Description

Technical Field

[0001] This utility model relates to the field of cotton breeding technology, specifically to a cotton breeding stigma sleeve. Background Technology

[0002] Cotton is the seed fiber of plants in the genus Gossypium of the Malvaceae family, native to subtropical regions. To ensure high cotton yields, cotton breeding is generally carried out. In cotton breeding, stigma tubes are often used to prevent the influence of self-pollination. Currently, stigma tubes are often used by covering the stigma with straws or beverage cans. Since these straws or beverage cans are open, they are generally not sealed with caps, allowing pollen from the outside to affect the stigma through the opening, further impacting cotton yield. Furthermore, the gap between the tube and the stigma also allows for self-pollination.

[0003] To address this issue, a cotton breeding stigma sleeve was designed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the sealing issues of existing stigma sleeves, this invention provides a cotton breeding stigma sleeve that can seal not only the upper part of the stigma but also the lower part.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a cotton breeding stigma sleeve, including a tube body, a tube cover at the top of the tube body, the tube cover being an airbag structure, the tube cover being connected to the tube body through a sealing ring, an airbag being provided in an annular shape at the upper part of the tube body, and the airbag being disposed through the tube body, one of the airbags being provided with a connecting tube, and a sealing structure being provided at the lower end of the tube body.

[0008] As an improvement, the tube body has a structure that is wider at the top and narrower at the bottom.

[0009] As an improvement, the sealing structure includes a lower sealing end sleeved on the bottom end of the tube body, the lower sealing end having a through hole, a sealing ring on the lower sealing end, and the lower sealing end being a soft structure.

[0010] As an improvement, the airbag is provided with an air inlet, and a valve is provided inside the air inlet.

[0011] As an improvement, the top of the tube body is also provided with an upper connecting end, and the diameter of the upper connecting end is larger than that of the tube body. The bottom of the tube cover is provided with a connecting end, which is sleeved on the upper connecting end, and a sealing ring is provided at the connection between the connecting end and the tube cover.

[0012] As an improvement, a protective pad is provided on the inner wall of the tube.

[0013] The advantages of this invention compared to existing technologies are as follows: by connecting the tube cover, the lower sealing end, and the tube body, a double sealing effect is achieved at both ends of the stigma sleeve. It has strong applicability, is easy to operate, will not damage the stigma during use, and has a good sealing effect on the stigma, improving the stigma isolation effect, effectively preventing cross-pollination, and improving the purity of breeding.

[0018] 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.

[0019] The technical background of this application fully explains the problems of the prior art, and there are no overarching or general issues. The following utility model content and specific embodiments describe in detail the problems that this application needs to solve, clarify the technical problems that the technical solution needs to solve, and determine that the technical solution of this application has beneficial effects compared with the objective prior art.

[0020] Please see Figures 1-3 One embodiment provided by this utility model:

[0021] A cotton breeding stigma sleeve includes a tube body 1, which has a structure that is wider at the top and narrower at the bottom, which is conducive to fitting the cotton stigma and at the same time prevents the tube body 1 from damaging the surface of the stem; a protective pad 10 is provided on the inner wall of the tube body 1 to protect the cotton stigma.

[0022] The tube body 1 is equipped with a tube cover 2 at the top. The tube cover 2 is an airbag structure that can automatically expand by the insertion of gas. The tube cover 2 is connected to the tube body 1 through a sealing ring 9. The upper part of the tube body 1 is equipped with an airbag 5 in a ring, and the airbag 5 is set inside the tube body 1. The airbag 5 is equipped with an air inlet 6, and a valve is provided inside the air inlet 6 to facilitate the inflation of the airbag 5. One of the airbags 5 is equipped with a connecting tube 7 to facilitate the input of gas into the tube cover 2. As the cotton stigma grows larger, the tube cover 2 can also grow larger to avoid affecting the space for the growth of the cotton stigma.

[0023] The lower end of the tube body 1 is provided with a sealing structure, which includes a lower sealing end 3 sleeved on the bottom end of the tube body 1. The lower sealing end 3 is provided with a through hole 301. The through hole 301 is used to sleeve the cotton column head and the tube body 1. The lower sealing end 3 is provided with a sealing ring 4. The lower sealing end 3 is made of a soft structure so that the sealing ring 4 can tighten the lower sealing end 3 to achieve a sealing effect on the lower end of the tube body 1.

[0024] The top of the tube body 1 is also provided with an upper connecting end 8, and the diameter of the upper connecting end 8 is larger than that of the tube body 1. The bottom of the tube cover 2 is provided with a connecting end 201, which is fitted onto the upper connecting end 8, and a sealing ring 209 is provided at the connection between the connecting end 201 and the tube cover 2.

[0025] In practical use, the above structure is first fitted onto the cotton stigma from bottom to top, with the lower connecting end, tube 1, and tube cover 2 inserted. Each air bladder is inflated through the air inlet, making the air bladder tangent to the cotton stigma. The air bladders, surrounding the cotton stigma, clamp it, preventing tube 1 from sliding down. A sealing ring 9 is used to seal the lower sealing end. One air bladder is connected to the tube cover via a connecting tube. Inflating the air bladder allows the gas inside to enter the tube cover 2, causing it to expand and maximizing the space for the cotton stigma. This eliminates the need for workers to replace different sized tube covers as the cotton stigma grows, offering strong applicability, convenient operation, good stigma sealing, and no need for replacement. It effectively prevents cross-pollination and improves breeding purity.

[0026] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope of this application is indicated by the claims.

[0027] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The embodiments of this application described above do not constitute a limitation on the scope of protection of this application.
