Description

Technical Field

[0001] The utility model relates to the field of grain and oil inspection, in particular to a double-cone unidirectional mixing one-point-five-portioning system. Background Art

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

[0003] In the current market, although there are some mixing and sample reduction 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 and sample reduction methods often rely on manual operation, which is not only inefficient but also easily affected by human factors, resulting in unstable mixing effects and further affecting the accuracy of inspection results. At the same time, manual operation also involves a large labor intensity and reduces work efficiency.

[0052] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model embodiment. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0053] The utility model provides a double cone one-way mixing one-point five-point material system, such as Figure 1 and Figure 4 As shown, the double-cone one-way mixing one-division-five-division system includes: a raw grain sample mixing device 1 and a raw grain sample shrinking device 3. The raw grain sample mixing device 1 includes: a mixing bin 11, a cover plate 12, a first driving mechanism 13 and a second driving mechanism 14. The mixing bin 11 is formed with a first cavity for loading raw grain samples, and the mixing bin 11 is provided with a material port connected to the first cavity; the first driving mechanism 13 is transmission-connected to the cover plate 12, and the first driving mechanism 13 is used to drive the cover plate 12 to move between a first position covering the material port and a second position where the cover plate 12 exposes the material port. The second driving mechanism 14 is transmission-connected to the mixing bin 11, and the second driving mechanism 14 is used to drive the mixing bin 11 to rotate, so that the raw grain samples are evenly mixed in the first cavity. The raw grain sample shrinking device 3 is used to shrink the mixed raw grain samples. As shown Figures 5 to 9As shown, the raw grain sample reduction device 3 includes: a material dividing bin 31, a material dividing wheel 32 and a third driving mechanism 33. The material dividing bin 31 is formed with a material cavity and a feed port. The material 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 material 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 for driving the dividing wheel 32 to rotate in the material chamber, 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-material chambers through the discharge port 321. By setting different numbers of discharge ports 321, a 1:6 reduction can be achieved.

[0054] Specifically, the mixing bin 11 is a container for loading raw grain samples, and its design also takes into account the mixing effect and ease of operation. The mixing bin is made of high-strength material to ensure that it will not deform or break during the mixing process. At the same time, the interior of the mixing bin is smooth and has no dead corners to prevent samples from being retained during the mixing process. The cover plate 12 not only plays the role of closing the mixing bin, but also has the functions of dust and moisture resistance. When the first drive mechanism 13 drives the cover plate 12 to move from the first position to the second position, the material port is fully opened, which is convenient for adding or removing raw grain samples from the mixing bin. At the same time, a handle or operating rod can be set on the cover plate 12 to facilitate easy movement by the operator. The first drive mechanism 13 adopts an electric or pneumatic drive mode to ensure that the cover plate 12 can move quickly and stably between the first position and the second position. The drive mechanism also has overload protection and emergency stop functions to ensure safe operation. The second drive mechanism 14 drives the mixing bin 11 to rotate. In order to ensure uniform mixing, the second drive mechanism can use a high-precision first motor and reducer combination to achieve stable rotation speed and torque output. At the same time, the second driving mechanism 14 also has a speed adjustable function, which can be adjusted according to the mixing requirements of different samples. After mixing, the raw grain sample can be introduced into the raw grain sample reduction device 3 for reducing the mixed raw grain sample. The distribution bin 31 is the main structure of the entire device, and a material cavity for reducing the raw grain sample is formed inside it. A feed port is provided on one side of the material cavity, which is used to introduce the raw grain sample to be reduced into the device. The distribution wheel 32 can not only rotate freely, but also its design is cleverly matched with the side wall of the material cavity, dividing the material cavity into at least two sub-cavities. A second cavity is formed inside the distribution 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 also provided on the distribution wheel 32, and these discharge ports 321 are all connected to the second cavity. When the distribution 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 a specific discharge port 321. This design enables 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 of the sub-cavities is only connected to one discharge port 321, while the other sub-cavity is connected to six discharge ports 321. This design cleverly achieves the reduction of the raw grain sample, 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. In order to drive the rotation of the distribution wheel 32, the device is also equipped with a third drive mechanism 33. The third drive mechanism 33 is connected to the distribution wheel 32 in a transmission manner, and ensures that the distribution wheel 32 rotates in the cavity at a predetermined speed and direction by providing stable power. In this way, the raw grain sample can be accurately distributed to different sub-cavities through the discharge port 321, achieving efficient and accurate reduction.

