Description

Technical Field

[0001] This invention belongs to the field of root monitoring technology, and more specifically, relates to a plant root image sensor and a plant root monitoring device. Background Technology

[0002] The root system is the core organ for plants to absorb water and nutrients and sense the soil environment. The growth morphology, distribution range, and developmental status of the root system directly determine the plant's growth vigor, stress resistance, yield, and quality. In modern agricultural planting, plant physiological research, and ecological vegetation cultivation, real-time and precise monitoring and refined maintenance of plant roots are of paramount importance. With the rapid development of smart agriculture and precision planting technologies, in-situ, non-destructive, and dynamic root monitoring and root zone precision fertilization technologies have become the core direction of industry technology research and development.

[0003] Traditional monitoring equipment can only collect images and detect data at local points of the root system. It cannot achieve overall and comprehensive observation of the plant root system. It is difficult to fully capture the comprehensive characteristics of the root system, such as growth distribution, branching structure, and growth changes. The monitoring data is one-sided and has low accuracy, which cannot meet the needs of scientific research and precision planting for multi-dimensional and comprehensive root system monitoring.

However, under the premise that those skilled in the art understand the concept of the present invention, they can implement the above-mentioned specific forms and arrangements in a well-known manner.

[0023] When a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0024] The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself. The terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0025] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0027] The present invention will now describe a plant root image sensor 300.

[0028] like Figure 1 As shown, the present invention provides a plant root image sensor, including a substrate 10, an image sensor body 20, a flash lamp 30, and a controller 40. Mounting plates 11 are formed at both ends of the substrate 10. There are eight image sensor bodies 20, of which four rectangular arrays are arranged on one side of the substrate 10 and the other four rectangular arrays are arranged on the other side of the substrate 10, for capturing and monitoring the plant root system on both sides of the substrate 10. The flash lamps 30 are arranged on both sides of the substrate 10 and spaced apart between the image sensor bodies 20, for illuminating when the image sensor bodies 20 are capturing images. The controller 40 is fixedly mounted on the substrate 10.

[0029] Compared with the prior art, the plant root image sensor 300 provided by this invention includes a substrate 10, an image sensor body 20, a flash lamp 30, and a controller 40. By setting four rectangular arrays of image sensor bodies 20 on each of the front and back sides of the substrate 10, and cooperating with the spaced flash lamps 30 for supplementary lighting, it is possible to realize full-area, multi-angle imaging of the root system on both sides of the substrate 10, improve the coverage and completeness of root image acquisition, capture the growth morphology and distribution characteristics of the root system, and improve the accuracy and comprehensiveness of monitoring data. The controller 40 is fixedly installed on the substrate 10 and is used to control the start and stop of the image sensor body 20, the shooting frequency, and the opening and closing of the flash lamp 30. At the same time, it can transmit the acquired image data to the outside.

[0030] Based on the same inventive concept, such as Figures 2 to 11 As shown in the figure, this application embodiment also provides a plant root monitoring device, including a buried casing 100, a monitoring box 200, the aforementioned plant root image sensor 300, and a soil-applying fertilization mechanism 400; the buried casing 100 is made of transparent material and is partially buried on one side of the plant roots, and the buried casing 100 has a first chamber 101, a second chamber 102, and a third chamber 103. Several circular holes 110 are arrayed on both side walls of the buried casing 100, and a retaining sleeve 120 is fixed inside each circular hole 110. One end of the retaining sleeve 120 is provided with a retaining block 130 for sealing one end of the retaining sleeve 120; the monitoring box 200 is made of transparent material and is embedded in the second chamber 102; the aforementioned plant root image sensor 300 is fixed to the monitoring box by fasteners on the mounting plate 11. Within 200; the soil-inserting fertilization mechanism 400 has two sets with identical structures, installed in the first chamber 101 and the second chamber 102 respectively; wherein, the soil-inserting fertilization mechanism 400 includes a first driver 410, a first threaded rod 420, a fertilization frame 430 and a soil-inserting fertilization component 440; the first driver 410 is installed on the top wall of the buried casing 100; the first threaded rod 420 is rotatably disposed in the first chamber 101, and the first threaded rod 420 and the first driver 410 are connected in a transmission manner; the fertilization frame 430 is sleeved and threadedly connected to the first threaded rod 420; the soil-inserting fertilization component 440 is installed on the fertilization frame 430 for inserting into the soil and completing the soil-inserting fertilization action; when the first driver 410 drives the first threaded rod 420 to rotate, it can drive the fertilization frame 430 to rise and fall left and right, thereby adjusting the position of the fertilization operation.

