[0016] The present invention provides a tree irrigation device for municipal gardens. It has the following beneficial effects:

[0017] 1. The present invention is provided with an adjusting device. When irrigating, the driving component controls the water delivery pipe to rotate. The rotation of the water delivery pipe drives the irrigation pipe to rotate, increasing the area for irrigating trees by this device. Cooperating with the limiter, the limiting column and the wave groove, the water delivery pipe can move up and down while rotating. The water delivery pipe drives the irrigation pipe to move up and down, raising the sprinkler head, making the arc of the water spray move upward, increasing the radius of the irrigated fan-shaped area, expanding the irrigation range, enabling this device to irrigate more trees, and improving the irrigation efficiency; while the water delivery pipe slides upward, it drives the airbag to move upward as well, and cooperates with the limiting block and the pressing plate to squeeze the airbag, so that the airbag quickly squeezes the gas into the irrigation pipe, pushing out the possible sediment in the sprinkler head, avoiding sediment blocking the sprinkler head and affecting irrigation.

[0018] 2. The present invention is provided with a regulating device. When irrigating, the relative movement of the fixed block and the limiting block drives the first hinge rod and the second hinge rod to rotate, pushing the limiting plate to drive the spring rod to rotate around the valve, thereby driving the valve to rotate, intermittently opening and closing, making the water supply in the irrigation pipe intermittent, reducing the water output of the irrigation water, and avoiding waste of water resources caused by excessive irrigation in the same place; while intermittently supplying water, the cam rotates to push the knocking ring to slide, knocking on the irrigation pipe, pushing out the sediment and other sundries pushed out by the adjusting device when squeezing the airbag, avoiding sediment adhering to the sprinkler head and still blocking the sprinkler head after being wetted by the irrigation water.

[0019] 3. The present invention is provided with a protection device. By monitoring the temperature through a temperature sensor, it is determined whether to start the device. When the temperature is relatively low, the temperature sensor transmits an electrical signal to the controller, causing the controller to control the cylinder to start, push the piston rod to expand and contract, and at the same time cooperate with the limiting rod to drive the clamping rod to rotate, so that the clamping rod repeatedly squeezes the airbag, repeatedly inhaling and extruding the air, accelerating the air circulation speed, accelerating the evaporation of the water in the irrigation pipe, reducing the residue of the irrigation water in the irrigation pipe, and avoiding the freezing of the irrigation water in the irrigation pipe and damaging the irrigation pipe when the temperature is relatively low.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-7, an embodiment of the present invention is: A tree irrigation device for municipal gardens includes a water storage tank 1. Universal wheels 2 are fixed to the bottom surface of the water storage tank 1. A water delivery pipe 3 penetrates through the upper surface of the water storage tank 1, and the penetration part is slidably connected. The water delivery pipe 3 communicates with the water storage tank 1. An irrigation pipe 4 is fixed to the outer wall of the water delivery pipe 3. The irrigation pipe 4 communicates with the water delivery pipe 3. The water delivery pipe 3 transports the irrigation water in the water storage tank 1 into the irrigation pipe 4. Sprayers 5 are fixed to the outer wall of the irrigation pipe 4. The irrigation pipe 4 squeezes out the irrigation water through the sprayers 5 to irrigate the trees around the equipment. The sprayers 5 communicate with the irrigation pipe 4. An adjusting device for conveniently expanding the spraying range is provided on the outer wall of the water delivery pipe 3.

