Description

Technical Field

[0001] The invention relates to the field of seedling cultivation monitoring, and in particular to a seedling cultivation monitoring device for forest cultivation. Background Art

[0002] Hydroponic tree seedling cultivation is an innovative method of seedling cultivation that does not require soil. Instead, tree cuttings or seedlings are placed in a culture box filled with nutrient solution for cultivation.

[0003] In the prior art, when trees are hydroponically grown as seedlings, the nutrient solution flows through each seedling in turn. When one of the seedlings is infected with pathogens, the pathogens may flow with the nutrient solution and infect other seedlings, thereby requiring monitoring of the seedlings. When diseased plants are detected, timely remedial measures are taken. However, existing video monitoring equipment may be affected by external factors during monitoring, resulting in misjudgment. For example, due to lighting conditions such as strong light, shadows, and backlighting, the captured images of the seedlings may easily appear reflective, too dark, or have uneven light and shadow, affecting the accurate judgment of the seedlings' morphology, color, health status and other characteristics. Normal seedlings may be mistakenly judged as diseased plants, and unnecessary culling may be performed, thereby increasing the cost of seedling cultivation. Summary of the invention

[0010] Preferably, a water collecting cylinder is fixed inside the liquid discharge port, the water collecting cylinder is funnel-shaped, and the small-diameter end of the water collecting cylinder faces the elastic sheet.

[0011] Preferably, an isolation ring is fixed inside the floating ring, the isolation ring is arranged between the liquid inlet and the liquid outlet, and an overflow channel is arranged between the top of the isolation ring and the inner top surface of the floating ring.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When diseased plants are monitored, the nutrient solution is transported into the delivery pipe through the nutrient solution delivery equipment, and new nutrient solution is introduced into the hydroponic cavity of the diseased plants through the delivery pipe, so that the liquid level in the hydroponic cavity of the diseased plants rises. Under the action of buoyancy, the floating ring can push the planting basket and seedlings upward, so that the diseased plants are raised as a whole and protrude from the seedling group, so as to conduct secondary monitoring and avoid misjudgment.

[0016] Second, by raising the position of the diseased plants, it is helpful to change the light position on their surface, thereby reducing the adverse effects of light on monitoring, and avoiding being blocked by other seedlings, which would affect the comprehensive monitoring of the seedlings. If the seedling is determined to be a diseased plant during the second monitoring, since it protrudes out of the seedling group, it is also convenient for staff or robots to identify it and take it out in a timely and quick manner.

[0017] 3. When adding nutrient solution into the hydroponic chamber, the nutrient solution enters the inside of the floating ring from the liquid inlet at the bottom of the floating ring and is discharged from the multiple drainage ports on the side wall of the floating ring, so that the liquid can be evenly discharged around the floating ring. The liquid fills the gap between the floating ring and the guide tube, which can not only limit the left and right swing of the floating ring, but also play a lubricating role in the process of the floating ring rising, ensuring the stable rise of the floating ring, protecting the root system of the plant, avoiding misjudgment of the monitoring head, and causing damage to the plant during the rising process. In addition, by arranging an isolation ring inside the floating ring, after the liquid enters, it first gathers on one side of the isolation ring. When one side of the isolation ring is full, the liquid overflows from the overflow channel at the top of the isolation ring to the other side of the isolation ring. Under the overflow effect, the liquid can form a relatively regular and uniform flow distribution at the overflow channel position and then flow into each drainage port, thereby ensuring the uniformity of the drainage and maintaining the stability of the floating ring rising.

[0018] Fourth, by opening multiple vertical grooves on the inner wall of the guide tube, the positions of the vertical grooves correspond to the positions of the drainage ports one by one, so that after the liquid is discharged from the drainage port, it can immediately enter the vertical grooves, descend along the vertical grooves, and finally flow out from the through groove position. A restraining force is generated between the vertical grooves and the liquid, thereby reducing the rotation tendency of the floating ring, ensuring that the floating ring can stably rise vertically, which is beneficial to further protect the root system of the seedlings.

