Description

Technical Field

[0001] This invention relates to the field of unmanned equipment technology, and more specifically, to a dispersing device, system, and unmanned equipment. Background Technology

[0002] Unmanned equipment, such as drones or unmanned vehicles, is widely used in the field of plant protection technology, specifically for operations such as seed sowing and watering. Unmanned equipment used for seed sowing needs to be equipped with a sowing system. This system typically includes a hopper, a feeding device, and a sowing device. The hopper, connected to the sowing device via the feeding device, stores seeds and other materials. The feeding device transports the material from the hopper to the sowing device, which then sows the material. The sowing device includes a motor and a rotating disc connected to the motor's drive. The motor drives the rotating disc to oscillate back and forth, thus dispersing the material.

[0003] Existing seeding devices employ a swing-type swivel disc. The motor is connected to the disc via a crank-connecting rod mechanism. The motor only needs to rotate rapidly in one direction to drive the crank-connecting rod mechanism, converting the motor's circular motion into the reciprocating oscillation of the disc. However, this transmission method has a complex structure, faces numerous reliability challenges, and is costly. Summary of the Invention

[0004] This invention provides a novel oscillating spraying device with a spinning disc. The output shaft of a motor directly drives the spinning disc, and the reciprocating oscillation of the disc can be achieved by controlling the forward and reverse rotation of the motor's output shaft. However, using the forward and reverse rotation of the motor's output shaft to drive the spinning disc reciprocating oscillation requires the motor to constantly stop and accelerate in the opposite direction, resulting in extremely high power consumption and severe heat generation. This not only affects the battery's range of power supply to the motor but also easily burns out the motor. Therefore, an elastic element is also configured to use the elastic potential energy released by the elastic element to drive the spinning disc to oscillate in the opposite direction. However, there is a mutual antagonistic effect between the elastic elements, which reduces the conversion rate of the elastic potential energy of the elastic elements into the power of the spinning disc oscillation.

[0005] The seeding device provided by this invention can be used in the seeding system of unmanned equipment. This seeding device can not only reduce the power consumption of the motor and improve the problem of severe motor overheating, thereby helping to extend the battery life that provides power to the motor and effectively improve the problem of motor burnout, but also enable the elastic elements to cooperate with each other, improving the problem of reduced conversion rate of elastic potential energy of elastic elements into swinging power of the disc due to mutual resistance between multiple elastic elements.

[0024] In an optional embodiment, both the first elastic element and the second elastic element are disposed on a plane parallel to the swing plane of the swivel disc, and the elastic force provided by the first elastic element and the second elastic element is perpendicular to the output shaft axis of the motor.

[0025] In an optional embodiment, at least one of the first elastic element and the second elastic element includes a spring, and both ends of the spring are provided with connectors. The connectors are provided with helical grooves, and the connectors are fixed to the spring when the spring coil is screwed into the helical grooves.

[0026] In an alternative embodiment, the connector is provided with a flange, and the end of the spring abuts against the flange, which is used to prevent the spring from displacing axially.

