Description

Technical Field

[0001] The present invention relates to the technical field of apple sapling cultivation, and specifically relates to a circumferential apple sapling breeding irrigation device and method. Background Art

[0002] Apples are one of the most widely cultivated and sold fruits globally, with a long cultivation history and a wide distribution range. When breeding apple saplings, irrigation is required to provide water and nutrients for the apple saplings and promote the growth of the apple saplings.

[0003] Traditional sprinkler irrigation equipment has blind spots and insufficient coverage in the edge area (coverage rate is only 60 - 70%), resulting in uneven root system development. The spacing of the fixed drip irrigation pipes is not adjustable and cannot adapt to different crown sizes. Equipment needs to be replaced during the seedling stage and the adult plant stage. At the same time, it is difficult to adjust the height and coverage radius, and it cannot adapt to the complex terrains of mountain terraced fields or greenhouse facilities. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a circumferential apple sapling breeding irrigation device and method in view of the above - mentioned deficiencies of the prior art. The device has a simple structure, meets the basic irrigation requirements through the outer ring pipe, conducts precise irrigation through the inner ring pipe, and irrigates the apple saplings through the cooperation of the inner ring pipe and the outer ring pipe. It has a high coverage rate, is convenient for adjustment and use, is easy to install and recycle, and can be popularized and applied.

[0005] To solve the above - mentioned technical problem, the technical solution adopted by the present invention is: a circumferential apple sapling breeding irrigation device, characterized in that it includes an irrigation mechanism and a lifting mechanism for driving the irrigation mechanism to lift. The irrigation mechanism includes an inner ring pipe, an outer ring pipe and two connecting pipes. Both the inner ring pipe and the outer ring pipe include a straight pipe section and a bent pipe section. The two ends of the bent pipe section are respectively fixedly communicated with the straight pipe sections. The straight pipe sections approaching each other can drive the deformation of the bent pipe section, change the diameter of the bent pipe section, and thus change the irrigation range of the bent pipe section.

[0006] Both ends of the inner ring pipe are slidably sleeved with both ends of one of the connecting pipes, both ends of the outer ring pipe are slidably sleeved with both ends of the other connecting pipe, and the two connecting pipes are fixedly connected with an interface through a tee pipe. The interface is used to connect the irrigation pipe. A plurality of rotating nozzles are equidistantly arranged on the inner circumference of the inner ring pipe, and a plurality of pressure - compensating drip emitters are equidistantly installed at the bottom end of the outer ring pipe. The rotating nozzles are used to irrigate the upper and middle parts of the apple saplings. The rotating nozzles perform rotating spraying, which expands the coverage range. The pressure - compensating drip emitters are used to irrigate the root systems of the apple saplings and also play a role in reducing the temperature of the root environment.

[0007] Sealing rings are slidably sleeved on both sides inside the connecting pipe. The outer ends of the sealing rings are fixedly connected to the inner ring pipe or the outer ring pipe. Miniature telescopic motors for driving the sliding of the sealing rings are fixedly installed on both sides inside the connecting pipe. The miniature telescopic motors drive the sealing rings to approach or move away from each other inside the inner ring pipe or the outer ring pipe, driving the inner ring pipe or the outer ring pipe to deform, so that the distance between the rotating nozzles or pressure-compensating drippers changes, thereby achieving the purpose of adjusting the irrigation coverage area.

[0008] The miniature telescopic motors inside the inner ring pipe and the outer ring pipe expand and contract synchronously, causing the inner ring pipe and the outer ring pipe to deform synchronously.

[0009] The two connecting pipes are fixedly connected through a connecting bracket. A plurality of adjusting buckles are further arranged on the inner ring pipe and the outer ring pipe. The adjusting buckles serve to connect the inner ring pipe and the outer ring pipe. An angle adjusting mechanism for driving the rotating nozzle to rotate relative to the outer ring pipe is arranged on the adjusting buckle. The angle adjusting mechanism can drive the rotating nozzle to rotate in the up and down directions, thereby achieving the purpose of adjusting the coverage area of the rotating nozzle.

[0010] Preferably, the lifting mechanism includes a base, a lead screw, a lead screw nut, a guide rod, a connecting bracket, and a servo motor. Three ground spikes for fixing the lifting mechanism to the ground are fixedly installed at the bottom end of the base. The three ground spikes are arranged in a triangular pattern, which is more stable. The lead screw is rotatably installed on the base. The lead screw nut is threadedly sleeved on the lead screw. The connecting bracket is fixedly connected to the lead screw nut. The connecting bracket is slidably connected to the guide rod. The servo motor is fixedly installed on the base. The servo motor is used to drive the lead screw to rotate.

