[0024] When it is necessary to expand the irrigation area, the extension tube body is moved into the U-shaped tube. The embedding effect of the oblique push block 2 can realize the rotation of the water guide ring and the overlap of the water outlet hole, so that water can be smoothly introduced into the extension tube body and drip irrigated through the drip irrigation head. This design not only improves the irrigation efficiency, but also ensures the uniformity of irrigation.

[0025] At the same time, when the extension tube body is not needed, it only needs to be moved out of the U-shaped tube. The disengagement of the oblique push block 2 will reset the torsion spring, thereby driving the water guide ring to rotate and close the water outlet, effectively preventing the waste of water resources and soil erosion.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 7 As shown:

[0038] Embodiment 1: The present invention provides an irrigation device for saline-alkali land treatment, comprising:

[0039] The main water pipe mechanism 1 comprises a main water pipe assembly 11 and a branch pipe 12 arranged on the main water pipe assembly 11;

[0040] Among them, the main water pipe assembly 11 is the backbone of the irrigation system and is responsible for transporting water from the source to each branch point;

[0041] The branch pipe 12 is a pipe extending from the main water pipe assembly 11 and is used to further distribute the water source to various irrigation points.

[0042] The water supply pipe mechanism 2 includes a water supply pipe assembly 21 interconnected with the branch pipe 12, and an extension pipe assembly 22 installed on the water supply pipe assembly 21;

[0043] The water supply pipe assembly 21 includes a connecting hose 211, one end of which is fixedly connected to an external joint 212, the other end of which is fixedly connected to a U-shaped pipe 213, and the bottom of the U-shaped pipe 213 is fixedly connected to a plurality of drip irrigation heads 214 and a positioning rod 215;

[0044] The connecting hose 211 is used to connect the external connector 212 and the U-shaped tube 213 to provide a water delivery channel. The connecting hose 211 has a certain flexibility, which is convenient for adjustment according to the location of the irrigation point.

[0045] The external joint 212 is the part connected to the branch pipe 12 to ensure that the water source can smoothly enter the water supply pipe assembly 21;

[0046] The U-shaped tube 213 is used for irrigation and is combined with the oblique push block 222 from the extension tube assembly 22 to achieve water source transfer and irrigation control;

[0047] The drip irrigation head 214 is disposed at the bottom of the U-shaped tube 213 and is used to directly deliver water to the roots of plants in a drip irrigation manner, thereby reducing evaporation and waste of water.

[0048] The positioning rod 215 is used to firmly insert the water supply pipe assembly 21 into the soil to prevent displacement or tipping during irrigation.

[0049] The extension tube assembly 22 includes an extension tube body 221, one end of the extension tube body 221 is fixedly connected to an oblique push block 222, and the lower side of the extension tube body 221 is fixedly connected to a plurality of drip irrigation heads 223 and a positioning rod 224;

[0050] The extension pipe body 221 is used as a water source conveying channel, connected to the U-shaped pipe 213 of the water supply pipe assembly 21, and is connected to the U-shaped pipe 213 by a second inclined push block 222;

[0051] The second oblique push block 222 can be embedded in the U-shaped tube 213 to achieve the connection between the extension pipe assembly 22 and the water supply pipe assembly 21 .

[0052] The second oblique push block 222 can be inserted into the U-shaped tube 213;

[0053] When in use, the staff can connect multiple sections of the main water pipe assembly 11 to each other, and then connect the external water supply system to the water inlet end of the main water pipe assembly 11 to ensure a stable water supply;

[0054] Connect the external joint 212 to the branch pipe 12, set the water supply pipe assembly 21 outside the sapling, and insert the second inclined push block 222 into the U-shaped pipe 213 to connect the two, and place the sapling in a position surrounded by the water supply pipe assembly 21 and the extension pipe assembly 22;

[0055] Pressing down the water supply pipe assembly 21 and the extension pipe assembly 22 can make the positioning rod 1 215 and the positioning rod 224 embedded in the soil together, thereby avoiding separation;

[0056] Turn on the switch of the external water supply system, and the water source begins to enter the U-shaped pipe 213 and the extension pipe body 221 through the main water pipe assembly 11, the branch pipe 12, and the connecting hose 211. When the water source flows through the drip irrigation head 1 214 and the drip irrigation head 223, it is evenly delivered to the roots of the plants in a drip irrigation manner to achieve precise irrigation;

[0057] During the irrigation process, the irrigation water volume and irrigation time can be adjusted in time according to parameters such as plant growth and soil moisture. The connection status of various components of the irrigation device and the blockage of the drip irrigation head should be checked regularly to ensure the irrigation effect.

