Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0044] Please refer to Figure 1 This embodiment provides an unmanned device, which may refer to drones, unmanned vehicles, etc., without specific limitations.
[0045] 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.
[0046] The spreading device includes a material storage mechanism and a spreading mechanism 010 (e.g. Figure 1 As shown, the spreading mechanism 010 is located in the storage mechanism, which is used to store materials and to transport the materials to the spreading mechanism 010 for spreading.
[0047] Optionally, the storage mechanism includes a hopper for storing materials; the hopper has a discharge port, through which the materials can fall under their own weight and move to the spreading mechanism 010 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 and a roller assembly.
[0048] Alternatively, please refer to Figure 1 and Figure 2The spreading mechanism 010 includes a conveying assembly (not shown), a drive assembly 200, and a slinger 300. The drive assembly 200 is disposed on the conveying assembly. The conveying assembly is provided with a discharge port 102, which is used to output materials from the discharge port 102. The drive assembly 200 is in transmission cooperation with the slinger 300, and is used to drive the slinger 300 to rotate around the first axis L1. Specifically, the conveying assembly includes a housing 100 and an auger. The housing 100 is connected to the material box. An inlet 101 is provided on the upper side of the housing 100. The inlet 101 is opposite to and communicates with the discharge port. The end of the body 100 is provided with a discharge port 102; the auger is rotatably disposed inside the housing 100 for conveying the material entering the housing 100 toward the discharge port 102 and causing the material to fall out from the discharge port 102; the drive assembly 200 is disposed in the housing 100 and is connected to the slinger 300 for driving the slinger 300 to rotate, and the slinger 300 is distributed relative to the discharge port 102; when the slinger 300 rotates around the first axis L1 under the drive of the drive assembly 200, the slinger 300 can push the material falling out of the discharge port 102 out.
[0049] Furthermore, the housing 100 is equipped with a motor that is connected to the auger drive.
[0050] Please refer to Figure 3 In this embodiment, the swivel disc 300 includes a disc body 400 and blades 500. The disc body 400 includes a connecting part 410 and a dialing part 420. The connecting part 410 is connected to the drive assembly 200 to drive the swivel disc 300 to rotate around the first axis L1 under the drive of the drive assembly 200. The blades 500 are disposed on the dialing part 420 and are used to dial the material. The dialing part 420 is arc-shaped and surrounds the connecting part 410 at a specific angle, which is less than 360°. This configuration provides higher structural efficiency for reciprocating oscillations with changing directions. Since only a portion of the blades 500 can dial the material during reciprocating oscillations, the dialing part 420 does not need to form a complete circle. This allows for a reduction in the volume of the disc body 400, thereby reducing the weight of the entire swivel disc 300, lessening the load on the drive assembly 200, reducing the cost of manufacturing the swivel disc 300, and improving structural efficiency.
[0051] Furthermore, specific angles are configured to be less than 180°, such as 179°, 175°, 165°, 160°, etc., which can be determined according to the set swing amplitude. This setting can significantly reduce the size and weight of the slinger 300, thereby reducing the load on the drive assembly 200 and lowering the manufacturing cost of the slinger 300, while ensuring reliable material feeding.
[0052] Of course, in other embodiments, the specific angle may be greater than or equal to 180°, such as 180°, 200°, 240°, etc., which are not specifically limited here.
[0053] In one embodiment, the connecting part 410 includes a rotation center, and the specific angle around the dialing part 420 surrounding the connecting part 410 can refer to the angle formed between the two ends of the dialing part 420 and the rotation center respectively.
[0054] Furthermore, 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. Blades 500 are distributed on the first side, and the drive 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. This arrangement enables the material output from the discharge port 102 to be reliably driven by the blades 500 connected to the first side of the disc body 400.
[0055] In some embodiments, the drive assembly 200 is configured to drive the disc 400 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 300, that is, the material spread distribution is uneven.
