[0038] The utility model provides a device for dividing grain samples into unequal parts, such as Figures 1 to 5As shown, the unequally divided grain sample reduction device 3 comprises: a material dividing bin 31, a material dividing wheel 32 and a first driving mechanism 33. The material dividing bin 31 is formed with a material cavity and a feed port. The material dividing wheel 32 is rotatably arranged in the material cavity, and the material cavity is divided into at least three sub-cavities by the side wall of the material cavity. The material dividing wheel 32 is formed with a cavity and a plurality of discharge ports 321 connected to the cavity, and each discharge port 321 is connected to the feed port through the cavity, wherein one sub-cavity is connected to one discharge port 321, another sub-cavity is connected to two discharge ports, and another sub-cavity is connected to five discharge ports 321. The first driving mechanism 33 is transmission-connected with the dividing wheel 32, and is used for driving the dividing wheel 32 to rotate in the material cavity, so that the raw grain sample introduced from the feed port enters the cavity and then enters the cavity. When the first driving mechanism 33 drives the dividing wheel 32 to rotate, the raw grain sample can enter different sub-cavities through the discharge port 321. By setting different numbers of discharge ports 321, a 1:2:5 reduction can be achieved.
[0039] In this embodiment, the dividing bin 31 serves as the main structure of the entire device, and a material cavity for reducing the raw grain sample is formed inside it. A feed port is provided on one side of the material cavity, which is used to introduce the raw grain sample to be reduced into the device. The dividing wheel 32 can not only rotate freely, but also its design is cleverly matched with the side wall of the material cavity, dividing the material cavity into at least three sub-cavities. A cavity is formed inside the dividing wheel 32, and this cavity is connected to the feed port of the material cavity. More importantly, a plurality of discharge ports 321 are also provided on the dividing wheel 32, and these discharge ports 321 are all connected to the cavity. When the dividing wheel 32 rotates, the raw grain sample introduced from the feed port will first enter the cavity, and then enter different sub-cavities through specific discharge ports 321. This design enables the raw grain sample to be effectively distributed to different sub-cavities during the rotation of the dividing wheel 32. Specifically, in the design of the discharge port 321, one sub-cavity is connected to only one discharge port 321, another sub-cavity is connected to two discharge ports 321, and another sub-cavity is connected to five discharge ports 321. This design ingeniously realizes the reduction of the raw grain sample, so that the ratio of the sample amount in one sub-cavity to the sample amount in other sub-cavities reaches a ratio of 1:2:5.
[0040] In order to drive the rotation of the material distribution wheel 32, the device is also equipped with a first driving mechanism 33. The first driving mechanism 33 is connected to the material distribution wheel 32 in a transmission manner, and ensures that the material distribution wheel 32 rotates in the material cavity at a predetermined speed and direction by providing stable power. In this way, the raw grain sample can be accurately distributed to different sub-cavities through the discharge port 321, achieving efficient and accurate reduction.
[0041] The utility model provides a device for reducing grain samples in unequal portions. Through the rotation of the dividing wheel and the cooperation with the side wall of the material chamber, the device can efficiently distribute the raw grain sample into at least three sub-cavities, one of which is connected to one discharge port, another is connected to two discharge ports, and another is connected to five discharge ports, thereby achieving an accurate reduction ratio of 1:2:5. This reduction method is faster and more accurate than the traditional manual reduction method. The structure of the device is simple and clear. The reduction process can be completed by driving the rotation of the dividing wheel through the first driving mechanism. No complicated operating steps and manual intervention are required, which reduces the difficulty of operation and labor costs. Since the dividing wheel is provided with a plurality of discharge ports connected to the cavity, and each discharge port accurately corresponds to a sub-cavity, it can ensure that the sample quantity ratio in each sub-cavity after reduction is accurate and correct, meeting the needs of scientific experiments and production.
[0042] In some embodiments, Figures 1 to 5 As shown, the sub-material chambers are respectively the first sub-material chamber, the second sub-material chamber, the third sub-material chamber, the fourth sub-material chamber and the fifth sub-material chamber. The first sub-material chamber, the second sub-material chamber and the third sub-material chamber are connected to a corresponding discharge port 321, the fourth sub-material chamber is connected to two corresponding discharge ports 321, and the fifth sub-material chamber is connected to five corresponding discharge ports 321.
