[0002] Well-cellar transplanting is a form of tobacco seedling transplanting, which is generally suitable for tobacco-producing areas with moist and sticky soil. Artificial wells are formed by drilling holes on the ridges, and the tobacco seedlings are placed vertically in the wells and covered with an appropriate amount of soil to create a microenvironment suitable for the growth of tobacco seedlings.

[0003] When the existing transplanter performs well-cellar transplanting, the cellar-making device located at the front first completes the cellar making, and then the seedling-throwing device located at the rear throws the seedlings into the well-made cellar. That is, the cellar making and the seedling-throwing are completed by two independent devices respectively. Such an arrangement results in a relatively complex transmission structure of the transplanter and requires a large layout space, which is difficult to manufacture. Summary of the Invention

They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the embodiments of the present invention; the directional words "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0058] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0059] The present invention first provides a planting device.

[0060] In one embodiment, referring to the attached Figure 1 As shown, the planting device includes:

[0061] Mounting bracket 100;

[0062] The duckbill mechanism 200 includes a cylindrical support 201 and a duckbill 202. The cylindrical support 201 is rotatably connected to the mounting bracket 100 about its own central axis. The duckbill 202 is openably connected to the first end of the cylindrical support 201. The duckbill 202 is connected to the cylindrical support 201 and their central axes are coaxially arranged.

[0063] The transfer case 300 is mounted on the mounting bracket 100 and is respectively coupled with the cylindrical bracket 201 and the duckbill 202 to drive the cylindrical bracket 201 to rotate and the duckbill 202 to open and close. The transfer case 300 is suitable for connection to a power source.

[0064] In the planting device of the present embodiment, it is connected to the power source through the transfer case 300, and the power is transmitted to the cylindrical bracket 201 and the duckbill 202 to realize the opening and closing and rotation of the duckbill 202. In the process of well-cellar transplanting, the duckbill 202 can be closed and the cylindrical bracket 201 can be rotated to drive the duckbill 202 to rotate, thereby realizing cellar digging. When the cellar digging is completed, the duckbill 202 is opened, and the seedlings are delivered to the dug well cellar through the cylindrical bracket 201 and the opened duckbill 202. In this way, the planting device of the embodiment can realize cellar digging and precise seedling delivery, effectively improving the working efficiency. In addition, the structure of the planting device of the present embodiment is relatively simple, and the required layout space is small. In this way, the planting device of the present embodiment is applied to the transplanter, which can effectively simplify the structure of the transfer machine, improve the working efficiency, and reduce the manufacturing difficulty.

[0065] In one embodiment, referring to the attached Figure 4 and attached Figure 5 As shown, the transfer case 300 includes:

[0066] The bracket transmission shaft 301 is in transmission cooperation with the cylindrical bracket 201. The rotation of the bracket transmission shaft 301 can drive the cylindrical bracket 201 to rotate;

[0067] The duckbill transmission shaft 302 cooperates with the duckbill 202 in transmission. The rotation of the duckbill transmission shaft 302 can drive the duckbill 202 to open and close. The rotation speed of the duckbill transmission shaft 302 is lower than the rotation speed of the bracket transmission shaft 301.

[0068] In this embodiment, the rotation speed of the duckbill transmission shaft 302 is lower than the rotation speed of the bracket transmission shaft 301. Such an arrangement can make the frequency of the rotation of the duckbill 202 higher than the frequency of the opening and closing action, thereby realizing continuous cellar digging and intermittent seedling planting.

[0069] In one embodiment, the duckbill drive shaft 302 is configured as a power input shaft for connecting to a power source. The transfer case 300 also includes an intermediate drive shaft. Both the duckbill drive shaft 302 and the intermediate drive shaft, as well as the intermediate drive shaft and the support drive shaft 301, are coupled via gear sets with a transmission ratio of less than 1. This arrangement allows the speed of the duckbill drive shaft 302 to be lower than that of the support drive shaft 301.

[0070] Specifically, one end of the duckbill transmission shaft 302 is provided with a connection port for accessing the output end of the power source, wherein the power source is not limited in form and can be a motor, a flexible shaft, etc.

[0071] Specifically, the intermediate transmission shaft includes a first intermediate transmission shaft 306 and a second intermediate transmission shaft 307. The first intermediate transmission shaft 306 is arranged between the bracket transmission shaft 301 and the duckbill transmission shaft 302. The second intermediate transmission shaft 307 is arranged between the bracket transmission shaft 301 and the first intermediate transmission shaft 306. A third bevel gear 308 is fixedly provided on the duckbill transmission shaft 302. A fourth bevel gear 309 is fixedly provided on the first intermediate transmission shaft 306. The third bevel gear 308 and the fourth bevel gear 309 are meshed. A first spur gear 308 is fixedly provided on the first intermediate transmission shaft 306. 310, a second spur gear 311 is fixedly provided on the second intermediate transmission shaft 307, the first spur gear 310 and the second spur gear 311 are meshed, a fifth bevel gear 312 is fixedly provided on the second intermediate transmission shaft 307, a sixth bevel gear 313 is fixedly provided on the bracket transmission shaft 301, the fifth bevel gear 312 and the sixth bevel gear 313 are meshed, wherein the transmission ratio of the third bevel gear 308 and the fourth bevel gear 309, the transmission ratio of the first spur gear 310 and the second spur gear 311, and the transmission ratio of the fifth bevel gear 312 and the sixth bevel gear 313 are all less than 1.

