[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To achieve the above-mentioned utility model objectives, such as Figures 1-4As shown, this utility model provides a seedling spacing positioning transplanter for crop seedlings, including a handle 1. Limiting rods 2 are connected to the left and right sides of the lower end of the handle 1, and positioning bases 3 are connected to the rear ends of both limiting rods 2. A cutting pedal 4 is provided between the two limiting rods 2, and transplanting cylinders are connected to the rear sides of both ends of the cutting pedal 4. The transplanting cylinder includes a fixed half-cylinder 5 and a movable half-cylinder 19. Seedling entry openings are provided at the rear ends of both the positioning bases 3 and the fixed half-cylinder 5. A spacing adjustment component is provided between the handle 1 and the limiting rods 2, allowing adjustment of the spacing between the two limiting rods 2 and the spacing between the two transplanting cylinders. A clutch component is provided between the cutting pedal 4 and the transplanting cylinder, allowing the fixed half-cylinder 5 and the movable half-cylinder 19 of the transplanting cylinder to be joined together via the clutch component. The transplanter is used for cutting and clamping the soil around the roots of seedlings and for separating the seedlings from the soil. During the transplanting of crop seedlings, the transplanter includes a handle 1, a limiting rod 2, a positioning base 3, a cutting pedal 4, and transplanting cylinders on both sides. The transplanting cylinders on both sides are connected to the limiting rod 2 and the cutting pedal 4 through a clutch assembly, and are also connected to the handle 1 through the limiting rod 2 and the spacing adjustment assembly, so that the spacing between the two transplanting cylinders can be adjusted by the spacing adjustment assembly to meet the needs of seedlings with different spacing. The fixed half cylinder 5 and the movable half cylinder 19 of the transplanting cylinder can be joined together by the clutch assembly for cutting and clamping the soil around the roots of seedlings. At the same time, the fixed half cylinder 5 and the movable half cylinder 19 of the transplanting cylinder can be separated by the clutch assembly for separating the transplanting cylinder from the seedlings and the soil around the roots.

[0026] Specifically, transplanting seedlings involves two steps: digging holes and removing seedlings. During digging and removal, two positioning bases 3 are used to locate the digging position or the seedling roots. The two positioning bases 3 are placed on the outside of the digging position or the seedling roots. Holding the handle 1, the two transplanting cylinders are positioned perpendicular to the ground. Then, the transplanter is pressed down by stepping on the cutting pedal 4, inserting the two transplanting cylinders into the ground. This cuts and enlarges the soil at the digging position or the seedling roots, and the planter is rocked back and forth to allow for proper separation. The cut soil is separated from the underground soil. After shaking, the foot is used to hook the cutting pedal 4 upwards, and the transplanting cylinder is moved upwards to clamp and remove the cut soil, thereby removing the soil or seedling and seedling root soil from the digging position, completing the digging and seedling removal. Finally, the removed seedling and seedling root soil are placed into the digging position to complete the transplanting. The seedling can enter the transplanting cylinder or detach from the transplanting cylinder through the seedling inlet at the rear end of the positioning base 3 and the fixed half cylinder 5.

[0027] Preferably, the spacing adjustment assembly includes telescopic rods 6. Telescopic rods 6 are connected to the left and right sides of the lower end of the handle 1. Telescopic sleeves 7 connected to the inner end of the limiting rod 2 are sleeved on the outer ends of the two telescopic rods 6. The inner side of the upper end of the telescopic sleeve 7 is threaded with a fixing bolt 8 that fits against the upper end of the telescopic rod 6. During the process of adjusting the spacing between the two transplanting cylinders, the distance between the handle 1 and the limiting rod 2 is adjusted by sliding the telescopic sleeve 7 outside the telescopic rod 6, thereby adjusting the spacing between the two transplanting cylinders. The adjusted spacing is fixed by the fixing bolt 8.

[0028] Preferably, the clutch assembly includes an adjusting connecting plate 9. The adjusting connecting plate 9 is inserted into the left and right ends of the cutting pedal 4 and sleeved on the outside of the limiting rod 2. The two adjusting connecting plates 9 are connected to the two fixed half cylinders 5 by a connecting frame 10. The connecting frame 10 is sleeved on the outside of the connecting frame 10 and connected to the upper end of the movable half cylinder 19. The rear end of the separating sliding seat 11 is connected to a separating push-pull rod 12 that passes through the rear end of the limiting rod 2. While the spacing between the two transplanting cylinders is adjusted, the two adjusting connecting plates 9 can slide inside the two ends of the cutting pedal 4 and adjust their positions accordingly with the two limiting rods 2, while maintaining the connection with the cutting pedal 4. The transplanting cylinder can be connected to the adjusting connecting plate 9 through the connecting frame 10 and movably connected to the rear side of the limiting rod 2 through the adjusting connecting plate 9 so as to move up and down.

