[0002] A grain sampler is a specialized device used to uniformly divide grain samples. It is widely used in grain purchasing, storage, processing, and testing. Its core function is to quickly and accurately separate representative small samples from a large amount of grain, providing a basis for subsequent quality testing (such as the determination of indicators like moisture, impurities, bulk density, and imperfect grains).
[0003] Patent CN220986417U discloses a grain testing and sampling device. The main body of the device includes a working chamber, which is connected to a discharge pipe. The inner wall of the discharge pipe is threaded with a blocking plate. By setting up a hopper, a conveying pipe, a valve, and a working chamber, the user can first put the grain to be tested into the hopper, and then open the valve to put the grain into the working chamber for sampling. However, the above technical solution requires frequent operation by the staff during implementation, relies on manual operation, has low efficiency, and may result in misoperation. Summary of the Invention
[0004] Given that the existing technologies mentioned above require frequent operation by staff, rely on manual operation, have low efficiency, and may result in misoperation.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An intelligent grain sampler includes a dispensing cylinder, a vibrating motor, a feeding port, and a base. The vibrating motor is disposed inside the dispensing cylinder; the feeding port is fixed to the upper end of the dispensing cylinder; the base is welded to the lower end of the dispensing cylinder; and further includes:
[0007] The system includes a control component, a sample dispensing component, and a limiting component; the control component is located on one side of the dispensing cylinder; the sample dispensing component is mounted above the vibrating motor; and the limiting component is mounted on one side of the sample dispensing component.
[0008] As a further embodiment of this utility model: the control component includes: a touch screen and a processor; the touch screen is installed on one side of the dispensing cylinder, near the top; the processor is connected to the electrical output terminal of the touch screen.
[0009] As a further embodiment of this invention, the control component further includes: a first weight sensor and a second weight sensor; the first weight sensor is disposed on one side of the vibration motor; the second weight sensor is disposed at the bottom of the groove of the base.
[0010] As a further embodiment of this utility model: the sample distribution assembly includes: a first connecting rod, a first motor, and a rotating sample distribution disk; the first connecting rod is fixed to the lower end of the first weight sensor; the first motor is keyed to the lower end of the first connecting rod; and the rotating sample distribution disk is installed on the upper end of the first weight sensor.
[0011] As a further embodiment of this utility model: the sample distribution component further includes: a pipe and a storage tank; the pipe is disposed on the outer wall of the distribution cylinder; the storage tank is installed below the end of the pipe.
[0012] As a further embodiment of this utility model: the limiting component includes: a limiting plate and a gear; the limiting plate is slidably connected to the inner wall of the dispensing cylinder; the gear meshes with the inner straight teeth of the limiting plate.
[0013] As a further embodiment of this utility model, the limiting component further includes: a second connecting rod and a second motor; the second connecting rod is keyed to the inside of the gear; the second motor is keyed to the lower end of the second connecting rod.
[0014] As a further embodiment of this utility model, the limiting component further includes: a second sliding plate and a first sliding plate; the second sliding plate is fixed to one side of the limiting plate; the first sliding plate is slidably connected to the inside of the second sliding plate.
[0015] The beneficial effects of this utility model are:
[0016] 1) This utility model controls the start of two sets of second motors to drive the second connecting rod to rotate, which in turn drives the gear to rotate. The inner side of the limiting plate is provided with straight teeth that mesh with the gear, and each limiting plate surface is provided with three sets of discharge ports. Two of these sets overlap with the discharge ports on the surface of the distributing cylinder. When the gear drives the limiting plate to rotate, the discharge ports on the surface of the limiting plate will gradually separate from the overlapping state until they no longer overlap. Therefore, the four sets of discharge ports on the surface of the distributing cylinder cannot discharge material, leaving four sets of discharge ports.
[0017] 2) This utility model controls the rotation of the first motor to drive the rotation of the rotating sample distribution disk, which in turn drives the sample grain to rotate. When the discharge port of the rotating sample distribution disk coincides with the discharge port of the distribution cylinder, the sample grain will enter the remaining four sets of storage boxes through the pipe. The second weight sensor monitors the weight of the sample in the storage box in real time. If the actual weight of the sample is low, the processor will immediately fine-tune the rotation speed of the rotating sample distribution disk to increase the sample distribution amount at the corresponding outlet until the actual weight is consistent with the target weight, ensuring the accuracy of the ratio.
