Description

Technical Field

[0001] This utility model relates to the field of transplanting technology, and in particular to a plant transplanting device. Background Technology

[0002] Codonopsis pilosula, a rhizome-based traditional Chinese medicine, has a relatively long growth cycle, typically requiring 2 to 3 years before harvest. The process involves transplanting Codonopsis pilosula seedlings from nursery or direct seeding fields to the main field. This is a crucial step in Codonopsis pilosula cultivation, as transplanting shortens the growth cycle and improves yield and quality. Furthermore, transplanting allows for better management of water, fertilizer, and other factors, providing more favorable conditions for Codonopsis pilosula growth.

[0003] Traditional manual transplanting is not only time-consuming and labor-intensive, but also susceptible to variations in operator experience, making it difficult to ensure consistency in seedling placement angles and burial depths, thus significantly limiting the expansion of planting scale. To improve efficiency, some existing transplanting equipment has emerged, but significant shortcomings have been revealed in practical applications: the inability to flexibly adjust the placement height and tilt angle. Firstly, different batches of Codonopsis pilosula seedlings vary in length, and the soil looseness and trench depth of planting sites differ. Existing equipment often uses fixed placement pipes with no adjustable distance between the bottom and the trench, potentially causing longer seedlings to become stuck in the pipes due to insufficient height, affecting the continuity of transplanting. Secondly, Codonopsis pilosula transplanting requires a strict tilt angle (30°-45° to promote root development), but existing equipment uses fixed placement pipe angles, failing to meet the planting needs of different Codonopsis pilosula varieties and adapting to changes in slope. This often results in seedlings being placed vertically or with excessively large angle deviations, leading to decreased survival rates and uneven growth later on. Therefore, we propose a plant transplanting device to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a plant transplanting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A plant transplanting device includes a traction frame. Two fixed discs are fixedly connected to the top of the traction frame, and two tapered roller bearings are fixedly connected to the bottom of the traction frame. A drive shaft is fixedly connected to the inner ring of each of the two tapered roller bearings. A reduction motor is fixedly connected to the top of the traction frame. A driven sprocket is fixedly fitted onto the outer wall of each of the two drive shafts. A main sprocket is fixedly fitted onto the outer wall of the output shaft of the reduction motor. The outer walls of the main sprocket and the driven sprocket are meshed with the same chain. Multiple delivery cylinders are fixedly connected to the outer walls of both drive shafts. Corrugated pipes are fixedly connected to the bottom of each of the two fixed discs. A lower through-pipe is fixedly connected to the bottom of each of the two corrugated pipes. An adjustment component is provided on the outer wall of the lower through-pipe, and a telescopic tube is threaded onto the outer wall of the lower through-pipe.

[0007] Preferably, the adjusting assembly includes two threaded rods, and a T-shaped shaft is fixedly connected to the outer wall of each of the two lower tubes. One end of each threaded rod is fixedly connected to the outer wall of the two lower tubes. A fixing plate is fitted onto the outer wall of both the T-shaped shaft and the threaded rod. One end of the fixing plate is fixedly connected to the outer wall of the traction frame. A locking cap is threaded onto the outer wall of the threaded rod. When the locking cap is loosened, the lower tube can rotate around the T-shaped shaft to adjust the tilt angle.

[0008] Preferably, both the T-shaped shaft and the threaded rod are fitted with anti-loosening washers on their outer walls. The anti-loosening washers can increase friction and prevent the locking cap from loosening when the equipment vibrates.

[0009] Preferably, the outer wall of the traction frame is rotatably connected to two wheels.

[0010] Preferably, each of the two fixed disks has a through hole at its bottom, and the inner wall of the two through holes is rotatably connected to the outer wall of the two drive shafts respectively.

[0011] Preferably, the bottom of the traction frame is fixedly connected to four supports, and the bottom of each of the four supports is fixedly connected to a soil covering plate. As the device moves, the soil covering plate covers the Codonopsis pilosula seedlings in the planting ditch with soil, which can evenly cover the roots of the seedlings with soil.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution utilizes a telescopic tube design that allows for flexible adjustment of the distance between its bottom and the trench, perfectly adapting to the needs of different batches and lengths of Codonopsis pilosula seedlings. With the cooperation of a T-shaped shaft, fixing plate, anti-loosening pad, threaded rod, and locking cap, the tilt angle of the lower tube and telescopic tube can be easily adjusted to meet the tilt requirements for Codonopsis pilosula transplanting. It can also adapt to the planting needs of different varieties of Codonopsis pilosula and changes in plot slope, effectively solving the problem of seedlings being placed vertically or having excessive angle deviation due to fixed angles in existing equipment. Furthermore, the continuous operation of multiple delivery tubes improves transplanting efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1-5As shown, a plant transplanting device is disclosed, including a traction frame 1. The traction frame 1 is connected to traction equipment such as a tractor to realize the overall movement of the device. A seat is added to the traction frame 1, which is located above the reduction motor 6. Two wheels 2 are rotatably connected to the outer wall of the traction frame 1. Two fixed discs 3 are fixedly connected to the top of the traction frame 1. Two tapered roller bearings are fixedly connected to the bottom of the traction frame 1. The inner rings of the two tapered roller bearings are fixedly connected to a drive shaft 16. The tapered roller bearings can effectively reduce the frictional resistance when the drive shaft 16 rotates, improve the rotational efficiency of the drive shaft 16, and bear radial and axial loads at the same time, ensuring the stability of the drive shaft 16 when driving the delivery cylinder 7, and extending the service life of the equipment.

