Description

Technical Field

[0001] The present invention relates to the technical field of sampling, and in particular to a multi-rod intelligent sampling machine and a sampling system thereof. Background Art

[0002] A grain sampling machine is a commonly used sampling device for checking grain quality in grain piles. Its key technology lies in the transmission mechanism that enables the sampling tube to be moved to different positions above the grain pile, as well as the up-and-down movement of the sampling tube to complete sampling of grain from each layer of the pile. The sampling and testing performed by the grain sampling machine ensures that grain storage companies can provide a variety of technical data on grain before and during storage, providing a scientific basis for safe and sound grain storage.

[0003] The multi-rod intelligent sampling machine with the publication number CN117491057A is engaged with the inner rack seat through the limit gear, so that the outer movable frame can slide horizontally along the outer wall of the limit seat, ensuring that the sampling rod can face the upper end of the continuous singing feeding port, thereby facilitating the subsequent layered sampling. After reaching the sampling position, the electric telescopic rod at the bottom can be started, and its output end pushes the material receiving frame to extend along the bottom of the layered material receiving rod. At this time, the feeding port is exposed around the grain. Under the action of gravity, the grain at this depth enters along the material receiving frame. The interior of the socketed frame can be used to complete the layered sampling effect, which can achieve integrated layered sampling and storage, greatly improving the sampling efficiency and the efficiency of winding roller disassembly and processing, and the separated winding roller can be supported by the bottom support ring. However, for larger grain transport vehicles such as vehicle-mounted packaged grain and uncovered bulk grain transport vehicles, it is difficult to move the sampling rod deep into the grain transport vehicle to be sampled through the rotating arm and hydraulic cylinder on the vehicle-mounted sampling machine. For this reason, we propose a multi-rod intelligent sampling machine and its sampling system to solve the above technical problems. Summary of the Invention

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0031] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0032] See also Figure 1-11The present invention provides a technical solution: a multi-rod intelligent sampling machine of the present invention includes: a base plate 1, a mounting frame 2 is connected to the base plate 1; a canopy 3, the canopy 3 is connected to the mounting frame 2, and a workbench 4 is connected under the canopy 3; a sampling mechanism 5, the sampling mechanism 5 is arranged inside the canopy 3, and the sampling mechanism 5 is used to take out grain; a moving mechanism 6, the moving mechanism 6 is connected to the workbench 4, and the moving mechanism 6 is used to drive the sampling mechanism 5 to move horizontally; an adjusting mechanism 7, one side of the adjusting mechanism 7 is connected to the moving mechanism 6, and the other side of the adjusting mechanism 7 is connected to the sampling mechanism 5, and the adjusting mechanism 7 is used to drive the sampling mechanism 5 to move horizontally and longitudinally; a barrier rod 8, the barrier rod 8 is arranged on the base plate 1, three moving mechanisms 6 are provided, and each moving mechanism 6 is connected to two adjusting mechanisms 7.

[0033] In this embodiment, by driving the onboard packaged grain and the uncovered bulk grain truck into the canopy 3, sampling and testing can be carried out through the sampling mechanism 5, and grain sampling can be carried out simultaneously by multiple sampling mechanisms 5, thereby significantly improving the sampling efficiency and accuracy. In a large-volume transport vehicle, multiple sampling mechanisms 5 can more comprehensively cover the entire grain storage area to ensure that each area can be effectively sampled. Through the combination of the moving mechanism 6 and the adjusting mechanism 7, the sampling mechanism 5 can not only move laterally but also be adjusted longitudinally, which enables the equipment to adapt to grain trucks of different types and sizes. Regardless of the distribution height of the grain in the vehicle or the different sizes of the carriages, the sampling position can be flexibly adjusted to achieve automated adjustment and operation, which not only reduces the burden of manual operation but also improves the safety and accuracy of the operation. Operators can conveniently operate multiple mechanisms through a simple control panel or remote control device. The combination of multiple adjustment mechanisms 7 and moving mechanisms 6 enables the system to quickly and flexibly complete sampling tasks in different areas, reducing the necessity of manual intervention, thereby improving the overall efficiency of the operation, solving the limitations of traditional equipment on large-volume grain transport vehicles, and performing outstandingly in improving operational efficiency, accuracy, safety and ease of operation. Through intelligent and automated technologies, the sampling process is optimized, and it has broad application prospects.

[0034] Specifically, the intelligent grain sampling machine has undergone numerous refinements across its various systems, significantly reducing product failure and program error rates. Several protection devices have been added to prevent improper operation of the system and vehicle, as well as speed regulation for various movements. The speed of the vehicle, probe, and other components can be adjusted to meet specific requirements. Improved detection of probe bottoming has been implemented to prevent damage to the vehicle floor or probe. Effective improvements have been made to address issues such as grain sample breakage and excessive impurities during sampling. Most devices are constructed of cold-resistant materials and feature frost-resistant structures, ensuring normal operation even in the harshest winter weather.

