It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0016] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0017] like Figures 1-6 As shown, a corn seedling transplanter provided in one embodiment of the present invention includes a frame 1, and further includes: The excavation module 2 includes a top plate 21. Two limiting rods 22 are symmetrically arranged on both sides of the top plate 21, and the limiting rods 22 are slidably mounted on the frame 1 in the vertical direction. A mounting plate 23 is arranged below the top plate 21. Several arc-shaped plates 24 are arranged in a ring around the mounting plate 23. Each arc-shaped plate 24 has a sliding connecting rod 241 at its top, and each sliding connecting rod 241 is slidably mounted on the mounting plate 23 in the radial direction. Each rod 241 is provided with an adjusting column 25, the top of each adjusting column 25 is connected to the bottom of the top plate 21, and the bottom of the top plate 21 is provided with a first sliding groove 211 that matches the adjusting column 25. The top plate 21 is also provided with an adjusting unit 3 for driving each adjusting column 25 to slide synchronously along the first sliding groove 211. Each arc plate 24 is hinged with a digging block 26 at the bottom, and the bottom of the mounting plate 23 is also provided with a control unit 4 for driving each digging block 26 to rotate synchronously. The lifting module 5 is installed on the frame 1 and connected to the limiting rod 22, and is used to drive the limiting rod 22 to move up and down in the vertical direction.

[0018] In the embodiment of the present application, when in use, the device is moved to the area where the planting hole is to be dug, and then the adjusting unit 3 is started to drive the adjusting columns 25 to slide along the first sliding grooves 211 synchronously, the adjusting columns 25 can drive the arc-shaped plates 24 to move along the radial direction of the mounting plates 23 synchronously through the sliding connecting rods 241, so as to adjust the positions of the arc-shaped plates 24, so that the device can dig different sizes of planting holes. Then the limiting connecting rods 22 are driven to move downward by the lifting module 5, so that the digging module 2 is moved downward as a whole. The digging blocks 26 are inserted into the soil at the specified position, when the digging blocks 26 reach the specified depth, the control unit 4 is started to drive the digging blocks 26 to rotate along the hinge joints between the digging blocks 26 and the arc-shaped plates 24, so as to adjust the inclination of the digging blocks 26, so that the digging blocks 26 are gathered inward after being inserted to the specified depth, so as to successfully dig the soil or corn seedlings from the ground. Then the corn seedlings are transferred to the planting hole dug in advance to realize the corn seedling replanting operation.

[0019] As shown in Figures 1-4 the adjusting unit 3 comprises a rotating column 33 rotatably mounted at the bottom of the top plate 21, and an adjusting motor 32 mounted on the top plate 21, and the output end of the adjusting motor 32 is in transmission connection with the rotating column 33 for driving the rotating column 33 to rotate, and the bottom of the rotating column 33 is provided with an adjusting turntable 31, a plurality of arc-shaped sliding grooves 311 are arranged on the adjusting turntable 31 in a ring shape, the number of the arc-shaped sliding grooves 311 is the same as that of the adjusting columns 25, and each adjusting column 25 is correspondingly mounted in one arc-shaped sliding groove 311.

[0020] In the embodiment of the present application, the output end of the adjusting motor 32 is in transmission connection with the rotating column 33 through a pair of meshing spur gears. When in use, the adjusting motor 32 is started to drive the rotating column 33 to rotate through the pair of meshing spur gears, and the rotating column 33 can drive the adjusting turntable 31 to rotate synchronously. During the rotation of the adjusting turntable 31, the adjusting columns 25 and the arc-shaped sliding grooves 311 are relatively displaced, so as to drive the adjusting columns 25 to slide along the first sliding grooves 211, and the adjusting columns 25 can drive the arc-shaped plates 24 to move along the radial direction of the mounting plates 23 synchronously through the sliding connecting rods 241, so as to adjust the positions of the arc-shaped plates 24, so that the device can dig different sizes of planting holes to meet different planting requirements.