[0029] Preferably, the split-pull rod 12 is externally sleeved with a limiting seat 13 connected to the upper rear side of the adjusting connecting plate 9. A connecting groove 14 is provided on the lower rear side of the limiting rod 2, and the front end of the connecting groove 14 is connected to the split-pull groove 15 located inside the limiting rod 2. The split-pull groove 15 is inclined forward on both the upper and lower sides, and the split-pull roller 16 connected to the rear end of the limiting seat 13 is slidably connected inside the split-pull groove 15. An auxiliary pull rod 17 is connected to the center of the upper end of the cutting pedal 4 and passes through the lower end of the handle 1. An upper pull spring 18 located inside the handle 1 is sleeved on the outside of the auxiliary pull rod 17 and is elastically connected to the handle 1 through the upper pull spring 18. During the process of digging holes and taking seedlings, the cutting pedal 4 is stepped down. The cutting pedal 4 drives the connecting frame 10 to move downward through the adjusting connecting plate 9, and drives the fixed half cylinder 5 and the movable half cylinder 19 to move downward together through the connecting frame 10, and cuts and enlarges the soil.

[0030] Since the movable half-cylinder 19 is slidably connected to the lower end of the connecting frame 10 via the split-and-joint slide 11, and is slidably connected to the connecting groove 14 and the split-and-joint push-pull groove 15 via the split-and-joint push-pull rod 12 and the split-and-joint push-pull roller 16, and the split-and-joint push-pull rod 12 can be limited by the limiting seat 13 and the adjusting connecting plate 9, and the split-and-joint push-pull groove 15 is inclined forward on both the upper and lower sides, before stepping on the cutting pedal 4, the cutting pedal 4, the adjusting connecting plate 9, and the connecting frame 10 are at the uppermost position under the action of the auxiliary pull rod 17 and the upper pull spring 18, which drives the fixed half-cylinder 5 and the movable half-cylinder 19 to the uppermost position, so that the split-and-joint push-pull roller 16 is located inside the forward-inclined part on the upper side of the split-and-joint push-pull groove 15, allowing the split-and-joint push-pull roller 16 to drive the movable half-cylinder 19 to separate from the fixed half-cylinder 5 via the split-and-joint slide 11 and the split-and-joint push-pull rod 12.

[0031] Furthermore, when the cutting pedal 4 is stepped down, the splitting and pulling roller 16 will slide downward on the upper side inside the splitting and pulling groove 15 and slide backward inside the splitting and pulling groove 15, allowing the movable half-cylinder 19 to move backward and combine with the fixed half-cylinder 5 to form a complete cylindrical shape. The transplanting tube is inserted into the ground through the complete cylindrical shape to cut the soil or seedlings and the soil at the digging position.

[0032] Furthermore, as the cutting pedal 4 continues to be pressed to the lowest position, the splitting and pulling roller 16 will slide downward inside the splitting and pulling groove 15 and slide forward inside the splitting and pulling groove 15, allowing the movable half-cylinder 19 to move forward and separate from the fixed half-cylinder 5, and push the front side of the cut soil to form a cavity, thereby expanding the hole at the cutting position.

[0033] Furthermore, by shaking the soil inside the transplanting tube and the underground soil, the soil is broken apart from the underground soil, thereby separating the soil at the digging location or the soil around the seedling and its roots from the ground.

[0034] Furthermore, the transplanting cylinder is pulled out by inserting the upper hook into the cutting pedal 4 and with the assistance of the auxiliary pull rod 17 and the upper pull spring 18. In the initial upward movement of the transplanting cylinder, the split-pull roller 16 is located below the split-pull groove 15. The movable half-cylinder 19 moves closer to the fixed half-cylinder 5 and joins with it under the action of the split-pull groove 15 and the split-pull roller 16, and clamps and pulls out the soil. In the final stage where the soil is pulled out, the split-pull roller 16 is located above the split-pull groove 15. The movable half-cylinder 19 separates from the fixed half-cylinder 5 again under the action of the split-pull groove 15 and the split-pull roller 16, so that the soil at the digging position or the soil of the seedling and the seedling roots can be smoothly separated from the transplanting cylinder, and the dug soil and the soil of the seedling and the seedling roots can be easily removed, thus completing the digging and seedling removal.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