[0031] It should be noted that the entire buried casing 100 is made of transparent material, such as glass or acrylic. When in use, it is partially buried in the soil on one side of the plant roots. The buried casing 100 has a first chamber 101, a second chamber 102 and a third chamber 103. Several round holes 110 are arrayed on both sides of the buried casing 100. A soil retaining sleeve 120 is fixed in the round hole 110. A soil retaining block 130 is provided at the outer end of the soil retaining sleeve 120 to block the port of the soil retaining sleeve 120 and prevent soil from entering the casing. The transparent casing wall and the soil retaining structure will not obstruct the acquisition of root images. In addition, the monitoring box 200 is made of transparent material, such as glass or acrylic, and is embedded in the second chamber 102 of the embedded housing 100; the plant root image sensor 300 is fixedly installed inside the monitoring box 200 by fasteners on the mounting plate 11. The monitoring box 200 can protect the sensor and prevent soil moisture and impurities from affecting the performance of the device.

[0032] Compared with the prior art, the plant root monitoring device provided by this invention integrates a plant root image sensor 300 into a transparent embedded housing 100, which enables in-situ non-destructive monitoring after being buried in the soil. At the same time, two sets of soil-inserting fertilization mechanisms 400 are set up. Based on the root monitoring data, the fertilization frame 430 is driven to rise and fall, and the soil-inserting cylinder 444 is driven into the soil in the root zone to push the fertilizer into the surrounding soil. Compared with the previous method of simply sprinkling fertilizer on the soil, the fertilizer can be fully utilized, thereby realizing the integrated operation of monitoring and fertilization maintenance.

[0033] like Figure 8 As shown, in a specific embodiment of a plant root monitoring device provided by this invention, the fertilizer applicator 430 includes a horizontal plate 431 and a vertical plate 432, which are integrally formed. The horizontal plate 431 and the vertical plate 432 are threadedly connected to the first threaded rod 420. The soil-inserting fertilizer application component 440 includes a second driver 441, a second threaded rod 442, a translation frame 443, a soil-inserting cylinder 444, and a fertilizer-pushing component 445. The second driver 441 is mounted on the horizontal plate 431, and... The output end of the second driver 441 passes through the horizontal plate 431 and is connected to the second threaded rod 442. The translation frame 443 is sleeved and threadedly connected to the second threaded rod 442. When the second driver 441 drives the second threaded rod 442 to rotate, it can drive the translation frame 443 to move in the up and down direction, thereby continuing to adjust the soil fertilization position. The soil inlet cylinder 444 is movably mounted on the translation frame 443. The fertilizer pushing assembly 445 is installed on the translation frame 443 to push the fertilizer in the soil inlet cylinder 444 into the soil.

[0034] like Figure 9As shown, in a specific embodiment of a plant root monitoring device provided in this invention, an arc groove 4431 is provided on the translation frame 443, a soil insertion cylinder 444 is inserted into the arc groove 4431, and a guide plate 4441 is formed at the bottom of the soil insertion cylinder 444. An expansion joint 450 is connected between the guide plate 4441 and the translation frame 443. When the expansion joint 450 extends or retracts, it can pull the soil-inserting cylinder 444 to move along the trajectory of the arc groove 4431, so that the end of the soil-inserting cylinder 444 passes through the round hole 110 of the side wall of the buried sleeve 100 and penetrates into the surrounding soil, thus completing the soil-inserting action and entering the soil to prepare for fertilization.

[0035] like Figure 8 and Figure 9 As shown, in a specific embodiment of a plant root monitoring device provided in this invention, the fertilizer pushing component 445 includes a third driver, a third threaded rod 4451, and a push plate 4452. The third driver is fixed on the bottom wall of the soil inlet cylinder 444. The third threaded rod 4451 and the output end of the third driver are fixedly connected. A guide groove is provided on the side wall of the soil inlet cylinder 444. A guide block is formed on the push plate 4452. The push plate 4452 is disposed in the soil inlet cylinder 444 and is threadedly connected to the third threaded rod 4451. The guide block is disposed in the guide groove.

[0036] It should be noted that when the third drive rotates the third threaded rod 4451, the push plate 4452 moves axially along the guide groove, pushing the fertilizer that has entered the soil inlet cylinder 444 out of the cylinder opening and into the target soil area to complete the fertilization.

[0037] like Figure 8 and Figure 10 As shown, in a specific embodiment of a plant root monitoring device provided in this invention, the soil-feeding mechanism 400 further includes a fertilizer dispensing cylinder 460, which is fixed on a horizontal plate 431. The bottom end of the fertilizer dispensing cylinder 460 is rotatably provided with a fertilizer drop cover 461. A fourth driver 462 is provided on the top wall of the fertilizer dispensing cylinder 460. The output end of the fourth driver 462 is connected to the fertilizer drop cover 461, thereby driving the fertilizer drop cover 461 to rotate. Both the fertilizer drop cover 461 and the soil-feeding cylinder 444 are provided with interfaces, and telescopic corrugated pipes 470 are connected to the two interfaces to adapt to the position changes of the soil-feeding cylinder 444 and ensure the continuity of the fertilizer delivery path.

[0038] like Figure 10 As shown, in a specific embodiment of a plant root monitoring device provided in this invention, the fertilizer cover 461 has a plurality of protrusions 463 arranged in a circular array. When the fertilizer cover 461 rotates, the protrusions 463 can disturb the fertilizer in the fertilizer cylinder 460, preventing the fertilizer from clumping or blocking, and ensuring that the fertilizer falls smoothly and enters the soil inlet cylinder 444 through the telescopic corrugated pipe 470.

