Description

Technical Field

[0001] This utility model relates to the technical field of liquor fermentation equipment, specifically a cellar stratified sampling device. Background Technology

[0002] In the process of Baijiu brewing, in-depth analysis of the physicochemical properties (such as acidity, starch content, moisture, and microbial community) of the mash at different depths within the fermentation pit is crucial for accurately controlling the fermentation process and optimizing process parameters. This requires obtaining samples that truly reflect the state of each layer of mash. However, the long-pole insertion sampler commonly used in existing technologies has significant operational problems: when the sampling rod is extracted from the depths of the fermentation pit and lifted, its outer wall inevitably scrapes and adheres to the pit wall soil or the upper layer of mash. More critically, these pit wall impurities adhering to the sampler's outer wall (such as microbial-rich pit mud or upper layers of mash in different states) are easily mixed into the sample to be taken at the target depth during the lifting process, resulting in contaminated samples that cannot purely represent the actual state of the target layer. This leads to distorted test data and seriously misleads subsequent process judgments and parameter adjustments.

[0003] Based on this, a cellar stratification sampling device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0004] The purpose of this invention is to provide a cellar stratified sampling device to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A stratified sampling device for a pit includes: a mounting plate, a sliding bracket, a lifting mechanism, and a stratified isolation component; the sliding bracket is fixedly mounted on the top of the mounting plate; the inner wall of the sliding bracket is slidably provided with a lifting mechanism that is adjustable according to the depth of the pit; the front end of the lifting mechanism is fixedly provided with a stratified isolation component for preventing pollution on the outer wall.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0008] In one alternative embodiment: the lifting mechanism includes a slider that is slidably disposed on the inner wall of a sliding bracket, a screw that is rotatably disposed on the inner wall of the sliding bracket, the slider and the screw being threadedly connected, and a motor that is fixedly disposed on the top of the sliding bracket, the output end of the motor being fixedly connected to the top end of the screw.

[0009] In one alternative: the layered isolation assembly includes a mounting bracket fixedly disposed at the front end of the slider, a sludge scraper fixedly disposed on the outside of the mounting bracket, a scraper ring fixedly disposed at the bottom of the sludge scraper, an elastic scraper fixedly disposed at the bottom of the scraper ring, a sleeve slidably disposed on the inner wall of the sludge scraper, and a sealing ring disposed at the bottom of the sleeve.

[0010] In one alternative: the inner wall of the casing is slidably equipped with a sampling component for precise sampling of the pit mud.

[0011] In one alternative embodiment: the sampling assembly includes a sampling tube slidably disposed on the inner wall of the sleeve, a sampling port being opened on the circumferential surface of the sampling tube, a semi-circular tube being rotatably disposed on the inner wall of the sampling tube, a crank being fixedly disposed on the top of the semi-circular tube, a filter screen being laid on the bottom of the semi-circular tube, and a sealing plug being threadedly installed on the bottom of the sampling tube.

[0012] In one alternative: the inner wall of the sliding bracket is provided with a sliding groove that matches the slider.

[0013] In one alternative: the elastic scraper is tilted at a 65° reverse angle, with the scraper blade pointing towards the direction of sleeve lifting.

[0014] In one alternative, a filter channel is provided at the bottom of the sampling tube.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model achieves precise and flexible adjustment of sampling depth by using a motor-driven screw to raise and lower a slider, adapting to the needs of different pits. The core technology lies in the elastic scraper, with its 65° reverse tilt design, which effectively scrapes away pit mud impurities adhering to the outer wall of the casing during the lifting process. Combined with the sealing effect of the sealing ring, this significantly prevents contamination of the target sample by upper-layer substances, ensuring that the sample accurately reflects the state of the pit mud at that depth, thus solving the key problem of contamination from the outer wall.

[0017] 2. This invention uses a crank handle to control the rotation of a semi-circular tube to open and close the sampling port, allowing for precise sample acquisition at the target depth. A bottom filter and filter channel provide initial filtration. After sampling, the sampling port is immediately closed, and the sampling tube is retracted under the double protection of a sealing plug and a sleeve, forming a reliable internal locking and isolation. This design completely prevents the contamination of substances from different depths during the sampling tube's lifting process, ensuring the purity and representativeness of the sample and laying the foundation for subsequent accurate detection and analysis.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-5 As shown, a cellar stratified sampling device includes an installation plate 1, a sliding bracket 2, a lifting mechanism, and a stratified isolation component; the sliding bracket 2 is fixedly installed on the top of the installation plate 1; the inner wall of the sliding bracket 2 is slidably provided with a lifting mechanism that is adjusted according to the depth of the cellar; the front end of the lifting mechanism is fixedly provided with a stratified isolation component for preventing pollution on the outer wall.

