Description

Technical Field

[0001] The invention 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 flue-cured 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 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 traits of flue-cured tobacco, it is necessary to carry multiple 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 the length, angle and height measuring tools, digital rulers have been widely used by surveyors because of their ability to display measurement values ​​in real time and their convenience in use, such as digital calipers, digital height gauges, digital angle rulers, etc.

[0004] Among them, the digital caliper (such as CN208688352U-digital caliper) is a measuring tool for measuring length, inner and outer diameters, and depth. The digital caliper is mainly composed of a ruler body, a ruler frame, and a digital display component. The ruler frame is slidably connected to the ruler body, and the digital display component is set on the ruler frame. By moving the ruler frame, the measured value is displayed in real time on the digital display component.

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

[0006] The digital display angle ruler (such as CN218002424U-digital display 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 plant leaves and the angle of tobacco plant 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. 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. Summary of the invention

[0009] In view of this, the present invention provides a tobacco plant 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, and is more suitable for large-scale promotion to grassroots tobacco farms.

[0010] In order to achieve the above object, the present invention adopts the following technical solution:

[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 that are connected, 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 column, an angle ruler frame is fixedly connected to the movable ruler of the digital angle ruler, and an angle digital display component is provided on the front side of the angle ruler frame;

[0014] A digital length ruler, one end of which extends into the outer shell through the second opening and is fixed to the connecting column, a length ruler frame is slidably connected to the body of the digital length ruler, and a length digital display component is provided on the front side of the length ruler frame;

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

[0016] It can be seen from the above technical scheme that compared with the prior art, the present invention discloses a tobacco 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 widely promoted to grassroots tobacco farms.

[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 it is convenient to display the angle, length and height measurement parameters on the total display component at the same time, without having to observe the angle display component, the length display component and the 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 angle ruler.

[0024] The beneficial effects of the above technical solution are as follows: the first locking screw is loosened, at which time the fixed length 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 length and the fixed length of the digital angle ruler are rotated to a horizontal position to reduce the height of the measuring tool and facilitate carrying; when the angle needs to be measured, the fixed length is rotated from a horizontal state to a vertical state, and the first locking screw is tightened to fasten the fixed length to the connecting column, thereby ensuring that the fixed length is always in a vertical state, so that the fixed length and the stem of the tobacco plant are easily overlapped, and then the movable length is rotated until it is close to the petiole to be measured and then the movable length is stopped, and at this time the angle display component displays the measured value of the tobacco leaf inclination.

[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 on one side of the positioning rod.

[0026] The beneficial effect of adopting the above technical solution is that when the fixed ruler rotates from the horizontal state to the vertical state, the fixed ruler stops at one side of the positioning rod and will not deviate any more, indicating that the fixed ruler is in the vertical state, thus avoiding the problem that the fixed ruler is not in the vertical state and cannot overlap with the stem of the tobacco plant, resulting in low measurement accuracy. That is, the automatic vertical positioning of the fixed ruler of the angle digital display ruler is realized through the positioning rod, and there is no need to manually observe whether the fixed ruler is in the vertical state by eye, thereby 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 display ruler is rotated from a vertical state to a horizontal state, and the angle digital display ruler is also rotated to a horizontal state. That is, at this time, the height digital display ruler, the angle digital display ruler and the length digital display ruler are in a folded state. The measuring tool in this state is small in size and easy to carry.

[0029] Furthermore, a mounting post is fixed on the rear side of the length scale frame, and a sleeve hole is provided on the body of the digital height scale 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 with 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 an 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 display ruler needs to be folded and laid down, the second locking screw is loosened. At this time, the height digital display ruler can be rotated around the mounting column so that it can be folded to a horizontal state. When measurement is required, the height digital display ruler is rotated from a horizontal state to a vertical state, and then the second locking screw is used to lock and fix it, ensuring that the height digital display 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 on one side of the positioning column.

[0034] The beneficial effect of adopting the above technical solution is that when the height digital ruler rotates 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 to manually observe whether the height digital ruler is in a vertical state with the eyes, thereby ensuring measurement accuracy.

Figure 6 The measuring tool in this state is small in size and easy to carry, which is 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 a horizontal state to a 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 and the connecting column 2, thereby ensuring that the fixed length 34 is always in a vertical state; loosen the second locking screw 9 and rotate the height digital ruler 5 from a horizontal state to a 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 and the mounting column 8, thereby ensuring that the height digital ruler 5 is always in a vertical state.

[0061] When measuring the leaf inclination angle α of tobacco leaves, the vertical fixed ruler 34 is overlapped with the stem of the tobacco plant, and then the movable ruler 31 of the angle digital display ruler 3 is rotated to approach the petiole to be measured and then the movable ruler 31 is stopped.

[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 measured value of the tobacco leaf height.

[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, 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.
