Description
Technical Field
[0001] This invention belongs to the field of landscape management technology, and in particular relates to a root irrigation device for large-sized trees and shrubs in landscapes. Background Technology
[0002] In landscaping maintenance and the cultivation of large seedlings, applying pesticides and fertilizers to large-sized trees and shrubs to prevent pests and diseases and supplement nutrients is an important and arduous task. Currently, common methods of pesticide and fertilizer application mainly include manual ground spraying, foliar spraying with spray guns, or simple shallow root irrigation.
[0003] These traditional methods have many limitations: First, the fertilizer and pesticides mainly remain on the soil surface or adhere to branches and leaves, making it difficult to accurately deliver them to the deep soil areas where the tree's root system is concentrated, resulting in low utilization and slow effectiveness. Secondly, large-scale manual operation is inefficient, labor-intensive, and difficult to control the amount and uniformity of application. Furthermore, for mature trees with large canopies and extensive root systems, it is difficult to achieve uniform application of pesticides and fertilizers around the root zone, which can easily lead to blind spots in maintenance. In addition, frequent manual labor and vehicle traffic can easily damage the soil structure around the tree basin and compact the root system.
[0004] Therefore, the field of garden maintenance urgently needs a specialized device that can achieve precise, efficient, deep, and uniform application of pesticides and fertilizers, and can adapt to different tree sizes and site terrain conditions.
[0005] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Summary of the Invention
[0006] To address the aforementioned problems, the present invention aims to provide a root irrigation device for large-sized trees and shrubs in gardens. This device utilizes an openable and closable annular guide rail structure composed of a first and second arc-shaped guide rail, and a guide rail slider driven by a first motor and moving along a gear ring. This allows for convenient wrapping around the tree trunk. The insertion tube mounted on the slider can flexibly adjust its insertion angle and depth under the drive of a second motor and a first cylinder, directly and accurately injecting the fertilizer solution into the deep soil layers of the tree's main root distribution area. This multi-point, annular, and deep irrigation method greatly improves the utilization rate and effectiveness of the fertilizer, avoiding the waste and loss associated with surface application.
[0007] To achieve the above objectives, the present invention proposes a fertilizer and pesticide root irrigation device suitable for large-sized trees and shrubs in gardens.

[0011] Furthermore, an arc-shaped rack is fixed below both the first and second arc-shaped guide rails, and the two arc-shaped racks are combined to form a gear ring. A connecting plate is fixed on one side of the guide rail slider, and a first motor is fixed below the connecting plate. A gear that meshes with the gear ring is fixed on the output shaft of the first motor.
[0012] Furthermore, the clamping side of the clamping block is provided with a buffer layer.
[0013] Furthermore, the water outlet of the water tank is located near its bottom, and the water pipe assembly includes a first flexible hose connected to the water outlet of the water tank, a blind pipe connected to the first flexible hose, the blind pipe being a flexible hose, and a second flexible hose connected between the insertion pipe and the blind pipe.
[0014] Furthermore, a partition is fixed inside the insertion tube, an electric telescopic rod is fixed inside the insertion tube, a connecting rod is fixed on the output shaft of the electric telescopic rod, the connecting rod passes through the partition and a sealing ball for sealing the liquid outlet of the insertion tube is fixed thereon, and a sealing ring is provided between the connecting rod and the partition.
[0015] Furthermore, the fertilizer and pesticide root irrigation device also includes a clamping assembly for controlling the movement of the fertilizer and pesticide root irrigation device.
[0016] Furthermore, the clamping assembly includes symmetrically distributed clamping arms, with two clamping arms respectively fixed to both sides of the vehicle frame.
[0017] Furthermore, the clamping arm includes a drive box fixed to the frame, a third motor fixed inside the drive box, and a U-shaped connecting plate fixed to the drive box on the side away from the frame. A second cylinder is rotatably mounted on the U-shaped connecting plate, and a fourth motor for driving the second cylinder to rotate is fixed on the U-shaped connecting plate.

[0022] 3. The invented fertilizer and pesticide root irrigation equipment integrates multiple motors, cylinders, and electric telescopic rods, realizing automated or semi-automated operation of the ring guide rail opening and closing, circumferential positioning, radial angle adjustment, insertion depth control, and liquid outlet opening and closing. It greatly reduces the labor intensity of operators, allowing one person to complete multi-point irrigation around the tree trunk, and the irrigation points, angles, depths, and fertilizer and pesticide output are all controllable, with a high degree of standardization in the operation.
[0023] 4. The device's insert tube features a sealing ball mechanism controlled by an electrically operated telescopic rod, which seals the tube opening during soil insertion, effectively preventing soil blockage of the outlet and ensuring smooth irrigation of the pesticide and fertilizer. The water pipe assembly uses flexible hoses and blind pipes, providing ample pipeline redundancy for the mobile insert tube and ensuring continuous pesticide and fertilizer delivery. The device has a compact overall structure, with all functions integrated into a transport vehicle, making it easy to move and relocate. It is ideal for mobile maintenance of scattered large trees and shrubs in garden environments. Attached Figure Description

