Description

Technical Field

[0001] This application relates to the field of grain screening technology, and in particular to a device for separating whole soybean grains from broken soybean grains. Background Technology

[0002] During the harvesting, transportation, and processing of soybeans, broken soybean kernels are easily produced due to mechanical operation, friction, and collisions. The occurrence of these broken kernels is unavoidable, especially when using mechanical equipment for hulling, handling, or processing, where uneven stress or external impacts cause some soybeans to break. Broken soybean kernels not only affect product quality but also damage equipment during subsequent processing. Therefore, effectively separating whole soybean kernels from broken kernels is a crucial step in soybean processing.

[0003] Traditionally, separating whole soybean kernels from broken ones relies on manual sorting. This method is not only inefficient but also prone to omissions or inaccurate sorting, especially when processing large quantities of soybeans. Manual operation is time-consuming and labor-intensive, and cannot meet the needs of modern production. Utility Model Content

[0004] In order to achieve automated screening of whole soybean grains and broken soybean grains and improve screening efficiency, this application provides a separation device for whole soybean grains and broken soybean grains.

[0005] The present application provides a device for separating whole soybean grains from broken soybean grains, which adopts the following technical solution:

[0006] A device for separating whole soybean grains from broken soybean grains includes a first turntable and a second turntable. Both the first and second turntables have a plurality of sieve holes. The first and second turntables are coaxially arranged and connected by an adjusting member. The size and distribution of the sieve holes on the first turntable are the same as those on the second turntable. The adjusting member is used to adjust the relative angle between the first and second turntables, so that the sieve holes on the first and second turntables are in a one-to-one correspondence and overlapping / intersecting state. The second turntable is driven by a motor. The first turntable has protrusions to prevent broken soybean grains from being discharged from the edge of the first turntable. Whole soybean grains can pass over the protrusions under the centrifugal force of the first turntable.

[0007] By adopting the above technical solution, before screening, the adjusting component adjusts the relative positions of the first turntable and the second turntable so that the sieve holes of the first turntable and the sieve holes of the second turntable are in an intersecting state. At this time, whole soybean grains cannot pass through the space where the two sieve holes intersect, while most of the broken soybean grains can pass through the space where the two sieve holes intersect.

[0008] Soybeans are conveyed to the first turntable, and the first and second turntables rotate synchronously. Under the centrifugal force of the first turntable, whole soybean grains can pass over the protrusions and be discharged from the edge of the first turntable. The protrusions prevent broken soybean grains from being discharged from the edge of the first turntable, but the broken soybean grains can still roll and pass through the space where the two screen holes intersect, and be discharged from under the second turntable, thus completing the initial separation work.

[0009] Meanwhile, considering that some larger soybean fragments may not be able to pass through the space where the two screen holes intersect, after the initial screening, the relative positions of the first and second turntables are adjusted so that the screen holes of the first and second turntables overlap (at this point, the whole soybeans have been completely discharged from the first turntable). The first and second turntables are then rotated again, allowing the soybean fragments remaining on the first turntable to pass smoothly through the first and second turntables, completing the final separation. This greatly improves the separation efficiency, and the dual-stage screening design ensures that fragments of different sizes can be effectively separated, avoiding the problem of large fragments being retained, thereby improving the screening accuracy.

[0010] Optionally, the protrusion extends spirally along the surface of the first turntable and gradually expands toward the edge of the first turntable.

[0011] By adopting the above technical solution, the spiral protrusions can effectively prevent soybean fragments from rapidly reaching the edge of the turntable under centrifugal force, increasing their residence time above the screen holes. Furthermore, the spiral protrusions guide the movement path of the soybean fragments, allowing them to pass through more screen holes, thus giving them more opportunities to be discharged through the screen holes and separating more fragments during the initial screening process.

[0012] Optionally, the side of the protrusion facing the center of the first turntable is an arc surface, and the side of the protrusion away from the center of the first turntable is a vertical surface, with the top of the arc surface connecting to the top of the vertical surface.

