The auxiliary device 4 also includes an adjusting rod 44, which is installed inside the auxiliary device 4 and the adjusting rod 44 is set to be L-shaped. A rectangular groove is opened inside the vertical part of the adjusting rod 44.

The second gear 48 is arranged on the outside of the auxiliary device 4 and the second gear 48 at the rear end is meshed and connected with the first gear 41. Under normal circumstances, the spraying port of the second spray plate 47 faces the top. The two auxiliary devices 4 are respectively fixedly connected to the two support rods 11 on the left and right sides to ensure the normal operation of the device.

Working principle: The liquid medicine for treating the disease is injected into the storage bin 2 through an external feed pipe, and then the control center 10 is used to control the two linear drive components 33 to retract the two push rods 330. The two push rods 330 are retracted and moved to drive the fixed plate 320 and the spraying piece 32 to move. The spray holes between the spraying piece 32 and the first spraying plate 31 are overlapped in the initial state. After the spraying piece 32 moves, the spray holes at the spraying piece 32 are staggered with the spray holes at the first spraying plate 31. The spray holes at the first spraying plate 31 are partially blocked by the unopened spray holes of the first spraying piece 32. At this time, the amount of liquid medicine sprayed from the spraying device 3 is reduced, and the control The control center 10 controls the rotation drive assembly 40 to start, and the rotation drive assembly 40 starts to drive the first gear 41 to rotate. The rotation of the first gear 41 drives the fixed rod 42 and the screw 420 to rotate. The rotation of the screw 420 drives the movable block 43 to move. In the initial state, the movable block 43 blocks the vertical rectangular groove of the L-shaped adjustment rod 44. At this time, the liquid medicine cannot enter the transmission plate 46 through the adjustment rod 44. After the screw 420 rotates, the movable block 43 gradually moves and no longer blocks the vertical part of the adjustment rod 44. At this time, the size of the gap between the movable block 43 and the adjustment rod 44 is the amount of medicine that the adjustment rod 44 can deliver in a single time. The movable block 43 blocks the inner diameter of the rectangular groove of the vertical part of the adjusting rod 44 by half. At this time, the sum of the amount of liquid medicine delivered by the two adjusting rods 44 at a time and the amount of liquid medicine sprayed at the first spraying plate 31 at a time after adjustment is equal to the amount of liquid medicine sprayed by the first spraying plate 31 at a time before adjustment. This avoids the situation where the amount of liquid medicine sprayed is not adjusted when adjusting the uniformity of liquid medicine spraying, so that the amount of liquid medicine is easy to exceed the amount of liquid medicine that crops in a single area can accept, thereby causing pesticide damage to crops. The first gear 41 rotates the second gear 48 at the rear end to rotate, and the second gear 48 at the rear end rotates to drive the transmission plate 46 and the second spraying plate 4 7 is rotated, and when the movable block 43 only blocks half of the rectangular groove, a certain angle is formed between the second spray plate 47 and the first spray plate 31, and then the pump 30 is turned on to extract the liquid medicine in the storage bin 2 and transport it to the delivery pipe 300 and the elastic tube 301, and then the delivery pipe 300 and the elastic tube 301 transport it to the first spray plate 31 and the second spray plate 47. At this time, the first spray plate 31 sprays the liquid medicine from the top of the crops, and the second spray plate 47 sprays the liquid medicine from both sides of the top of the crops, so that the liquid medicine for controlling diseases and pests is retained on the surface of the crops as much as possible, thereby improving the spraying effect of the device and facilitating the use of users;

When the drone 1 sprays liquid fertilizer, the liquid fertilizer is poured into the storage bin 2, and then the double-headed motor 21 is turned on. The double-headed motor 21 is turned on to drive the first output rod 210 and the second output rod 26 to rotate. The second output rod 26 rotates to drive the stirring shaft 27 to stir the liquid fertilizer to prevent the liquid from settling. The first output rod 210 rotates to drive the first bevel gear 22 to rotate. The first bevel gear 22 rotates to drive the second bevel gear 23 and the two shaft rods 24 to rotate. The two shaft rods 24 rotate to drive the two worms 25 to rotate. The two worms 25 with opposite threads rotate to drive the two worm wheels 13 to rotate relative to each other. The two worm wheels 13 rotate relative to each other to drive the two support rods 11 on the left and right sides to rotate through the connecting rod 12. Before this process, the control center 10 turns on the auxiliary device 4 and adjusts the position of the second spray plate 47 in the same way as above. In this process, the active The movable block 43 no longer blocks the rectangular groove inside the adjusting rod 44, that is, the second spray plate 47 can operate with half the spraying amount of the first spray plate 31. After that, the two second spray plates 47 are rotated and driven to the two sides of the top of the storage bin 2 by the support rod 11. At this time, the spraying port of the second spray plate 47 is facing the ground, and then the pump 30 is normally turned on to spray the liquid medicine, thereby expanding the spraying range of liquid medicine for liquid fertilizers, etc., which does not need to be sprayed directly on the surface of crops. The amount of liquid medicine sprayed by the two second spray plates 47 is half of that of the first spray plate 31. When the first longitudinal row of spraying is completed, the second spray plate 47 on the left can spray along the spraying area of the second spray plate 47 on the right last time, so that the device can expand the spraying range of the liquid medicine while ensuring that the spraying amount of the liquid medicine in each area is the same, thereby improving the uniformity of the liquid medicine spraying and improving the spraying efficiency of the liquid medicine;

When the drone 1 sprays a suspension-type liquid medicine, it can be stirred by the stirring device 20 to prevent the liquid medicine from settling. Then, the above two spraying methods are selected for spraying according to whether the liquid medicine must be sprayed on the surface of the crops or does not need to be sprayed on the surface of the crops. In this way, the device can change the spraying method according to the type of sprayed liquid, thereby improving the spraying effect of the device and facilitating user use.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