[0034] The beneficial effects of the spreading device in this embodiment of the invention include: the spreading device provided in this embodiment of the invention includes a motor, a spinning disc, a first elastic element, and a second elastic element. The spinning disc is connected to the output shaft of the motor. When the spreading device is working, the output shaft of the motor drives the spinning disc to swing back and forth through forward and reverse rotation. The first end of the first elastic element and the first end of the second elastic element are respectively connected to a fixed position and rotatably connected to a solid at the fixed position. The second end of the first elastic element and the second end of the second elastic element are rotatably connected to the spinning disc or a swinging element that swings synchronously with the spinning disc. Both the first elastic element and the second elastic element can swing with the spinning disc. When the spinning disc is in the middle position, the length extension direction of both the first elastic element and the second elastic element points to the swing center of the spinning disc. When the spinning disc swings, the swing of the spinning disc is converted into axial deformation of the first elastic element and the second elastic element. When the first elastic element and the second elastic element release elastic potential energy, they can cooperate to drive the spinning disc to swing in the opposite direction. This configuration ensures that the first and second elastic elements, when releasing their elastic potential energy, are not in a state of mutual antagonism but rather cooperate with each other. This improves the problem of decreased energy conversion rate, specifically addressing the issue where the elastic potential energy released by one of the first and second elastic elements is simultaneously converted into the kinetic energy of the spinning disc, as well as the elastic potential energy of the other elastic element. This further mitigates the problem of reduced conversion of the elastic potential energy of the elastic elements into the kinetic energy of the spinning disc, ensuring that the motor reliably reduces power consumption. In other words, the centripetal installation of the elastic elements ensures that regardless of the direction the spinning disc swings, both the first and second elastic elements will extend simultaneously, and the elastic potential energy released by both elements can provide the torque needed to restore the spinning disc to its neutral position. This ensures that the first and second elastic elements cooperate with each other, rather than antagonize each other.

[0035] The seeding system of this invention includes all the beneficial effects of the aforementioned seeding device. For example, when the first elastic element and the second elastic element release elastic potential energy, they are not in a state of mutual antagonism, but rather cooperate with each other, which can improve the problem of decreased energy conversion rate.

[0036] The unmanned equipment in this embodiment of the invention includes all the beneficial effects of the aforementioned seeding system. For example, when the first elastic element and the second elastic element release elastic potential energy, they are not in a state of mutual antagonism, but rather cooperate with each other, which can improve the problem of decreased energy conversion rate.

[0059] Please refer to Figure 1 This embodiment provides an unmanned device, which may refer to a drone; of course, in other embodiments, the unmanned device may also refer to an unmanned vehicle, which is not specifically limited here.

[0060] Please refer to Figure 1 and Figure 2 The unmanned equipment includes an unmanned equipment body and a spreading system 110 installed on the unmanned equipment body. Specifically, the unmanned equipment body includes a load support 100, and the spreading system 110 is mounted on the load support 100. The spreading system 110 includes a material bin 111, a feeding device 112, and a spreading device 020. The material bin 111 is mounted on the load support 100 and connected to the spreading device 020 via the feeding device 112. The material bin 111 is used to store seeds and other materials. The feeding device 112 receives the materials output from the material bin 111 and transports the received materials to the spreading device 020, which then spreads the materials. The unmanned equipment body can refer to the unmanned aerial vehicle (UAV) itself.

[0061] It should be understood that the feeding device 112 is not a necessary structure. In other embodiments, the material bin 111 may not be connected to the spreading device 020 through the feeding device 112. That is, the material output from the material bin 111 does not need to be conveyed by the feeding device 112, but falls directly to the spreading device 020 for spreading.

[0062] Please refer to Figure 2 and Figure 3 The spreading device 020 of this embodiment includes a material cover 113, a motor 200, a support member 400, and a slinging disc 300. The material cover 113 is provided with a material inlet 114 and is connected between the feeding device 112 and the support member 400. The slinging disc 300 is located between the material cover 113 and the support member 400. The motor 200 is mounted on the support member 400, and the output shaft of the motor 200 is connected to the slinging disc 300 for driving the slinging disc 300 to swing back and forth around its own swing center on both sides of a set axis a. The swinging slinging disc 300 can spread the material that falls from the material inlet 114 into the space between the material cover 113 and the support member 400.

[0063] Furthermore, the support member 400 has a first side and a second side distributed opposite to each other. The first side is distributed opposite to the material cover 113. The slinger 300 is disposed on the first side, and the motor 200 is mounted on the second side. The output shaft of the motor 200 passes through the support member 400 and is connected to the slinger 300. This arrangement improves the integration of the spreading device 020.

[0064] The slinging disc 300 includes a disc body 310 and a paddle 320 connected to one side of the disc body 310. The output shaft of the motor 200 is connected to the disc body 310. The paddle 320 is distributed opposite to the material inlet 114 and swings with the disc body 310 to scatter the material.

