The bean sorting device 1 according to the present invention is basically a device for sorting and separating beans, such as peanuts, peas, beans, and red beans, as well as various grains, based on their size.

As is widely known, peanut, which is a seed of a dicotyledonous plant having two cotyledons, may be split in half when an impact is applied. In some cases, it is necessary to use only whole peanuts (2a), and in some cases it does not matter if split peanuts (2b) are used. work may be required.

The bean sorting apparatus 1 of the present invention can be widely used for size-based sorting of whole grains including beans, but is particularly suitable for sorting whole peanuts (2a) and half peanuts (2b), Hereinafter, the case where the bean sorting device 1 of the present invention is applied to the sorting of whole peanuts and half peanuts will be mainly described.

As shown in FIGS. 1 to 13, the bean sorting device 1 according to the present invention includes a sorting barrel 10, a support frame 20, a sorting barrel driving mechanism 30, and a bean extraction mechanism 40. include

Hereinafter, other components except for the head removal mechanism 40 will be described with reference to Patent No. 10-2222668 of the present inventor.

The sorting cylinder 10 is, as exemplarily shown in Figs. 1 to 4 and 9, a cylindrical rotating member with an empty inside and open upstream and downstream, and a plurality of sorting rings 12 with a plurality of connection-stirring plates 13 .

Each of the sorting rings 12 is, for example, a ring in which a steel rod having a circular cross section is formed in a circular annular shape (annular), and these sorting rings 12 are in the form of rings of the same size between adjacent sorting rings. By arranging tens to hundreds or more in parallel in the up-and-down direction so as to have a sorting gap 11 of

The selection gap 11 is, for example, narrower than the diameter of the whole peanut 2a and wider than the remaining radius of the half peanut 2b. The size of the selection gap 11 is the size of the peanut to be screened. It is appropriately set according to the , for example, it can be set to about 6-7mm.

The connection-stirring arm 13 is, as shown in FIGS. 6, 7 and 9, by connecting the sorting rings 12 in the up-and-down direction on the inner circumferential surface, the whole sorting rings 12 are formed in the sorting gap ( 11) to be integrally bound into one barrel while maintaining the state, and by repeatedly lifting and dropping the peanuts 2 in the sorting ring 12 when the sorting barrel 10 rotates, agitating the peanuts is the absence of

That is, the connection-stirring arm 13 strongly connects the sorting rings 12 as a whole so as to have the shape of the sorting barrel 10 in a state in which the sorting rings 12 are arranged at uniform intervals (sorting gap). In addition, when selecting the peanuts 2 while rotating the sorting barrel 10, by stirring the peanuts, the selection speed and the selection rate of peanuts are improved.

In the illustrated embodiment, with the sorting gap 11 maintained between the sorting rings 12, in the sorting ring 12 of 360 degrees, Fig. 4 shows four connecting-stirrs at an angle of 90 degrees 13) is connected, FIG. 9 is an example of connecting six connecting-stirring bars 13 at an angle of 60 degrees, and connecting-stirring bars 13 are 3, 5, 7 and 8 Dogs and the like can also be applied.

In the illustrated embodiment, the connecting-stirring bars 13 are welded to the inner circumferential surface of the sorting rings 12 while transversely traversing a plurality of sorting rings 12 arranged in parallel, thereby forming the entire sorting ring 12 . are combined into a single barrel.

4, 6, 7 and 9 and the like, the connecting-stirring arm 13 can be formed of an elongated large-shaped member having a cross-sectional shape of a gyratory.

Giyeokja-shaped connection-stirring bar 13, the transverse portion 13a acts as a connecting bar connecting the sorting rings 12.

In the horizontal portion 13a acting as a connecting rod, the number of protrusions 14a corresponding to the sorting ring 12 and the number of recessed portions 14b corresponding to the extraction rotation body 41 of the head removal mechanism 40 are alternately arranged. can be formed continuously.

A sorting ring 12 is welded to the protruding protrusion 14a, and the concave recessed portion 14b allows the extraction rotating body 41 of the head extraction mechanism 40 to be inserted.

By forming the protrusions 14a and recesses 14b on the connecting-stirring arm 13, the sorting rings 12 can be more easily welded to the connecting-stirring arm 13, and the entire sorting gap ( 11) can be uniformly formed, and the insertion of the extraction rotating body 41 of the head extraction mechanism 40 into the selection gap 11 is not hindered by the connection-stirring arm 13 .

In the gyeokja-shaped connection-stirring table 13, the vertical portion 13b is, as shown in Figs. 4, 6, 7 and 9, when the sorting barrel 10 rotates, the horizontal portion 13a ), acts as a stirrer to stir the peanuts by lifting the peanuts 2 in the sorting ring 12 upwards and dropping them downwards.

