[0039] Please refer to Figure 1 This embodiment provides an unmanned device, which may refer to a drone, an unmanned vehicle, etc., and is not specifically limited here.

[0040] The unmanned equipment includes an unmanned equipment body and a spreading device. The spreading device is arranged on the unmanned equipment body so that the spreading device can be driven to move by the unmanned equipment body, so that the spreading device can spread materials while moving. Taking a drone as an example, the unmanned equipment body can refer to an unmanned aerial vehicle.

[0041] The spreading device includes a storage mechanism and a spreading mechanism 010 (such as Figure 1 As shown), the spreading mechanism 010 is arranged in the material storage mechanism, and the material storage mechanism is used to store materials and transport the materials to the spreading mechanism 010 for spreading.

[0042] Optionally, the material storage mechanism includes a material box for storing materials; the material box is provided with a discharge port, and the materials in the material box can fall out from the discharge port under the action of its own weight and move to the sowing mechanism 010 for sowing. Of course, in other embodiments, the material storage mechanism also includes a discharge assembly assembled on the material box, and the discharge assembly is provided at the discharge port, for discharging the materials in the material box from the discharge port; wherein the discharge assembly includes but is not limited to an auger assembly.

[0043] Optionally, see Figure 1 and Figure 2The spreading mechanism 010 includes a conveying assembly (not shown), a driving assembly 200 and a spinning disc 300, wherein the driving assembly 200 is arranged on the conveying assembly; the conveying assembly is provided with a discharge port 102, and the conveying assembly is used to output the material from the discharge port 102, and the driving assembly 200 cooperates with the spinning disc 300 in transmission to drive the spinning disc 300 to rotate around the first axis L1; specifically, the conveying assembly includes a shell 100 and an auger, the shell 100 is connected to the material box, and an inlet port 101 is arranged on the upper side of the shell 100, and the inlet port 101 is opposite to and connected to the discharge port, and the shell A discharge port 102 is provided at the end of the housing 100; the auger is rotatably arranged in the housing 100, and is used for conveying the material entering the housing 100 toward the discharge port 102, and making the material fall out from the discharge port 102; the driving assembly 200 is arranged in the housing 100, and is transmission-connected with the spinner 300, and is used for driving the spinner 300 to rotate, and the spinner 300 is relatively distributed with the discharge port 102; when the spinner 300 rotates around the first axis L1 driven by the driving assembly 200, the spinner 300 can push out the material falling out of the discharge port 102.

[0044] Furthermore, the housing 100 is provided with a motor which is transmission-connected to the auger.

[0045] Please refer to Figure 3 In this embodiment, the spinning tray 300 includes a tray body 400 and blades 500; the tray body 400 includes a connecting portion 410 and a dialing portion 420, the connecting portion 410 is transmission-connected with the driving assembly 200, so as to drive the spinning tray 300 to rotate around the first axis L1 under the drive of the driving assembly 200; the blades 500 are arranged on the dialing portion 420 and are used to dial the material; wherein the dialing portion 420 is arc-shaped, and forms a specific angle around the connecting portion 410, and the specific angle is less than 360°. In this way, the dialing portion 420 is not a complete circle, which can reduce the volume of the tray body 400 accordingly, and can reduce the number of blades 500 arranged on the tray body 400, so as to reduce the weight of the entire spinning tray 300, reduce the load of the driving assembly 200, and reduce the cost of preparing the spinning tray 300.

[0046] Further, the specific angle is configured to be less than 180°, for example, 179°, 175°, 165°, 160°, etc. Such a configuration can fully reduce the volume and weight of the spinner 300 to reduce the load of the drive assembly 200 and reduce the preparation cost of the spinner 300, while ensuring a reliable material spinning effect.

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

[0048] Further, please refer to Figure 1 and Figure 3 The disc body 400 has a first side and a second side that are opposite to each other, the blades 500 are distributed on the first side, and the driving assembly 200 is connected to the second side in a transmission manner; the discharge port 102 is opposite to the first side and is distributed at intervals. In this way, the material discharged from the discharge port 102 can be reliably moved by the blades 500 connected to the first side of the disc body 400.

[0049] In some embodiments, the drive assembly 200 is configured to drive the disc body 400 to perform unidirectional rotational motion, so that the spread material is not symmetrically distributed on the left and right sides of the vertical center line of the spinner 300, that is, the material spread distribution is uneven.

