DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] According to Figures 1-4As shown in the figure, it includes a connecting pipe 1. A water pump 11 is arranged at a position on one side of the side surface of the connecting pipe 1, and a shunt pipe 12 is installed at a position on the top of the side surface of the connecting pipe 1. A through hole 13 is opened on the inner wall of the top end of the shunt pipe 12, and sliders 14 are arranged on both sides of the inner wall of the through hole 13.

[0021] A lifting pipe 2 is slidably arranged inside the through hole 13. A telescopic hose 20 is installed at the bottom end of the lifting pipe 2. The bottom end of the lifting pipe 2 passes through the inner wall of the top end of the shunt pipe 12 through the through hole 13 and extends into the inside of the shunt pipe 12. The bottom end of the telescopic hose 20 is communicated with the inside of the connecting pipe 1. A plurality of groups of threaded holes 21 are opened on both sides of the side surface of the lifting pipe 2, and sliding grooves 22 are opened on the other two sides of the side surface of the lifting pipe 2. The plurality of groups of threaded holes 21 are uniformly and arrayed in a straight line on the side surface of the lifting pipe 2. The sliders 14 are all arranged inside the corresponding sliding grooves 22, and the sliders 14 are slidably connected with the sliding grooves 22. A shunt plate 23 is communicated with the top end of the lifting pipe 2, and a plurality of groups of spray heads 24 are communicated with the side surface of the shunt plate 23. The plurality of groups of spray heads 24 are centrosymmetrically arranged with the center point of the shunt plate 23 as the center. Installation blocks 3 are installed on both sides of the top end of the shunt pipe 12 near the lifting pipe 2.

[0022] Screws 31 are movably screwed inside the installation blocks 3. A hand-held rod 32 is installed at one end of each screw 31. A bolt 33 is installed at the other end of each screw 31. The outer diameter of the bolt 33 is adapted to the inner diameter of the threaded hole 21, and one end of the bolt 33 extends into the threaded hole 21 and is movably screwed with it.

[0023] During use, the operator can start the water pump 11. Thus, under the operation of the water pump 11, the pesticide water inside the connecting pipe 1 can be injected into the inside of the lifting pipe 2 through the telescopic hose 20 and can flow into the inside of the shunt plate 23. Finally, it can be sprayed out through the plurality of groups of spray heads 24, so as to perform a pesticide spraying operation on the crops.

[0024] When it is necessary to adjust the heights of the flow dividing plate 23 and the medicine spraying head 24, the user can rotate the corresponding screw rod 31 through the two groups of hand-held rods 32, so that the corresponding bolt 33 can rotate accordingly, so that the corresponding bolt 33 can rotate out of the interior of the corresponding threaded hole 21. After that, the user can move the flow dividing plate 23 and the medicine spraying head 24 upward, so that the lifting pipe 2 can move upward correspondingly inside the flow dividing pipe 12 and the through hole 13, so that the two groups of sliders 14 can slide correspondingly inside the corresponding sliding grooves 22 respectively, so that the lifting pipe 2 is more stable and not prone to shaking when moving upward. At the same time, the telescopic hose 20 will change its length upward correspondingly, so as to ensure that the interior of the connecting pipe 1 can always be connected to the interior of the lifting pipe 2 through the telescopic hose 20. Finally, the user can rotate the corresponding screw rod 31 through the two groups of hand-held rods 32, so that the corresponding bolt 33 can rotate accordingly, so that one end of the corresponding bolt 33 can be screwed and fixed to the interior of the corresponding threaded hole 21, so that the lifting pipe 2 can be fixed. At this time, the upward adjustment operation of the flow dividing plate 23 and the medicine spraying head 24 can be completed. Since several groups of threaded holes 21 are evenly and arrayed in a straight line on the side surface of the lifting pipe 2, the flow dividing plate 23 and the medicine spraying head 24 can realize multi-stage upward adjustment.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
