Description

Technical Field

[0001] This invention relates to the field of detector technology, and more specifically, to a corn moisture content detector. Background Technology

[0002] A corn moisture content detector is an instrument specifically designed to measure the moisture content of corn. This equipment is crucial for the agriculture and food processing industries because moisture content is a key indicator for evaluating corn quality and storage stability. For example, the oven drying method: these instruments evaporate the moisture from the sample by heating it, and then calculate the moisture content based on the change in the sample's mass before and after drying. The oven drying method is relatively accurate because the corn needs to be crushed before testing. Currently, due to the varying sizes of the crushed corn particles, uneven drying of small particles and slow drying speeds often occur, leading to measurement errors. Summary of the Invention

[0003] This invention proposes a corn moisture content detector, which solves the problem in related technologies where the small corn particles are unevenly distributed and the drying speed is slow due to the different sizes of the crushed corn particles, resulting in measurement errors.

[0019] The exhaust pipes are arranged at intervals on the cylindrical body. One end of each exhaust pipe is connected to the interior of the cylindrical body, and the other end is connected to the cylinder. After ventilation by the ventilation column, the exhaust pipes are used to deliver hot air into the cylinder.

[0020] Preferably, each of the exhaust pipes is arranged along the tangential direction of the cylindrical body.

From sample sorting to drying to data recording, the entire process is highly automated, reducing errors caused by human factors. It is applicable to the moisture content detection of various types of grains, not limited to corn, but can also be extended to other crops such as wheat and soybeans. The optimized drying process is more efficient, completing the test in a shorter time and reducing energy consumption. The rational design of each component makes it easy to clean and maintain, extending the instrument's service life. Attached Figure Description

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0047] Reference Figures 1-6The first embodiment of the present invention proposes a corn moisture content detector, comprising: a working box 1 having a first accommodating space 101 and a second accommodating space 102, the first accommodating space 101 having a weighing part; a support platform disposed in the first accommodating space 101; a rotating member 10 rotatably disposed on the support platform, the inner wall of the rotating member 10 having a plurality of sorting grooves 301, the plurality of sorting grooves 301 being used to accommodate ground corn kernels after the rotating member 10 rotates; and a drying component 2 disposed in the second accommodating space 102, the drying component 2 entering the rotating member 10 after the working box 1 is closed, the drying component 2 being used to dry the corn kernels.

[0048] In the above design, the entire structure is made of high-temperature resistant material and consists of two layers. The upper layer is the first accommodating space 101, and the lower layer is the second accommodating space 102. The top of the working box 1 has a flip-top structure for easy sample placement and removal. The weighing unit is located at the bottom of the first accommodating space 101, and a high-precision electronic scale is used to ensure data accuracy. The support platform is fixed above the weighing unit, and a motor-driven rotating component 10 is installed at its center. The rotating component 10 has a cylindrical structure and its rotation can be controlled by a motor. The inner wall of the rotating component 10 is uniformly distributed with several sorting grooves 301 along its circumference. The sorting grooves 301 are arranged according to their diameter. Under the rotation of the rotating component 10 and the blowing of hot air from the drying component, due to the centrifugal force, corn particles of different sizes can enter different sorting grooves 301. This includes the following: smaller corn particles will enter larger diameter sorting grooves 301. However, due to the vibration effect of subsequent sorting grooves 301, most of the smaller corn particles can be re-sorted. Ultimately, the vast majority of corn particles will enter the sorting groove of the corresponding size. Moreover, during the re-sorting process, the corn particles will also be in full contact with the hot air, providing a drying effect. Therefore, it can be used to separate corn particles of different sizes and accelerate the drying process. The drying component 2 consists of heating wires, fans, etc., and is installed in the second receiving space 102. When the door of the working chamber 1 is closed, the drying component 2 can automatically enter the rotating component 10 to uniformly heat the material.

