Description

Technical Field

[0001] The utility model relates to the technical field of tobacco utensils, and more particularly to a tobacco plant leaf measuring tool. Background Art

[0002] During the growth of flue-cured tobacco, in order to investigate the growth of tobacco and judge the quality of tobacco leaves in advance, it is necessary to analyze the botanical characteristics of tobacco plants, such as Figure 1 The tobacco plant stem-leaf angle α (also known as the leaf inclination angle), tobacco leaf size (including leaf length H1, leaf height H2) and other physical parameters are measured. At present, when testing the botanical characteristics of flue-cured tobacco, it is necessary to carry a variety of tools such as rulers and protractors at the same time, and the measuring tools need to be constantly replaced during the measurement process. Not only is the operation cumbersome and the workload large, but it is also time-consuming. In the prior art, image analysis and processing methods are used to measure the length of plant leaves, such as CN202770762U-Plant Leaf Change Monitoring Device. This equipment has high investment and high use requirements, and it is difficult to promote it to grassroots farms on a large scale.

[0003] Among length, angle and height measuring tools, digital rulers have been widely used by surveyors because they can display measurement values ​​in real time and are easy to use, such as digital calipers, digital height rulers, digital angle rulers, etc.

[0004] A digital caliper (such as CN208688352U) is a measuring tool used to measure length, inside and outside diameters, and depth. It consists of a ruler, a scale frame, and a digital display. The scale frame slides onto the ruler, and the digital display is mounted on the scale frame. By moving the scale frame, the measured value is displayed in real time on the digital display.

[0005] A digital height gauge (such as CN218179804U - a new type of digital height gauge) is mainly composed of three parts: a scale body, a scale frame, and a digital display assembly. The scale frame is slidably connected to the scale body, and the digital display assembly is set on the scale frame. By moving the scale frame, the measured value is displayed in real time on the digital display assembly.

[0006] A digital angle ruler (such as CN218002424U-digital angle ruler) is mainly composed of a main scale (fixed scale), a secondary scale (movable scale), and a digital display component. The main scale and the secondary scale are hinged. When the secondary scale is rotated, the digital display component on the secondary scale displays the measured angle value in real time.

[0007] After searching, it was found that in the prior art, digital calipers, digital height gauges, and digital angle gauges have not been integrated and applied to the measurement of the length and height of tobacco leaves and the angle of tobacco stems and leaves.

[0008] Therefore, in order to fill the technical gap in this area, the applicant proposed a tobacco leaf measuring tool that integrates a digital caliper, a digital height gauge, and a digital angle gauge. This measuring tool can intuitively display the measurement results and is low in cost, making it more suitable for large-scale promotion to grassroots tobacco farms. Utility Model Content

[0009] In view of this, the utility model provides a tobacco leaf measuring tool that integrates a digital caliper, a digital height gauge, and a digital angle gauge. The measuring tool can intuitively display the measurement results and has low cost, making it more suitable for large-scale promotion to grassroots tobacco farms.

[0010] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0011] A tobacco plant leaf measuring tool, comprising:

[0012] An outer shell, wherein a top surface and a side surface of the outer shell respectively have a first opening and a second opening in communication, and a connecting column is fixed on the inner side wall of the outer shell;

[0013] a digital angle ruler, one end of which extends into the outer shell through the first opening and is fixed to the connecting post; an angle ruler frame is fixedly connected to the movable scale of the digital angle ruler, and an angle digital display assembly is provided on the front side of the angle ruler frame;

[0014] a digital length ruler, one end of the ruler extending into the outer shell through the second opening and fixed to the connecting post; a length ruler frame slidably connected to the ruler body of the digital length ruler, and a length digital display assembly provided on the front side of the length ruler frame;

[0015] A digital height ruler, one end of the ruler body of the digital height ruler is arranged on the rear side of the length ruler frame, the height ruler frame is slidably connected to the ruler body of the digital height ruler, and a height digital display component is provided on the front side of the height ruler frame.

