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-division and four-division 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 and reducing 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 double-cone one-way mixing one-dividing and four-dividing 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.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[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 four-point material system, such as Figure 1 and Figure 4 As shown, the double-cone one-way mixing one-division and four-division material 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 exposing 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 6As shown in the figure, the raw grain sample reduction device 3 includes: a material distribution bin 31, a material distribution wheel 32, and a third driving mechanism 33. The material distribution bin 31 is formed with a material cavity and a feed inlet. The material distribution wheel 32 is rotatably arranged in the material cavity, and cooperates with the side wall of the material cavity to divide the material cavity into at least three sub-material cavities. The material distribution wheel 32 is formed with a second cavity and a plurality of discharge ports 321 communicated with the second cavity. Each discharge port 321 is communicated with the feed inlet through the second cavity. One of the sub-material cavities is communicated with two discharge ports 321, another sub-material cavity is communicated with two discharge ports, and yet another sub-material cavity is communicated with five discharge ports 321. The third driving mechanism 33 is in transmission connection with the material distribution wheel 32, and is used to drive the material distribution wheel 32 to rotate in the material cavity, so that the raw grain sample introduced from the feed inlet enters the second cavity and then enters the second cavity. In the case where the third driving mechanism 33 drives the material distribution wheel 32 to rotate, the raw grain sample can enter different sub-material cavities through the discharge ports 321. By setting different numbers of discharge ports 321, the reduction of 2:2:5 is completed.

[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 operation convenience. The mixing bin is made of high-strength materials to ensure that it will not deform or break during the mixing process. At the same time, the inside of the mixing bin is smooth without dead corners to avoid the retention of samples during the mixing process. The cover plate 12 not only plays a role in closing the mixing bin, but also has the functions of dust prevention and moisture prevention. When the first driving mechanism 13 drives the cover plate 12 to move from the first position to the second position, the material port is completely opened, which is convenient for adding or taking out raw grain samples into or from the mixing bin. At the same time, a handle or an operating rod can be arranged on the cover plate 12 to facilitate the operator to move it easily. The first driving mechanism 13 adopts an electric or pneumatic driving method to ensure that the cover plate 12 can move quickly and stably between the first position and the second position. This driving mechanism also has overload protection and emergency stop functions to ensure operation safety. The second driving mechanism 14 drives the mixing bin 11 to rotate. In order to ensure uniform mixing, the second driving mechanism 14 can adopt a combination of a high-precision first motor and a reducer to achieve stable rotational speed and torque output. At the same time, the second driving mechanism 14 also has a speed adjustable function and 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.

[0055] As Figures 5 to 9As shown in the figure, the feeding bin 31 serves as the main structure of the entire device, and a material cavity for reducing and dividing the original grain sample is formed inside it. One side of the material cavity is provided with a feeding port for introducing the original grain sample to be reduced and divided into the device. The dividing wheel 32 can not only rotate freely, but its design also ingeniously cooperates with the side wall of the material cavity to divide the material cavity into at least three sub-material cavities. A second cavity is formed inside the dividing wheel 32, and this second cavity is connected to the feeding port of the material cavity. More importantly, a plurality of discharge ports 321 are provided on the dividing wheel 32, and these discharge ports 321 are all connected to the second cavity. When the dividing wheel 32 rotates, the original grain sample introduced from the feeding port will first enter the second cavity, and then enter different sub-material cavities through specific discharge ports 321. This design enables the original grain sample to be effectively distributed into different sub-material cavities during the rotation of the dividing wheel 32. Specifically in the design of the discharge ports 321, one sub-material cavity is connected to two discharge ports 321, another sub-material cavity is connected to two discharge ports 321, and yet another sub-material cavity is connected to five discharge ports 321. This design ingeniously realizes the reduction and division of the original grain sample, making the ratio of the sample amount in one sub-material cavity to the sample amounts in other sub-material cavities reach a ratio of 2:2:5. In order to drive the rotation of the dividing wheel 32, a third driving mechanism 33 is also equipped in the device. The third driving mechanism 33 is in transmission connection with the dividing wheel 32, and provides stable power to ensure that the dividing wheel 32 rotates in the material cavity at a predetermined speed and direction. In this way, the original grain sample can be accurately distributed into different sub-material cavities through the discharge ports 321, realizing efficient and accurate reduction and division.

