[0019] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0021] Reference Figure 1 to Figure 6, which is the first embodiment of the present invention, proposes a corn moisture content detector, including: a working box 1, having a first accommodating space 101 and a second accommodating space 102, wherein the first accommodating space 101 has a weighing part; a supporting platform, arranged in the first accommodating space 101; a rotating member 10, rotatably arranged on the supporting platform, wherein the inner wall of the rotating member 10 has a plurality of sorting grooves 301, after the rotating member 10 rotates, the plurality of sorting grooves 301 are respectively used to accommodate the ground corn particles; a drying component 2, arranged in the second accommodating space 102, after the working box 1 is closed, the drying component 2 enters the rotating member 10, and the drying component 2 is used to dry the corn particles.

[0022] In the above scheme, the whole is made of high temperature resistant material and is divided into two layers of space. The upper layer is the first storage space 101, and the lower layer is the second storage space 102. The top of the working box 1 is a flip-top structure, which is convenient for placing and removing samples. The weighing part is located at the bottom of the first storage space 101, and a high-precision electronic scale is used to ensure data accuracy. The support platform is fixed above the weighing part, and a rotating part 10 driven by a motor is installed in the center. Rotating part 10: It has a cylindrical structure and can be rotated by a motor. Several sorting slots 301 are evenly distributed along the circumferential direction of the inner wall of the rotating member 10, and the sorting slots 301 are arranged according to the diameter. Under the rotation of the rotating member 10 and the hot air blowing of the drying component, due to the action of centrifugal force, corn particles of different particle sizes can enter different sorting slots 301, including the following situation: corn particles with smaller particle sizes will enter the sorting slots 301 with larger diameters, but because the subsequent sorting slots 301 will have a vibration effect, most of the corn particles with smaller particle sizes can be re-sorted, and finally most of the corn particles will enter the sorting slots of corresponding sizes, and in the process of re-sorting, the corn particles will also be exposed to the hot air blowing in all directions, providing a drying effect, so it can be used to separate corn particles of different particle sizes and accelerate the drying effect. The drying component 2 is composed of an electric heating wire, a fan, etc., and is installed in the second accommodating space 102. When the door of the working box 1 is closed, the drying component 2 can automatically enter the rotating member 10 to evenly heat the material.

[0023] Operation process: 1. Preparation stage: Zero the device, open the flip-type working box 1, put the corn sample to be tested into the rotating part 10, and measure the weight of the undried corn powder. 2. Start the equipment: Close the flip-type working box 1, ensure good sealing to prevent heat loss, and then the drying component 2 enters the rotating part 10. 3. Sample sorting: Start the motor to drive the rotating part 10 to rotate at high speed. Under the action of centrifugal force, corn powder of different particle sizes falls into the sorting slot 301 of corresponding size. 4. Drying treatment: The drying component 2 is turned on, and hot air is blown into the rotating part 10. The hot air will also be under the action of centrifugal force and cooperate with the rotation action to make all corn particles fully and evenly dried. 5. Weight recording: After the drying is completed, the system automatically stops running and records the final weight. 6. Result calculation: The actual moisture content percentage in the corn sample is calculated based on the difference between the initial weight and the final weight.

[0024] Beneficial effects: 1. Improved measurement accuracy: The design of the sorting slot 301 can effectively separate corn particles of different sizes, avoid over-drying of small particles, and improve the accuracy of moisture measurement. 2. Easy to operate: The flip-top design allows users to quickly place and remove samples, simplifying the operation steps. 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 range of applications: Suitable for moisture content detection of various types of grains, not only limited to corn, but also can be extended to other crops such as wheat and soybeans. 5. Energy saving and environmental protection: The optimized drying process is more efficient, can complete the test in a shorter time, and reduces energy consumption. 6. Simple maintenance: Each component is easy to clean and maintain, extending the service life of the instrument.

[0025] Furthermore, the rotating part 10 includes: a cylinder 3, a plurality of sorting grooves 301 are arranged at intervals on the inner wall of the cylinder 3; a conical cylinder 8, which is detachably arranged at the bottom of the cylinder 3, and has a material receiving port 802 in the middle of the bottom surface of the conical cylinder 8; a material receiving box 9, which is detachably arranged on the outer side of the bottom of the conical cylinder 8, and the material receiving box 9 is used to collect corn particles after the detection is completed.