[0011] The servo motor drives the lead screw to rotate, causing the lead screw nut to drive the connecting bracket to move up and down along the lead screw, driving the irrigation mechanism to lift, and adjusting the height positions of the rotating nozzles and the pressure-compensating drippers.

[0012] Preferably, a plurality of installation holes are equidistantly formed on the inner circumference of the inner ring pipe. The installation holes are in a long strip shape. An installation pipe is slidably installed in the installation holes. The outer end of the installation pipe is fixedly communicated with the rotating nozzle. Inner sealing plates and outer sealing plates are fixedly installed on both sides of the installation pipe. The inner sealing plates and the outer sealing plates are in an arc shape. The inner sealing plates are closely attached to the inner wall of the inner ring pipe, and the outer sealing plates are closely attached to the outer wall of the inner ring pipe.

[0013] When the installation pipe slides up and down, the inner sealing plates and the outer sealing plates seal the installation holes to prevent liquid leakage.

[0014] Preferably, angle adjusting mechanisms are respectively fixedly installed at both ends of the adjusting buckle. The end of the output shaft of the angle adjusting mechanism is fixedly connected to the outer sealing plate. A connecting rod is fixedly installed between adjacent inner sealing plates, enabling multiple inner sealing plates to move synchronously.

[0015] Preferably, the angle adjustment mechanism includes an arc-shaped bushing, an output shaft, and an angle telescopic motor. The arc-shaped bushing is fixedly installed at both ends of the adjustment buckle. The output shaft is slidably installed in the arc-shaped bushing. The output shaft is arc-shaped. An angle telescopic motor is fixedly installed in the arc-shaped bushing. When the output shaft of the angle telescopic motor expands and contracts, it can drive the output shaft to slide relative to the arc-shaped bushing, thereby pushing the outer sealing plate to rotate relative to the inner ring pipe and driving the rotating nozzle to rotate relative to the inner ring pipe. Since the movement trajectory of the output shaft of the angle adjustment mechanism is arc-shaped, the stroke of the output shaft of the angle telescopic motor is limited, and this stroke is less than the radian of the arc-shaped bushing to ensure that the output shaft of the angle telescopic motor can drive the output shaft to move.

[0016] And because the radian of the arc-shaped bushing is small, this part can be approximately regarded as a straight line, and the movement principle is similar to that of a linear telescopic mechanism. As shown in the figure, from top to bottom are the states of the angle telescopic motor contracting, in the normal state, and extending, which are also the states of the output shaft contracting, in the normal state, and extending.

[0017] When the output shaft of the upper angle adjustment mechanism extends, the output shaft of the lower angle adjustment mechanism contracts synchronously, and the outer sealing plate is pushed by the upper angle adjustment mechanism to rotate relative to the inner ring pipe; when the output shaft of the upper angle adjustment mechanism contracts, the output shaft of the lower angle adjustment mechanism extends synchronously, and the outer sealing plate is pushed by the lower angle adjustment mechanism to rotate relative to the inner ring pipe.

[0018] The output shaft of the angle adjustment mechanism expands and contracts, driving the outer sealing plate to rotate, thereby driving the rotating nozzle to rotate up and down. Under the action of the connecting rod, the rotating nozzle connected with the adjustment buckle drives the other rotating nozzles to rotate up and down together, achieving the purpose of synchronous adjustment, and the adjustment process is efficient and unified.

[0019] The angle adjustment mechanism can also select a hydraulic cylinder that can output a curvilinear motion, and the outer sealing plate is pushed by the hydraulic cylinder to rotate relative to the inner ring pipe.

[0020] Preferably, the tail end of the rotating nozzle is rotatably sleeved in the installation pipe. The tail end of the rotating nozzle is of a gradually shrinking outlet type. A turbine blade is fixedly installed in the rotating nozzle, and the turbine blade is used to drive the rotating nozzle to rotate relative to the installation pipe.

[0021] Water flows out along the installation pipe to the rotating nozzle. Due to the gradually shrinking outlet, the water flow generates a vortex, which pushes the turbine blade to rotate. The turbine blade drives the rotating nozzle to rotate relative to the installation pipe, spraying rotating mist and watering the apple seedlings.

