[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large hulling device.

[0002]

2. Description of the Related Art Although the publicly known Japanese Patent Laid-Open No. 4-290557 does not describe the width of the hulling roll, a person skilled in the art would appreciate a large roll of 6 to 10 inches. It turns out that it is a huller. The large-sized hulling device is equipped with a wind elevator, a bucket elevator for finishing, a bucket elevator for finishing rice, and a bucket elevator for returning, by assembling a wind sorting unit and a hull head on a swing sorting unit.

[0003]

SUMMARY OF THE INVENTION According to the above-mentioned publicly known publication, a wind selecting section and a hulling head are provided on an oscillating selecting section for oscillating a selecting plate to separate mixed rice into paddy rice and brown rice. Since they are arranged side by side, since the position of the hulling head itself is high, there is a problem that the height of the squeeze bucket elevator in which the raw material is placed therein becomes abnormally high. However, when the swing selecting section, the wind selecting section and the hull head are arranged side by side,
Even the large-sized hulling apparatus as described above can be made into a compact and compact structure.

[0004]

Adhere to surface 38.

[0015]

[Operation] Next, the operation will be described. (Rice-rice action) Rice-rice fed to the supply hopper 10 manually or by the elevator is adjusted by the feeding roll 12 and the supply amount adjusting valve 13 by opening the opening / closing shutter, and the fixed rubber roll 14 and the moving rubber roll 15 are adjusted by a predetermined amount.
The rice husk is sucked and removed by the suction blower 22 while the rice husk is supplied and hulled and flowed downward from the falling board 17, and the mixed rice of paddy rice and brown rice falls into the first gutter 18 and the paddy rice. The second one, such as, falls into the second gutter 20. The mixed rice dropped into the first receiving trough 18 is conveyed from the right to the left by the first spiral conveyor 19 and flows into the supply bucket elevator 23, which is raised and distributed from the discharging trough 29 facing backward. The supplied rice drops into the gutter 28, is evenly distributed to the sorting plates 25 of the respective stages, and is sorted and separated. The finished rice of brown rice flows into the receiving gutter 32 of the finished rice bucket elevator 31 and rises, Will be taken over.

The unmixed mixed rice of unpolished rice and brown rice is returned from the mixed rice outlet 33 to the first receiving trough 18 and is circulated and reprocessed. The separated paddy rice flows into the return bucket elevator 35 from the paddy rice outlet 34, is returned to the head supply hopper 10, and is reprocessed.

(The present invention has a unique action) The frame 1 of the present invention is such that the hull-winding selection frame 6 and the rocking selection frame 7 are passed through the front and rear, and long longitudinal steel members 2 and 2 which cannot be separated from each other are joined together. Since it is formed by the left and right steel materials 3 and 3, the hulling / wind selecting frame 6 and the swing selecting frame 7 cannot be separated from each other, and it is difficult to transport, but the strength is enough for that, and 6 inches. A basic frame that can withstand a large 10-inch hulling device.

Further, since the length 4 of the left-right steel material 3 forming the frame 1 is formed to be substantially the same with reference to the lateral width of the wind selecting portion 5, the wind selecting portion 5 is used as the hull wind selecting frame 6. Not only is it assembled as it is, but since the swinging portion 37 has the same width as the wind selecting portion 5, belting, transmission cover and the like are easy.

Since the hulling head 9 is assembled on the upper part of the wind selecting part 5, the wind selecting part 5 is directly assembled on the hulling / wind selecting frame 6 placed directly on the floor surface 38. Since it is low in height, it can be directly supplied by hand even if it is large.

However, the most spiral conveyor 19 has a structure of transferring from the right to the left, and the tip thereof flows into the supply bucket elevator 23 in which the axial direction of the roller 42 for rotating the bucket belt is the left-right direction. It can be easily discharged rearward from the discharge gutter 29 at the upper part of the supply bucket elevator 23, and can be easily supplied to the rear sorting plate 25.

A finishing rice bucket elevator 31 is provided on the right outside of the swing selection frame 7 and a return bucket elevator 35 is provided on the rear of the hull wind selection frame 6.
Since there are three bucket elevators 23 and 3
1, 35 are evenly arranged around the frame 1, lower parts of the bucket elevators 23, 31, 35 are coupled to and supported by the frame 1, and upper parts thereof are the wind selecting part 5, the hull head 9 or the sorting plate 25. , And the lower end is adhered to the floor surface 38, so that the overall strength is improved.

[0022]

Uneven projections 24 are formed, and they are superposed in a large number of stages to form the paddy head 9 and A quadrangular sorting plate 25 having the same height is provided, and an outlet 30 of the finished rice sorted by the sorting plate 25 is provided on the rear side below the swing sorting unit 8 below the swing sorting unit 8. An outlet 33 for mixed rice and an outlet 34 for hulled rice, which are sorted by the sorting plate 25, are formed on the front side, and are hulled by the hulling head 9 on the left outer side of the hulling wind selection frame 6. The feed bucket elevator 23 that supplies the mixed rice that has been wind-selected by the wind selection unit 5 to the selection plate 25 of the swing selection unit 8 has its lower end with the floor surface 3 with its axis centered in the left-right direction.
8, a return bucket elevator 35 is provided on the right outside of the hulling / winding selection frame 6 to fried the hulled rice from the hulled rice outlet 34 and returning it to the supply hopper 10 of the hulling head 9. The floor is 38
Installed on the right side of the rear part of the swing selection frame 7 is a finished rice bucket elevator 31 for graining the finished rice from the finished rice outlet 30 with its axial center in the front-rear direction and the lower end being the floor surface. Since the bucket elevators 23, 31, and 35 are installed in a state of being installed on a large-sized hulling device that is fixed to the frame 1 side, the frame 1 includes the hulling wind selection frame 6 and the swing selection frame 7 in the front and rear direction. Long longitudinal steel material 2, which cannot be separated by passing through
Since it is formed of 2 and the left and right steel materials 3 and 3 that connect the two, the basic frame has sufficient strength and can withstand even a large hulling device. The length 4 of the left-right steel material 3 forming the frame 1 is
Since the width of the wind selecting portion 5 is formed substantially the same as the reference, the wind selecting portion 5 can be easily assembled, and the swinging portion 37 and the wind selecting portion 5 can be easily assembled.
Since it has the same width as, it is easy to hang the belt and cover the transmission. Since the hulling head 9 is attached to the upper part of the wind selecting part 5 provided in the hulling wind selecting frame 6 placed directly on the floor surface 38, the height is low, and even if it is large, it is manually operated. Can be supplied directly. The most spiral conveyor 19 has a structure for transferring from the right to the left, and the supply bucket elevator 23 is provided with rollers 42.
Since the axial direction of is in the left-right direction, it can be easily discharged rearward from the discharge gutter 29 in the upper part of the supply bucket elevator 23, and can be easily supplied to the rear sorting plate 25. Since the finishing rice bucket elevator 31 is provided on the right outer side behind the swing selection frame 7, and the return bucket elevator 35 is provided on the rear outer side on the right side of the chaff selection frame 6,
The three bucket elevators 23, 31, and 35 are evenly arranged around the frame 1, the lower portions of the bucket elevators 23, 31, and 35 are coupled to and supported by the frame 1, and the upper portions of the bucket elevators 23, 31, and 35 are connected to the wind selecting unit 5 or the paddy field. The lower end is bonded to the sliding head 9 or the cover of the selection plate 25 and the lower end is bonded to the floor surface 38, so that the overall strength is improved.
