Description

Technical Field

[0001] This invention relates to the field of forest tree seedling technology, specifically to an intelligent sprinkler irrigation system for forest tree seedlings. Background Technology

[0002] Forest tree seedlings are an important foundation for the development of forestry. High-quality forest tree seedlings and a sufficient supply of seedlings are of great significance and importance to the sustainable development of forestry. Seedling cultivation means cultivating seedlings. Originally, it referred to cultivating seedlings in nurseries, hotbeds or greenhouses in preparation for transplanting to the ground. Currently, there are two methods of forest tree seedling cultivation: bed seedling cultivation and field seedling cultivation. Among them, bed seedling cultivation is the most widely used. It requires the use of planting trays or pots on the seedling bed for planting. After the seedlings are cultivated, they are transplanted to designated locations for planting.

[0003] During the seedling stage of forest trees, in order to ensure that the seedlings maintain good growth, it is necessary to water the seedlings in the seedbed regularly. The common methods are manual sprinkler irrigation and automatic sprinkler irrigation. Manual irrigation is prone to uneven watering among the seedlings. Therefore, most existing forest tree seedbeds are equipped with automatic sprinkler irrigation devices, which can spray water onto the seedlings regularly.

[0004] However, most existing automatic sprinkler irrigation devices consist of several sprinkler heads that are moved above the seedling bed. As they move above the seedling bed, they spray water onto the seedlings below. However, plants absorb water at their roots, and water needs to be poured into the soil around the roots. As the leaves of the seedlings grow, they tend to block some of the water, making it difficult for all the water to enter the soil and be absorbed by the seedling roots. Moreover, some seedlings cannot tolerate water in their leaves and leaf axils during growth (such as succulents, aloe vera, and Haworthia), otherwise it will lead to leaf axil rot and disease.

[0005] In addition, due to long-term spraying and watering of the soil in the planting trays or pots, the soil becomes compacted and hardened. Since the seedling roots grow inside the soil, the roots of the tree seedlings and the soil will stick to the inner wall of the planting trays or pots. When transplanting the tree seedlings later, they need to be pulled out manually, which can easily damage the seedlings and reduce their survival rate after transplanting. Summary of the Invention

[0006] In view of the above situation and to overcome the defects of the existing technology, the present invention provides an intelligent sprinkler irrigation device for forest seedling cultivation.

[0007] The technical solution adopted by this invention is as follows: an intelligent sprinkler irrigation device for forest seedling cultivation, including a seedling box. The top of the seedling box has several pot holes arranged in a rectangular array, and a seedling pot is fixedly installed in each pot hole. A spray displacement chute is opened at the rear end of the top surface of the seedling box. A spray water supply chute is opened on the top surface of the seedling box between every two rows of seedling pots. The rear ends of the multiple spray water supply chutes are connected to the spray displacement chute. A spray displacement slide seat with openings on the top and front side is slidably installed in the spray displacement chute. A spray water supply slide seat is installed in the spray displacement slide seat. The spray water supply slide seat can move into the spray water supply chute. A spray pipe is fixedly installed on the top of the spray water supply slide seat by a support rod. The left and right ends of the spray pipe are bent downward and spray heads are installed. An anti-sticking seedling emergence mechanism is installed in each seedling pot.

[0008] Preferably, the bottom surface of the spray displacement slide is flush with the bottom surface of the spray water supply groove. A spray return rack is installed on the bottom surface of the spray displacement slide, and a spray water supply rack is installed on the bottom surface of each spray water supply groove. When the spray displacement slide moves to the rear of one of the spray water supply grooves, a complete rack is formed between the spray return rack and the spray water supply rack. The bottom of the spray water supply slide is higher than the spray return rack and the spray water supply rack. A spray drive cavity is opened at the bottom of the spray water supply slide. A spray water supply worm gear is rotatably installed between the left and right sides of the spray drive cavity. The spray water supply worm gear can mesh and drive with the spray return rack and the complete rack formed between the spray water supply rack.

