Description

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

The present invention relates to a small-sized rice swamp sorting device in which a swing-type separating device for separating paddy and brown rice is integrally assembled above a hulling section.

When hulling with a huller, not all grains can be threshed at once, so some unhulled rice is discharged.

Therefore, the hulling device always requires a device for separating paddy and brown rice, and the separated paddy grains are recirculated and defloated. The present invention uses a high-performance rocking type paddy/brown rice separation plate in the separation device, and furthermore, the separation plate is mounted in a position above the hulling section to reduce the size of the whole, and in this way, the upper part is fixed. This special structure is designed to absorb the rocking reaction force that occurs when the body shape is changed.

To explain with an example diagram, 1 is a roughly rectangular parallelepiped-shaped rice grain sorting box that houses a hulling room 2, a grain sorting room 7, etc., and a supply hopper 4 is attached at an upper position on one side of the left and right sides when viewed from the front. The lower end of the hopper 4 is closed into the above-mentioned hulling chamber 2. Inside the hulling chamber 2, a pair of hulling rolls 5, 5 are shaft-mounted in parallel on the left and right sides. A lower drop opening 6 opens into the wind selection chamber 7.

Reference numeral 48 denotes a control valve mounted on a shaft at the entrance of the supply hopper 4, to which a wire 47 for automatic control, which will be described later, is connected.

The wind selection chamber 7 is provided horizontally in the left-right direction when viewed from the front, and starts from a suction port 8 provided on one side of the hulling wind speed chamber 1 on which the supply hopper 4 is attached, and advances almost horizontally as it is. It is connected to a suction row 4 of a suction prower 3 attached to the side of the pond. At a position close to the suction port 8, and below the lower drop port 6, there is provided a first object receiving trough 10, in which a first screw 9 is installed horizontally in the front-rear direction, and a suction blower is slightly inserted. A second receiving gutter 11 is provided at a position proceeding in the direction 3, and a second screw 1 is installed on the gutter 11 in the front and rear direction.
2 is installed horizontally. 13 is a case that becomes the wind cylinder of the wind selection room 7.

The elevator 33 that lifts the first grain (mixture of paddy and brown rice) discharged from the hulling-style sorting room 1 upwards is mounted at a special position with a special mounting bracket. That is, an L-shaped mounting bracket 34 is fixed with a bolt 36 at the lowest end position on either the left or right side when viewed from the front where the suction port 8 is formed in the rice-hulling wind selection chamber 1. When viewed from the front, the mounting bracket 34 is installed so as to be flush with the bottom surface of the rice hulling style selection chamber 1 and in contact with the floor surface 74, and when viewed from the upper position, as shown in FIG. The side wall 3 of the hulling wind speed chamber 1 is attached by a mounting portion 34' that is 1' longer than the horizontal center 1 at the front and rear of the selection chamber 1.
Furthermore, the mounting portion 34'' of the elevator 33 is bent in a direction to lengthen the left and right length of the hulling air velocity chamber 1, and the elevator 33 is fixed to the outside thereof with bolts 36.
Therefore, the elevator 33 is attached to the rice grain selection room 1 using the mounting bracket 34.
If it is fixed, the rice tank sorting chamber 1 will be formed substantially longer on the left and right sides by the length of the elevator 33. A stand 69 on which a heavy motor 70 is attached is integrally installed on the opposite side of the rice swamp wind selection room 1 to which the elevator 33 is attached, using the rice husk draft wind selection room 1. When viewed from the front, the stand 69 extends and protrudes flush with the bottom surface of the hulling wind speed chamber 1, and a motor 70 is mounted on it.
The motor 70 is fixed in the vicinity of the rice hulling wind selection chamber 1. Therefore, the rice-nara wind selection room 1 is configured to be able to move laterally on the floor together with the elevator 33 and the motor 70, and the interior of the substantial left and right sides is from the outer end of the elevator 33 to the platform 69. 1" to the outer edge. A swing type paddy/brown rice separation device 18 is installed at the upper part of the paddy tank wind selection room 1. That is, near the place where the supply hopper 4 of the hull removal wind selection room 1 is installed. is provided with a bearing 15 projecting upward, and the lower end of a diagonal village 16 is fixed to the upper end of the bearing 15 by a shaft 17.The upper end of the diagonal village 16 is located on the opposite side of the supply hopper 4, that is, the motor
0, and its upper end is pivoted to the lower part of the separating device 18 via a shaft 19. The lower end of the other oblique village 30 corresponding to the oblique punch 16 is fixed to a shaft 31 that moves up and down about a shaft 29, and the upper end of the oblique punch 30 is fixed to the lower surface of the separation device 18 by a shaft 32. be done.
A bearing 20 is provided at an intermediate position between the slanted village 16 and the slanted village 30, and a rotating shaft 21 is mounted on this bearing 20. An eccentric 23 is mounted on the rotating shaft 21, and its arm 24 is mounted on the rotating shaft 21. It is mounted on a shaft 19. 22 is the separation device 1
It is a balance weight that eliminates the reaction force of 8, and the rotation axis 2
Attached to 1.