[0016] It can be seen from the above technical solution that compared with the existing technology, the utility model discloses a tobacco plant leaf measuring tool, which can measure the inclination angle of tobacco leaves through a digital angle ruler, measure the length of tobacco leaves through a digital length ruler, and measure the height of tobacco leaves through a digital height ruler. That is, the tool integrates angle, length, and height measurement into one, and there is no need to replace the measuring tool. It is not only easy to operate, but also can display the measurement results more intuitively. Compared with expensive image analysis and processing measurement devices, it has low cost, compact structure, and is easy to carry. It is more suitable for field measurement or laboratory measurement environment, and can be promoted to grassroots tobacco farms on a large scale.

[0017] Furthermore, a first pointer for indicating the scale on the body of the digital length ruler is provided on one side of the length ruler frame.

[0018] The beneficial effect of adopting the above technical solution is that when the tip of the first pointer is aligned with the tip of the tobacco leaf, it indicates that the length scale frame has moved into place.

[0019] Furthermore, a second pointer for indicating the scale on the body of the digital height gauge is provided on one side of the height gauge frame, and the needle tip of the second pointer is arranged flush with the needle tip of the first pointer.

[0020] The beneficial effect of adopting the above technical solution is that when the tip of the second pointer points to the tip of the tobacco leaf, it indicates that the height scale frame has moved into place.

[0021] Furthermore, a total display component for simultaneously displaying the measured angle, length, and height is provided on the front surface of the outer shell, and the total display component is electrically connected to the angle digital display component, the length digital display component, and the height digital display component.

[0022] The beneficial effect of adopting the above technical solution is that the angle, length and height measurement parameters can be displayed simultaneously on the total display component without having to observe the angle display component, length display component and height display component separately.

[0023] Furthermore, a first through hole is provided on the rear side surface of the outer shell, a second through hole is provided inside the connecting column, and a first locking screw passes through the first through hole and the second through hole to be connected to the fixed length thread of the digital display angle ruler.

[0024] The beneficial effects of the above technical solution are as follows: when the first locking screw is loosened, the fixed scale of the digital angle ruler can be rotated relative to the connecting column. The purpose of this design is that when not measuring, the movable scale and the fixed scale of the digital angle ruler are rotated to a horizontal position, thereby reducing the height of the measuring tool and facilitating portability; when it is necessary to measure the angle, the fixed scale is rotated from a horizontal state to a vertical state, and the first locking screw is tightened to securely connect the fixed scale to the connecting column, thereby ensuring that the fixed scale is always in a vertical state, making it easier for the fixed scale to coincide with the stem of the tobacco plant, and then the movable scale is rotated until it is close to the petiole to be measured and then stopped, at which point the angle display assembly displays the measured value of the tobacco leaf inclination angle.

[0025] Furthermore, a positioning rod is fixed on the first opening, and the fixed-size ruler body of the digital angle ruler can be vertically stopped at one side of the positioning rod.

[0026] The beneficial effect of the above technical solution is that when the ruler is rotated from a horizontal position to a vertical position, it stops on one side of the positioning rod and will not deviate further, indicating that the ruler is in the vertical position. This avoids the problem of the ruler not being in the vertical position and not being able to overlap with the tobacco plant stem, resulting in low measurement accuracy. In other words, the positioning rod realizes the automatic vertical positioning of the angle digital display ruler, eliminating the need for manual visual inspection to ensure that the ruler is in the vertical position, thus ensuring measurement accuracy.

[0027] Furthermore, one end of the ruler body of the digital height ruler is rotatably connected to the rear side surface of the length ruler frame.

[0028] The beneficial effect of adopting the above technical solution is that when measurement is not needed, the height digital ruler is rotated from a vertical state to a horizontal state, and the angle digital ruler is also rotated to a horizontal state. That is, at this time, the height digital ruler, the angle digital ruler and the length digital ruler are in a folded state. In this state, the measuring tool is small in size and easy to carry.

[0029] Furthermore, a mounting post is fixed on the rear side of the length ruler frame, and a sleeve hole is opened on the body of the digital height ruler near one end thereof, and the sleeve hole is rotatably sleeved on the mounting post.