[0009] Preferably, a spray water supply worm gear meshing with a spray water supply worm wheel is rotatably mounted on the rear side of the spray drive chamber, and a spray water supply motor connected to the spray water supply worm gear is mounted on the rear side of the spray water supply slide. The left and right inner walls of the spray displacement slide and the left and right side walls of the multiple spray water supply slides are all provided with slide limit grooves, and the slide limit grooves between the spray displacement slide and the spray water supply slide are connected. The left and right sides of the spray water supply slide are all fixedly installed with slide limit blocks that slide in cooperation with the slide limit grooves. The spray water supply slide can move from inside the spray displacement slide to inside the spray water supply slide through the sliding cooperation between the slide limit grooves and the slide limit blocks.

[0010] Preferably, a displacement drive groove runs through the bottom of the spray displacement slide and the interior of the seedling box. A displacement drive screw located below the displacement drive groove is rotatably installed inside the seedling box. A displacement drive screw block that is threadedly connected to the displacement drive screw is fixedly installed at the bottom of the spray displacement slide. A displacement drive motor connected to the displacement drive screw is fixedly installed inside the seedling box.

[0011] Preferably, a displacement sensing switch is installed on the rear side of the spray displacement slide at a position behind each spray water supply slide, and a spray sensing switch is installed on the rear inner wall of the spray displacement slide and on the front side of each spray water supply slide.

[0012] Preferably, the anti-adhesion seedling emergence mechanism includes a seedling emergence top plate installed inside the seedling pot. A seedling emergence top tube that penetrates the bottom of the seedling pot is coaxially fixedly installed on the bottom surface of the seedling emergence top plate. A spring plate is installed on the outer side of the bottom end of the seedling emergence top tube. A seedling emergence top tube spring is sleeved on the outer side of the seedling emergence top tube. The two ends of the seedling emergence top tube spring abut against the bottom surface of the seedling pot and the top surface of the spring plate, respectively. A plurality of circumferentially evenly distributed scraper connecting rods are installed on the outer side of the seedling emergence top plate. An anti-adhesion scraper that abuts against the inner wall of the seedling pot is fixedly installed on the end of each scraper connecting rod away from the seedling emergence top plate.

[0013] Preferably, a seedling drive plate is slidably installed inside the seedling box. A plurality of seedling drive rods arranged in a rectangular array are fixedly installed on the top surface of the seedling drive plate. The top of each seedling drive rod is located inside the bottom end of a seedling tube. An anti-adhesion spiral groove is formed on the outer side of each seedling drive rod. An anti-adhesion rotating pin is fixedly installed on the inner wall of each seedling tube. The anti-adhesion rotating pin is located in the anti-adhesion spiral groove.

[0014] Preferably, the seedling box has seedling drive slots running through its left and right side walls, and seedling drive blocks extending from the seedling drive slots to the outside of the seedling box are fixedly installed on both sides of the seedling drive plate. Seedling drive cylinders are fixedly installed on both sides of the seedling box, and the output shaft of each seedling drive cylinder is fixedly connected to the seedling drive block on the same side.

[0015] Preferably, each of the seedling trays has a drainage hole at the bottom, and a number of mesh holes are passed through the upper and lower surfaces of the seedling drive plate. The seedling box is equipped with a water receiving tray located below the seedling drive plate.

[0016] The beneficial effects of this invention are as follows: 1. When the spray displacement slide moves to the rear end of one of the spray water supply slides, the spray water supply slide can move from inside the spray displacement slide to inside the spray water supply slide, and can move forward inside the spray water supply slide. During the movement, the spray heads at both ends of the spray pipe can spray water into the soil inside the seedling pots on both sides of the spray water supply slide, thereby achieving the purpose of watering only the soil without spraying water into the leaves or leaf center.

[0017] 2. When the spray water supply slide moves to the front end of the spray water supply trough, the water supply pump stops supplying water to the spray head. Then, the spray water supply slide moves to the rear end of the spray water supply trough and enters the interior of the spray displacement slide. Then, the spray displacement slide moves to the rear end of the next spray water supply trough, causing the spray water supply slide to move to the front end of the spray water supply trough to irrigate the soil in the seedling pots on both sides. This process continues until all the seedling pots have been irrigated.

