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 material 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 reducing methods can no longer meet the needs of modern grain and oil inspection. Therefore, the development of a dual-conical mirror mixing one-division and five-division system that can efficiently and accurately mix and reduce raw grain samples has become an urgent problem to be solved in the field of grain and oil quality inspection.

[0053] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0055] The utility model provides a double cone mirror mixing one-point five-point material system, such as Figures 1 to 7As shown, the double cone mirror mixing one-division five-division system includes: a raw grain sample mixing device 2 and a raw grain sample reduction 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 supporting structure. The mixing bin 21 is formed with a first cavity for loading raw grain samples, and the two ends of the mixing bin 21 are respectively provided with a first material port and a second material port connected to the first cavity; the first driving mechanism 24 is transmission-connected 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, and the first driving mechanism 24 is used to drive the first door panel 22 to cover or expose the first material port and drive the second door panel 23 to cover or expose the second material port; the mixing bin 21 is rotatably arranged on the supporting structure. The raw grain sample reduction device 3 includes: a material division bin 31, a material division wheel 32 and a third driving mechanism 33. The material division bin 31 is formed with a material cavity and a feed port. The dividing wheel 32 is rotatably arranged in the material cavity, and the material cavity is divided into at least two sub-cavities by the side wall of the material cavity. The dividing wheel 32 is formed with a second cavity and a plurality of discharge ports 321 connected to the second cavity, and each discharge port 321 is connected to the feed port through the second cavity, wherein one sub-cavity is connected to one discharge port 321, and another sub-cavity is connected to six discharge ports 321. The third driving mechanism 33 is transmission-connected to the dividing wheel 32, and is used to drive the dividing wheel 32 to rotate in the material cavity, so that the raw grain sample introduced from the feed port enters the second cavity and then enters the second cavity. When the third driving mechanism 33 drives the dividing wheel 32 to rotate, the raw grain sample can enter different sub-cavities through the discharge ports 321, and a 1:6 reduction can be achieved by setting different numbers of discharge ports 321.

[0056] In this embodiment, the mixing bin 21 is the main structure of the device, and has a first cavity for loading raw grain samples. In order to ensure convenient loading and removal of samples, the two ends of the mixing bin 21 are respectively provided with a first material port and a second material port connected to the first cavity. The design of these two material ports makes it very convenient to add and remove 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 material port and the second material port. The first door panel 22 and the second door panel 23 are driven by the 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 cover or expose the first material port, and the second door panel 23 can cover or expose the second material port. A feed port is provided on one side of the material chamber for introducing the raw grain sample to be divided into the device. The dividing wheel 32 can not only rotate freely, but also its design is cleverly matched with the side wall of the material chamber to divide the material chamber into at least two sub-cavities. A second cavity is formed inside the dividing wheel 32, and the second cavity is connected to the feed port of the cavity. More importantly, the dividing wheel 32 is also provided with a plurality of discharge ports 321, and these discharge ports 321 are all connected to the second cavity. When the dividing wheel 32 rotates, the raw grain sample introduced from the feed port will first enter the second cavity, and then enter different sub-cavities through specific discharge ports 321. This design enables the raw grain sample to be effectively distributed to different sub-cavities during the rotation of the dividing wheel 32.

[0057] 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 mixing bin 21 is driven to start rotating. 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 evenly mixed, the mixing bin 21 stops rotating. The mixing uniformity of the sample can be detected through an observation window or a sampler to ensure that the requirements are met. Finally, the second door panel 23 (or the first door panel 22) is opened to expose the second material port (or the first material port). Take out the mixed raw grain sample from the second material port. Close the second door panel 23 and prepare for the next mixing operation.

[0058] The mixed raw grain sample introduced from the feed port will first enter the second cavity, and then enter different sub-cavities through a specific discharge port 321. This design allows the raw grain sample to be effectively distributed to different sub-cavities during the rotation of the distribution wheel 32. Specifically, in the design of the discharge port 321, one sub-cavity is connected to only one discharge port 321, while the other sub-cavity is connected to six discharge ports 321, so that the ratio of the sample amount in one sub-cavity to the sample amount in another sub-cavity reaches a ratio of 1:6.

