Description

Technical Field

[0001] The utility model relates to the technical field of crop plant height measurement, in particular to a device for measuring the plant height of crops. Background Art

[0002] Crop plant height measurement is the measurement of the distance from the root neck to the top of the crop. It is an important means to understand plant growth and health status as well as breeding and genetic research.

[0003] Currently, the height of crops is mainly measured using a measuring device. For example, in a crop height measuring device with patent number CN220689974U, a support rod is fixed by a positioning block, and then the crops are fixed along the support rod, and the height of the crops is measured using a tape measure. However, this results in the existing technology requiring the support rod to fit the crops. Since some crops, such as corn, have aerial roots, and the aerial roots extend away from the crops, the positioning block cannot be directly fixed on the ground next to the crops. When fixing the crops for measurement, the crops need to be tilted along the support rod, making the measurement results inaccurate. In addition, the positioning block is directly fixed to the support rod, and the fields next to the crops are not flat due to irrigation and erosion. Therefore, the positioning block cannot ensure that the support rod can be arranged in a vertical upward direction. When the support rod is tilted, the error in measuring the height of the crops will be further increased. Therefore, there are certain usage defects in the existing technology. This patent aims to provide a crop height measuring device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0032] Reference Figures 1-6 The utility model provides a device for measuring the height of crops, comprising:

[0033] The fixing plate 1 is fixed to one side of the crop. The end of the fixing plate 1 close to the crop is fixedly connected to the mounting plate 2. The mounting plate 2 is distributed in the horizontal direction, and the top surface is flush with the root neck of the crop.

[0034] The positioning rod 3 is provided on the mounting plate 2. The mounting plate 2 is provided with an adjusting member. The adjusting end of the adjusting member is connected to the positioning rod 3 so that the positioning rod 3 is lifted and lowered in the vertical direction and contacts the ground.

[0035] The measuring rod 4 is detachably connected to the top surface of the mounting plate 2 , the starting measuring end of the measuring rod 4 is flush with the top surface of the mounting plate 2 , and the ending measuring end of the measuring rod 4 extends vertically upward.

[0036] The utility model fixes a fixing plate 1 on the field on one side of the crop, and extends the fixing plate 1 along the direction of the crop to fix the mounting plate 2, so that the mounting plate 2 is close to the crop, and the mounting plate 2 is distributed in the horizontal direction, and the top surface of the mounting plate 2 corresponds to the root neck position of the crop. By arranging a measuring rod 4 on the mounting plate 2, the starting measuring end of the measuring rod 4 directly corresponds to the root neck of the crop, and combined with the ending measuring end, it extends vertically upward, which can accurately measure the plant height close to the crop. In addition, by arranging a positioning rod 3 on the mounting plate 2, the positioning rod 3 is raised and lowered by an adjusting piece, and the positioning rod 3 is contacted with the ground to adjust the height of the mounting plate 2, so as to ensure that the mounting plate 2 is distributed horizontally and can be flush with the root neck of the crop, thereby improving the accuracy of measuring the plant height of the crop.

[0037] It should be noted that the top surface of the mounting plate 2 in the present technical solution corresponds to the root neck position, which is the connection end between the top of the aerial root and the stem.

[0038] In this technical solution, when it is inconvenient to measure crops directly with structures such as aerial roots, the positioning rod 3 is used to extend into the gap between the aerial roots to support the mounting plate 2, and the fixing plate 1 is fixed to the ground in the direction away from the crops to achieve stable fixation of the mounting plate 2. The positioning rod 3 is raised and lowered to contact the ground, and the height of the mounting plate 2 and the angle between the mounting plate 2 and the ground are adjusted to meet the positioning and fixation requirements of the mounting plate 2.

[0039] In one embodiment of the present technical solution, the diameter of the positioning rod 3 is smaller than the gap between the aerial roots, and a gasket 5 is fixed to the bottom end of the positioning rod 3 to increase the contact area with the ground.

[0040] Furthermore, it also includes:

[0041] A level 6 is fixed to the top surface of the fixed plate 1;

[0042] The fork 7 is fixedly connected to the bottom surface of the fixing plate 1 on a side away from the crops. The fork 7 extends vertically downward and is used for fixing to the ground.

[0043] The fixed plate 1 is fixed by inserting the fork 7 into the ground, and the level ruler 6 fixed to the top surface of the fixed plate 1 can assist the surveying staff in making horizontal adjustments. After the fork 7 is inserted into the ground, the staff observes the spirit level and raises and lowers the positioning rod 3 to make the spirit level be located between the horizontal lines.

[0044] Furthermore, the adjusting member includes:

[0045] The knob 8 is connected to the bottom surface of the mounting plate 2 through a bearing. A through hole is provided in the center of the knob 8. A sleeve 9 is fixed in the through hole. The inner ring of the sleeve 9 is provided with a thread. The positioning rod 3 is threadedly connected to the sleeve 9.

