Description
Technical Field
[0001] This invention relates to the field of fruit tree planting and fertilization technology, specifically to an intelligent drip irrigation device for fruit tree planting. Background Technology
[0002] As my country's fruit tree planting industry undergoes a profound transformation towards large-scale, standardized, and intelligent operations, integrated water and fertilizer management has become a core element determining fruit yield, fruit quality, and overall planting benefits. Drip irrigation technology can precisely deliver the water, mineral nutrients, and growth regulators needed for fruit tree growth to the root zone. Compared to traditional methods such as flood irrigation, fertigation, and hole application, it can increase water and fertilizer utilization by over 60%, while significantly reducing resource waste and soil and groundwater pollution. It has been widely applied in the standardized planting of various economic fruit trees such as apples, citrus, cherries, and pears.
[0003] Currently, drip irrigation for fruit trees mainly involves laying main pipes, branch pipes, and surface / underground capillary pipes throughout the orchard, combined with fixed drippers to achieve targeted drip irrigation. The core problems with this type of system are: First, the initial installation cost is extremely high, especially in orchards with complex terrain such as mountains and hills, where pipeline construction is difficult and time-consuming. The initial infrastructure investment is a very high percentage for large-scale orchards, making it unaffordable for small and medium-sized growers. Second, the adaptability is extremely poor. The location of the fixed drippers cannot be adjusted according to changes in the age, variety, and growth cycle of the fruit trees, and it cannot accommodate the vastly different root spreads of young and mature trees, thus failing to achieve precise fertilization. Furthermore, in some orchards, fruit trees have different growth cycles, and existing drip irrigation networks can only use the same nutrient solution for drip irrigation, unable to provide precise ratios for individual tree species, thus limiting its applicability. Summary of the Invention
[0004] The purpose of this invention is to provide an intelligent drip irrigation device for nutrient solution in fruit tree planting in order to solve the above problems.
[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution: An intelligent drip irrigation device for nutrient solution in fruit tree planting includes an intelligent mobile trolley. The top of the intelligent mobile trolley is inclinedly provided with a fertilizer applicator mounting component. A bracket is mounted on the top of the fertilizer applicator mounting component. A rotary drive switching motor is fixedly mounted on the top of the bracket. A rotary switching bracket is fixedly mounted on the top of the output end of the rotary drive switching motor.

[0008] Furthermore, guide cylinders are welded to both sides of the fertilizer applicator, and fixed rods are inserted into the inside of the guide cylinders. A tapered component is provided on the outside of the fixed rods, and a guide groove is opened on the outside of the guide cylinders. The tapered component can slide along the guide groove. The guide groove consists of a vertical guide groove, a horizontal guide groove, and a snap-fit guide groove. The horizontal guide groove is located at the bottom end of the vertical guide groove and is close to the fertilizer applicator mounting assembly. A swing motor is fixedly installed on the inside of the clamping rod, and a swing arm is installed at the output end of the swing motor. The swing arm is located on the outside of the clamping rod and can contact the tapered component.
[0009] Furthermore, a clamping spring is provided on the inner side of the upper half of the vertical guide groove.
[0010] Furthermore, the outer side of the rotating switching bracket is provided with several rectangular mounting frames, and an electromagnetic connector is provided inside the rectangular mounting frames. The fertilizer rack is provided with a connector that can be inserted into the rectangular mounting frames. The top of the connector has a connection port, and the electromagnetic connector can be inserted into the connection port.
[0011] Furthermore, the fertilizer tank is rotatably installed in the fertilizer frame, and a guide post is provided on the outside of the fertilizer tank. The guide post is located above the rotation center of the fertilizer frame. An arc-shaped guide groove is opened inside the fertilizer frame. The center of the arc of the guide groove coincides with the rotation center of the fertilizer frame. The guide post passes through the arc-shaped guide groove. A tension spring is provided between the guide post and the fertilizer frame. The tension spring is used to drive the guide post to slide upward along the arc-shaped guide groove. A counterweight piston is slidably connected inside the fertilizer tank. A pressure spring is provided between the counterweight piston and the top of the fertilizer tank. A one-way injection port is provided at the bottom of the fertilizer tank.
[0012] Furthermore, the bottom of the fertilizer tank is provided with a socket, the inner wall of the socket has a sliding hole, and a locking block is slidably connected inside the sliding hole. The side of the locking block away from the fertilizer tank has an inclined surface, and a retaining spring is provided between the locking block and the inner wall of the sliding hole.