[0059] The double-cone mirror mixing one-division-five-division system provided by the utility model can ensure that the raw grain sample is stirred and mixed in all directions in the first cavity by supporting the mixing bin through the supporting structure, so as to achieve uniform mixing and avoid the problem of uneven local 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 into at least two sub-material chambers through the rotation of the material distribution wheel and the cooperation with the side wall of the material chamber, and one of the sub-material chambers is connected to the six discharge ports, thereby achieving an accurate reduction ratio of 1:6. This reduction method is faster and more accurate than the traditional manual reduction method. The device structure is simple and clear, and the reduction process can be completed by driving the rotation of the material distribution wheel through the third driving mechanism, without complicated operation steps and manual intervention, thereby reducing the difficulty of operation and labor cost. Since the dividing wheel is provided with a plurality of discharge ports connected with the second cavity, and each discharge port corresponds precisely to a sub-cavity, it can ensure that the sample quantity ratio in each sub-cavity after reduction is accurate.

[0060] 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.

[0061] In some embodiments, 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 mode 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.

[0066] In some embodiments, Figures 1 to 5 As shown, the mixing bin 21 further includes a dispersing mechanism 215. The dispersing mechanism 215 is disposed in a first cavity corresponding to the second hopper 212 and / or the third hopper 213, and the dispersing mechanism 215 is used 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 agglomerations during the flow process, and ensuring that the samples can be evenly mixed in the entire 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 force or impact force when the mixing bin rotates, and 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, the 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, Figures 1 to 6As shown, the dispersing mechanism 215 comprises: a double cone 2151, one end of the double cone 2151 is located at the second hopper 212 and is provided with a first dispersing port, a first dispersing port cover plate 2152 is provided at the first dispersing port, 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, and both sides of the sample dividing grid 2153 facing the first hopper 211 and the fourth hopper 214 are provided with an opening connected to the inside of the double cone 2151; The other end is located at the third hopper 213 and is provided with a second dispersion port, and a second dispersion port cover 2154 is provided at the second dispersion port; when the second hopper 212 rotates to above the third hopper 213, the first dispersion port cover 2152 blocks the first dispersion port, and the second dispersion port cover 2154 exposes the second dispersion port; when the third hopper 213 rotates to above the second hopper 212, the first dispersion port cover 2152 exposes the first dispersion port, and the second dispersion port cover 2154 blocks the second dispersion port.

[0069] Specifically, when the second hopper 212 rotates to the top of 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 continue to enter, they will encounter the sample grid 2153. The ingenious design of the sample grid 2153 allows 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 enters the interior of the double cone 2151 through the open mouth of the sample grid 2153, and then is led out to the third hopper 213 through the second dispersion port. These samples will eventually flow into the fourth hopper 214, completing a circulation cycle. The other part of the samples, after being dispersed by the sample grid 2153, will directly fall into the third hopper 213. This part of the sample 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. The cone dispersion method through free fall makes the different particles in the sample evenly distributed to achieve the purpose of uniform mixing.

[0070] Next, when the third hopper 213 rotates to the top of 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 covers 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 continue to enter, they will encounter the sample grid 2153. The sample grid 2153 allows 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 enters the interior of the double cone 2151 through the open mouth of the sample grid 2153, and then is led out to the second hopper 212 through the first dispersion port. These samples will eventually flow into the first hopper 211, completing a circulation cycle. Another part of the samples, after being dispersed by the sample 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 there are generally multiple sample grids 2153, and the multiple sample grids 2153 are sequentially spaced along the circumference of the double cone 2151, and the side walls of adjacent sample grids 2153 form hollow sample grids. The design of multiple sample grids 2153 allows the raw grain sample to be dispersed more times during the flow process, thereby improving the uniformity and efficiency of mixing. This design is particularly useful when raw grain samples of different types or characteristics need to be efficiently mixed, and can meet the needs of different processes and products.

[0072] In a specific embodiment, the side wall of the double cone 2151 cooperates with the hopper to form a first sampling grid, a second sampling grid and a third sampling grid, the first sampling grid is provided with an opening connected to the inside of the double cone 2151 on the side facing the first hopper 211, and the second sampling grid is a hollow sampling grid. The third sampling grid is arranged on the back of the first sampling grid, and is provided with an opening connected to the inside of the double cone 2151 on the side facing the fourth hopper 214.

[0073] Thus, when the second hopper 212 rotates to the top of the third hopper 213, the material on one side is evenly dispersed by free falling to the double cone 2151, and then enters the first or second dividing grid, and then a part of the sample freely falls along the outside of the double cone 2151 through the second dividing grid, and the other part of the sample passes through the first dividing grid and enters the inside of the double cone 2151, and the two parts of the sample are mixed and enter the fourth hopper 214, and the cone dispersion method of free falling is used to evenly distribute different particles in the sample to achieve the purpose of uniform mixing. When the third hopper 213 rotates to the top of the second hopper 212, the material on the other side is evenly dispersed by free falling to the double cone 2151, and then enters the second or third dividing grid, and then a part of the sample freely falls along the outside of the double cone 2151 through the second dividing grid, and the other part of the sample passes through the third dividing grid and enters the inside of the double cone 2151, and the two parts of the sample are mixed and enter the first hopper 211.