That is, when the sorting barrel 10 rotates, the peanut is placed on it when the connection-stirring arm 13 is in a low position, and the connection-stirring arm 13 is raised to a high position so that the peanuts fall down. , Peanuts (2) are continuously stirred while the sorting barrel (10) is rotating.

Although the peanuts are also stirred by the rotation of the sorting barrel 10, the peanuts are further stirred by the connection-stirring arm 13, whereby the half peanuts 2b fall through the sorting gap 11. speed can be improved.

The support frame 20 is a frame in which the sorting tube 10 is rotatably installed in an inclined state such that the downstream is lower than the upstream.

The support frame 20 includes an upper support plate 21 and a lower support plate 23 as shown in FIGS. 1 and 2 .

The upper support plate 21 is a plate-shaped member that closes and supports the upstream end of the sorting container 10, and a bean supply unit 22 for supplying peanuts to the upstream of the sorting container 10 may be formed. .

In the illustrated embodiment, a funnel-shaped supply hopper 22a is formed as the bean supply part 22 on the upper side of the upper support plate 21, and when peanuts are put into the supply hopper 22a, the input peanuts are separated into a sorting container ( 10) is supplied upstream.

An opening/closing door 22b is installed in the supply hopper 22a, so that only when the opening/closing door 22b is opened, the peanuts in the supply hopper 22a can be supplied to the sorting container 10.

The lower support plate 23 is a plate-shaped member that closes and supports the downstream end of the sorting container 10, so that the whole peanuts 2a selected without falling are discharged from the downstream of the sorting container 10 to the outside. It is possible to form an outlet 24 that does.

An inclined discharge plate 25 and a discharge door 26 may be installed in the discharge port 24 .

The inclined discharge plate 25 is a plate formed inclined so that the peanuts to be discharged can slide down into a container (not shown) disposed below it.

As exemplarily shown in FIGS. 2 and 8 , the discharge door 26 may be opened and closed by installing a hinge 26a on the upper portion.

In a state in which the discharge door 26 is fully opened, the peanuts reaching the discharge port 24 are discharged to the discharge port 24 without delay.

The open state of the discharge door 26 can be maintained by attaching it to the magnet 26b or by hooking it with a ring (not shown).

The closed state of the discharge door 26 may be maintained by its own weight.

The discharge door 26, which is closed by its own weight, is not dropped and the peanuts collected in the discharge port 24 are pushed and opened by the load trying to flow down downstream, so the peanuts arriving at the discharge port 24 are not discharged immediately. , is discharged after the delay as much as the self-weight of the discharge door 26 resists.

Preventing the peanuts from being discharged directly to the outlet 24 slows down the sorting speed slightly, but increases the sorting rate of half peanuts.

A hook 26d on which the weight 26c can be hung may be formed on the discharge door 26, thereby adjusting the weight of the discharge door 26 by the weight of the weight 26c mounted on the hook 26d. and consequently, it is possible to control the degree to which the peanut is retarded at the outlet (24).

That is, if the weight of the weight 26c mounted on the discharge door 26 is increased, the lag time becomes longer and the sorting speed is relatively slowed, but the sorting rate is increased. have.

The structure in which the sorting barrel 10 is inclined so that the downstream is lower than the upstream is not particularly limited, and the embodiment illustrated in FIGS. 1 to 3 includes the upstream leg 27a of the support frame 20 as the downstream leg. (27b) This is an example in which the sorting tube 10 is rotatably installed on the support frame 20 in a state that is inclined by the height difference of the legs in a state formed higher than (27b).

The illustrated embodiment is approximately 1,700 mm long and 450 mm in diameter, the sorting barrel 10, the height difference is 150 mm, a support having an upstream leg (27a) of 1,100 mm in height and a downstream leg (27b) of 950 mm in height. It is illustrated on the assumption that the frame 20 is installed at an angle, but is not limited thereto.

The larger the inclination of the sorting barrel 10, the faster the peanuts flow from the upstream to the downstream.

A height adjustment mechanism 28 may be formed on the upstream leg 27a and/or the downstream leg 27b to adjust the inclination of the sorting barrel 10 .

In the illustrated embodiment, the upstream leg ( 27a) shows an example of adjusting the inclination of the sorting barrel 10 by forming, but is not limited thereto. The height adjustment mechanism 28 may be formed on the downstream leg 27b.

By installing wheels 29 at the lower ends of the upstream and downstream legs 27a and 27b, the pulse sorting device according to the present invention can be conveniently moved.

