Description

Technical Field

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

[0002] In the field of grain quality inspection, the mixing uniformity of raw grain samples plays a vital role. It is the key to ensure that the inspection data is accurate and representative. However, the current market lacks a device specifically designed for mixing raw grain samples uniformly, which has become a bottleneck restricting inspection efficiency and accuracy. Most existing mixing equipment focuses on the processing of grain powder, and its structure and operation method are not suitable for the characteristics of raw grain samples.

[0003] At present, in order to ensure the representativeness of raw grain samples, inspectors have to rely on the traditional double-cone bidirectional inward flow mixer for manual mixing of raw grain samples. However, this traditional method has many limitations: first, since the mixing process is almost entirely dependent on manual operation, it is difficult to achieve automation and intelligent control, which not only leads to unstable mixing effects, but is also easily interfered by human factors; second, manual mixing of raw grain samples consumes a lot of physical strength and energy of inspectors, especially when dealing with large batches of samples, the labor intensity increases dramatically, which in turn affects work efficiency; third, since the mixing process is time-consuming and it is necessary to wait for the mixing to be uniform before subsequent inspection, the efficiency of the entire inspection process is severely restricted; finally, the differences in techniques and strength during manual operation may lead to uneven mixing, which directly affects the accuracy of the inspection results.

[0004] Therefore, there is an urgent need to develop a device that can efficiently and uniformly mix raw grain samples, which has urgent market demand and broad application prospects. Utility Model Content

[0041] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0042] In the description of the embodiments of the present invention, the terms “first” and “second” are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0043] In the description of the embodiments of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. 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.

[0044] 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.

[0045] The utility model provides a double-conical bidirectional inward flow mixing device for raw grain samples, such as Figures 1 to 5 As shown, the raw grain sample double-conical bidirectional inward flow mixing device 2 comprises: a mixing bin 21, a first door plate 22, a second door plate 23, a first driving mechanism 24 and a supporting structure. The mixing bin 21 is formed with a cavity for loading the raw grain sample, and the two ends of the mixing bin 21 are respectively provided with a first material port and a second material port connected to the cavity; the first driving mechanism 24 is transmission-connected with the first door plate 22 and the second door plate 23, the first door plate 22 is arranged at the first material port, and the second door plate 23 is arranged at the second material port, and the first driving mechanism 24 is used to drive the first door plate 22 to cover or expose the first material port and drive the second door plate 23 to cover or expose the second material port; the mixing bin 21 is rotatably arranged on the supporting structure.

[0046] In this embodiment, the mixing bin 21 is the main structure of the device and has a cavity for loading raw grain samples. In order to ensure convenient loading and removal of samples, the first material port and the second material port connected to the cavity are respectively provided at both ends of the mixing bin 21. The design of these two material ports makes the addition and removal of raw grain samples very convenient. The first door panel 22 and the second door panel 23 are used to control the opening and closing of the first material port and the second material port. The first door panel 22 and the second door panel 23 are driven by the first driving mechanism 24. The first driving mechanism 24 can accurately control the movement of the first door panel 22 and the second door panel 23, so that the first door panel 22 can cover or expose the first material port, and the second door panel 23 can cover or expose the second material port.

[0047] During operation, the first door panel 22 is opened to expose the first material port. The raw grain sample to be mixed is poured into the cavity of the mixing bin 21 through the first material port. Then the first door panel 22 is closed to ensure the closure of the mixing bin 21. The mixing bin 21 is driven to start rotating. During the rotation of the mixing bin 21, the raw grain samples begin to collide, rub and mix with each other in the cavity. The rotation speed and duration of the mixing bin 21 can be adjusted as needed to achieve the best mixing effect. When the predetermined mixing time is reached or the sample is observed to be evenly mixed, the mixing bin 21 stops rotating. The mixing uniformity of the sample can be detected through an observation window or a sampler to ensure that the requirements are met. Finally, the second door panel 23 (or the first door panel 22) is opened to expose the second material port (or the first material port). Take out the mixed raw grain sample from the second material port. Close the second door panel 23 and prepare for the next mixing operation.

