[0040] The unmanned device comprises an unmanned device body and a spreading device, the spreading device is arranged on the unmanned device body, so as to drive the spreading device to move by the unmanned device body, so that the spreading device can move while spreading the material; taking the unmanned aerial vehicle as an example for description, the unmanned device body can be unmanned aerial vehicle.

[0041] The spreading device comprises a storage mechanism and a spreading mechanism 010 (as shown in Figure 1 ), the spreading mechanism 010 is arranged on the storage mechanism, the storage mechanism is used for storing the material and conveying the material to the spreading mechanism 010 for spreading.

[0042] Optionally, the storage mechanism comprises a material box, the material box is used for storing the material; the material box is provided with a discharge port, the material in the material box can drop from the discharge port under the action of self weight and move to the spreading mechanism 010 for spreading. Of course, in other embodiments, the storage mechanism further comprises a discharging assembly assembled on the material box, and the discharging assembly is arranged at the discharge port and is used for outputting the material in the material box from the discharge port; wherein the discharging assembly includes but is not limited to auger assembly.

[0043] Optionally, please refer to Figure 1 and Figure 2The spreading mechanism 010 comprises a conveying assembly (not shown in the figure), a driving assembly 200 and a flail 300, the driving assembly 200 is arranged on the conveying assembly; the conveying assembly is provided with a discharge port 102, the conveying assembly is used for outputting materials from the discharge port 102, the driving assembly 200 is in transmission cooperation with the flail 300, and is used for driving the flail 300 to rotate around the first axis L1; specifically, the conveying assembly comprises a shell 100 and an auger, the shell 100 is connected with the hopper, the upper side of the shell 100 is provided with a feeding port 101 opposite to and in communication with the discharging port, and the end of the shell 100 is provided with the discharge port 102; the auger is rotatably arranged in the shell 100, and is used for conveying the materials entering the shell 100 to the direction of the discharge port 102 and making the materials drop out of the discharge port 102; the driving assembly 200 is arranged on the shell 100 and is in transmission connection with the flail 300, and is used for driving the flail 300 to rotate, and the flail 300 is distributed opposite to the discharge port 102; when the flail 300 rotates around the first axis L1 under the driving of the driving assembly 200, the flail 300 can throw the materials dropping out of the discharge port 102.

[0044] Further, the shell 100 is provided with a motor in transmission connection with the auger.

[0045] Please refer to Figure 3 In the embodiment, the flail 300 comprises a disc body 400 and a blade 500; the disc body 400 comprises a connecting portion 410 and a throwing portion 420, the connecting portion 410 is in transmission connection with the driving assembly 200, so as to drive the flail 300 to rotate around the first axis L1 under the driving of the driving assembly 200; the blade 500 is arranged on the throwing portion 420 and is used for throwing the materials; wherein the throwing portion 420 is in an arc shape and surrounds the connecting portion 410 at a specific angle, and the specific angle is less than 360°. In this way, the throwing portion 420 is not in a complete circular shape, and the volume of the disc body 400 can be correspondingly reduced, and the number of the blades 500 arranged on the disc body 400 can be reduced, so that the weight of the entire flail 300 is reduced, the load of the driving assembly 200 is reduced, and the cost of preparing the flail 300 is reduced.

[0046] Further, the specific angle is configured to be less than 180°, for example, 179°, 175°, 165°, 160° and the like. In this way, the volume and the weight of the flail 300 can be sufficiently reduced, so that the load of the driving assembly 200 is reduced, the cost of preparing the flail 300 is reduced, and the reliable material throwing effect can be ensured at the same time.

[0047] Of course, in other embodiments, the specific angle can also be greater than or equal to 180°, for example, 180°, 200°, 240° and the like, which is not limited here.

[0048] Further, please refer to Figure 1 andFigure 3 The disc body 400 has a first side and a second side distributed oppositely, the blades 500 are distributed on the first side, and the driving assembly 200 is in transmission connection with the second side. The discharge port 102 is opposite to the first side and is distributed at intervals. In this way, the material output from the discharge port 102 can be reliably hit by the blades 500 connected to the first side of the disc body 400.

