[0009] Preferably, a float capable of floating up due to the buoyancy of water is slidably connected in the water tank, the float is arranged on one side of the clamping rod and can drive the clamping rod to move toward the clamping slot, and the buoyancy of the float is greater than the elastic force of the third spring.

[0010] Preferably, the water tank is provided with a water outlet, the tank body is rotatably connected with a top shaft, the top shaft is fixedly sleeved with an impeller, and the impeller is arranged below the water outlet.

[0011] Preferably, the box body is slidably connected to a window panel that can block the vent, and the box body is slidably connected to a latch that can limit the window panel, and the latch is connected to the box body via a fourth spring.

[0012] Preferably, the box body is slidably connected to a rack that can drive the latch to release the limit on the window panel, and the box body is rotatably connected to a gear ring, and the gear ring is meshed with the rack.

[0013] Preferably, the top shaft fixing sleeve is provided with a rotating wheel, the rotating wheel is rotatably connected with a clamping claw, the clamping claw is connected to the rotating wheel through a tension spring, the rotating wheel is arranged on the inner side of the gear ring, and the inner side of the gear ring is provided with a small clamping groove for the clamping claw to be clamped into.

[0014] Preferably, the water outlet is slidably connected to a sealing plate, the sealing plate is connected to the water outlet via a first spring, the sealing plate is provided with a water hole, and the water outlet is slidably connected to a blocking plate capable of blocking the water hole.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present application is provided with a water tank, which can collect rainwater. As the rainfall increases, the water tank drops, which can drive the cylindrical cam to rotate. The cylindrical cam can drive the rotating shaft to rotate under the action of the one-way bearing, and the rotating shaft drives the coil spring to store force. When the cylindrical cam stops rotating, the coil spring can drive the scraper to clean the filter through the one-way bearing.

The slide rod will slide into the extension slot, and the top shaft can lift the sealing plate upward to increase the water outlet speed. If the water flow speed is too fast, when it reaches the threshold, the claw will be stuck in the small slot to drive the gear ring to rotate. At this time, the window panel can be reset and the vent can be closed, thereby protecting the fruit tree seedlings.

[0020] 3. The present application is provided with a float. When there is water in the water tank, the float will drive the card rod to slide into the card slot. Therefore, as long as the water in the water tank has not completely flowed out, the water tank will not reset at this time, allowing the water in the water tank to have enough time to flow out, thereby facilitating the water discharge work. When the water flows away, the float resets, and the water tank can be reset under the elastic force of the spring. The set water tank can realize buffering of rainwater collection and prevent excessive water inflow at one time, thereby reasonably controlling the amount of rainwater collected.

DETAILED DESCRIPTION

[0036] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] like Figure 1-Figure 12As shown, this embodiment proposes a fruit tree seedling raising device with rainwater collection and utilization function, including a box body 1, the box body 1 is rotatably connected to a solar panel 6, the box body 1 is fixedly connected to an electric push rod 61, the electric push rod 61 is hinged with a connecting rod, and the other end of the connecting rod is connected to the solar panel 6. When the electric push rod 61 is working, it can drive the solar panel 6 to rotate, thereby realizing the storage and deployment of the solar panel 6, and the solar panel 6 is used for the energy supply work of the box body 1 as a whole.

[0038] The box body 1 is provided with a water collecting trough 2, which is arranged on one side of the solar panel 6. The box body 1 can be connected to a rain sensor, and the rain sensor and the electric push rod 61 are connected to a controller. When rain is detected, the electric push rod 61 can drive the solar panel 6 to rotate around the box body 1. At this time, the solar panel 6 plays a role of diversion, and rainwater can be diverted into the water collecting trough 2 for collection.

[0039] A water tank 34 for collecting rainwater is slidably connected in the water collecting trough 2. A storage box for storing rainwater is provided at the bottom of the box body 1. The water collecting trough 2 is connected to the storage box through a water pipe 12. The storage box is connected to a water pump 11. The water pump 11 can transport the water in the storage box to the irrigation system, and the irrigation system can irrigate the fruit tree seedlings in the box body 1.

