Description

[Detailed description of the invention]

INDUSTRIAL APPLICATION FIELD The present invention relates to a rice hulling and sorting device. A prior art hulling device is always equipped with a device for separating paddy and brown rice. This separating device is a mangoku or swinging type brown rice separating device, and the mangoku is made up of a simple wire mesh, and the swinging type brown rice separating device is structured so that a board made of a rough surface is swingable. Wanshi is just a wire mesh, so it is extremely light and usually
It is integrated into the rice hulling section. The performance of the swing-type paddy/brown rice separator is several steps superior to that of Mangoku, but the structure of the swing-type paddy/brown rice separator is extremely labor-intensive due to its structure of swinging a metal plate, and it is difficult to assemble it integrally with the huller. Since, normally,
Place them side by side on the floor. In addition, in JP-A-49, a husking-type paddy/brown rice separator was swingably mounted above the hulling chamber, and an elevator was attached to the side of the hulling chamber to reach the separating device. -91846
In this device, the separator is attached to the suction section above the separator by having its upper end pivoted to the lower end of a hook rod, and the upper end of the hook rod is attached to the upper end bearing portion of the hook rod. The suction part supporting the can be moved up and down. For this reason, a member is required to support the separation device above the separation device, which increases the height of the hulling and sorting device, causing the center of gravity to be located above, which deteriorates the vibration stability of the hulling and sorting device. At the same time, the sorting action is adversely affected, the upper surface of the sorting plate becomes difficult to see due to the above-mentioned member, and when adjusting the inclination of the sorting plate, the inclination of the hook rod also changes, and the swing angle changes at the same time as the inclination angle, making the adjustment delicate. , which has the disadvantage of being difficult to operate. Furthermore, there is a device known as Utility Model Publication No. 38-15060 in which the supporting plate of the swinging sorting board is moved up and down via the machine frame by moving the support frame of the swinging sorter up and down. In order to move objects up and down the entire heavy machine frame,
Not only is a large amount of force required, but changes in the inclination of the machine frame change the inclination of the movable support plate relative to the horizontal plane, which changes the swinging angle of the swinging sorting board, making it difficult to adjust its inclination. There are drawbacks. In order to deal with this, the oscillating grain sorting device is pivotally supported on the upper end of the support rod whose lower end is pivotally supported.

[At the same time, the lower end of one of the support rods is fixed to the floor so as to be movable up and down, and the lower end of the other support rod is fixed to the floor, thereby connecting the floor and the oscillating grain sorting device. An eccentric connection having an eccentric device at one end was proposed as JP-A-49-107840. However, none of these methods takes into account the effect of changes in the slope of the swinging paddy/brown rice device on the grain lifting machine that supplies mixed grains of paddy/brown rice to the swinging paddy/brown rice separator. Met. Purpose of the Invention The present invention eliminates the above-mentioned drawbacks and provides a separating device support member below the separating device, thereby lowering the center of gravity of the hulling and sorting device and increasing its stability against vibrations, thereby making the sorting action stable and accurate. At the same time, the top surface of the sorting plate is made easy to see so that the sorting action can be controlled at all times.The machine frame, which is the wind sorting chamber, remains fixed and the axis can be moved up and down with respect to this wind sorting chamber. The inclination of the swing type paddy/brown rice separator relative to the wind selection chamber can be changed with a small force by raising and lowering the hook rod that is fixed to the shaft. The three-point link formed by the shaft stopping point of the arm, the other hook rod for the swing type paddy/brown rice separation device, and the arm shaft stopping point changes the angle of the hook rod relative to the winnowing chamber. This not only allows the swinging type paddy/brown rice separator to change only its tilt angle without changing its swing angle, making it easy to adjust, but also allows for easy adjustment of By fixing the lower end to the vertically movable shaft, there is little change in the positional relationship between the discharge part of the brown rice grain mixture of the elevator and the inflow part of the brown rice grain mixture of the swinging type paddy/brown rice separator. A mixture of brown rice and paddy grains is always supplied to the rocking type paddy brown rice fraction 11 in an approximately even state from the oscillating type paddy/brown rice separation device, and the grain separation of brown rice grains can be carried out accurately and stably. The purpose is to provide a device. Structure of the Invention The present invention comprises a hulling room, a wind-selection room, a swing-type paddy/brown rice separation device that is swingably mounted above this room, and a side of the wind-selection room. In the rice hulling sorting device, the separating device has a lower end thereof pivoted to a hook rod near the elevator and an upper end of a hook rod far from the elevator. At the same time, the lower end of the hook rod farthest from the elevator is fixed to a shaft that can move up and down with respect to the wind selection chamber, and the lower end of the other hook rod closer to the elevator is fixed to the shaft that is movable up and down with respect to the wind selection chamber. The present invention is characterized in that the wind selection chamber and the swinging type paddy/brown rice separator are connected to each other by an arm having an eccentric device at one end thereof.

