Technical Field

[0001] The utility model relates to the technical field of well cellar sealing, and more specifically, to a film sealing device for transplanting tobacco seedlings. Background Art

[0002] The well cellar type small-seedling transplanting technology for flue-cured tobacco has become the main technology in the tobacco planting industry in Guizhou and some other provinces. The existing well cellar type transplanting process includes the following processes: ridging, film laying, opening well cellar holes, transplanting seedlings, covering soil, watering root-fixing water and fertilizer, filling soil to seal the mouth, etc. Among them, filling soil to seal the mouth is to fill the well cellar mouth with fine soil when the tobacco seedlings grow out of the well cellar mouth and the growth point exceeds the well cellar mouth by 2 - 3 centimeters.

[0003] The application number is: CN202321207600.6, which discloses a film sealing device for transplanting tobacco seedlings, including: an operating rod, which is in the shape of a long rod; a sealing socket, the bottom of the operating rod is connected to the top of the sealing socket, the bottom of the sealing socket is open, and the diameter of the opening is larger than the well cellar hole; a soil separating cylinder, the soil separating cylinder is fixedly arranged outside the sealing socket, and there is an annular cavity between the soil separating cylinder and the sealing socket, and both the top and the bottom of the soil separating cylinder are open. Compared with the prior art, since the soil separating cylinder is arranged outside the sealing socket in this film sealer, the soil in the annular cavity can be made more uniform before the sealing socket is taken out upwards, so that a more uniform sealing socket can be realized.

[0004] In the use of the above solution, at least the following problems have not been solved. For example, since the soil separating cylinder 3 in the current solution lacks the design of a soil pressing structure, when the soil enters the soil separating cylinder 3, it is easy to be fluffy, and when the soil separating cylinder is taken out, the fluffy soil is very likely to collapse.

[0005] Therefore, in view of the above technical defect problems, it is necessary to propose a film sealing device for transplanting tobacco seedlings. Summary of the Utility Model

[0006] The purpose of the utility model is to propose a film sealing device for transplanting tobacco seedlings aiming at the above defects. When the device is in use, it has the characteristic of compacting the soil downward, so that the soil entering the soil separating cylinder can be tightly compacted, thus effectively avoiding the situation of soil collapse when the film sealer is taken out.

[0007] The utility model provides a film sealing device for transplanting tobacco seedlings, including:

[0008] An operating rod, the bottom of the operating rod is provided with a sealing socket, and an opening for covering the tobacco seedlings is opened at the center of the bottom of the sealing socket;

[0009] Soil separation cylinder, the soil separation cylinder is arranged on the outer periphery of the nest covering, and a containing space for loading soil is formed between the inner end face of the soil separation cylinder and the outer end face of the nest covering. At least two support rods are welded between the top end of the inner wall of the soil separation cylinder and the outer side face of the nest covering;

[0010] Soil pressing cover, the soil pressing cover is slidably arranged at the upper end of the outer wall of the operating rod, and the lower end of the soil pressing cover is arranged opposite to the containing space in the soil separation cylinder. A through groove corresponding to the support rod is opened at the bottom end face of the soil pressing cover. Among them, the through groove is communicated with the outer end face and the inner end face of the soil pressing cover.

[0011] Preferably: The soil pressing cover is integrally in the shape of a bottle cap structure, wherein the upper part of the soil pressing cover is a complete closed plane, and the lower part forms an annular groove.

[0012] Preferably: A connecting block is fixedly arranged at the lower end of the outer wall of the operating rod. A spring is arranged through the outer wall of the operating rod on the upper surface of the connecting block, and the upper end of the spring is connected to the inner top end face of the soil pressing cover.

[0013] Preferably: A rectangular limiting groove is opened in the outer wall of the operating rod in the vertical direction. A limiting block is slidably arranged in the limiting groove, and one end of the limiting block is connected to the soil pressing cover.

Specific embodiments

[0024] Next, in combination with the embodiments, the technical solutions of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

[0025] As shown in the attached Figure 1 to the attached Figure 4 figures: A film-sealing device for transplanting tobacco seedlings includes an operating rod 1, a soil-sealing cover 2, a soil-separating cylinder 3, and a soil-pressing cover 4. The soil-sealing cover 2 is fixedly arranged at the bottom of the operating rod 1, and an opening 21 for covering the tobacco seedlings is provided at the center of the bottom of the soil-sealing cover 2. The soil-separating cylinder 3 is arranged on the outer periphery of the soil-sealing cover 2, and an accommodating space 31 for loading soil is formed between the inner end surface of the soil-separating cylinder 3 and the outer end surface of the soil-sealing cover 2. At the same time, at least two support rods 32 are welded between the top end of the inner wall of the soil-separating cylinder 3 and the outer side surface of the soil-sealing cover 2. The support rods 32 mainly provide a connection support point between the soil-separating cylinder 3 and the soil-sealing cover 2. Finally, the soil-pressing cover 4 is slidably arranged at the upper end of the outer wall of the operating rod 1, and the lower end of the soil-pressing cover 4 is also arranged opposite to the accommodating space 31 inside the soil-separating cylinder 3.