[0018] 3. When seedlings need to emerge, to prevent the soil from sticking to the inner wall of the seedling pot, the seedling emergence tube can be rotated first. The seedling emergence tube will drive the seedling emergence plate and its multiple scraper rods on the outside to rotate. The multiple scraper rods will then drive multiple anti-sticking scrapers to rotate circumferentially against the inner wall of the seedling pot, thereby scraping away the soil sticking to the inner wall of the seedling pot. Then the seedling emergence tube can be moved upward, thereby lifting the soil upward through the seedling emergence plate. The staff can then remove the seedlings along with the soil around their roots and transplant them without damaging the seedlings.

[0019] 4. Drainage holes are provided at the bottom of the seedling trays to allow excess water to drain out, preventing seedling roots from rotting due to excessive water accumulation. Several mesh holes are connected between the top and bottom surfaces of the seedling drive plate. A water collection tray is located below the seedling drive plate inside the seedling box. Water flowing from the drainage holes onto the seedling drive plate and then through the mesh holes into the water collection tray below. Staff can periodically remove the water collection tray to clean the wastewater inside. Attached Figure Description

[0033] The following will refer to the appendix. Figures 1-12 The description provides a detailed description of various embodiments of the present invention.

[0034] Example 1: An intelligent sprinkler irrigation system for forest seedling cultivation, as shown in the attached diagram. Figures 1-12As shown, the device includes a seedling box 1. The top of the seedling box 1 has several rectangular arrayed pot holes, each containing a fixed seedling pot 2 for planting tree seedlings. A spray displacement chute 3 is located at the rear end of the top surface of the seedling box 1. A spray water supply chute 4 is located between every two rows of seedling pots 2 on the top surface of the seedling box 1. The rear ends of multiple spray water supply chute 4 are connected to the spray displacement chute 3. A spray displacement slide 5 with openings at the top and front side is slidably installed within the spray displacement chute 3. A spray water supply slide 6 is installed within the spray displacement slide 5. A spray nozzle is fixedly installed on the top of the spray water supply slide 6 via a support rod 7. The sprinkler pipe 8 is connected to a water supply pipe and a water pump. The left and right ends of the sprinkler pipe 8 are bent downwards and spray heads 9 are installed. The spray heads 9 are located above the top opening of the seedling pot 2 and face the soil inside the seedling pot 2. When the spray displacement slide 5 moves to the rear end of one of the spray water supply slides 4, the spray water supply slide 6 can move from the spray displacement slide 5 into the spray water supply slide 4 and can move forward inside the spray water supply slide 4. During the movement, the spray heads 9 at both ends of the sprinkler pipe 8 can spray water into the soil inside the seedling pot 2 on both sides of the spray water supply slide 4, thereby achieving the purpose of watering only the soil and not spraying water into the leaves or leaf center. When the spray water supply slide 6 moves to the front end of the spray water supply trough 4, the water supply pump stops supplying water to the spray head 9. Then, the spray water supply slide 6 moves to the rear end of the spray water supply trough 4 and enters the interior of the spray displacement slide 5. Then, the spray displacement slide 5 moves to the rear end of the next spray water supply trough 4, so that the spray water supply slide 6 moves to the front end of the spray water supply trough 4 to water the soil in the seedling pots 2 on both sides. This process continues until all the seedling pots 2 have been watered.

[0035] Each seedling pot 2 is equipped with an anti-adhesion seedling emergence mechanism 10. When seedlings need to emerge after the seedling stage, the anti-adhesion seedling emergence mechanism 10 can separate the soil from the inner wall of the seedling pot 2, and then push the soil and seedlings upwards. The staff can then directly remove the seedlings along with the soil, without the need for manual pulling out of the seedlings. This avoids damaging the seedlings during the pulling process and reducing the survival rate of the seedlings after transplanting.

