In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
Some embodiments of the present application are described in detail below with reference to the accompanying drawings. Those skilled in the art may combine and combine the features of the different embodiments or examples described in this specification and of the different embodiments or examples without contradiction.
The dispensing apparatus shown in fig. 1 includes a dispensing tray 110 and a magazine 120.
Wherein, material storehouse 120 is used for storing the material, and material storehouse 120 is provided with the unloading unit, and this unloading unit is used for carrying the material to the scattering dish on.
It will be appreciated that the material may be solid particles of seeds, fertiliser, feed or pesticide, as the application is not limited in this regard.
The shape, size and material of the material bin 120 are not limited in the embodiments of the present application. Those skilled in the art may choose or design the device according to actual needs. Illustratively, the upper portion of the material bin 120 may be barrel-shaped, the bottom of the bin may be inverted funnel-shaped, and may be made of plastic material, with stable performance, less deformation, and lighter weight. Still another exemplary embodiment of the material bin 110 may have a box shape at the upper portion and an inverted funnel shape at the bottom, and the material may be a metal material with high strength and stable performance.
In some embodiments, the blanking unit may be provided integrally with the material bin, or the blanking unit may be provided as a separate component below the material bin. However, the materials are led out of the material bin through the blanking unit, and the specific arrangement mode of the blanking unit is not limited in the embodiment of the application.
In some embodiments, a regulating valve may be disposed in the blanking unit, and the regulating valve is used to regulate the quantity and speed of the material passing through.
The spreading disc 110 is used for rotating to generate centrifugal force, so that materials falling on the spreading disc 110 are thrown out under the action of the centrifugal force. Optionally, the spreading disc is connected with a driving device, and the driving device is used for driving the spreading disc to rotate.
Because the rotating speed and the steering of the sowing disc influence the downward throwing inclination angle of the materials, and the sowing disc is controlled to rotate by the driving device, the material sowing width can be effectively adjusted by adjusting the driving parameters of the driving device, the sowing mode is switched and adjustable, and the flexibility of the sowing operation is improved.
In one possible implementation, the distribution plate 110 is disposed horizontally, with its plane of rotation being a horizontal plane.
The seed sowing device using the sowing disc is a mechanical sowing device, and the working principle is that seeds or fertilizer are conveyed from a material bin 120 to the sowing disc 110, and then the sowing disc 110 rotates at a high speed to throw the seeds or fertilizer into farmlands. The sowing tray 110 can be driven by a driving device such as mechanical transmission or hydraulic transmission, the throwing speed of seeds or fertilizer can be adjusted by changing the transmission speed and the diameter of the sowing tray, and the sowing amount is controlled by a blanking unit.
When the seed sowing device is used, the travelling speed and the rotating speed of the seed sowing device are required to be adjusted to achieve the best sowing effect. Secondly, the angle and the spreading range of the spreading disc are required to be adjusted according to the types of crops and the topography conditions, so that seeds or fertilizer can be ensured to uniformly cover the whole farmland. The sowing device with the sowing disc is suitable for sowing large-area crops and fertilizer application, such as wheat, corn, soybean and the like. Its advantages are high sowing speed, large coverage area and uniformity, and suitable for large-scale agricultural production. The control of the sowing width of the sowing device can be realized by adjusting the rotation speed of the sowing disc, the diameter of the sowing disc, the angle of the sowing disc and the height of the sowing disc.
However, when the material is centrifugally scattered, the material is thrown out by the scattering disc to perform parabolic motion. The exit speed and angle of the thrown out objects often lead to overlarge breadth and sparse materials.
In this case, the present application limits the width of the broadcast by adding a cap peak around the periphery of the broadcast disc. The hat brim can limit the outward scattering distance of the materials lifted by the scattering disc, thereby controlling the sowing width.
The application provides a spreading device with a cap peak and an unmanned aerial vehicle, which can effectively limit the width and increase the spreading density of materials.

Wherein, broadcast the width R f The broadcasting frame is needed in the broadcasting process.
In the embodiment of the application, the distance from the sowing disc to the cap peak is far smaller than the sowing width R f The horizontal distance from the center of the sowing disc to the furthest drop point of the material can be used as a sowing width R f The horizontal distance from the impact point of the material and the cap peak to the farthest falling point of the material can also be used as a sowing width R f 。

The included angle beta between the impact speed and the projection of the normal line of the cap peak surface on the XY plane can be calculated as follows:
the material impacts the cap peak and rebounds, the base angle of the cap peak is theta, and the reflection speed is equal to the incidence speed without considering the energy loss in the material rebound process:
the reflecting direction is related to the bottom angle of the cap peak and the incident speed, and the included angle between the reflecting direction of the material and the horizontal plane can be calculated according to the reflecting theoremThe method comprises the following steps:
as shown in figure 6, when the material rebounds from the cap peak, the material will perform parabolic motion with an initial velocity of V and an included angle with the horizontal plane ofAt the moment, the seeds fall onto the ground under the influence of gravity and air resistance, and different sowing widths R can be obtained corresponding to different initial vertical heights H f 。
Assuming that the material is spherical, the diameter of the material is d, the density of the material is ρ, and the gravitational acceleration of the material is g, the air resistance coefficient mu of the material at 25 ℃ under standard atmospheric pressure is:
