The sowing mechanism 10 and the controller are both arranged on a movable carrier, and the movable carrier can drive the sowing mechanism 10 and the controller to move in the moving process. The controller is electrically connected with the mobile carrier, so that the mobile carrier can be controlled by the controller to move according to the set route.

The storage mechanism is used for storing materials, so that the moving carrier can carry a specified amount of materials in the moving process, and the sowing mechanism 10 is connected to the storage mechanism, so that the sowing mechanism 10 can obtain the materials from the storage mechanism, and the sowing mechanism 10 can conveniently perform sowing of the materials.

In prior art, unmanned aerial vehicle's the whole two parts of controlling that divide into of system of scattering usually, drive for two parts homoenergetic effectively, need drop into two at least driven structures, and based on this, because need consider that unmanned aerial vehicle is holistic to occupy volume and quality even, the position that just causes the system of scattering arranges the degree of difficulty great, very big improvement unmanned aerial vehicle's cost.

In order to improve the above technical problem, in other words, to improve the layout of the drone, thereby facilitating the placement of the seeding system, and also reducing the cost of the drone, the feeding mechanism 11 and the seeding mechanism 10 in the embodiment of the present application are provided.

Referring to fig. 1, in some embodiments of the present application, a spreader mechanism 10 includes a feed mechanism 11 and a spreader 12. The feeding mechanism 11 is connected to the storage mechanism, and the feeding mechanism 11 can obtain the material from the storage mechanism and can also be used for conveying the material. The spreader 12 is connected to the feeding mechanism 11, and the spreader 12 can take the material from the feeding mechanism 11 and spread the material to a designated position, thereby completing the spreading work. It should be noted that the feeding mechanism 11 and the sowing mechanism 10 are both electrically connected with the controller; the controller can control the feeding mechanism 11 to convey the materials so as to control the feeding amount, the feeding rate, the feeding time and the like of the feeding mechanism 11; the controller may control the spreader 12 to spread the material to control the amount, rate, time, and location of the spreader 12.

It should be noted that during the operation of the scattering operation, the controller may control the operation of the feeding mechanism 11 so that the feeding mechanism 11 can convey the material obtained from the storage mechanism towards the scattering mechanism 10. After the spreading mechanism 10 receives the material conveyed by the feeding mechanism 11, under the control of the controller, the spreading mechanism 10 can spread the material to a specified position, thereby completing the spreading operation specified by the user.

Referring to fig. 4 and 5, the feeding mechanism 11 includes a driving structure 100 and two spiral conveying structures 200. The two spiral conveying structures 200 are in transmission connection with the driving structure 100, in other words, the driving structure 100 can simultaneously drive the two spiral conveying structures 200 to operate, so that the two spiral conveying structures 200 can simultaneously convey materials. By having one drive structure 100 simultaneously drive two auger structures 200, the number of drive structures 100 may be reduced, thereby reducing the overall weight of the sowing mechanism 10 and, at the same time, reducing the overall cost of the sowing mechanism 10. In addition, the two conveying screws 200 are spaced apart. Moreover, the two spiral conveying structures 200 are arranged in parallel, and the conveying directions of the two spiral conveying structures 200 are parallel.

In other words, the two spiral conveying structures 200 are arranged independently, so that the materials conveyed by the two spiral conveying member structures 200 do not interfere with each other in the material conveying process of the two spiral conveying structures 200, and the distribution of the materials can be facilitated.

As described above, in the feeding mechanism 11, the two spiral conveying structures 200 are both in transmission connection with the driving structure 100, and one driving structure 100 can drive the two spiral conveying structures 200 at the same time, so that the two spiral conveying structures 200 can simultaneously convey materials, thereby reducing the number of the driving structures 100 and reducing the cost. Based on this, by arranging the two spiral conveying structures 200 in parallel and making the conveying directions of the two spiral conveying structures 200 parallel, the arrangement positions of the two spiral conveying structures 200 relative to the driving structure 100 can be made symmetrical, and the arrangement of the spiral conveying structures 200 can be facilitated without affecting the uniform distribution of the overall quality of the sowing mechanism 10. Therefore, the feeding mechanism 11 can improve the layout of the sowing mechanism 10, thereby facilitating the installation and assembly of the whole sowing mechanism 10 and achieving the purpose of reducing the cost.

It is worth to be noted that, because the two spiral conveying structures 200 are arranged in parallel, and the conveying directions of the two spiral conveying structures 200 are the same, the two spiral conveying structures 200 are arranged substantially symmetrically, so that the two spiral conveying structures 200 are arranged on the moving carrier conveniently, the position arrangement of the two spiral conveying structures 200 is facilitated, and meanwhile, the quality uniformity of the moving carrier is ensured conveniently, and therefore, the moving stability of the moving carrier is improved.

Referring to fig. 2, in some embodiments of the present application, the driving structure 100 includes a transmission body 120 and a driving body 110, wherein the driving body 110 is used for outputting power, and the transmission body 120 is used for transmitting the power output by the driving body 110, in other words, the driving body 110 is in transmission connection with the transmission body 120 so as to output power through the transmission body 120. In addition, the transmission body 120 can provide a load bearing function to the driving body 110. The two spiral conveying structures 200 are connected to the transmission main body 120 and are in transmission connection with the transmission main body 120, and based on this, the transmission main body 120 can transmit the power output by the driving main body 110 to the two spiral conveying structures 200, so that the two spiral conveying structures 200 convey the material. At the same time, the transmission body 120 may also provide a bearing function to the conveying screws 200 to ensure stability of the two conveying screws 200.

Wherein, in order to ensure the overall stability of the driving structure 100, the driving body 110 corresponds to between the two conveying screw structures 200; wherein, through corresponding the driving main body 11 between the two spiral conveying structures 200, the two spiral conveying structures 200 can be symmetrically arranged on two sides of the driving main body 110, thereby ensuring that the two spiral conveying structures 200 are uniformly distributed on the driving structure 100, and simultaneously avoiding the quality uniformity of the driving structure influenced by the arrangement position of the driving main body 110. Moreover, since the driving body 110 is disposed between the two spiral conveying structures 200, the two spiral conveying structures 200 can be symmetrically disposed on two sides of the driving body 110, thereby improving the overall stability of the driving structure 100.

It should be noted that, the driving body 110 corresponding to the space between the two spiral conveying structures 200 can be represented as: the driving body 110 is disposed between the two conveying screws 200, in other words, the driving body 110 is located at a midpoint of a line connecting the two conveying screws 200; alternatively, the driving body 110 is positioned below the two screw conveyors 200, and the installation position of the driving body 110 is positioned on the perpendicular bisector of the line connecting the two screw conveyors 200.

In some embodiments of the present application, the drive body 110 may be coupled to the transmission body 120 to enable coupling of the drive body 110; thereby, stability of the driving body 110 is ensured by the transmission body 120 providing a load bearing effect to the driving body 110.

In addition, referring to fig. 3, in order to provide a protection effect to the driving body 110, in other embodiments of the present application, a mounting cavity 231 may be disposed between the spiral conveying structures 200, and the driving body 110 is mounted inside the mounting cavity 231. Moreover, the feeding mechanism 11 may further include a cover plate 230, and the cover plate 230 covers the mounting cavity 231 to cover the driving body 110, so that a sealed space for mounting the driving body 110 may be formed by the cover plate 230 and the mounting cavity 231, and thus the cover plate 230 and the two spiral conveying structures 200 forming the side walls of the mounting cavity 231 provide protection for the driving body 110. The cover plate 230 can be detachably connected to the two spiral conveying structures 200 by screws or buckles, so as to cover the driving main body 110, and the cover plate 230 can be conveniently detached to facilitate maintenance of the driving main body 110.

Alternatively, in other embodiments of the present application, a seat 300 for bearing the driving body 110 may also be disposed between the spiral conveying structures 200, and the seat 300 forms the mounting cavity 231 thereon; the cover plate 230 may be detachably connected to the housing 300 to cover the mounting cavity 231, thereby covering the driving body 110. In the case of disposing the seat 300, the seat 300 may be integrally formed with the spiral conveying structure 200; alternatively, the seat 300 may be connected to the spiral conveying structure 200 by clamping, welding, bonding, or screwing. It should be noted that the seat 300 is not only connected to the screw conveying structure 200, but also connected to the transmission body 120 to provide sufficient bearing function for the driving body 110 in order to ensure the stability of bearing the driving body 110. Of course, the seat 300 may be eliminated.

In order to improve the heat dissipation effect of the driving body 110, a plurality of heat dissipation holes 232 are formed on the cover plate 230, and the plurality of heat dissipation holes 232 are formed on the cover plate 230 at intervals and penetrate through the cover plate 230. Under the condition that the driving body 110 generates heat during operation, the heat can be generated from the heat dissipation holes 232, so that the driving body 110 can dissipate heat rapidly, and the driving body 110 can work stably.

Optionally, with continued reference to fig. 4 and 5, in some embodiments of the present application, auger structure 200 includes a housing 210 and an auger element 220. A conveying channel 201 is arranged in the shell 210, and a feeding hole 202 communicated with the conveying channel 201 is formed in the shell 210; the conveying screw 220 is rotatably disposed inside the conveying passage 201. Under the condition of being connected with the storage mechanism, the shell 210 is connected with the storage mechanism, and the feed inlet 202 is made to correspond to the discharge hole of the storage mechanism, so that the storage mechanism can receive the material through the feed inlet 202 under the condition of exporting the material, and the material is guided into the conveying channel 201. The two conveying screws 220 are both in transmission connection with the driving structure 100, so that the driving structure 100 can simultaneously drive the two conveying screws 220 to operate, and the conveying members 220 can convey materials in the conveying channel 201. In addition, the two housings 210 are connected to the driving structure 100, which not only can improve the stability of the housing 210 through the connection between the housing 210 and the driving structure 100 to ensure the stability of the conveying screw 220, but also facilitates the transmission connection between the conveying screw 220 and the driving structure 100.

To achieve the parallel arrangement of the two conveying screws 200, in some embodiments of the present application, the two conveying screws 220 are arranged in parallel. It should be noted that, when the conveying screw 220 is driven to rotate by the driving structure 100, the conveying direction of the material by the conveying screw 220 is parallel to the rotation axis of the conveying screw 220, and therefore, when the two conveying screws 220 are parallel to each other, it can be considered that the rotation axes of the two conveying screws 220 are parallel to each other, and thus, the conveying directions of the two conveying screws 220 are parallel to each other, and the purpose that the conveying directions of the two conveying screws 200 are parallel to each other can be achieved.

It should be noted that, in the case where the two conveying screws 220 are parallel to each other, the housing 210 is disposed in such a manner as to substantially follow the extending direction of the conveying screws 220 in order to accommodate the conveying screws 220, and therefore, in the case where the two conveying screws 220 are parallel to each other, the two housings 210 can be made to be substantially parallel. Based on this, it is convenient to arrange the two housings 210 in a symmetrical manner.

Optionally, two housings 210 are spaced apart. Of course, in some embodiments of the present application, the two housings 210 are spaced apart from each other, so that the two screw conveying structures 200 are disposed independently from each other, in other words, the two housings 210 can be assembled or disassembled independently. Because the interval of two casings 210 sets up, can conveniently adjust the distance between two casings 210, in other words, can adjust the distance between the casing 210 according to unmanned aerial vehicle's service environment and drive structure 100's setting mode etc. to make two auger delivery structure 200's setting mode can adapt to current actual demand.

It should be understood that in other embodiments of the present application, the two housings 210 may be connected to form a whole in other manners. For example, a connection frame is provided between the two housings 210, and the connection frame connects the two housings 210 to form a whole. For another example, the two housings 210 are integrally formed, in which case, it is considered that two conveying channels 201 and two feed ports 202 are formed on an integral housing, and thus the conveying screws 220 are disposed in the two conveying channels 201 so that the conveying screws 220 are parallel to each other. Also, the two housings 210 are connected to form a whole by welding, bonding, or magnetic connection, for example. For example, the two housings 210 may be detachably connected to form a whole by providing two housings 210 with matching snaps, respectively.

In addition, in other embodiments of the present application, the connection relationship between the conveying screw 220 and the housing 210 may also be in other manners. For example, referring to fig. 6 and fig. 7 in combination, the spiral conveying structure 200 further includes a mounting shell 240, and a space for the spiral conveying element 220 to rotatably connect is provided inside the mounting shell 240, in other words, the spiral conveying element 220 is rotatably provided inside the mounting shell 240. The mounting case 240 is detachably disposed inside the conveying passage 201, thereby achieving the detachable connection of the conveying screw 220 and the housing 210. It should be noted that, the casing 210 is provided with a feed port 202 communicated with the conveying channel 201, and correspondingly, in order to enable the material to enter the installation casing 240, the installation casing 240 is provided with an inlet corresponding to the feed port 202, and the area of the inlet may be larger than that of the feed port 202, so as to ensure that the material introduced from the feed port 202 can be introduced into the space inside the installation casing 240 from the inlet of the installation casing 240. In addition, in order to facilitate the spiral conveying element 220 to output the material entering the inside of the mounting shell 240, an opening is provided at one end of the mounting shell 240, and the opening is used for guiding the material to the spreader, in other words, the material is output from the opening of the mounting shell 240 by the conveying action provided by the spiral conveying element 220 rotating inside the mounting shell 240, and then enters the spreader through the opening, so that the material can be conveniently spread by the spreader to complete the spreading of the material.