[0049] In some embodiments, the driving assembly 200 is configured to drive the disc body 400 to perform a one-way rotation movement, so that the material spread is not symmetrically distributed on the left and right sides of the vertical center line of the spinning disc 300, i.e., the material spread is unevenly distributed.

[0050] Please refer to Figure 2 In this embodiment, the driving assembly 200 is configured to drive the disc body 400 to reciprocate around the first axis L1 in the first direction N1 and the second direction N2. In this way, on the one hand, the problem of uneven spreading caused by the blades 500 being unable to hit the material when the disc body 400 rotates to the upper side of the discharge port 102 and the material falling directly without being hit can be avoided. On the other hand, the material is more evenly hit by the reciprocating blades 500, i.e., the reciprocating spinning disc 300 can evenly hit the material to the left and right sides of the vertical center line of the spinning disc 300, achieving a symmetric spreading width and realizing the uniformity of the material in the spreading width.

[0051] Please refer to Figure 4 and Figure 5The driving assembly 200 comprises a motor 210 and a crank assembly 220, the motor 210 is drivingly connected with the disc body 400 through the crank assembly 220. The structure of the crank assembly 220 can be selected according to requirements. For example, in some embodiments, the crank assembly 220 comprises a rotating disc 221, a protrusion 222 and a track 223, the rotating disc 221 is rotatably arranged in the shell 100 and drivingly connected with the output shaft of the motor 210, the protrusion 222 is connected with the rotating disc 221 and is spacedly distributed with the rotation center of the rotating disc 221; the protrusion 222 is slidably inserted in the sliding groove 224 of the track 223, the end of the track 223 is connected with the disc body 400 and is pivotally connected with the shell 100; when the motor 210 drives the rotating disc 221 to rotate in one direction, the protrusion 222 rotates synchronously with the rotating disc 221, the protrusion 222 reciprocates in the sliding groove 224 of the track 223 and abuts against the groove wall of the sliding groove 224 to drive the track 223 to reciprocate around the end pivotally connected with the shell 100, thereby driving the disc body 400 to reciprocate. Or for example, in other embodiments, the crank assembly 220 comprises a first connecting rod 225, a second connecting rod 226 and a third connecting rod 227, the first end of the first connecting rod 225 is rotatably arranged in the shell 100 and drivingly connected with the output shaft of the motor 210; the second end of the first connecting rod 225 is pivotally connected with the first end of the second connecting rod 226, the second end of the second connecting rod 226 is pivotally connected with the first end of the third connecting rod 227, the second end of the third connecting rod 227 is rotatably arranged in the shell 100 and connected with the disc 300; when the output shaft of the motor 210 rotates in one direction, the first connecting rod 225 is driven to rotate and drives the second connecting rod 226 to swing, thereby driving the third connecting rod 227 and the disc 300 to reciprocate by the second connecting rod 226.

[0052] Please refer to Figure 3 In the embodiment, the disc body 400 is provided with a hollow region 401 for the material to pass through. In this way, a part of the material delivered from the discharge port 102 can directly fall from the hollow region 401, thereby preventing the material from directly impacting the disc 300 in the case of large flow, so that the motor 210 driving the disc 300 to swing is overcurrent protected. Moreover, due to the reciprocating swinging feature of the disc 300, the blades 500 can scatter the material to the left and right sides of the vertical center line of the disc 400, resulting in less material being scattered in the middle. The disc body 400 is provided with the hollow region 401, so that a part of the material can directly fall without being scattered by the blades 500, thereby making the overall scattering effect more uniform and good. On the other hand, the overall weight of the disc 300 can be further reduced, and the load of the motor 210 can be reduced.

[0053] Further, the hollowed region 401 extends through the first side and the second side, for allowing the material to move from the first side to the second side and to freely fall from the second side. In this way, the freely falling material can be prevented from being pushed by the blade 500, thereby ensuring that the middle part of the spinning disc 300 has freely falling material and ensuring the uniformity of the spread material.

