Description

Technical Field

[0001] The utility model relates to the field of grain and oil inspection, in particular to a double-cone mirror mixing one-to-five unequal-division material dividing system. Background Art

[0002] In the field of grain and oil quality inspection, sample mixing uniformity and sample reduction accuracy are key links to ensure accurate and reliable inspection results. However, traditional methods of raw grain sample processing, especially the mixing and reduction processes, face a series of challenges.

[0003] Although there are some mixing and reducing equipment on the current market, most of them are designed mainly for grain powder and cannot be directly applied to raw grain samples. For raw grain samples, traditional mixing methods often rely on manual operation, which is not only inefficient, but also easily affected by human factors, resulting in unstable mixing effects, which in turn affects the accuracy of the test results. At the same time, manual operation is also accompanied by greater labor intensity, which reduces work efficiency.

[0004] With the advancement of science and technology and the increasing requirements for intelligent and automated equipment in the field of grain and oil inspection, the traditional mixing and dividing methods can no longer meet the needs of modern grain and oil inspection. Therefore, the development of a dual-conical mirror mixing one-to-five unequal-division dividing system that can efficiently and accurately mix and divide raw grain samples has become an urgent problem to be solved in the field of grain and oil quality inspection.

[0050] The following further describes in detail the implementation manners of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0051] The present utility model provides a double - cone mirror - type mixing and one - to - five unequal - division material distribution system, as Figures 1 to 7As shown in the figure, the double-cone mirror mixing and uneven one-in-five material dividing system includes: a raw grain sample mixing device 2 and a raw grain sample reducing and dividing device 3. The raw grain sample mixing device 2 includes: a mixing bin 21, a first door panel 22, a second door panel 23, a first driving mechanism 24 and a support structure. The mixing bin 21 forms a first cavity for loading raw grain samples. A first material port and a second material port communicating with the first cavity are respectively provided at both ends of the mixing bin 21. The first driving mechanism 24 is in transmission connection with the first door panel 22 and the second door panel 23. The first door panel 22 is arranged at the first material port, and the second door panel 23 is arranged at the second material port. The first driving mechanism 24 is used to drive the first door panel 22 to block or expose the first material port and drive the second door panel 23 to block or expose the second material port. The mixing bin 21 is rotatably arranged on the support structure. The raw grain sample reducing and dividing device 3 includes: a material dividing bin 31, a material dividing wheel 32 and a third driving mechanism 33. The material dividing bin 31 forms a material cavity and a feed port. The material dividing wheel 32 is rotatably arranged in the material cavity and divides the material cavity into at least three sub-material cavities in cooperation with the side wall of the material cavity. The material dividing wheel 32 forms a second cavity and a plurality of discharge ports 321 communicating with the second cavity. Each discharge port 321 communicates with the feed port through the second cavity. One sub-material cavity communicates with one discharge port 321, another sub-material cavity communicates with two discharge ports, and yet another sub-material cavity communicates with five discharge ports 321. The third driving mechanism 33 is in transmission connection with the material dividing wheel 32 and is used to drive the material dividing wheel 32 to rotate in the material cavity so that the raw grain samples introduced from the feed port enter the second cavity and then enter the second cavity. In the case where the third driving mechanism 33 drives the material dividing wheel 32 to rotate, the raw grain samples can enter different sub-material cavities through the discharge ports 321.

[0052] In this embodiment, the mixing bin 21 is the main structure of the device and has a first cavity for loading the raw grain samples. To ensure the convenient loading and unloading of the samples, a first feed port and a second feed port communicating with the first cavity are respectively provided at both ends of the mixing bin 21. The design of these two feed ports makes it very convenient to add and remove the raw grain samples. The first door panel 22 and the second door panel 23 are used to control the opening and closing of the first feed port and the second feed port. The first door panel 22 and the second door panel 23 are driven by a first driving mechanism 24. The first driving mechanism 24 can accurately control the movement of the first door panel 22 and the second door panel 23, so that the first door panel 22 can block or expose the first feed port, while the second door panel 23 can block or expose the second feed port. An inlet is provided on one side of the material cavity for introducing the raw grain samples to be reduced into the device. The dividing wheel 32 can not only rotate freely, but its design also cleverly cooperates with the side wall of the material cavity to divide the material cavity into at least three sub-material cavities. A second cavity is formed inside the dividing wheel 32, and this second cavity communicates with the inlet of the material cavity. More importantly, a plurality of discharge ports 321 are provided on the dividing wheel 32, and these discharge ports 321 all communicate with the second cavity. When the dividing wheel 32 rotates, the raw grain samples introduced from the inlet will first enter the second cavity, and then enter different sub-material cavities through specific discharge ports 321. To drive the rotation of the dividing wheel 32, a third driving mechanism 33 is also equipped in the device. The third driving mechanism 33 is in transmission connection with the dividing wheel 32, and provides stable power to ensure that the dividing wheel 32 rotates in the material cavity at a predetermined speed and direction. In this way, the raw grain samples can be accurately distributed into different sub-material cavities through the discharge ports 321, realizing efficient and accurate reduction.