It is worth mentioning that the outer shape of the mounting shell 240 is adapted to the contour formed by the inner peripheral wall of the conveying channel 201, so that the mounting shell 240 can be stably mounted inside the conveying channel 201, and certainly, it is ensured that the inside of the mounting shell 240 has a sufficient space to facilitate and effectively convey the materials.

The housing 210 includes a feed body 211 and a transport body 212. It should be noted that the feeding body 211 is configured to be connected to the storage mechanism, so that the feeding body 211 can receive the material guided out by the storage mechanism. The conveying body 212 is connected to the spreader 12, and the conveying body 212 can convey the material to the spreader 12 to facilitate the receiving and spreading of the material by the spreader 12. In addition, the feeding body 211 is connected to the driving structure 100 to realize the connection of the housing 210 with the driving structure 100.

A feeding channel 2111 is arranged in the feeding main body 211, and the feeding channel 2111 forms a feeding hole 202 at one side of the feeding main body 211; wherein the feeding channel 2111 is an inner space of the feeding body 211, and the feeding channel 2111 further forms the feeding hole 202 at one side of the feeding body 211. Under the condition that the feeding main body 211 is connected with the storage mechanism, the feeding port 202 is communicated with the discharging port of the storage mechanism, so that the material can be received through the feeding port 202, and the material can conveniently enter the feeding channel 2111. To facilitate the conveying of the material by the conveying screw 220, at least a portion of the conveying screw 220 is disposed within the feed channel 2111; thereby allowing the material to be conveyed by the conveying screw 220 with the material entering the interior of the feed passage 2111.

It should be understood that in other embodiments of the present application, the placement of the conveying screw 220 in the feeding channel 2111 may be eliminated, and the material may be brought into contact with the conveying screw 220 in other ways, so that the material is conveyed. For example, an inclined flow guide surface is provided inside the feed channel 2111 to guide the material toward the conveying screw 220; as another example, other moving structures may be provided inside the feed channel 2111 to push the material toward the conveying screw 220, etc.

The conveying body 212 is connected to a side of the feeding body 211 away from the driving structure 100, and a feeding channel 2121 is provided inside the conveying body 212, and the feeding channel 2121 and the feeding channel 2111 are communicated to form a conveying channel 201 together. The two feed channels 2121 are parallel to each other; and at least a portion of the conveying screw 220 is disposed inside the feed passage 2121. Wherein the spreader 12 is connected to the side of the conveying body 212 remote from the feeding body 211, whereby the material can be conveyed to the spreader 12 through the conveying body 212, thereby facilitating the spreading of the material by the spreader 12. It should be noted that, in the case where at least a part of the conveying member 220 is disposed inside the feeding passage 2111, it can be considered that the "at least a part of" the conveying member 220 is disposed inside the feeding passage 2121, and that a part of the conveying member 220 is disposed inside the feeding passage 2121. To ensure that material is efficiently delivered to the spreader 12, the conveying body 212 should be provided with at least part of the auger member 220, thereby ensuring that material entering the interior of the feed channel 2121 is delivered by the auger member 220 to the spreader 12. It should be appreciated that in other embodiments of the present application, since there may be instances where the placement of the auger member 220 in the feed channel 2111 is eliminated, in which case the entire auger member 220 may be placed inside the conveying body 212.

In some embodiments of the present application, the two conveying bodies 212 are parallel to each other, so that the two conveying members 220 respectively disposed inside the two feeding channels 2121 are substantially parallel, so that the conveying directions of the two conveying members 220 are parallel to each other, thereby achieving the purpose of parallel conveying directions of the two conveying structures 200. Thereby achieving an improvement in the layout of the sowing mechanism 10, facilitating the assembly of the sowing mechanism 10 as a whole, and achieving a cost reduction.

