Description

Technical Field

[0001] This utility model relates to a seedling transplanter, and more specifically, a portable seedling transplanter. Background Technology

[0002] Traditional seedling transplanting requires steps such as digging holes, burying the seedlings, breaking the plastic film, removing the seedlings, and building a dam. To solve this problem, existing technology uses a portable seedling transplanter that integrates these steps into one operation by inserting the transplanter into the soil through a cylindrical structure.

[0003] Portable seedling transplanters are typically operated by two-handed handles and have a longitudinally extending structure with the cylinder at the bottom. The cylinder is inserted into the soil, and when pulled out, it carries the soil and the seedling within. Due to soil moisture issues, insertion resistance is greater when the soil is dry, and because the contact area between the cylinder and the soil is larger. Furthermore, the cylinder cannot avoid locations with stones in the soil. This is because the position of the cylinder is fixed, and the position of the seedling is also fixed; avoiding these stones would prevent the seedling from being centered within the cylinder, and misalignment during operation can easily damage the roots or leaves of the seedling. Utility Model Content

[0004] This invention provides a portable transplanter, the purpose of which is to reduce the resistance when inserting seedlings into the soil.

[0005] The above objectives are achieved through the following technical solutions:

[0006] A portable seedling transplanter includes a frame with at least two circumferentially distributed shovels inserted into the frame, allowing the shovels to move longitudinally relative to the frame. Each shovel has a shovel head fixed to its top, which can rest against the lower part of the frame.

[0007] The frame includes a main rod, a support fixed to the lower end of the main rod, a first connector fixed to the lower end of the support, and a ring plate fixed to the lower end of the first connector. The ring plate has a number of limiting holes evenly distributed around its circumference, the same as the number of shovel plates. The shovel plates can be inserted into the limiting holes, and the limiting holes allow the shovel plates to move only longitudinally.

[0008] The first connector is an L-shaped structure in the form of a rod or tube.

[0009] The number of the first connectors is three to four, and they are evenly distributed in the circumferential direction.

[0010] It also includes a handle assembly, which includes a connecting frame. The connecting frame has the same number of second connecting pieces as the number of shovels fixed to it. A ring-shaped handle is provided above the connecting frame. All the second connecting pieces are fixed to the ring-shaped handle. The connecting frame is fitted onto the main rod, so that the connecting frame can rotate or move longitudinally around the axis of the main rod. Each shovel head can have a second connecting piece directly above it, and the second connecting pieces can also be offset from the shovel head.

[0011] The main rod has a hole through which the positioning rod passes. The length of the positioning rod is less than the inner diameter of the ring handle. One end of the positioning rod is located inside the main rod, and the other end of the positioning rod is locked at the top of the ring handle.

[0012] The friction between the outer surface of the positioning rod and the main rod can provide temporary fixation.

[0013] One end of a rope is fixed to each shovel head, and the other end of the rope is fixed to the connecting frame.

[0014] A rod-shaped handle is fixed to the top of the main rod, and the rod-shaped handle is located inside the cylindrical surface where the ring-shaped handle is located.

[0015] The number of limit ports is three or four.

[0016] The beneficial effects of this portable seedling transplanter are as follows:

[0017] The existing integrated cylindrical structure has been replaced with multiple shovels, making it easier for a single shovel to be inserted into the soil and reducing resistance, making it suitable for use when the soil is dry. When the soil is moist, the dual-handle operation mode of the handle assembly allows all shovels to be inserted into the soil simultaneously, providing the functionality of a conventional portable seedling transplanter. Lifting the handle assembly also helps to unload the soil from the shovels. If one shovel encounters resistance during descent, it can be removed from the limiting slot and inserted into a new location nearby, offset from any fixed object in the soil.

[0026] A portable seedling transplanter, including a frame, combined with Figures 1 to 2 The frame includes a main rod 1 made of metal, a support 2, a first connector 3, and a ring plate 4;

[0027] Specifically, the lower end of the main rod 1 is fixedly connected to a support 2. The support 2 protrudes laterally from the main rod 1. The lower end of the support 2 is fixedly connected to a first connecting member 3, and the lower end of the first connecting member 3 is fixedly connected to a ring disc 4. The first connecting member 3 is preferably a metal rod or tubular structure, which is easy to be bent into an L-shape. The number of first connecting members 3 is preferably three to four, and they are evenly distributed in the circumferential direction. The connection method at both ends of the first connecting member 3 is preferably welding. Figure 3 and 4 At least two limiting ports 5 are evenly distributed around the circumference of the ring disk 4, preferably four limiting ports 5.

[0028] To further explain, in combination Figure 5 and 7 A shovel plate 7 is inserted into each limiting port 5, allowing the shovel plate 7 to move longitudinally along the limiting port 5, with all shovel plates 7 located on a virtual circle. A shovel plate head 8 is fixed to the top of each shovel plate 7, and the function of the shovel plate head 8 is to abut against the top of the ring plate 4 and to be gripped or stepped on by the user.

