The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The embodiment of the present invention provides a rice planting box, such as Figure 1-14 As shown, the rice planting box includes: a water tank 1 installed on a base and a box body 2 fixedly installed on the water tank 1 for rice seedling cultivation; a partition 3 fixedly installed in the box body 2 and separating the box body 2 to form a plurality of seedling cultivation cavities, and a plurality of seedling cultivation cavities are each provided with a seedling cultivation tray 4; a drainage pipe 5 fixedly installed on the top of the seedling cultivation cavity for watering rice; a U-shaped water pipe 6 installed on one side of the box body 2, the U-shaped water pipe 6 being connected to the drainage pipe 5; a solenoid valve 7 mounted on the drainage pipe 5; a water pump 8 installed on the base, the drainage end of the water pump 8 being connected to the U-shaped water pipe 6; and a mixing mechanism provided on the water tank 1 for mixing nutrients.

[0021] In this embodiment, during operation, the water in the water tank 1 is extracted and pressurized by a water pump 8, and then pumped to a U-shaped water pipe 6. The U-shaped water pipe 6 serves as a distribution pipe for irrigation water and is connected to a drainage pipe 5 at the top of each layer of the seedling chamber. Each drainage pipe 5 is provided with a solenoid valve 7, which is a key component for controlling the irrigation amount. When irrigation begins, the controller 41 opens the solenoid valves 7 corresponding to each layer of the seedling chamber in turn, and controls the opening degree or opening time of each solenoid valve 7 according to the preset irrigation amount or time, so as to accurately adjust the amount of water obtained by each layer of the seedling tray 4. In this way, even the seedling tray 4 far away from the front end of the water pipe can The same amount of water as the seedling tray 4 near the front end of the water pipe is obtained, ensuring the uniformity of water flow distribution. At the same time, the mixing mechanism on the water tank 1 can mix an appropriate amount of nutrients in the irrigation water to provide necessary nutrients for rice growth. Through the precise control of the solenoid valve 7, each layer of the seedling tray 4 can obtain a uniform and appropriate amount of water, solving the problem of uneven water flow distribution in traditional irrigation methods. Through the introduction of the solenoid valve 7, the irrigation amount can be accurately controlled to each layer of the seedling tray 4, improving the accuracy and efficiency of irrigation. At the same time, the controller 41 can adjust the irrigation amount according to the actual needs of different seedling trays 4, and has strong adaptability and flexibility.

[0022] In a further preferred embodiment of the present invention, a support frame 9 for preventing rice from lodging is provided above the seedling tray 4, a fill light 10 is installed on the top of the seedling cavity, and a temperature and humidity sensor 11 for monitoring the temperature and humidity in the box 2 is installed in the box 2.

[0023] In this embodiment, when the rice is growing, the support frame 9 provides necessary support to prevent lodging, the fill light 10 provides simulated sunlight when needed to promote photosynthesis, the temperature and humidity sensor 11 monitors and feeds back the environmental conditions in the box 2 in real time, and the control system controller 41 adjusts the irrigation amount, light intensity, etc. according to these data to create an optimal growth environment for the rice. The introduction of the support frame 9 effectively prevents the rice from lodging due to excessive growth or its own factors, thereby improving the wind resistance and stability of the rice.

[0024] In a further preferred embodiment of the present invention, a guide frame 12 is fixedly installed on one side of the seedling raising cavity, and a plurality of rollers 13 are fixedly installed on the bottom of the inner wall of the guide frame 12, and the plurality of rollers 13 are all in contact with the support plate of the seedling raising tray 4.

[0025] In this embodiment, when it is necessary to take out the seedling tray 4 for transplanting, inspection or other operations, the threaded tube 49 drives the seedling tray 4 to move, and its support plate will slide smoothly along the roller 13, thereby improving the convenience of moving the seedling tray 4. Through the introduction of the roller 13, the seedling tray 4 can be taken and placed very conveniently, which greatly improves the operating efficiency.

