Detailed implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Terms such as "upper", "lower", "left", "right", "middle", and "one" cited in the present invention are only for the convenience of clear narration and are not used to limit the scope of implementation of the present invention. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present invention.

[0023] Refer to Figures 1 - 5 , a seedling transplanting device for agricultural planting, including a placement box 1 and a main frame 3. The placement box 1 and the main frame 3 are fixedly connected by a first connecting rod 2. A cylinder 4 is fixedly installed on the inner wall surface of the upper part of the main frame 3. The telescopic end of the cylinder 4 is fixedly installed with a connecting plate 5. Two second connecting rods 6 are fixedly installed on the lower end surface of the connecting plate 5. The other end of each second connecting rod 6 is fixedly connected with a cross bar. Both ends of each cross bar are fixedly connected with a first sliding tube 7. A probe 8 is fixedly installed on the lower end surface of each first sliding tube 7.

[0024] A cross plate 14 is fixedly installed on one side of the first sliding tube 7 in the middle position. A spring 15 is fixedly installed on the lower end surface of the cross plate 14. The other end of the spring 15 is fixedly connected with a snap ring 16. The snap ring 16 is also rotatably connected to one side of the first sliding tube 7.

[0025] Through holes completely penetrating the main frame 3 are provided on both sides of the main frame 3. A lifting cross bar 10 is slidably connected inside the two through holes.

[0026] A plurality of third connecting rods 11 are fixedly installed on one side of the connecting plate 5. The other end of each third connecting rod 11 is fixedly installed with a square frame 12. A plurality of spikes 13 are fixedly installed on the lower end surface of the square frame 12. When the probe 8 penetrates into the soil, the square frame 12 will move synchronously with the probe 8, so that the soil can be softened in advance, making the soil in front loose, which is beneficial for the next transplanting.

[0027] The probe 8 is arranged in the shape of a quadrangular pyramid. The inside of each probe 8 is a hollow structure. Each probe 8 can be divided into two expanding parts that are axially symmetric and rotatably connected to each other. One of the expanding parts is fixedly connected to the lower end surface of the first sliding tube 7.

[0028] Two support rods are fixedly installed on both side surfaces of the placement box 1. A runner is arranged below each support rod. The support rods and the runners can make the operation height more appropriate and make the whole easy to move.

[0029] Three second sliding tubes 17 are fixedly installed on one side of the placement box 1. Each second sliding tube 17 corresponds to a first sliding tube 7. The lower end of each second sliding tube 17 is in contact with the corresponding first sliding tube 7. When placing the seedling plants, the seedling plants can be directly placed with their roots downward on the surface of each second sliding tube 17, and slide through the first sliding tube 7 along the inclined plane and finally fall into the probe 8, which is convenient for subsequent operations.

[0030] The lower end of the spike 13 is at the same height as the lower end of the probe 8. The material of the spike 13 is set as stainless steel material. Mud and water can easily cause metal to rust. If the metal rusts, it will affect the hardness and service life of the spike 13. Therefore, rust should be avoided as much as possible in the material selection.

[0031] In the present utility model, when in use, first put the seedlings to be transplanted into the placement box 1, place the seedlings in the placement box 1 with their roots downward on the surface of the second sliding tube 17, and fall into the corresponding probe 8 through the second sliding tube 17. Then, through the air cylinder 4, the air cylinder 4 pushes the connecting plate 5, the connecting plate 5 pushes the second connecting rod 6, and further pushes the probe 8 to make the probe 8 extend into the soil layer. During the extension process, the inclined plane of an expanding part of the probe 8 will contact the lifting cross bar 10. Under the extrusion of the lifting cross bar 10, this expanding part will gradually rotate and form an increasingly large opening with another expanding part, and finally implant the root of the seedling into the soil layer. At this time, the lifting cross bar 10 has passed over the inclined plane at the lower end of the snap ring 16 and is clamped inside the snap ring 16. At this time, the two expanding parts of the probe 8 remain separated from each other, so that the seedling plants will not be damaged by the probe 8. When the probe 8 leaves the soil layer, the loose soil that has been extruded will automatically bury the root of the seedling under the action of gravity. When the probe 8 reaches the highest position under the contraction action of the air cylinder 4, the upper end of the snap ring 16 contacts the fixed cross bar 9, the snap ring 16 rotates under the pressure, and the lifting cross bar 10 falls from inside the snap ring 16, then the two expanding parts of the probe 18 return to the closed state. After completing one planting, use the runners below the placement box 1 to push the whole to the next planting place. Repeat the above operations.

[0032] The probe 8 is extended into the soil layer through the air cylinder 4, and the seedling plants are implanted into the soil through the rotation and expansion of the two expanding parts of the probe 8, and at the same time, the seedling plants will not be damaged, saving manpower.

[0033] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "linkage", "fixation" and the like shall be understood in a broad sense.

[0034] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