[0056] Please refer to Figure 2 In this embodiment, the drive component 200 is configured to drive the disc body 400 to reciprocate 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 problem of uneven spreading caused by the blades 500 rotating above the discharge port 102 as the disc body 400 rotates and failing to pick up the material, resulting in the material falling directly without being picked up. On the other hand, the reciprocating blades 500 make the material pick up more evenly, that is, the reciprocating disc 300 can evenly pick up the material to the left and right sides of the vertical center line of the disc 300, achieving symmetrical spreading and uniformity of material within the spreading area.
[0057] Please refer to Figure 4 and Figure 5The drive assembly 200 includes a motor 210 and a crank assembly 220, with the motor 210 being connected to the disc body 400 via 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 in the housing 100 and is drivenly connected to the output shaft of the motor 210. The protrusion 222 is connected to the turntable 221 and is distributed at intervals from the rotation center of the turntable 221. The protrusion 222 is slidably inserted into the groove 224 of the track 223. The end of the track 223 is connected to the disc body 400 and is pivotally connected to the housing 100. When the motor 210 drives the turntable 221 to rotate in one direction, the protrusion 222 rotates synchronously with the turntable 221. The protrusion 222 reciprocates in the groove 224 of the track 223 and abuts against the groove wall of the groove 224, thereby driving the track 223 to swing back and forth around its end pivotally connected to the housing 100, thereby driving the disc body 400 to swing back and forth. Alternatively, for example, in some 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 in the housing 100 and is 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, and 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 in the housing 100 and is connected to the swivel disc 300. When the output shaft of the motor 210 rotates in one direction, it drives the first connecting rod 225 to rotate, and through the first connecting rod 225, it drives the second connecting rod 226 to swing, thereby using the second connecting rod 226 to drive the third connecting rod 227 and the swivel disc 300 to swing back and forth.
[0058] Please refer to Figure 3 In this embodiment, the disc body 400 is provided with a hollow area 401, which is used to allow material to pass through. In this way, a portion of the material conveyed from the discharge port 102 can fall directly through the hollow area 401, thereby preventing the material from directly impacting the swivel disc 300 under high flow conditions, causing the swivel disc 300 to bear excessive load and triggering the overcurrent protection of the motor 210 that drives the swivel disc 300. Moreover, due to the reciprocating swivel characteristics of the swivel disc 300, the blades 500 can scatter the material to the left and right sides of the vertical center line of the disc body 400, resulting in less material being spread in the middle. The hollow area 401 of the disc body 400 allows some material to pass directly without passing through the blades 500, thus making the overall spreading effect more uniform and better. Furthermore, it can further reduce the overall weight of the swivel disc 300 and reduce the load on the motor 210.
[0059] Furthermore, the perforated area 401 extends through both the first and second sides, allowing material to move from the first side to the second side and fall freely thereafter. This arrangement prevents the freely falling material from being knocked away by the blades 500, thereby ensuring that the center of the dispensing disc 300 contains freely falling material and ensuring the uniformity of the material distribution.
[0060] Of course, in other embodiments, the disk body 400 may not have a cutout area 401.
[0061] Furthermore, the disc 400 is configured to reciprocate around a first axis L1 in a vertical plane, and the blades 500 can move below the discharge port 102 as the disc 400 oscillates. This configuration ensures that the blades 500 can reliably dispense material, thereby ensuring the reliability of material dispensing.
[0062] Please refer to Figure 3 In this embodiment, the connecting part 410 is provided with a hollow area 401; this arrangement can avoid interference between the material that needs to fall freely from the hollow area 401 and the material that needs to be pushed by the blade 500, thereby ensuring the reliability and uniformity of the spreading.
[0063] Of course, in other embodiments, the cutout area 401 may extend to the dialing part 420; in this way, the lowest point of the cutout area 401 can be lowered, so that the material can pass through the cutout area 401 more easily.
