Description

Technical Field

[0001] This utility model relates to the field of tobacco seedling transplanting technology, and in particular to a transplanting distancer. Background Technology

[0002] Transplanting cigar seedlings is a crucial step in cigar cultivation. Its main purpose is to move young cigar seedlings from nurseries (such as greenhouses or seedling trays) to the field, allowing them more space and a more suitable environment to continue growing and eventually develop into mature cigar plants. Current methods involve placing the seedlings at specific intervals and layouts at the intended transplanting location to ensure a reasonable distribution. Normally, this is done manually based on experience or using measuring tools; seedlings that are too large or too small will negatively impact their growth.

[0003] Existing technology, such as the Chinese utility model patent with publication number CN 217742252 U and publication date of November 8, 2022, discloses a tobacco seedling transplanting row spacing fixing device, which solves the problem that the distance of existing tobacco seedling transplanting devices cannot be adjusted according to the actual planting situation, and relates to the field of tobacco seedling transplanting technology. It includes a frame and symmetrically arranged wheels on both sides of the frame. Several seedling fixing components are detachably connected to the outer ring of each wheel, and a rotating shaft is rotatably connected to the center of each wheel. A connecting rod is provided on the frame, and the rotating shaft is connected to the connecting rod through a spacing adjustment component. This utility model adjusts the distance between the two wheels through the spacing adjustment component, and is applicable to punching and spacing tobacco seedlings with various row spacings. Although this patent allows for detachable connection between the seedling fixing component and the wheels, facilitating the adjustment of the seedling spacing, the diameter of the wheels cannot be changed, which has certain limitations. Utility Model Content

[0004] To address the shortcomings in the aforementioned background technology, this utility model proposes a cigar seedling transplanter for determining the row and plant spacing, which solves the problem that existing cigar seedling transplanting devices cannot be adjusted according to actual conditions.

[0005] The technical solution of this utility model is implemented as follows: a cigar seedling transplanting plant spacing spacer includes a positioning plate and an adjustable ring structure. The adjustable ring structure is movably connected to the positioning plate. At least two spacers are movably connected circumferentially to the adjustable ring structure. A handrail is rotatably connected to the middle of the positioning plate.

[0006] More preferably, the spacer includes a positioning block with a screw connected to it. The screw passes through the adjustable ring structure and is connected to a positioning nut located inside the adjustable ring structure.

[0007] More preferably, the positioning block is a positioning cone, and the screw is connected to the bottom of the positioning cone.

[0008] More preferably, the adjustable ring structure includes an arc-shaped component one and an arc-shaped component two, one end of which is detachably connected to both sides of the positioning plate, the free end of the arc-shaped component one is stacked and connected to the side where the arc-shaped plate two is connected to the positioning plate, and the free end of the arc-shaped component two is connected to the side where the arc-shaped plate one is connected to the positioning plate.

[0009] More preferably, both the first arc-shaped component and the second arc-shaped component include an arc-shaped plate, which has a plurality of evenly arranged adjustment holes. One end of the arc-shaped plate is fixedly connected to a connecting plate, and the other end of the arc-shaped plate is connected to a bolt pair.

[0010] More preferably, the arc-shaped plate is provided with a strip-shaped hole.

[0011] More preferably, both sides of the positioning plate are provided with a second strip-shaped hole, and the second strip-shaped hole is provided with a bolt pair that passes through the first strip-shaped hole and fixes the connecting plate to the positioning plate.

[0012] More preferably, a bearing is connected to the center of the positioning plate, and a rotating shaft that cooperates with the handrail is connected inside the bearing.

[0013] More preferably, the handrail includes a telescopic rod assembly, one end of which is fixedly connected to a pivot, and the other end of which is connected to a handle, with an arc-shaped transition between the telescopic rod assembly and the handle.

[0014] More preferably, the telescopic rod assembly includes a sleeve, a sliding rod is movably connected inside the sleeve, and a set screw for fixing the position of the sliding rod is threaded onto the sleeve.

[0015] The beneficial effects of this utility model are as follows: The positioning plate of this utility model is connected to an adjustable ring structure. Both the adjustable ring structure and the positioning plate rotate around the connection point between the handle and the positioning plate, forming a walking wheel that can move in the field. A spacer is set on the outer circumference of the adjustable ring mechanism to position the spacing between cigar seedlings. The positioning is accurate and fast, solving the problem of inaccurate positioning of cigar seedling spacing by manual methods. The size of the adjustable ring structure can be adjusted according to actual usage needs. Combined with the adjustment of the position of the spacer, the adjustment range is wide, solving the problem that the fixed diameter of the walking wheel cannot be arbitrarily adjusted in terms of the fixed distance position.

Detailed Implementation

[0020] 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.

