The spreading mechanism includes a conveying component that transports the material horizontally and a vertically rotating disc. The disc includes a disc body and blades connected to the disc body. When the blades rotate with the disc body to the point where they can dissipate the material, spreading can be achieved.

[0005] The embodiments of the present invention are implemented as follows:

The at least two flanges are connected to the outer edge of the disc body and are distributed circumferentially around the disc body, forming a material discharge cavity between two adjacent flanges. The first blades and flanges are connected in a one-to-one correspondence.

[0015] In an optional implementation, when the disc is in a neutral state, the centerline of the disc coincides with the second axis; the first blade is closer to the centerline than the second blade; and both sides of the centerline have flanges so that there is a material discharge cavity at the position corresponding to the centerline.

[0016] In an optional implementation, when the disk body is in a neutral state, the centerline of the disk body coincides with the second axis; the first blade is closer to the centerline than the second blade; and / or, the second axis is perpendicular to the first axis.

[0017] In an optional embodiment, the swivel disc includes a plurality of first blades, and a plurality of first blades are distributed on both sides of the center line. The angle between at least a portion of the first blades distributed on one side of the center line and the center line is greater than the angle between at least a portion of the first blades distributed on the other side of the center line and the center line.

[0018] In an optional implementation, at least a portion of the first blades distributed on one side of the centerline form an angle with the centerline that is greater than the angle with the centerline formed by the first blades symmetrically distributed on the other side of the centerline.

[0019] In an optional embodiment, the swivel disc includes at least two first blades and at least two second blades, with the first blades and second blades distributed on both sides of the center line; the first blades distributed on either side of the center line are closer to the center line than the second blades distributed on the same side of the center line.

[0020] In an optional embodiment, a plurality of second blades are distributed on both sides of the centerline, and the angle between at least a portion of the second blades distributed on one side of the centerline and the centerline is greater than the angle between at least a portion of the second blades distributed on the other side of the centerline and the centerline.

[0021] In an optional implementation, at least a portion of the second blades distributed on one side of the centerline form an angle with the centerline that is greater than the angle with the centerline formed by the second blades symmetrically distributed on the other side of the centerline.

[0022] In an optional implementation, multiple first blades and multiple second blades are distributed on both sides of the centerline;

[0023] On one side of the centerline, the angle between the first blade closest to the centerline and the centerline is smaller than the angle between the second blade closest to the centerline and the centerline. The angle between the second blade closest to the centerline and the centerline is at least greater than the angle between one of the second blades on the same side and the centerline. The angle between the first blade closest to the centerline and the centerline is greater than the angle between the second blade closest to the centerline and the centerline.

[0024] In an optional implementation, the dispensing mechanism further includes at least two fasteners, through which the disk body is connected to the drive assembly; and / or,

[0025] The drive assembly and the disk are connected by a tapered spline.

[0026] In a second aspect, the present invention provides a spreading device, including a storage mechanism and a spreading mechanism according to any of the foregoing embodiments, wherein the spreading mechanism is disposed in the storage mechanism, and the storage mechanism is used to store materials and to transport the materials to the spreading mechanism for spreading.

[0027] Thirdly, the present invention provides an unmanned device, including a spreading mechanism or a spreading device according to any of the foregoing embodiments.

[0028] The beneficial effects of the spreading mechanism in this embodiment of the invention include: the spreading mechanism provided in this embodiment of the invention includes a driving mechanism and a swivel disc, wherein the swivel disc can reciprocate around a first axis and on both sides of a second axis under the drive of the driving mechanism, so that the first blade and the second blade of the swivel disc can push the material out during the swivel process, thereby achieving the purpose of spreading the material; wherein, the first blade has a first end close to the first axis and a second end far from the first axis, and the second blade has a third end close to the first axis and a fourth end far from the first axis, and the distance between the second end and the first axis is greater than the distance between the fourth end and the first axis; in this way, the second end of the first blade far from the first axis extends outward relative to the fourth end of the second blade far from the first axis. When the disc drives the first blade and the second blade to oscillate, the linear velocity of the second end of the first blade (i.e., the far end of the first blade relative to the first axis) is increased relative to the linear velocity of the fourth end of the second blade (i.e., the far end of the second blade relative to the first axis), thereby enabling the far end of the first blade to push the material further, thereby increasing the spreading width of the spreading mechanism.

[0029] The spreading device and unmanned equipment of the present invention include all the beneficial effects of the aforementioned spreading mechanism, such as: using the far end of the first blade to spread the material further, increasing the spreading width of the spreading device, and improving the material spreading efficiency of the unmanned equipment, which helps to reduce the number of times the unmanned equipment moves during operation.

[0038] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0040] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0041] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] This embodiment provides an unmanned device, which may refer to drones, unmanned vehicles, etc., and is not specifically limited here.