[0026] In a further preferred embodiment of the present invention, a fixed plate 14 is fixedly installed in the water tank 1, and the fixed plate 14 separates the water tank 1 into a water storage chamber, a mixing chamber and a liquid storage chamber. A three-way valve 15 is installed on the water inlet end of the water pump 8, and the two connecting ends of the three-way valve 15 are respectively connected to the water storage chamber and the mixing chamber.

[0027] In this embodiment, when it is necessary to carry out conventional irrigation on the rice, the three-way valve 15 is operated to connect the water inlet end of the water pump 8 with the water storage chamber, and the clean water is extracted and evenly sprayed to each layer of the seedling tray 4 through the irrigation system; and when it is necessary to spray nutrients on the rice, the three-way valve 15 is operated to switch to the mixing chamber, at which time the water pump 8 draws the mixed nutrient solution in the mixing chamber into the mixing chamber and sprays it evenly on the rice through the drainage pipe 5.

[0028] In a further preferred embodiment of the present invention, a threaded rod 16 is rotatably installed in the liquid storage chamber, and a push plate 17 is threadedly sleeved on the threaded rod 16, and the push plate 17 is in sliding contact with the inner wall of the liquid storage chamber. A connecting pipe 18 is fixedly installed on one side of the water tank 1, and the two ends of the connecting pipe 18 are respectively connected to the liquid storage chamber and the mixing chamber, and a water pump 19 is fixedly installed at the bottom of the water storage chamber, and the discharge end of the water pump 19 is connected to the mixing chamber.

[0029] In this embodiment, when it is necessary to add nutrients to the mixing chamber, water pump 19 is first started. Water pump 19 extracts a certain amount of water from the water storage chamber and discharges it into the mixing chamber to provide a basic liquid for mixing the nutrients. Subsequently, the threaded rod 16 is driven to rotate. The rotation of the threaded rod 16 drives the push plate 17 to slide along the threaded direction in the liquid storage chamber. As the push plate 17 slides, the nutrients in the liquid storage chamber are gradually squeezed and pushed into the mixing chamber through the connecting tube 18, and mixed with the water previously pumped in by water pump 19 to complete the mixing operation.

[0030] In a further preferred embodiment of the present invention, the mixing mechanism includes: a stirring rod 20 rotatably installed in a mixing chamber for mixing water and nutrients; a fixed rod 21 rotatably installed on the top of the mixing chamber; a differential wheel 22 fixedly mounted on one end of the fixed rod 21 and the threaded rod 16, respectively, and the two differential wheels 22 are meshed with each other; a bevel gear 23 fixedly mounted on the other end of the stirring rod 20 and the fixed rod 21, and the two bevel gears 23 are meshed with each other; and a driving mechanism provided on the water tank 1 and the box body 2 for driving the stirring rod 20 to rotate.

[0031] In this embodiment, when the push plate 17 slides along the liquid storage chamber driven by the threaded rod 16 and pushes the nutrient agent to the mixing chamber, the rotation of the threaded rod 16 not only drives the movement of the push plate 17, but also drives the rotation of the fixed rod 21 through the meshing action of the differential wheel 22. Since the other ends of the fixed rod 21 and the stirring rod 20 are respectively fixedly sleeved with meshing bevel gears 23, the rotation of the fixed rod 21 will further drive the stirring rod 20 to rotate in the mixing chamber. The rotation of the stirring rod 20 generates a strong stirring force, so that the nutrient agent and water entering the mixing chamber can be quickly and evenly mixed together, which is convenient for subsequent watering operations.

[0032] In a further preferred embodiment of the present invention, the driving mechanism includes: a connecting box 24 fixedly mounted on the top of the box body 2; a rotating rod 25 rotatably mounted on one side of the box body 2, and the rotating rod 25 is rotatably connected to the connecting box 24; a round rod 30 rotatably mounted in the connecting box 24; a sprocket 26 fixedly mounted on the round rod 30 and the rotating rod 25 respectively; a chain 27 mounted on a group of the sprockets 26; a motor 28 fixedly mounted on the top of the inner wall of the connecting box 24 for driving the round rod 30 to rotate; a bevel gear 29 fixedly mounted on the output shaft of the motor 28 and the round rod 30 respectively; and a connecting mechanism provided on the rotating rod 25 and the threaded rod 16.

