If it is necessary to repel insects for the plants, add the medicine liquid into the medicine tank 107, open the valve 108 to introduce the medicine liquid into the irrigation box 103, and then start the motor 201. The motor 201 drives the rotating rod 202 connected to its output end to rotate.

[0026] When it is necessary to water the pomelo plants of different heights, start the motor 2 302 , which drives the threaded rod 303 connected to its output end to rotate. The rotation of the threaded rod 303 drives the nut 304 threadedly connected to it to rise and fall along the direction of the threaded rod 303 , thereby achieving height adjustment of the nozzle 415 .

[0027] like Figure 4 , Figure 5 As shown, the amplitude adjustment component 4 includes two connecting plates 401, the opposite side walls of the two connecting plates 401 are respectively fixedly connected to the opposite sides of the front and rear nuts 304, the tops of the two connecting plates 401 are fixedly connected to the fixing frames 402, the opposite sides of the two fixing frames 402 are fixedly connected to the motor three 403, the output shaft of the motor three 403 passes through the inner wall of the fixing frame 402 and is connected with a concave slide groove 409, the outer wall of the output shaft of the motor three 403 is slidably connected with a sliding sleeve 404, the upper end of the sliding sleeve 404 is rotatably connected with an L-shaped connecting rod 408 through a provided protruding block, and the L-shaped connecting rod 408 is rotatably connected to the L-shaped connecting rod 408.

[0028] like Figure 4 , Figure 5 As shown, the amplitude adjustment component 4 also includes a threaded connection block 407, the right side wall of the threaded connection block 407 is fixedly connected to the left side wall of the fixed frame 402, the inner wall of the threaded connection block 407 is threadedly connected with a screw rod 405, and a rotating handle is provided at one end of the screw rod 405 close to the pouring box 103, and a limit plate 406 is fixedly connected to the end of the screw rod 405 away from the pouring box 103, and the outer wall of the limit plate 406 is clamped on the inner wall of the sliding sleeve 404, and the left and right ends of the cylindrical slider 410 respectively penetrate the left and right outer walls of the rotating seat 411, and the outer wall of the upper cylindrical slider 410 is slidably connected to the inner wall of the L-shaped connecting rod 408, and the left and right ends of the upper cylindrical slider 410 are both provided with limit nuts, and the side wall of the nozzle 415 is connected to the water hose 112 through the set water pipe.

[0029] When it is necessary to adjust the nozzle 415 within a certain range to increase the watering range, first rotate the rotating handle set at the end of the screw rod 405 to rotate the screw rod 405. Since the screw rod 405 is threadedly connected to the threaded connecting block 407, the screw rod 405 will move forward and backward. The movement of the screw rod 405 drives the limit plate 406 fixedly connected thereto to move forward and backward. The movement of the limit plate 406 drives the sliding sleeve 404 clamped thereto to move forward and backward on the output shaft of the motor 3 403. The movement of the sliding sleeve 404 drives the L-shaped connecting rod 408 rotatably connected thereto to rotate. Since the right-angle bend of the L-shaped connecting rod 408 is rotatably connected to the concave sliding groove 409, when the sliding sleeve 404 moves, the cylindrical slider 410 will be in the concave sliding groove 409. 09 slides inside, the cylindrical slider 410 slides and drives the rotating seat 411 fixedly connected thereto to move. When the cylindrical slider 410 moves to the upper end of the concave slide groove 409, the irrigation range is at its largest. After adjusting the irrigation range, start the motor three 403, and the output shaft of the motor three 403 will rotate. The output shaft of the motor three 403 rotates to drive the concave slide groove 409 fixedly connected thereto to rotate. The rotation of the concave slide groove 409 drives the rotating seat 411 slidably connected thereto to rotate. The rotation of the rotating seat 411 drives the steering frame 413 to swing left and right, thereby driving the cross steering block 414 rotatably connected thereto to swing left and right, and further driving the nozzle 415 to swing left and right, thereby realizing the adjustment of the irrigation range and improving the practicality of the device.

[0030] The following is a detailed description of the working principle of the sprinkler irrigation device in the pomelo plantation.

[0031] like Figure 1-5 As shown, when in use, first add water into the irrigation box 103 through the water injection pipe 106. If it is necessary to repel insects to the plants, add the medicine liquid into the medicine tank 107, open the valve 108 to introduce the medicine liquid into the irrigation box 103, and then start the motor 201. The motor 201 drives the rotating rod 202 connected to its output end to rotate. The rotation of the rotating rod 202 drives a plurality of stirring rods 203 fixedly connected to it to rotate, so as to fully stir the medicine liquid and water.

[0032] When it is necessary to water the pomelo plants of different heights, start the motor 2 302 , which drives the threaded rod 303 connected to its output end to rotate. The rotation of the threaded rod 303 drives the nut 304 threadedly connected to it to rise and fall along the direction of the threaded rod 303 , thereby achieving height adjustment of the nozzle 415 .

[0033] When it is necessary to adjust the nozzle 415 within a certain range to increase the watering range, first rotate the rotating handle set at the end of the screw rod 405 to rotate the screw rod 405. Since the screw rod 405 is threadedly connected to the threaded connecting block 407, the screw rod 405 will move forward and backward. The movement of the screw rod 405 drives the limit plate 406 fixedly connected thereto to move forward and backward. The movement of the limit plate 406 drives the sliding sleeve 404 clamped thereto to move forward and backward on the output shaft of the motor 3 403. The movement of the sliding sleeve 404 drives the L-shaped connecting rod 408 rotatably connected thereto to rotate. Since the right-angle bend of the L-shaped connecting rod 408 is rotatably connected to the concave sliding groove 409, when the sliding sleeve 404 moves, the cylindrical slider 410 will be in the concave sliding groove 409. 09 slides inside, the cylindrical slider 410 slides and drives the rotating seat 411 fixedly connected thereto to move. When the cylindrical slider 410 moves to the upper end of the concave slide groove 409, the irrigation range is at its largest. After adjusting the irrigation range, start the motor three 403, and the output shaft of the motor three 403 will rotate. The output shaft of the motor three 403 rotates to drive the concave slide groove 409 fixedly connected thereto to rotate. The rotation of the concave slide groove 409 drives the rotating seat 411 slidably connected thereto to rotate. The rotation of the rotating seat 411 drives the steering frame 413 to swing left and right, thereby driving the cross steering block 414 rotatably connected thereto to swing left and right, and further driving the nozzle 415 to swing left and right, thereby realizing the adjustment of the irrigation range and improving the practicality of the device.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
