Description

Technical Field

[0001] The present invention relates to the technical field of plant cultivation devices, and in particular to a cultivation device for observing the roots of hydroponic plants. Background Art

[0002] As an important organ for plant absorption, conduction, synthesis, storage, secretion, regulation, fixation and support, the root system plays an important role in plant growth and development. The root system is particularly important for plants. However, the roots growing naturally are deep underground. Due to the complexity of the soil environmental conditions and the opacity of the soil medium, it is very difficult to conduct in-situ observation and measurement. So far, there has been an in-situ root observation system, but this device can only observe the roots around the root tube and cannot observe the entire root morphology and root structure. Therefore, hydroponic experiments have become an important means for root observation.

[0003] Root observation is different from leaf observation. Root observation mainly observes root hairs, branch structures, and growth directions, mainly the three-dimensional shape of the root system, while leaf observation mainly observes the color, texture, stomata, leaf area, and pest and disease spots of the leaves, which are manifested as planar shapes. Therefore, the imaging system for root observation needs to take pictures of the plant roots from multiple angles to form a three-dimensional image.

[0004] Currently, for the observation method of hydroponic plant roots, the plants are mainly cultivated in transparent tubes, and then the imaging system is aligned. The imaging system takes pictures of the plants from multiple angles. This observation method requires moving the plants multiple times, and the operation is very cumbersome. Especially when multiple plants need to be photographed, it makes the researchers need to carry out mechanical activities for a long time, wasting research time. Summary of the Invention

Detailed implementation manners

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment 1

[0041] Refer to Figures 1-6 。

[0042] A culture device for observing the roots of hydroponic plants, comprising: a plurality of culture containers 1, an imaging device 2, a loading part 3, and a driving mechanism 5;

[0043] A plurality of culture containers 1 and the imaging device 2 are both arranged in the loading part 3;

[0044] Among them, a plurality of the culture containers 1 are arranged around the imaging device 2;

[0045] Among them, a driving mechanism 5 is arranged in the loading part 3, and the driving mechanism 5 drives the culture container 1 to rotate around the vertical direction, and drives the culture container 1 to rotate around the imaging device 2, or drives the imaging device 2 to rotate around the vertical direction.

[0046] When observing plant roots, it is mainly necessary to photograph the morphological characteristics of the root hairs, branching structures, growth directions, etc. of the roots. Therefore, the imaging system needs to take pictures and scans from multiple angles to form a three-dimensional image. In addition, in related experiments on observing hydroponic plant roots, multiple plants often need to be cultivated simultaneously for control experiments and to reduce the contingency of the experiment. And each plant needs to be cultivated separately. One is to change the growth environment, and the other is to facilitate the placement of the plant to avoid the interference of adjacent plant roots on the photographed image during shooting. Therefore, in current observation experiments, each plant is cultivated in an independent glass tube. When observation and recording are required, the plant is placed at the shooting position and waits for the imaging device 2 to take pictures. If there is only one plant in an experiment, this observation method is relatively simple. However, experiments often require multiple plants to be carried out simultaneously and need to be photographed multiple times. This results in a large amount of time and energy of the researchers being wasted on placing the plants during the experiment process, and mistakes are inevitable during the process of moving the plants multiple times, resulting in violent shaking of the plants and breakage of fine roots, affecting the absorption of water and nutrients and the accuracy of the experiment.

[0047] In view of the technical problem of the cumbersome above-mentioned observation operation, this embodiment provides a cultivation device capable of efficiently observing roots.

[0048] Firstly, a loading part 3 is provided. Above the loading part 3, a plurality of culture containers 1 are provided. Among them, an imaging device 2 is arranged in the middle of the loading part 3, and the plurality of culture containers 1 are arranged around the imaging device 2; and a driving mechanism 5 is also provided. The driving mechanism 5 drives a single culture container 1 to rotate so that the imaging device 2 can photograph the roots of the plant at different angles. The driving mechanism 5 can also drive the imaging device 2 to rotate or drive the plurality of culture containers 1 to rotate around the imaging device 2 so that the imaging device 2 can photograph the plants in different culture containers 1.

