Description

Technical Field

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

[0002] Transplanting tobacco seedlings is a crucial step in tobacco cultivation. After transplanting, the seedlings' root systems are not yet fully adapted to the new environment, making them highly sensitive to environmental changes and often threatened by natural disasters such as drought, heavy rainfall, and hail. Simultaneously, natural light conditions often fail to meet the seedlings' specific spectral requirements, hindering effective growth. Existing protective measures, such as simple plastic film covering or simple scaffolding, cannot simultaneously achieve multiple functions like heat and moisture retention, protection, and light-promoting growth, resulting in low seedling survival rates, slow growth, and negatively impacting tobacco yield and quality.

[0003] Existing technology, such as the Chinese utility model patent CN217771017U (publication number CN217771017U, publication date 2022-11-11), discloses a tobacco seedling protection device for field ridging, including a protective cover for covering the tobacco seedlings and a support for fixing the protective cover. The support includes a fixed rod movable along the height direction of the protective cover and a control component for controlling the movement of the fixed rod. Although this patent can cover the tobacco seedlings with the protective cover, preventing damage to the tobacco seedlings caused by soil covering the leaves during field ridging and tillage operations, the structure of this patent is complex and cannot meet the specific spectral requirements of tobacco seedlings. Utility Model Content

[0004] In view of the shortcomings in the above-mentioned background technology, this utility model proposes a multi-functional protective device for tobacco seedling transplanting, which solves the problem in the prior art that tobacco seedlings exposed to the air after transplanting cannot guarantee the temperature and moisture of the environment after transplanting. It can create a suitable growth environment for tobacco seedlings and improve the survival rate and growth quality of tobacco seedlings after transplanting.

[0005] The technical solution of this utility model is as follows: a multifunctional protective device for transplanting tobacco seedlings includes an anti-tilting rod, and at least one cover for covering the transplanted tobacco seedlings is connected to the anti-tilting rod. The cover is a transparent or semi-transparent cup-shaped structure and a light filter layer is provided on the cover.

[0006] More preferably, the top of the cover is a hemispherical shell, the lower part of the cover is provided with an annular baffle, and the lower part of the annular baffle is provided with a plate for fixing the cover to the ground.

[0007] More preferably, the side wall of the cover is provided with a through hole that cooperates with the anti-tilt bar.

[0008] More preferably, the filter layer can transmit blue-violet light or red light.

[0009] More preferably, the anti-tilt bar has a pipe fitting inside, one end of which has an internal thread, and the other end of which has an external thread that mates with the internal thread of the adjacent water inlet pipe.

[0010] More preferably, a tube cap is detachably connected to the external thread.

[0011] More preferably, the anti-roll bar is fitted with at least one limiting ring, and the lower part of the limiting ring is connected to at least one fixing rod for fixing the anti-roll bar to the ground.

[0012] More preferably, the anti-tilt bar is provided with a connecting pipe, which cooperates with the through hole, and the connecting pipe is used to connect the pipe fitting and the cover.

[0013] More preferably, the connecting pipe is connected to an annular limiting member that mates with the cover.

[0014] More preferably, the lower part of the connecting tube is provided with an L-shaped limiting member, the top of the L-shaped limiting member is connected to the connecting tube, and the other side of the L-shaped limiting member extends to the bottom of the cover.

[0015] The beneficial effects of this invention are as follows: After tobacco seedling transplantation, a cup cover is placed over the seedlings, providing a warm and moist environment that stimulates root growth and improves drought resistance. Simultaneously, the cup cover protects the seedlings from hail and rain, and blue-violet and red light also promotes seedling growth. Providing a warm and moist growing environment effectively protects the seedlings from natural disasters, and the specific spectrum promotes seedling growth, thereby improving drought resistance and survival rate, ensuring tobacco yield and quality.

[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 and Figure 2 As shown in Example 1, a multifunctional protective device for tobacco seedling transplantation includes an anti-tilting rod 1. At least one cover 9 is connected to the anti-tilting rod 1 for covering the transplanted tobacco seedlings. The cover 9 is a transparent or semi-transparent cup-shaped structure with a light-filtering layer. The cup-shaped cover 9 is made of transparent or semi-transparent polymer material, and its size is adapted to the size of the tobacco seedlings, completely covering them and providing them with independent growth space. The anti-tilting rod 1 and the cover 9 can work together to allow for the installation of multiple covers 9 according to actual needs, making it widely applicable. The light-filtering layer on the cover 9 effectively adjusts the light required for tobacco seedling growth, promoting seedling growth. After tobacco transplantation, the cup cover provides a warm and moist environment for the seedlings, stimulating root growth and improving their drought resistance. Simultaneously, the cup cover also protects the seedlings from hail and rain, and blue-violet and red light can also promote seedling growth.