[0043] Unmanned equipment includes the unmanned equipment body and the spreading device. The spreading device is set on the unmanned equipment body so that the unmanned equipment body can drive the spreading device to move, 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.

[0044] The spreading device includes a storage mechanism and a spreading mechanism. The spreading mechanism is located in the storage mechanism, which is used to store materials and to transport the materials to the spreading mechanism for spreading.

[0045] Optionally, the storage mechanism includes a hopper for storing materials; the hopper has a discharge port, allowing the materials inside to fall out under their own weight and move to the spreading mechanism for spreading. In other embodiments, the storage mechanism further includes a discharge assembly mounted on the hopper, located at the discharge port, for discharging the materials from the hopper; the discharge assembly includes, but is not limited to, an auger assembly.

[0046] Optionally, the spreading mechanism includes a conveying assembly (not shown), a drive assembly, and a dispensing disc 010 (such as...). Figure 1 As shown, the drive component is disposed on the conveying component; the conveying component is provided with a discharge port, and the conveying component is used to output materials from the discharge port. The drive component is driven and cooperates with the slinger 010 to drive the slinger 010 to rotate around the first axis L1; wherein, the conveying component includes a housing, an auger and a motor. The housing is connected to the material box. The upper side of the housing is provided with an inlet, which is opposite to and connected to the discharge port. The end of the housing is provided with a discharge port; the auger is rotatably disposed in the housing. The motor is disposed in the housing and is driven and connected to the auger. The motor drives the auger to rotate, which can convey the materials entering the housing towards the discharge port and make the materials fall out of the discharge port; the drive component is disposed in the housing and is driven and connected to the slinger 010 to drive the slinger 010 to rotate. The slinger 010 is distributed opposite to the discharge port; when the slinger 010 rotates around the first axis L1 under the drive of the drive component, the slinger 010 can push the materials falling out of the discharge port out.

[0047] Please refer to Figure 1 and Figure 2 In this embodiment, the spinning disc 010 includes a disc body 100 and blades disposed on the disc body 100. The disc body 100 includes a connecting portion 150 and a dialing portion 160. The connecting portion 150 is connected to a drive assembly to drive the spinning disc 010 to rotate around a first axis L1 under the drive of the drive assembly. The blades are connected to the dialing portion 160 and are used to dial materials. The dialing portion 160 is arc-shaped and surrounds the connecting portion 150 at a specific angle, which is less than 360°. With this configuration, the dialing portion 160 is not a complete circle, which can correspondingly reduce the volume of the disc body 100 and reduce the number of blades disposed on the disc body 100, thereby reducing the weight of the entire spinning disc 010, reducing the load on the drive assembly, and lowering the cost of manufacturing the spinning disc 010.

[0048] Furthermore, specific angles are configured to be less than 180°, such as 179°, 175°, 165°, 160°, etc. This setting can significantly reduce the size and weight of the spinning disc 010, thereby reducing the load on the drive components and lowering the manufacturing cost of the spinning disc 010, while simultaneously ensuring reliable material feeding.

[0049] Of course, in other embodiments, the specific angle may be greater than or equal to 180°, such as 180°, 200°, 240°, etc.; or, in other embodiments, the dialing part 160 may be configured as a complete circle, which is not specifically limited here.

[0050] Furthermore, please refer to Figure 3 The disc body 100 has a first side 101 and a second side 102 that are distributed opposite to each other. Blades are distributed on the first side 101, and a drive assembly is connected to the second side 102. The discharge port is opposite to the first side 101 and is distributed at intervals. This arrangement enables the material output from the discharge port to be reliably driven by the blades connected to the first side 101 of the disc body 100.

[0051] Alternatively, please refer to Figure 2 and Figure 3 The second side 102 of the disc body 100 is connected with a reinforcing rib 103 to increase the structural strength of the disc body 100.

[0052] In some implementations, the drive assembly is configured to drive the disc 100 to rotate in one direction. As a result, the spread material is not symmetrically distributed on the left and right sides of the vertical center line of the disc 010, that is, the material spread distribution is uneven.

[0053] Please refer to Figure 1 and Figure 4 In this embodiment, the driving component is configured to drive the disk 100 to reciprocate around the first axis L1 and the second axis L2 along the first direction N1 and the second direction N2 on both sides of the second axis L2. The first axis L1 is perpendicular to the second axis L2. In this way, on the one hand, it can avoid the problem of uneven spreading caused by the blades rotating above the discharge port as the disk 100 rotates and failing to dissipate the material, resulting in the material falling directly without being dissipated. On the other hand, the reciprocating blades make the material more evenly dissipated. That is, the reciprocating disk 010 can evenly dissipate the material to the left and right sides of the vertical center line of the disk 010, achieving symmetrical spreading and uniformity of the material within the spreading range.

