Description

Technical Field

[0001] This application relates to the technical field of solid-state fermentation, and in particular to a solid-state fermentation fixed-point sampling device. Background Technology

[0002] In the field of solid-state fermentation, the analysis of mash samples in fermentation pits is a key step in monitoring the fermentation process and ensuring fermentation quality. By obtaining mash samples from different parts, we can gain a deeper understanding of the uniformity of the fermentation process, the distribution of microorganisms, and the transformation of various substances, thereby providing a basis for optimizing fermentation process parameters.

[0003] However, when using traditional handheld sampling devices that are widely used, operators often need to constantly adjust their posture according to the actual situation when facing fermentation pits of different depths and locations. Sometimes, they even need to use additional tools such as supports to assist in sampling. This not only consumes a lot of physical strength and energy for the operators, and the operation process is cumbersome and inconvenient, but it is also easy to cause sampling deviations due to improper operation, making it impossible to accurately obtain the mash sample from the required location.

[0004] Regarding the aforementioned technologies, the inventors believe that traditional handheld sampling devices have the drawback that when facing fermentation pits of different depths and locations, operators often need to constantly adjust their posture according to the actual situation, and sometimes even need to use additional tools such as supports to assist in sampling. Utility Model Content

[0005] To address the issue that traditional handheld sampling devices often require operators to constantly adjust their posture when facing fermentation pits of varying depths and locations, and sometimes even necessitate the use of additional tools such as supports for sampling, this application provides a fixed-point sampling device for solid-state fermentation.

[0006] This application provides a solid-state fermentation fixed-point sampling device, which adopts the following technical solution:

[0007] A solid-state fermentation fixed-point sampling device, comprising

[0008] A lifting module includes an outer sleeve and an inner sleeve. The outer sleeve is fitted over the inner sleeve. A threaded rod is provided inside the inner sleeve. A driving assembly is installed on the outer sleeve. The driving assembly drives and connects to the threaded rod. The threaded rod is threadedly connected to the inner sleeve. A slider is fitted over the inner sleeve. The inner sleeve and the slider are fixedly connected.

[0009] The sampling module includes a sampling cylinder and a positioning rod. One end of the sampling cylinder is sleeved on the inner sleeve, and the other end is connected to the positioning rod. The sampling cylinder and the inner sleeve are rotatably connected. A scraper is fixedly installed at the bottom of the inner sleeve. The sampling cylinder has a storage cavity and a through groove for the scraper to extend out.

[0010] By adopting the above technical solution, the outer sleeve can protect the internal structure and provide guidance. The inner sleeve is connected to the threaded rod and, driven by the threaded rod, can rise or fall along the axial direction of the outer sleeve. When the drive component drives the threaded rod to rotate, the rotational motion is converted into the linear lifting motion of the inner sleeve by utilizing the transmission principle of the thread. The inner sleeve is connected to the sampling cylinder, which has a storage cavity inside, specifically for collecting and storing the mash samples obtained from the fermentation pit. During sampling, the positioning rod is inserted into the mash in the fermentation pit to provide accurate positioning for the sampling cylinder. The scraper is fixedly installed at the bottom of the inner sleeve. When the inner sleeve descends, the scraper penetrates into the mash in the fermentation pit. The through-slot on the sampling cylinder allows the scraper to extend smoothly and scrape the mash. This sampling device no longer requires frequent adjustments to its own posture or the use of additional tools, greatly saving physical strength and energy and improving the convenience of operation.

[0011] Optionally, the scraper is an arc-shaped scraper, and an angle is provided between the arc-shaped scraper and the outer wall of the inner sleeve.

[0012] By adopting the above technical solution, the arc-shaped scraper can naturally guide the mash to the sampling cylinder. The appropriate angle allows the scraper to apply the best force to the mash when scraping it, ensuring that the mash can be scraped smoothly without causing excessive disturbance to the mash, thus ensuring that the original state and properties of the sample are not affected too much.

[0013] Optionally, the inner sleeve is provided with a snap-fit ​​component, and the sampling cylinder is provided with a groove, the snap-fit ​​component being rotatably installed in the groove.

[0014] By adopting the above technical solution, the groove and the inner sleeve's locking parts cooperate with each other, providing the locking parts with rotation space and track, making the rotation operation of the sampling cylinder smoother, while also limiting the locking parts within a certain range of motion, ensuring the stability and controllability of its rotation.

[0015] Optionally, the bottom of the positioning rod is provided with a pointed tip.

[0016] By adopting the above technical solution, the tip can penetrate the mash more accurately, greatly reducing the resistance when inserting it into the mash.