[0048] The double-conical bidirectional inward flow mixing device for raw grain samples provided by the utility model supports the mixing bin through a supporting structure, which can ensure that the raw grain samples are stirred and mixed in all directions in the cavity, thereby achieving uniform mixing and avoiding the problem of local uneven mixing that may occur in traditional mixing methods. The first drive mechanism is connected to the first door panel and the second door panel in a transmission manner, and can conveniently control the opening and closing of the first door panel and the second door panel. When it is necessary to add or remove the raw grain sample, the first drive mechanism can quickly open and close the first material port and the second material port, thereby improving the convenience and efficiency of operation.

[0049] It should be noted that, in order to meet different usage requirements, the raw grain sample double-conical bidirectional inward flow mixing device 2 can also be equipped with the following extended functions: for example, a weighing sensor is set in the mixing bin 21 to monitor the weight change of the raw grain sample in the mixing bin 21 in real time, and provide data support for the control of the mixing ratio. A temperature sensor and a heater / refrigerator are set inside the mixing bin 21 to ensure that the raw grain sample maintains a constant temperature during the mixing process. Components such as a cleaning nozzle and a water pump are set inside the mixing bin 21 to realize the automatic cleaning function of the equipment and reduce the labor intensity of manual cleaning.

[0050] In some embodiments, Figures 1 to 5 As shown, the double-conical bidirectional inward flow mixing device 2 for raw grain samples also includes: a second driving mechanism 25. The second driving mechanism 25 is connected to the mixing bin 21 in transmission, and the second driving mechanism 25 is used to drive the mixing bin 21 to rotate so that the raw grain samples are mixed evenly in the cavity. The second driving mechanism 25 is connected to the mixing bin 21 in transmission, and its function is to drive the mixing bin 21 to rotate. When the mixing bin 21 rotates, the raw grain samples will collide and rub against each other in the cavity due to the centrifugal force, thereby achieving a uniform mixing effect. This method of rotational mixing is more efficient than traditional static mixing, and can ensure that the raw grain samples achieve an ideal mixing effect in a short time.

[0051] During operation, the first door panel 22 is opened to expose the first material port. The raw grain sample to be mixed is poured into the cavity of the mixing bin 21 through the first material port. Then the first door panel 22 is closed to ensure the closedness of the mixing bin 21. The second drive mechanism 25 is started to drive the mixing bin 21 to start rotating on the support structure. During the rotation of the mixing bin 21, the raw grain samples begin to collide, rub and mix with each other in the cavity. The rotation speed and duration of the mixing bin 21 can be adjusted as needed to achieve the best mixing effect. When the predetermined mixing time is reached or the sample is observed to be mixed evenly, the second drive mechanism 25 is stopped to stop the rotation of the mixing bin 21. The mixing uniformity of the sample can be detected through the observation window or the sampler to ensure that the requirements are met. Finally, the second door panel 23 is opened to expose the second material port. Take out the mixed raw grain sample from the second material port. Close the second door panel 23 to prepare for the next mixing operation.

[0052] In some embodiments, Figure 1 As shown, the mixing bin 21 includes: a first hopper 211, a second hopper 212, a third hopper 213 and a fourth hopper 214 which are connected in sequence. A cavity is formed in the first hopper 211, the second hopper 212, the third hopper 213 and the fourth hopper 214, the first hopper 211 is provided with a first material opening, and the fourth hopper 214 is provided with a second material opening; the second driving mechanism 25 is connected to at least one of the first hopper 211, the second hopper 212, the third hopper 213 and the fourth hopper 214.

[0053] In this embodiment, since the mixing bin 21 is divided into a plurality of hoppers, the raw grain samples in each hopper will undergo multiple mixing and exchange during rotation, thereby achieving a more uniform and efficient mixing effect. The segmented design allows the operator to more conveniently observe the mixing conditions in each hopper, thereby making adjustments and controls according to the actual conditions. At the same time, sensors and other devices may also be provided on each hopper to achieve automatic monitoring and control.