[0049] Operating Procedure: 1. Preparation Stage: Zero the device, open the flip-top working chamber 1, place the corn sample to be tested into the rotating component 10, and measure the weight of the undried corn flour. 2. Start the Equipment: Close the flip-top working chamber 1, ensuring a good seal to prevent heat loss. At this time, the drying component 2 enters the rotating component 10. 3. Sample Sorting: Start the motor to drive the rotating component 10 to rotate at high speed. Under the action of centrifugal force, corn flour of different particle sizes falls into the sorting tank 301 of the corresponding size. 4. Drying Process: Turn on the drying component 2, and hot air is blown into the rotating component 10. The hot air, under the action of centrifugal force, combined with the rotation, ensures that all corn kernels are fully and evenly dried. 5. Weight Recording: After drying is completed, the system automatically stops running and records the final weight. 6. Result Calculation: Calculate the actual moisture content percentage in the corn sample based on the difference between the initial weight and the final weight.

[0050] Beneficial Effects: 1. Improved Measurement Accuracy: The design of the sorting tank 301 effectively separates corn kernels of different sizes, preventing small kernels from being over-dried and improving the accuracy of moisture measurement. 2. Simple Operation: The flip-top design allows users to quickly place and remove samples, simplifying the operation process. 3. High Degree of Automation: From sample sorting to drying to data recording, the entire process is highly automated, reducing errors caused by human factors. 4. Wide Applicability: Suitable for moisture content detection of various types of grains, not limited to corn, but also applicable to other crops such as wheat and soybeans. 5. Energy Saving and Environmental Protection: The optimized drying process is more efficient, completing the test in a shorter time and reducing energy consumption. 6. Simple Maintenance: All components are easy to clean and maintain, extending the instrument's service life.

[0051] Furthermore, the rotating component 10 includes: a cylindrical cylinder 3, with a plurality of sorting slots 301 spaced apart on the inner wall of the cylindrical cylinder 3; a conical cylinder 8, detachably disposed at the bottom of the cylindrical cylinder 3, with a receiving port 802 in the middle of the bottom surface of the conical cylinder 8; and a receiving box 9, detachably disposed on the outer side of the bottom of the conical cylinder 8, which is used to collect corn kernels after the inspection is completed.

[0052] In the above scheme, the cylinder 3 is the main component of the rotating part 10, and several sorting grooves 301 are provided inside the cylinder 3. These sorting grooves 301 are evenly distributed along the inner wall of the cylinder 3. The sorting grooves 301 are used to accommodate corn kernels of different sizes. When the cylinder 3 rotates, during the drying process, due to multiple re-sorting, larger particles will remain in the larger sorting grooves 301, while smaller particles will enter the smaller sorting grooves 301 through centrifugal force. This ensures that particles of different sizes can be separated during the drying process, thereby reducing the over-drying of small particles and improving the accuracy of measurement. A conical cylinder 8 is located at the bottom of the cylinder 3 and is detachable. A receiving port 802 is provided in the middle of the bottom surface of the conical cylinder 8. The conical cylinder 8 collects the corn kernels that fall from the cylinder 3 after drying. Because the conical cylinder 8 is conical in shape, it can guide all the corn kernels to concentrate at the receiving port 802. The detachable design makes the conical cylinder 8 easy to clean and maintain, allowing users to regularly remove residues and maintain the cleanliness and efficiency of the equipment. The location of the receiving port 802 ensures that all sorted corn kernels can smoothly enter the next collection device. The receiving box 9, located on the outer bottom of the conical cylinder 8, is also detachable. The receiving box 9 is mainly used to collect the corn kernels after testing. After the drying process, all corn kernels will fall into the receiving box 9 through the receiving port 802 of the conical cylinder 8. The detachable design allows users to easily remove and empty the receiving box 9, and also facilitates cleaning and disinfection. The presence of the receiving box 9 simplifies the sample collection process and avoids contamination or loss that may occur with manual operation.

[0053] It should be noted that due to multiple re-sorting processes, corn kernels of different sizes can enter sorting tanks 301 of different sizes. After drying, if the elastic top plate is not opened, the corn kernels in the different sorting tanks 301 can slowly fall to the bottom of the conical cylinder 8. At this time, the corn kernels of different sizes are distributed in a fan shape on the surface of the conical cylinder 8. This allows the operator to open the working box 1 to check the drying degree of different kernel sizes. It should also be noted that the corn kernels used to check the drying degree need to be put back into the conical cylinder 8 to ensure subsequent measurements.

