Description
Technical Field
[0001] The utility model relates to a screening device, in particular to a high-quality soybean seed screening device. Background Art
[0002] Soybean is an annual herbaceous plant and the most important legume in the world. The currently cultivated soybean is evolved from wild soybean through long-term directional selection and improvement and domestication. The soybean plant is 30-90 cm tall, and the protein content of soybean is 35%-40%. Genetically modified soybean: round. The leaves usually have 3 leaflets; the petiole is 2-20 cm long; there are 2-5 seeds, elliptical or nearly spherical, with smooth seed coat, and various colors such as light green, yellow, brown and black. The flowering period is from June to July, and the fruiting period is from July to September. It is native to China, cultivated throughout China, and also widely cultivated around the world. Soybean is one of the important food crops in China, with a cultivation history of 5,000 years. It was called shu in ancient times. The main producing area is in Northeast China. It is a crop whose seeds are rich in plant protein. Soybean is most commonly used to make various soy products, extract soybean oil, brew soy sauce and extract protein.
[0003] In order to ensure the quality of soybeans, sowing after screening out high-quality soybean seeds through seed screening can effectively improve the quality of soybeans. One of the methods of seed screening in the prior art is to place the sieve at a slope of about 30°, and utilize the inertial effect of the seeds rolling and sliding down, which not only plays the role of sliding seed selection, but also uses the gap between two iron wires to screen small seeds, weed seeds smaller than soybean seeds, broken half grains, shriveled grains, sediment, etc. into the bottom of the sieve, and selects high-quality seeds that are large, plump and neat, improving the seed quality.
[0004] In the prior art, soybean seeds are screened by tilting the sieve and then utilizing the inertial effect of the soybean seeds rolling and sliding down. In this method, only screening can be carried out according to the size of the seeds. If larger bad seeds fall in, they are very likely not to be screened out, reducing the quality of soybean seeds. During the screening process, because the sieve is in an inclined state, when the seeds are poured into the screening port, some soybean seeds may fly off the sieve onto the ground, resulting in incomplete screening and the need to pick them up manually and put them back for re-screening, reducing the work efficiency.
[0005] Therefore, it is necessary to design a high-quality soybean seed screening device to solve the above technical problems. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] The following describes the embodiments of the utility model with reference to the accompanying drawings.
[0025] Embodiment: A high-quality soybean seed screening device, as Figures 1 - 8As shown in the figure, it includes a material distribution frame 1, a sealing frame 2, a blanking hopper 3, a material distribution fan 7, a screening component, a blowing component, a vibrating component and a collection component. There are 3 material distribution openings at the top of the material distribution frame 1. The two material distribution openings on the left side of the material distribution frame 1 are inclined at 60°. There are 3 discharging grooves on the front and rear sides of the material distribution frame 1. The top of the material distribution frame 1 is connected to the sealing frame 2 by welding. There is a handle on the upper right side of the sealing frame 2. The right side of the top of the sealing frame 2 is connected and communicated with the blanking hopper 3. A material distribution fan 7 is rotatably connected inside the blanking hopper 3. A screening component is arranged at the bottom inside the sealing frame 2. A blowing component is arranged at the top inside the sealing frame 2. The vibrating component is arranged between the blowing component and the screening component. A collection component is arranged inside the material distribution frame 1.
[0026] As Figure 2 , Figure 3 , Figure 5 and Figure 7 shown, the screening component includes a screening frame 4, a first screen 5 and a second screen 6. The screening frame 4 is slidably placed on the top of the material distribution frame 1 and slides inside the sealing frame 2. The screening frame 4 is located at the bottom inside the sealing frame 2. A first screen 5 is fixedly arranged on the right part of the screening frame 4. A second screen 6 is fixedly arranged on the left part of the screening frame 4. The material falling holes of the first screen 5 are smaller and denser than those of the second screen 6. The first screen 5 and the second screen 6 correspond to the two material distribution openings on the left side of the top of the material distribution frame 1.
[0027] As Figure 3 , Figure 6 and Figure 7 shown, the blowing component includes an air cylinder 8, a motor 9 and an impeller 10. The air cylinder 8 is connected to the top inside the sealing frame 2 by welding. Ventilation openings are arranged on both the front and rear sides of the air cylinder 8, and the ventilation openings of the air cylinder 8 are communicated with the sealing frame 2. A blowing opening is arranged at the lower right side of the air cylinder 8. A motor 9 is connected to the rear side inside the air cylinder 8 by bolts. An impeller 10 is connected to the output shaft of the motor 9 by welding.
