[0055] Example 1:

[0056] See Figure 1 A seedling transplanting device that can flexibly clamp seedlings includes a motor 1, a frame 2 having a vertical end I and a horizontal end II, and a transmission mechanism 3 disposed at the bottom of the frame 2 and connected to the output end of the motor 1 via a belt; it also includes a flexible clamping mechanism 4 fixed on the frame 2 and having a first vertical flexible belt 41 and a second flexible belt 51.

[0057] The second flexible strip 51 includes a horizontal portion III and a vertical portion IV, and there is a gap between the vertical portion IV of the second flexible strip 51 and the first vertical flexible strip 41.

[0058] The flexible clamping mechanism 4 also includes a gap adjustment mechanism 6 disposed between the vertical portion IV of the second flexible strip 51 and the first vertical flexible strip 41, for adjusting the gap size between the vertical portion IV of the second flexible strip 51 and the first vertical flexible strip 41;

[0059] One end of the inner pressure gap adjustment mechanism 6 of the first vertical flexible belt 41, and the other end of the inner pressure gap adjustment mechanism 6 of the vertical portion IV of the second flexible belt 51.

[0060] The first vertical flexible strip 41 and the second flexible strip 51 are made of PVC as the base material, and the surface of the base material is coated with silicone or rubber with good elasticity.

[0061] Initially, the gap between the first vertical flexible belt 41 and the vertical portion IV of the second flexible belt 51 is at its maximum. This gap is optimally larger than the maximum seedling size. At this time, the first vertical flexible belt 41 and the vertical portion IV of the second flexible belt 51 are parallel. Then, according to the seedling size, the gap is continuously reduced by the spacing adjustment mechanism 6 to adapt to the seedling size. At this time, the two flexible belts transport the seedling downwards in an S-shape in the vertical direction.

[0062] The gap between the vertical portions IV of the first vertical flexible belt 41 and the second flexible belt 51 is adjusted by the spacing adjustment mechanism 6, so that the two flexible belts generate a clamping force on the seedling. The transmission mechanism 3 then drives the first vertical flexible belt 41 and the second flexible belt 51 to move synchronously. The first vertical flexible belt 41 and the second flexible belt 51 moving in the same direction guide the seedling to move downward, thereby realizing the clamping and seedling placement functions of the flexible clamping mechanism 4.

[0063] In this embodiment, three sets of spacing adjustment mechanisms 6 are provided. When each set of spacing adjustment mechanisms 6 is in operation, the spacing is kept consistent to enhance the stability of the movement of the first vertical flexible belt 41 and the second flexible belt 51 and reduce seedling damage. By setting the spacing adjustment mechanism 6, seedlings of multiple levels can be clamped and placed, thereby improving the efficiency of operation.

[0064] This application uses a spacing adjustment mechanism 6 to change the horizontal distance between the vertical portion Ⅳ of the second flexible strip 51 and the first vertical flexible strip 41, thereby adjusting the clamping size of the flexible clamping mechanism 4 to accommodate seedlings of different sizes.

[0065] This application achieves flexible clamping of seedlings by guiding the seedlings into the clamping gap formed by the first vertical flexible belt 41 and the second flexible belt 51, and by providing clamping force to the seedlings through the spacing adjustment mechanism 6, the first vertical flexible belt 41 and the second flexible belt 51.

[0066] This application effectively reduces damage to seedlings during transportation and clamping by utilizing the combined effect of the clamping size and clamping material of the flexible clamping mechanism 4, thereby improving the survival rate of transplanted seedlings.

[0067] Example 2:

[0068] See Figure 1-4The flexible clamping mechanism 4 further includes a first short cantilever shaft 42 disposed on the upper part of the vertical end I of the frame 2 and a second short cantilever shaft 43 disposed on the lower part of the vertical end I of the frame 2. One end of the first short cantilever shaft 42 is fixed on the vertical end I of the frame 2, and one end of the second short cantilever shaft 43 passes through the frame 2 and is connected to the transmission mechanism 3.

[0069] The first vertical flexible belt 41 is respectively wound around the first short cantilever shaft 42 and the second short cantilever shaft 43 to form a loop.

