Description

Technical Field

[0001] This utility model relates to the field of grain testing technology, and in particular to a specific volume scoring system. Background Technology

[0002] Among the various indicators for evaluating the storage quality of wheat, the tasting and scoring method, which involves making steamed buns and conducting sensory evaluation, is a crucial step. In this method, the specific volume of the steamed buns (i.e., the ratio of volume to mass) is an important physical parameter for calculating the final score, and its value directly affects the judgment of wheat quality.

[0003] Currently, the conventional method for determining the volume of steamed buns is the seed substitution method. The procedure is roughly as follows: The steamed and cooled bun is placed in a measuring container of known volume, and then granular materials such as millet or rapeseed are added as a filling medium until the container is full. The volume of the bun is indirectly calculated by subtracting the volume of the filling medium from the total volume of the container. Subsequently, the mass of the bun is manually measured, and its specific volume is calculated. A specific volume score is then derived using a predetermined conversion formula.

[0004] However, current methods have a series of inherent drawbacks in practical applications, limiting the efficiency and accuracy of detection: commonly used measuring containers are mostly large, fixed cylindrical structures, which are inconvenient to move, and the processes of filling, leveling, and emptying particles are cumbersome and labor-intensive. Furthermore, the filling medium used is prone to absorbing moisture, leading to changes in inter-particle friction and volume expansion, and there is a risk of mold growth after long-term use. These factors all introduce significant measurement errors, affecting the accuracy and consistency of the results. From filling and leveling to reading and calculation, the entire process is highly dependent on the operator's experience and skill; human error is difficult to avoid, resulting in not only low efficiency but also a high risk of errors.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] The following is combined Figures 1-7 This invention describes the specific volume scoring system.

[0028] In some embodiments, such as Figures 1 to 6As shown, the specific volume scoring system includes: a volume measuring instrument 1, an electronic balance 2, and a specific volume scoring digital display instrument 3. The volume measuring instrument 1 includes a first sphere 11, a second sphere 12, a connecting shaft 13, and a solid filling medium. A first cavity is formed inside the first sphere 11; a second cavity is formed inside the second sphere 12; the connecting shaft 13 is located between the first sphere 11 and the second sphere 12, and includes a first rotating plate 131 and a second rotating plate 132 rotatably connected, with corresponding through holes 1311 on the first rotating plate 131 and the second rotating plate 132; the solid filling medium can fill the first cavity and / or the second cavity; when the through hole 1311 on the first rotating plate 131 is opposite to the through hole 1311 on the second rotating plate 132, the first cavity communicates with the second cavity through the through hole 1311; when the through hole 1311 on the first rotating plate 131 is misaligned with the through hole 1311 on the second rotating plate 132, the first cavity is separated from the second cavity.

[0029] Specifically, the volume measuring instrument 1 mainly includes an upper first sphere 11, a lower second sphere 12, a connecting shaft 13 located between the two spheres, and a solid filling medium.

[0030] The first sphere 11 is typically made of a transparent or translucent, sturdy material to facilitate observation of the flow of the internal medium. The first sphere 11 is designed to be openable. The second sphere 12 is positioned below the first sphere 11. Similar to the first sphere 11, the second sphere 12 also has an openable structure, allowing it to be easily opened to insert or remove irregularly shaped samples such as steamed buns or bread.

[0031] A connecting shaft 13 is installed between the first sphere 11 and the second sphere 12. This connecting shaft 13 is not a solid shaft, but includes a first rotating plate 131 and a second rotating plate 132. These two rotating plates are disc-shaped components, arranged in parallel, and can rotate relative to each other. Each rotating plate has a through hole 1311. By rotating the first rotating plate 131 and the second rotating plate 132, the alignment of the through holes 1311 on the two rotating plates can be precisely controlled.

[0032] When the through holes 1311 are fully aligned, a through channel is formed, connecting the first cavity and the second cavity, allowing the solid filling medium to flow freely within this channel. When the through holes 1311 are staggered, the solid portion of the rotating plate forms a sealed partition, completely isolating the upper and lower cavities.

[0033] During the actual measurement, the solid filling medium is filled into the second sphere 12. The total mass m0 of the entire volume measuring instrument 1 and the solid filling medium is weighed using an electronic balance 2. The data acquisition button of the specific volume rating display instrument 3 or the data acquisition button of the electronic balance 2 is pressed to collect and transmit the data of the total mass m0.

[0034] Invert the volume measuring instrument 1, rotate the rotating connecting shaft 13 to align the through hole 1311 on the first rotating plate 131 and the second rotating plate 132, allowing the solid filling medium in the second sphere 12 to leak into the first sphere 11, leaving a small portion of the solid filling medium inside the second sphere 12. Then rotate the first rotating plate 131 and the second rotating plate 132 to separate the first cavity from the second cavity.