[0035] Among them, it has a voice reminder design, and multiple voice prompts are designed using voice software. There are corresponding voice prompts for each step from before the vehicle enters the equipment to the completion of sampling. The rise and fall of the barrier pole 8 ensures the safety of vehicle passage and makes the equipment run reliably and safely.

[0036] Specific sampling process:

[0037] In the initial state of the equipment, the red light at the entrance is on, the green light at the exit is on, the barrier pole is raised, the fan is stopped, all solenoid valves are closed, and the trolley, carriage, and rod are all at the origin.

[0038] The operator clicks the "Vehicle Entry" voice prompt, and a voice prompt appears: "Driver, please confirm the vehicle's height and width. Enter the sampling area slowly and centered along the ground markings. Stop after confirming that the front guardrail of the vehicle has passed the side markings." After the voice prompt ends, the two-way wait at the entrance is activated, and the red light at the exit illuminates, and the barrier gate drops.

[0039] When the vehicle enters the sampling area, if the position is not suitable, the operator clicks the voice bar "a little forward" and "a little back" to instruct the driver to adjust the position. After confirming that the position is correct, click the voice bar "Driver, please stop the vehicle, turn off the engine, apply the brake, get off the vehicle, and take samples in the waiting area."

[0040] After confirming that the driver has arrived at the waiting area, click the Start Sampling button to begin automatic sampling. Once sampling is complete, the device will automatically return to its initial state and announce, "Sampling completed. Please drive slowly out of the sampling area."

[0041] When the sampling machine is working, the grain samples taken are directly transported to the storage container in the laboratory through the pipeline (polyurethane steel wire flexible pipeline).

[0042] The laboratory technician confirms the quantity of grain samples and notifies the operator through voice hardware (a two-way fixed voice device, the voice bar can be edited as needed, and the voice is played by clicking the corresponding text bar, without generating additional information communication). The operator determines whether to take samples again based on the laboratory technician's feedback, or to let the vehicle leave after sampling is completed.

[0043] After sampling is complete, the grain truck exits the canopy and awaits the sample test results in a waiting area. Vehicles whose grain sample test results meet the grain receiving standards register at the gate, enter the warehouse, and proceed directly to the weighbridge for gross weight. Unloading and other processing steps then proceed. Vehicles with unqualified test results exit the waiting area and exit the road. Vehicles requiring resampling must queue up again and continue the sampling process.

[0044] The fan, dust removal tank, fine filter and other equipment of the vacuum sampling system in the sampler are installed in the mobile cabin, and the electrical cabinet and operating table are placed in the operating room.

[0045] The laboratory is set up at a location close to the sampling shed and separated from the operation room. Storage hopper sample rack and other necessary equipment are installed next to the laboratory table.

[0046] The total power cable of the sampling machine goes directly into the control room. The multi-rod intelligent sampling machine has a high degree of automation and simple operation, and the operator only needs simple training to use it; the video surveillance equipment is combined with the equipment control to realize remote operation and control of the equipment; the sampling process is orderly and can work around the clock without being affected by the weather environment; the labor intensity and work danger of the staff in the sampling process are avoided; the fully automatic sampling and transportation links avoid the influence of human factors and improve work efficiency; it has a wide range of applications and strong practicality, and is suitable for warehousing, grain deep processing and other enterprises.

[0047] like Figure 6 and Figure 9 As shown, the sampling mechanism 5 includes a sampling body 51, which is connected to the adjustment mechanism 7. A sampling rod 52 is provided on the sampling body 51, and a driving member 53 for driving the sampling rod 52 to move up and down is provided on one side of the sampling body 51; the driving member 53 on the sampling body 51 drives the sampling rod 52 to move up and down according to instructions. The lifting process can adjust different depths and positions according to sampling requirements to obtain representative samples. After the sampling rod 52 reaches the target position, it will be inserted into the material for sampling. According to the sampling requirements, the sampling rod may continue to penetrate deeper into the material, or stop after a certain depth and recover the sample. During the entire sampling process, the system can monitor the position, depth and other information of the sampling rod in real time, and record the sampling data for subsequent analysis and verification.

[0048] Specifically, the driving motor of the sampling rod 52 probe driver adopts an automatic bottoming detection system, which can reduce the impact and reduce the pressure after the probe touches the bottom, without causing hardware damage or piercing the car. After the probe touches the bottom, the command is transmitted to the PLC to stop the motor, which is flexible and reliable.