[0070] The flexible clamping mechanism 4 also includes a first long cantilever shaft 52 and a second long cantilever shaft 53 fixed to the horizontal end II of the frame 2, and a third long cantilever shaft 54 ​​fixed to the lower part of the vertical end I of the frame 2. It also includes a fourth long cantilever shaft 55 for auxiliary support of the second flexible belt 51. One end of the third long cantilever shaft 54 ​​passes through the frame 2 and is connected to the transmission mechanism 3.

[0071] The second flexible belt 51 is respectively wound around the first long cantilever shaft 52, the second long cantilever shaft 53, the third long cantilever shaft 54 ​​and the fourth long cantilever shaft 55 to form a loop.

[0072] The second short cantilever shaft 43 and the third long cantilever shaft 54 ​​are both drive shafts of the transmission mechanism 3. A second bearing seat 432 for fixing the second short cantilever shaft 43 is installed on the frame 2. The second short cantilever shaft 43 passes through the frame 2 and the second bearing seat 432 in sequence to form a short cantilever. A third bearing seat (not shown in the figure) for fixing the third long cantilever shaft 54 ​​is installed on the frame 2. The third long cantilever shaft 54 ​​passes through the frame 2 and the third bearing seat 433 in sequence to form a long cantilever.

[0073] The first short cantilever shaft 42 is a fixed shaft. One end of the first short cantilever shaft 42 is embedded in the vertical end I of the frame 2 and fixed to the vertical end I by bolts and nuts. A bearing is sleeved on the first short cantilever shaft 42.

[0074] The first long cantilever shaft 52, the second long cantilever shaft 53, and the fourth long cantilever shaft 55 are all fixed shafts. One end of the first long cantilever shaft 52 and the second long cantilever shaft 53 are respectively embedded in the horizontal end II of the frame 2, and the two are fixed to the horizontal end II by bolts and nuts. One end of the fourth long cantilever shaft 55 is embedded in the inclined frame 21 and fixed to the inclined frame 21 by bolts and nuts. Bearings are all sleeved on the first long cantilever shaft 52, the second long cantilever shaft 53, and the fourth long cantilever shaft 55.

[0075] Among them, the motor 1 drives the transmission mechanism 3 to move, the transmission mechanism 3 drives the second short cantilever shaft 43 and the third long cantilever shaft 54 ​​to rotate, and the third long cantilever shaft 54 ​​drives the second flexible belt 51 to move, thereby realizing the conveying function of the horizontal part III of the second flexible belt 51.

[0076] Taking the first set of spacing adjustment mechanisms 6 as an example, the first crankshaft 601, the second crankshaft 602, and the third crankshaft 603 are alternately and equidistantly installed between the vertical portion IV of the second flexible belt 51 and the first vertical flexible belt 41;

[0077] By alternating and equidistantly installing the first crankshaft 601, the second crankshaft 602, and the third crankshaft 603, the same amount of tension force is applied to the vertical portion IV of the first vertical flexible belt 41 and the second flexible belt 51, so that the tension force on the two flexible belts in the vertical direction is uniform, the seedlings are not easy to fall off the clamp, and the stability of the seedling clamp is enhanced.

[0078] The first crankshaft 601 and the second crankshaft 602 are disposed on the same vertical plane and are both tangent to the inner side of the first vertical flexible belt 41, and the third crankshaft 603 is tangent to the inner side of the second flexible belt 51.

[0079] The fact that the first crankshaft 601 and the second crankshaft 602 are set on the same vertical plane can enhance the sag of the first vertical flexible belt 41 in the vertical direction. The fact that the first short cantilever shaft 42 and the second short cantilever shaft 43 are on the same vertical plane can enhance the sag of the second flexible belt 51 in the vertical part IV. This increases the parallelism of the belt surfaces of the two flexible belts, which helps to reduce the impact of belt surface unevenness on the spacing adjustment and improves the accuracy of the spacing adjustment of the first vertical flexible belt 41 and the second flexible belt 51.

