Description

Technical Field

[0001] This invention relates to the field of auxiliary planting devices, specifically to an auxiliary device for seedling planting in hot and humid regions. Background Technology

[0002] The banana plant is a perennial herbaceous plant belonging to the genus Musa in the family Musaceae. It has a relatively long rhizome and strong regeneration ability. Its leaves are oblong, bright green, with thick petioles, and reddish-brown or purple bracts. Native to the Ryukyu Islands, the banana plant prefers a warm and sunny environment, but can also tolerate shade. However, temperatures exceeding 40°C can easily lead to plant death. It has high requirements for soil, needing deep, loose, fertile, and well-drained soil. Banana plants are mostly grown in greenhouses, which requires manual digging, planting, and filling of holes, resulting in low planting efficiency, low survival rate, and increased project costs.

[0003] Before planting banana seedlings, the soil needs to be loosened or aeration holes made to increase the permeability of the root zone and create suitable conditions for root growth. Existing seedling planting auxiliary equipment is bulky and unsuitable for indoor planting work. It also tends to over-compact or sunken the planting pits, requiring frequent shallow watering, which can easily lead to root rot in banana seedlings. When planting bananas in greenhouses, digging pits and loosening the soil requires manual filling, affecting the efficiency of seedling planting. In addition, existing planting auxiliary equipment cannot ensure that the planted seedlings are perpendicular to the ground, which can easily cause the seedlings to tilt. It also requires manual bending over for planting, resulting in low efficiency and wasted human resources.

[0004] In view of the above, in order to overcome the above technical problems, the present invention designs an auxiliary device for seedling planting in hot and humid areas, which solves the above technical problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the existing seedling planting auxiliary equipment requires manual filling of the pit and planting after digging the pit and loosening the soil, and requires manual bending over to plant, which makes the banana seedling planting process inefficient and wastes human resources.

[0006] To address the above problems, the present invention provides the following technical solution:

[0007] This invention provides an auxiliary device for seedling planting in hot and humid areas, comprising a shell, a handle, and a support. The handle and support are installed on the outer side of the shell. It also includes a transmission device and a lifting device. The transmission device is connected to the shell and drives the shell to dig a trench by transmitting an externally applied thrust. The trench is then filled by a rotating wheel. Simultaneously, the rotating wheel drives the lifting device to move up and down. The lifting device drives a rectangular slider to move horizontally back and forth through the rotating wheel. The rectangular slider drives a threaded rod to rotate through the back and forth motion, which in turn drives the track to move forward intermittently. The rotation of the threaded rod drives the fixed clamp to rise and fall. The up and down moving fixed clamp clamps clamp and release the seedlings to plant them into the trench.

[0008] The bracket is installed on the outside of the shell to connect and fix the transmission device to the shell. This allows the shell to be pushed forward to dig the soil when the transmission device is pushed. After the shell digs the soil to form a trench, the transmission device fills and compacts the trench at the same time. This prevents the pit from sinking after the soil is filled in hot and humid areas. In hot and humid areas where water is needed, frequent watering of banana seedlings can lead to waterlogging and root rot. This ensures the survival rate of banana seedlings. While filling the pit, the transmission device transmits the thrust to the lifting device, which moves the banana seedlings up and down. This eliminates the need for manual bending to plant the seedlings, reducing the waste of human resources.

[0009] The transmission device includes a rotating wheel, a rotating rod, a connecting rod, a rectangular slider, a transmission rack, a spur gear, and a threaded rod. The rotating wheel is connected to the bracket and is frustum-shaped, with strip-shaped protrusions arranged on its outer side. One end of the rotating rod is rotatably mounted on an eccentric position of one of the rotating wheels, and the other end of the rotating rod is rotatably connected to one end of the connecting rod. A rectangular slider is fixedly mounted on the other end of the connecting rod, and the height of the rectangular slider is greater than the diameter of the connecting rod. A transmission rack is fixedly mounted on the side of the rectangular slider, and the transmission rack slides against the upper surface of the outer shell. The transmission rack meshes with the spur gear, and a threaded rod is fixedly mounted on the lower end of the spur gear. The upper part of the threaded rod is rotatably connected to the upper surface of the outer shell.

