[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1As shown, a fertilizing device for a crop protection UAV includes a body 1, a fertilizer box 2 is arranged at the bottom of the body 1, a screen plate 5 is arranged at the bottom of the fertilizer box 2, and an anti-blocking mechanism a is arranged at the bottom of the screen plate 5; a power device 4, the power device 4 is arranged at the bottom of the body 1, and the power device 4 and the anti-blocking mechanism a are linked to each other; wherein, the anti-blocking mechanism a includes two mutually hinged guide components 14, the two guide components 14 are hinged by a rotating shaft a3, and the power device 4 is used to drive the guide component 14 to clear the screen plate 5.

[0023] In this embodiment, when the spreading operation is carried out normally, the anti-blocking mechanism a is in an inverted "V" shape, which is used to divert the fertilizer so that the fertilizer is sprinkled to both sides along the anti-blocking mechanism a. When the sprinkling distance needs to be adjusted, the angle of the anti-blocking mechanism a can be adjusted by the power device 4, so as to control the range of sprinkling on both sides. When the mesh holes of the screen plate 5 are blocked, the power device 4 is operated to drive the anti-blocking mechanism a to continue to move until the anti-blocking mechanism a clears the mesh holes of the screen plate 5. The power device 4 is reset to restore the anti-blocking mechanism a to its initial state. The whole process can be operated without stopping the drone during the spreading operation, and there is no need for the drone to return, thereby improving the spreading efficiency.

[0024] like Figure 2 As shown, a connecting rod 3 is fixedly connected to the bottom of the body 1, and the bottom of the connecting rod 3 is fixedly connected to the fertilizer box 2 through a locking piece.

[0025] In the above manner, the locking member may be a bolt, a buckle or other components, or any other detachable fixing structure. The installed detachable locking member may make it easier to pour fertilizer into or clean out of the fertilizer box 2.

[0026] like Figure 3 As shown, the guide assembly 14 includes an upper cover plate a1 and a lower cover plate a2, and the upper cover plate a1 and the lower cover plate a2 are hinged together with the rotating shaft a3 at a certain angle, and an elastic member a4 is arranged between the upper cover plate a1 and the lower cover plate a2, and the upper cover plate a1 is provided with through holes matching the number of the screen plate 5, and the lower cover plate a2 is provided with a top rod a5 adapted to the through hole, wherein, during normal use, the top of the top rod a5 is flush with the top of the upper cover plate a1.

[0027] In the above manner, when the power device 4 drives the anti-blocking mechanism a to move continuously, the guide assembly 14 in the anti-blocking mechanism a continues to work, and the upper cover plate a1 and the lower cover plate a2 in the guide assembly 14 continue to rotate around the rotating shaft a3. When the upper cover plate a1 rotates to be parallel to the screen plate 5, the upper cover plate a1 does not move, and the lower cover plate a2 then rotates. At this time, the push rod a5 matched with the through holes of the upper cover plate a2 and the screen plate 5 is pushed out, so that the blockage in the screen plate 5 is squeezed out. This operation is repeated, so that the scattering operation can work normally. One point that needs to be explained here is that the elastic member a4 can be any one of a spring and a shrapnel, and a spring is selected here.

[0028] like Figure 3 As shown, the initial angle between the two guide components 14 is less than 180 degrees, and when the guide components 14 are in operation, the angle between the two guide components 14 is 180 degrees.

[0029] In the above method, the two guide components 14 should be less than 180 degrees, so that the fertilizer can pass through the screen plate 5 and be diverted by the two guide components 14 to make the fertilizer evenly sprinkled. When the two guide components 14 are in operation, the guide components 14 rotate upward respectively, so that the angle between the two guide components 14 reaches 180 degrees.

[0030] like Figure 2 As shown, the power device 4 includes a motor 401, and the output shaft 402 of the motor 401 is fixed with two sets of pull ropes 12 through a sleeve. A pulley is provided at the connection of the fertilizer box 2, and the other end of the pull rope 12 passes through the pulley and is connected to the fixed shaft a6 on the lower cover a2.

[0031] In the above manner, when the power device 4 starts to work, the motor 401 therein starts to work, and the output shaft 402 starts to rotate, so that the pull rope 12 is tightened, and the other end of the pull rope 12 is connected to the fixed shaft a6 in the lower cover a2, so that the lower cover a2 rotates upward around the rotating shaft a3.

[0032] like Figure 4 As shown, both the upper cover a1 and the lower cover a2 are provided with hinged brackets, the hinged brackets are staggeredly installed on the rotating shaft a3, and torsion springs are provided at the connection between the hinged brackets and the rotating shaft a3.

[0033] In the above manner, when the power device 4 finishes working, the motor 401 is in a non-working state, and the upper cover a1 and the lower cover a2 return to their initial positions around the rotating shaft a6 under the action of the torsion spring.

[0034] The working principle of the utility model is as follows: when fertilizing the farmland, the prepared fertilizer is poured into the fertilizer box 2, and the UAV body 1 is controlled to fly in the farmland. The fertilizer passes through the screen plate 5 and is evenly spread on the farmland through the guide assembly 14. When the screen plate 5 is blocked, the motor 401 can be quickly controlled to work, so that the output shaft 402 rotates, and the pull rope 12 is tightened around the output shaft 402, thereby pulling up the guide assembly 14 and rotating it upward. When the upper cover plate a1 is flush with the screen plate 5, the lower cover plate a2 continues to rotate, so that the push rod a5 pushes out the upper cover plate a1 and squeezes out the blockage through the screen plate 5. After extrusion, the guide assembly 14 returns to the initial position due to the torsion spring, thereby completing a series of tasks.

[0035] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