[0030] The beneficial effect of adopting the above technical solution is that the digital height gauge can be easily rotated by the mounting column to realize the folding and unfolding of the digital height gauge.

[0031] Furthermore, a stop flange is provided on the outer peripheral wall of the mounting column, a second locking screw is screwed on the end of the mounting column away from the length scale frame, and the body of the digital height scale is clamped and fixed between the stop flange and the second locking screw.

[0032] The beneficial effect of adopting the above technical solution is: when the height digital ruler needs to be folded and folded down, the second locking screw is loosened. At this time, the height digital ruler can be rotated around the mounting column so that it is folded to a horizontal state. When measurement is required, the height digital ruler is rotated from the horizontal state to the vertical state, and then locked and fixed with the second locking screw to ensure that the height digital ruler is always in a vertical state during measurement, thereby ensuring the accuracy of tobacco leaf height measurement.

[0033] Furthermore, a positioning column is fixed on the rear side of the length ruler frame, and the ruler body of the digital height ruler can be vertically stopped at one side of the positioning column.

[0034] The beneficial effect of adopting the above technical solution is that when the height digital ruler is rotated from a horizontal state to a vertical state, the height digital ruler stops at one side of the positioning column, indicating that the height digital ruler is in a vertical state. That is, the height digital ruler is automatically positioned vertically by the positioning column, and there is no need for manual observation to see whether the height digital ruler is in a vertical state, thereby ensuring measurement accuracy.

[0058] The operating principle of this utility model is as follows:

[0059] In the initial state, the digital angle scale, digital length scale and digital height scale of the measuring tool are folded. Figure 6 The measuring tool in this state is small in size and easy to carry, making it very suitable for measuring tobacco leaves in tobacco fields and laboratories.

[0060] Before measurement, loosen the first locking screw 7 and rotate the fixed length 34 of the angle digital ruler 3 from the horizontal state to the vertical state. At this time, the fixed length 34 abuts against the positioning rod 11, and tighten the first locking screw 7 to fasten the fixed length 34 to the connecting column 2, thereby ensuring that the fixed length 34 is always in the vertical state; loosen the second locking screw 9 and rotate the height digital ruler 5 from the horizontal state to the vertical state. At this time, the height digital ruler 5 abuts against the positioning column 10, and then tighten the second locking screw 10 to fasten the height digital ruler 5 to the mounting column 8, thereby ensuring that the height digital ruler 5 is always in the vertical state.

[0061] When measuring the leaf inclination angle α of tobacco leaves, the fixed ruler 34 in a vertical state coincides with the stem of the tobacco plant, and then the movable ruler 31 of the angle digital display ruler 3 is rotated until it is close to the petiole to be measured and then the movable ruler 31 is stopped. At this time, the angle display component 32 displays the measured value of the tobacco leaf inclination angle.

[0062] When measuring the tobacco leaf length H1, use the length digital ruler 4, place the end of the petiole corresponding to the zero scale on the length digital ruler 4, and then move the length scale frame 41 on the length digital ruler 4 so that the tip of the first pointer 411 on the length scale frame 41 is vertically aligned with the tip of the tobacco leaf. At this time, the length digital display component 42 displays the measured value of the tobacco leaf length.

[0063] When measuring the tobacco leaf stiffness H2, the height scale frame 51 on the height digital display scale 5 is moved so that the tip of the second pointer 511 on the height scale frame 51 is horizontally aligned with the tip of the tobacco leaf. At this time, the height digital display component 52 displays the tobacco leaf height measurement value.

[0064] After the measurement is completed, the first locking screw 7 and the second locking screw 9 are loosened again, so that the angle digital display ruler 3 and the height digital display ruler 5 can be folded up again.

[0065] Of course, the measured α, H1, and H2 can be displayed and saved simultaneously in the main display assembly 6, which is convenient for later inspection and avoids the measured values ​​being changed due to the wrong movement of the movable ruler 31, the length ruler frame 41, and the height ruler frame 51.