[0018] 3) After the sample is divided, the cleaning process is triggered. The processor will reverse the first motor and start the vibration motor to remove the residual sample and avoid cross-contamination. Attached Figure Description

[0025] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0026] Example 1, please refer to Figures 1-5 This is the first embodiment of the present invention, which provides an intelligent grain sampler, including a dispensing cylinder 1, a vibration motor 2, a feeding port 3, and a base 4. The vibration motor 2 is disposed inside the dispensing cylinder 1; the feeding port 3 is fixed to the upper end of the dispensing cylinder 1; and the base 4 is welded to the lower end of the dispensing cylinder 1. It also includes:
[0027] The control component 5, the sample distribution component 6, and the limiting component 7 are provided. The control component 5 is located on one side of the dispensing cylinder 1. The sample distribution component 6 is installed above the vibrating motor 2. The limiting component 7 is installed on one side of the sample distribution component 6.
[0028] Specifically, the control component 5 includes: a touch screen 501 and a processor 502; the touch screen 501 is installed on one side of the dispensing cylinder 1 near the top; the processor 502 is connected to the electrical output terminal of the touch screen 501.
[0029] The touch screen 501 transmits parameter commands to the processor 502 in real time.
[0030] Specifically, the control component 5 also includes: a first weight sensor 503 and a second weight sensor 504; the first weight sensor 503 is disposed on one side of the vibration motor 2; the second weight sensor 504 is disposed at the bottom of the groove of the base 4.
[0031] The output terminals of the first weight sensor 503 and the second weight sensor 504 are connected to the processor 502.
[0032] Specifically, the sample distribution component 6 includes: a first connecting rod 602, a first motor 601, and a rotating sample distribution disk 603; the first connecting rod 602 is fixed to the lower end of the first weight sensor 503; the first motor 601 is keyed to the lower end of the first connecting rod 602; and the rotating sample distribution disk 603 is installed on the upper end of the first weight sensor 503.
[0033] The electrical output terminal of the processor 502 is connected to the first motor 601.
[0034] In use, the sample grain is fed into the dispensing cylinder 1 through the feeding port 3. The dispensing mode is set via the touch screen 501. If proportional dispensing is selected, assuming a 1:3 dispensing ratio is chosen, this parameter is transmitted to the processor 502 in real time. After receiving the parameter, the processor 502 uses the first weight sensor 503 to collect the total weight of the sample to be dispensed and simultaneously feeds it back to the processor 502. The processor 502 controls the first motor 601 to rotate, driving the rotating dispensing disk 603 to rotate, which in turn drives the sample grain to rotate. When the discharge port of the rotating dispensing disk 603 coincides with the discharge port of the dispensing cylinder 1, the sample grain will enter the remaining four sets of storage boxes 605 through the pipe 604. The second weight sensor 504 monitors the sample weight in the storage box 605 in real time. If the actual sample weight is low, the processor 502 will immediately fine-tune the rotation speed of the rotating dispensing disk 603, increasing the sample dispensing amount at the corresponding outlet until... The actual weight matches the target weight to ensure proportional accuracy. When the second weight sensor 504 detects that the weight of all samples has reached the target value, the processor 502 sends a stop signal, the rotating sample tray 603 stops rotating, and the touch screen 501 displays "Proportional sample distribution complete," prompting the user to remove the samples. If quantitative sample distribution is selected, the rotating sample tray 603 will rotate under the control of the processor 502. When the second weight sensor 504 detects that the weight of the sample grain in the storage box 605 has reached the preset target weight, the processor 502 immediately sends a stop signal. If random sample distribution is selected, the processor 502 has a built-in random algorithm. After the sample distribution program starts, the algorithm will generate dynamic sample distribution points based on preset "random rules," randomly starting and stopping the rotating sample tray 603. Samples are only allowed to enter the storage box 605 through the outlet within the "effective sample distribution area" or "sample distribution time interval" specified by the random algorithm. When the sample distribution is completed, a cleaning program is triggered. The processor 502 will cause the first motor 601 to reverse and start the vibration motor 2 to remove residual samples and avoid cross-contamination.