DETAILED DESCRIPTION

[0029] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0030] like Figures 1 to 9The seedling cultivation monitoring device for forest cultivation shown in the figure comprises a monitoring frame 1 and a plurality of horizontally arranged hydroponic boxes 2, the hydroponic boxes 2 being fixed in the monitoring frame 1, the two ends of the hydroponic boxes 2 being respectively provided with a water inlet 3 and a water outlet 4, a connecting pipe 5 being provided between adjacent hydroponic boxes 2, the connecting pipe 5 connecting the water inlet 3 of one hydroponic box 2 with the water outlet 4 of another hydroponic box 2, a slide rail 6 being fixed on the side wall of the monitoring frame 1, a monitoring head 7 being provided on the slide rail 6, a driving assembly being provided in the slide rail 6, the driving assembly being used to drive the monitoring head 7 to move along the slide rail 6, each hydroponic box 2 having a plurality of hydroponic chambers 8 inside, adjacent hydroponic boxes 2 A connecting hole 9 is provided between the hydroponic chambers 8, a regulating valve 10 is fixedly installed in the connecting hole 9, an insertion port 11 is provided on the top of each hydroponic chamber 8, a guide tube 12 is fixed inside the insertion port 11, a support ring 13 is fixed at the bottom of the guide tube 12, a floating ring 14 is inserted inside the guide tube 12, the floating ring 14 is placed on the support ring 13, a planting basket 15 is placed in the middle of the floating ring 14, support rods 16 are fixed around the planting basket 15, and the ends of the support rods 16 extend to the top of the floating ring 14, a delivery pipe 17 is fixed on the side wall of each hydroponic chamber 8, and the delivery pipe 17 is connected to an external nutrient solution delivery device.

[0031] Specifically, in the prior art, when hydroponically growing trees, the nutrient solution flows through each seedling in turn. When one of the seedlings is infected by pathogens, the pathogens may flow with the nutrient solution and infect other seedlings, and then the seedlings need to be monitored. When diseased plants are detected, remedial measures are taken in a timely manner. However, the existing video monitoring equipment may be affected by external factors during monitoring, resulting in misjudgment. For example, due to the influence of lighting conditions, such as strong light, shadow, backlight, etc., the captured seedling images may be reflective, too dark, or uneven in light and shadow, which affects the accurate judgment of the seedlings' morphology, color, health status and other characteristics, and may mistake normal seedlings for diseased plants. The present invention can solve the above problem. The specific working method is as follows: first, the seedlings are planted in the planting basket 15, and the planting basket 15 is inserted into the opening in the middle of the floating ring 14. The planting basket 15 is supported by the support rods 16 around the planting basket 15 and in contact with the top of the floating ring 14. This placement method is convenient for manual or mechanical hands to quickly and conveniently remove the planting basket 15 when diseased plants are subsequently monitored. Furthermore, when raising seedlings, the nutrient solution is transported into each hydroponic box 2 through an external nutrient solution transporting device, and the liquid level of the nutrient solution is lower than the height of the floating ring 14, thereby ensuring the stability of the floating ring 14 during normal seedling raising. During the seedling raising process, the seedling raising is monitored by the monitoring head 7. The monitoring head 7 is a camera. By collecting seedling raising picture information, the growth status of the seedling raising is analyzed. When a diseased plant is detected, the regulating valves 10 of each hydroponic chamber 8 are closed to make each hydroponic chamber 8 independent of each other, which is conducive to avoiding the spread of pathogens. Furthermore, in order to avoid misjudgment, when a diseased plant is detected, the nutrient solution is transported into the delivery pipe 17 through the nutrient solution delivery equipment, and new nutrient solution is introduced into the hydroponic chamber 8 of the diseased plant through the delivery pipe 17, so that the liquid level in the hydroponic chamber 8 of the diseased plant rises. Under the action of buoyancy, the floating ring 14 can push the planting basket 15 and the seedling upward, so that the diseased plant rises as a whole. On the one hand, by raising the seedlings through the floating ring 14, the seedlings can be automatically floated, and there is no need to install an electric or pneumatic push rod in each hydroponic chamber 8, which is beneficial to reducing the amount of parts installed and saving costs. On the other hand, by raising the position of the diseased plants, it is beneficial to change the light position on their surface, thereby reducing the adverse effects of light on monitoring, and also avoiding other seedlings from blocking them and affecting the comprehensive monitoring of the seedlings. If the seedling is determined to be a diseased plant during the secondary monitoring, since it protrudes from the seedling group, it is also convenient for staff or manipulators to identify it and take it out in a timely and rapid manner.

