[0020] Example 1 Reference Figure 1-3 This is the first embodiment of the present invention, employing the following technical solution: A base plate 1 is provided, a handle 11 is fixedly installed on the rear side of the top of the base plate 1, a water tank 2 is fixedly installed on the rear side of the top of the base plate 1, a water pump 23 is fixedly connected to the bottom of the front side of the water tank 2, a water pump 24 is fixedly connected to the input end of the water pump 23, and the end of the water pump 24 away from the water pump 23 is fixedly connected to the bottom of the water tank 2; a telescopic hose 5 is fixedly connected to the output end of the water pump 23; a swing spray mechanism is also provided, which is located on the top of the base plate 1 and is used for uniform irrigation of the garden greenery; a drive mechanism is located on the top of the water tank 2 and is used to drive the swing spray mechanism to perform swing spraying; a height adjustment mechanism is located above the swing spray mechanism and is used to adjust the spraying height; universal wheels 12 are fixedly installed at the four corners of the bottom of the base plate 1; and stirring blades 211 are fixedly installed at the bottom and middle of the stirring shaft 21.

[0021] Specifically, the water tank 2 is used to store irrigation water and nutrient solution. By starting the drive mechanism, the stirring shaft 21 and the stirring blades 211 fixed on the surface of the stirring shaft 21 are driven to rotate, thereby uniformly stirring the irrigation water and nutrient solution inside the water tank 2. The water pump 23 draws water from the bottom of the water tank 2 through the water pump pipe 24, and then the stirred irrigation water and nutrient solution are irrigated to the garden through the telescopic hose 5 fixed to the output end of the water pump 23. The casters 12 make it easy for the base plate 1 to be moved and sprayed for irrigation under the action of the handle 11, which facilitates the overall transfer of the work.

[0022] Example 2 The second embodiment of this utility model adopts the following technical solution: the driving mechanism includes a stirring shaft 21, a base 221, a bevel gear 3, and a transmission shaft 32. The bottom of the base 221 is fixedly installed on the top of the water tank 2, and a motor 22 is fixedly installed on the top of the base 221. The stirring shaft 21 is located inside the water tank 2, and one end of the stirring shaft 21 is fixedly installed with the output end of the motor 22. The bevel gear 3 is fixedly installed on the top of the stirring shaft 21 and located below the base 221. A fixing frame 321 is fixedly installed on the front side of the top of the water tank 2. The transmission shaft 32 is rotatably installed inside the fixing frame 321, and a bevel gear 31 is fixedly installed on the end of the transmission shaft 32 near the motor 22. The bevel gear 31 meshes with the bevel gear 3. A drive arm 33 is fixedly installed on the end of the bevel gear 31 away from the motor 22.

[0023] Specifically, by activating bevel gear 3, the stirring shaft 21 is driven to rotate. Since bevel gear 3 is fixed to the stirring shaft 21, bevel gear 3 rotates synchronously with the stirring shaft 21. Bevel gear 31 meshes with bevel gear 3, causing bevel gear 3 to drive bevel gear 31 to rotate. In turn, bevel gear 31 drives the transmission shaft 32 to rotate. The fixed frame 321 provides rotational support for the transmission shaft 32, thereby driving the drive arm 33 to rotate synchronously through the transmission shaft 32.

