Description

Technical Field

[0001] This invention relates to the field of vegetable seedling transplantation, specifically to a convenient transplanting device and method for greenhouse vegetable seedlings during their growth cycle. Background Technology

[0002] A greenhouse vegetable seedling transplanting device is a device or equipment specifically designed for transplanting vegetable seedlings in a greenhouse environment. This device aims to improve transplanting efficiency and accuracy, reduce the tediousness of manual operation, and may have automated or mechanized features. By using this device, farmers or horticultural workers can complete the transplanting of vegetable seedlings more quickly and conveniently, thereby increasing the growth rate and yield of crops.

[0003] Chinese patent CN216163354U discloses a white peony seedling transplanting device, including an L-shaped plate. An installation plate is fixedly connected to the top side of the L-shaped plate, and a U-shaped plate is set on the top of the installation plate. By setting an irregular rod, a swinging component, a limiting block, a placement shell, and a through groove, it is convenient to place the seedlings dug out through the placement shell. The swinging component is moved by rotating the irregular rod, and the placement shell is reciprocated under the limiting action of the slot through the rotational connection between the swinging component and the placement shell. This allows the soil covering the seedling roots and stems inside the placement shell to fall off, thereby ensuring the cleanliness of the seedling roots and stems during transplanting.

[0004] During the transplanting process, the seedling transplanting device of the above-mentioned patent will be clamped by the rotating plate and the mud-shoveling plate on both sides of the seedling. The clamping will cause the soil to squeeze the roots of the seedling, which can easily damage the roots of the seedling and affect the growth of the seedling after transplanting. Summary of the Invention

[0005] The purpose of this invention is to provide a convenient transplanting device and method for greenhouse vegetable seedlings during their growth cycle. By pressing the first grip handle and restricting the guide strip, the first and second main cutting blades can be simultaneously embedded into the soil. While embedded in the soil, they can also wrap around the lower end of the seedling, avoiding pinching the seedling and the soil at the lower end, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a convenient transplanting device for greenhouse vegetable seedlings during their growth cycle, comprising a protective shell, a support ring disposed in the middle of the upper end of the protective shell, an upper transmission rod disposed at the upper end of the support ring, a lower transmission rod disposed at the lower end of the support ring, one end of the lower transmission rod being rotatably connected to one end of the upper transmission rod, a first transmission plate disposed on one side of the lower end of the lower transmission rod, a second transmission plate disposed on the other side of the lower end of the lower transmission rod, a rotatable first main cutting plate disposed at the lower end of the outer side of the second transmission plate, a rotatable second main cutting plate disposed at the lower end of the outer side of the first transmission plate, and four first limiting strips disposed around the outer side of the lower transmission rod.

[0007] Preferably, sliding blocks are welded to both the front and rear ends of the first and second main cutting blades, and guide strips are provided on one side of the outer side of the two sliding blocks. The inside of the guide strips is connected to the outer sliding groove of the sliding blocks. The second transmission plate is rotatably connected to the upper end of the first main cutting blade, and the first transmission plate is rotatably connected to the upper end of the second main cutting blade.

[0008] Preferably, both the second and first transmission plates have movable transverse sliding rails located inside the lower transmission rod at the center position. The upper end of each transverse sliding rail has a sliding transmission block, and the outer side of the transmission block is slidably connected to the inner side of the transverse sliding rail. The transmission block at the upper outer end of the second transmission plate is welded and fixed to the lower end of the lower transmission rod, and the transmission block at the upper outer end of the first transmission plate is welded and fixed to the lower end of the lower transmission rod through a connecting frame, which is C-shaped.

[0009] Preferably, the first and second main cutting blades are provided with protective shells for support, and the protective shells are welded and fixed to the guide strips. The protective shells are provided with auxiliary cutting blades at both ends.

[0010] Preferably, the auxiliary cutting blade is rotatably connected to the outer wall of the protective shell, and a drive shaft for transmission is provided on the other side of the upper end of the protective shell, and the two ends of the drive shaft are respectively connected to the connection position between the auxiliary cutting blade and the protective shell through a drive belt.