[0064] Furthermore, the connecting part 410 includes a mounting part 411 and at least two connecting members 412. The first end of the connecting member 412 is connected to the dialing part 420, and the second ends of the at least two connecting members 412 are both connected to the mounting part 411. The mounting part 411 is connected to the drive assembly 200 in a transmission manner. The at least two connecting members 412 are distributed at intervals around the first axis L1 to form a hollow area 401. With this arrangement, the size of the hollow area 401 and the structural strength of the disc body 400 can be adjusted by adjusting the size and number of the connecting members 412, thereby improving flexibility.
[0065] In this embodiment, the connecting part 410 includes three connectors 412, which are distributed at intervals around the first axis L1 to form two hollow areas 401. This arrangement not only increases the range through which materials can pass through the disc body 400 to ensure the smooth drop of materials in the middle of the throwing disc 300, but also improves the structural strength of the disc body 400.
[0066] Of course, in other embodiments, the number of connectors 412 can be two, four, etc., and no specific limitation is made here.
[0067] The connection method between connector 412, mounting part 411 and dialing unit 420, and the connection method between blade 500 and dialing unit 420 can be selected as needed, such as integral molding, welding, etc., and no specific limitation is made here.
[0068] Please refer to Figure 3 In this embodiment, the center of the dialing unit 420 coincides with the first axis L1, and the swivel disc 300 includes multiple blades 500, all of which are connected to the dialing unit 420 and are distributed sequentially at intervals along the length extension direction of the dialing unit 420, so that the multiple blades 500 are distributed sequentially at intervals along a preset arc. This arrangement allows for more reliable material dispensing using the multiple blades 500 when the dialing unit 420 reciprocates around the first axis L1, ensuring uniform material distribution.
[0069] Further, the drive assembly 200 is used to drive the disk 400 to reciprocate around the first axis L1 on both sides of the second axis L2, the second axis L2 being perpendicular to the first axis L1; wherein, when the disk 400 is stationary, the centerline of the disk 400 coincides with the second axis L2; multiple blades 500 are distributed on both sides of the centerline, and the angle between at least a portion of the blades 500 distributed on one side of the centerline and the centerline is greater than the angle between at least a portion of the blades 500 distributed on the other side of the centerline and the centerline; specifically The dialing unit 420 includes a first arc-shaped segment 421 and a second arc-shaped segment 422 connected to each other, and the connection point of the first arc-shaped segment 421 and the second arc-shaped segment 422 is the centerline of the disc body 400; both the first arc-shaped segment 421 and the second arc-shaped segment 422 are connected to a plurality of blades 500; wherein, at least a portion of the blades 500 connected to the first arc-shaped segment 421 forms an angle with the centerline that is greater than the angle with the centerline that is at least a portion of the blades 500 connected to the second arc-shaped segment 422; wherein, the first arc-shaped segment 421 is... Figure 6 The middle section is distributed on the left side, and the second arc segment 422 is... Figure 6 The middle section is distributed on the right side, that is, distributed in Figure 6 At least one of the multiple blades 500 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 6 The angle between one of the multiple blades on the right side of the center and the centerline.
[0070] Because the swivel 300 is driven by the crank assembly 220 to oscillate reciprocally (as... Figure 6 The reciprocating oscillation of the crank 300 is a simple harmonic motion, and due to the quick-return characteristic of the crank assembly 220, the crank 300 will have different speeds during its left and right reciprocating oscillations. For example, Figure 6 As shown, the speed at which the 300-speed swivel to the left is slightly slower than its speed to the right, and the distribution will be... Figure 6At least one of the multiple blades 500 on the left side is configured to form an angle with the centerline that is greater than that distributed on the left side. Figure 6 One of the multiple blades 500 on the right side of the disc 300 forms an angle with the centerline. When the disc 300 swings to the right, its swing speed is faster. When the blades 500 on the left side of the centerline of the disc 400, which have a larger angle with the centerline, strike the material below the discharge port 102, 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 disc 300 swings to the left, its swing speed is slower. When the blades 500 on the right side of the centerline of the disc 400, which have a smaller angle with the centerline, strike the material below the discharge port 102, 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 swinging disc 300 will distribute the material more evenly to both sides of the disc 300.
