Description

Technical Field

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

[0002] Currently, the volume of regularly shaped objects is typically measured using geometric dimension calculations. However, for soft, irregularly shaped objects like bread and steamed buns, conventional dimension measurement methods are not only difficult to implement, but also prone to inaccurate results due to deformation caused by compression.

[0003] Therefore, the volume displacement method based on Archimedes' principle is commonly used in this field for measurement. A typical procedure involves placing the object to be measured into a specialized volume measuring device filled with rapeseed, and directly obtaining the object's volume by measuring the volume of the displaced rapeseed. However, this method has significant drawbacks: firstly, rapeseed is easily hygroscopic, deformable, and prone to mold, resulting in poor measurement repeatability; secondly, the specialized volume measuring device is large, bulky, and prone to significant volume measurement errors; furthermore, the entire operation is cumbersome and inefficient.

Detailed Implementation

[0022] 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.

[0023] The following is combined with Figures 1-4 This invention describes a volume measuring instrument.

[0024] In some embodiments, such as Figures 1 to 4 As shown, the volume measuring instrument includes a first sphere 1, a second sphere 2, a connecting shaft 3, and a solid filling medium. A first cavity is formed inside the first sphere 1; a second cavity is formed inside the second sphere 2; the connecting shaft 3 is located between the first sphere 1 and the second sphere 2, and includes a first rotating plate 31 and a second rotating plate 32 that are rotatably connected, with corresponding through holes 311 on the first rotating plate 31 and the second rotating plate 32; the solid filling medium can fill the first cavity and / or the second cavity; when the through hole 311 on the first rotating plate 31 is opposite to the through hole 311 on the second rotating plate 32, the first cavity communicates with the second cavity through the through hole 311; when the through hole 311 on the first rotating plate 31 is misaligned with the through hole 311 on the second rotating plate 32, the first cavity and the second cavity are separated.

[0025] Specifically, the volume measuring instrument mainly includes an upper first sphere 1, a lower second sphere 2, a connecting shaft 3 located between the two spheres, and a solid filling medium.

[0026] The first sphere 1 is typically made of a transparent or translucent, sturdy material to facilitate observation of the flow of the internal medium. The first sphere 1 is designed to be openable. The second sphere 2 is positioned below the first sphere 1. Similar to the first sphere 1, the second sphere 2 also has an openable structure, allowing it to be easily opened to insert or remove irregularly shaped samples such as steamed buns or bread.

[0027] The connecting shaft 3 is installed between the first sphere 1 and the second sphere 2. This connecting shaft 3 is not a solid shaft, but includes a first rotating plate 31 and a second rotating plate 32. These two rotating plates are disc-shaped components, arranged in parallel and capable of relative rotation. Each rotating plate has a through hole 311. By rotating the first rotating plate 31 and the second rotating plate 32, the alignment of the through holes 311 on the two rotating plates can be precisely controlled.

[0028] When the through holes 311 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 311 are staggered, the solid portion of the rotating plate forms a sealed partition, completely isolating the upper and lower cavities.

[0029] During the measurement process, firstly, open the lower second sphere 2, gently place the steamed bun or bread to be tested into its cavity, and then close and seal the second sphere 2. Open the upper first sphere 1, and inject sufficient solid filling medium into its internal cavity until the first cavity is filled.

[0030] Slowly rotate the connecting shaft 3 to the open position (so that the through holes 311 of the two rotating plates are fully aligned). At this time, the medium in the first cavity will flow down naturally through the channel, fall into the second cavity, and gradually fill all the gaps around the steamed bun or bread.

[0031] After the medium stops flowing, the connecting shaft 3 is rotated back to the closed position to re-isolate the two cavities. Then, the first sphere 1 is opened, and all the remaining solid filling medium inside is carefully collected and accurately weighed to obtain the remaining mass m0.

[0032] The mass of the solid filling medium, which equals the volume of the first cavity, is denoted as m1. This mass represents the volume of the first cavity. The mass of the medium flowing into the second cavity is m1 - m0.

[0033] Given that the density of the solid filling medium is ρ, the volume V of the steamed bun or bread can be calculated using the following formula: V = (m1-m0) / ρ.

[0034] The volume measuring instrument provided in this embodiment completely avoids the disadvantages of rapeseed, such as easy moisture absorption, deformation, and mold growth. Through a precisely controllable rotary plate channel switch, it ensures that the medium fills the gap between the measured object and the cavity under its own gravity, effectively solving the problem of inconsistent filling density caused by shaking and vibration in the traditional particle method, and greatly improving the accuracy of the measurement results.

[0035] like Figures 1 to 4 As shown, the first sphere 1 includes a first hemisphere 11 and a second hemisphere 12 that are rotatably openable and closed, and a first cavity is formed when the first hemisphere 11 and the second hemisphere 12 are closed; the second sphere 2 includes a third hemisphere 21 and a fourth hemisphere 22 that are rotatably openable and closed, and a second cavity is formed when the third hemisphere 21 and the fourth hemisphere 22 are closed; the first rotating plate 31 and the second rotating plate 32 are located between the second hemisphere 12 of the first sphere 1 and the fourth hemisphere 22 of the second sphere 2.