[0074] In some embodiments, Figure 1 and Figure 2 As shown, the mixing bin 21 further includes a first valve 216. The first valve 216 is disposed between the first hopper 211 and the second hopper 212. The first hopper 211 is connected to 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 connected, and to control the flow rate and speed of the raw grain sample from the first hopper 211 into the second hopper 212. By accurately adjusting the opening of the first valve 216, the operator can flexibly control the mixing speed and mixing ratio of the raw grain sample according to actual production needs.

[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 it is necessary to accurately control the mixing effect or perform special process treatment, the role of the first valve 216 is particularly important.

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

[0078] In another embodiment, if Figure 1 and Figure 2As shown, the mixing bin 21 also includes: a first valve 216 and a second valve 217. The first valve 216 and the second valve 217 can be closed by a solenoid valve or a rack-driven sealing plate. The first valve 216 is arranged between the first hopper 211 and the second hopper 212. The first hopper 211 is connected to 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, and the third hopper 213 is connected to 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 connection state between different hoppers, thereby achieving more refined 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 hopper reaches a preset mixing degree, the operator can prevent the sample from continuing to enter the next hopper by closing the corresponding valve, thereby ensuring the stability and consistency of the mixing effect.

[0079] Specifically, when the second hopper 212 rotates to the top of 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] If a loading instruction is received, the first driving mechanism 24 drives the first door panel 22 to quickly open the first material port. After the sample information is identified by scanning the code, after the sample enters the first hopper 211, the first driving mechanism 24 drives the first door panel 22 to close the first material port.

[0081] Then, the first valve 216 and the second valve 217 are opened, and 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 grid 2153. The ingenious design of the sample grid 2153 allows 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 enters the interior of the double cone 2151 through the opening of the sample grid 2153, and then is led out to the third hopper 213 through the second dispersion port. These samples will eventually flow into the fourth hopper 214, completing a circulation cycle. The other part of the samples, after being dispersed by the sample 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. The cone dispersion method of free fall allows the different particles in the sample to be evenly distributed to achieve the purpose of uniform mixing.

[0082] Next, the first valve 216 and the second valve 217 are closed, and the second driving mechanism 25 is used to control the mixing bin 21 to rotate 180 degrees. When the third hopper 213 rotates to the top of 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 covers the second dispersion port. At this time, the first valve 216 and the second valve 217 are opened, and the raw grain sample located in the fourth hopper 214 begins to flow into the third hopper 213. As the samples continue to enter, they will encounter the sample grid 2153. The sample grid 2153 allows 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 grid 2153, and then be led out to the second hopper 212 through the first dispersion port. These samples will eventually flow into the first hopper 211, completing a circulation cycle. The other part of the sample, after being dispersed by the sample dividing grid 2153, will directly fall into the second hopper 212. This part of the sample will also eventually enter the first hopper 211. Finally, after repeating the above operation to the pre-designed mixing times, the first hopper 211 or the fourth hopper 214 is downward, and the sample is placed in the raw grain sample reduction device to complete the operation.

[0083] In some embodiments, Figures 1 to 5 As shown, the first driving mechanism 24 includes: a first motor, a second motor, a first rotating disk 241 and a second rotating disk 242; the first door panel 22 and the second door panel 23 each include a plurality of fan plates. The shape of the fan plates can be designed according to the shape and size of the material opening to achieve a better sealing effect. The first motor is connected to the plurality of fan plates of the first door panel 22 through the first rotating disk 241 to cover or expose the first material opening by driving the plurality of fan plates of the first door panel 22. The second motor is connected to the plurality of fan plates of the second door panel 23 through the second rotating disk 242 to cover or expose the second material opening by driving the plurality of fan plates of the second door panel 23.

[0084] Specifically, a plurality of first connecting rods are provided on the first rotating disk 241, and each first connecting rod is connected to a fan plate on the first door panel 22. When the first rotating disk 241 rotates, each first connecting rod drives the corresponding fan plate to move, so as to cover or expose the first material opening. Similarly, a plurality of second connecting rods are provided on the second rotating disk 242, and each second connecting rod is connected to a fan plate on the second door panel 23. When the second rotating disk 242 rotates, each second connecting rod drives the corresponding fan plate to move, so as to cover or expose the second material opening. At the same time, a limit switch can be set on the rotation path of the first rotating disk 241 and the second rotating disk 242 to prevent the first rotating disk 241 and the second rotating disk 242 from excessive rotation or damage.

