[0048] It should be noted that the structure and working principle of the unmanned equipment body are similar to those of related technologies and will not be repeated here.

[0049] The spreading device includes a material box and a spreading mechanism 010 (such as Figure 1 As shown), the material box is connected to the unmanned equipment body, and the spreading mechanism 010 is connected to the material box. The material box is used to store materials to be spread, and can transport the stored materials to the spreading mechanism 010 so that the materials can be spread out using the spreading mechanism 010.

[0050] It should be understood that in other embodiments, the spreading mechanism 010 can also be connected to the unmanned equipment body, which is not specifically limited here.

[0051] It should be noted that the above-mentioned spreading device and spreading mechanism 010 can also be used independently, for example, the spreading device can also be mounted on agricultural machinery such as a tractor for use.

[0052] Optionally, the material box is provided with a discharge port, and the discharge port of the material box is distributed relative to the sowing mechanism 010, so that the material stored in the material box can be transported to the sowing mechanism 010 through the discharge port; wherein, the material stored in the material box can be transported from the discharge port to the sowing mechanism 010 under the action of its own weight.

[0053] It should be understood that in other embodiments, the spreading device further includes a conveying assembly, which is disposed at the discharge port and is used to output the material stored in the material box from the discharge port and convey it to the spreading mechanism 010. The above-mentioned conveying assembly includes but is not limited to a conveyor belt assembly, an auger assembly, etc., which are not specifically limited here.

[0054] Please refer to Figure 1 , Figure 2 and Figure 3 The spreading mechanism 010 of this embodiment includes a feeding assembly 100, an auger 200, a first motor 210, a diverter 300 and a spinner assembly 400. The feeding assembly 100 is provided with a material chamber 121, and a feeding port 112 and a discharging port 123 connected to the material chamber 121. The feeding port of the material box is connected to the feeding port 112, and the material stored in the material box can enter the material chamber 121 through the feeding port and the feeding port 112 in sequence; the auger 200 is arranged in the material chamber 121; the first motor 210 and the auger 200 are connected to each other. The transmission connection is used to drive the auger 200 to rotate around its own axis and output the material in the material chamber 121 from the discharge port 123; the diverter 300 is connected to the feeding assembly 100 and is located at the discharge port 123, and the spinner assembly 400 is connected to the feeding assembly 100; wherein, the spinner assembly 400 includes two spinners 410, and the diverter 300 is used to guide the material output from the discharge port 123 to flow to the two spinners 410, that is, the two spinners 410 can be used to spread the material at the same time, thereby improving the efficiency of material spreading.

[0055] It should be understood that in other embodiments, the spinner assembly 400 may also be connected to the diverter 300, which is not specifically limited herein.

[0056] The spreading mechanism 010 of this embodiment can use a set of feeding components 100, auger 200 and first motor 210 to transport materials to the disc assembly 400 including at least two discs 410, through the arrangement of the diverter 300, so that the number of feeding components 100, auger 200 and first motor 210 can be reduced, which can not only reduce the overall volume of the spreading mechanism 010, but also reduce the cost of the spreading mechanism 010. In addition, since the investment in the parts of the spreading mechanism 010 is reduced, the overall weight of the spreading mechanism 010 can be reduced, thereby reducing the load of the unmanned equipment body.

[0057] Of course, in other embodiments, the spreading mechanism 010 may not include the diverter 300, and the two spinners 410 are relatively distributed with respect to the same discharge port 123, so that the material output from the discharge port 123 can fall on the two spinners 410, so that the two spinners 410 can receive and spread the material output from the same discharge port 123, that is, a set of feeding components 100, auger 200 and first motor 210 can be used to transport the material to the spinner assembly 400, so as to reduce the number of feeding components 100, auger 200 and first motor 210, which can not only reduce the overall volume of the spreading mechanism 010, but also reduce the cost of the spreading mechanism 010.