[0071] Furthermore, the angle between the width extension direction of at least a portion of the blades 500 distributed on one side of the centerline and the centerline is greater than the angle between the width extension direction of at least a portion of the blades 500 distributed on the other side of the centerline and the centerline. This arrangement ensures that the reciprocating disc 300, under the action of the crank assembly 220, can achieve uniform spraying on both sides by adjusting the angle between the width extension directions of the blades 500 on both sides of the centerline.
[0072] It should be noted that the length extension direction of the blade 500 refers to the direction perpendicular to the surface of the disk 400, and the width extension direction of the blade 500 can refer to the extension direction of the blade 500 projected onto the surface of the disk 400.
[0073] Optionally, at least some of the blades 500 distributed on one side of the centerline form an angle with the centerline that is greater than the angle with the centerline of the blades 500 symmetrically distributed on the other side of the centerline; that is, multiple blades 500 on the left and right sides of the centerline of the disk 400 are symmetrically distributed along the centerline, wherein the angles between some of the symmetrical blades 500 on the left and right sides are different, and the angle between some of the blades 500 on the left side and the centerline is greater than the angle between the blades 500 symmetrically distributed on the right side and the centerline. In this way, when the swivel disc 300 swings to the right, its swing speed is faster, and the blades 500, which are distributed on the left side of the center line of the disc body 400 and have a larger angle with the center line, strike the material below the discharge port 102, causing the material to fly closer. When the swivel disc 300 swings to the left, its swing speed is slower, and the blades 500, which are distributed on the right side of the center line of the disc body 400 and have a smaller angle with the center line, strike the material below the discharge port 102, causing the material to fly farther. This ensures the uniformity of material spreading by the swivel disc 300.
[0074] Optionally, the two blades 500 located on both sides of the center line and close to the center line have the same angle with the center line; the remaining blades 500 located on one side of the center line have an angle with the center line that is greater than the remaining blades 500 located on the other side of the center line. That is, the blade 500 located to the left of the center line of the disk 400 and close to the center line has an angle with the center line that is equal to the blade 500 located to the right of the center line of the disk 400 and close to the center line. The other blades 500 located to the left of the center line of the disk 400 have an angle with the center line that is greater than the blades 500 symmetrically distributed to the right of the center line of the disk 400. This configuration allows both blades 500 near the center line to push the material to a position close to the second axis L2, thus ensuring that the material is not only pushed to the left and right sides of the throwing disc 300 and to a position far away from the throwing disc 300, but also pushed to a position close to the throwing disc 300, ensuring the uniformity of material distribution.
[0075] Optionally, on one side of the center line, starting from the second blade 500 closest to the center line and moving 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, starting from the second blade 500 closest to the center line and moving away from the center line, the angle between each blade 500 and the center line gradually decreases. Similarly, on the left side of the center line, starting from the second blade 500 closest to the center line and moving away from the center line, the angle between each blade 500 and the center line gradually decreases. This arrangement ensures that during the reciprocating oscillation of the dispensing disc 300, the blades 500 with larger angles push the material closer and the blades 500 with smaller angles push the material further away, ensuring uniform dispensing.
[0076] Optionally, on one side of the center line, the blade 500 furthest from the center line has the smallest angle with the center line, and the blade 500 closest to the center line has the second smallest angle with the center line. That is, on the right side of the center line, among the multiple blades 500 positioned on the right, the blade 500 furthest from the center line has the smallest angle with the center line, and the blade 500 closest to the center line has the second smallest angle with the center line. Similarly, on the left side of the center line, among the multiple blades 500 positioned on the left, the blade 500 furthest from the center line has the smallest angle with the center line, and the blade 500 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 300, the blades 500 with larger angles push the material closer, and the blades 500 with smaller angles push the material further away. By alternating the arrangement of the blades 500 with larger and smaller angles, the material is alternately pushed to both near and far, ensuring uniform spreading.
