[0030] By adopting the above technical solution, when in use, water is first added to the water tank 2. Wheels are installed at the bottom of the frame 1 to facilitate the adjustment and movement of the device to the area where trees need to be watered. The water flow of irrigation can be automatically controlled by controlling the rotation speed of the impeller of the liquid pump 5, so as to make irrigation more precise. The diameter of the fixed frame 62 and the water spray frame 64 is much larger than the diameter of the trunk of the big tree. The fixed frame 62 and the water spray frame 64 are both opened on the side away from the water tank 2. When irrigation is carried out, the frame 1 is moved to the big tree that needs to be watered, and then the frame 1 is moved so that the trunk of the big tree enters the fixed frame 62 and the water spray frame 64 from the opening. By starting the liquid pump 5, the water in the water tank 2 enters the first hose 4 through the water pipe 3, and enters the inside of the movable frame 63 from the inside of the first hose 4. , and then enters the interior of the water spray rack 64. The water entering the water spray rack 64 enters the interior of the spray cover 67 through the second hose 65 and the drainage pipe 66. The spray cover 67 is provided with a plurality of drainage holes on the side away from the drainage pipe 66, so that water can be sprayed out in the form of droplets for irrigation, thereby improving the uniformity of irrigation. When watering, the output shaft of the first motor 72 rotates, so that the gear 73 rotates. Under the action of the meshing of the gear 73 and the gear ring 71, the gear ring 71 rotates with the water spray rack 64, so that part of the spray cover 67 at the water spray rack 64 can be rotated to the side of the tree trunk away from the frame 1, so as to facilitate the irrigation of the area at the side of the tree trunk away from the frame 1. In this way, it can be ensured that the soil at the root of the tree can be irrigated, so that the irrigation is more uniform, thereby improving the effect of irrigation.

[0031] It should be noted that the movable frame 63 rotates around the inside of the fixed frame 62, and the design of the ball 74 is conducive to reducing the friction generated when the movable frame 63 moves. In actual use, a solenoid valve can be installed inside the drainage pipe 66 to control part of the spray hood 67 not to spray water during watering, so as to avoid repeated spraying of part of the soil around the tree trunk to affect the uniformity of watering and avoid waste of water resources.

[0032] Specifically, Figures 2 to 7As shown, the bottom of the discharge pipe 66 is rotatably connected to a large pipe 68, and a small pipe 69 is provided at the bottom of the large pipe 68. The end of the small pipe 69 away from the large pipe 68 is rotatably connected to the inner side of the water spray frame 64. The outer wall of the small pipe 69 is located inside the large pipe 68 and is fixedly connected to a piston 610. A first spring 614 is fixedly connected between the small pipe 69 and the large pipe 68. The outer wall of the piston 610 fits the inner wall of the large pipe 68. A cavity 611 is provided inside the side of the water spray frame 64 close to the movable plate 61. A plurality of third hoses 612 are fixedly plugged inside the cavity 611. A ventilation pipe 613 is fixedly plugged on the side of the third hose 612 away from the cavity 611. The outer wall of the large pipe 68 is fixedly plugged with the ventilation pipe 613. The lower part of the water spray frame 64 is fixedly connected to The air source component 8, the bottom of the water spray frame 64 is fixedly connected with a fixing ring 10, the middle part of the fixing ring 10 is slidably connected with a slip ring frame 11, the inner side of the fixing ring 10 is fixedly connected with a fixing frame 12, the inside of the fixing frame 12 is fixedly connected with an electric telescopic rod 13, the output shaft of the electric telescopic rod 13 is fixedly connected to the inner part of the slip ring frame 11, the bottom end of the outer part of the slip ring frame 11 is fixedly connected with an extrusion plate 14, the air source component 8 includes an air bag 81 fixedly connected to the bottom of the extrusion plate 14, the air source component 8 also includes a fixing plate 82 fixedly connected to the outer bottom of the fixing ring 10, the top of the air bag 81 is fixedly inserted with a sleeve 83, the inner top of the sleeve 83 is slidably connected with a through pipe 84, and the top of the through pipe 84 is inserted into the interior of the cavity 611.