[0026] In the above scheme, the cylinder 3 is the main component of the rotating member 10, and a plurality of sorting slots 301 are arranged in the cylinder 3. These sorting slots 301 are evenly distributed along the inner wall of the cylinder 3. The sorting slots 301 are used to accommodate corn particles of different particle sizes. When the cylinder 3 rotates, during the drying process, due to multiple re-sorting, larger particles will remain in the larger sorting slots 301, while smaller particles will enter the smaller sorting slots 301 through the action of centrifugal force, ensuring that particles of different sizes can be processed separately during the drying process, thereby reducing the situation of over-drying of small particles and improving the accuracy of measurement. 2 The 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 particles falling from the cylinder 3 after drying. Since the conical cylinder 8 is conical in shape, all corn particles can be guided to be concentrated at the receiving port 802. The detachable feature makes the conical barrel 8 easy to clean and maintain, and it is convenient for users to clean up residues regularly to maintain the cleanliness and work efficiency of the equipment. The position of the receiving port 802 can ensure that all corn grains after sorting can smoothly enter the next collection device. The receiving box 9 is arranged on the outside of the bottom of the conical barrel 8 and is also detachable. The receiving box 9 is mainly used to collect corn grains after testing. After the drying process is completed, all corn grains will fall into the receiving box 9 through the receiving port 802 of the conical barrel 8. The detachable design makes it easy for users to take out and empty the receiving box 9, and it is also conducive to cleaning and disinfecting the receiving box 9. The existence of the receiving box 9 simplifies the sample collection steps and avoids the pollution or loss that may be caused by manual operation.

[0027] It should be noted that, due to multiple re-sorting, corn particles of different particle sizes can enter sorting troughs 301 of different sizes. After drying is completed, if the elastic top plate is not opened, the corn particles in the different sorting troughs 301 can slowly fall to the bottom of the conical cylinder 8. At this time, corn particles of different particle sizes are distributed in a fan shape on the surface of the conical cylinder 8. The operator can open the working box 1 to check the drying degree of different particle sizes. It should also be noted that the corn particles to be checked for drying degree need to be put back into the conical cylinder 8 to ensure later measurements.

[0028] Working process: After drying, the corn particles fall into the receiving box 9 through the receiving port 802 of the conical barrel 8. Open the flip-top work box 1, remove the receiving box 9, pour out and collect the dried corn particles. The conical barrel 8 and the receiving box 9 are both detachable, which is convenient for users to clean and maintain, and prolongs the service life of the equipment. The whole process is highly automated, reducing manual intervention and reducing the difficulty of operation. The detachable receiving box 9 helps to reduce cross contamination between samples and ensures the reliability of the test results.

[0029] Furthermore, the drying assembly 2 includes: a box body 201, which is arranged in the second accommodating space 102, and a groove 202 is provided in the middle of the box body 201, and the diameter of the groove 202 is adapted to the diameter of the cylinder 3. After the working box 1 is closed, the groove 202 is buckled on the cylinder 3, and a ventilation hole 203 is provided in the groove 202; a ventilation column 206, which is arranged in the groove 202, and a plurality of air outlets are provided on the side wall of the ventilation column 206; an electric heating tube 207, which is spiral-shaped and is sleeved on the ventilation column 206. On the outside, the electric heating tube 207 is used to provide heat for drying corn particles; the cylindrical body 204 is arranged in the groove 202, and the cylindrical body 204 and the ventilation column 206 are arranged coaxially; there are a plurality of exhaust ducts 205, and the plurality of exhaust ducts 205 are arranged at intervals on the cylindrical body 204, one end of the exhaust duct 205 is connected to the inside of the cylindrical body 204, and the other end of the exhaust duct 205 is connected to the cylinder 3. After the ventilation column 206 is ventilated, the exhaust duct 205 is used to transport hot air into the cylinder 3.

[0030] In the above scheme, the box body 201 is arranged in the second accommodating space 102 of the working box 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 when the working box 1 is closed, the groove 202 can be tightly buckled on the cylinder 3. The design of the groove 202 enables the drying component 2 to directly dock with the cylinder 3 after the working box 1 is closed, forming a closed drying environment. Ventilation holes 203 are arranged in the groove 202, and these ventilation holes 203 are used to introduce and discharge hot air, ensuring air circulation during the drying process. The ventilation column 206 is arranged in the groove 202, and the side wall of the ventilation column 206 has a plurality of air outlets. The ventilation column 206 is the main channel for hot air, and the hot air is evenly transported 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 the distribution of hot air, thereby ensuring that all corn particles can be fully and evenly dried. The electric heating pipe 207 is spiral-shaped and is sleeved on the outside of the ventilation column 206. The electric heating pipe 207 is the core heating element of the drying component 2, which converts electrical energy into thermal energy to provide the heat required for drying. The spiral design increases the surface area of ​​the electric heating pipe 207, improves the heat transfer efficiency, and enables the hot air to heat up quickly and maintain a stable temperature. The cylindrical body 204 is arranged in the groove 202 and is coaxially arranged with the ventilation column 206. The cylindrical body 204, as a concentrated area of ​​hot air, helps guide the hot air from the ventilation column 206 to the exhaust pipe 205. The coaxial arrangement with the ventilation column 206 helps to maintain the stability of the air flow of the wind column 206, so that the hot air is heated more evenly. There are several exhaust pipes 205, which are arranged on the cylindrical body 204 at intervals. One end of each exhaust pipe 205 is connected to the inside of the cylindrical body 204, and the other end is connected to the cylinder 3. The air pipe 205 is a channel for hot air to enter the cylinder 3 from the cylindrical body 204. By providing a plurality of exhaust pipes 205, it is possible to achieve multi-point air supply, further improving the uniformity of the hot air. The existence of the exhaust pipes 205 allows the hot air to enter the cylinder 3 from different directions, ensuring that the corn particles in each sorting slot 301 can be evenly dried.

