Abstract
Description
Technical Field
[0001] This utility model relates to the field of transplanting device technology, and in particular to a flower seedling cultivation and transplanting device. Background Technology
[0002] As an important industry with both ornamental and economic value, the seedling cultivation and transplanting process directly affects the quality and yield of flowers. In the early days, flower cultivation was small-scale, mainly consisting of home gardening or small-scale flower growers. The cultivation and transplanting of flower seedlings relied entirely on manual labor. People used simple tools such as small shovels and watering cans to plant seeds or seedlings in simple flowerpots and wooden boxes. When transplanting, they could only carefully dig out each seedling one by one with a shovel and then transplant them to the new planting area.
[0003] However, traditional equipment and transplanting methods cannot achieve mass transfer of seedlings, requiring individual handling of each seedling, which consumes a lot of manpower and time. Moreover, traditional equipment lacks measures to secure the seedlings, making them prone to shaking and tipping over during handling and transplanting, further increasing the risk of seedling damage, which needs to be improved. Utility Model Content
[0004] The purpose of this utility model is to solve the technical problems mentioned in the background section.
[0005] The present invention adopts the following technical solution:
[0006] A seedling transplanting device includes a transplanting plate, a handle fixedly installed at the top of the transplanting plate, a water injection pipe fixedly installed at the top of the transplanting plate, a first closing cover rotatably connected to the surface of the water injection pipe, a drain pipe fixedly installed at the bottom of the transplanting plate, a second closing cover rotatably connected to the surface of the drain pipe, an insertion groove formed on the top surface of the transplanting plate, a placement groove formed inside the transplanting plate, a transplanting cylinder fitted inside the insertion groove, a fixing plate fixedly installed at the top of the transplanting plate, a moving groove formed on the top surface of the fixing plate, a rotating plate fitted inside the moving groove, an arc-shaped groove formed on the surface of the rotating plate, a moving rod fitted inside the arc-shaped groove and the moving groove, a clamping block fixedly installed on the top surface of the moving rod, a sliding groove formed on the surface of the fixing plate, a rotating lever fitted inside the sliding groove, an arc-shaped rod fixedly installed on the surface of the rotating lever, a ring spring fitted on the outer surface of the arc-shaped rod, and a fixing frame fixedly installed at the top of the transplanting plate.
[0007] According to a preferred embodiment, the other end of the arc-shaped rod is sleeved inside the fixed frame, one end of the first annular spring is connected and fixed to the surface of the rotating block, and the other end of the first annular spring is connected and fixed to the surface of the fixed frame. Here, one end of the arc-shaped rod is sleeved inside the fixed frame, and the other end is connected to the rotating block, forming a stable transmission connection to ensure that the movement of the rotating block can be accurately transmitted to the clamping mechanism.
[0008] According to a preferred embodiment, the bottom end of the insertion groove penetrates the top end of the placement groove, and the top end of the drain pipe and the bottom end of the water injection pipe are both connected to the placement groove. The handles are in two sets and symmetrically distributed on the top surface of the transplanting board. Here, the insertion groove and the placement groove are connected, allowing the transplanting cylinder and the placement groove to communicate, facilitating water flow between them and meeting the seedling roots' need for water absorption.
[0009] According to a preferred embodiment, the first annular spring is initially in a semi-compressed state, the surface of the clamping block is arc-shaped, and the surface of the clamping block is in close contact with the surface of the transplanting cylinder. Here, the first annular spring in the semi-compressed state provides a continuous elastic force to the clamping mechanism, ensuring that the clamping block can closely fit the surface of the transplanting cylinder, firmly clamping the transplanting cylinder and preventing it from falling or shifting during handling and transplanting.
[0010] According to a preferred embodiment, the insertion slots, transplanting cylinders, and fixing plates are arranged in multiple sets, forming an array on the top and surface of the transplanting plate. The top shape of the moving slot and the shape of the arc-shaped slot are both flattened ellipses. One end of the rotating block is connected and fixed to the side surface of the rotating plate. Here, the multiple arrayed insertion slots, transplanting cylinders, and fixing plates allow for the simultaneous cultivation and transplanting of multiple flower seedlings, significantly improving work efficiency and meeting the needs of large-scale flower cultivation and transplanting.
