Description

Technical Field

[0001] The utility model relates to the field of grain and oil inspection, in particular to a double-cone bidirectional internal flow mixing device for raw grain samples. Background Art

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

[0003] In the current market, although there are some mixing and quartering devices, most of the designs are mainly for grain powder and cannot be directly applied to raw grain samples. For raw grain samples, the 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 and thus affecting the accuracy of inspection results. At the same time, manual operation is also accompanied by a large labor intensity, reducing the work efficiency.

[0004] With the progress of technology and the increasing requirements for the intelligent and automated levels of equipment in the field of grain and oil inspection, the traditional mixing and quartering methods can no longer meet the needs of modern grain and oil inspection.

[0054] The following further describes in detail the implementation mode 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.

[0055] The present utility model provides a double-cone two-way inward-flow mixing device for raw grain samples, as Figures 1 to 7As shown in the figure, the double-cone two-way internal flow type mixing device for raw grain samples includes a raw grain sample mixing device 2 and a raw grain sample reduction and division 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 is formed with a first cavity for loading raw grain samples, and both ends of the mixing bin 21 are respectively provided with a first material port and a second material port communicating with the first cavity; 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, the second door panel 23 is arranged at the second material port, and the first driving mechanism 24 is used for driving the first door panel 22 to block or expose the first material port and driving 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 reduction and division device 3 includes a material distribution bin 31, a material distribution wheel 32 and a third driving mechanism 33. The material distribution bin 31 is formed with a material cavity and a feed port. The material distribution wheel 32 is rotatably arranged in the material cavity, and the side wall of the material cavity is cooperated to divide the material cavity into at least three sub-material cavities. The material distribution wheel 32 is formed with 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 of the sub-material cavities communicates with two discharge ports 321, another sub-material cavity communicates with two discharge ports, and still another sub-material cavity communicates with five discharge ports 321. The third driving mechanism 33 is in transmission connection with the material distribution wheel 32 and is used for driving the material distribution 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 distribution wheel 32 to rotate, the raw grain samples can enter different sub-material cavities through the discharge ports 321. By setting different numbers of discharge ports 321, the reduction and division of 2:2:5 can be completed.

[0056] 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 removal of 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 precisely 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. One side of the material cavity is provided with a feed port for introducing the raw grain samples to be quartered into the device. The dividing wheel 32 can not only rotate freely, but also its design is ingeniously matched 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 is connected to the feed port of the material cavity. More importantly, a plurality of discharge ports 321 are provided on the dividing wheel 32, and these discharge ports 321 are all connected to the second cavity. When the dividing wheel 32 rotates, the raw grain samples introduced from the feed port will first enter the second cavity, and then enter different sub-material cavities through specific discharge ports 321. This design enables the raw grain samples to be effectively distributed into different sub-material cavities during the rotation of the dividing wheel 32.

[0057] 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.

[0058] The original grain sample after mixing, which is introduced from the feed inlet, will first enter the second cavity. When the material distribution wheel 32 rotates, it will then enter different sub-material cavities through specific discharge ports 321. This design enables the original grain sample to be effectively distributed into different sub-material cavities during the rotation of the material distribution wheel 32. Specifically, in the design of the discharge port 321, one sub-material cavity is connected to two discharge ports 321, another sub-material cavity is connected to two discharge ports 321, and yet another sub-material cavity is connected to five discharge ports 321, such that the ratio of the sample quantity in one sub-material cavity to that in other sub-material cavities reaches 2:2:5. To drive the rotation of the material distribution wheel 32, a third driving mechanism 33 is also provided in the device. The third driving mechanism 33 is in transmission connection with the material distribution wheel 32, and ensures that the material distribution wheel 32 rotates in the material cavity at a predetermined speed and direction by providing stable power. In this way, the original grain sample can be accurately distributed into different sub-material cavities through the discharge ports 321, achieving efficient and accurate reduction and division.

[0059] The double-cone bidirectional inward-flow mixing device for original grain samples provided by the present utility model supports the mixing bin through a support structure, which can ensure that the original grain sample is stirred and mixed in all directions in the first cavity, thereby achieving uniform mixing and avoiding the problem of uneven local mixing that may occur in traditional mixing methods. The first driving mechanism is in transmission connection with the first door panel and the second door panel, 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 original grain sample, the first driving mechanism can quickly open and close the first material port and the second material port, improving the convenience and efficiency of operation. In addition, through the rotation of the material distribution wheel and its cooperation with the side wall of the material cavity in the original grain sample reduction and division device, this device can efficiently distribute the original grain sample into at least three sub-material cavities, where one sub-material cavity is connected to two discharge ports, another sub-material cavity is connected to two discharge ports, and yet another sub-material cavity is connected to five discharge ports, thereby achieving an accurate reduction and division ratio of 2:2:5.

