Description

Technical Field

[0001] The utility model relates to the technical field of unmanned equipment, and in particular to a spreading device, a system and unmanned equipment. Background Art

[0002] Unmanned equipment, such as drones and autonomous vehicles, is widely used in the field of plant protection technology, specifically for operations such as seed sowing and watering. Unmanned equipment used for sowing materials such as seeds and fertilizers requires a sowing system to be installed on the unmanned equipment itself. The sowing system typically includes a material box, a feeding device, and a sowing device. The material box is connected to the sowing device via the feeding device. The material box is used to store seeds and other materials. The feeding device is used to transport the materials output from the material box to the sowing device, which is used to sow the materials. The sowing device includes a motor and a spinner connected to the motor. The motor drives the spinner to swing back and forth, thereby beating the materials out.

[0003] Existing spreading devices using oscillating discs have a motor connected to the discs 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 reciprocating oscillation of the discs. However, this transmission method is complex, faces numerous reliability challenges, and is costly. Utility Model Content

[0004] The utility model provides a novel swing-type spinning disc spreading device, in which the output shaft of a motor directly drives the spinning disc, and the reciprocating swing of the spinning disc is achieved by controlling the forward and reverse rotation of the output shaft of the motor. However, using the output shaft of the motor to drive the reciprocating swing of the spinning disc requires the motor to be constantly stopped and accelerated in reverse, resulting in extremely high power consumption and severe heat generation of the motor. This not only affects the battery life of the battery that provides power to the motor, but also easily burns out the motor.

[0005] The spreading device provided by the utility model can be used in the spreading system of unmanned equipment, and the spreading device can reduce the power consumption of the motor, improve the problem of serious motor heating, and thus help to extend the life of the battery that provides power to the motor, and effectively improve the problem of motor burning.

[0061] Please refer to Figure 1 The present disclosure 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.

[0062] Please refer to Figure 1 and Figure 2The unmanned device includes an unmanned device body and a sowing system 110 disposed on the unmanned device body. Specifically, the unmanned device body includes a load support 100, and the sowing system 110 is assembled on the load support 100. The sowing system 110 includes a material box 111, a feeding device 112, and a sowing device 020. The material box 111 is assembled on the load support 100 and connected to the sowing device 020 via the feeding device 112. The material box 111 is used to store materials such as seeds. The feeding device 112 is used to receive materials output by the material box 111 and transport the received materials to the sowing device 020. The sowing device 020 is used to sow the materials. The unmanned device body can refer to the drone body.

[0063] It should be understood that the feeding device 112 is not a necessary structure. In other embodiments, the material box 111 may not be connected to the sowing device 020 through the feeding device 112, that is, the material output by the material box 111 does not need to be transported through the feeding device 112, but directly falls on the sowing device 020 for sowing.

[0064] Please refer to Figure 2 and Figure 3 The spreading device 020 disclosed in the present invention includes a material cover 113, a motor 200, a support 400 and a spinner 300. The material cover 113 is provided with a material port 114, and the material cover 113 is connected between the feeding device 112 and the support 400; the spinner 300 is located between the material cover 113 and the support 400; the motor 200 is assembled on the support 400, and the output shaft of the motor 200 is transmission-connected to the spinner 300, for driving the spinner 300 to swing back and forth around its own swing center on both sides of the set axis a. The swinging spinner 300 can spread the material that falls from the material port 114 between the material cover 113 and the support 400.

[0065] Furthermore, the support member 400 has a first side and a second side disposed opposite each other, the first side being disposed opposite the material cover 113, the spinner 300 being disposed on the first side, the motor 200 being mounted on the second side, and the output shaft of the motor 200 passing through the support member 400 to connect to the spinner 300. This arrangement improves the integration of the spreading device 020.

[0066] The spinning 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 opening 114, and the paddle 320 swings with the disc body 310 and is used to spread the material out.

[0067] Optionally, in some embodiments, the motor 200 may be connected to the spinner 300 via a reduction gearbox, which is not specifically limited herein.

[0068] In the related art, the output shaft of the motor 200 is used to drive the spinner 300 to swing back and forth in forward and reverse rotation, which requires the motor 200 to constantly stop and accelerate in the reverse direction, resulting in extremely high power consumption and severe heat generation of the motor 200, which not only affects the battery life of the battery that provides power to the motor 200, but also easily burns the motor 200.

[0069] To address the aforementioned issues, the spreading device 020 provided herein further includes an elastic mechanism 500. The elastic mechanism 500 is configured to absorb the kinetic energy of the spinner 300 and undergo elastic deformation as the spinner 300 swings, and to drive the spinner 300 to swing in the opposite direction when the elastic potential energy is released. In this manner, the elastic deformation of the elastic mechanism 500 is utilized to absorb stored energy, allowing the elastic mechanism 500 to adapt to the swing frequency of the spinner 300, thereby assisting in deceleration and reverse acceleration of the spinner 300. This reduces energy consumption during sudden stops and reverse acceleration of the motor 200, alleviates the problem of severe heating of the motor 200, and thereby helps extend the battery life of the battery that supplies power to the motor 200, effectively alleviating the problem of motor 200 burning out.

[0070] The elastic mechanism 500 has various implementations, and each implementation will be described in detail below.

[0071] Implementation Method 1

[0072] Please refer to Figure 4 The elastic mechanism 500 is disposed on the swing path of the spinning disc 300. Specifically, the elastic mechanism 500 is connected to the support member 400. When the spinning disc 300 swings and strikes the elastic mechanism 500, the elastic mechanism 500 is elastically deformed by the impact of the spinning disc 300 and drives the spinning disc 300 to swing in the opposite direction when it returns to its original shape. When the swinging spinning disc 300 strikes the elastic mechanism 500, the elastic mechanism 500 compresses to store energy. When it recovers and releases the elastic potential energy, the elastic mechanism 500 provides power for the spinning disc 300 to swing in the opposite direction, thereby reducing the energy consumption of the motor 200.

