In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the fact that a person of ordinary skill in the art can realize it, and when the combination of technical solutions appears to be contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is also not within the protection scope of the present application.

[0039] Please refer to Figure 1 and Figure 2 In a preferred embodiment of the present application, a tea garden planting irrigation system is provided, which comprises a main water pipe 100, a rotating sleeve pipe 200, and an outer insertion pipe 300.

[0040] The bottom of the main water pipe 100 is provided with an irrigation branch pipe 110 extending downward and communicating with the main water pipe 100, and the peripheral wall of the irrigation branch pipe 110 is provided with irrigation holes 111.

[0041] The rotating sleeve 200 is rotatably fitted around the outer periphery of the irrigation branch pipe 110. The central hole 210 of the rotating sleeve 200 fits against the outer peripheral wall of the irrigation branch pipe 110, thereby reducing water flow through the gaps. The rotating sleeve 200 has an arc-shaped outlet 220 at a height corresponding to the irrigation hole 111. The extension path of the arc-shaped outlet 220 is a chord with a certain arc length. Rotation within a preset angle range can align the irrigation hole 111 with the arc-shaped outlet 220. In this embodiment, the central angle of the arc-shaped outlet 220 is 160°.

[0042] An external insertion tube 300 is fitted around the outer periphery of a rotating sleeve 200, which is located between the irrigation branch pipe 110 and the external insertion tube 300. This isolates the rotating sleeve 200 from the soil layer, preventing its rotation from being affected by the soil and reducing rotational resistance. The external insertion tube 300 has an outlet 310 corresponding to the irrigation hole 111. Its upper end is connected and fixed to the main water pipe 100, while its lower end is used to insert into the soil layer. The external insertion tube 300 has a central hole 301 that fits into the rotating sleeve 200. The lower end of the external insertion tube 300 is inserted into the soil layer for fixation, simultaneously fixing and supporting the position of the main water pipe 100. The lower end of the external insertion tube 300 is cone-shaped for easy embedding into the soil layer.

[0043] The rotating sleeve 200 can rotate to connect the irrigation hole 111 with the outlet 310, or to separate the irrigation hole 111 from the outlet 310 by the peripheral wall of the rotating sleeve 200, thereby achieving irrigation control. Furthermore, the rotation of the rotating sleeve 200 can adjust the flow rate between the irrigation hole 111 and the outlet 310, precisely controlling the amount of irrigation water. Figure 5 As shown, at this time, the irrigation hole 111 is connected to the corresponding outlet 310, and the irrigation hole 111, the arc-shaped outlet 220, and the outlet 310 are aligned, allowing water to seep into the soil layer through the irrigation hole 111, the arc-shaped outlet 220, and the outlet 310. Figure 6 As shown, at this time, the irrigation hole 111 and the corresponding outlet 310 are separated by the circumferential wall of the rotating sleeve 200, so that water cannot pass through the rotating sleeve 200 and enter the outlet 310 and the soil layer, and the irrigation hole 111 cannot output water for irrigation.

[0044] In a preferred embodiment of the present application, the tea garden planting irrigation system can accurately control the communication state of the irrigation hole 111 and the water outlet 310 by adjusting the rotation of the rotating sleeve 200, realize accurate irrigation of tea trees, and reduce the exposure of water on the surface of the soil layer because the irrigation hole 111 and the water outlet 310 are in the soil layer, effectively reduce the evaporation of water, thereby saving water resources; the present application can also adjust the position of the rotating sleeve 200 to flexibly change the flow area between the irrigation hole 111 and the water outlet 310 according to the water demand of tea trees in different growth periods, adjust the water supply, and meet the water demand of tea trees in different growth stages. The tea garden planting irrigation system of the present application not only improves the accuracy and uniformity of irrigation, but also saves water resources, enhances the adaptability and flexibility of the system, and provides an efficient and environmentally friendly irrigation solution for tea garden planting.

[0045] Referring to Figure 1 and Figure 2 In some embodiments of the present application, a plurality of irrigation holes 111 are arranged vertically, a plurality of water outlet arc-shaped strip openings 220 are correspondingly provided, and the water outlet arc-shaped strip openings 220 at different heights are circumferentially staggered to enable the irrigation holes 111 at different heights to be in communication or isolation with the water outlets 310, that is, as the rotation angle of the rotating sleeve 200 changes, the irrigation holes 111 at different heights and the corresponding water outlets 310 can present different states (communication or isolation), for example, the upper irrigation holes 111 are in communication with the corresponding water outlets 310, and the lower irrigation holes 111 are isolated from the corresponding water outlets 310, thereby realizing control of the irrigation height, and adjusting the irrigation height by rotating the rotating sleeve 200 to adapt to irrigation of different soil layer depths, realize accurate irrigation and adjustable irrigation.

