Description

Technical Field

[0001] This utility model relates to the technical field of tobacco leaf baling equipment, specifically to a tobacco leaf baling machine with automatic weighing. Background Technology

[0002] After initial sorting following curing, tobacco leaves need to be bundled for storage and transportation. Most tobacco farmers use tobacco baling machines, which involve placing a certain quantity of leaves of the same grade into the baling machine's loading box for bundling. Initial sorting after curing is a crucial step in ensuring accurate yield measurement, improving procurement efficiency, and standardizing procurement procedures. Accurately understanding the farmers' initial sorting situation is vital for predicting procurement volume, arranging procurement work in advance, and managing procurement procedures effectively. Currently, the accuracy of tobacco yield measurement in the city is not high, leading to problems such as delayed procurement arrangements, uncertain contract adjustments, and inaccurate management. For example, inaccurate predictions of the procurement completion rate put pressure on higher-level decision-making; the inability to promptly apply for contract increases or decreases can lead to delayed procurement and potential procurement conflicts; and the possibility of cross-border loss or inflow of cured tobacco leaves from farmers remains a concern, hindering the standardized management of procurement procedures. Earlier and more accurate yield measurement leads to more timely and stable procurement. Therefore, we are improving the accuracy of yield measurement by implementing a bundling and counting project.

[0003] Tobacco yield measurement mainly consists of three parts: the amount of unharvested flue-cured tobacco leaves, the amount of tobacco leaves initially sorted after curing, and the amount already sold. The amount already sold is 100% accurate, but the data has a lag; the prediction of the amount of unharvested flue-cured tobacco leaves is predictive, but it mainly relies on experience and is not very accurate; currently, tobacco balers usually do not have electronic scales installed, and the compaction of tobacco leaves during baling is mainly done manually, resulting in the amount of tobacco leaves initially sorted after curing being generally estimated and reported arbitrarily by tobacco farmers, which is highly arbitrary. Therefore, we need to accurately control the initial amount of tobacco leaves after curing to improve the accuracy of yield measurement, while also better addressing the high labor intensity of baling. Utility Model Content

[0004] The purpose of this utility model is to provide a tobacco baling machine with automatic weighing, which solves the problem that existing baling machines cannot automatically weigh the initial weight of tobacco leaves after curing, and cannot accurately control the initial weight of tobacco leaves after curing.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tobacco baling machine with automatic weighing, comprising a cubic loading frame with an open top, a power supply, an electronic scale, and a lifting cylinder. The loading frame is equipped with surrounding plates, and a matching movable partition is movably disposed within the upper part of the loading frame. The downward movement of the movable partition is limited to the middle of the loading frame. The lifting cylinder is fixedly disposed within the lower part of the loading frame. A rectangular lifting plate matching the inner frame of the loading frame is provided at the upper end of the lifting cylinder. A support column is provided on the lifting plate, passing through the movable partition. An upper pressure plate is connected to the top of the support column, and the upper pressure plate matches the inner frame of the loading frame. Under the drive of the support column, the upper pressure plate moves up and down within the inner frame of the loading frame. The lifting plate is disposed below the movable partition, and the electronic scale is placed in the middle position of the lifting plate. The power supply provides power to the electronic scale.

[0006] By adopting the above technical solution, the lifting cylinder is first activated to raise the lifting plate, the upper pressure plate, and the electronic scale on the lifting plate to a certain position. When the electronic scale contacts the movable partition, leaving a large space between the upper pressure plate and the tobacco loading frame, the tobacco leaves that need to be bundled after initial sorting are placed from the space between the upper pressure plate and the tobacco loading frame onto the movable partition inside the tobacco loading frame. After loading the appropriate amount of tobacco leaves, the electronic scale obtains the weighing information of the tobacco leaves. Then, the lifting cylinder is activated to lower the movable partition. The electronic platform scale and the upper pressure plate descend together. When the movable partition moves to the middle of the tobacco loading frame, the movable partition stops in the middle of the tobacco loading frame and stops descending, while the electronic platform scale and the upper pressure plate continue to descend. During this process, the descending upper pressure plate presses down on the tobacco leaves that need to be bundled after initial separation and are placed on the movable partition of the tobacco loading frame. At this time, the electronic platform scale is also completely separated from the movable partition, and the lifting cylinder stops. The bottom of the movable partition is fully engaged in the middle of the tobacco loading frame, and then the two ends of the binding rope are tied from above.