[0055] The whole raw grain sample mixing device can also be equipped with an intelligent control system, which can realize precise control of the first driving mechanism 13 and the second driving mechanism 14. The operator can set the mixing parameters (such as rotation speed, mixing time, etc.) through the control panel or remote control to realize automatic operation. In addition, the control system can also monitor the operating status of the equipment in real time, and automatically alarm and stop operation if a fault or abnormal situation occurs.

[0056] The double-cone unidirectional mixing one-point-five-point material 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 the second driving mechanism to rotate the mixing bin, so as to achieve uniform mixing, avoid the problem of local uneven mixing that may occur in the traditional mixing method, and can use the raw grain sample reduction device to reduce the mixed raw grain sample, thereby improving the convenience and efficiency of mixing and reducing the raw grain sample. The first driving mechanism is connected to the cover plate in a transmission manner, and the opening and closing of the cover plate can be conveniently controlled. When it is necessary to add or remove the raw grain sample, the first driving mechanism can quickly move the cover plate from the position of blocking the material port to the position of exposing the material port, thereby improving the convenience and efficiency of operation. In addition, the raw grain sample reduction device can efficiently distribute the raw grain sample to at least 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 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 has a simple and clear structure. The reduction process can be completed by driving the rotation of the dividing wheel through the first driving mechanism. No complicated operation steps and manual intervention are required, which reduces the difficulty of operation and labor costs. Since the dividing wheel is provided with multiple discharge ports connected to the cavity, and each discharge port accurately corresponds to a sub-cavity, it can ensure that the sample quantity ratio in each sub-cavity after reduction is accurate and correct, meeting the needs of scientific experiments and production.

[0057] It should be noted that in order to meet different usage requirements, the raw grain sample mixing device can also be equipped with the following extended functions: for example, a weighing sensor is set in the mixing bin 11 to monitor the weight change of the raw grain sample in the mixing bin 11 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 11 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 11 to realize the automatic cleaning function of the equipment and reduce the labor intensity of manual cleaning.

[0058] In some embodiments, Figure 1As shown in the figure, the mixing bin 11 includes: a first hopper 111, a second hopper 112, a third hopper 113, and a fourth hopper 114 that are connected in sequence. A first cavity is formed in the first hopper 111, the second hopper 112, the third hopper 113, and the fourth hopper 114, and a material inlet is provided on the first hopper 111; the second driving mechanism 14 is connected to at least one of the first hopper 111, the second hopper 112, the third hopper 113, and the fourth hopper 114.

[0059] In this embodiment, since the mixing bin 11 is divided into multiple hoppers, the raw grain samples in each hopper will experience multiple mixing and exchanges during rotation, thus achieving a more uniform and efficient mixing effect. The segmented design enables the operator to more conveniently observe the mixing situation in each hopper, and thus make adjustments and controls according to the actual situation. At the same time, sensors and other devices can also be set on each hopper to achieve automatic monitoring and control.

[0060] In terms of driving, the second driving mechanism 14 is connected to at least one of the first hopper 111, the second hopper 112, the third hopper 113, and the fourth hopper 114. This connection method can be flexibly adjusted according to specific mixing requirements and equipment design. For example, the second driving mechanism 14 can be connected to the first hopper 111, and the rotation of the first hopper 111 is used to drive the rotation of the entire mixing bin; or the second driving mechanism 14 can be connected to multiple hoppers to achieve more complex mixing actions and effects.

[0061] In some embodiments, as Figures 1 to 3 shown, the mixing bin 11 further includes: a dispersion mechanism 115. The dispersion mechanism 115 is arranged in the first cavity corresponding to the second hopper 112 and / or the third hopper 113, and the dispersion mechanism 115 is used to disperse the raw grain samples entering the fourth hopper 114 from the first hopper 111 or the raw grain samples entering the first hopper 111 from the fourth hopper 114 during the rotation of the mixing bin 11.

