[0032] When the U-shaped rod 26 moves to the highest point of the spiral cam 2602, when the spiral cam 2602 continues to rotate, the rubber guide wheel 2601 will suddenly move downward, driving the U-shaped rod 26 to move downward, and the U-shaped rod 26 drives the piston plate 32 to move downward, so that the piston plate 32 compresses the air inside the compression cylinder 33, and the compressed air enters the liquid storage tank 29 through the air pipe 34, increasing the pressure inside the liquid storage tank 29. At this time, the liquid medicine passes through the spring hose 601, the through hole and the Y-shaped connecting pipe 12 and enters the two The inside of the arc-shaped water spray pipe 10 is then sprayed out from the atomizing nozzle 11. The sprayed liquid medicine mist will be in a certain range, and will adhere to the outer surface of the grape plant as the liquid medicine is sprayed. Through this device, the atomizing nozzle 11 can spray the liquid medicine after moving a certain distance.

[0033] In this embodiment, a crankshaft 22 is rotatably installed between the inner walls on opposite sides of the box body 1, and a curved neck 23 is provided on the outer surface of the crankshaft 22, and the curved neck 23 is eccentrically arranged with the crankshaft 22. A spring telescopic rod 24 is rotatably installed on the circumferential outer surface of the curved neck 23, and the telescopic end of the spring telescopic rod 24 is rotatably installed with the upper surface of the rotating rod 14. One end of the crankshaft 22 passes through the outer surface of the box body 1 and a hand wheel 16 is fixedly installed thereon. A latch 17 is slidably inserted into the outer surface of the hand wheel 16, and a pull block is fixedly installed on the end of the latch 17 away from the box body 1. A tension spring 19 is sleeved on the outer surface of the latch 17, and one end of the tension spring 19 is fixedly connected to the outer surface of the hand wheel 16, and the other end of the tension spring 19 is fixedly connected to the outer surface of the pull block. A plurality of positioning holes 18 are opened in the circular direction of the outer surface of the box body 1 close to the hand wheel 16, and the plurality of positioning holes 18 are matched with the latch 17.

[0034] Then the operator manually pushes the handrail 3 to move the box body 1 to the middle position of two adjacent ridges of grape plants through the universal wheel 4 and the front wheel 2. Then, the operator manually pulls the pin 17 out for a distance, and then turns the handwheel 16 to drive the crankshaft 22 to rotate. The crankshaft 22 drives the spring telescopic rod 24 to move downward through the curved neck 23. The spring telescopic rod 24 drives the rotating rod 14 to move downward through the telescopic end. The rotating rod 14 drives the guide wheel 15 to be exposed from the opening 13 and against the ground. At this time, the handwheel 16 is continued to be turned for a distance to make the spring telescopic rod 24 squeeze the rotating rod 14. The operator releases the pin 17. Under the action of the tension spring 19, the pin 17 will be inserted into the inside of the positioning hole 18. At this time, the position of the handwheel 16 is restricted. The device can be used to adjust the contact between the guide wheel 15 and the ground, which is convenient for the operator to use the device to spray medicine.

[0035] In this embodiment, a float rod is inserted through the bottom wall of the liquid storage tank 29, a float plate 30 is fixedly installed on the top of the float rod, a limit rod 31 is fixedly installed on the bottom end of the float rod through the lower surface of the liquid storage tank 29, a block is fixedly installed on the lower surface of the limit rod 31 near the end of the driven gear 35, and the block is arranged above the driven gear 35, a guide rod is fixedly installed on the bottom wall of the box body 1, the guide rod passes through the outer surface of the limit rod 31 and is slidably installed therewith, an indicator rod 21 is fixedly installed on the upper surface of the float plate 30, and the indicator rod 21 passes through the liquid storage tank 29 and the upper surface of the box body 1.

[0036] When the liquid in the liquid storage tank 29 decreases, the float plate 30 moves downward, and the float plate 30 drives the indicator rod 21 to move downward and retract into the liquid storage tank 29, so that the operator can intuitively see whether the liquid in the liquid storage tank 29 is sufficient. At the same time, the downward movement of the float plate 30 drives the limit rod 31 to move downward, and the limit rod 31 drives the card block to move downward until it contacts the teeth on the outer surface of the driven gear 35. At this time, the card block is moved by the rotation of the driven gear 35, and the reciprocating movement of the card block drives one end of the limit rod 31 to vibrate elastically, thereby making a sound to remind the operator that the remaining amount of liquid is insufficient, thereby avoiding negligence of the operator, which causes missed positions when spraying.

[0037] In this embodiment, a limiting groove 7 is formed on the outer surface of one side of the square fixed cylinder 5, and a limiting protrusion 8 is fixedly installed on the outer surface of the square slide rod 6. The limiting protrusion 8 is slidably installed with the inner wall of the limiting groove 7. A locking knob 9 is threadedly connected to the outer surface of the square fixed cylinder 5 near the top, and one end of the locking knob 9 passes through the inner wall of the square fixed cylinder 5 and abuts against the outer surface of the square slide rod 6. The cooperation between the limiting protrusion 8 and the limiting groove 7 prevents the square slide rod 6 from slipping out of the inside of the square fixed cylinder 5.