[0013] By adopting the above technical solution, the arc-shaped surface design of the protrusion is relatively gentle, which can reduce the impact and friction of whole soybean grains when they come into contact with the protrusion, and reduce the risk of damage to soybean grains during the screening process.

[0014] Optionally, a plurality of the sieve holes of the first turntable are spirally distributed along the surface of the first turntable, and the further the sieve holes are from the center of the first turntable, the greater the distance between adjacent sieve holes.

[0015] When the sieve hole closest to its own center on the first turntable and the sieve hole closest to its own center on the second turntable intersect, the remaining sieve holes on the first turntable correspond one-to-one with the remaining sieve holes on the second turntable and intersect.

[0016] By adopting the above technical solution, this spiral distribution design makes the space of the intersecting screen holes larger as the distance from the center increases. The spiral distribution of the screen holes combined with the spiral design of the protrusions means that as the soybean crushed particles move outward, the space of the screen holes that can pass through gradually increases, which helps more soybean crushed particles to be separated during the screening process.

[0017] Moreover, due to the different sizes of the crushed particles, the spirally distributed screen design allows crushed particles of different sizes to be screened out separately when passing through the screen holes at different positions, reducing the possibility of large-sized soybean crushed particles remaining on the first turntable during the initial screening.

[0018] Optionally, the plurality of sieve holes of the first turntable are distributed in multiple rings along the surface of the first turntable, and each ring of sieve holes is concentric with the center of the first turntable, and the protrusion is arranged along the outer periphery of the first turntable and is in a ring shape.

[0019] By adopting the above technical solution, this design allows for more screen holes to be opened on the first turntable, and the space between the intersecting screen holes in each group can be kept the same. With the adjustment component, the relative positions of the first and second turntables can be adjusted to ensure that the size of the space between the intersecting screen holes in each group is the same. For soybeans of different sizes, the appropriate size of the intersecting space of the screen holes can be adjusted so that most of the broken soybean particles can pass through the first and second turntables during the initial screening. This is convenient for adjustment, and the design of more screen holes also helps to improve the separation effect.

[0020] Optionally, the adjusting component includes a fixing bolt, the first turntable has a first connecting hole, and the second turntable has a second connecting hole and a third connecting hole;

[0021] When the first connecting hole is opposite to the second connecting hole, the sieve holes of the first turntable correspond one-to-one with the sieve holes of the second turntable and coincide.

[0022] When the first connecting hole is opposite to the third connecting hole, the sieve holes of the second turntable correspond one-to-one with the sieve holes of the second turntable and intersect.

[0023] The fixing bolt passes through the second connecting hole / third connecting hole and the first connecting hole, and the fixing bolt is bolted to a fixing nut.

[0024] By adopting the above technical solution, the first connecting hole is aligned with the third connecting hole, and the first and second turntables are fixed with fixing bolts and fixing nuts to perform preliminary screening. The first connecting hole is aligned with the second connecting hole, and the first and second turntables are fixed with fixing bolts and fixing nuts to perform secondary screening, which is convenient for adjustment.

[0025] Optionally, a collection box is installed below the second turntable, the motor is installed inside the collection box, a plurality of first discharge ports are opened on the periphery of the collection box, and a sealing door for closing the first discharge ports is provided on the collection box.

[0026] By adopting the above technical solution, broken soybean grains can be collected into a collection box, and when taking out the broken soybean grains, all the closed doors can be opened to take out the broken soybean grains from multiple directions, which is convenient for cleaning.

[0027] Optionally, the first turntable is fitted with an annular sleeve, the upper surface of which is spiral-shaped, the lowest point of which is lower than the bottom surface of the first turntable, and a blocking part extending vertically upward along its circumference. The highest point of the blocking part is higher than the top surface of the first turntable, and the blocking part has a second discharge port, which corresponds to the lowest point of the upper surface of the annular sleeve.

