two clamping plates 42 are threaded onto the bidirectional lead screw 41. Each clamping plate 42 has a locking block 43 fixedly connected to one side of its opposite side. A drive disk 44 is fixedly connected to one end of the bidirectional lead screw 41. The two clamping plates 42 are slidably fitted on the inner wall of the fixed housing 3. The two locking blocks 43 engage with two locking slots 12. During operation: when it is necessary to disassemble the sampling rod 5, the drive disk 44 is rotated, which drives the bidirectional lead screw 41 to rotate, thereby driving the two clamping plates 42 to move to both sides. This causes the locking blocks 43 to separate from the locking slots 12, thus separating the sampling rod 5 from the fixed housing 3. This facilitates the disassembly of the sampling rod 5 and improves the ease of use of the equipment.
[0025] like Figure 4-5 As shown, in some embodiments, the sampling mechanism 7 includes an H-shaped partition 71 fixedly connected to the inner wall of the mounting groove 6. A threaded rod 72 is rotatably fitted to the inner wall of multiple mounting grooves 6. Multiple drive plates 73 are threaded onto the threaded rod 72. Two baffles 74 are fixedly connected to the lower side of the drive plates 73. Multiple sampling ports 75 are provided on both sides of the sampling rod 5. The threaded rod 72 is rotatably fitted to the H-shaped partition 71. The upper end of the threaded rod 72 is rotatably fitted to the upper side of the inner wall of the rectangular groove 8. A worm gear 10 is mounted on the threaded rod 72. The baffles 74 are slidably fitted to the inner wall of the H-shaped partition 71 and cooperate with the sampling ports 75. The drive plates 73 are slidably fitted to the inner wall of the mounting groove 6. The inner walls of the multiple mounting slots 6 are provided with limiting slots 13 on both sides. The driving plate 73 is fixedly connected to both sides with limiting blocks 14. The limiting blocks 14 slide in the inner wall of the limiting slots 13. During operation: when the sampling rod 5 is inserted into the food, the knob 11 is turned to drive the worm gear 9 to rotate. Through the transmission of the worm wheel 10, the threaded rod 72 is driven to rotate. The rotation of the threaded rod 72 drives the driving plate 73, so that the driving plate 73 slides in the mounting slot 6 and drives the baffle 74 to rise, so that different layers of food enter the multiple mounting slots 6. Then, the knob 11 is reversed to drive the baffle 74 to descend and close the sampling port 75, so as to realize the sampling of different layers of food.
[0026] like Figure 2-3 As shown, in some embodiments, a connecting groove 15 is provided on the lower side of the fixed shell 3, and the upper end of the sampling rod 5 is slidably fitted on the inner wall of the connecting groove 15. During operation, the connecting groove 15 is used to limit the end of the sampling rod 5 and increase the stability of the connection.
[0027] like Figure 1 As shown, in some embodiments, two fixing plates 16 are fixedly connected to the lower side of the mounting frame 1, and anti-slip pads 17 are fixedly connected to the lower side of both fixing plates 16. During operation, the fixing plates 16 and anti-slip pads 17 are used to fix the mounting frame 1, increasing the stability of the equipment.
[0028] The working principle of this utility model is as follows: When in use, the mounting bracket 1 is placed on both sides of the food. Under the action of the driving cylinder 2, the fixed shell 3 is driven, so that the fixed shell 3 drives the sampling rod 5 to be inserted into the food. When the sampling rod 5 is inserted into the food, the knob 11 is turned. The rotation of the knob 11 drives the worm gear 9 to rotate. When the worm gear 9 rotates, it drives the worm wheel 10 to rotate. The rotation of the worm wheel 10 drives the threaded rod 72 to rotate. The rotation of the threaded rod 72 drives the driving plate 73. The driving plate 73 slides and rises in the mounting groove 6, driving the baffle 74 to rise, so that different layers of food enter multiple mounting grooves 6. Then, the knob 11 is reversed to drive the baffle 74 to descend, closing the sampling port 75, thus realizing the sampling of different layers of food.
[0029] Then, under the action of the drive cylinder 2, the sampling rod 5 is driven to extract from the food. When it is necessary to remove the food sample inside the sampling rod 5, the reverse knob 11 drives the baffle 74 to rise, which facilitates the removal and testing of the food sample in the mounting slot 6. When it is necessary to disassemble the sampling rod 5, the drive disk 44 is rotated, and the drive disk 44 drives the bidirectional lead screw 41 to rotate, which drives the two clamping plates 42 to move to both sides, causing the locking block 43 to separate from the locking slot 12, so that the sampling rod 5 is separated from the fixed shell 3, which facilitates the disassembly of the sampling rod 5.
[0030] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