[0080] The first long cantilever shaft 52 and the second long cantilever shaft 53 are set on the same horizontal plane to avoid the slope of the horizontal part III of the second flexible belt 51, thereby avoiding the problem of seedlings slipping due to the slope during transportation; the expansion and contraction force of the first vertical flexible belt 41 and the second flexible belt 51 makes the surface of the first vertical flexible belt 41 and the second flexible belt 51 flat, avoiding the bumps caused by the uneven surface of the two flexible belts during movement, which would damage the seedlings;

[0081] By having the first crankshaft 601 and the second crankshaft 602 tangent to the inner side of the first vertical flexible belt 41, respectively, the first crankshaft 601 and the second crankshaft 602 are more closely fitted to the first vertical flexible belt 41. By having the third crankshaft 603 tangent to the inner side of the second flexible belt 51, the third crankshaft 603 and the second flexible belt 51 are more closely fitted, thereby providing a certain tension to the first vertical flexible belt 41 and the second flexible belt 51, improving the transmission performance of the two flexible belts, and also enhancing the adjustability of the clamping size, thus facilitating clamping operations.

[0082] The spacing adjustment mechanism 6 also includes a fixed shaft 63 and three sets of single-ear support plates 64;

[0083] The fixed shaft 63 includes a first fixed shaft 631, a second fixed shaft 632, and a third fixed shaft 633;

[0084] The three sets of single ear pads 64 include a first single ear pad 641, a second single ear pad 642, and a third single ear pad 643.

[0085] One end of the first crankshaft 601 passes through the upper opening of the mounting plate 62 and is connected to the first fixed shaft 631 through the first single-ear support plate 641; one end of the second crankshaft 602 passes through the lower opening of the mounting plate 62 and is connected to the second fixed shaft 632 through the second single-ear support plate 642; the third crankshaft 603 is connected to the third fixed shaft 633 through the third single-ear support plate 643.

[0086] The first fixed shaft 631, the second fixed shaft 632, and the third fixed shaft 633 are all fixed to the vertical end I of the frame 2 via the first bearing seat 431.

[0087] Each set of single ear support plates 64 includes a left single ear support plate 8 and a right single ear support plate 9. The left single ear support plate 8 has an opening through which the crankshaft 60 can pass. The left single ear support plate 8 is hinged to the crankshaft 60 through the opening, and the hinge is locked and fixed by a first locking nut 604. The right single ear support plate 9 has an opening through which the fixed shaft 63 can pass. The right single ear support plate 9 is hinged to the fixed shaft 63 through the opening, and the hinge is locked and fixed by a second locking nut 605. The left single ear support plate 8 and the right single ear support plate 9 are connected and fixed into a single structure by two bolts and nuts.

[0088] One end of the first crankshaft 601 passes through the upper opening of the mounting plate 62 and is connected to the first fixed shaft 631 through the first single-ear support plate 641; one end of the second crankshaft 602 passes through the lower opening of the mounting plate 62 and is connected to the second fixed shaft 632 through the second single-ear support plate 642; the third crankshaft 603 is connected to the third fixed shaft 633 through the third single-ear support plate 643.

[0089] The first fixed shaft 631, the second fixed shaft 632, and the third fixed shaft 633 are respectively fixed to the vertical end I of the frame 2 through three first bearing seats 431.

[0090] The adjusting assembly 61 includes a hinge bolt 611 and a disc nut 612;

[0091] The hinged end of the hinge bolt 611 is fitted at the connection between the third crankshaft 603 and the third fixed shaft 633. The mounting plate 62 has a long through hole 621 in the middle for the bolt to move. The threaded end of the hinge bolt 611 passes through the long through hole 621 of the mounting plate 62 and cooperates with the disc nut 612 to form a bolt pair.

[0092] The clamping size of the flexible clamping mechanism 4 is adjusted according to the size of the seedling. By rotating the disc nut 612 counterclockwise to loosen the hinge bolt 611, the hinge bolt 611 is driven to move horizontally to change the horizontal distance between the third crankshaft 603 and the first crankshaft 601 and the second crankshaft 602, thereby changing the distance between the vertical portion IV of the first vertical flexible belt 41 and the second flexible belt 51. By rotating the disc nut 612 clockwise to tighten the hinge bolt 611, the distance between the first vertical flexible belt 41 and the second flexible belt 51 is limited, thereby realizing the adjustment of the clamping size of the flexible clamping mechanism 4.

[0093] By cooperating with the crankshaft 60 and the adjustment component 61, the flexible clamping mechanism 4 can be adjusted to various clamping sizes, effectively increasing the applicability of the device.

[0094] Short rollers 44 are fitted on both the first short cantilever shaft 42 and the second short cantilever shaft 43, and the first vertical flexible belt 41 is fitted on the short rollers 44.