[0032] As a further embodiment of the present invention, the interior of the floating ring 14 is a hollow structure, an air cushion 21 is fixed to the bottom of the floating ring 14, the outer diameter of the floating ring 14 is smaller than the inner diameter of the guide tube 12, a liquid inlet 18 is provided on the bottom surface of the floating ring 14, a telescopic hose 19 is fixed to one end of the delivery tube 17, the telescopic hose 19 is fixedly connected to the liquid inlet 18, and a plurality of liquid discharge ports 20 are provided on the side wall of the floating ring 14.

[0033] Specifically, by making the outer diameter of the floating ring 14 smaller than the inner diameter of the guide tube 12, the floating ring 14 does not contact the guide tube 12 during the rising process, avoiding sliding friction between the floating ring 14 and the guide tube 12, which is conducive to the stable and smooth rise of the floating ring 14. However, the gap between the floating ring 14 and the guide tube 12 will also cause the floating ring 14 to swing left and right during the rising process. The root system of some tree seedlings is relatively fragile, and the swing of the floating ring 14 may damage the root system of the seedlings. Therefore, in this embodiment, a plurality of drainage ports 20 are evenly opened on the side wall of the floating ring 14, and the drainage port 20 is connected to the guide tube 12 through the telescopic hose 19. The delivery pipe 17 is connected to the inside of the floating ring 14. When the nutrient solution is added to the hydroponic chamber 8, the nutrient solution enters the inside of the floating ring 14 from the liquid inlet 18 at the bottom of the floating ring 14, and is discharged from the multiple drainage ports 20 on the side wall of the floating ring 14, so that the liquid can be evenly discharged from the four sides of the floating ring 14. The liquid fills the gap between the floating ring 14 and the guide tube 12, which can not only limit the left and right swing of the floating ring 14, but also play a lubricating role in the process of the floating ring 14 rising, ensuring that the floating ring 14 rises stably, protecting the root system of the plant, and avoiding misjudgment of the monitoring head 7, which may cause damage to the plant during the rising process.

[0034] As a further embodiment of the present invention, a plurality of vertical grooves 22 are formed on the inner ring surface of the guide tube 12 , and the positions of the vertical grooves 22 correspond to the positions of the drain ports 20 . A plurality of through grooves 40 are formed on the surface of the support ring 13 .

[0035] Specifically, the floating ring 14 may rotate during the rising process, which may have an adverse effect on the fragile root system of the seedlings. This embodiment opens a plurality of vertical grooves 22 on the inner wall of the guide tube 12. The positions of the vertical grooves 22 correspond to the positions of the drain ports 20 one by one, so that after the liquid is discharged from the drain ports 20, it can immediately enter the vertical grooves 22, descend along the vertical grooves 22, and finally flow out from the through grooves 40. A restraining force is generated between the vertical grooves 22 and the liquid, thereby reducing the rotation tendency of the floating ring 14 and ensuring that the floating ring 14 can rise vertically stably, which is beneficial to further protect the root system of the seedlings. Furthermore, since an air cushion 21 is fixed to the bottom of the floating ring 14, the drain port 20 is always above the liquid surface during the rising process of the floating ring 14, which is also beneficial to continuously maintain the restraining force between the vertical grooves 22 and the liquid during the rising process.