[0049] A supporting floating plate 11 is arranged in the culture container 1. The supporting floating plate 11 is slightly smaller than the culture container 1. The supporting floating plate 11 can rise or fall with the water level. At the same time, the supporting floating plate 11 can only shake slightly in the horizontal direction. A flexible structure such as a sponge is arranged in the supporting floating plate 11 to clamp the plant. The supporting floating plate 11 can prevent the plant from shaking to a certain extent when the container shakes, causing the breakage of the plant roots.

[0050] The following provides several specific settings of the feasible driving mechanism 5:

[0051] 1. The bottom of the imaging device 2 is directly connected to the driving motor 53, and the bottom of each culture container 1 is connected to the driving motor 53. This setting method can most directly achieve the purpose of driving. However, the number of driving motors 53 is too large, the cost is high, and each driving motor 53 needs to be controlled separately, and the control logic is relatively complex.

[0052] 2. The bottom of the imaging device 2 is directly connected to the drive motor 53. The culture container 1 is rotationally connected to the loading part 3 through the connecting shaft 12, and a transmission mechanism is provided on each connecting shaft 12. The transmission mechanism can be a gear cooperating with an open belt, a chain cooperating with a sprocket, or a belt sleeved on the connecting shaft 12, so that each culture container 1 can rotate synchronously. Thus, the culture container 1 can be rotated by one drive motor 53, enabling the imaging device 2 to capture the root systems at different angles. The imaging device 2 can also be fixed, and the transmission mechanism of the culture container 1 is arranged in a loading platform, and then an additional drive is provided to rotate the loading platform, so that multiple culture containers 1 rotate around the imaging device 2.

[0053] The drive motor 53 can be a servo motor or a stepper motor, which can accurately control the rotation angle. At the same time, the drive motor 53 should start slowly to avoid causing violent shaking of the plants when starting suddenly.

[0054] In the culture device of this embodiment, through the arrangement of multiple culture containers 1 around the imaging device 2, the root systems of the remaining plants do not overlap when the imaging device 2 captures each plant, improving the accuracy of the captured image. And there is a definite relative position between the culture container 1 and the imaging device 2. Without the need for researchers to manually move the plants and the culture container 1, only by the automatic operation of the drive mechanism 5, the imaging device 2 can completely capture the root systems of each plant, realizing the automatic capture of the plant root systems and greatly simplifying the operation steps of the relevant experiments for observing the plant root systems.

[0055] Further, corresponding digital labels are provided in the culture container 1, and the imaging device 2 identifies the digital labels to distinguish the plants.

[0056] It should be noted that the digital labels should not block the plant root systems. For this, the digital labels can be set at the bottom of the culture container 1 and face the imaging device 2. When shooting, the imaging device 2 can see both the plant root systems and the digital labels, and the imaging device 2 includes the captured plant root systems in the corresponding digital labels.

[0057] Embodiment 2

[0058] Refer to Figures 1-6 .

[0059] The drive mechanism 5 includes a ring gear 51, a sun gear 52, a first gear 54, and a drive motor 53;

[0060] Wherein, the culture container 1 is rotationally connected to the ring gear 51 through the connecting shaft 12;

[0061] The first gear 54 is arranged on the main shaft of the drive motor 53;

[0062] The first gear 54 meshes with the ring gear 51 and the sun gear 52 simultaneously to form a planetary gear assembly;

[0063] Among them, the ring gear 51 is fixedly connected to the loading part 3, and the sun gear 52 is rotatably connected to the loading part 3.

[0064] In this embodiment, a driving mechanism 5 is provided again. The driving mechanism 5 is configured as a planetary gear structure. Among them, the imaging device 2 is fixedly connected to a sun gear 52. The culture container 1 is rotatably connected to the ring gear 51 through a connecting shaft 12. The first gear 54 is fixed to the main shaft of the driving motor 53 as a planetary gear. The first gear 54 meshes with the sun gear 52 and the ring gear 51 simultaneously. The ring gear 51 is fixedly connected to the loading part 3, and the sun gear 52 is rotatably connected to the loading part 3. At this time, the driving motor 53 drives the first gear 54 to rotate, and the sun gear 52 and the imaging device 2 will rotate, changing the shooting object of the imaging device 2.