[0054] In terms of driving, the second driving mechanism 25 is connected to at least one of the first hopper 211, the second hopper 212, the third hopper 213 and the fourth hopper 214. This connection mode can be flexibly adjusted according to specific mixing requirements and equipment design. For example, the second driving mechanism 25 can be connected to the second hopper 212, and the rotation of the second hopper 212 can be driven to drive the rotation of the entire mixing bin; or the second driving mechanism 25 can be connected to multiple hoppers to achieve more complex mixing actions and effects.

[0055] In some embodiments, Figures 1 to 5As shown, the mixing bin 21 further includes a dispersing mechanism 215. The dispersing mechanism 215 is disposed in a cavity corresponding to the second hopper 212 and / or the third hopper 213, and the dispersing mechanism 215 is used to disperse the raw grain sample entering the fourth hopper 214 from the first hopper 211 or the raw grain sample entering the first hopper 211 from the fourth hopper 214 during the rotation of the mixing bin 21.

[0056] Specifically, when the mixing bin 21 starts to rotate, the raw grain sample will flow between the first hopper 211, the second hopper 212, the third hopper 213 and the fourth hopper 214 under the action of gravity and centrifugal force. The dispersion mechanism 215 can further break up and disperse these flowing samples, thereby preventing the samples from forming lumps or agglomerations during the flow process, and ensuring that the samples can be evenly mixed in the entire mixing bin. The specific design of the dispersion mechanism 215 can be adjusted according to actual needs, for example, structures such as rotating blades, stirring rods or vibrators can be used. These structures can generate appropriate shear force or impact force when the mixing bin rotates, and effectively disperse the samples. By introducing the dispersion mechanism 215, this raw grain sample double-conical two-way internal flow mixing device 2 can further improve the mixing effect and ensure that the raw grain sample is more evenly and thoroughly mixed in the mixing bin. At the same time, the design also increases the adaptability and flexibility of the equipment, and can handle raw grain samples of different types and characteristics.

[0057] In some embodiments, Figures 1 to 6 As shown, the dispersing mechanism 215 comprises: a double cone 2151, one end of the double cone 2151 is located at the second hopper 212 and is provided with a first dispersing port, a first dispersing port cover plate 2152 is provided at the first dispersing port, a sample dividing grid 2153 is formed at the gap between the double cone 2151 and the second hopper 212 and / or the third hopper 213, and both sides of the sample dividing grid 2153 facing the first hopper 211 and the fourth hopper 214 are provided with an opening connected to the inside of the double cone 2151; The other end is located at the third hopper 213 and is provided with a second dispersion port, and a second dispersion port cover 2154 is provided at the second dispersion port; when the second hopper 212 rotates to above the third hopper 213, the first dispersion port cover 2152 blocks the first dispersion port, and the second dispersion port cover 2154 exposes the second dispersion port; when the third hopper 213 rotates to above the second hopper 212, the first dispersion port cover 2152 exposes the first dispersion port, and the second dispersion port cover 2154 blocks the second dispersion port.

[0058] Specifically, when the second hopper 212 rotates to the top of the third hopper 213, the first dispersion port cover plate 2152 and the second dispersion port cover plate 2154 will automatically adjust the opening and closing of the first dispersion port and the second dispersion port. The first dispersion port cover plate 2152 blocks the first dispersion port, and the second dispersion port cover plate 2154 exposes the second dispersion port. At this time, the raw grain sample located in the first hopper 211 begins to flow into the second hopper 212. As the samples continue to enter, they will encounter the sample grid 2153. The ingenious design of the sample grid 2153 allows the samples to be evenly dispersed during the inflow process. The dispersed samples will experience two main flow paths: a part of the samples directly enters the interior of the double cone 2151 through the open mouth of the sample grid 2153, and then is led out to the third hopper 213 through the second dispersion port. These samples will eventually flow into the fourth hopper 214, completing a circulation cycle. The other part of the samples, after being dispersed by the sample grid 2153, will directly fall into the third hopper 213. This part of the sample will also eventually enter the fourth hopper 214, but their flow path is more direct and does not need to pass through the inside of the double cone 2151. The cone dispersion method through free fall makes the different particles in the sample evenly distributed to achieve the purpose of uniform mixing.