[0062] Specifically, when the mixing bin 11 starts to rotate, the raw grain samples will flow between the first hopper 111, the second hopper 112, the third hopper 113 and the fourth hopper 114 under the action of gravity and centrifugal force. The dispersing mechanism 115 can further break up and disperse these flowing samples, thus preventing the samples from forming lumps or agglomerates during the flowing process and ensuring that the samples can be evenly mixed throughout the mixing bin. The specific design of the dispersing mechanism 115 can be adjusted according to actual needs. For example, structures such as rotating blades, stirring rods or vibrators can be adopted. These structures can generate appropriate shear forces or impact forces when the mixing bin rotates to effectively disperse the samples. By introducing the dispersing mechanism 115, this raw grain sample mixing device can further improve the mixing effect and ensure that the raw grain samples are more evenly and thoroughly mixed in the mixing bin. At the same time, this design also increases the adaptability and flexibility of the equipment and can handle raw grain samples of different types and characteristics.

[0063] In some embodiments, as Figures 1 to 3 shown, the dispersing mechanism 115 includes: a double cone 1151. One end of the double cone 1151 is located in the second hopper 112, and a sample dividing grid 1154 is formed at the gap between the double cone 1151 and the second hopper 112 and / or the third hopper 113. The sample dividing grid 1154 is provided with an opening on the side facing the first hopper 111 and is communicated with the inside of the double cone 1151. The other end of the double cone 1151 is located in the third hopper 113, and a dispersing opening 1152 is provided at the other end of the double cone 1151. A dispersing opening cover plate 1153 is provided at the dispersing opening 1152. In the case where the second hopper 112 rotates above the third hopper 113, the dispersing opening cover plate 1153 exposes the dispersing opening 1152. In the case where the third hopper 113 rotates above the second hopper 112, the dispersing opening cover plate 1153 covers the dispersing opening 1152.

[0064] Specifically, when the second hopper 112 rotates directly above the third hopper 113, the dispersing opening cover plate 1153 will automatically adjust its position to expose the dispersing opening 1152. At this time, the raw grain samples located in the first hopper 111 start to flow into the second hopper 112. As the samples continue to enter, they will encounter the sample dividing grid 1154. The ingenious design of the sample dividing grid 1154 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 1151 through the opening of the sample dividing grid 1154 and are then exported to the third hopper 113 through the dispersing opening 1152. These samples will eventually flow into the fourth hopper 114 to complete a circulation cycle.

[0065] For another part of the samples, after being dispersed by the sample dividing grid 1154, they will directly fall into the third hopper 113. This part of the samples will also eventually enter the fourth hopper 114, but their flow path is more direct and does not need to pass through the interior of the double cone 1151. Through the method of cone dispersion by free fall, different sample particles in the samples are evenly distributed to achieve the purpose of uniform mixing.

[0066] Next, when the third hopper 113 rotates to directly above the second hopper 112, the dispersion port cover plate 1153 will adjust its position again to block the dispersion port 1152. At this time, the raw grain samples in the fourth hopper 114 start to flow into the third hopper 113. These samples will be dispersed again through the back of the sample dividing grid 1154 and then evenly enter the second hopper 112. Finally, they will flow into the first hopper 111 to complete another circulation in one direction.

[0067] During the whole process, the coordinated work between the dispersion mechanism 115 and the hoppers not only ensures the uniform dispersion of the raw grain samples but also realizes the continuous and efficient flow of the samples. This design greatly improves the efficiency and stability of the raw grain processing system and provides a reliable guarantee for subsequent processing and detection work.

[0068] It should be noted that generally, there are multiple sample dividing grids 1154. The multiple sample dividing grids 1154 are arranged at intervals in sequence along the circumferential direction of the double cone 1151, and the side walls of adjacent sample dividing grids 1154 form a hollow sample dividing grid. The design of the multiple sample dividing grids 1154 enables the raw grain samples to be dispersed more times during the flow process, thereby improving the uniformity and efficiency of mixing. This design is particularly useful when it is necessary to efficiently mix raw grain samples of different types or characteristics and can meet the requirements of different processes and products.