[0058] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that a connecting piece 216 is further provided inside the U-shaped tube 213;

[0059] The connecting member 216 includes a blocking ring 2161, a water guide ring 2162 and a torsion spring 2163. A connecting rod 2164 is fixedly connected to one side of the blocking ring 2161. A positioning ring 2165 is fixedly connected to the end of the connecting rod 2164. A plurality of inclined push blocks 1 2166 are fixedly connected to one side of the water guide ring 2162. A plurality of water outlet holes 1 are formed on the blocking ring 2161. A plurality of water outlet holes 2 are formed on the water guide ring 2162.

[0060] The blocking ring 2161 is used as the base part of the connecting member 216, and is used to block the water source in the U-shaped tube 213 when the water guide ring 2162 is not rotating, so as to prevent the water from flowing out uncontrolled.

[0061] The connecting rod 2164 supports and connects the blocking ring 2161 and the positioning ring 2165;

[0062] Positioning ring 2165: used to fix one end of the torsion spring 2163 to ensure that the torsion spring 2163 can stably drive the water guide ring 2162 to rotate and reset;

[0063] The water guide ring 2162 is provided with a water outlet hole 2. When it coincides with the water outlet hole 1 on the sealing ring 2161, water is allowed to pass through and flow to the extension pipe assembly 22. The water guide ring 2162 is embedded in the connecting rod 2164 by rotation to achieve relative movement with the sealing ring 2161.

[0064] One end of the torsion spring 2163 is embedded in the positioning ring 2165, and the other end is embedded in the water guide ring 2162. When the inclined push block 222 is embedded in the U-shaped tube 213, the torsion spring 2163 is compressed and stores energy; when the inclined push block 222 is moved out, the torsion spring 2163 releases energy and drives the water guide ring 2162 to rotate back to the initial position.

[0065] Specifically, the water guide ring 2162 is rotatably embedded in the connecting rod 2164, one end of the torsion spring 2163 is embedded in the positioning ring 2165, and the other end of the torsion spring 2163 is embedded in the water guide ring 2162. The torsion spring 2163 drives the water guide ring 2162 to rotate and make the water outlet hole 1 and the water outlet hole 2 completely staggered.

[0066] Specifically, when the second oblique push block 222 is embedded in the U-shaped tube 213, the first oblique push block 2166 drives the water guide ring 2162 to rotate, and the first water outlet hole and the second water outlet hole are completely overlapped.

[0067] As can be seen from the above, when the extension tube body 221 is needed, the extension tube body 221 is moved so that the oblique push block 222 is embedded in the U-shaped tube 213. When the oblique push block 222 is embedded in the U-shaped tube 213, the oblique push block 1 2166 drives the water guide ring 2162 to rotate and the torsion spring 2163 is twisted, and at the same time, the water outlet hole 1 and the water outlet hole 2 are completely overlapped. At this time, the water in the U-shaped tube 213 can be introduced into the extension tube body 221 and drip-irrigated through the drip irrigation head 223. Then, the combined U-shaped tube 213 and the extension tube body 221 are moved downward, and the positioning rod 1 215 and the positioning rod 224 are embedded in the soil together, thereby avoiding the oblique push block 222 and the U-shaped tube 213 from being separated.

[0068] When the extension tube body 221 is no longer needed, the extension tube body 221 is moved to separate the oblique push block 222 from the U-shaped tube 213. After the oblique push block 222 is removed, the torsion spring 2163 is reset to drive the water guide ring 2162 to rotate, and make the water outlet hole 1 and the water outlet hole 2 completely offset. At this time, water cannot pass through the sealing ring 2161.

[0069] like Figure 8 As shown:

[0070] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that the main water pipe assembly 11 includes a main water pipe 111, one end of the main water pipe 111 is fixedly connected to one end of a telescopic pipe 112, and the other end of the telescopic pipe 112 is fixedly connected to a main water pipe 2 113;

[0071] Among them, the main water pipe 111 is used to transport water from the source to each branch point;

[0072] One end of the telescopic tube 112 is fixedly connected to one end of the main water pipe 1 111, and the other end of the telescopic tube 112 is fixedly connected to one end of the main water pipe 2 113, so as to ensure that the water source can smoothly flow from the main water pipe 1 111 through the telescopic tube 112 and then enter the main water pipe 2 113;

[0073] The second main water pipe 113 can be inserted into the adjacent first main water pipe 111. This design is not only convenient for installation and disassembly, but also allows the layout of the irrigation system to be adjusted according to actual needs.