[0065] Embodiment 3

[0066] Refer to Figures 1-6 。

[0067] The driving mechanism 5 includes a second gear 55 and a third gear 56;

[0068] The second gear 55 is arranged in the main shaft of the driving motor 53, the third gear 56 is fixedly arranged in the connecting shaft 12, and the second gear 55 meshes with the third gear 56;

[0069] Among them, the first gear 54 and the second gear 55 are rotatably connected to the main shaft of the driving motor 53;

[0070] Among them, a locking ring 57 is arranged between the first gear 54 and the second gear 55;

[0071] Among them, the locking ring 57 is slidably connected to the main shaft of the driving motor 53, and the locking ring 57 rotates synchronously with the main shaft;

[0072] When the locking ring 57 abuts against the first gear 54 or the second gear 55, the first gear 54 or the second gear 55 rotates synchronously with the main shaft;

[0073] It further includes a switching device 6. The switching device 6 is connected to the locking ring 57 and drives the locking ring 57 to slide along the length direction of the main shaft.

[0074] In Example 1, at least two drive motors 53 are required for several drive mechanisms 5 provided, and it is impossible to drive a culture container 1 to rotate independently. In the present application, a plurality of loading containers are provided. For example, eight culture containers 1 are provided. Then, if the drive motor 53 can independently drive a culture container 1 to rotate, the drive motor 53 only needs to provide one-eighth of the power and reduce the rotation times of the remaining non-photographed objects. Although it is not easy for the drive motor 53 to drive the culture container 1 to generate violent shaking, the additional movement will more or less affect the growth of plants, especially for some delicate plants and in relatively precise experiments, it is extremely necessary to minimize unnecessary interference with plants. However, if a drive motor 53 is configured for each culture container 1, the production cost of the device will be greatly increased.

[0075] For this reason, in this embodiment, a second gear 55 and a third gear 56 are additionally provided in the original planetary gear drive mechanism 5 mode. The second gear 55 is also arranged on the main shaft of the drive motor 53, so that the drive motor 53 has two layers of gears, and the first gear 54 and the second gear 55 are rotationally connected to the main shaft of the motor. It can be understood that if the gear is rotationally connected to the shaft, then when the shaft rotates, the gear will not be able to transmit the rotational force of the shaft to the next gear. Further, the third gear 56 is fixedly arranged in the connecting shaft 12 of the culture container 1, that is, two-side gears are formed between the third gear 56 and the ring gear 51. The first gear 54 meshes with the ring gear 51, and the second gear 55 meshes with the third gear 56. However, at this time, both the first gear 54 and the second gear 55 rotate relative to the main shaft of the drive motor 53. Therefore, even if the drive motor 53 is started, the first gear 54 and the second gear 55 cannot complete the transmission, and the sun gear 52 and the third gear 56 will not rotate. Furthermore, in this embodiment, a locking ring 57 is also provided. The locking ring 57 only slides along the axis direction in the main shaft of the drive motor 53 and does not rotate. At this time, when the locking ring 57 abuts against the first gear 54 or the second gear 55, the first gear 54 or the second gear 55 will not be able to rotate relative to the main shaft of the drive motor 53. Thus, when the main shaft rotates, the gear abutted by the locking ring 57 will be able to rotate following the main shaft, thereby transmitting power to the gear meshing with it.

[0076] Friction cone surfaces A571 are provided at both ends of the locking ring 57;

[0077] Locking holes 58 are provided at the centers of the first gear 54 and the second gear 55, and chamfered edges are provided at the ends of the locking holes 58 to form friction cone surfaces B581;

[0078] The end of the locking ring 57 is inserted into the locking hole 58, and the friction conical surface A571 and the friction conical surface B581 are pressed against each other, so that the first gear 54 / the second gear 55, the locking ring 57, and the main shaft of the drive motor 53 rotate synchronously.

[0079] A rubber layer can be provided on the friction conical surface A571 and the friction conical surface B581 to increase the friction force. The cooperation between the two conical surfaces of the friction conical surface A571 and the friction conical surface B581 can obtain a larger contact area, so as to obtain a larger friction force under a rated pressure, and avoid relative sliding between the locking ring 57 and the first gear 54 or the second gear 55.

[0080] The switching device 6 is set as an electromagnet. The electromagnet is a very efficient linear drive device and its cost is much lower than that of a motor. The iron core of the electromagnet is connected to the iron core. When the iron core pops out, the locking ring 57 abuts against the first gear 54, and when the iron core retracts, the locking ring 57 abuts against the second gear 55.

[0081] Furthermore, the switching device 6, the drive motor 53, and the power supply are all fixedly arranged in a connecting part 7. The connecting part 7 is rotatably connected to the sun gear 52 and plays a role in stabilizing the first gear 54, guiding the first gear 54 to rotate around the axis of the sun gear 52.

[0082] It further includes a connecting part 7, and the connecting part 7 is rotatably connected to the sun gear 52. Among them, the switching device 6, the drive motor 53, and the power supply are all fixedly arranged in the connecting part 7.

[0083] Embodiment 4

[0084] Refer to Figure 1 and Figure 2 .

[0085] A lighting component 8 is arranged on the periphery of the plurality of culture containers 1. The lighting component 8 has a plurality of light sources 81, and each light source 81 corresponds to one of the culture containers 1; only the light source 81 corresponding to the culture container 1 to be photographed is turned on to illuminate towards the imaging device 2.

[0086] A mask 9 surrounding the plurality of culture containers 1 is arranged on the periphery of the loading part 3. The mask 9 is made of a light-shielding material, and the lighting component 8 is located inside the mask 9.

[0087] Photographing plant roots is different from ordinary photographing. High-contrast images are required to obtain high-quality images. The lights and background in the laboratory are very likely to affect the photographed picture, causing the photographing system to make wrong judgments.

[0088] In this embodiment, a mask 9 is provided around the loading part 3, that is, around the plurality of culture containers 1. The material of the mask 9 should prevent light from passing through and prevent reflection as much as possible. Specifically, polyester, flocked cloth, or black matte acrylic plate can be used. And the mask 9 should be in a dark color, preferably black, so as to achieve the best light-shielding effect.

[0089] At the same time, a lighting assembly 8 is provided for the plurality of culture containers 1. The lighting assembly 8 has a plurality of light sources 81, and each light source 81 corresponds to a culture container 1. The light source 81 illuminates towards the imaging device 2 behind the culture container 1. The so-called "behind" means extending along the shooting direction of the imaging device 2 with the imaging device 2 as the starting point, and the direction away from the imaging device 2 is the "behind". Therefore, the positional relationship among the imaging device 2, the culture container 1, and the light source 81 is the camera, the culture container 1, and the light source 81 in sequence.

[0090] Furthermore, the plurality of light sources 81 are integrated into one body to form the lighting assembly 8. The loading part 3 can extend multiple sliding rails 82 upward, and the lighting assembly 8 slides along the sliding rails 82. When shooting is required, the lighting assembly 8 is slid to a height at which the plant roots can be illuminated. When shooting is not required, the lighting assembly 8 is lowered, and the lighting assembly 8 avoids the plant roots, facilitating the naked-eye observation by researchers.

[0091] The light passes through the root system and then enters the imaging device 2 through the lighting assembly 8, thereby enhancing the image contrast. At the same time, the mask 9 can absorb stray light, improve the background purity, and enhance the image contrast and signal-to-noise ratio.

[0092] Furthermore, the mask 9 is made of a flexible material, and the top of the mask 9 has a hanging part A92. A supporting part 91 is provided on the periphery of the loading part 3, and a hanging part B93 is provided in the supporting part 91. After the hanging part A92 is connected to the hanging part B93, the culture container 1 is completely covered in the height direction.

[0093] For example, one of the masks 9 is made of flocked cloth. The mask 9 can also be provided with a plurality of circular keels. When shooting is not carried out, the mask 9 is stacked below. When shooting is required, the mask 9 is pulled up so that the mask 9 wraps the culture container 1. The hanging part A92 is provided at the top of the mask 9, and the supporting part 91 is provided on the periphery of the loading part 3. The hanging part B93 is provided above the supporting part 91. The hanging part A92 and the hanging part B93 are set as hook-shaped structures. The hanging part A92 and the hanging part B93 are hooked to prevent the flexible mask 9 from falling. With this design, the mask 9 can achieve a very convenient use effect at a very low cost.