[0069] In a specific embodiment, the double cone 1151 cooperates with the side wall of the hopper to form a first sample dividing grid and a second sample dividing grid. The first sample dividing grid is provided with an opening on the side facing the first hopper 111, and the second sample dividing grid is a hollow sample dividing grid. Thus, after the material is evenly dispersed by freely falling onto the double cone 1151, it enters the first sample dividing grid or the second sample dividing grid. Subsequently, a part of the samples freely fall along the outside of the double cone 1151 through the second sample dividing grid, and another part of the samples enter the interior of the double cone 1151 through the first sample dividing grid and then fall. The two parts of the samples are mixed, and through the method of cone dispersion by free fall, different sample particles in the samples are evenly distributed to achieve the purpose of uniform mixing.

[0070] In some embodiments, such as Figure 1 and Figure 2As shown, the mixing bin 11 further includes: a first valve 116. The first valve 116 is arranged between the first hopper 111 and the second hopper 112. The first hopper 111 is communicated with the second hopper 112 through the first valve 116.

[0071] In this embodiment, the main function of the first valve 116 is to control whether the first hopper 111 and the second hopper 112 are communicated, and at the same time control the flow rate and speed of the raw grain sample entering the second hopper 112 from the first hopper 111. By precisely adjusting the opening degree of the first valve 116, the operator can flexibly control the mixing speed and mixing ratio of the raw grain sample according to the actual production requirements.

[0072] This design not only improves the flexibility and adaptability of the mixing bin 11, 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 116 is particularly important.

[0073] In addition, the introduction of the first valve 116 also facilitates the maintenance and cleaning of the mixing bin 11. 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, thus avoiding unnecessary impacts on the entire raw grain sample mixing device.

[0074] In another embodiment, as Figure 1 and Figure 2 shown, the mixing bin 11 further includes: a first valve 116 and a second valve 117. The first valve 116 and the second valve 117 can adopt solenoid valves. The first valve 116 is arranged between the first hopper 111 and the second hopper 112. The first hopper 111 is communicated with the second hopper 112 through the first valve 116. The second valve 117 is arranged between the third hopper 113 and the fourth hopper 114, and the third hopper 113 is communicated with the fourth hopper 114 through the second valve 117. The addition of the first valve 116 and the second valve 117 provides more flexibility and controllability for the mixing of the raw grain sample. 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 the raw grain sample 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.

[0075] Specifically, when the second driving mechanism 14 controls the second hopper 112 to rotate to directly above the third hopper 113, the dispersion port cover plate 1153 will automatically adjust its position to expose the dispersion port 1152. At this time, if a feeding instruction is received, the first driving mechanism 13 controls the cover plate 12 to move to the second position to expose the material port. After the sample information is identified by scanning the code, the sample enters the first hopper 111, and then the first driving mechanism 13 controls the cover plate 12 to move to the first position to block the material port.

[0076] Then, the first valve 116 and the second valve 117 are opened. In addition, the sample located in the first hopper 111 starts to flow into the second hopper 112. As the samples continue to enter, they will encounter the sample dividing grid 1154. The ingenious design of the sample dividing grid 1154 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 1151 through the open ends of the sample dividing grid 1154, and then are led out through the dispersion port 1152 to the third hopper 113. These samples will eventually flow into the fourth hopper 114 to complete a circulation cycle. For the other part of the samples, after being dispersed by the sample dividing grid 1154, they will directly fall into the third hopper 113. This part of the samples will also eventually enter the fourth hopper 114, but their flow path is more direct and does not need to pass through the interior of the double cone 1151.

[0077] Next, the first valve 116 and the second valve 117 are closed, and the second driving mechanism 14 is used to control the mixing bin 11 to rotate. When the third hopper 113 rotates to directly above the second hopper 112, the dispersion port cover plate 1153 will adjust its position again to block the dispersion port 1152. At this time, the first valve 116 and the second valve 117 are opened, and the raw grain samples located in the fourth hopper 114 start to flow into the third hopper 113. These samples will be dispersed again through the back of the sample dividing grid 1154 and then evenly enter the second hopper 112. They will flow into the first hopper 111 to complete a circulation cycle in the other direction. Finally, after repeating the above operations for the pre-designed number of mixing times, the first hopper 111 is lowered, the cover plate 12 is opened, and the sample is placed into the raw grain sample reduction device 3 to complete the operation.