[0010] The outer casing at the front of the rotary wheel pushes the soil upside down to form a trench. The soil is lifted from the inside out and piled up beside the trench. The rotary wheel is shaped like a frustum, so as it rotates and moves forward, it pushes the soil piled up beside the trench into the trench through the sides of the frustum and compacts it, causing the soil to slope outwards from the center of the trench. The outer side of the frustum-shaped rotary wheel has an array of strip-shaped protrusions, which, during the compaction process, press out these strip-shaped diagonal grooves, preventing over-compaction or sunken tree pits, and enhancing soil aeration in hot and humid regions. When banana seedlings are frequently watered shallowly, excess water can flow out along the sloping ditch, thus preventing root rot and increasing the survival rate of banana seedlings. The rotating rod is installed at the eccentric position of the rotating wheel, which allows the rotating wheel to pull the transmission rack back and forth during rotation. The height of the rectangular slider is greater than the diameter of the connecting rod, which can limit the connecting rod during sliding, thereby stabilizing the meshing of the transmission rack and the spur gear, driving the spur gear and the threaded rod to rotate back and forth, realizing the reciprocating lifting process of the lifting device.

[0011] A seedling rack is fixedly installed at the upper end of the outer shell, and a sliding groove for the connecting rod to slide is opened on the side of the seedling rack near the connecting rod; a through hole for the threaded rod to rotate is opened on the upper surface of the outer shell, and the diameter of the through hole is the same as the diameter of the threaded rod.

[0012] The upper part of the seedling rack is concave, facilitating the placement of seedlings and making the planting process more convenient. The lower part of the seedling rack is fixedly connected to the upper part of the outer shell, protecting the transmission rack and spur gear in the transmission device and preventing dust from falling during planting from affecting the transmission path. A groove is provided on the side of the seedling rack near the connecting rod, allowing the pull rod to pass through the rack and pull a rectangular slider to slide within the groove. The rectangular slider and the groove limit the pull rod, ensuring its horizontal position remains unchanged during sliding and guaranteeing stable meshing of the transmission rack and spur gear. The bottom of the outer shell is a semi-triangular pyramid, concentrating the thrust exerted by the outer shell on the soil within the pyramid. The pointed corners of the triangular cone shape make the process of lifting and loosening the soil easier and more convenient. The sloping outer side of the triangular cone shape allows the excavated soil to be piled up on both sides of the shell and raised above the ground level, facilitating the compaction of the soil by the rotating wheel. It also allows control over the depth of the pit, preventing the banana seedlings from being planted too deep. The diameter of the through hole on the upper surface of the shell is the same as the diameter of the threaded rod, allowing the upper part of the threaded rod to pass through the shell and rotate and connect with it. The upper end of the threaded rod is fixedly connected to a spur gear, which converts the reciprocating rotation of the spur gear into the reciprocating rotation of the threaded rod. This keeps the position of the threaded rod fixed while transmitting the force from the transmission device to the lifting device inside the shell.

[0013] The upper end of the seedling rack is equipped with a track, and an arc-shaped hinge block is linearly arrayed on the inner side of the track. A small spring is engaged between the lower surface of the arc-shaped hinge block and the track. A locking block is fixedly installed at the connection between the arc-shaped hinge block and the track, and the locking block is perpendicular to the track.

[0014] When the track rotates, it pushes the seedlings placed on the track surface closer to the planters, making it easier for them to pick up the seedlings during planting and improving the efficiency of banana seedling planting. The locking block is perpendicular to the track, so that the rotation angle of the arc-shaped hinge block is less than 90° when the track rotates. Four fixed shafts are set at both ends of the track, and the inner side of the fixed shaft does not contact the arc-shaped hinge block to prevent interference with the normal rotation of the track.

[0015] The upper end of the rectangular slider has a hook-shaped protrusion on the side near the track, and the distance between the lower end of the hook-shaped protrusion and the inner side of the track is greater than the height of the block.