[0095] Long rollers 56 are fitted on the first long cantilever shaft 52, the second long cantilever shaft 53, the third long cantilever shaft 54 ​​and the fourth long cantilever shaft 55, and the second flexible belt 51 is fitted on the long rollers 56.

[0096] By setting multiple short rollers 44, the rotational motion of the second short cantilever shaft 43 can be converted into the linear motion of the first vertical flexible belt 41. The first vertical flexible belt 41 forms a loop through the short rollers 44 on the first short cantilever shaft 42 and the second short cantilever shaft 43. By setting multiple long rollers 56, the rotational motion of the third long cantilever shaft 54 ​​can be converted into the linear motion of the second flexible belt 51. The second flexible belt 51 forms a loop through the long rollers 56 on the first long cantilever shaft 52, the second long cantilever shaft 53, the third long cantilever shaft 54 ​​and the fourth long cantilever shaft 55. Through the two sets of loops, the continuous operation of the flexible clamping mechanism 4 can be realized.

[0097] The first short cantilever shaft 42 is rotatably connected to the short roller 44, and the second short cantilever shaft 43 is fixedly connected to the short roller 44;

[0098] The first long cantilever shaft 52, the second long cantilever shaft 53, the fourth long cantilever shaft 55 and the long roller 56 are rotatably connected, and the third long cantilever shaft 54 ​​is fixedly connected to the long roller 56.

[0099] Among them, there are two bearings sleeved on the first short cantilever shaft 42, the short roller 44 is sleeved on the bearing, the inner ring of the bearing is fixed on the shaft by a nut, the outer ring of the bearing can rotate freely, and the first vertical flexible belt 41 can drive the outer ring of the bearing to rotate when it moves.

[0100] The second short cantilever shaft 43 is provided with three set screws 45 at both ends. The second short cantilever shaft 43 and the short roller 44 are circumferentially fixed by the set screws 45. The second short cantilever shaft 43 and the short roller 44 are axially fixed by the shaft shoulder and nut. When the second short cantilever shaft 43 rotates, it can drive the short roller 44 to rotate.

[0101] Two bearings are fitted on each of the first long cantilever shaft 52, the second long cantilever shaft 53, and the fourth long cantilever shaft 55. Three long rollers 56 are respectively fitted on the bearings of the first long cantilever shaft 52, the second long cantilever shaft 53, and the fourth long cantilever shaft 55. The inner ring of the bearing is fixed to the shaft by a nut, and the outer ring of the bearing can rotate freely. When the second flexible belt 51 moves, it can drive the outer ring of the bearing to rotate.

[0102] The third long cantilever shaft 54 ​​has three set screws 45 at each end. The third long cantilever shaft 54 ​​and the long roller 56 are circumferentially fixed by the set screws 45. The third long cantilever shaft 54 ​​and the long roller 56 are axially fixed by the shaft shoulder and nut. When the third long cantilever shaft 54 ​​rotates, it can drive the long roller 56 to rotate.

[0103] The transmission mechanism 3 drives the second short cantilever shaft 43 to rotate, which in turn drives the short roller 44 to rotate, and the short roller 44 drives the first vertical flexible belt 41 to move. The transmission mechanism 3 also drives the third long cantilever shaft 54 ​​to rotate, which in turn drives the long roller 56 to rotate, and the long roller 56 drives the second flexible belt 51 to move. Through the cooperation of the second short cantilever shaft 43, the third long cantilever shaft 54, the short roller 44, and the long roller 56, power is effectively transmitted to the first vertical flexible belt 41 and the second flexible belt 51, thereby realizing the movement of the flexible clamping mechanism 4 and achieving the transportation, clamping, and placement of seedlings. Simultaneously, the use of flexible materials effectively reduces friction and impact damage between the seedlings and the conveyor belt, enhancing the protection of the seedlings and ensuring their integrity.

[0104] Example 3:

[0105] See Figure 5 The transmission mechanism 3 includes a keyless pulley 30, a gear 31, and a synchronous belt 32;

[0106] The keyless pulley 30 includes a driving pulley 301 and a driven pulley 302. The driving pulley 301 is installed at the output end of the motor 1, and the driven pulley 302 is installed at one end of the second short cantilever shaft 43.

