A delivery pipe is provided at the input end of the water pump, and a rotary joint is provided at the output end. A gear plate is provided on the top of the rotary joint. This invention allows users to inject an appropriate amount of water into the water tank through the water inlet. An external controller starts the water pump, which delivers the water through the delivery pipe to the inner cavity of the rotary joint, then into the inner cavity of a pressurizing device. After being pressurized by the pressurizing device, the water is injected into the inner cavity of the spray nozzle and sprayed out through the nozzle. This solves the problem of existing irrigation devices lacking all-around irrigation functionality, which easily leads to irrigation blind spots.

[0013] Compared with the prior art, this utility model provides a tree all-round irrigation device, which has the following beneficial effects:

[0014] In the technical solution disclosed in this utility model, the propeller rod in the rotating component inside the transfer pipe is matched with the spiral blade structure of the water flow direction. The irrigation water flow impacts the propeller rod to generate rotational power, which drives the spray head to rotate automatically through the connecting rod and bearing transmission, so as to achieve 360-degree irrigation coverage.

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Figures 1-4 In one embodiment of this utility model, a tree all-round irrigation device includes a transfer pipe 1, one end of which is fixedly connected to a water inlet pipe 2, a rotating component 3 is fixedly connected inside the transfer pipe 1, a spray head 4 is fixedly connected to the top of the rotating component 3, a connecting pipe 5 is fixedly connected to the bottom surface of the spray head 4, a sealing ring 6 is sleeved inside the connecting pipe 5, the sealing ring 6 is rotatably connected to the top of the transfer pipe 1, and an installation component 7 is fixedly connected to the other end of the transfer pipe 1.

[0024] The specific problem addressed in this embodiment is that relying on a motor for rotation requires an external power supply, limiting its application scenarios and posing a certain risk of failure when used with the electrical structure. This invention utilizes a propeller shaft 34 within the rotating assembly 3 of the adapter pipe 1, with its helical blades matching the water flow direction. The irrigation water flow impacts the propeller shaft 34, generating rotational power, which, via the connecting rod 33 and bearing 32, drives the spray head 4 to rotate automatically, achieving 360-degree irrigation coverage. Compared to the motor-driven method in the prior art, this method requires no external power supply and offers higher structural reliability.

[0025] The rotating assembly 3 includes a bracket 31 fixedly connected to the inner wall of the transfer pipe 1. A bearing 32 is fixedly connected to the surface of the bracket 31. A connecting rod 33 is sleeved inside the bearing 32. A propeller rod 34 is fixedly connected to the top of the connecting rod 33. The top of the propeller rod 34 is fixedly connected to the inner top wall of the spray head 4 through a support rod 35. In this specific embodiment, the propeller rod 34 includes at least three helical blades. The inclination direction of the helical blades matches the water flow direction inside the transfer pipe 1. The rotating assembly 3 is based on a bracket 31 fixed to the inner wall of the transfer pipe 1. The bracket 31 is welded or bolted to a bearing 32. The inner ring of the bearing 32 is fitted with a vertically arranged connecting rod 33. The top of the connecting rod 33 is fixed to a propeller rod 34 by a flange or threaded connection. The propeller rod 34 consists of three helical blades at an angle of 30°-45° to the water flow direction in the transfer pipe 1. Three support rods 35 symmetrically distributed at 120° extend from the top of the propeller rod 34. The top of the support rods 35 are rigidly connected to the inner top wall of the spray head 4 by welding, so that when the water flow drives the propeller rod 34 to rotate, the support rods 35 drive the spray head 4 to rotate synchronously.

[0026] In this specific embodiment, the installation component 7 includes a collar 71 fixedly connected to one end of the adapter pipe 1, a base plate 72 fixedly connected to the bottom surface of the collar 71, and insert rods 73 fixedly connected to the bottom surface of the base plate 72 in a rectangular array.

