Technical Field

[0001] The utility model relates to the technical field of water conservancy engineering, in particular to an irrigation device of a water conservancy engineering mechanism. Background Art

[0002] An irrigation device with an adjustment mechanism for water conservancy projects disclosed on a Chinese patent website (Announcement No.: CN217089012U) solves the technical problems that the existing irrigation devices have a relatively simple structure, a relatively single function, often do not have an adjustment function, cannot adjust the irrigation head according to the on-site conditions during actual use, and have certain defects in use, but still have the following problems:

[0003] In actual use, the structure of the threaded rod and the threaded sleeve is used for threaded connection, and the threaded sleeve is driven to rise and fall by the rotation of the threaded rod. After long-term use, the friction between the threaded rod and the threaded sleeve increases, which causes energy loss and reduced efficiency. Excessive friction will also increase the motor load, increase energy consumption and reduce system life. Long-term friction and wear will cause the shape of the threaded rod and the threaded sleeve to change, which will affect their accuracy and lifting performance. At the same time, excessive friction will cause vibration and noise, which will interfere with the surrounding environment. This not only affects the quietness of the working environment, but may also cause discomfort to personnel, making it inconvenient to use. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-Figure 5 An irrigation device for a water conservancy engineering organization includes a chassis 1 and an irrigation device 2. The irrigation device 2 is installed on the surface of the chassis 1. A lifting mechanism is installed on the surface of the chassis 1. The lifting mechanism includes a threaded rod 3 and a threaded sleeve 31. An oil box 32 is fixedly connected to the inner wall surface of the upper end of the threaded sleeve 31. The upper and lower surfaces of the oil box 32 are both opened. A self-sealing plug 33 is installed on the inner wall of the lower end opening of the oil box 32.

[0026] In order to drill out the lubricating oil, the inner wall of the threaded sleeve 31 is threadedly sleeved with the surface of the threaded rod 3, and a drill bit 34 is fixedly connected to the upper surface of the threaded rod 3. An oil extraction groove 341 is provided on the upper end surface of the drill bit 34, and an oil throwing groove 342 is provided on the outer wall surface of the lower end of the drill bit 34. The interior of the oil throwing groove 342 is connected to the interior of the oil extraction groove 341. The drill bit 34 is located directly below the oil box 32, so that the drill bit 34 can drill into the oil box 32 from below.

[0027] In order to drive the threaded rod 3, a driving motor 35 is installed inside the chassis 1. The output shaft of the driving motor 35 is fixedly connected to the lower surface of the threaded rod 3. The driving motor 35 is used to provide power for the rotation of the threaded rod 3, so as to facilitate driving the threaded rod 3. A mounting cylinder 36 is fixedly connected to the upper surface of the chassis 1. A limiting groove is provided on the inner wall of the mounting cylinder 36. A limiting rod 37 is slidably connected to the inner wall of the limiting groove. The threaded sleeve 31 is movably installed by using the mounting cylinder 36, so as to facilitate avoiding accidental dislocation of the threaded sleeve 31. The side wall surface of the limiting rod 37 is fixedly connected to the outer wall surface of the threaded sleeve 31. The threaded sleeve 31 is located on the inner side of the mounting cylinder 36 and is wrapped by the mounting cylinder 36, so as to facilitate protecting the connection between the threaded sleeve 31 and the threaded rod 3.

[0028] By installing an oil box 32 and a drill bit 34 in a conventional lifting mechanism, and injecting a proper amount of lubricating oil into the oil box 32, when the threaded sleeve 31 is reset, the oil box 32 is inserted into the surface of the drill bit 34, so that part of the lubricating oil enters the oil extraction groove 341, and then enters between the threaded sleeve 31 and the threaded rod 3 through the oil throwing groove 342 for lubrication. As the threaded sleeve 31 continues to fall, the upper end opening surface of the oil extraction groove 341 is higher than the liquid level of the lubricating oil, thereby avoiding the waste of lubricating oil and facilitating the long-term use of the lifting mechanism.

[0029] The upper surface of the threaded sleeve 31 is fixedly connected to a hinged seat 4, and the surface of the hinged seat 4 is fixedly connected to the nozzle end of the irrigation equipment 2 through a screw. The hinged seat 4 is used to connect the nozzle end of the irrigation equipment 2 and the threaded sleeve 31, so that the threaded sleeve 31 can drive the nozzle end of the irrigation equipment 2.

[0030] Working principle:

[0031] When in use, the driving motor 35 is started, and the driving motor 35 drives the threaded rod 3 to rotate. The threaded sleeve 31 rises under the action of the threaded rod 3 and the limit rod 37. The threaded sleeve 31 drives the oil box 32 to separate from the surface of the drill bit 34. Part of the lubricating oil in the oil box 32 enters the oil extraction groove 341, and then enters between the threaded sleeve 31 and the threaded rod 3 through the oil throwing groove 342 for lubrication. The self-sealing plug 33 is closed, and the threaded sleeve 31 drives the nozzle of the irrigation device 2 to rise.

[0032] After use, the driving motor 35 drives the threaded rod 3 to rotate in the opposite direction, the threaded sleeve 31 is reset, and the oil box 32 is inserted into the surface of the drill bit 34. As the threaded sleeve 31 continues to fall, the upper opening surface of the oil groove 341 is higher than the liquid level of the lubricating oil, and the lubricating oil in the oil box 32 stops being discharged.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