[0026] In the above solution, through the arrangement of the soil-sealing cover 2 and the opening 21, it is convenient to cover the tobacco seedlings at the well cellars through the opening 21. The corresponding setting relationship between the soil-pressing cover 4 and the accommodating space 31 allows the lower end of the soil-pressing cover 4 to be pushed into the accommodating space 31 when the soil-pressing cover 4 moves downward, so as to realize the compaction of the soil in the accommodating space 31.

[0027] Furthermore, the diameter of the opening 21 should be slightly larger than the well cellar hole, and the internal space of the opening 21 needs to be larger than the volume of the tobacco seedlings. Through this design, when sealing the film, the sealing socket 2 can just cover the tobacco seedlings.

[0028] Furthermore, the soil separation cylinder 3 has an inner diameter that is wider at the top and narrower at the bottom from top to bottom. With this design, a funnel structure can be formed at the upper part of the soil separation cylinder 3, and a cylindrical structure can be formed at the lower part. In this way, when the user needs to shovel soil into the accommodation space 31, the funnel structure at the upper part of the soil separation cylinder 3 can be utilized, and thus the entire soil shoveling process can become more convenient.

[0029] Furthermore, the soil pressing cover 4 is integrally in the shape of a bottle cap. Specifically, the upper part of the soil pressing cover 4 is a complete closed plane, and the lower part forms an annular groove structure. With this design, when the soil pressing cover 4 moves downward, the groove part at the lower end of the soil pressing cover 4 can be correspondingly inserted into the accommodation space 31. After insertion, the soil in the accommodation space 31 can be compacted.

[0030] Furthermore, the bottom height of the soil separation cylinder 3 should be higher than the bottom height of the sealing socket 2. Through this design, a certain drop can be formed between the soil separation part and the lower end of the sealing socket 2. Due to the drop, part of the soil falling into the accommodation space 31 can pour out outward at the bottom of the soil separation cylinder 3. This helps to effectively reduce the situation where the soil collapses and falls into the well cellar hole when the sealing socket 2 is taken out.

[0031] As Figures 1 to 3 shown, in this embodiment, a connecting block 5 is fixedly arranged along the lower end of the outer wall of the operating rod 1. The upper surface of the connecting block 5 is provided with a spring 51 passing through the outer wall of the operating rod 1, and the upper end of the spring 51 is also connected to the inner top surface of the soil pressing cover 4. With this design, the spring 51 can apply an upward elastic force to the soil pressing cover 4. When the soil pressing cover 4 finishes compacting the soil downward, the spring 51 can quickly push the soil pressing cover 4 upward under the action of the elastic force. After moving, the soil pressing cover 4 can quickly move away from the soil separation cylinder 3. In this way, the accommodation space 31 can be reopened again, thus facilitating shoveling soil into the accommodation space 31 for the second time and using it.

[0032] Furthermore, a through groove 41 corresponding to the support rod 32 is opened at the bottom end face of the soil pressing cover 4, and the through groove 41 is also in communication with the outer end face and the inner end face of the soil pressing cover 4. With this design, when the soil pressing cover 4 continues to move downward, the support rod 32 can normally pass through the through groove 41. After passing through, it can be avoided that the support rod 32 interferes with the movement of the soil pressing cover 4. In this way, it can be ensured that the soil pressing cover 4 can normally compact the soil in the accommodation space 31, and after compaction, combined with the elastic force of the spring 51, the moving soil pressing cover 4 can quickly reset.

[0033] Furthermore, a rectangular-shaped limiting groove 6 is formed in the outer wall of the operating rod 1 in the vertical direction. A limiting block 61 is slidably arranged in the limiting groove 6, and one end of the limiting block 61 is connected to the soil pressing cover 4. This design enables the soil pressing cover 4 to be limited by the limiting groove 6 and the limiting block 61 when sliding downward. After being limited, it can be ensured that the soil pressing cover 4 will not deflect when moving downward, so that the through groove 41 of the soil pressing cover 4 can stably dock with the support rod 32, and then the soil pressing cover 4 can stably contact the soil in the accommodating space 31.

[0034] Furthermore, a ring-shaped pressing plate 33 is fixedly arranged at the lower end of the outer wall of the soil separating cylinder 3. The bottom surface of the pressing plate 33 is flush with the bottom end surface of the soil separating cylinder 3. This design can provide a reverse resistance by the pressing plate 33 in contact with the ground when the user drives the soil pressing cover 4 to move downward, so as to effectively avoid the problem that the soil separating cylinder 3 is inserted too deeply into the soil due to the excessive downward movement force of the soil pressing cover 4.

[0035] Finally, it should be noted that the above embodiments are only specific implementation manners of the present application, which are used to illustrate the technical solutions of the present application, rather than limiting them. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that any person skilled in the art within the technical scope disclosed in the present application can still modify the technical solutions recorded in the foregoing embodiments, or can easily think of changes, or make equivalent replacements for some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