[0085] In some embodiments, Figures 1 to 6As shown, 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 is the core driving component of the entire raw grain sample mixing device 2, and is responsible for driving the mixing bin 21 to rotate 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 raw grain samples of different types and quantities. 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 where precise control of speed and position is required, a servo motor or a stepper motor can be selected. The power of the third motor should be determined according to the size, weight and required maximum speed of the mixing bin 21. Too little power may lead to insufficient driving force, while too much power may increase energy consumption and cost. The 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 speed may need to be adjusted to achieve the best mixing effect.

[0086] In this embodiment, Figure 5 As shown, the supporting 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 connected to one side of the mixing bin 21, the second rotating shaft 252 is rotatably arranged on the second bracket 254 and 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 connected to the third motor.

[0087] 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 thereto to rotate through the 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, ensuring that the rotation movement of the mixing bin 21 is smooth and reliable.

[0088] In some embodiments, Figures 7 to 12 As shown, the sub-material chambers are respectively the first sub-material chamber, the second sub-material chamber, the third sub-material chamber, the fourth sub-material chamber and the fifth sub-material chamber. The first sub-material chamber, the second sub-material chamber, the third sub-material chamber and the fourth sub-material chamber are all connected to a corresponding discharge port 321, and the fifth sub-material chamber is connected to six corresponding discharge ports 321.

[0089] Specifically, among the five sub-cavities, the design principles of the first sub-cavity, the second sub-cavity, the third sub-cavity and the fourth sub-cavity are similar, and they are all directly connected to a corresponding specific discharge port 321. When the dividing wheel 32 rotates in the cavity, these sub-cavities receive the raw grain samples flowing out of the second cavity through their respective discharge ports. Since each sub-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 needs.

[0090] The design of the fifth sub-material chamber is different. It is connected to the six discharge ports 321. This means that when the dividing wheel 32 rotates, the fifth sub-material chamber will receive raw grain samples from the six discharge ports at the same time, so the amount of samples it receives will be much larger than that of other sub-material chambers. This design enables the fifth sub-material chamber to store a large number of reduced raw grain samples to meet the needs of large-scale experiments or production.

[0091] Through the design of multiple sub-cavities, the raw grain sample reduction device 3 can simultaneously achieve multiple reductions of different ratios (achieving a reduction ratio of 1:1:1:1:6), thereby improving the flexibility and practicality of the device. At the same time, since each sub-cavity is directly connected to its corresponding discharge port, the reduction process is more precise and reliable, thereby ensuring the accuracy of the experimental and production results.

[0092] In some embodiments, Figures 7 to 12 As shown, the material distribution bin 31 includes: a first shell 311, a second shell 312, and a first discharge baffle, a second discharge baffle, a third discharge baffle and a fourth discharge baffle which are arranged in sequence along the circumference of the material distribution wheel 32; the first shell 311 and the second shell 312 are connected to each other to form a material cavity, the first shell 311 and the first discharge baffle form a first sub-material cavity, the first discharge baffle and the second discharge baffle form a second sub-material cavity in the material cavity, the second discharge baffle and the third discharge baffle form a third sub-material cavity in the material cavity, the third discharge baffle and the fourth discharge baffle form a fourth sub-material cavity in the material cavity, and the fourth discharge baffle and the second shell 312 form a fifth sub-material cavity in the material cavity.

[0093] In this embodiment, the first shell 311 and the second shell 312 are docked with each other, and the two are closely matched to form a closed material chamber. This material chamber is an area for storing and preparing to distribute raw grain samples. The space between the first shell 311 and the first discharging 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 sample distributed from the material chamber. Next, the space between the first discharging partition and the second discharging 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 sample distributed from the material chamber. The second discharging partition and the third discharging partition form a third sub-material chamber in the material chamber for storing the third part of the raw grain sample. Similarly, the space between the third discharging partition and the fourth discharging partition constitutes a fourth sub-material chamber for storing the fourth part of the raw grain sample. Finally, the space between the fourth discharging partition and the second shell 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 sample distributed from the material chamber.

[0094] In order to facilitate the export of the corresponding amount of raw grain samples, Figures 7 to 12 As shown, the raw grain sample reduction device 3 also 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 connected to the first sub-material cavity. The second discharge pipe 35 is connected to the second sub-material cavity. The third discharge pipe 36 is connected to the third sub-material cavity. The fourth discharge pipe 37 is connected to the fourth sub-material cavity. The fifth discharge pipe 38 is connected to the fifth sub-material cavity.