[0059] Next, when the third hopper 213 rotates to the top of the second hopper 212, the first dispersion port cover plate 2152 and the second dispersion port cover plate 2154 will be adjusted again, the first dispersion port cover plate 2152 exposes the first dispersion port, and the second dispersion port cover plate 2154 covers the second dispersion port. At this time, the raw grain sample located in the fourth hopper 214 begins to flow into the third hopper 213. As the samples continue to enter, they will encounter the sample grid 2153. The sample grid 2153 allows the samples to be evenly dispersed during the inflow process. The dispersed samples will experience two main flow paths: a part of the samples directly enters the interior of the double cone 2151 through the open mouth of the sample grid 2153, and then is led out to the second hopper 212 through the first dispersion port. These samples will eventually flow into the first hopper 211, completing a circulation cycle. Another part of the samples, after being dispersed by the sample grid 2153, will directly fall into the second hopper 212. This part of the samples will also eventually enter the first hopper 211.

[0060] It should be noted that there are generally multiple sample grids 2153, and the multiple sample grids 2153 are sequentially spaced along the circumference of the double cone 2151, and the side walls of adjacent sample grids 2153 form hollow sample grids. The design of multiple sample grids 2153 allows the raw grain sample to be dispersed more times during the flow process, thereby improving the uniformity and efficiency of mixing. This design is particularly useful when raw grain samples of different types or characteristics need to be efficiently mixed, and can meet the needs of different processes and products.

[0061] In a specific embodiment, the side wall of the double cone 2151 cooperates with the hopper to form a first sampling grid, a second sampling grid and a third sampling grid, the first sampling grid is provided with an opening connected to the inside of the double cone 2151 on the side facing the first hopper 211, and the second sampling grid is a hollow sampling grid. The third sampling grid is arranged on the back of the first sampling grid, and is provided with an opening connected to the inside of the double cone 2151 on the side facing the fourth hopper 214.

[0062] Thus, when the second hopper 212 rotates to the top of the third hopper 213, the material on one side is evenly dispersed by free falling to the double cone 2151, and then enters the first or second dividing grid, and then a part of the sample freely falls along the outside of the double cone 2151 through the second dividing grid, and the other part of the sample passes through the first dividing grid and enters the inside of the double cone 2151, and the two parts of the sample are mixed and enter the fourth hopper 214, and the cone dispersion method of free falling is used to evenly distribute different particles in the sample to achieve the purpose of uniform mixing. When the third hopper 213 rotates to the top of the second hopper 212, the material on the other side is evenly dispersed by free falling to the double cone 2151, and then enters the second or third dividing grid, and then a part of the sample freely falls along the outside of the double cone 2151 through the second dividing grid, and the other part of the sample passes through the third dividing grid and enters the inside of the double cone 2151, and the two parts of the sample are mixed and enter the first hopper 211.

[0063] In some embodiments, Figure 1 and Figure 2 As shown, the mixing bin 21 further includes a first valve 216. The first valve 216 is disposed between the first hopper 211 and the second hopper 212. The first hopper 211 is connected to the second hopper 212 through the first valve 216.

[0064] In this embodiment, the main function of the first valve 216 is to control whether the first hopper 211 and the second hopper 212 are connected, and to control the flow rate and speed of the raw grain sample from the first hopper 211 into the second hopper 212. By accurately adjusting the opening of the first valve 216, the operator can flexibly control the mixing speed and mixing ratio of the raw grain sample according to actual production needs.

[0065] This design not only improves the flexibility and adaptability of the mixing bin 21, but also makes the entire mixing process more controllable and stable. When it is necessary to accurately control the mixing effect or perform special process treatment, the role of the first valve 216 is particularly important.