[0054] Working Process: After drying, the corn kernels fall into the receiving box 9 through the receiving port 802 of the conical cylinder 8. Open the flip-top working chamber 1, remove the receiving box 9, and pour out and collect the dried corn kernels. Both the conical cylinder 8 and the receiving box 9 are detachable, facilitating cleaning and maintenance and extending the equipment's lifespan. The entire process is highly automated, reducing manual intervention and simplifying operation. The detachable receiving box 9 helps reduce cross-contamination between samples, ensuring the reliability of test results.

[0055] Furthermore, the drying assembly 2 includes: a box body 201, disposed within the second receiving space 102, the box body 201 having a groove 202 in the middle, the diameter of the groove 202 being adapted to the diameter of the cylinder 3, the groove 202 engaging with the cylinder 3 after the working box 1 is closed, and the groove 202 having ventilation holes 203; a ventilation column 206, disposed within the groove 202, the ventilation column 206 having several air outlets on its sidewall; and a spiral-shaped electric heating tube 207, which is sleeved on the ventilation column 206. On the outside, the heating element 207 is used to provide heat for drying corn kernels; the cylindrical body 204 is set in the groove 202, and the cylindrical body 204 is coaxially arranged with the ventilation column 206; there are several exhaust pipes 205, which are spaced apart on the cylindrical body 204. One end of the exhaust pipe 205 is connected to the inside of the cylindrical body 204, and the other end of the exhaust pipe 205 is connected to the cylinder 3. After ventilation by the ventilation column 206, the exhaust pipe 205 is used to deliver hot air into the cylinder 3.

[0056] In the above scheme, the box body 201 is disposed within the second receiving space 102 of the working chamber 1, and has a groove 202 in the middle. The diameter of this groove 202 is adapted to the diameter of the cylinder 3, ensuring that the groove 202 can be tightly fastened to the cylinder 3 when the working chamber 1 is closed. The design of the groove 202 allows the drying component 2 to directly connect with the cylinder 3 after the working chamber 1 is closed, forming a closed drying environment. Ventilation holes 203 are provided in the groove 202, which are used to introduce and exhaust hot air, ensuring air circulation during the drying process. A ventilation column 206 is disposed in the groove 202, and the side wall of the ventilation column 206 has several air outlets. The ventilation column 206 is the main channel for hot air, and the hot air is evenly delivered to each sorting slot 301 in the cylinder 3 through the air outlets on the side wall of the ventilation column 206. The design of the ventilation column 206 helps to improve the uniformity of hot air distribution, thereby ensuring that all corn kernels are fully and evenly dried. The heating element 207 is spiral-shaped and sleeved on the outside of the ventilation column 206. The heating element 207 is the core heating element of the drying assembly 2, converting electrical energy into heat energy to provide the heat required for drying. The spiral design increases the surface area of ​​the heating element 207, improving heat transfer efficiency and allowing the hot air to heat up quickly and maintain a stable temperature. The cylindrical body 204 is located within the groove 202 and is coaxially arranged with the ventilation column 206. The cylindrical body 204 serves as a concentrated area for hot air, helping to guide the hot air from the ventilation column 206 to the exhaust duct 205. Coaxial arrangement with the ventilation column 206 helps maintain the stability of the airflow in the column 206, ensuring more uniform heating of the hot air. Several exhaust ducts 205 are spaced apart on the cylindrical body 204. One end of each exhaust duct 205 connects to the interior of the cylindrical body 204, and the other end connects to the cylinder 3. The duct 205 is the channel through which hot air enters the cylinder 3 from the cylindrical body 204. By setting multiple exhaust pipes 205, multi-point air supply can be achieved, further improving the uniformity of hot air. The presence of exhaust pipes 205 allows hot air to enter the cylinder 3 from different directions, ensuring that the corn kernels in each sorting tank 301 are dried evenly.

[0057] Working Process: After the working chamber 1 is closed, the groove 202 of the drying component 2 tightly engages with the cylinder 3, forming a closed drying environment. The heating element 207 is energized and begins heating, generating high-temperature hot air. The hot air enters the cylindrical body 204 through the outlet of the ventilation column 206 and is evenly delivered into the cylinder 3 through the exhaust pipe 205. After entering the cylinder 3 through the exhaust pipe 205, the hot air evenly blows across the corn kernels in each sorting tank 301, drying them. After drying is complete, the system automatically stops operating, and the user can open the working chamber 1 and remove the dried sample.