[0031] Working process: After the working box 1 is closed, the groove 202 of the drying component 2 is tightly fastened on the cylinder 3 to form a closed drying environment. After the electric heating tube 207 is powered on, it starts to heat and generates high-temperature hot air. The hot air enters the cylindrical body 204 through the air outlet of the ventilation column 206, and is evenly transported to the inside of the cylinder 3 through the exhaust pipe 205. After the hot air enters the cylinder 3 from the exhaust pipe 205, it evenly blows the corn particles in each sorting slot 301 for drying. After the drying is completed, the system automatically stops running, and the user can open the working box 1 and take out the dried sample.

[0032] The combined design of the ventilation column 206, the electric heating pipe 207, the cylindrical barrel 204 and the exhaust pipe 205 achieves uniform distribution of hot air, reducing measurement errors caused by local overheating or unevenness. The spiral design of the electric heating pipe 207 improves the heat transfer efficiency, allowing the hot air to heat up quickly and reducing energy consumption. Easy operation: The entire drying process is highly automated, reducing manual intervention and simplifying the operating steps.

[0033] Furthermore, each exhaust pipe 205 is arranged along the tangent direction of the cylindrical body 204 .

[0034] In the above scheme, each exhaust pipe 205 is arranged along the tangential direction of the cylindrical body 204, which can ensure that the hot air enters the cylinder 3 in a tangential direction, thereby forming a vortex in the cylinder 3. Such a vortex helps the hot air to be more evenly distributed to each sorting slot 301, so that corn particles of different particle sizes can be fully and evenly dried, further improving the drying effect and measurement accuracy. The tangential direction arrangement also reduces the direct impact of the airflow, avoids local overheating, and ensures the stability and consistency of the entire drying process.

[0035] Furthermore, the openings of the plurality of sorting slots 301 decrease in size in sequence along the circumferential direction of the cylinder 3 .

[0036] In the above scheme, the openings of several sorting slots 301 decrease in sequence along the circumferential direction of the cylinder 3, ensuring that corn particles of different particle sizes can be effectively sorted during the rotation process. Specifically, when the cylinder 3 starts to rotate, the larger corn particles will stay in the sorting slots 301 with larger openings due to the effects of gravity and centrifugal force; while the smaller particles will pass through these sorting slots 301 with larger openings and eventually fall into the sorting slots 301 with smaller openings. In this way, as the cylinder 3 continues to rotate, particles of different sizes will be gradually separated and distributed in the corresponding sorting slots 301, thereby achieving effective classification of corn particles. This classification mechanism not only helps to reduce the over-drying of small particles during the drying process, but also improves the accuracy and consistency of moisture measurement.

[0037] Furthermore, the opening width of the sorting groove 301 is smaller than the diameter of the sorting groove 301, and the cylinder 3 has an air inlet 302, and also includes: a plurality of air bags 7, each of which is provided with an air bag 7, and the air bag 7 is connected with the air inlet 302; a plurality of spring clips 6, each of which is provided with a spring clip 6, and the spring clip 6 is arc-shaped, and the protruding side of the spring clip 6 abuts against the air bag 7, and the concave side of the spring clip 6 faces the opening of the sorting groove 301. After the cylinder 3 rotates, the air inlet 302 is intermittently connected with the ventilation hole 203.

[0038] In the above scheme, the opening width of the sorting slot 301 is designed to be smaller than the diameter of the sorting slot 301 to ensure that the corn particles can be effectively sorted and retained in the corresponding sorting slot 301 during the rotation process. The cylinder 3 is provided with air inlet holes 302, which are connected to the airbag 7 in each sorting slot 301. An airbag 7 is arranged in each sorting slot 301, and the air inlet holes 302 can fill the airbag 7 after air is taken in. In addition, an arc-shaped spring sheet 6 is also arranged in each sorting slot 301, and the protruding side of the spring sheet 6 abuts against the airbag 7, while the concave side faces the opening of the sorting slot 301. When the cylinder 3 rotates, the air inlet 302 will be intermittently connected with the ventilation hole 203 on the ventilation column 206. For example, when the ventilation hole 203 is connected with the air inlet 302, the airbag 7 is inflated, and the airbag 7 will lift up the arc-shaped spring piece 6 after being inflated. When the ventilation hole 203 is not connected with the air inlet 302, the arc-shaped spring piece 6 will return to its original shape under the action of centrifugal force. Combined with the high-speed rotation of the cylinder, the arc-shaped spring piece 6 can achieve a vibration effect, so that the corn kernels can achieve a small amplitude jump, and the drying progress can be accelerated. The expansion and contraction of the airbag 7 drives the arc-shaped spring piece 6 to move, so that the hot air can more fully contact the corn kernels, thereby improving the drying efficiency.