[0029] During operation, you can first insert a shovel 7 into the limiting port 5, step on the shovel head 8 of the shovel 7 with your foot, and hold the main rod 1 with your hand to shovel the shovel 7 into the soil. Then add shovels 7 to other limiting ports 5 until four shovels 7 are inserted.

[0030] The above solution is a necessary technical solution, aiming to change the existing integrated cylindrical structure into multiple shovels 7, thereby facilitating the insertion of a single shovel 7 into the soil, suitable for use when the soil is dry. This avoids the large contact area between the integrated structure and the ground surface, which would otherwise make insertion into the soil difficult.

[0031] The above solutions are designed to support a wider range of protection. In actual products, based on the necessary technical solutions described above, the following optimized embodiments are implemented:

[0032] Example 1: A handle for gripping is fixed to the top of the main rod 1. The shape of the handle is not limited to rod shape, but can also be flower shape or disc shape, etc., preferably rod shape.

[0033] Example 2: Features a set of handle components, combined with... Figure 6The handle assembly includes a connecting frame 9. When there are four shovel plates 7, the connecting frame 9 has a cross structure. The support 2 can support the connecting frame 9. Each of the four ends of the connecting frame 9 is fixed with a second connecting member 10. The top of the second connecting member 10 is higher than the connecting frame 9, and the bottom of the second connecting member 10 is lower than the connecting frame 9. All four second connecting members 10 are fixed to the ring handle 11. The connecting frame 9 is fitted onto the main rod 1 by plugging it in. When the four shovel plates 7 are respectively inserted into the four limiting ports 5, the four second connecting members 10 can be located directly above the four shovel plate heads 8. For relatively moist soil, the shovel plates 7 are easy to insert into the soil, so the main rod 1 can be gripped with one hand. The main rod 1 can control the position of the ring disc 4, which is used to control the position of the shovel plates 7. With the other hand, grasp the ring handle 11. Press down the ring handle 11 so that the four blade heads 8 are held in place by the four second connectors 10, restricting the upward freedom of the blades 7 relative to the ring disc 4. Push the main rod 1 and the ring handle 11 downward so that all blades 7 are inserted into the soil simultaneously.

[0034] Further optimization of Embodiment 2: A horizontal hole is provided on the main rod 1, through which the positioning rod 12 passes. The friction between the outer surface of the positioning rod 12 and the main rod 1 provides temporary fixation. The length of the positioning rod 12 is less than the inner diameter of the ring handle 11. One end of the positioning rod 12 is located inside the main rod 1, and the other end is engaged with the top of the ring handle 11. At this time, the second connecting piece 10 also abuts against the top of the corresponding shovel head 8, reducing the force required by one hand and lowering the difficulty of operation. This solution allows the present application to have the functions of a conventional portable seedling transplanter while retaining the inventive points of the present application.

[0035] In this embodiment, when the invention point needs to be used, the ring handle 11 can be rotated to make the ring handle 11 drive the second connecting member 10 to make a circular motion around the main rod 1 until the second connecting member 10 is separated from the shovel head 8. The second connecting member 10 is misaligned with the shovel head 8, so that the degree of freedom above the single shovel 7 is no longer restricted, and the shovel 7 can be taken out from the limiting port 5 and used freely.

[0036] Example 3: Each spatula head 8 is provided with an opening for fingers to pass through or grip.

[0037] Example 4: One end of a rope 13 is fixed to each shovel head 8. The other end of the rope 13 can be fixed to the connecting frame 9 using adhesive tape or / and screws, or tied to a through hole in the connecting frame 9. This way, when using a single shovel 7, the other shovel heads 8 remain suspended without additional management. Based on Example 3, the rope 13 can be passed through the opening and secured to the shovel head 8. Furthermore, due to the addition of the rope 13, to lift all the shovel heads 7, simply lift the ring handle 11.

[0038] Example 5: Based on Example 4, a lever ring 6 is fixed to the inner wall of the ring plate 4. When all the shovel plates 7 are lifted by the rope 13, all the shovel plates 7 carry soil, the soil carries seedlings, and the seedlings are located at the opening in the center of the lever ring 6. The lever ring 6 restricts the soil from rising further. Therefore, the soil descends relative to the shovel plates 7 during the process of lifting the shovel plates 7, and the soil can be unloaded.

[0039] Example 6: The bottom of the shovel plate 7 is provided with an arc-shaped opening to reduce the contact area when it first comes into contact with the ground, making it easier for the shovel plate 7 to be scooped into the soil.

[0040] Example 7: Define the center of the virtual circle as the inner side. Do not polish the inner end face of all shovel plates 7, but polish the outer end face of all shovel plates 7. This reduces the friction between the outer end face of the shovel plates 7 and the soil, making it easier to lift the shovel plates 7 out of the soil. At the same time, the friction between the shovel plates 7 and the soil with seedlings is large, making it easier to shovel out the soil.

[0041] Any of the above optimized embodiments and necessary technical solutions can be combined into a complete embodiment, which can be compared with an embodiment in other applications in accordance with the principle of individual comparison.