[0077] Optionally, on one side of the center line, the intersection points of the extension lines of the width extension direction of each blade 500 with the center line do not coincide, that is, the intersection points of the extension lines of the width extension direction of each blade 500 with the center line are distributed sequentially at intervals 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 direction of each blade 500 with the center line coincide, for example: the intersection points of the extension lines of the width extension direction of each blade 500 with the center line all coincide with the swing center of the disk body 400.
[0078] Please refer to Figure 6 In this embodiment, the plurality of 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. The first blade 501 and the second blade 502 are distributed to the left of the center line, and the first blade 501 is closer to the center line than the second blade 502. The third blade 503 and the fourth blade 504 are distributed to the right of the center line, and the third blade 503 is closer to the center line than the fourth blade 504. The angle between the first blade 501 and the center line is equal to the angle between the third blade 503 and the center line, and the angles between the first blade 501 and the center line and the third blade 503 and the center line are both 23°. The angle between the second blade 502 and the center line is greater than the angle between the fourth blade 504 and the center line. The angle between the second blade 502 and the center line is 47.5°, and the angle between the fourth blade 504 and the center line is 33°.
[0079] Of course, in other embodiments, the angle between the first blade 501 and the centerline, and the angle between the third blade 503 and the centerline are arbitrary values of 20°-25°, such as 20°, 21°, 22°, 24° or 25°; the angle between the second blade 502 and the centerline are arbitrary values of 45°-50°, such as 45°, 46°, 47°, 48°, 49°, 50°; and the angle between the fourth blade 504 and the centerline are arbitrary values of 30°-35°, such as 30°, 31°, 32°, 33°, 34°, 35°.
[0080] Furthermore, the plurality of blades 500 also includes 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. The angle between the fifth blade 505 and the centerline is greater than the angle between the sixth blade 506 and the centerline. The angle between the fifth blade 505 and the centerline is greater than the angle between the second blade 502 and the centerline, and the angle between the second blade 502 and the centerline is greater than the angle between the first blade 501 and the centerline. The angle between the sixth blade 506 and the centerline is greater than the angle between the fourth blade 504 and the centerline, and the angle between the fourth blade 504 and the centerline is greater than the angle between the third blade 503 and the centerline. The angle between the fifth blade 505 and the centerline is 54.5°, and the angle between the sixth blade 506 and the centerline is 46.5°.
[0081] Of course, in other embodiments, the angle between the fifth blade 505 and the centerline can be any value between 53° and 57°, such as 53°, 54°, 55°, 56°, 57°, etc.; the angle between the sixth blade 506 and the centerline can be any value between 44° and 48°, such as 44°, 45°, 46°, 47°, 48°, etc.
[0082] Furthermore, the plurality of blades 500 also includes 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 centerline is greater than the angle between the eighth blade 508 and the centerline. The angle between the seventh blade 507 and the centerline is less than the angle between the first blade 501 and the centerline, and the angle between the first blade 501 and the centerline is less than the angle between the second blade 502 and the centerline. The angle between the eighth blade 508 and the centerline is less than the angle between the third blade 503 and the centerline, and the angle between the third blade 503 and the centerline is less than the angle between the fourth blade 504 and the centerline. Among these, the angle between the seventh blade 507 and the centerline is 6°, and the angle between the eighth blade 508 and the centerline is 5.5°.
[0083] Of course, in other embodiments, the angle between the seventh blade 507 and the centerline can be any value between 5° and 8°, such as 5°, 6°, 7°, 8°, etc., and the angle between the eighth blade 508 and the centerline can be any value between 4° and 6°, such as 4°, 5°, 6°, etc.
[0084] Please refer to Figure 6The blade 500 includes two opposing striking surfaces for striking materials, namely a first striking surface and a second striking surface. When the disc 400 oscillates around the first axis L1 along a first direction N1, the first striking surface strikes materials; when the disc 400 oscillates around the first axis L1 along a second direction N2, the second striking surface strikes materials. The first direction N1 and the second direction N2 are opposite; specifically, the first direction N1 can point to the left, and the second direction N2 can point to the right. In this embodiment, both the first striking surface and the second striking surface are planar and parallel to each other.
