Description

Technical Field

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

[0002] Currently, most tobacco-growing areas rely on manual transplanting of tobacco seedlings. The complete transplanting process involves a series of steps, including digging planting holes, applying base fertilizer, and filling the holes. During this process, human error can easily lead to problems such as missed plantings, seedling burn, and seedling damage, resulting in slow growth or even death of the seedlings and affecting the yield and quality of tobacco leaves. Furthermore, manual labor requires frequent and prolonged squatting, which is unsuitable for large-scale seedling transplanting. Although many seedling transplanting devices exist, none completely solves all the aforementioned problems.

[0003] For example, existing tobacco transplanting devices have a lifting structure that allows for opening and closing. However, during use, base fertilizer needs to be laid at the bottom of the planting hole first, and the depth must be strictly controlled. If the base fertilizer is touched, it can easily burn the seedlings. Another example is a tobacco well-cell transplanting comb-type well-cell fixing device. After the transplanting work is completed, there is no need to manually pull the fixing cylinder out of the tobacco well-cell. The automatic pop-out structure can effectively save manual labor, but it still cannot solve the problem of pre-filling base fertilizer. Utility Model Content

[0004] The purpose of this utility model is to provide a device that integrates hole-opening, base fertilizer laying, and hole-filling operations, without causing seedling burn or damage to tobacco seedlings, in order to address the shortcomings of the aforementioned background technology.

[0005] To achieve the above objectives, this utility model provides a tobacco seedling transplanting device for tobacco planting, comprising an inner cylinder and an outer cylinder. The inner cylinder and the outer cylinder are coaxially arranged. The inner cylinder is used to place the tobacco seedlings to be transplanted. The bottom of the outer cylinder is provided with a conical body, which is composed of multiple petals. Each petal of the conical body is connected to the inner cylinder through a linkage mechanism, so that when the inner cylinder moves axially relative to the outer cylinder, the opening and closing of the conical body can be controlled. The interior of the conical body is provided with a through hole and a stepped surface. The size of the through hole matches the outer diameter of the inner cylinder. The height of the stepped surface is greater than the bottom of the conical body. The partition formed by the stepped surface, the inner wall of the conical body, and the outer wall of the inner cylinder is used to hold base fertilizer.

[0006] Furthermore, the stepped surface is inclined, with the position near the central axis of the inner cylinder higher than the position far from the central axis of the inner cylinder.

[0007] Furthermore, the linkage mechanism includes a first link, a second link, a third link, and a connecting sleeve. The first link is correspondingly and fixedly connected to each lobe of the cone. The first end of the second link is fixedly connected to the first link, the second end of the second link is hinged to the third link, the third link is hinged to the connecting sleeve, the connecting sleeve is located outside the inner cylinder and fixedly connected to the inner cylinder, and the first end of the second link is hinged to the outer cylinder.

[0008] Furthermore, an operating rod is provided at the upper part of the inner cylinder, and the operating rod extends to the outside of the outer cylinder through a slot on the surface of the outer cylinder. An operating ring is provided at the upper part of the outer cylinder.

[0009] Furthermore, a positioning component is provided between the outer cylinder and the inner cylinder. The positioning component includes a positioning groove, a positioning block and a spring. The positioning groove is fixedly connected to the outer cylinder. The positioning block is movably disposed in the positioning groove and connected to the spring. The outer wall of the inner cylinder is provided with a plurality of positioning holes that match the positioning block.

[0010] The above-mentioned solution of this utility model has the following beneficial effects:

[0011] The tobacco seedling transplanting device provided by this utility model, through the combination of inner and outer cylinders, the setting of conical body and connecting rod mechanism, can directly complete the opening, laying of base fertilizer and filling of hole operations through this device. Moreover, the setting of conical body will not cause seedling burning or damage to tobacco seedlings. The overall structure is simple and easy to operate, effectively improving the field work efficiency of tobacco planting and reducing labor costs.

Detailed Implementation

[0018] To make the technical problems, solutions, and advantages of this utility model clearer, a detailed description will be provided below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1 As shown, an embodiment of this utility model provides a tobacco seedling transplanting device for tobacco cultivation, including an inner cylinder 1 and an outer cylinder 2. The inner cylinder 1 and outer cylinder 2 are coaxially arranged. The inner cylinder 1 is used to place the tobacco seedlings to be transplanted, and the space between the outer cylinder 2 and the inner cylinder 1 is used to add base fertilizer, which is then spread around the inside of the holes. A cone-shaped body 3 with a conical outer surface is provided at the bottom of the outer cylinder 2. The cone-shaped body 3 is composed of multiple segments and can be considered as an extension of the bottom of the outer cylinder 2. Each segment of the cone-shaped body 3 is connected to the inner cylinder 1 via a linkage mechanism, so that the cone-shaped body 3 can be controlled to open and close when the inner cylinder 1 moves axially relative to the outer cylinder 2.