[0023] A geared motor 6 is fixedly connected to the top of the traction frame 1. The main sprocket on the output shaft of the geared motor 6 drives the driven sprocket 4 to rotate through the chain 5, providing power for the entire transmission system. The outer walls of the two transmission shafts 16 are fixedly fitted with driven sprockets 4, and the outer walls of the output shaft of the geared motor 6 are fixedly fitted with main sprockets. The outer walls of the main sprockets and the outer walls of the driven sprockets 4 are meshed with the same chain 5.

[0024] Multiple delivery cylinders 7 are fixedly connected to the outer walls of the two drive shafts 16. When the multiple delivery cylinders 7 rotate with the drive shafts 16, they can carry Codonopsis pilosula seedlings and accurately put the seedlings into the corrugated pipe 10 when they rotate to the top of the corrugated pipe 10. The bottom of the two fixed plates 3 is provided with through holes, and the inner walls of the two through holes are rotatably connected to the outer walls of the two drive shafts 16 respectively.

[0025] Four supports 8 are fixedly connected to the bottom of the traction frame 1. Soil covering plates 9 are fixedly connected to the bottom of each of the four supports 8. As the device moves, the soil covering plates 9 cover the Codonopsis seedlings in the planting ditch with soil, which can evenly cover the roots of the seedlings. Corrugated pipes 10 are fixedly connected to the bottom of each of the two fixed plates 3. Lower pipes 14 are fixedly connected to the bottom of each of the two corrugated pipes 10. A telescopic pipe 15 is threaded on the outer wall of the lower pipe 14.

[0026] The outer wall of the lower tube 14 is provided with an adjustment assembly, which includes two threaded rods 17. The threaded rods 17, in conjunction with the locking cap 13, can fix the angle of the lower tube 14. When the locking cap 13 is loosened, the lower tube 14 can rotate around the T-shaped shaft 12 to adjust the tilt angle.

[0027] T-shaped shafts 12 are fixedly connected to the outer walls of the two lower tubes 14. When the tilt angle of the lower tubes 14 is adjusted, the T-shaped shafts 12 rotate within the fixed plate 11 to ensure the stability of the angle adjustment process. One end of each of the two threaded rods 17 is fixedly connected to the outer wall of the two lower tubes 14.

[0028] Both the T-shaped shaft 12 and the threaded rod 17 are fitted with fixing plates 11. One end of the fixing plate 11 is fixedly connected to the outer wall of the traction frame 1. The fixing plate 11 provides an installation support point for the lower pipe 14 and the adjustment assembly. The outer wall of the threaded rod 17 is threaded with a locking cap 13. Both the T-shaped shaft 12 and the threaded rod 17 are fitted with anti-loosening washers. The anti-loosening washers can increase friction and prevent the locking cap 13 from loosening when the equipment vibrates, further ensuring the reliability of the angle fixation of the lower pipe 14.

[0029] Working principle: In use, the traction frame 1 is connected to existing traction equipment (such as a tractor). The traction equipment drives the traction frame 1 and the two wheels 2 to move. During transplanting, multiple Codonopsis pilosula seedlings are placed into multiple delivery cylinders 7 in sequence. As the reduction motor 6 operates, it drives the two main sprockets connected to it to rotate. The rotation of the two main sprockets drives the two chains 5 to rotate, thereby causing the two driven sprockets 4 to rotate. The rotation of the two driven sprockets 4 drives the two drive shafts 16 to rotate, and the rotation of the two drive shafts 16 drives the multiple delivery cylinders 7 to rotate. When the Codonopsis pilosula in the delivery cylinder 7 is at the top of the corrugated pipe 10... After falling, it falls into the corrugated pipe 10, and continues to fall into the lower pipe 14 and the telescopic pipe 15 along the corrugated pipe 10, and finally falls into the pre-dug trench. At the same time, when placing different batches of Codonopsis pilosula of different lengths, the two lower pipes 14 are rotated to move the two telescopic pipes 15 up and down, and the distance between the bottom of the telescopic pipe 15 and the trench is adjusted to meet the placement requirements. For vertical or oblique placement requirements, the two locking caps 13 can be rotated to release the position fixation of the two lower pipes 14. The two lower pipes 14 are rotated through the T-shaped shaft 12 and the threaded rod 17 to adjust the tilt angle of the telescopic pipe 15 and the lower pipe 14.

[0030] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the geared motor 6 to facilitate the control of the overall operation.