[0036] Example 2, as shown in the appendix Figures 6-10As shown, the bottom surface inside the spray displacement slide 5 is flush with the bottom surface of the spray water supply slide 4. A spray return rack 11 is installed on the bottom surface inside the spray displacement slide 5. A spray water supply rack 12 is installed on the bottom surface of each spray water supply slide 4. When the spray displacement slide 5 moves to the rear of one of the spray water supply slides 4, a complete rack is formed between the spray return rack 11 and the spray water supply rack 12. The bottom of the spray water supply slide 6 is higher than the spray return rack 11 and the spray water supply rack 12. A spray drive cavity 13 is opened at the bottom of the spray water supply slide 6. A spray water supply worm gear 14 is rotatably installed between the left and right sides of the spray drive cavity 13. The spray water supply worm gear 14 can mesh and drive with the complete rack formed between the spray return rack 11 and the spray water supply rack 12. As attached Figure 8 , Figure 10 As shown, when the spray water supply slide 6 is inside the spray displacement slide 5, the spray water supply worm gear 14 and the spray return rack 11 are engaged. In use, the spray displacement slide 5 is moved to the rear of one of the spray water supply grooves 4, and then the spray water supply worm gear 14 is rotated. The spray water supply worm gear 14 and the spray return rack 11 engage, driving the spray water supply slide 6 into the spray water supply groove 4. When the spray water supply slide 6 reaches the inside of the spray water supply groove 4, the spray water supply worm gear 14 engages with the spray water supply rack 12, allowing the spray water supply slide 6 to move towards its front end within the spray water supply groove 4, thus irrigating the soil in the seedling pots 2 on both sides of the spray water supply groove 4. When the spray water supply slide 6 moves to the front end of the spray water supply trough 4, the spray water supply worm gear 14 rotates in the opposite direction, driving the spray water supply slide 6 to move towards the rear end of the spray water supply trough 4. When the spray water supply slide 6 enters the spray displacement slide 5, the spray water supply worm gear 14 separates from the spray water supply rack 12, and then engages with the spray return rack 11, so that the spray water supply slide 6 is fully inside the spray displacement slide 5. Then the spray displacement slide 5 can move to the rear end of the next spray water supply trough 4, and then the spray water supply slide 6 moves into the spray water supply trough 4 to spray and irrigate the seedling pot 2 on that side.

[0037] Example 3, as shown in the appendix Figures 6-10 As shown, a spray water supply worm gear 15 that meshes with a spray water supply worm wheel 14 is rotatably mounted on the rear side of the spray drive chamber 13, and a spray water supply motor 16 connected to the spray water supply worm gear 15 is mounted on the rear side of the spray water supply slide 6. The spray water supply motor 16 is connected to a power supply and a controller. When the spray water supply motor 16 is started in the forward direction, it can drive the spray water supply worm gear 15 to rotate in the forward direction. The spray water supply worm gear 15 then drives the spray water supply worm wheel 14 to rotate, thereby driving the spray water supply slide 6 to move towards the front end of the spray water supply slide 4. When the spray water supply slide 6 moves to abut against the front side of the spray water supply slide 4, the spray water supply motor 16 stops rotating in the forward direction and then starts to start in the reverse direction. When the spray water supply motor 16 is started in reverse, it can drive the spray water supply worm gear 15 to rotate in reverse, thereby driving the spray water supply worm wheel 14 to rotate in reverse, thereby driving the spray water supply slide 6 to move from the front end of the spray water supply slide 4 to its rear end until the spray water supply slide 6 is completely inside the spray displacement slide 5. Then the spray water supply motor 16 stops rotating, and the spray displacement slide 5 can drive the spray water supply slide 6 inside it to move to the position of the rear end of the next spray water supply slide 4. The left and right inner walls of the spray displacement slide 5 and the left and right side walls of the multiple spray water supply slides 4 are all provided with slide limit grooves 17, and the slide limit grooves 17 between the spray displacement slide 5 and the spray water supply slides 4 are connected. The left and right sides of the spray water supply slide 6 are all fixedly installed with slide limit blocks 18 that slide in cooperation with the slide limit grooves 17. The spray water supply slide 6 can move from the inside of the spray displacement slide 5 to the inside of the spray water supply slide 4 through the sliding cooperation between the slide limit grooves 17 and the slide limit blocks 18, and will not fall off the inside of the spray water supply slide 4 when it moves.