[0027] The mounting assembly 7 includes a collar 71 that is welded to the outer wall of the end of the adapter pipe 1. A circular base plate 72 with a diameter larger than the collar 71 is welded to the bottom of the collar 71. Four tapered inserts 73 with a length of 20-30cm are integrally formed on the bottom surface of the base plate 72 by stamping. The four inserts 73 are distributed in a rectangular array symmetrically arranged around the center of the base plate 72. The distance between adjacent inserts 73 is 1 / 3 of the diameter of the base plate 72. The surface of the inserts 73 is provided with anti-slip texture to enhance the adhesion to the soil. The bottom end of the inserts 73 is processed into an acute-angled tip so that it can be inserted into the ground to complete the fixed installation of the irrigation device.

[0028] In this specific embodiment, a stainless steel filter screen with a pore size of 1-2mm is fixedly installed on the inner wall of the connection between the water inlet pipe 2 and the adapter pipe 1 via a slot or flange. The filter screen has a circular structure and a rubber sealing ring on the edge. Its installation direction is perpendicular to the axis of the water inlet pipe 2. The filter screen is located 5-10cm upstream of the water inlet of the adapter pipe 1. When the water flows into the adapter pipe 1 after passing through the filter screen, impurities such as mud, sand, and leaves with a diameter greater than 2mm are intercepted. Its beneficial effects are reflected in the following: the filter screen prevents impurities from entering the interior of the adapter pipe 1 through physical interception, prevents clogging of the blade gap of the propeller rod 34 and the spray nozzle 4, ensures the smooth operation of the rotating component 3 and the stability of the water spray coverage. At the same time, the sealing ring design of the filter screen can prevent water from leaking from the installation gap, and the detachable slot structure facilitates regular cleaning of accumulated impurities, extending the service life of the device.

[0029] In this specific embodiment, the cylindrical sidewall of the spray head 4 is laser-drilled with 12-24 nozzles, each 3-5 mm in diameter. All nozzles are arranged at equal intervals along the axis of the spray head 4, forming three annular arrays. Each annular array contains 4-8 nozzles, with the distance between adjacent annular arrays being 1 / 4 of the height of the spray head 4. The lowest annular array is 2-3 cm from the bottom of the spray head 4, and the nozzle axis forms an outward expansion angle of 15°-30° with the radial direction of the spray head 4. The beneficial effects are: when the spray head 4 is driven to rotate by the propeller rod 34, the multiple annular array nozzles form a three-dimensional water curtain covering a radius of 3-5 meters. The outward expansion angle causes the water flow to spray out in a scattering manner, achieving uniform saturation of the soil in the tree root zone in conjunction with the rotational motion. Furthermore, the axially distributed annular array can simultaneously irrigate soil layers of different depths, avoiding water concentration or irrigation blind spots caused by traditional single-plane nozzles, significantly improving water resource utilization.

[0030] Working principle: When irrigation water flows from the inlet pipe 2 into the transfer pipe 1, it first passes through the filter screen installed at the connection of the inlet pipe 2 to filter impurities. Then, the water flow impacts the propeller rod 34 in the rotating assembly 3. The helical blades, whose inclination direction matches the water flow direction, drive the connecting rod 33 to rotate around the axis of the bearing 32 under the action of hydrodynamic force. The torque is transmitted to the spray head 4 through the support rod 35, so that the spray head 4 can rotate freely around the top of the transfer pipe 1 through the rotational cooperation of the connecting pipe 5 and the sealing ring 6. During the rotation of the spray head 4, the internal pressure water... The water flow is sprayed out in a scattering pattern from the circumferentially distributed annular array of nozzles. The outward expansion angle of the nozzles creates a three-dimensional irrigation area with a radius of 3-5 meters. The four insert rods 73 on the bottom surface of the base plate 72 in the installation component 7 are inserted into the ground to form a stable support, preventing the device from overturning under the reaction force of the water flow. Throughout the process, the sealing ring 6 maintains the seal between the transfer pipe 1 and the spray head 4 under dynamic rotation by wrapping the top of the transfer pipe 1 with the inner wall and embedding the annular groove of the connecting pipe 5 with the outer wall. This ensures irrigation efficiency and device reliability.

The power supply is also common knowledge in the field.