[0054] It should be understood that in other embodiments, the angle between the first axis L1 and the second axis L2 can be other angles, such as 88°, 95°, etc., which are not specifically limited here.

[0055] Furthermore, the drive assembly includes a motor and a crank-connecting rod assembly (the crank-connecting rod assembly can also be a reciprocating oscillating mechanism), with the motor connected to the disc body 100 via the crank-connecting rod assembly. The structure of the crank-connecting rod assembly is similar to related technologies and will not be described in detail here; when the output shaft of the motor rotates unidirectionally in a preset direction, it can drive the swivel disc 010 to reciprocate around the first axis L1 on both sides of the second axis L2 via the crank-connecting rod assembly.

[0056] Furthermore, the crank-connecting rod assembly is connected to the connecting part 150 via a tapered spline; specifically, please refer to... Figure 5 The connecting part 150 is provided with a insertion hole 210, which is distributed on the second side 102 of the disc body 100. The insertion hole 210 is adapted to the tapered spline, which is fixedly connected to the crank connecting rod assembly and inserted into the insertion hole 210. By using the tapered spline as a connecting part, the problems of tight fit being unsuitable for assembly due to spline dimensional tolerances, and loose fit having assembly gaps leading to play in the assembly, which can easily cause wear after long-term operation, resulting in increasingly larger play gaps and other assembly instability issues.

[0057] Because the material ejector plate 010 experiences significant impact loads when ejecting materials, to ensure the stability of the connection between the ejector plate 010 and the drive assembly and to improve the anti-loosening performance of the ejector plate 010, please refer to... Figure 4 The spreading mechanism in this embodiment includes two fasteners 200. The disc body 100 is fixedly connected to the drive assembly via the two fasteners 200. Specifically, the connecting part 150 is fixedly connected to the drive assembly via the two fasteners 200, and the two fasteners 200 are symmetrically distributed about the first axis L1. The fasteners 200 include, but are not limited to, screws and bolts.

[0058] Optionally, the connecting part 150 is fixedly connected to the drive assembly by two fasteners 200. Specifically, the connecting part 150 is fixedly connected to the crank connecting rod assembly or the tapered spline by two fasteners 200.

[0059] It should be understood that in other embodiments, the number of fasteners 200 connecting the disk body 100 and the drive assembly may be one, three, four, etc., and no specific limitation is made here.

[0060] Of course, in other embodiments, the drive assembly may consist of only a motor, the output shaft of which is connected to the connection portion 150 of the disc body 100, and the swivel disc 010 is driven to swing back and forth around the first axis L1 on both sides of the second axis L2 by the forward and reverse rotation of the output shaft of the motor.

[0061] Furthermore, in this embodiment, the motor's output shaft is connected to the connecting portion 150 via a tapered spline; specifically, the connecting portion 150 is provided with a insertion hole 210, which is adapted to the tapered spline. The tapered spline is fixedly connected to the motor's output shaft and inserted into the insertion hole 210. Further still, the connecting portion 150 can be fixedly connected to the tapered spline or the motor's output shaft via a fastener 200.

[0062] Please refer to Figure 4In this embodiment, the disc body 100 is provided with a hollow area 104, which is used to allow material to pass through. In this way, a portion of the material conveyed from the discharge port can fall directly through the hollow area 104, thereby preventing the material from directly impacting the swivel disc 010 under high flow conditions, causing the swivel disc 010 to bear excessive load and triggering the overcurrent protection of the motor driving the swivel disc 010. Moreover, due to the reciprocating swivel characteristics of the swivel disc 010, the blades can scatter the material to the left and right sides of the vertical center line of the disc body 100, resulting in less material being spread in the middle. The hollow area 104 of the disc body 100 allows some material to pass through without being brushed by the blades, thus making the overall spreading effect more uniform and better. Furthermore, it can further reduce the overall weight of the swivel disc 010 and reduce the motor load.

[0063] Furthermore, the perforated area 104 extends through the first side 101 and the second side 102, allowing material to move from the first side 101 to the second side 102 and fall freely from the second side 102. This arrangement prevents the freely falling material from being knocked away by the blades, thereby ensuring that the center of the dispensing disc 010 contains freely falling material and ensuring the uniformity of the spread material.

[0064] Of course, in other embodiments, the disk body 100 may not have a cutout area 104.

[0065] Furthermore, the disc 100 is configured to reciprocate about a first axis L1 in a vertical plane, and the blades can move below the discharge port as the disc 100 oscillates. This configuration ensures that the blades can reliably dispense material, thereby ensuring the reliability of material dispensing.

[0066] Please refer to Figure 4 In this embodiment, the connecting part 150 is provided with a hollow area 104; this arrangement can avoid interference between the material that needs to fall freely from the hollow area 104 and the material that needs to be pushed by the blades, thereby ensuring the reliability and uniformity of the spreading.