[0007] The above technical solution utilizes the lifting cylinder to weigh the tobacco leaves when they are in the rising position and to compact them during the descending process, which facilitates bundling. On the one hand, it solves the problem of accurately controlling the initial weight of the tobacco leaves after curing and weighing them in a timely manner. On the other hand, the lifting cylinder solves the problem of the time-consuming and labor-intensive nature of the original manual compaction and bundling.

[0008] Furthermore, the surrounding plate and the movable partition are provided with grooves for placing binding ropes on their upper surfaces. The purpose of setting the grooves is to better regulate the placement of binding ropes.

[0009] Furthermore, the lowest point of the groove is at the same level as the upper end of the movable partition when it moves to its lowest limit, thus ensuring that the binding rope can make better contact with the tobacco leaves.

[0010] In addition, to achieve automatic uploading of weighing information, this type of tobacco baling machine with automatic weighing is limited to include an electronic platform scale wireless intelligent auxiliary terminal system, a control panel, and a QuickBI digital display board. The power supply provides power to the electronic platform scale and the wireless intelligent auxiliary terminal system. The control panel is located on the outer surface of the surrounding plate and controls the start and stop of the lifting cylinder. The electronic platform scale wireless intelligent auxiliary terminal system records the weighing data of the electronic platform scale and transmits it to the QuickBI digital display board.

[0011] Using the above technical solution, firstly, the lifting cylinder is activated to raise the electronic platform scale until it contacts the movable partition, at which point the raising stops. At this point, the movable partition is fully engaged with the electronic platform scale, which can weigh the tobacco leaves placed on the movable partition. Then, the binding rope is placed in the wire groove, and the tobacco leaves that need to be bundled after initial sorting are placed on the movable partition inside the tobacco loading frame. After loading the appropriate amount of tobacco leaves, the electronic platform scale obtains the weighing information of the tobacco leaves and transmits it to the QuickBI digital dashboard through the wireless intelligent auxiliary terminal system, dynamically displaying the tobacco leaf bundling count. After the electronic platform scale receives feedback from the wireless intelligent auxiliary terminal system, the lifting cylinder is activated to lower the scale, and the movable partition and the electronic platform scale descend together. When the movable partition reaches the middle of the tobacco loading frame, it stops descending, while the electronic platform scale continues to descend. The lifting cylinder stops after the electronic platform scale is completely separated from the movable partition. Typically, a limiting block is installed in the middle of the tobacco loading frame. This limiting block prevents the movable partition from continuing to descend. This limiting block can be placed at the four corners of the tobacco loading frame or the inner edge of an angle iron, as long as it effectively prevents the movable partition from descending further. When the movable partition moves to the middle of the tobacco loading frame, its bottom fully engages with the limiting block in the middle of the frame. Then, the ends of the binding rope are tied together from above.

[0012] Using IoT devices, tobacco farmers standardize and bundle the initial sorted tobacco leaves after curing, and the weighing data is automatically uploaded. A digital yield measurement model is constructed based on factors such as the sales volume to calculate the expected quantity and proportion of tobacco leaves to be completed by farmers. The uploaded quantity is used as the curing quantity for the scheduled delivery stage. The system issues warnings for weighing data, time, and frequency; if abnormal values ​​are exceeded, tobacco technicians are notified to conduct on-site inspections to prevent tobacco leaves from flowing out or into the area. The accurate calculation of the ratio of sales volume to weighing volume serves as a basis for evaluating the quality of the initial sorting of tobacco leaves by farmers and the performance of tobacco technicians.

[0013] These measures enable precise control over the quantity of tobacco leaves delivered, accurate monitoring of tobacco leaf movements, and precise inspection of tobacco leaf quality.

[0014] The electronic platform scale wireless intelligent auxiliary terminal system further specifies that it includes a main control computer connected to a wireless communication module; the electronic platform scale is equipped with a wireless intelligent auxiliary terminal, the hardware of which consists of an MCU and a wireless communication module connected to the MCU, an electronic platform scale communication module, and a display module; both the main control computer and the wireless communication module of the electronic platform scale include a self-organizing Zigbee module and an RS232 conversion circuit.

