DETAILED DESCRIPTION OF THE INVENTION
【Example】
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings. In this hull sorter, the front part of the fuselage (1) has a crab dripping part (A). An oscillating sorting unit that arranges a suction wind selection unit (B) for wind-selecting crocodile at the rear of the sliding unit (A), and sorts mixed rice behind the suction wind selection unit (B). (C) is provided to constitute a swing type rice hull sorter.
[0006]
The sliding part (A) includes a dredging tank (14) and a pair of de-rolling rolls (15), and the like to slid off the dredging falling from within the dredging tank (14), and to remove the sludge. (15) Grain retention part (3) which is received by the downflow ridge (2) obliquely arranged below (15) and the suction wind selection part (B) flows down to the crocodile and has a curved bottom at the middle of the downflow ridge (2). ) In the grain retaining part (3), and a jumping blade (7) that is attached to a rotating shaft (13) orthogonal to the flow-down direction of the sliding object is provided, and the sloping upwardly facing jumping path (16) To the secondary wind selection path (5) of the suction wind selection section (B), which will be described later.
[0007]
The suction wind selection unit (B) is provided with a suction dust exhaust fan (6) at the upper part, and the upper part of the falling slag (2) is sandwiched between the grain retention unit (3) and the suction dust exhaust fan (6). The primary wind lane (4) and secondary wind lane (5), where the wings and lower wings are back-to-back from the wings, are erected in a backward-tilted state. Is connected to the horizontal mixed rice feed rod (17) installed side by side, and provided with a straw take-out path (12) on the rear side of the upper part of the secondary wind selector (5), and below the straw take-out path (12) A horizontal feed rod (18) is installed horizontally. In addition, (19) and (20) are air inlets formed by meshes.
[0008]
That is, the fallen objects flowing down the downflow culvert (2) were removed by sucking and discharging the husks in the slidable sludge by the suction air rising in the primary air selection path (4) from the air intake port (19). Afterwards, brown rice, rice bran, rice cake, etc. enter the grain retention part (3) and are ejected obliquely upward to the secondary wind selection path (5) by the jumping blade (7) and rise from the air suction port (20) The mixed rice of brown rice and rice bran flows into the mixed rice horizontal feed rod (17), and the rice cake falls from the rice cake take-out route (12) to the horizontal rice feed rod (18) and is discharged from the rice cake discharge rod (21). Taken out.
[0009]
The secondary wind selection path (5) meanders, and the impact of what is jumped by the jumping blade (7) in the middle of the rear wall (8) forming the wind selection path (5) A surface (9) is formed, and a turning surface (11) for changing the direction rearward is formed on the upper portion of the front wall (10).
[0010]
As a result, as shown in FIG. 2, the thing that is jumped to the secondary wind path (5) as indicated by the arrow (c) by the jumping blade (7) collides with the impact surface (9). And the heavy brown rice and rice cake fall like (e) and flow into the mixed rice horizontal feeding rice cake (17), and the relatively light rice cake containing dust comes from the brown rice and rice cake by the rising suction wind Separate and rise like (f). And this rising thing is changed direction back like (G) by the turning surface (11), so that the soot leaves the working area of the ascending wind and is separated from the dust, soot take-out path (12) The dust is sucked into the suction dust exhaust fan (6) together with the suction air and discharged outside the apparatus.
[0011]
The swing sorting unit (C) stacks the mixed rice in the mixed rice tank (22) in several stages and supports it with a link and swings the sorting rice (23). In this case, the mixed rice of swaying cradle and swaying sardine is screened with the mixed rice of brown rice and sardine drifting to the middle part of swaying and swaying sway.
[0012]
That is, the mixed rice that has been laterally fed through the mixed rice horizontal feeding trough (17) and lifted to the mixed rice tank (22) by the mixed rice drawer (24) is swung through each sorter (23). From the brown rice partition plate (25), the brown rice zone (a) is brown rice, and from the straw partition plate (26), the brown rice zone (b) is straw. In addition, the mixed rice flows out from the mixed rice zone (c) between the brown rice partition plate (25) and the straw partition plate (26) to be sorted.
[0013]
(27) is a brown rice bran that receives what flows out of the brown rice zone (a), and (28) is the opposite of the one connected to the falling rice bran (2) of the mixed rice horizontal feeding trough (17). In the mixed rice cereal board connected to the container, the rice from the mixed rice zone (c) is received, returned to the mixed rice cross feed (17), lifted by the mixed rice thrower (24), and reselected. What flows out from the soot zone (b) is returned to the soot tank (14) by the soot reduction (30) from the soot (29) and re-depleted.
[0014]
The brown rice bran (27) is connected to and connected to the mixed rice cereal board (28), and a drop opening (31) is opened near the connection portion of the brown rice bran (27). ) Is formed in the shape of a small V-shaped brown rice-style selection chamber (32), and the brown rice-style selection chamber (32) and the brown rice bran (27) communicate with each other via a drop opening (31). The switching plate (33) is attached to the mouth (31) so as to be able to rise and fall, and the dropping port (31) is opened and closed by overturning by the standing operation of the switching plate (33).