[0017] Optionally, a handle is installed at one end of the outer sleeve, and the other end is connected to the inner sleeve.

[0018] By adopting the above technical solution, the handle provides an easy gripping part for the operator. When performing operations such as rotating the outer sleeve to control the extension of the scraper and adjusting the height of the sampling device, the operator can apply force more easily by holding the handle.

[0019] Optionally, the drive assembly includes a rotating shaft and a drive source. The drive source is installed outside the outer sleeve and drives the rotating shaft. The rotating shaft passes through the outer sleeve and extends into the interior of the outer sleeve. The rotating shaft is coaxially connected to a first bevel gear. The first bevel gear meshes with a second bevel gear, and the second bevel gear is coaxially connected to the threaded rod.

[0020] By adopting the above technical solution, the drive source drives the rotating shaft to rotate, the rotating shaft drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear that is meshed and connected with it to rotate, and the second bevel gear drives the threaded rod to rotate. Since the threaded rod is threadedly connected to the inner sleeve and the inner sleeve is connected to the slider, the inner sleeve will make a linear up-and-down movement along the axis of the threaded rod, thereby making the sampling cylinder move up and down, realizing the scraping operation of mash at different depths in the fermentation pit.

[0021] Optionally, a limiting plate is fitted onto the threaded rod, and the limiting plate is located between the second bevel gear and the slider.

[0022] By adopting the above technical solution, the limiting plate can effectively limit the axial movement range of the inner sleeve on the threaded rod, preventing the inner sleeve from rising or falling excessively during the lifting process.

[0023] Optionally, the inner sleeve is provided with an internal thread that mates with the threaded rod.

[0024] By adopting the above technical solution, the design of the threaded rod and the inner sleeve can effectively prevent the inner sleeve from shifting or shaking during the lifting process, ensuring that the scraper can always accurately reach the predetermined sampling position, thus improving the accuracy and precision of sampling.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. This solid-state fermentation fixed-point sampling device integrates a lifting module and a sampling module. Through the lifting module, operators can easily adjust the height of the sampling device to adapt to fermentation pits of different depths, eliminating the need for frequent adjustments to their posture or the use of additional tools, greatly saving physical strength and energy, and improving operational convenience. The lifting module solves the problem of inconvenient operation of traditional sampling devices when facing fermentation pits of different depths. The sampling module ensures accurate sampling at different locations. Rotating the outer sleeve controls the extension of the scraper. Positioning rods and efficient scraper collection of mash samples reduce sampling deviation and improve sampling accuracy and reliability.

[0027] 2. During the scraping process of the mash, the arc-shaped scraper acts like a guide plate, allowing the mash to enter the storage chamber of the sampling cylinder more smoothly under the push of the scraper, reducing spillage and loss of mash during the sampling process and improving sampling efficiency.

[0037] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0038] This application discloses a solid-state fermentation fixed-point sampling device, referring to... Figure 1 , Figure 2 and Figure 3 The solid-state fermentation fixed-point sampling device includes a lifting module 1 and a sampling module 2. The lifting module 1 includes an outer sleeve 11 and an inner sleeve 12. The outer sleeve 11 is sleeved outside the inner sleeve 12. A threaded rod 13 is provided inside the inner sleeve 12. A drive assembly 14 is installed on the outer sleeve 11. The drive assembly 14 drives the threaded rod 13. The threaded rod 13 is threadedly connected to the inner sleeve 12. A slider 16 is sleeved on the inner sleeve 12. The inner sleeve 12 and the slider 16 are fixedly connected.

[0039] The sampling module 2 includes a sampling cylinder 21 and a positioning rod 22. One end of the sampling cylinder 21 is sleeved on the inner sleeve 12, and the other end is connected to the positioning rod 22. The sampling cylinder 21 and the inner sleeve 12 are rotatably connected. A scraper 213 is fixedly installed at the bottom of the inner sleeve 12. The sampling cylinder 21 has a storage cavity 211 inside, and a through groove 212 for the scraper 213 to extend out is opened on the sampling cylinder 21.

[0040] In this solid-state fermentation sampling device, the outer sleeve 11 is fitted over the inner sleeve 12. The outer sleeve 11 protects the internal structure and provides guidance, ensuring that the inner sleeve 12 can stably rise and fall along the axial direction of the outer sleeve 11, guaranteeing the smoothness of the entire lifting process. The inner sleeve 12 is threadedly connected to the threaded rod 13, and under the drive of the threaded rod 13, it can rise or fall along the axial direction of the outer sleeve 11. The slider 16 fixedly connected to the inner sleeve 12 further enhances its stability and accuracy during the lifting process, ensuring that the entire sampling device can operate reliably when adjusting the height. In addition, the inner sleeve 12 also serves as the connecting carrier for the sampling module 2, providing a foundation for the installation and rotation of the sampling cylinder 21.