[0060] It should be noted that to meet different usage requirements, the original grain sample mixing device 2 can also be equipped with the following extended functions: For example, a weighing sensor is provided in the mixing bin 21 to monitor the weight change of the original grain sample in the mixing bin 21 in real time, providing data support for the control of the mixing ratio. A temperature sensor and a heater / cooler are provided inside the mixing bin 21 to ensure that the original grain sample maintains a constant temperature during the mixing process. Components such as a cleaning nozzle and a water pump are provided inside the mixing bin 21 to realize the automatic cleaning function of the equipment and reduce the labor intensity of manual cleaning.

[0061] In some embodiments, such as Figures 1 to 5As 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.

[0062] During operation, the first door panel 22 is opened to expose the first material port. The raw grain sample to be mixed is poured into the first cavity of the mixing bin 21 through the first material port. Then the first door panel 22 is closed to ensure the closure of the mixing bin 21. The second drive mechanism 25 is started to drive the mixing bin 21 to start rotating on the support structure. During the rotation of the mixing bin 21, the raw grain samples begin 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 as needed to achieve the best mixing effect. When the predetermined mixing time is reached or the sample is observed to be mixed evenly, the second drive mechanism 25 is stopped to stop the rotation of the mixing bin 21. The mixing uniformity of the sample can be detected through the observation window or the sampler to ensure that the requirements are met. Finally, the second door panel 23 is opened to expose the second material port. Take out the mixed raw grain sample from the second material port. Close the second door panel 23 to prepare for the next mixing operation.

[0063] In some embodiments, Figure 1 As shown, the mixing bin 21 includes: a first hopper 211, a second hopper 212, a third hopper 213 and a fourth hopper 214 which 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 port is provided on the first hopper 211, and a second material port is provided on the fourth hopper 214; a 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.

[0064] In this embodiment, since the mixing bin 21 is divided into a plurality of hoppers, the raw grain samples in each hopper will undergo multiple mixing and exchange during rotation, thereby achieving a more uniform and efficient mixing effect. The segmented design allows the operator to more conveniently observe the mixing conditions in each hopper, thereby making adjustments and controls according to the actual conditions. At the same time, sensors and other devices may also be provided on each hopper to achieve automatic monitoring and control.

[0065] 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 to drive the rotation of the entire mixing bin by driving the rotation of the second hopper 212; or the second driving mechanism 25 can be connected to multiple hoppers to achieve more complex mixing actions and effects.

[0066] In some embodiments, as Figures 1 to 5 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.

[0067] 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 process 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 sample is 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.

[0068] In some embodiments, as Figures 1 to 6As 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, and a sample dividing grid 2153 is formed at the gap between the double cone 2151 and the second hopper 212 and / or the third hopper 213. Openings communicating with the inside of the double cone 2151 are provided on both sides of the sample dividing grid 2153 facing the first hopper 211 and the fourth hopper 214; the other end of the double cone 2151 is located in the third hopper 213 and is provided with a second dispersion port, and a second dispersion port cover plate 2154 is provided at the second dispersion port; when 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; when 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.

[0069] Specifically, when the second hopper 212 rotates 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 in the first hopper 211 begins to flow into the second hopper 212. As the samples continue to 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 inside of the double cone 2151 through the openings of the sample dividing grid 2153, and then are led out to the third hopper 213 through the second dispersion port. These samples will eventually flow into the fourth hopper 214 to complete 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 eventually enter the fourth hopper 214, but their flow path is more direct and does not need to pass through the inside 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.

[0070] 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 samples located in the fourth hopper 214 begin to flow into the third hopper 213. As the samples continue to enter, they will encounter the sample dividing grid 2153. The sample dividing grid 2153 causes 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 mouth of the sample dividing grid 2153, and then are discharged through the first dispersion port to the second hopper 212. These samples will eventually flow into the first hopper 211, completing a transfer 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 eventually enter the first hopper 211.