[0067] Of course, in other embodiments, the cutout area 104 may extend to the dialing part 160; in this way, the lowest point of the cutout area 104 can be lowered, so that the material can pass through the cutout area 104 more easily.

[0068] Furthermore, the connecting portion 150 includes a mounting part 151 and at least two connecting members 152. One end of each connecting member 152 is connected to the dialing part 160, and the other ends of both connecting members 152 are connected to the mounting part 151. The mounting part 151 is connected to the drive assembly. The at least two connecting members 152 are spaced apart around the first axis L1 to form a hollow area 104. This arrangement allows for adjustment of the size of the hollow area 104 and the structural strength of the disc body 100 by adjusting the size and number of the connecting members 152, thereby improving flexibility.

[0069] It should be noted that the connection between the aforementioned connecting part 150 and the crank-connecting rod assembly can refer to the connection of the assembly 151 to the crank-connecting rod assembly; specifically, the assembly 151 is connected to the crank-connecting rod assembly via a tapered spline, and the assembly 151 can be connected to the crank-connecting rod assembly or the tapered spline via a fastener 200. The connection between the aforementioned connecting part 150 and the motor output shaft can refer to the connection of the assembly 151 to the motor output shaft; wherein, the assembly 151 is connected to the motor output shaft via a tapered spline, and the assembly 151 can be connected to the motor output shaft or the tapered spline via a fastener 200.

[0070] In this embodiment, the connecting part 150 includes three connectors 152, which are distributed at intervals around the first axis L1 to form two hollow areas 104. This arrangement not only increases the range through which materials can pass through the disc body 100 to ensure the smooth drop of materials in the middle of the throwing disc 010, but also improves the structural strength of the disc body 100.

[0071] Of course, in other embodiments, the number of connectors 152 may be two, four, etc., and no specific limitation is made here.

[0072] The connection method between connector 152, mounting part 151 and dialing part 160, and the connection method between blade and dialing part 160 can be selected as needed, such as integral molding, welding, etc., and no specific limitation is made here.

[0073] To increase the spreading range of the seeding mechanism and thus improve spreading efficiency; please refer to Figure 4In this embodiment, the center of the dialing part 160 coincides with the first axis L1, and the swivel disc 010 includes multiple blades, among which are a first blade 110 and a second blade 120. The swivel disc 010 also includes a flange 130, which is connected to the outer edge of the disc body 100. Specifically, the flange 130 is connected to the outer edge of the dialing part 160, that is, the flange 130 is connected to the side of the dialing part 160 away from the connector 152. The first blade 110 is connected to the flange 130, and the second blade 120 is connected to the dialing part 160 of the disc body 100. The first blade 110 and the second blade 120 are spaced apart along the length extension direction of the dialing part 160, so that the first blade 110 and the second blade 120 are sequentially spaced apart along a preset arc. 0 is connected to the drive assembly, and the drive assembly is used to drive the disc 100 to reciprocate around the first axis L1 on both sides of the second axis L2, so that the first blade 110 and the second blade 120 swing synchronously with the disc 100 and can push out the material output from the discharge port; wherein, when the disc 100 is in a neutral state, the center line of the disc 100 coincides with the second axis; the first blade 110 is closer to the center line than the second blade 120; the first blade 110 has a first end 111 close to the first axis and a second end 112 away from the first axis, the second blade 120 has a third end 121 close to the first axis and a fourth end 122 away from the first axis, and the distance between the second end 112 and the first axis is greater than the distance between the fourth end 122 and the first axis. In this way, the second end 112 of the first blade 110, which is away from the first axis, extends outward from the disk body 100 relative to the fourth end 122 of the second blade 120, which is away from the first axis. When the disk body 100 drives the first blade 110 and the second blade 120 to swing, the linear velocity of the second end 112 of the first blade 110 (i.e., the far end of the first blade 110 relative to the first axis) increases relative to the linear velocity of the fourth end 122 of the second blade 120 (i.e., the far end of the second blade 120 relative to the first axis). This allows the far end of the first blade 110 to spread the material further, thereby increasing the spreading width of the spreading mechanism and improving the material spreading efficiency of the unmanned equipment, which is beneficial to reducing the number of times the unmanned equipment moves during operation.

[0074] It should be understood that in other embodiments, the swivel disc 010 does not include the flange 130, the first blade 110 is only connected to the disc body 100, and the second end 112 of the first blade 110 can extend from the outer edge of the disc body 100; or, in other embodiments, the swivel disc 010 does not include the flange 130, the first blade 110 is only connected to the disc body 100, and the outer edge of the disc body 100 is widened so that the second end 112 of the first blade 110 is connected to the disc body 100, and the second end 112 of the first blade 110 is connected to the disc body 100 and is flush with the outer edge of the disc body 100.