[0036] When the first hemisphere 11 and the second hemisphere 12 rotate around the hinge axis to the closed state, they together form a complete and sealed first cavity. The third hemisphere 21 and the fourth hemisphere 22 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 31 and the second rotating plate 32 are connected by a rotating shaft 33.

[0037] When measurement is required, the user can open the first sphere 1 (open the first hemisphere 11) to fill the medium, and open the second sphere 2 (open the third hemisphere 21) to place the sample. After closing, all operations can be controlled by rotating the sphere itself or a special knob to align the through holes 311 of the internal rotating plate, achieving cavity connection and isolation without contacting the internal components. The operation process is intuitive and efficient.

[0038] In some embodiments, such as Figures 1 to 4 As shown, the first rotating plate 31 and / or the second rotating plate 32 are provided with a plurality of through holes 311.

[0039] Multiple through-holes 311 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 311 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 311 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 311 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.

[0040] 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.

[0041] 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.

[0042] In some embodiments, such as Figures 1 to 4 As shown, the first hemisphere 11 and / or the second hemisphere 12 are provided with a first sealing strip 13 arranged in a ring; when the first hemisphere 11 and the second hemisphere 12 are closed, the first sealing strip 13 is sealed between the first hemisphere 11 and the second hemisphere 12.

[0043] Specifically, at the mating edges of the first hemisphere 11 and / or the second hemisphere 12, a first sealing strip 13 is provided, arranged annularly along its opening edge. This first sealing strip 13 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 11 and the second hemisphere 12 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 13 is sealed between the mating planes of the first hemisphere 11 and the second hemisphere 12.

[0044] Similarly, at the mating edges of the third hemisphere 21 and / or the fourth hemisphere 22, a second sealing strip 23 is provided, arranged circumferentially along its opening. This second sealing strip 23 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 21 and the fourth hemisphere 22 are closed, the second sealing strip 23 is sealed between them. During this process, the second sealing strip 23 is pressed between the mating planes of the third hemisphere 21 and the fourth hemisphere 22.

[0045] 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.

[0046] To facilitate the placement of the entire volume measuring instrument, a first mounting base 14 is provided on the first hemisphere 11, and a second mounting base 24 is provided on the third hemisphere 21. Both the first mounting base 14 and the second mounting base 24 adopt a flat plate structure. This flat plate mounting base is usually a rigid plate integrally formed with the hemispherical shell or firmly attached by welding, bolts, or other methods. Its surface is precision machined to ensure stable contact with the placement surface (such as a laboratory table) over a large area and in all directions. The first mounting base 14 is located at the top of the first sphere 1 (on the first hemisphere 11), allowing the instrument to be placed upside down; the second mounting base 24 is located at the bottom of the second sphere 2 (on the third hemisphere 21), allowing the instrument to be placed upright.

[0047] In some embodiments, such as Figures 1 to 4As shown, a first sealing strip 13 on one of the first hemisphere 11 and the second hemisphere 12 forms a first mounting groove arranged in a ring; when the first hemisphere 11 and the second hemisphere 12 are closed, the other of the first hemisphere 11 and the second hemisphere 12 is adapted to be placed in the first mounting groove; a second sealing strip 23 on one of the third hemisphere 21 and the fourth hemisphere 22 forms a second mounting groove arranged in a ring; when the third hemisphere 21 and the fourth hemisphere 22 are closed, the other of the third hemisphere 21 and the fourth hemisphere 22 is adapted to be placed in the second mounting groove.

[0048] Specifically, a first sealing strip 13 is provided at the opening edge of one of the first hemispheres 11 and 12 (e.g., the second hemisphere 12), 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.

[0049] Correspondingly, at the opening edge of the other (i.e., the first hemisphere 11), an annular flange is machined that precisely matches the shape and size of the first mounting groove.

[0050] When the first hemisphere 11 and the second hemisphere 12 rotate relative to each other to the closed position, the annular flange on the edge of the first hemisphere 11 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.

[0051] Similarly, this design is also applied between the third hemisphere 21 and the fourth hemisphere 22. That is, a second mounting groove is formed on the second sealing strip 23 on one of them (e.g., the fourth hemisphere 22), and a corresponding flange is provided on the edge of the other (the third hemisphere 21). When the third hemisphere 21 and the fourth hemisphere 22 are closed, the flange is inserted into the second mounting groove, forming a mating interface consistent with the first sphere 1.

[0052] 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.

[0053] 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 311 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.

[0054] like Figures 1 to 4 As shown, the inner diameter of the first sphere 1 and the second sphere 2 is 120mm-125mm, and the outer diameter of the first sphere 1 and the second sphere 2 is 130mm-132mm. This ensures that each cavity has sufficient volume, and the wall thickness of the spheres is uniformly distributed between 5mm and 6mm.

[0055] 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.