[0033] In this embodiment, when it is necessary to drive the threaded rod 16 to rotate, the motor 28 is started first, and the output shaft of the motor 28 drives the bevel gear 29 fixedly mounted thereon to rotate. Since the bevel gear 29 is meshed with the bevel gear 29 fixedly mounted on the round rod 30, the round rod 30 will also rotate therewith. The rotation of the round rod 30 further drives the rotation of the sprocket 1 26 fixedly mounted thereon. The sprocket 1 26 is connected to another sprocket 1 26 fixedly mounted on the rotating rod 25 through a chain 1 27 mounted thereon. Therefore, the rotating rod 25 will also rotate with the rotation of the round rod 30. The rotation of the rotating rod 25 is finally transmitted to the threaded rod 16 through the connecting mechanism, causing the threaded rod 16 to start rotating. The rotation of the threaded rod 16 drives the push plate 17 to slide in the liquid storage chamber, thereby realizing the quantitative addition and pushing of the nutrient.

[0034] In a further preferred embodiment of the present invention, the connecting mechanism includes: a connecting frame 31 fixedly mounted on the bottom of the water tank 1; a group of sprocket wheels 32 respectively arranged on one side of the connecting frame 31 and one end of the threaded rod 16; a chain 33 sleeved on a group of sprocket wheels 32; a connecting telescopic rod 34 rotatably arranged on the top of the connecting frame 31, a group of circular plates 35 respectively fixedly mounted on the connecting telescopic rod 34 and one end of the rotating rod 25, and a group of the circular plates 35 are arranged relatively to each other; a group of bevel gears 36 respectively fixedly mounted on the connecting telescopic rod 34 and the output rod of the sprocket wheel 32 located on the connecting frame 31, and a group of the bevel gears 36 are meshed with each other; an electric telescopic rod 37 fixedly mounted on the top of the connecting frame 31, a limit block is installed on the electric telescopic rod 37, and the limit block is rotatably sleeved on the connecting telescopic rod 34.

[0035] In this embodiment, before starting the motor 28, the electric telescopic rod 1 37 is started first. The telescopic movement of the electric telescopic rod 1 37 drives the telescopic connection rod 34 fixedly connected thereto to extend and retract. The telescopic connection rod 34 further makes the two circular plates 35 fit closely together, and this fit ensures the stability and reliability of subsequent power transmission; then, the motor 28 is started, and the output shaft of the motor 28 drives the rotating rod 25 to rotate and rotates together with the telescopic connection rod 34; the telescopic connection rod 34 synchronously drives the bevel gear 3 36 to rotate, and at the same time, the sprocket 2 32 will also rotate with the rotation of the telescopic connection rod 34, and the rotation of the sprocket 2 32 is transmitted to another sprocket 2 32 through the chain 2 33, and the sprocket 2 32 is connected to one end of the threaded rod 16. Therefore, the threaded rod 16 will also rotate with the rotation of the sprocket 2 32, and the rotation of the threaded rod 16 ultimately drives the push plate 17 to slide in the liquid storage chamber, thereby realizing the quantitative addition and pushing of the nutrient agent.

[0036] In a further preferred embodiment of the present invention, the partition 3 is arranged in an arc shape, a connecting pipe 38 is fixedly installed on one side of the box body 2, a branch pipe of the connecting pipe 38 is fixedly connected to the box body 2, and the branch pipe is communicated with the seedling chamber, and a collecting box 39 is threadedly installed on the bottom end of the connecting pipe 38.