[0073] Furthermore, the elastic mechanism 500 includes two impact elastic members 501, both of which are connected to the support member 400. One of the two impact elastic members 501 is arranged on the path of the spinner 300 swinging in the first direction, and is used to release elastic potential energy after a collision to drive the spinner 300 to swing in the second direction; the other of the two impact elastic members 501 is arranged on the path of the spinner 300 swinging in the second direction, and is used to release elastic potential energy after a collision to drive the spinner 300 to swing in the first direction; wherein the first direction is opposite to the second direction. This arrangement allows the two impact elastic members 501 to provide elastic potential energy to the spinner 300 as it swings back and forth, driving the spinner 300 to swing in the opposite direction, thereby reliably reducing energy consumption of the motor 200.

[0074] Optionally, the disk body 310 of the spinning tray 300 is coaxially connected to a first swing arm 601 that swings synchronously therewith. The length of the first swing arm 601 extends perpendicularly to the swing axis of the spinning tray 300. When the spinning tray 300 is in the middle position, the length of the first swing arm 601 extends perpendicularly to the set axis a. The two ends of the length of the first swing arm 601 are respectively used to collide with the two impact elastic members 501. The spinning tray 300 and the first swing arm 601 can be directly or indirectly connected, which is not specifically limited here.

[0075] Furthermore, the first swing arm 601 and the two impact elastic members 501 are distributed in a plane parallel to the swing plane of the spinner 300 .

[0076] Of course, in other embodiments, the first swing arm 601 and the two impact elastic members 501 may also be distributed in a plane that is not parallel to the swing plane of the spinner 300 .

[0077] Alternatively, in other embodiments, please refer to Figure 5 The two sides of the swinging direction of the spinning disc 300 are respectively configured to collide with the corresponding impact elastic members 501, etc., which are not specifically limited here.

[0078] Alternatively, see Figure 4 The impact elastic member 501 includes an impact spring 5011 and a base 5012. The impact spring 5011 is connected to the side of the support member 400 facing the material cover 113 via the base 5012. The impact spring 5011 can be impacted by the end of the first swing arm 601 and drive the spinner 300 to swing in the opposite direction when returning to its original state. Of course, in other embodiments, the impact spring 5011 can also be replaced by an elastic rubber block, and the impact spring 5011 or the elastic rubber block can also be directly connected to the support member 400 instead of being connected to the support member 400 via the base 5012. This is not specifically limited here.

[0079] It should be understood that in other embodiments, the elastic mechanism 500 can also be provided on the spinner 300. When the spinner 300 swings, the elastic mechanism 500 swings synchronously with the spinner 300 and can collide with the impact part provided on the support member 400 or the load bracket 100 to compress and store energy.

[0080] Alternatively, in other embodiments, the elastic mechanism 500 may also be disposed on the load bracket 100 . It is only necessary to ensure that the elastic mechanism 500 is located in the swing path of the spinner 300 and can be struck by the spinner 300 . No specific limitation is given here.

[0081] Compressing the elastic mechanism 500 to store energy through impact will cause energy loss due to elastic deformation and sliding between the interface between the elastic mechanism 500 and the component it collides with. During the operation of the spinning disc 300 swinging back and forth and spreading materials, the impact frequency of the elastic mechanism 500 is high and the impact speed is fast. The time for the kinetic energy of the spinning disc 300 to be converted into the elastic potential energy of the elastic mechanism 500 is very short. The elastic mechanism 500 working intermittently will be subjected to high-frequency and powerful impacts, and the entire intermittent structure (i.e., the elastic mechanism 500) will produce large vibrations, resulting in instability of the entire structure and poor reliability. In order to improve the above problems, the present disclosure provides a second embodiment.

[0082] Implementation Method 2

[0083] The elastic mechanism 500 generates elastic deformation to store energy instead of relying on the impact of the spinning tray 300; the elastic mechanism 500 remains connected to the spinning tray 300 when the spinning tray 300 is stationary or oscillating. Embodiment 2 includes multiple specific embodiments, each of which will be described in detail below.

[0084] Example 1

[0085] Please refer to Figure 6 The elastic mechanism 500 includes a torsional elastic member 502, which is disposed at the swinging center of the spinning disc 300. One end of the torsional elastic member 502 is connected to the spinning disc 300, and the other end is connected to the support member 400. The torsional elastic member 502 absorbs the kinetic energy of the spinning disc 300 and undergoes torsional deformation when the spinning disc 300 swings. Specifically, in this embodiment, the torsional elastic member 502 is a spring, which is sleeved on the output shaft of the motor 200. One end of the torsional elastic member 502 is connected to the spinning disc 300, and the other end is connected to the support member 400. When the spinning disc 300 swings, the spinning disc 300 drives the torsional elastic member 502 to twist and store energy. That is, when the torsional elastic member 502 overcomes the torsional return and resets, it drives the spinning disc 300 to rotate in the opposite direction, thereby reducing the energy consumption of the motor 200 driving the spinning disc 300 to swing in the opposite direction.

[0086] Of course, in other embodiments, the torsion elastic member 502 may also be a torsion spring, and the two torsion arms of the torsion spring are respectively connected to the spinner 300 and the support member 400 .

[0087] It should be noted that the torsion in the torsional elastic member 502 is a limitation on its deformation mode, that is, it means that it undergoes torsional deformation after being subjected to the force of the swinging disk 300, rather than a limitation on its structure or shape.

[0088] The torsional elastic member 502 is connected to the spinner 300 and the support member 400 by, but not limited to, welding, or connection with fasteners such as bolts.

[0089] Example 2

[0090] Please refer to Figure 7 The elastic mechanism 500 includes a curved track 401 and a curved elastic member 503 disposed within the curved track 401. The curved track 401 is connected to the support member 400 and centered about the swing center of the spinning disc 300. The curved elastic member 503 is disposed within the curved track 401. The spreading device 020 also includes a first swing arm 601 that swings synchronously with the spinning disc 300. The end of the first swing arm 601 is connected to the curved elastic member 503. When the spinning disc 300 swings, the first swing arm 601 compresses or stretches the curved elastic member 503, and the curved elastic member 503 deforms along the trajectory of the curved track 401. This arrangement ensures that the curved elastic member 503 disposed within the curved track 401 undergoes more reliable elastic deformation, and that the curved elastic member 503 can reliably return to its original position under its own elastic action, thereby reliably driving the spinning disc 300 to swing in the opposite direction.