[0030] Among them, the adjusting device includes a driving component 61, a stopper 62, a limiting column 63, a wave groove 64, a limiting block 65, a pressing plate 66, a guide rod 67 and an airbag 68. The driving component 61 is fixedly connected to the upper surface of the water storage tank 1. The driving component 61 is a motor. When irrigation is carried out, the driving component 61 is started, and the output end of the driving component 61 can rotate. The water delivery pipe 3 passes through the driving component 61, and the passing-through part is slidably connected. When the output end of the driving component 61 rotates, it drives the water delivery pipe 3 to rotate. The stopper 62 is fixedly connected to the upper surface of the water storage tank 1. The water delivery pipe 3 passes through the stopper 62, and the passing-through part is in contact. The limiting column 63 is fixedly connected to the inner wall of the stopper 62. The wave groove 64 is opened on the outer wall of the water delivery pipe 3. The outer wall of the limiting column 63 and the inner wall of the wave groove 64 are slidably connected. Since the limiting column 63 on the inner wall of the stopper 62 and the wave groove 64 on the outer wall of the water delivery pipe 3 are slidably connected, when the water delivery pipe 3 rotates, it drives the wave groove 64 to rotate together. When the wave groove 64 rotates, it is slidably connected with the limiting column 63, so that the limiting column 63 slides along the wave groove 64 when sliding. Also, since the stopper 62 is fixed on the upper surface of the water storage tank 1, when the wave groove 64 rotates, it also drives the water delivery pipe 3 to slide up and down. When the water delivery pipe 3 slides up and down, it drives the irrigation pipe 4 to rotate while moving up and down. The irrigation water is sprinkled farther under the action of centrifugal force when rotating. When the irrigation pipe 4 moves up and down, it raises the nozzle 5, so that the spraying arc moves upward, and the radius of the irrigated fan-shaped area increases, expanding the irrigation range. The irrigation pipe 4 passes through the limiting block 65, and the passing-through part is slidably connected. The limiting block 65 is slidably connected to the upper surface of the stopper 62. The pressing plate 66 is fixedly connected to the upper surface of the limiting block 65. The guide rod 67 is fixedly connected to the upper surface of the water delivery pipe 3. The guide rod 67 passes through the pressing plate 66, and the passing-through part is slidably connected. The airbag 68 is fixedly connected to the inner wall of the water delivery pipe 3. When the water delivery pipe 3 slides upward, the airbag 68 on its upper surface also moves upward together. The airbag 68 is communicated with the water delivery pipe 3. Since the limiting block 65 is slidably connected to the upper surface of the stopper 62, when the water delivery pipe 3 slides upward, the limiting block 65 is fixed in the vertical direction. The limiting block 65 is fixed to the pressing plate 66. When the airbag 68 moves upward, it is compressed by the pressing plate 66, and the gas is quickly squeezed into the irrigation pipe 4, so that the gas is discharged through the irrigation pipe 4 and the nozzle 5. When the adjusting device is irrigating, the output end of the driving component 61 rotates to drive the water delivery pipe 3 to rotate, and the water delivery pipe 3 rotates to drive the irrigation pipe 4 to rotate, increasing the area of the equipment for irrigating trees. Cooperating with the stopper 62, the limiting column 63 and the wave groove 64, the water delivery pipe 3 can move up and down while rotating. The water delivery pipe 3 drives the irrigation pipe 4 to move up and down, raising the nozzle 5, so that the spraying arc moves upward, and the radius of the irrigated fan-shaped area increases, expanding the irrigation range, enabling the equipment to irrigate more trees and improving the irrigation efficiency;While the conveying water pipe 3 slides upward, it drives the airbag 68 to move upward as well. In cooperation with the limiting block 65 and the pressing plate 66, the airbag 68 is squeezed, causing the airbag 68 to quickly squeeze the gas into the irrigation pipe 4, pushing out the possible sediment in the nozzle 5, and avoiding sediment blockage of the nozzle 5, which may affect irrigation.

[0031] When this embodiment works: The conveying water pipe 3 conveys the irrigation water in the water storage tank 1 to the irrigation pipe 4. The irrigation pipe 4 squeezes out the irrigation water through the nozzle 5 to irrigate the trees around the equipment. During irrigation, the driving component 61 starts to rotate. When the output end of the driving component 61 rotates, it drives the conveying water pipe 3 to rotate. Since the limiting column 63 on the inner wall of the limiter 62 is slidably connected to the wave groove 64 on the outer wall of the conveying water pipe 3, when the conveying water pipe 3 rotates, it drives the wave groove 64 to rotate together. When the wave groove 64 rotates, it is slidably connected to the limiting column 63, causing the limiting column 63 to slide along the wave groove 64 during sliding. Also, since the limiter 62 is fixed on the upper surface of the water storage tank 1, when the wave groove 64 rotates, it also drives the conveying water pipe 3 to slide up and down. When the conveying water pipe 3 slides up and down, it drives the irrigation pipe 4 to rotate and move up and down at the same time. When the conveying water pipe 3 slides upward, the airbag 68 on its upper surface also moves upward together. Since the limiting block 65 is slidably connected to the upper surface of the limiter 62, when the conveying water pipe 3 slides upward, the limiting block 65 remains fixed in the vertical direction. The limiting block 65 is fixed to the pressing plate 66. When the airbag 68 moves upward, it is compressed by the pressing plate 66, quickly squeezing the gas into the irrigation pipe 4, causing the gas to be discharged through the irrigation pipe 4 and the nozzle 5, pushing out the possible sediment at the nozzle 5. When the conveying water pipe 3 slides downward, it drives the airbag 68 to move downward as well. The airbag 68 is no longer squeezed, causing the airbag 68 to reset.