[0013] Furthermore, an annular groove is provided on the outer side of the top ring, and a positioning protrusion is provided on the inner wall of the socket.
[0014] The beneficial effects of this invention are as follows: This invention employs a modular fertilizer applicator system. Multiple modular fertilizer applicators are installed on an intelligent mobile trolley, with each modular applicator corresponding to a fruit tree. Through intelligent mobile trolley path planning and rotation angle matching of the rotating switching bracket, and the configuration of the fertilizer applicator installation components, the corresponding modular fertilizer applicator can be fixed next to the corresponding tree and inserted obliquely into the root zone of the fruit tree for nutrient solution drip irrigation and fertilization. This fundamentally eliminates the problem of cross-contamination of nutrient solutions, avoids the risk of fertilizer damage caused by mixed formulas, and greatly simplifies the operation process of multi-formula operations. It can accurately adapt to the nutritional needs of fruit trees at different stages such as flowering, fruit expansion, and post-harvest recovery, achieving refined nutrient management and effectively improving fruit tree yield and fruit quality.
[0015] This invention features a separate design for the fertilizer drip irrigation rod and the fertilizer tank. After the fertilizer drip irrigation rod is inserted obliquely into the root zone, the fertilizer tank can swing freely. Through the arrangement of a tension spring and a counterweight spring, as the amount of fertilizer inside the fertilizer tank decreases, the internal pressure of the fertilizer tank decreases. At this time, the tension spring causes the fertilizer tank to swing upward, and the gravity of the counterweight piston increases the internal pressure of the fertilizer tank, thereby making the fertilizer pressure more stable and improving the fertilization effect.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0019] Example 1, as Figures 1-7 As shown, an intelligent drip irrigation device for fruit tree planting includes an intelligent mobile trolley 1. The top of the intelligent mobile trolley 1 is inclinedly provided with a fertilizer applicator mounting component 2. The top of the fertilizer applicator mounting component 2 is supported by a bracket 3. A rotary drive switching motor 4 is fixedly installed on the top of the bracket 3. A rotary switching bracket 5 is fixedly installed on the top of the output end of the rotary drive switching motor 4. Several modular fertilizer applicators 6 are installed in a ring on the outer side of the rotary switching bracket 5. The modular fertilizer applicator 6 consists of a fertilizer frame 61, a fertilizer tank 62, and a fertilizer drip irrigation rod 63. The fertilizer frame 61 is detachably mounted on the rotating switching bracket 5. The fertilizer applicator mounting component 2 can fix the fertilizer frame 61 in the soil. The fertilizer tank 62 is installed at an angle on the fertilizer frame 61. The fertilizer drip irrigation rod 63 is set on the fertilizer tank 62. The fertilizer applicator mounting component 2 can make the fertilizer drip irrigation rod 63 obliquely inserted into the root of the fruit tree.
[0020] The fertilizer applicator installation assembly 2 includes an insertion linear slide rail module 21 installed on the intelligent mobile trolley 1. The insertion linear slide rail module 21 is set at an angle of 45°. An installation frame 22 is installed on the insertion linear slide rail module 21. A bidirectional linear slide rail module 23 is fixedly installed on the installation frame 22. Two sets of clamping rods 24 are provided on the bidirectional linear slide rail module 23. The two sets of clamping rods 24 can clamp the fertilizer frame 61 from the inside.
[0021] Both sides of the fertilizer applicator 61 are welded with guide cylinders 65. A fixed rod 66 is inserted into the inside of the guide cylinder 65. A tapered part 661 is provided on the outside of the fixed rod 66. A guide groove is opened on the outside of the guide cylinder 65. The tapered part 661 can slide along the guide groove. The guide groove is composed of a vertical guide groove 651, a horizontal guide groove 652 and a snap-fit guide groove 653. The horizontal guide groove 652 is located at the bottom end of the vertical guide groove 651 and is close to the fertilizer applicator mounting assembly 2. A swing motor 26 is fixedly installed on the inside of the clamping rod 24. A swing rod 27 is installed at the output end of the swing motor 26. The swing rod 27 is located on the outside of the clamping rod 24 and can contact the tapered part 661.
[0022] A clamping spring 654 is provided on the inner side of the upper half of the vertical guide groove 651.