[0056] The entire original grain sample mixing device can also be equipped with an intelligent control system, which can achieve precise control of the first driving mechanism 13 and the second driving mechanism 14. The operator can set mixing parameters (such as rotation speed, mixing time, etc.) through the control panel or remote control to achieve automated operation. In addition, the control system can also monitor the operating status of the equipment in real time. If a fault or abnormal situation occurs, it can automatically alarm and stop running.

[0057] The double-cone unidirectional mixing one-division and four-division 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 driving the mixing bin to rotate, thereby achieving uniform mixing, avoiding 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 three sub-material chambers through the rotation of the material distribution wheel and the cooperation with the side wall of the material chamber, wherein one sub-material chamber is connected to two discharge ports, another sub-material chamber is connected to two discharge ports, and another sub-material chamber is connected to five discharge ports, thereby achieving an accurate reduction ratio of 2:2:5. This reduction method is faster and more accurate than the traditional manual reduction method. The device structure is simple and clear. The reduction process can be completed by driving the rotation of the dividing wheel through the third 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 second 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.

[0058] 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.

[0059] In some embodiments, Figure 1 As shown, the mixing bin 11 includes: a first hopper 111, a second hopper 112, a third hopper 113 and a fourth hopper 114 which 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 port 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.

[0060] 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.

[0061] 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 driven 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.

[0062] 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. 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.

[0063] 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 dispersion mechanism 115 can further break up and disperse these flowing samples, thereby preventing the samples from forming lumps or agglomerates during the flow process and ensuring that the samples can be evenly mixed throughout the mixing bin. The specific design of the dispersion mechanism 115 can be adjusted according to actual needs. For example, structures such as rotating blades, stirring rods, or vibrators can be used. These structures can generate appropriate shear forces or impact forces during the rotation of the mixing bin to effectively disperse the samples. By introducing the dispersion mechanism 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 different types and characteristics of raw grain samples.

[0064] In some embodiments, as Figures 1 to 3As shown in the figure, the dispersion mechanism 115 includes: a double cone 1151. One end of the double cone 1151 is located in the second hopper 112. Sampling grids 1154 are formed at the gaps between the double cone 1151 and the second hopper 112 and / or the third hopper 113. The sampling grids 1154 are provided with openings on the side facing the first hopper 111 and are communicated with the inside of the double cone 1151. The other end of the double cone 1151 is located in the third hopper 113. A dispersion port 1152 is provided at the other end of the double cone 1151, and a dispersion port cover plate 1153 is provided at the dispersion port 1152. When the second hopper 112 rotates above the third hopper 113, the dispersion port cover plate 1153 exposes the dispersion port 1152. When the third hopper 113 rotates above the second hopper 112, the dispersion port cover plate 1153 covers the dispersion port 1152.

[0065] Specifically, when the second hopper 112 rotates 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, the raw grain sample located in the first hopper 111 begins to flow into the second hopper 112. As the samples continue to enter, they will encounter the sampling grids 1154. The ingenious design of the sampling grids 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 openings of the sampling grids 1154, and then are led out to the third hopper 113 through the dispersion port 1152. These samples will eventually flow into the fourth hopper 114 to complete a circulation cycle.

[0066] For the other part of the samples, after being dispersed by the sampling grids 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 inside of the double cone 1151. By the method of cone dispersion through free fall, different sample grains in the samples are evenly distributed to achieve the purpose of uniform mixing.

[0067] Next, when the third hopper 113 rotates 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 sample located in the fourth hopper 114 begins to flow into the third hopper 113. These samples will be dispersed again through the back of the sampling grids 1154 and then evenly enter the second hopper 112. Finally, they will flow into the first hopper 111 to complete a circulation cycle in the other direction.

[0068] 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 circulation of the samples. This design greatly improves the efficiency and stability of the raw grain processing system and provides a reliable guarantee for the subsequent processing and detection work.

[0069] It should be noted that generally there are multiple sample dividing grids 1154, and the multiple sample dividing grids 1154 are arranged at intervals in sequence along the circumferential direction of the double cone 1151. 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 flowing process, thereby improving the mixing uniformity and efficiency. This design is particularly useful when highly efficient mixing of raw grain samples of different types or characteristics is required, and can meet the requirements of different processes and products.

