The spray barrel 31 continues to rotate, and the limiting rod 54 will be driven by the elastic force of the bottom positioning spring 53 to enter the limiting hole 56 of the spray barrel 31 for fixation, thereby changing the spray direction of the spray hole 396 on the outer wall of the spray barrel 31. When the spray angle is more perpendicular to the axis of the mounting seat 22, the greater the force on the mounting seat 22, and the faster the rotation speed of the mounting seat 22 itself, the faster the rotation speed, the wider the spray range, and the overall work efficiency is improved.

[0042] How it works

[0043] In actual use, the multiple spray barrels 31 are evenly distributed around the mounting seat 22. The liquid flows from the liquid storage machine 1 through the telescopic cylinder 21 into the multiple spray barrels 31 and is sprayed out from the spray hole 396 under the action of the water pump. The spray direction of the spray barrel 31 is at a certain angle to the axis of the mounting seat 22. The multiple spray barrels 31 can spray at the same time and drive the mounting seat 22 at one end to rotate around the axis of the telescopic cylinder 21. The spray coverage is more uniform and the state of the spray can be changed. The fineness of the spray is adjusted. There are multiple groups of spray holes 396 of different sizes, which can be adjusted by pushing the push block. 493, drives the motion column 491 at the bottom of the push block 493 to squeeze the return spring 48 at one end, and the ratchet 492 at the top of the push block 493 disengages the ratchet groove 43 on the inner wall of the mounting ring 42, and the rotating seat 44 is able to rotate in the mounting ring 42. Rotating the rotating seat 44 causes the rotating seat 44 to rotate around its own axis, and the rotating seat 44 moves and drives the winding roller 494 at the bottom to rotate around its own axis. The winding roller 494 rotates and reels the multiple groups of pull ropes 495 on the surface. The pull ropes 495 drive the motion seat 391 at one end to move along the axis of the spray barrel 31. During the movement of the motion seat 391, The position of the guide hole 395 for connecting the liquid in the liquid storage machine 1 will be misaligned with the position of the spray hole 396 on the surface of the spray barrel 31, and the remaining parts of the moving seat 391 will cover the original spray hole 396. When the guide hole 395 continues to move with the moving seat 391, the guide hole 395 will coincide with the position of the next spray hole 396. The aperture size and number of the spray holes 396 are different, so as to adjust the state of liquid spraying. The device can adjust the spray coverage area, rotate multiple spray barrels 31, so that the spray barrels 31 rotate around the axis of the connecting window 51, and the inner wall of the spray barrel 31 is squeezed. Press the limit rod 54 so that the limit rod 54 enters the third mounting groove 52 at the bottom. The spray barrel 31 continues to rotate, and the limit rod 54 will be driven by the elastic force of the bottom positioning spring 53 to enter the limit hole 56 of the spray barrel 31 for fixation, thereby changing the spray direction of the spray hole 396 on the outer wall of the spray barrel 31. When the spray angle is more perpendicular to the axis of the mounting seat 22, the greater the force on the mounting seat 22, and the faster the rotation speed of the mounting seat 22 itself, the wider the range of the spraying and the larger the coverage area. It has a uniform spraying effect that is beneficial to vegetation growth.