[0022] At the same time, such as Figure 2As shown, in one specific embodiment of this example, the linkage mechanism includes a first link 4, a second link 5, a third link 6, and a connecting sleeve 7. The first link 4 is correspondingly and fixedly connected to each lobe of the cone 3. The first end of the second link 5 is fixedly connected to the first link 4 and rotates synchronously. The second end of the second link 5 is hinged to the third link 6, and the third link 6 is simultaneously hinged to the connecting sleeve 7. The connecting sleeve 7 is located outside the inner cylinder 1 and is fixedly connected to the inner cylinder 1. In addition, the first end of the second link 5 is hinged to the outer cylinder 2. Therefore, when the inner cylinder 1 moves downward relative to the outer cylinder 2, the first link 4 is rotated through the third link 6 and the second link 5, causing the cone 3 to open; conversely, the cone 3 closes.

[0023] At the same time, such as Figure 3 As shown, in this embodiment, the conical body 3 has a through hole 8 and a stepped surface 9 inside. The size of the through hole 8 matches the outer diameter of the inner cylinder 1, and when the conical body 3 is closed, the bottom of the inner cylinder 1 is located in the through hole 8. The height of the stepped surface 9 is greater than the bottom of the conical body 3, and the partition between the stepped surface 9, the inner wall of the conical body 3, and the outer wall of the inner cylinder 1 is used to accommodate base fertilizer. In a preferred embodiment, the stepped surface 9 is inclined, with the position near the central axis of the inner cylinder 1 higher than the position away from the central axis of the inner cylinder 1.

[0024] In this embodiment, an operating rod 10 is provided at the upper part of the inner cylinder 1. The operating rod 10 extends to the outside of the outer cylinder 2 through a slot on the surface of the outer cylinder 2 to facilitate hand-held operation by the operator. An operating ring 11 is provided at the upper part of the outer cylinder 2. During operation, the operating rod 10 is first pulled to the highest position, at which point the cone 3 is closed. The device is aligned with the location of the hole, and the entire device is pressed down through the operating ring 11 to open the hole. The operating rod 10 is then lifted and the soil at the bottom of the outer cylinder 2 is shaken off and cleared (if the soil is compacted and causes blockage, the soil can be finely cleared by opening the cone 3). Then, the base fertilizer is put in from the position between the outer cylinder 2 and the inner cylinder 1 at the top of the device. After the base fertilizer reaches the cone 3, it accumulates in the aforementioned partition. Slight shaking is used to distribute the base fertilizer evenly in the partition. The device is then placed into the hole, and the operating rod 10 is pressed down to open the cone 3, allowing the base fertilizer to be scattered onto the soil around the inside of the hole. Due to the inclined design of the stepped surface 9, the base fertilizer does not fall immediately when the cone 3 opens. It only falls when a certain angle is reached, ensuring that the fallen base fertilizer is a certain distance from the transplanting position of the tobacco seedlings and preventing them from being burned. After the cone 3 is fully opened, the tobacco seedlings are then placed into the inner cylinder 1. The entire device is then slowly lifted. Understandably, during the lifting process, the upper part of the tobacco seedlings remains in the inner cylinder 1, and the soil sprinkled around the holes does not compress the seedlings, thus achieving the purpose of protecting the seedlings.

[0025] In a preferred embodiment, a positioning assembly is further provided between the outer cylinder 2 and the inner cylinder 1. The positioning assembly includes a positioning groove 12, a positioning block 13, and a spring 14. The positioning groove 12 is fixedly connected to the outer cylinder 2, and the positioning block 13 is movably disposed within the positioning groove 12 and connected to the spring 14. The outer wall of the inner cylinder 1 is provided with multiple positioning holes 15 that match the positioning block 13. When the inner cylinder 1 moves to its highest position relative to the outer cylinder 2, the positioning hole 15 at the lowest point of the inner cylinder 1 aligns with the positioning block 13, allowing the positioning block 13 to be inserted into the positioning hole 15, thus maintaining the inner cylinder 1 at that height. Pressing the inner cylinder 1 overcomes the limitations of the positioning block 13 (with an inclined surface) and the spring 14, allowing the inner cylinder 1 to move relative to the outer cylinder 2. In other relative positions (e.g., when the inner cylinder 1 moves to its lowest point relative to the outer cylinder 2), it can also be held in place by the corresponding positioning holes 15, facilitating operation by the operator.

[0026] In summary, the tobacco seedling transplanting device provided in this embodiment has a simple overall structure and is easy to operate. It can be used to directly complete tasks such as opening holes, laying base fertilizer, and filling holes without causing seedling burn or damage. This effectively improves the efficiency of field work in tobacco planting and reduces labor costs.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