[0037] In this embodiment, when watering is performed, excess liquid such as water and nutrient solution that are not absorbed by the soil or sprayed outside the seedling tray 4 will flow along this slope. Due to the arc design of the partition 3, these excess liquids will be guided to the entrance of the connecting tube 38. When the excess liquid enters the connecting tube 38, they will be collected in the collecting box 39. The design of the collecting box 39 allows the user to easily remove and clean the liquid therein, thereby keeping the interior of the box 2 clean and tidy.

[0038] In a further preferred embodiment of the present invention, an electric rolling door assembly 40 is installed on one side of the box body 2, one side of the box body 2 is arranged in an open shape, and a guide rail for guiding the rolling door is installed at the opening of the box body 2, a plurality of ventilation holes for ventilating the seedling chamber are opened on the box body 2, and a controller 41 for operating the electric rolling door assembly 40 and the motor 28 is fixedly installed on the base.

[0039] In this embodiment, the design of the electric rolling door assembly 40 allows the user to conveniently control the closing and opening states of the box opening of the box body 2. At the same time, a plurality of ventilation holes are provided on the box body 2, which are used to improve the ventilation conditions of the seedling chamber, ensure that the rice can obtain sufficient air circulation during the growth process, reduce the occurrence of diseases and pests, and promote the healthy growth of rice; the controller 41 can receive user instructions and control the opening and closing of the electric rolling door assembly 40, as well as the starting and stopping of the motor 28, thereby realizing comprehensive intelligent management of the rice planting box.

[0040] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments: In another embodiment of the present invention, the box body 2 is provided with a feeding mechanism for automatically loading and unloading the seedling tray 4, and the feeding mechanism includes: a one-way screw 42 rotatably installed on both sides of the box body 2; a slider 43 threadedly sleeved on the two one-way screws 42, one side of the two sliders 43 is in sliding contact with one side of the box body 2; a T-shaped plate 44 fixedly installed on one side of the slider 43; a placement box 45 slidably arranged on the T-shaped plate 44 for loading and unloading the seedling tray 4; a sprocket three 69 fixedly sleeved on the two one-way screws 42; a chain three 70 sleeved on the two sprocket three 69, and the chain three 70 passes through the box body 2; a connecting mechanism provided on the one-way screw 42 and the round rod 30 for driving the one-way screw 42 to rotate.

[0041] In the present embodiment, when it is necessary to unload the seedling tray 4, the electric rolling shutter door assembly 40 is first started to fully expose the opening of the box body 2, and then the one-way screw 42 is driven to rotate by the connecting mechanism to make the placement box 45 slide up and be at the same horizontal position as the seedling tray 4 to be unloaded, so as to facilitate the subsequent movement and placement operations; at this time, the seedling tray 4 is moved from the storage position to the placement box 45 by the moving mechanism, and after the placement of the seedling tray 4 is completed, the one-way screw 42 is driven to rotate again by the connecting mechanism to make the placement box 45 slide along one side of the box body 2 The seedling tray 4 is then removed from the placing box 45 and the placing box 45 is then removed and stored, thereby reducing floor space.

[0042] In another embodiment of the present invention, a moving mechanism for moving the seedling tray 4 is provided in the seedling raising chamber, and the moving mechanism includes: a one-way screw 48 rotatably installed in the seedling raising chamber; a threaded barrel 49 threadedly sleeved on the one-way screw 48; an L-shaped plate 50 fixedly installed on the top of the threaded barrel 49; a connecting block 51 fixedly installed on one side of the seedling raising tray 4; an electric telescopic rod 52 installed on one side of the L-shaped plate 50, a clamping block 53 is installed on the electric telescopic rod 52, and the clamping block 53 is adapted to the slot of the connecting block 51; a connecting switch 54 for controlling the opening and closing of the electric telescopic rod 52 is installed on one side of the L-shaped plate 50.