[0035] Weigh the steamed bun with electronic balance 2 to measure the mass m1. Press the data acquisition button of the specific volume scoring digital display instrument 3 or the data acquisition button of electronic balance 2 to collect and transmit the mass m1 data.

[0036] Open the second sphere 12 and place the steamed bun or bread to be tested into the second sphere 12. Rotate the first rotating plate 131 or the second rotating plate 132 to connect the first cavity and the second cavity, allowing the solid filling medium to leak into the second cavity until the entire second cavity of the second sphere 12 is filled.

[0037] Open the first sphere 11, pour out the solid filling medium inside, and weigh it to obtain its mass m2. Since the volumes of both the first sphere 11 and the second sphere 12 are V, the specific volume λ of the steamed bun or bread can be obtained. .

[0038] Finally, the specific volume scoring digital display instrument 3 generates a specific volume score value based on the measured specific volume.

[0039] For example, the specific volume value can be divided into multiple consecutive intervals, each interval corresponding to a fixed score or grade.

[0040] Specific volume λ ≥ 2.3 mL / g: score 15 points; For every 0.1 decrease in specific volume λ, deduct 1.0 point.

[0041] After the score is generated, the specific volume score display instrument 3 will display all key data and results simultaneously or in pages on its digital display screen, which usually includes: steamed bun quality, steamed bun volume, calculated specific volume value and final specific volume score value.

[0042] The specific volume scoring system provided in this embodiment of the utility model can control the flow of the filling medium by rotating the connecting shaft 13. It is simple and quick to operate, greatly shortens the measurement time of a single sample, reduces the labor intensity and learning threshold of operators, and is very suitable for the scenario of rapid, batch, and paperless testing in quality inspection departments.

[0043] In some embodiments, such as Figure 5As shown, the electronic balance 2 includes: a weighing pan 21, a digital display screen 22, and a mass sensor 23; the mass sensor 23 is used to detect the mass of an object placed on the weighing pan 21 and transmit the mass signal to the digital display screen 22 and / or the specific volume rating digital display instrument 3.

[0044] In this embodiment, the weighing pan 21 is used to directly place the object to be weighed, such as the volume measuring instrument 1 in this system, a steamed bun sample, etc. The mechanical structure (such as a bracket) of the weighing pan 21 is connected to the mass sensor 23 below, ensuring that the weight of the object can be accurately and losslessly transmitted to the sensor.

[0045] When an object is placed on the weighing pan 21, its gravity causes a slight deformation in the elastic body of the sensor. This deformation causes a change in the resistance of the strain gauge attached to the elastic body, thereby generating an electrical signal (i.e., a mass signal) that is proportional to the mass.

[0046] In some embodiments, such as Figure 6 and Figure 7 As shown, the specific volume scoring digital display instrument 3 includes: an instrument housing 31, a touch screen 32 and function buttons 33 disposed on the surface of the instrument housing 31, and a main control circuit board 34 disposed inside the instrument housing 31; the main control circuit board 34 is electrically connected to the mass sensor 23 for receiving mass signals, and the touch screen 32 and function buttons 33 are electrically connected to the main control circuit board 34.

[0047] In this embodiment, the touch display screen 32 is a high-resolution color LCD touch screen. It has both information display and input control functions, and can be used to display mass data from the electronic balance 2, intermediate results during the calculation process, and the final specific volume score in real time.

[0048] In addition to the touchscreen, the casing also features a series of physical or membrane function buttons 33, such as [Data Acquisition], [Calculation], [Zeroing], and [Print]. These buttons provide another quick and precise operating method, especially convenient when operating with gloves or requiring blind operation, complementing the touchscreen. The main control circuit board 34 is electrically connected to the mass sensor 23 of the electronic balance 2 via a data interface, reliably receiving the digital quality signals transmitted from it. The main control circuit board can be a dedicated embedded hardware system built on a microcontroller or microprocessor. After obtaining the specific capacitance value, the main control circuit board immediately runs the built-in scoring model (such as linear mapping, interval comparison, or standard curve fitting) to convert the physical quantity (specific capacitance) into an intuitive quality score value.

[0049] For example, the main control circuit board can be a dedicated embedded hardware system built on a microcontroller or microprocessor. Its core is a high-performance processor (such as an ARM Cortex-M series or Cortex-A series), and it is configured with the necessary memory, clock circuitry, and power management modules. This circuit board connects to other components of the system through integrated communication interfaces, and is responsible for running the device's core firmware, performing all tasks including data acquisition, computation, logic control, and user interaction.

