Description

Technical Field

[0001] This invention relates to the field of plant seed testing and provides a rotating photographic platform for detecting the uniformity of rice seed coating. Background Technology

[0002] Seed coating refers to applying a layer of protective agents, nutrients, or regulators to the surface of seeds to improve their germination performance, disease resistance, and sowing adaptability. For rice seeds, the uniformity of the coating directly affects the germination rate, seedling growth consistency, and field management effectiveness. Uneven seed coating may result in some seeds lacking protection or nutrients, while others may have excessively thick coatings, thus impacting sowing efficiency and crop yield.

[0003] Currently, the testing of rice seed coating uniformity relies heavily on manual observation and photographic recording. During the process, workers need to evenly spread the seeds on a flat surface, visually observe the seed coating, and take photos using a camera or mobile phone for recording and subsequent analysis. This process requires workers to inspect each seed individually or perform local sampling, recording the coating condition of each batch of seeds to assess coating uniformity.

[0004] However, existing methods for manually detecting seed coating uniformity have many drawbacks. Firstly, manual observation is inefficient, especially with large batches of seeds, as it is time-consuming and prone to oversights. Secondly, manual recording relies on subjective judgment, making accurate and quantifiable assessments difficult, resulting in poor stability and repeatability of the test results. Therefore, a simple, efficient, and accurate detection device for seed coating uniformity is needed to overcome the shortcomings of existing manual detection methods. Utility Model Content

[0005] To address the aforementioned deficiencies, the present invention aims to provide a rotating photographic platform for detecting the uniformity of rice seed coating. This is intended to solve the problems mentioned in the background art. The device includes a guide rail vertically mounted on a base, with several movable seats slidably connected to the guide rail. These movable seats can slide along the vertical direction of the guide rail and can be locked in position on the guide rail. A camera mount, a supplementary light mount, and a turntable mount are respectively mounted on the guide rail from top to bottom via the multiple movable seats. The turntable is rotatably connected to the turntable mount and can tilt and rotate in the direction facing or away from the guide rail, maintaining its tilted state.

[0006] Furthermore, the movable seat has a gear groove on the side near the guide rail, and a movable knob is rotatably mounted on the movable seat; a shaft passing through the interior of the movable seat is fixedly connected to the movable knob, and a gear located in the gear groove is installed at the end of the shaft; a scale rail that meshes with the gear is provided on the guide rail.

[0007] Furthermore, a locking knob is rotatably mounted on the movable seat; a push rod corresponding to the guide rail is fixedly connected to the locking knob, and the push rod is threadedly engaged with the movable seat. When the locking knob is rotated, the push rod can press against the guide rail, thereby fixing the movable seat in the designated position on the guide rail.

[0008] Furthermore, the supplementary light fixture is provided with an annular mounting base, the center of which coincides with the lens axis of the industrial camera above.

[0009] Furthermore, the shadowless lamp installed on the supplementary lighting bracket is a ring lamp.

[0010] Furthermore, the turntable includes a turntable motor, and the top of the turntable is provided with a rotatable platform. The top of the platform is provided with a placement hole, which is a circular recess with a height of 2-3mm.

[0012] Furthermore, the turntable is provided with side platforms on both sides, and the side platforms are provided with several limiting holes. The turntable frame is provided with retractable positioning beads corresponding to the limiting holes.

[0013] This invention allows for flexible adjustment of the height and position of the industrial camera, shadowless lamp, and turntable via a movable base to adapt to different shooting and testing conditions. The turntable can rotate and tilt, enabling rice seeds to be presented from multiple angles under the industrial camera lens, obtaining more comprehensive seed coating information. The ring-shaped shadowless lamp installed on the supplementary lighting bracket provides uniform lighting, prevents blind spots in shooting, better presents the seed coating state, and improves the accuracy and reliability of testing.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0025] See Figure 1-6The purpose of this utility model is to provide a rotating photographic platform for detecting the uniformity of rice seed coating, including a guide rail 2 mounted on a base 01. The guide rail 2 is vertically mounted on the base 01, which can be mounted on a test bench to fix the entire device. Several movable seats 3 are slidably connected to the guide rail 2. The movable seats 3 can slide along the vertical direction of the guide rail 2 and can be locked in position on the guide rail 2. Specifically, there are three movable seats 3 on the guide rail 2, and a camera mount 5, a supplementary light mount 6, and a turntable mount 7 are respectively mounted on the three movable seats 3. The camera mount 5, supplementary light mount 6, and turntable mount 7 are arranged sequentially from top to bottom. An industrial camera 1, a shadowless lamp 9, and a turntable 8 are respectively mounted on the camera mount 5, supplementary light mount 6, and turntable mount 7. Specifically, the turntable 8 is rotatably connected to the turntable mount 7 and can tilt and rotate in a direction facing or away from the guide rail 2.

[0026] The turntable 8 in this technical solution is a common small turntable device on the market. The turntable 8 can drive the rotation and rotation of the object on its top. Its working principle mainly relies on the transmission system composed of components such as motor, reducer, transmission shaft and bearing to work together to drive the turntable 8.