[0043] In this embodiment, when the seedling tray 4 needs to be unloaded, the one-way screw rod 48 is first driven to rotate by the motor 28. Since the one-way screw rod 48 and the threaded barrel 49 are threadedly sleeved, when the one-way screw rod 48 rotates, the threaded barrel 49 moves along the axial direction of the one-way screw rod 48. The movement of the threaded barrel 49 drives the L-shaped plate 50 fixedly installed on the top thereof to move synchronously. At this time, the electric telescopic rod 52 on the L-shaped plate 50 clamps the connecting block 51 on one side of the seedling tray 4 through the clamping block 53. , thereby achieving the clamping and movement of the seedling tray 4. While the seedling tray 4 is moving, the connection switch 54 will receive the command from the controller 41. After a preset time, such as 5-8 seconds, the connection switch 54 will control the electric telescopic rod 2 52 to open, so that the clamping block 53 is away from the connecting block 51, thereby releasing the seedling tray 4. At this time, the seedling tray 4 has slid into the placement box 45, and then the threaded cylinder 49 and the L-shaped plate 50 are reset to the initial position.

[0045] In this embodiment, when the L-shaped plate 50 moves, the sliding cooperation between the guide rod 55 and the guide block 56 can ensure that the clamping block 53 moves smoothly along a preset track, thereby preventing the clamping block 53 from deflecting or shaking during the movement.

[0046] In another embodiment of the present invention, a group of mounting blocks 57 are fixedly installed on one side of the box body 2, and bevel gears 459 are provided on any of the mounting blocks 57 and the one-way screw 248, and the two bevel gears 459 are meshed with each other, and a guide telescopic rod 58 is rotatably installed on the other mounting block 57, and the output rod of the guide telescopic rod 58 and the rotating rod 25 are fixedly sleeved with bevel gears 565, and the guide telescopic rod 58 and the output rod of the bevel gear 459 located on the mounting block 57 are fixedly installed with round Disc 160, the two discs 160 are in close contact, one side of any mounting block 157 is fixedly mounted with an electric telescopic rod 3 61 for driving the guide telescopic rod 158 to extend and retract, a fixing frame 162 is mounted on the electric telescopic rod 3 61, and the fixing frame 162 is rotatably connected to the guide telescopic rod 158, one side of the fixing frame 162 is fixedly mounted with an annular plate 163, an output rod of the guide telescopic rod 158 is mounted with a connecting plate 164, and the connecting plate 164 is arranged opposite to the annular plate 163.

[0047] In this embodiment, when any seedling tray 4 is unloaded, the electric telescopic rod three 61 matched therewith will be started, so that the two discs 1 60 are closely fitted, and then the motor 28 is started to drive the rotating rod 25 to rotate, and the rotating rod 25 simultaneously drives the bevel gear five 65 to rotate. When one of the bevel gears five 65 rotates, the other bevel gear five 65 and the guide telescopic rod 1 58 connected thereto can be driven to rotate synchronously. The output rod of the guide telescopic rod 1 58 is arranged in a rectangular shape, and the disc 1 60 at one end of the guide telescopic rod 1 58 is closely fitted with the disc 1 60 on the bevel gear four 59 to ensure the transmission effect therebetween. Then, the rotation of the guide telescopic rod 1 58 is transmitted to the bevel gear four 59, thereby driving the one-way screw two 48 to rotate, thereby realizing the automatic movement and positioning of the seedling tray 4.

[0048] In another embodiment of the present invention, the connection mechanism includes: a fixed block fixedly installed in the connection box 24; a connection component 71 rotatably installed in the connection box 24; a bevel gear six 72 respectively provided on the one-way screw 42 and the fixed block, and the two bevel gears six 72 are meshed with each other; a sprocket four 73 respectively fixedly mounted on the connection component 71 and the output rod of the bevel gear six 72 located on the fixed block, and a chain four 74 is mounted on the two sprockets four 73; a bevel gear seven 75 respectively fixedly mounted on the connection component 71 and the round rod 30, and the two bevel gears seven 75 are meshed with each other.

