Description

[Detailed description of the invention] The present invention relates to a rice hulling sorting device.

A rice hulling device is always equipped with a device to separate paddy and brown rice.

This separator is a swing-type paddy/brown rice separator, and the mangoku is simply a wire mesh. be done.

Mangoku is simply a wire mesh, so it is extremely light in weight and usually
It is integrated into the rice hulling section.

The oscillating type paddy/brown rice separator is several steps superior in performance to Mangoku, but because of its structure in which the metal plate is oscillated, it is extremely heavy and difficult to assemble integrally with the huller. Therefore, they are usually installed side by side on the floor.

Japanese Patent Laid-Open Publication No. 1973-1997 discloses a hulling sorting device in which a swing-type paddy/brown rice separator is swingably mounted above the hulling chamber, and an elevator is attached to the side of the hulling chamber to reach the separating device. 91846
In this device, the separating device is attached to the suction cover above the separating device with its upper end fixed to the lower end of the diagonal rod, and the upper end of the diagonal rod is fixed to the lower end of the diagonal rod. The supported suction cover can be moved up and down.

For this reason, a member is required to support the separation device above the separation device, and the height of the hulling and sorting device increases by 1, and the center of gravity is located above, which reduces the vibration stability of the hulling and sorting device. As it worsens, 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 diagonal rod also changes, and the swing angle changes at the same time as the inclination angle, making it difficult to adjust. This has the disadvantage that it is difficult to operate.

Furthermore, there is a device known as Utility Model Publication No. 38-15060i that moves the support plate of the swinging sorter up and down via the machine frame by moving the machine frame support rod of the swinging sorter up and down. Not only does this require a large amount of force to move the entire heavy machine frame up and down, but the inclination of the movable support plate relative to the horizontal plane changes as the inclination of the machine frame changes.
Since the swinging angle of the swinging sorting board is subject to change, there is a drawback that it is difficult to adjust its inclination.

The present invention eliminates the above-mentioned drawbacks, and by providing a separating device support member below the separating device, the center of gravity of the hulling and sorting device is lowered to improve stability against vibrations, and the sorting action can be performed stably and accurately. At the same time, the top surface of the 5 sorting plate is made easy to see so that the sorting action can be controlled at all times, and the rice hulling wind sorting chamber, which is the machine frame, is pivoted to a fixed dimension with respect to this rice graining wind sorting chamber. It is possible to change the inclination of the swing type paddy/brown rice separation device with respect to the hulling style sorting chamber with a small force by raising and lowering the diagonal rod that is pivoted to this. A three-point link formed by the shaft stop point of the other diagonal rod, the shaft stop point of the arm, and the shaft stop point of the other diagonal rod and the arm for the swing type paddy/brown rice separation device is used to connect the paddy sieve to the wind sorting chamber. A rice huller that does not cause any change in the angle of the diagonal rod so that the swinging type paddy/brown rice separator can change only the tilt angle without changing the swing angle, making it easy to adjust. The purpose of this invention is to provide a sorting device.

The elevator 33 that lifts the first grain (mixture of paddy and brown rice) discharged from the above-mentioned hulling-style sorting room 1 upwards is mounted at a special position with a special mounting bracket.

That is, at the lowest end position on either the left or right side when viewed from the frontal force that formed the suction port 8 of the rice-hulling wind selection chamber 1, there is an L

Therefore, the mounting bracket 34 is used to attach the elevator 33 to the rice-hulling wind selection chamber 1.
If it is fixed, the rice hulling wind selection chamber 1 will be formed substantially longer on the left and right sides by the length of the elevator 33.

On the opposite side of the rice hulling wind selection chamber 1 to which the elevator 33 is attached, a stand 69 on which a heavy motor γ0 is mounted is integrally installed using the rice hulling wind selection room 1.

When viewed from the front, the rigging 69 extends and protrudes flush with the bottom surface of the rice grain selection chamber 1, and the motor 10 is placed on it.

Therefore, the rice hulling wind selection room 1 has an elevator 33 and a motor TO

A swing-type paddy/brown rice separation device 18 is attached to the upper part of the rice hulling-style sorting chamber 1.

That is, a bearing 15 that protrudes upward is provided near the location where the supply hopper 4 of the rice grain selection room 1 is installed, and the lower end of the diagonal rod 16 is fixed to the upper end of the bearing 15 by the shaft 11. .

