[0033] The following combination Figures 1-10 , through specific embodiments and application scenarios, a seedling transplanting device provided by an embodiment of the present invention is described in detail.

[0034] like Figure 1 and Figure 2 As shown, the utility model provides a seedling transplanting device 100, comprising: a fixed rod 1, a triangular shovel 2 and a booster shovel 3. The bottom end of the fixed rod 1 is pointed. The triangular shovel 2 is used to deliver plant seedlings 200. The opposite sides of the triangular shovel 2 are respectively provided with bending portions 21. The two bending portions 21 are respectively rotatably mounted on the opposite side surfaces of the fixed rod 1 and close to the bottom end of the fixed rod 1. The triangular shovel 2 and the fixed rod 1 are arranged to form an openable and closable soil-breaking cone. The booster shovel 3 is fixed to the side of the triangular shovel 2 away from the fixed rod 1. The booster shovel 3 is used to be inserted into the soil following the soil-breaking cone and drive the triangular shovel 2 to rotate counterclockwise under the thrust of the soil, so that the soil-breaking cone opens.

[0035] The angle between the center line of the booster shovel 3 and the axis of the fixing rod 1 is an acute angle.

[0036] Specifically, the fixing rod 1 has a fixing section and a pyramid section connected to the fixing section, and the pyramid section is located at the bottom end of the fixing rod 1. The bottom surface of the pyramid section is connected to the fixing section. Among them, one of the cone surfaces of the pyramid section is flush with the first side surface of the fixing section. Figure 3 and Figure 4 As shown, the opposite sides of the triangular shovel 2 are bent toward the first side surface of the fixed rod 1, forming two bent portions 21. The two bent portions 21 and the middle portion of the triangular shovel 2 form a wedge-shaped groove for guiding the plant seedling 200 into the groove. The bottom end of the triangular shovel 2 is pointed, and the tip of the triangular shovel 2 corresponds to the tip of the fixed rod 1. The two bent portions 21 are rotatably mounted on opposite sides of the fixed rod 1, forming an openable and closable soil-breaking cone between the fixed rod 1 and the triangular shovel 2. As the triangular shovel 2 rotates relative to the fixed rod 1, the soil-breaking cone switches between an open and closed state.

[0037] like Figure 1 、 Figure 3 and Figure 4As shown, the booster shovel 3 is plate-shaped. Of course, the booster shovel 3 can also be triangular. The booster shovel 3 is fixed to the side of the triangular shovel 2 away from the fixed rod 1 and close to the tip of the triangular shovel 2. Figure 2 As shown, when planting seedlings, the operator first places the seedling 200 root-side down into the soil-breaking cone formed by the fixing rod 1 and the triangular shovel 2. The operator then holds the fixing rod 1 and inserts the cone vertically into the soil. Because the cone is lower than the level of the boosting shovel 3, it penetrates the soil before the boosting shovel 3. As the operator continues to apply force to the fixing rod 1, the cone's insertion depth gradually increases. Because the angle between the centerline of the boosting shovel 3 and the axis of the fixing rod 1 is acute, the boosting shovel 3 is tilted relative to the ground, allowing the boosting shovel 3 to gradually penetrate the soil along with the triangular shovel 2. As the boosting shovel 3 penetrates the soil, the soil's reaction force pushes the shovel 3 upward, driving the triangular shovel 2 counterclockwise. At this point, the soil-breaking cone opens, and the root of the seedling 200 is immersed in the soil. Next, the operator applies a vertical upward force to the fixing rod 1 to pull out the soil-breaking cone; in the process of pulling out the soil-breaking cone, the soil around the plant seedling 200 is gathered into the roots of the plant seedling 200, thereby covering the roots of the plant seedling 200, thereby completing a single seedling planting operation.

[0038] When it is necessary to plant seedlings again, the triangular shovel 2 can be manually rotated to move clockwise to close the soil-breaking cone, and then new plant seedlings 200 can be put into the triangular shovel 2 for planting.

[0039] The utility model provides a seedling planting device 100, the bottom end of the fixing rod 1 is pointed, and the opposite sides of the triangular shovel 2 are respectively provided with a bent portion 21, and the two bent portions 21 are respectively rotatably installed on the opposite sides of the fixing rod 1 and close to the bottom end of the fixing rod 1, so that the triangular shovel 2 and the fixing rod 1 are surrounded by an openable soil-breaking cone, and the triangular shovel 2 is used to place the plant seedlings 200. Since the angle between the center line of the boosting shovel 3 and the axis of the fixing rod 1 is acute, when the operator inserts the cone part of the soil-breaking cone into the soil, the boosting shovel 3 is inserted into the soil accordingly. In the process of the boosting shovel 3 inserting the soil, the reaction force of the soil pushes the boosting shovel 3 to move upward, and the boosting shovel 3 drives the triangular shovel 2 to rotate counterclockwise, the soil-breaking cone opens, and the plant seedlings 200 are inserted into the soil. When the soil-breaking cone is pulled out, the surrounding soil is gathered into the plant seedlings to cover the roots of the plant seedlings 200. The operation is simple and convenient, which greatly reduces the physical consumption of the operator and greatly improves the seedling planting efficiency.

