[0002] Rice wine generally refers to the wine brewed from rice, with a fragrant, sweet, soft and mellow taste. During the brewing process of rice wine, layered sampling of rice wine is an important means to understand its internal components, microbial distribution and fermentation status. First, the sampling tool is located at different levels to conduct layered sampling of the rice wine in the wine tank, and then the samples from the upper, middle and lower layers are mixed and their physical and chemical indexes, such as alcohol content, sugar content, acidity, etc., are detected to ensure that the quality of the final product meets the quality standards.

[0052] Among them, during the process of the sampling ring 23 rotating around the axis of the annular piece 22, first drive the through hole 231 to align with the inlet 221, then drive the through hole 231 to be located between the inlet 221 and the outlet 222, and finally drive the through hole 231 to align with the outlet 222.

[0053] A chute 241 is opened on the outer surface of the bracket 2. The slide bar 24 is slidably connected to the bracket 2 through the chute 241.

[0054] During the process of the sliding bar 24 sliding along the sliding groove 241, under the limiting effect of the first pushing groove 242, the sliding sliding bar 24 drives the first pushing block 243 and the sampling ring 23 to rotate around the axis of the ring piece 22 through the first pushing groove 242.

[0056] During the process of the rotating rod 25 rotating at the bottom of the bracket 2, under the limiting effect of the second pushing groove 251, the rotating rotating rod 25 drives the second pushing block 252 and the sliding bar 24 to slide along the sliding groove 241 through the second pushing groove 251.

[0058] Among them, the sliding rail 261 includes a fixed-distance sliding groove 2611 and a variable-distance sliding groove 2612, and the fixed-distance sliding groove 2611 and the variable-distance sliding groove 2612 are connected end to end.

[0059] During the process of the slider 262 sliding along the fixed-distance sliding groove 2611, under the limiting effect of the fixed-distance sliding groove 2611, the distance between the slider 262 and the rod body 1 remains unchanged. During the process of the slider 262 sliding along the variable-distance sliding groove 2612, under the limiting effect of the variable-distance sliding groove 2612, the distance between the slider 262 and the rod body 1 first shortens and then increases;

[0060] During the process of the rotating plate 26 rotating around the axis of the rod body 1, under the limiting effect of the sliding rail 261, the rotating sliding rail 261 drives the rotating rod 25 to swing back and forth at the bottom of the bracket 2 through the slider 262.

[0061] A first flat groove 271, a second flat groove 272 and a thread groove 273 are provided on the circumferential surface of the threaded cylinder 27. The bottom end of the first flat groove 271 is communicated with the thread groove 273, and the top end of the second flat groove 272 is communicated with the thread groove 273. A vertical groove 274 is provided on the circumferential surface of the rod body 1. A lifting ring 275 is slidably sleeved on the circumferential outer surface of the threaded cylinder 27. A sliding rod 2751 is fixedly connected to the circumferential inner surface of the lifting ring 275. The sliding rod 2751 is slidably connected inside the first flat groove 271 and the vertical groove 274. An articulated rod 2752 is movably articulated between the circumferential outer surface of the lifting ring 275 and the T-shaped pipe 21.

[0062] It also includes a locking member 28, which includes a slip ring 281. The slip ring 281 is slidably sleeved on the circumferential outer surface of the ring piece 22. A resistance strip 282 is fixedly connected to the side of the slip ring 281 close to the rod body 1. The bottom end of the resistance strip 282 is in resistance to the upper surface of the bracket 2. A gravity block 283 is fixedly connected to the side of the slip ring 281 away from the rod body 1. A U-shaped plug-in 284 is fixedly connected to the outer surface of the sampling ring 23.

[0063] A driving gear 31 is rotatably connected to the inner bottom wall of the mounting sleeve 12, a rotating sleeve 33 is rotatably sleeved on the circumferential outer surface of the rod body 1, the top of the rotating sleeve 33 penetrates the mounting sleeve 12 and is fixedly connected to a driven gear 32, a driving motor 3 is fixedly connected to the circumferential outer surface of the rod body 1, an output end of the driving motor 3 is fixedly connected to the driving gear 31, the driving gear 31 is meshed with the driven gear 32, and the bottom end of the rotating sleeve 33 is fixedly connected to the top of the threaded cylinder 27.

[0064] Multi-area sampling process:

[0065] In practical applications, the rod body 1 is vertically inserted into the fermentation container, and after the sampling tube 11 is at an appropriate height, the driving motor 3 is started. The driving motor 3 drives the driving gear 31 to rotate on the inner bottom wall of the mounting sleeve 12 through the output end. Under the meshing action of the driving gear 31 and the driven gear 32, the driving gear 31 drives the driven gear 32 and the rotating sleeve 33 to rotate around the axis of the rod body 1. The rotating sleeve 33 drives the threaded tube 27 at its bottom end to rotate synchronously, and the threaded tube 27 drives the rotating plate 26 at its bottom end to rotate synchronously. Under the limiting action of the slide rail 261, the rotating rotating plate 26 pushes the slider 262 and the rotating rod 25 on the bracket 2 through the variable pitch slideway 2612. The bottom is rotated by a certain angle. Under the limiting action of the second push groove 251, the rotating rotating rod 25 pushes the second push block 252 and the slide bar 24 to slide a certain distance along the slide groove 241 through the second push groove 251. Under the limiting action of the first push groove 242, the sliding slide bar 24 pushes the first push block 243 and the sampling ring 23 to rotate around the axis of the ring piece 22 by a certain angle through the first push groove 242, so that the sampling ring 23 drives the through hole 231 on its circumferential surface to be aligned with the water inlet 221, and the rice wine in the fermentation container flows to the inside of the sampling ring 23 through the water inlet 221, so that multiple sampling rings 23 are located in multiple areas at the same height inside the fermentation container for sampling.