[0043] Specifically, among the five sub-cavities, the design principles of the first sub-cavity, the second sub-cavity, and the third sub-cavity are similar, and they are all directly connected to a corresponding specific discharge port 321. When the dividing wheel 32 rotates in the cavity, these sub-cavities will receive the raw grain samples flowing out of the cavity through their respective discharge ports. Since each sub-cavity is only connected to one discharge port, the amount of samples they receive is relatively small, but it is sufficient to meet specific experimental or production needs.
[0044] The fourth sub-material chamber is connected to the two discharge ports 321. When the dividing wheel 32 rotates, the fourth sub-material chamber will receive raw grain samples from the two discharge ports at the same time, so the amount of samples it receives will be more than the other sub-material chambers. This design enables the fourth sub-material chamber to store more reduced raw grain samples. The fifth sub-material chamber is connected to the five discharge ports 321. This means that when the dividing wheel 32 rotates, the fifth sub-material chamber will receive raw grain samples from the five discharge ports at the same time, so the amount of samples it receives will be much more than the other sub-material chambers. This design enables the fifth sub-material chamber to store a large number of reduced raw grain samples to meet the needs of large-scale experiments or production.
[0045] Through the design of multiple sub-cavities, the unequally divided grain sample reduction device 3 can simultaneously achieve multiple reductions in different proportions (achieving reductions in proportions of 1:1:1:2:5), thereby improving the flexibility and practicality of the device. At the same time, since each sub-cavity is directly connected to its corresponding discharge port, the reduction process is more precise and reliable, thereby ensuring the accuracy of the experimental and production results.
[0046] In some embodiments, Figures 1 to 5 As shown, the material distribution bin 31 includes: a first shell 311, a second shell 312, and a first discharge baffle, a second discharge baffle, a third discharge baffle and a fourth discharge baffle which are arranged in sequence along the circumference of the material distribution wheel 32; the first shell 311 and the second shell 312 are connected to each other to form a material cavity, the first shell 311 and the first discharge baffle form a first sub-material cavity, the first discharge baffle and the second discharge baffle form a second sub-material cavity in the material cavity, the second discharge baffle and the third discharge baffle form a third sub-material cavity in the material cavity, the third discharge baffle and the fourth discharge baffle form a fourth sub-material cavity in the material cavity, and the fourth discharge baffle and the second shell 312 form a fifth sub-material cavity in the material cavity.
[0047] In this embodiment, the first shell 311 and the second shell 312 are docked with each other, and the two are closely matched to form a closed material chamber. This material chamber is an area for storing and preparing to distribute raw grain samples. The space between the first shell 311 and the first discharging partition is defined as the first sub-material chamber. This sub-material chamber is used to receive and store the first part of the raw grain sample distributed from the material chamber. Next, the space between the first discharging partition and the second discharging partition forms an independent area in the material chamber, which is the second sub-material chamber. It is also used to receive and store the second part of the raw grain sample distributed from the material chamber. The second discharging partition and the third discharging partition form a third sub-material chamber in the material chamber for storing the third part of the raw grain sample. Similarly, the space between the third discharging partition and the fourth discharging partition constitutes a fourth sub-material chamber for storing the fourth part of the raw grain sample. Finally, the space between the fourth discharging partition and the second shell 312 forms a fifth sub-material chamber in the material chamber. This sub-material chamber is used to receive and store the fifth part of the raw grain sample distributed from the material chamber.
[0048] In order to facilitate the export of the corresponding amount of raw material samples, Figures 1 to 5 As shown, the unequally divided food sample reduction device 3 also includes: a first discharge pipe 34, a second discharge pipe 35, a third discharge pipe 36, a fourth discharge pipe 37 and a fifth discharge pipe 38. The first discharge pipe 34 is connected to the first sub-material cavity. The second discharge pipe 35 is connected to the second sub-material cavity. The third discharge pipe 36 is connected to the third sub-material cavity. The fourth discharge pipe 37 is connected to the fourth sub-material cavity. The fifth discharge pipe 38 is connected to the fifth sub-material cavity.