[0011] Preferably, a second sector gear is welded to one side of the outer side of the transmission shaft, and the second sector gear is welded and fixed to the transmission shaft. A first sector gear is provided on one side of the outer side of the second sector gear, and the outer side of the first sector gear meshes with the outer side of the second sector gear. A motor for output is provided at the center position of one end of the first sector gear.

[0012] Preferably, a limiting cover is welded to the upper end of the support ring, a limiting disc is provided at the upper end of the upper transmission rod, and a first grip handle is welded to the upper end of the limiting disc.

[0013] Preferably, the inner side of the limiting cover is provided with four second limiting strips, which are welded and fixed to the limiting cover. A movable annular sliding rail is provided between two adjacent second limiting strips. An embedded cavity is provided on one side of the upper end of the annular sliding rail. The outer side of the limiting disc is provided with four limiting pieces.

[0014] Preferably, a second pressing sensor is provided on one side of the annular sliding rail, and a first pressing sensor is provided on the side of the annular sliding rail facing the embedding cavity. The first and second pressing sensors are electrically connected to the motor. After the limiting plate rotates and presses the second pressing sensor, it can give the motor a counterclockwise rotation start signal, so that the motor drives the secondary cutting blade to embed into the soil. After the limiting plate rotates and presses the first pressing sensor, it can give the motor a clockwise rotation start signal, so that the secondary cutting blade can be folded and retracted.

[0015] A transplanting method for a convenient transplanting device for greenhouse vegetable seedlings during their growth cycle includes the following steps:

[0016] Step 1: Place the lower end of the protective shell against the upper end of the soil and wrap it around the seedling to be transplanted. Turn it over and step on the pedal. The user presses the pedal with their foot to fix the protective shell in place.

[0017] Step 2: Press the first grip handle. The first grip handle drives the upper transmission rod to move longitudinally downward through the limiting disc. The upper transmission rod drives the transmission blocks on both sides of the lower end to move longitudinally through the lower transmission rod.

[0018] Step 3: The longitudinal downward movement of the transmission block can drive the second transmission plate and the first transmission plate to move longitudinally downward, and the second transmission plate and the first transmission plate will drive the first main cutting plate and the second main cutting plate to move longitudinally downward, respectively.

[0019] Step 4: After the first and second main cutting blades slide within the guide strip via the sliding block, the first and second main cutting blades rotate as they move downwards longitudinally.

[0020] Step 5: During the longitudinal movement of the limiting disc, the limiting piece will move longitudinally. The longitudinal movement of the limiting piece can be embedded in the annular sliding rail inside the limiting cover through the embedding cavity. The first grip can be driven by the limiting disc to rotate the limiting piece, so that the limiting piece is embedded in the second limiting strip on the side close to the second pressure sensor.

[0021] Step 6: After pressing the second pressing sensor, the second pressing sensor can give the motor a start signal. The output shaft of the motor can drive the first sector gear to rotate counterclockwise. The counterclockwise rotation of the first sector gear can drive the transmission shaft to rotate through the second sector gear. The transmission shaft can drive the secondary cutting blade to rotate through the transmission belt, so that the secondary cutting blade is embedded in the soil.

[0022] Step 7: The two auxiliary cutting blades, the first main cutting blade and the second main cutting blade can respectively wrap the soil around the lower end of the seedling. The seedling can be removed and transplanted directly by holding the first grip handle and the second grip handle.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. In this invention, the upper and lower transmission rods are pressed by the first grip handle. During the pressing process, due to the restriction and guidance of the guide strip, the sliding block can slide within the guide strip. Simultaneously, the first and second main cutting blades are embedded into the soil together. The lower end of the blades is rotated and embedded in the soil and wraps around the soil at the lower end of the seedling. This avoids the soil from being pinched and causing damage to the seedling roots. The soil is not squeezed, so the tightness of the soil does not change significantly during the transplanting process, adapting to the soil after transplanting.

