Description

Technical Field

[0001] This utility model relates to a tobacco plant ranging and leaf-cutting and stem-retaining device, belonging to the technical field of tobacco plant topping. Background Technology

[0002] Topping of flue-cured tobacco refers to removing the flower buds or inflorescences of the tobacco plant at an appropriate time to eliminate apical dominance and promote the opening of the upper second leaf, which plays an important role in the formation of tobacco leaf quality. Slanting the stem to leave 10-20cm is one of the mainstream techniques for topping flue-cured tobacco. This technique disrupts the synchronous germination of axillary buds at various nodes of the stem, concentrating nutrients to supply the top 1-2 axillary buds and inhibiting the activation of lower axillary buds. Simultaneously, the slanted cut allows for drainage and prevents bacteria, reducing the risk of red spot disease and empty stem disease. However, current slanted topping techniques rely on visual estimation by the operator to control the stem height, resulting in large length deviations and making standardization difficult. Utility Model Content

[0003] Based on the above, this utility model provides a method for measuring the distance of tobacco plants, removing leaves and retaining stems, to overcome the shortcomings of the prior art.

[0004] The technical solution of this utility model is: a tobacco plant ranging, leaf-cutting, and stem-retaining device, comprising:

[0005] A cutting unit includes a housing, a blade, and a drive mechanism. The housing is elongated and has a notch. The blade is movably disposed on one side of the notch, and the drive mechanism can drive the blade to extend or retract.

[0006] The ranging unit includes a scale and an indicator sleeve disposed on the scale and capable of sliding along the scale axis. The back of the indicator sleeve is mounted on the housing, such that the axis of the scale has a predetermined angle with the plane of the blade.

[0007] In one example, a handle is provided at the bottom of one end of the housing, and a control handle is provided on the housing in front of the handle. The control handle is electrically connected to a controller, and the controller is electrically connected to the drive mechanism.

[0008] In one example, the drive mechanism is an electric telescopic rod, and the housing has an accommodating space for mounting the electric telescopic rod.

[0009] In one example, the housing is provided with a groove, and a slider is provided in the groove. The slider's direction of movement is set to be the same as the extension and retraction direction of the blade, and the indicator sleeve is mounted on the slider.

[0010] In one example, the side of the indicator sleeve is provided with an ear plate, which is connected to the slider and the housing by an adjusting bolt.

[0011] In one example, the indicator sleeve is a flat box shape, and a fastening bolt is provided on the indicator sleeve, through which the scale is fixed to the indicator sleeve.

[0012] The beneficial effects of this invention are as follows: By coordinating the ranging unit and the cutting unit, the problem of inaccurate stem height in traditional topping operations is solved. Using a vernier caliper-type ranging unit (scale + sliding indicator sleeve), the stem height can be accurately set to three levels: 10cm, 15cm, and 20cm. The angle between the scale axis and the blade plane can be adjusted by rotating the ear plate and adjusting bolt. The indicator sleeve, linked to the slider, can slide along the blade's extension and retraction direction, adapting to ranging operations with different stem diameters. Attached Figure Description

[0020] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] Please see Figures 1 to 4 This embodiment provides a tobacco plant ranging and leaf-cutting / stem-retaining device, which includes a cutting unit and a ranging unit.

[0022] The cutting unit includes a housing 11, a blade 12, and a drive mechanism 13. The housing 11 is elongated and has a notch 14 to accommodate tobacco stems. The blade 12 is movably mounted on one side of the notch 14. The drive mechanism 13 is an electric telescopic rod. The housing 11 has a space for mounting the electric telescopic rod. The free end of the electric telescopic rod is connected to the blade 12, so that the drive mechanism 13 can drive the blade 12 to extend and retract. When extended, the blade can cut the tobacco stem located in the notch 14.

[0023] For ease of operation, a handle 15 is installed at the bottom of one end of the housing 11. A control handle 16 is located on the housing 11 in front of the handle 15. The control handle 16 is electrically connected to the controller, which is in turn electrically connected to the drive mechanism 13. During use, the handle 15 can be held. When the cutting action needs to be controlled, the control handle 16 can be pulled. The rotation of the control handle 16 generates a signal, which is transmitted to the controller. The controller then controls the drive mechanism 13 to perform the cutting action. The structure of the control handle 16 is similar to that of a water gun or toy pistol, and will not be described in detail here.

[0024] The measuring unit includes a scale 21 and an indicator sleeve 22 mounted on the scale 21 and capable of sliding along its axial direction. The back of the indicator sleeve 22 is mounted on the housing 11, such that the axial direction of the scale 21 has a predetermined angle with the plane of the blade 12, for example, 45°, 90°, or other angles. The zero value of the scale 21 is located at its lower end; in this embodiment, the scale value is not shown. The indicator sleeve 22 is a flat box shape, and a fastening bolt 23 is mounted on it. The scale 21 is fixed to the indicator sleeve 22 by the fastening bolt 23. Thus, during cutting, the positions of the indicator sleeve 22 and the scale 21 can be adjusted first, and then the topping height can be ensured by the scale 21 and the indicator sleeve 22, ensuring that a standard length of stem is left after the tobacco is topped, thus ensuring uniform growth of the tobacco plants.

[0025] For ease of operation, a groove 24 is provided on the housing 11, and a slider 25 is installed in the groove 24. The slider 25 moves in the same direction as the extension and retraction direction of the blade 12, and an indicator sleeve 22 is installed on the slider 25. This allows the position of the indicator sleeve 22 to be adjusted as needed, such as its distance from the stem and tobacco leaves.

[0026] For ease of operation, an ear plate 26 is fixed on the side of the indicator sleeve 22. The ear plate 26 is connected to the slider 25 and the housing 11 by adjusting bolt 27. When it is necessary to adjust the angle between the scale 21 and the blade 12, the adjusting bolt 27 can be loosened first, then the ear plate 26 can be rotated at a certain angle, and finally the adjusting bolt 27 can be tightened.

[0027] The working principle of the above-mentioned tobacco plant distance measurement, leaf removal, and stem retention:

[0028] Holding handle 15, first adjust the length of scale 21 relative to indicator sleeve 22, i.e. the stem length to be retained, and adjust scale 21 to a suitable position and tilt angle, such as 45°, by adjusting bolt 27. Measure the stem length to be retained according to scale 21, and align notch 14 with the position of the tobacco plant to be topped and put it over the stem. Then pull control handle 16, drive mechanism 13 drives blade 12 to extend and cut the tobacco stem, and then retracts back into housing 11. After completion, sliding plate retracts back into housing 11.

[0029] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