[0058] The combined design of the ventilation column 206, electric heating element 207, cylindrical body 204, and exhaust pipe 205 achieves uniform distribution of hot air, reducing measurement errors caused by localized overheating or uneven heating. The spiral design of the electric heating element 207 improves heat transfer efficiency, enabling the hot air to heat up quickly and reducing energy consumption. Operation is simple: the entire drying process is highly automated, reducing manual intervention and simplifying operation steps.

[0059] Furthermore, each exhaust duct 205 is arranged along the tangential direction of the cylindrical body 204.

[0060] In the above scheme, each exhaust pipe 205 is arranged tangentially to the cylindrical body 204, ensuring that hot air enters the cylinder 3 tangentially, thereby forming a vortex within the cylinder 3. This vortex helps the hot air to be distributed more evenly to each sorting tank 301, allowing corn kernels of different sizes to be fully and uniformly dried, further improving the drying effect and measurement accuracy. The tangential arrangement also reduces the direct impact of airflow, avoiding localized overheating and ensuring the stability and consistency of the entire drying process.

[0061] Furthermore, the openings of several sorting slots 301 decrease sequentially along the circumference of the cylinder 3.

[0062] In the above scheme, the openings of several sorting tanks 301 decrease sequentially along the circumference of the cylinder 3, ensuring that corn kernels of different sizes can be effectively sorted during rotation. Specifically, when the cylinder 3 begins to rotate, larger corn kernels, due to gravity and centrifugal force, will remain in the sorting tanks 301 with larger openings; while smaller kernels will pass through these larger opening sorting tanks 301 and eventually fall into the sorting tanks 301 with smaller openings. In this way, as the cylinder 3 continues to rotate, kernels of different sizes will be gradually separated and distributed in the corresponding sorting tanks 301, thereby achieving effective grading of the corn kernels. This grading mechanism not only helps to reduce the over-drying of small kernels during the drying process but also improves the accuracy and consistency of moisture measurement.

[0063] Furthermore, the opening width of the sorting groove 301 is smaller than the diameter of the sorting groove 301. The cylinder 3 has an air inlet 302 and also includes: several airbags 7, one airbag 7 in each sorting groove 301, and the airbag 7 is connected to the air inlet 302; several spring pieces 6, one spring piece 6 in each sorting groove 301, the spring piece 6 is arc-shaped, the protruding side of the spring piece 6 abuts against the airbag 7, and the concave side of the spring piece 6 faces the opening of the sorting groove 301. After the cylinder 3 rotates, the air inlet 302 and the ventilation hole 203 are intermittently connected.

[0064] In the above scheme, the opening width of the sorting trough 301 is designed to be smaller than the diameter of the sorting trough 301 to ensure that corn kernels can be effectively sorted and retained within the corresponding sorting trough 301 during rotation. The cylinder 3 is provided with air inlets 302, which are connected to air bladders 7 within each sorting trough 301. Each sorting trough 301 contains one air bladder 7, which is filled with air after being introduced through the air inlets 302. Furthermore, each sorting trough 301 also contains an arc-shaped spring piece 6, with its protruding side abutting against the air bladder 7, while its concave side faces the opening of the sorting trough 301. When the cylinder 3 rotates, the air inlet 302 intermittently connects with the ventilation hole 203 on the ventilation column 206. For example, when the ventilation hole 203 is connected to the air inlet 302, the air bag 7 inflates, which inflates the arc-shaped spring 6. When the ventilation hole 203 is not connected to the air inlet 302, the arc-shaped spring 6 returns to its original shape under the action of centrifugal force. Combined with the high-speed rotation of the cylinder, the arc-shaped spring 6 vibrates, causing the corn kernels to bounce slightly and accelerating the drying process. The expansion and contraction of the air bag 7 drives the arc-shaped spring 6 to move, allowing the hot air to contact the corn kernels more fully and improving the drying efficiency.