[0025] 2. In this invention, the auxiliary cutting plates at both ends of the protective shell rotate with the transmission belt. When the first grip handle drives the limiting plate to rotate within the annular sliding rail via the limiting disc, it restricts the movement of the upper and lower transmission rods at the lower end. This restriction fixes the embedded state of the first and second main cutting plates, preventing slippage and soil loosening during seedling grabbing and soil movement for transplanting, thus improving stability. At the same time, the rotation of the limiting plate squeezes the second pressing sensor, which sends a start signal to the motor. The motor's output simultaneously drives the auxiliary cutting plates to rotate via the transmission belt. The rotation of the auxiliary cutting plates actively cuts the sides wrapped by the first and second main cutting plates. Through the two auxiliary cutting plates, the first and second main cutting plates, the soil and seedlings can be fully wrapped, improving the stability during seedling transplantation.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] To address the problem that existing seedling transplanting devices cause soil to compress the seedling roots during transplantation due to the clamping of seedlings by rotating plates and shovels, which can damage the roots and negatively impact seedling growth, this embodiment provides the following technical solution:

[0037] A convenient transplanting device for greenhouse vegetable seedlings during their growth cycle includes a protective shell 1. A second grip handle 6 is provided on one side of the outer side of the protective shell 1, and one side of the second grip handle 6 is welded and fixed to one side of the outer side of the protective shell 1. Grabbing the protective shell 1 by using the second grip handle 6 facilitates its movement and subsequent transplanting. Figure 1 As shown, a support ring 2 is provided in the middle of the upper end of the protective shell 1, and the lower end of the support ring 2 is welded and fixed to the middle position of the upper end of the protective shell 1. The support ring 2 facilitates the pressing and transmission of the upper end.

[0038] In this embodiment, an upper transmission rod 13 is provided at the upper end of the support ring 2, and a lower transmission rod 14 is provided at the lower end of the support ring 2. One end of the lower transmission rod 14 is rotatably connected to one end of the upper transmission rod 13. The lower transmission rod 14 can be pulled by the upper transmission rod 13, thereby adjusting the horizontal position of the lower first main cutting blade 16 and the second main cutting blade 18. Figure 1 , Figure 2 and Figure 3 As shown, the rotation between the upper transmission rod 13 and the lower transmission rod 14 ensures that the rotation of the upper transmission rod 13 will not affect the movement of the lower transmission rod 14.

[0039] In this embodiment, a first transmission plate 19 is provided on one side of the lower end of the lower transmission rod 14, and a second transmission plate 20 is provided on the other side of the lower end of the lower transmission rod 14. A rotatable first main cutting plate 16 is provided at the lower end of the outer side of the second transmission plate 20, and a rotatable second main cutting plate 18 is provided at the lower end of the outer side of the first transmission plate 19. Figure 4 As shown, the second transmission plate 20 and the first transmission plate 19 can be pressed by the lower transmission rod 14 to make the first main cutting plate 16 and the second main cutting plate 18 move longitudinally downward. The longitudinal downward movement can embed them into the soil, thus completing the transplanting of vegetable seedlings. Sliding blocks 24 are welded to both the front and rear ends of the first main cutting plate 16 and the second main cutting plate 18. Guide strips 17 are provided on one side of the outside of the two sliding blocks 24, and the inside of the guide strips 17 is connected to the sliding groove of the outside of the sliding blocks 24. Through the push of the lower transmission rod 14 and the guidance of the guide strips 17 to the sliding blocks 24, the first main cutting plate 16 can be rotated and embedded into the soil. The first main cutting plate 16 and the second main cutting plate 18 are wrapped around the lower end of the transplanting soil.

[0040] In this embodiment, the second transmission plate 20 is rotatably connected to the upper end of the first main cutting plate 16, and the first transmission plate 19 is rotatably connected to the upper end of the second main cutting plate 18, as shown below. Figure 4As shown, the interior of both the second transmission plate 20 and the first transmission plate 19 is provided with a movable transverse sliding rail 21 facing the middle position of the lower transmission rod 14. The upper end of the interior of the transverse sliding rail 21 is provided with a transmission block 22 for sliding, and the exterior of the transmission block 22 is slidably connected to the interior of the transverse sliding rail 21. During the process of the lower transmission rod 14 moving longitudinally downward to achieve pressing, the transmission block 22 will slide laterally in the transverse sliding rail 21 and continuously realize the transmission of the second transmission plate 20 and the first transmission plate 19.