[0050] like Figures 1 to 4 As shown, the first sphere 11 includes: a first hemisphere 111 and a second hemisphere 112 that are rotatably openable and closed, and a first cavity is formed when the first hemisphere 111 and the second hemisphere 112 are closed; the second sphere 12 includes: a third hemisphere 121 and a fourth hemisphere 122 that are rotatably openable and closed, and a second cavity is formed when the third hemisphere 121 and the fourth hemisphere 122 are closed; the first rotating plate 131 and the second rotating plate 132 are located between the second hemisphere 112 of the first sphere 11 and the fourth hemisphere 122 of the second sphere 12.

[0051] When the first hemisphere 111 and the second hemisphere 112 rotate around the hinge axis to the closed state, they together form a complete and sealed first cavity. The third hemisphere 121 and the fourth hemisphere 122 also adopt a rotatable opening and closing design. When they are closed, they form a second cavity for accommodating the sample to be tested (such as steamed buns or bread). The first rotating plate 131 and the second rotating plate 132 are connected by a rotating shaft 133.

[0052] When measurement is required, the user can open the first sphere 11 (open the first hemisphere 111) to fill with the medium, and open the second sphere 12 (open the third hemisphere 121) to place the sample. After closing, all operations can be controlled by rotating the sphere itself or by a special knob to align the through holes 1311 of the internal rotating plate, achieving the connection and isolation of the cavity without contacting the internal components. The operation process is intuitive and efficient.

[0053] In some embodiments, such as Figures 1 to 4 As shown, the first hemisphere 111 and / or the second hemisphere 112 are provided with a first sealing strip 113 arranged in a ring; when the first hemisphere 111 and the second hemisphere 112 are closed, the first sealing strip 113 is sealed between the first hemisphere 111 and the second hemisphere 112.

[0054] Specifically, at the mating edges of the first hemisphere 111 and / or the second hemisphere 112, a first sealing strip 113 is provided, arranged annularly along its opening edge. This first sealing strip 113 is typically made of a material with excellent elasticity and compression resilience (such as silicone, nitrile rubber, or polyurethane). Its cross-sectional shape can be designed as circular (O-ring), rectangular (gasket), or a complex form with a hollow cavity to provide a more effective sealing force under pressure. When the first hemisphere 111 and the second hemisphere 112 rotate about the hinge axis to the closed position, the rigid edges of the two hemispheres gradually approach and eventually press together. During this process, the first sealing strip 113 is sealed between the mating planes of the first hemisphere 111 and the second hemisphere 112.

[0055] Similarly, at the mating edge of the third hemisphere 121 and / or the fourth hemisphere 122, a second sealing strip 123 is provided, arranged circumferentially along its opening. This second sealing strip 123 is typically made of a material with excellent elasticity and compression resilience. Its cross-sectional shape can be designed as circular, rectangular, or a complex form with a hollow cavity to provide a more effective sealing force under pressure. When the third hemisphere 121 and the fourth hemisphere 122 are closed, the second sealing strip 123 is sealed between them. During this process, the second sealing strip 123 is pressed between the mating planes of the third hemisphere 121 and the fourth hemisphere 122.

[0056] This embodiment utilizes edge sealing strips, which not only eliminates minor tolerance gaps that may exist in the shell processing, but also forms a strong sealing barrier, effectively preventing external air, moisture and contaminants from entering the cavity.

[0057] In some embodiments, such as Figures 1 to 4 As shown, a first sealing strip 113 on one of the first hemisphere 111 and the second hemisphere 112 forms a first mounting groove arranged in a ring; when the first hemisphere 111 and the second hemisphere 112 are closed, the other of the first hemisphere 111 and the second hemisphere 112 is adapted to be placed in the first mounting groove; a second sealing strip 123 on one of the third hemisphere 121 and the fourth hemisphere 122 forms a second mounting groove arranged in a ring; when the third hemisphere 121 and the fourth hemisphere 122 are closed, the other of the third hemisphere 121 and the fourth hemisphere 122 is adapted to be placed in the second mounting groove.

[0058] Specifically, a first sealing strip 113 is provided at the opening edge of one of the first hemispheres 111 and 112 (e.g., the second hemisphere 112), the first sealing strip 113 forming a first mounting groove extending circumferentially therein. The cross-section of the mounting groove is typically designed to be "U"-shaped or "L"-shaped, forming a continuous groove with a specific width and depth.

[0059] Correspondingly, at the opening edge of the other (i.e., the first hemisphere 111), an annular flange is machined that precisely matches the shape and size of the first mounting groove.