[0074] The open end of the main water pipe 113 can be connected to an external water supply system so as to introduce water into the irrigation system;

[0075] The open end of the main water pipe 111 can be blocked when it is at the end.

[0076] Specifically, the second main water pipe 113 can be embedded in the adjacent first main water pipe 111, the open end of the second main water pipe 113 can be connected to the external water supply system, and the open end of the first main water pipe 111 can be blocked.

[0077] As can be seen from the above, the telescopic tube 112 can be telescoped to extend the distance, and at the same time the directions of the main water pipe 1 111 and the main water pipe 2 113 can be changed. The main water pipe 2 113 is embedded in the adjacent main water pipe 1 111 for connection, thereby extending the drip irrigation distance and increasing the drip irrigation facilities.

[0078] like Figure 8 and Fig. 9 As shown:

[0079] Embodiment 4: This embodiment is basically the same as the previous embodiment, except that it further comprises a positioning support mechanism 3, including a support assembly 31 embedded in the outer side of the main water pipe assembly 11, and a positioning assembly 32 rotatably embedded in the outer side of the support assembly 31.

[0080] Specifically, the support assembly 31 includes a support rod 311 and an upper clamp 312. The lower end of the support rod 311 is fixedly connected to a positioning steel chisel 313, the upper end of the support rod 311 is fixedly connected to a lower clamp 314, the upper side of the lower clamp 314 is also fixedly connected to an axial hole frame 315, one end of the upper clamp 312 is fixedly connected to a rotating rod 316, and the other end of the upper clamp 312 is penetrated by a threaded rod 317;

[0081] The support rod 311 is the skeleton of the support assembly, one end of which is fixed on the ground by a positioning steel drill 313, and the other end is connected to the lower clamp 314;

[0082] The upper clamp 312 and the lower clamp 314 are a pair of clamps used together. They can be assembled and rotated to be embedded in the outer side of the main water pipe 113 to provide stable support for the main water pipe.

[0083] The shaft hole frame 315 is fixed on the upper side of the lower clamp 314 and is used to support the rotating rod 316;

[0084] The rotating rod 316 is fixedly connected to one end of the upper clamp 312, and can rotate on the shaft hole frame 315, so that the upper clamp 312 can be fine-tuned relative to the lower clamp 314;

[0085] The threaded rod 317 penetrates the upper clamp 312 and is embedded in the lower clamp 314. The tightness between the upper clamp 312 and the lower clamp 314 can be adjusted by rotating the threaded rod 317, thereby ensuring that they can firmly clamp the main water pipe 113.

[0086] The outer side of the second main water pipe 113 is also fixedly connected to a limited retaining ring 114;

[0087] The limit stop ring 114 is an annular component fixedly connected to the outside of the main water pipe 113, and its function is to limit the position of the upper clamp 312 and the lower clamp 314 after assembly to prevent them from sliding or falling off due to excessive force.

[0088] Specifically, the rotating rod 316 is rotatably embedded in the shaft hole frame 315, and the threaded rod 317 can penetrate the upper clamp 312 and then be embedded in the lower clamp 314. After the upper clamp 312 and the lower clamp 314 are combined, they can be rotatably embedded in the outer side of the main water pipe 113, and the limit ring 114 can limit the combined upper clamp 312 and the lower clamp 314.

[0089] Specifically, the positioning assembly 32 includes an L-shaped connecting rod 321, one end of the L-shaped connecting rod 321 is fixedly connected to a collar 322, and the other end of the L-shaped connecting rod 321 is fixedly connected to a positioning steel drill 323;

[0090] One end of the L-shaped connecting rod 321 is rotatably engaged with the supporting rod 311 through a collar 322, and the other end is fixedly connected to a positioning steel drill 323;

[0091] The collar 322 allows the L-shaped connecting rod 321 to rotate on the support rod 311, thereby adjusting the insertion angle and depth of the positioning steel drill 323 to adapt to different terrain and soil conditions;

[0092] The second positioning steel chisel 323 is used to firmly fix the positioning support mechanism 3 on the ground to prevent it from moving or tilting during the irrigation process.

[0093] The collar 322 is rotatably engaged with the support rod 311 .

