因此，期望一種裝置，能夠使稻穀以在葉輪部的旋轉軸心方向上盡可能均勻分佈的狀態與脫殼部碰撞，並且有效率地進行作業。 Therefore, there is a demand for an apparatus that can make rice collide with the shelling portion in a state of being distributed as uniformly as possible in the direction of the rotation axis of the impeller portion, and operate efficiently.

本發明的稻穀脫殼裝置的特徵構成在於，具備：稻穀供給部，係將從外部運入的稻穀向徑向外方排出；葉輪部，係沿著前述稻穀供給部的外周設置以接收從前述稻穀供給部排出的稻穀，並且繞著位於前述稻穀供給部之中心的旋轉軸心旋轉，將從前述稻穀供給部排出的稻穀向徑向外方引導；以及脫殼部，係接收由前述葉輪部引導的稻穀，藉由碰撞進行脫殼，前述稻穀供給部具有與前述葉輪部的前述旋轉軸心方向的寬度對應的寬度，在前述稻穀供給部的外周部設置有引導面，將從前述旋轉軸心方向的一方側運入的稻穀向另一方側引導，前述引導面從前述一方側延伸至前述另一方側，前述葉輪部具備：多個葉片體，係從徑向內方側朝向徑向外方側呈放射狀延伸；以及分散引導部，係使從前述稻穀供給部排出的稻穀沿著前述旋轉軸心方向分散，並向彼此相鄰的前述葉片體之間的空間引導，前述分散引導部具備在前述旋轉軸心方向上並列的多個稻穀通過部，前述稻穀通過部沿著前述旋轉軸心方向具有容許一粒或者多粒稻穀向徑向外方通過的橫向寬度，並且以遍佈周向整個區域的狀態設置。 The characteristic configuration of the rice hulling device of the present invention is that it includes a rice supply unit that discharges the rice imported from the outside in the radial direction, and an impeller unit that is provided along the outer periphery of the rice supply unit to receive the The rice discharged from the rice supply part rotates around a rotation axis located at the center of the rice supply part to guide the rice discharged from the rice supply part radially outward; and the shelling part receives the impeller part The guided rice is hulled by collision, and the rice supply part has the rotation axis center side of the impeller part A width corresponding to the width, a guide surface is provided on the outer peripheral portion of the rice supply portion, and the rice carried from one side of the rotation axis direction is guided to the other side, and the guide surface extends from the one side to the On the other side, the impeller portion includes: a plurality of blade bodies extending radially from the radially inner side toward the radially outer side; and a dispersion guide portion that causes the rice discharged from the rice supply portion to extend along the The direction of the rotation axis is dispersed and guided to the space between the blade bodies adjacent to each other. The dispersion guide portion includes a plurality of rice passage portions juxtaposed in the direction of the rotation axis. The rice passage portions are along the rotation axis The center direction has a lateral width that allows one or more grains of rice to pass radially outward, and is arranged in a state spreading over the entire area in the circumferential direction.

根據本發明，稻穀相對於稻穀供給部從旋轉軸心方向的一方側運入，該運入的稻穀藉由從旋轉軸心方向的一方側延伸至另一方側設置的引導面而向旋轉軸心方向的另一方側引導。並且，將運入的稻穀向徑向外方排出。亦即，在稻穀供給部，即使在稻穀從旋轉軸心方向的一方側一舉運入的情況下，稻穀從一方側延伸至另一方側呈均勻分佈的狀態，從而以分佈不均較小的狀態朝向葉輪部排出。 According to the present invention, the rice is transported from one side of the rotation axis direction relative to the rice supply portion, and the transported rice is directed toward the rotation axis by the guide surface extending from one side to the other side of the rotation axis direction Guide on the other side of the direction. In addition, the imported rice is discharged radially outward. In other words, in the rice supply section, even when the rice is transported in one fell swoop from one side of the rotation axis direction, the rice extends from one side to the other side in a uniformly distributed state, so that the distribution unevenness is small Discharge toward the impeller.