[0050] Please refer to Figure 2 In this embodiment, the driving assembly 200 is configured to drive the disc body 400 to swing back and forth around the first axis L1 along the first direction N1 and the second direction N2; in this way, on the one hand, it can avoid the blade 500 rotating with the disc body 400 to the top of the discharge port 102 and failing to shake the material, resulting in uneven sowing problem in which the material falls directly without being shaken; on the other hand, the reciprocating blades 500 can make the material be shaken out more evenly, that is, the reciprocating swinging spinner 300 can shake the material evenly to the left and right sides of the vertical center line of the spinner 300, thereby achieving symmetrical sowing width and uniformity of the material within the sowing width.

[0051] Please refer to Figure 4 and Figure 5The driving assembly 200 includes a motor 210 and a crank assembly 220, and the motor 210 is drivingly connected to the disk body 400 through the crank assembly 220. The structure of the crank assembly 220 can be selected as needed. For example: in some embodiments, the crank assembly 220 includes a turntable 221, a protrusion 222 and a track 223. The turntable 221 is rotatably disposed on the shell 100 and is drivingly connected to the output shaft of the motor 210. The protrusion 222 is connected to the turntable 221 and is spaced apart from the rotation center of the turntable 221. The protrusion 222 is slidably inserted into the slide groove 224 of the track 223. The end of the track 223 is connected to the disk body 400, and the end is pivotally connected to the shell 100. When the motor 210 drives the turntable 221 to rotate unidirectionally, the protrusion 222 rotates synchronously with the turntable 221. The protrusion 222 reciprocates in the slide groove 224 of the track 223 and abuts against the groove wall of the slide groove 224 to drive the track 223 to swing back and forth around its end pivotally connected to the shell 100, thereby driving the disk body 400 to swing back and forth. Or for example: in some other embodiments, the crank assembly 220 includes 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 disposed on the housing 100, and is transmission-connected to the output shaft of the motor 210; the second end of the first connecting rod 225 is pivotally connected to the first end of the second connecting rod 226, the second end of the second connecting rod 226 is pivotally connected to the first end of the third connecting rod 227, the second end of the third connecting rod 227 is rotatably disposed on the housing 100, and is connected to the spinning disc 300; when the output shaft of the motor 210 rotates in one direction, the first connecting rod 225 is driven to rotate, and the second connecting rod 226 is driven to swing through the first connecting rod 225, thereby utilizing the second connecting rod 226 to drive the third connecting rod 227 and the spinning disc 300 to swing back and forth.

[0052] Please refer to Figure 3 In this embodiment, the plate body 400 is provided with a hollow area 401, and the hollow area 401 is used to allow materials to pass through. In this way, a part of the materials delivered from the discharge port 102 can be directly dropped from the hollow area 401, thereby preventing the material from directly impacting the spinner 300 in the case of a large flow rate, causing the spinner 300 to bear an excessive load, causing the motor 210 that drives the spinner 300 to swing to overcurrent protection; and, due to the reciprocating swinging characteristics of the spinner 300, the blades 500 can scatter the materials to the left and right sides of the vertical center line of the plate body 400, resulting in less materials being spread in the middle. The plate body 400 is provided with a hollow area 401, so that the materials can be directly not passed through the blades 500 and leak a part, so that the overall sowing effect is relatively uniform and good; on the other hand, the overall weight of the spinner 300 can be further reduced, and the load of the motor 210 can be reduced.

[0053] Furthermore, the hollow area 401 runs through the first side and the second side, so as to allow the material to move from the first side to the second side and fall freely from the second side. This arrangement can prevent the freely falling material from being knocked by the blades 500, thereby ensuring that the middle part of the spinner 300 has the freely falling material and ensuring the uniformity of the spreading material.

[0054] Of course, in other embodiments, the disk body 400 may not be provided with the hollow area 401 .

[0055] Furthermore, the disc body 400 is configured to swing back and forth around the first axis L1 in a vertical plane, and the blades 500 can move below the discharge port 102 as the disc body 400 swings. This arrangement ensures that the blades 500 can reliably spread the material, thereby ensuring the reliability of material spreading.

[0056] Please refer to Figure 3 In this embodiment, the connecting portion 410 is provided with a hollow area 401; such a configuration can avoid interference between the material that needs to fall freely from the hollow area 401 and the material that needs to be moved by the blade 500, thereby ensuring the reliability and uniformity of spreading.

[0057] Of course, in other embodiments, the hollow area 401 may extend to the dial portion 420 ; in this way, the lowest point of the hollow area 401 can be made lower, so that materials can pass through the hollow area 401 more easily.