[0049] like Figure 6 and Figure 7As shown, specifically, the moving mechanism 6 includes a moving frame 61 and a slide rail 62. A slide frame 63 adapted to the slide rail 62 is provided below the moving frame 61, and a driving wheel 64 and a positioning wheel 65 are provided inside the slide frame 63. A driving motor is provided on one side of the driving wheel 64, and the slide rail 62 is connected to the workbench 4; when it is necessary to move the sampling system to a different position, the driving motor is started, and the slide frame 63 is driven to move along the slide rail 62 through the driving wheel 64. During the movement of the slide frame 63, the positioning wheel 65 ensures the stability of the slide frame to avoid slide rail deviation or unnecessary shaking. After the slide frame and the moving frame move to the specified position, they are precisely positioned by the motor and control system to ensure that the sampling mechanism can perform the sampling operation in the correct area. Once the system reaches the target position, the driving motor will stop, and the moving frame and the slide frame will be fixed in a specific position for subsequent sampling or other operations. The moving mechanism 6 can accurately control the position of the sampling equipment to ensure error-free positioning during the sampling process, making the entire sampling process efficient and stable.

[0050] like Figure 6 and Figure 8 As shown, specifically, the adjustment mechanism 7 includes an adjustment frame 71 and a tooth plate 72. One side of the adjustment frame 71 is connected to the sampling mechanism 5, and the other side of the adjustment frame 71 is connected to a forward and reverse motor 73. The forward and reverse motor 73 is provided with a gear 74 that meshes with the tooth plate 72. When the position of the sampling mechanism 5 needs to be adjusted, the forward and reverse motor 73 begins to operate. According to the adjustment requirements, the motor 73 begins to rotate, driving the gear 74 to rotate. The rotation of the gear 74 drives the tooth plate 72 along a predetermined track. Due to the meshing structure of the tooth plate 72 and the gear 74, the linear movement of the tooth plate is very precise, and small adjustments can be made. As the tooth plate 72 moves back and forth, the position of the adjustment frame 71 and the connected sampling mechanism 5 is precisely adjusted. This process can be a dynamic adjustment based on the needs of the system. After the adjustment is completed, the motor stops, and the adjustment frame 71 and the tooth plate 72 are fixed in the target position, ensuring that the sampling mechanism 5 operates stably in the new position.

[0051] like Figure 6 and Figure 7As shown, the moving frame 61 is provided with a first limiting slide bar 66, a second limiting slide bar 67 and a third limiting slide bar 68 in sequence from top to bottom, the sampling body 51 is connected to the first limiting slide bar 54 and the second limiting slide bar 55, the first limiting slide bar 54 is adapted to the first limiting slide bar 66, the second limiting slide bar 55 is adapted to the third limiting slide bar 68, and limiting wheels 56 are provided inside the first limiting slide bar 54 and the second limiting slide bar 55, and a limiting baffle 75 adapted to the second limiting slide bar 67 is provided on the adjustment frame 71; the first limiting slide bar 66 and the third limiting slide bar 68 limit the first limiting slide bar 54 and the second limiting slide bar 55, thereby enhancing the stability of the sampling body 51 when moving, and the limiting baffle 75 is limited by the second limiting slide bar 67, thereby enhancing the stability of the adjustment mechanism 7 when moving.

[0052] like Figure 1 and Figure 2 As shown, specifically, a walking ladder 9 is provided on the canopy 3, and a working frame 10 is provided on the moving mechanism 6; the columns of the canopy 3 are made of 396×198mm square H-steel; the longitudinal rails are made of 125×250mm rectangular H-steel, which has the characteristics of beautiful appearance, good strength and stability.

[0053] The sampling machine and canopy are installed outside the grain depot yard or at the entrance, measuring 6.25 meters wide, 18.5 meters long, and 10 meters high. Trusses connect the sampling machine canopy, control room, and laboratory to cables, grain pipes, and other equipment. The main power supply is connected to the main control cabinet as close as possible. Support columns are installed on the side of the truss closest to the wall, with a minimum height of 5 meters.

[0054] Specifically, a camera, a lighting lamp, and an external speaker are installed in the canopy 3.

[0055] A multi-rod intelligent sampling system includes a sampling system, a sample conveying system and a control and operating system; the sampling system includes a multi-rod intelligent sampling machine; the sample conveying system consists of a Roots blower, a conveying pipeline, a control box and other parts, and is used for conveying and storing grain samples; the control and operating system consists of a control cabinet, an operating table, a display and other parts, and is used for operating and controlling the sampling machine.