在葉輪部設置有分散引導部，使從稻穀供給部排出的稻穀沿著前述旋轉軸心方向分散。該分散引導部具備在旋轉軸心方向上並列的多個稻穀通過部。由於稻穀通過部是沿著旋轉軸心方向具有僅能供一粒或者多粒稻穀向徑向外方通過之橫向寬度的結構，因此不能從一個稻穀通過部通過而溢出的稻穀依次朝向在旋轉軸心方向上彼此相鄰的稻穀通過部移動，藉此能夠可靠地使其沿著旋轉軸心方向分散。 The impeller portion is provided with a dispersion guide portion to disperse the rice discharged from the rice supply portion along the direction of the rotation axis. The dispersion guide portion includes a plurality of rice passage portions juxtaposed in the direction of the rotation axis. Because the paddy passage is along the rotation axis, it can only supply one or more grains of rice radially outward The horizontal width of the square passes, so that the rice that cannot pass through one of the rice passages and overflows sequentially moves toward the rice passages adjacent to each other in the direction of the rotation axis, thereby reliably making it along the direction of the rotation axis dispersion.

並且，由於稻穀通過部以遍佈周向整個區域的狀態設置，因此即使有時稻穀由稻穀供給部以互相重疊的狀態供給，從稻穀供給部供給的稻穀也能夠伴隨葉輪部的旋轉而無滯留地順利地被引導通過稻穀通過部。其結果，能夠使從稻穀供給部供給的稻穀以沿著旋轉軸心方向分散的狀態無滯留地順利地引導通過。 In addition, since the rice passage portion is provided over the entire circumferential area, even if the rice is supplied by the rice supply portion in an overlapping state, the rice supplied from the rice supply portion can be accompanied by the rotation of the impeller portion without stagnation. It was successfully guided through the paddy passage department. As a result, it is possible to smoothly guide the rice supplied from the rice supply unit in a state of being dispersed along the rotation axis direction without stagnation.

因此，能夠使稻穀以在葉輪部的旋轉軸心方向上盡可能均勻分佈的狀態與脫殼部碰撞，並且有效率地進行作業。 Therefore, it is possible to make the rice collide with the shelling portion in a state of being distributed as uniformly as possible in the direction of the rotation axis center of the impeller portion, and work can be performed efficiently.

本發明較佳為：前述分散引導部具備整流引導路徑，前述整流引導路徑是指，在將稻穀劃分到各稻穀通過部的狀態下將稻穀以整流狀態朝向徑向外方側引導的路徑。 In the present invention, it is preferable that the dispersion guide portion includes a rectification guide path, and the rectification guide path refers to a path that guides the rice toward the radially outward side in a rectified state in a state where the rice is divided into each rice passage portion.

根據本結構，對於被劃分到各稻穀通過部的稻穀，由於由各個稻穀引導部引導的稻穀彼此不互相混雜，藉由整流引導路徑以整流狀態朝向徑向外方側引導，因此能夠以分散於旋轉軸心方向的狀態直接轉移至徑向外方的葉片體。 According to this structure, for the rice divided into each rice passing portion, the rice guided by each rice guiding portion is not mixed with each other, and is guided toward the radially outward side in a rectified state by the rectifying guiding path, so it can be dispersed in The state in the direction of the rotation axis is directly transferred to the blade body radially outward.

本發明較佳為：前述分散引導部以其徑向外側端部靠近前述葉片體的徑向內側端部的狀態設置。 In the present invention, it is preferable that the dispersion guide portion is provided in a state where its radially outer end is close to the radially inner end of the blade body.