[0040] In some embodiments, as Figure 1 、 Figure 2 and Figure 5As shown, the seedling transplanting device 100 also includes an elastic member 4. A first connecting shaft 11 is protruding from the side of the fixing rod 1. The first connecting shaft 11 is located above the triangular shovel 2. A first mounting shaft 22 is protruding from the top of the bent portion 21. One end of the elastic member 4 is rotatably sleeved on the first connecting shaft 11, and the other end is rotatably sleeved on the first mounting shaft 22. The triangular shovel 2 is designed to rotate clockwise under the elastic action of the elastic member 4, closing the soil-breaking cone.

[0041] Specifically, if Figure 5 As shown, the elastic member 4 has through holes 41 at opposite ends. The first connecting shaft 11 is rotatably inserted into one of the through holes 41, and the first mounting shaft 22 is rotatably inserted into the other through hole 41. The first connecting shaft 11 is located above the triangular shovel 2. When the soil-breaking cone is in a closed state, the elastic member 4 is in a natural state. When the soil-breaking cone is in an open state, the elastic member 4 contracts and stores force. After the booster shovel 3 is lifted out of the soil, the triangular shovel 2 automatically rotates clockwise under the elastic action of the elastic member 4, thereby closing the soil-breaking cone, making it convenient for the operator to perform the next seedling planting operation, and improving the operator's operational convenience. Optionally, the elastic member 4 is a spring.

[0042] In some embodiments, the elastic member 4, the first connecting shaft 11 and the first mounting shaft 22 are arranged in a set, and the two sets of elastic members 4 and the first connecting shaft 11 are respectively arranged on opposite sides of the fixed rod 1, so as to further increase the elastic force on the triangular shovel 2 through the two elastic members 4, ensuring that the earth-breaking cone 2 can be closed smoothly.

[0043] In some embodiments, the seedling transplanting device 100 further includes two first connecting rods 5. Figure 5 As shown, mounting holes 51 are provided at both ends of the first connecting rod 5. Figure 7 、 Figure 8 and Figure 9 As shown, second connecting shafts 12 are protruding from opposite sides of the fixed rod 1. The second connecting shaft 12 is located below the first connecting shaft 11. One end of the two first connecting rods 5 is rotatably sleeved on the two first mounting shafts 22. The other end of the two first connecting rods 5 is rotatably sleeved on the two second connecting shafts 12.

[0044] The two first connecting rods 5 can be symmetrically arranged on opposite sides of the fixed rod 1 along the axis of the fixed rod 1. Specifically, taking the installation arrangement of one set of first connecting rods 5, second connecting shaft 12, and first mounting shaft 22 as an example, the second connecting shaft 12 is rotatably inserted into one mounting hole 51 of the first connecting rod 5, and the first mounting shaft 22 is rotatably inserted into the other mounting hole 51. As a result, under the propulsion of the booster plate, the triangular shovel 2 first deflects slightly relative to the two first connecting rods 5. Then, the triangular shovel 2 drives the two first connecting rods 5 to rotate counterclockwise around the two second connecting shafts 12, until the top of the triangular shovel 2 contacts the first side surface of the fixed rod 1, and the triangular shovel 2 stops rotating.

[0045] By arranging two corresponding first connecting rods 5 between the triangular shovel 2 and the fixed rod 1 , the stability of the connection between the fixed rod 1 and the triangular shovel 2 and the flexibility of the triangular shovel 2 rotating relative to the fixed rod 1 are ensured by the two first connecting rods 5 .

[0046] In some embodiments, as Figure 7 、 Figure 8 and Figure 9 As shown, the opposite sides of the fixing rod 1 are respectively provided with stop blocks 16. The stop blocks 16 are located above the second connecting shaft 12. When the triangular shovel 2 rotates counterclockwise until it contacts the stop blocks 16, the triangular shovel 2 stops rotating.

[0047] In some embodiments, as Figure 1 As shown, the seedling transplanting device 100 also includes two second connecting rods 6. Third connecting shafts 13 are provided on opposite sides of the fixed rod 1. The third connecting shaft 13 is located below the second connecting shaft 12. A second mounting shaft 23 is protruded from each of the two bent portions 21, and the second mounting shaft 23 is located below the first mounting shaft 22. The second connecting rod 6 is located below the first connecting rod 5. One end of each second connecting rod 6 is rotatably mounted on the two second mounting shafts 23, and the other end of each second connecting rod 6 is rotatably mounted on the two third connecting shafts 13.

[0048] Optionally, the specific structure of the second connecting rod 6 can be the same as that of the first connecting rod 5. The installation method of the second connecting rod 6, the third connecting shaft 13, and the second mounting shaft 23 can also be the same as the installation method between the first connecting rod 5, the second connecting shaft 12, and the first mounting shaft 22 described above, and will not be repeated here. By providing two second connecting rods 6 below the two first connecting rods 5, the stability of the connection between the triangular shovel 2 and the fixed rod 1 is further enhanced, and the rotational flexibility of the triangular shovel 2 is further ensured.

