[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] See also Figure 1 The embodiment of the present invention discloses a plant factory vegetable seedling raising device, the device comprises a controller (not shown in the figure), a flexible tank, a reciprocating motor, an elastic band, and a camera, the reciprocating motor is respectively connected to the two ends of the elastic band to form a soil loosening mechanism, and the soil loosening mechanism is arranged on the circumference of the flexible tank; the controller is respectively connected to the camera and the reciprocating motor for communication; The camera is used to capture the growth image of the seedlings in the flexible tank and send the growth image to the controller; The controller is used to obtain target retraction and extension parameters according to the growth image analysis, and send the target retraction and extension parameters to the retraction and discharge motor; wherein the target retraction and extension parameters include contraction length, contraction speed, relaxation speed, and retraction and extension times; The retractable and discharging motor is used to pull the two ends of the elastic band according to the target retractable and discharging parameters to change the force applied by the elastic band to the flexible tank, thereby reducing the density of the soil in the flexible tank due to the change in the magnitude of the above-mentioned force.

[0023] like Figure 1 As shown, the plant factory vegetable seedling raising device of the present invention realizes an intelligent soil loosening mechanism by integrating key components such as a controller, a flexible tank, a retractable electric motor, an elastic band and a camera. The specific working principle is as follows: The camera is installed at an appropriate location to take regular or real-time images of the growth of the seedlings in the flexible pot. These images capture information such as the growth status of the seedlings, the surface conditions of the soil, and possible changes in soil compactness. The controller has built-in image processing and analysis algorithms that can evaluate the growth needs and soil conditions of the seedlings based on the received image data, and then calculate the target retraction and release parameters, including the length of the elastic band that needs to be retracted, the speed of retraction and relaxation, and the number of retraction and release. These parameters are designed to optimize the soil structure and promote the growth of the seedlings. The retracting and discharging motor can accurately control the two ends of the elastic band to retract or relax according to the instructions sent by the controller. When the elastic band contracts, it applies a greater force to the flexible pot, causing the soil in the pot to be squeezed and loosened; when the elastic band relaxes, the soil is restored and may become looser due to the previous loosening. Through this periodic contraction and relaxation action, the soil density is effectively reduced, the air permeability and water retention of the soil are increased, and a more suitable growth environment is provided for the seedlings.

[0024] The device of the present invention realizes real-time monitoring and intelligent regulation of the seedling growth environment, greatly improving the automation and intelligence level of the seedling cultivation process; and, through the dynamic adjustment of the elastic band, the soil density is effectively controlled, which not only avoids the obstruction of root growth caused by too compact soil, but also prevents the seedlings from being unstable due to too loose soil. The air permeability and water retention of the soil are improved, which is beneficial to the root development and nutrient absorption of the seedlings.

[0025] Optionally, the bottoms of several of the flexible tanks are detachably fixedly connected to the base, the retractable discharge motor is fixedly connected to the outer wall of the flexible tank, and the elastic band is fixedly connected to the outer wall of the flexible tank at least at one point.

[0026] In this embodiment, the bottom of the flexible tank is detachably fixedly connected to the base, which is convenient for removing the cultivated seedlings and can prevent the flexible tank from collapsing during the loosening process. The fixing point of the elastic band and the outer wall of the flexible tank is preferably located directly opposite the transceiver motor, that is, the fixing point of the transceiver motor, the fixing point of the elastic band and the center of the flexible tank are all in a straight line.

[0027] Optionally, the flexible tank is also provided with a crawling track, and the retractable discharge motor can move up and down on the crawling track.

[0028] In this embodiment, the creeping track mainly includes a first creeping tooth and a limiting groove, the retractable discharge motor includes a second creeping tooth and a locking protrusion, the second creeping tooth meshes with the first creeping tooth, the locking protrusion is movably engaged in the limiting groove, and the retractable discharge motor can move up and down on the creeping track by driving the second creeping tooth to rotate. In this way, the retractable discharge motor can perform the above-mentioned loosening action on the flexible tank at different positions, such as Figure 2As shown in the figure, due to the different angles and positions of the loosening action, the obtained loosening effect and loosening depth are different.

[0029] Optionally, the controller is used to obtain target retraction and extension parameters according to the growth image analysis, including: The controller further includes an image processing module, a first analysis and decision module, and a second analysis and decision module; The image processing module is used to receive the growth image sent by the camera, perform preprocessing and feature extraction on the growth image, and obtain seedling growth state characteristics and soil surface characteristics; The first analysis and decision module is used to predict soil density based on the soil surface characteristics and fertilizer and water application data; wherein the fertilizer and water application data includes fertilizer application type and cumulative fertilizer and water addition amounts; The second analysis and decision module is used to analyze and calculate the target soil density based on the seedling growth status characteristics and the soil density, and to deduce the target retraction and release parameters based on the soil density; wherein the target retraction and release parameters include contraction length, contraction speed, relaxation speed, and retraction and release times.