[0021] As shown in Figure 6As shown, in a preferred embodiment of the present invention, the control unit 4 includes a first electric telescopic rod 44 installed at the bottom of the mounting plate 23. The telescopic end of the first electric telescopic rod 44 is connected to a lifting plate 41. A plurality of arc-shaped mounting plates 42 are arranged around the lifting plate 41. The number of arc-shaped mounting plates 42 is the same as the number of arc-shaped plates 24. Each arc-shaped mounting plate 42 is respectively installed on an arc-shaped plate 24 and can slide up and down along the inner wall of the arc-shaped plate 24. Each arc-shaped mounting plate 42 is connected to the lifting plate 41 through an auxiliary connecting rod 43. The two ends of the auxiliary connecting rod 43 are respectively slidably installed on the lifting plate 41 and the arc-shaped mounting plate 42 in the horizontal direction. Each arc-shaped mounting plate 42 has a connecting seat 46 at its bottom. An adjusting connecting rod 45 is hinged to the connecting seat 46. The end of each adjusting connecting rod 45 away from the connecting seat 46 is respectively hinged to the inner wall of a digging block 26.

[0022] In this embodiment of the invention, during use, the arc-shaped plate 24 moves, causing the arc-shaped mounting plate 42 to move synchronously along the horizontal direction. At this time, each digging block 26 remains relatively stationary between its corresponding adjusting rod 45. When adjusting the inclination of the digging block 26, simply control the first electric telescopic rod 44 to rise and fall. The first electric telescopic rod 44 can drive the lifting plate 41 to rise and fall synchronously. The lifting plate 41 can drive each arc-shaped mounting plate 42 to move up and down synchronously along the interior of the arc-shaped plate 24 via the auxiliary connecting rod 43. The arc-shaped mounting plate 42 can drive the adjusting rod 45 to move synchronously via the connecting seat 46, thereby causing the digging block 26 to rotate along its hinge point with the arc-shaped plate 24. This adjusts the inclination of the digging block 26, allowing it to converge inward after being inserted to a specified depth, thus smoothly digging up the soil or corn seedlings from the ground. Alternatively, each digging block 26 can be inserted directly into the soil in an inclined state, forming an approximately conical planting hole.

[0023] like Figure 1 As shown, in a preferred embodiment of the present invention, the frame 1 is provided with a first guide groove 13 that matches the limiting link 22. A guide post 11 is provided in the first guide groove 13 along the setting direction, and the limiting link 22 is slidably installed on the guide post 11 in the vertical direction. A spring 12 connected to the limiting link 22 is also sleeved on the guide post 11.

[0024] In this embodiment of the invention, the guide post 11 provides guidance for the limiting link 22, thereby ensuring that the limiting link 22 moves stably up and down along the vertical direction. At the same time, the elastic restoring force provided by the spring 12 can also provide assistance during the overall upward movement of the excavation module 2.

[0025] like Figure 1 and Figure 7As shown, in a preferred embodiment of the present invention, the lifting module 5 is provided in two sets, and the two sets of lifting modules 5 are symmetrically arranged on the frame 1. The two sets of lifting modules 5 are respectively connected to two limit rods 22, so that the two limit rods 22 can be lifted and lowered synchronously, thereby ensuring the stability of the overall movement of the digging module 2.

[0026] like Figure 1 , Figure 7 and Figure 8 As shown, in a preferred embodiment of the present invention, the lifting module 5 includes a drive motor 51 mounted on the frame 1 and a T-shaped adjusting member 54 connected to the limiting link 22. The output end of the drive motor 51 is connected to a mounting plate 52, a connecting column 53 is mounted on the mounting plate 52, and a third sliding groove 541 matching the connecting column 53 is provided on the T-shaped adjusting member 54.

