A first nut 406 is threadedly connected to the outer wall of the first lead screw 405. One end of a connecting rod 407 is rotatably connected to the side wall of the first nut 406. The other end of the connecting rod 407 away from the first nut 406 is rotatably connected to the top of the rotating plate 402.

[0028] AsFigure 5 As shown in the figure, on the side of the top of the rotating plate 402 away from the fixed vertical rod 401, a third motor 409 is fixedly connected. The output end of the third motor 409 is fixedly connected with a second worm 410. The right side of the second worm 410 is meshed and connected with a second worm gear 411. The bottom of the second worm gear 411 is fixedly connected with a second connecting rod 412. The bottom of the second connecting rod 412 penetrates to the bottom of the rotating plate 402 and is fixedly connected with a watering tank 408. The outer wall of the second connecting rod 412 is rotationally connected with the rotating plate 402. On the side of the watering tank 408 away from the medicine storage tank 104, two symmetrically arranged spray nozzles 414 are provided. The left side wall of the watering tank 408 is fixedly connected with a water outlet pipe 110.

[0029] When it is necessary to adjust the angle of the spray nozzle 414 to improve the watering range of the device, start the second motor 404. The second motor 404 drives the first lead screw 405 connected to its output end to rotate. The rotation of the first lead screw 405 drives the first nut 406 threadedly connected to its outer wall to move up and down. The up and down movement of the first nut 406 drives the rotating plate 402 connected thereto to rotate with the connection point with the fixed vertical rod 401 as the fulcrum. The provided first connecting rod 407 makes the rotating plate 402 more stable during rotation.

[0030] While starting the second motor 404, start the third motor 409. The third motor 409 drives the second worm 410 connected to its output end to rotate. The rotation of the second worm 410 drives the second worm gear 411 meshed therewith to rotate. The rotation of the second worm gear 411 drives the second connecting rod 412 fixedly connected to its bottom to rotate. The rotation of the second connecting rod 412 drives the watering tank 408 fixedly connected to its bottom to rotate. The rotation of the watering tank 408 drives the spray nozzle 414 provided on its side wall to rotate, realizing the adjustment of the angle of the spray nozzle 414, thereby improving the spraying range of the device and improving the adaptability of the device.

[0031] It should be noted that both the third motor 409 and the second motor 404 are stepper motors that can rotate forward and backward, and the rotation angle of the watering tank 408 is 180°.

[0032] Next, the working principle of this agricultural spraying mechanical device will be specifically described.

[0033] As Figures 1-5 shown, when in use, first add the liquid medicine into the medicine storage tank 104 through the provided medicine injection port 105, and then start the servo motor 201. The servo motor 201 drives the rotating shaft 202 connected to its output end to rotate. The rotation of the rotating shaft 202 drives the stirring rod 203 fixedly connected to its side wall to rotate. The rotation of the stirring rod 203 enables the liquid medicine inside the medicine storage tank 104 to be stirred, realizing the full mixing of the liquid medicine and water.

[0034] When it is necessary to adjust the height of the device, start the first motor 306. The first motor 306 drives the worm 304 connected to its output end to rotate. The rotation of the worm 304 drives the worm wheel 303 meshed with it to rotate. The rotation of the worm wheel 303 drives the threaded nut 302 fixedly connected to its inner wall to rotate. The rotation of the threaded nut 302 drives the screw rod 307 threadedly connected to it to move up and down along the inner wall direction of the hollow cylindrical rod 301. The movement of the screw rod 307 drives the fixed horizontal plate 308 fixedly connected to its top to move. The arranged opening 311 and the limit block 310 prevent the screw rod 307 from rotating during the lifting and lowering process. The up and down movement of the fixed horizontal plate 308 drives the angle adjustment assembly 4 fixedly connected to it to move, realizing the height adjustment of the spray head 414, so as to adapt to crops of different heights. At the same time, the best spraying height is adjusted according to the growth situation of the crops, so that the pesticide can evenly cover the crops, improving the spraying effect.

[0035] When it is necessary to adjust the angle of the spray head 414 to increase the irrigation range of the device, start the second motor 404. The second motor 404 drives the first lead screw 405 connected to its output end to rotate. The rotation of the first lead screw 405 drives the first nut 406 threadedly connected to its outer wall to move up and down. The up and down movement of the first nut 406 drives the rotating plate 402 connected to it to rotate with the connection point with the fixed vertical rod 401 as the fulcrum. The arranged first connecting rod 407 makes the rotating plate 402 more stable during rotation.

[0036] When starting the second motor 404, start the third motor 409 at the same time. The third motor 409 drives the second worm 410 connected to its output end to rotate. The rotation of the second worm 410 drives the second worm wheel 411 meshed with it to rotate. The rotation of the second worm wheel 411 drives the second connecting rod 412 fixedly connected to its bottom to rotate. The rotation of the second connecting rod 412 drives the irrigation tank 408 fixedly connected to its bottom to rotate. The rotation of the irrigation tank 408 drives the spray head 414 arranged on its side wall to rotate, realizing the angle adjustment of the spray head 414, thereby increasing the spraying range of the device and improving the adaptability of the device.
