[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-4In this embodiment of the present invention, a mechanized spraying device for agricultural production includes an electric push cylinder 1. A sliding plate 2 is fixedly installed at the output end of the electric push cylinder 1. The cross-section of the sliding plate 2 is U-shaped. Outwardly protruding tooth blocks 3 are integrally formed on both sides of the sliding plate 2. Gears 6 are meshed on the outer sides of the two tooth blocks 3. A rotating frame 7 is fixedly installed on the top of the gears 6. A water pipe 8 is fixedly installed on the outer wall of the lower longitudinal rod of the rotating frame 7. A hose 9 is fixedly connected to the input end of the water pipe 8. A connecting pipe 10 is fixedly connected to the input end of the hose 9. A support mechanism is provided at the bottom end of the sliding plate 2. A limit sensing mechanism is installed at one end of the support mechanism.

[0015] In this embodiment: The device is installed on a tractor. When spraying crops, the pesticide pump draws out the pesticide solution and inputs it into the connecting pipe 10, then into the hose 9, and then into the water pipe 8. Finally, it is sprayed out from the nozzle at the bottom of the water pipe 8. When the width of the sprayed farmland changes, the electric push cylinder 1 is activated. The electric push cylinder 1 shortens and pulls the sliding plate 2 to move synchronously. The sliding plate 2 drives the gear 6 to rotate through the tooth block 3. The rotating gear 6 drives the rotating frame 7 on top to rotate synchronously, so that the two rotating frames 7 rotate in opposite directions and unfold. The angle of rotation of the rotating frame 7 is limited by adjusting the limit sensing mechanism to suit farmland of different widths.

[0016] Please refer to this carefully. Figure 1 , Figure 2 The support mechanism includes a fixed plate 4 located below the sliding plate 2. The top ends of the two longitudinal rods of the fixed plate 4 are provided with downwardly recessed sliding grooves 16. Sliding blocks 17 are slidably installed on the inner wall of the sliding grooves 16. The top end of the sliding blocks 17 is integrally formed with the bottom end of the sliding plate 2. An mounting plate 5 is welded to the outer side of the fixed plate 4. A rotating sleeve is integrally formed on the top end of the mounting plate 5. The inner wall of the rotating sleeve is rotatably connected to the shaft at the bottom end of the gear 6 through a bearing.

[0017] In this embodiment: when the sliding plate 2 slides, the sliding plate 2 drives the sliding block 17 to slide in the sliding groove 16 to ensure the horizontal sliding of the sliding plate 2; When gear 6 rotates, the shaft of gear 6 rotates inside the rotating sleeve, providing support for the rotation of gear 6.

[0018] Please refer to this carefully. Figure 3 and Figure 4 The limit sensing mechanism includes a guide frame 11 fixedly installed at one end of a fixed plate 4. A movable plate 13 extending above the guide frame 11 is slidably installed in the track of the guide frame 11. A pressure sensor 14 is installed inside the movable plate 13 above the guide frame 11. The pressure sensor 14 is electrically connected to the electric push cylinder 1 through a controller.

[0019] In this embodiment: before the rotating frame 7 is rotated open, the moving plate 13 is pulled to move along the inner wall of the guide frame 11. The moving plate 13 drives the pressure sensor 14 installed on it to move synchronously until the pressure sensor 14 moves to a suitable position. Then the adjusted moving plate 13 is fixed. During the sliding process of the sliding plate 2, it gradually approaches the pressure sensor 14 until it contacts the sensing end of the pressure sensor 14. At this time, the pressure signal is converted into an electrical signal and sent to the controller. The controller controls the electric push cylinder 1 to stop running, thereby achieving the purpose of limiting the opening angle of the rotating frame 7.

[0020] Please refer to this carefully. Figure 4 The guide frame 11 has long slots 12 on both sides. The movable plate 13 is located inside the guide frame 11 and has screw holes that are aligned with the slots 12. The inner wall of the screw holes is threaded with locking screws 15. The two ends of the locking screws 15 extend to the outside of the guide frame 11, and one end of the locking screws 15 is integrally formed with a handle. A rubber damper is fixedly installed on the side of the handle near the guide frame 11.

[0021] In this embodiment: after the movable plate 13 has slid, the handle is rotated, which drives the locking screw 15 to screw in until the rubber damper at one end of the handle is tightly pressed against the outside of the guide frame 11. At this time, the rubber damper is deformed under pressure, forming sufficient friction to prevent the movable plate 13 from changing position after adjustment.

[0022] 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.