[0041] The threaded rod 13 serves as the core transmission component of the lifting module 1. When the drive assembly 14 drives the threaded rod 13 to rotate, the rotational motion is converted into the linear lifting motion of the inner sleeve 12 by utilizing the transmission principle of the thread. This threaded transmission method has the characteristics of high precision and precise control, and can accurately adjust the height of the inner sleeve 12 according to actual needs to meet the sampling requirements of fermentation pits of different depths.

[0042] The drive assembly 14 provides power for the rotation of the threaded rod 13. The drive assembly 14 can be a motor. By controlling the forward and reverse rotation and speed of the motor, the rotation direction and speed of the threaded rod 13 can be precisely controlled. This allows the operator to flexibly and conveniently adjust the height of the sampling device according to the actual depth of the fermentation pit, which greatly improves the efficiency and convenience of operation and avoids the cumbersome and inconvenient traditional manual operation.

[0043] The slider 16 is sleeved outside the inner sleeve 12 and fixedly connected to the inner sleeve 12. The slider 16 further constrains the movement trajectory of the inner sleeve 12, ensuring that it can only move up and down in a straight line along a predetermined direction.

[0044] One end of the sampling cylinder 21 is fitted onto the inner sleeve 12 and can rotate relative to it. This rotating connection design allows the sampling cylinder 21 to be flexibly adjusted at different angles to meet the sampling needs of different positions and angles. The sampling cylinder 21 has a storage cavity 211 inside, which is specifically used to collect and store the mash samples obtained from the fermentation pit, ensuring that the samples can be safely and completely preserved during the sampling process, facilitating subsequent analysis and testing.

[0045] The positioning rod 22 is connected to the other end of the sampling cylinder 21. During sampling, the positioning rod 22 is inserted into the mash in the fermentation pit, providing accurate positioning for the sampling cylinder 21 and ensuring that each sampling is performed at the predetermined position, effectively improving the accuracy and repeatability of sampling. At the same time, the positioning rod 22 also provides a certain degree of support and fixation, preventing the sampling cylinder 21 from shaking or shifting due to external forces during sampling, thus ensuring the accuracy and reliability of sampling.

[0046] The scraper 213 is fixedly installed at the bottom of the inner sleeve 12. When the inner sleeve 12 descends, the scraper 213 penetrates into the fermentation tank. The through-groove 212 on the sampling cylinder 21 allows the scraper 213 to extend smoothly and scrape the fermented mash. The function of the scraper 213 is to efficiently scrape the fermented mash into the sampling cylinder 21, achieving a fast and complete sampling process. This avoids omissions or incomplete sampling that may occur with manual sampling, thus improving the efficiency and quality of sampling.

[0047] This solid-state fermentation fixed-point sampling device integrates a lifting module 1 and a sampling module 2. Through the lifting module 1, the operator can easily adjust the height of the sampling device to adapt to fermentation pits of different depths, eliminating the need for frequent adjustments to their posture or the use of additional tools, greatly saving physical strength and energy, and improving the convenience of operation. The lifting module 1 solves the problem of inconvenience in operation when facing fermentation pits of different depths with traditional sampling devices. The sampling module 2 ensures accurate sampling at different locations, using positioning rod 22 for positioning and scraper 213 for efficient collection of mash samples, reducing sampling deviation and improving the accuracy and reliability of sampling.

[0048] Through the coordinated work of various components, efficient, accurate, and convenient point sampling is achieved in solid-state fermentation pits, reducing the labor intensity of operators and providing more reliable data support for monitoring the solid-state fermentation process and optimizing the fermentation technology, thus powerfully promoting the technological progress and development of the solid-state fermentation industry.

[0049] The scraper 213 is an arc-shaped scraper with an angle between it and the outer wall of the inner sleeve 12. During the scraping process, the arc-shaped scraper naturally guides the mash towards the sampling cylinder 21. Its arc-shaped structure acts like a guide plate, allowing the mash to enter the storage cavity 211 of the sampling cylinder 21 more smoothly under the push of the scraper 213, reducing spillage and loss of mash during sampling and improving sampling efficiency. The size of the angle between the arc-shaped scraper and the outer wall of the inner sleeve 12 affects the force applied by the scraper 213 when scraping the mash. An appropriate angle allows the scraper 213 to apply optimal force to the mash, ensuring smooth scraping without excessive disturbance, thus preserving the original state and properties of the sample and improving sampling accuracy.