[0024] Example 3 The third embodiment of this utility model adopts the following technical solution: the oscillating water spraying mechanism includes a water spraying component, a limiting block 42, a bracket 44, and a fixing block 441. A connecting rod 4 is fixedly installed on the side of the driving arm 33 away from the transmission shaft 32. A swing ring 41 is fixedly installed on the end of the connecting rod 4 away from the driving arm 33. A limiting groove is formed inside the limiting block 42, and the swing ring 41 is movably engaged with the limiting groove. Fixing members 43 are fixedly installed on both the left and right sides of the limiting block 42. The top of the limiting block 42 is rotatably installed with the bracket 44 through the fixing members 43. The side of the bracket 44 away from the limiting block 42 is rotatably installed with the transmission shaft 32. A first support column 442 is fixedly installed on the front side of the bottom of the bracket 44, and the bottom of the first support column 442 is fixedly installed with the base plate 1. A second support column 443 is fixedly installed on the rear side of the bottom of the bracket 44, and the bottom of the second support column 443 is fixedly installed with the base plate 1. The fixing block 441... 41 is fitted at the bottom of the rear side of the bracket 44, and the rear side of the fixing block 441 is fixedly installed with the water tank 2. The water spraying assembly is set above the limiting block 42 and is used to spray water on the garden greenery. The water spraying assembly includes a water spray pipe 51. The water spray pipe 51 is fixedly connected to the end of the telescopic hose 5 away from the water pump 23. Several sets of water spray probes 511 are fixedly connected at equal distances horizontally on the front side of the water spray pipe 51. The height adjustment mechanism includes an adjustment rod 61. The adjustment rod 61 passes through the limiting block 42 and is fixedly installed with the swing ring 41. The adjustment rod 61 is rotatably engaged with the limiting block 42. A fixing ring 6 is slidably fitted at the bottom of the adjustment rod 61, and the fixing ring 6 is fixedly installed with the rear side of the water spray pipe 51. Several sets of positioning holes 611 are arranged at equal distances longitudinally on the adjustment rod 61. Bolts 62 are threadedly connected to the surface of the fixing ring 6. The bolts 62 pass through the positioning holes 611 and are inserted into the adjustment rod 61.

[0025] Specifically, the rotation of the drive arm 33 causes the connecting rod 4 to rotate accordingly. The connecting rod 4 then drives the swing ring 41 to rotate within the limiting groove of the limiting block 42. During the rotation of the connecting rod 4, the fixing member 43 limits its rotation, allowing the limiting block 42 to flip up and down. This flipping of the limiting block 42 then causes the water spray assembly and height adjustment mechanism to flip as well. The water spray pipe 51 can then adjust its height according to the height adjustment mechanism, achieving height adjustment for sprinkler irrigation. Furthermore, the water spray pipe 51 drives the connected water spray probe 511 to adjust its height accordingly. Simultaneously, after the telescopic hose 5 delivers irrigation liquid, it drives the water spray probe 511 to spray the garden. For forest crops, the adjusting rod 61 can be twisted by the torsion of the swing ring 41, and then the bolt 62, after passing through the fixed ring 6, synchronously drives the water spray pipe 51 fixed to the fixed ring 6 to twist. At this time, the water spray pipe 51 can follow the rotation of the limit block 42 and the torsion of the swing ring 41 to achieve a large-area spraying operation. When the height needs to be adjusted, the bolt 62 can be rotated to separate from the positioning hole 611 to adjust the height of the fixed ring 6. After adjusting to the required height, the bolt 62 is twisted to pass through the fixed ring 6 and extend into the positioning hole 611 to fix the height of the fixed ring 6, so that the bolt 62, the fixed ring 6 and the adjusting rod 61 form a torsionable whole.