[0058] It should be noted that the structure of the spinning disc 410 is similar to the related art, and includes a disc body 411 and a paddle 412 connected to the disc body 411. When the disc body 411 rotates around its own rotation axis, it can synchronously drive the paddle 412 to move, and use the paddle 412 to beat the material so that the material is spread out.

[0059] The structure of the feeding assembly 100 can be set according to the exemplary embodiment. Figure 4 The feeding assembly 100 includes a feeding frame 110 and a barrel 120. The feeding frame 110 is connected to the material box, and the barrel 120 is connected to the feeding frame 110. The barrel 120 is provided with a material cavity 121, a feed port 122 and a discharge port 123. The feed port 122 and the discharge port 123 are both connected to the material cavity 121. The feeding frame 110 has a hopper 111. The hopper 111 is provided with a feeding port 112, and the feeding port 112 is relatively distributed and connected to the feeding port 122. With such a configuration, the material stored in the material box can enter the hopper 111 from the lower feeding port and the upper feeding port 112 in turn, and enter the material cavity 121 through the feeding port 122. The configuration of the hopper 111 can improve the problem that the material output from the lower feeding port accidentally falls out of the spreading mechanism 010, thereby ensuring the reliability of material transportation.

[0060] Optionally, the feed port 122 is arranged on the outer peripheral side of the barrel 120 and is arranged upward; such a setting makes it easy for the material in the material box to enter the material cavity 121 under the action of its own weight, so as to reduce the setting of the conveying components, which not only reduces the number of parts and reduces costs, but also reduces the overall weight of the spreading device, so as to reduce the load on the unmanned equipment body.

[0061] Optionally, the first motor 210 is connected to the loading frame 110, and the output shaft of the first motor 210 extends into the material cavity 121 to be transmission-connected to the auger 200; specifically, the loading frame 110 further includes a connecting piece 113 connected to the hopper 111, the first motor 210 is connected to the connecting piece 113, and the output shaft of the first motor 210 extends into the material cavity 121 through the connecting piece 113 to be transmission-connected to the auger 200. The way in which the first motor 210 is connected to the connecting piece 113 includes but is not limited to connecting with fasteners such as bolts and clamping.

[0062] Of course, in other embodiments, the first motor 210 may also be connected to the barrel 120 , which is not specifically limited here.

[0063] The connection method between the barrel 120 and the loading frame 110 includes but is not limited to plugging the barrel 120 and the connecting member 113, and connecting with fasteners such as bolts. The connection method between the loading frame 110 and the material box includes but is not limited to connecting the hopper 111 and the material box with fasteners such as bolts or clamping.

[0064] Optionally, the spreading mechanism 010 further includes a first end cover 510, through which the flow divider 300 and the disk assembly 400 are connected to the feeding assembly 100; wherein the first end cover 510 is connected to the barrel 120, and the flow divider 300 and the disk assembly 400 are both connected to the barrel 120 through the first end cover 510. The first end cover 510 is connected to the barrel 120 by, but not limited to, fasteners such as bolts and welding.

[0065] Of course, in other embodiments, the first end cover 510 may also be connected to the hopper 111, which is not specifically limited here.

[0066] For further information, please refer to Figure 4 and Figure 5 The spreading mechanism 010 also includes a top cover 520, which is connected to the first end cover 510 at an angle, and a spreading space 521 is formed between the top cover 520 and the first end cover 510. The diverter 300 and the spinner 410 are both located in the spreading space 521, that is, the diverter 300 and the spinner 410 are both located below the top cover 520. With this arrangement, when the spinner 410 is used to spread the material, the top cover 520 can prevent the material spread by the spinner 410 from flying upward, thereby ensuring the reliability and efficiency of material spreading.

[0067] The angle between the top cover 520 and the first end cover 510 includes but is not limited to 90°, 80°, and 100°; the connection method between the top cover 520 and the first end cover 510 includes but is not limited to integral molding, welding, and connection with fasteners such as bolts.