[0065] Alternatively, in some embodiments, the motor 200 can be connected to the slewing disc 300 via a gearbox, which is not specifically limited here.

[0066] In related technologies, the output shaft of motor 200 is used to drive the swivel disc 300 to swing back and forth in both forward and reverse directions. This requires motor 200 to stop and accelerate in reverse frequently, resulting in extremely high power consumption and severe heat generation of motor 200. This not only affects the battery life that provides power to motor 200, but also easily burns out motor 200.

[0067] To improve the above problems, the spreading device 020 of this embodiment also includes an elastic element 510. The first end of the elastic element 510 is connected to a fixed position and rotatably connected to a solid at the fixed position. Specifically, the first end of the elastic element 510 is rotatably connected to the support member 400, that is, the solid at the fixed position refers to the support member 400. The second end of the elastic element 510 is rotatably connected to the swivel disc 300 or a swinging member that swings synchronously with the swivel disc 300. When the swivel disc 300 swings, the second end of the elastic element 510 swings with the swivel disc 300, and at the same time, the second end also rotates around the position to which it is connected. The first end of the elastic element 510 does not swing with the swivel disc 300, but it also rotates around the fixed position to which it is connected. Thus, the elastic element 510 can always maintain a straight shape during the swing of its second end. The swinging motion of the swivel disc 300 can be converted into the axial deformation of the elastic element 510, and the elastic element 510 can drive the swivel disc 300 to swing in the opposite direction when it releases elastic potential energy. This configuration allows the elastic deformation of the elastic element 510 to absorb and store energy, enabling the elastic element 510 to match the oscillation frequency of the swivel disc 300. This assists the swivel disc 300 in deceleration and reverse acceleration, reducing energy consumption during sudden stops and reverse acceleration of the motor 200. It also improves the problem of severe overheating of the motor 200, thereby extending the battery life that powers the motor 200 and effectively mitigating the problem of motor burnout. Furthermore, there is no need to set up additional motion conversion mechanisms to convert the circular motion of the swivel disc 300 into linear motion (e.g., slide rail assembly, gear rack, etc.). The variable length of the elastic element 510 allows for direct absorption and release of energy during the circular motion, avoiding unnecessary energy loss. More energy can be converted into the elastic potential energy of the elastic element 510, thus effectively reducing the energy consumption of the motor 200 driving the swivel disc 300 to reciprocate.

[0068] In related technologies, the spreading device 020 includes only one elastic element 510. To provide sufficient torque to the slinger 300, the elastic element 510 needs to be made very large. To improve the problem of needing to make the elastic element 510 very large, this embodiment uses the combined force of multiple elastic elements 510 (i.e., greater than or equal to two elastic elements 510) to provide torque. The following are several implementation methods, using two elastic elements 510 as an example: Implementation Method 1, please refer to... Figure 7 When the spinning disc 300 is in the neutral position, the two elastic elements 510 are at their natural length (i.e., neither stretched nor compressed). That is, when the spinning disc 300 is stationary, the two elastic elements 510 are in a state of neither stretching nor compression. When the spinning disc 300 swings, one elastic element 510 stretches, while the other elastic element 510 is compressed. For implementation method two, please refer to... Figure 8Both elastic elements 510 are in a stretched state when the spinning disc 300 is stationary or swinging, but to different degrees. When the spinning disc 300 is in the neutral position, the two elastic elements 510 are in equilibrium. When the spinning disc swings, the tension of one elastic element 510 increases, while the tension of the other elastic element 510 decreases. For implementation method three, please refer to... Figure 9 Both elastic elements 510 are in a compressed state when the spinning disc 300 is stationary or swinging, but the degree of compression is different. When the spinning disc 300 is in the middle position, the two elastic elements 510 are in equilibrium. When the spinning disc swings, the thrust of one elastic element 510 increases and the thrust of the other elastic element 510 decreases.