[0036] As a further implementation scheme of the present invention, a limiting cylinder 23 is arranged inside a part of the discharge port 20, one end of the limiting cylinder 23 is inserted into the vertical groove 22, and the other end of the limiting cylinder 23 is connected to a plurality of flip rods 24 through a connecting assembly, and a plurality of U-shaped rods 25 are fixed on the inner wall of the discharge port 20, and the flip rods 24 are rotatably connected to the U-shaped rods 25, and an elastic sheet 26 is commonly fixed to one end of the plurality of flip rods 24 near the middle of the discharge port 20.

[0037] Specifically, during the rising process of the floating ring 14, the vertical groove 22 needs to be aligned with the drainage port 20 to limit the rotation of the floating ring 14. In order to avoid the vertical groove 22 and the drainage port 20 from being misaligned before the floating ring 14 rises, this embodiment sets a limiting cylinder 23 in part of the drainage port 20. When the drainage port 20 is not draining water, the limiting cylinder 23 extends out of the drainage port 20 and is inserted into the vertical groove 22 to limit the floating ring 14. It should be noted that, if Figure 4 As shown, under the pulling action of the elastic sheet 26, the flip rod 24 is in a vertical state, maintaining the limiting state of the limiting cylinder 23, and when draining water, under the action of water pressure, the elastic sheet 26 moves toward the outside of the drainage port 20, and pulls the end of the flip rod 24 to move toward the outside of the drainage port 20, and the flip rod 24 is rotatably connected with the U-shaped rod 25, and the U-shaped rod 25 is fixed on the inner wall of the drainage port 20 and is in a stationary state. When the bottom of the flip rod 24 is pulled, the flip rod 24 can flip around the U-shaped rod 25 and pull the limiting cylinder 23 to move toward the inside of the drainage port 20, so that the limiting cylinder 23 is separated from the vertical groove 22, avoiding sliding friction between the vertical groove 22 during the rising process, which will adversely affect the stable rising of the floating ring 14.

[0038] As a further embodiment of the present invention, the connecting assembly includes a connecting seat 27, the surface of which is provided with an insertion groove 28, a rotating rod 29 is inserted into the insertion groove 28, and the rotating rod 29 is fixed at the end of the flip rod 24, and the length of the insertion groove 28 is greater than the outer diameter of the rotating rod 29.

[0039] Specifically, under the pulling action of the elastic sheet 26, the top end of the flip rod 24 flips toward the inside of the discharge port 20 and has a tendency to flip downward. By providing a larger insertion groove 28, when the flip rod 24 flips, the rotating rod 29 can move in the insertion groove 28 to make way, avoiding jamming, which is beneficial to maintaining the normal operation of the entire device.

[0040] As a further embodiment of the present invention, a water collecting cylinder 30 is fixed inside the liquid discharge port 20 . The water collecting cylinder 30 is funnel-shaped, and the small-diameter end of the water collecting cylinder 30 faces the elastic sheet 26 .

[0041] Specifically, a gap is left between the edge of the elastic sheet 26 and the discharge port 20 to facilitate the passage of liquid, but the position of the gap will disperse the liquid pressure and may affect the driving force on the elastic sheet 26. This embodiment sets a water collecting cylinder 30 so that the liquid can directly impact the middle part of the elastic sheet 26, so that the liquid pressure is more concentrated, thereby maintaining the elastic sheet 26 with a stable tendency to move outward. In addition, the elastic sheet 26 is made of elastic rubber material. After being impacted by the liquid, a depression is formed in the middle, which is also conducive to gathering the liquid, making the liquid pressure more concentrated, further ensuring that the elastic sheet 26 has a stable tendency to move outward, and further ensuring the stable separation state of the limit cylinder 23 and the inner wall of the vertical groove 22.

[0042] As a further embodiment of the present invention, an isolation ring 31 is fixed inside the floating ring 14 . The isolation ring 31 is arranged between the liquid inlet 18 and the liquid outlet 20 . An overflow channel 32 is arranged between the top of the isolation ring 31 and the inner top surface of the floating ring 14 .