[0068] Optionally, one end of the axis of the auger 200 is connected to the output shaft of the first motor 210 in a transmission manner, and the connection method includes but is not limited to spline fit, interference fit, and welding; the other end of the axis of the auger 200 is rotatably plugged with the first end cover 510. Such an arrangement can ensure the reliability and stability of the auger 200 being rotatably arranged in the material chamber 121, thereby ensuring the reliability and stability of the material discharge using the auger 200.

[0069] Please refer to Figure 4 and Figure 6 The flow divider 300 of this embodiment includes an inlet 301 and two outlets 302. The inlet 301 is opposite to and connected to the discharge port 123. The two outlets 302 are distributed one-to-one with the two spinners 410. With such a configuration, when a group of auger 200 and the first motor 210 drive the material in the material chamber 121 to be transported from the discharge port 123 to the flow divider 300, the material entering the flow divider 300 can be output from the two outlets 302 to the corresponding spinners 410, so as to ensure that the two spinners 410 can spread the material, thereby saving the number of auger 200 and the first motor 210 and ensuring the reliability of material spreading.

[0070] Furthermore, the flow divider 300 is provided with two flow channels 303, both of which are connected to the inlet 301, and the two flow channels 303 are connected to the two outlets 302 in a one-to-one correspondence, and the material diversion directions of two adjacent flow channels 303 are distributed at an angle α. Such a configuration can ensure that the flow divider 300 can reliably guide the material to the two spinning discs 410, thereby ensuring the reliability of using the two spinning discs 410 to spread the material at the same time.

[0071] The angle α between the material flow directions of the two flow channels 303 can be set as needed, for example, 30°, 60°, 90°, etc., which is not specifically limited here.

[0072] Optionally, the center line of the flow channel 303 intersects with the rotation axis b of the spinner 410; such an arrangement can ensure that the material output from the diverter 300 can reliably fall on the corresponding spinner 410, reduce the amount of material that falls directly without being spread by the spinner 410, and ensure the reliability of material spreading.

[0073] Optionally, see Figure 3 The material flow direction of the flow channel 303 is distributed at an angle β to the rotation axis a of the auger 200, and the rotation axis b of the spinner 410 is located below the rotation axis a of the auger 200. In this way, the material flow direction of the flow channel 303 extends obliquely downward, so that the material entering the diverter 300 can be transported from the outlet 302 to the spinner 410 under the action of its own weight, ensuring the reliability of material transportation.

[0074] Furthermore, the angle β formed between the material flow direction of the flow channel 303 and the rotation axis of the auger 200 can be 30°, 45°, 60°, etc., which is not specifically limited here.

[0075] Optionally, the diameter of the inlet 301 of the diverter 300 is larger than the diameter of the outlet 302 ; such a configuration can improve the phenomenon of blockage when the material is output from the discharge port 123 and enters the diverter 300 .

[0076] The specific structure of the diverter 300 can be set as needed. For example, please refer to Figure 6 In this embodiment, the flow divider 300 includes two arc-shaped guide plates 310, and the two guide plates 310 are connected to each other. One side of the arc concave surface of the guide plate 310 forms a flow channel 303. One end of the two guide plates 310 jointly forms an inlet 301, and the other end of the two guide plates 310 is a respective outlet 302. The connection of the two guide plates 310 is distributed near the inlet 301 and forms a partition. The material entering the flow divider 300 can enter the two flow channels 303 respectively under the action of the partition, and flow through the two flow channels 303 and are respectively output from the corresponding outlets 302. Through the guiding effect of the guide plate 310, the problem that part of the material output from the discharge port 123 directly falls under the action of its own weight and cannot be transported to the spinner 410 can also be improved. The connection method of the two guide plates 310 includes but is not limited to integral molding, welding, and connection with fasteners such as bolts.