[0072] Specifically, the transfer case 300 includes a case body 314 , the first intermediate transmission shaft 306 and the second intermediate transmission shaft 307 can be connected to the case body 314 via a bidirectional thrust ball bearing, and the bracket transmission shaft 301 and the duckbill transmission shaft 302 can be connected to the case body 314 via a thrust roller bearing.

[0073] Of course, in some other embodiments, both the bracket transmission shaft 301 and the intermediate transmission shaft can be used as power input shafts to achieve different power layouts to adapt to actual installation locations.

[0074] In one embodiment, referring to the attached Figure 3 To the attached Figure 5 As shown, a first bevel gear 303 is fixedly mounted on the bracket transmission shaft 301, and a second bevel gear 203 is fixedly mounted on the cylindrical bracket 201. The first bevel gear 303 is meshed with the second bevel gear 203. In this manner, the rotation of the bracket transmission shaft 301 can drive the cylindrical bracket 201 to rotate.

[0075] In one embodiment, referring to the attached Figure 2As shown, the mounting bracket 100 is provided with a first mounting hole and a second mounting hole that are spaced apart and aligned with each other, the edge of the first mounting hole is formed with a first annular flange 101 that extends inwardly and obliquely in a direction away from the second mounting hole, and the edge of the second mounting hole is formed with a second annular flange 102 that extends inwardly and obliquely in a direction close to the first mounting hole, the cylindrical bracket 201 passes through the first mounting hole and the second mounting hole in sequence and the portion of the outer peripheral wall located between the first mounting hole and the second mounting hole is provided with a plurality of first limiting members 204 and a plurality of second limiting members 205, the plurality of first limiting members 204 are arranged at intervals along the circumference of the cylindrical bracket 201 and respectively abut against the first annular flange 101, and the plurality of second limiting members 205 are arranged at intervals along the circumference of the cylindrical bracket 201 and respectively abut against the second annular flange 102.

[0076] It can be understood that by the limiting cooperation of the first annular flange 101 and the second annular flange 102 with the first limiting member 204 and the second limiting member 205 respectively, the cylindrical bracket 201 can be reliably limited on the mounting bracket 100, so that the cylindrical bracket 201 can be rotatably connected to the mounting bracket 100 around its own central axis.

[0077] In actual use, the first annular flange 101 can limit the upward movement of the duckbill mechanism 200 when the duckbill 202 is in contact with the ground, while the second annular flange 102 provides support for the duckbill mechanism 200 when the duckbill 202 is not in contact with the ground. Furthermore, because both the first annular flange 101 and the second annular flange 102 extend inwardly, the rotation axis of the duckbill mechanism 200 can be kept stable, preventing it from wobbling during movement.

[0078] Specifically, the mounting bracket 100 includes a first mounting plate 106 and a second mounting plate 107 that are spaced apart and opposite to each other. The first mounting plate 106 is provided with a first mounting hole, and the second mounting plate 107 is provided with a second mounting hole. The edges of the first mounting plate 106 and the second mounting plate 107 are fixedly connected by a plurality of connecting members 108. The transfer case 300 can be fixedly connected to the connecting member 108 through a connecting arm 315 so as to be set on the mounting bracket 100.

[0079] In one embodiment, referring to the attached Figure 2 As shown, the first and second limiting members 204, 205 are both rollers, and their wheel surfaces respectively abut against the first and second annular flanges 101, 102. This arrangement allows the first and second limiting members 204, 205 to roll with the first and second annular flanges 101, 102, respectively, further improving the reliability of the limiting mechanism. This reduces friction between the cylindrical bracket 201 and the mounting bracket 100 during rotation, improving the smoothness of the cylindrical bracket 201's rotation and extending the service life of the planting device.

[0080] Specifically, a connecting flange may be protruded from the outer peripheral wall of the cylindrical bracket 201 , and the first limiting member 204 and the second limiting member 205 may be rotatably connected to the connecting flange.

[0081] In one embodiment, referring to the attached Figure 3 , Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 8 And attached Figure 9 As shown, the duckbill mechanism 200 further includes:

[0082] The opening and closing arm assembly includes two connecting shafts 206, two driving arms 207, and an elastic member 208. The two connecting shafts 206 are arranged side by side and are respectively rotatably connected around their own central axes to the connecting flanges provided on the outer edge of the first end of the cylindrical bracket 201. The central axes of the two connecting shafts 206 are arranged perpendicular to the central axis of the cylindrical bracket 201. The first ends of the two driving arms 207 are respectively fixedly connected to the connecting shafts 206, and the second ends respectively extend away from the outer peripheral side of the duckbill 202. An elastic member 208 is connected between the two driving arms 207. The two duckbill pieces of the duckbill 202 are respectively fixedly connected to the two connecting shafts 206.