[0040] The water tank 34 is connected to the box body 1 through a second spring 38. The box body 1 is rotatably connected to a cylindrical cam 36. The cylindrical cam 36 is provided with a slide groove. The water tank 34 is connected to a slide rod 37. The slide rod 37 is slidably set in the slide groove. The box body 1 is detachably connected to a filter screen 3. The filter screen 3 is set above the water tank 34 and also includes a rotatable scraper 32 for cleaning the filter screen 3. The cylindrical cam 36 can drive the scraper 32 to rotate.

[0041] A collecting box 4 is arranged on one side of the scraper 34, and one end of the filter screen 3 is an inclined surface, and is inclined toward the collecting box 4. The scraper 34 can hang the garbage into the inclined surface, and then the garbage can slide into the collecting box 4. The bottom end and side wall of the collecting box 4 are provided with a plurality of through holes, and the water in the collecting box 4 can flow into the sump 2, while the garbage is left in the collecting box 4.

[0042] It also includes a rotating shaft 39 that slides through the water tank 34, and a second spring 38 is sleeved on the rotating shaft 39. The upper end of the second spring 38 is connected to the water tank 34, and the lower end of the second spring 38 is connected to the box body 1. Under the elastic force of the second spring 38, in the initial state, the water tank 34 is located above the box body 1. When rainwater enters, the water tank 34 drops, compressing the second spring 38.

[0043] The slide bar 37 is a retractable spring bar, and the bottom surface of the slide groove is ratchet-shaped. Through this arrangement, the slide bar 37 can only slide in one direction in the slide groove. When the water tank 34 drives the slide bar 34 to descend, it can drive the cylindrical cam 36 to rotate and drive the scraper 32 to make a circular motion, thereby realizing the cleaning of the filter screen 3.

[0044] The water tank 34 is slidably connected to a clamping rod 45 that moves horizontally. The clamping rod 45 is connected to the water tank 34 through a third spring. The box body 1 is provided with a clamping groove 13 for the clamping rod 45 to slide into. The third spring is sleeved on the clamping rod 45. One end of the third spring is connected to the clamping rod 45, and the other end is connected to the water tank 34. In the initial state, the clamping rod 45 is on one side of the clamping groove 13 under the elastic force of the third spring.

[0045] A float 46 is slidably connected in the water tank 34 and can float up due to the buoyancy of water. The float 46 is arranged on one side of the card rod 45 and can drive the card rod 45 to move toward the direction close to the card slot 13. The buoyancy of the float 46 is greater than the elastic force of the third spring, so the float 46 can push the card rod 45 to slide into the card slot 13, causing the third spring to deform. When the float 46 is reset, the third spring can drive the card rod 45 to slide out of the card slot 13.

[0046] The side surface of the float 46 is an inclined surface, so when the float 46 rises, it can drive the clamping rod 45 to move, and the clamping rod 45 can slide into the clamping groove 13. At this time, the water tank 13 cannot move upward, and the water tank 13 will not reset. The water in the water tank 13 has enough time to flow away, thereby facilitating the water discharge work. When the water flows away, the float 46 resets, and the water tank 13 can be reset under the elastic force of the second spring 37.

[0047] The water tank 34 is provided with a water outlet, the box body 1 is rotatably connected with a top shaft 23, the top shaft 23 is fixedly sleeved with an impeller 22, and the impeller 22 is arranged below the water outlet. The water flowing out of the water outlet flows into the water collecting tank 2, and the water in the water collecting tank 2 can flow into the storage tank through the water pipe 12.

[0048] The box body 1 is slidably connected to a window panel 42 for blocking the vent, and the window panel 42 slides in the vertical direction. The box body 1 is slidably connected to a latch 41 for limiting the window panel 42. The latch 41 is connected to the box body 1 through a fourth spring, and the window panel 42 has a limiting hole. In the initial state, under the elastic force of the fourth spring, the latch 41 slides into the limiting hole. At this time, the window panel 42 cannot descend. When the latch 41 slides out of the limiting hole, under the action of gravity, the window panel 42 descends, so that the vent can be closed.