[0071] 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 hollow sample dividing grid. The design of the multiple sample dividing grids 2153 enables the raw grain samples to be dispersed more times during the flowing process, thereby improving the mixing uniformity and efficiency. This design is particularly useful when highly efficient mixing of raw grain samples of different types or characteristics is required, and can meet the requirements of different processes and products.

[0072] 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 open mouth communicating with the interior of the double cone 2151 on the side facing the first hopper 211, and 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 open mouth communicating with the interior of the double cone 2151 on the side facing the fourth hopper 214.

[0073] When the second hopper 212 rotates to directly above the third hopper 213, the materials on one side fall freely and are evenly dispersed after passing through the double cone 2151, and then enter the first or second material distribution grid. Subsequently, a part of the sample freely falls along the outside of the double cone 2151 through the second material distribution grid, and another part of the sample enters the inside of the double cone 2151 through the first material distribution grid and falls. After the two parts of the sample are mixed, they enter the fourth hopper 214, and through the way of free-falling cone dispersion, 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 fall freely and are evenly dispersed after passing through the double cone 2151, and then enter the second or third material distribution grid. Subsequently, a part of the sample freely falls along the outside of the double cone 2151 through the second material distribution grid, and another part of the sample enters the inside of the double cone 2151 through the third material distribution grid and falls. After the two parts of the sample are mixed, they enter the first hopper 211.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] In addition, the introduction of the first valve 216 also provides convenience for the maintenance and cleaning of the mixing bin 21. When a certain hopper needs to be cleaned or repaired, the corresponding valve can be closed to isolate the hopper to be cleaned or repaired from other hoppers, thereby avoiding unnecessary impact on the entire raw grain sample mixing device 2.

[0078] In another embodiment, as Figure 1 and Figure 2As shown in the figure, 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 solenoid valves or sealing plates driven by racks. The first valve 216 is arranged between the first hopper 211 and the second hopper 212. The first hopper 211 communicates with the second hopper 212 through the first valve 216. The second valve 217 is arranged between the third hopper 213 and the fourth hopper 214. The third hopper 213 communicates 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, so as to achieve more precise mixing control. In addition, this design also helps to prevent the 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, thus ensuring the stability and consistency of the mixing effect.

[0079] 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.

[0080] 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 identified by scanning the code and the sample enters the first hopper 211, the first driving mechanism 24 drives the first door plate 22 to close the first material port.

[0081] Then, the first valve 216 and the second valve 217 are opened. At this time, the raw grain sample located in the first hopper 211 begins to flow into the second hopper 212. As the samples continue to 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 ends of the sample dividing grid 2153, and then are exported to the third hopper 213 through the second dispersion port. These samples will eventually flow into the fourth hopper 214 to complete a transfer 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 eventually 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 way of free-falling cone dispersion, different sample grains in the samples are evenly distributed to achieve the purpose of uniform mixing.

[0082] 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, and the raw grain samples located in the fourth hopper 214 will start to flow into the third hopper 213. As the samples continue to 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 ends of the sample dividing grid 2153, and then are discharged through the first dispersion port to the second hopper 212. These samples will eventually flow into the first hopper 211 to complete a transfer 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 eventually enter the first hopper 211. Finally, after repeating the above operations for the pre-designed number of mixing times, 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.

[0083] In some embodiments, as Figures 1 to 5 shown, 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.

[0084] 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 over-rotating or being damaged.

[0085] In some embodiments, as Figures 1 to 6As shown in the figure, the second driving mechanism 25 includes: a third motor; the rotating end of the third motor is connected to the mixing bin 21 and is used to drive the mixing bin 21 to rotate. The second driving mechanism 25, as the core driving component of the entire raw grain sample mixing device 2, is responsible for driving the mixing bin 21 to perform rotational motion to achieve uniform mixing of the raw grain samples. Its design needs to ensure sufficient driving force, stability, and durability to adapt to 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 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 rotational speed. Insufficient power may result in insufficient driving force, while excessive power may increase energy consumption and costs. The rotational speed range of the third motor should meet the rotational speed requirements of the mixing bin 21. For different raw grain samples and mixing requirements, it may be necessary to adjust the rotational speed to achieve the best mixing effect.

[0086] In this embodiment, as Figure 5 shown, the support structure includes: a first rotating shaft 251, a second rotating shaft 252, a first bracket 253, and a second bracket 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 bracket 253 and is connected to one side of the mixing bin 21, the second rotating shaft 252 is rotatably arranged on the second bracket 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.