[0075] It should also be understood that in other embodiments, the second blade 120 is closer to the centerline of the disk body 100 relative to the first blade 110.

[0076] Optionally, the first blade 110 extends to connect with the disc body 100; specifically, the first blade 110 extends to connect with the dispensing unit 160; the length H1 of the orthographic projection of the first blade 110 on the setting plane a is greater than the length H2 of the orthographic projection of the second blade 120 on the setting plane a; wherein the setting plane a coincides with or is parallel to the disc body 100. This configuration increases the length of the first blade 110, allowing it to contact and dispense more material, thereby improving the efficiency and uniformity of material dispensing and preventing material output from the outlet from clogging between the conveying assembly and the dispensing disc 010.

[0077] Of course, in other embodiments, the disk body 100 does not have a flange 130, the first blade 110 is connected to the outer edge of the disk body 100, and the length H1 of the orthographic projection of the first blade 110 on the set plane a can be equal to or less than the length H2 of the orthographic projection of the second blade 120 on the set plane a, as long as the distance between the second end 112 of the first blade 110 and the first axis is greater than the distance between the fourth end 122 of the second blade 120 and the first axis.

[0078] It should be noted that when the disc body 100 is in the assembled and usable state, both the disc body 100 and the set plane a are vertical planes; the second axis L2 extends vertically. In this way, when the drive assembly drives the swivel disc 010 to swing, the swivel disc 010 swings within the vertical plane to ensure efficient material spreading. Specifically, the aforementioned centerline can refer to the axis of symmetry of the disc body 100.

[0079] It should be understood that in other embodiments, when the disk body 100 is in the assembled state, the disk body 100 and the set plane a can also be horizontal planes, which are not specifically limited here.

[0080] The vertical and horizontal planes mentioned above are relative terms for "vertical" or "horizontal," not absolute terms for "vertical" or "horizontal."

[0081] It should also be noted that connecting the first blade 110 to the flange 130 allows the flange 130 to support the first blade 110, reducing the load on the first blade 110 when dispensing material. Compared to not adding the flange 130, simply increasing the length of the first blade 110 and connecting a portion of the first blade 110 to the dispensing part 160 while the other portion extends out relative to the dispensing part 160, and then adding the flange 130 to connect the first blade 110, the stability and reliability of the first blade 110 are enhanced, ensuring the reliability of material dispensing and a longer service life for the dispensing disc 010. Moreover, compared to directly increasing the width of the dispensing part 160 to support the longer first blade 110, connecting the flange 130 to the outer edge of the dispensing part 160 to support the longer first blade 110 reduces the overall weight of the dispensing disc 010, thereby reducing the load on the motor driving the dispensing disc 010 and reducing the input of raw materials for manufacturing the dispensing disc 010, which helps to reduce costs.

[0082] It should be understood that in other embodiments, the first blade 110 is only connected to the flange 130 and does not extend to the dialing part 160.

[0083] Alternatively, please refer to Figure 4 The width w of the orthographic projection of the first blade 110 onto the set plane a is less than the width of the orthographic projection of the flange 130 onto the set plane a; setting the width of the flange 130 to be greater than that of the first blade 110 ensures that the flange 130 reliably supports the first blade 110, thus ensuring the stability and reliability of the first blade 110 and the reliability of material spreading.

[0084] Alternatively, please refer to Figure 4 and Figure 5 The flange 130 and the disc 100 extend in the same plane; both the flange 130 and the disc 100 coincide with or are parallel to the designated plane a. When the disc 100 is in the assembled state, the disc 100 and the flange 130 are in the same vertical plane. This arrangement avoids interference from either the disc 100 or the flange 130 when the first blade 110 and the second blade 120 dispense materials, thus ensuring the reliability of material dispensing.

[0085] Alternatively, please refer to Figure 4The swivel disc 010 includes at least two flanges 130 and at least two first blades 110. The at least two flanges 130 are connected to the outer edge of the disc body 100 and are distributed circumferentially around the disc body 100. That is, the at least two flanges 130 are connected to the side of the dialing part 160 away from the connector 152 and are distributed circumferentially around the extension direction of the dialing part 160. A material discharge cavity 140 is formed between two adjacent flanges 130, and the first blades 110 are connected to the flanges 130 in a one-to-one correspondence. A portion of the material output from the discharge port is dispersed by the first blade 110 and / or the second blade 120, while the other portion falls under its own weight without being dispersed by the blades. This results in at least two flanges 130 being spaced apart, and a material drop cavity 140 being formed between two adjacent flanges 130. This ensures that the material not dispersed by the blades falls reliably without being blocked by the disc 100 and the flanges 130. In other words, the material drop cavity 140 between two adjacent flanges 130 improves the material blockage problem caused by material accumulation.

