[0022] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 1-4 :
[0023] A fully automatic high-stalk crop sprayer includes a walking mechanism 1 driven by a power device, the walking mechanism 1 carries a frame 2, the frame 2 is provided with a medicine box 3 for containing liquid medicine and a medicine pump for conveying the liquid medicine, and the left and right sides of the frame 2 are respectively provided with a spraying mechanism, the spraying mechanism includes an adjustment seat 4, an adjustment rod 5 and a spray rod 6, the adjustment seat 4 is fixedly connected to the frame 2, one end of the adjustment rod 5 is rotatably connected to the adjustment seat 4, one side of the adjustment seat 4 is provided with an arc-shaped adjustment groove 7, the adjustment rod 5 is provided with an adjustment locking piece 8 that slides with the arc-shaped adjustment groove 7, the spray rod 6 is arranged parallel to the outside of the adjustment rod 5 and fixedly connected to it through a number of connection points, the spray rod 6 is connected to the medicine pump and is provided with a number of nozzles 9 for spraying outward at intervals.
[0024] Compare with Figure 1 During operation, the spraying mechanism is adjusted to the appropriate position, the power device is started, the walking mechanism 1 carries the various functional components and moves among the high-pole crop garden. At the same time, the medicine pump is started, and the liquid medicine in the medicine box 3 is transported into the spray rod 6 through the medicine pump, and then sprayed out by the nozzle 9 on the spray rod 6.
[0025] In this embodiment, the adjustment locking member 8 includes an adjusting bolt and a locking nut. The adjusting bolt passes through the adjusting rod 5 and slides in the arc-shaped adjustment groove 7. When the locking nut is tightened, the adjusting rod 5 and the adjustment seat 4 are locked. When adjusting, the locking nut is first loosened, and the angle of the adjusting rod 5 and the spray rod 6 is adjusted by sliding the adjusting bolt in the arc-shaped adjustment groove 7, thereby adjusting the spraying height and spraying range of the spray rod 6.
[0026] In this embodiment, the specific structure of the adjusting rod 5 and the spray rod 6 is: the adjusting rod 5 is flush with both ends of the spray rod 6, the adjusting rod 5 and the spray rod 6 are spaced apart and welded and fixed by a plurality of connecting rods 10, and the gap between the adjusting rod 5 and the spray rod 6 forms an accommodating gap for the adjusting locking member 8.
[0027] The nozzles 9 are detachably connected to the spray bars 6, and each nozzle 9 is provided with a corresponding control valve. By replacing the nozzles 9, different specifications of liquid spray can be obtained. By selectively closing the nozzles 9, the spraying amount can be increased or decreased. For example, in the early stage of crop growth, fewer nozzles 9 can be used, and in the late stage of crop growth, more nozzles 9 can be used.
[0028] An articulated shaft locking member 11 is provided on the articulated shaft between the adjustment seat 4 and the adjustment rod 5. The articulated shaft locking member 11 and the adjustment locking member 8 form a double locking structure.
