[0035] For example, Figures 1 to 6As shown in the drawings, the embodiment provides a seedling guiding mechanism and a hand-held transplanter. The seedling guiding mechanism and the hand-held transplanter comprise an outer cover body 1. A first guide rail 2 is fixedly installed on the inner side of the outer cover body 1. The first guide rail 2 extends into the outer cover body 1 and is downwardly inclined at one end. A second guide rail 3 is fixedly installed at the end of the first guide rail 2 protruding out of the outer cover body 1. The end of the second guide rail 3 close to the first guide rail 2 is also downwardly inclined. A first baffle 4 is arranged at the connection between the first guide rail 2 and the second guide rail 3. The first baffle 4 is movably connected to the outer side of the outer cover body 1. A seedling guiding cylinder 5 is movably connected in the outer cover body 1. The seedling guiding cylinder 5 is sleeved in the outer cover body 1 and is in clearance fit with the outer cover body 1. An inlet 6 is formed in the inner side of the seedling guiding cylinder 5. A second baffle 7 is movably connected to the side of the inlet 6 close to the first guide rail 2. The second baffle 7 is arranged in parallel with the first baffle 4. The inclination angles of the first guide rail 2 and the second guide rail 3 are 15 degrees and 30 degrees, respectively. The inner sides of the first guide rail 2 and the second guide rail 3 are smooth surfaces with extremely small friction. Only one seedling can be accommodated on the first guide rail 2. The first guide rail 2 can convey linearly arranged seedlings into the outer cover body 1 through the inclined second guide rail 3. The first baffle 4 can separate the single seedling on the first guide rail 2 from the seedlings on the second guide rail 3 when the first baffle 4 is in the raised state. The seedling on the first guide rail 2 can enter the seedling guiding cylinder 5 through the inlet 6. The second baffle 7 can separate the seedling on the first guide rail 2 from the inlet 6 when the second baffle 7 is in the lowered state. Thus, only one seedling can enter the seedling guiding cylinder 5 at a time, so as to avoid blockage.

[0036] A sleeve 8 is further fixedly installed on the outer side of the first guide rail 2. A jacking rod 9 is movably connected in the sleeve 8. The end of the jacking rod 9 protruding out of the sleeve 8 is fixedly connected to the bottom of the first baffle 4. A spring 10 is further arranged in the sleeve 8. The spring 10 is sleeved on the jacking rod 9. The jacking rod 9 has an integral stop ring part. The two ends of the spring 10 are connected with the sleeve 8 and the stop ring part, respectively. When the spring 10 is in the stretched state, the jacking rod 9 is pushed out of the sleeve 8 and moves along the axial direction of the sleeve 8. The first baffle 4 is jacked up from the first guide rail 2, so that the first baffle 4 is in the raised state and the seedling on the first guide rail 2 is separated from the seedlings on the second guide rail 3.

[0037] A limiting rod 11 is fixedly installed on the inner side of the outer cover body 1 and is located above the second guide rail 3. A sliding groove 12 adapted to the limiting rod 11 is formed in the end of the second baffle 7 away from the first guide rail 2. The second baffle 7 is slidably installed on the limiting rod 11 through the sliding groove 12. The limiting rod 11 is located at the lowest point in the sliding groove 12 when the second baffle 7 is in the raised state. At this time, the seedling in the first guide rail 2 can enter the seedling guiding cylinder 5 through the inlet 6.

[0038] The outer side of the seedling guiding cylinder 5 is fixedly provided with a first pressing strip 13 matched with the first baffle 4 and a second pressing strip 14 matched with the second baffle 7, and the outer cover body 1 is provided with a guide groove for limiting the sliding of the first pressing strip 13 and the second pressing strip 14. The outer side of the seedling guiding cylinder 5 is further fixedly provided with a threaded sliding block 15 arranged in parallel with the first pressing strip 13, and the threaded sliding block 15 is located below the outer cover body 1. When the first pressing strip 13 contacts the first baffle 4, the first baffle 4 is extruded to be converted to a falling state in the first guide rail 2. When the second pressing strip 14 contacts the second baffle 7, the second baffle 7 is supported to be in a rising state in the first guide rail 2.

[0039] The hand-held transplanter comprises a seedling guiding mechanism and a base 16. The top of the base 16 is fixedly provided with a stand 17 and a motor 19. One end of the stand 17 is fixedly provided at the bottom of the second guide rail 3. The top of the base 16 is further provided with a threaded shaft 18 arranged in parallel with the stand 17. One end of the threaded shaft 18 close to the base 16 is in transmission connection with the output shaft of the motor 19. The threaded shaft 18 is in threaded connection with the threaded sliding block 15. One end of the threaded sliding block 15 away from the seedling guiding cylinder 5 extends into the stand 17. The base 16 can ensure the stability of the seedling sliding in the second guide rail 3 through the stand 17. The motor 19 can drive the threaded shaft 18 to rotate, thereby driving the seedling guiding cylinder 5 connected with the threaded sliding block 15 to move in the outer cover body 1, so as to accurately send the seedling to the seedling hole in the land.

[0040] The inner side of the base 16 is provided with an operation hole 20 matched with the seedling guiding cylinder 5. The base 16 is in clearance fit with the seedling guiding cylinder 5. The operation hole 20 can ensure that the angle between the seedling guiding cylinder 5 and the base 16 is always unchanged when the seedling guiding cylinder 5 moves in the outer cover body 1.

[0041] The base 16 is provided with moving wheels 21 arranged around the base 16. The moving wheels 21 are all located below the base 16. The outer side of the base 16 is further fixedly provided with a handle 22. One end of the handle 22 away from the base 16 is inclined upward. The moving wheels 21 can increase the distance between the base 16 and the land, so as to facilitate the movement of the device. The handle 22 is convenient to grip, so that the device can be operated by hand.

[0042] In use, the motor 19 is driven to rotate by the output shaft of the motor 19, so that the threaded sliding block 15 connected by threads drives the seedling guiding cylinder 5 to move along the axial direction of the outer cover body 1 under the restriction of the operation hole 20 in the base 16, so as to accurately deliver the seedlings transported into the seedling inlet 6 in the seedling guiding cylinder 5 to the seedling hole in the land, and meanwhile, the distance between the base 16 and the land is increased by the moving wheel 21, the base 16 is moved by holding the handle 22, and the device is manually operated to ensure the stability of the device, and in this process, when the seedling guiding cylinder 5 descends in the outer cover body 1, the first pressing strip 13 extrudes the first baffle 4, so that the first baffle 4 separating the single seedling on the first guide rail 2 from the seedlings on the second guide rail 3 is switched to the falling state from the raised state, and the linearly arranged seedlings on the second guide rail 3 are transported to the first guide rail 2 which can only accommodate one seedling, at this time, the second baffle 7 loses the support of the second pressing strip 14, and falls from above the first guide rail 2 under the restriction of the sliding groove 12, separates the seedlings on the first guide rail 2 from the seedling inlet 6 in the seedling guiding cylinder 5, so that only one seedling can enter the seedling guiding cylinder 5 at a time, avoiding blockage, and when the seedling guiding cylinder 5 rises, the spring 10 in the sleeve 8 restores and extends, pushes the top rod 9 to protrude from the sleeve 8, and makes the first baffle 4 rise in the first guide rail 2, so as to realize the automatic closing of the channel of the seedlings in the second guide rail 3 into the first guide rail 2, and reduce the probability of pollution caused by the long-term opening of the hole in the outer cover body 1 which is communicated with the second guide rail 3.
