Description

Technical Field

[0001] This utility model relates to the field of agricultural information collection and measurement technology, and in particular to a cotton leaf angle measuring instrument. Background Technology

[0002] In cotton planting and breeding research, the angle between the leaf and the main stem is one of the important parameters reflecting the cotton plant structure, light utilization efficiency, and ventilation and light transmission performance. Accurate measurement of the leaf angle not only helps to optimize planting density and cultivation patterns, but also provides a scientific basis for cotton variety selection.

[0003] Most existing mechanical contact cotton leaf angle measuring devices obtain angle data by having two measuring arms attached to the main stem and the leaf respectively. They usually rely on manual hand operation, which cannot effectively hold the main stem. They are prone to large measurement errors due to hand shaking, plant shaking, or deviation of the measuring arm reference position during the measurement process. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cotton leaf angle measuring instrument, which aims to improve the problem that traditional measuring devices rely on manual hand-held alignment with the main stem, which is prone to shaking and affects the accuracy of measurement.

A limiting groove is opened inside the fixed plate, and the outer wall of the limiting plate is slidably connected to the inner wall of the limiting groove. A clamping plate is fixedly connected to the outer wall of the sliding plate, and a silicone pad is fixedly connected to the outer wall of the clamping plate. A support assembly is provided on the outer wall of the fixed plate.

[0007] Preferably, the support assembly includes a support column, the outer wall of which is fixedly connected to the outer wall of the fixing plate, and a measuring disk is fixedly connected to the outer wall of the support column.

[0008] Preferably, the outer wall of the measuring disc is fixedly connected with scale lines, the outer wall of the support column is rotatably connected with a support plate, and the inner wall of the support plate is fixedly connected with a pointer.

[0010] Preferably, a support ring is fixedly connected to the outer wall of the sliding column, and the outer wall of the support ring is slidably connected to the inner wall of the support plate.

[0011] Preferably, a second spring is fixedly connected to the outer wall of the support ring, and the outer wall of the second spring is fixedly connected to the inner wall of the support plate.

[0012] Preferably, a retaining post is fixedly connected to the outer wall of the sliding column.

[0013] Preferably, the outer wall of the locking pin is disposed on the outer wall of the measuring disc.

[0014] This utility model has the following beneficial effects:

[0015] 1.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a cotton leaf angle measuring instrument, including a fixed plate 1, a groove 2 inside the fixed plate 1, a spring 3 fixedly connected to the inner wall of the fixed plate 1, the outer wall of the spring 3 fixedly connected to the inner wall of the groove 2, a sliding plate 4 fixedly connected to the outer wall of the spring 3, the outer wall of the sliding plate 4 slidably connected to the inner wall of the groove 2, limit plates 5 fixedly connected to both outer walls of the sliding plate 4, a limit groove 6 inside the fixed plate 1, the outer wall of the limit plate 5 slidably connected to the inner wall of the limit groove 6, a clamping plate 7 fixedly connected to the outer wall of the sliding plate 4, a silicone pad 8 fixedly connected to the outer wall of the clamping plate 7, and a support assembly provided on the outer wall of the fixed plate 1.

[0025] Specifically, the fixing plate 1 and the groove 2 can provide fixed support for the spring 3 and also provide sliding support for the sliding plate 4. The elastic force of the springs 3 on both sides can push the sliding plates 4 on both sides to slide in the center. The sliding of the sliding plate 4 will cause the limiting plate 5 to slide on the inner wall of the limiting groove 6. The limiting groove 6 can provide sliding support for the limiting plate 5, and the limiting plate 5 can provide sliding support and limit for the sliding plate 4, ensuring the stability of the sliding plate 4. At the same time, the sliding of the sliding plate 4 will also cause the clamping plate 7 and the silicone pad 8 to slide synchronously. Through the centering and sliding of the clamping plates 7 and the silicone pad 8 on both sides, the cotton stem in the middle can be clamped to prevent shaking or slippage during the measurement process, thereby ensuring that the reference point for the angle measurement is fixed and the measurement is accurate. The clamping plate 7 driven by the spring 3 has a certain elasticity and can adapt to different stem diameters, improving compatibility. Meanwhile, the silicone pad 8 can provide soft protection for the cotton stem.