根據本結構，由於呈分散引導部與葉片體接近的狀態，因此能夠將由分散引導部以沿著旋轉軸心方向分散的狀態引導的稻穀直接轉移至葉片體，能夠避免轉移時稻穀彼此呈互相重疊的狀態。 According to this structure, since the dispersion guide is close to the blade body Therefore, it is possible to directly transfer the rice guided by the dispersion guide portion in a state of being dispersed along the direction of the rotation axis to the blade body, and it is possible to prevent the rice from overlapping each other during the transfer.

本發明較佳為：在前述稻穀供給部的徑向外側端部與前述分散引導部的徑向內側端部之間形成有稻穀導入用的間隙。 In the present invention, it is preferable that a gap for introducing rice is formed between the radially outer end of the rice supply part and the radially inner end of the dispersion guide part.

根據本結構，稻穀供給部將從外部運入的稻穀向徑向外方排出，分散引導部以接收從該稻穀供給部排出的稻穀並使其分散的方式進行引導。此時，稻穀供給部為位置固定狀態，分散引導部一邊旋轉一邊接收稻穀。藉由形成有稻穀導入用的間隙，能夠從位置固定狀態的稻穀供給部朝向旋轉的分散引導部無滯留地順利地進行稻穀的轉移。 According to this configuration, the rice supply unit discharges the rice imported from the outside in the radial direction, and the dispersing guide unit guides the rice discharged from the rice supply unit to disperse the rice. At this time, the rice supply part is in a fixed position, and the dispersion guide part receives the rice while rotating. By forming the gap for rice introduction, the rice can be smoothly transferred from the rice supply portion in a fixed position to the rotating dispersion guide portion without stagnation.

本發明較佳為：前述分散引導部具備：多個分區形成體，係為了形成前述稻穀通過部，以隔開設定間隔並與前述旋轉軸心正交的姿勢設置；以及多個滑動引導體，係呈放射狀，位於前述各分區形成體之間，前述分區形成體與前述滑動引導體一體連結，在前述稻穀供給部的徑向外側端部與前述滑動引導體的徑向內側端部之間形成有前述稻穀導入用的間隙，前述稻穀供給部的徑向外側端部靠近前述分區形成體的徑向內側端部。 In the present invention, it is preferable that the dispersion guide includes: a plurality of partition forming bodies, which are provided at intervals with a set interval and orthogonal to the rotation axis to form the rice passage portion; and a plurality of sliding guides, Radially located between the partition forming bodies, the partition forming body and the sliding guide are integrally connected, between the radially outer end of the paddy supply portion and the radially inner end of the sliding guide The gap for introducing rice is formed, and the radially outer end of the rice supply part is close to the radially inner end of the partition forming body.

根據本結構，在由與旋轉軸心正交之姿勢的多個分區形成體所劃分出的區域，形成有在旋轉軸心方向上並列的多個稻穀通過部。並且，由於稻穀供給部的徑向外側端部與前述分區形成體的徑向內側端部接近，因此一旦遍佈多個稻穀通過部並分散於旋轉軸心方向後，不會從稻穀供給部與分區形成體之間移動至其他稻穀通過部，而是直接由該稻穀通過部保持。 According to this configuration, a plurality of paddy passages juxtaposed in the direction of the rotation axis are formed in the area divided by the plurality of partition forming bodies in a posture orthogonal to the rotation axis. Moreover, since the radially outer end of the rice feed portion is close to the radially inner end of the aforementioned partition forming body, once the After the two rice passages are dispersed in the rotation axis direction, they are not moved from the rice supply part and the partition forming body to other rice passages, but are held directly by the rice passages.

由於在稻穀供給部與滑動引導體之間形成有稻穀導入用的間隙，因此分散於旋轉軸心方向並被引導至各稻穀通過部的稻穀能夠在該稻穀通過部的內部通過稻穀導入用的間隙並在周向自由地移動。其結果是，稻穀分散於周向，並由多個滑動引導體依次朝向徑向外方引導。 Since the gap for paddy introduction is formed between the paddy supply part and the sliding guide, the paddy scattered in the rotation axis direction and guided to each paddy passage can pass through the paddy introduction gap inside the paddy passage And move freely in the circumferential direction. As a result, the rice is dispersed in the circumferential direction, and is sequentially guided radially outward by the plurality of sliding guide bodies.