[0032] Please refer to Figures 1-7, on the basis of the above embodiments, in another embodiment of the present invention, a regulating device for facilitating the control of the water output is provided above the irrigation pipe 4. The regulating device includes a first hinge rod 71, a fixed block 72, a second hinge rod 73, a limiting plate 74, a valve 75, a spring rod 76, a knocking ring 77 and a return spring 78. The upper end of the first hinge rod 71 is hinged to the side wall of the limiting block 65. The irrigation pipe 4 passes through the fixed block 72 and is fixedly connected at the passing-through position. When the irrigation pipe 4 moves upward, it drives the fixed block 72 to move upward as well. The lower end of the second hinge rod 73 is hinged to the upper surface of the fixed block 72. When the fixed block 72 moves upward, it drives the second hinge rod 73 to move upward. The lower end of the first hinge rod 71 and the upper end of the second hinge rod 73 are hinged to each other. The second hinge rod 73 pushes the first hinge rod 71 to rotate, causing the hinge point of the first hinge rod 71 and the second hinge rod 73 to move. The first hinge rod 71 changes from vertical to horizontal, and its hinge point with the second hinge rod 73 moves away from the limiting block 65. A cylinder is fixed to the side wall of the first hinge rod 71. The cylinder passes through the upper end of the second hinge rod 73. The limiting plate 74 is fixedly connected to the end of the cylinder away from the first hinge rod 71. When the hinge point of the second hinge rod 73 and the first hinge rod 71 moves away from the limiting block 65, it drives the limiting plate 74 to move away from the limiting block 65 as well. The valve 75 passes through the irrigation pipe 4 and is rotatably connected at the passing-through position. The spring rod 76 is fixedly connected to the upper surface of the valve 75. The rotation of the spring rod 76 drives the valve 75 to rotate. A sliding groove is formed on the bottom surface of the limiting plate 74. The upper surface of the spring rod 76 and the inner wall of the sliding groove are slidably connected. The limiting plate 74 drives the spring rod 76 to move, and the spring rod 76 rotates around the central axis of the valve 75. Therefore, when the spring rod 76 moves, it also slides along the upper surface of the sliding groove of the limiting plate 74. A cam is fixed to the outer wall of the valve 75. When the valve 75 rotates, it drives the cam to rotate. The irrigation pipe 4 passes through the knocking ring 77 and is slidably connected at the passing-through position. The cam pushes the knocking ring 77 to slide and knock on the irrigation pipe 4. One end of the return spring 78 is fixedly connected to the side wall of the knocking ring 77, and the other end of the return spring 78 is fixedly connected to the side wall of the fixed block 72. When the knocking ring 77 slides and knocks on the irrigation pipe 4, the return spring 78 is stretched. When the valve 75 rotates and closes again, the return spring 78 applies a pulling force to the knocking ring 77 to reset the knocking ring 77. When the regulating device is irrigating, the relative movement between the fixed block 72 and the limiting block 65 drives the first hinge rod 71 and the second hinge rod 73 to rotate, pushing the limiting plate 74 to drive the spring rod 76 to rotate around the valve 75, thereby driving the valve 75 to rotate, intermittently opening and closing, so that intermittent water supply is carried out in the irrigation pipe 4, reducing the water output of the irrigation water and avoiding waste of water resources caused by excessive irrigation at the same place;While intermittently supplying water, the knocking ring 77 is pushed to slide by the rotation of the cam, knocking on the irrigation pipe 4 to push out sundries such as sediment ejected when the regulating device squeezes the airbag 68, preventing sediment from adhering to the nozzle 5 and clogging the nozzle 5 after being wetted by the irrigation water.