[0077] For example, please refer to Figure 7 and Figure 8 In other embodiments, the diverter 300 includes a first flow guide tube 321 and two second flow guide tubes 322, the two second flow guide tubes 322 are connected to the first flow guide tube 321, the first flow guide tube 321 has an inlet 301 at one end away from the second flow guide tube 322, and the two second flow guide tubes 322 have outlets 302 at one end away from the first flow guide tube 321; each second flow guide tube 322 has a flow channel 303, and the two second flow guide tubes 322 are connected to each other, and the connection between the two second flow guide tubes 322 forms a partition and is distributed close to the first flow guide tube 321. The material entering the first flow guide tube 321 can enter the two flow channels 303 respectively under the action of the partition, and flow through the two flow channels 303 and are output from the corresponding outlets 302 respectively; through the diversion effect of the second flow guide tube 322, the problem that part of the material output from the discharge port 123 directly falls due to its own weight and cannot be transported to the spinner 410 can also be improved. The connection method between the first flow guide tube 321 and the two second flow guide tubes 322 , and the connection method between the two second flow guide tubes 322 include but are not limited to integral molding, welding, and connection with fasteners such as bolts.

[0078] It should be understood that in other embodiments, the flow splitter 300 includes an inlet 301 and an outlet 302 connected thereto, and the flow splitter 300 further has a flow channel 303 connected between the inlet 301 and the outlet 302, the caliber of the outlet 302 is larger than the caliber of the inlet 301, and the inner diameter of the flow channel 303 gradually increases from the inlet 301 to the outlet 302, so that the flow splitter 300 is roughly trumpet-shaped, wherein the outlet 302 and the two spinners 410 are relatively distributed at the same time. Such an arrangement can also make the material entering the flow splitter 300 gradually dispersed during the process of being transported from the inlet 301 to the outlet 302, thereby ensuring that the material can be transported from the outlet 302 to the two spinners 410.

[0079] In order to further reduce the number of motors used in the spreading mechanism 010; please refer to Figure 4 The spreading mechanism 010 of this embodiment further includes a second motor 420 and a transmission assembly 430. The second motor 420 is connected to the two spinning discs 410 through the transmission assembly 430. Specifically, the second motor 420 is connected to the disc bodies 411 of the two spinning discs 410 through the transmission assembly 430. The second motor 420 drives the two disc bodies 411 to rotate around their own axes through the transmission assembly 430, and drives the paddle 412 to move and poke the material. With such a configuration, the two spinning discs 410 can be driven to rotate by only one second motor 420, which reduces the number of second motors 420, helps to further reduce the overall volume of the spreading mechanism 010, and helps to reduce costs.

[0080] The structure of the transmission assembly 430 can be selected as needed; in this embodiment, the transmission assembly 430 includes two mutually meshing gears 431, the two gears 431 are transmission-connected to the two spinning discs 410 in a one-to-one correspondence, and the second motor 420 is transmission-connected to one of the gears 431. In this arrangement, the two gears 431 can be driven to rotate synchronously by one second motor 420, and the rotation directions of the two gears 431 are opposite, and the two gears 431 can be used to synchronously drive the two spinning discs 410 to rotate in two opposite directions, so that the two spinning discs 410 can be used to reliably spread the materials.

[0081] Alternatively, if Figure 2 As shown, the left one of the two gears 431 is configured to rotate clockwise, and the other gear 431 is correspondingly configured to rotate counterclockwise; in this way, it can be ensured that the two spinners 410 driven by the two gears 431 have a spreading effect of throwing the material downward and to both sides, thereby ensuring the reliability of material spreading.

[0082] Further, the radius of the gear 431 is greater than the radius of the disk body 411 of the spinning disk 410. Such a configuration can ensure that there is a certain gap between the two spinning disks 410 to improve the problem of mutual interference when the two spinning disks 410 rotate, and ensure the reliability of the two spinning disks 410 in spreading materials.