[0049] The box body 1 is slidably connected to a rack 51 which can drive the latch 41 to release the limit on the window panel 42. The box body 1 is rotatably connected to a ring gear 52 which meshes with the rack 51. A magnet 44 which attracts the latch 41 is connected to the left side of the rack 51. When the rack 51 moves to the left, it can directly drive the latch 41 on the right to slide out of the limit hole. The magnet 44 moves to the side of the latch 41 on the left, so that the latch 41 on the left can be moved out of the limit hole.

[0050] The top shaft 23 is fixedly sleeved with a rotating wheel 53, and the rotating wheel 53 is rotatably connected with a claw 54, and the claw 54 is connected to the rotating wheel 53 through a tension spring 55. The rotating wheel 53 is arranged on the inner side of the ring gear 52, and a small groove for the claw 54 to be inserted into is opened on the inner side of the ring gear 52. One end of the tension spring 55 is connected to the claw 54, and the other end of the tension spring 55 is connected to the rotating wheel 53. The elastic force of the tension spring 55 is suitable enough. In the initial state, under the elastic force of the tension spring 55, the claw 54 will not slide into the small groove.

[0051] If the water flow speed is too fast, when it reaches the threshold, the rotation speed of the wheel 53 is fast enough, and the claw 54 is locked in the small slot to drive the ring gear 52 to rotate, and the ring gear 52 can drive the rack 51 to slide. At this time, the pin 41 can be moved out of the limit hole. Under the action of gravity, the window panel 42 is reset to close the vent, thereby protecting the fruit tree seedlings.

[0052] The water outlet is slidably connected with a sealing plate 24, which is connected to the water outlet through a first spring 21. The upper end of the first spring 21 is connected to the water outlet, and the lower end of the first spring 21 is connected to the sealing plate 24. Under the elastic force of the first spring 21, the sealing plate 24 contacts the bottom end of the water outlet, and the first spring 21 is in a compressed state.

[0053] The sealing plate 24 is provided with a water hole, and the water outlet is slidably connected with a plugging plate 25 that can block the water hole. In the initial state, under the action of gravity, the plugging plate 25 and the sealing plate 24 are in contact, and the plugging plate 25 blocks the water hole, so that no water can be discharged, and the water tank 34 can collect water. Only when the top shaft 23 pushes the plugging plate 25 upward, the water hole will be opened, and the water tank 34 will discharge water through the water hole. The water tank 34 can realize the buffering of rainwater collection, prevent too much water from entering at one time, and thus reasonably control the amount of rainwater collected.

[0054] The chute includes an inclined chute and a vertical chute. The upper and lower ends of the vertical chute are respectively connected to the inclined chute. The two ends of the inclined chute are respectively connected to the lower end and the upper end of the vertical chute on both sides. The lower end of the vertical chute also extends downward with an extension chute. When the slide rod 37 slides from the inclined chute into the vertical chute, the position of the water tank 34 is satisfied, and the top shaft 23 just lifts the blocking plate 25, and water flows out of the water hole.

[0055] As the amount of rainfall increases, when it rains heavily, the water outflow speed is much lower than the water inflow speed, the slide bar 37 will slide into the extension groove, and the top shaft 23 can push up the sealing plate 24 to increase the water outflow speed. At the same time, when the rainfall increases further and the impeller 22 rotates too fast, the window plate 42 can be reset to close the vent.

[0056] The cylindrical cam 36 is connected to the rotating shaft 39 through the second one-way bearing 35. The rotating shaft 39 is connected to the scraper 32 through the first one-way bearing 31. The rotating shaft 39 is connected to the filter 3 through the coil spring 33. The limiting directions of the second one-way bearing 35 and the first one-way bearing 31 are opposite.