[0049] When the round rod 30 is driven by the motor 28 to rotate, the connecting assembly 71 can be driven to rotate synchronously through the transmission effect of the bevel gear 75; when the placement box 45 is driven to slide up and down, the motor 28 is first started so that the output shaft of the motor 28 drives the round rod 30 to rotate. The rotation of the round rod 30 drives the connecting assembly 71 to rotate through the transmission effect of the bevel gear 75. The rotation of the connecting assembly 71 drives the one-way screw 42 to rotate through the transmission chain of the sprocket four 73, the chain four 74 and the bevel gear six 72. The rotation of the one-way screw 42 drives a group of sliders 43 connected thereto to rotate synchronously through the chain three 70 and the sprocket three 69, thereby achieving the purpose of a group of sliders 43 sliding up and down synchronously.

[0050] In another embodiment of the present invention, the connecting assembly 71 is composed of two connecting rods, two mounting blocks 76, a guide telescopic rod 77, two discs 78, an electric telescopic rod 79, a fixing frame 80, a ring plate 81 and a connecting plate 82. The two mounting blocks 76 are fixedly installed in the connecting box 24, and the two connecting rods are rotatably installed on the two mounting blocks 76, respectively. The guide telescopic rod 77 is installed on any of the connecting rods, and the two discs 78 are fixedly installed on the other connecting rod. The connecting rod is on the guide telescopic rod 2 77, and the two discs 2 78 are in close contact. The electric telescopic rod 4 79 is fixedly mounted on any one of the mounting blocks 2 76. The fixing frame 2 80 is fixedly mounted on the electric telescopic rod 4 79, and the fixing frame 2 80 is rotatably sleeved on the guide telescopic rod 2 77. The annular plate 2 81 is fixedly mounted on one side of the fixing frame 2 80. The connecting plate 2 82 is fixedly mounted on the guide telescopic rod 2 77, and the connecting plate 2 82 is arranged opposite to the annular plate 2 81.

[0051] In this embodiment, when it is necessary to drive the seedling tray 4 to move into the placement box 45, if the placement box 45 is fixed at a certain height, the state of the connecting assembly 71 is adjusted by controlling the extension and retraction of the electric telescopic rod 4 79. Specifically, the electric telescopic rod 4 79 drives the fixed frame 2 80 to move, thereby contracting the guide telescopic rod 2 77. At the same time, the guide telescopic rod 2 77 drives one of the discs 2 78 to move, so that a group of discs 2 78 are separated from each other. At this time, since the two discs 2 78 are separated, the connecting rod that cooperates with the one-way screw 1 42 is called a stationary connecting rod. Keeping still, the other connecting rod, called the rotating connecting rod, still rotates with the rotation of the output shaft of the motor 28; at the same time, the annular plate 2 81 is close to the connecting plate 2 82, further ensuring that the one-way screw 1 42 will not rotate due to misoperation, thereby fixing the placement box 45 at a certain height while safely and stably driving the seedling tray 4 to move into the placement box 45. Through the coordinated use of the electric telescopic rod 4 79, the guide telescopic rod 2 77 and the disc 2 78, the state of the connecting assembly 71 can be accurately controlled, thereby achieving accurate control of the movement process of the seedling tray 4.

[0052] In another embodiment of the present invention, a connecting cover 66 is fixedly installed on one side of the box body 2, a connecting port is opened on one side of the box body 2, an electric push rod 68 is fixedly installed on the top of the inner wall of the connecting cover 66, a bracket 67 is installed on the output rod of the electric push rod 68, the bracket 67 is fixedly connected to one side of the support frame 9, and the support rod of the support frame 9 passes through the connecting port.

[0053] In this embodiment, when the seedling tray 4 needs to be taken out, the electric push rod 68 is started to retract its output rod, thereby driving the bracket 67 and the support frame 9 connected thereto to slide up together. Since the support rod of the support frame 9 passes through the connecting port, when the support frame 9 slides up, it will move away from the seedling tray 4, providing sufficient space for taking out the seedling tray 4.