[0053] During the working process, open the first door panel 22 to expose the first feed port. Pour the raw grain samples to be mixed into the first cavity of the mixing bin 21 through the first feed port. Then close the first door panel 22 to ensure the sealing of the mixing bin 21. Drive the mixing bin 21 to start rotating. During the rotation of the mixing bin 21, the raw grain samples start to collide, rub and mix with each other in the first cavity. The rotation speed and duration of the mixing bin 21 can be adjusted according to needs to achieve the best mixing effect. When the predetermined mixing time is reached or it is observed that the samples are mixed evenly, stop the rotation of the mixing bin 21. The mixing uniformity of the samples can be detected through the observation window or the sampler to ensure that the requirements are met. Finally, open the second door panel 23 (or the first door panel 22) to expose the second feed port (or the first feed port). Take out the mixed raw grain samples from the second feed port. Close the second door panel 23 to prepare for the next mixing operation.

[0054] The mixed raw grain sample introduced from the feed port will first enter the second cavity, and can be effectively distributed to different sub-cavities during the rotation of the dividing wheel 32. Specifically, in the design of the discharge ports 321, one sub-cavity is connected to only one discharge port 321, another sub-cavity is connected to two discharge ports 321, and another sub-cavity is connected to five discharge ports 321, so that the ratio of the sample amount in one sub-cavity to the sample amount in other sub-cavities reaches a ratio of 1:2:5.

[0055] The double-conical mirror mixing one-to-five unequal-division material distribution system provided by the utility model supports the mixing bin through a supporting structure, which can ensure that the raw grain sample is stirred and mixed in all directions in the first cavity, thereby achieving uniform mixing and avoiding the problem of local uneven mixing that may occur in the traditional mixing method. The first driving mechanism is connected to the first door panel and the second door panel in a transmission manner, and can conveniently control the opening and closing of the first door panel and the second door panel. When it is necessary to add or remove the raw grain sample, the first driving mechanism can quickly open and close the first material port and the second material port, thereby improving the convenience and efficiency of operation. In addition, the raw grain sample reduction device can efficiently distribute the raw grain sample to at least three sub-material chambers through the rotation of the distribution wheel and the cooperation with the side wall of the material chamber, wherein one sub-material chamber is connected to one discharge port, another sub-material chamber is connected to two discharge ports, and another sub-material chamber is connected to five discharge ports, thereby achieving an accurate reduction ratio of 1:1:5.

[0056] It should be noted that in order to meet different usage requirements, the raw grain sample mixing device 2 can also be equipped with the following extended functions: for example, a weighing sensor is set in the mixing bin 21 to monitor the weight change of the raw grain sample in the mixing bin 21 in real time, and provide data support for the control of the mixing ratio. A temperature sensor and a heater / refrigerator are set inside the mixing bin 21 to ensure that the raw grain sample maintains a constant temperature during the mixing process. Components such as a cleaning nozzle and a water pump are set inside the mixing bin 21 to realize the automatic cleaning function of the equipment and reduce the labor intensity of manual cleaning.

[0057] In some embodiments, Figures 1 to 5 As shown, the raw grain sample mixing device 2 also includes: a second driving mechanism 25. The second driving mechanism 25 is connected to the mixing bin 21 in a transmission manner, and the second driving mechanism 25 is used to drive the mixing bin 21 to rotate so that the raw grain samples are evenly mixed in the first cavity. The second driving mechanism 25 is connected to the mixing bin 21 in a transmission manner, and its function is to drive the mixing bin 21 to rotate. When the mixing bin 21 rotates, the raw grain samples in the first cavity will be affected by the centrifugal force and collide and rub against each other, thereby achieving a uniform mixing effect. This method of rotational mixing is more efficient than traditional static mixing, and can ensure that the raw grain samples achieve an ideal mixing effect in a short time.

[0058] During the working process, open the first door panel 22 to expose the first material inlet. Pour the original grain samples to be mixed into the first cavity of the mixing bin 21 through the first material inlet. Then close the first door panel 22 to ensure the sealing of the mixing bin 21. Start the second driving mechanism 25 to drive the mixing bin 21 to start rotating on the supporting structure. During the rotation of the mixing bin 21, the original grain samples start to collide, rub against each other and mix within the first cavity. The rotation speed and duration of the mixing bin 21 can be adjusted according to needs to achieve the best mixing effect. When the predetermined mixing time is reached or it is observed that the samples are evenly mixed, stop the second driving mechanism 25 to make the mixing bin 21 stop rotating. The mixing uniformity of the samples can be detected through the observation window or the sampler to ensure that the requirements are met. Finally, open the second door panel 23 to expose the second material outlet. Take out the mixed original grain samples from the second material outlet. Close the second door panel 23 to prepare for the next mixing operation.

[0059] In some embodiments, as Figure 1 shown, the mixing bin 21 includes: a first hopper 211, a second hopper 212, a third hopper 213 and a fourth hopper 214 that are connected in sequence. A first cavity is formed in the first hopper 211, the second hopper 212, the third hopper 213 and the fourth hopper 214. A first material inlet is provided on the first hopper 211, and a second material outlet is provided on the fourth hopper 214; the second driving mechanism 25 is connected to at least one of the first hopper 211, the second hopper 212, the third hopper 213 and the fourth hopper 214.