[0016] The hook-shaped protrusion allows the rectangular slider to hook onto the arc-shaped hinge block on the inner side of the track as it slides forward, causing the track to rotate. As the rectangular slider slides backward, the distance between the lower end of the hook-shaped protrusion and the inner side of the track is greater than the height of the locking block, allowing the outer arc portion of the hook-shaped protrusion to slide in close contact with the arc portion of the arc-shaped hinge block. Furthermore, the groove on the inner side of the track provides space for the rotation of the arc-shaped hinge block, preventing the track from rotating and preventing seedlings from piling up on the front side, thus improving the efficiency of banana seedling planting.

[0017] The lifting device includes a lifting plate, a sliding bevel gear, a transmission bevel gear, a transmission rod, a connecting rod, and a clamping assembly. A T-shaped protrusion is provided on one side of the lifting plate, which is slidably connected to a T-shaped groove inside the outer casing. A threaded hole is provided on the lifting plate to mate with the threaded rod. The sliding bevel gear is rotatably connected to the lifting plate and meshes with the transmission bevel gear. The eccentric position of the transmission bevel gear is rotatably connected to one end of the transmission rod, and the other end of the transmission rod is rotatably connected to one end of the connecting rod. The length of the connecting rod is equal to the length from one end of the transmission rod to the center of the transmission spur gear, and the other end of the connecting rod is connected to the clamping assembly.

[0018] The T-shaped protrusion slides in conjunction with the T-shaped groove inside the outer casing, limiting the movement of the lifting plate. This prevents the lifting plate from getting stuck on the threaded rod as it rotates with the threaded rod, thus preventing interference with the lifting process. The threaded hole engages with the threaded rod; as the rod rotates, the threaded hole slides along its outer side, allowing the lifting plate to slide up and down axially along the threaded rod. When the sliding bevel gear slides to the bottom of the inner side of the outer casing, the transmission bevel gear meshes with the sliding bevel gear and rotates half a revolution. The length of the connecting rod is equal to the distance from one end of the transmission rod to the center of the transmission bevel gear. This allows the lines connecting the transmission rod, connecting rod, the center of the transmission bevel gear, and one end of the transmission rod, as well as the line connecting the center of the transmission bevel gear and the other end of the connecting rod, to form a parallelogram. This causes the connecting rod to rotate 360° when the transmission bevel gear rotates half a revolution and then reciprocates. The transmission bevel gear is rotatably connected to the support structure on the lifting plate, fixing its position on the lifting plate and allowing it to slide up and down with it.

[0019] The sliding bevel gear has a circular hole at its center, the diameter of which is equal to the diameter of the threaded hole. A rectangular protrusion is provided on the inner side of the circular hole, and a groove that mates with the rectangular protrusion is provided on the outer side of the threaded rod.

[0020] The diameter of the round hole is larger than the diameter of the threaded rod, allowing the sliding bevel gear to slide on the outside of the threaded rod. The groove on the outside of the threaded rod ensures that the rectangular protrusion on the inside of the round hole can hold the threaded rod in place when it rotates, so that the transmission bevel gear can rotate synchronously with the threaded rod when it slides, thereby realizing the transmission of the entire device.

[0021] The sliding bevel gear has an annular protrusion below it. The inner diameter of the annular protrusion is larger than the diameter of the threaded rod. The lower end of the annular protrusion is rotatably connected to the lifting plate.

[0022] The annular protrusion is rotatably connected to the lifting plate, allowing the sliding bevel gear to slide up and down with the lifting plate while following the rotation of the threaded rod, and maintaining the horizontal distance between the sliding bevel gear and the lifting plate without changing, thus ensuring stable meshing between the sliding bevel gear and the transmission bevel gear; the annular protrusion surrounds the outside of the threaded rod, and the diameter of its inner wall is larger than the diameter of the threaded rod, so that the rotation of the sliding bevel gear does not interfere with the sliding of the lifting device on the threaded rod.

[0023] The sliding bevel gear has the same diameter and number of teeth as the spur gear, and the number of teeth of the transmission bevel gear is twice the number of teeth of the transmission rack.