[0065] Furthermore, the number of ventilation holes 203 is less than the number of air inlets 302. After the ventilation holes 203 are connected to the air inlets 302, the airbag 7 expands and squeezes the spring 6.

[0066] In the above scheme, the number of ventilation holes 203 is less than the number of air inlets 302, ensuring that when the cylinder 3 rotates, after the ventilation holes 203 and air inlets 302 are connected, the airbag 7 can expand and compress the spring sheet 6. Specifically: Air inlets 302: are located on the cylinder 3, are numerous, and are used to introduce hot air. Ventilation holes 203: are located in the grooves 202 of the drying assembly 2, are few in number, and are connected to the air inlets 302. When the cylinder 3 is stationary or not aligned with the ventilation holes 203, the airbag 7 is in its natural state, and the spring sheet 6 also remains in its original position, with its slightly protruding side abutting against the airbag 7, while the concave side faces the opening of the sorting groove 301. When the cylinder 3 starts to rotate, the air inlets 302 will periodically align with the ventilation holes 203 in the grooves 202. Once an air inlet 302 is aligned with a ventilation hole 203, hot air will enter the airbag 7 through the air inlet 302. After the hot air enters the airbag 7, the airbag 7 expands rapidly. The inflated air bladder 7 pushes the spring 6 outward, bringing the concave side of the spring 6 closer to the opening of the sorting groove 301. As the spring 6 moves outward, it can move the corn kernels. Through the continuous movement of the arc-shaped spring 6, a vibration effect can be achieved.

[0067] Furthermore, the receiving box 9 includes: a filter cartridge 901, which is disposed inside the receiving box 9; an air extraction pipe 902, which is disposed on one side of the receiving box 9, and an air extraction pump is connected to the outside of the air extraction pipe 902; and an elastic top plate 903, which is slidably disposed at the receiving port 802, and the elastic top plate 903 is used to block the receiving port 802.

[0068] In the above solution, the receiving box 9 includes a filter cartridge 901 installed inside for filtering and collecting dried corn kernels; an exhaust pipe 902 is provided on one side, which is connected to an external air pump to generate negative pressure during the collection process, helping to draw the corn kernels into the receiving box 9; in addition, an elastic top plate 903 is slidably installed at the receiving port 802, which can seal the receiving port 802 after collection to prevent the corn kernels from scattering during movement or storage. This not only ensures the effective collection of corn kernels but also improves the cleanliness and convenience of the entire collection process.

[0069] Furthermore, it also includes: a driver, disposed within the first receiving space 101, the driver being used to drive the cylinder 3 to rotate.

[0070] In the above scheme, the driver is located within the first accommodating space 101 and is used to drive the cylinder 3 to rotate. Specifically, the driver is connected to the cylinder 3 via mechanical connections such as gears or belts. When the driver is activated, it drives the cylinder 3 to rotate at a set speed. This ensures that the cylinder 3 can rotate smoothly and uniformly, thereby effectively separating corn kernels of different sizes in the sorting tank 301. The precise control and stable rotation speed of the driver guarantee the high efficiency and consistency of the entire sorting and drying process, and improve the accuracy and reliability of moisture detection.

[0071] Furthermore, the cylindrical cylinder 3 has a first threaded portion 303, and the tapered cylinder 8 has a second threaded portion 801, with the first threaded portion 303 and the second threaded portion 801 threaded together.

[0072] In the above design, the cylindrical cylinder 3 has a first threaded portion 303, and the tapered cylinder 8 has a second threaded portion 801. The first threaded portion 303 and the second threaded portion 801 are connected by threads. This allows the cylindrical cylinder 3 and the tapered cylinder 8 to be securely and easily assembled and disassembled. Specifically, when the tapered cylinder 8 needs to be installed on the cylindrical cylinder 3, a tight connection can be achieved simply by screwing the second threaded portion 801 into the first threaded portion 303; and when cleaning or maintenance is required, the tapered cylinder 8 can be easily disassembled by rotating it in the opposite direction. This threaded connection not only ensures the stability and sealing of the structure but also facilitates regular cleaning and maintenance by the user, improving the ease of use and long-term reliability of the equipment.

[0073] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