[0060] In this embodiment, since the mixing bin 21 is divided into multiple hoppers, the original grain samples in each hopper will experience multiple mixings and exchanges during rotation, thus achieving a more uniform and efficient mixing effect. The segmented design enables the operator to more conveniently observe the mixing situation in each hopper, so as to make adjustments and controls according to the actual situation. At the same time, sensors and other devices can also be provided on each hopper to achieve automatic monitoring and control.

[0061] In terms of driving, the second driving mechanism 25 is connected to at least one of the first hopper 211, the second hopper 212, the third hopper 213 and the fourth hopper 214. This connection method can be flexibly adjusted according to specific mixing requirements and equipment design. For example, the second driving mechanism 25 can be connected to the second hopper 212, and the rotation of the second hopper 212 can be driven to drive the rotation of the entire mixing bin; or the second driving mechanism 25 can be connected to multiple hoppers to achieve more complex mixing actions and effects.

[0062] In some embodiments, as Figures 1 to 5As shown, the mixing bin 21 further includes: a dispersion mechanism 215. The dispersion mechanism 215 is disposed in the first cavity corresponding to the second hopper 212 and / or the third hopper 213. The dispersion mechanism 215 is configured to disperse the raw grain sample entering the fourth hopper 214 from the first hopper 211 or the raw grain sample entering the first hopper 211 from the fourth hopper 214 during the rotation of the mixing bin 21.

[0063] Specifically, when the mixing bin 21 starts to rotate, the raw grain sample will flow between the first hopper 211, the second hopper 212, the third hopper 213 and the fourth hopper 214 under the action of gravity and centrifugal force. The dispersion mechanism 215 can further break up and disperse these flowing samples, thereby preventing the samples from forming lumps or agglomerates during the flow and ensuring that the samples can be evenly mixed throughout the mixing bin. The specific design of the dispersion mechanism 215 can be adjusted according to actual needs. For example, structures such as rotating blades, stirring rods or vibrators can be used. These structures can generate appropriate shear forces or impact forces during the rotation of the mixing bin to effectively disperse the samples. By introducing the dispersion mechanism 215, this raw grain sample mixing device 2 can further improve the mixing effect and ensure that the raw grain samples are more evenly and thoroughly mixed in the mixing bin. At the same time, this design also increases the adaptability and flexibility of the equipment and can handle raw grain samples of different types and characteristics.

[0064] In some embodiments, as Figures 1 to 6 shown, the dispersion mechanism 215 includes: a double cone 2151. One end of the double cone 2151 is located in the second hopper 212 and is provided with a first dispersion port. A first dispersion port cover plate 2152 is provided at the first dispersion port. The double cone 2151 forms a sample dividing grid 2153 at the gap between the second hopper 212 and / or the third hopper 213. Both sides of the sample dividing grid 2153 facing the first hopper 211 and the fourth hopper 214 are provided with openings communicating with the inside of the double cone 2151. The other end of the double cone 2151 is located in the third hopper 213 and is provided with a second dispersion port. A second dispersion port cover plate 2154 is provided at the second dispersion port. In the case where the second hopper 212 rotates above the third hopper 213, the first dispersion port cover plate 2152 blocks the first dispersion port, and the second dispersion port cover plate 2154 exposes the second dispersion port. In the case where the third hopper 213 rotates above the second hopper 212, the first dispersion port cover plate 2152 exposes the first dispersion port, and the second dispersion port cover plate 2154 blocks the second dispersion port.

[0065] Specifically, when the second hopper 212 rotates to directly above the third hopper 213, the first dispersion port cover plate 2152 and the second dispersion port cover plate 2154 will automatically adjust the opening and closing of the first dispersion port and the second dispersion port. The first dispersion port cover plate 2152 blocks the first dispersion port, and the second dispersion port cover plate 2154 exposes the second dispersion port. At this time, the raw grain sample located in the first hopper 211 begins to flow into the second hopper 212. As the samples continuously enter, they will encounter the sample dividing grid 2153. The ingenious design of the sample dividing grid 2153 enables the samples to be evenly dispersed during the inflow process. The dispersed samples will experience two main flow paths: a part of the samples directly enter the interior of the double cone 2151 through the open end of the sample dividing grid 2153, and then are discharged to the third hopper 213 through the second dispersion port. These samples will ultimately flow into the fourth hopper 214, completing a circulation cycle. And another part of the samples, after being dispersed by the sample dividing grid 2153, will directly fall into the third hopper 213. This part of the samples will also ultimately enter the fourth hopper 214, but their flow path is more direct and does not need to pass through the interior of the double cone 2151. By means of the cone dispersion through free fall, different sample grains in the samples are evenly distributed, achieving the purpose of uniform mixing.