[0015] This type of wireless intelligent auxiliary terminal system for electronic platform scales is a mature existing technology, such as the "Wireless Intelligent Auxiliary Terminal System for Electronic Platform Scales" disclosed in Chinese Invention Patent CN103528655B. This technical solution can directly utilize the most basic weighing and wireless transmission functions of such systems to realize information exchange between the wireless intelligent auxiliary terminal and the electronic platform scale. After level conversion by the RS232 conversion circuit, the main control computer is connected to the Zigbee module of the wireless communication module to realize information exchange between the wireless communication module and the main control computer. The wireless communication module of the main control computer and each wireless intelligent auxiliary terminal of each other electronic platform scale form a wireless local area network, which is responsible for transmitting weighing results and related control command information. The electronic scale communication module is connected to the electronic platform scale on site through wired serial communication, so that the wireless intelligent auxiliary terminal can receive the weighing information of the electronic platform scale in real time, so that the wireless intelligent auxiliary terminal can make timely and accurate judgments on the correctness of the weighing results.

[0016] Furthermore, this utility model further specifies that the QuickBI digital dashboard is used for data analysis and display. The digital dashboard interface is simple, rich in content, and provides real-time alerts. The QuickBI digital dashboard provides an alert function, automatically listing tobacco farmers who are behind in the sales progress (20%), as well as those with abnormal tobacco bales. This improves the level of digital management. It dynamically displays the tobacco leaf baling count, and is designed to meet the different needs of three levels: decision-making (leaders), management (departments), and business (teachers). The content includes overall situation, site baling count, and baling count in the area of ​​each tobacco technician (down to the farmer level). It also includes a farmer alert function, promptly alerting tobacco technicians to farmers with lagging sales progress or poor initial sorting quality, enabling timely on-site guidance and inspection.

[0017] The above technical solution can ensure that the electronic platform scale obtains the weighing information of the tobacco leaves, and then transmits the weighing information of the tobacco leaves to the QuickBI digital dashboard through the wireless intelligent auxiliary terminal system to dynamically display the counting of tobacco leaf bundles. On the other hand, it can also use the lifting cylinder and the upper pressure plate to compact the tobacco leaves, ensuring that the bundled tobacco leaves are not loose and reducing the time-consuming and labor-intensive defects of manual compaction and bundling.

[0023] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Example

[0024] like Figure 1-3 As shown, a tobacco baling machine with automatic weighing includes a cubic loading frame with an open top, a power supply, an electronic scale 3, and a lifting cylinder 5. The loading frame is surrounded by peripheral plates 1. A matching movable partition 2 is movably installed inside the upper part of the loading frame, and the downward movement of the movable partition 2 is limited to the middle of the loading frame, i.e., a limiting block 11 is provided in the middle of the loading frame. The lifting cylinder 5 is fixedly installed inside the lower part of the loading frame. A rectangular lifting plate 4 matching the inner frame of the loading frame is provided at the upper end of the lifting cylinder 5. A support column 41 is provided on the lifting plate 4. The column passes through the movable partition 2, and the top of the support column 41 is connected to the upper pressure plate 42. The upper pressure plate 42 matches the inner frame of the cigarette loading frame. Under the drive of the support column 41, the upper pressure plate 42 moves up and down in the inner frame of the cigarette loading frame. The lifting plate 4 is located below the movable partition 2, and the electronic scale 3 is placed in the middle position of the lifting plate 4. The power supply provides power to the electronic scale 3. The upper surface of the surrounding plate and the movable partition is provided with a wire groove 12 for placing the binding rope. The lowest point of the wire groove 12 is at the same level as the upper end of the movable partition 2 when it moves to the lowest limit. Example

[0025] like Figure 1-5As shown, a tobacco baling machine with automatic weighing includes a cubic loading frame with an opening at the top. A surrounding plate 1 is fitted around the loading frame. A matching movable partition 2 is movably disposed within the upper part of the loading frame. A limiting block 11 is provided in the middle of the loading frame. A lifting cylinder 5 is fixedly disposed within the lower part of the loading frame. The downward movement of the movable partition 2 is limited by the limiting block 11. A groove 12 for placing baling ropes is provided on the upper surfaces of the surrounding plate 1 and the movable partition 3. The machine also includes an electronic scale 3, a power supply, a control panel 13, an electronic scale wireless intelligent auxiliary terminal system, and a QuickBI digital display board. The electronic scale 3 is disposed below the movable partition 2. The lower end of the electronic scale is provided with the lifting cylinder 5, and the upper end of the lifting cylinder 5 is provided with a rectangular lifting plate. 4. Support columns 41 are provided at the four corners of the lifting plate 4. The support columns 41 pass through the movable partition 2. The top of the support column 41 is connected to the upper pressure plate 42. The upper pressure plate 42 matches the inner frame of the smoke loading frame. Under the drive of the support columns 41, the upper pressure plate 42 moves up and down in the inner frame of the smoke loading frame. The electronic platform scale 3 is placed in the middle position of the lifting plate 4. The lifting cylinder 5 pushes the electronic platform scale 3 to move up and down. The power supply provides power to the electronic platform scale 3 and the wireless intelligent auxiliary terminal system. The control panel 13 is set on the outer surface of the surrounding plate 1. The control panel 13 controls the start and stop of the lifting cylinder 5. The wireless intelligent auxiliary terminal system of the electronic platform scale records the weighing data of the electronic platform scale 3 and transmits it to the QuickBI digital dashboard.

[0026] By adopting the above technical solution, the lifting cylinder 5 is first activated to rise, which in turn raises the lifting plate 4, the upper pressure plate 42, and the electronic scale 3 on the lifting plate to a certain position. When the electronic scale 3 contacts the movable partition 2, and there is a large space between the upper pressure plate 42 and the tobacco loading frame, the binding rope is placed in the wire groove 12. Then, the tobacco leaves that need to be bundled after initial sorting are placed from the space between the upper pressure plate 42 and the tobacco loading frame onto the movable partition 2 inside the tobacco loading frame. After loading the appropriate amount of tobacco leaves, the electronic scale 3 obtains the weighing information of the tobacco leaves. Then, the weighing information of the tobacco leaves is transmitted to the QuickBI digital dashboard through the wireless intelligent auxiliary terminal system, dynamically displaying the tobacco leaf bundling count. Once the electronic platform scale 3 receives feedback from the wireless intelligent auxiliary terminal system, it activates the lifting cylinder 5 to descend. The movable partition 2, the electronic platform scale 3, and the upper pressure plate 42 descend together. When the movable partition 2 moves to the middle of the tobacco loading frame, it stops at the limit block 11 in the middle of the tobacco loading frame and stops descending. Meanwhile, the electronic platform scale 3 and the upper pressure plate 42 continue to descend. The descending upper pressure plate 42 presses down the tobacco leaves that need to be bundled after initial separation and are placed on the movable partition of the tobacco loading frame. At this time, the electronic platform scale 3 is completely separated from the movable partition 2, and the lifting cylinder stops. The bottom of the movable partition 2 is fully engaged in the middle of the tobacco loading frame, and then the two ends of the binding rope are tied from above.

[0027] The electronic platform scale wireless intelligent auxiliary terminal system includes a main control computer 10, which is connected to a wireless communication module 40; the electronic platform scale 3 is equipped with a wireless intelligent auxiliary terminal 30, the hardware of which consists of an MCU and a wireless communication module 40 connected to the MCU, an electronic scale communication module 33, and a display module 34; both the main control computer 10 and the wireless communication module 40 of the electronic platform scale 3 include a self-organizing Zigbee module and an RS232 conversion circuit.

[0028] This technical solution directly utilizes the most basic weighing and wireless transmission functions of such systems to achieve information exchange between the wireless intelligent auxiliary terminal and the electronic platform scale. The main control computer, after level conversion via an RS232 conversion circuit, connects to the Zigbee module of the wireless communication module, enabling information exchange between the wireless communication module and the main control computer. The wireless communication module of the main control computer, together with each wireless intelligent auxiliary terminal of each other electronic platform scale, forms a wireless local area network responsible for transmitting weighing results and related control commands. The electronic scale communication module connects to the electronic platform scale on-site via wired serial communication, allowing the wireless intelligent auxiliary terminal to receive weighing information from the electronic platform scale in real time, enabling the wireless intelligent auxiliary terminal to make timely and accurate judgments on the correctness of the weighing results.

[0029] In this technical solution, the QuickBI digital dashboard stores tobacco farmers' baling data for analysis and display. The dashboard interface is simple, content-rich, and provides real-time alerts. The QuickBI digital dashboard offers an alert function, automatically listing tobacco farmers whose sales progress is lagging behind by the last 20%, as well as those with abnormal tobacco bales. This improves the level of digital management. It dynamically displays the tobacco leaf baling count, and is designed to meet the different needs of three levels: decision-making (leaders), management (departments), and operational (teachers). The content includes overall status, site baling count, and baling count for each tobacco technician's area (down to the farmer level). An alert function for farmers is also designed, promptly alerting tobacco technicians to farmers with lagging sales progress or poor initial sorting quality, allowing for timely on-site guidance and inspection.

[0030] Initial data is collected by tobacco balers distributed to farmers, gathering weight information during baling and uploading it in batches to the manufacturer's external server. The manufacturer's external server receives and stores the corresponding balers and their IDs. The internal baling application server periodically accesses the manufacturer's server to retrieve baling data. Once the data is retrieved and entered into the internal network, the server maps the device IDs to the registered farmer information and stores it in the baling analysis database. This data is then provided to QuickBI's digital dashboard and streamlined workflows.

[0031] This project addresses the difficulties and bottlenecks in tobacco yield measurement by using digital applications to solve problems such as low accuracy in yield measurement, inaccurate data acquisition, imprecise standardized management of tobacco leaves, and extensive and incomplete assessment. It improves the management level of the procurement work and has extremely high promotion value in tobacco-producing areas throughout the city.

[0032] Through digital transformation applications, the tobacco leaf baling and counting project has achieved three major results:

[0033] (a) Precise control of tobacco leaf quantity

[0034] By accurately weighing the initial sorted tobacco leaves and combining this with a data model, yield can be measured in a timely manner according to tobacco farmers' contracts. As the procurement progresses, the accuracy of yield measurement will further improve, and it is expected that the accuracy will increase from 93% to 98%, an increase of 5 percentage points. Timely prediction of procurement volume lays a solid foundation for the overall planning of procurement work.

[0035] (II) Precise monitoring of tobacco leaf movement

[0036] The actual process of tobacco production is from harvesting and curing to re-moistening, initial sorting, bundling, weighing, and storage for sale. By digitally recording the weighing process, including information such as the weight of a single bundle, weighing frequency, number of bundles per room, and weighing time, combined with the actual situation, it is possible to comprehensively judge whether the weighing of tobacco leaves is normal and whether there is any outflow or inflow of tobacco leaves. This provides an important basis for accurately monitoring the movement of tobacco leaves and ensuring the order of procurement.

[0037] (III) Precise inspection of tobacco leaf quality

[0038] By collecting baling and counting data, weaknesses can be identified through digital analysis. For example, by analyzing the ratio of tobacco farmers' delivered quantity to weighed quantity, the initial sorting and curing quality can be assessed, allowing for the timely identification of farmers requiring further guidance in initial sorting or curing, and serving as a basis for farmer star rating. Furthermore, analyzing the accuracy of yield measurement and initial sorting quality in the areas measured by tobacco technicians can serve as a basis for their performance evaluation, solving the problem of incomplete and inaccurate assessments caused by previous random checks.

[0039] The above technical solution can ensure that the electronic platform scale obtains the weighing information of the tobacco leaves, and then transmits the weighing information of the tobacco leaves to the QuickBI digital dashboard through the wireless intelligent auxiliary terminal system to dynamically display the counting of tobacco leaf bundles. On the other hand, it can also use the lifting cylinder and the upper pressure plate to compact the tobacco leaves, ensuring that the bundled tobacco leaves are not loose and reducing the time-consuming and labor-intensive defects of manual compaction and bundling.

[0040] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
