Description

Technical Field

[0001] This utility model relates to the field of agricultural auxiliary equipment technology, and in particular to a crop growth status detection component. Background Technology

[0002] Measuring the height of crop plants can be done by taking a picture of both a ruler and the crop, then determining the pixel length of the ruler in the image—specifically, identifying the markings on the ruler and converting them to actual lengths (e.g., centimeters or inches). By comparing the height of the crop in the image with the pixel length of the ruler, the actual height of the crop can be calculated. When taking the picture, ensure the ruler is held vertically and avoid tilting it.

[0003] However, during the shooting process, the ruler is judged to be vertical by human eyes before taking a picture. But human eyes may be affected by visual illusions. At the same time, environmental factors such as lighting conditions, shadows and reflections can also affect human eye judgment. The tilt of the ruler will lead to a large deviation between the calculated result and the actual result. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a crop growth status detection component, which aims to solve the technical problem that in the prior art, the human eye judges the ruler to be in the vertical direction before taking a picture, but the human eye may be affected by visual illusions, and environmental factors such as lighting conditions, shadows and reflections will also affect the human eye's judgment. The tilt of the ruler will lead to a large deviation between the calculated results and the actual situation.

[0005] This utility model provides a crop growth status detection component, including a main scale, a support plate, a sliding member, a leveling indicator, and a first camera. The leveling indicator is rotatably connected to the top of the main scale and is used to determine the tilt angle of the main scale. The sliding member is sleeved on the main scale and can slide along the length of the main scale. The sliding member is provided with a locking component and a hinge ear. The locking component is used to lock the sliding member to the main scale. The support plate is hinged to the hinge ear. The hinge ear is provided with a limiting member, which is used to block the support plate in the vertical or horizontal direction, so that the support plate is parallel to or perpendicular to the main scale. The first camera is detachably mounted on the support plate and is used to photograph the main scale and the crop.

[0006] Furthermore, the limiting member includes a first limiting block and a second limiting block, the first limiting block and the second limiting block being symmetrical about the hinge point of the bearing plate and the hinge ear, the first limiting block being used to abut against the upper surface of the bearing plate, the second limiting block being used to abut against the lower surface of the bearing plate, and the second limiting block being used to restrict the bearing plate to a horizontal position.

[0007] Furthermore, the locking assembly includes a puller, a spring, and a stop plate. The main scale has several teeth spaced apart along its length on its side. The sliding member has a through hole, allowing the puller to be inserted into its interior. The stop plate is located on the inner wall of the through hole. The puller has a through groove, and both the spring and the stop plate are located within the through groove. One end of the spring is connected to the inner wall of the through groove, and the other end is connected to the stop plate. The spring drives the puller to insert into the gap between two adjacent teeth to lock the sliding member onto the main scale. The puller disengages from the gap between two adjacent teeth and compresses the spring, allowing the sliding member to slide along the length of the main scale.

[0008] Furthermore, the sliding member is provided with a pulley, which abuts against the main scale to allow the sliding member to slide on the main scale.

[0009] Furthermore, the bottom of the main ruler is rotatably connected to a spike, which is used to insert into the ground to fix the main ruler. The main ruler and the spike rotate relative to each other on the horizontal plane to adjust the orientation of the main ruler.

[0010] Furthermore, it also includes a second camera, which is detachably connected to the main scale, and is used to photograph the fruit of crops.

[0011] Furthermore, the second camera includes a main unit, a light shield, and a background plate. One side of the light shield is connected to the main unit, and the other side is connected to the background plate. An opening is provided at the connection between the background plate and the light shield, allowing fruit to be placed inside the light shield. The ring light is used to illuminate the interior of the light shield, and the main unit is used to photograph the fruit placed inside the light shield.

[0012] Beneficial effects: This utility model provides a crop growth status detection component, including a main ruler, a support plate, a sliding member, a leveling indicator, and a first camera. The leveling indicator is used to determine the tilt angle of the main ruler and prevent it from tilting. After the sliding member slides along the length of the main ruler to the target position, a locking component is used to lock the sliding member onto the main ruler. The first camera is detachably mounted on the support plate and is used to photograph the main ruler and the crops in the target area. Since the leveling ensures that the main ruler is in the vertical direction, the support plate is kept in a horizontal position under the action of the limiting member when it is unfolded. The first camera can obtain more accurate calculation results by placing it on the support plate and taking pictures. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figures 1 to 5This utility model provides a crop growth status detection component, including a main ruler 1, a support plate 2, a sliding member 3, a leveling indicator 4, and a first camera 5. The leveling indicator 4 is rotatably connected to the top of the main ruler 1 and is used to determine the tilt angle of the main ruler 1. The sliding member 3 is sleeved on the main ruler 1 and can slide along the length direction of the main ruler 1. The sliding member 3 is provided with a locking component 6 and a hinge ear 7. The locking component 6 is used to lock the sliding member 3 onto the main ruler 1. The support plate 2 is hinged to the hinge ear 7. The hinge ear 7 is provided with a limiting member 8, which is used to block the support plate 2 in the vertical or horizontal direction, making the support plate 2 parallel to or perpendicular to the main ruler 1. The first camera 5 is detachably mounted on the support plate 2 and is used to photograph the main ruler 1 and crops within the target area. Crops include rice, wheat, sorghum, and other sorghum plants.