[0066] Next, when the third hopper 213 rotates to directly above the second hopper 212, the first dispersion port cover plate 2152 and the second dispersion port cover plate 2154 will be adjusted again. The first dispersion port cover plate 2152 exposes the first dispersion port, and the second dispersion port cover plate 2154 blocks the second dispersion port. At this time, the raw grain sample located in the fourth hopper 214 begins to flow into the third hopper 213. As the samples continuously enter, they will encounter the sample dividing grid 2153. The sample dividing grid 2153 enables the samples to be evenly dispersed during the inflow process. The dispersed samples will experience two main flow paths: a part of the samples directly enter the interior of the double cone 2151 through the open end of the sample dividing grid 2153, and then are discharged to the second hopper 212 through the first dispersion port. These samples will ultimately flow into the first hopper 211, completing a circulation cycle. And another part of the samples, after being dispersed by the sample dividing grid 2153, will directly fall into the second hopper 212. This part of the samples will also ultimately enter the first hopper 211.

[0067] It should be noted that generally, there are multiple sample dividing grids 2153. The multiple sample dividing grids 2153 are arranged at intervals in sequence along the circumferential direction of the double cone 2151, and the side walls of adjacent sample dividing grids 2153 form a hollowed-out sample dividing grid. The design of the multiple sample dividing grids 2153 enables the raw grain samples to be dispersed more times during the flow process, thereby improving the uniformity and efficiency of mixing. This design is particularly useful when highly efficient mixing of raw grain samples of different types or characteristics is required, and can meet the needs of different processes and products.

[0068] In a specific embodiment, the double cone 2151 cooperates with the side wall of the hopper to form a first sample dividing grid, a second sample dividing grid, and a third sample dividing grid. The first sample dividing grid is provided with an opening communicating with the inside of the double cone 2151 on the side facing the first hopper 211. The second sample dividing grid is a hollow sample dividing grid. The third sample dividing grid is arranged on the back of the first sample dividing grid and is provided with an opening communicating with the inside of the double cone 2151 on the side facing the fourth hopper 214.

[0069] Thus, when the second hopper 212 rotates to directly above the third hopper 213, the materials on one side freely fall into the double cone 2151 and are evenly dispersed, then enter the first material dividing grid or the second material dividing grid. Subsequently, a part of the sample freely falls along the outside of the double cone 2151 through the second material dividing grid, and another part of the sample enters the inside of the double cone 2151 through the first material dividing grid and falls. The two parts of the sample are mixed and then enter the fourth hopper 214. By the way of freely falling and being dispersed by the cone, different sample grains in the sample are evenly distributed to achieve the purpose of uniform mixing. When the third hopper 213 rotates to directly above the second hopper 212, the materials on the other side freely fall into the double cone 2151 and are evenly dispersed, then enter the second material dividing grid or the third material dividing grid. Subsequently, a part of the sample freely falls along the outside of the double cone 2151 through the second material dividing grid, and another part of the sample enters the inside of the double cone 2151 through the third material dividing grid and falls. The two parts of the sample are mixed and then enter the first hopper 211.

[0070] In some embodiments, as Figure 1 and Figure 2 shown, the mixing bin 21 further includes: a first valve 216. The first valve 216 is arranged between the first hopper 211 and the second hopper 212. The first hopper 211 is communicated with the second hopper 212 through the first valve 216.

[0071] In this embodiment, the main function of the first valve 216 is to control whether the first hopper 211 and the second hopper 212 are communicated, and at the same time control the flow rate and speed of the raw grain sample entering the second hopper 212 from the first hopper 211. By precisely adjusting the opening degree of the first valve 216, the operator can flexibly control the mixing speed and mixing ratio of the raw grain sample according to the actual production requirements.

[0072] This design not only improves the flexibility and adaptability of the mixing bin 21, but also makes the entire mixing process more controllable and stable. When precise control of the mixing effect or special process treatment is required, the role of the first valve 216 is particularly important.

[0073] In addition, the introduction of the first valve 216 also facilitates the maintenance and cleaning of the mixing bin 21. When it is necessary to clean or repair a certain hopper, the corresponding valve can be closed to isolate the hopper to be cleaned or repaired from other hoppers, thus avoiding unnecessary impacts on the entire raw grain sample mixing device 2.

[0074] In another embodiment, as Figure 1 and Figure 2 shown, the mixing bin 21 further includes: a first valve 216 and a second valve 217. The first valve 216 and the second valve 217 can be closed by an electromagnetic valve or a sealing plate driven by a rack. The first valve 216 is disposed between the first hopper 211 and the second hopper 212. The first hopper 211 is communicated with the second hopper 212 through the first valve 216. The second valve 217 is disposed between the third hopper 213 and the fourth hopper 214. The third hopper 213 is communicated with the fourth hopper 214 through the second valve 217. The addition of the first valve 216 and the second valve 217 provides more flexibility and controllability for the mixing of raw grain samples. For example, during the mixing process, the operator can close or open these valves as needed to adjust the communication state between different hoppers, thereby achieving more precise mixing control. In addition, this design also helps to prevent leakage and waste of raw grain samples during the mixing process. When the sample in a certain hopper reaches the preset mixing degree, the operator can close the corresponding valve to prevent the sample from continuing to enter the next hopper, thereby ensuring the stability and consistency of the mixing effect.

