[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] like Figures 1-8 As shown, a sprinkler machine of the present invention comprises a mobile support 2 and a towing frame 1, wherein the mobile support 2 is coupled to a connecting support 4, and a sprinkler assembly 3 for sprinkler irrigation is provided on one side of the connecting support 4;

[0035] The connecting support 4 includes a circular ring 44 for slidingly sleeved on the outer wall of the top of the mobile bracket 2. One side of the circular ring 44 is fixedly connected to a first connecting rod 41 for transmitting traction force. A plug-in rod 5 is provided on one side of the towing frame 1. The middle part of the plug-in rod 5 is provided with a sliding channel 51 for connecting with the first connecting rod 41.

[0036] The first connecting rod 41 is connected to a horizontal fixing plate 42 in the middle of the side close to the slide 51 by a fixing bolt. The bottom of the horizontal fixing plate 42 is fixedly connected to a sliding member 43. The sliding member 43 is plugged into the slide 51. Move the first connecting rod 41 upward to separate the sliding member 43 from the slide 51.

[0037] Pushing the connecting support 4 can adjust the sprinkler assembly 3 in the horizontal direction. At this time, the movable bracket 2 does not need to be moved to accelerate the adjustment of the position of the sprinkler assembly 3. When the sprinkler assembly 3 needs to be transported, it is only necessary to buckle the connecting support 4 with the slide 51. By connecting the towing frame 1, the sprinkler assembly 3 can be moved conveniently and quickly.

[0038] When it is necessary to move the sprinkler assembly 3, the sliding member 43 is inserted into the slide 51. During the shipping process, the connecting rod 5 is driven to move by the towing frame 1, thereby pulling the sprinkler assembly 3 to move through the first connecting rod 41. It is convenient and quick. When it reaches the preset position, it can be sprayed directly through the sprinkler assembly 3. When adjustment is required, the first connecting rod 41 is pushed. At this time, the sliding member 43 moves along the slide 51, and the sprinkler assembly 3 moves with the first connecting rod 41 to achieve adjustment of the horizontal position of the sprinkler assembly 3. The connecting rod 5 and the movable bracket 2 can increase the stability of the sprinkler assembly 3 during operation.

[0039] Specifically, the sliding member 43 includes a side plate 433 abutting against the outer wall of the plug rod 5 and a plug plate 431 inserted into the slide channel 51. Both sides of the plug plate 431 are rotatably connected to rotating beads 432, and the rotating beads 432 are in contact with the inner wall of the slide channel 51.

[0040] In the process of pushing the first connecting rod 41, the first connecting rod 41 can drive the sliding member 43 to move synchronously. The sliding member 43 is cooperated with the plug-in rod 5. During this process, the side plate 433 will move along the outer wall of the plug-in rod 5, and the plug-in plate 431 will move along the middle of the slide 51. The coordination of the plug-in plate 431, the side plate 433 and the plug-in rod 5 can increase the stability of the sprinkler assembly 3 during movement.

[0041] At the same time, the first connecting rod 41 can be lifted upwards to drive the plug-in plate 431 and the side plate 433 to move out of the plug-in rod 5, thereby realizing the separation of the movable bracket 2 and the towing frame 1.

[0042] Specifically, a tightening threaded rod is rotated through the top of the circular ring 44, and one end of the tightening threaded rod placed above the circular ring 44 is fixedly connected to a rotating disk 441 for driving the tightening threaded rod to rotate, and one end of the tightening threaded rod placed inside the circular ring 44 is fixedly connected to a friction tightening plate 442 for tightening with the movable bracket 2.

[0043] The setting of the return ring 44 can slide along the outer wall of the mobile bracket 2, thereby driving the sprinkler assembly 3 connected on one side to move synchronously. At this time, the mobile bracket 2 does not need to move, and the mobile bracket 2 can play a good supporting role during use. When the user rotates the rotating disk 441 above the return ring 44, the rotating disk 441 drives the tightening threaded rod to rotate synchronously. At this time, the tightening threaded rod will move in the direction close to the mobile bracket 2, so that the friction tightening piece 442 is tightened against the mobile bracket 2, ensuring the stability of the sprinkler assembly 3 during use. When the sprinkler assembly 3 needs to be adjusted, the rotating disk 441 is rotated in the direction, and the friction tightening piece 442 can be driven to move in the direction away from the mobile bracket 2 through the tightening threaded rod, thereby achieving the purpose of the return ring 44 being able to move along the outer wall of the mobile bracket 2.

[0044] Specifically, the sprinkler assembly 3 includes a mounting seat 33, the top of which is movably connected to a nozzle head 38, the circular ring 44 is fixedly connected to a connecting tripod 35 for supporting the mounting seat 33, and the bottom of the mounting seat 33 is fixedly connected to a water inlet connecting pipe 31.

[0045] During sprinkler irrigation, water enters the mounting seat 33 from the lower end through the water inlet connecting pipe 31, and is then sprayed out through the nozzle head 38. The stability of the nozzle head 38 during the sprinkler irrigation process is ensured by connecting the tripod 35 and the mounting seat 33. When the circular ring 44 is pushed to move, the connecting tripod 35 is driven to move synchronously, thereby driving the mounting seat 33 to move, and the nozzle head 38 is driven to move synchronously through the mounting seat 33 to achieve adjustment of the sprinkler irrigation range.