[0015]
In addition, an air inlet (34) is opened in the rear wall of the fuselage (1) and the switching plate (33) is opened, so that outside air is sucked from the air inlet (34) and the brown rice wind selection chamber (32). Forming an outside air suction air passage (35) through which the starting end of the secondary air selection passage (5) is directed to the wrinkle through the drop opening (31), blown up through the mixed rice cereal plate (28), The raising / lowering operation of the switching plate (33) is performed by the back-and-forth movement operation of the switching lever (36) mounted on the side of the dredge tank (14).
[0016]
In addition, (37) is a shutter-opening / closing shutter lever of the straw tank (14), (38) is an outlet opening at the bottom of the brown rice-style selection chamber (32), and (39) is a brown rice slot. .
[0017]
Therefore, at the start or near the end of the hulling operation, when the switching lever (36) is operated to fall the switching plate (33) and close the drop opening (31), the brown rice zone (a ) Flows out of the brown rice bran (27), is taken over by the mixed rice cereal plate (28), flows into the mixed rice cross feed (17), circulates in the machine, and is sorted by the sorter (23). When the switching plate (33) is raised by the switching lever (36), the dropping port (31) opens and the brown rice flowing down the brown rice bran (27) falls into the brown rice-style selection chamber (32). The dust contained in the brown rice is sucked into the secondary air selection passage (5) of the suction air selection section (B) through the dropping port (31) together with the suction air by the suction air flowing through the outside air suction air passage (35). Then, the finished brown rice from which the dust is removed from the suction dust exhaust fan (6) is removed from the outlet (38 Retrieved in place by (39) - outflow rice Surowa from.
[0018]
Next, the details of the jumping blade (7) provided in the grain retaining portion (3) will be described with reference to FIGS. 6 and 7. The jumping blade (7) has a base portion (7a) and a tip portion. Divided into wrinkles (7b), the two base portions (7a) are fastened to the peripheral surface of the rotating shaft (13) by fixing bolts (41) inserted into the long holes (40), and are axially attached to each other. The leading edge (7b), which has a protruding base portion and is divided into a flange (7a), is rotatably connected by a hinge (42).
[0019]
Both the base wing (7a) and the tip wing (7b) are made of iron plate as a plate body, and the base wing (7b) is hinged to the base wand (7a). By attaching the connecting pin (42a) of the hinge (42) to a position where the trailing surface (43) with respect to the rotational direction (b) of the hook (7a) is slightly retracted from the tip of the hook (7b), the tip (7b) ) Is rotated linearly in the direction opposite to the direction of rotation (A) with the connecting pin (42a) as an axis, and the tip end (7b) has the base at the base. The fold (7a) is bent and retracted, and the position of the connecting pin (42a) is slightly retracted from the tip of the trailing surface (43) of the base wing (7a). As a result, the tip end (44) of the base wing (7a) is rotated from the straight state. They are prevented from excessive rotation in the direction (A) side.
[0020]
As a result, the brown rice, rice bran, rice bran, and the like that have flowed into the grain retaining portion (3) become a straight state in which the tip wrinkle (7b) extends from the base wrinkle (7a) by the rotational centrifugal force, and the ejection path (16). To the secondary wind path (5).
[0021]
At this time, if foreign matter such as pebbles is mixed in the jumping object, the tip (7b) is rotated in the direction opposite to the rotation direction as indicated by the phantom line (h) by the impact of the foreign matter. After the retreat, the retraction is restored to the original state by the rotating centrifugal force and the jump is continued.
[0022]
FIG. 8 shows another embodiment of the jumping blade (7). The base part (7a) is extended from the rotating shaft (13) and the base part (7a) is rotated (b). , And the tip (7b) is connected to the hinge (42) so as to be rotatable only in the direction opposite to the direction of rotation (A) in the same manner as described above. I tried to retreat like this.
[0023]
Then, even if the leading edge (7b) is retracted due to the impact of a foreign object, since the rotation locus (b) of the base edge (7a) is large, the jumping action does not extremely decrease.
[0024]
【The invention's effect】
The present invention is implemented in the form described above, and has the following effects.
[0025]
That is, the rear is arranged respectively suction air election unit for winnowing the crocodile sliding落物front of the aircraft by providing a crocodile paddy sliding penetration point, a suction air election portion communicating cereal to suction dust-exhaust fan A primary wind selection path and a secondary wind selection path that separate the upper and lower hands of the grain retention part are provided, and a jump blade that jumps toward the secondary wind selection path is provided in the grain retention part, and meanders. In the wind-screening device of the hull sorter for which the rear wall of the secondary wind path is the impact surface of the mixed rice that has jumped and the air path is changed to the upper part of the front wall. Sliding object wind in which the base that is pivotally attached to the arm is divided into wrinkles and the tip that is made up of a jumping plate made of iron plate, and the tip that the base portion is divided into wrinkles is connected to the swivel in a direction opposite to the rotation direction. Since the selection device is used, the impact of the pebbles and other foreign matter mixed in the slid-off object when it jumps will cause the blade tip to rotate in the opposite direction and the base will retreat. Ragi deformation or damage does not occur, it is possible to produce recoil the slide落物in springing and significant drop is prevented without unevenness in the state of action.