[0087] Specifically, when the third motor starts, 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 under the drive of the rotating shaft. During the rotation process, the first bracket 253 and the second bracket 254 provide stable support for the rotating shaft to ensure the smooth and reliable rotational motion of the mixing bin 21.

[0088] 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, and a fourth sub-material cavity. The first sub-material cavity and the second sub-material cavity are communicated with their corresponding two discharge ports 321, and the third sub-material cavity and the fourth sub-material cavity are communicated with their corresponding five discharge ports 321.

[0089] Specifically, among these four sub-material cavities, the design principles of the first sub-material cavity and the second sub-material cavity are similar, and they are both directly connected to their corresponding two specific discharge ports 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 connected to two discharge ports, the amount of samples they receive is relatively small, but it is sufficient to meet specific experimental or production requirements.

[0090] The third sub-material cavity and the fourth sub-material cavity are connected to the corresponding five discharge ports 321. When the material distribution wheel 32 rotates, the third sub-material cavity and the fourth sub-material cavity will simultaneously receive the raw grain samples from the corresponding five discharge ports. Therefore, the amount of samples they receive will be more than that of other sub-material cavities. This design enables the third sub-material cavity and the fourth sub-material cavity to store more quartered raw grain samples.

[0091] Through this design of multiple sub-material cavities, the raw grain sample quartering device 3 can simultaneously achieve quartering in multiple different ratios (achieving a quartering ratio of 2:2:5:5), improving the flexibility and practicality of the equipment. At the same time, since each sub-material cavity is directly connected to its corresponding discharge port, the quartering process is more accurate and reliable, ensuring the accuracy of experimental and production results.

[0092] 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, and a third 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 butt-jointed to form a material cavity, the first housing 311 and the first discharge partition form the first sub-material cavity, the first discharge partition and the second discharge partition form the second sub-material cavity in the material cavity, the second discharge partition and the third discharge partition form the third sub-material cavity in the material cavity, and the third discharge partition and the second housing 312 form the fourth sub-material cavity in the material cavity.

[0093] In this embodiment, the first housing 311 and the second housing 312 are docked with each other, and the two are closely fitted together to jointly form a closed material chamber. This material chamber is the area for storing and preparing the distribution of 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 material chamber for storing the third part of the raw grain samples. Finally, the space between the third discharge partition and the second housing 312 forms a fourth sub-material chamber in the material chamber. This sub-material chamber is used to receive and store the fourth part of the raw grain samples distributed from the material chamber.

[0094] To facilitate the export of the corresponding amount of raw grain samples, as Figures 7 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, and a fourth discharge pipe 37. The first discharge pipe 34 communicates with the first sub-material chamber. The second discharge pipe 35 communicates with the second sub-material chamber. The third discharge pipe 36 communicates with the third sub-material chamber. The fourth discharge pipe 37 communicates with the fourth sub-material chamber.

[0095] In this embodiment, the first discharge pipe 34 communicates with the first sub-material chamber and is used to export the raw grain samples in the first sub-material chamber. The second discharge pipe 35 communicates with the second sub-material chamber and is used to export the raw grain samples in the second sub-material chamber. The third discharge pipe 36 communicates with the third sub-material chamber and is used to export the raw grain samples in the third sub-material chamber. The fourth discharge pipe 37 communicates with the fourth sub-material chamber and is used to export the raw grain samples in the fourth sub-material chamber. The first sub-material chamber and the second sub-material chamber receive the samples from two discharge ports 321, and the third sub-material chamber and the fourth sub-material chamber receive the samples from five discharge ports 321, thereby achieving a reduction ratio of 2:2:5:5.

[0096] 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, and the fourth discharge pipe 37 away from the material chamber extend in different directions.

[0097] This design enables each discharge pipe to independently export the raw grain samples in its corresponding sub-material chamber without interfering with or affecting each other. For example, when it is necessary to export the samples in multiple sub-material chambers simultaneously, the staff can easily operate through different discharge pipes without worrying about sample confusion or cross-contamination.

[0098] In addition, the discharge pipes extending in different directions also facilitate the layout and installation of the equipment. In practical applications, according to 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.

[0099] 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 passed through the connecting seats 313 and an external structure.

[0100] Specifically, the locking shaft 39 is rotatably passed through the connecting seats 313 and an 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.

[0101] When the first housing 311 and the second housing 312 are locked, their connection will become very firm, which can not only prevent the raw grain sample in the material chamber from leaking, but also ensure a stable operating environment for the dividing 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.

