[0002] As a major agricultural country, China needs to carry out a large number of agricultural plant protection operations every year. In order to complete a large number of operations in a short period of time and improve the overall efficiency, operators will use plant protection drones to spray pesticides. Plant protection drones are composed of multiple parts such as the fuselage, nozzles and medicine dispensing boxes. Among them, the medicine dispensing box is one of the indispensable parts of plant protection drones during use.

[0003] At present, before the existing plant protection drones start spraying, the staff directly pours the medicine and water into the medicine preparation box for preparation. After the preparation is completed, the drone can be remotely controlled for spraying. During the flight of the plant protection drone, due to the relatively simple overall structure of the medicine preparation box, it is difficult for the staff to judge the remaining amount of medicine in the medicine box, which can easily cause the drone to return to the airport to add medicine when there is medicine in the medicine box, or to continue plant protection work without medicine, which will affect the spraying efficiency of the drone. To this end, we propose a medicine preparation box for plant protection drones to solve the above problems. Utility Model Content

The medicine dispensing box body 1 is covered with a box cover 2, and a threaded cover 5 is provided inside the box cover 2. The bottom end of the medicine dispensing box body 1 is connected to a water outlet pipe 6, and a floating plate 7 is inserted inside the medicine dispensing box body 1. A connecting rod 9 is vertically connected to the upper side of the floating plate 7. The top end of the connecting rod 9 extends to the outside of the box cover 2 and is distributed with a moving block 10. The bottom end of the moving block 10 is connected to a contact sensor 11. The contact sensor 11 is provided with two groups, and the other group of contact sensors 11 is connected to the box cover 2. At the top position, there is a certain distance between the box cover 2 and the drone body 3, so that the moving block 10 can move up and down smoothly. The contact sensor 11 is an existing mature technology, mainly including a contact head, a sensor chip, a signal processing circuit and other parts. When the upper and lower groups of contact sensors 11 contact each other, the elastic resistance inside the sensor chip will change, resulting in a voltage signal of the resistance change being transmitted to the signal processing circuit for processing, and finally a digital signal is output to the control handle of the drone body 3, which is used to determine whether the medicine inside the dispensing box 1 is used up.

[0024] Further, see Figure 1 and Figure 2 It can be known that a fixing bar 13 is connected to the bottom end of the drone body 3, and two groups of mounting plates 4 are connected to the upper side of the fixing bar 13 by bolts, and the medicine dispensing box 1 is distributed on the side where the two groups of mounting plates 4 are close to each other. Through the cooperation between the fixing bar 13 and the mounting plate 4, it is convenient for the staff to quickly remove the medicine dispensing box 1 from the inner side of the two groups of mounting plates 4 for inspection and maintenance.

[0025] Further, see Figure 3It can be known that guide rods 8 are vertically connected to the corners of the bottom end of the box cover 2, and a movable groove is opened inside the floating plate 7 at a position corresponding to the guide rod 8. The bottom end of the guide rod 8 is in contact with the inner wall of the dispensing box 1. The floating plate 7 can be guided by four groups of guide rods 8 and the movable groove opened inside the floating plate 7 to ensure the vertical movement of the moving block 10. In addition, when the medicine liquid inside the dispensing box 1 oscillates or tilts, the floating plate 7 will not shake significantly due to the restriction of the guide rod 8, thereby preventing the medicine liquid under the floating plate 7 from tilting and oscillating significantly.

[0026] Further, see Figure 5 It can be known that a through groove is opened inside the box cover 2, and a sealing ring 15 is glued to the inner wall of the through groove. The inner wall of the sealing ring 15 is tightly fitted with the outer wall of the connecting rod 9. The opening of the through groove can meet the up and down movement requirements of the connecting rod 9, and the sealing ring 15 glued to the inner wall of the through groove can ensure the sealing of the inside of the box cover 2.

[0027] Further, see Figure 2 and Figure 3 It can be known that the dispensing box body 1 and the box cover 2 are symmetrically connected with a docking plate 12 on one side close to each other, and the upper and lower sets of docking plates 12 are connected by bolts. Through the docking plate 12 connected between the dispensing box body 1 and the box cover 2, and in conjunction with the setting of the bolts, it is convenient for the staff to disassemble the dispensing box body 1 and the box cover 2, thereby facilitating the staff to clean the dispensing box body 1 and the box cover 2.

[0028] Further, see Figure 5 It can be known that a threaded rod 14 is connected to the top of the connecting rod 9, and a threaded groove matched with the threaded rod 14 is opened inside the moving block 10. Through the mutual cooperation of the threaded rod 14 and the threaded groove, it is convenient for the staff to remove the moving block 10 from the top of the connecting rod 9 to prevent the upper and lower sets of contact sensors 11 from always contacting and transmitting signals when not in use.

[0029] Further, see Figure 2 It can be known that the mounting plate 4 is arranged as an L-shaped structure, and a rubber pad is glued on one side of the mounting plate 4 close to each other. The mounting plate 4 arranged in an L-shaped structure can increase the limiting area of ​​the medicine dispensing box 1, and combined with the connection with the rubber pad, the stability of the medicine dispensing box 1 when installed on the inner side of two sets of mounting plates 4 can be increased.