[0041] In this embodiment, the transmission block 22 at the upper outer end of the second transmission plate 20 is welded and fixed to the lower end of the lower transmission rod 14, and the transmission block 22 at the upper outer outer end of the first transmission plate 19 is welded and fixed to the lower end of the lower transmission rod 14 through a connecting bracket 23. Figure 4 As shown, the connecting frame 23 is C-shaped. The connecting frame 23 ensures that after the second transmission plate 20 moves longitudinally and is restricted by the guide bar 17, the C-shaped connecting frame 23 will not restrict the lateral movement of the second transmission plate 20, thus avoiding the connecting frame 23 affecting the lateral movement of the second transmission plate 20.

[0042] In this embodiment, the first main cutting blade 16 and the second main cutting blade 18 are provided with a protective shell 1 for support, and the protective shell 1 is welded and fixed to the guide strip 17, such as... Figure 1 , Figure 2 and Figure 4 As shown, the protective shell 1 allows the first main cutting blade 16 and the second main cutting blade 18 to be fully housed inside the protective shell 1 after shrinking.

[0043] In this embodiment, secondary cutting blades 7 are provided at both the front and rear ends of the protective shell 1. The secondary cutting blades 7 are located on both sides between the first main cutting blade 16 and the second main cutting blade 18, such as... Figure 1 , Figure 4 and Figure 5 As shown, the secondary cutting blade 7 is rotatably connected to the outer wall of the protective shell 1. A transmission shaft 9 for transmission is provided on the other side of the upper end of the protective shell 1. The two ends of the transmission shaft 9 are respectively connected to the connection position between the secondary cutting blade 7 and the protective shell 1 through the transmission belt 10. The rotation of the position of the transmission shaft 9 can make the secondary cutting blade 7 rotate and embed itself into the soil. The secondary cutting blade 7, together with the first main cutting blade 16 and the second main cutting blade 18, can achieve complete wrapping of the soil, so as to avoid the soil and vegetable seedlings from loosening and falling off during the transplanting process.

[0044] In this embodiment, a second sector gear 30 is welded to one side of the outer side of the drive shaft 9, and the second sector gear 30 is welded and fixed to the drive shaft 9, such as... Figure 5 and Figure 7As shown, a first sector gear 29 is provided on one side of the second sector gear 30, and the outside of the first sector gear 29 is meshed with the outside of the second sector gear 30. A motor 8 for output is provided at the center of one end of the first sector gear 29. The output of the motor 8 can simultaneously drive the auxiliary cutting blades 7 at both ends of the protective shell 1 to rotate, so that the auxiliary cutting blades 7 are embedded in the soil along with the first main cutting blade 16 and the second main cutting blade 18.

[0045] In this embodiment, a limiting cover 3 is welded to the upper end of the support ring 2, and the limiting cover 3 is welded and fixed to the support ring 2. A limiting disc 11 is provided at the upper end of the upper transmission rod 13, and the limiting disc 11 is welded and fixed to the upper transmission rod 13. Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 8 As shown, a first grip handle 4 is welded to the upper end of the limiting disc 11. The first grip handle 4 can drive the lower limiting disc 11, the upper transmission rod 13 and the lower transmission rod 14 to move longitudinally. The first grip handle 4 can grip the limiting disc 11 to embed it into the limiting cover 3. The upper transmission rod 13 and the lower transmission rod 14 can be restricted when embedded in the limiting cover 3.

[0046] In this embodiment, four second limiting strips 25 are arranged around the inside of the limiting cover 3, such as... Figure 5 and Figure 6 As shown, the second limiting strip 25 is welded and fixed to the limiting cover 3. A movable annular sliding rail 26 is provided between two adjacent second limiting strips 25. An embedding cavity 5 is provided on one side of the upper end of the annular sliding rail 26. The annular sliding rail 26 can pass through the embedding cavity 5, penetrate the limiting cover 3 and be embedded to the outside. Four limiting pieces 12 are arranged around the outside of the limiting disk 11. After being driven by the limiting disk 11, the four limiting pieces 12 can be embedded into the annular sliding rail 26 through the embedding cavity 5. After being rotated, the embedded annular sliding rail 26 can be restricted by the limiting cover 3, thereby restricting and fixing the embedding positions of the lower first main cutting piece 16, the second main cutting piece 18 and the auxiliary cutting piece 7.