[0069] However, since the oscillating motion of the swivel disc 300 is an arc-shaped motion, the elastic element 510 in embodiments one and three will be subjected to a force different from the axial force provided by the swivel disc 300 when compressed. This force may cause the spring to bend (e.g., Figure 10 (As shown); To solve the above problems, a cylindrical retainer can be installed outside the elastic member 510 to confine the elastic member 510 within the cylindrical retainer and prevent the elastic member 510 from being bent. However, even so, the elastic member 510 will still be subjected to non-axial forces, and the elastic member 510 will still rub against the cylindrical wall of the retainer, which will have a significant impact on the life of the elastic member 510. The solution of embodiment two does not require the use of a retainer to restrict the shape of the elastic member 510, and the structure is simple, reliable, and more advantageous.

[0070] However, in the second implementation scheme, the two elastic elements 510 are always in opposition to each other. When the swing plate 300 swings, the forces between the elastic elements 510 are in opposition to each other, that is, the elastic elements 510 cannot cooperate. This will lead to a decrease in energy conversion rate, because the elastic potential energy of the elastic element 510 will be converted into the kinetic energy of the swing plate 300 and the elastic potential energy of the other elastic element 510 at the same time. This will result in a reduction in the kinetic energy that can be provided to the swing plate 300, and the power consumption reduction effect of the motor 200 will be discounted.

[0071] To improve the above issues, please refer to Figure 4The spreading device 020 of this embodiment includes two elastic elements 510, namely a first elastic element 511 and a second elastic element 512. Along the length extension direction of the swing axis of the spinning disc 300, a swing arm 610 is located between the support member 400 and the spinning disc 300. The middle part of the swing arm 610 is connected to the output shaft of the motor 200, and the middle part of the swing arm 610 is also drive-connected to the spinning disc 300, so that the output shaft of the motor 200 is drive-connected to the disc body 310 of the spinning disc 300 through the swing arm 610. The two ends of the length extension direction of the swing arm 610 are respectively connected to the second end of the first elastic element 511 and the second end of the second elastic element 512. When the spinning disc 300 is in the neutral position, the length extension direction of the elastic element 510 points towards the swing center of the spinning disc 300. Specifically, when the spinning disc... When 300 is in the middle position, the length extension directions of both the first elastic element 511 and the second elastic element 512 point to the swing center of the spinning disc 300, and the length extension directions of the first elastic element 511 and the second elastic element 512 coincide and are perpendicular to the set axis a. The first elastic element 511 and the second elastic element 512 are distributed horizontally and symmetrically on both sides of the set axis a. The first elastic element 511 and the second elastic element 512 are both in a stretched state when the spinning disc 300 is stationary, and are also in a stretched state when it swings. When the spinning disc 300 swings, the swing of the spinning disc 300 is converted into the axial deformation of the first elastic element 511 and the second elastic element 512 respectively. When the first elastic element 511 and the second elastic element 512 release elastic potential energy, they can cooperate to drive the spinning disc 300 to swing in the opposite direction.

[0072] This configuration ensures that the first elastic element 511 and the second elastic element 512 are not in a state of mutual antagonism when releasing elastic potential energy, but rather in a state of mutual cooperation. This improves the problem of decreased energy conversion rate, specifically the issue that the elastic potential energy released by one of the first elastic element 511 and the second elastic element 512 is simultaneously converted into the kinetic energy of the swing disc 300 and the elastic potential energy of the other. This further improves the problem of reduced conversion of the elastic potential energy of the first elastic element 511 and the second elastic element 512 into the kinetic energy of the swing disc 300, ensuring that the motor 200 reliably reduces power consumption. In other words, through the centripetal installation of the first elastic element 511 and the second elastic element 512, the first elastic element 511 and the second elastic element 512 will extend simultaneously regardless of the direction in which the swing disc 300 swings. Moreover, the elastic potential energy released by the first elastic element 511 and the second elastic element 512 can provide the torque to restore the swing disc 300 to the neutral position, thereby ensuring that the first elastic element 511 and the second elastic element 512 can cooperate with each other, rather than being antagonistic.