[0024] The sliding bevel gear has the same diameter and number of teeth as the spur gear. When the spur gear rotates and drives the threaded rod to rotate, it drives the sliding bevel gear to rotate synchronously. Thus, when the sliding bevel gear slides to the bottom of the threaded rod, the number of rotations is the same as the number of rotations of the spur gear. When the sliding bevel gear slides to the bottom of the threaded rod, the rotating wheel rotates half a turn, driving the transmission rack to mesh with the spur gear. The spur gear rotates from one end to the other on the transmission rack. The number of teeth of the transmission bevel gear is twice the number of teeth of the transmission rack. This allows the transmission bevel gear to rotate half a turn when the lifting device slides to the bottom of the threaded rod, and the minimum value of the banana seedling planting spacing is equal to the circumference of the outer edge of the rotating wheel.

[0025] The clamping assembly includes a toothed gear, a sliding rack, a pull rod, a fixing clamp, a slide rail, and a return spring. The center of the toothed gear is fixedly connected to the other end of the connecting rod. The toothed portion of the toothed gear is centrally symmetrical, and the toothed gear meshes with the sliding rack. The sliding rack is slidably connected to a rectangular slot on the lifting plate. One end of the sliding rack is provided with a rectangular protrusion. One end of the pull rod is symmetrically and rotatably mounted on the upper surface of the rectangular protrusion. The other end of the pull rod is connected to the fixing clamp. The fixing clamp is slidably connected to the slide rail. The slide rail is fixedly installed on one side of the lifting plate, and a return spring is engaged between the slide rail and the sliding rack.

[0026] The center of the toothed gear is fixedly connected to the other end of the connecting rod, so that the toothed gear rotates once when the transmission bevel gear reciprocates for one cycle. The toothed part of the toothed gear is centrally symmetrical, so that the toothed gear meshes with the sliding rack once every half rotation. That is, it meshes with the sliding rack when the lifting device slides to the bottom and top of the threaded rod, so that the clamping component releases the fixed clamp to place the seedling when it slides to the upper end, and releases the seedling for planting when it slides to the lower end. The rectangular protrusion provides a connection space for the pull rod, so that the sliding of the sliding rack in the rectangular groove drives the pull rod to rotate, pulling the fixed clamp to release.

[0027] The fixing clamp has a concave block at one end near the slide rail, and the concave block is slidably connected to the square groove inside the slide rail.

[0028] The two ends of the concave block slide outside the square groove of the slide rail, limiting the movement of the fixing clamp so that when the pull rod pulls the fixing clamp, the fixing clamp can only slide along the square groove; a rubber pad is fixedly installed on the inner side of the fixing clamp to prevent excessive impact on the seedling when the fixing clamp tightens under the elastic force of the return spring, which would damage the seedling.

[0029] The beneficial effects of this invention are as follows:

[0030] 1. The present invention provides an auxiliary device for planting seedlings in hot and humid areas. After the outer shell is pushed to dig a trench and loosen the soil, the rotating wheel rotates behind the trench to compact the soil, causing the soil to protrude and tilt, and pressing out a water channel. This prevents root rot caused by frequent shallow watering of banana seedlings in hot and humid areas, and eliminates the need for manual filling of pits and planting, thus improving the efficiency of banana seedling planting.

[0031] 2. The present invention provides an auxiliary device for planting seedlings in hot and humid areas. The lifting device rises and falls when the rotating wheel rotates, and the banana seedlings are planted while digging and filling the pit. The planting depth is easy to control, the root system is well aerated, and there is no need for manual bending to plant the banana seedlings into the pit, thus reducing the waste of human resources.

[0032] 3. The present invention provides an auxiliary device for planting seedlings in hot and humid areas. By clamping and releasing banana seedlings through a clamping device, the planting process can be ensured that the planted seedlings remain perpendicular to the ground, preventing the seedlings from tilting and affecting their growth.

[0045] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0046] like Figure 1 As shown, a seedling planting auxiliary device for hot and humid regions includes a housing 1, a handle 2, and a support 5. The handle 2 and the support 5 are installed on the outer side of the housing 1. It also includes a transmission device 3 and a lifting device 4. The transmission device 3 is connected to the housing 1. The transmission device 3 drives the housing 1 to dig a trench by transmitting an externally applied thrust, and fills the trench by rotating a wheel 31. At the same time, the rotating wheel 31 drives the lifting device 4 to rise and fall. The lifting device 4 drives a rectangular slider 34 to move horizontally back and forth through the rotating wheel 31. The rectangular slider 34 drives a threaded rod 37 to rotate through the back and forth motion, and at the same time drives the track 14 to move forward intermittently. The rotation of the threaded rod 37 drives the fixed clamp 464 to rise and fall. The moving fixed clamp 464 clamps and releases the seedlings to plant them into the trench.