[0083] The transmission frame 209 is movably connected to the mounting bracket 100 and is movably mounted on the outer peripheral side of the duckbill 202 along the axial direction of the duckbill 202. The transmission frame 209 is in transmission cooperation with the duckbill transmission shaft 302 so that it can move toward the direction close to the cylindrical bracket 201 to the second end of the pressing driving arm 207 under the drive of the duckbill transmission shaft 302.

[0084] It can be understood that when the transmission frame 209 moves toward the direction close to the cylindrical bracket 201 to the second end of the driving arm 207 driven by the duckbill transmission shaft 302, the two driving arms 207 in the opening and closing arm assembly are squeezed and overcome the elastic force of the elastic member 208 to swing back to back, and the two duckbill pieces of the duckbill 202 can be synchronously driven to swing back to back through the two connecting shafts 206, thereby realizing the opening of the duckbill 202. When the transmission frame 209 and the duckbill transmission shaft 302 are disconnected from the transmission, the transmission frame 209 removes the pressing force on the second end of the driving arm 207, allowing the two driving arms 207 in the opening and closing arm assembly to swing toward each other under the elastic force of the elastic member 208, and the two duckbill pieces of the duckbill 202 can be synchronously driven to swing toward each other through the two connecting shafts 206, thereby realizing the closing of the duckbill 202.

[0085] Specifically, the elastic member 208 may be a tension spring.

[0086] Specifically, the duckbill mechanism 200 may include two groups of opening and closing arm assemblies, and the two groups of opening and closing arm assemblies are respectively arranged on opposite sides of the duckbill 202.

[0087] Specifically, a roller is provided at the second end of the driving arm 207 .

[0088] In one embodiment, referring to the attached Figure 3 To the attached Figure 9 As shown, the duckbill transmission shaft 302 is coaxially fixed with a transmission disk 304, the edge of the transmission disk 304 is connected to a toggle rod 305, and the transmission frame 209 is connected to a drive rod 210. The drive rod 210 is arranged on the rotation path of the toggle rod 305 so that it can drive the transmission frame 209 to move toward the direction close to the cylindrical bracket 201 to the second end of the pressure drive arm 207 under the toggle of the toggle rod 305.

[0089] When the toggle rod 305 contacts the driving rod 210, the driving rod 210 will be toggled to drive the transmission frame 209 to move upward to press the driving arm 207. When the toggle rod 305 is disengaged from the driving rod 210, the transmission frame 209 can fall back under the action of its own gravity, thus completing an opening action of the duckbill 202. That is, the transmission disc 304 rotates one circle, and the duckbill 202 opens and closes once. In the rotation of the transmission disc 304, only a small part of the stroke is used to drive the duckbill 202 to open, and the duckbill 202 is in the state of being opened for most of the other strokes. In the closed state, and because the rotation speed of the duckbill transmission shaft 302 is lower than the rotation speed of the bracket transmission shaft 301, the duckbill 202 can be driven to rotate multiple circles during the process of the transmission disk 304 rotating one circle to realize digging the cellar. In this way, the duckbill 202 can be continuously rotated and intermittently opened. By changing the rotation speed of the duckbill transmission shaft 302 and the rotation speed of the bracket transmission shaft 301, or changing the matching relationship between the toggle rod 305 and the drive rod 210 (that is, changing the contact stroke size of the toggle rod 305 and the drive rod 210 during one rotation of the transmission disk 304), the planting device can dig the cellar and plant seedlings according to the preset rhythm, thereby greatly improving the working efficiency.

[0090] In one embodiment, referring to the attached Figure 2 As shown, the mounting bracket 100 is provided with a guide rod 103 extending along the axial direction of the duckbill 202, a sliding sleeve 104 is provided on the guide rod 103, and a transmission frame 209 is fixedly connected to the sliding sleeve 104. Such an arrangement enables the transmission frame 209 to move back and forth along the axial direction of the duckbill 202.

[0091] In one embodiment, referring to the attached Figure 1 and attached Figure 2 As shown, the planting device further includes a seedling receiving tube 400 , which is connected to the mounting bracket 100 and communicates with the second end of the cylindrical bracket 201 .

[0092] The seedling grafting tube 400 serves to extend the seedling grafting height, which can effectively reduce the difficulty of seedling grafting and improve the accuracy of seedling grafting.

[0093] The present invention further provides a transplanter including the aforementioned planting device. The specific structure of the planting device is similar to that of the aforementioned embodiments. Since the present transplanter utilizes all of the technical solutions of all of the aforementioned embodiments, it possesses at least all of the beneficial effects brought about by the technical solutions of the aforementioned embodiments, and therefore, no further details will be given here.

[0094] Specifically, the mounting bracket 100 is provided with a connecting rod for connecting to a connecting rod or a driving member. In the transplanter, the connecting rod connected to the mounting bracket 100 through the connecting rod or the driving member can drive the planting device as a whole to move between the seedling grafting position (tilted downward) and the planting position (vertically downward).