[0073] Further, please refer to Figure 5Extending along the length of the swing axis of the swivel disc 300, the elastic element 510 is located between the support member 400 and the swivel disc 300. Specifically, the elastic element 510 is positioned on a plane parallel to the swing plane of the swivel disc 300. The elastic element 510 is located on the side of the disc body 310 of the swivel disc 300 away from the paddle 320, and the direction of the elastic force provided by the elastic element 510 is perpendicular to the output shaft axis of the motor 200. This arrangement avoids interference from the elastic element 510 in distributing materials by the swivel disc 300 and ensures that the elastic potential energy of the elastic element 510 is converted as much as possible into the power for the reverse swing of the swivel disc 300, thus improving efficiency.

[0074] Of course, in other embodiments, the elastic element 510 may also be disposed on a plane that is not parallel to the swing plane of the swivel disc 300.

[0075] Alternatively, in other embodiments, the first end of the elastic member 510 may also be rotatably connected to the load support 100, etc., without being specifically limited here.

[0076] In this embodiment, please refer to Figure 5 and Figure 6 The swinging component includes a swing arm 610 mounted on the output shaft of the motor 200. The swing disc 300 is connected to the output shaft of the motor 200 via the swing arm 610. The second end of the elastic element 510 is rotatably connected to the end of the swing arm 610. With this configuration, the elastic element 510 can reliably drive the swing disc 300 to swing in the opposite direction.

[0077] In one embodiment, when the swivel disc 300 is in the middle position, the length extension directions of the first elastic member 511 and the second elastic member 512 both point to the swing center of the swivel disc 300. The first elastic member 511 and the second elastic member 512 are asymmetrically distributed on both sides of the set axis a, or the first elastic member 511 and the second elastic member 512 are distributed on the same side of the set axis a, which is not specifically limited here.

[0078] It should be understood that in other embodiments, the number of elastic elements 510 may be increased or decreased as needed, for example, four elastic elements 510, etc., which are not specifically limited here.

[0079] It should be noted that in embodiments where the number of elastic elements 510 is greater than two, including only two centripetally arranged elastic elements 510 is sufficient to address the issue of non-coordination among the elastic elements 510. For example, in an embodiment with four elastic elements 510, two of the elastic elements 510 are a first elastic element 511 and a second elastic element 512, whose length extension direction points towards the swing center of the swing disc 300 when the swing disc 300 is in the neutral position. The length extension direction of the other two elastic elements 510 does not necessarily point towards the center of the swing disc 300. Of course, if the length extension direction of all the elastic elements 510 points towards the swing center of the swing disc 300 when the swing disc 300 is in the neutral position, then all the elastic elements 510 can collaboratively drive the swing disc 300 to swing in the opposite direction.

[0080] The connection method between the output shaft of the motor 200 and the swing arm 610, and the connection method between the swing arm 610 and the swivel disc 300, include but are not limited to plug-in, snap-fit, and welding, and are not specifically limited here.

[0081] It should be understood that in other embodiments, the swing arm 610 is connected to the output shaft of the motor 200, but not to the swivel disc 300, that is, the swivel disc 300 is not connected to the output shaft of the motor 200 via the swing arm 610.

[0082] In this embodiment, please refer to Figure 6 The first elastic element 511 and the second elastic element 512 are centrally symmetrically distributed about the swing center of the swing disc 300. When the swing disc 300 swings, the radial forces exerted by the first elastic element 511 and the second elastic element 512 on the output shaft of the motor 200 can cancel each other out, and the first elastic element 511 and the second elastic element 512 extend or shorten synchronously. In this way, the shaft breakage problem can be improved, that is, the radial component of the force exerted by the first elastic element 511 on the output shaft of the motor 200 and the radial component of the force exerted by the second elastic element 512 on the output shaft of the motor 200 cancel each other out, reducing the risk of shaft breakage caused by the radial force pulling on the output shaft of the motor 200.