[0035] In summary, this invention controls the rotation of the first motor 601, which in turn drives the rotating sample dispensing disk 603 to rotate, thereby rotating the sample grains. When the discharge port of the rotating sample dispensing disk 603 coincides with the discharge port of the dispensing cylinder 1, the sample grains will enter the remaining four sets of storage boxes 605 through the pipe 604. The second weight sensor 504 monitors the weight of the sample in the storage box 605 in real time. If the actual weight of the sample is low, the processor 502 will immediately fine-tune the rotation speed of the rotating sample dispensing disk 603, increasing the sample distribution amount at the corresponding outlet until the actual weight matches the target weight, ensuring proportional accuracy. After the sample is dispensed, this invention triggers a cleaning procedure. The processor 502 will reverse the first motor 601 and start the vibration motor 2 to remove residual samples and avoid cross-contamination.
[0036] Example 2, please refer to Figures 1-5 This is the second embodiment of the present utility model.
[0037] Specifically, the sample distribution component 6 also includes: a pipe 604 and a storage tank 605; the pipe 604 is disposed on the outer wall of the distribution cylinder 1; the storage tank 605 is installed below the end of the pipe 604.
[0038] The sample grain enters the storage box 605 through pipe 604.
[0039] Specifically, the limiting component 7 includes: a limiting plate 704 and a gear 703; the limiting plate 704 is slidably connected to the inner wall of the dispensing cylinder 1; the gear 703 meshes with the inner straight teeth of the limiting plate 704.
[0040] The limiting plate 704 has three sets of discharge ports on its surface. The initial positions of the discharge ports at both ends of the limiting plate 704 coincide with the discharge ports of the distributing cylinder 1 and the rotating sample plate 603. When the limiting plate 704 is rotated to the point where it no longer coincides with the discharge ports on the surface of the distributing cylinder 1, the sample will not be able to enter the storage box 605 through the pipe 604. However, if the limiting plate 704 is rotated further, the discharge port at its middle position will coincide with one of the discharge ports of the distributing cylinder 1. At this time, the number of discharge ports opened by the distributing cylinder 1 can be arbitrarily controlled.
[0041] Specifically, the limiting component 7 also includes: a second connecting rod 702 and a second motor 701; the second connecting rod 702 is keyed to the inside of the gear 703; the second motor 701 is keyed to the lower end of the second connecting rod 702.
[0042] The electrical output terminal of the processor 502 is connected to the second motor 701.
[0043] Specifically, the limiting component 7 also includes: a second sliding plate 706 and a first sliding plate 705; the second sliding plate 706 is fixed to one side of the limiting plate 704; the first sliding plate 705 is slidably connected to the inside of the second sliding plate 706.
[0044] The second sliding plate 706 and the first sliding plate 705 prevent the sample from falling to the bottom of the dispensing cylinder 1 when the rotating sample dispensing disk 603 rotates.
[0045] In use, the processor 502 calculates the weight of a single sample according to the selected ratio and controls the two sets of second motors 701 to start, driving the second connecting rod 702 to rotate, which in turn drives the gear 703 to rotate. The inner side of the limiting plate 704 is provided with straight teeth that mesh with the gear 703, and each limiting plate 704 surface is provided with three sets of discharge ports, two of which overlap with the discharge ports on the surface of the distributing cylinder 1. When the gear 703 drives the limiting plate 704 to rotate, the discharge ports on the surface of the limiting plate 704 will gradually separate from the overlapping state until they no longer overlap. Therefore, the four sets of discharge ports on the surface of the distributing cylinder 1 cannot discharge material, leaving four sets of discharge ports.
[0046] In summary, this utility model controls the start of two sets of second motors 701, which drive the second connecting rod 702 to rotate, thereby driving the gear 703 to rotate. The inner side of the limiting plate 704 is provided with straight teeth that mesh with the gear 703, and each limiting plate 704 has three sets of discharge ports on its surface. Two of these sets overlap with the discharge ports on the surface of the distributing cylinder 1. When the gear 703 drives the limiting plate 704 to rotate, the discharge ports on the surface of the limiting plate 704 will gradually separate from the overlapping state until they no longer overlap. Therefore, the four sets of discharge ports on the surface of the distributing cylinder 1 cannot discharge material, leaving four sets of discharge ports.

Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