There are many possible configurations for this, but in the configuration shown in FIG. A shaft 31' is provided above the shaft 31'.
A vertical movement adjustment rod 28 is mounted between the top 68 attached to the top 68, and a bearing 25 is installed at a position slightly apart from the bearing 27.
The vertically movable rod 26, which is mounted between the shafts 31 and 31', is mounted on the bearing 25 by a shaft 29, and when the threaded rod 67 is rotated, the movable rod 26 moves around the shaft 29. It is centered and moves alternately like a seesaw. Although FIG. 10 is a different embodiment from the structure shown in FIG. 3, the principle is the same, and a perspective view of the main part is shown in FIG. '11. To explain this configuration, it is possible to use a bank. One end of the movable rod 2G is directly attached to a shaft 17 that pivots the hook rod 16, and the aforementioned shaft 31 is mounted on the extension side of the movable rod 26, and the lower end of the hook rod 30 is attached to the shaft 31. 768°68 in FIG.

That is, the receivers 64 are provided on the left and right sides respectively, and the number of stages is variable. Board surface of the separation device 18 5. /l preferably has a rough, rough surface made by pressing a metal plate, H is the supply side, 1- is the discharge side, l-11 is the swinging side, and the discharge side is
Then, the brown rice outlet 50 is placed oddly on the upper side 1→1 side, and the paddy brown rice outlet L]52 is placed on the lower side L1.
A mixed rice outlet 51 is provided in the middle (see FIG. 8). Stepped transfer gutter 55, 56, 57 whose bottom surface is a stepped transfer gutter are integrally attached to each takeout [I], and each boundary of each takeout [I] is provided with an adjustment plate 61.
63 are provided respectively. The adjustment plate 61 is adjustable in the direction of the arrow in FIG. 8, and as shown in FIGS. A flow plate 62 with a smooth surface is integrally attached to the side. When the adjustment plate 61 moves to the left side in the figure as shown in FIG. 6, the right end of the flow plate 62 will be located above the right end of the stepped transfer gutter 57, but at this time, the flow will flow to the left side from the adjustment plate 61. All of the grains flowed into the step-shaped transfer gutter 56 below, and even if the adjustment plate 61 was extremely shifted to the left in the figure as shown in FIG. The grains are all fed into the stepped transfer trough 57 by the action of the stepped auxiliary transfer plate 57'. In FIG. 8, 58 is a brown rice discharge gutter, 59 is a mixed rice discharge gutter, 60 is a paddy rice discharge gutter, and 72 is a rubber cover for safety. Board surface 54 made of the rough surface
As shown in FIG. 9, the required number of stages is polymerized. Then, take the receiving frames 64, 64 that stand upright on both sides (=
Jt], the board surfaces 54 are overlapped so that the desired number of stages is formed between the receiving frames 64, 64, and the bolts 66 are tightened from the left and right sides to fix them. The reason why the board surfaces 54 are polymerized one after another in this way is to match the efficiency of the rubber roll. In other words, the efficiency of the hull removal performed on the rubber rolls 5, 5 and the above-mentioned amount I! Since the efficiency of separation by the IIt device 18 must be perfectly matched with the efficiency of the IIt device 18, sufficient operation and effect will not be achieved. It is beautifully constructed. In FIG. 3, (j649 is a distributing device C that distributes grains to the board surfaces 54 of each stage stacked vertically. 1 is fixed to the side part of the supply hopper 4, but the middle part is tightened by the clamping fitting 37 using the supply hopper 4.The structure shown clearly in FIG. The connection 1138 is fixed, one end is fixed to the connection piece 38 with a screw 4o, and the other end is tightened with a screw 42. 39° 41 is a bent part provided for threading. In this way, the rice-hulling machine 33 is connected to the rice grain selection chamber 1 by the lower part with the metal fitting 34 and the upper part by the tightening metal fitting 37.