[0083] Of course, in embodiments where there are two or more elastic elements 510, it is not necessary for the multiple elastic elements 510 to be centrally symmetrically distributed around the swing center of the swing disc 300. That is, in other embodiments, the multiple elastic elements 510 do not need to be centrally symmetrically distributed around the swing center of the swing disc 300. For example, in other embodiments, the first elastic element 511 and the second elastic element 512 can be distributed on the same side of the set axis a (e.g., Figure 11 (as shown); or, in other embodiments, the plurality of elastic elements 510 may be asymmetrically distributed on both sides of the set axis a; or, the plurality of elastic elements 510 may be symmetrically but not centrally symmetrically distributed on both sides of the set axis a, etc. (e.g.) Figure 12 (As shown), no specific limitations are made here.

[0084] The two elastic elements 510 in this embodiment (i.e., the first elastic element 511 and the second elastic element 512) are similar in their own structure and in their connection with the swing arm 610 and the support 400. Only one of the elastic elements 510 will be described in detail here.

[0085] In this embodiment, please refer to Figure 5 , Figure 13 and Figure 14 The elastic element 510 has a connector 520 at its second end, and the connector 520 has a first shaft hole 521. The swing arm 610 includes two spaced-apart clamping arms 611, each with a second shaft hole 612. The connector 520 is inserted between the two clamping arms 611, and the first shaft hole 521 and the second shaft hole 612 are opposite to each other and a first rotating shaft 613 passes through them. This arrangement ensures easy assembly and stable assembly of the elastic element 510 and the swing arm 610, and ensures that the second end of the elastic element 510 can rotate smoothly around the first rotating shaft 613.

[0086] Furthermore, the support member 400 includes a radial mounting wall 411 disposed on the output shaft of the motor 200, with a fixed position located on the mounting wall 411, and the second end of the elastic member 510 rotatably connected to the mounting wall 411. This arrangement ensures that the elastic member 510 is reliably disposed between the slinger 300 and the support member 400, effectively preventing the elastic member 510 from interfering with the slinger 300 in spreading materials.

[0087] Furthermore, a connecting seat 420 is provided at the fixed position of the mounting wall 411, and the first end of the elastic element 510 is rotatably connected to the support member 400 through the connecting seat 420. The setting of the connecting seat 420 ensures the reliability of the rotatable connection between the first end of the elastic element 510 and the fixed position.

[0088] Optionally, the first end of the elastic element 510 is also provided with a connector 520, and the connecting seat 420 is provided with a insertion hole 421 and a third shaft hole 422 communicating with the insertion hole 421. The connector 520 at the first end of the elastic element 510 is inserted into the insertion hole 421, and the first shaft hole 521 and the third shaft hole 422 are opposite to each other and a second rotating shaft 423 is passed through it. This arrangement ensures the ease of assembly and the stability of the assembly of the elastic element 510 and the connecting seat 420, and ensures that the first end of the elastic element 510 can rotate smoothly around the second rotating shaft 423.

[0089] The connection method between any end of the elastic element 510 and the corresponding connector 520 can be selected as needed; please refer to [reference needed]. Figure 5 and Figure 13In this embodiment, the elastic element 510 includes a spring, and both ends of the spring are provided with connectors 520. Each connector 520 is provided with a helical groove 522. When the spring's coil is screwed into the helical groove 522, the connector 520 is fixed to the spring. This design ensures the ease of connection between the spring and the connector 520, as well as the stability after connection.

[0090] Furthermore, the connector 520 is connected to a retaining flange 523, and the end of the spring can abut against the retaining flange 523. The retaining flange 523 is used to prevent the spring from displacing along its axial direction. This design not only improves the stress concentration problem of the spring, but also ensures that the spring can adapt well to various complex and harsh working conditions such as vibration, high-frequency tension, and impact, thus greatly improving the life and reliability of the spring.