[0058] Furthermore, the connecting part 410 includes an assembly part 411 and at least two connecting parts 412, the first end of the connecting part 412 is connected to the dialing part 420, the second ends of the at least two connecting parts 412 are connected to the assembly part 411, and the assembly part 411 is in driving connection with the driving assembly 200; at least two connecting parts 412 are spaced and distributed around the first axis L1 to form a hollow area 401. In this arrangement, the size and number of the connecting parts 412 can be adjusted to adjust the size of the hollow area 401 and the structural strength of the disk body 400 to improve flexibility.

[0059] In this embodiment, the connecting portion 410 includes three connecting members 412, and the three connecting members 412 are spaced apart around the first axis L1 to form two hollow areas 401; such a configuration not only increases the range in which the material can pass through the disc body 400 to ensure the smooth falling of the material in the middle of the spinner 300, but also improves the structural strength of the disc body 400.

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

[0061] The connection method between the connecting member 412, the assembly member 411 and the dialing part 420, and the connection method between the blade 500 and the dialing part 420 can be selected as needed, such as: integral molding, welding, etc., which is not specifically limited here.

[0062] Please refer to Figure 3 In this embodiment, the center of the dialing portion 420 coincides with the first axis L1, and the spinning disc 300 includes a plurality of blades 500, which are all connected to the dialing portion 420 and are sequentially spaced along the length extension direction of the dialing portion 420, so that the plurality of blades 500 are sequentially spaced along a preset arc. With such a configuration, when the dialing portion 420 reciprocates around the first axis L1, the plurality of blades 500 can be used to more reliably dial the material and ensure uniformity of material spreading.

[0063] Further, the driving assembly 200 is used to drive the disk body 400 to swing back and forth 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; wherein, when the disk body 400 is stationary, the center line of the disk body 400 coincides with the second axis L2; ​​a plurality of blades 500 are distributed on both sides of the center line, and the angle between at least part of the blades 500 distributed on one side of the center line and the center line is greater than the angle between at least part of the blades 500 distributed on the other side of the center line and the center line; specifically, The dialing portion 420 includes a first arc segment 421 and a second arc segment 422 connected to each other, and the connection point between the first arc segment 421 and the second arc segment 422 is the center line of the disk body 400; the first arc segment 421 and the second arc segment 422 are both connected to a plurality of blades 500; wherein the angle between at least part of the blades 500 connected to the first arc segment 421 and the center line is greater than the angle between at least part of the blades 500 connected to the second arc segment 422 and the center line; wherein the first arc segment 421 is Figure 6 The second arc segment 422 is distributed on the left side. Figure 6 The section distributed on the right side, that is, distributed in Figure 6 At least one of the plurality of blades 500 on the left side of the middle has an angle with the center line greater than that of the blades distributed on the left side of the middle line. Figure 6 The multiple blades 500 on the middle right side have an angle with the center line.

[0064] Since the spinning plate 300 is driven by the crank assembly 220 to swing back and forth (such as Figure 6 The reciprocating swing of the impeller 300 is a simple harmonic motion, and under the quick return characteristic of the crank assembly 220, the speed of the impeller 300 when reciprocating left and right is different, wherein, Figure 6 As shown, the speed of the spinning plate 300 swinging to the left is slower than that of the spinning plate 300 swinging to the right. Figure 6At least one of the plurality of blades 500 on the left side of the middle is configured to have an angle greater than that of the middle line. Figure 6 The plurality of blades 500 on the right side of the center have an angle with the center line. When the spinning disc 300 swings to the right, the spinning disc 300 swings faster. When the blades 500 distributed on the left side of the center line of the disc body 400 and having a larger angle with the center line pass under the discharge port 102 to hit the material, the angle between the direction in which the material flies out and the horizontal direction is larger, so the material can fly closer. When the spinning disc 300 swings to the left, the spinning disc 300 swings slower. When the blades 500 distributed on the right side of the center line of the disc body 400 and having a smaller angle with the center line pass under the discharge port 102 to hit the material, the angle between the direction in which the material flies out and the horizontal direction is smaller, so the material flies farther. In this way, it can be ensured that the reciprocating spinning disc 300 can more evenly spread the material to both sides of the spinning disc 300.