[0027] In this embodiment of the invention, during use, simply start the drive motor 51. The drive motor 51 can drive the mounting plate 52 to rotate, and the mounting plate 52 can drive the connecting column 53 to rotate synchronously. During this process, through the cooperation of the connecting column 53 and the third sliding groove 541, the connecting column 53 can drive the T-shaped adjusting member 54 to move up and down as a whole. The T-shaped adjusting member 54 can drive the limiting connecting rod 22 to move up and down synchronously, thereby driving the digging module 2 to dig planting holes or dig up corn seedlings.

[0028] like Figure 1 , Figure 7 and Figure 8 As shown, in a preferred embodiment of the present invention, a second sliding groove 521 is provided on the mounting plate 52 along its radial direction, a mounting block 55 is slidably installed in the second sliding groove 521, and the connecting column 53 is installed on the mounting block 55. A second electric telescopic rod 56 for driving the mounting block 55 to slide in the second sliding groove 521 is also provided in the second sliding groove 521.

[0029] In this embodiment of the invention, during use, by controlling the retraction of the second electric telescopic rod 56, the mounting block 55 can be moved radially along the mounting plate 52 in the second sliding groove 521, thereby adjusting the distance between the axis of the mounting block 55 and the mounting plate 52. The mounting block 55 can drive the connecting column 53 to move synchronously, thereby adjusting the distance between the highest and lowest points of the connecting column 53 rotating one revolution, thus adjusting the downward movement distance of the limiting connecting rod 22, thereby adjusting the depth of the digging module 2 inserted into the ground. This allows for the digging of planting holes of different depths according to usage requirements, further meeting different usage needs.

[0030] In a preferred embodiment of the present invention, the frame 1 may be equipped with a handle and casters at the bottom, allowing for easy movement by manually pushing the device, thus facilitating operations such as digging planting holes and transplanting seedlings. Alternatively, the device can be directly integrated into an existing field mobile platform to achieve automated corn replanting.

[0031] Working principle: In use, the entire device is moved to the area where planting holes need to be dug, and then the adjusting motor 32 is started. The adjusting motor 32 drives the rotating column 33 to rotate through a pair of meshing spur gears. The rotating column 33 drives the adjusting turntable 31 to rotate synchronously. During the rotation of the adjusting turntable 31, a relative displacement occurs between the adjusting column 25 and the arc-shaped sliding groove 311, thereby pushing the adjusting column 25 to slide along the first sliding groove 211. The adjusting column 25 drives the arc-shaped plate 24 to move synchronously along the radial direction of the mounting plate 23 through the sliding connecting rod 241, thereby adjusting the position of each arc-shaped plate 24 so that the device can dig planting holes of different sizes. Then, the drive motor 51 is started, which can drive the mounting plate 52 to rotate. The mounting plate 52 can drive the connecting column 53 to rotate synchronously. During this process, through the cooperation of the connecting column 53 and the third sliding groove 541, the connecting column 53 can drive the T-shaped adjusting member 54 to move up and down as a whole. The T-shaped adjusting member 54 can drive the limiting connecting rod 22 to move up and down synchronously, thereby driving the excavation module 2 to move downward as a whole. The excavator block 26 is inserted into the soil at a designated location. Once the excavator block 26 reaches the designated depth, the first electric telescopic rod 44 is raised and lowered. The first electric telescopic rod 44 can drive the lifting plate 41 to rise and fall synchronously. The lifting plate 41 can drive each arc-shaped mounting plate 42 to move up and down synchronously along the interior of the arc-shaped plate 24 via the auxiliary connecting rod 43. The arc-shaped mounting plate 42 can drive the adjusting connecting rod 45 to move synchronously via the connecting seat 46, thereby causing the excavator block 26 to rotate along its hinge point with the arc-shaped plate 24. This adjusts the inclination of the excavator block 26, allowing it to converge inward after being inserted to the designated depth, thus successfully digging up the soil or corn seedlings from the ground. Afterwards, the corn seedlings can be transferred to the pre-dug planting holes to complete the replanting operation.