[0060] When the first hemisphere 111 and the second hemisphere 112 rotate relative to each other to the closed position, the annular flange on the edge of the first hemisphere 111 is guided and precisely embedded into the first mounting groove. This fitting structure achieves effective constraint in three dimensions: radial and tangential misalignment is strictly limited, ensuring perfect alignment of the two hemispheres.

[0061] Similarly, this design is also applied between the third hemisphere 121 and the fourth hemisphere 122. Specifically, a second mounting groove is formed on the second sealing strip 123 of one of them (e.g., the fourth hemisphere 122), and a corresponding flange is provided on the edge of the other (the third hemisphere 121). When the third hemisphere 121 and the fourth hemisphere 122 are closed, the flange engages with the second mounting groove, forming a mating interface consistent with the first sphere 11.

[0062] This "embedded" seal provides a sealing barrier. The embedded edge radially compresses the inner and outer walls of the sealing strip groove, creating a wider sealing contact surface. Compared to simple end-face compression, this three-dimensional extrusion deformation more effectively compensates for tolerances, achieving superior sealing reliability.

[0063] To facilitate the placement of the entire volume measuring instrument 1, a first mounting base 114 is provided on the first hemisphere 111, and a second mounting base 124 is provided on the third hemisphere 121. Both the first mounting base 114 and the second mounting base 124 adopt a flat plate structure. This flat plate structure is usually a rigid plate integrally formed with the hemispherical shell or firmly attached by welding, bolts, or other methods. Its surface is machined to ensure stable contact with the placement surface (such as an experimental table surface) over a large area and in all directions. The first mounting base 114 is located at the top of the first sphere 11 (on the first hemisphere 111), allowing the instrument to be placed upside down; the second mounting base 124 is located at the bottom of the second sphere 12 (on the third hemisphere 121), allowing the instrument to be placed upright.

[0064] In some embodiments, such as Figures 1 to 4 As shown, the first rotating plate 131 and / or the second rotating plate 132 are provided with a plurality of through holes 1311.

[0065] Multiple through-holes 1311 are arranged on a single rotating vane (e.g., distributed in a ring array with a specific radius), breaking the binary limitation of a single through-hole 1311 being "fully open" or "fully closed". By precisely controlling the relative rotation angle of the two rotating vanes, different degrees of overlap between the multiple through-holes 1311 can be achieved. When only a few holes partially overlap, a confined channel is formed, allowing the medium to flow slowly and controllably; when all through-holes 1311 are perfectly aligned, the maximum flow cross-section is formed, enabling rapid passage of the medium. This achieves stepless or stepwise precise adjustment from "micro-flow" to "full-flow", suitable for scenarios requiring observation of the slow filling process of the medium or optimization of flow rates for media of different densities.

[0066] Meanwhile, the through hole 1311 on the first rotating plate 131 and the through hole 1311 on the second rotating plate 132 are of the same shape and size.

[0067] Furthermore, the through holes 1311 on the first rotating plate 131 and the through holes 1311 on the second rotating plate 132 can be designed to be different sizes or shapes (for example, one plate has multiple small round holes, and the other plate has a few larger fan-shaped holes). This method facilitates the quick alignment of small holes and large holes, and facilitates the falling of the solid filling medium.

[0068] In some embodiments, the first sphere 11 and / or the second sphere 12 are provided with a marking line 125. The marking line 125 may be a circular engraving, a protruding ridge, or a linear mark drawn with a durable paint that contrasts sharply with the color of the sphere body. Its design ensures that, during particle filling, the operator can easily and accurately observe whether the liquid level of the particles is flush with the marking line 125.

[0069] For example, in this embodiment, the second sphere 12 is provided with a marking line 125, so that when the solid filling medium in the second sphere 12 is introduced into the first sphere 11, a portion of the solid filling medium can be quantitatively reserved in the second sphere 12, which greatly eliminates random errors caused by differences in judgment between different operators or inconsistencies in operation by the same operator each time, providing a precise benchmark for subsequent calculation of sample volume and improving the accuracy of specific volume measurement results.

[0070] Optionally, the solid filling medium is polypropylene granules. The polypropylene granules are processed into uniformly sized, smooth-surfaced spherical or cylindrical spheres. This regular geometry endows them with excellent flow characteristics, allowing them to flow smoothly and rapidly like a liquid between the spherical cavities and through the through-holes 1311 on the rotating plate, ensuring a rapid and residue-free filling process. Polypropylene is a hydrophobic polymer that absorbs almost no moisture. This ensures that the mass and volume of the granules themselves do not change due to variations in ambient humidity, thus guaranteeing the long-term stability of the "medium density" used as a measurement benchmark and fundamentally eliminating measurement errors introduced by changes in the medium itself.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