[0011] According to a preferred embodiment, the bottom end of the transplanting cylinder has a slot, and a plug is inserted into the slot. A base plate is fixedly installed at the bottom end of the plug. A fixing groove is formed on the top surface of the base plate, and a spring is sleeved inside the fixing groove. The bottom end of the transplanting cylinder has a fixing groove, and an arc-shaped block is sleeved inside both the fixing groove and the fixing groove. Here, the slot and plug at the bottom end of the transplanting cylinder cooperate to facilitate the quick installation and removal of the transplanting cylinder and the base plate. When transplanting seedlings, the transplanting cylinder can be inserted into the soil and the base plate can be separated for easy operation.
[0012] According to a preferred embodiment, one end of the second spring is connected and fixed to the bottom surface of the arc-shaped block, and the other end of the second spring is connected and fixed to the inner surface of the first fixing groove. Multiple sets of the second spring, the first fixing groove, the second fixing groove, and the arc-shaped block are arranged circumferentially on the bottom surface of the transplanting cylinder and the top surface of the base plate. Here, the multiple sets of circumferentially distributed second springs, first fixing grooves, second fixing grooves, and arc-shaped blocks provide a uniform and symmetrical fastening force to the transplanting cylinder and the base plate, ensuring balanced force at the connection points and preventing loosening due to excessive or insufficient local force.
[0013] According to a preferred embodiment, both the insert and the slot are L-shaped with an arc. The transplanting cylinder is composed of four sets of arc-shaped closed plates joined together. There are four sets of slots and inserts, arranged circumferentially at the top of the base plate and the bottom of the closed plates. Water-permeable grooves are formed through the closed plates near their bottom and on the surface of the base plate. Here, the L-shaped inserts and slots with arcs ensure connection strength while facilitating quick insertion and removal, thus improving installation and disassembly efficiency.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0029] Example 1
[0030] Please see Figures 1-5 This utility model provides a technical solution:
[0031] A seedling transplanting device includes a transplanting plate 1, a handle 2 fixedly installed at the top of the transplanting plate 1, a water injection pipe 3 fixedly installed at the top of the transplanting plate 1, a closing cover 4 rotatably connected to the surface of the water injection pipe 3, a drain pipe 5 fixedly installed at the bottom of the transplanting plate 1, a closing cover 6 rotatably connected to the surface of the drain pipe 5, an insertion groove 7 formed on the top surface of the transplanting plate 1, a placement groove 8 formed inside the transplanting plate 1, a transplanting cylinder 9 fitted inside the insertion groove 7, a fixing plate 10 fixedly installed at the top of the transplanting plate 1, a moving groove 11 formed on the top surface of the fixing plate 10, and a rotating plate 12 fitted inside the moving groove 11. The rotating plate 12 has an arc-shaped groove 13 on its surface. A moving rod 14 is fitted inside the arc-shaped groove 13 and the moving groove 11. A clamping block 15 is fixedly installed on the top surface of the moving rod 14. The fixed plate 10 has a sliding groove 16 on its surface. A rotating lever 17 is fitted inside the sliding groove 16. An arc-shaped rod 18 is fixedly installed on the surface of the rotating lever 17. A ring spring 19 is fitted on the outer surface of the arc-shaped rod 18. A fixing frame 20 is fixedly installed on the top of the transplanting plate 1. When using the flower seedling cultivation and transplanting device, the transplanting cylinder 9 is first inserted into the insertion groove 7 at the top of the transplanting plate 1. Positioning is completed by the cooperation between the insertion groove 7 and the transplanting cylinder 9. Then, the operator holds the handle 2 with both hands and opens the closing cover 4 on the surface of the water injection pipe 3 according to the cultivation needs. Water is injected into the placement groove 8 inside the transplanting plate 1 through the water injection pipe 3. The water permeates into the transplanting cylinder 9 through the placement groove 8 to provide water for the flower seedlings. After watering is completed, the closing cover 4 is closed. To drain excess water, open the second closed cover 6 on the surface of the drain pipe 5 to drain the water from the placement trough 8. After draining, close the second closed cover 6. When it is necessary to fix the transplanting cylinder 9, move the rotating block 17 in the sliding groove 16 on the surface of the fixing plate 10. The rotating block 17 drives the arc rod 18 to move within the fixing frame 20, while simultaneously stretching the ring spring 19. When the rotating block 17 rotates, it drives the rotating plate 12 connected to it to rotate within the moving groove 11. The arc groove 13 on the surface of the rotating plate 12 causes the moving rod 14 to move within the moving groove 11 and the arc groove 13, thereby pushing the clamping block 15 at the top of the moving rod 14 towards the transplanting cylinder 9 until the clamping block 15 is tightly attached to the surface of the transplanting cylinder 9, firmly clamping it for subsequent cultivation and transplanting operations.