[0047] In this embodiment, 5 and Figure 6 As shown, a second pressing sensor 28 is provided on one side of the annular sliding rail 26, and a first pressing sensor 27 is provided on the side of the annular sliding rail 26 facing the embedding cavity 5. The first pressing sensor 27 and the second pressing sensor 28 are electrically connected to the motor 8 respectively. After the limiting piece 12 rotates and presses the second pressing sensor 28, it can give the motor 8 a counterclockwise rotation start signal, so that the motor 8 drives the sub-cutting piece 7 to embed into the soil. After the limiting piece 12 rotates and presses the first pressing sensor 27, it can give the motor 8 a clockwise rotation start signal, so that the sub-cutting piece 7 can be folded and retracted.

[0048] In this embodiment, four first limiting strips 15 are arranged around the outer periphery of the lower transmission rod 14, and the first limiting strips 15 are welded and fixed to the lower transmission rod 14, such as... Figure 2 , Figure 3 and Figure 4 As shown, the outer side of the first limiting bar 15 is connected to the lower end sliding groove inside the support ring 2. The first limiting bar 15 restricts the movement of the lower transmission rod 14, so that the lower transmission rod 14 can only move longitudinally back and forth and will not be transmitted due to the rotation of the upper transmission rod 13.

[0049] In this embodiment, as Figure 1 , Figure 5 and Figure 8 As shown, support frames 32 for support and transmission are provided on both sides of the outer shell 1. A foot pedal 31 is provided on one side of the outer shell 32, and the foot pedal 31 is rotatably connected to the support frame 32. The foot pedal 31 can be opened and closed by rotating inside the support frame 32. After the support frame 32 is opened, the user can step directly on the upper part of the support frame 32, which helps the secondary cutting blade 7, the first main cutting blade 16 and the second main cutting blade 18 to embed into the soil.

[0050] In this embodiment, as Figure 1 and Figure 8 As shown, an anti-slip strip 33 is horizontally provided at the upper end of the foot pedal 31 for anti-slip purposes, and the anti-slip strip 33 is bonded and fixed to the upper end of the foot pedal 31 with glue. The protruding foot pedal 31 can prevent slipping and falling off after stepping, thus improving the stability during the transplantation process.

[0051] A transplanting method for a convenient transplanting device for greenhouse vegetable seedlings during their growth cycle includes the following steps:

[0052] Step 1: Place the lower end of the outer shell 1 against the upper end of the soil and wrap it around the seedling to be transplanted. Turn the foot pedal 31 over so that the foot pedal 31 rotates within the support frame 32 and adheres to the soil. After adhering to the soil, the user presses the foot pedal 31 with their foot to fix the protective shell 1.

[0053] Step 2: Press the first grip handle 4. The first grip handle 4 drives the upper transmission rod 13 to move longitudinally downward through the limiting plate 11. The upper transmission rod 13 drives the transmission blocks 22 on both sides of the lower end to move longitudinally through the lower transmission rod 14.

[0054] Step 3: The longitudinal downward movement of the transmission block 22 can drive the second transmission plate 20 and the first transmission plate 19 to move longitudinally downward, and the second transmission plate 20 and the first transmission plate 19 will drive the first main cutting plate 16 and the second main cutting plate 18 to move longitudinally downward, respectively.

[0055] Step 4: After the first main cutting blade 16 and the second main cutting blade 18 slide within the guide bar 17 via the sliding block 24, the first main cutting blade 16 and the second main cutting blade 18 rotate during the longitudinal downward movement. This causes the lower ends of the first main cutting blade 16 and the second main cutting blade 18 outside the second transmission plate 20 and the first transmission plate 19, respectively, to rotate toward the middle position of the lower transmission rod 14, thus wrapping the lower end of the seedling to be transplanted.

[0056] Step 5: During the longitudinal movement of the limiting disc 11, the limiting piece 12 will move longitudinally. The longitudinal movement of the limiting piece 12 can be embedded in the annular sliding rail 26 inside the limiting cover 3 through the embedding cavity 5. The first grip handle 4 can be driven by the limiting disc 11 to rotate the limiting piece 12, so that the limiting piece 12 is embedded in the second limiting strip 25 on the side close to the second pressing sensor 28.