[0038] Example 4, as shown in the appendix Figure 3 , Figure 7 , Figure 8 , Figure 10 As shown, a displacement drive groove 19 runs through the bottom of the spray displacement chute 3 and the interior of the seedling box 1. A displacement drive screw 20 located below the displacement drive groove 19 is rotatably installed inside the seedling box 1. A displacement drive screw block 21, which is threadedly connected to the displacement drive screw 20, is fixedly installed at the bottom of the spray displacement slide 5. A displacement drive motor connected to the displacement drive screw 20 is fixedly installed inside the seedling box 1. The displacement drive motor is connected to a power supply and a controller. When it is necessary to move the spray displacement slide 5 to the rear end of the next spray water supply chute 4, the displacement drive motor can be started to drive the displacement drive screw 20 to rotate. The displacement drive screw 20 then drives the displacement drive screw block 21, which is threadedly connected to it, to move within the displacement drive groove 19. The displacement drive screw block 21 then drives the spray displacement slide 5 to move. When the spray displacement slide 5 moves to the rear end of one of the spray water supply chute 4, the displacement drive motor stops rotating.

[0039] Example 5, as shown in the appendix Figures 4-10As shown, a displacement sensing switch 23 is installed on the rear side of the spray displacement slide 3 at the position behind each spray water supply slide 4. The displacement sensing switch 23 is electrically connected to the controller. When the displacement drive motor starts and drives the spray displacement slide 5 to move to the rear end position of one of the spray water supply slide 4, the displacement sensing switch 23 can sense that the spray displacement slide 5 is in front of it and send a stop signal to the controller. The controller then stops the displacement drive motor from rotating, thereby realizing the positioning between the spray displacement slide 5 and the spray water supply slide 4. A spray sensor switch 24 is installed on the rear inner wall of the spray displacement slide 5 and on the front side of each spray water supply slide 4. The spray sensor switch 24 is electrically connected to the controller. When the spray water supply motor 16 starts in the forward direction and drives the spray water supply slide 6 to move to its front end in the spray water supply slide 4, the spray water supply slide 6 can abut against the spray sensor switch 24 on the front side of the spray water supply slide 4. The spray sensor switch 24 then sends a stop and reverse start signal to the controller, causing the spray water supply motor 16 to stop rotating. The reverse start causes the spray water supply slide 6 to move towards its rear end within the spray water supply slide 4 until it is fully inside the spray displacement slide 5. When the spray water supply slide 6 is fully inside the spray displacement slide 5, its rear side abuts against the spray sensor switch 24 on the inner rear wall of the spray displacement slide 5. The spray sensor switch 24 then sends a stop signal to the controller, causing the spray water supply motor 16 to stop rotating. Then, the displacement drive motor is restarted to move the spray displacement slide 5 to the position at the rear end of the next spray water supply slide 4.

[0040] Example 6, as shown in the appendix Figures 3-6 , Figure 11 , Figure 12 As shown, the anti-sticking seedling emergence mechanism 10 includes a seedling emergence top plate 25 installed inside the seedling pot 2. A seedling emergence top tube 26 is coaxially fixedly installed on the bottom surface of the seedling emergence top plate 25, penetrating the bottom of the seedling pot 2. The seedling emergence top tube 26 can move up and down at the bottom of the seedling pot 2, thereby driving the seedling emergence top plate 25 to move up and down inside the seedling pot 2, and can also drive the seedling emergence top plate 25 to rotate. A spring plate is installed on the outer side of the bottom end of the seedling emergence top tube 26, and a seedling emergence top tube spring 27 is sleeved on the outer side of the seedling emergence top tube 26. The two ends of the seedling emergence top tube spring 27 abut against the bottom surface of the seedling pot 2 and the top surface of the spring plate, respectively, so that the seedling emergence top plate 25 abuts against the bottom surface inside the seedling pot 2. When seedling emergence is required, the seedling emergence top tube 26 is moved upward, and the seedling emergence top plate 25 can lift the soil upward. The outer side of the seedling top plate 25 is equipped with multiple circumferentially evenly distributed scraper rods 28. Each scraper rod 28 has an anti-adhesion scraper 29 fixedly installed at the end away from the seedling top plate 25, which abuts against the inner wall of the seedling pot 2. When seedlings need to emerge, in order to prevent the soil from sticking to the inner wall of the seedling pot 2, the seedling top tube 26 can be rotated first. The seedling top tube 26 drives the seedling top plate 25 and the multiple scraper rods 28 on its outer side to rotate. The multiple scraper rods 28 then drive the multiple anti-adhesion scrapers 29 to rotate circumferentially against the inner wall of the seedling pot 2, thereby scraping away the soil sticking to the inner wall of the seedling pot 2. Then the seedling top tube 26 can be moved upward, thereby lifting the soil upward through the seedling top plate 25. The staff can then take out the seedlings along with the soil around their roots and transplant them without damaging the seedlings.