[0091] Of course, in other embodiments, the elastic element 510 includes a spring, and the connector 520 connected to its end is a hook formed by the spring itself; or, in other embodiments, the connector 520 is a hook, and the end of the spring is wound to form a constricted structure so that the hook is embedded in the constricted structure at the end of the spring, thus reducing the problem of spring stress concentration. Alternatively, in other embodiments, the structures of the two elastic elements 510 can be different, and the connection methods of the first end and the second end of the two elastic elements 510 to the connecting seat 420 and the swing arm 610 can also be different. For example, the first end of the first elastic element 511 is rotatably connected to the connecting seat 420 through the second rotating shaft 423 to be connected to the swing plate 300 through the connecting seat 420, while the first end of the second elastic element 512 is directly rotatably connected to the swing plate 300 through the second rotating shaft 423 without going through the connecting seat 420.

[0092] In other embodiments, the elastic element 510 may also include elastic strips, etc., which are not specifically limited here.

[0093] In this embodiment, please refer to Figure 5 The support member 400 is provided with a receiving groove 410, and the elastic member 510 is at least partially located within the receiving groove 410. The groove wall of the receiving groove 410 is the aforementioned mounting wall 411, and the connecting seat 420 is connected to the groove wall of the receiving groove 410. The receiving groove 410 provides a smaller space for accommodating the elastic member 510 and allows the elastic member 510 to swing within the receiving groove 410. Assembling the elastic member 510 in a relatively small space makes it easier to seal and protect it compared to assembling it in a large space. For example, the size of the cover 430 connected to the support member 400 to cover the receiving groove 410 can be made smaller.

[0094] Furthermore, the connecting seat 420 is integrally formed onto the groove wall of the receiving groove 410. Of course, in other embodiments, the connection method between the connecting seat 420 and the groove wall of the receiving groove 410 can also be bonding, fastening with bolts or other fasteners, etc., which are not specifically limited here.

[0095] Furthermore, both elastic elements 510 are embedded in the receiving groove 410, that is, both the first elastic element 511 and the second elastic element 512 are embedded in the receiving groove 410.

[0096] Furthermore, please refer to Figure 5 and Figure 15 The spreading device 020 also includes a shielding cover 430, which is connected to the support member 400 and is used to shield the opening of the receiving groove 410. This arrangement reduces the interference of material on the elastic member 510, ensuring that the elastic member 510 reliably releases its elastic potential energy to drive the swivel disc 300 to swing in the opposite direction.

[0097] The connection methods between the cover 430 and the support 400 include, but are not limited to, snap-fit ​​and connection by fasteners such as bolts.

[0098] It should be noted that the stretching and shortening of each elastic element 510 in this embodiment refers to the change in its length, not the change in its elasticity. That is, stretching and compression do not mean that the elastic element 510 is in a state of providing tension or thrust.

[0099] The unmanned equipment in this embodiment can use the seeding system 110 to seed particulate materials such as seeds. The specific seeding process includes: the motor 200 drives the spinning disc 300 to swing back and forth, and during the swinging process of the spinning disc 300, the first elastic element 511 and the second elastic element 512 undergo elastic deformation, and the elastic potential energy released when the first elastic element 511 and the second elastic element 512 recover can be used to drive the spinning disc 300 to swing in the opposite direction.

[0100] In summary, the seeding device 020 of the present invention can be used in the seeding system 110 of unmanned equipment. The seeding device 020 can reduce the power consumption of the motor 200, improve the problem of severe overheating of the motor 200, and thus help extend the battery life that provides power to the motor 200, effectively improving the problem of motor 200 burnout. Moreover, when the first elastic member 511 and the second elastic member 512 release elastic potential energy, they are not in a state of mutual opposition, but rather cooperate with each other, which can improve the problem of decreased energy conversion rate.

[0101] 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.
