Among them, the roots are the core organs for trees to absorb water and nutrients, and the accuracy of water and fertilizer supply directly affects the growth, stress resistance and survival rate of trees.

[0003] Traditional devices mostly provide surface irrigation and fertilization, which prevents water and fertilizer from reaching the effective absorption area of ​​tree roots. Most of the water and fertilizer remain in the shallow soil and are easily evaporated or lost. This not only reduces the absorption effect but also fails to guide tree roots to grow into deeper soil, resulting in shallow root distribution, weak resistance to lodging and adverse conditions, and affecting tree growth and survival rate. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1 to 6This invention provides an integrated root irrigation and fertilization device for trees, including a support 1. Inside the support 1, there are two sets of threaded rods 9 that rotate. On the outside of the two sets of threaded rods 9, there is a support plate 2 that is driven by the threaded rods 9. On the upper surface of the support plate 2, there is a gear B5 that rotates. Inside the gear B5, there is a spiral rod 6 that is hollow. Multiple sets of through holes 7 are opened on the outside of the spiral rod 6. A gear C10 is meshed on one side of the gear B5. A guide tube A11 is provided at one end of the gear C10. Inside the guide tube A11, there is a reciprocating screw 12 that is driven by the gear C10. One end of the support 1 is connected to a liquid storage tank 15. The other end of the liquid storage tank 15 is connected to a proportioning tank 17. One end of the proportioning tank 17 is connected to the inside of the spiral rod 6. Water pump A and water pump B are respectively connected to both sides of the proportioning tank 17.

[0028] A guide tube B23 is installed at the lower end of the bracket 1. A piston rod 22 driven by the support plate 2 slides inside the guide tube B23. One side of the guide tube B23 is connected to the liquid storage tank 15.

[0029] In an optional embodiment, two sets of motors B8 are installed on the upper end of the bracket 1, and two sets of threaded rods 9 are respectively connected to the output ends of the two sets of motors B8, and the two sets of threaded rods 9 are threadedly connected to the support plate 2.

[0030] Before using the device, the staff moves the device to the location where irrigation and fertilization are needed using multiple sets of pulleys at the bottom of the support 1. When using the device, the staff starts two sets of motors B8. After the two sets of motors B8 start, they will drive two sets of threaded rods 9 to rotate synchronously. When the two sets of threaded rods 9 rotate, they will drive the support plate 2 to move downwards gradually.

[0031] In an optional embodiment, a motor A3 is mounted on the upper end of the support plate 2, and a gear A4 is connected to the output end of the motor A3. The gear A4 meshes with the gear B5.

[0032] As described above, when the two sets of motors B8 start, motor A3 will start synchronously. When motor A3 starts, motor A3 will drive gear A4 to rotate. When gear A4 rotates, it will synchronously drive gear B5 to rotate. When gear B5 rotates, gear B5 will synchronously drive the spiral rod 6 to rotate. At this time, as the support plate 2 gradually descends, the spiral rod 6 will gradually extend into the ground.

[0033] In an optional embodiment, the guide tube A11 is connected to the upper surface of the support plate 2, one end of the gear C10 is fixedly connected to the reciprocating screw 12, the reciprocating screw 12 is connected to the piston 13 ball nut pair, one end of the guide tube A11 is connected to the hose A14, and the other end of the hose A14 is connected to the liquid storage tank 15.

[0034] The guide tube A11 has a guide groove inside, and the piston 13 is slidably connected to the guide groove. As described above, when the gear B5 rotates, the gear B5 will synchronously drive the gear C10 to rotate. When the gear C10 rotates, the gear C10 will synchronously drive the reciprocating screw 12 to rotate. When the reciprocating screw 12 rotates, the reciprocating screw 12 will drive the piston 13 to slide back and forth along the guide groove. When the piston 13 moves back and forth, the piston 13 will continuously deliver gas to the inside of the hose A14.

[0035] In an optional embodiment, one end of the liquid storage tank 15 is connected to a hose B16, and the other end of the hose B16 is connected to the inside of the mixing tank 17.

