[0041] The present utility model provides a reduction device for dividing a raw grain sample into four unequal parts, as Figures 1 to 5 shown. The reduction device 3 for dividing a raw grain sample into four unequal parts includes: a material distribution bin 31, a material distribution wheel 32, and a first 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 cavity and a plurality of discharge ports 321 communicating with the cavity. Each discharge port 321 communicates with the feed inlet through the cavity. One of the sub-material cavities communicates with two discharge ports 321, another sub-material cavity communicates with two discharge ports, and yet another sub-material cavity communicates with five discharge ports 321. The first 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 cavity and then enters the cavity. In the case where the first 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.
[0042] 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 ports 321, one sub-cavity is connected to two discharge ports 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 2:2:5.
[0043] 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.
[0044] The utility model provides a reduction device for dividing a raw grain sample into four unequal parts. Through the rotation of the dividing wheel and the cooperation with the side wall of the material cavity, the device can efficiently distribute the raw grain sample into at least three sub-cavities, one of which is connected to two discharge ports, another is connected to two discharge ports, and another 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, and the reduction process can be completed by driving the rotation of the dividing wheel through the first driving mechanism, without complicated operating steps and manual intervention, thereby reducing 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.
[0045] In some embodiments, Figures 1 to 5As shown, the sub-material cavities are the first sub-material cavity, the second sub-material cavity, the third sub-material cavity, and the fourth sub-material cavity respectively. The first sub-material cavity and the second sub-material cavity are communicated with their corresponding two discharge ports 321, and the third sub-material cavity and the fourth sub-material cavity are communicated with their corresponding five discharge ports 321.
[0046] 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 communicated with 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 original grain samples flowing out of the 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.
[0047] The third sub-material cavity and the fourth sub-material cavity are communicated with 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 original grain samples from the corresponding five discharge ports, so 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 original grain samples.
[0048] Through this design of multiple sub-material cavities, the reduction device 3 for unevenly dividing the original grain sample into four parts can simultaneously achieve reductions in multiple 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 communicated with its corresponding discharge port, the reduction process is more accurate and reliable, ensuring the accuracy of experimental and production results.
[0049] In some embodiments, as Figures 1 to 5 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.
[0050] In this embodiment, the first housing 311 and the second housing 312 are docked with each other and closely cooperate to jointly form a closed material chamber. This material chamber is the area for storing and preparing the distribution of raw grain samples. The space between the first housing 311 and the first discharge 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 samples distributed from the material chamber. Immediately afterwards, the space between the first discharge partition and the second discharge 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 samples distributed from the material chamber. The second discharge partition and the third discharge partition form a third sub-material chamber in the material chamber 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 chamber in the material chamber. This sub-material chamber is used to receive and store the fourth part of the raw grain samples distributed from the material chamber.
[0051] For the convenience of exporting the corresponding amount of raw material samples, as Figures 1 to 5 shown, the reduction and division device 3 for unevenly dividing the raw grain samples into four parts 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 chamber. The second discharge pipe 35 is communicated with the second sub-material chamber. The third discharge pipe 36 is communicated with the third sub-material chamber. The fourth discharge pipe 37 is communicated with the fourth sub-material chamber.
[0052] In this embodiment, the first discharge pipe 34 is communicated with the first sub-material chamber for exporting the raw grain samples in the first sub-material chamber. The second discharge pipe 35 is communicated with the second sub-material chamber for exporting the raw grain samples in the second sub-material chamber. The third discharge pipe 36 is communicated with the third sub-material chamber for exporting the raw grain samples in the third sub-material chamber. The fourth discharge pipe 37 is communicated with the fourth sub-material chamber for exporting the raw grain samples in the fourth sub-material chamber. The first sub-material chamber and the second sub-material chamber receive the samples from two discharge ports 321, and the third sub-material chamber and the fourth sub-material chamber receive the samples from five discharge ports 321, so as to achieve the reduction and division with a ratio of 2:2:5:5.
[0053] Optionally, as Figure 1 and Figure 2 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 chamber extend in different directions.
[0054] This design enables each discharge pipe to independently export the raw grain samples in its corresponding sub-material chamber without interfering with or affecting each other. For example, when it is necessary to export the samples in multiple sub-material chambers simultaneously, the staff can easily operate through different discharge pipes without worrying about sample confusion or cross-contamination problems.
[0055] In addition, the discharge 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 discharge pipes can be flexibly placed in appropriate positions to facilitate the operation and observation of the staff.
[0056] In some embodiments, the uneven four-division reduction device 3 for raw grain samples 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.
[0057] 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 simply turning the handle.
[0058] When the first housing 311 and the second housing 312 are locked, their connection will become very stable, which can not only prevent the raw grain samples in the material chamber from leaking, but also ensure a stable operating environment for the dividing 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.
[0059] In addition, as Figure 1 and Figure 2 shown, the uneven four-division reduction device 3 for raw grain samples further includes: a hopper 314 and a feed pipe 315; the hopper 314 is located on one side of the dividing bin 31, and the hopper 314 is communicated with the feed port through the feed pipe 315. The design of the hopper 314 enables the user to conveniently pour the raw grain samples into it, preparing for the subsequent reduction operation. In order to smoothly introduce the raw grain samples in the hopper 314 into the material chamber of the dividing 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 hopper 314, and the other end is connected to the feed port of the dividing bin 31. When the raw grain samples in the hopper 314 accumulate to a certain extent, they will naturally flow into the material chamber of the dividing bin through the feed pipe 315, and then be reduced by the dividing 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 samples, improves work efficiency, but also ensures the continuity and stability of the reduction operation.
[0060] Among them, a valve 316 is provided on the feed pipe 315. The precise control function of the valve 316 enables the user 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 quartering process, but also contributes to improving the accuracy and consistency of the quartering results. By precisely controlling the opening degree of the valve 316, the user 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 quartering process. Secondly, the introduction of the valve 316 also enhances the safety of the quartering device 3 for unevenly dividing the raw grain sample into four parts. During the quartering 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 dividing bin after the equipment stops running, ensuring the smooth progress of the cleaning and maintenance work of the quartering device.
[0061] In some embodiments, such as Figure 3 and Figure 4 shown, a 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. The 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 outflow position and flow rate of the raw grain sample when rotating, thereby realizing the precise quartering of the raw grain sample. At the same time, by adjusting the number, size and distribution position of the discharge ports 321, the quartering effect can be further optimized to meet the requirements of different experiments and productions.
[0062] In this embodiment, as Figure 4 shown, five discharge ports 321 are provided on one end face in the axial direction of the dividing wheel 32, which communicate with the fourth sub-material cavity. Nine discharge ports 321 are provided in the radial direction of the dividing wheel 32, which communicate with the second sub-material cavity, the third sub-material cavity and the fourth sub-material cavity respectively. Among them, the first sub-material cavity and the second sub-material cavity communicate with their corresponding two discharge ports 321, and the third sub-material cavity communicates with its corresponding five discharge ports 321.
[0063] Considering the actual use requirements of the device for dividing the raw grain sample into four unequal parts, 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.
[0064] 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.
[0065] 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.
[0066] This movable cover design not only improves the flexibility and practicality of the device for dividing raw grain samples into four unequal parts, 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.
[0067] In some embodiments, Figure 1 and Figure 2As 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.