[0070] In a specific embodiment, the side wall of the double cone 1151 cooperating with the hopper forms 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 freely falls and is evenly dispersed on the double cone 1151, it enters the first material dividing grid or the second material dividing grid. Subsequently, a part of the sample freely falls along the outside of the double cone 1151 through the second material dividing grid, and another part of the sample enters the inside of the double cone 1151 and falls through the first material dividing grid. The two parts of the sample are mixed, and by the way of freely falling and being dispersed by the cone, different sample grains in the sample are evenly distributed to achieve the purpose of uniform mixing.

[0071] In some embodiments, as Figure 1 and Figure 2 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.

[0072] 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 samples 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 samples according to the actual production requirements.

[0073] 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.

[0074] In addition, the introduction of the first valve 116 also provides convenience for 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, thereby avoiding unnecessary influence on the entire raw grain sample mixing device.

[0075] In another embodiment, as Figure 1 andFigure 2 As 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 be 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 samples. For example, during the mixing process, the operator can close or open these valves as needed to adjust the communication state between different hoppers, so as to achieve more precise mixing control. In addition, this design also helps to prevent the leakage and waste of the raw grain samples during the mixing process. When the sample in a certain hopper reaches the preset mixing degree, the operator can close the corresponding valve to prevent the sample from continuing to enter the next hopper, thus ensuring the stability and consistency of the mixing effect.

[0076] Specifically, when the second driving mechanism 14 controls the second hopper 112 to rotate to the directly above of 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, after the sample enters the first hopper 111, the first driving mechanism 13 controls the cover plate 12 to move to the first position to block the material port.

[0077] Then, the first valve 116 and the second valve 117 are opened. In addition, the sample located in the first hopper 111 begins 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. And another part of the samples, after being dispersed by the sample dividing grid 1154, 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.

[0078] Next, close the first valve 116 and the second valve 117, and use the second driving mechanism 14 to control the rotation of the mixing bin 11. 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, open the first valve 116 and the second valve 117, and the raw grain samples in the fourth hopper 114 will 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 the circulation in another direction. Finally, repeat the above operations until the pre-designed number of mixing times is reached, then lower the first hopper 111, open the cover plate 12, and place the samples into the raw grain sample reduction device 3 to complete the operation.

[0079] Based on the above embodiments, in some embodiments, such 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 a first position and a second position.

[0080] In this embodiment, the first driving mechanism 13 uses the 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.

[0081] For example, when the cylinder 131 is in a contracted state, the cover plate 12 is in the closed position, completely covering the material opening of the first hopper 111 to prevent the raw grain samples from entering the mixing bin from the first hopper 111.

[0082] When the cylinder 131 is in an extended state, the cover plate 12 is moved away from the material opening of the first hopper 111, exposing the material opening and allowing the raw grain samples to enter the mixing bin from the first hopper 111 for mixing.

[0083] 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.

[0084] Similarly, based on the above embodiments, in some embodiments, such as Figure 1 and Figure 2As 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 for driving 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 meet 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 samples between the hoppers, improving the mixing uniformity and efficiency. The use of the first motor 141 ensures the stability and reliability of the rotation process, providing strong power support for the mixing process.

[0085] 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, and the other end of the bracket 142 is connected to the mixing bin 11. 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.

[0086] Specifically, when it is necessary to add raw grain samples to the mixing bin 11, the cylinder of the first driving mechanism 13 extends, pushing the cover plate 12 away from the feed opening of the first hopper 111 to expose the feed opening. When it is necessary to stop adding raw grain samples, the cylinder of the first driving mechanism 13 contracts, pulling the cover plate 12 back to the closed position to prevent the raw grain samples 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 samples are 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 samples in the mixing bin are fully mixed.

[0087] In some embodiments, as Figures 5 to 9 shown, the sub-material chambers are respectively the first sub-material chamber, the second sub-material chamber, the third sub-material chamber, and the fourth sub-material chamber. The first sub-material chamber and the second sub-material chamber are communicated with their corresponding two discharge ports 321, and the third sub-material chamber and the fourth sub-material chamber are communicated with their corresponding five discharge ports 321.

[0088] Specifically, among these four sub-material cavities, the design principles of the first sub-material cavity and the second sub-material cavity are similar, and they are both directly connected to their corresponding two specific discharge ports 321. When the material distribution wheel 32 rotates in the material cavity, these sub-material cavities will receive the raw grain samples flowing out of the second cavity through their respective discharge ports. Since each sub-material cavity is connected to two discharge ports, the amount of samples they receive is relatively small, but it is sufficient to meet specific experimental or production requirements.