[0046] Specifically, a storage cylinder 32 for collecting impurities is provided at the bottom of the bent portion of the water inlet connecting pipe 31 , and a control valve 34 for controlling the water pressure of the nozzle head 38 is provided at one end of the nozzle head 38 connected to the mounting seat 33 .

[0047] In the process of water entering the water inlet connecting pipe 31, granular impurities in the water may accumulate at the turning point of the water inlet connecting pipe 31 from the horizontal downward to the upward direction. The impurities are collected by the storage cylinder 32 to avoid the accumulation of impurities, which is conducive to the centralized treatment of impurities. The size of the opening of the nozzle head 38 can be controlled by the setting of the control valve 34, thereby adjusting the water pressure of the sprayed water. When the water pressure increases, the distance of the sprinkler irrigation can be increased.

[0048] The present invention also provides a central support shaft type rotary quantitative conveying device, including a sprinkler machine as described above, wherein the towing frame 1 is fixedly connected to the side support frame 11 on both sides for pipeline quantitative conveying, and a winding roller 13 is rotatably provided in the middle of the side support frame 11, and the outer wall of the winding roller 13 is wound with a water pipe, and an electric control device is provided in the side support frame 11 for controlling the winding of the water pipe, one end of the water pipe is connected to the water inlet connecting pipe 31, and a water inlet pipe 14 is fixedly provided on one side of the side support frame 11, and the water inlet pipe 14 is connected to the water pump.

[0049] During the sprinkler irrigation process, the mobile bracket 2 can be separated from the towing frame 1, and the mobile bracket 2 can be pushed to the preset position. At this time, the water pipe can be quantitatively unfolded by rotating the reeling roller 13, and the length of the water pipe extension can be controlled according to actual needs, so as to ensure that the sprinkler irrigation component 3 can be moved to the preset position, and continuous water supply can be achieved through the water pump connected to the water inlet pipe 14. The side support frame 11 plays a supporting and installation role, and the reeling and releasing of the water pipe can be achieved through the electronic control equipment, which can more accurately control the length of the unfolded water pipe.

[0050] Specifically, one side of the side support frame 11 is fixedly connected to an inclined support plate 12, and a limiting plate 121 is fixedly welded to the inner side of the inclined support plate 12. The limiting plate 121 is tilted, and an L-shaped clamping plate 122 is fixedly connected to the upper surface of the limiting plate 121.

[0051] Both ends of the plug-in rod 5 are fixedly connected with an inclined plug rod 52, and the inclined plug rod 52 is a square tube. The two L-shaped clamping plates 122 are adapted to the two inclined plug rods 52. The outer wall of the inclined plug rod 52 is provided with a wedge-shaped limit block, and the inclined plug rod 52 and the wedge-shaped limit block can be cooperated and inserted in the L-shaped clamping plate 122.

[0052] The tilting plug rod 52 can be inserted between the limit plate 121 and the L-shaped card plate 122 to increase the stability of the plug rod 5. The wedge-shaped limit block can ensure that the plugging is more stable. The tilting plug rod 52 passes through the L-shaped card plate 122 and is provided with a pin hole at one end, which can be inserted into the pin to loosen it. When it needs to be disassembled, the pin can be pulled out and pushed upward with force to separate the tilting plug rod 52 from the L-shaped card plate 122. The two L-shaped card plates 122 can limit the tilting plug rod 52, and the limit plate 121 can play a supporting role to ensure the stability of the tilting plug rod 52.

[0053] Working principle: When the sprinkler needs to be shipped, the inclined plug rod 52 can be inserted between the limit plate 121 and the L-shaped card plate 122, and the connection is fixed by a pin. At the same time, the sliding member 43 is inserted into the slide channel 51 above the plug rod 5. By rotating the rotating disk 441, the friction clamping plate 442 can be driven to move toward the direction of the mobile bracket 2 by tightening the threaded rod, and tightened with the mobile bracket 2, so that the stability of the sprinkler assembly 3 can be guaranteed during the movement.

[0054] Before irrigation, connect the water pipe to the water inlet connecting pipe 31. A water pump connected to the water inlet pipe 14 continuously supplies water. Water enters the water pipe through the water inlet pipe 14 and then enters the water inlet connecting pipe 31. Before irrigation, the extension of the water pipe is controlled by the electronic control device. The tilting rod 52 is pulled out from the limit plate 121, and the mobile bracket 2 is pushed to the preset position. The water pump is turned on to start the irrigation operation. During the irrigation process, the tilting rod 52 and the mobile bracket 2 serve as support, and the mobile bracket 2 can be pushed to drive the irrigation assembly 3 to move while irrigation is carried out.

[0055] When it is necessary to move the sprinkler assembly 3, the sliding member 43 is inserted into the slide 51. During the shipping process, the connecting rod 5 is driven to move by the towing frame 1, thereby pulling the sprinkler assembly 3 to move through the first connecting rod 41. It is convenient and quick. When it reaches the preset position, it can be sprayed directly through the sprinkler assembly 3. When adjustment is required, the first connecting rod 41 is pushed. At this time, the sliding member 43 moves along the slide 51, and the sprinkler assembly 3 moves with the first connecting rod 41 to achieve adjustment of the horizontal position of the sprinkler assembly 3. The connecting rod 5 and the movable bracket 2 can increase the stability of the sprinkler assembly 3 during operation.

Those skilled in the art should understand that the present invention is not limited to the above-described embodiments.
