DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Example: Reference Figure 1-7 The plant protection drone with a medicine box for anti-vibration shown in the figure comprises a drone body 1, on which four shock absorbers 2 are arranged, and a medicine storage box 3 is arranged at the bottom of the four shock absorbers 2. With the help of the four shock absorbers 2, a longitudinal shock absorbing effect can be provided for the medicine storage box 3 to reduce the vibration amplitude of the medicine storage box 3. The bottom of the medicine storage box 3 is fixedly connected with a medicine inlet pipe 4, and a first valve is arranged on the medicine inlet pipe 4. Two columns 5 are fixed between the upper and lower inner walls of the medicine storage box 3. The outer sliding sleeves of the two columns 5 are connected with a floating plate 6. The floating plate 6 and the inner wall gap of the medicine storage box 3 are matched. Two fixed blocks 7 are fixed on the floating plate 6. The fixed block 7 is provided with a receiving groove 8. A spring 9 is fixed inside the receiving groove 8. A clamping block 10 is fixed to the other end of the spring 9. The cross section of the clamping block 10 is a right-angle trapezoidal structure, and the clamping block 1 0 is slidably matched with the inner wall of the storage groove 8, a reserved groove 11 is provided on the column 5, and a plurality of tooth columns 12 arranged linearly in the longitudinal direction are fixed inside the reserved groove 11, and the cross section of the tooth column 12 is a right-angled triangle structure, and the clamping block 10 is clamped between two adjacent tooth columns 12, and a traction rope 13 is fixed on the clamping block 10, and the spring 9 is sleeved on the outside of the traction rope 13. A through hole 14 is provided on the top of the medicine storage box 3, and a handle 15 is fixed after the other end of the traction rope 13 passes through the through hole 14. A sliding groove for the traction rope 13 to pass through is provided on the fixed block 7, and a spraying component is provided at the bottom of the medicine storage box 3, and the spraying component is used to spray medicine, and a limited position protection component is provided between the drone body 1 and the medicine storage box 3, and the limited position protection component is used to improve the stability of the connection between the drone body 1 and the medicine storage box 3;

[0026] With the help of the medicine inside the medicine storage box 3, the floating plate 6 is buckled on the top of the medicine. As the medicine in the medicine storage box 3 is continuously discharged by the spraying assembly, the floating plate 6 will move down as the liquid level inside the medicine storage box 3 drops. The block 10 pushed by the elastic force of the spring 9 cooperates with the multiple tooth columns 12 on the column 5, so that the floating plate 6 can only move downward. In this way, the medicine in the medicine storage box 3 is not easy to fluctuate and shake when taking off and landing with the drone body 1, which is beneficial to the flight stability of the medicine storage box 3, the medicine and the drone body 1. Pull the handle 15 to drive the traction rope 13 to pull the block 10 to move inside the storage groove 8. In this way, the block 10 is separated from the reserved groove 11 and is no longer restricted by the tooth column 12. At this time, the floating plate 6 can move up and down along the two columns 5, which is convenient for replenishing medicine in the medicine storage box 3 along the medicine inlet pipe 4.

[0027] Among them, one side of the medicine storage box 3 is fixedly connected with an overflow pipe 16, and a second valve is arranged on the overflow pipe 16. The setting of the overflow pipe 16 can control the storage amount of medicine inside the medicine storage box 3, so that the storage of medicine in the medicine storage box 3 can be controlled within an appropriate range.

[0028] Among them, a counterweight block 17 is embedded at the bottom of the floating plate 6. The use of the counterweight block 17 makes the floating plate 6 move down more smoothly as the liquid level of the medicine drops, so that the floating plate 6 can be close to the medicine and reduce the shaking amplitude of the medicine during flight.

[0029] The spray assembly includes two carrier blocks 18, both carrier blocks 18 are fixedly mounted at the bottom of the medicine storage box 3, and a pump 19 is arranged between the two carrier blocks 18, a guide pipe 20 is fixedly connected between the liquid inlet of the pump 19 and the medicine storage box 3, a delivery pipe 21 is fixedly connected to the liquid outlet of the pump 19, a spray pipe 22 is fixedly connected to the bottom end of the delivery pipe 21, sealing blocks 23 are fixed at both ends of the spray pipe 22, and a plurality of nozzles are arranged on the spray pipe 22;

[0030] The medicine in the medicine storage box 3 is led out by means of the pump 19 so as to be sprayed out along the multiple nozzles on the spray pipe 22 to carry out the spraying operation of the medicine.

[0031] The limit protection assembly includes a fixed plate 24 and a telescopic rod 26. The fixed plate 24 is fixedly mounted on the top of the medicine storage box 3. The telescopic rod 26 is arranged on the drone body 1. A sleeve 25 is fixed on the top of the fixed plate 24. The sleeve 25 is sleeved on the outside of the telescopic rod 26. Two limit rods 27 are fixed on the outer wall of the telescopic rod 26. A limit groove for the limit rod 27 to slide is opened on the sleeve 25.

[0032] With the help of the sleeve 25 and the telescopic rod 26, the medicine storage box 3 can only shake in the longitudinal direction compared to the drone body 1. The coordinated use of the limit rod 27 and the limit groove can prevent the sleeve 25 and the telescopic rod 26 from being completely separated, thereby ensuring the safe use of the shock absorber 2.

[0033] Working principle of this utility model:

[0034] When in use, the medicine storage box 3 is driven to take off by the drone body 1, and the medicine inside the medicine storage box 3 is led out by the pump 19, so that the medicine enters the spray pipe 22 and is sprayed out along the nozzle on the spray pipe 22 to perform the medicine spraying operation. As the liquid level in the medicine storage box 3 drops, the float plate 6 moves down with the drop of the liquid level under the traction of the counterweight block 17. The float plate 6 floats above the medicine with its own buoyancy. When the float plate 6 moves down, it will drive the block 10 to move down. The block 10 pushed by the elastic force of the spring 9 cooperates with the multiple tooth columns 12 on the column 5, so that the float plate 6 can only move down but not up. In this way, when the medicine storage box 3 takes off and lands and moves with the drone body 1, the float plate 6 can reduce the fluctuation amplitude of the medicine in the medicine storage box 3, making the medicine more stable. The coordinated use of the four shock absorbers 2 further improves the shock absorption effect of the medicine storage box 3 when flying with the drone body 1.

[0035] When the medicine in the medicine storage box 3 is used up, the drone body 1 can be controlled to drive the medicine storage box 3 to land on the ground, and the traction rope 13 can be pulled by the handle 15, so that the traction rope 13 pulls the card block 10 into the interior of the storage groove 8. In this way, the card block 10 is away from the reserved groove 11 and no longer contacts the tooth column 12. At this time, the float plate 6 can slide up and down along the column 5 and replenish the medicine into the medicine storage box 3 along the medicine inlet pipe 4, so that the medicine pushes the float plate 6 to move up until the medicine overflows along the overflow pipe 16, and the first valve on the medicine inlet pipe 4 is closed. When the overflow pipe 16 no longer overflows medicine, the second valve on the overflow pipe 16 is closed, and the replenishment of the medicine in the medicine storage box 3 is completed.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