[0049] In this embodiment, the first discharge pipe 34 is connected to the first sub-material chamber, and is used to export the raw grain sample in the first sub-material chamber. The second discharge pipe 35 is connected to the second sub-material chamber, and is used to export the raw grain sample in the second sub-material chamber. The third discharge pipe 36 is connected to the third sub-material chamber, and is used to export the raw grain sample in the third sub-material chamber. The fourth discharge pipe 37 is connected to the fourth sub-material chamber, and is used to export the raw grain sample in the fourth sub-material chamber. The fourth sub-material chamber receives samples from two discharge ports 321. The fifth discharge pipe 38 is connected to the fifth sub-material chamber. Since the fifth sub-material chamber receives samples from five discharge ports 321, the fifth discharge pipe 38 will be responsible for exporting a relatively large amount of raw grain samples in this sub-material chamber, thereby achieving a reduction ratio of 1:1:1:2:5.
[0050] Alternatively, if Figure 1 and Figure 2 As shown, the first discharge pipe 34, the second discharge pipe 35, the third discharge pipe 36, the fourth discharge pipe 37 and the fifth discharge pipe 38 extend in different directions away from one end of the material cavity.
[0051] This design allows each discharge pipe to independently export the raw grain sample in its corresponding sub-cavity without interfering or affecting each other. For example, when it is necessary to export samples from multiple sub-cavities at the same time, the staff can easily operate through different discharge pipes without worrying about sample confusion or cross contamination.
[0052] In addition, the discharge pipe extends in different directions, which also facilitates the layout and installation of the equipment. In practical applications, the discharge pipe can be flexibly placed in a suitable position according to specific site conditions and operation requirements to facilitate operation and observation by staff.
[0053] In some embodiments, the food sample unequally divided reduction device 3 further includes: a locking shaft 39. A connecting seat 313 is provided on the first shell 311 and the second shell 312, and the locking shaft 39 is rotatably passed through the connecting seat 313 and the external structure.
[0054] Specifically, the locking shaft 39 is rotatably provided on the connecting seat 313 and the external structure, and such a design allows the user to lock or loosen the first shell 311 and the second shell 312 by operating the locking shaft 39. A handle is provided at one end of the locking shaft 39 for easy gripping, and the user only needs to gently turn the handle to easily lock or loosen the shell.
[0055] When the first shell 311 and the second shell 312 are locked, the connection between them becomes very stable, which can not only prevent the raw grain sample in the material chamber from leaking, but also ensure that the material distribution wheel 32 maintains a stable operating environment during the rotation process. When cleaning, maintenance or replacement of parts is required, the user only needs to reversely rotate the handle of the locking shaft 39 to easily separate the two shells, which provides convenience for maintenance work.
[0056] In addition, if Figure 1 and Figure 2 As shown, the unequally divided grain sample reduction device 3 also includes: a hopper 314 and a feed pipe 315; the hopper 314 is located on one side of the sub-bin 31, and the hopper 314 is connected to the feed port through the feed pipe 315. The design of the hopper 314 allows the user to easily pour the raw grain sample into it, so as to prepare for the subsequent reduction operation. In order to smoothly introduce the raw grain sample in the hopper 314 into the material cavity of the sub-bin, the device is also equipped with a feed pipe 315. One end of the feed pipe 315 is connected to the bottom of the hopper 314, and the other end is connected to the feed port of the sub-bin 31. When the raw grain samples in the hopper 314 accumulate to a certain extent, they will naturally flow into the material cavity of the sub-bin through the feed pipe 315, and then be reduced by the sub-bin wheel 32 according to a predetermined ratio. The design of the hopper 314 and the feed pipe 315 not only simplifies the introduction process of the raw grain sample and improves the work efficiency, but also ensures the continuity and stability of the reduction operation.