[0050] Rotating the outer sleeve 11 allows control over the extension of the scraper 213. Since the scraper 213 is fixed at the bottom of the inner sleeve 12, and the inner sleeve 12 and the outer sleeve 11 are interconnected by a threaded structure, rotating the outer sleeve 11 can change the position of the inner sleeve 12, thereby allowing the scraper 213 to extend from the through slot 212 of the sampling cylinder 21. The operation is simple and intuitive, making it easy for operators to flexibly control the working state of the scraper 213 according to actual sampling needs.

[0051] The scraper 213 is the component directly responsible for collecting samples of the mash. When the scraper 213 extends out of the slot 212, as the inner sleeve 12 descends, the scraper 213 can penetrate deep into the mash to scrape it, efficiently scraping the mash into the storage cavity 211 of the sampling cylinder 21. This avoids the omissions or incompleteness that may occur during manual sampling, greatly improving the efficiency and quality of sampling.

[0052] Reference Figure 1 , Figure 2 and Figure 4 The inner sleeve 12 is equipped with a snap-fit ​​component 121, and the sampling cylinder 21 has a groove. The snap-fit ​​component 121 is rotatably installed in the groove. The snap-fit ​​component 121 on the inner sleeve 12 is the key component for connecting with the sampling cylinder 21. It is rotatably installed in the groove of the sampling cylinder 21, which not only establishes a mechanical connection between the two, but also gives the sampling cylinder 21 the ability to rotate flexibly around the inner sleeve 12. This allows the operator to easily adjust the angle of the sampling cylinder 21 when facing sampling needs at different locations in the fermentation pit, expanding the sampling coverage area and ensuring accurate positioning of the sampling point even in complex fermentation environments.

[0053] The groove and the snap-fit ​​121 of the inner sleeve 12 cooperate with each other, providing the snap-fit ​​121 with rotation space and track, making the rotation operation of the sampling cylinder 21 smoother, while also limiting the snap-fit ​​121 within a certain range of motion, ensuring the stability and controllability of its rotation.

[0054] During the sampling process, the snap-fit ​​121 provides stable support for the sampling cylinder 21. When scraping the lees, it encounters greater resistance. The snap-fit ​​121 fits tightly with the groove to prevent the sampling cylinder 21 from shaking or falling off, thus ensuring the continuity and stability of the sampling work and improving the reliability of the entire sampling device.

[0055] During sampling, the positioning rod 22 is inserted into the mash in the fermentation pit to provide precise positioning for the sampling cylinder 21. The positioning rod 22 allows operators to determine the specific sampling location, ensuring that each sampling is performed at the predetermined position, effectively improving sampling accuracy and repeatability, and providing a reliable data foundation for subsequent analysis of the fermentation process. When the scraper 213 performs its scraping operation, the positioning rod 22 can counteract some of the shaking caused by the scraping force, preventing displacement of the sampling cylinder 21 and ensuring that the scraper 213 can accurately scrape the mash at the target location, thus improving sampling precision and quality.

[0056] The bottom of the positioning rod 22 is provided with a tip 221, which can more accurately penetrate the mash and greatly reduce the resistance when inserting it. The mash usually has a certain degree of compactness, and the design of the tip 221 allows the positioning rod 22 to penetrate the mash layer more easily and quickly reach the predetermined positioning depth, reducing the amount of force required by the operator and improving positioning efficiency.

[0057] One end of the outer sleeve 11 is equipped with a handle 3, and the other end is connected to the inner sleeve 12. The handle 3 provides an easy gripping part for the operator. When rotating the outer sleeve 11 to control the extension of the scraper 213, adjusting the height of the sampling device, etc., the operator can hold the handle 3 to apply force more easily, making the operation process more convenient and reducing the difficulty and complexity of operation.

[0058] The drive assembly 14 includes a rotating shaft 141 and a drive source 142. The drive source 142 is installed outside the outer sleeve 11 and drives the rotating shaft 141. The rotating shaft 141 passes through the outer sleeve 11 and extends into the inner part of the outer sleeve 11. The rotating shaft 141 is coaxially connected to a first bevel gear 143. The first bevel gear 143 meshes with and drives a second bevel gear 144. The second bevel gear 144 is coaxially connected to the threaded rod 13. The drive source 142 serves as the power source for the entire drive assembly 14 and can be an electric motor. The drive source 142 provides power for the rotation of the rotating shaft 141. The rotating shaft 141 stably transmits the rotational power output by the drive source 142 to the first bevel gear 143. The second bevel gear 144 meshes tightly with the first bevel gear 143, receives the power transmitted by the first bevel gear 143, and accurately transmits it to the threaded rod 13 coaxially connected to it.

