Technical Field
[0001] This utility model relates to the field of seed screening technology, and in particular to a seed screening device for agricultural technology promotion. Background Technology
[0002] Agricultural technology extension should promote the improvement and sustainable development of agricultural production. Seed screening equipment is needed in agricultural technology extension to facilitate the learning and practice of seed screening techniques. Seed screening is a key link in agricultural production to ensure seed quality and improve crop yield and quality. Its core purpose is to remove impurities, damaged, and weak seeds through physical or chemical methods, and retain plump, healthy seeds with high germination rates. Empty-shell seeds are often screened out using flotation technology, which is efficient, effective, easy to operate, and not limited by equipment.
[0003] Previous seed screening equipment for agricultural technology extension has the following drawbacks: 1. It mostly involves adding water to the seeds for flotation, requiring manual turning of the seeds, which is time-consuming and labor-intensive, and cannot collect empty seeds after screening. Therefore, those skilled in the art have provided a seed screening device for agricultural technology extension to solve the problems mentioned in the background. Utility Model Content
[0004] The main objective of this invention is to provide a seed screening device for agricultural technology promotion, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An agricultural technology promotion seed screening device includes a base, an outer cylinder, a mesh cylinder, and a sealed top cover;
[0007] The base has an outer cylinder mounted on top with screws, and a mesh cylinder is fitted inside the outer cylinder. A cylinder locking cover is mounted on the top periphery of the mesh cylinder with screws. The cylinder locking cover is locked onto the top of the outer cylinder. An annular flow groove is mounted on the top of the cylinder locking cover with screws. A communication port is opened on the inner side of the annular flow groove. A sealing top cover is locked onto the top of the inner side wall of the annular flow groove. A geared motor is mounted on the top center of the sealing top cover via a mounting base. The output shaft of the geared motor passes through the sealing top cover and is connected to a stirring shaft via a coupling. Stirring blades are mounted at equal intervals around the periphery of the stirring shaft with screws.
[0008] As a further improvement of this utility model: a liquid filling pipe is provided on the top of the sealing top cover and on the side of the reduction motor, and a liquid filling valve is provided on the liquid filling pipe.
[0009] As a further improvement of this utility model, a feeding port is provided on the top of the sealing top cover and on the other side of the reduction motor.
[0010] As a further improvement of this utility model: an outlet is provided on one side of the annular flow channel and the outlet is located away from the connecting port. The outlet is set at a height lower than the connecting port. Empty wheat or rice enters the annular flow channel from the connecting port along with the liquid. The outlet being lower than the connecting port prevents liquid backflow.
[0011] As a further improvement of this utility model: the outer cylinder has an external thread on its top periphery and the inner wall of the cylinder locking cover has a corresponding internal thread. By unscrewing the cylinder locking cover from the top of the outer cylinder, the mesh cylinder can be removed, making it easier to clean out the seeds inside.
[0012] As a further improvement of this utility model: a discharge pipe is provided on one side of the bottom end of the outer cylinder, and a discharge valve is provided on the discharge pipe.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. Add the wheat or rice seeds to be screened into the mesh cylinder through the feeding port. Open the liquid adding valve and add water into the mesh cylinder through the liquid adding pipe. The water passes through the mesh cylinder and enters the outer cylinder. Use the geared motor to drive the stirring blades on the stirring shaft to rotate at a constant speed, which facilitates the turning of the seeds. Empty wheat or rice husks float to the surface of the liquid. Continue to add water. As the liquid level rises to the connecting port, the empty wheat or rice husks enter the annular flow channel through the connecting port with the liquid and finally flow out from the outlet for easy collection.
[0015] 2. After screening, open the discharge valve and discharge the waste liquid after screening through the discharge pipe. Open and remove the sealed top cover, unscrew the cylinder cover from the top of the outer cylinder, and take out the screen cylinder to facilitate cleaning out the seeds inside. The agricultural technology promotion seed screening equipment can automatically turn the seeds, float out empty shell seeds, automatically collect empty shell seeds, and thoroughly clean good seeds.

[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] Please see Figure 1-3 In this embodiment of the present invention, an agricultural technology promotion seed screening device includes a base 1, an outer cylinder 4, a mesh cylinder 17 and a sealed top cover 10.
[0022] An outer cylinder 4 is screwed onto the top of the base 1, and a mesh cylinder 17 is fitted inside the outer cylinder 4. A cylinder locking cover 12 is screwed onto the top periphery of the mesh cylinder 17, and the cylinder locking cover 12 is locked onto the top of the outer cylinder 4. An annular flow groove 11 is screwed onto the top of the cylinder locking cover 12, and a connecting port 16 is opened on the inner side of the annular flow groove 11. A sealing top cover 10 is locked onto the top of the inner ring side wall of the annular flow groove 11. A geared motor 8 is installed at the top center of the sealing top cover 10 through a mounting seat. The output shaft of the geared motor 8 passes through the sealing top cover 10 and is connected to a stirring shaft 14 through a coupling. Stirring blades 15 are installed at equal intervals around the periphery of the stirring shaft 14 through screws.

[0028] The working principle of this utility model is as follows: Wheat or rice seeds to be screened are added into the mesh cylinder 17 through the feeding port 9. The liquid adding valve 6 is opened, and water is added into the mesh cylinder 17 through the liquid adding pipe 7. The water passes through the mesh cylinder 17 into the outer cylinder 4. The geared motor 8 drives the stirring blades 15 on the stirring shaft 14 to rotate at a uniform speed, facilitating the turning of the seeds. Empty wheat or rice husks float to the surface of the liquid. Water is added continuously, and as the liquid level rises to the connecting port 16, the empty wheat or rice husks enter the annular flow channel 11 through the connecting port 16, and finally flow out from the outlet 5 for centralized collection. After screening, the discharge valve 3 is opened, and the waste liquid after screening is discharged through the discharge pipe 2. The sealing top cover 10 is opened and removed, and the cylinder locking cover 12 is unscrewed from the top of the outer cylinder 4. The mesh cylinder 17 is then removed, facilitating the cleaning of the seeds inside. This agricultural technology promotion seed screening equipment automatically turns and floats the seeds, automatically collects the empty husks, and thoroughly cleans the good seeds.