[0054] Of course, in other embodiments, the disc body 400 can not be provided with the hollowed region 401.

[0055] Further, the disc body 400 is configured to reciprocally swing in the vertical plane about the first axis L1, and the blade 500 can move below the discharge port 102 when the disc body 400 swings. In this way, the blade 500 can reliably push the material, thereby ensuring the reliability of the material spreading.

[0056] Please refer to Figure 3 In this embodiment, the connecting part 410 is provided with the hollowed region 401; in this way, the material that needs to freely fall from the hollowed region 401 and the material that needs to be pushed by the blade 500 can be prevented from interfering with each other, thereby ensuring the reliability and uniformity of the spreading.

[0057] Of course, in other embodiments, the hollowed region 401 can extend to the pushing part 420; in this way, the lowest point of the hollowed region 401 can be lower, so that the material can more easily pass through the hollowed region 401.

[0058] Further, the connecting part 410 includes the fitting part 411 and at least two connecting parts 412, the first end of the connecting part 412 is connected with the pushing part 420, the second end of the at least two connecting parts 412 is connected with the fitting part 411, and the fitting part 411 is in transmission connection with the driving assembly 200; the at least two connecting parts 412 are spaced apart about the first axis L1 to form the hollowed region 401. In this way, the size of the hollowed region 401 and the structural strength of the disc body 400 can be adjusted by adjusting the size and number of the connecting parts 412, thereby improving the flexibility.

[0059] In this embodiment, the connecting part 410 includes three connecting parts 412, and the three connecting parts 412 are spaced apart about the first axis L1 to form two hollowed regions 401; in this way, not only the range of the material passing through the disc body 400 is increased to ensure the smooth falling of the material in the middle part of the spinning disc 300, but also the structural strength of the disc body 400 is improved.

[0060] Of course, in other embodiments, the number of the connecting parts 412 can also be two, four, etc., which is not specifically limited here.

[0061] The connection between the connecting piece 412, the assembling piece 411 and the dialing part 420, and the connection between the vane 500 and the dialing part 420 can be selected as needed, for example, integrated, welded, etc., which is not limited here.

[0062] Please refer to Figure 3 In the embodiment, the center of the dialing part 420 coincides with the first axis L1, and the flinger 300 includes a plurality of vanes 500, which are connected to the dialing part 420 and are sequentially and spacedly distributed along the length extension direction of the dialing part 420, so that the plurality of vanes 500 are sequentially and spacedly distributed along the preset arc line. In this way, when the dialing part 420 reciprocates around the first axis L1, the plurality of vanes 500 can be used to dial the material more reliably, and the uniformity of the material spreading can be ensured.

[0063] Further, the driving assembly 200 is used to drive the disc body 400 to reciprocate around the first axis L1 on both sides of the second axis L2, and the second axis L2 is perpendicular to the first axis L1; when the disc body 400 is stationary, the center line of the disc body 400 coincides with the second axis L2; a plurality of vanes 500 are distributed on both sides of the center line, and the included angle between at least part of the vanes 500 distributed on one side of the center line and the center line is greater than the included angle between at least part of the vanes 500 distributed on the other side of the center line and the center line; specifically, the dialing part 420 includes a first arc segment 421 and a second arc segment 422 connected to each other, and the connection between the first arc segment 421 and the second arc segment 422 is the center line of the disc body 400; the first arc segment 421 and the second arc segment 422 are both connected with a plurality of vanes 500; wherein the included angle between at least part of the vanes 500 connected to the first arc segment 421 and the center line is greater than the included angle between at least part of the vanes 500 connected to the second arc segment 422 and the center line; wherein the first arc segment 421 is Figure 6 a segment distributed on the left side, and the second arc segment 422 is Figure 6 a segment distributed on the right side, that is, at least one of the plurality of vanes 500 distributed on the left side has an included angle with the center line greater than that of at least one of the plurality of vanes 500 distributed on the right side. Figure 6 Figure 6

[0064] Since the flinger 300 is driven by the crank assembly 220 to reciprocate (for example, left-right direction reciprocation as shown in Figure 6 , the reciprocation of the flinger 300 is a simple harmonic motion, and under the quick-return characteristic of the crank assembly 220, the speed of the flinger 300 when reciprocating left and right will be different, wherein, as shown in Figure 6 , the speed of the flinger 300 when swinging to the left will be slower than that when swinging to the right. Figure 6 ​​The angle between at least one of the plurality of blades 500 on the left side of the middle and the middle line is configured to be greater than the angle between at least one of the plurality of blades 500 on the right side of the middle and the middle line. Figure 6 The angle between at least one of the plurality of blades 500 on the right side of the middle and the middle line is configured to be greater than the angle between at least one of the plurality of blades 500 on the left side of the middle and the middle line. When the disc 300 swings to the right, the swinging speed of the disc 300 is faster. When the blade 500 on the left side of the middle line of the disc 400, which has a greater angle with the middle line, passes below the discharge port 102 to hit the material, the angle between the direction in which the material flies and the horizontal direction is greater, so the material can fly closer. When the disc 300 swings to the left, the swinging speed of the disc 300 is slower. When the blade 500 on the right side of the middle line of the disc 400, which has a smaller angle with the middle line, passes below the discharge port 102 to hit the material, the angle between the direction in which the material flies and the horizontal direction is smaller, so the material flies farther. In this way, the disc 300 that swings back and forth can ensure that the material is more evenly pushed to both sides of the disc 300.

[0065] Further, the angle between the width extension direction of at least part of the blades 500 on one side of the middle line and the middle line is greater than the angle between the width extension direction of at least part of the blades 500 on the other side of the middle line and the middle line. In this way, the disc 300 that swings back and forth under the action of the crank assembly 220 can achieve uniform spreading on both sides by adjusting the angle between the width extension direction of the blades 500 on both sides of the middle line.

[0066] It should be noted that the length extension direction of the blade 500 refers to the direction perpendicular to the surface of the disc 400, and the width extension direction of the blade 500 can refer to the extension direction of the projection of the blade 500 on the surface of the disc 400.

[0067] Alternatively, the angle between at least part of the blades 500 on one side of the middle line and the middle line is greater than the angle between the blades 500 on the other side of the middle line and the middle line. That is, the plurality of blades 500 on both sides of the middle line of the disc 400 are distributed symmetrically about the middle line. The angles between some of the left and right symmetric blades 500 are different, and the angle between some of the left blades 500 and the middle line is greater than the angle between the blades 500 symmetrically distributed on the right side and the middle line. In this way, when the disc 300 swings to the right, the swinging speed of the disc 300 is faster. When the blade 500 on the left side of the middle line of the disc 400, which has a greater angle with the middle line, passes below the discharge port 102 to hit the material, the material flies closer. When the disc 300 swings to the left, the swinging speed of the disc 300 is slower. When the blade 500 on the right side of the middle line of the disc 400, which has a smaller angle with the middle line, passes below the discharge port 102 to hit the material, the material flies farther, ensuring the uniformity of the left and right spreading of the disc 300 that swings back and forth.

[0068] Optionally, the two blades 500 respectively located on two sides of the center line and close to the center line have the same angle with the center line; the angles of the remaining blades 500 distributed on one side of the center line with the center line are all greater than the angles of the remaining blades 500 distributed on the other side of the center line, that is, the angles of the blades 500 located on the left side of the center line of the disc body 400 and close to the center line are equal to the angles of the blades 500 located on the right side of the center line of the disc body 400 and close to the center line, and the angles of the other blades 500 located on the left side of the center line of the disc body 400 are all greater than the angles of the blades 500 symmetrically distributed on the right side of the center line of the disc body 400. In this way, the two blades 500 close to the center line can both push the material to the position close to the second axis L2, thereby ensuring that the material can be pushed not only to the positions far away from the flinger 300 on the left and right sides of the flinger 300, but also to the positions close to the flinger 300, and ensuring the uniformity of the material spreading.

[0069] Optionally, on one side of the center line, the angles of the blades 500 with the center line gradually decrease in the direction away from the center line, that is, on the right side of the center line, the angles of the second blades 500 close to the center line among the blades 500 arranged on the right side of the center line gradually decrease in the direction away from the center line, and the angles of the blades 500 on the left side of the center line gradually decrease in the direction away from the center line. In this way, during the reciprocating swing of the flinger 300, the blades 500 with large angles can be used to push the material to the near position, and the blades 500 with small angles can be used to push the material to the far position, thereby ensuring the uniformity of the spreading.

In this way, during the reciprocating swing of the flinger 300, the blades 500 with large angles can be used to push the material to the near position, and the blades 500 with small angles can be used to push the material to the far position, and the alternating arrangement of the blades 500 with large angles and the blades 500 with small angles can make the material be alternately pushed to the far position and the near position, thereby ensuring the uniformity of the spreading.

[0071] Optionally, on one side of the center line, the intersection points of the extension lines of the width extension directions of the respective blades 500 and the center line are mutually different, i.e., the intersection points of the extension lines of the width extension directions of the respective blades 500 and the center line are sequentially and separately distributed along the length extension direction of the center line. Of course, in other embodiments, the intersection points of the extension lines of the width extension directions of the respective blades 500 and the center line coincide, for example, the intersection points of the extension lines of the width extension directions of the respective blades 500 and the center line all coincide with the oscillation center of the disc body 400.

[0072] Please refer to Figure 6 In the embodiment, the plurality of blades 500 connected to the disc body 400 include a first blade 501, a second blade 502, a third blade 503, and a fourth blade 504. The first blade 501 and the second blade 502 are distributed on the left side of the center line, and the first blade 501 is closer to the center line than the second blade 502.

[0074] Further, the plurality of blades 500 further comprises a fifth blade 505 and a sixth blade 506, the fifth blade 505 is located between the first blade 501 and the second blade 502, and the sixth blade 506 is located between the third blade 503 and the fourth blade 504; wherein the angle between the fifth blade 505 and the center line is greater than the angle between the sixth blade 506 and the center line; the angle between the fifth blade 505 and the center line is greater than the angle between the second blade 502 and the center line, and the angle between the second blade 502 and the center line is greater than the angle between the first blade 501 and the center line; the angle between the sixth blade 506 and the center line is greater than the angle between the fourth blade 504 and the center line, and the angle between the fourth blade 504 and the center line is greater than the angle between the third blade 503 and the center line; wherein the angle between the fifth blade 505 and the center line is 54.5°, and the angle between the sixth blade 506 and the center line is 46.5°.

[0075] Of course, in other embodiments, the angle between the fifth blade 505 and the center line is any value between 53° and 57°, for example: 53°, 54°, 55°, 56°, 57°, etc.; the angle between the sixth blade 506 and the center line is any value between 44° and 48°, for example: 44°, 45°, 46°, 47°, 48°, etc.

[0076] Further, the plurality of blades 500 further comprises a seventh blade 507 and an eighth blade 508, the seventh blade 507 is located on the side of the second blade 502 away from the first blade 501, and the eighth blade 508 is located on the side of the fourth blade 504 away from the first blade 501; the angle between the seventh blade 507 and the center line is greater than the angle between the eighth blade 508 and the center line; the angle between the seventh blade 507 and the center line is less than the angle between the first blade 501 and the center line, and the angle between the first blade 501 and the center line is less than the angle between the second blade 502 and the center line; the angle between the eighth blade 508 and the center line is less than the angle between the third blade 503 and the center line, and the angle between the third blade 503 and the center line is less than the angle between the fourth blade 504 and the center line; wherein the angle between the seventh blade 507 and the center line is 6°, and the angle between the eighth blade 508 and the center line is 5.5°.

[0077] Of course, in other embodiments, the angle between the seventh blade 507 and the center line is any value between 5° and 8°, for example: 5°, 6°, 7°, 8°, etc., and the angle between the eighth blade 508 and the center line is any value between 4° and 6°, for example: 4°, 5°, 6°, etc.