[0075] Specifically, when the second hopper 212 rotates to directly above the third hopper 213, the first dispersion port cover plate 2152 and the second dispersion port cover plate 2154 will automatically adjust the opening and closing of the first dispersion port and the second dispersion port. The first dispersion port cover plate 2152 blocks the first dispersion port, and the second dispersion port cover plate 2154 exposes the second dispersion port.

[0076] After receiving the feeding instruction, the first driving mechanism 24 drives the first door plate 22 to quickly open the first material port. After the sample information is recognized by scanning the code, after the sample enters the first hopper 211, the first driving mechanism 24 drives the first door plate 22 to close the first material port.

[0077] Then, open the first valve 216 and the second valve 217. At this time, the raw grain sample in the first hopper 211 starts to flow into the second hopper 212. As the samples continuously enter, they will encounter the sample dividing grid 2153. The ingenious design of the sample dividing grid 2153 enables the samples to be evenly dispersed during the inflow process. The dispersed samples will experience two main flow paths: a part of the samples directly enter the interior of the double cone 2151 through the open end of the sample dividing grid 2153, and then are led out to the third hopper 213 through the second dispersion port. These samples will ultimately flow into the fourth hopper 214, completing a circulation cycle. For the other part of the samples, after being dispersed by the sample dividing grid 2153, they will directly fall into the third hopper 213. This part of the samples will also ultimately enter the fourth hopper 214, but their flow path is more direct and does not need to pass through the interior of the double cone 2151. By the method of cone dispersion through free fall, different sample grains in the samples are evenly distributed to achieve the purpose of uniform mixing.

[0078] Next, close the first valve 216 and the second valve 217, and use the second driving mechanism 25 to control the mixing bin 21 to rotate 180 degrees. When the third hopper 213 rotates to directly above the second hopper 212, the first dispersion port cover plate 2152 and the second dispersion port cover plate 2154 will be adjusted again. The first dispersion port cover plate 2152 exposes the first dispersion port, and the second dispersion port cover plate 2154 blocks the second dispersion port. At this time, open the first valve 216 and the second valve 217. The raw grain sample in the fourth hopper 214 starts to flow into the third hopper 213. As the samples continuously enter, they will encounter the sample dividing grid 2153. The sample dividing grid 2153 enables the samples to be evenly dispersed during the inflow process. The dispersed samples will experience two main flow paths: a part of the samples directly enter the interior of the double cone 2151 through the open end of the sample dividing grid 2153, and then are led out to the second hopper 212 through the first dispersion port. These samples will ultimately flow into the first hopper 211, completing a circulation cycle. For the other part of the samples, after being dispersed by the sample dividing grid 2153, they will directly fall into the second hopper 212. This part of the samples will also ultimately enter the first hopper 211. Finally, repeat the above operations until the pre-designed number of mixing times is reached, then lower the first hopper 211 or the fourth hopper 214, and place the samples into the raw grain sample reduction device to complete the operation.

[0079] In some embodiments, such as Figures 1 to 5As shown in the figure, the first driving mechanism 24 includes: a first motor, a second motor, a first turntable 241 and a second turntable 242; both the first door panel 22 and the second door panel 23 include a plurality of fan-shaped plates. The shape of the fan-shaped plates can be designed according to the shape and size of the material inlet to achieve a better sealing effect. The first motor is drivingly connected to the plurality of fan-shaped plates of the first door panel 22 through the first turntable 241 to block or expose the first material inlet by driving the plurality of fan-shaped plates of the first door panel 22. The second motor is drivingly connected to the plurality of fan-shaped plates of the second door panel 23 through the second turntable 242 to block or expose the second material inlet by driving the plurality of fan-shaped plates of the second door panel 23.

[0080] Specifically, a plurality of first connecting rods are provided on the first turntable 241, and each first connecting rod is connected to a fan-shaped plate on the first door panel 22. When the first turntable 241 rotates, each first connecting rod drives the corresponding fan-shaped plate to move, which can block or expose the first material inlet. Similarly, a plurality of second connecting rods are provided on the second turntable 242, and each second connecting rod is connected to a fan-shaped plate on the second door panel 23. When the second turntable 242 rotates, each second connecting rod drives the corresponding fan-shaped plate to move, which can block or expose the second material inlet. At the same time, limit switches can be provided on the rotation paths of the first turntable 241 and the second turntable 242 to prevent the first turntable 241 and the second turntable 242 from rotating excessively or being damaged.

[0081] In some embodiments, as Figures 1 to 6 shown, the second driving mechanism 25 includes: a third motor; the rotating end of the third motor is connected to the mixing bin 21 for driving the mixing bin 21 to rotate. The second driving mechanism 25 is the core driving component of the entire raw grain sample mixing device 2 and is responsible for driving the mixing bin 21 to perform a rotational motion to achieve uniform mixing of the raw grain samples. Its design needs to ensure sufficient driving force, stability and durability to meet the mixing requirements of different types and quantities of raw grain samples. The third motor usually adopts an AC motor or a DC motor, and the specific type can be selected according to the actual operating environment and control requirements. For example, for scenarios that require precise control of the rotation speed and position, a servo motor or a stepper motor can be selected. The power of the third motor should be determined according to the size, weight of the mixing bin 21 and the required maximum rotation speed. Too small power may result in insufficient driving force, while too large power may increase energy consumption and cost. The rotation speed range of the third motor should meet the rotation speed requirements of the mixing bin 21. For different raw grain samples and mixing requirements, the rotation speed may need to be adjusted to achieve the best mixing effect.