[0043] Specifically, the liquid enters the floating ring 14 from the liquid inlet 18. It is known from the prior art that the liquid is easily discharged from the liquid discharge port 20 near the liquid inlet 18, resulting in uneven liquid discharge, which in turn affects the stable rise of the floating ring 14. In this embodiment, an isolation ring 31 is set inside the floating ring 14. After the liquid enters, it first gathers on one side of the isolation ring 31. When one side of the isolation ring 31 is full, the liquid overflows from the overflow channel 32 at the top of the isolation ring 31 to the other side of the isolation ring 31. Under the overflow effect, the liquid can form a relatively regular and uniform flow distribution at the overflow channel 32 and then flow into each liquid discharge port 20, thereby ensuring the uniformity of the liquid discharge and maintaining the stability of the rise of the floating ring 14.

[0044] As a further implementation scheme of the present invention, a drainage groove 33 is provided on the inner ring surface of the floating ring 14, and a sealing component is provided on the side wall of the floating ring 14. The sealing component is used to seal the drainage groove 33 when liquid is injected. The sealing component includes a sealing ring 34, which is vertically slidably arranged inside the floating ring 14. An annular groove 35 is provided at the bottom of the sealing ring 34, and the annular groove 35 is connected to the liquid inlet 18. A top hole 41 is provided on the top surface of the annular groove 35, and the top hole 41 is connected to the inside of the floating ring 14. A limit ring 36 is fixed on the inner wall of the floating ring 14, and the limit ring 36 is arranged above the sealing ring 34. The inner diameter of the top hole 41 is smaller than the inner diameter of the liquid inlet 18.

[0045] Specifically, in the above embodiment, after the drainage is completed, part of the liquid will remain on one side of the isolation ring 31. In this embodiment, by providing a drainage groove 33, in the initial state, the drainage groove 33 is in an open state, so that the liquid remaining in the floating ring 14 can be discharged from the drainage groove 33. When the liquid is transported from the delivery pipe 17 to the inside of the floating ring 14, the liquid first enters the annular groove 35, and then flows out from the top hole 41 and enters the inside of the floating ring 14. Since the inner diameter of the top hole 41 is smaller than the inner diameter of the liquid inlet 18, the liquid first flows into the annular groove 35, and then flows out from the top hole 41 and enters the inside of the floating ring 14. , so that the speed of discharging liquid from the top hole 41 is lower than the speed of liquid inlet from the liquid inlet 18, so that under the action of hydraulic pressure, the sealing ring 34 can be lifted up to seal the drainage groove 33, ensuring that the drainage groove 33 is sealed during the liquid inlet process, so that the liquid can only flow out from the drainage port 20, and by setting a limit ring 36, the top of the sealing ring 34 can be blocked to prevent the sealing ring 34 from rising too far and detaching from the drainage groove 33, while also maintaining the hydraulic jacking state below the sealing ring 34.

[0046] As a further embodiment of the present invention, the top hole 41 is arranged on a side away from the liquid inlet 18 .

[0047] Specifically, by setting the top hole 41 on the side away from the liquid inlet 18, after the liquid enters the annular groove 35 from the liquid inlet 18, it must first flow along the annular groove 35, fill the annular groove 35, and then be discharged from one end of the liquid inlet 18. This is conducive to forming a uniform driving force at the bottom of the sealing ring 34, thereby ensuring the stability of the sealing function of the sealing ring 34.

[0048] As a further embodiment of the present invention, the driving assembly includes a slider 37, which is fixed to the monitoring head 7, and the slider 37 is slidably connected to the slide rail 6. A screw 38 is threadedly connected to the slider 37, and both ends of the screw 38 are rotatably connected to the slide rail 6. A motor 39 is provided at one end of the screw 38, and the output shaft of the motor 39 is coaxially fixed to the screw 38.

[0049] Specifically, by starting the motor 39, the screw rod 38 can be driven to rotate, thereby driving the slider 37 to move on the slide rail 6, and the slider 37 drives the monitoring head 7 to move to monitor the seedlings at different positions.

[0050] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