[0078] Based on the above embodiments, in some embodiments, as Figure 1 and Figure 2 shown, the first driving mechanism 13 includes: a cylinder 131. The movable end of the cylinder 131 is connected to the cover plate 12, and the cylinder 131 is used to drive the cover plate 12 to move between the first position and the second position.

[0079] In this embodiment, the first driving mechanism 13 uses a cylinder 131 as its core driving element. The movable end of the cylinder 131 is directly connected to the cover plate 12, and the telescopic movement of the cylinder 131 is used to drive the cover plate 12 to move between the first position and the second position.

[0080] For example, when the cylinder 131 is in the retracted state, the cover plate 12 is in the closed position, completely covering the feed opening of the first hopper 111 and preventing the raw grain sample from entering the mixing bin from the first hopper 111.

[0081] When the cylinder 131 is in the extended state, the cover plate 12 is moved away from the feed opening of the first hopper 111, exposing the feed opening and allowing the raw grain sample to enter the mixing bin from the first hopper 111 for mixing.

[0082] This design allows the operator to conveniently control the feeding process of the mixing bin by controlling the telescopic movement of the cylinder 131, improving the flexibility and automation of the operation.

[0083] Similarly, based on the above embodiment, in some embodiments, as Figure 1 and Figure 2 shown, the second driving mechanism 14 includes: a first motor 141. The rotating end of the first motor 141 is connected to the mixing bin 11 and is used to drive the mixing bin 11 to rotate. The first motor 141 can set the rotation direction as needed to ensure that the mixing bin 11 can rotate in a predetermined direction. The rotation speed of the first motor 141 can be precisely adjusted through the control system to adapt to the mixing requirements of different raw grain samples. The rotation of the mixing bin 11 can promote the flow and mixing of the raw grain sample between the hoppers, improving the uniformity and efficiency of the mixing. The use of the first motor 141 ensures the stability and reliability of the rotation process and provides strong power support for the mixing process.

[0084] In this embodiment, as Figure 1 and Figure 2 shown, the second driving mechanism 14 further includes: a bracket 142. One end of the bracket 142 is connected to the first driving mechanism 13, the other end of the bracket 142 is connected to the mixing bin 11, and the rotating end of the first motor 141 is connected to the middle of the bracket 142. When the first motor 141 rotates, it transmits the rotational force to the mixing bin 11 through the bracket 142, thereby driving the mixing bin 11 to rotate. Since one end of the bracket 142 is connected to the first driving mechanism 13, this design also ensures the coordination between the feeding process (i.e., the opening and closing of the cover plate 12) and the rotation of the mixing bin 11.

[0085] Specifically, when it is necessary to add the raw grain sample to the mixing bin 11, the cylinder of the first driving mechanism 13 extends, pushing the cover plate 12 away from the material opening of the first hopper 111 to expose the material opening. When it is necessary to stop adding the raw grain sample, the cylinder of the first driving mechanism 13 contracts, pulling the cover plate 12 back to the closed position to prevent the raw grain sample from continuing to enter the mixing bin. Then, the first motor 141 starts to rotate, driving the mixing bin 11 to rotate through the bracket 142. The raw grain sample is fully mixed during the rotation of the mixing bin. The first motor 141 can continue to rotate for a period of time to ensure that the raw grain sample in the mixing bin is fully mixed.

[0086] In some embodiments, as Figures 5 to 9 shown, the sub-material cavities are the first sub-material cavity, the second sub-material cavity, the third sub-material cavity, the fourth sub-material cavity, and the fifth sub-material cavity respectively. The first sub-material cavity, the second sub-material cavity, the third sub-material cavity, and the fourth sub-material cavity are all communicated with their corresponding one discharge port 321, and the fifth sub-material cavity is communicated with its corresponding six discharge ports 321.