In some embodiments of the present application, the feeding body 211 and the conveying body 212 may be detachably connected, and the detachable connection may be a bolt connection, a snap connection, a magnetic connection, or a detachable adhesive connection. Of course, in other embodiments of the present application, the feeding body 211 and the conveying body 212 may be integrally connected to form a whole. The connecting structure can also be connected into a whole by adopting a welding mode or a welding mode, and the like.

It should be understood that in other embodiments of the present application, the conveying body 212 may be eliminated in the case where the conveying screw 220 is provided inside the feeding passage 2111.

In addition, in other embodiments, the feeding body 211 and the conveying body 212 may be disposed in a manner that the feeding body 211 and the conveying body 212 are integrally disposed, the feeding body 211 is divided into an upper portion and a lower portion in a radial direction of the conveying screw 220, the upper portion having the feeding port 202 forms the feeding body 211, and the lower portion having the conveying screw 220 forms the conveying body 212. In this case, it may be that the conveying body 212 is connected with the driving structure 100 to realize the connection of the housing 210 and the driving structure 100.

Wherein, in order to facilitate the feeding of the feeding passage 2111, the feeding passage 2111 is formed to be arranged in the radial direction of the conveying screw 220. After the material enters the feeding channel 2111 from the feeding hole 202, the material can directly fall onto the spiral conveying element 220, so that the material can be ensured to contact the spiral conveying element 220 after being guided into the feeding main body 211, the material can be conveyed, the conveying efficiency of the material can be improved, and the blockage of the material guided out by the storage mechanism can be prevented.

It should be noted that, in some embodiments of the present application, the opening direction of the feeding passage 2111 is substantially perpendicular to the rotation axis of the conveying screw 220, thereby realizing that the feeding passage 2111 is formed along the radial direction of the conveying screw 220. Because the opening direction of the feeding channel 2111 is vertical to the spiral conveying piece 220, the moving distance of the materials in the feeding channel 2111 can be shortened, the time for the materials to move to contact with the spiral conveying piece 220 can be shortened, and the conveying efficiency is improved; meanwhile, the overall volume of the feeding main body 211 can be reduced, so that the overall structure of the feeding mechanism 11 is compact, and the feeding mechanism 11 is convenient to assemble.

Of course, the feed passage 2111 may be arranged differently in other embodiments of the present application. For example, the feed passage 2111 opens in a direction parallel to the axial direction of the conveying screw 220. For example, the opening direction of the feed passage 2111 forms an acute angle with the axial direction of the conveying screw 220.

Optionally, the feed body 211 has a receiving flat 2112 thereon; the feed port 202 is formed on the seating plane 2112; under the condition of being connected with the storage mechanism, the receiving plane 2112 is matched with the storage mechanism, so that the sealing of the feeding hole 202 is conveniently realized, and the leakage of materials is avoided. Of course, the installation stability of the two shells 210 can be ensured, the installation positions of the two shells 210 can be conveniently controlled, and then the two spiral conveying pieces 220 can be conveniently adjusted to be parallel to each other. To facilitate assembly of the two housings 210, in some embodiments of the present application, the receiving flats 2112 on the two feeder bodies 211 are disposed coplanar. In the case where the assembly of the two housings 210 with the storage mechanism is performed, both housings 210 may be mounted on the same side of the storage mechanism, thereby facilitating the assembly of the housings 210. Meanwhile, the distance between the two shells 210 can be reduced conveniently, the arrangement of the two spiral conveying structures 200 is facilitated, and the assembly of the driving structure 100 and the two spiral conveying structures 200 can be facilitated.

It should be understood that in other embodiments of the present application, the two seating surfaces 2112 may be arranged in other ways. For example, two receiving planes 2112 form an included angle. For another example, the two receiving planes 2112 are parallel to each other, and a certain distance is formed between the planes of the two receiving planes 2112.

In addition, in some embodiments of the present application, optionally, the cross-sectional area of the feeding body 211 along the radial direction of the conveying screw 220 is gradually increased, so that the feeding port 202 is flared, thereby facilitating the receiving of the material by the feeding body 211 and facilitating the introduction of the material. Meanwhile, the feeding amount of the materials can be ensured, the conveying efficiency of the materials is improved, and the spreader 12 is ensured to have enough materials for spreading.