[0082] In this embodiment, as Figure 5As shown in the figure, the support structure includes: a first rotating shaft 251, a second rotating shaft 252, a first support 253, and a second support 254; the first rotating shaft 251 and the second rotating shaft 252 are coaxially arranged, the first rotating shaft 251 is rotatably arranged on the first support 253 and is connected to one side of the mixing bin 21, the second rotating shaft 252 is rotatably arranged on the second support 254 and is connected to the other side of the mixing bin 21, and at least one of the first rotating shaft 251 and the second rotating shaft 252 is in transmission connection with the third motor.

[0083] Specifically, when the third motor is started, its rotating end drives the rotating shaft (the first rotating shaft 251 or the second rotating shaft 252) connected to it to rotate through a transmission device. Since the two rotating shafts are coaxially arranged and are both connected to the mixing bin 21, the mixing bin 21 will also rotate driven by the rotating shafts. During the rotation process, the first support 253 and the second support 254 provide stable support for the rotating shafts, ensuring the smooth and reliable rotation movement of the mixing bin 21.

[0084] In some embodiments, as Figures 7 to 12 shown, the sub-material cavities are respectively a first sub-material cavity, a second sub-material cavity, a third sub-material cavity, a fourth sub-material cavity, and a fifth sub-material cavity. The first sub-material cavity, the second sub-material cavity, and the third sub-material cavity are communicated with their corresponding one discharge port 321, the fourth sub-material cavity is communicated with its corresponding two discharge ports 321, and the fifth sub-material cavity is communicated with its corresponding five discharge ports 321.

[0085] Specifically, among these five sub-material cavities, the design principles of the first sub-material cavity, the second sub-material cavity, and the third sub-material cavity are similar, and they are all directly communicated with their corresponding one specific discharge port 321. When the material distribution wheel 32 rotates in the material cavity, these sub-material cavities will receive the raw grain samples flowing out from the second cavity through their respective discharge ports. Since each sub-material cavity is only connected to one discharge port, the amount of samples they receive is relatively small, but it is sufficient to meet specific experimental or production requirements.

[0086] The fourth sub-material cavity is connected to two discharge ports 321. When the material distribution wheel 32 rotates, the fourth sub-material cavity will receive the raw grain samples from two discharge ports at the same time, so the amount of samples it receives will be more than that of other sub-material cavities. This design enables the fourth sub-material cavity to store more reduced raw grain samples. The fifth sub-material cavity is connected to five discharge ports 321. This means that when the material distribution wheel 32 rotates, the fifth sub-material cavity will receive the raw grain samples from five discharge ports at the same time, so the amount of samples it receives will be much more than that of other sub-material cavities. This design enables the fifth sub-material cavity to store a large amount of reduced raw grain samples to meet the needs of large-scale experiments or production.

[0087] With this design of multiple sub-material chambers, the raw grain sample reduction device 3 can simultaneously achieve reduction at multiple different ratios (realize reduction at a ratio of 1:1:1:2:5), improving the flexibility and practicality of the equipment. At the same time, since each sub-material chamber is directly connected to its corresponding discharge port, the reduction process is more accurate and reliable, ensuring the accuracy of experimental and production results.

[0088] In some embodiments, as Figures 7 to 12 shown, the material distribution bin 31 includes: a first housing 311, a second housing 312, and a first discharge partition, a second discharge partition, a third discharge partition, and a fourth discharge partition that are sequentially arranged at intervals along the circumferential direction of the material distribution wheel 32; the first housing 311 and the second housing 312 are mutually butted to form a material chamber, the first housing 311 and the first discharge partition form a first sub-material chamber, the first discharge partition and the second discharge partition form a second sub-material chamber in the material chamber, the second discharge partition and the third discharge partition form a third sub-material chamber in the material chamber, the third discharge partition and the fourth discharge partition form a fourth sub-material chamber in the material chamber, and the fourth discharge partition and the second housing 312 form a fifth sub-material chamber in the material chamber.

[0089] In this embodiment, the first housing 311 and the second housing 312 are mutually butted, and the two are closely matched to jointly form a closed material chamber. This material chamber is the area for storing and preparing to distribute the raw grain samples. The space between the first housing 311 and the first discharge partition is defined as the first sub-material chamber. This sub-material chamber is used to receive and store the first part of the raw grain samples distributed from the material chamber. Immediately afterwards, the space between the first discharge partition and the second discharge partition forms an independent area in the material chamber, which is the second sub-material chamber. It is also used to receive and store the second part of the raw grain samples distributed from the material chamber. The second discharge partition and the third discharge partition form a third sub-material chamber in the said material chamber for storing the third part of the raw grain samples. Similarly, the space between the third discharge partition and the fourth discharge partition constitutes the fourth sub-material chamber for storing the fourth part of the raw grain samples. Finally, the space between the fourth discharge partition and the second housing 312 forms a fifth sub-material chamber in the material chamber. This sub-material chamber is used to receive and store the fifth part of the raw grain samples distributed from the material chamber.