The separation board 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 separation device 1
The swing type paddy/brown rice separation board 54 of 8 is preferably made of a rough surface made of a pressed metal plate, with day being the supply side, L being the discharge side, HI being the shaking up side, and LI being the shaking side. On the side L, there is a brown rice outlet 50 on the HI side on the upper side of the bridge, and LI on the lower side of the bridge.
An unhulled rice outlet 52 is provided at a position closer to the center, and a mixed rice outlet 51 is provided in the middle thereof (see FIG. 8). Stepped transfer troughs 55, 56, and 57 whose bottom surfaces are stepped feeding surfaces are integrally attached to each outlet, and adjustment plates 61 and 63 are provided at the boundaries of each outlet, respectively. provided. The adjustment plate 61 is adjustable in the direction of the arrow in FIG. 8, and as shown in FIG. 7 and FIG. A smooth rare plate 62 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 flow plate 62 will be located above the right end of the stepped movable gutter 57, but at this time, the flow will flow to the right side from the adjustment plate 61. All of the grains flowed into the stepped transfer gutter 56 below, and even if the adjustment plate 61 was extremely shifted to the right in the figure as shown in FIG. The grains are all fed up to the step-like transfer trough 57 by the action of the step-like auxiliary transfer plate 57'. In Fig. 8, 58 is a brown rice discharge gutter, 59 is a mixed rice discharge gutter, 6 is a raw rice discharge gutter,
72 is a rubber cover put on for safety. The oscillating type paddy/brown rice separation plate 54 having the rough surface is used to perform the required number of stages of paddy/brown rice separation as shown in FIG. That is,
Receiving frames 64, 64 standing upright on both sides are attached, and a swing type paddy/brown rice separating board 54 is stacked between the receiving frames 64, 64 so as to have a desired number of stages, and is fixed by tightening bolts 66 from the left and right sides. The reason why the oscillating paddy/brown rice separator 54 is polymerized one after another in this way is to match the threshing efficiency with the rubber rolls. 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 structure is such that the number of swing-type paddy/brown rice separation plates 54 can be easily increased or decreased with little effort. Reference numeral 49 in FIG. 3 is a distribution device for distributing grains to the vertically stacked oscillating paddy/brown rice separation plates 54 of each stage. The lower end of the elevator 33 is fixed to the side of the rice tank sorting chamber 1 by a mounting bracket 34, and the middle part is tightened by a tying bracket 37 using the supply hopper 4. The structure shown in Figure 5 is
A connecting piece 38 is fixed to a corner of the supply hopper 4, and one end is fixed to the connecting piece 38 with a screw 401, and the other end is vertically attached with a screw 42. 39 and 41 are new parts provided for screwing.

In this way, the lower part of the elevator 33 is attached to the mounting bracket 34.
The upper portions are each fixed to the hulling air speed chamber 1 by a fastening metal fitting 37. An adjustment hopper 43 is suspended from the upper part of the elevator 33 via links 44 and 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 adjusting hopper 49 is provided with a protruding piece 46, one end of which is connected to the protruding piece 46, and the other end of a wire 47 is connected to the adjusting valve 48. In the figure, 53 is an outlet, 65 is an independent plate, 71 is a mixed rice receiving gutter, and 73 is an overflow gutter.

Next, we will discuss the effect.

When the raw material paddy is put into the supply hopper 4, the paddy is hulled by the hulling rolls 5, 5, and sent to the wind selection chamber 7 through the drop port 6.
flow down inside.

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 3 through the suction port 14, and are removed from the system. On the other hand, brown rice and unhulled paddy grains, which are heavy in weight, are directly deposited on the first receiving trough 10, are transported in the front and back direction by the first screw 9, flow into the lower part of the elevator 33, and are transported to the bottom of the elevator 33. After rising in the adjusting hopper 33, the adjusting hopper 43 is raised by the elasticity of the spring and lowered by the weight of the grain, so that it descends according to the amount of grain stored in the adjusting hopper 43. The links 44, 45 guide the vertical movement of the adjustment hopper 43. When the adjustment hopper 43 moves downward, the other end of the protruding piece 46 moves up, so the wire 47 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 regulating valve 48 that is closed. 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. Since the upper end of the diagonal village 16 is attached to the right side at approximately 45° in FIG.
The movement of 9 (same for the shaft 32) is a reciprocating movement diagonally up and down when viewed from the front as indicated by the W arrow. Therefore, HI is on the bridge upper side and LI is on the swinging side.

Therefore, the board surface 54 is composed of a rough surface,
Since it is a reciprocating motion on the bridge in the W direction, looking at the flow of grain on the board surface 54, as shown in Figure 8, brown rice with a high specific gravity flows BI along the direction HI, and grains with a low specific gravity flow BI. The rice grains flow E3 along the underbridge side LI, and in the middle, the mixed grains that are not separated flow E2, and each outlet 50
, 51, 52. Each outlet 50, 51, 52 of this separation device 18 has stepped transfer troughs 55, 56, 57.
are attached to each of them, the brown rice is gradually transferred through the stepped transfer gutter 57, and is taken out of the system through the brown rice discharge gutter 58 attached at the end, and the paddy grains flow like the E3 line and then are transferred to the stepped transfer gutter 57. The mixed grains are transferred by the transfer gutter 55, returned to the supply hopper 4 by the paddy rice removal gutter 60, and mixed into the raw material again, and the mixed grains flow like the E2 line.
The mixed rice is transferred by the stepped transfer gutter 56, flows into the mixed rice receiving gutter 71 from the mixed rice take-out gutter 59, and flows into the first rice receiving gutter 10 from the lower communication port, where it is subjected to a re-sorting action. On the other hand, due to its performance characteristics, the separator 18 may not match the amount of paddy swamp produced by the hulling rolls 5, 5, but in such a case, a swinging type paddy/brown rice separating plate consisting of an independent plate 65 is used. 5
Adjust by increasing or decreasing 4. 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 considerably reduced by the balance weight 22. The present invention has the above-mentioned structure and function, and in particular, the swinging direction of the swinging type paddy/brown rice separating device 18 and the structure of the hulling section are novel.

That is, unless the swing type paddy/brown rice separation device 18 is of a multi-stage type as shown in FIG.
Separation of the mixed whole grains hulled by step 5 cannot be achieved. Therefore, on the swing type paddy/brown rice separation plate 54 of each stage,
Depending on the case, grains of about 50k9 to 100k9 are distributed and are violently rocked by the eccentric 23 or crank arm, so the reaction force generated each time the reciprocating rocking in the W direction is quite large. The rice grain selection room 1 having a normal structure is insufficient as a foundation, and it becomes necessary to have a structure that is more robust than necessary. However, in the present invention, as described above and shown in the drawings, the motor 70 is fixedly provided in the vicinity of the rice marsh wind selection chamber 1,
The swinging type paddy/brown rice separation board 13 is mounted above the paddy marsh-style sorting room so that it can swing freely in the W direction so that the swinging direction is the direction connecting the motor 70 and the hulling room 2. Since the size can absorb the rocking reaction force, there is no need to make the structure of the base part more robust than necessary, and therefore, the effect can be provided within the range that the general public can purchase.