[0091] Furthermore, the spinning disc 300 is connected to two first swing arms 601, and the two first swing arms 601 swing back and forth with the spinning disc 300, and the ends of the two first swing arms 601 away from the spinning disc 300 are slidably engaged with the arc track 401; the elastic mechanism 500 includes two arc-shaped elastic members 503, and the two arc-shaped elastic members 503 are both arranged in the arc track 401, and one end of the two arc-shaped elastic members 503 is respectively connected to the end of the two first swing arms 601 away from the spinning disc 300, and the other end of the two arc-shaped elastic members 503 is connected to the positioning member 402 connected to the first track, and the two arc-shaped elastic members 503 are respectively located on both sides of the positioning member 402. When the spinning tray 300 swings, one of the first swing arms 601 stretches the corresponding arc-shaped elastic member 503, and the other first swing arm 601 compresses the corresponding arc-shaped elastic member 503. The elastic force released when the two arc-shaped elastic members 503 recover can be used to drive the spinning tray 300 to swing in the opposite direction, ensuring the reliability of using the arc-shaped elastic members 503 to drive the spinning tray 300 to swing in the opposite direction.

[0092] Of course, in other embodiments, the spinning tray 300 is connected to only one first swing arm 601, and the end of the first swing arm 601 away from the spinning tray 300 is slidably engaged with the arc track 401; the elastic mechanism 500 includes two arc-shaped elastic members 503, both of which are arranged in the arc track 401, and one end of the two arc-shaped elastic members 503 is connected to the end of the first swing arm 601 away from the spinning tray 300, and the other ends of the two arc-shaped elastic members 503 are connected to the ends of the arc track 401 in the longitudinal extension direction, and the two arc-shaped elastic members 503 are distributed on both sides of the first swing arm 601; when the spinning tray 300 swings, the first swing arm 601 stretches one arc-shaped elastic member 503 and compresses the other arc-shaped elastic member 503, so that the spinning tray 300 can be driven to swing in the opposite direction by utilizing the elastic force released when the two arc-shaped elastic members 503 recover, thereby ensuring the reliability of utilizing the arc-shaped elastic members 503 to drive the spinning tray 300 to swing in the opposite direction.

[0093] It should be noted that the stretching and compression of the arc-shaped elastic member 503 refers to the change in its length, but does not represent a change in its elasticity, that is, stretching and compression does not mean that the arc-shaped elastic member 503 is in a state of providing tension or thrust.

[0094] It should also be noted that the arc-shaped elastic member 503 may be naturally arc-shaped when not installed in the arc-shaped track 401, or may be arc-shaped when installed in the arc-shaped track 401. The arc-shaped elastic member 503 may be a spring, an elastic strip, or the like, and is not specifically limited here.

[0095] In Example 1, the torsional elastic member 502 is rigidly connected to the spinner 300, resulting in stress concentration at the connection point, prone to wear, and poor reliability. In Example 2, the curved elastic member 503 is positioned within the curved track 401. During tension or compression, there is significant sliding friction between the curved track 401 and the torsional elastic member 502, leading to significant energy loss and hindering motor power consumption. To address these issues, the present disclosure provides a third embodiment.

[0096] Implementation Method 3

[0097] Please refer to Figures 8-12 The elastic mechanism 500 includes a straight elastic member (hereinafter referred to as the elastic member 510). When the spinning tray 300 swings, the swinging motion of the spinning tray 300 is converted into axial deformation of the elastic member 510. This arrangement allows more of the kinetic energy of the spinning tray 300 to be absorbed by the elastic member 510, and more of the elastic potential energy released by the elastic member 510 can be converted into power to drive the spinning tray 300 in the reverse direction, thereby reducing energy loss, improving the connection stability between the elastic member 510 and the spinning tray 300, reducing wear, and further enhancing the reliability of the elastic member 510 in assisting the spinning tray 300 in the reverse direction.

[0098] It should be noted that the straight elastic member refers to an elastic member that is designed to undergo axial deformation when subjected to an external force, such as a spring or rubber that can be stretched or compressed in the length direction.

[0099] The third embodiment includes a plurality of specific embodiments. In some embodiments, the linear motion assembly 700 of the elastic mechanism 500 is used to convert the circular motion of the spinner 300 into linear motion, so that the elastic member 510 is linearly stretched or compressed. That is, the spinner 300 is driven by the linear motion assembly 700, and the linear motion assembly 700 is used to convert the swinging motion of the spinner 300 into linear motion and cause the elastic member 510 to undergo axial deformation. In other embodiments, the linear motion assembly 700 is not required. The following will describe the various embodiments in detail.

[0100] Example 3

[0101] Please refer to Figure 8 The spreading device 020 also includes a second swing arm 602 that swings synchronously with the spinning disc 300. Specifically, one end of the second swing arm 602 is coaxially connected to the disc body 310 of the spinning disc 300. The linear motion assembly 700 includes a first slide rail 711 and a second slide rail 712. The other end of the second swing arm 602 slides with the first slide rail 711; the first slide rail 711 slides with the second slide rail 712, and the extension direction of the first slide rail 711 is perpendicular to the second slide rail 712; the elastic member 510 is arranged on the first slide rail 711; when the spinning disc 300 swings, the end of the second swing arm 602 slides in the first slide rail 711, and drives the first slide rail 711 to slide along the second slide rail 712, so that the elastic member 510 undergoes axial deformation. By configuring the two-dimensional slide rail assembly, the swinging motion of the spinner 300 is converted into linear motion within the first slide rail 711, and the second swing arm 602 is used to extend and retract the elastic member 510. When the elastic member 510 recovers, the elastic potential energy released by the elastic member 510 can be used to reliably drive the second swing arm 602 and the spinner 300 to swing in the opposite direction synchronously, thereby ensuring the reliability of the spinner 300 utilizing the elastic action of the elastic member 510 to coordinate its reciprocating swing, reducing the loss of elastic potential energy, and improving reliability.