[0039] like Figure 8 As shown, in a specific embodiment of a plant root monitoring device provided in this invention, a cleaning groove 4432 is provided on the translation frame 443, and an insert plate 480 is movably inserted into the cleaning groove 4432. Brush bristles 481 are connected to both sides of the insert plate 480, and the brush bristles 481 can contact the side walls of the chamber, thereby facilitating the cleaning of the side walls of the first chamber 101 or the second chamber 102. Wheel plates 482 are provided at both ends of the insert plate 480, and tension pulleys 483 are provided on the upper and lower sides of the wheel plates 482. The tension pulleys 483 on both sides of the wheel plates 482 abut against the other side walls of the first chamber 101 or the second chamber 102.

[0040] It should be noted that when the translation frame 443 moves along the numerical direction, it can drive the insertion plate 480 to move synchronously. The brush bristles 481 wipe the side wall of the chamber to clean the water vapor and dust attached to the inner wall, ensuring the clarity of image acquisition. The tension pulley 483 can ensure the stability of the insertion plate 480 during the movement process, so that the brush bristles 481 always fit the inner wall.

[0041] like Figure 4 and Figure 5 As shown, in a specific embodiment of a plant root monitoring device provided in this invention, recessed grooves 140 and through grooves 150 are provided on the two side walls of the embedded casing 100, and the two side walls of the embedded casing 100 are sealed with cover plates 160 by fasteners to enclose the outer side of the recessed grooves 140. The recessed grooves 140 and through grooves 150 are connected, and a pushing member 500 is placed in the recessed grooves 140 and through grooves 150. The pushing member 500 includes a pulling block 510, a through block 520 and a triangular block 530. The pulling block 510 and the through block 520... 0 and triangular block 530 are integrally formed, and pull block 510 is placed on the outer side of the top wall of embedded sleeve 100. Through block 520 is slidably set in through groove 150. Triangular block 530 is set in recessed groove 140. Slots 531 are opened on both sides of triangular block 530. Several rectangular blocks 540 are limited in slots 531. An anchor post 550 is fixed on each rectangular block 540. Temperature and humidity sensor 560 is set on the anchor post 550. Several through parts 570 are set in recessed groove 140. Anchor post 550 is limited in through parts 570.

[0042] When in use, pulling the pull block 510 upwards will cause the entire pusher 500 to move upwards along the through groove 150. As the triangular block 530 moves upwards, the slot 531 on its side wall pushes the torque block 540 outwards, thereby causing the anchor column 550 and the temperature and humidity sensor 560 to pass outwards through the side wall of the embedded housing 100 and insert into the surrounding soil, thus realizing in-situ detection of soil temperature and humidity.

[0043] like Figure 5 and Figure 6As shown, in a specific embodiment of a plant root monitoring device provided in this invention, the through block 520 has top grooves 521 on both sides, and two top rods 210 are rotatably arranged on both sides of the monitoring box 200. A tension spring 220 is connected between the two top rods 210 on the same side. When the through block 520 is continuously pulled upward, and the top rod 210 is inserted into the top groove 521, the tension of the tension spring 220 keeps the top rod 210 in the locked state, thereby fixing the position of the pusher 500 and ensuring that the temperature and humidity sensor 560 and the anchor post 550 are stably inserted into the soil and maintain the detection state.

[0044] The working process of this device is as follows: When in use, the buried box 100 is buried in the soil on one side of the root of the target plant. When the plant roots grow to the perimeter of the box, the plant root image sensor 300, through the image sensor bodies 20 on both sides and the flash lamp 30, performs full-area imaging and acquisition of image data such as root growth morphology and distribution. At the same time, the pusher 500 can be pulled to insert the temperature and humidity sensor 560 into the soil, and the soil temperature and humidity parameters in the root zone are collected simultaneously to achieve multi-dimensional monitoring.

[0045] When fertilization is required, the first driver 410 drives the first threaded rod 420 to rotate, moving the fertilizer applicator 430 to the target position; the second driver 441 drives the second threaded rod 442 to rotate, moving the translation frame 443 horizontally to the final target position; then the telescopic device 450 moves, pulling the soil inlet cylinder 444 along the arc groove 4431 and inserting it into the soil through the retaining sleeve 120 in the round hole 110; the fourth driver 462 drives the fertilizer drop cover 461 to rotate, and the fertilizer in the fertilizer discharge cylinder 460 falls into the soil inlet cylinder 444 through the telescopic corrugated pipe 470; finally, the third driver drives the push plate 4452 to move outward, pushing the fertilizer into the soil to complete the precision fertilization operation; after the operation is completed, all components are reset, and the soil inlet cylinder 444 is retracted into the housing.

[0046] In addition, during the movement of the translation frame 443, the insertion plate 480 and brush 481 can wipe the inner wall of the cavity to maintain the cleanliness of the transparent wall and ensure the image acquisition effect.