[0028] By adopting the above technical solution, the whole soybean grains are separated from the first turntable and fall onto the upper surface of the annular sleeve. Then, the whole soybean grains roll along the upper surface of the annular sleeve and are uniformly discharged from the second discharge port, realizing the uniform collection of whole soybean grains. The shielding part prevents the whole soybean grains from falling off the edge of the annular sleeve during the rolling process.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. It enables automated screening of whole and broken soybean grains, improving screening efficiency. The dual-stage screening design ensures that broken grains of different sizes can be effectively separated, avoiding the problem of large broken grains being retained, thereby improving screening accuracy.

[0031] 2. The spiral protrusions can effectively prevent soybean fragments from quickly reaching the edge of the turntable under the action of centrifugal force, increasing their residence time above the screen holes. In addition, the spiral protrusions guide the movement path of the soybean fragments, allowing them to pass through more screen holes, thus giving them more opportunities to be discharged through the screen holes and separating more fragments during the initial screening process.

[0032] 3. The spiral distribution design of the sieve holes makes the space between the intersecting sieve holes increase with the distance from the center. The spiral distribution of the sieve holes, combined with the spiral design of the protrusions, allows the space of the sieve holes to gradually increase as the soybean crushed particles move outward, which helps to separate more soybean crushed particles during the screening process.

[0033] 4. Due to the different sizes of crushed particles, the spirally distributed screen design allows crushed particles of different sizes to be screened out separately when passing through the screen holes at different positions, reducing the possibility of large-sized soybean crushed particles remaining on the first rotating disc during the initial screening.

[0034] 5. The multi-ring distribution of sieve holes allows for more sieve holes on the first turntable, and ensures that the space between each group of sieve holes remains the same. With the adjustment mechanism, the relative positions of the first and second turntables can be adjusted to ensure that the size of the space between each group of sieve holes is the same. For soybeans of different sizes, the appropriate size of the sieve hole intersection space can be adjusted so that most of the broken soybean particles can pass through the first and second turntables during the initial screening. This design facilitates adjustment, and the increased number of sieve holes also helps to improve the separation effect. Attached Figure Description

[0043] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0044] Example 1

[0045] Embodiment 1 of this application discloses a device for separating whole soybean grains from broken soybean grains.

[0046] like Figure 1 , Figure 2 and Figure 3 The device for separating whole soybean kernels from broken kernels includes a collection box 1, which is cylindrical. Four first discharge ports 11 are equidistantly spaced along the circumference of the collection box 1. The collection box 1 is equipped with a sealing door 12 for closing the first discharge ports 11. A motor 2 is installed at the center of the collection box 1. The drive shaft of the motor 2 is coaxially connected to a second turntable 31, which is rotatably disposed within the collection box 1. The drive shaft of the motor 2 is coaxially rotatably connected to a first turntable 32, which is supported on the second turntable 31 and is rotatably disposed within the collection box 1.

[0047] The first turntable 32 and the second turntable 31 are connected by an adjusting member 4. Both the first turntable 32 and the second turntable 31 have a plurality of sieve holes 33. The size and distribution of the sieve holes 33 on the first turntable 32 are the same as those on the second turntable 31. The adjusting member 4 is used to adjust the relative angle between the first turntable 32 and the second turntable 31, so that the sieve holes 33 on the first turntable 32 and the sieve holes 33 on the second turntable 31 are in a one-to-one correspondence and overlapping / intersecting state. The first turntable 32 is provided with a protrusion 5 to prevent broken soybean particles from being discharged from the edge of the first turntable 32. Intact soybean particles can pass over the protrusion 5 under the centrifugal force of the first turntable 32.

[0048] like Figure 4 and Figure 5 In this embodiment of the application, the protrusion 5 extends spirally along the surface of the first turntable 32 and gradually expands toward the edge of the first turntable 32. The side of the protrusion 5 facing the center of the first turntable 32 is an arc surface, and the side of the protrusion 5 away from the center of the first turntable 32 is a vertical surface. The top of the arc surface is connected to the top of the vertical surface, that is, the longitudinal section of the protrusion 5 is fan-shaped.