[0022] In this embodiment, the top of the cover 9 is a hemispherical shell 10, and the lower part of the cover 9 is provided with an annular baffle 11. The lower part of the annular baffle 11 is provided with an insert plate 12 for fixing the cover 9 to the ground. The side wall of the cover 9 is provided with through holes that cooperate with the anti-tilt rod 1. The cover 9 is made of high-strength elastic material, which can effectively buffer the impact of hail and protect the tobacco seedlings from damage. The hemispherical shell 10 can guide rainwater to flow in all directions, preventing rainwater from directly impacting the tobacco seedlings, thus providing rain protection and preventing rainwater from accumulating on the top of the cover. It can comprehensively protect the tobacco seedlings from natural disasters such as hail and rain, reduce damage to the seedlings caused by environmental factors, and ensure the normal growth of the tobacco seedlings.

[0023] In this embodiment, the filter layer is transparent to blue-violet or red light, meaning the cover 9 is a transparent or semi-transparent blue-violet or red cup. The spectral adjustment layer is disposed on the outer surface of the cup body and is made of a material with selective spectral transmission function, its color being blue-violet or red. It selectively transmits blue-violet or red light, providing tobacco seedlings with a specific blue-violet or red light spectrum, filtering out other spectra that are detrimental to seedling growth, providing suitable light conditions for the seedlings, promoting photosynthesis and growth, and improving tobacco yield and quality.

[0024] like Figure 1 As shown in Embodiment 2, a multifunctional protective device for tobacco seedling transplanting includes a pipe fitting 2 inside the anti-tilt rod 1. One end of the pipe fitting 2 has an internal thread, and the other end has an external thread that mates with the internal thread of an adjacent water inlet pipe. The pipe fitting 2 can be connected to a water pipe or exposed to the air, supplying water or air to the tobacco seedlings inside the cover 9 through the pipe fitting 2, further achieving the heat preservation and moisture retention function of the cover 9. A pipe cap 3 is detachably connected to the external thread. The pipe cap 3 is used when supplying water to the tobacco seedlings inside the cover cup. At least one limiting ring 4 is fitted on the anti-tilt rod 1, and at least one fixing rod 5 is connected to the lower part of the limiting ring 4 to fix the anti-tilt rod 1 to the ground. The fixing rod 5 is used to fix the anti-tilt rod 1 to the ground to prevent the cover cup from shifting due to excessive wind or rain.

[0025] In this embodiment, the anti-tilt rod 1 is provided with a connecting pipe 6, which cooperates with the through hole and is used to connect the pipe fitting 2 and the cover 9. An annular limiting member 7 that cooperates with the cover 9 is connected to the connecting pipe 6. An L-shaped limiting member 8 is provided at the lower part of the connecting pipe 6, and a track hole is provided at the top of the L-shaped limiting member 8. The L-shaped limiting member 8 is slidably connected to the connecting pipe 6 through the track hole. The other side of the L-shaped limiting member 8 extends to the lower part of the cover 9, further protecting the cover 9. The connecting pipe 6 connects the pipe fitting 2 and the cover 9, allowing for the replenishment of water or air to the cover 9, thereby maintaining stable humidity inside the cup cover, providing a stable and suitable growth environment for the tobacco seedlings, effectively stimulating root growth, significantly improving the drought resistance of the tobacco seedlings, and increasing the survival rate after transplanting.

[0026] Specifically, when applying the multifunctional protective device of this invention to tobacco seedling transplanting, firstly, a cup-shaped cover of appropriate size is selected according to the size of the tobacco seedlings and placed over them after transplanting. In the event of hail or rain, the cover and anti-tilting rod provide protection for the seedlings. Simultaneously, the spectral adjustment layer transmits blue-violet or red light, providing the seedlings with light conditions that promote growth. The protective device can be removed once the seedlings have reached a certain growth stage.

[0027] All other structures are the same as in Example 1.

[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.