[0039] Furthermore, the number of the ventilation holes 203 is less than the number of the air inlet holes 302 , and after the ventilation holes 203 are connected to the air inlet holes 302 , the airbag 7 expands and squeezes the spring 6 .

[0040] In the above scheme, the number of ventilation holes 203 is less than the number of air inlet holes 302, ensuring that when the cylinder 3 rotates, the air bag 7 can expand and squeeze the spring piece 6 after the ventilation holes 203 are connected with the air inlet holes 302. Specifically: air inlet holes 302: arranged on the cylinder 3, with a large number, used to introduce hot air. Ventilation holes 203: arranged in the groove 202 of the drying component 2, with a small number, and connected with the air inlet holes 302. When the cylinder 3 is stationary or not aligned with the ventilation holes 203, the air bag 7 is in a natural state, and the spring piece 6 also remains in the original position, with the slightly protruding side abutting against the air bag 7, and the concave side facing the opening of the sorting tank 301. When the cylinder 3 starts to rotate, the air inlet holes 302 will periodically align with the ventilation holes 203 in the groove 202. Once a certain air inlet hole 302 is aligned with the ventilation hole 203, hot air will enter the air bag 7 through the air inlet hole 302. After the hot air enters the air bag 7, the air bag 7 expands rapidly. The expanded airbag 7 pushes the spring piece 6 to move outward, so that the concave side of the spring piece 6 is closer to the opening of the sorting slot 301. When the spring piece 6 moves outward, it can drive the corn particles to move, and the continuous movement of the arc-shaped spring piece 6 can achieve a vibration effect.

[0041] Furthermore, the material receiving box 9 includes: a filter cartridge 901, which is arranged in the material receiving box 9; an exhaust pipe 902, which is arranged on one side of the material receiving box 9, and the exhaust pipe 902 is externally connected to an exhaust pump; an elastic top plate 903, which is slidably arranged at the material receiving port 802, and the elastic top plate 903 is used to seal the material receiving port 802.

[0042] In the above scheme, the material receiving box 9 includes a filter cartridge 901 disposed inside the box, which is used to filter and collect the dried corn particles; a suction pipe 902 is provided on one side, and the suction pipe 902 is externally connected to a suction pump, which is used to generate negative pressure during the collection process to help suck the corn particles into the material receiving box 9; in addition, an elastic top plate 903 is slidably disposed at the material receiving port 802, and the elastic top plate 903 can block the material receiving port 802 after the collection is completed to prevent the corn particles from scattering during the movement or storage process. This not only ensures the effective collection of corn particles, but also improves the cleanliness and convenience of the entire collection process.

[0043] Furthermore, it also includes: a driver, which is arranged in the first accommodating space 101 and is used to drive the cylinder 3 to rotate.

[0044] In the above scheme, the driver is arranged in the first accommodation space 101, and is used to drive the cylinder 3 to rotate. Specifically, the driver is connected to the cylinder 3 through mechanical connections such as gears, belts, etc. When the driver is started, it drives the cylinder 3 to rotate at a set speed. It ensures that the cylinder 3 can rotate smoothly and evenly, so that corn particles of different particle sizes can be effectively separated in the sorting trough 301. The precise control and stable rotation speed of the driver ensure the efficiency and consistency of the entire sorting and drying process, and improve the accuracy and reliability of moisture detection.

[0045] Furthermore, the cylinder 3 has a first threaded portion 303, the tapered cylinder 8 has a second threaded portion 801, and the first threaded portion 303 and the second threaded portion 801 are threadedly connected.

[0046] In the above scheme, the cylinder 3 has a first threaded portion 303, and the conical cylinder 8 has a second threaded portion 801, and the first threaded portion 303 and the second threaded portion 801 are connected by threads. This allows the cylinder 3 and the conical cylinder 8 to be firmly and conveniently disassembled. Specifically, when the conical cylinder 8 needs to be installed on the cylinder 3, it is only necessary to screw the second threaded portion 801 into the first threaded portion 303 to achieve a tight connection; and when cleaning or maintenance is required, the conical cylinder 8 can be easily disassembled by reverse rotation. This threaded connection not only ensures the stability and sealing of the structure, but also facilitates users to perform regular cleaning and maintenance, thereby improving the ease of use and long-term reliability of the equipment.