The upper end of the diagonal rod 16 is located on the opposite side of the supply hopper 4.

The lower end of the other diagonal rod 30 corresponding to the diagonal rod 16 is connected to the shaft 2.
A shaft 31 that moves up and down with respect to the rice grain selection chamber 1 about 9.
The upper end of the diagonal rod 30 is pivotally fixed to the lower surface of the separation device 18 by a shaft 32.

Many configurations are possible, but in the configuration shown in FIG. 3, the bearing 2γ is fixed near the bearing 15, and the bearing 2γ is
1 is equipped with a threaded rod 67, a piece 68 is screwed onto the threaded rod 67, a shaft 31' is provided above the rod 31', and a vertical movement adjustment rod 28 is installed between the piece 68 attached to the shaft 31'. A bearing 25 is installed at a position slightly apart from the bearing 2T, and the shaft 3
The vertically movable rod 26 is mounted between the screw rod 67 and the shaft 31', and the shaft 29 is used to connect the vertically movable rod 26 to the bearing 25.
When rotated, the movable rod 26 alternately moves up and down like a seesaw around the shaft 29□.

Although FIG. 10 shows an embodiment different 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, one end of the vertically movable rod 26 is directly attached to a shaft 1T to which the diagonal rod 16 is attached, and the aforementioned shaft 31 is mounted on the other side of the movable rod 26. The lower end of the diagonal rod 30 is mounted on a shaft, and pieces 68 and 68 are mounted on the shaft 31 at a distance as shown in FIG. Tops 68 and 68 are respectively screwed onto the rod 6γ, and a vertical adjustment rod 28 is attached between the top and bottom pieces 68 and 68.

A bearing 20 is provided at an intermediate position between the diagonal rod 16 and the diagonal rod 30, a rotating shaft 21 is mounted on the bearing 20, and an eccentric 23 is mounted on the rotating shaft 21, and the arm 2
4 is mounted on the shaft 19.

22 is a balance weight that eliminates the reaction force of the separating device 1B, and is attached to the rotating shaft 21.

Although the arm 24 in FIG. 10 is not provided with an eccentric, since the rotating shaft 21 in this figure is a crank, the eccentric 23 is not required.

That is, arm 24 has eccentric 2 at one end.
3 or an eccentric device such as a crank, which connects the hulling-type rice selection chamber 1 and the swinging type hulling-type brown rice separation device 18.

The separation device 18 is provided in multiple stages as shown in FIG.

That is, the receivers 64 are provided on the left and right sides, and are used to make the number of stages variable.

The plate surface 54 of the separation device 18 is preferably made of a rough and rough surface obtained by pressing a metal plate, and H is the supply side, L is the discharge side, Hl is the swinging side, Ll is the swinging side, and the discharge side is In addition, a brown rice outlet 50 is provided near the shaking upper side H1, an unhulled rice outlet 52 is provided near the shaking lower side L1, and a mixed rice outlet 51 is provided in the middle (see Fig. 8). )
.

Each outlet is integrally provided with stepped transfer troughs 55, 56, and 57 whose bottom surfaces are stepped upper surfaces, and adjustment plates 6L63 are provided at each boundary of each outlet. .

The adjustment plate 61 is adjustable in the direction of the arrow in FIG. 8, and as shown in FIG. 1 and FIG. An original plate 62 with a smooth surface is integrally attached.

When the adjustment plate 61 moves to the left side in the figure as shown in FIG. 6, the right end of the original plate 62 will be located above the right end of the step-like transfer gutter 5γ, but at this time, the amount of water flowing out to the right side from the adjustment plate 61 All of the grains flow into the stepped transfer gutter 56 below, and even if the adjustment plate 61 is extremely shifted to the right side in the figure as shown in FIG. are all fed to the stepped transfer gutter 5T by the action of the stepped auxiliary transfer plate 51'.

In FIG. 8, 58 is a brown rice discharge gutter, 59 is a mixed rice discharge gutter, 6-0 is a paddy rice discharge gutter, and γ2 is a rubber cover put on for safety.

The board surface 54 made of the rough surface is formed by overlapping the required number of stages as shown in FIG.

That is, upright receiving frames 64 and 64 are attached to both sides, and the board surfaces 54 are overlapped so that a desired number of stages is formed between the receiving frames 64 and 64, and the board is fixed by tightening bolts 66 from the left and right sides.