[0059] When the second bevel gear 144 drives the threaded rod 13 to rotate, since the threaded rod 13 is threadedly connected to the inner sleeve 12, the inner sleeve 12 will move up and down in a straight line along the axis of the threaded rod 13. This change in motion directly controls the up and down movement of the inner sleeve 12 and the scraper 213, realizing the scraping operation of mash at different depths in the fermentation pit.

[0060] A limiting plate 15 is fitted on the threaded rod 13. The limiting plate 15 is located between the second bevel gear 144 and the slider 16. The limiting plate 15 can effectively limit the axial movement range of the inner sleeve 12 on the threaded rod 13, prevent the inner sleeve 12 from rising or falling excessively during the lifting process, avoid the excessive displacement of the inner sleeve 12 affecting the normal working position of the scraper 213, and ensure that the entire sampling device operates within a safe and stable stroke range.

[0061] The inner sleeve 12 has an internal thread that engages with the threaded rod 13. This internal thread, which connects with the threaded rod 13, is a key structural element for enabling the inner sleeve 12 to move vertically. When the threaded rod 13 rotates under the drive of the second bevel gear 144, the inner sleeve 12 moves up and down along the axis of the threaded rod 13 through the interaction of its internal thread and the threaded rod 13. This drives the inner sleeve 12 and related components (such as the scraper 213) to move vertically, completing the sampling operation of mash at different depths. The design of the engagement between the threaded rod 13 and the inner sleeve 12 effectively prevents the inner sleeve 12 from shifting or wobbling during lifting, ensuring that the scraper 213 can always accurately reach the predetermined sampling position, thus improving the accuracy and precision of sampling. In addition, the tightly fitted internal thread and threaded rod 13 also provide a certain degree of self-locking, preventing the inner sleeve 12 from accidentally sliding down due to external forces or its own weight, ensuring the safe operation of the equipment.

[0062] The implementation principle of the solid-state fermentation fixed-point sampling device in this application embodiment is as follows: the drive source 142 drives the rotating shaft 141 to rotate, and the rotating shaft 141 transmits power to the coaxially connected first bevel gear 143. The first bevel gear 143 meshes with the second bevel gear 144, converting the horizontal rotation into the vertical rotation, thereby driving the threaded rod 13 coaxially connected with the second bevel gear 144 to rotate. By controlling the start, stop, forward and reverse rotation and speed parameters of the drive source 142, the rotation speed and direction of the threaded rod 13 can be flexibly adjusted, thereby achieving precise control of subsequent operations. The threaded rod 13 cooperates with the inner sleeve 12 with internal threads. The inner sleeve 12 is fitted with a slider 16, and the inner sleeve 12 and the slider 16 are fixedly connected. When the threaded rod 13 rotates, the inner sleeve 12 moves up and down along the axis of the threaded rod 13 through the interaction between the internal threads and the threaded rod 13. The limiting plate 15, sleeved on the threaded rod 13, is located between the second bevel gear 144 and the slider 16. It effectively limits the axial movement range of the inner sleeve 12 on the threaded rod 13, preventing it from rising or falling excessively and ensuring that the entire device operates within a safe and stable stroke range. Simultaneously, the slider 16 is fixedly connected to the inner sleeve 12, further enhancing the stability of the inner sleeve 12's lifting and lowering, and ensuring the smoothness and accuracy of the lifting process.

[0063] One end of the sampling cylinder 21 is rotatably mounted in a groove on the inner sleeve 12 via a snap-fit ​​connector 121, allowing for flexible angle adjustment. During sampling, the positioning rod 22 is inserted into the fermentation pit's mash, providing precise positioning for the sampling cylinder 21 and ensuring the accuracy of the sampling location, while also enhancing the overall stability of the sampling device. The tip 221 at the bottom of the positioning rod 22 is designed to make it easier to insert into the mash, improving positioning accuracy. When the inner sleeve 12 descends, the scraper 213 fixed to the bottom of the inner sleeve 12 descends accordingly. The scraper 213 is arc-shaped and forms an angle with the outer wall of the inner sleeve 12, allowing it to better conform to the inner wall of the fermentation pit, controlling the scraping depth and force, and efficiently scraping the mash into the storage cavity 211 of the sampling cylinder 21, completing the sampling operation. The operator can also control the rotation of the outer sleeve 11 more effortlessly and precisely by rotating the handle 3 on the outer sleeve 11, utilizing the lever principle, thereby controlling the scraper 213 to extend out of the insertion groove 212, adapting to different sampling scenarios.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