[0023] Designated fertilization logic: The intelligent mobile trolley 1 is equipped with a track drive, a mobile power supply and a remote intelligent control system. One fertilizer tank 62 is matched with one fruit tree. The fertilizer solution with a specified ratio is pre-injected into the tank. The fertilizer tank 62 corresponding to the first fruit tree on the trolley's movement path is number one. The number one tank is installed at position one of the rotating switching bracket 5. In this way, the modular fertilizer applicators 6 can be installed sequentially on the path by simply controlling the rotating switching bracket 5 to rotate at a specified angle.
[0024] Fertilization steps: The intelligent mobile trolley 1 moves to the pre-planned position on the fruit tree, then the rotating drive switching motor 4 drives the rotating switching bracket 5, which in turn drives the corresponding modular fertilizer applicator 6 to rotate to the fertilization position. Then, the linear slide rail module 21 is inserted, which drives the bidirectional linear slide rail module 23 to move towards the fertilizer rack 61. The bidirectional linear slide rail module 23 drives the clamping rod 24 into the inside of the fertilizer rack 61. Then, the bidirectional linear slide rail module 23 moves the two sets of clamping rods 24 away from each other, clamping the fertilizer rack 61 from the inside. At this time, the fertilizer rack 61 separates from the rotating switching bracket 5. The inserted linear slide rail module 21 drives the fertilizer rack 61 to move obliquely downwards towards the fruit tree. The fertilizer rack 61 drives the fertilizer tank 62 and the fertilizer drip irrigation rod 63 to be inserted at a 45° angle into the root of the fruit tree for drip irrigation fertilization.
[0025] After insertion, the swing motor 26 is powered on, and the swing motor 26 drives the swing rod 27 to swing downward. The fixed insertion rod 66 is initially stored in the guide tube 65, and the conical part 661 is engaged in the clamping spring 654. The fixed insertion rod 66 will not fall off automatically. Through this design, the fixed insertion rod 66 will not affect the insertion of the fertilizer drip irrigation insertion rod 63 into the root of the fruit tree. When the swing arm 27 swings to the position of the conical part 661, the swing arm 27 pushes the conical part 661 to slide downward along the vertical guide groove 651, and the fixed insertion rod 66 is inserted vertically downward into the soil. When the conical part 661 descends to the position of the horizontal guide groove 652, the swing end of the swing arm 27 is lower than the center of rotation. When the swing arm 27 continues to swing, it applies a force to the conical part 661 in the direction of the trolley through the conical surface of the conical part 661. At this time, the conical part 661 slides to the deepest point along the horizontal guide groove 652. Then, the bidirectional linear slide rail module 23 is controlled to bring the two sets of clamping rods 24 closer to each other, and the fertilizer frame 61 is released. The fertilizer frame 61 descends under the action of gravity. The fertilizer frame 61 drives the guide cylinder 65 to descend relative to the fixed insertion rod 66. The conical part 661 enters the snap-fit guide groove 653. At this time, the guide cylinder 65 and the fixed insertion rod 66 are fixed in position, and the fertilizer frame 61 is inserted and fixed. The trolley moves to the position of the next fruit tree.
[0026] Example 2, based on the above examples, also includes a positioning block 25 on the outer side of the clamping rod 24, a positioning port 613 on the fertilizer rack 61, an intelligent mobile trolley 1 with its own visual recognition system, an electric telescopic rod at the bottom of the inserted linear slide rail module 21, the visual recognition of the position of the positioning port 613, and the electric telescopic rod adjusting the positioning block 25 to the same height.
[0027] Using the visual recognition system and the position of the positioning port 613, after drip irrigation is completed, the electric telescopic rod adjusts the positioning block 25 to the corresponding height and matches the positioning port 613. The modular fertilizer applicator 6 can then be pulled out of the soil as a whole. After being taken out of the orchard, it is manually cleaned and reset.
[0028] In embodiment three, based on the above embodiments, a plurality of rectangular mounting frames 51 are arranged in a ring around the outer side of the rotating switching bracket 5. An electromagnetic connector 52 is arranged inside the rectangular mounting frame 51. A connector 614 is arranged on the fertilizer rack 61. The connector 614 can be inserted into the rectangular mounting frame 51. A connection port is opened on the top of the connector 614, and the electromagnetic connector 52 can be inserted into the connection port.
[0029] The electromagnetic connector 52 is a conventional electromagnet, spring and plug structure. When energized, it attracts the plug away from the connection port to release it. When de-energized, the spring pushes the plug into the connection port to achieve connection.