[0066] In addition, the introduction of the first valve 216 also facilitates the maintenance and cleaning of the mixing bin 21. When a hopper needs to be cleaned or repaired, the hopper that needs to be cleaned or repaired can be isolated from other hoppers by closing the corresponding valve, thereby avoiding unnecessary impact on the entire raw grain sample double-conical bidirectional inflow mixing device 2.

[0067] In another embodiment, if Figure 1 and Figure 2 As shown, the mixing bin 21 also includes: a first valve 216 and a second valve 217. The first valve 216 and the second valve 217 can be closed by a solenoid valve or a rack-driven sealing plate. The first valve 216 is arranged between the first hopper 211 and the second hopper 212. The first hopper 211 is connected to the second hopper 212 through the first valve 216. The second valve 217 is arranged between the third hopper 213 and the fourth hopper 214, and the third hopper 213 is connected to the fourth hopper 214 through the second valve 217. The addition of the first valve 216 and the second valve 217 provides more flexibility and controllability for the mixing of raw grain samples. For example, during the mixing process, the operator can close or open these valves as needed to adjust the connection state between different hoppers, thereby achieving more refined mixing control. In addition, this design also helps to prevent leakage and waste of raw grain samples during the mixing process. When the sample in a hopper reaches a preset mixing degree, the operator can prevent the sample from continuing to enter the next hopper by closing the corresponding valve, thereby ensuring the stability and consistency of the mixing effect.

[0068] Specifically, when the second hopper 212 rotates to the top of the third hopper 213, the first dispersion port cover plate 2152 and the second dispersion port cover plate 2154 will automatically adjust the opening and closing of the first dispersion port and the second dispersion port. The first dispersion port cover plate 2152 blocks the first dispersion port, and the second dispersion port cover plate 2154 exposes the second dispersion port.

[0069] If a loading instruction is received, the first driving mechanism 24 drives the first door panel 22 to quickly open the first material port. After the sample information is identified by scanning the code, after the sample enters the first hopper 211, the first driving mechanism 24 drives the first door panel 22 to close the first material port.

[0070] Then, the first valve 216 and the second valve 217 are opened, and the raw grain sample in the first hopper 211 begins to flow into the second hopper 212. As the samples continue to enter, they will encounter the sample grid 2153. The ingenious design of the sample grid 2153 allows the samples to be evenly dispersed during the inflow process. The dispersed samples will experience two main flow paths: a part of the samples directly enters the interior of the double cone 2151 through the opening of the sample grid 2153, and then is led out to the third hopper 213 through the second dispersion port. These samples will eventually flow into the fourth hopper 214, completing a circulation cycle. The other part of the samples, after being dispersed by the sample grid 2153, will directly fall into the third hopper 213. This part of the samples will also eventually enter the fourth hopper 214, but their flow path is more direct and does not need to pass through the interior of the double cone 2151. The cone dispersion method of free fall allows the different particles in the sample to be evenly distributed to achieve the purpose of uniform mixing.

[0071] Next, the first valve 216 and the second valve 217 are closed, and the second driving mechanism 25 is used to control the mixing bin 21 to rotate 180 degrees. When the third hopper 213 rotates to the top of the second hopper 212, the first dispersion port cover plate 2152 and the second dispersion port cover plate 2154 will be adjusted again, the first dispersion port cover plate 2152 exposes the first dispersion port, and the second dispersion port cover plate 2154 covers the second dispersion port. At this time, the first valve 216 and the second valve 217 are opened, and the raw grain sample located in the fourth hopper 214 begins to flow into the third hopper 213. As the samples continue to enter, they will encounter the sample grid 2153. The sample grid 2153 allows the samples to be evenly dispersed during the inflow process. The dispersed samples will experience two main flow paths: a part of the samples directly enter the interior of the double cone 2151 through the open mouth of the sample grid 2153, and then be led out to the second hopper 212 through the first dispersion port. These samples will eventually flow into the first hopper 211, completing a circulation cycle. The other part of the sample, after being dispersed by the sample dividing grid 2153, will directly fall into the second hopper 212. This part of the sample will also eventually enter the first hopper 211. Finally, after repeating the above operation to the pre-designed mixing times, the first hopper 211 or the fourth hopper 214 is downward, and the sample is placed in the raw grain sample reduction device to complete the operation.