[0057] A one-way bearing is a bearing that can rotate freely in one direction but is locked in the other direction. When the slide rod 37 descends to drive the cylindrical cam 36 to rotate, the second one-way bearing 35 is in a locked state, which can drive the rotating shaft 39 to rotate, thereby storing force of the coil spring 33. The first one-way bearing 31 is in an unrestricted state, and the rotating shaft 39 rotates relative to the scraper 32.

[0058] By adopting the method of storing force by the coil spring 33, when encountering garbage that cannot be cleaned up, since the coil spring 33 itself is flexible, it will not cause damage to the device, and will not get stuck, which can facilitate the cleaning work and improve the overall reliability of the device.

[0059] A method for using a fruit tree seedling raising device with a rainwater collection and utilization function, using the above-mentioned fruit tree seedling raising device with a rainwater collection and utilization function, comprising the following steps:

[0060] S1: When it rains, rainwater enters the water tank 34 after being filtered by the filter 3. As the rainwater is collected, the water tank 34 descends, and the water tank 34 drives the cylindrical cam 36 to rotate through the slide bar 37. The cylindrical cam 36 drives the rotating shaft 39 to rotate through the second one-way bearing 35. The rotating shaft 39 drives the coil spring 33 to store force, and the rotating shaft 39 rotates relative to the scraper 32.

[0061] S2: As the water tank 34 descends, when the slide bar 37 slides into the vertical slot, the top shaft 23 lifts up the blocking plate 25, and water flows out through the water hole. The water flows through the impeller 22 to drive the top shaft 23 to rotate. At this time, the claw 54 will not slide into the small slot, and the rotating wheel 53 will not drive the gear ring 52 to rotate. The coil spring 33 drives the rotating shaft 39 to reverse, and the rotating shaft 39 drives the scraper 32 to rotate through the first one-way bearing 31, so as to clean the filter screen 3.

[0062] S3: With the increase of rainfall, when the water inlet speed is greater than the water outlet speed, the water tank 34 further descends, the slide rod 37 slides into the extension groove, the top shaft 23 pushes the sealing plate 24 upward, so that the water outlet speed increases, the water flow drives the rotating wheel 53 to speed up, the claw 54 slides into the small groove, the rotating wheel 53 drives the ring gear 52 to rotate, the ring gear 52 drives the rack 51 to move, the rack 51 drives the latch pin 41 to move, and the limit on the window panel 42 is released, and the window panel 42 closes the vent.

[0063] An intelligent control system is provided in the box 1. Through the built-in intelligent control system, key environmental parameters such as temperature, humidity and light can be monitored and adjusted to meet the needs of growth of different plants.

[0064] Adjustable lighting: Box 1 provides an adjustable lighting system that can simulate the lighting conditions required by plants at different growth stages.

[0065] Temperature and humidity control: The temperature and humidity control system built into the box 1 can accurately adjust the temperature and humidity in the box to provide the best environmental conditions required for plant growth.

[0067] Energy saving and environmental protection: The box 1 adopts energy-saving technology, which can minimize energy consumption and reduce the impact on the environment. The equipment in the box 1 can be powered by solar panels 6.

[0068] The device described in this application can also be used in agricultural planting, and can be used in farmland, greenhouse and other environments to help farmers improve the planting efficiency and quality of crops. Researchers can conduct plant growth experiments to study related issues and mechanisms of plant growth.

[0069] There are different functional areas in the box 1, including a sowing area, a seedling raising area and a grafting area to meet the needs of plants at different stages. This design makes seed cultivation and grafting more convenient and efficient.

[0070] Made of high-quality materials, it has good thermal insulation properties and can provide suitable temperature and humidity conditions to promote plant growth.

[0071] Equipped with a water and fertilizer management system, water and fertilizer can be easily supplied to maintain good root moisture and nutrient supply to ensure the healthy growth of plants. Through the rainwater collection system, filtered rainwater can be used for irrigation, or mixed with fertilizer for water and fertilizer fertilization.

[0072] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