[0047] The support frame 5 connects and fixes the transmission device 3 to the outer shell 1. When using the planting auxiliary equipment, the manual application of external force pushes the transmission device 3 while simultaneously pushing the outer shell 1 forward to slide and dig the highly viscous soil. After the outer shell 1 digs open the soil to form a trench, the transmission device 3 simultaneously pushes the soil lifted on both sides of the trench to fill and compact the trench, preventing the tree pit from becoming sunken, and thus preventing water accumulation in the pit after watering, which would cause the roots of the banana seedlings to rot, ensuring the survival rate of the planted banana seedlings. While filling the pit, the transmission device 3 transmits the thrust it receives to the lifting device 4, which moves the banana seedlings up and down. There is no need for manual bending over to plant the banana seedlings, which not only greatly reduces the waste of human resources, but also improves the planting efficiency of banana seedlings.

[0048] like Figures 2 to 5 As shown, the transmission device 3 includes a rotating wheel 31, a rotating rod 32, a connecting rod 33, a rectangular slider 34, a transmission rack 35, a spur gear 36, and a threaded rod 37. The rotating wheel 31 is connected to the bracket 5 and is frustum-shaped. Strip-shaped protrusions 311 are arranged on the outer side of the frustum-shaped rotating wheel 31. One end of the rotating rod 32 is rotatably mounted on the eccentric position of one of the rotating wheels 31, and the other end of the rotating rod 32 is rotatably connected to one end of the connecting rod 33. A rectangular slider 34 is fixedly mounted on the other end of the connecting rod 33. The height of the rectangular slider 34 is greater than the diameter of the connecting rod 33. A transmission rack 35 is fixedly mounted on the side of the rectangular slider 34. The transmission rack 35 slides against the upper surface of the outer shell 1 and meshes with the spur gear 36. A threaded rod 37 is fixedly mounted on the lower end of the spur gear 36, and the upper part of the threaded rod 37 is rotatably connected to the upper surface of the outer shell 1.

[0049] When the planting auxiliary equipment is moved forward, the rotating wheel 31 pushes the soil piled up beside the ditch in front of the rotating wheel 31 into the ditch and compacts it, so that the soil slopes outward from the center of the ditch and presses out a strip-shaped sloping ditch to form a water guide channel, preventing water from accumulating after watering and damaging the roots of the seedlings; the rotating wheel 31 drives the rotating rod 32, which is installed at one end of the rotating wheel 31 at an eccentric position, to pull the connecting rod 33 at the other end to slide, and the connecting rod 33 drives the rectangular slider 34 to slide in the same direction, causing the transmission rack 35 to slide; when the rotating wheel 31 rotates one revolution, the transmission rack 35 slides back and forth under the action of tension, which in turn drives the spur gear 36 and the threaded rod 37 to rotate back and forth, realizing the reciprocating lifting process of the lifting device 4.

[0050] The transmission device 3 compacts the soil pile to prevent over-compacting of the pit, thus preventing it from affecting the aeration of the soil in hot and humid areas. At the same time, it prevents the tree pit from sinking, prevents water accumulation when banana seedlings are frequently watered shallowly, and allows excess water to flow out along the drainage channel formed by the sloping ditch, thereby preventing root rot of banana seedlings and increasing the survival rate of seedlings.

[0051] like Figure 2 and Figure 3 As shown, a seedling rack 11 is fixedly installed on the upper end of the outer shell 1. The seedling rack 11 has a sliding groove 12 on the side near the connecting rod 33 for the connecting rod 33 to slide. A through hole 13 is provided on the upper surface of the outer shell 1 for the threaded rod 37 to rotate. The diameter of the through hole 13 is the same as the diameter of the threaded rod 37.

