Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco planting, and particularly relates to a device for measuring agronomic trait data of tobacco plants. Background Art

[0002] Since the leaves of tobacco plants are alternate, the plant type and leaf state of tobacco plants are directly related to the leaf extension degree and extension direction, and ultimately affect the utilization rate of leaf surface to light and the accumulation of dry matter of the plants themselves. Therefore, those skilled in the art have gradually paid attention to and studied the relationship between agronomic traits such as the plant type of tobacco plants and the quality of tobacco leaves. However, due to the long growth period of tobacco and the large differences in the body shape changes at each stage, a large amount of data needs to be measured. The measurement of agronomic trait data of the plant type state in the prior art includes measuring the leaf height, leaf layer width, top width, and bottom width of tobacco plants in the natural state, and the measurement positions are as shown in the appendix Figure 1 ; the measurement of agronomic trait data of the leaf state includes investigating and measuring the leaf length and width, stem-leaf angle, natural state lateral distribution width, and leaf extension state of the 6th / 10th / 14th / 18th leaf positions (excluding 2 basal leaves, if not available, no investigation is required, and leaves above the 18th position are reasonably added according to the number of leaves in each subsequent treatment, and the last 1 / 3 are the key investigation leaf positions) at 40d and 60d after transplanting, at topping, and every 15d - 20d after topping. The measurement positions are as shown in the appendix Figure 2 . Therefore, the staff needs to carry a variety of tools each time, and after the tobacco plants enter the vigorous growth period (at this time, the tobacco plants are relatively large in volume), two people are required to cooperate for the measurement, and the overall operation is rather cumbersome. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a device for measuring agronomic trait data of tobacco plants. The structure of the utility model is simple, easy to carry, and can adapt to the measurement of agronomic trait data of tobacco plants throughout the growth period. At the same time, the data can be read by one person, and the practicability is relatively strong.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A device for measuring agronomic trait data of tobacco plants includes a threaded rod and a square adjustment block screwed with the threaded rod through a preset threaded hole. The center line of the adjustment block overlaps with the axis of the threaded rod, and one vertical side of the adjustment block is rotatably connected to a table box with a hollow rectangular structure. An axle rod perpendicular to the threaded rod is rotatably arranged on the inner wall of the table box, and a gear is coaxially fixed on the axle rod. Two wire rods parallel to each other and symmetrically arranged with respect to the axis of the gear are meshed and driven with the gear, and the wire rods are slidably matched with through holes preset on the table box;

[0006] Scale lines for marking lengths are provided on the sides of the wire rods and the table box away from the threaded rod.

[0007] Preferably, the side of the watch box facing away from the scale line is connected to the adjusting block through a disc damping rotating shaft.

[0008] Preferably, a handwheel is also coaxially provided on the shaft rod, and the top of the handwheel penetrates through a long hole preset on the top surface of the watch box and is exposed to the outside.

[0009] Preferably, rectangular notches are formed on the top surfaces of the opposite ends of the two wire rods. A swing rod and the wire rods that are in clearance fit with the rectangular notches are both provided with screw holes, and a hand-tightened bolt is screwed into the screw holes on the swing rod and the wire rods in sequence.

[0010] Preferably, the device further includes a conical column foot with the sharp part facing downwards, and the top end of the conical column foot is assembled with the bottom end of the threaded rod through a bearing.

[0011] Preferably, semi-circular angle gauges are respectively fixed at the horizontal two ends of the outer side of the adjusting block facing away from the watch box.

[0012] Preferably, an infrared emitter is also vertically provided on the outer side of the adjusting block facing away from the wire rod, and a bubble level is provided at the bottom end of the side of the watch box with a scale line.

[0013] The working process of the present utility model is as follows:

[0014] Move the present utility model to the tobacco plant at the target position. First, ensure that the top surfaces of the square adjusting block and the watch box are flush. Then, use the conical column foot to pierce into the soil, and at the same time, adjust the threaded rod to be perpendicular to the horizontal plane through the bubble level.

[0015] When measuring the two vertical agronomic trait length data of "leaf layer height" and "position of leaf layer width on the leaf layer height", rotate the watch box 90° relative to the adjusting block and still keep the top surfaces of the two aligned, so that the two wire rods are arranged one above the other. At the same time, rotate the threaded rod relative to the conical column foot, so that the adjusting block drives the watch box and the wire rods to move vertically to the measurement position of the tobacco plant within the measurement range of the two wire rods. Then, adjust the watch box to face the tobacco plant, and by reading the position of the scale line, the corresponding agronomic trait data can be obtained.

[0016] When measuring the horizontal agronomic trait length data such as "leaf layer width", "top width", "bottom width", "upper second shed horizontal extension", "length from leaf tip to the horizontal line where the leaf base is located (positive)", "natural horizontal length of the leaf", "length from leaf tip to the horizontal line where the leaf base is located (negative)", "mid - part horizontal extension", etc., reset the watch box, that is, keep the state where the bubble level is facing downwards. At this moment, the two wire rods are horizontal. Then, after the adjusting block drives the watch box and the wire rods to move to the target height, the corresponding agronomic trait data can be obtained by reading the position of the scale line. Since some of the above - mentioned agronomic traits involve data of "natural drooping state of the leaf", in order to improve the measurement accuracy, a hand - tightened bolt can be used to connect the swing rod to the rectangular notch of the wire rod, and the swing rod can be used to indicate by closely approaching the corresponding part of the tobacco plant without pressure, and then measure.

[0017] When measuring the agronomic trait of "leaf angle", a semi-circular angle ruler can be used to approximate the corresponding part of the tobacco plant for measurement.