[0036] When the gas enters the hose A14, the hose A14 will transport the gas to the liquid storage tank 15, which contains concentrated fertilizer liquid. When the gas enters the liquid storage tank 15, the gas will squeeze a small amount of fertilizer liquid through the hose B16 into the mixing tank 17.

[0037] In an optional embodiment, a spiral blade 18 is fixedly connected to the inner wall of the mixing tank 17, and a conveying pipe A19 is connected to one side of the mixing tank 17, which is connected to the water pump A.

[0038] As described above, when using the device, water pump A will be turned on simultaneously. When water pump A is turned on, water pump A will deliver water to the mixing tank 17 through the delivery pipe A19. Since the mixing tank 17 is equipped with a spiral vane 18, after the water enters the mixing tank 17, a vortex will be formed inside the mixing tank 17 as guided by the spiral vane 18. At this time, as the fertilizer solution enters the mixing tank 17, the vortex will automatically dilute the fertilizer solution inside the mixing tank 17.

[0039] In an optional embodiment, one end of the mixing tank 17 is connected to a flexible hose C25, the other end of the flexible hose C25 is connected to the inside of the screw rod 6, and the end of the flexible hose C25 away from the mixing tank 17 is rotatably connected to the screw rod 6.

[0040] After the fertilizer solution is diluted inside the mixing tank 17, the diluted fertilizer and water will enter the auger rod 6 through the hose C25. Once inside the auger rod 6, the water and fertilizer will spray outward through multiple sets of through holes 7. Because the amount of water and fertilizer entering the mixing tank 17 is relatively small, in the initial stage of the auger rod 6's descent, when the auger rod 6 is above the tree roots, the amount of water and fertilizer used is minimal, thus preventing the water-fertilizer mixture from being easily lost with surface runoff. This prevents the waste of water and fertilizer, and also prevents the rapid evaporation of water from causing fertilizer accumulation in the surface soil, which would increase soil osmotic pressure and lead to dehydration and necrosis of shallow root cells. By precisely controlling the amount of water and fertilizer delivered, and spraying a low amount at the beginning of the descent of the spiral rod 6, water and fertilizer are prevented from being lost with surface runoff, significantly improving water and fertilizer utilization, reducing resource waste, preventing fertilizer accumulation in the surface soil, preventing dehydration and necrosis of shallow root cells of trees caused by increased soil osmotic pressure, protecting the health of tree roots, and improving the ecological safety of irrigation and fertilization.

[0041] In an optional embodiment, a sensor 21 is mounted on one side of the bracket 1, and the sensor 21 is electrically connected to the water pump B.

[0042] As the support plate 2 continues to descend, when the support plate 2 moves to be flush with the sensor 21, the sensor 21 will transmit the monitored signal to the water pump B, thereby causing the water pump B to start.

[0043] In an optional embodiment, the other side of the mixing tank 17 is connected to a conveying pipe B20, and the other end of the conveying pipe B20 is connected to a water pump B.

[0044] When the support plate 2 moves to be flush with the water pump B, it means that the screw rod 6 is gradually approaching the root system of the tree. At this time, the water pump B will deliver water into the mixing tank 17 through the delivery pipe B20, thereby increasing the irrigation amount.

[0045] In an optional embodiment, a connecting pipe 24 is connected to one side of the guide pipe B23, and the other end of the connecting pipe 24 is connected to the inside of the liquid storage tank 15. A one-way valve is provided at the connection between the connecting pipe 24 and the liquid storage tank 15, and one end of the piston rod 22 is magnetically connected to the support plate 2.

[0046] When the support plate 2 is flush with the sensor 21, the lower end of the support plate 2 will contact the piston rod 22. As the support plate 2 continues to descend, it will compress the piston rod 22 and retract it into the guide tube B23. When the piston rod 22 retracts into the guide tube B23, it will compress gas through the connecting pipe 24 and the one-way valve into the liquid storage tank 15. After the gas enters the liquid storage tank 15, it will increase the amount of fertilizer solution entering the mixing tank 17. Therefore, when the spiral rod 6 extends to the root system of the tree, the device will automatically increase the irrigation of water and fertilizer. The increased water and fertilizer volume allows for better application of water and fertilizer to the tree root system. Simultaneously, the increased water and fertilizer in the deep irrigation layer can induce the tree roots to grow deeper. By increasing the water and fertilizer volume synchronously with the spiral rod 6, a large flow of water and fertilizer can be directly applied to the tree root zone, increasing water and fertilizer absorption efficiency, significantly improving water and fertilizer utilization, reducing shallow waste, and ensuring sufficient deep water and fertilizer supply. This guides the tree roots to actively extend into the water and fertilizer-rich deep soil, enhancing the tree's soil-fixing ability and drought and barrenness tolerance, improving the tree's resistance to lodging and stress, and enhancing long-term growth and survival rate.