[0052] When using the auxiliary planting equipment, the seedlings to be planted are placed on top of the seedling rack 11. When the rotating wheel 31 rotates, the connecting rod 33 slides in the groove 12 opened on the outside of the seedling rack 11. The rectangular slider 34 is locked in the groove 12 on the inside of the seedling rack 11 to limit the transmission rack 35, which drives the threaded rod 37 below the spur gear 36 to pass through the through hole 13 and rotate in the through hole 13. The outer shell 1 slides forward under the push of the transmission device 3 through the bracket 5, and the thrust is concentrated at the sharp corner of the triangular cone to lift and loosen the soil under the outer shell 1. The inclined part at the bottom of the outer shell 1 pushes the excavated soil, so that the soil accumulates on both sides of the outer shell 1 and is higher than the ground level, which makes it convenient for the rotating wheel 31 to rotate and fill the excavated trench.

[0053] like Figure 4 and Figure 5 As shown, a track 14 is installed on the upper end of the seedling rack 11. Arc-shaped hinge blocks 141 are linearly arrayed on the inner side of the track 14. A small spring 142 is engaged between the lower surface of the arc-shaped hinge block 141 and the track 14. A locking block 143 is fixedly installed at the connection between the arc-shaped hinge block 141 and the track 14. The locking block 143 is perpendicular to the track 14.

[0054] When the wheel 31 rotates, the track 14 rotates, causing the seedlings placed on the surface of the track 14 to move closer to the planters, which facilitates the seedling picking process during the planting work and improves the efficiency of banana seedling planting. When the track 14 rotates, the arc-shaped hinge block 141 is lifted up under the elastic force of the small spring 142. When the arc-shaped hinge block 141 is rotated under force, the locking block 143 locks the arc-shaped hinge block 141 so that the rotatable angle of the arc-shaped hinge block 141 is less than 90 degrees.

[0055] The upper end of the rectangular slider 34 is provided with a hook-shaped protrusion 341 on the side near the track 14, and the distance between the lower end of the hook-shaped protrusion 341 and the inner side of the track 14 is greater than the height of the locking block 143.

[0056] When the rotating wheel 31 drives the rectangular slider 34 to slide forward, the hook-shaped protrusion 341 hooks the arc-shaped hinge block 141 on the inner side of the track 14. Under the action of the thrust, the arc-shaped hinge block 141 rotates to the maximum angle, so that the arc-shaped hinge block 141 locks the hook-shaped protrusion 341 and drives the track 14 to rotate. When the rectangular slider 34 slides backward, the outer arc portion of the hook-shaped protrusion 341 slides in contact with the arc portion of the arc-shaped hinge block 141, so that the arc-shaped hinge block 141 rotates into the groove 371 on the inner side of the track 14, and the track 14 does not rotate, thus realizing the intermittent forward movement of the track 14.

[0057] like Figures 6 to 8 As shown, the lifting device 4 includes a lifting plate 41, a sliding bevel gear 42, a transmission bevel gear 43, a transmission rod 44, a connecting rod 45, and a clamping assembly 46. A T-shaped protrusion 412 is provided on one side of the lifting plate 41, and the T-shaped protrusion 412 is slidably connected to a T-shaped groove 15 inside the outer casing 1. A threaded hole 411 is provided on the lifting plate 41 to mate with the threaded rod 37. The sliding bevel gear 42 is rotatably connected to the lifting plate 41 and meshes with the transmission bevel gear 43. The eccentric position of the transmission bevel gear 43 is rotatably connected to one end of the transmission rod 44, and the other end of the transmission rod 44 is rotatably connected to one end of the connecting rod 45. The length of the connecting rod 45 is equal to the length from one end of the transmission rod 44 to the center of the transmission spur gear 36, and the other end of the connecting rod 45 is connected to the clamping assembly 46.