[0033] By adopting the above technical solution, the discharge pipe 66 is fixedly connected to a round rod, and one end of the round rod away from the discharge pipe 66 is fixedly connected to a rotating plate, and the rotating plate is fixedly connected to the water spray frame 64. While watering, the output shaft of the electric telescopic rod 13 is extended to make the slip ring frame 11 move downward, thereby making the extrusion plate 14 move downward. At this time, the extrusion plate 14 squeezes the airbag 81, so that the gas inside the airbag 81 enters the through-tube 84 from the sleeve 83, and enters the interior of the cavity 611 through the through-tube 84. The gas entering the interior of the cavity 611 enters the third hose 612, and then enters the ventilation pipe 613, and finally enters the interior of the large pipe 68 through the ventilation pipe 613. Under the action of the gas pressure, the piston 610 brings the small tube 69 away from the first spring. The first spring 614 is in a stretched state. At this time, the small tube 69 and the large tube 68 move relative to each other, so that the length formed between the small tube 69 and the large tube 68 changes. In this process, the liquid spraying cover 67 can be swung, so that water is sprayed from the liquid spraying cover 67 at different angles. In conjunction with the rotation of the water spraying frame 64, different positions of the soil around the tree trunk can be irrigated, so that the uniformity of soil irrigation in the area around the tree trunk is further improved, and the effect of tree irrigation is further improved. When the output shaft of the electric telescopic rod 13 contracts, the airbag 81 stretches, and under the elastic force of the first spring 614, it is convenient for the piston 610 and the small tube 69 to be reset. In this process, the liquid spraying cover 67 swings and resets.

[0034] It should be noted that the ventilation pipe 613 is made of rigid material to ensure that the multiple spray covers 67 swing synchronously, and an O-ring can be installed on the top of the inner wall of the sleeve 83 to ensure the sealing between the sleeve 83 and the through pipe 84.

[0035] Specifically, Figure 2 , Figure 5 and Figure 6 As shown, a plurality of connecting tubes 15 are fixedly plugged into the bottom of the fixing ring 10, an insertion assembly 9 is arranged outside the connecting tube 15, and the insertion assembly 9 includes a round tube 91 fixedly connected to the bottom of the slip ring frame 11, an insertion tube 92 is arranged below the round tube 91, and the bottom of the insertion tube 92 is arranged obliquely.

[0036] By adopting the above technical solution, when the output shaft of the electric telescopic rod 13 is extended, the sliding ring frame 11 moves downward, so that the round tube 91 and the insertion tube 92 move downward, so that the insertion tube 92 is inserted into the soil around the trunk of the tree, so that many small holes are pierced in the soil around the trunk, so that the irrigation water can penetrate the soil inside the soil, reduce the surface runoff of the irrigation water, and further improve the irrigation effect.

[0037] Specifically, Figure 6As shown, a slide 93 is slidably connected to the top of the insertion tube 92 , the top of the slide 93 is fixedly connected to the round tube 91 , and a third spring 94 is fixedly connected between the bottom of the slide 93 and the insertion tube 92 .

[0038] By adopting the above technical solution, in the process of the insertion tube 92 moving downward and penetrating into the soil around the trunk of the tree, if the bottom of the insertion tube 92 contacts the root of the tree, the insertion tube 92 and the slide 93 slide relative to each other, and the third spring 94 is compressed, thereby preventing the insertion tube 92 from injuring the tree roots and affecting the health of the tree. When the bottom of the insertion tube 92 contacts hard stones, the insertion tube 92 and the slide 93 slide relative to each other, thereby preventing the insertion tube 92 from being damaged.

[0039] Specifically, Figures 3 to 7 As shown, a water cavity 16 is opened inside the fixing ring 10 above the connecting pipe 15, a leaking pipe 17 is fixedly inserted at the top of the fixing ring 10 in the water cavity 16, the top of the leaking pipe 17 is inserted into the inside of the water spray frame 64, a sliding rod 18 is fixedly connected to the top of the slip ring frame 11, the top of the sliding rod 18 penetrates into the water cavity 16 and is fixedly connected to a blocking block 19, the sliding rod 18 is fixedly connected to the fixing ring 10, and the interior of the connecting pipe 15 is hollow.

[0040] By adopting the above technical solution, when the output shaft of the electric telescopic rod 13 is extended, the slip ring frame 11 moves downward, and the block 19 does not block the bottom of the leakage pipe 17, so that the water entering the water spray frame 64 enters the water cavity 16 through the leakage pipe 17 and enters the connecting pipe 15. When the insertion pipe 92 moves downward and penetrates into the soil around the trunk of the tree, the water entering the connecting pipe 15 flows into the insertion pipe 92, thereby injecting part of the water into the soil, which is convenient for the tree roots to absorb water.

[0041] It should be noted that the inner diameter of the leakage pipe 17 can be set smaller to avoid affecting the normal irrigation of the spray hood 67. When the insertion tube 92 is not inserted into the soil, some water will flow out and the water will also be irrigated on the soil. When the output shaft of the electric telescopic rod 13 is fully retracted, the blocking block 19 blocks the bottom of the leakage pipe 17 to prevent water from entering the water cavity 16.