[0087] Specifically, among these five sub-material cavities, the design principles of the first sub-material cavity, the second sub-material cavity, the third sub-material cavity, and the fourth sub-material cavity are similar, and they are all directly communicated with their corresponding one specific discharge port 321. When the material distribution wheel 32 rotates in the material cavity, these sub-material cavities will receive the raw grain sample flowing out from the second cavity through their respective discharge ports. Since each sub-material cavity is only connected to one discharge port, the amount of sample they receive is relatively small, but it is sufficient to meet specific experimental or production requirements.

[0088] The design of the fifth sub-material cavity is different. It is connected to six discharge ports 321. This means that when the material distribution wheel 32 rotates, the fifth sub-material cavity will receive the raw grain sample from six discharge ports at the same time. Therefore, the amount of sample it receives is much more than that of other sub-material cavities. This design enables the fifth sub-material cavity to store a large amount of quartered raw grain sample to meet the needs of large-scale experiments or production.

[0089] 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 1:1:1:1:6), improving the flexibility and practicality of the equipment. At the same time, since each sub-material cavity is directly communicated with its corresponding discharge port, the quartering process is more accurate and reliable, ensuring the accuracy of experimental and production results.

[0090] In some embodiments, as Figures 5 to 9As shown in the figure, the material distribution bin 31 includes: a first housing 311, a second housing 312, and a first discharge partition, a second discharge partition, a third discharge partition, and a fourth discharge partition that are sequentially arranged at intervals along the circumferential direction of the material distribution wheel 32; the first housing 311 and the second housing 312 are mutually butted to form a material cavity, the first housing 311 and the first discharge partition form a first sub-material cavity, the first discharge partition and the second discharge partition form a second sub-material cavity in the material cavity, the second discharge partition and the third discharge partition form a third sub-material cavity in the material cavity, the third discharge partition and the fourth discharge partition form a fourth sub-material cavity in the material cavity, and the fourth discharge partition and the second housing 312 form a fifth sub-material cavity in the material cavity.

[0091] In this embodiment, the first housing 311 and the second housing 312 are mutually butted, and the two are closely matched to jointly form a closed material cavity. This material cavity is the area for storing and preparing to distribute the raw grain samples. The space between the first housing 311 and the first discharge partition is defined as the first sub-material cavity. This sub-material cavity is used to receive and store the first part of the raw grain samples distributed from the material cavity. Immediately afterwards, the space between the first discharge partition and the second discharge partition forms an independent area in the material cavity, which is the second sub-material cavity. It is also used to receive and store the second part of the raw grain samples distributed from the material cavity. The second discharge partition and the third discharge partition form a third sub-material cavity in the material cavity for storing the third part of the raw grain samples. Similarly, the space between the third discharge partition and the fourth discharge partition constitutes the fourth sub-material cavity for storing the fourth part of the raw grain samples. Finally, the space between the fourth discharge partition and the second housing 312 forms a fifth sub-material cavity in the material cavity. This sub-material cavity is used to receive and store the fifth part of the raw grain samples distributed from the material cavity.

[0092] For the convenience of discharging the corresponding amount of raw grain samples, as Figures 5 to 9 shown, the raw grain sample reduction device 3 further includes: a first discharge pipe 34, a second discharge pipe 35, a third discharge pipe 36, a fourth discharge pipe 37, and a fifth discharge pipe 38. The first discharge pipe 34 is communicated with the first sub-material cavity. The second discharge pipe 35 is communicated with the second sub-material cavity. The third discharge pipe 36 is communicated with the third sub-material cavity. The fourth discharge pipe 37 is communicated with the fourth sub-material cavity. The fifth discharge pipe 38 is communicated with the fifth sub-material cavity.

[0093] In this embodiment, the first discharge pipe 34 is connected to the first sub-material chamber and is used to discharge 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 discharge 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 discharge 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 discharge 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 the samples from six discharge ports, the fifth discharge pipe 38 will be responsible for discharging the relatively large amount of raw grain sample in this sub-material chamber, thereby achieving a quartering ratio of 1:1:1:1:6.