[0042] Working principle: I. Equipment movement and positioning (clamping component 5 in operation); Mobility: It can be pushed by manpower or moved on its own in gardens with earthen surfaces.
[0043] The third motor 52 is started to adjust the second cylinder 54 to be horizontal. The fourth motor 55 is started to adjust the position of the second cylinder 54. The sixth motor 57 is started to adjust the insertion rod 511 to be vertical and downward. The fourth cylinder 510 is started to insert the insertion rod 511 into the ground. By controlling the extension and retraction of the second cylinder 54, the movement of the transport vehicle 1 can be controlled. Then, the insertion rod 511 is pulled out of the ground and the second cylinder 54 is reset to start the next movement operation until the equipment is moved to the vicinity of the target tree.
[0044] Trees can also be clamped by clamping plate 59, and the movement of transport vehicle 1 can be controlled by activating the second cylinder 54.
[0045] II. Root irrigation system surrounding and positioning; The third motor 52 and the fourth motor 55 work together to control the insertion rod 511 to be inserted into the second arc-shaped guide rail 32. Activating the fourth motor 55 controls the opening and closing of the first arc-shaped guide rail 31 and the second arc-shaped guide rail 32. After opening the second arc-shaped guide rail 32, the transport trolley is moved so that both clamping plates 59 correspond to the first arc-shaped guide rail 31. Then, the third cylinder 58 is activated to control the two clamping plates 59 to move closer together to clamp the first arc-shaped guide rail 31. By controlling one of the second cylinders 54 to extend and the other to shorten, the opening position of the first arc-shaped guide rail 31 is adjusted, thus opening the first arc-shaped guide rail 31. The opening corresponds to the target tree. By extending the second cylinder 54, the first arc-shaped guide rail 31 is controlled to surround the tree trunk. By activating the sixth cylinder 311, the clamping block 312 is controlled to clamp the tree trunk, thus fixing the first arc-shaped guide rail 31. Then, the transport vehicle 1 is moved, and the first arc-shaped guide rail 31 and the second arc-shaped guide rail 32 are controlled to merge by the insertion rod 511. The first arc-shaped guide rail 31 and the second arc-shaped guide rail 32 are clamped by two clamping plates 59 respectively to fix the ring guide rail (if the position of the transport vehicle 1 or the position of the tree makes it inconvenient for the insertion rod 511 to control the opening and closing of the first arc-shaped guide rail 31 and the second arc-shaped guide rail 32, manual intervention is required).
[0046] III. Multi-point insertion and root drenching operations; Circumferential positioning: Start the first motor 37 on the guide rail slider 33, drive the gear 38 to roll along the gear ring 35, and drive the guide rail slider 33 (and the insertion tube 310) to move along the annular guide rail to the predetermined root dredging position.
[0047] Angle adjustment: The second motor 34 drives the first cylinder 39 and the insertion tube 310 to swing in the radial plane to adjust the insertion angle to adapt to different root zone positions.
[0048] Soil insertion: The first cylinder 39 extends and pushes the insertion tube 310 downward into the soil of the tree root zone. During the insertion process, the sealing ball 3104 blocks the liquid outlet of the insertion tube 310 to prevent the liquid outlet from being blocked.
[0049] Injecting fertilizer and pesticide: The liquid fertilizer in the water tank is transported to the insertion tube 310 through the first hose 41, the blind tube 42 and the second hose 43; When inserted into the tube 310, the electric telescopic rod 3102 retracts, which drives the sealing ball 3104 to move upward through the connecting rod 3103, opening the liquid outlet. Under the influence of gravity or the pressure of water tank 2, the fertilizer and pesticide are injected into the deep soil layer through the lower end of the insertion tube 310, with a root irrigation depth of 400-500mm. A high-pressure pump can be installed at the outlet of water tank 2 for pressurized root irrigation.
[0050] Liquid discharge control: After the root irrigation volume reaches the standard (maximum diameter 1 meter), the electric telescopic rod 3102 extends, pushes the sealing ball 3104 down to re-close the liquid outlet, and stops the injection.
[0051] Repeated point shifting: The first cylinder 39 retracts to pull the insertion tube 310 away from the soil, and the first motor 37 drives the track slider 33 to move to the next root irrigation point, realizing ring-shaped multi-point root irrigation.
[0052] IV. Completion of Operations and Evacuation; After the root irrigation is completed, all insertion tubes 310 are retracted and moved away from the trunk.
[0053] Clamping assembly 5 operates in reverse order: removing the equipment from the tree and transferring it to the next work point.