[0042] The inner wall of the insertion tube 92 is in contact with the outer wall of the connecting tube 15 .

[0043] By adopting the above technical solution, when the output shaft of the electric telescopic rod 13 is fully retracted, the bottom of the connecting tube 15 is below the bottom of the insertion tube 92. When the output shaft of the electric telescopic rod 13 is retracted, the connecting tube 15 can clear the insertion tube 92 to prevent the inside of the insertion tube 92 from being blocked by soil. It should be noted that a filter screen is installed at the bottom of the connecting tube 15.

[0044] Specifically, Figure 1and Figure 2 As shown, a small plate 20 is fixedly connected to the right side of the water tank 2 below the liquid pump 5, a second motor 21 is fixedly connected to the top of the small plate 20, an output shaft of the second motor 21 passes through the small plate 20 and is fixedly connected to a screw rod 22, and an outer wall of the screw rod 22 is threadedly connected to the movable plate 61.

[0045] By adopting the above technical solution, when the device needs to be transported to a designated tree, the output shaft of the second motor 21 rotates to drive the screw 22 to rotate, so that the movable plate 61 moves upward with the fixed frame 62, the water spray frame 64 and part of the fixed ring 10, thereby preventing the bottom of the insertion tube 92 from being too close to the ground when the device moves. When watering is required, the output shaft of the second motor 21 rotates in another direction, so that the movable plate 61 moves downward with the fixed frame 62, the water spray frame 64 and part of the fixed ring 10, thereby making the bottom of the insertion tube 92 close to the ground.

[0046] Working principle: first add water to the water tank 2, and install wheels at the bottom of the frame 1 to facilitate the adjustment and movement of the device to the area where the trees need to be watered. Move the frame 1 so that the trunk of the tree enters the fixed frame 62 and the water spray frame 64 from the opening. By starting the liquid pump 5, the water in the water tank 2 enters the first hose 4 through the water pipe 3, and then enters the mobile frame 63 from the first hose 4, and then enters the water spray frame 64. The water enters the spray cover 67 through the second hose 65 and the drain pipe 66, and is discharged from the drain hole. The output shaft of the first motor 72 rotates to rotate the gear 73, so that the gear ring 71 rotates with the water spray frame 64, so that part of the spray cover 67 at the water spray frame 64 can be rotated to the side of the tree trunk away from the frame 1, so as to irrigate the area where the tree trunk is away from the frame 1. In this way, it can be ensured that the soil at the root of the tree can be irrigated, so that the irrigation is more uniform, thereby improving the effect of irrigation. While watering, the output shaft of the electric telescopic rod 13 is extended, so that the sliding ring frame 11 is downward The extrusion plate 14 moves downward, and the extrusion plate 14 squeezes the airbag 81, so that the gas inside the airbag 81 enters the through-tube 84 from the sleeve 83, and enters the cavity 611 through the through-tube 84. The gas entering the cavity 611 enters the third hose 612, and then enters the ventilation pipe 613, and finally enters the large pipe 68 through the ventilation pipe 613. Under the action of the gas pressure, the piston 610 moves with the small pipe 69 in the direction away from the first spring 614. The first spring 614 is in a stretched state. Due to the relative movement between the small tube 69 and the large tube 68, the length between the small tube 69 and the large tube 68 changes. In this process, the spray hood 67 can be swung, so that water is sprayed from the spray hood 67 at different angles. In combination with the rotation of the spray rack 64, different positions of the soil around the tree trunk can be irrigated, so that the uniformity of soil irrigation in the area around the tree trunk is further improved, thereby further improving the effect of tree irrigation.

[0047] When the output shaft of the electric telescopic rod 13 is extended, the sliding ring frame 11 moves downward, so that the round tube 91 and the insertion tube 92 move downward, so that the insertion tube 92 is inserted into the soil around the trunk of the tree, so that many small holes can be made in the soil around the trunk, so that the irrigation water can penetrate the soil inside the soil, reduce the surface runoff of the irrigation water, and further improve the irrigation effect. In the process of the insertion tube 92 moving downward and piercing the soil around the trunk of the tree, if the bottom of the insertion tube 92 contacts the root of the tree, the insertion tube 92 and the slide frame 93 slide relative to each other, and the third spring 94 is compressed to prevent the insertion tube 92 from piercing the tree roots and affecting the health of the tree. The water entering the water spray frame 64 enters the water cavity 16 through the leakage pipe 17 and enters the connecting pipe 15. When the insertion tube 92 moves downward and pierces the soil around the trunk of the tree, the water entering the connecting pipe 15 flows into the insertion tube 92, so that part of the water is injected into the soil, which is convenient for the tree roots to absorb water.