[0030] In this embodiment, the controller of the present invention integrates an image processing module, a first analysis and decision module, and a second analysis and decision module. The image processing module can extract the seedling growth state characteristics and soil surface characteristics from the growth image. Then, the first analysis and decision module retrieves the relevant information of the factory applying fertilizer and water to the flexible tank, including the fertilizer application type and the cumulative amount of fertilizer and water added, and combines the soil surface characteristics to predict the soil density inside the flexible tank. Then, the second analysis and decision module analyzes the target soil density suitable for the current seedling growth state characteristics based on the seedling growth state characteristics and soil density, and calculates the target retraction and release parameters corresponding to the target soil density, that is, by controlling the retracting and discharging motor to perform multiple squeezing and relaxing operations on the flexible tank according to the target retraction and release parameters, the soil in the flexible tank can be loosened to the target soil density.

[0031] The first analysis and decision module and the second analysis and decision module can both be constructed based on Transformer, and mainly include an input layer, an encoder, a decoder and an output layer. The present invention does not limit the specific structure and training process.

[0032] Optionally, the controller further includes a third analysis and decision module; The third analysis and decision module is used to predict the root depth of the seedling according to the growth status characteristics of the seedling; The second analysis and decision module is used to analyze and calculate the target soil density based on the seedling growth state characteristics and the soil density, including: The first module in the second analysis and decision module analyzes and calculates the target soil density based on the growth status characteristics of the seedlings and the soil density, and the second module in the second analysis and decision module predicts the target retraction and release parameters based on the root depth, the target soil density and the size data of the flexible tank. The target retraction and release parameters include the contraction length, contraction speed, relaxation speed, retraction times and the height of the retractable motor.

[0033] In this embodiment, a third analysis and decision module is further provided in the controller, which is used to predict the root depth of the seedlings according to the growth status characteristics of the seedlings. This process mainly predicts the root depth by the type and plant height of the seedlings. The deeper the root depth, the lower the height to which the electric motor needs to be lowered. This is beneficial to reducing the density of the soil in which the overall root system is located.

[0034] At the same time, the second analysis and decision-making module includes a first module and a second module. The first module predicts the target soil density in the flexible tank (which represents the overall soil density in the flexible tank) based on the growth status characteristics of the seedlings and the soil density. The second module predicts the target retraction and release parameters based on the root depth, target soil density and the size data of the flexible tank (mainly the three-dimensional size of the outer contour). In addition to the contraction length, contraction speed, relaxation speed, and number of retractions and releases, it also includes the height of the retraction and discharge motor.

[0035] Among them, the first module and the second module are also preferably built based on Transformer, and the two are integrated into the second analysis and decision-making module. The specific construction and integration process will not be repeated here.

[0036] Optionally, the camera is arranged on a horizontal track, and can change its position on the horizontal track to achieve shooting of multiple flexible tanks.

[0037] In this embodiment, since the loosening operation is not real-time but is performed when necessary, and generally only two or three times are required in the entire seedling raising process, the present invention does not configure a camera for each flexible tank, but configures one camera for multiple flexible tanks, and realizes shooting of multiple flexible tanks by changing the position of the camera on the horizontal track.

[0038] Optionally, the retractable motor includes a motor and a retractable shaft, two ends of the elastic band are respectively connected to different positions of the retractable shaft, and the two ends of the elastic band are respectively located on both sides of the retractable shaft when stretched.

[0039] In this embodiment, if Figure 3As shown, the two ends of the elastic band are respectively fixed on the retractable shaft. When the motor drives the retractable shaft to rotate forward, the elastic band is wound around the retractable shaft, which can achieve the tightening of the elastic band, so that it exerts a greater winding force on the flexible tank and crushes the compacted soil in the flexible tank; when the motor drives the retractable shaft to rotate reversely, the elastic band gradually separates from the retractable shaft, which can achieve the loosening of the elastic band, so that it exerts a smaller winding force on the flexible tank. Repeating the tightening and loosening actions many times can achieve the effect of loosening the soil in the flexible tank. Compared with directly using tools to enter the flexible tank to loosen the soil, it will not damage the plant body and root system of the seedlings.
