DETAILED DESCRIPTION

[0028] Example 1: Reference Figure 1-Figure 6, an agricultural plant protection machinery high-efficiency water-saving irrigation device, comprising a frame 1, a water tank 2, a water pump and a nozzle 401, shock-absorbing frames 7 are installed at the four corners of the bottom of the frame 1, and wheels 8 are arranged on the shock-absorbing frames 7, and a buffer assembly 5 connected between the frame 1 and the water pipe 4 is also included; the water tank 2 and the water pump are fixed to the top of the frame 1, the water inlet end of the water pump is connected to the water tank 2, and water pipes 4 extending horizontally outward are arranged on both sides of the water tank 2, and the nozzle 401 is installed at the end of the water pipe 4 away from the water tank 2, and a connecting hose 6 is connected between the end of the water pipe 4 away from the nozzle 401 and the water outlet end of the water pump; the buffer assembly 5 is provided with limit frames 9 located on both sides of the water pipe 4, and the limit frames 9 are arranged near the water pipe 4 and At the position where the connecting hose 6 is connected, the limit frame 9 is vertically extended and installed between the limit frame 9 and the frame 1. A slider 11 is connected to the limit sliding in the limit frame 9. A vertically placed limit rod 10 is installed in the middle position of the limit frame 9. A sliding hole slidably connected to the limit rod 10 is opened on the top of the slider 11. A spring 12 is connected between the bottom of the slider 11 and the limit frame 9. The outer walls of both sides of the water pipe 4 are fixedly connected to the slider 11; the buffer component 5 is also provided with a connecting frame 13, which is fixedly installed between the two limit frames 9, and a connecting cavity is arranged in the connecting frame 13. The connecting hose 6 is connected to the side of the connecting cavity away from the water pipe 4, and a frame cover 15 is arranged on the side of the connecting frame 13 close to the water pipe 4. The frame cover 1 5 is provided with a through hole 151, which extends upward from the middle position of the frame cover 15; the end of the water pipe 4 is in sliding contact with the outer wall of the frame cover 15, and a vertically extending sealing plate 14 is fixed to the outer wall of the water pipe 4, and the top and bottom ends of the sealing plate 14 both extend outward from the frame cover 15, and the sealing plate 14 is in sliding contact with the outer wall of the frame cover 15. In a normal placement state, half of the end of the water pipe 4 is connected with the through hole 151, and the lower part of the end of the water pipe 4 is in contact with the outer wall of the frame cover 15, and the spraying operation of the sprinkler 401 is realized through the connection of the connecting hose 6, the connecting cavity, the through hole 151 and the water pipe 4; when the frame 1 as a whole encounters bumps and ups and downs, the slider 11 and the spring 12 are slidable relative to the limit frame 9 The water pipe 4 is arranged to be vertically displaced relative to the limit frame 9 and the connection frame 13, so that the position of the water pipe 4 in the vertical direction can be repaired auxiliaryly when the frame 1 rises and falls: when the water pipe 4 is displaced upward relative to the connection frame 13 and the frame 1, the connection area between the water pipe 4 and the through hole 151 becomes larger, thereby increasing the water volume and flow rate in the water pipe 4, so that the water spraying intensity of the nozzle 401 increases when it moves upward; when the water pipe 4 moves downward relative to the connection frame 13 and the frame 1, the connection area between the water pipe 4 and the through hole 151 decreases, so as to reduce the water volume and flow rate in the water pipe 4, so that the water spraying intensity of the nozzle 401 decreases when it moves downward; and other positions are blocked by the sealing plate 14 during the displacement of the water pipe 4 relative to the connection frame 13;

[0029] Therefore, when the road surface is bumpy and the frame 1 is caused to rise and fall during the overall movement, the water pipe 4 is moved relative to the frame 1 by the spring 12 to repair the position, and the water volume is adjusted during the relative displacement of the water pipe 4 to repair the water spraying volume, thereby improving the uniformity of sprinkler irrigation and the water-saving effect during the continuous movement.

[0030] In the present invention, reference is made to Figure 1-Figure 6 A plurality of through holes 152 are provided on the side wall of the frame cover 15 below the through hole 151. The through holes 152 correspond to the port positions of the water pipe 4. The apertures of the through holes 152 gradually decrease from top to bottom, so that when the water pipe 4 moves downward relative to the connecting frame 13, it is still possible to realize water injection and sprinkler irrigation by utilizing the connection with the through holes 152. Moreover, as the water pipe 4 moves downward relatively, the inner diameter of the corresponding through hole 152 decreases, and the amount of water is reduced. While realizing the above-mentioned water amount change of the water pipe 4, the space for the water pipe 4 to be continuously connected and displaceable in the vertical direction is increased, thereby further improving the effect of water-saving irrigation operations.

[0031] In the present invention, reference is made to Figure 1-Figure 6 A motor 16 is installed at a position corresponding to the buffer assembly 5 on the top of the frame 1, and the output shaft of the motor 16 extends vertically upward. The output shaft of the motor 16 is installed with a horizontally placed turntable 17, and the bottom end of the limit frame 9 is fixed to the top of the turntable 17, so that the motor 16 drives the turntable 17, the limit frame 9 and the water pipe 4 to rotate, and the water pipe 4 can be adjusted to be tilted for use, and can be rotated and stored above the frame 1 when no irrigation operation is performed.

[0032] In the present invention, reference is made to Figure 1-Figure 6 A mounting frame 3 is fixed on the top of the frame 1 at the periphery of the water tank 2. The mounting frame 3 is used to limit the water tank 2 to ensure the stability of the water tank 2. A pressing block 18 is installed at the position corresponding to the turntable 17 on the outside of the mounting frame 3. The pressing block 18 is in sliding contact with the top of the turntable 17, so that the pressing block 18 limits one side of the top of the turntable 17. On the one hand, the stability of the turntable 17 and the limiting frame 9 is improved when the turntable 17 rotates. On the other hand, when the sprinkler irrigation operation is performed, the water pipe 4 extends outward from the frame 1, and the pressing block 18 is used to limit the top of the turntable 17 on the other side to improve the stability of the turntable 17 and the water pipe 4 during the long-term sprinkler irrigation process, and reduce the load of the drive motor 16 to extend the service life of the equipment, and effectively avoid the water pipe 4 from tilting downward to affect the uniformity of sprinkler irrigation.

[0034] In the present invention, reference is made to Figure 1-Figure 7 A vertically placed connecting rod 22 is arranged below the water pipe 4, and the bottom end of the connecting rod 22 is fixed to the outer wall of the wheel frame 20, and an elastic pull rope 23 is installed between the top of the connecting rod 22 and the bottom of the water pipe 4, and a connecting roller 24 is rotatably arranged at a position corresponding to the elastic pull rope 23 on the frame 1, and the elastic pull rope 23 is slidably wound on the connecting roller 24, and the elastic pull rope 23 connected to the connecting rod 22 is vertically downward, and the elastic pull rope 23 connected to the water pipe 4 is vertically downward. When the wheel frame 20 encounters bumps and rises and falls relative to the frame 1, the elastic pull rope 23 can be pulled to make the water pipe 4 rise and fall in the opposite direction, that is, when the road surface bulges upward, the water pipe 4 is displaced slightly downward, and when the road surface is sunken downward, the water pipe 4 is displaced slightly downward, so as to improve the vertical displacement repair operation effect in the mobile sprinkler irrigation process, thereby further improving the uniformity and water-saving effect of the sprinkler irrigation operation.