[0089] The third sub-material cavity and the fourth sub-material cavity are connected to the corresponding five discharge ports 321. When the material distribution wheel 32 rotates, the third sub-material cavity and the fourth sub-material cavity will simultaneously receive the raw grain samples from the corresponding five discharge ports. Therefore, the amount of samples they receive will be more than that of other sub-material cavities. This design enables the third sub-material cavity and the fourth sub-material cavity to store more reduced raw grain samples.

[0090] Through this design of multiple sub-material cavities, the raw grain sample reduction device 3 can simultaneously achieve multiple reductions in different ratios (achieving a reduction ratio of 2:2:5:5), improving the flexibility and practicality of the equipment. At the same time, since each sub-material cavity is directly connected to its corresponding discharge port, the reduction process is more accurate and reliable, ensuring the accuracy of experimental and production results.

[0091] In some embodiments, as Figures 5 to 9 shown, the material distribution bin 31 includes: a first housing 311, a second housing 312, and a first discharge partition, a second discharge partition, and a third discharge partition that are sequentially arranged at intervals along the circumferential direction of the material distribution wheel 32; the first housing 311 and the second housing 312 are butt-jointed to form a material cavity. The first housing 311 and the first discharge partition form the first sub-material cavity, the first discharge partition and the second discharge partition form the second sub-material cavity in the material cavity, the second discharge partition and the third discharge partition form the third sub-material cavity in the material cavity, and the third discharge partition and the second housing 312 form the fourth sub-material cavity in the material cavity.

[0092] In this embodiment, the first housing 311 and the second housing 312 are docked with each other, and the two are closely fitted to jointly form a closed material cavity. This material cavity is the area for storing and preparing the distribution of 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. Finally, the space between the third discharge partition and the second housing 312 forms a fourth sub-material cavity in the material cavity. This sub-material cavity is used to receive and store the fourth part of the raw grain samples distributed from the material cavity.

[0093] To facilitate the export of 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, and a fourth discharge pipe 37. 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.

[0094] In this embodiment, the first discharge pipe 34 is communicated with the first sub-material cavity for exporting the raw grain samples in the first sub-material cavity. The second discharge pipe 35 is communicated with the second sub-material cavity for exporting the raw grain samples in the second sub-material cavity. The third discharge pipe 36 is communicated with the third sub-material cavity for exporting the raw grain samples in the third sub-material cavity. The fourth discharge pipe 37 is communicated with the fourth sub-material cavity for exporting the raw grain samples in the fourth sub-material cavity. The first sub-material cavity and the second sub-material cavity receive the samples from two discharge ports 321, and the third sub-material cavity and the fourth sub-material cavity receive the samples from five discharge ports 321, so as to achieve a reduction ratio of 2:2:5:5.

[0095] 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, and the fourth discharge pipe 37 away from the material cavity extend in different directions.

[0096] This design enables each discharge pipe to independently export the raw grain samples in its corresponding sub-material cavity without interfering with or affecting each other. For example, when it is necessary to export the samples in multiple sub-material cavities simultaneously, the staff can easily operate through different discharge pipes without worrying about sample confusion or cross-contamination problems.

[0097] In addition, the discharging pipes extending in different directions also facilitate the layout and installation of the equipment. In practical applications, according to specific site conditions and operation requirements, the discharging pipes can be flexibly placed in appropriate positions to facilitate the operation and observation by the staff.

[0098] In some embodiments, the raw grain sample reduction device 3 further includes: a locking shaft 39. Connecting seats 313 are provided on the first housing 311 and the second housing 312, and the locking shaft 39 is rotatably inserted through the connecting seats 313 and an external structure.

[0099] Specifically, the locking shaft 39 is rotatably inserted through the connecting seats 313 and an external structure. Such a design allows the user to lock or unlock the first housing 311 and the second housing 312 by operating the locking shaft 39. At one end of the locking shaft 39, there is a handle for easy gripping. The user can easily lock or unlock the housing by gently turning the handle.

[0100] When the first housing 311 and the second housing 312 are locked, their connection will become very firm, which can not only prevent the raw grain sample in the material chamber from leaking, but also ensure a stable operating environment for the 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.