[0102] Furthermore, a second slide rail 712 is connected to a first side of the support member 400, and its length extends parallel to the set axis a. The second swing arm 602 is located on the side of the tray body 310 facing the support member 400. The elastic mechanism 500 includes two elastic members 510. The first slide rail 711 has a linear slot. Both elastic members 510 are disposed within the slot of the first slide rail 711. The first ends of the two elastic members 510 are respectively connected to the ends of the first slide rail 711 in the longitudinal direction, and the second ends of the two elastic members 510 are slidably connected to the end of the second swing arm 602 disposed in the slot of the first slide rail 711. When the spinner tray 300 swings, the second swing arm 602 swings synchronously, compressing one elastic member 510 and stretching the other elastic member 510. In this way, the two elastic members 510 can cooperatively drive the second swing arm 602 and the spinner tray 300 to swing in opposite directions.

[0103] Example 4

[0104] Please refer to Figure 9 The spreading device 020 also includes a second swing arm 602 that swings synchronously with the spinning disc 300. Specifically, one end of the second swing arm 602 is coaxially connected to the disc body 310 of the spinning disc 300. The linear motion assembly 700 includes a first slide rail 711 and a second slide rail 712. The second slide rail 712 is connected to the support member 400. The end of the second swing arm 602 slides with the first slide rail 711; the first slide rail 711 slides with the second slide rail 712, and the extension direction of the first slide rail 711 is perpendicular to the second slide rail 712; the elastic member 510 is arranged on the second slide rail 712; when the spinning disc 300 swings, the end of the second swing arm 602 slides in the first slide rail 711, and drives the first slide rail 711 to slide along the second slide rail 712, so that the elastic member 510 undergoes axial deformation. By configuring the two-dimensional slide rail assembly, the swinging motion of the spinner 300 is converted into the linear motion of the first slide rail 711, and the first slide rail 711 is used to extend and retract the elastic member 510. When the elastic member 510 recovers, the elastic potential energy released by the elastic member 510 can be used to reliably drive the second swing arm 602 and the spinner 300 to swing in the opposite direction synchronously, thereby ensuring the reliability of the spinner 300 utilizing the elastic action of the elastic member 510 to coordinate its reciprocating swing, reducing the loss of elastic potential energy, and improving reliability.

[0105] Furthermore, the first slide rail 711 is connected to the slider 713, and the slider 713 is slidably connected to the second slide rail 712, that is, the first slide rail 711 slides with the second slide rail 712 via the slider 713. The elastic member 510 is disposed within the second slide rail 712, and the ends of the elastic member 510 are respectively connected to the second slide rail 712 and the slider 713. When the spinning tray 300 swings, the end of the second swing arm 602 away from the spinning tray 300 slides along the first slide rail 711, driving the first slide rail 711 to drive the slider 713 to slide within the second slide rail 712, thereby causing the elastic member 510 to expand and contract via the slider 713. When the elastic member 510 recovers, the elastic member 510 causes the slider 713 to slide in the opposite direction, and the first slide rail 711 drives the second swing arm 602 and the spinning tray 300 to swing in the opposite direction.

[0106] Furthermore, the length extension direction of the first slide rail 711 is parallel to the length extension direction of the set axis a. This arrangement ensures that when the spinner 300 drives the second swing arm 602 to swing synchronously, the second swing arm 602 sliding in the first slide rail 711 can reliably drive the first slide rail 711 to drive the slider 713 to slide in the second slide rail 712.

[0107] Optionally, the first slide rail 711 and the slider 713 are connected at an angle, and the two roughly form a "T" shape, and the end of the slider 713 away from the first slide rail 711 is slidably engaged with the second slide rail 712.

[0108] The included angle between the first slide rail 711 and the slider 713 is not specifically limited, and includes but is not limited to 90°, 85°, and 80°.

[0109] Of course, in other embodiments, the first slide rail 711 and the slider 713 are connected at an angle, and the two roughly form an "L" shape.

[0110] The number of elastic mechanisms 500 can be selected as needed. In this embodiment, the spreading device 020 includes two elastic mechanisms 500, which can be understood as the spreading device 020 including two elastic members 510 and two linear motion assemblies 700. The two elastic members 510 and the two linear motion assemblies 700 are matched in a one-to-one manner. When the spinning disc 300 swings, the two sets of elastic members 510 and linear motion assemblies 700 can be used to cause the spinning disc 300 to swing in the opposite direction, ensuring the reliability of the elastic members 510 causing the spinning disc 300 to swing in the opposite direction. Of course, in other embodiments, the number of elastic mechanisms 500 can be increased or decreased as needed, and this is not specifically limited here.

[0111] Furthermore, the middle portion of the second swing arm 602 is coaxially connected to the spinner 300, and both ends of the second swing arm 602 in the length extension direction are respectively slidably engaged with the first slide rails 711 of the two linear motion assemblies 700; in this way, the same second swing arm 602 can be used to simultaneously cause the two elastic members 510 to undergo elastic deformation.

[0112] Optionally, the two elastic mechanisms 500 are symmetrically arranged about the swing center of the spinning disc 300, and the output shaft of the motor 200 is connected to the spinning disc 300 via a second swing arm 602. When the spinning disc 300 swings, the radial forces exerted on the output shaft of the motor 200 by the elastic members 510 of the two elastic mechanisms 500 offset each other, and the elastic members 510 of the two elastic mechanisms 500 extend or contract synchronously. This alleviates the problem of the elastic members 510 exerting radial forces on the output shaft of the motor 200, which can easily cause the output shaft of the motor 200 to be pulled and break.

[0113] The connection method between the output shaft of the motor 200 and the second swing arm 602 includes but is not limited to plugging and welding.

[0114] Furthermore, the elastic members 510 of the two elastic mechanisms 500 are symmetrically distributed on both sides of the set axis a, that is, the two elastic members 510 are symmetrically distributed on both sides of the set axis a in the horizontal direction.

[0115] Optionally, when the spinning tray 300 is in the middle position, the length extension directions of the two elastic members 510 are both directed towards the swing center of the spinning tray 300. The spinning tray 300 being in the middle position may mean that the spinning tray 300 is not affected by the motor 200 and the elastic members 510 and is in a stationary position.