[0090] For the convenience of discharging the corresponding amount of raw grain samples, as Figures 8 to 12 shown, the raw grain sample reduction device 3 further includes: a first discharge pipe 34, a second discharge pipe 35, a third discharge pipe 36, a fourth discharge pipe 37, and a fifth discharge pipe 38. The first discharge pipe 34 is communicated with the first sub-material chamber. The second discharge pipe 35 is communicated with the second sub-material chamber. The third discharge pipe 36 is communicated with the third sub-material chamber. The fourth discharge pipe 37 is communicated with the fourth sub-material chamber. The fifth discharge pipe 38 is communicated with the fifth sub-material chamber.

[0091] In this embodiment, the first discharge pipe 34 is communicated with the first sub-material cavity and is used to discharge the raw grain sample in the first sub-material cavity. The second discharge pipe 35 is communicated with the second sub-material cavity and is used to discharge the raw grain sample in the second sub-material cavity. The third discharge pipe 36 is communicated with the third sub-material cavity and is used to discharge the raw grain sample in the third sub-material cavity. The fourth discharge pipe 37 is communicated with the fourth sub-material cavity and is used to discharge the raw grain sample in the fourth sub-material cavity, and the fourth sub-material cavity receives the samples from two discharge ports 321. The fifth discharge pipe 38 is communicated with the fifth sub-material cavity. Since the fifth sub-material cavity receives the samples from five discharge ports 321, the fifth discharge pipe 38 is responsible for discharging the relatively large amount of raw grain sample in this sub-material cavity, so as to achieve the reduction ratio of 1:1:1:2:5.

[0092] Optionally, as Figure 8 and Figure 9 shown, the ends of the first discharge pipe 34, the second discharge pipe 35, the third discharge pipe 36, the fourth discharge pipe 37 and the fifth discharge pipe 38 away from the material cavity extend in different directions.

[0093] This design enables each discharge pipe to independently discharge the raw grain sample in its corresponding sub-material cavity without interference or influence on each other. For example, when it is necessary to discharge the samples in multiple sub-material cavities simultaneously, the staff can easily operate through different discharge pipes without worrying about sample confusion or cross-contamination.

[0094] In addition, the discharge pipes extending in different directions also facilitate the layout and installation of the equipment. In practical applications, according to the specific site conditions and operation requirements, the discharge pipes can be flexibly placed in appropriate positions to facilitate the operation and observation of the staff.

[0095] In some embodiments, the raw grain sample reduction device 3 further includes: a locking shaft 39. Connecting seats 313 are provided on the first housing 311 and the second housing 312, and the locking shaft 39 is rotatably inserted through the connecting seats 313 and the external structure.

[0096] Specifically, the locking shaft 39 is rotatably inserted through the connecting seats 313 and the external structure. Such a design allows the user to lock or unlock the first housing 311 and the second housing 312 by operating the locking shaft 39. At one end of the locking shaft 39, a handle convenient for holding is provided, and the user can easily lock or unlock the housing by gently turning the handle.

[0097] When the first housing 311 and the second housing 312 are locked, their connection will become very firm, which can not only prevent the leakage of the raw grain sample in the material cavity, but also ensure a stable operating environment for the material distribution wheel 32 during rotation. And when cleaning, maintenance or component replacement is required, the user only needs to reverse the handle of the locking shaft 39 to easily separate the two housings, providing convenience for maintenance work.

[0098] In addition, as shown in Figure 8 and Figure 9 , the raw grain sample reduction device 3 further includes: a fifth hopper 314 and a feed pipe 315; the fifth hopper 314 is located on one side of the material distribution bin 31, and the fifth hopper 314 is communicated with the feed port through the feed pipe 315. The design of the fifth hopper 314 enables users to conveniently pour the raw grain sample into it, preparing for the subsequent reduction operation. In order to smoothly introduce the raw grain sample in the fifth hopper 314 into the material cavity of the material distribution bin, the device is also equipped with a feed pipe 315. One end of the feed pipe 315 is communicated with the bottom of the fifth hopper 314, and the other end is connected to the feed port of the material distribution bin 31. When the raw grain sample in the fifth hopper 314 accumulates to a certain extent, they will naturally flow into the material cavity of the material distribution bin through the feed pipe 315, and then be reduced by the material distribution wheel 32 according to a predetermined ratio. The design of the fifth hopper 314 and the feed pipe 315 not only simplifies the introduction process of the raw grain sample, improves work efficiency, but also ensures the continuity and stability of the reduction operation.

[0099] Among them, a third valve 316 is provided on the feed pipe 315. The precise control function of the third valve 316 enables users to adjust the flow rate and entry speed of the sample at any time according to needs. This adjustment is not only beneficial to ensuring the stability and continuity of the reduction process, but also helps to improve the accuracy and consistency of the reduction result. By precisely controlling the opening degree of the third valve 316, users can ensure that the raw grain sample flows into the material distribution bin at an appropriate speed, thereby avoiding the accumulation or overflow of the sample in the material cavity and ensuring the smooth progress of the reduction process. Secondly, the introduction of the third valve 316 also enhances the safety of the raw grain sample reduction device 3. During the reduction process, if an abnormal situation occurs or an emergency stop operation is required, users can quickly close the third valve 316 to cut off the inflow of the sample, thereby avoiding possible dangers or losses. In addition, the third valve 316 can also prevent the raw grain sample in the fifth hopper 314 from continuing to flow into the material distribution bin after the equipment stops running, ensuring the smooth progress of the cleaning and maintenance work of the reduction device.