[0101] 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 material distribution bin 31, and the fifth hopper 314 is communicated with the feed port through the feed pipe 315. The design of the fifth hopper 314 enables the user to conveniently pour the raw grain sample into it, preparing for the subsequent reduction operation. To smoothly introduce the raw grain sample in the fifth hopper 314 into the material chamber of the material distribution bin, the device is also equipped with a feed pipe 315. One end of the feed pipe 315 is communicated with the bottom of the fifth hopper 314, and the other end is connected to the feed port of the material distribution bin 31. When the raw grain sample in the fifth hopper 314 accumulates to a certain extent, they will naturally flow into the material chamber of the material distribution bin through the feed pipe 315, and then be reduced by the material distribution wheel 32 according to a predetermined ratio. The design of the fifth hopper 314 and the feed pipe 315 not only simplifies the introduction process of the raw grain sample, improves work efficiency, but also ensures the continuity and stability of the reduction operation.

[0102] Among them, a third valve 316 is provided on the feed pipe 315. The precise control function of the third valve 316 enables users to adjust the flow rate and entry speed of the sample at any time according to needs. Such adjustment not only helps to ensure the stability and continuity of the riffling process, but also contributes to improving the accuracy and consistency of the riffling results. By precisely controlling the opening degree of the third valve 316, users can ensure that the raw grain sample flows into the dividing bin at an appropriate speed, thereby avoiding the accumulation or overflow of the sample in the material cavity and ensuring the smooth progress of the riffling process. Secondly, the introduction of the third valve 316 also enhances the safety of the raw grain sample riffling device 3. During the riffling 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 dividing bin after the equipment stops running, ensuring the smooth progress of the cleaning and maintenance work of the riffling device.

[0103] In some embodiments, such as Figure 7 and Figure 8 shown, a second cavity is formed inside 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. Axial discharge ports refer to the discharge ports distributed along the axis direction of the dividing wheel 32, and they are usually located on both sides of the dividing wheel to ensure that when the dividing wheel rotates, the raw grain sample can flow out along the axial direction. The radial discharge ports refer to the discharge ports distributed along the radius direction of the dividing wheel 32, and they are usually evenly distributed on the side wall of the dividing wheel, so that the raw grain sample can flow out along the radial direction when the dividing wheel rotates. This design enables the dividing wheel 32 to precisely control the discharge position and flow rate of the raw grain sample during rotation, thereby realizing the precise riffling of the raw grain sample. At the same time, by adjusting the number, size and distribution position of the discharge ports 321, the riffling effect can be further optimized to meet the requirements of different experiments and productions.

[0104] In this embodiment, as Figure 8 shown, five discharge ports 321 are provided on one end face of the dividing wheel 32 in the axial direction, which communicate with the fourth sub-hopper. Nine discharge ports 321 are provided in the radial direction of the dividing wheel 32, which communicate with the second sub-hopper, the third sub-hopper and the fourth sub-hopper respectively. Among them, the first sub-hopper and the second sub-hopper communicate with their corresponding two discharge ports 321, and the third sub-hopper communicates with its corresponding five discharge ports 321.

[0105] When considering the actual use requirements of the raw grain sample reduction device, the design of the fifth hopper 314 is also optimized accordingly. In order to enhance the flexibility and practicality of the device, a movable cover plate can be added to the fifth hopper 314. The cover plate is in transmission connection with the second driving mechanism, and can be moved between a first position that blocks the entrance of the fifth hopper 314 and a second position that exposes the entrance of the fifth hopper 314 through the drive of the second driving mechanism.

[0106] When the cover is in the first position, it completely blocks the entrance of the fifth hopper 314, preventing the raw grain sample from overflowing from the fifth hopper or being contaminated by the outside world. This design is particularly useful when there is no need to add samples to the fifth hopper, as it ensures that the inside of the fifth hopper is clean and dry, preventing the sample from getting damp or deteriorating.

[0107] When it is necessary to add a raw grain sample to the fifth hopper, the second drive mechanism drives the cover plate to move from the first position to the second position, exposing the entrance of the fifth hopper 314. At this time, the user can conveniently pour the sample into the fifth hopper and prepare for the reduction operation. After adding the sample, the second drive mechanism drives the cover plate back to the first position again to cover the entrance of the fifth hopper again.

[0108] This movable cover design not only improves the flexibility and practicality of the raw grain sample reduction device, but also enhances the safety and reliability of the equipment. By controlling the opening and closing of the cover, users can more flexibly control the sample addition and reduction process to ensure the accuracy and consistency of the reduction results. At the same time, the shielding function of the cover can also prevent external contamination and accidents, protecting the safety of the equipment and operators.

[0109] In some embodiments, Figure 5 and Figure 6As 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.