[0094] As can be seen from the above, the support rod 311 is moved to a suitable position, the L-shaped connecting rod 321 is rotated to be in a suitable position, the positioning steel drill 1 313 is moved down and embedded in the soil, and then the L-shaped connecting rod 321 is moved down to make the ring 322 slide down on the support rod 311, and the positioning steel drill 2 323 is embedded in the soil, which can be further fixed;

[0095] Place the main water pipe 113 on the lower clamp 314, and position the lower clamp 314 through the limit ring 114, rotate the upper clamp 312 to make it rotate around the axial hole frame 315 through the rotating rod 316, when the upper clamp 312 is located on the upper side of the main water pipe 113, rotate the threaded rod 317 to penetrate the upper clamp 312 and then embed into the lower clamp 314, so as to fix the main water pipe 113.

[0096] Application Process:

[0097] 1. Preparation

[0098] Assembling the irrigation system:

[0099] According to the needs of the irrigation area, select a suitable number of multi-section main water pipe assemblies 11, and make the main water pipe 2 113 embedded in the adjacent main water pipe 1 111;

[0100] Then the main water pipe 2 113 at the starting end is connected to the external water supply system, and the main water pipe 1 111 at the end is blocked to form a complete irrigation network;

[0101] If it is necessary to extend the drip irrigation distance or change the direction, this can be achieved through the telescopic and bending functions of the telescopic tube 112.

[0102] Install the water supply pipe mechanism and extension pipe assembly:

[0103] Firmly connect the external connector 212 at one end of the connecting hose 211 to the branch pipe 12;

[0104] According to the location of the saplings and the irrigation requirements, the U-shaped pipe 213 of the water supply pipe assembly 21 and the extension pipe body 221 of the extension pipe assembly 22 are arranged and installed;

[0105] Ensure that the second oblique push block 222 can be smoothly inserted into the U-shaped tube 213 and achieve a stable connection between the two.

[0106] Install the positioning support mechanism:

[0107] Move the support rod 311 of the support assembly 31 to a suitable position, and then move the positioning steel chisel 313 downward to embed it into the soil;

[0108] Then, the L-shaped connecting rod 321 is rotated to be in a suitable position, and the positioning steel bar 323 is moved downward to be embedded in the soil, thereby fixing the irrigation device;

[0109] Place the second main water pipe 113 on the lower clamp 314 and limit it by the limit ring 114;

[0110] Then rotate the upper clamp 312 so that it rotates around the shaft hole frame 315 to the upper side of the main water pipe 2 113 through the rotating rod 316;

[0111] Finally, the threaded rod 317 is rotated to pass through the upper clamp 312 and then embedded in the lower clamp 314 to fix the main water pipe 113.

[0112] 2. Irrigation stage

[0113] Connecting to an external water supply:

[0114] Connect an external water supply system such as a water pump, a water tank, etc. to the water inlet end of the main water pipe assembly 11, that is, the open end of the main water pipe 2 113, to ensure a stable and continuous supply of water.

[0115] Turn on irrigation:

[0116] Turn on the switch of the external water supply system to start irrigation. The water source enters the U-shaped pipe 213 and the extension pipe body 221 through the main water pipe assembly 11, the branch pipe 12, and the connecting hose 211.

[0117] In the initial state, due to the action of the torsion spring 2163, the water outlet hole 2 on the water guide ring 2162 is completely offset from the water outlet hole 1 on the blocking ring 2161, and the water flow is blocked in the U-shaped tube 213, so that the drip irrigation head 1 214 can work;

[0118] When the drip irrigation range needs to be extended, the extension tube body 221 is moved to embed the oblique push block 222 into the U-shaped tube 213, and the oblique push block 1 2166 is pushed to drive the water guide ring 2162 to rotate, so that the water outlet hole 1 and the water outlet hole 2 completely overlap, allowing water to flow through, so that the drip irrigation head 1 214 and the drip irrigation head 2 23 can work at the same time.

[0119] Drip irrigation:

[0120] When the external water supply system is turned on, water will be evenly delivered to the roots of the plants through drip irrigation head 1 214 and drip irrigation head 223 in a drip irrigation manner.

[0121] Adjust the irrigation water volume and irrigation time in time according to parameters such as plant growth and soil moisture.

[0122] 3. Maintenance Phase

[0123] Monitoring and Adjustment:

[0124] During the irrigation process, regularly check the connection status of each component of the irrigation device and the blockage of the drip irrigation head.

[0125] If the connection is found to be loose or the drip irrigation head is clogged, adjust and clean it in time.

[0126] End of irrigation:
