Description

Technical Field

[0001] This utility model relates to the field of flue-cured tobacco technology, specifically to a weighing device for flue-cured tobacco leaves. Background Technology

[0002] Flue-cured tobacco is an important economic crop in my country, with an annual planting area exceeding 1 million hectares. The curing process is a crucial step in tobacco production. During curing, the change in moisture content of the tobacco leaves is a key indicator for determining the weight of the cured leaves, and it is used to statistically analyze the quantity and quality of cured tobacco leaves in the production area.

[0003] In existing technologies, tobacco leaves are typically weighed before and after baking, which makes it impossible to accurately calculate the fresh-to-dry ratio and to accurately measure the yield of tobacco-growing areas. Utility Model Content

Detailed Implementation

[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0019] Please see Figures 1-4 This utility model provides a tobacco leaf weighing device for flue-cured tobacco, including a curing chamber. The curing chamber is equipped with a curing rack, a humidity sensor, a temperature sensor, and a control module. The curing rack includes a vertical support frame and a horizontal placement frame. The placement frame includes a lower rod and an upper rod. The upper rod is fixedly mounted on the vertical frame, and the lower rod is connected to the upper rod via a connecting rod. A gap is left between the upper and lower rods for placing tobacco leaf stalks. A tension sensor is installed on the connecting rod. The humidity sensor, temperature sensor, and tension sensor are electrically connected to the control module. During tobacco leaf curing, the device automatically records the weight of fresh tobacco leaves, the weight of tobacco leaves after curing, and the weight change caused by moisture changes during the curing process, using the temperature and humidity sensors. When fresh tobacco leaves are loaded into the curing chamber, the tobacco leaf stalks are placed on a weighing device below the loading rack. The device automatically records the weight change, the number of stalks loaded, and the final weight of fresh tobacco leaves in the full curing chamber. The same applies when the tobacco leaves are removed from the curing chamber initially. Simultaneously, the device automatically records the weight changes throughout the entire curing process. Moisture changes during tobacco curing are a crucial indicator for determining the weight of cured tobacco leaves. The curing chamber is multi-sectioned, and the racks have multiple layers, allowing for simultaneous curing of multiple layers of tobacco leaves. Tension sensors are installed on the connecting rods; the deformation of the connecting rods as the weight of the tobacco leaves changes is recorded by the tension sensors, and the weight of the tobacco leaves is then calculated.

[0020] As a further improvement to the above technical solution, multiple placement racks are provided, each with an individual tension sensor on each connecting rod, and each support frame is equipped with both a humidity sensor and a tension sensor. The tension sensor on each connecting rod facilitates real-time measurement of the weight changes of the tobacco leaves on each placement rack, thereby recording the changes in moisture and weight of the tobacco leaves during the curing process. This allows for accurate calculation of the weight of fresh tobacco leaves per rack, the weight of dried tobacco leaves per rack after curing, and the total weight before and after curing, based on the loading and unloading sequence. This precise calculation of the fresh-to-dry ratio provides data support for selecting curing strategies in tobacco-growing areas.

[0021] As a further improvement to the above technical solution, the tobacco stem is configured as a cylindrical rod, and the lower rod has a plurality of grooves arranged sequentially along its length for placing the tobacco stem. The grooves prevent the tobacco stem from sliding during the roasting process, as it is placed within them. The cylindrical shape of the tobacco stem allows it to slide and adjust its position on the lower rod. Preferably, rotatable stops are also provided at both ends of the tobacco stem. These stops restrict the left and right movement of the tobacco stem on the lower rod, preventing it from falling off. The rotatable stops facilitate the placement of the tobacco stem into the gaps.

[0022] As a further improvement to the above technical solution, the groove is set in an arc shape, the diameter of the groove is the same as the diameter of the tobacco stem, and the height of the groove is no greater than half the radius of the tobacco stem. Setting the groove in an arc shape while limiting its height allows the tobacco stems to be pushed during the tobacco leaf placement process, thus placing them in the appropriate position. Preferably, a pressure sensor is installed inside the groove, and the number of tobacco stems loaded is counted and recorded based on the data obtained from the pressure sensor.

[0023] As a further improvement to the above technical solution, a data transmission module is also included. This data transmission module is electrically connected to the control module and is used to transmit data acquired by the humidity sensor, temperature sensor, and tension sensor to the cloud platform. The data transmission module transmits the data from each tobacco curing operation to the cloud platform for statistical analysis, providing data support for selecting curing strategies in tobacco-growing areas; it also performs post-curing dry tobacco leaf weight statistics, facilitating accurate yield measurement in tobacco-growing areas and changing the previous reliance on manual statistics.

[0024] As a further improvement to the above technical solution, a data analysis module and a storage module are also included. The storage module is electrically connected to the control module and is used to store data acquired by humidity sensors, temperature sensors, and tension sensors. The data analysis module is used to analyze the acquired data. The data analysis module statistically analyzes the tobacco curing data and the changes in tobacco moisture content during the curing process throughout the county, and generates a tobacco moisture content change curve for comparison in different regions, serving as an important indicator for judging the tobacco curing curve. The change in moisture content during the tobacco curing process is a crucial indicator for determining the weight of cured tobacco leaves. Relevant data is automatically transmitted to the cloud platform via the data transmission module, facilitating the statistical analysis of the quantity and quality of cured tobacco leaves throughout the county.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