[0083] It should be understood that in other embodiments, the transmission assembly 430 may further include a transition gear, and the two gears 431 may further be connected by a transition gear transmission, which is not specifically limited herein. In the embodiment where the two gears 431 are connected by a transition gear transmission, the sum of the radius of the gear 431 and the radius of the transition gear may be configured to be larger than the radius of the spinner 410, thereby improving the problem of interference between the spinners 410.

[0084] Alternatively, in other embodiments, the spreading mechanism 010 includes two second motors 420 , and the two second motors 420 are transmission-connected to the disc bodies 411 of the two spinning discs 410 in a one-to-one correspondence.

[0086] Please refer to Figure 4 and Figure 5 The spreading mechanism 010 of this embodiment also includes a shielding member 440, which is arranged between the transmission assembly 430 and the spinner 410 to block the material from flowing toward the transmission assembly 430, that is, the shielding member 440 is arranged between the multiple gears 431 and the multiple spinners 410 to block the material from flowing toward the gears 431, thereby preventing the material from entering between the gears 431 and causing jamming.

[0087] Optionally, the spreading mechanism 010 also includes a second end cover 450, the shielding member 440 has a accommodating chamber 441, the gear 431 is rotatably arranged in the accommodating chamber 441, and the rotating shaft of the gear 431 can pass through the shielding member 440 and be transmission-connected to the spinning disc 410, or the rotating shaft of the spinning disc 410 can pass through the shielding member 440 to enter the accommodating chamber 441 and be rotationally connected to the gear 431; the second end cover 450 is connected to the side of the shielding member 440 away from the spinning disc 410, and is blocked at the opening of the accommodating chamber 441; the second motor 420 is connected to the side of the second end cover 450 away from the accommodating chamber 441, and the driving shaft of the second motor 420 passes through the second end cover 450 and is transmission-connected to one of the gears 431, or the rotating shaft of one of the gears 431 passes through the second end cover 450 and is transmission-connected to the second motor 420. With such an arrangement, the gear 431 can be protected between the shielding member 440 and the second end cover 450 , thereby alleviating the problem of impurities being stuck between the gears 431 and causing obstruction.

[0088] The connection method between the second motor 420 and the second end cover 450 includes, but is not limited to, connection with fasteners such as bolts, clamping, and bonding.

[0089] Furthermore, the second end cover 450 and the shielding member 440 are simultaneously connected to the first end cover 510, so that the spinning plate 410 is connected to the feeding assembly 100 through the second end cover 450, the shielding member 440 and the first end cover 510. The second end cover 450 and the shielding member 440 are connected to the first end cover 510 by bolts; of course, in other embodiments, the second end cover 450 can also be welded to the shielding member 440, and the shielding member 440 can also be welded to the first end cover 510, which is not specifically limited here.

In this arrangement, at least two disks 410 can be driven by a second motor 420 to reduce the number of second motors 420, which can not only reduce the overall volume of the spreading mechanism 010, but also reduce the cost.

[0091] The working process of the drone of this embodiment when used for spreading materials includes: transporting the materials in the material box to the material chamber 121 of the loading assembly 100, using the first motor 210 to drive the auger 200 to rotate, so that the materials in the material chamber 121 are discharged from the material chamber 121 through the discharge port 123 and enter the diverter 300, and under the guidance of the diverter 300, the materials flow to the two spinners 410 respectively, and the second motor 420 is used to drive the two spinners 410 to rotate, so that the materials can be spread out.

[0092] In summary, the spreading mechanism 010 or the spreading device of the utility model can be used for unmanned equipment, and the volume of the spreading mechanism 010 can be reduced, and the number of components invested can be reduced to reduce costs; moreover, since the investment in components of the spreading mechanism 010 or the spreading device is reduced, the overall weight of the spreading mechanism 010 or the spreading device can be reduced, thereby reducing the load on the unmanned equipment body.