[0028] Start the motor 9. The motor 9 drives the impeller 10 to rotate counterclockwise. As the impeller 10 rotates, the airflow is inhaled into the interior of the air duct 8 from the ventilation openings on both sides of the sealing frame 2, and then blown out from the blowing port at the lower right of the air duct 8. The blowing port of the air duct 8 faces the bottom of the feeding hopper 3. Then, pour the soybean seeds to be screened from the feeding hopper 3. The soybean seeds will fall batch by batch from one side of the material distributing fan 7. Subsequently, the airflow in the air duct 8 will blow the lighter bad soybean seeds, weed seeds, and empty grains from left to right into the discharging chute at the rightmost of the material distributing frame 1 and fall into the waste frame 16. Under the action of gravity, the heavier soybean seeds will continue to fall onto the screening frame 4. These heavier soybean seeds will first fall onto the first screen 5. The first screen 5 screens out the smaller soybean seeds and sifts them into the first material frame 17 at the bottom of the net. The first material frame 17 collects good soybean seeds. The remaining larger soybean seeds will fall into the second material frame 18 at the bottom of the second screen 6. The second material frame 18 collects high-quality soybean seeds. In this way, the soybean seeds are classified. After all the soybeans are classified, turn off the motor 9, and the impeller 10 and the belt 11 will stop rotating accordingly. The screening frame 4 returns to its original position, and the spring 14 is compressed, that is, it returns to the initial state.
[0029] As Figure 6 and Figure 7 shown, the material shaking assembly includes a belt 11, a material shaking rod 12, a limit block 13, and a spring 14. There is a convex block on the front side of the impeller 10. The front inner wall of the sealing frame 2 is connected with the limit block 13 by welding. The material shaking rod 12 is slidably connected to the limit block 13. The belt 11 is wound between the convex block on the impeller 10 and the material shaking rod 12. The bottom of the material shaking rod 12 is connected to the screening frame 4 by bolts. A guiding groove is opened on the rear inner wall of the sealing frame 2, and the screening frame 4 slides in the guiding groove of the sealing frame 2. A spring 14 is connected between the guiding groove of the sealing frame 2 and the screening frame 4.
[0030] When screening soybean seeds is required, push the handle on the upper right of the sealing frame 2 to move the device to the horizontal ground at the working location. First, start the motor 9 to drive the impeller 10 to blow the light bad seeds and miscellaneous materials into the discharging chute at the rightmost of the material distributing frame 1. Then, screen out the good soybean seeds through the first screen 5 and sift them into the first material frame 17. After that, screen out the high-quality soybean seeds through the second screen 6 and sift them into the second material frame 18. Start the motor 9. The output shaft of the motor 9 drives the impeller 10 to rotate counterclockwise. The impeller 10 rotates counterclockwise by 180°. While rotating, it pulls the belt 11 to move upward. Then the belt 11 makes the material shaking rod 12 slide upward, and the screening frame 4 moves upward to stretch and deform the spring 14. When the impeller 10 rotates counterclockwise by 180° again, the screening frame 4 and the material shaking rod 12 move downward under the action of the spring 14, making the belt 11 in a taut state between the material shaking rod 12 and the convex block. Repeating this can achieve the up and down movement of the screening frame 4, achieving the effect of quickly classifying soybean seeds by shaking.
[0031] As Figure 1 and Figure 8 shown, the collection component includes a material baffle net 15, a waste material box 16, a first material box 17 and a second material box 18. The discharge chute of the material distribution box 1 is slidably connected with the waste material box 16, the first material box 17 and the second material box 18 in sequence from right to left. The material baffle nets 15 are connected to the positions above the waste material box 16, the first material box 17 and the second material box 18 on the front and rear side walls of the material distribution box 1. The material baffle nets 15 respectively block the gaps between the waste material box 16, the first material box 17 and the second material box 18 and the material distribution box 1.
[0032] When a certain amount is collected, the material discharge situation inside the material distribution box 1 can be observed through the material baffle net 15. When the waste material box 16, the first material box 17 and the second material box 18 are about to be filled up, the material discharge is stopped. Then, the handles corresponding to the front sides of the waste material box 16, the first material box 17 and the second material box 18 are pulled forward. After the materials in the waste material box 16, the first material box 17 and the second material box 18 are poured out, they are pushed backward and returned to their original positions to continue collection.
[0033] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