According to the bean sorting device according to the present invention as described above, the peanut (2) in which the half peanut (2b) and the whole peanut (2a) are mixed is put into the supply hopper (22a) of the support frame (20), and the opening and closing door (22b) ) is opened, the peanuts slowly flow down from the upstream to the downstream while being stirred in the sorting barrel 10 rotating in an inclined state, and are further stirred by the connection-stirring bar 13, in this process the sorting gap ( 11) The half peanut 2b having a smaller radius falls down through the sorting gap 11 and is accommodated in the container 3 below, and the whole peanut 2a having a larger diameter than the sorting gap gradually flows downstream It flows down and is collected at the outlet 24, and eventually the load of the collected peanuts pushes open the discharge door 26 closed by its own weight, falls through the inclined discharge plate 25, and a container (not shown) under it. ), the whole peanut (2) is sorted into half peanuts (2b) and whole peanuts (2a).

The sorting barrel driving mechanism 30 is installed on the support frame 20 to provide power to rotate the sorting barrel 10 .

It may include a pulley 32 , a driven pulley 33 installed on the sorting barrel rotating shaft 15 , and a belt 34 caught between the driving pulley 32 and the driven pulley 33 .

The sorting barrel driving mechanism 30 applied to the present invention is not particularly limited as long as it is a mechanism capable of rotating the sorting barrel 10 at an appropriate speed other than the illustrated embodiment.

In the process of sorting peanuts with the bean sorting device 1 according to the present invention, it may occur that the peanuts 2 are unintentionally caught in the sorting gap 11, and peanuts caught in the sorting gap 11 in this way. can reduce the sorting speed and sorting rate of peanuts by impeding the flow and sorting of other peanuts. Even if the sorting speed is not reduced, the sorting operation is completed only when the peanuts caught in the sorting gap are removed.

Against this background, as shown in FIGS. 1 to 3 and 9 to 13 , the bean sorting device 1 of the present invention is a bean for pushing out peanuts (beans: 2) caught in the sorting gap 11 . and a withdrawal mechanism (40).

The head extraction mechanism 40 includes a extraction rotation body 41 , a extraction rotation shaft 42 , a bearing bracket 43 , and a extraction motor 44 .

The pull-out rotating body 41 is a plate-shaped member having a thickness and a diameter that can rotate while being inserted into the selection gap 11 . A number corresponding to the number of the selection gaps 11 of the selection cylinder 10 is applied to the subtraction rotation body 41 .

Around the outer periphery of the subtractive rotation body 41, which is a portion in direct contact with the peanut 2 sandwiched in the selection gap 11, as shown exemplarily in FIG. By forming a, by increasing the frictional resistance with the peanut, it is possible to more effectively remove the peanut caught in the selection gap (11).

Around the outer periphery of the pull-out rotation body 41, which is a portion in direct contact with the peanut 2 sandwiched in the sorting gap 11, a brush 41b is formed, as exemplarily shown in FIG. 11) It can remove the peanuts stuck in it more effectively.

Concave-convex rotation body 41 formed with irregularities (41a) may be suitable when selecting a hard-tissue peanut, and the brush (41b) is formed with-out rotation body 41 may be suitable when selecting a soft-tissue peanut. have.

The subtraction rotation shaft 42 is an axis formed to cross the center of the subtraction rotation bodies 41 so that the entire subtraction rotation bodies 41 can rotate integrally. Therefore, when the subtraction rotation shaft 42 is rotated, the entire subtraction rotation body 41 is rotated integrally.

The bearing bracket 43 is a member installed on the upper support plate 21 and the lower support plate 23, respectively, and the pull-out rotation shaft 42 is rotatably installed on the bearing brackets 43 on both sides, for this purpose Each bearing bracket 43 is provided with a bearing 43a, and the pull-out rotation shaft 42 is rotatably supported by both bearings 43a.

The bearing bracket 43 is not fixedly provided to the upper support plate 21 and the lower support plate 23 , but is provided so as to be movable and fixed in the radial direction of the sorting cylinder 10 .

Therefore, by moving and fixing the bearing bracket 43 in the radial direction of the sorting cylinder 10 as much as desired, the insertion depth of the extraction rotating body 41 into the sorting gap 11 can be adjusted.

Each bearing bracket 43 may include an inner piece 43b, an outer piece 43c and a fixing bolt 43e.

The inner piece 43b is located inside the upper support plate 21 or the lower support plate 23 while the bearing 43a is formed.

The outer piece 43c is, in a state integrally connected to the inner piece 43b, located outside the upper support plate 21 or the lower support plate 23, on the outer surface of the upper support plate 21 or the lower support plate 23 It is movably inserted into the formed guide piece (43g).