is fixed to. An adjustment hopper 43 is suspended from the F part of the elevator @33 via a link 44.4.5 so as to be able to move up and down. The small adjustment collar 43 has a built-in spring mechanism so as to move up and down according to the storage depth, and is moved upward by the elasticity of the spring and lowered by the weight of the grain. The adjustment hopper 43 is provided with a protrusion 46, one end of which is connected to the other end of the wire A1-47 connected to the adjustment valve 48 marked +ffr. 65 is an independent plate, 71 is a mixed rice receiving trough, and 73 is a trough for overflow f. Hull is removed by 5, 5, and wind-selected from the droplet 6.
It flows down into 7. Since suction air from the suction blower 3 is blown across the wind selection chamber 7, light rice husks are suctioned, enter the suction blower 1'' through the suction port 14, and are removed from the system. On the other hand, the unhulled brown rice and unhulled rice and paddy grains of the FF [human brown rice and unhulled grains] fall directly onto the first gutter 10, are transported in the front and back direction by the first screw 9, and are sent to the ¥1 disembarking machine 33. The liquid flows into the upper part, moves up and down the elevator a133, and then is stored in the adjustment hopper 43. Since the adjustment hopper 43 is configured to be raised by the elasticity of the spring and lowered depending on the weight of the grain, it descends according to the storage area of grain in the adjustment hopper 43. Links 44 and 45 is adjustment hopper 4
Write down the instructions for vertical movement in step 3. When the adjustment hopper 43 moves downward, the other end of the protruding piece 46 moves downward, so the one end 47, whose one end is fixed to the protruding piece 46, is pulled up. wire 47
It acts so as not to close the control valve 48 attached to the other end.In other words, if the amount stored in the control hopper 43 becomes more than the planned m, the flow will no longer flow from the supply hopper 4. The grains in the regulating hopper 43 are configured so that a certain amount of the grain mixture continuously flows into the distribution device 49. Therefore, a certain amount of the mixture of brown rice grains continuously flows into the distribution device 49 and is distributed. After that, the board surface 5 consisting of independent boards 65 in each stage

(t is subjected to the sorting action in the direction of the W arrow. Zunawa) 5.
When the rotating shaft 21 rotates, the eccentric 23 rotates, and the upper end of the arm 24 causes the shaft 19 to move back and forth in the left-right direction.
Since it is mounted at an angle of about 5 degrees to the right, the movement of the support 19 (same for the shaft 32) is an oblique up and down reciprocating movement when viewed from the front as indicated by the W arrow. Therefore, the board surface 54 is composed of a rough surface,
Since it is a reciprocating motion of rocking in the W direction, looking at the flow of grain on the board surface 54, as shown in FIG. The small rice grains flow along the swinging side L1 in a flow E3L, and in the middle, the unseparated mixed grains flow out in a flow E2L/, respectively, to respective outlet ports 50.degree. 51.52. This separation device′
Stepped transfer troughs 55, 56, and 57 are installed at each outlet 50, 51, and 52 of 1B.
The brown rice is gradually transferred through the stepped transfer gutter 57, and is taken out of the system from the unloaded brown rice JJl drain gutter 58, which is attached to the end. The mixed grains are returned to the supply hopper 4 by the paddy brown rice takeout tiII 160 and mixed into the raw material again, and after flowing like the E2 line, the mixed grains are transferred by the step-like transfer gutter 56, and from the mixed rice takeout 111159. The mixed rice flows into the mixed rice receiving trough 71, the lower connection port J, and the first rice receiving trough 1.
0 and undergoes the re-sorting action. On the other hand, the separation device f
Due to its performance characteristics, ffi'18 sometimes does not match the amount of hulling done by Cole 5, 5, but in such a station, the board 54 consisting of an independent board 65 can be increased or decreased. Make that adjustment. The minute 1ull device 18 is of a multi-stage type as in the embodiment, and is reciprocated in the W direction by 1 no., which causes a considerable reaction.However, in the present invention, the above-mentioned Attach the balance 22 to the rotating shaft 21.