[0095] In this embodiment, the first discharge pipe 34 is connected to the first sub-material chamber, and is used to export the raw grain sample in the first sub-material chamber. The second discharge pipe 35 is connected to the second sub-material chamber, and is used to export the raw grain sample in the second sub-material chamber. The third discharge pipe 36 is connected to the third sub-material chamber, and is used to export the raw grain sample in the third sub-material chamber. The fourth discharge pipe 37 is connected to the fourth sub-material chamber, and is used to export the raw grain sample in the fourth sub-material chamber. The fifth discharge pipe 38 is connected to the fifth sub-material chamber. Since the fifth sub-material chamber receives samples from six discharge ports, the fifth discharge pipe 38 will be responsible for exporting a relatively large amount of raw grain samples in this sub-material chamber, thereby achieving a reduction ratio of 1:1:1:1:6.

[0096] Alternatively, if Figure 8 and Fig. 9 As shown, 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 extend in different directions away from one end of the material cavity.

[0097] This design allows each discharge pipe to independently export the raw grain sample in its corresponding sub-cavity without interfering or affecting each other. For example, when it is necessary to export samples from multiple sub-cavities at the same time, the staff can easily operate through different discharge pipes without worrying about sample confusion or cross contamination.

[0098] In addition, the discharge pipe extends in different directions, which also facilitates the layout and installation of the equipment. In practical applications, the discharge pipe can be flexibly placed in a suitable position according to specific site conditions and operation requirements to facilitate operation and observation by staff.

[0099] In some embodiments, the raw grain sample reduction device 3 further includes: a locking shaft 39. A connecting seat 313 is provided on the first shell 311 and the second shell 312, and the locking shaft 39 is rotatably passed through the connecting seat 313 and the external structure.

[0100] Specifically, the locking shaft 39 is rotatably provided on the connecting seat 313 and the external structure, and such a design allows the user to lock or loosen the first shell 311 and the second shell 312 by operating the locking shaft 39. A handle is provided at one end of the locking shaft 39 for easy gripping, and the user only needs to gently turn the handle to easily lock or loosen the shell.

[0101] When the first shell 311 and the second shell 312 are locked, the connection between them becomes very stable, which can not only prevent the raw grain sample in the material chamber from leaking, but also ensure that the material distribution wheel 32 maintains a stable operating environment during the rotation process. When cleaning, maintenance or replacement of parts is required, the user only needs to reversely rotate the handle of the locking shaft 39 to easily separate the two shells, which provides convenience for maintenance work.

[0102] In addition, if Figure 8 and Fig. 9 As shown, the raw grain sample reduction device 3 also includes: a hopper 314 and a feed pipe 315; the hopper 314 is located on one side of the sub-bin 31, and the hopper 314 is connected to the feed port through the feed pipe 315. The design of the hopper 314 allows the user to easily pour the raw grain sample into it, so as to prepare for the subsequent reduction operation. In order to smoothly introduce the raw grain sample in the hopper 314 into the material cavity of the sub-bin, the device is also equipped with a feed pipe 315. One end of the feed pipe 315 is connected to the bottom of the hopper 314, and the other end is connected to the feed port of the sub-bin 31. When the raw grain samples in the hopper 314 accumulate to a certain extent, they will naturally flow into the material cavity of the sub-bin through the feed pipe 315, and then be reduced by the sub-bin wheel 32 according to a predetermined ratio. The design of the hopper 314 and the feed pipe 315 not only simplifies the introduction process of the raw grain sample and improves the work efficiency, but also ensures the continuity and stability of the reduction operation.

[0103] Among them, the feed pipe 315 is provided with a third valve 316. The precise control function of the third valve 316 allows the user to adjust the flow rate and entry speed of the sample at any time as needed. This adjustment is not only conducive to ensuring the stability and continuity of the reduction process, but also helps to improve the accuracy and consistency of the reduction results. By accurately controlling the opening degree of the third valve 316, the user can ensure that the raw grain sample flows into the sub-bin at an appropriate speed, thereby avoiding the accumulation or overflow of the sample in the material chamber, 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, the user 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 hopper 314 from continuing to flow into the sub-bin after the equipment stops running, ensuring the smooth cleaning and maintenance of the reduction device.

[0104] In some embodiments, Fig.10 and Fig.11 As 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.

[0105] In this embodiment, Fig.11 As shown, one axial end face of the 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 six discharge ports 321, which are connected to the fifth sub-material cavity. The radial direction of the dividing wheel 32 is provided with three discharge ports, which are respectively connected to the second sub-material cavity, the third sub-material cavity, and the fourth sub-material cavity.

[0106] In some embodiments, Figure 8 and Fig. 9As 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.