[0026] Working principle: The operator can move the device flexibly and quickly adjust the irrigation position by pushing the handle 11 and the casters 12 fixed at the four corners of the base plate 1. At the same time, the water tank 2 can be pre-filled with irrigation water. If it is necessary to improve crop nutrients, nutrient solution can be added at the same time to prepare for subsequent irrigation operations. Once the device is moved to the target irrigation area, the motor 22 in the drive mechanism is started first. The output end of the motor 22 is directly and fixedly connected to the stirring shaft 21 that extends into the water tank 2. After starting, the stirring shaft 21 is driven to rotate at high speed. Since stirring blades 211 are fixedly installed at the bottom and middle of the stirring shaft 21, the rotating stirring blades 211 will fully stir the irrigation water and nutrient solution in the water tank 2, avoid nutrient solution sedimentation, ensure uniform concentration of irrigation medium, and prevent nutrient imbalance during local irrigation from affecting crop growth. While the motor 22 drives the stirring shaft 21, the bevel gear 3 fixedly installed on the top of the stirring shaft 21 rotates synchronously with the stirring shaft 21. The drive shaft 32 is rotatably installed in the fixed frame 321 on the front side of the top of the water tank 2. The bevel gear 31 is fixed at the end of the drive shaft 32 near the motor 22, and the bevel gear 31 meshes precisely with the bevel gear 3. The bevel gear 3 drives the bevel gear 31 to rotate through the meshing relationship. The drive shaft 32 rotates stably under the support of the fixed frame 321. The drive arm 33 fixed at the end away from the motor 22 moves in a circle with the drive shaft 32, converting the lateral rotation power into the linkage power required by the subsequent swing mechanism. When the drive arm 33 rotates, it drives the connecting rod 4 fixed at its end to move synchronously. The end of the connecting rod 4 away from the drive arm 33 is fixed to the swing ring 41, which in turn pulls the swing ring 41 to slide back and forth in the limiting groove inside the limiting block 42. The limiting block 42 is rotatably connected to the bracket 44 through the fixing parts 43 on the left and right sides. The bracket 44 is fixed to the base plate 1 through the support column 1 442 and support column 2 443 at the bottom. The bottom rear side of the bracket 44 is also connected to the water tank 2 through the fixing block 441, which further improves the support stability. The sliding of the swing ring 41 will generate a flipping force on the limiting block 42, causing the limiting block 42 to flip up and down around the rotation connection point between the fixing part 43 and the bracket 44. The flipping of the limiting block 42 directly drives the height adjustment mechanism and the water spray assembly above it to flip synchronously, thereby expanding the irrigation coverage of the water spray probe 511. After the stirring shaft 21 completes the homogenization of the irrigation water, the water pump 23 at the bottom front of the water tank 2 is started. The water pump 23 draws the homogenized irrigation medium from the bottom of the water tank 2 through the water pipe 24 fixed at the input end, and then transports the medium to the water spray pipe 51 of the water spray assembly through the telescopic hose 5 fixed at the output end. The multiple sets of water spray probes 511 connected horizontally and equidistantly at the front of the water spray pipe 51 will evenly spray the irrigation medium onto the surface of the garden greening crops. Combined with the reciprocating motion of the swing mechanism, the effect of uniform irrigation is achieved. When it is necessary to adjust the spray height, first rotate the bolt 62 on the surface of the fixing ring 6 so that the bolt 62 is aligned with the adjusting rod. The positioning hole 611 on 61 is separated, releasing the locking between the fixing ring 6 and the adjusting rod 61; the fixing ring 6 slides up and down, driving the water spray pipe 51 to rise and fall synchronously until the water spray probe 511 reaches the target spraying height; the bolt 62 is rotated again, so that the bolt 62 passes through the fixing ring 6 and is inserted into the positioning hole 611 at the corresponding height of the adjusting rod 61, and the fixing ring 6 and the adjusting rod 61 are locked again. At this time, the adjusting rod 61, the fixing ring 6, and the bolt 62 form a whole that can be twisted with the swing ring 41, which not only ensures the height is fixed, but also does not affect the water spray assembly to follow the reciprocating rotation of the swing mechanism, and finally achieves precise irrigation with adjustable height and swing spray.

[0027] In summary, by incorporating a base plate, handle, water tank, water pump, water pipe, telescopic hose, swing spray mechanism, drive mechanism, and height adjustment mechanism, the system achieves flexibility, automation, and precision in garden and greening irrigation. It solves the problems of traditional buried sprinklers having many dead angles and manual hand-held water pipes being physically demanding and inefficient, thus failing to meet the needs of automation and height adjustment.