[0021] like Figure 1 As shown in Example 1, a cigar seedling transplanting spacing device includes a positioning plate 1 and an adjustable ring structure. The adjustable ring structure is movably connected to the positioning plate 1. At least two spacing elements are circumferentially connected to the adjustable ring structure, and the positioning elements correspond to the adjustable ring structure. A handle 2 is rotatably connected to the center of the positioning plate 1. The positioning plate 1 is connected to the adjustable ring structure, and both the adjustable ring structure and the positioning plate 1 rotate around the rotatable connection between the handle 2 and the positioning plate 1, forming a walking wheel that can move in the field. The spacing elements are set on the outer circumference of the adjustable ring structure to position the spacing between the cigar seedlings accurately and quickly, solving the problem of inaccurate positioning of cigar seedling spacing by manual methods. The size of the adjustable ring structure can be adjusted according to actual usage needs, and with the adjustment of the position of the spacing elements, the adjustment range is wide, solving the problem that the spacing position cannot be arbitrarily adjusted due to the fixed diameter of the walking wheel.

[0022] In this embodiment, the positioning component includes a positioning block 3, on which a screw 4 is connected. The screw 4 passes through an adjustable ring structure and connects to a positioning nut 5 located inside the adjustable ring structure. The positioning block 3 is a positioning cone, and the screw 4 is connected to the bottom of the positioning cone. The screw 4 on the positioning cone passes through the adjustable ring structure and cooperates with the positioning nut 5 to fix the positioning cone on the adjustable ring structure. The positioning cone and the screw 4 are an integral structure, or they can be connected as a whole by a threaded connection. The positioning block 3, being a positioning cone, allows for a certain degree of drilling, resulting in a more obvious positioning effect.

[0023] like Figure 2 As shown in Example 2, a cigar seedling transplanting spacing device differs from the technical solution of Example 1 in that the adjustable annular structure includes an arc-shaped component 6 and an arc-shaped component 7. One end of the arc-shaped component 6 and the arc-shaped component 7 are detachably connected to both sides of the positioning plate 1. The free end of the arc-shaped component 6 is stacked and connected to the side where the arc-shaped component 7 is connected to the positioning plate 1, and the free end of the arc-shaped component 7 is connected to the side where the arc-shaped component 6 is connected to the positioning plate 1. That is, the arc-shaped component 6 and the arc-shaped component 7 are stacked end to end to form a ring-like structure. Both the arc-shaped component 6 and the arc-shaped component 7 include an arc-shaped plate 8, which has several evenly arranged adjustment holes 8-1. One end of the arc-shaped plate 8 is fixedly connected to a connecting plate 9, and the other end of the arc-shaped plate 8 is connected to a bolt pair 10. The connecting plate 9 is symmetrically connected to the positioning plate 1. The curvature of the arc plate 8 is adjusted according to the actual connection position, forming a near-circular structure that allows for walking in the field without affecting movement. Bolts of bolt pair 10 pass through the adjustment holes 8-1 of arc-shaped part 6 and arc-shaped part 7 and are connected to nuts, so that the connecting plate 9 of arc-shaped part 6 and the arc plate 8 of arc-shaped part 7 are connected as a whole. The shape of the near-circular structure can be adjusted by the bolts passing through different adjustment holes 8-1, thereby adjusting the size of the adjustable ring structure.

[0024] In this embodiment, the arc-shaped plate 8 is provided with a first slot 11. The positioning plate 1 has second slots 12 on both sides. A second bolt pair 13 passes through the first slot 11 and fixes the connecting plate 9 to the positioning plate 1 within the second slot 12. The bolts of the second bolt pair 13 pass through the first slot 11 and the second slot 12 and are connected to a nut, connecting the positioning plate 1 and the connecting plate 9. The slots allow for stepless adjustment, providing a wide adjustment range and facilitating the connection between the arc-shaped plates 8 to form a circular structure.

[0025] All other structures are the same as in Example 1.

[0026] like Figure 1 As shown in Example 3, a cigar seedling transplanting spacing device differs from the technical solution of Example 1 in that a bearing is connected to the middle of the positioning plate 1, and a rotating shaft 14 that cooperates with the handle 2 is connected inside the bearing. The handle 2 includes a telescopic rod assembly, one end of which is fixedly connected to the rotating shaft 14, and the other end of which is connected to a handle 18. An arc-shaped transition is provided between the telescopic rod assembly and the handle 18. The telescopic rod assembly includes a sleeve 15, and a sliding rod 16 is movably connected inside the sleeve 15. A set screw 17 for fixing the position of the sliding rod 16 is threaded onto the sleeve 15. The set screw 17 fixes the length of the telescopic rod assembly, realizing the adjustment of the length of the handle 2. Pushing the handle 2 allows the adjustable ring structure to rotate around the rotating shaft 14, realizing the positioning of the positioning cone in the field.

[0027] All other structures are the same as in Example 2.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