[0033] A protection device for preventing the water pipe from freezing in cold weather is provided on the upper surface of the water storage tank 1. The protection device includes a temperature sensor 81, a controller 82, a limiting rod 83, a cylinder 84, a piston rod 85 and a clamping rod 86. The temperature sensor 81 is fixedly connected to the upper surface of the water storage tank 1, and the controller 82 is fixedly connected to the upper surface of the water storage tank 1. The temperature sensor 81 and the controller 82 are electrically connected. When the temperature sensor 81 detects a lower temperature, it transmits an electrical signal to the controller 82. The limiting rod 83 is fixedly connected to the upper surface of the conveying water pipe 3, and the cylinder 84 is fixedly connected to the upper surface of the conveying water pipe 3. The cylinder 84 is electrically connected to the controller 82, and the controller 82 transmits a signal to the cylinder 84 to activate the cylinder 84. The left and right pistons of the cylinder 84 are connected with the piston rod 85. The cylinder 84 pushes the piston rods 85 on both sides to extend. One end of the piston rod 85 away from the cylinder 84 is fixed with a hinge block, and the piston rod 85 drives the hinge block to move. The limiting rod 83 passes through the clamping rod 86 and is slidably connected at the passing position. Since the clamping rod 86 is penetrated by the limiting rod 83, the clamping rod 86 rotates around the limiting rod 83 when moving. The clamping rod 86 is hinged to the side wall of the hinge block. When the hinge block moves, it pushes the clamping rod 86 to move. The two clamping rods 86 rotate and approach each other, squeezing the airbag 68, causing the airbag 68 to push out the air. The cylinder 84 repeatedly contracts the piston rod 85. This protection device judges whether to start the device by the temperature monitoring of the temperature sensor 81. When the temperature is relatively low, the temperature sensor 81 transmits an electrical signal to the controller 82, causing the controller 82 to control the cylinder 84 to start, pushing the piston rod 85 to expand and contract, and at the same time cooperating with the limiting rod 83 to drive the clamping rod 86 to rotate, so that the clamping rod 86 repeatedly squeezes the airbag 68, repeatedly inhaling and squeezing out the air, accelerating the air circulation speed, accelerating the evaporation of the water in the irrigation pipe 4, reducing the residue of the irrigation water in the irrigation pipe 4, and avoiding the irrigation water freezing in the irrigation pipe 4 and freezing the irrigation pipe 4 when the temperature is relatively low.

[0034] During the operation of this embodiment: Since the fixed block 72 is fixed to the outer wall of the irrigation pipe 4, when the irrigation pipe 4 moves upward, the fixed block 72 is driven to move upward as well. When the fixed block 72 moves upward, it drives the second hinge rod 73 to move upward. The second hinge rod 73 pushes the first hinge rod 71 to rotate, causing the hinge point between the first hinge rod 71 and the second hinge rod 73 to move. The first hinge rod 71 changes from vertical to horizontal, and its hinge point with the second hinge rod 73 moves away from the limit block 65, driving the limit plate 74 to also move away from the limit block 65. The limit plate 74 drives the spring rod 76 to move, and the spring rod 76 drives the valve 75 to rotate. Also, since the spring rod 76 rotates around the central axis of the valve 75, when the spring rod 76 moves, it also slides along the upper surface of the sliding groove of the limit plate 74. The valve 75 rotates and opens, allowing the irrigation water to be sprayed normally. When the fixed block 72 moves downward, it drives the second hinge rod 73 to move downward. The second hinge rod 73 pushes the first hinge rod 71 to rotate, causing the hinge point between the first hinge rod 71 and the second hinge rod 73 to move. The first hinge rod 71 changes from horizontal to vertical, and its hinge point with the second hinge rod 73 moves towards the limit block 65, driving the limit plate 74 to also move towards the limit block 65. The limit plate 74 drives the spring rod 76 to move, and the spring rod 76 drives the valve 75 to rotate. Also, since the spring rod 76 rotates around the central axis of the valve 75, when the spring rod 76 moves, it also slides along the upper surface of the sliding groove of the limit plate 74. The valve 75 rotates and closes, stopping the spraying of the irrigation water. When the valve 75 rotates, it drives the cam to rotate, and the cam pushes the knocking ring 77 to slide and knock on the irrigation pipe 4, while stretching the return spring 78.

[0035] When the weather is relatively cold, the irrigation water may freeze, so it is necessary to clean the irrigation water in the irrigation pipe 4 in advance. When the temperature sensor 81 detects a low temperature, it transmits an electrical signal to the controller 82. The controller 82 transmits a signal to the cylinder 84 to activate the cylinder 84. The cylinder 84 pushes the piston rods 85 on both sides to extend. The piston rods 85 drive the hinge blocks to move. When the hinge blocks move, they push the clamping rods 86 to move. Also, since the clamping rods 86 are penetrated by the limiting rods 83, when the clamping rods 86 move, they also rotate around the limiting rods 83. The two groups of clamping rods 86 rotate and approach each other, squeezing the airbag 68, causing the airbag 68 to push out the air. The cylinder 84 repeatedly contracts the piston rods 85, causing the airbag 68 to repeatedly inhale and extrude the air, accelerating the air circulation speed and accelerating the evaporation of the moisture in the irrigation pipe 4.