[0022] Preferably, detachable end caps are provided on both sides of the interface. The irrigation branch pipe can be connected from one side of the interface, and the other side is closed by the detachable end cap, which is convenient for installation. An electromagnetic valve is provided on the tee pipe. The electromagnetic valve is a T-shaped valve, which is convenient for remote control. The interface can communicate with the inner ring pipe or the outer ring pipe, and can also connect or disconnect the inner ring pipe and the outer ring pipe at the same time.

[0023] Preferably, a phase change layer is embedded in the inner ring pipe and the outer ring pipe. The phase change layer is made of a paraffin-based phase change material. The phase change layer is used to absorb the ambient heat. When the outside ambient temperature is lower than ℃, the phase change layer releases the stored heat to prevent root zone freezing damage.

[0024] Preferably, a temperature and humidity sensor and a camera can be provided on the device. The ambient temperature and humidity are monitored through the temperature and humidity sensor, and the operation state of the device and the growth environment and state of the apple seedlings are detected through the camera. The micro telescopic motor, the servo motor, the angle telescopic motor and the electromagnetic valve are all electrically connected to the control system connecting the temperature and humidity sensor and the camera to realize remote monitoring and operation.

[0025] A circumferential apple seedling breeding irrigation method uses the above-mentioned circumferential apple seedling breeding irrigation equipment, and includes the following steps: S1. The staff lays the irrigation pipe in the seedling raising area, installs the circumferential apple seedling breeding irrigation equipment beside each apple seedling, and connects the irrigation pipe with the interface through the irrigation branch pipe; S2. According to the plant height of the apple seedlings, the height of the irrigation mechanism is adjusted through the lifting mechanism, so that the inner ring pipe and the outer ring pipe move to a suitable irrigation height. The angle adjustment mechanism drives the rotating nozzle on the inner ring pipe to rotate relative to the outer ring pipe, so that the rotating nozzle accurately faces the apple seedlings; S3. Open the electromagnetic valve on the tee pipe. The irrigation water in the irrigation pipe enters the inner ring pipe and the outer ring pipe through the tee pipe. The rotating nozzle on the inner ring pipe rotates under the action of water pressure and sprays atomized water to irrigate the upper and middle parts of the apple seedlings at the same time. The pressure compensating drip head at the bottom of the outer ring pipe irrigates the roots of the apple seedlings; S4. As the apple seedlings grow, the height of the irrigation mechanism is adjusted through the lifting mechanism, the angle of the rotating nozzle relative to the outer ring pipe is adjusted through the angle adjustment mechanism, and the sealing ring is driven to slide by the micro telescopic motor to adjust the inner diameters of the inner ring pipe and the outer ring pipe to adapt to the height and crown diameter of the apple seedlings; S5. In the above steps, liquid fertilizer or insecticide can be added to the irrigation pipe according to the breeding requirements.

[0026] The present invention has the following advantages compared with the prior art: 1. The present invention is provided with a lifting mechanism to drive the watering mechanism to lift. The middle and upper parts of apple seedlings are sprayed by the rotating nozzles on the inner ring pipe of the watering mechanism, and the roots of apple seedlings are drip-irrigated by the pressure-compensating drippers on the outer ring pipe. By combining drip irrigation with rotating spraying, the coverage range is improved. The rotating nozzles have a large coverage radius and are not affected by wind speed. Moreover, the angle of the rotating nozzles relative to the inner ring pipe can be changed by adjusting the angle adjustment mechanism on the buckle to adapt to the size of the apple seedling crowns for precise spraying.

[0027] 2. The inner ring pipe and the outer ring pipe in the present invention include straight pipe sections and bent pipe sections. The two ends of the bent pipe section are respectively fixedly connected to the straight pipe sections. The straight pipe sections can be driven to approach each other by a micro telescopic motor, which can drive the bent pipe section to deform and change the diameter of the bent pipe section, so that the distance between the rotating nozzles and the pressure-compensating drippers changes, thereby achieving the purpose of adjusting the watering coverage range to adapt to the watering requirements of apple seedlings in different growth periods.

[0028] 3. The inner ring pipe and the outer ring pipe are connected by an adjusting buckle in the present invention. An angle adjustment mechanism is also provided on the adjusting buckle. The output shaft is extended and retracted by the extension and retraction of the angle telescopic motor, thereby driving the outer sealing plate connected to the rotating nozzle to rotate relative to the inner ring pipe, making the rotating nozzle rotate relative to the inner ring pipe, achieving the purpose of adjusting the angle of the rotating nozzle, and effectively changing the coverage range of the rotating nozzle.