The fixing bolt 43e is a bolt for fixing the outer piece 43c to the guide piece 43g.

In the illustrated embodiment, two slots 43d are formed through the outer piece 43c, and the fixing bolt 43e is fastened through the slot 43d, so when the fixing bolt 43e is loosened, the outer piece 43c) can be moved with respect to the guide piece 43g, and by tightening the fixing bolt 43e, the outer piece 43c can be firmly fixed to the guide piece 43g.

As shown in Figure 12 and the like, a second fixing bolt 43f can be added between the guide piece 43g and the outer piece 43c, and the second fixing bolt 43f is the outer piece for the guide piece 43g (43g). 43c) to make the fixed state more robust.

In this way, the insertion depth of the subtractive rotation body 41 for the selection gap 11 can be adjusted according to the size of the peanuts to be screened or the state of the peanuts caught in the selection gap 11, for example, the peanuts in the selection gap ( 11), the insertion depth of the pull-out rotation body 41 may be set to be deep in the state of being strongly fitted, and the insertion depth may be set low in the state of being lightly fitted.

The subtraction motor 44 is an electric motor for rotating the subtraction rotating bodies 41 through the subtraction rotation shaft 42 as shown in FIGS. 10, 11 and 13 . The installation position of the extraction motor 44 is not particularly limited, and the illustrated specific example is an example in which the extraction motor 44 is installed on the bearing bracket 43 on one side.

The structure for rotating the subtraction rotation shaft 42 with the subtraction motor 44 is not particularly limited, and for example, a driving gear 44a is installed in the subtraction motor 44, and a driven gear ( 42a) is provided, and the rolling chain 44b is hung between the driving gear 44a and the driven gear 42a, so that the extraction rotation shaft 42 can be rotated by the extraction motor 44.

According to the bean extracting mechanism 40, when the peanut 2 is caught in the sorting gap 11 during the sorting process, it is inserted into the sorting gap 11 and rotates by the extracting motor 44 ( 41) can effectively push out the peanuts caught in the sorting gap 11 while driving along the sorting gap 11 of the rotating sorting barrel 10 .

Since the pull-out rotation shaft 42 installed between the bearing brackets 43 is a member with a fairly long length, its middle part may sag by an external force or its own weight, and thus the selection gap ( Although the insertion depth of the subtraction rotation body 41 for 11) is set to a specific depth, the specific insertion depth may not be maintained at a specific position (eg, the middle part) of the subtraction rotation shaft 42 .

Against this background, in order to more precisely maintain the insertion depth of the subtraction rotating body 41 with respect to the sorting gap 11, the pulse sorting device 1 according to the present invention is exemplarily shown in Figs. As described above, it may further include a support 45 and a binding bolt 46 .

The support 45 is a support member in the form of a rod having high rigidity, which is installed between a pair of bearing brackets 43 in parallel (parallel) to the subtractive rotation shaft 42 .

The binding bolt 46 is a bolt for binding the subtractive rotation shaft 42 to the support 45, and may include a bearing 46a and an adjustment nut 46b.

The bearing (46a) formed at the lower end of the binding bolt (46) rotatably constrains the subtractive rotation shaft (42).

The adjusting nut 46b fastened to the upper side of the binding bolt 46 is loosened and tightened with respect to the binding bolt 46, thereby adjusting the interval between the support 45 and the subtracting rotation shaft 42.

The binding bolt 46 is, for example, installed in the middle of the support 45, or, for example, installed in two places dividing the support 45 into three equal parts as shown in FIG. 10, or as shown in FIG. 45) can be installed in three places dividing it into 4 equal parts, and at least one can be installed.

As described above, the distance between the support 45 and the subtraction rotation shaft 42 can be adjusted by the adjustment nut 46b as well as binding the subtraction rotary shaft 42 to the support 45 by the binding bolt 46 as described above. Accordingly, by the bearing bracket 43, the insertion depth of the extraction rotation body 41 for a specific selection gap 11 can be uniformly maintained over the entire length of the extraction rotation shaft 42, and, if necessary, the extraction rotation body 41 ) can be set differently for each section.

The support frame 20 of the bean separator 1 of the present invention is provided with a power switch, a rotation speed control switch of the sorting tube 10, and a rotation speed control switch of the extraction rotary shaft 42, in a suitable position for operation. A control panel (not shown) can be installed, and the control of the device by the control panel is not directly related to the features of the present invention, and techniques known in the related art can be applied according to the present invention, so a detailed description thereof is omitted. do.

According to the present invention, when various beans including peanuts and further various grains are selected, the size of the selection target may vary, and the selection gap 11 must be set according to the selection target.