[0102] In addition, as Figure 8 and Figure 9 shown, 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 dividing 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 the user 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 chamber of the dividing 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 dividing bin 31. When the raw grain sample in the fifth hopper 314 accumulates to a certain extent, they will naturally flow into the material chamber of the dividing bin through the feed pipe 315, and then be reduced by the dividing 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.

[0103] Among them, a third valve 316 is provided on the feed pipe 315. The precise control function of the third valve 316 enables the user to adjust the flow rate and entry speed of the sample at any time according to needs. Such adjustment is not only beneficial to ensuring the stability and continuity of the riffle process, but also helps to improve the accuracy and consistency of the riffle result. By precisely controlling the opening degree of the third valve 316, the user can ensure that the raw grain sample flows into the splitter bin at an appropriate speed, thus avoiding the accumulation or overflow of the sample in the material chamber and ensuring the smooth progress of the riffle process. Secondly, the introduction of the third valve 316 also enhances the safety of the raw grain sample riffle device 3. During the riffle process, if an abnormal situation occurs or an emergency stop operation is required, the user can quickly close the third valve 316 to cut off the inflow of the sample, thus 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 splitter bin after the equipment stops running, ensuring the smooth progress of the cleaning and maintenance work of the riffle device.

[0104] In some embodiments, such as Figure 10 and Figure 11 shown, a second cavity is formed inside the splitter wheel 32, and a plurality of discharge ports 321 are formed on the axial and / or radial side walls of the splitter wheel 32. The axial discharge ports refer to the discharge ports distributed along the axis direction of the splitter wheel 32, and they are usually located on both sides of the splitter wheel to ensure that when the splitter wheel rotates, the raw grain sample can flow out along the axial direction. The radial discharge ports refer to the discharge ports distributed along the radius direction of the splitter wheel 32, and they are usually evenly distributed on the side wall of the splitter wheel, so that the raw grain sample can flow out along the radial direction when the splitter wheel rotates. This design enables the splitter wheel 32 to precisely control the discharge position and flow rate of the raw grain sample when rotating, thereby realizing the precise riffle of the raw grain sample. At the same time, by adjusting the number, size and distribution position of the discharge ports 321, the riffle effect can be further optimized to meet the requirements of different experiments and productions.

[0105] In this embodiment, as Figure 11 shown, five discharge ports 321 are provided on one end face of the splitter wheel 32 in the axial direction, which communicate with the fourth sub-material chamber. Nine discharge ports 321 are provided in the radial direction of the splitter wheel 32, which communicate with the second sub-material chamber, the third sub-material chamber and the fourth sub-material chamber respectively. Among them, the first sub-material chamber and the second sub-material chamber communicate with their corresponding two discharge ports 321, and the third sub-material chamber communicates with its corresponding five discharge ports 321.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] In some embodiments, Figure 8 and Figure 9As shown in the figure, the third driving mechanism 33 includes: a fourth motor 331 and a speed reducer 332. The rotating shaft of the fourth motor 331 is drivingly connected to the material distributing wheel 32 through the speed reducer 332. The fourth motor 331, as the core component of the entire driving system, is responsible for generating the rotational torque to drive the entire system to work. It can precisely adjust the rotational speed and direction of rotation according to the control instructions, thereby achieving precise control of the material distributing wheel 32. The selection of the fourth motor 331 is usually carried out according to the specific requirements of the sample reduction device. Parameters such as power, torque, and rotational speed all need to be carefully calculated and selected. The speed reducer 332 is installed between the fourth motor 331 and the material distributing wheel 32, and plays the role of reducing the rotational speed and increasing the torque. Since the rotational speed generated by the fourth motor 331 is usually relatively high, while the material distributing wheel 32 requires a relatively low rotational speed and a large torque, it is necessary to carry out the conversion of the transmission ratio through the speed reducer 332. The transmission ratio of the speed reducer 332 can be adjusted according to the actual requirements, thereby achieving precise control of the rotational speed of the material distributing wheel 32. The rotating shaft of the fourth motor 331 is drivingly connected to the material distributing wheel 32 through the speed reducer 332 to form a complete power transmission path. When the fourth motor 331 starts, the rotational torque generated by it is transmitted to the material distributing wheel 32 after being converted by the speed reducer 332, driving it to rotate. During the rotation process, the position of the discharge port 321 on the material distributing wheel 32 changes, thereby realizing the distribution of the raw grain samples.