[0023] Specifically, the leveling indicator is a sealed glass tube containing liquid and an air bubble. The position of the air bubble indicates whether the main ruler is level. A center line is drawn on the outside of the leveling indicator, and the air bubble needs to be adjusted to the center line to ensure the main ruler is vertical. When the main ruler 1 is inserted into the ground, leveling is achieved by pushing the circumference of the main ruler 1 to adjust its tilt. Rotating the leveling indicator 4 ensures that the air bubble inside the leveling indicator 4 is within the center line of the leveling indicator 4, regardless of its orientation, to ensure the main ruler 1 remains vertical. Since the limiting member 8 is used to limit the support plate 2 to be perpendicular to the main ruler 1, the support plate 2 is in a horizontal position when the main ruler 1 is vertical. At this time, the first camera 5 can be placed on the support plate 2. Since different plants have different heights, the height needs to be adjusted by sliding the slider 3 on the main ruler 1 to obtain a better shooting angle. When the slider 3 slides to the appropriate position, it can be locked by the locking component 6 to ensure stability during the shooting process. Taking rice as an example, during the shooting process, it is necessary to ensure that the main ruler 1 and the rice are on the same plane and adjacent to each other so that their heights can be directly compared. The comparison method is as follows: compare the top of the rice in the image with the dimensions on the main ruler.

[0024] After filming is completed, since the first camera 5 is detachably mounted on the support plate 2, it can be disassembled, and the support plate 2 can be flipped to be parallel to the main scale 1 for easy storage. The first camera 5 and the support plate 2 can be detached by a plug-in connection. Specifically, a connecting post is provided on the support plate 2, and the bottom of the first camera 5 is provided with a plug-in hole that matches the connecting post. The connecting post is plugged into the connecting hole to complete the connection.

[0025] In one feasible implementation, the limiting member 8 includes a first limiting block 81 and a second limiting block 82, which are symmetrical about the hinge point of the support plate 2 and the hinge ear 7. The first limiting block 81 abuts against the upper surface of the support plate 2, and the second limiting block 82 abuts against the lower surface of the support plate 2, thus limiting the support plate 2 to a horizontal position. Specifically, the first limiting block 81 is located above the second limiting block 82, and is closer to the main scale 1 than the second limiting block 82. Therefore, when the support plate 2 is flipped to be perpendicular to the main scale 1, the support plate 2 simultaneously abuts against both the first limiting block 81 and the second limiting block 82, providing sufficient support for the support plate 2. When the support plate 2 is flipped to be parallel to the main scale 1, the support plate 2 also simultaneously abuts against both the first limiting block 81 and the second limiting block 82, effectively preventing the support plate 2 from over-flipping.

[0026] In one feasible embodiment, the locking assembly 6 includes a puller 61, a spring 62, and a stop plate 63. The main scale 1 has a plurality of locking teeth 11 spaced apart along its length on its side. The sliding member 3 has a through hole 31, allowing the puller 61 to be inserted into the interior of the sliding member 3. The stop plate 63 is disposed on the inner wall of the through hole 31. The puller 61 has a through groove 611. The spring 62 and the stop plate 63 are both located within the through groove 611. One end of the spring 62 is connected to the inner wall of the through groove 611, and the other end is connected to the stop plate 63. The spring 62 drives the puller 61 to insert into the gap between two adjacent locking teeth 11 to lock the sliding member 3 onto the main scale 1. The puller 61 disengages from the gap between two adjacent locking teeth 11 and compresses the spring 62, allowing the sliding member 3 to slide along the length of the main scale 1. Specifically, when the slider 3 needs to be moved, pulling out the pull plug 61 disengages it from the gap between the two locking teeth 11, allowing the slider 3 to slide. At this time, the spring 62 is compressed. When the slider 3 slides to the appropriate position, the pull plug 61 is released. Under the elastic force of the spring 62, the spring 62 drives the pull plug 61 to insert into the gap between two adjacent locking teeth 11 to lock the slider 3 onto the main scale 1.

[0027] In one feasible embodiment, the slider 3 is provided with a pulley 32, which abuts against the main scale 1 to allow the slider 3 to slide on the main scale 1. The pulley 32 improves the smoothness of the slider 3 during the sliding process.

[0028] In one feasible implementation, a spike 12 is rotatably connected to the bottom of the main ruler 1. The spike 12 is used to insert into the ground to fix the main ruler 1. The main ruler 1 and the spike 12 rotate relative to each other on a horizontal plane to adjust the orientation of the main ruler 1. Specifically, the main ruler 1 and the spike 12 are hinged to each other to achieve a rotatable connection. In this embodiment, the main ruler 1 can be rotated to photograph crops in various directions.

[0029] In one feasible implementation, a second camera 9 is also included. The second camera 9 is detachably connected to the main scale 1 and is used to photograph the fruit of crops. Taking rice as an example, the height of the rice plant is an important indicator of rice growth, related to the rice's growth status, nutritional status, and potential environmental stress. The size of the rice grains reflects the rice's development and potential pest and disease problems. Monitoring these two indicators helps to adjust field management measures in a timely manner, such as irrigation, fertilization, and pest and disease control. Therefore, information about the rice grains can be obtained through the second camera 9. The second camera 9 and the main scale 1 can be detachably connected by setting another support plate. Specifically, a connecting post is set on the support plate, and the bottom of the second camera 9 has an insertion hole that matches the connecting post. The connecting post is inserted into the connecting hole to complete the connection. The detachable connection between the second camera 9 and the main scale 1 facilitates storage and carrying.

[0030] In one feasible embodiment, the second camera 9 includes a main unit 91, a light shield 92, and a background plate 93. One side of the light shield 92 is connected to the main unit 91, and the other side is connected to the background plate 93. An opening 94 is provided at the connection between the background plate 93 and the light shield 92, allowing fruit to be placed inside the light shield 92. A ring light 911 is used to illuminate the interior of the light shield 92, and the main unit 91 is used to photograph the fruit placed inside the light shield 92. In this embodiment, the light shield 92 helps reduce light leakage at the lens edges, thereby improving image sharpness and detail, and allowing for more accurate fruit data.