[0032] Please see Figures 1-6The other end of the arc-shaped rod 18 is fitted inside the fixing frame 20. One end of the ring spring 19 is connected and fixed to the surface of the rotating block 17, and the other end of the ring spring 19 is connected and fixed to the surface of the fixing frame 20. The bottom end of the insertion slot 7 passes through the top end of the placement slot 8. The top end of the drain pipe 5 and the bottom end of the water injection pipe 3 are both connected to the placement slot 8. There are two sets of handles 2, which are symmetrically distributed on the top surface of the transplanting plate 1. The ring spring 19 is initially in a semi-compressed state. The surface of the clamping block 15 is arc-shaped and is in close contact with the surface of the transplanting cylinder 9. There are multiple sets of insertion slots 7, transplanting cylinder 9, and fixing plates 10, which are arrayed on the top end and surface of the transplanting plate 1. The top shape of the moving slot 11 and the shape of the arc-shaped slot 13 are both flat elliptical. One end of the rotating block 17 is connected to the side end of the rotating plate 12. The surfaces are connected and fixed. One end of spring 25 is connected and fixed to the bottom surface of arc block 27, and the other end of spring 25 is connected and fixed to the inner surface of fixing groove 24. There are multiple sets of spring 25, fixing groove 24, fixing groove 26, and arc block 27, which are distributed in a circle on the bottom surface of transplanting cylinder 9 and the top surface of base plate 23. The shape of insert 22 and slot 21 is an "L" shape with an arc. Transplanting cylinder 9 is spliced by four sets of arc-shaped closed plates. There are four sets of slot 21 and insert 22, which are distributed in a circle on the top of base plate 23 and the bottom of closed plates. Water permeable grooves are opened through the closed plates near the bottom and on the surface of base plate 23. Transplanting cylinder 9 is spliced by four sets of arc-shaped closed plates. With the circumferentially distributed slot 21 and insert 22, the transplanting cylinder 9 is easier to assemble and disassemble, and its size can be adjusted according to actual needs. The permeable trough design ensures that water can smoothly penetrate to the roots of the seedlings while avoiding waterlogging, ensuring that the seedling roots are in a good growing environment, promoting healthy seedling growth, and improving the success rate of transplanting flower seedlings.