The reason why the board surfaces 54 are polymerized one after another in this way is to match the deweighing efficiency with the rubber roll.

That is, the efficiency of the hulling by the rubber rolls 5, 5 and the efficiency of the separation by the separating device 18 must be made to completely match each other in order to achieve sufficient operation and effect. , the number of board surfaces 54 can be easily increased or decreased with little effort.

49 in FIG. 3 indicates the board surface 5 of each layer stacked vertically.
This is a distribution device that distributes grain to 4.

The lower end of the elevator 33 is fixed to the side of the rice hulling and wind-selection chamber 1 with a mounting fitting 34, and the middle portion thereof is tightened with a tightening fitting 37 using the supply hopper 4.

In the structure clearly shown in FIG. 5, a connecting piece 38 is fixed to a corner of the supply hopper 4, one end of which is fixed to the connecting piece 38 with a screw 40, and the other end is tightened with a screw 42.

39 and 41 are bent portions provided for screwing.

In this way, the elevator 33 is fixed to the rice hulling wind selection chamber 1 at the lower part by the mounting fitting 34 and at the upper part by the tightening fitting 37.

At the top of the elevator 33, an adjustment hopper 43 is connected to a link 44.
．． 45 so as to be vertically movable.

The adjustment hopper 43 has a built-in spring mechanism so as to move up and down according to the storage amount, 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, and one end of the wire 41 is connected to the protrusion 46, and the other end of the wire 41 is connected to the adjustment valve 48.

L In the figure, 53 is an outlet, 65 is an independent plate, 71 is a mixed rice receiving gutter, and γ3 is an overflow gutter.

Next, we will discuss the effect.

When paddy raw material is put into the supply hopper 4, the paddy is hulled by the hulling rolls 5, 5, and then sent to the wind selection chamber T from the drop port 6.
flow down inside.

Since suction air from the suction blower 3 is blown across the wind selection chamber T, light rice husks are suctioned, enter the suction blower 3 through the suction port 14, and are removed from the system.

On the other hand, the heavier brown rice and the unhulled paddy grains are directly transferred onto the pick-and-pickle receiving trough 10, are transported in the front-rear direction by the first screw 9, and flow into the lower part of the elevator 33. After rising in the elevator 33, it is stored in the adjustment hopper 43.

Since the adjustment hopper 43 is configured to rise due to the elasticity of the spring and descend depending on the weight of the grain, the adjustment hopper 43 descends according to the amount of grain stored in the adjustment hopper 43.

Links 44, 45 guide the vertical movement of the adjusting hopper 43.

When the adjustment hopper 43 moves downward, the other end of the protruding piece 46 moves upward, so the wire 41 whose one end is fixed to the protruding piece 46 is pulled up and attached to the other end of the wire 47. It acts to close the control valve 48 that is present.

That is, when the amount stored in the adjustment hopper 43 becomes larger than the scheduled amount, the amount will no longer flow from the supply hopper 4.

The grain in the regulating hopper 43 is arranged so that a constant amount of grain flows continuously into the distribution device 49.

Therefore, a certain amount of the mixture of brown rice grains constantly flows into the distribution device 49, and after being distributed,
5 onto the board surface 54.

Reference numeral 18 indicates the entire swing type paddy/brown rice separator, and the mixed grains flowing in from the inlet 53 are subjected to a sorting action in the direction of the arrow W.

That is, when the rotating shaft 21 rotates, the eccentric 23 rotates, causing the shaft 19 to reciprocate in the left-right direction at the upper end of the arm 24, but the upper end of the diagonal rod 16 is moved to the right by about 45 degrees in FIG. Because it is installed tilted,
The movement of the shaft 19 (the same applies to the shaft 32) is a reciprocating movement diagonally up and down, as shown by the W arrow, when viewed from the front.

Therefore, Hl is on the swinging up side and Ll is on the swinging down side.

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 rice grains flow E3 along the swinging side L1, and the mixed grains that are not separated flow E2 in the middle, and each outlet 5
0.5L52.