[0066] After the sampling is completed, the driving motor 3 is started again, thereby driving the sampling ring 23 to rotate around the axis of the ring piece 22 again by a certain angle, and the sampling ring 23 drives the through hole 231 to rotate to the middle position between the water inlet 221 and the water outlet 222, thereby closing the water inlet 221, and taking the rod body 1 out from the inside of the fermentation container along the vertical direction.

[0067] Sample collection process:

[0068] In practical applications, by continuously starting the driving motor 3, the sampling ring 23 is driven to align the through hole 231 with the water inlet 221. At the same time, the slider 262 is slidably connected to the fixed-distance slideway 2611 again. Under the limiting effect of the fixed-distance slideway 2611, the sampling ring 23 is limited to prevent the sampling ring 23 from rotating around the ring piece 22. The rotating threaded cylinder 27 drives the first flat groove 271, the threaded groove 273 and the second flat groove 272 on its circumferential surface to rotate synchronously. Under the combined limiting effect of the first flat groove 271 and the vertical groove 274, the positions of the lifting ring 275 and the slide rod 2751 on the rod body 1 are fixed. During the process of the slide rod 2751 slidingly connecting with the threaded groove 273, under the combined limiting effect of the threaded groove 273 and the vertical groove 274, the slide rod 2751 and the lifting ring 275 move upward in the vertical direction. The lifting ring 275 drives the top of the hinge rod 2752 to move upward, so that the hinge rod 2752 pulls the T-shaped pipe 21 to rotate on the top of the ring plate 13 through its bottom end. The T-shaped pipe 21 drives the ring piece 22 and the sampling ring 23 to rotate upward until the slide rod 2751 slides upward along the threaded groove 273 and is slidably connected to the second flat groove 272. Under the combined limiting effect of the second flat groove 272 and the vertical groove 274, the positions of the lifting ring 275 and the slide rod 2751 on the rod body 1 are fixed again. The lifting ring 275 limits the T-shaped pipe 21 through the hinge rod 2752, so that the T-shaped pipe 21 always maintains a vertical state. Under the action of gravity, the sample in the sampling ring 23 flows into the sampling cylinder 11 along the T-shaped pipe 21 and the connecting water pipe 29 through the water outlet 222, so as to uniformly collect the samples in the multiple sampling rings 23 and detect the samples obtained in the sampling cylinder 11.

[0069] In summary, during the process of sampling with the sampling cylinder 11 located at the center of the fermentation container, by arranging multiple sampling rings 23 to sample in multiple regions at the same level in the fermentation container, the samples obtained in the sampling cylinder 11 can reflect the fermentation conditions in different regions of the fermentation container, thereby reducing the error of the analysis data of the rice wine samples.

[0070] In summary, by adopting the T-shaped pipe 21 and the sampling ring 23, the present application has the following advantages:

[0071] Advantage 1: By controlling the multiple T-shaped pipes 21 to be in a horizontally dispersed state, the multiple T-shaped pipes 21 drive the multiple sampling rings 23 to sample the rice wine in multiple regions at the same level in the fermentation container, thereby reducing the error of the analysis data of the rice wine samples.

[0072] Advantage 2: by controlling the multiple T-tubes 21 to be in a vertically retracted state, under the action of gravity, the sample in the sampling ring 23 flows through the water outlet 222 along the T-tube 21 and the connecting water pipe 29 to the inside of the sampling tube 11, thereby facilitating the unified collection of the samples in the multiple sampling rings 23.

[0073] Advantage three, during the rotation of the sampling ring 23 around the axis of the ring piece 22, the sampling ring 23 drives the U-shaped plug-in 284 on its outer side to rotate synchronously, so that the U-shaped plug-in 284 is aligned with the gravity block 283, and during the rotation of the ring piece 22 and the sampling ring 23 by the T-shaped tube 21, the ring piece 22 drives the slip ring 281 on its circumferential outer surface to rotate upward, and the slip ring 281 drives the resistance bar 282 to separate from the bracket 2, thereby releasing the limit of the slip ring 281 by the bracket 2, and under the action of the gravity block 283 itself, the slip ring 281 and the gravity block 283 slide downward along the axial direction of the ring piece 22, and the gravity block 283 is clamped downward with the U-shaped plug-in 284, thereby limiting the ring piece 22 and the sampling ring 23, preventing the sampling ring 23 from rotating around the axis of the ring piece 22, and thus keeping the water outlet 222 always open.

[0074] Advantage four, by controlling the rotating sleeve 33 to rotate on the rod body 1, the rotating sleeve 33 drives the threaded tube 27 and the rotating plate 26 below it to rotate, thereby completing the sampling process of the sampling ring 23, the closing process of the sampling ring 23, the reopening process of the sampling ring 23 and the transfer process of the sample of the sampling ring 23 to the sampling tube 11 in sequence.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
