It should also be understood that on a plane perpendicular to the thickness direction of the bottom wall 113, the shape of the bottom wall 113 of the first groove 112 can be set according to actual needs.

On a plane perpendicular to the rotation direction of the sweeping structure 132, the size of the extension 135 along the gravity direction gradually decreases.

[0054] It should be understood that the main body 134 and the extension portion 135 included in the material sweeping structure 132 in the embodiment of the present application can be integrally formed or separately formed. When the main body 134 and the extension portion 135 are integrally formed, the main body 134 and the extension portion 135 can be formed by stamping, or when the main body 134 and the extension portion 135 are separately formed, the main body 134 and the extension portion 135 can be connected by welding.

[0055] It should also be understood that the attachment of at least a portion of the surface of the extension portion 135 facing the bottom wall 113 to at least a portion of the surface of the bottom wall 113 facing the side of the drone may mean that at least a portion of the surface of the extension portion 135 facing the bottom wall 113 is in direct contact with but not fixedly connected to at least a portion of the surface of the bottom wall 113 facing the side of the drone.

[0056] It should also be understood that, on a plane perpendicular to the rotation direction of the sweeping structure 132 , the gradual reduction in the size of the extension portion 135 along the gravity direction may mean that the size of the extension portion 135 along the gravity direction decreases continuously or discontinuously.

[0057] In the embodiment of the present application, the sweeping structure 132 is configured to include a main body 134 and an extension 135, and the extension 135 is located on a side of the main body 134 close to the bottom wall 113, at least a portion of the surface of the extension 135 facing the bottom wall 113 is attached to at least a portion of the surface of the bottom wall 113 facing the side of the drone, and on a plane perpendicular to the rotation direction of the sweeping structure 132, the size of the extension 135 along the gravity direction gradually decreases, so that when the motor 120 drives the rotating part 130 to rotate, the sweeping structure 132 can smoothly push the material, effectively reducing the risk of the material remaining or accumulating inside the silo part 110, so as to facilitate the normal operation of the spreading device 1, thereby improving the spreading efficiency of the spreading device 1.

[0060] It should also be understood that after the extension portion 136 is bent toward the geometric center of the extension portion 135, the angle of the bent extension portion 136 relative to the gravity direction can be set according to actual needs. As an example, the embodiments of the present application do not limit this.

[0061] It should also be understood that the extension portion 136 and the extension portion 135 may be integrally formed or separately formed. For example, when the extension portion 136 and the extension portion 135 are integrally formed, the extension portion 136 and the extension portion 135 may be formed by stamping.

[0062] In the embodiment of the present application, an extension portion 136 is provided on the outer periphery of the extension portion 135 away from the main body portion 134, and the extension portion 136 is bent in the direction of the geometric center of the extension portion 135, so that the working efficiency of the sweeping structure 132 in pushing the material can be effectively improved, and the risk of the material remaining or accumulating inside the silo component 110 can be reduced, thereby improving the spreading efficiency of the spreading device 1.

[0063] In some implementations, such as Figure 1 and Figure 2 As shown, the spreading device 1 further comprises a baffle component 140 , and the baffle component 140 is located on a side of the silo component 110 away from the drone.

[0064] It should be understood that, on a plane perpendicular to the thickness direction of the baffle member 140 , the orthographic projection of the baffle member 140 may be larger than the orthographic projection of the bottom wall 113 , so as to shield and protect the bottom wall 113 .

[0065] It should also be understood that the shape of the baffle component 140 can be set according to actual needs. For example, on a plane perpendicular to the thickness direction of the baffle component 140, the shape of the baffle component 140 can be set to be circular, rectangular or polygonal, etc.

[0066] In the embodiment of the present application, a baffle component 140 is provided in the spreading device 1, and the baffle component 140 is located on the side of the silo component 110 away from the drone. During the use of the spreading device 1, the damage to the silo component 110 in the spreading device 1 caused by external impact can be effectively reduced, so as to improve the use performance of the spreading device 1.

[0067] Figure 5 A schematic structural diagram of a silo component 110 provided in another embodiment of the present application is shown. Figure 6 A schematic structural diagram of a baffle component 140 provided in another embodiment of the present application is shown.

[0068] In some implementations, such as Figure 1 , 2As shown in Figures 3, 5 and 6, the bottom wall 113 includes a second through hole 115 penetrating the bottom wall 113 along the thickness direction of the bottom wall 113, and the baffle member 140 includes a third through hole 141 penetrating the baffle member 140 along the thickness direction of the baffle member 140. When the spreading device 1 is in an open state, on a plane perpendicular to the thickness direction of the bottom wall 113, at least a portion of the orthographic projection of the second through hole 115 overlaps with at least a portion of the orthographic projection of the third through hole 141; when the spreading device 1 is in a closed state, on a plane perpendicular to the thickness direction of the bottom wall 113, the orthographic projection of the portion of the baffle member 140 other than the third through hole 141 covers the orthographic projection of the second through hole 115.

[0069] It should be understood that the shapes of the second through hole 115 and the third through hole 141 in the embodiment of the present application can be set according to actual needs. For example, on a plane perpendicular to the thickness direction of the bottom wall 113, the shapes of the second through hole 115 and the third through hole 141 can be set to be circular, rectangular or polygonal. It should also be understood that the number of the second through hole 115 and the third through hole 141 can be set to one or more. Specifically, the number of the second through hole 115 and the third through hole 141 can be set according to actual needs. As an example, the embodiment of the present application does not limit this.