[0038] By loosening the locking knob 9, the square slide bar 6 can slide up and down inside the square fixed tube 5. After the operator adjusts the height of the arc-shaped water spray pipe 10, the arc-shaped water spray pipe 10 is restricted by tightening the locking knob 9. Through this device, the position of the arc-shaped water spray pipe 10 can be adjusted according to the height of the grape plants.

[0039] In this embodiment, two front wheels 2 are symmetrically rotatably installed on the lower surface of the box body 1 away from the liquid storage tank 29, two universal wheels 4 are symmetrically fixedly installed on the lower surface of the box body 1 relative to the front wheels 2, and a handrail 3 is fixedly installed on the end surface of the box body 1 close to the liquid storage tank 29. The operator manually pushes the handrail 3 to move the box body 1 to the middle position between two adjacent ridges of grape plants through the universal wheels 4 and the front wheels 2.

[0040] In this embodiment, when using the device, it is necessary to push the box 1 a short distance in advance so that the medicine liquid can enter the spring hose 601 and the arc-shaped water spray pipe 10 in advance to avoid omissions during spraying.

[0041] It should be noted that when the present invention is used, the operator adds the prepared liquid medicine into the liquid storage tank 29 through the liquid adding pipe 20, and the amount of liquid medicine added should be lower than the height of the air outlet end of the air pipe 34. After adding the liquid medicine, the liquid adding pipe 20 is sealed by the sealing cap;

[0042] Then the operator manually pushes the handrail 3 to move the box body 1 to the middle position of the two adjacent ridges of grape plants through the universal wheel 4 and the front wheel 2. Then, the operator manually pulls out the latch 17 by one end, and then turns the hand wheel 16 to drive the crankshaft 22 to rotate. The crankshaft 22 drives the spring telescopic rod 24 to move downward through the curved neck 23. The spring telescopic rod 24 drives the rotating rod 14 to move downward through the telescopic end. The rotating rod 14 drives the guide wheel 15 to be exposed from the opening 13 and against the ground. At this time, the hand wheel 16 is continued to be turned by one end to make the spring telescopic rod 24 squeeze the rotating rod 14. The operator releases the latch 17. Under the action of the tension spring 19, the latch 17 will be inserted into the inside of the positioning hole 18. At this time, the position of the hand wheel 16 is limited. The contact between the guide wheel 15 and the ground can be adjusted through this device, which is convenient for the operator to use the device to spray medicine.

[0043] The operator moves the device manually. Because the guide wheel 15 is against the ground, the movement of the device drives the guide wheel 15 to rotate. The guide wheel 15 drives one of the pulleys 37 to rotate. The pulley 37 drives another pulley 37 to rotate through the belt 38. The other pulley 37 drives the driving gear 36 to rotate. The driving gear 36 drives the driven gear 35 to rotate. The driven gear 35 drives the spiral cam 2602 to rotate. When the spiral cam 2602 rotates, the gradual protrusion of its outer surface causes it to drive the U-shaped rod 26 to move upward through the rubber guide wheel 2601. The U-shaped rod 26 drives the piston plate 32 to move upward. At this time, air enters the interior of the compression cylinder 33 through the one-way air intake valve. When the U-shaped rod 26 moves to the highest point of the spiral cam 2602, when the spiral cam 2602 continues to rotate, the rubber guide wheel 2601 will suddenly move downward, driving the U-shaped rod 26 to rotate. The rod 26 moves downward, and the U-shaped rod 26 drives the piston plate 32 to move downward, so that the piston plate 32 compresses the air inside the compression cylinder 33, and the compressed air enters the liquid storage tank 29 through the air pipe 34, and the pressure inside the liquid storage tank 29 is increased. At this time, the liquid medicine passes through the spring hose 601, the through hole and the Y-shaped connecting pipe 12 and enters the inside of the two arc-shaped water spraying pipes 10 respectively, and then is sprayed out from the atomizing nozzle 11. The sprayed liquid medicine mist will be in a certain range, and will adhere to the outer surface of the grape plant as the liquid medicine is sprayed. Through this device, the atomizing nozzle 11 can spray the liquid medicine after moving a distance, and with the spraying range of the atomizing nozzle 11, the liquid medicine can be evenly sprayed onto the outer surface of the grape plant. When the operator pushes the device slowly, the atomizing nozzle 11 will not spray too much liquid medicine at a certain position, thereby avoiding the waste of liquid medicine.

[0044] When the liquid in the liquid storage tank 29 decreases, the float plate 30 moves downward, and the float plate 30 drives the indicator rod 21 to move downward and retract into the liquid storage tank 29, so that the operator can intuitively see whether the liquid in the liquid storage tank 29 is sufficient. At the same time, the downward movement of the float plate 30 drives the limit rod 31 to move downward, and the limit rod 31 drives the card block to move downward until it contacts the teeth on the outer surface of the driven gear 35. At this time, the card block is moved by the rotation of the driven gear 35, and the reciprocating movement of the card block drives one end of the limit rod 31 to vibrate elastically, thereby making a sound to remind the operator that the remaining amount of liquid is insufficient, thereby avoiding negligence of the operator, which causes missed positions when spraying.

[0045] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