[0027] Therefore, the operator can adjust the height and position of the industrial camera 1, the shadowless lamp 9, and the turntable 8 via the movable base 3 to adjust the lighting environment, magnification, and other conditions more conducive to shooting and testing. In practical applications, the turntable 8 can be manually adjusted to a horizontal position by the operator, at which point rice seeds can be spread flat on the rotatable surface of the turntable 8.

[0028] The tilt of the turntable 8 can be adjusted on the turntable frame 7. After adjustment, the top surface of the turntable 8 is tilted towards the lens of the industrial camera 1. When the turntable 8 is in operation, it can drive the upper platform to rotate, so that the rice seeds on the platform can be presented under the lens at different angles, and multi-angle shooting can be completed.

[0029] Preferably, the movable seat 3 has a gear groove on the side near the guide rail 2. A moving knob 31 and a locking knob 32 are rotatably mounted on the movable seat 3. A shaft passing through the interior of the movable seat 3 is fixedly connected to the moving knob 31, and a gear 311 is installed at the end of the shaft in the gear groove. A guide rail 4, which meshes with the gear 311, is provided on the guide rail 2. When the moving knob 31 is rotated, the shaft drives the gear 311 to rotate, allowing the movable seat 3 to move along the height of the guide rail 2. A push rod 321 corresponding to the guide rail 2 is fixedly connected to the locking knob 32. The push rod 321 is threadedly engaged with the movable seat 3. When the locking knob 32 is rotated, the push rod 321 presses against the guide rail 2, locking the movable seat 3 in a fixed position on the guide rail 2.

[0030] Preferably, one end of the fill light holder 6 is detachably mounted to the movable base 3 by bolts. The other end of the fill light holder 6 is provided with an annular mounting base, the center of which coincides with the lens axis of the industrial camera 1 above.

[0031] Preferably, the shadowless lamp 9 installed on the supplementary lighting bracket 6 is a ring lamp. This ensures uniform lighting, better presents the seed coating state, and prevents blind spots in the shooting.

[0032] Preferably, the turntable 8 includes a turntable motor 81, which is a common stepper motor. The top of the turntable 8 has a rotatable platform, and the top of the platform has a placement hole 82. The placement hole 82 is a circular recess with a height of 2-3 mm and a diameter of 3-5 cm. Workers can pile rice seeds on top of the placement hole 82, and then manually or using a scraper or other tools to remove excess seeds, leaving only a single layer of seeds in the placement hole 82. This completes the preparation work before seed imaging and testing.

[0033] Preferably, one end of the turntable bracket 7 is detachably installed to the movable seat 3 via bolts. The other end of the turntable bracket 7 has a forked structure, and the turntable 8 is rotatably connected between the forked structures. Specifically, both sides of the turntable 8 are provided with side platforms 82, and the two side platforms 82 are respectively hinged to the two forks of the forked structure. Further, the side platforms 83 are provided with a plurality of limiting holes 84, and the turntable bracket 7 is provided with retractable positioning beads 832 corresponding to the limiting holes 84. When the turntable 8 is tilted to a preset angle, the positioning beads 832 will engage with the limiting holes 84 of the side platforms 82, thereby maintaining the tilted state of the turntable 8. It is understood that there are multiple implementation schemes for maintaining the tilted state of the turntable 8. In a more preferred implementation scheme, the tilted state of the turntable 8 can be maintained by means of a pin insertion.

[0034] In summary, during actual use, the staff first installs the base 01 on a suitable test bench to ensure the stability of the entire device. Based on the actual shooting and testing requirements, the staff rotates the movable knob 31 on the movable base 3, causing the shaft to drive the gear 311 to rotate on the guide rail 4, thereby moving the movable base 3 along the height direction of the guide rail 2, adjusting the camera mount 5, the fill light mount 6, and the turntable mount 7 to the appropriate height.

[0035] Manually adjust the turntable 8 to a horizontal position, spread the rice seeds evenly on top of the placement hole 82, and use a scraper or other tools to remove excess seeds, leaving only a single layer of seeds in the placement hole 82. Then, adjust the tilt of the turntable 8 as needed, so that the top surface of the turntable 8 is angled towards the lens of the industrial camera 1. When the turntable 8 is tilted to the preset angle, the positioning bead 832 engages with the limiting hole 84 of the side platform 82, maintaining the tilted state of the turntable 8. Finally, start the turntable motor 81, and the turntable 8 drives the upper platform to rotate, allowing the rice seeds spread on the platform to be presented at different angles under the lens of the industrial camera 1, completing multi-angle shooting.

[0036] Therefore, this device can flexibly adjust the height and position of the industrial camera 1, the shadowless lamp 9, and the turntable 8 via the movable base 3 to adapt to different shooting and detection conditions; the turntable 8 can rotate and tilt, so that rice seeds can be presented under the lens of the industrial camera 1 from multiple angles, obtaining more comprehensive seed coating information; the ring shadowless lamp 9 installed on the supplementary light fixture 6 can provide a uniform lighting effect, prevent shooting blind spots, better present the seed coating state, and improve the accuracy and reliability of detection.

[0037] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