[0049] The sieve holes 33 of the first turntable 32 are spirally distributed along the surface of the first turntable 32, and the farther the sieve holes 33 are from the center of the first turntable 32, the greater the distance between adjacent sieve holes 33, that is, the greater the distance between the centers of adjacent sieve holes 33.

[0050] When the screen hole 33 closest to its own center on the first turntable 32 and the screen hole 33 closest to its own center on the second turntable 31 are in an intersecting state, the remaining screen holes 33 on the first turntable 32 correspond one-to-one with the remaining screen holes 33 on the second turntable 31 and intersect. The intersecting space of each group of screen holes 33 increases as the distance from the center of the first turntable 32 increases.

[0051] When the screen hole 33 closest to its own center on the first turntable 32 and the screen hole 33 closest to its own center on the second turntable 31 are in a state of overlap, the remaining screen holes 33 on the first turntable 32 correspond one-to-one with and overlap with the remaining screen holes 33 on the second turntable 31.

[0052] like Figure 3 The adjusting component 4 includes a fixing bolt 41. The first turntable 32 has two first connecting holes 321, which are symmetrically arranged about the center of the first turntable 32. The second turntable 31 has two second connecting holes 311, which are symmetrically arranged about the center of the second turntable 31. The second turntable 31 also has two sets of third connecting holes 312, each set of third connecting holes 312 being adjacent to one of the second connecting holes 311, and the two sets of third connecting holes 312 being symmetrically arranged about the center of the second turntable 31. In each set of third connecting holes 312 in this embodiment, the number of third connecting holes 312 is two.

[0053] When the first connecting hole 321 is opposite to the second connecting hole 311, the sieve holes 33 of the first turntable 32 and the sieve holes 33 of the second turntable 31 correspond one-to-one and overlap.

[0054] When the first connecting hole 321 is opposite to the third connecting hole 312, the sieve holes 33 of the first turntable 32 and the sieve holes 33 of the second turntable 31 correspond one-to-one and intersect. When the first connecting hole 321 is opposite to different third connecting holes 312, the size of the intersecting space between the sieve holes 33 of the first turntable 32 and the sieve holes 33 of the second turntable 31 is different.

[0055] The fixing bolt 41 passes through the second connecting hole 311 / the third connecting hole 312 and the first connecting hole 321. The fixing bolt 41 is bolted to the fixing nut 42, which abuts against the first turntable 32 / the second turntable 31.

[0056] A ring sleeve 6 is fitted on the collection box 1. The ring sleeve 6 is fixedly connected to the collection box. The first turntable 32 is located inside the ring sleeve 6 and is coaxial. The upper surface of the ring sleeve 6 is set in a spiral shape. The highest point of the upper surface of the ring sleeve 6 is flush with the upper surface of the first turntable 32, and the lowest point of the upper surface of the ring sleeve 6 is lower than the bottom surface of the first turntable 32.

[0057] The annular sleeve 6 extends vertically upward along its circumference with a blocking part 61. The highest point of the blocking part 61 (i.e., the top surface of the blocking part 61) is higher than the top surface of the first turntable 32. The blocking part 61 has a second discharge port 611, which corresponds to the lowest point of the upper surface of the annular sleeve 6.

[0058] The thickness of the first turntable 32 and the second turntable 31 is 1mm-5mm to prevent whole soybean grains from getting stuck in the sieve holes 33. The height of the protrusion 5 is 5mm-1.5cm, ensuring that whole soybean grains can pass through the protrusion 5 smoothly while also blocking broken soybean grains.

[0059] The implementation principle of this application embodiment is as follows: Before separation, the first turntable 32 is rotated according to the size of the soybeans so that the first connecting hole 321 is aligned with one of the third connecting holes 312, and the first turntable 32 and the second turntable 31 are connected by using a through fixing bolt 41 and tightening a fixing nut 42.