[0033] Example 2
[0034] Please see Figures 4-6The bottom of the transplanting cylinder 9 has a slot 21, and a plug 22 is inserted into the slot 21. A base plate 23 is fixedly installed at the bottom of the plug 22. A fixing groove 24 is formed on the top surface of the base plate 23. A spring 25 is fitted inside the fixing groove 24. The bottom of the transplanting cylinder 9 has a fixing groove 26. An arc-shaped block 27 is fitted inside the fixing groove 24 and the fixing groove 26. When assembling the transplanting cylinder 9 part of the flower seedling cultivation and transplanting device, first align the plug 22 with the slot 21 at the bottom of the transplanting cylinder 9, and then rotate the closing plate. The rotation of the closing plate drives the plug 22 to be inserted into the slot 21, so that the base plate 23 is initially connected to the transplanting cylinder 9. At this time, the spring 25 in the fixing groove 24 at the top of the base plate 23 is in a compressed state. The spring 25 pushes the arc-shaped block 27, so that part of it is stuck into the fixing groove 26 at the bottom of the transplanting cylinder 9. Under the elastic force of spring 25, the arc-shaped block 27 is tightly locked between the first fixing groove 24 and the second fixing groove 26, firmly connecting the transplanting cylinder 9 to the base plate 23, ensuring that the transplanting cylinder 9 and the base plate 23 will not easily separate during the seedling cultivation process. When it is necessary to transplant the seedlings, rotate the base plate 23. The rotation of the base plate 23 drives the slider to move, and at the same time, the arc-shaped block 27 is squeezed, overcoming the elastic force of spring 25, and exits from the second fixing groove 26. In addition, the slider disengages from the sliding groove 16. At this time, the transplanting cylinder 9 can be easily separated from the base plate 23, making it convenient to insert the transplanting cylinder 9 into the soil for seedling transplanting.
[0035] Working Principle: When using the flower seedling cultivation and transplanting device, first insert the transplanting cylinder 9 into the insertion slot 7 at the top of the transplanting plate 1. The insertion slot 7 and the transplanting cylinder 9 are positioned by their cooperation. Then, the operator holds the handle 2 with both hands and opens the closing cover 4 on the surface of the water injection pipe 3 according to the cultivation needs. Water is injected into the placement slot 8 inside the transplanting plate 1 through the water injection pipe 3. The water seeps into the transplanting cylinder 9 through the placement slot 8, providing moisture for the flower seedlings. After watering, the closing cover 4 is closed. If excess water needs to be drained, the closing cover 6 on the surface of the drain pipe 5 is opened to drain the water in the placement slot 8. After draining, the closing cover 6 is closed. When it is necessary to fix the transplanting cylinder 9, the rotating block 17 in the sliding groove 16 on the surface of the fixing plate 10 is moved. The rotating block 17 drives the arc rod 18 to move within the fixing frame 20, while stretching the ring spring 19. When the rotating lever 17 rotates, it drives the rotating plate 12 connected to it to rotate within the moving groove 11. The arc-shaped groove 13 on the surface of the rotating plate 12 causes the moving rod 14 to move within the moving groove 11 and the arc-shaped groove 13, thereby pushing the clamping block 15 at the top of the moving rod 14 to move towards the transplanting cylinder 9 until the clamping block 15 is tightly attached to the surface of the transplanting cylinder 9, firmly clamping it for subsequent cultivation and transplanting operations. When assembling the transplanting cylinder 9 part of the flower seedling cultivation and transplanting device, first align the insert 22 with the slot 21 at the bottom of the transplanting cylinder 9, then rotate the closing plate. The rotation of the closing plate drives the insert 22 to be inserted into the slot 21, so that the bottom plate 23 is initially connected to the transplanting cylinder 9. At this time, the spring 25 in the first fixing groove 24 at the top of the bottom plate 23 is in a compressed state. The spring 25 pushes the arc-shaped block 27, causing part of it to be inserted into the second fixing groove 26 at the bottom of the transplanting cylinder 9. Under the elastic force of spring 25, the arc-shaped block 27 is tightly locked between the first fixing groove 24 and the second fixing groove 26, firmly connecting the transplanting cylinder 9 to the base plate 23, ensuring that the transplanting cylinder 9 and the base plate 23 will not easily separate during the seedling cultivation process. When it is necessary to transplant the seedlings, rotate the base plate 23. The rotation of the base plate 23 drives the slider to move, and at the same time, the arc-shaped block 27 is squeezed, overcoming the elastic force of spring 25, and exits from the second fixing groove 26. In addition, the slider disengages from the sliding groove 16. At this time, the transplanting cylinder 9 can be easily separated from the base plate 23, making it convenient to insert the transplanting cylinder 9 into the soil for seedling transplanting.
[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