[0094] Optionally, as Figure 5 and Figure 6 shown, the ends of the first discharge pipe 34, the second discharge pipe 35, the third discharge pipe 36, the fourth discharge pipe 37, and the fifth discharge pipe 38 away from the material chamber extend in different directions.

[0095] This design enables each discharge pipe to independently discharge the raw grain sample in its corresponding sub-material chamber without interference or influence on each other. For example, when it is necessary to discharge 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.

[0096] In addition, the discharge pipes extending in different directions also facilitate the layout and installation of the equipment. In practical applications, according to the specific site conditions and operation requirements, the discharge pipes can be flexibly placed in appropriate positions to facilitate the operation and observation of the staff.

[0097] In some embodiments, the raw grain sample quartering device 3 further includes: a locking shaft 39. Connecting seats 313 are provided on the first housing 311 and the second housing 312, and the locking shaft 39 is rotatably inserted through the connecting seats 313 and the external structure.

[0098] Specifically, the locking shaft 39 is rotatably inserted through the connecting seats 313 and the external structure. Such a design allows the user to lock or unlock the first housing 311 and the second housing 312 by operating the locking shaft 39. At one end of the locking shaft 39, there is a handle for easy gripping. The user can simply turn the handle to easily lock or unlock the housing.

[0099] When the first housing 311 and the second housing 312 are locked, their connection will become very stable, which can not only prevent the leakage of the raw grain sample in the material chamber but also ensure a stable operating environment for the material distribution wheel 32 during rotation. 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.

[0100] In addition, as Figure 5 and Figure 6 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 distribution bin 31, and the fifth hopper 314 is communicated with the feed port through the feed pipe 315. The design of the fifth hopper 314 enables users to conveniently pour the raw grain sample into it, preparing for the subsequent reduction operation. In order to smoothly introduce the raw grain sample in the fifth hopper 314 into the cavity of the distribution bin, the device is also equipped with a feed pipe 315. One end of the feed pipe 315 is communicated with the bottom of the fifth hopper 314, and the other end is connected to the feed port of the distribution bin 31. When the raw grain sample in the fifth hopper 314 accumulates to a certain extent, they will naturally flow into the cavity of the distribution bin through the feed pipe 315, and then be reduced by the distribution wheel 32 according to a predetermined ratio. The design of the fifth hopper 314 and the feed pipe 315 not only simplifies the introduction process of the raw grain sample, improves the work efficiency, but also ensures the continuity and stability of the reduction operation.

[0101] Wherein, a third valve 316 is provided on the feed pipe 315. The precise control function of the third valve 316 enables users to adjust the flow rate and entry speed of the sample at any time according to needs. This adjustment not only helps to ensure the stability and continuity of the reduction process, but also contributes to improving the accuracy and consistency of the reduction result. By precisely controlling the opening degree of the third valve 316, users can ensure that the raw grain sample flows into the distribution bin at an appropriate speed, thereby avoiding the accumulation or overflow of the sample in the cavity and ensuring the smooth progress of the reduction process. Secondly, the introduction of the third valve 316 also enhances the safety of the raw grain sample reduction device 3. During the reduction process, if an abnormal situation occurs or an emergency stop operation is required, users can quickly close the third valve 316 to cut off the inflow of the sample, thereby avoiding possible dangers or losses. In addition, the third valve 316 can also prevent the raw grain sample in the fifth hopper 314 from continuing to flow into the distribution bin after the equipment stops running, ensuring the smooth progress of the cleaning and maintenance work of the reduction device.

[0102] In some embodiments, as Figure 7 and Figure 8As 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.

[0103] In this embodiment, Figure 9 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.

[0104] In some embodiments, Figure 5 and Figure 6 As shown, the third driving mechanism 33 includes: a second motor 331 and a reducer 332. The rotating shaft of the second motor 331 is connected to the dividing wheel 32 through the reducer 332. As the core component of the entire drive system, the second 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 second 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 second 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 second 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 second motor 331 is connected to the material distribution wheel 32 through the reducer 332, forming a complete power transmission path. When the second 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 achieving the distribution of the raw grain sample.