[0085] Please refer to Figure 7 In another embodiment, the width extension direction of the first dialing surface is at an acute angle to the width extension direction of the second dialing surface, and one end of both the first and second dialing surfaces are aligned with the outer edge of the dialing part 420. The other ends of the first and second dialing surfaces extend towards the swing center of the disc body 400, and the included angle between the first and second dialing surfaces gradually increases from the end near the outer edge of the dialing part 420 to the end near the swing center of the disc body 400. This allows for flexible setting of the included angle between the two dialing surfaces of the same blade 500, achieving a more uniform material dialing effect.
[0086] Furthermore, the angle between the line connecting the swing centers of the blade 500 and the disc 400 and the first dialing surface is the first included angle; the angle between the line connecting the swing centers of the blade 500 and the disc 400 and the second dialing surface is the second included angle; along the first direction N1, the angles of the first included angles of the plurality of blades 500 gradually decrease, and along the second direction N2, the angles of the second included angles of the plurality of blades 500 gradually decrease, for example: the first included angle a1 of the seventh blade 507 < the first included angle b1 of the second blade 502 < the first included angle c1 of the fifth blade 505 < the first included angle c1 of the first blade 501. The first included angle d1 < the first included angle e1 of the third blade 503 < the first included angle f1 of the sixth blade 506 < the first included angle g1 of the fourth blade 504 < the first included angle h1 of the eighth blade 508, and the second included angle a2 of the eighth blade 508 < the second included angle b2 of the fourth blade 504 < the second included angle c2 of the sixth blade 506 < the second included angle d2 of the third blade 503 < the second included angle e2 of the first blade 501 < the second included angle f2 of the fifth blade 505 < the second included angle g2 of the second blade 502 < the second included angle h2 of the seventh blade 507. In this way, when the swivel disc 300 swings to the left, the left-side striking surface of the blade 500 becomes the first striking surface, and the left-side striking surface of each blade 500 contacts the material output from the discharge port 102. The blade 500 with the smaller first angle contacts the material first, striking the material to a distance, while the blade 500 with the larger first angle contacts the material later, striking the material to a closer distance. This allows multiple blades 500 to disperse the material from a distance to a closer distance, increasing the uniformity of spreading. The same applies when the swivel disc 300 swings to the right.
[0087] It should be noted that the line connecting the swing center of the blade 500 and the disc 400 can refer to the line connecting the middle of the end of the blade 500 near the dialing part 420 and the swing center of the disc 400.
[0088] Please refer to Figure 8 and Figure 9 In another embodiment, at least one of the striking surfaces of at least a portion of the blades 500 is an arc-shaped surface, that is, at least one of the first striking surface and the second striking surface of at least a portion of the blades 500 is an arc-shaped surface. When the blades 500 rotate with the disc body 400 to a specific angle, the arc-shaped striking surface has more different contact angles with the material, so as to strike the material at multiple angles and improve the uniformity of striking.
[0089] Optionally, at least one striking surface of all blades 500 is an arc-shaped surface. For example, the first striking surface of all blades 500 is an arc-shaped surface, or the second striking surface of all blades 500 is an arc-shaped surface, or the first striking surface of some blades 500 is an arc-shaped surface and the second striking surface of other blades 500 is an arc-shaped surface. This configuration allows the material to be struck at multiple angles using the arc-shaped striking surfaces, improving the uniformity of material distribution.
[0090] Alternatively, please refer to Figure 8 Both striking surfaces of all blades 500 are curved, meaning both the first and second striking surfaces of all blades 500 are curved. This allows any striking surface of any blade 500 to have more diverse contact angles with the material, enabling the material to be struck from multiple angles. This improves the problem of material concentration in certain areas after spreading, further enhancing the uniformity of material distribution.
