Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a grain stirring device.

(Prior Art) To explain the prior art to which this application applies, in FIG. A dividing plate F is a partition plate that supplies grains from the grain supply port A to the inlet C of the swinging distribution plate B, swinging the swinging distribution plate B, and leveling the grains. When the surface layer is leveled at E, the grains, which have become uniform in the width direction, are partitioned by a partition plate F when flowing out from the outlet D, and are divided into, for example, approximately exactly three equal parts.

Therefore, for example, it is possible to uniformly supply the material to a multistage sorting plate.

(Problems to be Solved by the Invention) The above-mentioned known example is a method in which grains supplied from a supply port A are collected in a swing type distribution plate B, leveled by a leveling plate E, and distributed and discharged from an outlet part D. However, with this method, there is a problem that the grain supplied from the supply port A is not horizontally dispersed, so the width is insufficient, and the large number of partition plates F cannot be provided.

(Object of the Invention) The present invention enables grains supplied to the distribution gutter to be dispersed laterally, thereby increasing the width of the distribution gutter and allowing a large number of partition plates to be provided.

(Means for Solving the Problems) Accordingly, the present invention makes the base of the dust pan-shaped outlet portion 28 whose width increases as it approaches the tip end appear at a position lower than the terminal end of the horizontal cylindrical inlet portion 43, and the inlet portion 43 and the base of the outlet section 28, there are provided an abutting wall 46 against which grains flowing into the inlet section 43 collide and reflect, and a reflecting wall 47 that discharges the reflected grains from the abutting wall 46 to the outlet section 28.

Furthermore, although both the abutting wall 46 and the reflecting wall 47 are not shown, they may be inclined walls. Further, a diverging guide wall may be installed on the plate surface of the outlet portion 28.

The sorting plate 31 has a structure in which multiple stages are stacked together, and, like the guide rolls 2, 3, shafts 15, 16, rotating shaft 24, etc., a swing support rod 33 is attached to a shaft 32 provided in the front-rear direction.

A brown rice channel 38 is provided outside the brown rice outlet 35, and the brown rice channel 38 is connected to an elevator 39. 4
0 is a storage tank.

(effect) Next, we will discuss the effect.

Referring to FIG. 4, to first describe the general operation, unhulled rice a supplied to the elevator 1 rises and is supplied to the hulling section 9, where it is divided into unhulled rice a, brown rice b, and unhulled grains. c, and these are fed into the wind sorting section 21 on the side, where the paddy c is wind sorted, and only the unhulled rice a and the brown rice b flow into the swinging sorting section 41 and are sorted. A is returned to elevator 1, and brown rice b is excluded from the system.

Describing the specific effects using Figure 5,
When raw material a is supplied to the loading port 5, the elevator 1
The liquid is lifted up by the bucket belt 4 and stored in the fixed hopper 8 through the discharge port 7. When the stored amount exceeds, it flows out from the overflow hole 11 and is returned to the filling port 5. By opening the on-off valve 12, the grain stored in the fixed hopper 8 is fed out by the feeding roll 17, and flows on the sloping span plate 18 to the huller, which is diagonally above and below the lower end of the hopper. Supplied between rolls 13 and 14,
The rice is hulled and flows into the widthwise uniform diffuser 22. The rotating shaft 24 of the suction blower 23 is rotated, and the eccentric ring 25 is fitted onto the rotating shaft 24. Therefore, when the rotating shaft 24 rotates, the eccentric ring 25 rotates, and the eccentric ring 25 rotates. The rod 26, whose upper end is fixed, vibrates obliquely up and down, and therefore the widthwise uniform diffuser 22, which is fixed at the lower end of the rod 26, vibrates obliquely up and down. Meanwhile, leaf spring 2
7 elastically supports the widthwise uniform diffuser 22.

Therefore, the hulled material that has been hulled between the hulling rolls 13 and 14 flows into the entrance portion 43 of the swinging widthwise uniform diffuser 22, continues as it is, and reaches the end of the downward bending path 44. It collides with the wall 46, is reflected, collides with the reflective wall 47, is further reflected, and is emitted in the direction of the exit section 28. At this time, because it is reflected twice and has momentum, and because the widthwise uniform diffuser wall 22 is oscillated by the eccentric wheel 25, the hulled grains are dispersed in the width direction, and the grains are dispersed at the outlet. 28, it is emitted in a substantially evenly distributed manner.

Thus, the air sucked by the blower 19 passes through the fast air path 20, passes below the widthwise uniform diffuser 22, passes through the grains of rice grains falling from the lower end opening 28, and enters the wind selection section 21. When ascending, the light rice grain c is blown away and sorted, and the rice grain c
is sucked by the suction blower 23 and removed from the system. The hulled grains uniformly falling from the outlet 28 are supplied onto a distribution plate 29. The distribution plate 29 is a sorting plate 31
Since the sorting plate 31 is attached so as to be swingable in the left and right directions by the swinging support 33, the distribution plate 29 also moves left and right together with the sorting plate 31, so that the bottom wall It is fed by the feeding protrusion 30 and moves to the end, and at that time, it is further distributed and partitioned in the width direction, and distributed and supplied to the sorting plates 31 of each stage. Paddy rice a and brown rice b supplied onto the sorting plate 31 are sorted by the action of the sorting protrusion 34, and brown rice b is taken out from the brown rice outlet 35 into the brown rice flow path 38, supplied to the finished rice elevator 39, and raised.
The finished rice is stored in a storage tank 40. The separated unhulled rice a is supplied to the mangoku 42 from the unhulled rice outlet 36, straw waste etc. are removed, and only unhulled rice a flows into the unhulled rice return opening 37, where it joins with unhulled rice a from the loading opening 5 and is recycled. It is processed.

(Effects) In the known example, the grains supplied from the supply port A are stored in the swinging distribution plate B, leveled by the leveling plate E, and distributed and discharged from the outlet D. However, there is a problem in that the grain supplied from the supply port A is not horizontally dispersed, so the width is insufficient, and the large number of partition plates F cannot be provided.

However, in the present invention, the base of the dust pan-shaped outlet part 28 whose width becomes wider as it reaches the tip is exposed at a position below the terminal end of the horizontal cylindrical inlet part 43, and the terminal end of the inlet part 43 and the base of the outlet part 28 are and an abutting wall 46 on which the grains flowing into the inlet portion 43 collide and reflect.
Since the grain agitation device is provided with a vertical flow path 45 having a reflecting wall 47 which discharges the grain reflected by the abutting wall 46 to the outlet part 28, the grain flowing into the inlet part 43 is After being reflected on the abutting wall 46, it is reflected again on the reflecting wall 47 and is discharged to the dust pan-shaped outlet section 28 whose width increases as it reaches the tip, so that the grain is sufficiently agitated, and the number of partition plates 48 is increased. can.
