[0007] A receiving ring area is provided in the middle of the slinging disc, and receiving plates are arranged at equal intervals in the receiving ring area. The receiving plates include a receiving surface for guiding the material to move towards the center of the slinging disc. Multiple guide plates are also provided on the outside of the receiving ring area, and each guide plate is evenly distributed on the periphery of the receiving ring area.

[0008] In one embodiment of the spreader, a guide ring area is provided outside the receiving ring area, and multiple first guide plates and multiple second guide plates are provided within the guide ring area.

[0009] The first guide plate has a longer extension length than the second guide plate, and the first guide plate and the second guide plate are alternately distributed in the guide ring area.

[0010] In one embodiment of the spreader, the plates of the first guide plate and the second guide plate are both arranged in an involute shape.

[0011] The projections of the first guide plate and the second guide plate from the center of the swivel disc to the circumference do not coincide;

[0012] A discharge ring area is also provided on the outer ring side of the material guiding ring area. A first discharge baffle and a second discharge baffle are provided in the discharge ring area. The first discharge baffle is connected to the extended end of the first material guiding plate, and the second discharge baffle is connected to the extended end of the second material guiding plate.

[0013] Both the first discharge baffle and the second discharge baffle are arranged to extend radially;

[0014] A first gap ring area is also provided between the discharge ring area and the edge of the sling plate body.

[0015] In one embodiment of the spreader, the guide ring area includes a first guide ring area and a second guide ring area, wherein the second guide ring area is located on the outer ring side of the first guide ring area;

[0016] The plate body of the first guide plate extends from the inner ring edge of the first guide ring area to the outer ring edge of the second guide ring area;

[0017] The second guide plate extends from the inner ring edge of the second guide ring area to its outer ring edge.

[0018] In one embodiment of the spreader, the height of the top edge of both the first guide plate and the second guide plate decreases from the beginning to the end of their extension.

[0019] In one embodiment of the spreader, a second gap ring area is provided between the outer ring edge of the receiving ring area and the inner ring edge of the guiding ring area;

[0020] The distance from the inner edge of the second gap ring area to its outer edge satisfies a preset proportional relationship with the distance from the inner edge of the receiving ring area to its outer edge.

[0021] In one embodiment of the spreader, the receiving surface faces the top side of the discharge cylinder and is inclined.

[0022] The receiving surface is quadrilateral, including a low corner point and a high corner point respectively set at opposite corner positions of the receiving surface;

[0023] The low-position corner point is located near the inner ring edge of the receiving ring area, and the high-position corner point is located near the outer ring edge of the receiving ring area.

[0024] In one embodiment of the spreader, the setting height of the low-position corner point is lower than the maximum setting height of the guide plate;

[0025] The height of the high-position corner point is higher than the maximum height of the guide plate.

[0026] In one embodiment of the spreader, a baffle plate is further included covering the slinger plate.

[0029] Beneficial effects:

[0030] In this invention, a sling plate is installed at the material output end of the feeding cylinder. The sling plate is equipped with a receiving plate and a guide plate. The receiving plate provides initial guidance to the material, causing more material to accumulate near the center of the sling plate, thus redistributing the material near the center and increasing the throwing stroke, which helps to increase the throwing speed. Simultaneously, the guide plates provide a second guidance to the material thrown from the receiving ring area, resulting in a secondary redistribution of the material. This ensures that the material is thrown out relatively evenly in all directions.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] See Figures 1 to 4The present invention provides an exemplary illustration of the spreader and its component structure. The spreader 1 provided by the present invention may include a material discharge cylinder 11 and a throwing disc 12 disposed at the output end of the material discharge cylinder 11. The throwing disc 12 is used to receive the material falling from the material discharge cylinder 11 and throw it to the outside under the centrifugal force generated by the rotation of the throwing disc 12.