[0078] Please refer to Figure 7The blade 500 comprises two opposite and material-poking surfaces, i.e., a first material-poking surface and a second material-poking surface. When the disc body 400 swings along the first direction N1 about the first axis L1, the first material-poking surface is used to poke the material. When the disc body 400 swings along the second direction N2 about the first axis L1, the second material-poking surface is used to poke the material. The first direction N1 is opposite to the second direction N2. Specifically, the first direction N1 can be leftward, and the second direction N2 can be rightward. In this embodiment, the first material-poking surface and the second material-poking surface are both planar and parallel.

[0079] Please refer to Figure 8 In another embodiment, the first material-poking surface and the second material-poking surface are arranged at an acute angle, and one end of the first material-poking surface and one end of the second material-poking surface are aligned with the outer edge of the poking portion 420. The other end of the first material-poking surface and the other end of the second material-poking surface extend towards the swinging center of the disc body 400. The included angle between the first material-poking surface and the second material-poking surface gradually increases from the end close to the outer edge of the poking portion 420 to the end close to the swinging center of the disc body 400. In this way, the included angle between the two material-poking surfaces of the same blade 500 can be flexibly set to achieve a more uniform material-poking effect.

[0080] Further, the angle between the line connecting the blade 500 and the swing center of the disc body 400 and the first pushing surface is a first angle; the angle between the line connecting the blade 500 and the swing center of the disc body 400 and the second pushing surface is a second angle; along the first direction N1, the angles of the first angles of the plurality of blades 500 gradually decrease, and along the second direction N2, the angles of the second angles of the plurality of blades 500 gradually decrease, for example: the first angle a1 of the seventh blade 507 < the first angle b1 of the second blade 502 < the first angle c1 of the fifth blade 505 < the first angle d1 of the first blade 501 < the first angle e1 of the third blade 503 < the first angle f1 of the sixth blade 506 < the first angle g1 of the fourth blade 504 < the first angle h1 of the eighth blade 508, and the second angle a2 of the eighth blade 508 < the second angle b2 of the fourth blade 504 < the second angle c2 of the sixth blade 506 < the second angle d2 of the third blade 503 < the second angle e2 of the first blade 501 < the second angle f2 of the fifth blade 505 < the second angle g2 of the second blade 502 < the second angle h2 of the seventh blade 507. In this way, when the disc 300 swings to the left, the left pushing surface of each blade 500 is the first pushing surface, and the left pushing surface of each blade 500 is in contact with the material output from the discharge port 102, and the blade 500 with a smaller first angle is in contact with the material first, and pushes the material to a far place, and the blade 500 with a larger first angle is in contact with the material later, and pushes the material to a near place, so that the plurality of blades 500 can scatter the material from far and near, and increase the uniformity of the scattering; the same is true when the disc 300 swings to the right.

[0081] It should be noted that the line connecting the blade 500 and the swing center of the disc body 400 can refer to the line connecting the middle of the end of the blade 500 close to the pushing part 420 and the swing center of the disc body 400.

[0082] Please refer to Figure 9 and Figure 8 In another other embodiment, at least one pushing surface of at least part of the blade 500 is an arc surface, that is, at least one of the first pushing surface and the second pushing surface of at least part of the blade 500 is an arc surface. When the blade 500 rotates with the disc body 400 to a specific angle, the arc-shaped pushing surface has more different contact angles with the material to push the material at multiple angles to improve the uniformity of the pushing.

[0083] Optionally, at least one of the two beating faces of each of the plurality of blades 500 is arc-shaped, for example, the first beating face of each of the plurality of blades 500 is arc-shaped, or the second beating face of each of the plurality of blades 500 is arc-shaped, or the first beating face of a part of the plurality of blades 500 is arc-shaped, and the second beating face of another part of the plurality of blades 500 is arc-shaped. In this way, the arc-shaped beating face can be used to beat the material at multiple angles, thereby improving the uniformity of the material spreading.