[0058] When the auxiliary planting equipment is working, the lifting device 4 slides, and the T-shaped protrusion 412 cooperates with the T-shaped groove 15 inside the outer shell 1 to limit the lifting plate 41, preventing the lifting plate 41 from getting stuck on the threaded rod 37 and rotating, thus affecting the lifting process of the lifting device 4, and driving the entire lifting device 4 to slide up and down stably inside the outer shell 1; the threaded hole 411 inside the lifting plate 41 cooperates with the threaded rod 37, so that the threaded rod 37 in the transmission device 3 rotates and drives the lifting plate 41 to slide up and down inside the outer shell 1. The up and down sliding of the lifting plate 41 drives the sliding bevel gear 42 and the transmission bevel gear 43 connected to it, as well as the clamping assembly 46, to slide up and down at the same time. When the sliding bevel gear 42 and the lifting plate 41 slide from the outside of the threaded rod 37 to the bottom of the inner side of the outer shell 1 and then slide to the top to form a cycle, the transmission bevel gear 43 rotates back and forth half a turn under the meshing drive of the sliding bevel gear 42, driving the connecting rod 45 to rotate 360°, and pulling the structure inside the clamping assembly 46 to rotate.

[0059] The lifting device 4 rises and falls when the transmission device 3 moves, so that the auxiliary planting equipment can plant banana seedlings while digging and filling the pit. During the planting process, the seedlings can be placed in the pit without the need for manual bending, which reduces the waste of human resources and improves the planting efficiency of banana seedlings.

[0060] like Figure 9 As shown, the sliding bevel gear 42 has a circular hole 421 at its center, the diameter of which is equal to the diameter of the threaded hole 411. A rectangular protrusion 422 is provided on the inner side of the circular hole 421, and a groove 371 that mates with the rectangular protrusion 422 is provided on the outer side of the threaded rod 37.

[0061] When the external force drives the transmission device 3 to move, the rotating wheel 31 drives the spur gear 36 to reciprocate through the rotating rod 32 and the connecting rod 33. The upper end of the threaded rod 37 is fixedly connected to the spur gear 36, thereby driving the threaded rod 37 to reciprocate. The threaded rod 37 is rotatably connected to the outer shell 1. The threaded rod 37 transmits the force received by the transmission device 3 to the lifting device 4 inside the outer shell 1. The sliding bevel gear 42 slides up and down with the lifting plate 41 on the outside of the threaded rod 37 through the round hole 421. The rectangular protrusion 422 on the inner side of the round hole 421 locks the groove 371 on the outside of the threaded rod 37. When the threaded rod 37 rotates, it drives the sliding bevel gear 42 to rotate synchronously with the threaded rod 37, transmitting the rotational kinetic energy of the threaded rod 37 to the transmission bevel gear 43, and finally realizing the transmission function of the transmission device 3.

[0062] An annular protrusion 423 is provided below the sliding bevel gear 42. The inner diameter of the annular protrusion 423 is larger than the diameter of the threaded rod 37. The lower end of the annular protrusion 423 is rotatably connected to the lifting plate 41.

[0063] When the lifting device 4 slides up and down inside the housing 1, the sliding bevel gear 42 slides up and down with the lifting plate 41 while rotating with the threaded rod 37, and the horizontal distance between the sliding bevel gear 42 and the lifting plate 41 remains unchanged, so that the sliding bevel gear 42 and the transmission bevel gear 43 remain engaged. The sliding bevel gear 42 drives the transmission bevel gear 43 to rotate, and transmits the rotational torque to the clamping assembly 46.

[0064] like Figure 3 As shown, the diameter and number of teeth of the sliding bevel gear 42 are the same as those of the spur gear 36, and the number of teeth of the transmission bevel gear 43 is twice the number of teeth of the transmission rack 35.

[0065] When the rotating wheel 31 rotates half a turn, it drives the transmission rack 35 to mesh with the spur gear 36. The spur gear 36 rotates from one end to the other on the transmission rack 35. The rotation of the spur gear 36 drives the threaded rod 37 to rotate, which in turn drives the sliding bevel gear 42 to rotate synchronously. This causes the sliding bevel gear 42 to slide to the bottom of the threaded rod 37. While sliding on the outside of the threaded rod 37, the sliding bevel gear 42 rotates synchronously with the threaded rod 37, driving the transmission bevel gear 43 to rotate half a turn. This causes one end of the transmission rod 44 to rotate half a turn at the eccentric position of the transmission bevel gear 43, and at the same time, it drives the connecting rod 45 to drive the structure in the clamping assembly 46 to rotate half a turn.