[0047] A receiving ring area 121 is provided in the middle of the slinger 12. Receiving plates 1211 are evenly spaced within the receiving ring area 121. More specifically, the receiving plates 1211 are evenly spaced circumferentially around the receiving ring area 121. Each receiving plate 1211 includes a receiving surface for guiding material towards the center of the slinger 12, thereby receiving a portion or all of the material and guiding the received material. Preferably, the receiving surface faces the top side of the discharge cylinder 11 and is inclined. Multiple guide plates 1221 are also provided on the outer side of the receiving ring area 121. These guide plates 1221 are evenly distributed around the periphery of the receiving ring area 121. Correspondingly, material that falls directly onto the upper surface of the throwing disc 12 or is acted upon by the receiving surface leaves the receiving ring area 121 under centrifugal force, and is then guided by the multiple guide plates 1221 to spread the material in various directions. It is understood that the receiving surface can also be a spiral blade with inclined grooves to guide the material closer to the center of the throwing disc 12.

[0048] In this invention, a throwing disc 12 is provided at the material output end of the material discharge cylinder 11. The throwing disc 12 is equipped with a receiving plate 1211 and a guide plate 1221. The receiving surface of the receiving plate 1211 provides initial guidance to the material, causing more material to accumulate near the center of the throwing disc 12, thus redistributing the material near the center of the throwing disc 12 and increasing the throwing stroke of the material on the throwing disc 12, which helps to increase the throwing speed of the material. At the same time, the guide plates 1221 provide a second guidance to the material thrown from the receiving ring area 121, forming a secondary redistribution of the material, so that the material can be thrown out to the outside relatively evenly in all directions.

[0049] The slinger 12 is provided with a guide ring area 122, which is located outside the receiving ring area 121. The guide ring area 122 contains multiple first guide plates 1224 and multiple second guide plates 1225, all vertically oriented. The extension length of the first guide plate 1224 is greater than that of the second guide plate 1225. The first guide plates 1224 and second guide plates 1225 are alternately distributed within the guide ring area 122, ensuring that both are located around the periphery of the receiving ring area 121.

[0050] More specifically, the material guiding ring area 122 may include a first material guiding ring area 1222 and a second material guiding ring area 1223 arranged from the inside out. The first guide plate 1224 extends from the inner edge of the first material guiding ring area 1222 to the outer edge of the second material guiding ring area 1223, while the second guide plate 1225 extends from the inner edge of the second material guiding ring area 1223 to the outer edge of the second material guiding ring area 1223. Both the plates of the first guide plate 1224 and the second guide plate 1225 are arranged in an involute shape, which increases the throwing stroke of the material on the sling plate 12 to the periphery of the sling plate 12. It is understood that in other embodiments, the plates of the first guide plate 1224 and the second guide plate 1225 may also be arranged in a straight line or a spiral.

[0051] Preferably, the projections of the first guide plate 1224 and the second guide plate 1225 from the center of the spinning disc 12 toward the circumference do not coincide, that is, they are in different central angle regions.

[0052] Preferably, the height of the top edge of the first guide plate 1224 and the second guide plate 1225 decreases from the beginning to the end of their extension. Accordingly, materials with high throwing speed or those that bounce off the throwing plate due to collision can be redistributed near the periphery of the throwing plate 122 under the action of gravity.

[0053] like Figure 2 and Figure 3 On the upper surface of the slinger 12, a discharge ring area 123 is also provided on the outer ring side of the guide ring area 122. The discharge ring area is provided with a first discharge baffle 1231 and a second discharge baffle 1232. The first discharge baffle 1231 is connected to the extended end of the first guide plate 1224, and the second discharge baffle 1232 is connected to the extended end of the second guide plate 1225. Both the first discharge baffle 1231 and the second discharge baffle 1232 are arranged in a radial line, that is, the plate extension lines of the two discharge baffles can pass through the rotation center of the slinger 12. Furthermore, a first gap ring area 124 is provided between the discharge ring area 123 and the edge of the throwing disc 12. The first gap ring area 124 allows a certain amount of material to be dispersed in the area after the material is thrown out through the adjacent guide discharge port. This can avoid the situation where there is no material distribution in the circumference of the throwing disc 22 caused by the extension end of the guide plate. The guide discharge port is composed of the extension ends of the adjacent first guide plate 1224 and second guide plate 1225.