[0026] In one embodiment, such as Figure 2 As shown, the lifting mechanism includes a slider 3 slidably mounted on the inner wall of a sliding bracket 2. A screw 4 is rotatably mounted on the inner wall of the sliding bracket 2. The slider 3 is threadedly connected to the screw 4. A motor 5 is fixedly mounted on the top of the sliding bracket 2, and the output end of the motor 5 is fixedly connected to the top end of the screw 4. A sliding groove adapted to the slider 3 is formed on the inner wall of the sliding bracket 2. The mounting plate 1 is bolted to the wall or edge of the pit. The output end of the motor 5 drives the screw 4 to rotate. Because the slider 3 and the screw 4 are threadedly connected, the screw 4 drives the slider 3 to slide on the inner wall of the sliding bracket 2, thereby flexibly adjusting the height of the sludge scraper 7 according to the depth of the pit, facilitating the insertion of the sleeve 10 into the pit sludge for sampling.

[0027] In one embodiment, such as Figure 3 and Figure 4As shown, the layered isolation assembly includes a mounting bracket 6 fixedly mounted on the front end of the slider 3. A scraper bracket 7 is fixedly mounted on the outside of the mounting bracket 6. A scraper ring 8 is fixedly mounted on the bottom of the scraper bracket 7. An elastic scraper blade 9 is fixedly mounted on the bottom of the scraper ring 8. A sleeve 10 is slidably mounted on the inner wall of the scraper bracket 7. A sealing ring 11 is fitted on the bottom of the sleeve 10. A sampling component for precise sampling of the pit mud is slidably mounted on the inner wall of the sleeve 10. The elastic scraper blade 9 is tilted at a 65° reverse angle, with the blade edge facing the lifting direction of the sleeve 10. The 65° tilt angle can balance the scraping force and elastic deformation, preventing the scraper blade from rolling or getting stuck.

[0028] In one embodiment, such as Figure 5 As shown, the sampling assembly includes a sampling tube 12 slidably disposed on the inner wall of the sleeve 10. A sampling port 13 is provided on the circumferential surface of the sampling tube 12. A semi-circular tube 14 is rotatably disposed on the inner wall of the sampling tube 12. A crank handle 15 is fixedly disposed on the top of the semi-circular tube 14. A filter screen 16 is laid on the bottom of the semi-circular tube 14. A sealing plug 17 is threadedly installed on the bottom of the sampling tube 12. A filter flow channel is provided at the bottom of the sampling tube 12.

[0029] By manually controlling the sleeve 10 to slide downwards along the inner wall of the mud scraper 7 and insert into the pit mud, it reaches the target layer. Once in position, the handle 15 is held to push the sampling tube 12 downwards. Then, the handle 15 and the sampling tube 12 rotate relative to each other. The handle 15 drives the semi-circular tube 14 to rotate, opening the blocked sampling port 13 and allowing the pit mud to be sampled into the sampling tube 12. Then, the semi-circular tube 14 is turned to close the sampling port 13 and retract into the sleeve 10. When the sleeve 10 is lifted upwards and passes through the scraper ring 8, the elastic scraper 9 fully scrapes away the pit mud adhering to the surface of the sleeve 10. At the same time, the sealing ring 11 prevents impurities or pit mud from mixing into the sample to be taken at the target depth, thus preventing the obtained sample from being contaminated.

[0030] The above embodiment discloses a cellar stratified sampling device, wherein a motor 5 drives a screw 4 to rotate, causing a slider 3 threadedly connected to the screw 4 to rise and fall in a sliding groove on the inner wall of a sliding support 2, thereby flexibly adjusting the insertion depth of the sleeve 10 installed at the front end of the slider 3 into the cellar. A sealing ring 11 fitted at the bottom of the sleeve 10 forms a sealing barrier when inserted into the cellar mud, preventing upper impurities from seeping into the target sampling layer. When the sleeve 10 completes sampling and is lifted upwards, the elastic scraper 9 fixed to the bottom of the scraper support 7, due to its 65° reverse tilt design (blade facing the lifting direction), can efficiently scrape away the cellar mud or impurities adhering to the outer wall of the sleeve 10, avoiding cross-contamination during the lifting process.

[0031] During operation, the casing 10 is manually inserted to the target depth, and the sampling tube 12 is pushed downwards to the sampling position. The semi-circular tube 14 is rotated by the crank handle 15 to open the circumferential sampling port 13 of the sampling tube 12. The target layer of silt enters the sampling tube 12 through the sampling port 13 and undergoes preliminary filtration through the bottom filter screen 16 and filter channel. After sampling, the crank handle 15 is rotated in the opposite direction to reset the semi-circular tube 14 and close the sampling port 13, forming internal isolation. The sampling tube 12 is then retracted into the casing 10, and the entire device is then lifted. During this process, the sealing ring 11 and the closed sampling port 13 provide double protection against external contamination, ensuring sample purity.

[0032] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