[0026] Reference Figure 3 The support assembly includes a support column 9, the outer wall of which is fixedly connected to the outer wall of the fixing plate 1, and a measuring disk 10 is fixedly connected to the outer wall of the support column 9; a scale line 11 is fixedly connected to the outer wall of the measuring disk 10, and a support plate 12 is rotatably connected to the outer wall of the support column 9; a pointer 13 is fixedly connected to the inner wall of the support plate 12.

[0027] Specifically, the fixing plate 1 can provide fixed support for the support column 9, which in turn provides fixed support for the measuring disk 10. The angle of the measuring disk 10 at various positions can be determined through the scale line 11. At the same time, the support column 9 can also provide rotational support for the support plate 12, ensuring the stability of the support plate 12's rotation. The support plate 12 can also provide fixed support for the pointer 13, and the support plate 12 can be aligned with the blade, maintaining the same position as the blade. By observing the position of the pointer 13 pointing to the scale line 11, the current angle of the support plate 12 can be determined, thereby measuring the included angle of the blade.

[0028] Reference Figure 4 A sliding column 14 is slidably connected to the inner wall of the support plate 12, and a handle 15 is fixedly connected to the outer wall of the sliding column 14; a support ring 16 is fixedly connected to the outer wall of the sliding column 14, and the outer wall of the support ring 16 is slidably connected to the inner wall of the support plate 12; a second spring 17 is fixedly connected to the outer wall of the support ring 16, and the outer wall of the second spring 17 is fixedly connected to the inner wall of the support plate 12; a locking column 18 is fixedly connected to the outer wall of the sliding column 14; the outer wall of the locking column 18 is set on the outer wall of the measuring plate 10.

[0029] Specifically, the support plate 12 provides sliding support for the sliding column 14, while the sliding column 14 provides fixed support for the handle 15. When the handle 15 is pushed, the sliding column 14 slides to the right, and the sliding of the sliding column 14 also causes the support ring 16 to slide, thereby causing the locking column 18 to slide to the back of the measuring disk 10. Then, the handle 15 is rotated to lock the locking column 18 into the measuring disk 10. When the handle 15 is released, the elastic force of the spring 17 pushes the support ring 16 to slide to the left, which in turn causes the sliding column 14 and the locking column 18 to slide to the left, allowing the locking column 18 to continue sliding towards the measuring disk 10. Applying pressure, through friction and clamping force, fixes the support plate 12 in the current position of the measuring disk 10. When it is necessary to release the limit of the support plate 12, push the handle 15 to drive the sliding column 14 and the locking column 18 to slide, so that the locking column 18 releases its clamping on the measuring disk 10. Then rotate the locking column 18 to make the locking column 18 in a horizontal position, releasing the contact with the measuring disk 10, and thus quickly releasing the limit of the support plate 12. By locking the support plate 12 in a certain corner of the measuring disk 10, angle deviation can be avoided during the reading or recording of data after the angle measurement is completed, thus improving the accuracy and repeatability of the measurement results.

[0030] Working principle: When the measuring instrument is needed, first place the cotton stem in the middle of the two silicone pads 8. Then, the spring force of the two springs 3 drives the sliding plates 4 and the limiting plates 5 on both sides to slide in the center. Then, the sliding of the sliding plates 4 drives the clamping plates 7 and the silicone pads 8 to slide in the center, so that the silicone pads 8 clamp and fix the cotton stem in the middle, preventing shaking or slippage during the measurement process, thereby ensuring that the reference point for the angle measurement is fixed and the measurement is accurate.

[0031] Then rotate the support plate 12 to align it with the cotton leaf, and push the handle 15 to slide. The sliding of the handle 15 will cause the sliding column 14 and the support ring 16 to slide. The sliding of the sliding column 14 will also cause the locking column 18 to slide behind the measuring disk 10. Then rotate the handle 15 again, which will cause the locking column 18 to rotate, so that the locking column 18 locks the back of the measuring disk 10. Then, the elastic force of the spring 17 will push the support ring 16 and the sliding column 14 to slide to the left, thereby causing the locking column 18 to clamp the measuring disk 10, so that the support plate 12 is fixed at the current angular position of the measuring disk 10. During the reading or recording of data, the angle deviation is avoided, and the accuracy and repeatability of the measurement results are improved.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