[0040] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementations disclosed below.

[0041] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0042] As Figures 1-9 shown, the present invention provides a circumferential apple seedling breeding irrigation device, including an irrigation mechanism and a lifting mechanism 8 for driving the irrigation mechanism to lift. The irrigation mechanism includes an inner ring pipe 1, an outer ring pipe 2 and two connecting pipes 3. Both the inner ring pipe 1 and the outer ring pipe 2 include a straight pipe section and a bent pipe section. The two ends of the bent pipe section are respectively fixedly communicated with the straight pipe sections. The straight pipe sections approaching each other can drive the deformation of the bent pipe section, change the diameter of the bent pipe section, and thus change the irrigation range of the bent pipe section.

[0043] Both ends of the inner ring pipe 1 are slidably sleeved with both ends of one of the connecting pipes 3. Both ends of the outer ring pipe 2 are slidably sleeved with both ends of the other connecting pipe 3. The two connecting pipes 3 are fixedly connected with an interface 5 through a tee pipe 4. The interface 5 is used to communicate with an irrigation pipe. A plurality of rotating spray heads 101 are equidistantly arranged on the inner circumference of the inner ring pipe 1. A plurality of pressure-compensating drip emitters 201 are equidistantly installed at the bottom end of the outer ring pipe 2. The rotating spray heads 101 are used to irrigate the middle and upper parts of the apple seedlings. The rotating spray heads 101 perform rotating spraying, expanding the coverage range. The pressure-compensating drip emitters 201 are used to irrigate the roots of the apple seedlings and also play a role in reducing the temperature of the root environment.

[0044] Sealing rings 301 are slidably sleeved on both sides inside the connecting pipe 3. The outer ends of the sealing rings 301 are fixedly connected to the inner ring pipe 1 or the outer ring pipe 2. The two ends of the inner ring pipe 1 and the outer ring pipe 2 are respectively connected to a group of sealing rings 301 inside the same connecting pipe 3.

[0045] Miniature telescopic motors 302 for driving the sliding of the sealing rings 301 are fixedly installed on both sides inside the connecting pipe 3. The miniature telescopic motors 302 drive the sealing rings 301 to approach or move away from each other inside the inner ring pipe 1 or the outer ring pipe 2, driving the inner ring pipe 1 or the outer ring pipe 2 to deform, so that the distance between the rotary nozzles 101 or the pressure-compensating drippers 201 changes, thereby achieving the purpose of adjusting the irrigation coverage range.

[0046] The miniature telescopic motors 302 inside the inner ring pipe 1 and the outer ring pipe 2 expand and contract synchronously, so that the inner ring pipe 1 and the outer ring pipe 2 deform synchronously.

[0047] The two connecting pipes 3 are fixedly connected through a connecting bracket 805. A plurality of adjusting buckles 6 are further arranged on the inner ring pipe 1 and the outer ring pipe 2. The adjusting buckles 6 play a role in connecting the inner ring pipe 1 and the outer ring pipe 2. An angle adjusting mechanism 7 for driving the rotary nozzle 101 to rotate relative to the outer ring pipe 2 is arranged on the adjusting buckle 6. The angle adjusting mechanism 7 can drive the rotary nozzle 101 to rotate in the up and down directions, thereby achieving the purpose of adjusting the coverage range of the rotary nozzle 101.

[0048] In this embodiment, the lifting mechanism 8 includes a base 801, a lead screw 802, a lead screw nut 803, a guide rod 804, a connecting bracket 805 and a servo motor 806. Three ground spikes for fixing the lifting mechanism 8 on the ground are fixedly installed at the bottom end of the base 801. The three ground spikes are arranged in a triangular pattern, which is more stable. The lead screw 802 is rotatably installed on the base 801. The lead screw nut 803 is threadedly sleeved on the lead screw 802. The connecting bracket 805 is fixedly connected to the lead screw nut 803. The connecting bracket 805 is slidably connected to the guide rod 804. The servo motor 806 is fixedly installed on the base 801. The servo motor 806 is used to drive the lead screw 802 to rotate.

[0049] The servo motor 806 drives the lead screw 802 to rotate, so that the lead screw nut 803 drives the connecting bracket 805 to move up and down along the lead screw 802, driving the irrigation mechanism to lift and adjusting the height positions of the rotary nozzles 101 and the pressure-compensating drippers 201.

[0050] In this embodiment, a plurality of installation holes are equidistantly formed in the inner circumference of the inner ring pipe 1. The installation holes are strip-shaped. An installation pipe 102 is slidably installed in the installation holes. The outer end of the installation pipe 102 is fixedly communicated with a rotary nozzle 101. Inner sealing plates 103 and outer sealing plates 104 are fixedly installed on both sides of the installation pipe 102. The inner sealing plates 103 and the outer sealing plates 104 are arc-shaped. The inner sealing plates 103 are closely attached to the inner wall of the inner ring pipe 1, and the outer sealing plates 104 are closely attached to the outer wall of the inner ring pipe 1.

[0051] When the installation pipe 102 slides up and down, the inner sealing plates 103 and the outer sealing plates 104 seal the installation holes to prevent liquid leakage.

[0052] In this embodiment, angle adjustment mechanisms 7 are respectively fixedly installed at both ends of the adjustment buckle 6. The end of the output shaft 702 of the angle adjustment mechanism 7 is fixedly connected to the outer sealing plate 104. A connecting rod 105 is fixedly installed between adjacent inner sealing plates 103, enabling the plurality of inner sealing plates 103 to move synchronously.

[0053] In this embodiment, the angle adjustment mechanism 7 includes an arc-shaped shaft sleeve 701, an output shaft 702, and an angle expansion and contraction motor 703. The arc-shaped shaft sleeve 701 is fixedly embedded in both ends of the adjustment buckle 6. The output shaft 702 is slidably installed in the arc-shaped shaft sleeve 701. The output shaft 702 is arc-shaped. An angle expansion and contraction motor 703 is fixedly installed in the arc-shaped shaft sleeve 701. When the output shaft of the angle expansion and contraction motor 703 expands and contracts, it can drive the output shaft 702 to slide relative to the arc-shaped shaft sleeve 701, thereby pushing the outer sealing plate 104 to rotate relative to the inner ring pipe 1 and driving the rotary nozzle 101 to rotate relative to the inner ring pipe 1. Since the movement trajectory of the output shaft 702 of the angle adjustment mechanism 7 is arc-shaped, the stroke of the output shaft of the angle expansion and contraction motor 703 is restricted. This stroke is smaller than the radian of the arc-shaped shaft sleeve 701 to ensure that the output shaft of the angle expansion and contraction motor 703 can drive the output shaft 702 to move.

[0054] And because the radian of the arc-shaped shaft sleeve 701 is small, this part can be approximately regarded as a straight line, and the movement principle is similar to that of a linear expansion and contraction mechanism. As Figure 8 shown, from top to bottom are the states of the angle expansion and contraction motor 703 contracting, in the normal state, and expanding, which are also the states of the output shaft 702 contracting, in the normal state, and expanding.

[0055] When the output shaft of the upper angle adjustment mechanism 7 extends, the output shaft of the lower angle adjustment mechanism 7 contracts synchronously. The outer sealing plate 104 is pushed by the upper angle adjustment mechanism 7 to rotate relative to the inner ring pipe 1. When the output shaft of the upper angle adjustment mechanism 7 contracts, the output shaft of the lower angle adjustment mechanism 7 extends synchronously. The outer sealing plate 104 is pushed by the lower angle adjustment mechanism 7 to rotate relative to the inner ring pipe 1.

[0056] The output shaft 702 of the angle adjustment mechanism 7 extends and retracts, driving the outer sealing plate 104 to rotate, thereby driving the rotary nozzle 101 to rotate up and down. Under the action of the connecting rod, the rotary nozzle 101 connected with the adjustment buckle 6 drives the other rotary nozzles 101 to rotate up and down together, achieving the purpose of synchronous adjustment, and the adjustment process is efficient and unified.

[0057] The angle adjustment mechanism 7 can also be a hydraulic cylinder that can output curvilinear motion. The hydraulic cylinder is used to push the outer sealing plate 104 to rotate relative to the inner ring pipe 1.

[0058] In this embodiment, the tail end of the rotary nozzle 101 is rotatably sleeved in the installation pipe 102. The tail end of the rotary nozzle 101 is of a gradually shrinking outlet type. A turbine blade is fixedly installed in the rotary nozzle 101, and the turbine blade is used to drive the rotary nozzle 101 to rotate relative to the installation pipe 102.