[0100] In some embodiments, as shown in Figure 10 and Figure 11As shown, a second cavity is formed in the dividing wheel 32, and a plurality of discharge ports 321 are formed on the axial and / or radial side walls of the dividing wheel 32. The axial discharge ports refer to the discharge ports distributed along the axial direction of the dividing wheel 32, which are usually located on both sides of the dividing wheel to ensure that the raw grain sample can flow out in the axial direction when the dividing wheel rotates. The radial discharge ports refer to the discharge ports distributed along the radial direction of the dividing wheel, which are usually evenly distributed on the side walls of the dividing wheel, so that the raw grain sample can flow out in the radial direction when the dividing wheel rotates. This design enables the dividing wheel 32 to accurately control the outflow position and flow rate of the raw grain sample when it rotates, thereby realizing accurate reduction of the raw grain sample. At the same time, by adjusting the number, size and distribution position of the discharge ports 321, the reduction effect can be further optimized to meet the needs of different experiments and production.

[0101] In this embodiment, Figure 11 As shown, one axial end face of the material dividing wheel 32 is provided with a discharge port 321, which is connected to the first sub-material cavity. The other end face is provided with five discharge ports 321, which are connected to the fifth sub-material cavity. Four discharge ports 321 are provided in the radial direction of the material dividing wheel 32, which are respectively connected to the second sub-material cavity, the third sub-material cavity, and the fourth sub-material cavity, wherein the second sub-material cavity and the third sub-material cavity are connected to one discharge port 321 corresponding to them, and the fourth sub-material cavity is connected to two discharge ports 321 corresponding to it.

[0102] When considering the actual use requirements of the raw grain sample reduction device, the design of the fifth hopper 314 is also optimized accordingly. In order to enhance the flexibility and practicality of the device, a movable cover plate can be added to the fifth hopper 314. The cover plate is in transmission connection with the second driving mechanism, and can be moved between a first position that blocks the entrance of the fifth hopper 314 and a second position that exposes the entrance of the fifth hopper 314 through the drive of the second driving mechanism.

[0103] When the cover is in the first position, it completely blocks the entrance of the fifth hopper 314, preventing the raw grain sample from overflowing from the fifth hopper or being contaminated by the outside world. This design is particularly useful when there is no need to add samples to the fifth hopper, as it ensures that the inside of the fifth hopper is clean and dry, preventing the sample from getting damp or deteriorating.

[0104] When it is necessary to add a raw grain sample to the fifth hopper, the second drive mechanism drives the cover plate to move from the first position to the second position, exposing the entrance of the fifth hopper 314. At this time, the user can conveniently pour the sample into the fifth hopper and prepare for the reduction operation. After adding the sample, the second drive mechanism drives the cover plate back to the first position again to cover the entrance of the fifth hopper again.

[0105] This movable cover design not only improves the flexibility and practicality of the raw grain sample reduction device, but also enhances the safety and reliability of the equipment. By controlling the opening and closing of the cover, users can more flexibly control the sample addition and reduction process to ensure the accuracy and consistency of the reduction results. At the same time, the shielding function of the cover can also prevent external contamination and accidents, protecting the safety of the equipment and operators.

[0106] In some embodiments, Figure 8 and Figure 9 As shown, the third driving mechanism 33 includes: a fourth motor 331 and a reducer 332. The rotating shaft of the fourth motor 331 is connected to the dividing wheel 32 through the reducer 332. As the core component of the entire drive system, the fourth motor 331 is responsible for generating a rotational torque to drive the entire system to work. It can accurately adjust the speed and direction of rotation according to the control instruction, thereby realizing the precise control of the dividing wheel 32. The selection of the fourth motor 331 is usually carried out according to the specific requirements of the reduction device, such as power, torque, speed and other parameters need to be carefully calculated and selected. The reducer 332 is installed between the fourth motor 331 and the dividing wheel 32, which plays a role in reducing the speed and increasing the torque. Since the speed generated by the fourth motor 331 is usually high, and the speed required by the dividing wheel 32 is relatively low and the torque is large, it is necessary to convert the transmission ratio through the reducer 332. The transmission ratio of the reducer 332 can be adjusted according to actual needs, so as to realize the precise control of the speed of the dividing wheel 32. The rotating shaft of the fourth motor 331 is connected to the material distribution wheel 32 through the reducer 332, forming a complete power transmission path. When the fourth motor 331 is started, the rotation torque generated by it is converted by the reducer 332 and then transmitted to the material distribution wheel 32, driving it to rotate. During the rotation process, the position of the discharge port 321 on the material distribution wheel 32 changes, thereby realizing the distribution of the raw grain sample.