[0054] In one embodiment, a second gap ring area 125 may be provided between the outer ring edge of the receiving ring area 121 and the inner ring edge of the guiding ring area 122. The distance from the inner ring edge to the outer ring edge of the second gap ring area 125 satisfies a preset proportional relationship with the distance from the inner ring edge to the outer ring edge of the receiving ring area 121. The guiding gap provided by the second gap ring area 125 allows materials ejected from the receiving ring area 121 to freely distribute within this area, helping to improve the uniformity of material distribution when subsequently entering the guiding ring area.

[0055] like Figures 2 to 4 As shown, the receiving plate 1211 may include a vertical extension section and a receiving extension section. The vertical extension section is perpendicular to the plane where the slinger 12 is located, and the receiving surface is formed on the receiving extension section. Specifically, the receiving surface may be quadrilateral, which may include a low-position corner point L and a high-position corner point H respectively disposed at opposite diagonal positions on the receiving surface. The low-position corner point L is located near the inner ring edge of the receiving ring area 121, and the high-position corner point H is located near the outer ring edge of the receiving ring area 121. Accordingly, after the material falls onto the receiving surface, it can be guided to move towards the inner ring edge of the receiving ring area 121.

[0056] More specifically, the setting height of the low-position corner point L is preferably lower than the maximum setting height of the guide plate 1221, which facilitates guiding the material to a position closer to the center of the slinger 12. And / or, the setting height of the high-position corner point H is higher than the maximum setting height of the guide plate 1221, which facilitates receiving and guiding as much material as possible.

[0057] In the receiving plate 1211, the vertical extension section and the receiving extension section can be integrally formed, and an included angle α is formed between the vertical extension section and the receiving extension section. Furthermore, the seam line between the vertical extension section and the receiving extension section also forms an included angle β with the horizontal plane (or the plane where the sling plate 12 is located). Preferably, the included angle α ranges from 120° to 150°, and the included angle β ranges preferably from 5° to 25°.

[0058] In one embodiment, a baffle plate 13 is provided below the discharge cylinder 11. The baffle plate 13 is used to guide the material thrown out by the throwing disc 12 to collide with the material so that the material spread to the outside can be relatively concentrated in a fixed area below the spreader 1.

[0059] Specifically, such as Figure 1As shown, the baffle 13 covers the throwing disc 12. The baffle 13 may include an annular cavity with an enlarging diameter from top to bottom, and the throwing disc 12 is located at the maximum enlarged diameter of the annular cavity. Of course, in order to make the ejected material more uniform, multiple protrusions for collision can also be provided on the cavity wall of the annular cavity, and the multiple protrusions are evenly distributed circumferentially on the circumferential wall of the annular cavity.

[0060] Combination Figures 1 to 4 The spinning disc 12 is provided with three receiving plates 1211, which are evenly distributed circumferentially within the receiving ring area 121. A connecting hole is also provided at the center of the spinning disc 12 for connecting to the drive shaft that drives the spinning disc 12 to rotate. The guiding ring area 122 is provided with three first guiding plates 1224 and three second guiding plates 1225. The first guiding plates 1224 and second guiding plates 1225 are alternately and spaced apart, and the second guiding plates 1225 can be rotated by a fixed angle, such as 60°, to completely overlap a portion of the first guiding plate 1224.

[0061] This utility model also provides a drone (not shown in the figure), which may include a frame on which the seeder 1 as described above is provided to support the drone to carry out unmanned seeding operations and has good seeding uniformity.

[0062] The spreader 1 may further include a hopper and a conveyor. The hopper includes a discharge port, and the conveyor has an input port that connects to the discharge port and an output port that communicates with the discharge cylinder 11. A drive motor is also provided at the top of the discharge cylinder 11, opposite to the location of the slinger 12. The output shaft of the drive motor is connected to a drive shaft to connect to the slinger 12. Furthermore, a sleeve may be fitted over the drive shaft to prevent direct contact between the material and the drive shaft.

[0063] Finally, it should be noted that the above-described embodiments are merely specific implementations of this utility model, used to illustrate the technical solutions of this utility model, and not to limit it. The protection scope of this utility model is not limited thereto.