[0059] Water flows along the installation pipe 102 and is output to the rotary nozzle 101. Due to the gradually shrinking outlet, the water flow generates a vortex, pushing the turbine blade to rotate. The turbine blade drives the rotary nozzle 101 to rotate relative to the installation pipe 102, and sprays rotating mist to irrigate the apple seedlings.

[0060] In this embodiment, detachable end caps are provided on both sides of the interface 5. The irrigation branch pipe can be connected from one side of the interface 5, and the other side is closed by the detachable end cap, which is convenient for installation. An electromagnetic valve is provided on the tee pipe 4. The electromagnetic valve is a T-shaped valve, which is convenient for remote control. The interface 5 can be connected to the inner ring pipe 1 or the outer ring pipe 2, and the interface 5 can also be connected to or disconnected from the inner ring pipe 1 and the outer ring pipe 2 at the same time.

[0061] In this embodiment, a phase change layer is embedded in the inner ring pipe 1 and the outer ring pipe 2. The phase change layer is made of a paraffin-based phase change material. The phase change layer is used to absorb the environmental heat. When the external environmental temperature is lower than 15°C, the phase change layer releases the stored heat to prevent freezing damage to the root zone.

[0062] In this embodiment, a temperature and humidity sensor and a camera can be set on the device. The environmental temperature and humidity are monitored through the temperature and humidity sensor, and the operation state of the device and the growth environment and state of the apple seedlings are detected through the camera. The micro telescopic motor 302, the servo motor 806, the angle telescopic motor 703 and the electromagnetic valve are all electrically connected to the control system connecting the temperature and humidity sensor and the camera to realize remote monitoring and operation.

[0063] A surrounding apple seedling breeding irrigation method uses the above-mentioned surrounding apple seedling breeding irrigation equipment, and includes the following steps: S1. The staff lays the irrigation pipe in the seedling raising area, installs the surrounding apple seedling breeding irrigation equipment beside each apple seedling, and connects the irrigation pipe with the interface 5 through the irrigation branch pipe; S2. According to the plant height of the apple seedlings, adjust the height of the irrigation mechanism through the lifting mechanism 8, so that the inner ring pipe 1 and the outer ring pipe 2 are moved to a suitable irrigation height. The angle adjustment mechanism 7 drives the rotary sprinkler 101 on the inner ring pipe 1 to rotate relative to the outer ring pipe 2, so that the rotary sprinkler 101 accurately faces the apple seedlings; S3. Open the solenoid valve on the tee 4. The irrigation water in the irrigation pipe enters the inner ring pipe 1 and the outer ring pipe 2 through the tee 4. The rotary sprinkler 101 on the inner ring pipe 1 rotates under the action of water pressure, and at the same time sprays atomized water to irrigate the middle and upper parts of the apple seedlings. The pressure compensating drip head 201 at the bottom of the outer ring pipe 2 irrigates the roots of the apple seedlings; S4. As the apple seedlings grow, adjust the height of the irrigation mechanism through the lifting mechanism 8, adjust the angle of the rotary sprinkler 101 relative to the outer ring pipe 2 through the angle adjustment mechanism 7, and drive the sealing ring 301 to slide through the micro telescopic motor 302 to adjust the inner diameters of the inner ring pipe 1 and the outer ring pipe 2 to adapt to the height and crown diameter of the apple seedlings; S5. In the above steps, liquid fertilizer or insecticide can be added to the irrigation pipe according to the breeding requirements.

[0064] When applying liquid fertilizer for fertilization, adjust the solenoid valve to connect the outer ring pipe 2 with the irrigation pipe. When applying insecticide, adjust the solenoid valve to connect the inner ring pipe 1 with the irrigation pipe.

[0065] When the apple seedlings are in the seedling stage, only irrigate through the outer ring pipe 2. When the apple seedlings enter the adult stage, start to use the inner ring pipe 1 to spray the crown of the saplings.

[0066] During the process of spraying insecticide, only use the inner ring pipe 1 to spray medicine. The lifting mechanism 8 can be started to drive the irrigation mechanism to lift and lower, so as to spray insecticide on different heights of the apple seedling trunk.

[0067] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the present invention. Any simple modification, change and equivalent change made to the above embodiments according to the technical essence of the invention still fall within the protection scope of the technical solution of the present invention.