Since step-like transfer gutter 55,56゜57 is attached to each outlet 50.5L52 of this separation device 18, the brown rice is gradually transferred by the step-like transfer gutter 57, and the brown rice attached at the end is The paddy grains are taken out of the thread from the discharge gutter 58, flow like the E3 line, are transferred by the stepped transfer gutter 55, are returned to the supply hopper 4 by the paddy rice removal gutter 60, and are mixed into the raw material again, forming mixed grains. is E2
After flowing like a line, it is transferred by the stepped transfer gutter 56, flows into the mixed rice receiving gutter γ1 from the mixed rice take-out gutter 59, flows into the first rice receiving gutter 10 from the lower communication port, and is recycled. Subject to sorting action.

On the other hand, due to its performance characteristics, the separation device 18 may not match the amount of hulling by the hulling rolls 5, 5.
In such a case, the board surface 54 consisting of the independent board 65 is adjusted by increasing or decreasing the number.

The separating device 18 is of a multi-stage type as in the embodiment, and since it is violently reciprocated in the W direction, a considerable reaction is generated. Since the balance weight 22 is attached, the reaction force is significantly reduced by the balance weight 22.

Therefore, the distribution of grains on the board surface 54 of the separating device 18 is made to be uniform over the entire surface.

For this purpose, it is necessary to make the swinging lower side L1 considerably lower than the swinging upper side H1, and there is a weight to adjust the height of this swinging side L1.

This adjustment can be done using the screw rod 67 shown in FIG.
This is done by adjusting the screw rod 6γ shown in the figure.

That is, when the screw rod 6γ is rotated in FIG. 3,
The shaft 31' moves in the vertical direction, so the vertically movable rod 26 moves like a seesaw around the shaft 297.
Since the shaft 31 on the reaction side moves up and down, the swinging side L1 moves up and down, and the lateral inclination when viewed from the front is adjusted.

In the case of the embodiment shown in FIG. 10, the horizontal inclination is adjusted by directly moving the shaft 31 up and down, and when the threaded rod 6γ is rotated, the lower pieces 68 and 68 move closer to each other, twist or move apart. Therefore, the upper shaft 31 rotates in the vertical direction, thereby adjusting the degree of inclination of the board surface 54.

The present invention is constructed as described above, and in particular, the rice hulling wind sorting chamber serving as the machine frame is a fixed IT, and the shaft is moved up and down with respect to the rice hulling wind selection chamber, and the shaft is fixed to this. By moving the diagonal rod up and down, the inclination of the swing type paddy/brown rice separation device relative to the hulling wind sorting chamber can be changed with a small force. The three-point link formed by the shaft stopping point of the arm, the other diagonal rod for the swing type paddy/brown rice separation device, and the shaft stopping point of the arm does not cause any change in the angle of the diagonal rod with respect to the rice hulling style selection chamber. In this way, the swing type paddy/brown rice separator can change only its tilt angle without changing its swing angle, and its adjustment can be facilitated.

In other words, as shown by the solid line and the temporary line in Fig. 10, the diagonal rod 3
The degree of inclination of 0 with respect to the horizontal plane does not change even if the shaft 31 moves upward or downward. (oscillation angle) hardly changes.

The oblique rod 16 is connected to the shafts 1γ, 19 and the rotating shaft 2.
1 to form a three-point link, the diagonal rod 30 and the diagonal rod 16 form a parallel link without changing at all.

Therefore, the swinging type paddy/brown rice separator 18 always sorts grains at the same swinging angle with respect to the horizontal plane, and the distribution of grains on the board surface 54 can be adjusted by vertically moving the shaft 31. Since adjustment is made by changing only the degree of inclination of 18 with respect to the horizontal plane, adjustment can be made extremely easily.

In addition, the device of the present invention is configured such that the sorting action of the swing type paddy/brown rice separator is adjusted by simply adjusting the lower shaft stop of the diagonal rod up and down, so the adjustment is extremely simple. The separator is integrally assembled above the wind selection chamber, so that even a complicated configuration can be easily implemented.

In particular, in the present invention, since the diagonal rod supporting the separator is provided below the separator, compared to the case where the diagonal rod supporting the separator is provided above the separator, the rice hulling sorting device is The center of gravity of the separator is lower, and it is more stable against vibrations caused by the swinging of the separator. Therefore, the sorting action is stable, uniform sorting can be performed accurately, and there are no diagonal rods above the sorting plate. Therefore, the top surface of the sorting plate becomes easy to see, and the sorting action can always be controlled normally.