[0066] like Figure 8 and Figure 9 As shown, the clamping assembly 46 includes a toothed gear 461, a sliding rack 462, a pull rod 463, a fixing clamp 464, a slide rail 465, and a return spring 466. The center of the toothed gear 461 is fixedly connected to the other end of the connecting rod 45. The toothed portion of the toothed gear 461 is centrally symmetrical, and the toothed gear 461 meshes with the sliding rack 462. The sliding rack 462 is slidably connected to a rectangular slot 413 on the lifting plate 41. A rectangular protrusion 4621 is provided at one end of the sliding rack 462. One end of the pull rod 463 is symmetrically and rotatably mounted on the upper surface of the rectangular protrusion 4621. The other end of the pull rod 463 is connected to the fixing clamp 464. The fixing clamp 464 is slidably connected to the slide rail 465. The slide rail 465 is fixedly installed on one side of the lifting plate 41, and a return spring 466 is engaged between the slide rail 465 and the sliding rack 462.

[0067] The center of the toothed gear 461 is fixedly connected to the other end of the connecting rod 45, so that when the rotating wheel 31 rotates half a turn, the connecting rod 45 drives the toothed gear 461 to rotate half a turn; when the transmission bevel gear 43 reciprocates for one cycle, the toothed gear 461 rotates one turn; when the lifting device 4 slides to the bottom and top of the threaded rod 37, it meshes with the sliding rack 462 of the toothed gear 461, pushing the sliding rack 462 to slide in the rectangular groove 413. The rectangular protrusion 4621 of the sliding rack 462 compresses the return spring 466, causing the pull rod 463 to rotate and push the fixed bracket at the other end of the pull rod 463 to slide in the slide rail 465.

[0068] The clamping component 46 is designed so that when the lifting device 4 slides to the upper part of the inner shell 1, it releases the fixing clamp 464 to place the seedling, and when it slides to the lower part of the inner shell 1, it releases the seedling for planting. The planting depth can be controlled by clamping the seedling at different positions to prevent planting too deep and thus ensure the aeration of the root system. The fixing clamp 464 clamps the seedling to ensure that the planted banana seedling is perpendicular to the ground and prevents the seedling from tilting during planting, which would affect the growth process of the banana.

[0069] like Figure 9 As shown, a concave block 4641 is provided at one end of the fixing clip 464 near the slide rail 465, and the concave block 4641 is slidably connected to the square groove 4651 inside the slide rail 465.

[0070] The two ends of the concave block 4641 slide outside the square groove 4651 of the slide rail 465, limiting the movement of the fixed clamp 464. When the pull rod 463 pushes the fixed clamp 464, the concave block 4641 slides inside the slide rail 465, changing the distance between the two fixed clamps 464, so that the clamping assembly 46 is loosened to clamp and plant the seedling. When the sliding rack 462 is not engaged with the toothed gear 461, the return spring 466 pushes the pull rod 463 to make the concave block 4641 of the fixed clamp 464 slide to the inside of the square groove 4651 of the slide rail 465, thereby clamping the fixed clamp 464.

[0071] In the operation of this invention, the support 5 connects and fixes the transmission device 3 to the outer shell 1. After the outer shell 1 is manually pushed to dig the soil and form a trench, the rotating wheel 31 simultaneously pushes the soil lifted on both sides of the trench to fill and compact the trench. The transmission device 3 drives the track 14 to rotate through the sliding of the rectangular slider 34, pushing the seedling to be planted in front of the planter for easy access. At the same time, the transmission device 3 transmits the rotational torque of the rotating wheel 31 to the threaded rod 37 through the rotating rod 32, causing the threaded rod 37 to rotate and drive the lifting plate 41 to slide up and down, and drive the sliding bevel gear 42 to rotate synchronously with the threaded rod 37. When the clamping component 46 rises to the top with the lifting device 4, it clamps the banana seedling, and when it descends to the bottom, it releases the seedling, thus planting the seedling in the trench before filling it. The whole process does not require the planter to bend over and can dig holes and plant banana seedlings at the same time, which not only greatly reduces the waste of human resources, but also improves the planting efficiency of banana seedlings.