[0084] Optionally, referring to Figure 9 , the two beating faces of each of the plurality of blades 500 are arc-shaped, i.e., the first beating face and the second beating face of each of the plurality of blades 500 are arc-shaped. In this way, any one of the beating faces of any one of the plurality of blades 500 has more different contact angles with the material, so as to beat the material at multiple angles, thereby improving the problem of the material being relatively concentrated in some areas after being spread, and further improving the uniformity of the material spreading.

[0085] Optionally, referring to Figure 9 , at least one of the beating faces of at least one of the plurality of blades 500 close to the center line connected to the first arc-shaped section 421 is arc-shaped, and the two beating faces of at least one of the plurality of blades 500 away from the center line connected to the first arc-shaped section 421 are both flat; at least one of the beating faces of at least one of the plurality of blades 500 close to the center line connected to the second arc-shaped section 422 is arc-shaped, and the two beating faces of at least one of the plurality of blades 500 away from the center line connected to the second arc-shaped section 422 are both flat. In this way, the blades 500 located at the middle part of the disc body 400 have at least one arc-shaped beating face, so that when the middle part of the disc body 400 sweeps through the concentrated material falling area in the middle part of the discharge port 102 during the reciprocating swing, the blades 500 with the arc-shaped beating face can be used to fully scatter the densely falling material, thereby improving the uniformity of the spreading.

[0086] Further, at least one of the beating faces of the blade 500 closest to the center line and the second closest to the center line connected to the first arc-shaped section 421 is arc-shaped, and the two beating faces of the remaining blades 500 connected to the first arc-shaped section 421 are both flat; at least one of the beating faces of the blade 500 closest to the center line and the second closest to the center line connected to the second arc-shaped section 422 is arc-shaped, and the two beating faces of the remaining blades 500 connected to the second arc-shaped section 422 are both flat. In this way, the material in the concentrated material falling area of the discharge port 102 can be more reliably scattered.

[0087] Optionally, referring to ​, the two striking surfaces of at least one blade 500 closest to the center line of the plurality of blades 500 connected to the first arc segment 421 are arc surfaces; the two striking surfaces of at least one blade 500 closest to the center line of the plurality of blades 500 connected to the second arc segment 422 are arc surfaces. In this way, the two striking surfaces of the blade 500 located at the middle of the disc body 400 are arc surfaces, and when the middle of the disc body 400 swings in any direction of the first direction N1 and the second direction N2, the arc-shaped striking surfaces can be used to fully scatter the concentrated material falling in the middle of the discharge port 102, thereby improving the uniformity of the spreading.

[0088] Further, the two striking surfaces of the blade 500 closest to the center line and the second blade 500 closest to the center line of the plurality of blades 500 connected to the first arc segment 421 are arc surfaces, and the two striking surfaces of the remaining blades 500 connected to the first arc segment 421 are flat surfaces; the two striking surfaces of the blade 500 closest to the center line and the second blade 500 closest to the center line of the plurality of blades 500 connected to the second arc segment 422 are arc surfaces, and the two striking surfaces of the remaining blades 500 connected to the second arc segment 422 are flat surfaces. In this way, the material in the concentrated falling area can be reliably scattered when the disc body 400 swings in any direction. For example, the two striking surfaces of the seventh blade 507, the second blade 502, the fourth blade 504, and the eighth blade 508 are flat surfaces, and the two striking surfaces of the fifth blade 505, the first blade 501, the third blade 503, and the sixth blade 506 are arc surfaces.

[0089] It should be noted that the spreading device and the spreading mechanism 010 can also be independently provided on a tractor or the like for use, and are not specifically limited here.

[0090] The unmanned device of the present embodiment can be used to spread seed, fertilizer, and other granular materials; in use, the material is stored in the material box, and the material can enter the housing 100 and be output from the discharge port 102 by the auger, and then be scattered by the reciprocating swing flail plate 300.

[0091] In summary, the spreading mechanism 010 of the present application can more uniformly spread the material.

[0092] The above only describes the preferred embodiments of the present application and is not intended to limit the present application.
