Description

Technical Field

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

[0002] In the field of grain quality inspection, the mixing uniformity of raw grain samples is crucial to ensure the accuracy and representativeness of the inspection results. However, there is a lack of mixing devices specifically designed for mixing raw grain samples uniformly on the market. Most mixing equipment is mainly designed for grain powder, and its structure and operation method are not suitable for raw grain samples.

[0003] In the existing inspection process, in order to obtain representative raw grain samples, inspectors usually use grain sample dividers for mixing. However, this operation method mainly relies on manual implementation, and there are the following problems: Since the mixing process mainly relies on manual operation, it is impossible to achieve automation and intelligent control, resulting in unstable mixing effect and easy to be affected by human factors. Manual mixing of raw grain samples requires inspectors to invest a lot of physical strength and energy, especially when dealing with a large number of samples, the labor intensity increases significantly, which may lead to a decrease in work efficiency. 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 limited. During the manual mixing process, due to differences in operating techniques and strength, uneven mixing may occur, thus affecting 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

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] The utility model provides a double-conical one-way inward flow mixing device for grain particles, such as Figure 1 As shown, the grain particle double-conical unidirectional inward flow mixing device 1 comprises: 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 cavity for loading raw grain samples, and the mixing bin 11 is provided with a material port connected to the cavity; the first driving mechanism 13 is connected to the cover plate 12 in a transmission manner, and the first driving mechanism 13 is used to drive the cover plate 12 to move between a first position for shielding the material port and a second position for exposing the material port. The second driving mechanism 14 is connected to the mixing bin 11 in a transmission manner, and the second driving mechanism 14 is used to drive the mixing bin 11 to rotate, so that the raw grain samples are mixed evenly in the cavity.

[0039] 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 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.

[0040] The whole grain particle double cone unidirectional inward flow mixer can also be equipped with an intelligent control system, which can realize accurate control of the first drive mechanism 13 and the second drive 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.

[0041] The double-conical one-way inward flow mixing device for grain particles provided by the embodiment of the utility model drives the mixing bin 11 to rotate through the second drive mechanism 14, which can ensure that the raw grain sample is 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 13 is connected to the cover plate 12 in a transmission manner, and can conveniently control the opening and closing of the cover plate 12. When it is necessary to add or remove the raw grain sample, the first drive mechanism 13 can quickly move the cover plate from a position blocking the material opening to a position exposing the material opening, greatly improving the convenience and efficiency of operation.

[0042] It should be noted that in order to meet different usage requirements, the grain particle double-conical unidirectional inward flow 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.

[0043] 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 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.

[0044] In this embodiment, since the mixing bin 11 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 actual conditions. At the same time, sensors and other devices may also be provided on each hopper to achieve automatic monitoring and control.

[0045] 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 mode 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 can be 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.

[0046] In some embodiments, Figures 1 to 3 As shown, the mixing bin 11 further includes a dispersing mechanism 115. The dispersing mechanism 115 is disposed in a cavity corresponding to the second hopper 112 and / or the third hopper 113, and the dispersing mechanism 115 is used to disperse the raw grain sample entering the fourth hopper 114 from the first hopper 111 or the raw grain sample entering the first hopper 111 from the fourth hopper 114 during the rotation of the mixing bin 11.

[0047] Specifically, when the mixing bin 11 starts to rotate, the raw grain sample 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 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 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 force or impact force when the mixing bin rotates to effectively disperse the samples. By introducing the dispersion mechanism 115, this double-conical unidirectional inward flow mixing device for grain particles can further improve the mixing effect and ensure that the raw grain samples are more evenly and thoroughly mixed in the mixing bin. At the same time, the design also increases the adaptability and flexibility of the equipment, and can handle raw grain samples of different types and characteristics.

[0048] In some embodiments, Figures 1 to 3 As 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 in 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 facing the first hopper 111 and is connected to 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 port 1152 is provided at the other end of the double cone 1151, and a dispersing port cover plate 1153 is provided at the dispersing port 1152. When the second hopper 112 rotates to above the third hopper 113, the dispersing port cover plate 1153 exposes the dispersing port 1152. When the third hopper 113 rotates to above the second hopper 112, the dispersing port cover plate 1153 covers the dispersing port 1152.

[0049] Specifically, when the second hopper 112 rotates to the top of the third hopper 113, the dispersion port cover 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 grid 1154. The ingenious design of the sampling grid 1154 allows the samples to be evenly dispersed during the inflow process. The dispersed samples will experience two main flow paths: a portion of the samples will directly enter the interior of the double cone 1151 through the opening of the sampling grid 1154, and then be exported to the third hopper 113 through the dispersion port 1152. These samples will eventually flow into the fourth hopper 114, completing a circulation cycle.

[0050] The other part of the sample, after being dispersed by the sample dividing grid 1154, will directly fall into the third hopper 113. This part of the sample 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. The cone dispersion method of free fall allows the different particles in the sample to be evenly distributed, achieving the purpose of uniform mixing.

[0051] Next, when the third hopper 113 rotates to the top of the second hopper 112, the dispersion port cover 1153 will adjust its position again to cover the dispersion port 1152. At this time, the raw grain samples in the fourth hopper 114 begin to flow into the third hopper 113. These samples will be dispersed again through the back of the sample grid 1154, and then evenly enter the second hopper 112. Finally, they will flow into the first hopper 111, completing the circulation cycle in another direction.