[0057] Among them, a valve 316 is provided on the feed pipe 315. The precise control function of the valve 316 allows the user to adjust the flow rate and entry speed of the sample at any time as needed. This adjustment is not only conducive to ensuring the stability and continuity of the reduction process, but also helps to improve the accuracy and consistency of the reduction results. By accurately controlling the opening degree of the valve 316, the user can ensure that the raw grain sample flows into the sub-bin at an appropriate speed, thereby avoiding the accumulation or overflow of the sample in the material chamber, and ensuring the smooth progress of the reduction process. Secondly, the introduction of the valve 316 also enhances the safety of the reduction device 3 with unequal grain samples. During the reduction process, if an abnormal situation occurs or an emergency stop operation is required, the user can quickly close the valve 316 to cut off the inflow of the sample, thereby avoiding possible dangers or losses. In addition, the valve 316 can also prevent the raw grain sample in the hopper 314 from continuing to flow into the sub-bin after the equipment stops running, ensuring the smooth cleaning and maintenance of the reduction device.
[0058] In some embodiments, Figure 3 and Figure 4As shown, a cavity is formed in the dividing wheel 32, and a plurality of discharge ports 321 are formed on the axial and / or radial side walls of the dividing wheel 32. The axial discharge ports refer to the discharge ports distributed along the axial direction of the dividing wheel 32, which are usually located on both sides of the dividing wheel to ensure that the raw grain sample can flow out in the axial direction when the dividing wheel rotates. The radial discharge ports refer to the discharge ports distributed along the radial direction of the dividing wheel, which are usually evenly distributed on the side walls of the dividing wheel, so that the raw grain sample can flow out in the radial direction when the dividing wheel rotates. This design enables the dividing wheel 32 to accurately control the outflow position and flow rate of the raw grain sample when it rotates, thereby realizing accurate reduction of the raw grain sample. At the same time, by adjusting the number, size and distribution position of the discharge ports 321, the reduction effect can be further optimized to meet the needs of different experiments and production.
[0059] In this embodiment, Figure 4 As shown, one axial end face of the material dividing wheel 32 is provided with a discharge port 321, which is connected to the first sub-material cavity. The other end face is provided with five discharge ports 321, which are connected to the fifth sub-material cavity. Four discharge ports 321 are provided in the radial direction of the material dividing wheel 32, which are respectively connected to the second sub-material cavity, the third sub-material cavity, and the fourth sub-material cavity, wherein the second sub-material cavity and the third sub-material cavity are connected to one discharge port 321 corresponding to them, and the fourth sub-material cavity is connected to two discharge ports 321 corresponding to it.
[0060] Considering the actual use requirements of the unequally divided food sample reduction device, the design of the 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 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 hopper 314 and a second position that exposes the entrance of the hopper 314 through the drive of the second driving mechanism.
[0061] When the cover is in the first position, it completely blocks the entrance of the hopper 314 to prevent the raw grain sample from overflowing from the hopper or being contaminated by the outside world. This design is particularly useful when there is no need to add samples to the hopper, as it ensures that the inside of the hopper is clean and dry to prevent the sample from getting wet or deteriorating.
[0062] When it is necessary to add a raw grain sample to the hopper, the second drive mechanism drives the cover plate to move from the first position to the second position, exposing the entrance of the hopper 314. At this time, the user can conveniently pour the sample into the 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 hopper again.
[0063] This movable cover design not only improves the flexibility and practicality of the unequally divided 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.
[0064] In some embodiments, Figure 1 and Figure 2 As shown, the first driving mechanism 33 includes: a motor 331 and a reducer 332. The rotating shaft of the motor 331 is connected to the material distribution wheel 32 through the reducer 332. As the core component of the entire drive system, the 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 material distribution wheel 32. The selection of the 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 motor 331 and the material distribution wheel 32, which plays a role in reducing the speed and increasing the torque. Since the speed generated by the motor 331 is usually high, and the speed required by the material distribution 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 material distribution wheel 32. The rotating shaft of the motor 331 is connected to the material distribution wheel 32 through the reducer 332, forming a complete power transmission path. When the motor 331 is started, the rotation torque generated by it is converted by the reducer 332 and then transmitted to the material distribution wheel 32, driving it to rotate. During the rotation process, the position of the discharge port 321 on the material distribution wheel 32 changes, thereby realizing the distribution of the raw grain sample.