[0065] Furthermore, the included angle between the width extension direction of at least part of the blades 500 distributed on one side of the center line and the center line is greater than the included angle between the width extension direction of at least part of the blades 500 distributed on the other side of the center line and the center line. In this way, it is ensured that the spinner 300, which reciprocates under the action of the crank assembly 220, can adjust the included angle between the width extension direction of the blades 500 on both sides of the center line to achieve uniform spreading on both sides.

[0066] It should be noted that the length extension direction of the blade 500 refers to the direction perpendicular to the surface of the disk body 400 , and the width extension direction of the blade 500 may refer to the extension direction of the blade 500 projected on the surface of the disk body 400 .

[0067] Optionally, the angle between at least part of the blades 500 distributed on one side of the midline and the midline is greater than the angle between the blades 500 symmetrically distributed on the other side of the midline and the midline; that is, the multiple blades 500 on the left and right sides of the midline of the disk body 400 are symmetrically distributed along the midline, wherein the angles between some of the left and right symmetrical blades 500 are different, and the angle between some of the left blades 500 and the midline is greater than the angle between the blades 500 symmetrically distributed on the right side and the midline. In this way, when the spinning disc 300 swings to the right, the swinging speed of the spinning disc 300 is faster, and the blades 500 distributed on the left side of the center line of the disc body 400 and having a larger angle with the center line pass under the discharge port 102 to hit the material, causing the material to fly closer. When the spinning disc 300 swings to the left, the swinging speed of the spinning disc 300 is slower, and the blades 500 distributed on the right side of the center line of the disc body 400 and having a smaller angle with the center line pass under the discharge port 102 to hit the material, causing the material to fly farther, thereby ensuring the uniformity of the material spread left and right by the reciprocatingly swinging spinning disc 300.

[0068] Optionally, two blades 500 respectively located on both sides of the center line and both distributed 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 and the center line are greater than the angles of the remaining blades 500 distributed on the other side of the center line and the center line, that is, the angle of the blade 500 located on the left side of the center line of the disk body 400 and close to the center line and the center line is equal to the angle of the blade 500 located on the right side of the center line of the disk body 400 and close to the center line and the center line, and the angles of the other blades 500 located on the left side of the center line of the disk body 400 and the center line are greater than the angles of the blades 500 symmetrically distributed on the right side of the center line of the disk body 400. Such arrangement enables the two blades 500 close to the center line to push the material to a position close to the second axis L2, thereby ensuring that the material can be pushed not only to the left and right sides of the spinner 300 and a position farther away from the spinner 300, but also to a position closer to the spinner 300, thereby ensuring uniformity of material spreading.

[0069] Optionally, on one side of the center line, starting from the second blade 500 close to the center line to the direction away from the center line, the angle between each blade 500 and the center line gradually decreases, that is, on the right side of the center line, the second blade 500 close to the center line among the multiple blades 500 arranged on the right side starts to move away from the center line, and the angle between each blade 500 and the center line gradually decreases. Similarly, on the left side of the center line, the second blade 500 close to the center line among the multiple blades 500 arranged on the left side starts to move away from the center line, and the angle between each blade 500 and the center line gradually decreases. Such a configuration can ensure that during the reciprocating swing of the spinning disc 300, the blade 500 with a large angle is used to move the material to a nearby place, and the blade 500 with a small angle is used to move the material to a distant place, thereby ensuring the uniformity of sowing.

[0070] Optionally, on one side of the center line, the angle between the blade 500 farthest from the center line and the center line is the smallest, and the angle between the blade 500 closest to the center line and the center line is the second smallest, that is, on the right side of the center line, the angle between the blade 500 farthest from the center line among the multiple blades 500 arranged on the right side and the center line is the smallest, and the angle between the blade 500 closest to the center line and the center line is the second smallest. Similarly, on the left side of the center line, the angle between the blade 500 farthest from the center line among the multiple blades 500 arranged on the left side and the center line is the smallest, and the angle between the blade 500 closest to the center line and the center line is the second smallest. With such an arrangement, it can be ensured that during the reciprocating swing of the spinning disc 300, the blade 500 with a large angle is used to move the material to a nearby place, and the blade 500 with a small angle is used to move the material to a distant place, and the blade 500 with a large angle and the blade 500 with a small angle are alternately arranged so that the material is alternately moved to a distant place and a nearby place, thereby ensuring the uniformity of spreading.