[0052] During the whole process, the coordination between the dispersion mechanism 115 and the hopper not only ensures the uniform dispersion of the raw grain sample, but also realizes the continuous and efficient flow of the sample. This design greatly improves the efficiency and stability of the raw grain processing system, and provides a reliable guarantee for subsequent processing and testing.

[0053] It should be noted that there are generally multiple sampling grids 1154, and the multiple sampling grids 1154 are sequentially spaced along the circumference of the double cone 1151, and the side walls of adjacent sampling grids 1154 form hollow sampling grids. The design of multiple sampling grids 1154 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.

[0054] In a specific embodiment, the side wall of the double cone 1151 cooperates with the hopper to form a first sample grid and a second sample grid, the first sample grid is provided with an opening toward the first hopper 111, and the second sample grid is a hollow sample grid. Thus, after the material is evenly dispersed by free falling into the double cone 1151, it enters the first sample grid or the second sample grid, and then a part of the sample freely falls into the double cone 1151 through the second sample grid, and the other part of the sample falls into the inside of the double cone 1151 through the first sample grid, and the two parts of the sample are mixed, and the cone dispersion is performed by free falling, and the different particles in the sample are evenly distributed to achieve the purpose of uniform mixing.

[0055] In some embodiments, Figure 1 and Figure 2 As shown, the mixing bin 11 further includes: a first valve 116. The first valve 116 is disposed between the first hopper 111 and the second hopper 112. The first hopper 111 is connected to the second hopper 112 through the first valve 116.

[0056] 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 connected, and to control the flow rate and speed of the raw grain sample from the first hopper 111 into the second hopper 112. By accurately adjusting the opening of the first valve 116, the operator can flexibly control the mixing speed and mixing ratio of the raw grain sample according to actual production needs.

[0057] 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 it is necessary to accurately control the mixing effect or perform special process treatment, the role of the first valve 116 is particularly important.

[0058] In addition, the introduction of the first valve 116 also facilitates the maintenance and cleaning of the mixing bin 11. 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 grain particle double-conical unidirectional inward flow mixing device.

[0059] In another embodiment, if Figure 1 and Figure 2As shown, the mixing bin 11 also includes: a first valve 116 and a second valve 117. The first valve 116 and the second valve 117 can be electromagnetic valves. The first valve 116 is arranged between the first hopper 111 and the second hopper 112. The first hopper 111 is connected to 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 connected to 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 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.

[0060] Specifically, when the second driving mechanism 14 controls the second hopper 112 to rotate to the top 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 loading 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 cover the material port.

[0061] Then, the first valve 116 and the second valve 117 are opened, and the samples in the first hopper 111 begin to flow into the second hopper 112. As the samples continue to enter, they will encounter the sample grid 1154. The ingenious design of the sample grid 1154 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 1151 through the opening of the sample grid 1154, and then be exported to the third hopper 113 through the dispersion port 1152. These samples will eventually flow into the fourth hopper 114, completing a circulation cycle. The other part of the samples, after being dispersed by the sample 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.

[0062] 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 the top of the second hopper 112, the dispersion port cover 1153 will adjust its position again to cover the dispersion port 1152. At this time, open the first valve 116 and the second valve 117, and 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 sample dividing grid 1154, and then evenly enter the second hopper 112. They will flow into the first hopper 111, completing the circulation cycle in the other direction. Finally, after repeating the above operation to the pre-designed mixing number, turn the first hopper 111 downward, open the cover 12, and place the sample in the raw grain sample reduction device to complete the operation.

[0063] Based on the above embodiments, in some embodiments, such as Figure 1 and Figure 2 As 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.

[0064] 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 cover plate 12 is driven to move between the first position and the second position through the telescopic movement of the cylinder 131.

[0065] For example, when the cylinder 131 is in a retracted state, the cover plate 12 is in a closed position, completely covering the material opening of the first hopper 111 , and preventing the raw grain sample from entering the mixing bin from the first hopper 111 .

[0066] 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, allowing the raw grain sample to enter the mixing bin from the first hopper 111 for mixing.

[0067] This design allows the operator to conveniently control the feeding process of the mixing bin by controlling the extension and contraction of the cylinder 131, thereby improving the flexibility and automation of the operation.

[0068] Similarly, based on the above embodiments, in some embodiments, such as Figure 1 and Figure 2As shown, the second driving mechanism 14 includes: a motor 141. The rotating end of the motor 141 is connected to the mixing bin 11, and is used to drive the mixing bin 11 to rotate. The 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 motor 141 can be precisely adjusted by 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 raw grain samples between the hoppers, and improve the uniformity and efficiency of the mixing. The use of the motor 141 ensures the stability and reliability of the rotation process, and provides strong power support for the mixing process.

[0069] In this embodiment, Figure 1 and Figure 2 As 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 motor 141 is connected to the middle of the bracket 142. When the 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.

[0070] Specifically, when it is necessary to add raw grain samples to the mixing bin 11, the cylinder of the first drive mechanism 13 extends, pushing the cover plate 12 away from the material port of the first hopper 111 to expose the material port. When it is necessary to stop adding raw grain samples, the cylinder of the first drive mechanism 13 contracts, pulling the cover plate 12 back to the closed position, preventing the raw grain samples from continuing to enter the mixing bin. Then, the 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 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.