[0086] Furthermore, both sides of the center line have flanges 130, so that there is a material discharge cavity 140 at the position corresponding to the center line. With this configuration, when the center line of the swivel disc 010 swings to coincide with the second axis L2, it can be ensured that part of the material falling from the discharge port can fall freely from the space between the two first blades 110, effectively improving the material blockage problem.

[0087] For example, the slinger 010 of this embodiment includes four flanges 130 and four first blades 110. The four flanges 130 are all connected to the side of the dialing part 160 away from the connector 152 and are spaced apart along the extending direction of the dialing part 160, forming three material discharge cavities 140. The four first blades 110 are connected one-to-one with the four flanges 130, and two flanges 130 are distributed on each side of the center line. This arrangement ensures that the slinger 010 has a larger spreading width, improves the uniformity of spreading, and avoids material blockage.

[0088] It should be understood that the two flanges 130 furthest from the center line and the two ends of the dialing part 160 furthest from the center line are distributed at intervals to form a cavity for material dropping between the flanges 130 furthest from the center line and the corresponding ends of the dialing part 160 furthest from the center line, so as to further improve the problem of material blockage in the throwing disc 010.

[0089] Of course, in other embodiments, the number of flanges 130 and first blades 110 can be one, two, three, five, six, etc., and no specific limitation is made here.

[0090] Alternatively, please refer to Figure 4Multiple flanges 130 and multiple first blades 110 are distributed on both sides of the center line, and the angle between at least a portion of the first blades 110 on one side of the center line and the center line is greater than the angle between at least a portion of the first blades 110 on the other side of the center line and the center line. Specifically, the dialing unit 160 includes a first arc-shaped segment 161 and a second arc-shaped segment 162 connected to each other, and the connection point of the first arc-shaped segment 161 and the second arc-shaped segment 162 is the center line of the disc body 100; both the first arc-shaped segment 161 and the second arc-shaped segment 162 are connected to multiple flanges 130 and multiple first blades 110; wherein, the angle between at least a portion of the first blades 110 connected to the first arc-shaped segment 161 and the center line is greater than the angle between at least a portion of the first blades 110 connected to the second arc-shaped segment 162 and the center line; wherein, the first arc-shaped segment 161 is... Figure 4 The middle section is located on the left side, and the second arc segment 162 is... Figure 4 The middle section is distributed on the right side, that is, distributed in Figure 4 At least one of the multiple first blades 110 on the left side of the middle section forms an angle with the centerline that is greater than that distributed on the left side of the middle section. Figure 4 The angle between one of the multiple first blades 110 on the right side and the centerline.

[0091] Because the swivel disc 010 reciprocates around the first axis L1 on both sides of the second axis L2, and in particular, in some embodiments, the swivel disc 010 is driven by a crank-connecting rod assembly to oscillate reciprocally (e.g. Figure 4 The reciprocating oscillation of the slinger 010 (which swings left and right) is a simple harmonic motion. Due to the quick-return characteristic of the reciprocating oscillation, the slinger 010 will have different speeds during its left and right reciprocating oscillations. For example... Figure 4 As shown, the speed at which the swivel disc 010 swings to the left will be slightly slower than its speed to the right, and it will be distributed across... Figure 4 At least one of the multiple first blades 110 on the left side is configured to form an angle with the centerline that is greater than that distributed on the left side. Figure 4 The angle between at least one of the multiple first blades 110 on the right side and the centerline determines the distance the material travels. When the swivel disc 010 swings to the right, its swing speed is faster. When the first blade 110 on the left side of the centerline of the disc body 100, with a larger angle to the centerline, strikes the material below the discharge port, the angle between the direction the material flies out and the horizontal direction is larger, so the material can fly closer. When the swivel disc 010 swings to the left, its swing speed is slower. When the first blade 110 on the right side of the centerline of the disc body 100, with a smaller angle to the centerline, strikes the material below the discharge port, the angle between the direction the material flies out and the horizontal direction is smaller, so the material flies farther. In this way, the reciprocating swivel disc 010 can more evenly distribute the material to both sides of the swivel disc 010.

[0092] It should be noted that the angle between the first blade 110 and the centerline specifically refers to the angle between the first blade 110 and the centerline when the first blade 110 and the centerline are projected onto the set plane a.

[0093] Furthermore, at least a portion of the first blades 110 distributed on one side of the center line form an angle with the center line that is greater than the angle with the center line of the first blades 110 symmetrically distributed on the other side of the center line; that is, multiple first blades 110 on the left and right sides of the center line of the disk body 100 are symmetrically distributed along the center line, wherein the angles between some of the left and right symmetrical first blades 110 are different, and the angle between some of the first blades 110 distributed on the left side and the center line is greater than the angle between the first blades 110 symmetrically distributed on the right side and the center line. In this way, when the swivel disc 010 swings to the right, its swing speed is faster. The first blade 110, which is located on the left side of the center line of the disc body 100 and has a larger angle with the center line, strikes the material below the discharge port, causing the material to fly closer. When the swivel disc 010 swings to the left, its swing speed is slower. The first blade 110, which is located on the right side of the center line of the disc body 100 and has a smaller angle with the center line, strikes the material below the discharge port, causing the material to fly farther. This ensures the uniformity of material spreading by the swivel disc 010.