[0060] At this time, the sieve holes 33 of the first turntable 32 and the sieve holes 33 of the second turntable 31 are in an intersecting state. At this time, whole soybean grains cannot pass through the space where the two sieve holes 33 intersect, while most of the broken soybean grains can pass through the space where the two sieve holes 33 intersect.

[0061] The soybeans are then conveyed to the first turntable 32 for preliminary screening. The first turntable 32 and the second turntable 31 rotate synchronously. Under the centrifugal force of the first turntable 32, the whole soybean grains can pass over the protrusion 5 and be discharged from the edge of the first turntable 32. They are then guided to the second discharge port 611 for unified discharge through the annular sleeve 6.

[0062] The protrusion 5 prevents broken soybean particles from being discharged from the edge of the first turntable 32, but the broken soybean particles can still roll and pass through the space where the two sieve holes 33 intersect, and be discharged from below the second turntable 31 into the collection box 1 for collection. Furthermore, the spiral protrusion 5 effectively prevents the broken soybean particles from rapidly reaching the edge of the turntable under centrifugal force, increasing their residence time above the sieve holes 33. The spiral protrusion 5 also guides the movement path of the broken soybean particles, allowing them to pass through more sieve holes 33, thus giving them a greater chance to be discharged through the sieve holes 33.

[0063] Meanwhile, the spiral distribution of the sieve holes 33 makes the space between the intersecting sieve holes 33 increase as the distance from the center increases. The spiral distribution of the sieve holes 33 combined with the spiral design of the protrusion 5 means that as the soybean crushed particles move outward, the space of the sieve holes 33 that can pass through gradually increases, which helps more soybean crushed particles to be separated into the collection box 1 during the screening process.

[0064] After the initial screening, considering that some larger soybean fragments may still be unable to pass through the space where the two screen holes 33 intersect, the relative positions of the first turntable 32 and the second turntable 31 are adjusted so that the first connecting hole 321 is aligned with the second connecting hole 311, and the first turntable 32 and the second turntable 31 are connected. At this time, the screen holes 33 of the first turntable 32 and the screen holes 33 of the second turntable 31 are in an overlapping state (at this time, the whole soybeans have been completely discharged from the first turntable 32). The first turntable 32 and the second turntable 31 are then rotated to allow the soybean fragments remaining on the first turntable 32 to pass smoothly through the first turntable 32 and the second turntable 31, completing the final separation work. This greatly improves the separation efficiency, and the dual-stage screening design ensures that fragments of different sizes can be effectively separated, avoiding the problem of large fragments being retained, thereby improving the screening accuracy.

[0065] Example 2

[0066] Reference Figure 6 and Figure 7 The difference between this embodiment and embodiment 1 is that the plurality of sieve holes 33 of the first turntable 32 are distributed in multiple rings along the surface of the first turntable 32, and each ring of sieve holes 33 is concentric with the center of the first turntable 32. The plurality of sieve holes 33 of the second turntable 31 are distributed in the same way as the sieve holes 33 of the first turntable 32. The protrusion 5 is arranged along the outer periphery of the first turntable 32 and is in the shape of a ring. All the sieve holes 33 are located within the ring-shaped protrusion 5.

[0067] The implementation principle of Example 2 is as follows: This design allows more sieve holes 33 to be opened on the first turntable 32, and the space between the intersection of each group of sieve holes 33 can be kept the same. With the adjustment component 4, the relative positions of the first turntable 32 and the second turntable 31 can be adjusted to ensure that the size of the space between the intersection of each group of sieve holes 33 is the same. For soybeans of different sizes, the appropriate size of the space between the sieve holes 33 can be adjusted so that most of the broken soybean particles can pass through the first turntable 32 and the second turntable 31 during the initial screening. Compared with Example 1, it is more convenient to adjust, and the design of more sieve holes 33 is also conducive to improving the separation effect.

[0068] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