[0018] The utility model can also drive the shaft rod and the gear to rotate synchronously by adjusting the hand wheel, and then drive the two wire rods to drive the swing rod to move in opposite or back-to-back directions. On the one hand, the measurement range of the wire rod can be adjusted, and on the other hand, the instant position of the swing rod relative to the tobacco plant can be adjusted. Furthermore, the two swing rods can locate the measurement points of some agronomic traits, such as "mid-section horizontal extension", etc., which is convenient for a single person to quickly read the corresponding data. Moreover, when the utility model is not in use, the end spacing of the two wire rods can be reduced and the parallel threaded rods can be maintained, which is convenient for storage.

[0019] Compared with the prior art, the utility model has the following advantages: the structure of the utility model is simple, it is convenient to carry and can adapt to the measurement of agronomic trait data during the whole growth period of the tobacco plant. At the same time, the data can be read by one person, and the practicability is relatively strong. Description of the Drawings

[0026] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further details the utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0027] Such as Figures 3 - 6As shown in the figure, a device for measuring the agronomic traits of tobacco plants includes a conical column foot 12, a threaded rod 1, and a square adjusting block 13 that is screwed to the threaded rod 12 through a preset threaded hole. The center line of the adjusting block 13 overlaps with the axis of the threaded rod 1, and one vertical side of the adjusting block 13 is rotatably connected to a table box 2 with a hollow rectangular structure through a disc damping rotating shaft 16. Horizontally at both ends of the outer side of the adjusting block 13 facing away from the table box 2, semi-circular angle rulers 14 are fixedly provided. The sharp part of the conical column foot 12 is arranged downward, and the top end of the conical column foot 12 is assembled with the bottom end of the threaded rod 1 through a bearing 11.

[0028] A shaft rod perpendicular to the threaded rod 1 is rotatably arranged on the inner wall of the table box 2. A gear 23 is coaxially fixed on the shaft rod. Two wire rods 24 that are parallel to each other and symmetrically arranged with respect to the axis of the gear 23 are in meshing transmission with the gear 23, and the wire rods 24 are slidably matched with preset through holes on the table box 2. A handwheel 22 is also coaxially arranged on the shaft rod. The top of the handwheel 22 penetrates through a long hole preset on the top surface of the table box 2 and is exposed to the outside. Rectangular notches 27 are opened on the top surfaces of the opposite ends of the two wire rods 24. The swing rod 25 and the wire rods 24 that are in clearance fit with the rectangular notches 27 are both provided with threaded holes, and a hand-tightening bolt 26 is sequentially screwed into the threaded holes on the swing rod 25 and the wire rods 24.

[0029] Scale lines for marking lengths are provided on the side surfaces of the wire rods 24 and the table box 2 away from the threaded rod 1. An infrared emitter 15 is also vertically provided on the outer side of the adjusting block 13 facing away from the wire rods 24. A bubble level 21 is provided at the bottom end of the side surface of the table box 2 with scale lines.

[0030] The working process of the present utility model is as follows:

[0031] Move the present utility model to the tobacco plant at the target position. First, ensure that the top surfaces of the adjusting block 13 and the table box 2 are flush. Then, use the conical column foot 12 to pierce into the soil, and at the same time, adjust the threaded rod 1 to be perpendicular to the horizontal plane through the bubble level 21.

[0032] When measuring the two vertical agronomic trait length data of "leaf layer height" and "position of leaf layer width on the leaf layer height" (see Figure 1 ), rotate the table box 2 relative to the adjusting block 13 by 90°, and still keep the top surfaces of the two aligned, so that the two wire rods 24 are arranged one above the other. At the same time, rotate the threaded rod 1 relative to the conical column foot 12, so that the adjusting block 13 drives the table box 2 and the wire rods 24 to move vertically until the tobacco plant measurement part is within the measurement range of the two wire rods. Then, adjust the table box 2 to face the tobacco plant, and by reading the positions of the scale lines, the data of the corresponding agronomic traits can be obtained.

[0033] When measuring horizontal agronomic trait length data such as "leaf layer width", "top width", "bottom width", "lateral extension of the second upper layer", "length from leaf tip to the horizontal line where the leaf base is located (positive)", "horizontal length of the leaf in natural state", "length from leaf tip to the horizontal line where the leaf base is located (negative)", and "mid - part lateral extension" (see Figure 1 and Figure 2 ), reset the table box 2 to keep the bubble level 21 facing down. At this moment, the two wire rods 24 are horizontal. Then, after driving the table box 2 and the wire rods 24 to move to the target height by the adjusting block 13, the data of the corresponding agronomic traits can be obtained by reading the position of the scale line. Since the above - mentioned agronomic traits involve some data of the "natural drooping state of the leaf", in order to improve the measurement accuracy, the swing rod 25 can be connected to the rectangular notch 27 of the wire rod 24 by hand - tightening the bolt 26, and the swing rod 25 can be used to indicate by closely approaching the corresponding part of the tobacco plant without pressure, and then measure.

[0034] When measuring the agronomic trait of "leaf angle", a semi - circular angle ruler 14 can be used to approach the corresponding part of the tobacco plant for measurement.

[0035] The utility model can also drive the shaft rod and the gear 23 to rotate synchronously by adjusting the hand wheel 22, so that the two wire rods 24 drive the swing rod 25 to move in opposite or back - to - back directions. On the one hand, the measurement range of the wire rod 24 can be adjusted, and on the other hand, the instant position of the swing rod 25 relative to the tobacco plant can be adjusted. Furthermore, the two swing rods 25 can locate the measurement points of some agronomic traits, such as "mid - part lateral extension", etc., which is convenient for a single person to quickly read the corresponding data. Moreover, when the utility model is not in use, the end - to - end distance of the two wire rods 24 can be reduced and the parallel threaded rod 1 can be maintained, which is convenient for storage.
