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 referred device or element must have a specific orientation, be constructed and operated in a specific orientation. 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 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 support 100 around 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 disposed on the mounting bracket 100 and is respectively in transmission cooperation with the cylindrical bracket 201 and the duckbill 202 to drive the cylindrical bracket 201 to rotate and drive the duckbill 202 to open and close. The transfer case 300 is suitable for connecting to a power source.

[0064] In the planting device of the present embodiment, the transfer case 300 is connected to the power source, and the power is transmitted to the cylindrical support 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 support 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 through the cylindrical support 201 and the opened duckbill 202. In this way, the planting device of the embodiment can realize cellar digging and precise seedling delivery, which effectively improves 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 support transmission shaft 301 is in transmission cooperation with the cylindrical support 201, and the rotation of the support transmission shaft 301 can drive the cylindrical support 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 achieving continuous cellar digging and intermittent seedling planting.

[0069] In one embodiment, the duckbill transmission shaft 302 is configured as a power input shaft for connecting to a power source, and the transfer case 300 further includes an intermediate transmission shaft, and the duckbill transmission shaft 302 and the intermediate transmission shaft, as well as the intermediate transmission shaft and the support transmission shaft 301, are both matched through a gear set with a transmission ratio less than 1. In this way, the rotation speed of the duckbill transmission shaft 302 can be less than the rotation speed of the support transmission shaft 301.

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

[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 sleeved on the duckbill transmission shaft 302. A fourth bevel gear 309 is fixedly sleeved on the first intermediate transmission shaft 306. The third bevel gear 308 and the fourth bevel gear 309 are meshed. The first intermediate transmission shaft 306 is fixedly sleeved with a first spur gear 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 support 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 Attachment Figure 5 As shown, the support transmission shaft 301 is fixedly sleeved with a first bevel gear 303, and the cylindrical support 201 is fixedly sleeved with a second bevel gear 203, and the first bevel gear 303 meshes with the second bevel gear 203. In this way, the rotation of the support transmission shaft 301 can drive the cylindrical support 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 which are spaced apart and arranged in opposition, the edge of the first mounting hole is formed with a first annular flange 101 which extends inwardly and obliquely in a direction away from the second mounting hole, the edge of the second mounting hole is formed with a second annular flange 102 which 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 application, the first annular flange 101 can limit the upward movement of the duckbill mechanism 200 when the duckbill 202 touches the soil, and the second annular flange 102 supports the duckbill mechanism 200 when the duckbill 202 does not touch the soil. And because the first annular flange 101 and the second annular flange 102 both extend inwardly, the stability of the rotation axis position of the duckbill mechanism 200 can be maintained to prevent it from swinging 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 relatively arranged. 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 via a connecting arm 315 so as to be arranged on the mounting bracket 100.

[0079] In one embodiment, referring to the attached Figure 2 As shown, the first limiting member 204 and the second limiting member 205 are both rollers and the wheel surfaces are respectively in contact with the first annular flange 101 and the second annular flange 102. In this way, the first limiting member 204 and the second limiting member 205 are respectively in rolling cooperation with the first annular flange 101 and the second annular flange 102, further improving the reliability of the limiting, making the friction between the cylindrical bracket 201 and the mounting bracket 100 smaller during the rotation process, improving the smoothness of the rotation of the cylindrical bracket 201, and also improving 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 Fig. 9 As shown, the duckbill mechanism 200 also 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 rotatably connected to the connecting flanges provided on the outer edge of the first end of the cylindrical bracket 201 around their own central axes. 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 are respectively extended to the outer peripheral side of the duckbill 202 in a reverse direction. 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 cooperates 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 towards 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 cooperation, the transmission frame 209 removes the pressing force on the second end of the driving arm 207, so that the two driving arms 207 in the opening and closing arm assembly can 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 disposed at the second end of the driving arm 207 .

[0088] In one embodiment, referring to the attached Figure 3 To Attachment Fig. 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 driving rod 210. The driving rod 210 is arranged on the rotation path of the toggle rod 305 so that the transmission frame 209 can be driven by the toggle rod 305 to move toward the direction close to the cylindrical bracket 201 to the second end of the pressing driving arm 207.

[0089] In actual application, the end of the duckbill 202 is set downward, the transmission disk 304 rotates, and then drives the toggle rod 305 to rotate. When the toggle rod 305 conflicts with 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 conflict with 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 disk 304 rotates one circle, and the duckbill 202 opens and closes once, and only a small part of the travel in one circle of the transmission disk 304 is used to drive the duckbill 202 to open, and most of the other travel The duckbill 202 is in In the closed state, since 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 times during one rotation of the transmission disk 304 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 driving rod 210 (i.e. changing the contact stroke of the toggle rod 305 and the driving 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 also includes a seedling receiving tube 400 , which is connected to the mounting bracket 100 and communicated 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 also provides a transplanter, which includes the above-mentioned planting device. The specific structure of the planting device refers to the above-mentioned embodiment. Since the present transplanter adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0094] Specifically, the mounting bracket 100 is provided with a connecting rod for connecting with 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 (inclined downward) and the planting position (vertically downward).