[0091] Alternatively, please refer to Figure 9 In the plurality of blades 500 connected to the first arc-shaped segment 421, at least one blade 500 near the centerline has at least one arc-shaped dialing surface, while at least one blade 500 away from the centerline has two flat dialing surfaces. Similarly, in the plurality of blades 500 connected to the second arc-shaped segment 422, at least one blade 500 near the centerline has at least one arc-shaped dialing surface, while at least one blade 500 away from the centerline has two flat dialing surfaces. This arrangement ensures that the blades 500 located approximately in the middle of the disc 400 have at least one arc-shaped dialing surface. When the middle of the disc 400 sweeps across the concentrated material drop area in the middle of the discharge port 102 during reciprocating oscillation, the blades 500 with arc-shaped dialing surfaces can effectively disperse the densely falling material, improving the uniformity of spreading.
[0092] Furthermore, among the multiple blades 500 connected to the first arc-shaped segment 421, at least one of the blades 500 closest to the centerline and the second blade 500 closest to the centerline has an arc-shaped dialing surface, while the two dialing surfaces of the remaining blades 500 connected to the first arc-shaped segment 421 are planar. Similarly, among the multiple blades 500 connected to the second arc-shaped segment 422, at least one of the blades 500 closest to the centerline and the second blade 500 closest to the centerline has an arc-shaped dialing surface, while the two dialing surfaces of the remaining blades 500 connected to the second arc-shaped segment 422 are planar. This configuration allows for more reliable dispersion of material in the concentrated material discharge area of the discharge port 102.
[0093] Alternatively, please refer to Figure 9In the first arc-shaped segment 421, at least one blade 500 near the centerline has two arc-shaped dispensing surfaces; similarly, in the second arc-shaped segment 422, at least one blade 500 near the centerline has two arc-shaped dispensing surfaces. This configuration ensures that the two dispensing surfaces of the blades 500 located approximately in the center of the disc 400 are arc-shaped. When the center of the disc 400 swings in either the first direction N1 or the second direction N2, and sweeps across the concentrated material drop area in the center of the discharge port 102, the arc-shaped dispensing surfaces effectively disperse the densely falling material, improving the uniformity of the spreading.
[0094] Furthermore, among the multiple blades 500 connected to the first arc-shaped segment 421, the blade 500 closest to the centerline and the second blade 500 closest to the centerline both have arc-shaped dialing surfaces, while the remaining blades 500 connected to the first arc-shaped segment 421 both have flat dialing surfaces. Similarly, among the multiple blades 500 connected to the second arc-shaped segment 422, the blade 500 closest to the centerline and the second blade 500 closest to the centerline both have arc-shaped dialing surfaces, while the remaining blades 500 connected to the second arc-shaped segment 422 both have flat dialing surfaces. This configuration ensures that material in the concentrated material drop area can be reliably dispersed even when the disc 400 swings in any direction. For example, the seventh blade 507, the second blade 502, the fourth blade 504, and the eighth blade 508 both have flat dialing surfaces, while the fifth blade 505, the first blade 501, the third blade 503, and the sixth blade 506 both have arc-shaped dialing surfaces.
[0095] It should be noted that both the spreading device and the spreading mechanism 010 can be independently installed on equipment such as tractors for use, and no specific limitations are made here.
[0096] 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 housing 100. The material is then output from the discharge port 102 by an auger and then spread out by the reciprocating oscillating disc 300.
[0097] In summary, the spreading mechanism 010 of the present invention has higher structural efficiency when the spreading disc 300 is used for reciprocating oscillation in different directions. Since only a portion of the blades 500 of the spreading disc 300 can reach the material during reciprocating oscillation, the spreading part 420 does not need to form a complete circle. This reduces the volume of the disc body 400 and the weight of the entire spreading disc 300, which helps to reduce the load on the drive assembly 200 that drives the spreading disc 300, and also reduces the cost of manufacturing the spreading disc 300, thereby improving structural efficiency.
[0098] The above description is merely a preferred embodiment of the present invention and is not intended to limit the 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.