[0107] Gear 31 includes a first gear 311 and a second gear 312. The first gear 311 is mounted at one end of the second short cantilever shaft 43 and is located on one side of the driven pulley 302. The second gear 312 is mounted at one end of the third long cantilever shaft 54 ​​and meshes with the first gear 311.

[0108] Synchronous belt 32 is set on driving pulley 301 and driven pulley 302;

[0109] After the second short cantilever shaft 43 passes through the frame 2, it passes through the first gear 311 and the driving pulley 301 in sequence. The first gear 311 and the second short cantilever shaft 43 are circumferentially fixed by a key connection. The first gear 311 and the second short cantilever shaft 43 are axially fixed by a shaft shoulder and a nut. The second short cantilever shaft 43 and the driven pulley 302 are fixed by bolts and nuts.

[0110] In this embodiment, the synchronous belt 32 transmits the motion of the motor 1 from the driving pulley 301 to the driven pulley 302. The driven pulley 302 simultaneously drives the first gear 311 and the second short cantilever shaft 43 to move. The first gear 311 transmits power to the second gear 312 through gear meshing. The second gear 312 drives the third long cantilever shaft 54 ​​to move. Since the first gear 311 and the second gear 312 have the same number of teeth, their rotational speeds are always consistent. Furthermore, the rotational speeds of the second short cantilever shaft 43 and the third long cantilever shaft 54 ​​are also consistent. This ensures that the movement speeds of the first vertical flexible belt 41 and the second flexible belt 51 are always synchronized, enhancing the stability of the movement. This achieves stable seedling transmission and clamping, effectively reducing damage to the seedlings during the movement process. By controlling the speed of the synchronous belt 32, the spacing between seedlings is kept consistent, avoiding changes in the transplanting spacing due to fluctuations in the machine's forward speed.

[0111] See Figure 7 An inclined frame 21 for mounting a fourth long cantilever shaft 55 extends from the junction of the vertical end I and the horizontal end II of the frame 2.

[0112] Vertical rods and horizontal rods extend from the vertical end I and horizontal end II of the frame 2, respectively, to fix the end of the inclined frame 21 and enhance the stability of the inclined frame 21 so that the long roller 56 on the fourth long cantilever shaft 55 can rotate more stably.

[0113] The bottom of the frame 2 is also provided with a mounting bracket 22 for fixing the motor 1. The mounting bracket 22 has an opening, through which the output shaft of the motor 1 passes and is connected to the drive pulley 301.

[0114] The mounting bracket 22 increases the contact area of ​​the motor 1 at the bottom of the frame 2, thereby enhancing the installation stability of the motor 1 and dispersing the impact force brought by the vibration of the motor 1, preventing the bottom of the frame 2 from being damaged by continuous impact.

[0115] See Figure 1 and Figure 6The working process of this application is as follows: When transplanting seedlings, the spacing adjustment mechanism 6 is first adjusted according to the size of the seedlings so that the clamping size of the flexible clamping mechanism 4 matches the size of the seedlings. Then, the seedlings raised in the field are placed on the horizontal part III of the second flexible belt 51 at a fixed spacing. The motor 1 is started, and the motor 1 transmits the rotational motion to the second short cantilever shaft 43 and the third long cantilever shaft 54 ​​through the transmission mechanism 3. The third long cantilever shaft 54 ​​drives the second flexible belt 51 to move. The seedlings will move towards the first vertical flexible belt 41 under the support of the horizontal part III of the second flexible belt 51. The second short cantilever shaft 43 drives the first vertical flexible belt 41 to move. After the seedlings enter the gap between the first vertical flexible belt 41 and the second flexible belt 51, they are vertically transported to the ground through the clamping and guidance of the crankshaft 60 and the two flexible belts, thus completing the seedling transplanting.

[0116] In summary, this invention provides a flexible seedling clamping transplanting device that achieves flexible seedling transport, flexible clamping, and self-adjustment of plant spacing. This effectively reduces damage to seedlings during transplanting, maintains seedling integrity, and increases the survival rate of transplanted seedlings. It is also applicable to seedlings of different sizes and grades, has a wide range of applications, and is suitable for standard seedling transplanting operations. While improving seedling transplanting efficiency, it also reduces the labor intensity of farmers.