[0116] Example 5

[0117] Please refer to Figure 10 The spreading device 020 also includes a second swing arm 602 that swings synchronously with the spinning disc 300. Specifically, one end of the second swing arm 602 is coaxially connected to the disc body 310 of the spinning disc 300. The linear motion assembly 700 includes a first slide rail 711 and a second slide rail 712. The second slide rail 712 is connected to the support member 400. The end of the second swing arm 602 slides with the first slide rail 711; the first slide rail 711 slides with the second slide rail 712, and the extension direction of the first slide rail 711 is perpendicular to the second slide rail 712; the elastic member 510 is arranged on the second slide rail 712; when the spinning disc 300 swings, the end of the second swing arm 602 slides in the first slide rail 711, and drives the first slide rail 711 to slide along the second slide rail 712, so that the elastic member 510 undergoes axial deformation. By configuring the two-dimensional slide rail assembly, the swinging motion of the spinner 300 is converted into the linear motion of the first slide rail 711, and the first slide rail 711 is used to extend and retract the elastic member 510. When the elastic member 510 recovers, the elastic potential energy released by the elastic member 510 can be used to reliably drive the second swing arm 602 and the spinner 300 to swing in the opposite direction synchronously, thereby ensuring the reliability of the spinner 300 utilizing the elastic action of the elastic member 510 to coordinate its reciprocating swing, reducing the loss of elastic potential energy, and improving reliability.

[0118] Furthermore, the linear motion assembly 700 includes two sliders 713 and two second slide rails 712; the elastic mechanism 500 includes two elastic members 510, the length extension direction of the first slide rail 711 coincides with the set axis a, and the two elastic members 510 are distributed on both sides of the set axis a at intervals in the horizontal direction; the two second slide rails 712 are connected to the support member 400 oppositely and at intervals; the two elastic members 510 are arranged in a one-to-one correspondence with the two second slide rails 712, that is, an elastic member 510 is provided in each second slide rail 712; the two sliders 713 are both connected to the first slide rail 711, and the two sliders 713 are connected to the two second slide rails 712 in a one-to-one correspondence, and the two ends of each elastic member 510 are respectively connected to the corresponding slider 713 and the second slide rail 712. When the spinning tray 300 drives the second swing arm 602 to swing synchronously, the second swing arm 602 slides in the first slide rail 711, and drives the first slide rail 711 to drive the two sliders 713 to slide in their respective second slide rails 712, so that one slider 713 drives the corresponding elastic member 510 to extend, while the other slider 713 drives the corresponding elastic member 510 to contract. In this way, when the two elastic members 510 recover and release their elastic potential energy, the corresponding slider 713 is driven to return to its original position, and the slider 713 drives the first slide rail 711 to drive the second swing arm 602 and the spinning tray 300 to swing in the opposite direction.

[0119] Example 6

[0120] Please refer to Figure 11 The linear motion assembly 700 includes a gear 721 and a rack 722. The gear 721 is connected to the spinning disc 300 and is set at the swing center of the spinning disc 300. It rotates with the swing of the spinning disc 300. The gear 721 is engaged with the rack 722. When the spinning disc 300 swings and drives the gear 721 to rotate, the gear 721 drives the rack 722 to move along its length extension direction, and the rack 722 can cause the elastic member 510 to undergo axial deformation.

[0121] Furthermore, the rack 722 is slidably connected to the support member 400 and is located on the first side of the support member 400. The sliding direction of the rack 722 is perpendicular to the set axis a. Specifically, the support member 400 is connected to the slider 713, the rack 722 is provided with a slide groove 714, and the slider 713 and the slide groove 714 are slidably matched; the support member 400 is also provided with a fourth slide rail 403, and the length extension direction of the fourth slide rail 403 is perpendicular to the set axis a; the elastic member 510 is provided on the fourth slide rail 4 03, one end of the elastic member 510 is connected to the fourth slide rail 403, and the other end is connected to the rack 722; when the swing tray 300 swings and drives the gear 721 to rotate, the gear 721 drives the rack 722 to slide relative to the support member 400, and the rack 722 can stretch or shorten the elastic member 510. When the elastic member 510 recovers and releases its elastic potential energy, the rack 722 is driven to reset and drive the gear 721 to rotate in the opposite direction, so that the gear 721 drives the swing tray 300 to swing in the opposite direction.

[0122] Furthermore, the elastic mechanism 500 includes two elastic members 510. The support member 400 is provided with two fourth slide rails 403, and the two elastic members 510 are arranged in a one-to-one correspondence with the two fourth slide rails 403. The two ends of the rack 722 in the longitudinal direction are respectively connected to the two elastic members 510. When the spinning tray 300 swings, the rack 722 causes one of the elastic members 510 to contract and the other to stretch. When the two elastic members 510 recover and release their elastic potential energy, they cooperate to drive the rack 722 to reset, and the rack 722 drives the gear 721 to rotate in the opposite direction, thereby driving the gear 721 to swing the spinning tray 300 in the opposite direction.

[0123] Example 7

[0124] Please refer to Figure 12 The linear motion assembly 700 includes a sliding member 731, a third slide rail 732, and a rocker arm 733. The sliding member 731 slidably engages the third slide rail 732. The rocker arm 733 is pivotally connected to the sliding member 731 and the spinner 300 at both ends. When the spinner 300 swings and drives the rocker arm 733 to swing, the rocker arm 733 drives the sliding member 731 to slide relative to the third slide rail 732, and the sliding member 731 causes the elastic member 510 to axially deform. When the elastic member 510 recovers and releases its elastic potential energy, the elastic member 510 drives the sliding member 731 to slide in the opposite direction relative to the third slide rail 732. The sliding member 731 drives the rocker arm 733 to swing in the opposite direction, and the rocker arm 733 drives the spinner 300 to swing in the opposite direction.

