Description

Technical Field

[0001] The utility model relates to the field of cotton breeding and cultivation, in particular to a simple device for quantitatively screening cotton seeds. Background Art

[0002] In agricultural production and experiments, seed screening and obtaining a specific number of seeds are crucial links, especially for cotton seeds. When conducting experimental treatments, field planting and yield prediction, a certain number of seeds need to be obtained quickly. Hundred-grain weight and thousand-grain weight are important indicators of seed size and fullness. They are the content of seed quality inspection and crop seed testing, and are also an important basis for field yield prediction. However, it may be difficult to quickly obtain a fixed number of cotton seeds for the same variety of cotton due to uneven germplasm and irregular shapes. Effective seed screening tools can improve seed screening quality, experimental efficiency, and quickly obtain a fixed number of cotton seeds for subsequent cotton hundred-grain weight and thousand-grain weight measurements.

[0003] Current seed screening usually uses traditional manual or machine-vibration-based methods, which have certain limitations in efficiency and accuracy and it is difficult to obtain a specific number of seeds for subsequent experiments, resulting in poor results. Utility Model Content

[0004] In view of the problems and shortcomings existing in the above-mentioned prior art, the purpose of the utility model is to provide a simple device for quantitatively screening cotton seeds, which solves the problems of inconsistent germplasm, time-consuming and labor-intensive problems caused by subjectivity when manually counting a certain number of cotton seeds in laboratories and field work.

[0005] In order to achieve the above invention purpose, the technical solution adopted by the utility model is: a simple quantitative cotton seed screening device, including a sieve body, the front and rear sides of the sieve body are symmetrically provided with rectangular grooves near the sieve plate, the right side is provided with a discharge port, and the sieve holes of the bottom sieve plate are connected with a storage bag; the rectangular grooves are interspersed with strips.

[0006] The pick is a cylinder with a length of 8.8 cm and a diameter of 0.2 cm.

[0007] The sieve plate of the sieve body is a square with a side length of 8 cm, and is provided with 100 fixed number of sieve holes with a diameter of 0.7 cm, and is made of transparent plastic material.

[0008] The discharge port is in the shape of an arc table, with a lower bottom surface of 5.4 cm in length and an upper bottom surface of 2 cm in length.

[0009] Compared with the prior art, the utility model quantitative screening cotton seed device has the following advantages:

[0010] 1. The utility model adopts an integrated design, which is easy to carry and suitable for various scenes in laboratories, fields and outdoors. It has a reasonable structure and is easy to operate. Through the coordination of the strip and the discharge port, it can quickly remove excess cotton seeds;

[0011] 2. The storage structure of the utility model has upper and lower screening openings, and cotton seeds with poor quality and inappropriate size cannot be stored in the storage structure. Therefore, the utility model can be used to sort cotton seed germplasm;

[0012] 3. The storage structure of the utility model is made of transparent plastic, so the status of the cotton seeds can be clearly seen, ensuring that the user can observe the storage status of the cotton seeds in the storage structure at any time;

[0013] 4. The storage structure of the utility model has an opening at the bottom, through which one can see whether there are cotton seeds in the storage structure, thus ensuring that a fixed amount of cotton seeds can be obtained at one time;

[0014] 5. The utility model has a fixed number (100) of openings, through which a certain number of cotton seeds can be quickly obtained for subsequent 100-grain weight and 1,000-grain weight measurements. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clear, the implementation methods of the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Figure 1 and Figure 2 A schematic structural diagram of a simple quantitative cotton seed screening device of the utility model is given from the perspectives of a top view and a side view, respectively, comprising a sieve body 3, wherein rectangular grooves 5 are symmetrically provided at the front and rear sides of the sieve body 3 near the sieve plate, a discharge port 2 is provided on the right side, and a storage bag 4 is connected to the sieve holes of the bottom sieve plate; and a shifting bar 1 is inserted in the rectangular groove 5.

[0020] The lever 1 is a cylindrical structure with a length of 8.8 cm and a diameter of 0.2 cm.

[0021] The sieve plate of the sieve body 3 is a square with a side length of 8 cm, and is provided with 100 fixed number of sieve holes with a diameter of 0.7 cm, and is made of transparent plastic material.

[0022] The discharge port 2 is in the shape of an arc table, with a lower bottom surface of 5.4 cm in length and an upper bottom surface of 2 cm in length.

[0023] The specific use method of the simple quantitative cotton seed screening device of the utility model is as follows:

[0024] First, a certain amount of cotton seeds of required varieties are poured into the sieve body 3 . The sieve body 3 is surrounded by vertical boundary plates, so the cotton seeds will be retained on the sieve body 3 .

[0025] The cotton seeds are allowed to fall into the storage bag 4 by shaking or the like, and the cotton seeds are observed from the side and the lower opening of the storage bag 4 to ensure that there are cotton seeds in each storage unit.

[0026] The picking bar 1 is moved parallelly from the leftmost end to the rightmost end, and the cotton seeds except the storage bag 4 are poured out through the discharge port 2.

[0027] Make sure that there is no extra cotton seeds on the sieve body 3 except the storage bag 4, and observe the storage bag 4 from below or from the side again to ensure that a fixed amount of cotton seeds are contained therein.

[0028] The utility model is placed on a table or tilted to take out the cotton seeds in the storage bag 4, and then the pick 1 is moved parallel to the left from the leftmost end to the rightmost end again to ensure that the cotton seeds in the storage bag 4 are poured out from the discharge port 2. The utility model can also be directly inverted on a plane to obtain 100 cotton seeds that meet certain requirements.

[0029] The utility model discloses a simple quantitative cotton seed screening device, which realizes the rapid screening and sorting of cotton seeds through a series of design optimizations. The application of the device will help to shorten the time for obtaining a specific number of cotton seeds.