[0054] In another embodiment of the present invention, a loosening frame 83 is placed in the planting groove of the seedling tray 4, and an elastic metal sheet 84 is fixedly installed on the top of the loosening frame 83. Blocks 85 are fixedly installed on the elastic metal sheet 84 and the support frame 9, and the two blocks 85 are clamped together. A limiting rod 86 for limiting the sliding distance of the loosening frame 83 is fixedly installed in the planting groove, and the limiting rod 86 passes through the loosening frame 83.

[0055] In this embodiment, when it is necessary to take out the rice, the electric push rod 68 is first started to make the support frame 9 drive the block 85 to slide up, and at the same time, the block 85 drives the loosening frame 83 to slide up synchronously. Since the loosening frame 83 is placed at the bottom of the planting trough and the bottom plate of the loosening frame 83 is provided with multiple openings, its sliding will directly push the planting soil upward from the bottom of the planting soil, so that the planting soil is separated from the inner wall of the planting trough, thereby facilitating the subsequent removal of the rice; when the loosening frame 83 slides up, it slides along the limit rod 86, so that the limit rod 86 limits the loosening frame 83. When the loosening frame 83 reaches a predetermined sliding height, the block 85 located on the support frame 9 will continue to apply pressure to the block 85 on the loosening frame 83. Since the elastic metal sheet 84 has a certain elasticity, it will deform so that the two blocks 85 can separate from each other. In this way, the loosening frame 83 is left in the planting trough, and the support frame 9 can continue to slide up, providing more space for taking out the seedling tray 4.

[0056] In another embodiment of the present invention, a one-way screw rod 3 87 is rotatably installed on the top of the seedling raising chamber, and a scraper 88 for cleaning water drops on the fill light 10 is threadedly sleeved on the one-way screw rod 3 87, a rack 89 is fixedly installed on one side of the support frame 9, and a driven gear 90 is rotatably installed in the seedling raising chamber, and the driven gear 90 is meshed with the rack 89, and a mounting frame 91 is fixedly installed on one side of the seedling raising chamber, and a differential wheel 2 92 is provided on the output rod of the mounting frame 91 and the driven gear 90, and the two differential wheels 2 92 are meshed with each other, and a connecting rod is rotatably installed on the mounting frame 91, and a bevel gear 8 93 is fixedly installed on the bottom end of the connecting rod and the differential wheel 2 92 located on the mounting frame 91, and the two bevel gears 8 93 are meshed with each other, and a differential wheel 3 94 is sleeved on the top of the connecting rod and the one-way screw rod 3 87, and the two differential wheels 3 94 are meshed with each other.

[0057] In this embodiment, when the support frame 9 slides up, the rack 89 synchronously drives the driven gear 90 to rotate. At this time, the two differential wheels 2 92 rotate, and then the rotational power is transmitted to the one-way screw 3 87 through the bevel gear 8 93 and the differential wheel 3 94 on the connecting rod, so that the scraper 88 slides to one side to clean the water droplets on the fill light 10.

[0058] In another embodiment of the present invention, a plurality of control switches 46 are fixedly installed on one side of the box body 2, and the plurality of control switches 46 are used to control the opening and closing of the electric telescopic rod 479. A touch rod 47 is fixedly installed on one side of the slider 43, and the touch rod 47 is adapted to the plurality of control switches 46.

[0059] In this embodiment, when it is necessary to unload the seedling tray 4 of a certain layer, firstly, the corresponding number of layers is selected by operating the controller 41, so that the control switch 46 of the corresponding layer is powered on, while the control switches 46 of other layers are not powered on. Then, the slider 43 drives the touch rod 47 to slide up. When the touch rod 47 slides up and contacts the control switch 46 of the corresponding layer, the control switch 46 is triggered, thereby turning off the motor 28 connected to the electric telescopic rod four 79. Next, the control system will control the electric telescopic rod four 79 to move, so that the two discs 278 are separated from each other, so that the placement box 45 is fixed at a certain height, which is convenient for the subsequent unloading operation of the seedling tray 4.
