[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 5This utility model provides a technical solution: an agricultural plant protection spraying device, including a movable base 1, a lower cylinder 2 mounted on the top of the movable base 1, a liquid storage chamber 3 inside the lower cylinder 2, and a receiving groove 4 inside the lower cylinder 2 and outside the liquid storage chamber 3. An upper cylinder 5 is slidably connected inside the receiving groove 4, with a pull-out structure, allowing the upper cylinder 5 to be pulled out and unfolded from the receiving groove 4, which helps to expand the overall space of the lower cylinder 2 and the upper cylinder 5, storing more liquid. A positioning hole 13 is provided on one side of the upper cylinder 5, and a threaded post 14 is threadedly connected to one side of the lower cylinder 2. One end of the threaded post 14 passes through the receiving groove 4 and is inserted into the positioning hole 13. As the threaded post 14 rotates, one end of it moves accordingly and inserts into the positioning hole 13. The upper cylinder 5 is easily fixed in position by being pulled out. A support plate 6 is rotatably connected inside the upper cylinder 5. Two first stirring shafts 7 are rotatably connected to the bottom of the support plate 6. A second stirring shaft 8 is slidably connected inside each of the two first stirring shafts 7. Multiple stirring blades 9 are installed on the outer sides of both the two first stirring shafts 7 and the two second stirring shafts 8. A motor 10 is fixedly installed at the top of the upper cylinder 5. The output end of the motor 10 is connected to the support plate 6, driving the support plate 6 to rotate, which in turn drives the two first stirring shafts 7 and the second stirring shafts 8 at its bottom to rotate, facilitating the mixing of water and medicine. Both the first stirring shafts 7 and the second stirring shaft 8 have a cuboid structure, ensuring that their rotation remains consistent while they slide. First gears 11 are installed on the outer side of the first stirring shaft 7 and on top of multiple stirring blades 9. An internal gear ring 12 is installed inside the upper cylinder 5 and on one side of the first gears 11. The internal gear ring 12 meshes with two of the first gears 11, causing the first gears 11 to rotate with the first stirring shaft 7 as they revolve around it. During meshing with the internal gear ring 12, the first stirring shaft 7 and the second stirring shaft 8 rotate, which helps to increase the stirring force of water and medicine, making the mixture more uniform. A feed inlet 21 is opened on the top of the upper cylinder 5 and on one side of the motor 10. A sealing plug 22 is threaded inside the feed inlet 21. Rotation of the sealing plug 22 facilitates sealing or opening the feed inlet 21. An adjuster 1 is installed on the top of the movable base 1 and on one side of the lower cylinder 2. 5. A support frame 16 is rotatably connected to one side of the regulator 15. A spraying frame 17 is connected to the top of the support frame 16. Multiple nozzles 18 are installed on one side of the spraying frame 17. A water pump 19 is installed on the outer wall of the lower cylinder 2. The input end of the water pump 19 is connected to the liquid storage chamber 3, and the output end of the water pump 19 is connected to a guide pipe 20. One end of the guide pipe 20 is connected to the spraying frame 17. Under the action of the water pump 19, the liquid in the liquid storage chamber 3 is guided by the guide pipe 20 to the spraying frame 17 and sprayed onto the crops by the multiple nozzles 18. A worm gear 26 and a worm 27 are rotatably connected inside the regulator 15. The worm gear 26 and the worm 27 mesh with each other. A handle 28 is rotatably connected to the outer wall of the regulator 15. The worm gear 26 and the worm 27 are respectively connected to the support frame 16 and the handle 28.Under the action of the worm gear 26 and worm 27, the throttle 28 is driven to rotate with the support frame 16, facilitating the rotation of the support frame 16 and adjusting the angle of the sprayer frame 17. A water level sensor 23 is installed inside the liquid storage chamber 3, located on one side of the multiple stirring blades 9. A controller 24 is installed on the top of the movable base 1, on the side of the motor 10 furthest from the feed inlet 21. A warning light 25 is installed on one side of the controller 24, working in conjunction with the water level sensor 23 to promptly alert the user when the water level is low.

[0024] In summary, when using this agricultural plant protection spraying device, the upper cylinder 5 is pulled out from the receiving groove 4 inside the lower cylinder 2, and the threaded post 14 connected to the lower cylinder 2 is rotated so that one end of it is displaced and inserted into the positioning hole 13 on the side of the upper cylinder 5, thus fixing the upper cylinder 5 in place. Simultaneously, because the first stirring shaft 7 and the second stirring shaft 8 are slidably connected inside the upper cylinder 5, as the distance between the upper cylinder 5 and the lower cylinder 2 increases, the second stirring shaft 8 slides out a corresponding length from the first stirring shaft 7 under the action of gravity. At this time, water and pesticide are introduced into the upper cylinder 5 and the lower cylinder 2 through the feed inlet 21. The motor 10 drives the support plate 6 to rotate, causing the two bottom first stirring shafts 7 and the second stirring shaft 8 to revolve. The stirring blades 9 on the outer sides of the first stirring shafts 7 and the second stirring shaft 8 stir the water and pesticide. With the first gear 11 on the outer side of the two first stirring shafts 7 meshing with the inner gear ring 12 inside the upper cylinder 5, and the upper cylinder 5 rotatingly connected to the two first stirring shafts 7, the first gear 11, in conjunction with the cuboid structure of the first stirring shafts 7 and the second stirring shaft 8, triggers the first stirring shafts 7 and the second stirring shaft 8 to rotate as the first stirring shafts 7 revolve around each other. The water pump 19 guides the liquid in the storage chamber 3 inside the lower cylinder 2 through the guide pipe 20 to the spray frame 17, and then sprays it outwards through multiple nozzles 18. If necessary, the throttle 28 can be rotated to drive the worm 27 inside the regulator 15 to rotate. With the worm wheel 26 and the worm 27 meshing, and the worm wheel 26 and the worm 27 being connected to the support frame 16 and the throttle 28 respectively, the support frame 16 is driven to rotate, adjusting the angle between the support frame 16 and the spray frame 17 at one end.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