[0094] Alternatively, please refer to Figure 4 The two first blades 110 located on either side of the center line and close to the center line have the same angle with the center line; the remaining first blades 110 located on one side of the center line have a greater angle with the center line than the remaining first blades 110 located on the other side of the center line. That is, the angle between the first blade 110 located to the left of the center line and close to the center line is equal to the angle between the first blade 110 located to the right of the center line and close to the center line. The other first blades 110 located to the left of the center line of the disk body 100 have the same angle with the center line. The angle between the first blade 110 and the center line is greater than the angle between the first blade 110 symmetrically distributed to the right of the center line of the disk 100 and the center line; or, the angle between the first blade 110 located to the left of the center line and close to the center line of the disk 100 is smaller than the angle between the first blade 110 located to the right of the center line and close to the center line of the disk 100, while the angle between the other first blades 110 located to the left of the center line of the disk 100 and the center line is greater than the angle between the first blades 110 symmetrically distributed to the right of the center line of the disk 100 and the center line. This arrangement ensures that the two first blades 110 close to the center line can push the material to a position close to the second axis L2, thereby ensuring that the material is not only pushed to the left and right sides of the throwing disk 010 and to a position far from the throwing disk 010, but also to a position close to the throwing disk 010, thus ensuring the uniformity of material distribution.

[0095] Alternatively, please refer to Figure 4 The spreading disc 010 includes at least two second blades 120, with second blades 120 distributed on both sides of the center line. A first blade 110 located on either side of the center line is closer to the center line than any second blade 120 located on the same side. Specifically, all first blades 110 located to the left of the center line are closer to the center line than any second blade 120 on the left, and all first blades 110 located to the right of the center line are closer to the center line than any second blade 120 on the right. This arrangement allows the material to be spread further using the distal ends of the first blades 110, increasing the spreading width of the spreading disc 010, and also allows the second blades 120 to spread the material to positions relatively close to the spreading disc 010, thereby ensuring uniform material spreading.

[0096] Alternatively, please refer to Figure 4 Multiple second blades 120 are distributed on both sides of the center line. Specifically, the multiple second blades 120 are all connected to the dialing unit 160 and are distributed at intervals along the extension direction of the dialing unit 160. The angle between at least a portion of the second blades 120 distributed on one side of the center line and the center line is greater than the angle between at least a portion of the second blades 120 distributed on the other side of the center line and the center line. Specifically, the first arc-shaped segment 161 and the second arc-shaped segment 162 of the dialing unit 160 are both connected to multiple second blades 120. The angle between at least a portion of the multiple second blades 120 disposed on the first arc-shaped segment 161 and the center line is greater than the angle between at least a portion of the multiple second blades 120 disposed on the second arc-shaped segment 162 and the center line, that is, the angle between at least a portion of the second blades 120 distributed on the left side of the center line and the center line is greater than the angle between at least a portion of the second blades 120 distributed on the right side of the center line and the center line. When the swivel disc 010 swings to the right, its swing speed is faster. When the second blade 120, located to the left of the center line of the disc body 100 and with a larger angle to the center line, strikes the material below the discharge port, 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 swivel disc 010 swings to the left, its swing speed is slower. When the second blade 120, located to the right of the center line of the disc body 100 and with a smaller angle to the center line, strikes the material below the discharge port, 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 swivel disc 010 distributes the material more evenly to both sides of the swivel disc 010.

[0097] It should be noted that the angle between the second blade 120 and the centerline specifically refers to the angle between the second blade 120 and the centerline when the second blade 120 and the centerline are projected onto the set plane a.

[0098] Furthermore, at least a portion of the second blades 120 distributed on one side of the center line form an angle with the center line that is greater than the angle with the center line of the second blades 120 symmetrically distributed on the other side of the center line; that is, multiple second blades 120 on the left and right sides of the center line of the disk body 100 are symmetrically distributed along the center line, wherein the angles between some of the symmetrical second blades 120 are different, and the angle between some of the second blades 120 distributed on the left side and the center line is greater than the angle between the second blades 120 symmetrically distributed on the right side and the center line. In this way, when the swivel disc 010 swings to the right, its swing speed is faster, and the second blade 120, which is located on the left side of the center line of the disc body 100 and has a larger angle with the center line, strikes the material below the discharge port, causing the material to fly closer. When the swivel disc 010 swings to the left, its swing speed is slower, and the second blade 120, which is located on the right side of the center line of the disc body 100 and has a smaller angle with the center line, strikes the material below the discharge port, causing the material to fly farther. This ensures the uniformity of material spreading by the reciprocating swivel disc 010.