[0041] Example 7, as shown in the appendix Figures 4-6 , Figure 11 , Figure 12 As shown, a seedling drive plate 30 is slidably installed inside the seedling box 1. A plurality of seedling drive rods 31 arranged in a rectangular array are fixedly installed on the top surface of the seedling drive plate 30. The top of each seedling drive rod 31 is located inside the bottom end of a seedling tube 26. An anti-adhesion spiral groove 32 is opened on the outer side of each seedling drive rod 31. An anti-adhesion rotating pin 33 is fixedly installed on the inner wall of each seedling tube 26. The anti-adhesion rotating pin 33 is located in the anti-adhesion spiral groove 32. When seedlings need to emerge, the seedling drive plate 30 can be moved upward. The seedling drive plate 30 then drives multiple seedling drive rods 31 to move upward, causing the seedling drive rods 31 to move into the seedling tube 26. The anti-adhesion spiral groove 32 can apply an upward squeezing force to the anti-adhesion rotating pin 33. Since the seedling tube spring 27 is pressed against the seedling pot 2 and the spring plate, the seedling tube 26 will not move upward at this time. Therefore, when the anti-adhesion spiral groove 32 moves upward and applies a spiral squeezing force to the anti-adhesion rotating pin 33, the seedling tube 26 can rotate, thereby driving multiple anti-adhesion scrapers 29 to rotate circumferentially and scrape away the soil that is stuck to the inner wall of the seedling pot 2. When the seedling driving rod 31 is fully inserted into the seedling jacking tube 26 and the bottom end of the seedling jacking tube 26 abuts against the top surface of the seedling driving plate 30, the seedling driving plate 30 continues to move upward, which pushes multiple seedling jacking tubes 26 upward, thereby causing multiple seedling jacking tubes 26 to move upward and lift the soil inside the seedling pot 2 upward through the seedling jacking plate 25, thus realizing the seedling jacking operation without damage.

[0042] Example 8, as shown in the appendix Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, seedling drive slots 34 are penetrated on both the left and right side walls of the seedling box 1. Seedling drive blocks 35 extending from the seedling drive slots 34 to the outside of the seedling box 1 are fixedly installed on both the left and right sides of the seedling drive plate 30. Seedling drive cylinders 36 are fixedly installed on both the left and right sides of the seedling box 1. The seedling drive cylinders 36 are connected to air pumps. The output shaft of each seedling drive cylinder 36 is fixedly connected to the seedling drive block 35 on the same side. When the output shafts of the two seedling drive cylinders 36 extend and retract simultaneously, they can drive the two seedling drive blocks 35 to move up and down in the seedling drive slots 34. The two seedling drive blocks 35 then drive the seedling drive plate 30 to move up and down inside the seedling box 1.

[0043] Example 9, as shown in the appendix Figure 1 , Figures 4-6 As shown, each of the seedling pots 2 has a drainage hole 37 at the bottom, which allows excess water in the seedling pot 2 to drain out, preventing the seedling roots from rotting due to excessive water accumulation inside the seedling pot 2. Several mesh holes 38 are passed through the upper and lower surfaces of the seedling drive plate 30. The seedling box 1 is equipped with a water receiving tray 39 located below the seedling drive plate 30. The water flowing out from the drainage hole 37 flows onto the seedling drive plate 30, and then flows through the several mesh holes 38 into the water receiving tray 39 below for storage. The staff can periodically remove the water receiving tray 39 to clean the wastewater inside.