[0125] The number of elastic mechanisms 500 can be selected as needed; the spreading device 020 of this embodiment includes two elastic mechanisms 500, which can be understood as the spreading device 020 including two elastic members 510 and two linear motion assemblies 700, the two elastic members 510 and the third slide rails 732 of the two linear motion assemblies 700 are arranged in a one-to-one correspondence, and the third slide rails 732 are connected to the first side of the support member 400, and the elastic member 510 is arranged in the corresponding third slide rail 732; the spreading device 020 also includes a disc body 310 coaxial with the spinner 300 The second swing arm 602 is connected, and the two ends of the second swing arm 602 in the length extension direction are respectively pivoted to one end of the swing rod 733 of the two linear motion components 700, that is, the swing rod 733 is pivoted to the spinner plate 300 through the second swing arm 602, and the other ends of the swing rod 733 of the two linear motion components 700 slide with their respective corresponding sliding members 731, and the sliding members 731 of the two linear motion components 700 slide with their respective corresponding third slide rails 732, and the two ends of the elastic member 510 are respectively connected to the corresponding third slide rails 732 and the sliding member 731. When the spinning tray 300 swings, the second swing arm 602 swings synchronously, driving the two swing rods 733 to swing. The swing rods 733 drive the corresponding sliding members 731 to slide within the third slide rails 732, so that the two sliding members 731 can synchronously extend or shorten the two elastic members 510. When the two elastic members 510 recover and release their elastic potential energy, they drive their corresponding sliding members 731 to slide in the opposite direction, so that the sliding members 731 drive the swing rods 733 to swing in the opposite direction, and the swing rods 733 drive the spinning tray 300 to swing in the opposite direction. Of course, in other embodiments, the number of elastic mechanisms 500 can be increased or decreased as needed, and is not specifically limited here.

[0126] Optionally, the two elastic mechanisms 500 are symmetrically arranged about the swing center of the spinning disc 300, and the output shaft of the motor 200 is connected to the spinning disc 300 via a second swing arm 602. When the spinning disc 300 swings, the radial forces exerted on the output shaft of the motor 200 by the elastic members 510 of the two elastic mechanisms 500 offset each other, and the elastic members 510 of the two elastic mechanisms 500 extend or contract synchronously. This alleviates the problem of the elastic members 510 exerting radial forces on the output shaft of the motor 200, which can easily cause the output shaft of the motor 200 to be pulled and break.

[0127] The connection method between the output shaft of the motor 200 and the second swing arm 602 includes but is not limited to plugging and welding.

[0128] Furthermore, the two elastic mechanisms 500 are symmetrically distributed on both sides of the set axis a, and the two elastic members 510 are symmetrically distributed on both sides of the set axis a in the horizontal direction.

[0129] Optionally, when the spinner 300 is in the middle position, the length extension directions of the two elastic members 510 are both directed towards the swing center of the spinner 300. The spinner 300 being in the middle position may mean that the spinner 300 is not affected by the motor 200 and the elastic members 510 and is in a stationary position.

[0130] In the above-mentioned embodiments 3-7, when the kinetic energy of the swinging disk 300 is converted into the elastic potential energy of the elastic member 510, friction occurs between the first and second rails 711 and 712 because the first rail 711 of the third embodiment is subjected to a force in a direction other than the length of the second rail 712. In the fourth and fifth embodiments, the second swing arm 602 is subjected to a force in a direction other than the length of the first rail 711, resulting in friction between the second swing arm 602 and the first rail 711. In the sixth embodiment, the slider 713 is also subjected to a force in a direction other than the length of the slot 714, resulting in friction when the rack 722 slides. Furthermore, in the seventh embodiment, the slider 731 is subjected to a force in a direction other than the length of the third rail 732, resulting in friction between the slider 731 and the third rail 732. This results in a reduced conversion rate of the elastic potential energy. Furthermore, while the third and seventh embodiments convert the swinging disk 300 into linear motion through the linear motion assembly 700, the linear motion assembly 700 itself suffers from a complex structure, requiring a large assembly space, and exhibiting low reliability. In order to improve the above-mentioned problems, Example 8 is proposed.

[0131] Example 8

[0132] Please refer to Figure 13 The first end of the elastic member 510 is connected to a fixed position and is rotationally connected to an entity at the fixed position. Specifically, the first end of the elastic member 510 is rotationally connected to the support member 400, that is, the entity at the fixed position is the support member 400. The second end of the elastic member 510 is rotationally connected to the spinning tray 300 or an oscillating member that oscillates synchronously with the spinning tray 300. When the spinning tray 300 oscillates, the second end of the elastic member 510 oscillates with the spinning tray 300 and simultaneously rotates about the position to which it is connected. The first end of the elastic member 510 does not oscillate with the spinning tray 300, but it also rotates about the fixed position to which it is connected. As a result, the elastic member 510 can maintain a straight shape during the swinging of the second end of the elastic member 510. The swinging motion of the spinning tray 300 is converted into axial deformation of the elastic member 510. When the elastic member 510 releases its elastic potential energy, it can drive the spinning tray 300 to oscillate in the opposite direction. With such an arrangement, there is no need to additionally set up a linear motion component 700, and the swinging circular motion is converted into linear motion. In addition, the variable length characteristic of the elastic member 510 is utilized to directly absorb and release energy during the circular motion, thereby avoiding unnecessary energy loss and improving the energy conversion rate. More energy can be converted into the elastic potential energy of the elastic member 510, thereby utilizing the elastic potential energy of the elastic member 510 to fully reduce the energy consumption of the motor 200 driving the spinner 300 to rotate back and forth.

[0133] Further, please refer to Figure 14 The elastic member 510 is positioned between the support member 400 and the spinning disc 300 along the longitudinal extension of the swing axis of the spinning disc 300. Specifically, the elastic member 510 is positioned on a plane parallel to the swing plane of the spinning disc 300. Specifically, the elastic member 510 is positioned on the side of the spinning disc 300 body 310 facing away from the paddle 320, and the direction of the elastic force provided by the elastic member 510 is perpendicular to the axial direction of the output shaft of the motor 200. This arrangement prevents the elastic member 510 from interfering with the spreading of the material by the spinning disc 300 and ensures that the elastic potential energy of the elastic member 510 is converted as much as possible into power for the reverse swing of the spinning disc 300, thereby improving efficiency.

[0134] Of course, in other embodiments, the elastic member 510 may also be disposed on the plane on which the spinner 300 swings.

[0135] Alternatively, in other embodiments, the first end of the elastic member 510 may also be rotatably connected to the load bracket 100 , etc., which is not specifically limited here.

[0136] In this embodiment, please refer to Figure 14 and Figure 15 The swing member includes a third swing arm 610 (also called a swing arm member) arranged on the output shaft of the motor 200, and the second end of the elastic member 510 is rotatably connected to the end of the third swing arm 610; with this arrangement, the elastic member 510 can reliably drive the spinner 300 to swing in the opposite direction.