[0099] Alternatively, please refer to Figure 4 Multiple first blades 110 and multiple second blades 120 are distributed on both sides of the center line. On one side of the center line, the angle between the first blade 110 closest to the center line and the center line is smaller than the angle between the second blade 110 closest to the center line and the center line. The angle between the second blade 110 closest to the center line and the center line is at least greater than the angle between one of the second blades 120 on the same side and the center line. The angle between the first blade 120 closest to the center line and the center line is greater than the angle between the second blade 120 closest to the center line and the center line. This configuration ensures that during the reciprocating oscillation of the spinning disc 010, the blades with larger angles push the material closer and the blades with smaller angles push the material further away, ensuring uniform spreading.

[0100] Alternatively, please refer to Figure 4 On the left or right side of the centerline, there is a pair of adjacent first blades 110 and second blades 120, and the angle between the first blade 110 and the centerline is greater than or equal to the angle between the adjacent second blade 120 and the centerline.

[0101] Alternatively, please refer to Figure 4On one side of the center line, the second blade 120 furthest from the center line has the smallest angle with the center line, while the first blade 110 closest to the center line has the second smallest angle with the center line. Similarly, on the right side of the center line, among the multiple second blades 120 positioned on the right, the second blade 120 furthest from the center line has the smallest angle with the center line, and among the multiple first blades 110 positioned on the right, the first blade 110 closest to the center line has the second smallest angle with the center line. Likewise, on the left side of the center line, among the multiple second blades 120 positioned on the left, the second blade 120 furthest from the center line has the smallest angle with the center line, and among the multiple first blades 110 positioned on the left, the first blade 110 closest to the center line has the second smallest angle with the center line. This arrangement ensures that during the reciprocating oscillation of the spinning disc 010, the blades with larger angles push the material closer, while the blades with smaller angles push the material further away. The alternating arrangement of large and small angle blades ensures that the material is alternately pushed to near and far, guaranteeing uniform spreading.

[0102] Optionally, on one side of the centerline, the intersection points of the extension lines of the orthographic projections of each first blade 110 and each second blade 120 onto the length extension direction of the set plane a with the centerline do not coincide. That is, the intersection points of the extension lines of the orthographic projections of each first blade 110 and each second blade 120 onto the length extension direction of the set plane a with the centerline are distributed sequentially at intervals along the length extension direction of the centerline. Of course, in other embodiments, the intersection points of the extension lines of the orthographic projections of each first blade 110 and each second blade 120 onto the length extension direction of the set plane a with the centerline coincide. For example, the intersection points of the extension lines of the orthographic projections of each first blade 110 and each second blade 120 onto the length extension direction of the set plane a with the centerline all coincide with the swing center of the disk body 100.

[0103] For example, the swivel disc 010 of this embodiment further includes four second blades 120, with two second blades 120 distributed on each side of the center line, that is, the first arc segment 161 and the second arc segment 162 are each connected to two second blades 120, and the first arc segment 161 and the second arc segment 162 are each connected to two flanges 130; on either side of the center line, each first blade 110 is closer to the center line than any second blade 120. On the first arc segment 161, that is, as shown... Figure 4 To the left of the centerline, the angle between the first blade 110 closest to the centerline and the centerline can be considered the first angle; the angle between the second blade 110 closest to the centerline and the centerline can be considered the second angle; the angle between the second blade 120 closest to the centerline and the centerline can be considered the third angle; and the angle between the second blade 120 furthest from the centerline and the centerline can be considered the fourth angle. The order is: second angle > third angle > first angle > fourth angle. On the second arc segment 162, i.e.... Figure 4To the right of the center line, the angle between the first blade 110 closest to the center line and the center line can be the fifth angle, the angle between the second blade 110 closest to the center line and the center line can be the sixth angle, the angle between the second blade 120 closest to the center line and the center line can be the seventh angle, and the angle between the second blade 120 furthest from the center line and the center line can be the eighth angle, with the sixth angle > the seventh angle > the fifth angle > the eighth angle.

[0104] Of course, in another embodiment, the number of second blades 120 can be one, two, three, five, six, etc., and no specific limitation is made here.

[0105] The unmanned equipment in this embodiment can be used to spread granular materials such as seeds and fertilizers. When in use, the material is stored in the hopper and allowed to enter the shell. The material is then output from the outlet through the auger and spread out by the reciprocating oscillating disc 010.

[0106] In summary, the spreading mechanism of the present invention can increase the spreading range, which is beneficial to improving spreading efficiency and reducing the number of reciprocating movements of unmanned equipment.

[0107] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
