[0029] A liquid pump 8 is fixed to the inner bottom of the liquid storage tank 1, a liquid pumping pipe 9 is fixed to the top of the liquid pump 8, both sides of the liquid pumping pipe 9 are connected to the spraying pipe 702 through a connecting hose 11, and a battery pack 12 is fixed to the top of the liquid storage tank 1.

[0030] In this embodiment, Figure 3 As shown, the first motor 3 is symmetrically fixed on both sides of the top of the liquid storage tank 1, and the top of the first motor 3 is connected to the slide rail 4. The slide rail 4 can rotate under the action of the first motor 3 to facilitate unfolding or storage.

[0031] In this embodiment, Figure 1 and Figure 3 As shown, a second motor 5 is fixed to the top of the slide rail 4, and the bottom of the second motor 5 is connected to the screw rod 6, the screw rod 6 is rotatably connected to the slide rail 4, the movable frame 701 is threadedly connected to the outside of the screw rod 6, and the movable frame 701 is slidably connected in the slide rail 4, the screw rod 6 can rotate under the action of the second motor 5, and at this time the movable frame 701 can slide up and down under the limiting action of the slide rail 4 and the screw rod 6, thereby driving the spray pipe 702 to move up and down, so as to facilitate the adjustment of the height of the spray pipe 702 according to the height of the crops.

[0032] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, a sleeve 703 is fixed to the inner end of the spray pipe 702, and a third motor 704 is fixed to the top of the sleeve 703. The output end of the third motor 704 is connected to the incomplete gear 705, and an arc-shaped extrusion plate 706 is fixed to the inner end face of the incomplete gear 705. The incomplete gear 705 can rotate under the action of the third motor 704, thereby driving the arc-shaped extrusion plate 706 to rotate.

[0033] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, a bracket 707 is fixed to the inner bottom of the movable frame 701, and a movable frame 708 passes through the bracket 707. A roller 709 is fixed to the outer end of the movable frame 708, and the roller 709 is in contact with the arc-shaped extrusion plate 706. During the rotation of the arc-shaped extrusion plate 706, the movable frame 708 is squeezed to move, and the roller 709 rolls on the arc-shaped extrusion plate 706, so as to reduce the friction between the movable frame 708 and the arc-shaped extrusion plate 706.

[0034] In this embodiment, Figure 3 and Figure 4 As shown, the inner side of the sleeve 703 is rotatably connected to the oil cylinder 711, and the first piston 710 is slidably connected inside the oil cylinder 711.

When the movable frame 708 is squeezed and moved, the first piston 710 moves accordingly, which facilitates the extraction of oil into the oil cylinder 711. When the movable frame 708 is not squeezed, the first piston 710 can automatically pop open under the action of the compression spring 712, which facilitates the pressing out of the hydraulic oil in the oil cylinder 711.

[0035] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, a gear ring 713 is fixed to the outside of the oil cylinder 711, and an oil pipe 714 is fixed to the outer end of the oil cylinder 711. When the incomplete gear 705 rotates and meshes with the gear ring 713, the oil cylinder 711 will rotate with the rotation of the incomplete gear 705, thereby driving the oil pipe 714 to rotate.

[0036] In this embodiment, Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, five groups of oil cylinders 716 are arranged on each oil pipe 714, and each group of oil cylinders 716 is provided with four oil cylinders, and the four oil cylinders 716 are evenly distributed on the oil pipe 714 in the circumferential direction. The spray plate 718 in the oil cylinder 716 at the bottom of the oil pipe 714 extends into the through hole 719. The spray holes on the four spray plates 718 in a group are of different sizes. The rotation of the oil pipe 714 will drive all the spray plates 718 thereon to rotate as a whole, so that different types of spray plates 718 can be switched to facilitate the flexible adjustment of the spray flow rate.

[0037] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the liquid extraction pipeline 9 is a "T"-shaped structure, and valves 10 are symmetrically arranged on both sides of the top of the liquid extraction pipeline 9. The two valves 10 can be opened simultaneously or individually, so that it is convenient to choose to use two spraying pipelines 702 or one of the spraying pipelines 702 according to needs.

[0038] The use method and advantages of the present invention: The crop cultivation fertilizer spraying device has the following working process:

[0039] like Figures 1 to 7As shown: the battery pack 12 is electrically connected to the driving wheel 2, the first motor 3, the second motor 5, the third motor 704 and the liquid pump 8. The battery pack 12 converts DC power into AC power for the entire device under the action of the inverter. The driving wheel 2 can drive the device to move. The rotation of the screw rod 6 will drive the moving frame 701 and the spraying pipe 702 to move up and down. The height of the spraying pipe 702 can be adjusted according to the height of the crops. The front side of the liquid storage tank 1 is provided with a liquid inlet valve to introduce liquid fertilizer into the liquid storage tank 1. The two slide rails 4 can rotate independently. They can be rotated and unfolded to use two spray pipes 702 or one of the spray pipes 702 according to needs. After using the spray pipe 702, it is rotated to the longitudinal state for storage. When using the two spray pipes 702 at the same time, it is necessary to open the two valves 10 at the same time. When using one of the spray pipes 702, only the corresponding valve 10 needs to be opened. When the incomplete gear 705 rotates, the arc-shaped extrusion plate 706 first squeezes the movable frame 708 to move, and the first piston 710 moves accordingly and pumps oil into the oil cylinder 711 The spray plate 718 in the through hole 719 moves with the corresponding second piston 717 and leaves the through hole 719. When the arc-shaped extrusion plate 706 squeezes the movable frame 708 to the maximum extent, the incomplete gear 705 is meshed and connected with the ring gear 713. Then, the incomplete gear 705 rotates to drive the oil cylinder 711 to rotate, thereby driving the oil pipe 714 to rotate. The oil pipe 714 rotates 90 degrees each time to facilitate the switching of the next spray plate 718. When the arc-shaped extrusion plate 706 does not squeeze the movable frame 708, the first piston 710 automatically returns to the original position. The second piston 717 corresponding to the switched spray plate 718 moves under the action of oil pressure, and the switched spray plate 718 extends into the through hole 719. Each group of spray plates 718 is provided with four, and the spray holes on the four spray plates 718 are of different sizes. The corresponding type of spray plate 718 can be selected according to demand. The spray flow rate of different types of spray plates 718 is different. The liquid pump 8 draws the fertilizer into the liquid extraction pipe 9, and the fertilizer enters the spraying pipe 702 through the connecting hose 11. The spray plate 718 in the through hole 719 will spray the fertilizer.

[0040] In summary, the crop cultivation fertilizer spraying device achieves the purpose of flexible adjustment of spraying flow, adjustable spraying height, convenient storage and adjustable spraying range, and meets people's usage needs.
