Description

Technical Field

[0001] The utility model relates to the field of grain and oil inspection, in particular to a device for dividing a raw grain sample into one and five unequal parts. Background Art

[0002] In the field of grain and oil inspection, sample reduction is an important step to ensure the accuracy of grain and oil quality monitoring. In the traditional grain and oil inspection process, representative samples drawn from large granaries usually need to go through a series of complex processing steps to meet the sample volume requirements of different inspection items.

[0003] However, existing sample reducers have significant limitations and shortcomings during operation. Most of the sample reducers on the market currently rely on manual operation or simple mechanical devices, and usually require multiple mixing and reduction processes to reduce the original sample to the required amount. This method is not only complicated to operate, but also inefficient and often accompanied by high labor intensity. In addition, multiple operations may cause uneven sample mixing, which in turn affects the representativeness of the sample after reduction and reduces the accuracy of the test results. With the development of modern science and technology, the requirements for the intelligence and automation level of equipment in the field of grain and oil inspection are increasing. However, the existing sample reducers are generally low in intelligence and cannot meet the requirements of modern grain and oil inspection processes for efficiency, accuracy and convenience.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] The utility model provides a device for dividing a raw grain sample into one and five unequal parts, such as Figures 1 to 5 As shown, the device 3 for dividing the raw grain sample into five unequal parts comprises: a dividing bin 31, a dividing wheel 32 and a first driving mechanism 33. The dividing bin 31 is formed with a material cavity and a feed port. The dividing wheel 32 is rotatably arranged in the material cavity, and the material cavity is divided into at least two sub-cavities by the side wall of the cavity. The 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, and another sub-cavity is connected to six 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-material cavities through the discharge port 321. By setting different numbers of discharge ports 321, a 1:6 reduction can be achieved.

[0043] 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 two 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 of the sub-cavities is connected to only one discharge port 321, while the other sub-cavity is connected to six discharge ports 321. This design cleverly achieves the reduction of the raw grain sample, so that the ratio of the sample amount in one sub-cavity to the sample amount in another sub-cavity reaches 1:6.

[0044] 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.

[0045] The utility model provides a device for reducing a raw grain sample into five unequal parts. 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 two sub-cavities, one of which is connected to six discharge ports, thereby achieving an accurate reduction ratio of 1:6. 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.

[0046] 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, the third sub-material chamber and the fourth sub-material chamber are all connected to a corresponding discharge port 321, and the fifth sub-material chamber is connected to six corresponding discharge ports 321.

[0047] Specifically, among the five sub-cavities, the design principles of the first sub-cavity, the second sub-cavity, the third sub-cavity and the fourth 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 enough to meet specific experimental or production needs.

[0048] The design of the fifth sub-material chamber is different. It is connected to the six discharge ports 321. This means that when the dividing wheel 32 rotates, the fifth sub-material chamber will receive raw grain samples from the six discharge ports at the same time, so the amount of samples it receives will be much larger than that of 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.

[0049] Through the design of multiple sub-cavities, the device 3 for dividing the raw grain sample into one and five unequal parts can simultaneously realize multiple reductions in different proportions (realizing a reduction ratio of 1:1:1:1:6), 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.

[0050] 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.

[0051] 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.

[0052] In order to facilitate the export of the corresponding amount of raw material samples, Figures 1 to 5 As shown, the device 3 for dividing the raw grain sample into five unequal parts 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.

[0053] 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 fifth discharge pipe 38 is connected to the fifth sub-material chamber. Since the fifth sub-material chamber receives samples from six discharge ports, 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 1:1:1:1:6.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] In some embodiments, the device 3 for dividing the raw grain sample into one and five unequal parts 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.

[0058] 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.

[0059] 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.

[0060] In addition, if Figure 1 and Figure 2 As shown, the device 3 for dividing the raw grain sample into five unequal parts 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 dividing wheel 32 according to a predetermined ratio. The design of the hopper 314 and the feed pipe 315 not only simplifies the process of introducing raw grain samples and improves work efficiency, but also ensures the continuity and stability of the reduction operation.

[0061] 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 in which the raw grain sample is divided into five unequal parts. 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.

[0062] In some embodiments, Figure 3 and Figure 4 As 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.

[0063] In this embodiment, Figure 4 As shown, one axial end face of the 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 six discharge ports 321, which are connected to the fifth sub-material cavity. The radial direction of the dividing wheel 32 is provided with three discharge ports, which are respectively connected to the second sub-material cavity, the third sub-material cavity, and the fourth sub-material cavity.

[0064] 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.