[0071] Optionally, on one side of the center line, the intersections of the extension lines of the width extension direction of each blade 500 and the center line do not overlap, that is, the intersections of the extension lines of the width extension direction of each blade 500 and the center line are sequentially spaced along the length extension direction of the center line. Of course, in other embodiments, the intersections of the extension lines of the width extension direction of each blade 500 and the center line overlap, for example: the intersections of the extension lines of the width extension direction of each blade 500 and the center line all overlap with the swing center of the disk body 400.

[0072] Please refer to Figure 6 In this embodiment, the multiple blades 500 connected to the disk body 400 include a first blade 501, a second blade 502, a third blade 503 and a fourth blade 504.

[0074] Furthermore, the plurality of blades 500 also include a fifth blade 505 and a sixth blade 506, wherein 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 from 53° to 57°, for example: 53°, 54°, 55°, 56°, 57°, etc.; the angle between the sixth blade 506 and the center line is any value from 44° to 48°, for example: 44°, 45°, 46°, 47°, 48°, etc.

[0076] Furthermore, the multiple blades 500 also include 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 smaller 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 smaller than the angle between the second blade 502 and the center line; the angle between the eighth blade 508 and the center line is smaller 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 smaller 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 6The blade 500 includes two dialing surfaces that are arranged opposite to each other and are used to dial materials. The two dialing surfaces are respectively a first dialing surface and a second dialing surface. When the disk body 400 swings along the first direction N1 around the first axis L1, the first dialing surface is used to dial materials. When the disk body 400 swings along the second direction N2 around the first axis L1, the second dialing surface is used to dial materials. The first direction N1 is opposite to the second direction N2. Specifically, the first direction N1 may point to the left, and the second direction N2 may point to the right. In this embodiment, the first dialing surface and the second dialing surface are both plane and parallel.

[0079] Please refer to Figure 7 In another embodiment, the width extension direction of the first dialing surface and the width extension direction of the second dialing surface are distributed at an acute angle, and one end of the first dialing surface and one end of the second dialing surface are both aligned with the outer edge of the dialing portion 420, and the other end of the first dialing surface and the other end of the second dialing surface extend toward the swing center of the disk body 400, and the angle between the first dialing surface and the second dialing surface gradually increases from the end close to the outer edge of the dialing portion 420 to the end close to the swing center of the disk body 400. In this way, the angle between the two dialing surfaces of the same blade 500 can be flexibly set to achieve a more uniform material dialing effect.

[0080] Furthermore, the angle between the line connecting the swing center of the blade 500 and the disk body 400 and the first dialing surface is the first angle; the angle between the line connecting the swing center of the blade 500 and the disk body 400 and the second dialing surface is the 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 is less than the first angle b1 of the second blade 502, less than the first angle c1 of the fifth blade 505, less than the first angle c2 of the first blade 501. The first angle d1 is less than the first angle e1 of the third blade 503 and the first angle f1 of the sixth blade 506 is less than the first angle g1 of the fourth blade 504 and the first angle h1 of the eighth blade 508, and the second angle a2 of the eighth blade 508 is less than the second angle b2 of the fourth blade 504 and the second angle c2 of the sixth blade 506 is less than the second angle d2 of the third blade 503 and the second angle e2 of the first blade 501 is less than the second angle f2 of the fifth blade 505 and the second angle g2 of the second blade 502 is less than the second angle h2 of the seventh blade 507. In this way, when the spinning disc 300 swings to the left, the left side of the blade 500 is the first spinning side, and the left side of each blade 500 contacts the material output from the discharge port 102 respectively, and the blade 500 with a small first angle contacts the material first to stir the material to a far place, and the blade 500 with a large first angle contacts the material later to stir the material to a near place, so that multiple blades 500 can scatter the material from far to near, thereby increasing the uniformity of spreading; the same is true when the spinning disc 300 swings to the right.

[0081] It should be noted that the line connecting the blade 500 and the swing center of the disk body 400 may refer to: a line connecting the middle of one end of the blade 500 close to the dialing portion 420 and the swing center of the disk body 400 .

[0082] Please refer to Figure 8 and Fig. 9 In another embodiment, at least one dialing surface of at least part of the blade 500 is an arcuate surface, that is, at least one of the first dialing surface and the second dialing surface of at least part of the blade 500 is an arcuate surface. When the blade 500 rotates to a specific angle with the disk body 400, the arcuate dialing surface has more different contact angles with the material, so that the material can be dialed out at multiple angles to improve the uniformity of dialing.