[0046] The limiting portion is provided on the positioning rod 3 and is connected to the measuring rod 4 in a limiting manner so that the positioning rod 3 is axially fixed relative to the measuring rod 4 .

[0047] The limiting part prevents the positioning rod 3 from rotating relative to the sleeve 9, so when the knob 8 is turned, the sleeve 9 rotates to adjust the lifting and lowering of the positioning rod 3, making it convenient to lift the positioning rod 3 and adjust the angle of the mounting plate 2 so that the measuring rod 4 can measure in the horizontal direction.

[0048] Furthermore, a clamping block 10 is fixedly connected to the top surface of the mounting plate 2 . The clamping block 10 is a square structure. A clamping slot is provided at the bottom end of the measuring rod 4 . The clamping block 10 is plugged into the clamping slot.

[0049] By plugging the measuring rod 4 into the clamping block 10 , the measuring rod 4 and the mounting plate 2 can be easily disassembled and used.

[0050] Furthermore, the limiting portion includes a pair of limiting plates 11, which are cross-distributed. The top end of the positioning rod 3 passes through the block 10 and is fixed to the center of the pair of limiting plates 11. The pair of limiting plates 11 are slidingly connected in the card slot.

[0051] By utilizing the square structure of the card slot, a pair of limit plates 11 are cross-distributed and limitedly slid in the card slot, so that the limit plates 11 are distributed along the diagonal direction of the card slot to limit the positioning rod 3 and prevent the positioning rod 3 from rotating relative to the measuring rod 4.

[0052] Furthermore, the measuring rod 4 includes a first square tube 41, which is plugged into the clamping block 10. A guide seat 46 is fixedly connected to the inner top of the first square tube 41. A guide hole is opened in the center of the guide seat 46. A first circular tube 42 is slidably connected in the guide hole. A support plate 45 is fixedly connected to the bottom end of the first circular tube 42. The support plate 45 is limitedly slidably connected in the first square tube 41.

[0053] The sliding fit between the first square tube 41 and the first round tube 42 satisfies the telescopic structure of the measuring rod 4 . When the height of the crop is greater than the first square tube 41 , the first round tube 42 is extended to measure the crop.

[0054] Furthermore, scale lines are provided on the side of the first square tube 41 and the first circular tube 42 close to the crops. The bottom end of the first square tube 41 is the measurement starting end, and the top end of the first circular tube 42 is the measurement ending end.

[0055] Specifically, the scale line at the bottom end of the first square tube 41 is zero, and the scale line at the top end of the first circular tube 42 is zero. When the height of the crop plant does not exceed that on the first square tube 41, the position of the top end of the crop corresponding to the position on the first square tube 41 in the horizontal direction is the plant height of the crop. When the height of the crop plant exceeds the first square tube 41, the first circular tube 42 is stretched and the top end is horizontally aligned with the top end of the crop. At this time, the sum of the length of the first circular tube 42 extending out of the first square tube 41 plus the length of the first square tube 41 is the plant height of the crop.

[0056] In one embodiment of the present technical solution, a hanging ring 44 is fixedly connected to the side wall of the first square tube 41. When the crops fall over or the structure bends, a binding rope (not shown in the figure) is passed through the hanging ring 44 to tie the crops to the first square tube 41, so that the crops remain extended in the vertical direction.

[0057] Furthermore, a top plate 43 is hingedly connected to the top of the first circular tube 42 .

[0058] By rotating the top plate 43 , the top plate 43 is extended toward the crops in a horizontal direction so that the bottom surface of the top plate 43 contacts the top of the crops, thereby improving the accuracy of measuring the height of the crops.

[0059] The working principle of the crop height measuring device of the utility model:

[0060] Taking the measurement of corn plant height as an example, select the crop to be measured, insert the fork 7 into the ground on one side of the crop, point the fixing plate 1 towards the direction of the crop, insert the measuring rod 4 into the block 10, and at the same time, a pair of limit plates 11 are also limited and slid into the slot, and then extend the positioning rod 3 into the gap between the aerial roots. By turning the knob 8, the positioning rod 3 is extended vertically downward, and the positioning rod 3 contacts the ground, and the level bubble of the spirit level 6 is observed. The mounting plate 2 is arranged in the horizontal direction, and the top surface of the mounting plate 2 corresponds to the root neck of the crop. The positioning rod 3 and the fork 7 are used to stably fix the mounting plate 2 and the fixing plate 1 from both ends.

[0061] Then, observe the positional relationship between the top of the crop and the measuring rod 4. When the crop exceeds the first square tube 41, pull out the first circular tube 42, then rotate the top plate 43 so that the bottom surface of the top plate 43 contacts the top of the crop, observe the extended length of the first circular tube 42, and add it to the length of the first square tube 41 to obtain the plant height of the crop.

[0062] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0063] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