[0046] Referring to Figure 7 In some embodiments of the present application, the staggered angles of the adjacent two water outlet arc-shaped strip openings 220 are the same and the staggered directions are the same rotation direction, and the rotation center is the center axis of the rotating sleeve 200; that is, the water outlet arc-shaped strip openings 220 are gradually staggered in the preset angle along the rotation direction from top to bottom. The water outlet arc-shaped strip openings 220 project to form a projection area on a horizontal plane, such as Figure 12 The projection areas of all the water outlet arc-shaped strip openings 220 have a coincident area 211, in this embodiment, the central angle of the arc chord of the water outlet arc-shaped strip opening 220 is 160°, the adjacent water outlet arc-shaped strip openings 220 are staggered by 40° along the circumference, the irrigation holes 111 are vertically arranged and vertically aligned, and the water outlet arc-shaped strip openings 220 correspondingly have four, so there will be a coincident area 211 with a central angle of 40°. Such as Figure 12As shown, the existence of the coinciding area 211 makes the four water outlet arc-shaped slits 220 align with the corresponding irrigation holes 111 at the position of the coinciding area 211 of the four water outlet arc-shaped slits 220, so that the four water outlet arc-shaped slits 220 are simultaneously aligned with the corresponding irrigation holes 111, so that the four irrigation holes 111 are simultaneously communicated with the corresponding water outlets 310, and irrigation of all irrigation holes 111 at multiple vertical positions is realized. Moreover, due to the gradually staggered arrangement of the water outlet arc-shaped slits 220 from top to bottom along the preset angle in the rotating direction, after the rotating sleeve 200 rotates in one direction, the irrigation holes 111 from top to bottom can be sequentially communicated with the corresponding water outlets 310 until all of them are communicated, and then continue to rotate to sequentially cut off the irrigation holes 111 from top to bottom and the corresponding water outlets 310 until all of them are cut off, so as to adapt to multiple working conditions and irrigation requirements. For example, when the weather is relatively hot, the irrigation depth can be appropriately deep, so that the lower irrigation holes 111 are communicated with the corresponding water outlets 310 to realize deep irrigation and reduce water evaporation. In addition, adaptive irrigation can be performed according to the root depth of the tea tree to realize deep irrigation. Of course, all irrigation holes 111 can be communicated with the corresponding water outlets 310 to realize multi-position omnidirectional irrigation. For example, Figure 8 As shown, at this time, all irrigation holes 111 are cut off from the corresponding water outlets 310 by the pipe wall of the rotating sleeve 200, and then the rotating sleeve 200 starts to rotate, and rotates to the state shown in Figure 9 As shown, the uppermost irrigation hole 111 is communicated with the corresponding water outlet 310, and then it can continue to rotate in the same direction to the state shown in Figure 10 As shown, the second irrigation hole 111 from the top is also communicated with the corresponding water outlet 310, and then it continues to rotate to the state shown in Figure 11 As shown, the third irrigation hole 111 from the top is also communicated with the corresponding water outlet 310, and then it continues to rotate to the state shown in Figure 12 As shown, the fourth irrigation hole 111 from the top is also communicated with the corresponding water outlet 310, at this time, all irrigation holes 111 are communicated with the corresponding water outlets 310, and then it can continue to rotate, and the uppermost irrigation hole 111 will be cut off first, and the irrigation holes 111 from top to bottom will be cut off one by one until it returns to the state shown in Figure 9 Thus, the state switching of the rotating sleeve 200 rotating one round is realized, and it can be known that the rotating sleeve 200 rotating one round can realize multiple state switching and adjust the irrigation depth and quantity, thereby improving the adaptability.

[0047] Referring to Figure 3In some embodiments of the present application, the outer insertion tube 300 is provided with an outwardly expanded horizontal mounting plate 320 at the upper end thereof, which is used to contact the surface of the soil layer; thus, when the outer insertion tube 300 is installed and inserted into the soil layer, it only needs to be forced to be inserted until the horizontal mounting plate 320 contacts the surface of the soil layer, at which time it is difficult to further press the outer insertion tube 300, thereby achieving control of the insertion depth of the outer insertion tube 300 and avoiding that the outer insertion tube 300 is inserted too shallowly or too deeply. The horizontal mounting plate 320 is provided with two groups of hoops 330, each group of hoops 330 is provided with two hoops 330, one end of the hoop 330 is hinged to the horizontal mounting plate 320, and the other end is provided with a connecting block 331 provided with a connecting hole 332; the connecting holes 332 of the connecting blocks 331 of the two hoops 330 in the same group are aligned and a fastener 340 is installed thereon, thereby clamping the main water pipe 100 tightly and achieving the connection and fixation of the main water pipe 100 and the outer insertion tube 300. The fastener can be a bolt and a nut. The two groups of hoops 330 can achieve stable connection with the main water pipe 100 and are convenient to disassemble and install.