This reduces the reaction force considerably. Therefore, the distribution of the grains falling on the plate surface 54 of the separator 18 is ensured to be uniformly distributed over the entire surface. For this purpose, it is necessary to make the swinging side L1 considerably lower than the swinging upper side L1, and it is necessary to adjust the height of this swinging side L1. This adjustment is performed using the screw rod 67 or (:1, first
This is done by adjusting the screw rod 67 shown in Fig. 0.'1J, that is,
When the threaded rod 67 is rotated in FIG. 3, the shaft 31' moves vertically, so the vertically movable rod 26 moves like a seesaw around the shaft 29, and the shaft 31 on the reaction side moves. - Since it is done manually, the swinging side E1 moves up and down, and the horizontal inclination when viewed from the front is adjusted 11i'i. In the case of the embodiment shown in FIG. 10, the lateral inclination is adjusted by directly moving the shaft 31 up and down, and when the screw 1167 is turned, the points 768 and 68 of h) move closer to each other or move apart. Therefore, the upper shaft 31 is rotated in the vertical direction, thereby adjusting the inclination of the board surface 54. Effects of the Invention The present invention is constructed as described above, and in particular, the lit selection chamber, which is the machine frame, remains fixed.
By moving the shaft up and down with respect to the chamber, and by raising and lowering the hook rod fixed to the shaft, it is possible to change the inclination of the swing type paddy brown rice separating device with a small force with respect to the wind sorting chamber. A three-point link is formed between the shaft stop of the other hook rod and the arm for the chamber, and the shaft stop of the other hook rod and arm for the swing type paddy/brown rice separation device. In order to avoid any change in the angle of the hook rod relative to the handle, the swing type paddy/brown rice separator is designed so that only the angle of inclination can be changed without changing the swing angle, and the adjustment can be made easily. be. As can be seen from the solid lines and phantom lines in Fig. 10, the degree of inclination of the hook rod 30 with respect to the horizontal plane does not change even if the shaft 31 moves upward or downward; The angle between the swinging direction W arrow of the 11-pack stomach 18 of paddy brown rice and the horizontal line (swinging angle) hardly changes. The hook rod 16 is connected to the shaft '17.19 and the rotating shaft 2.
1 forms a three-point link, there is no change at all, and the hook rod 30 forms a parallel link with the hook rod 1G. Therefore, the swing type paddy/brown rice separator 18 always sorts grains at the same swing angle with respect to the horizontal plane, and the distribution of grains on the soil plate 54 can be adjusted by moving the shaft 31 up and down. Since the adjustment is made by changing only the degree of inclination of the paddy/brown rice separation device 18 with respect to the horizontal plane, the adjustment can be made extremely easily. In addition, the present invention allows the sorting action of the swing-type paddy/brown rice separation device to be adjusted simply by vertically adjusting the lower shaft stop of the diagonal member.
Since the separation device is completely constructed, its adjustment is extremely simple (therefore, it has the feature that it can be easily implemented even in a complicated configuration by integrally assembling the separation device above the selection chamber. In the present invention Since the hook rod supporting the separator is installed below the separator, the center of gravity of the rice hulling sorting device is lower than in the case where the hook rod supporting the separator is installed above the separator. This reduces the resistance to vibrations caused by the shaking of the separator, making it possible to stabilize the sorting action and accurately perform uniform sorting.There are no hook rods on one side of the sorting plate 1. Therefore, the top surface of the sorting plate becomes easy to see, and the sorting action can be controlled normally at all times.Furthermore, according to this defense, when changing the inclination angle of the swinging type paddy/brown rice separation device, the swinging type paddy/brown rice separation device on the elevator side (Since there is little vertical movement of the device, there is little change in the positional relationship between the discharge part of the brown rice paddy grain mixture of the elevator and the inflow part of the brown rice grain mixture of the swinging type paddy/brown rice separator, and the The mixture of brown rice and paddy grains is supplied to the rocking type paddy/brown rice separator in the - state, and the rocking type paddy/brown rice separator can perform accurate and stable brown rice grain separation work.