[0072] In some embodiments, Figures 1 to 5As shown, the first driving mechanism 24 includes: a first motor, a second motor, a first rotating disk 241 and a second rotating disk 242; the first door panel 22 and the second door panel 23 each include a plurality of fan plates. The shape of the fan plates can be designed according to the shape and size of the material opening to achieve a better sealing effect. The first motor is connected to the plurality of fan plates of the first door panel 22 through the first rotating disk 241 to cover or expose the first material opening by driving the plurality of fan plates of the first door panel 22. The second motor is connected to the plurality of fan plates of the second door panel 23 through the second rotating disk 242 to cover or expose the second material opening by driving the plurality of fan plates of the second door panel 23.

[0073] Specifically, a plurality of first connecting rods are provided on the first rotating disk 241, and each first connecting rod is connected to a fan plate on the first door panel 22. When the first rotating disk 241 rotates, each first connecting rod drives the corresponding fan plate to move, so as to cover or expose the first material opening. Similarly, a plurality of second connecting rods are provided on the second rotating disk 242, and each second connecting rod is connected to a fan plate on the second door panel 23. When the second rotating disk 242 rotates, each second connecting rod drives the corresponding fan plate to move, so as to cover or expose the second material opening. At the same time, a limit switch can be set on the rotation path of the first rotating disk 241 and the second rotating disk 242 to prevent the first rotating disk 241 and the second rotating disk 242 from excessive rotation or damage.

[0074] In some embodiments, Figures 1 to 6 As shown, the second driving mechanism 25 includes: a third motor; the rotating end of the third motor is connected to the mixing bin 21, and is used to drive the mixing bin 21 to rotate. The second driving mechanism 25 is the core driving component of the entire raw grain sample double-conical bidirectional inflow mixing device 2, and is responsible for driving the mixing bin 21 to rotate to achieve uniform mixing of the raw grain sample. Its design needs to ensure sufficient driving force, stability and durability to meet the mixing requirements of raw grain samples of different types and quantities. The third motor usually adopts an AC motor or a DC motor, and the specific type can be selected according to the actual operating environment and control requirements. For example, for scenarios where precise control of speed and position is required, a servo motor or a stepper motor can be selected. The power of the third motor should be determined according to the size, weight and required maximum speed of the mixing bin 21. Too little power may lead to insufficient driving force, while too much power may increase energy consumption and cost. The speed range of the third motor should meet the rotation speed requirements of the mixing bin 21. For different raw grain samples and mixing requirements, the speed may need to be adjusted to achieve the best mixing effect.

[0075] In this embodiment, Figure 5As shown, the supporting structure includes: a first rotating shaft 251, a second rotating shaft 252, a first bracket 253 and a second bracket 254; the first rotating shaft 251 and the second rotating shaft 252 are coaxially arranged, the first rotating shaft 251 is rotatably arranged on the first bracket 253 and connected to one side of the mixing bin 21, the second rotating shaft 252 is rotatably arranged on the second bracket 254 and connected to the other side of the mixing bin 21, and at least one of the first rotating shaft 251 and the second rotating shaft 252 is connected to the third motor.

[0076] Specifically, when the third motor is started, its rotating end drives the rotating shaft (the first rotating shaft 251 or the second rotating shaft 252) connected thereto to rotate through the transmission device. Since the two rotating shafts are coaxially arranged and are both connected to the mixing bin 21, the mixing bin 21 will also rotate under the drive of the rotating shaft. During the rotation process, the first bracket 253 and the second bracket 254 provide stable support for the rotating shaft, ensuring that the rotation movement of the mixing bin 21 is smooth and reliable.