[0030] Example 4, based on the above examples, further includes a fertilizer tank 62 rotatably mounted in a fertilizer frame 61. A guide post 621 is provided on the outer side of the fertilizer tank 62, located above the rotation center of the fertilizer frame 61. An arc-shaped guide groove 611 is provided inside the fertilizer frame 61, with the arc center of the guide groove 611 coinciding with the rotation center of the fertilizer frame 61. The guide post 621 passes through the arc-shaped guide groove 611. A tension spring 612 is provided between the guide post 621 and the fertilizer frame 61, which drives the guide post 621 to slide upward along the arc-shaped guide groove 611. A counterweight piston 622 is slidably connected inside the fertilizer tank 62. A pressure spring 623 is provided between the counterweight piston 622 and the top of the fertilizer tank 62. A one-way injection port 624 is provided at the bottom of the fertilizer tank 62.
[0031] A socket 67 is located at the bottom of the fertilizer tank 62. A sliding hole is formed on the inner wall of the socket 67, and a locking block 671 is slidably connected inside the sliding hole. An inclined surface is provided on the side of the locking block 671 away from the fertilizer tank 62. A retaining spring 672 is provided between the locking block 671 and the inner wall of the sliding hole. A top ring 673 is slidably connected inside the socket 67, and the top ring 673 is connected to the locking block 671 via a transmission rope 674. The friction between the top ring 673 and the socket 67 is greater than the elastic force of the retaining spring 672, enabling drip irrigation of fertilizer. The insertion rod 63 has a post 631 at one end near the fertilizer tank 62. The post 631 can be inserted into the socket 67. A slot 632 is formed on the outer side of the post 631, and a locking block 671 can be inserted into the slot 632. The length of the slot 632 is greater than the thickness of the locking block 671. The fertilizer drip irrigation insertion rod 63 is connected to the fertilizer tank 62 through a connecting hose 64. When the post 631 is fully inserted into the socket 67, the connecting hose 64 is folded and compressed into the socket 67 and is not conductive. An annular groove is formed on the outer side of the top ring 673, and a positioning protrusion 675 is provided on the inner wall of the socket 67.
[0032] Before the fertilizer drip irrigation rod 63 is inserted into the soil, the rod 631 is fully inserted into the socket 67, the connecting hose 64 is folded and squeezed into the socket 67 and is not conductive, ensuring that the fertilizer tank 62 will not automatically drain the liquid, and the locking block 671 is inserted into the locking groove 632. The fertilizer drip irrigation rod 63 and the fertilizer tank 62 are integrated and self-sealing.
[0033] Therefore, during the insertion process, the fertilizer tank 62 and the fertilizer drip irrigation rod 63 are first inserted into the soil. As the resistance of the fertilizer drip irrigation rod 63 gradually increases, it pushes the top ring 673 to move into the socket 67. The top ring 673 drives the locking block 671 to retract away from the slot 632 through the transmission rope 674 until the positioning protrusion 675 is engaged in the annular groove, thus achieving the positioning and fixing of the top ring 673. (It should be noted that the length of the slot 632 is greater than the thickness of the locking block 671. Therefore, when the locking block 671 is inserted into the slot 632, the fertilizer drip irrigation rod 63 can also move into the socket 67, but cannot detach from the socket 67.) Then, the linear slide rail module 21 is inserted to move the fertilizer tank 62 away from the fertilizer drip irrigation rod 63. The connecting hose 64 is stretched and unfolded. At this time, the pipeline is connected. Under the pressure of the pressure spring 623, the nutrient solution is input to the roots of the fruit tree through the connecting hose 64 and the fertilizer drip irrigation rod 63.
[0034] The fertilizer applicator 61 is then fixed in the soil. Since the fertilizer applicator 61 and the fertilizer drip irrigation rod 63 are fixed in the soil separately, they do not interfere with each other. As the liquid inside the fertilizer tank 62 decreases, the internal pressure of the fertilizer tank 62 decreases. At this time, the tension spring 612 drives the upper part of the fertilizer tank 62 to swing upward, increasing its tilt angle. The tilt angle of the counterweight piston 622 also increases, and the pressure of the counterweight piston 622 on the liquid increases accordingly, increasing the internal pressure of the fertilizer tank 62. Through the pressure self-balancing method, the fertilizer pressure tends to be stable throughout the process with little change, resulting in better fertilization effect.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