[0057] Step 6: After pressing the second pressing sensor 28, the second pressing sensor 28 can give the motor 8 a start signal. The output shaft of the motor 8 can drive the first sector gear 29 to rotate counterclockwise. The counterclockwise rotation of the first sector gear 29 can drive the transmission shaft 9 to rotate through the second sector gear 30. The transmission shaft 9 can drive the auxiliary cutting blade 7 to rotate through the transmission belt 10, so that the auxiliary cutting blade 7 is embedded in the soil.

[0058] Step 7: The two auxiliary cutting blades 7, the first main cutting blade 16 and the second main cutting blade 18 can respectively wrap the soil around the lower end of the seedling. The seedling can be removed and transplanted directly by holding the first grip handle 4 and the second grip handle 6.

The convenient transplanting device for greenhouse vegetable seedlings according to claim 1, characterized in that: The auxiliary cutting blade (7) is rotatably connected to the outer wall of the protective shell (1). A transmission shaft (9) for transmission is provided on the other side of the upper end of the protective shell (1), and the two ends of the transmission shaft (9) are respectively connected to the connection position between the auxiliary cutting blade (7) and the protective shell (1) by a transmission belt (10).

3. The convenient transplanting device for greenhouse vegetable seedlings during their growth cycle according to claim 2, characterized in that: A second sector gear (30) is welded to one side of the transmission shaft (9), and the second sector gear (30) is welded and fixed to the transmission shaft (9). A first sector gear (29) is provided on one side of the second sector gear (30), and the outside of the first sector gear (29) meshes with the outside of the second sector gear (30). A motor (8) for output is provided at the center of one end of the first sector gear (29).

4. A transplanting method based on the convenient transplanting device for the growth cycle of greenhouse vegetable seedlings as described in claim 3, characterized in that: Includes the following steps: Step 1: The lower end of the outer shell (1) is attached to the upper end of the soil and wrapped around the seedling to be transplanted. Turn over and step on the pedal (31). The user presses the pedal (31) with his foot to fix the protective shell (1). Step 2: Press the first grip handle (4). The first grip handle (4) drives the upper transmission rod (13) to move longitudinally downward through the limiting plate (11). The upper transmission rod (13) drives the transmission blocks (22) on both sides of the lower end to move longitudinally through the lower transmission rod (14). Step 3: The longitudinal downward movement of the transmission block (22) can drive the second transmission plate (20) and the first transmission plate (19) to move longitudinally downward respectively. The second transmission plate (20) and the first transmission plate (19) will drive the first main cutting plate (16) and the second main cutting plate (18) to move longitudinally downward respectively. Step 4: After the first main cutting blade (16) and the second main cutting blade (18) slide within the guide bar (17) via the sliding block (24), the first main cutting blade (16) and the second main cutting blade (18) rotate during the longitudinal downward movement. Step 5: During the longitudinal movement of the limiting disc (11), the limiting piece (12) will move longitudinally. The longitudinal movement of the limiting piece (12) can be embedded in the annular sliding rail (26) inside the limiting cover (3) through the embedding cavity (5). The first grip handle (4) can be driven by the limiting disc (11) to rotate the limiting piece (12), so that the limiting piece (12) is embedded in the second limiting strip (25) on the side close to the second pressing sensor (28). Step 6: After pressing the second pressing sensor (28), the second pressing sensor (28) can give the motor (8) a start signal. The output shaft of the motor (8) can drive the first sector gear (29) to rotate counterclockwise. The counterclockwise rotation of the first sector gear (29) can drive the transmission shaft (9) to rotate through the second sector gear (30). The transmission shaft (9) can drive the secondary cutting blade (7) to rotate through the transmission belt (10), so that the secondary cutting blade (7) is embedded in the soil. Step 7: The two secondary cutting blades (7), the first main cutting blade (16) and the second main cutting blade (18) can respectively wrap the soil around the lower end of the seedling. The seedling can be removed and transplanted directly by holding the first grip handle (4) and the second grip handle (6).