In addition, the two feed bodies 211 contact each other on the outer side in the radial direction of the conveying screw 220. In this case, the two feeding bodies 211 can be arranged corresponding to one discharge port on the storage mechanism, so that the two feeding bodies 211 can be fed simultaneously. It should be noted that, the outer sides of the two feeding bodies 211 are in contact with each other, that is, the two feeding bodies 211 do not form a gap on the receiving plane 2112, so that the material guided out from one discharging port can be received by the two feeding ports 202, and the material is prevented from leaking out from between the two feeding bodies 211.

It should be understood that in other embodiments of the present application, a space may be provided between the two feeding bodies 211, and on this basis, the two feeding bodies 211 may be provided corresponding to the two discharge ports on the storage mechanism to ensure effective material transportation. Of course, in other embodiments, in the case that the two housings 210 are integrally formed as a single body, the two feed channels 2111 may communicate to form a single body channel.

In addition, in some embodiments of the present application, to facilitate the material transportation, optionally, the feeding channel 2121 is disposed coaxially with the spiral conveying element 220. Of course, on the basis that the feeding channel 2121 and the spiral conveying element 220 are coaxially arranged, the distance between the circumferential wall surrounding the feeding channel 2121 and the spiral conveying element 220 can be reduced as much as possible, so that when the material enters the feeding channel 2121, the material is prevented from being separated from the spiral conveying element 220 to cause the conveying stagnation of the material, in other words, the material can be effectively conveyed.

It should be understood that in other embodiments of the present application, the feed channel 2121 and the conveying screw 220 may be arranged in other manners. For example, the central axis of the feeding passage 2121 forms a small angle with the central axis of the conveying screw 220, and in this case, the central axis of the feeding passage 2121 and the central axis of the conveying screw 220 are arranged in a collinear manner, in other words, the feeding passage 2121 and the conveying screw 220 are arranged coaxially. For another example, the central axis of the feeding passage 2121 and the central axis of the spiral conveying element 220 may be parallel to each other and have a small distance therebetween, and in this case, the feeding passage 2121 and the spiral conveying element 220 may be considered to be coaxially disposed.

The conveying screw 220 includes a rotating shaft 221 and a conveying portion 222. The rotating shaft 221 is arranged inside the conveying channel 201, and the rotating shaft 221 penetrates through the shell 210 to be in transmission connection with the driving structure 100; so that the rotation shaft 221 is rotated when the driving structure 100 is operated. The conveying section 222 is provided on the rotating shaft 221 along a spiral path; in the case where the driving structure 100 operates, the two rotation shafts 221 may be rotated in synchronization. Wherein, two spiral conveying elements 220 parallel to each other represent: the two rotational axes 221 are parallel.

It should be noted that, in the embodiment of the present application, in the process that the driving structure 100 drives the two rotating shafts 221, the driving shaft provides rotating acting forces to the two rotating shafts 221, and at the same time, the two rotating shafts 221 apply reaction forces to the driving structure 100, and because the two rotating shafts 221 are parallel to each other, the reaction force acting effects applied to the driving structure 100 by the two rotating shafts 221 can be equivalent, so that the vibration of the driving structure 100 can be reduced, the stability of the driving structure 100 is improved, and the stability of material conveying can be improved.

In addition, in order to further improve the stability of the driving structure 100, the rotation directions of the conveying parts 222 on the two rotating shafts 221 may be opposite, and the rotation directions of the two rotating shafts 221 may be opposite when the driving structure 100 is in operation. At this time, it is ensured that the conveying directions of the two spiral conveying elements 220 are parallel and the directions are the same, and the driving structure 100 applies a torsional force to the rotating shaft 221, the rotating shaft 221 applies an opposite torsional force to the driving structure 100, and the rotating directions of the two rotating shafts 221 are opposite, so that the two torsional forces applied to the driving structure 100 can be mutually cancelled, and the stability of the driving structure 100 is ensured.

Based on this, by arranging the two spiral conveying structures 200 in parallel and making the conveying directions of the two spiral conveying structures 200 parallel, the arrangement positions of the two spiral conveying structures 200 relative to the driving structure 100 can be made symmetrical, and the arrangement of the spiral conveying structures 200 can be facilitated without affecting the uniform distribution of the overall quality of the sowing mechanism 10. Therefore, the feeding mechanism 11 can improve the layout of the sowing mechanism 10, thereby facilitating the installation and assembly of the whole sowing mechanism 10 and achieving the purpose of reducing the cost.