[0056] In this embodiment, the system utilizes a multi-rod intelligent sampler to simultaneously collect samples from multiple locations, significantly improving sampling efficiency and accuracy while saving manpower and time. Through an integrated control and operating system, users can conveniently control the sampler's operating status via the console and display. Automated control significantly reduces human error and improves the consistency and reliability of sample collection. The multi-rod intelligent sampler can sample at different heights and positions according to pre-set procedures, ensuring sample representativeness and uniformity, and avoiding the potential bias associated with manual sampling. The sample transport system utilizes a Roots blower and conveying pipelines to rapidly transport samples to a storage area, ensuring sample integrity and safety during transport. This system not only reduces human intervention but also mitigates the risk of cross-contamination. The system's high degree of automation significantly minimizes manual intervention, requiring operators to perform simple system monitoring and maintenance, significantly reducing labor intensity. The control and operating system integrates data acquisition and real-time monitoring capabilities, allowing users to view all sampling data in real time, ensuring traceability and transparency throughout the entire process. The multi-rod intelligent sampler can be flexibly adjusted to suit different materials and sampling requirements, adapting to a variety of scenarios and ensuring accurate collection of different types of samples. Overall, this multi-rod intelligent sampling system integrates advanced technologies and combines automation, precision control and efficient operation to not only improve sampling accuracy and efficiency, but also ensure sample quality and reduce operational difficulty and risks.

[0057] The laboratory can use the existing laboratory without changing its location. The newly added grain discharging system of the sampling machine does not occupy a large area and is located at the wall hole where the original sampling grain pipe enters the laboratory. Equipment such as the automatic mixing and discharging device are supported by a frame. An inclined pipe and a diversion pipe can be installed under the grain collecting hopper of the grain discharging system. The samples discharged from the diversion pipe can be used for testing. Excess samples are discharged to the outside of the laboratory through the wall. A dust removal box is installed at the outlet of the pipe. There are exhaust holes on the dust removal box that are connected to the outside through the hole in the wall. An exhaust fan is installed on the exhaust hole. The function of the dust removal box is to suck the floating dust generated when the grain sample is discharged to the outside to maintain a sanitary environment indoors. The operation room is located near the storage entrance, and an operation table and control cabinet are installed indoors. Before installing the equipment, it is necessary to connect a power cable that meets the requirements above in the operation room.

[0058] Specifically, the cover system is mainly used in grain storage and grain processing enterprises. It can replace manual operations in the process of grain sampling and transmission to the laboratory, realize automatic and closed grain sampling and transmission, and physically isolate quality inspectors from information contact with grain trucks, avoiding interference and influence of human factors on grain quality inspection and evaluation.

[0059] The intelligent grain sampling machine is controlled by embedded software and uses computer technology to organize and calculate data, so that the sampling stick can randomly select points within the sampling range to draw samples. From a technical perspective, it truly realizes the comprehensiveness and randomness of sampling, ensures the authenticity and representativeness of the grain sample testing results, and greatly meets the needs of customers.

[0060] Once preparations are complete, the device automatically begins sampling with the click of a button. The sampling machine automatically identifies the vehicle type and determines the sampling range. The program automatically selects the appropriate sampling area and randomly calculates the sampling location, achieving uniform, blind-spot-free, and irregular sampling. The automatic grain sampling machine eliminates manual sampling location selection and blind-spot setting, and supports remote monitoring of the sampling control process.

[0061] Working principle: By driving the packaged grain on board and the uncovered bulk grain truck into the canopy 3, sampling and testing can be carried out through the sampling mechanism 5, and grain sampling can be carried out simultaneously by multiple sampling mechanisms 5, thereby significantly improving the sampling efficiency and accuracy. In large-volume transport vehicles, multiple sampling mechanisms 5 can cover the entire grain storage area more comprehensively, ensuring that each area can be effectively sampled. Through the combination of the moving mechanism 6 and the adjusting mechanism 7, the sampling mechanism 5 can not only move laterally, but also be adjusted longitudinally, which enables the equipment to adapt to grain trucks of different types and sizes. Regardless of the distribution height of the grain in the vehicle or the different sizes of the carriages, the sampling position can be flexibly adjusted to achieve automatic adjustment and operation, which not only reduces the burden of manual operation, but also improves the safety and accuracy of the operation. Operators can conveniently operate multiple mechanisms through a simple control panel or remote control device. The combination of multiple adjustment mechanisms 7 and moving mechanisms 6 enables the system to quickly and flexibly complete sampling tasks in different areas, reducing the necessity of manual intervention, thereby improving the overall efficiency of the operation, solving the limitations of traditional equipment on large-volume grain transport vehicles, and performing outstandingly in improving operational efficiency, accuracy, safety and ease of operation. Through intelligent and automated technologies, the sampling process is optimized, and it has broad application prospects.