[0049] In some embodiments, as Figure 10As shown, the seedling transplanting device 100 also includes an extension rod 7. The top of the fixed rod 1 has a connecting hole 14, and the hole wall of the connecting hole 14 is provided with an internal thread 141. At least part of the outer wall surface of the extension rod 7 is provided with an external thread adapted to the internal thread 141, and the extension rod 7 is threadedly connected to the fixed rod 1.

[0050] It is understandable that the fixed rod 1 can be used as a handle. Specifically, the extension rod 7 and the fixed rod 1 are located on the same vertical line. The connecting hole 14 is provided at one end of the fixed rod 1 away from its tip. The operator can adaptively choose to install the extension rod 7 according to actual use needs. In order to avoid the operator from bending over to work, the end of the extension rod 7 with an external thread can be screwed into the connecting hole 14, and the extension rod 7 and the fixed rod 1 can be fixedly connected together through the threaded connection between the external thread and the internal thread 141 of the hole wall of the connecting hole 14. When in use, the user holds the extension rod 7, inserts the soil-breaking cone vertically into the soil, and then pulls out the soil-breaking cone vertically upwards to complete a single seedling planting operation, which is very convenient.

[0051] Of course, when in use, the extension rod 7 can also be removed from the fixed rod 1, and the fixed rod 1 can be directly used as a handle to perform the seedling planting operation.

[0052] Furthermore, in some embodiments, Figure 7 、 Figure 8 and Figure 9 As shown, the seedling transplanting device 100 further includes at least one locking bolt 8. A side surface of the fixing rod 1 is provided with at least one threaded hole 15 that communicates with the connecting hole 14. The screw of the locking bolt 8 is passed through the threaded hole 15. As the screw is screwed in, the screw and the extension rod 7 abut against each other, thereby locking the extension rod 7 in the connecting hole 14.

[0053] Optional, such as Figure 7 、 Figure 8 and Figure 9 As shown, there are two threaded holes 15, and correspondingly, there are also two locking bolts 8. Of course, the number of threaded holes 15 and locking bolts 8 can also be one, three, or five. During assembly, the extension rod 7 is first screwed into the connecting hole 14 along the internal thread 141 of the connecting hole 14. The screw of the locking bolt 8 is then inserted into the threaded hole 15 until the end of the screw and the extension rod 7 are tightly seated. This further strengthens the connection between the extension rod 7 and the fixing rod 1 through the locking bolt 8, preventing the extension rod 7 from being detached from the fixing rod 1 during the seedling planting process, which could affect the safety and efficiency of the operator.

[0054] In some embodiments, the seedling transplanting device 100 further includes a first handle and a second handle. The first handle and the second handle are both located at the top of the fixed rod 1 and symmetrically fixed to opposite sides of the fixed rod 1 along the axis of the fixed rod 1. The first handle and the second handle are used to provide a balance point for the operator to transplant the seedlings.

[0055] Furthermore, in some embodiments, Figure 5 and Figure 6 As shown, the seedling transplanting device 100 also includes a cutting plate 9. The cutting plate 9 is vertically arranged on the boosting shovel 3. One side of the cutting plate 9 is fixedly connected to the triangular shovel 2. The cutting plate 9 is used to cut soil when the boosting shovel 3 drives the triangular shovel 2 to rotate counterclockwise.

[0056] Optionally, the cutting plate 9 is a triangular plate, wherein one of the right-angled sides of the triangular plate is fixed to the side of the triangular shovel 2 away from the fixed rod 1, and the other right-angled side is fixed to the side of the cutting plate 9 away from the tip of the triangular shovel 2, so that when the booster plate is pushed by the soil, the soil is cut by the oblique side of the triangular plate, so as to reduce the soil resistance encountered by the booster plate during the upward movement, thereby ensuring the flexibility of the booster plate to drive the triangular shovel 2 to rotate counterclockwise.

[0057] Optionally, the angle between the center line of the booster shovel 3 and the axis of the fixed rod 1 is 40°~60°, so as to ensure that the booster shovel 3 has a certain insertion depth when inserted into the soil, and to ensure that the booster shovel 3 has a large shoveling ability, so that the booster shovel 3 can drive the triangular shovel 2 to rotate counterclockwise under the reaction force of the soil, thereby enabling the soil-breaking cone to open to insert the roots of the plant seedlings 200 into the soil.

[0058] Optional, such as Figure 1 、 Figure 5 and Figure 6 As shown, the top of the triangular shovel 2 is gradually expanded to guide the seedling 200 into the shovel 2. The larger top of the triangular shovel 2 facilitates the leaves of the seedling 200 to be tucked into the larger diameter end of the shovel 2, thereby sliding along the inner wall of the shovel 2 into the bottom end of the shovel 2. Furthermore, the operator can quickly place the seedling 200 into the shovel 2 without bending over, making the seedling transplanting device 100 more convenient to use.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