[0137] Furthermore, the elastic mechanism 500 includes two elastic members 510, namely a first elastic member 511 and a second elastic member 512. A third swing arm 610 is positioned between the support member 400 and the spinning disc 300 along the longitudinal direction of the swing axis of the spinning disc 300. The middle portion of the third swing arm 610 is connected to the output shaft of the motor 200. The middle portion of the third swing arm 610 is also transmission-connected to the spinning disc 300, such that the output shaft of the motor 200 is transmission-connected to the disc body 310 of the spinning disc 300 via the third swing arm 610. The ends of the third swing arm 610 along the longitudinal direction are respectively connected to the second end of the first elastic member 511 and the second end of the second elastic member 512. This arrangement allows the two elastic members 510 to reliably drive the spinning disc 300 to swing in the opposite direction.

[0138] It should be understood that in other embodiments, the number of elastic members 510 may be increased or decreased as needed, and is not specifically limited here.

[0139] The connection method between the output shaft of the motor 200 and the third swing arm 610, and the connection method between the third swing arm 610 and the spinner 300 include but are not limited to plugging, clamping, and welding, which are not specifically limited here.

[0140] It should be understood that in other embodiments, the third swing arm 610 is connected to the output shaft of the motor 200 but is not connected to the spinneret 300 , that is, the spinneret 300 is not connected to the output shaft of the motor 200 via the third swing arm 610 .

[0141] In this embodiment, please refer to Figure 15 The first elastic member 511 and the second elastic member 512 are centrally symmetrically distributed about the swing center of the spinning disk 300. When the spinning disk 300 swings, the radial forces applied by the first elastic member 511 and the second elastic member 512 to the output shaft of the motor 200 can offset each other, and the first elastic member 511 and the second elastic member 512 extend or shorten synchronously. In this way, the problem of shaft breakage can be improved. That is, the radial force component of the output shaft of the motor 200 exerted by the first elastic member 511 and the radial force component of the output shaft of the motor 200 exerted by the second elastic member 512 offset each other, thereby improving the problem of the risk of the output shaft of the motor 200 being pulled by the radial force component and causing shaft breakage.

[0142] Of course, in embodiments where the number of elastic members 510 is two or more, it is not necessary for the multiple elastic members 510 to be centrally symmetrically distributed about the swing center of the spinner 300. In other embodiments, the multiple elastic members 510 do not need to be centrally symmetrically distributed about the swing center of the spinner 300. For example, in other embodiments, the multiple elastic members 510 may be distributed on the same side of the set axis a; or, in other embodiments, the multiple elastic members 510 may be asymmetrically distributed on both sides of the set axis a; or, the multiple elastic members 510 may be symmetrically but non-centrally symmetrically distributed on both sides of the set axis a, etc., and this is not specifically limited herein.

[0143] In this embodiment, please refer to Figure 15When the spinning tray 300 is in the middle position, the length extension direction of the elastic member 510 points to the swing center of the spinning tray 300; specifically, the length extension directions of the first elastic member 511 and the second elastic member 512 both point to the swing center of the spinning tray 300, and the length extension direction of the first elastic member 511 and the length extension direction of the second elastic member 512 coincide with and are perpendicular to the set axis a, and the first elastic member 511 and the second elastic member 512 are distributed on both sides of the set axis a at intervals in the horizontal direction; when the spinning tray 300 swings, the swinging of the spinning tray 300 is converted into axial deformation of each of the two elastic members 510, and the two elastic members 510 can cooperatively drive the spinning tray 300 to swing in the opposite direction when releasing elastic potential energy. Such an arrangement ensures that the two elastic members 510 are not in a state of mutual opposition when releasing elastic potential energy, but rather cooperate with each other, thereby improving the problem of decreased energy conversion efficiency. That is, it improves the problem that the elastic potential energy released by one elastic member 510 is simultaneously converted into kinetic energy of the spinner 300 and the elastic potential energy of the other elastic member 510, thereby improving the problem that the elastic potential energy of the elastic member 510 is converted into reduced kinetic energy of the spinner 300, ensuring that the power consumption of the motor 200 is reliably reduced. That is, by the centripetal installation of the elastic member 510, the first elastic member 511 and the second elastic member 512 are simultaneously extended regardless of the direction in which the spinner 300 swings, and the elastic potential energy released by the first elastic member 511 and the second elastic member 512 can provide torque for returning the spinner 300 to its neutral position, thereby ensuring that the first elastic member 511 and the second elastic member 512 can cooperate with each other rather than oppose each other.

[0144] Of course, in other embodiments, when the spinner 300 is in the middle position, the length extension direction of the elastic member 510 may not point to the swing center of the spinner 300; or, in other embodiments, when the spinner 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 spinner 300, and the first elastic member 511 and the second elastic member 512 are symmetrically or asymmetrically distributed on both sides of the set axis a, and the length extension direction of the first elastic member 511 and the length extension direction of the second elastic member 512 do not coincide with each other and are not perpendicular to the set axis a, which is not specifically limited herein.

[0145] The two elastic members 510 (i.e., the first elastic member 511 and the second elastic member 512) of this embodiment are similar in their own structures and their connection methods with the third swing arm 610 and the support member 400. Only one of the elastic members 510 is introduced in detail here.

[0146] In this embodiment, please refer to Figure 14 、 Figure 16 and Figure 17The second end of the elastic member 510 is provided with a connector 520, which is provided with a first axial hole 521. The third swing arm 610 includes two spaced-apart clamping arms 611, each of which is provided with a second axial hole 612. The connector 520 is inserted between the two clamping arms 611, with the first axial hole 521 and the second axial hole 612 facing each other and passing through a first rotating shaft 613. This arrangement ensures easy and stable assembly of the elastic member 510 and the third swing arm 610, and ensures that the second end of the elastic member 510 can rotate smoothly about the first rotating shaft 613.

[0147] Furthermore, the support member 400 includes a mounting wall 411 disposed radially of the output shaft of the motor 200. The fixed position is located on the mounting wall 411, and the second end of the elastic member 510 is rotatably connected to the mounting wall 411. This arrangement ensures that the elastic member 510 is reliably disposed between the spinner 300 and the support member 400, effectively preventing the elastic member 510 from interfering with the spinner 300 in spreading the material.