[0083] Optionally, at least one of the dialing surfaces of all blades 500 is an arcuate surface, for example, the first dialing surfaces of all blades 500 are arcuate surfaces, or the second dialing surfaces of all blades 500 are arcuate surfaces, or the first dialing surfaces of a part of blades 500 are arcuate surfaces, and the second dialing surfaces of another part of blades 500 are arcuate surfaces. In this way, the material can be dialed out at multiple angles by using the arcuate dialing surfaces, thereby improving the uniformity of material spreading.

[0084] Optionally, see Figure 8 , both the two dialing surfaces of all the blades 500 are arc-shaped surfaces, that is, the first dialing surface and the second dialing surface of all the blades 500 are arc-shaped. In this way, any dialing surface of any blade 500 has more different contact angles with the material, so that the material can be dialed out at multiple angles, improving the problem of relative concentration of materials in certain areas after being spread out, and further improving the uniformity of material spreading.

[0085] Optionally, see Fig. 9 , at least one blade 500 near the center line among the multiple blades 500 connected to the first arc segment 421 has at least one dialing surface which is an arc surface, and at least one blade 500 far from the center line among the multiple blades 500 connected to the first arc segment 421 has two dialing surfaces which are both planes; at least one blade 500 near the center line among the multiple blades 500 connected to the second arc segment 422 has at least one dialing surface which is an arc surface, and at least one blade 500 far from the center line among the multiple blades 500 connected to the second arc segment 422 has two dialing surfaces which are both planes. In this way, the blade 500 roughly located in the middle of the disk body 400 has at least one arcuate dialing surface, and when the middle of the disk body 400 sweeps over the falling material concentration area in the middle of the discharge port 102 during the reciprocating swing process, the blade 500 with the arcuate dialing surface can be used to fully disperse the densely falling materials, thereby improving the uniformity of spreading.

[0086] Furthermore, at least one of the curved dialing surfaces of the blade 500 closest to the center line and the second blade 500 closest to the center line among the multiple blades 500 connected to the first arc segment 421, and the two dialing surfaces of the remaining blades 500 connected to the first arc segment 421 are both planes; at least one of the curved dialing surfaces of the blade 500 closest to the center line and the second blade 500 closest to the center line among the multiple blades 500 connected to the second arc segment 422, and the two dialing surfaces of the remaining blades 500 connected to the second arc segment 422 are both planes. With such an arrangement, the materials in the concentrated area of ​​the discharge port 102 can be more reliably dispersed.

[0087] Optionally, see Fig. 9, the two dialing surfaces of at least one blade 500 near the center line among the multiple blades 500 connected to the first arc segment 421 are both arc-shaped surfaces; the two dialing surfaces of at least one blade 500 near the center line among the multiple blades 500 connected to the second arc segment 422 are both arc-shaped surfaces. In this way, the two dialing surfaces of the blades 500 located roughly in the middle of the disk body 400 are both arc-shaped. When the middle of the disk body 400 swings in any direction of the first direction N1 and the second direction N2, when sweeping over the falling material concentration area in the middle of the discharge port 102, the arc-shaped dialing surfaces can be used to fully disperse the densely falling materials, thereby improving the uniformity of spreading.

[0088] Further, the two dialing surfaces of the blade 500 closest to the center line and the second blade 500 closest to the center line among the multiple blades 500 connected to the first arc segment 421 are both arcuate surfaces, and the two dialing surfaces of the remaining blades 500 connected to the first arc segment 421 are both planes; the two dialing surfaces of the blade 500 closest to the center line and the second blade 500 closest to the center line among the multiple blades 500 connected to the second arc segment 422 are both arcuate surfaces, and the two dialing surfaces of the remaining blades 500 connected to the second arc segment 422 are both planes. With such an arrangement, when the disk body 400 swings in any direction, the materials in the concentrated area of ​​falling materials can be reliably scattered. For example, the two dialing surfaces of the seventh blade 507, the second blade 502, the fourth blade 504 and the eighth blade 508 are all planes, and the two dialing surfaces of the fifth blade 505, the first blade 501, the third blade 503 and the sixth blade 506 are all arcuate surfaces.

[0089] It should be noted that the spreading device and the spreading mechanism 010 can also be independently set on a tractor or other equipment for use, and no specific limitation is made here.

[0090] The unmanned equipment of this embodiment can be used for sowing granular materials such as seeds and fertilizers. When in use, the materials are stored in the material box, and the materials can enter the shell 100, and are output from the discharge port 102 through the auger, and then spread out by the reciprocating swinging disc 300.

[0091] In summary, the spreading mechanism 010 of the present invention can spread materials more evenly.