[0047] When the support plate 2 rises and resets, the support plate 2 will synchronously drive the piston rod 22 to rise and reset through magnetic attraction.

[0048] Working principle: Before using the device, the staff moves the device to the location where irrigation and fertilization are needed by using multiple sets of pulleys at the lower end of the support 1. When using the device, the staff starts two sets of motors B8. After the two sets of motors B8 start, they will drive the two sets of threaded rods 9 to rotate synchronously. When the two sets of threaded rods 9 rotate, they will drive the support plate 2 to move downward gradually.

[0049] When the two sets of motors B8 start, motor A3 will start synchronously. When motor A3 starts, motor A3 will drive gear A4 to rotate. When gear A4 rotates, it will synchronously drive gear B5 to rotate. When gear B5 rotates, gear B5 will synchronously drive the screw rod 6 to rotate. At this time, as the support plate 2 gradually descends, the screw rod 6 will gradually extend into the ground.

[0050] When gear B5 rotates, gear B5 will synchronously drive gear C10 to rotate. When gear C10 rotates, gear C10 will synchronously drive reciprocating screw 12 to rotate. When reciprocating screw 12 rotates, reciprocating screw 12 will drive piston 13 to slide back and forth along the guide groove. When piston 13 moves back and forth, piston 13 will continuously deliver gas into hose A14. When the gas enters hose A14, hose A14 will deliver the gas to storage tank 15. Storage tank 15 stores concentrated fertilizer liquid. When the gas enters storage tank 15, the gas will squeeze a small amount of fertilizer liquid through hose B16 into proportioning tank 17.

[0051] When using the device, water pump A will be turned on simultaneously. When water pump A is turned on, water pump A will deliver water to the mixing tank 17 through the delivery pipe A19. Because the mixing tank 17 is equipped with a spiral blade 18, after the water enters the mixing tank 17, a vortex will be formed inside the mixing tank 17 as guided by the spiral blade 18. At this time, as the fertilizer solution enters the mixing tank 17, the vortex will automatically dilute the fertilizer solution inside the mixing tank 17. After the fertilizer solution is diluted inside the mixing tank 17, the diluted fertilizer and water will enter the spiral rod 6 through the hose C25. After the water and fertilizer enter the spiral rod 6, the water and fertilizer will be sprayed out through multiple sets of through holes 7. Because the amount of water and fertilizer entering the mixing tank 17 is relatively small, in the initial stage of the spiral rod 6 descending, when the spiral rod 6 is above the tree roots, the amount of water and fertilizer used is relatively small.

[0052] As the support plate 2 continues to descend, when the support plate 2 moves to be level with the sensor 21, the sensor 21 will transmit the monitored signal to the water pump B, thereby starting the water pump B. When the support plate 2 moves to be level with the water pump B, it means that the screw rod 6 is gradually approaching the root system of the tree. At this time, the water pump B will deliver water into the mixing tank 17 through the delivery pipe B20, thereby increasing the irrigation amount of water.

[0053] When the support plate 2 is flush with the sensor 21, the lower end of the support plate 2 will contact the piston rod 22. As the support plate 2 continues to descend, it will squeeze the piston rod 22 to retract into the guide tube B23. When the piston rod 22 retracts into the guide tube B23, it will squeeze the gas through the connecting pipe 24 and the one-way valve into the liquid storage tank 15. After the gas enters the liquid storage tank 15, it will increase the amount of fertilizer solution entering the mixing tank 17. Therefore, when the spiral rod 6 extends to the root system of the tree, the device will automatically increase the amount of water and fertilizer irrigation.