[0148] Furthermore, a connecting seat 420 is provided at a fixed position of the mounting wall 411, and the first end of the elastic member 510 is rotatably connected to the support member 400 via the connecting seat 420. The provision of the connecting seat 420 ensures the reliability of the rotatable connection between the first end of the elastic member 510 and the fixed position.

[0149] Optionally, the first end of the elastic member 510 is also provided with a connector 520, and the connecting base 420 is provided with an insertion hole 421 and a third shaft hole 422 connected to the insertion hole 421. The connector 520 at the first end of the elastic member 510 is inserted into the insertion hole 421. The first shaft hole 521 and the third shaft hole 422 are opposite and pass through the second rotation axis 423. This arrangement ensures easy and stable assembly of the elastic member 510 and the connecting base 420, and ensures that the first end of the elastic member 510 can rotate smoothly about the second rotation axis 423.

[0150] The connection method between any end of the elastic member 510 and the corresponding connector 520 can be selected as needed; please refer to Figure 14 and Figure 16 In this embodiment, the elastic member 510 includes a spring, each end of which is provided with a connector 520. The connector 520 is provided with a spiral groove 522. When the coil of the spring is screwed into the spiral groove 522, the connector 520 and the spring are fixed. This arrangement ensures easy operation and stability of the connection between the spring and the connector 520.

[0151] Furthermore, connector 520 is connected to a rib 523, against which the end of the spring abuts, preventing the spring from axially displacing. This arrangement not only alleviates stress concentration in 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, significantly improving the spring's lifespan and reliability.

[0152] Of course, in other embodiments, the elastic member 510 includes a spring, and the connecting head 520 connected to its end is a spring itself wound to form a hook; or, in other embodiments, the connecting head 520 is a hook, and the end of the spring is wound to form a necking structure, so that the hook can be embedded in the necking structure of the spring end, so that the problem of spring stress concentration can be alleviated.

[0153] In other embodiments, the elastic member 510 may further include an elastic rubber strip, etc., which is not specifically limited here.

[0154] In this embodiment, please refer to Figure 14 The support member 400 is provided with a receiving groove 410, and the elastic member 510 is at least partially located in 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 provision of the receiving groove 410 provides a relatively small space for accommodating the elastic member 510 and allows the elastic member 510 to swing within the receiving groove 410. Compared with assembling the elastic member 510 in a large space, assembling the elastic member 510 in a relatively small space is easier to seal and protect. For example, the size of the shielding cover 430 connected to the support member 400 for shielding the receiving groove 410 can be made smaller.

[0155] Furthermore, the connecting seat 420 is directly integrally formed on the wall of the receiving groove 410. Of course, in other embodiments, the connection method of the connecting seat 420 and the wall of the receiving groove 410 can also be bonding, connecting with fasteners such as bolts, etc., which is not specifically limited here.

[0156] Furthermore, the two elastic members 510 are both embedded in the receiving groove 410 , that is, the first elastic member 511 and the second elastic member 512 are both embedded in the receiving groove 410 .

[0157] Further, please refer to Figure 14 and Figure 18 The spreading device 020 further includes a shielding cover 430 connected to the support member 400 and used to shield the notch of the receiving groove 410. This arrangement can reduce the interference of the material on the elastic member 510, thereby ensuring that the elastic member 510 reliably releases elastic potential energy to drive the spinner 300 to swing in the opposite direction.

[0158] The connection method between the shielding cover 430 and the support member 400 includes but is not limited to clamping, and connection through fasteners such as bolts.

[0159] In this embodiment, the first elastic member 511 and the second elastic member 512 are both in a stretched state when the spinner 300 is stationary, and are also in a stretched state when the spinner 300 is swinging; that is, the first elastic member 511 and the second elastic member 512 are in a stretched state regardless of whether they are in a stationary state or a swinging state, which is beneficial to improving the state stability of the first elastic member 511 and the second elastic member 512 and ensuring the consistency of the elastic force provided by the first elastic member 511 and the second elastic member 512.

[0160] Of course, in other embodiments, the first elastic member 511 and the second elastic member 512 are both in a stretched state when the spinner 300 is swinging, and are in a natural state (i.e., neither stretched nor compressed) when the spinner 300 is stationary; such a configuration can extend the service life of the first elastic member 511 and the second elastic member 512.

[0161] Alternatively, in other embodiments, the first elastic member 511 and the second elastic member 512 are both in a compressed state when the spinner 300 is stationary, and in a stretched state when the spinner 300 is swinging.

[0162] It should be understood that in other embodiments, the second end of the elastic member 510 can also be connected to a position of the spinner 300 away from its swing center, and the elastic direction provided by the elastic member 510 is not perpendicular to the axial direction of the output shaft of the motor 200; illustratively, the second end of the first elastic member 511 and the second end of the second elastic member 512 are both connected to a position of the spinner 300 away from its swing center, and the first elastic member 511 and the second elastic member 512 are respectively located on both sides of the set axis a. When the spinner 300 swings, one of the first elastic member 511 and the second elastic member 512 extends and the other shortens. In this way, the first elastic member 511 and the second elastic member 512 can also be used to cooperate to drive the spinner 300 to swing in the opposite direction.

[0163] It should be noted that the stretching and shortening of each elastic member 510 disclosed herein refers to a change in its length, and does not represent a change in its elasticity, that is, stretching and compression does not mean that the elastic member 510 is in a state of providing tension or thrust.

[0164] The unmanned equipment disclosed herein can utilize the spreading system 110 to spread granular materials such as seeds. The specific spreading process includes: the motor 200 drives the spinner 300 to swing back and forth, and during the swinging of the spinner 300, the elastic mechanism 500 undergoes elastic deformation, and the elastic potential energy released when the elastic mechanism 500 recovers can be utilized to drive the spinner 300 to swing in the opposite direction.

[0165] To sum up, the spreading device 020 of the present invention can be used in the spreading system 110 of unmanned equipment. The spreading device 020 can reduce the power consumption of the motor 200, improve the problem of severe heating of the motor 200, and thus help to extend the battery life of the battery that provides power to the motor 200, and effectively improve the problem of burning of the motor 200.

[0166] The above are merely preferred embodiments and examples of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. Furthermore, non-inconsistent implementations and examples may be combined or replaced with one another.