藉此，藉由一邊使稻穀維持分散於旋轉軸心方向的狀態一邊由多個滑動引導體依次引導，從而能夠不在稻穀通過部內滯留地朝向葉片體引導，能夠有效率地進行稻穀脫殼作業。 Thereby, by sequentially guiding the plurality of sliding guides while maintaining the state of being dispersed in the rotation axis direction, the rice can be guided toward the blade body without staying in the rice passage portion, and the rice hulling operation can be efficiently performed.

本發明較佳為：前述稻穀供給部具備圓筒狀的稻穀引導體，並且在前述稻穀引導體的前述旋轉軸心方向一端側形成有稻穀入口，並形成有在前述稻穀引導體之周向的一部分區域開口的稻穀排出部。 In the present invention, it is preferable that the rice supply part includes a cylindrical rice guide, and a rice inlet is formed at one end of the rice guide in the direction of the rotation axis, and a circumferential direction of the rice guide is formed A rice discharge part with an open area.

根據本結構，在稻穀供給部，稻穀從形成於具有筒狀空間之圓筒狀之稻穀引導體之旋轉軸心方向一端側的稻穀入口運入。此時，從外部投入的稻穀在筒狀空間的內部以向旋轉軸心方向散開的狀態被運入。並且，運入的稻穀從在稻穀引導體之周向的局部開口所形成的稻穀排出部向徑向外方排出。 According to this structure, in the rice supply part, rice is carried in from the rice inlet formed in one end side of the rotation axis center direction of the cylindrical rice guide body which has a cylindrical space. At this time, the rice thrown in from the outside is carried in the state of being scattered in the direction of the rotation axis in the cylindrical space. In addition, the imported rice is discharged radially outward from the rice discharge portion formed by a partial opening in the circumferential direction of the rice guide.

因此，即使有時從外部一舉投入大量的稻穀，也會從稻穀排出部以預先在旋轉軸心方向上均勻分佈的狀態向葉輪部排出，易於對葉輪部進行使稻穀向旋轉軸心方向的均勻分佈處理。 Therefore, even if a large amount of rice is thrown in one fell swoop from the outside, the rice discharge portion is evenly distributed in the state of the rotation axis in advance to the leaves The wheel portion is discharged, and the impeller portion can be easily distributed evenly in the direction of the rotation axis.

Thereby, the inner surface of the rice guide body 11 forms a guide surface, and guides the imported rice from one side to the other side in the direction of the rotation axis.

如圖3、圖8及圖9所示般，葉輪部6具備：多個葉片體14，係從徑向內方側朝向外方側呈放射狀延伸；以及分散引導部15，係將從稻穀供給部7排出的稻穀M沿著旋轉軸心方向分散，並向彼此相鄰的葉片體之間的空間引導。 As shown in FIGS. 3, 8 and 9, the impeller portion 6 includes: a plurality of blade bodies 14 extending radially from the radially inner side toward the outer side; and a dispersion guide portion 15 that extends from the rice The rice M discharged from the supply unit 7 is dispersed in the direction of the rotation axis and guided to the space between the blade bodies adjacent to each other.

對於由稻穀供給部7供給的稻穀M，多個葉片體14係一邊藉由沿著徑向延伸的滑動引導面16來進行滑動引導，一邊藉由伴隨旋轉的離心力而向徑向外方引導。 With respect to the rice M supplied by the rice supply part 7, the plurality of blade bodies 14 are guided radially outward by centrifugal force accompanying rotation while being slidingly guided by the sliding guide surface 16 extending in the radial direction.

如圖6、圖8及圖10所示般，各葉片體14具備由板狀的金屬材料所形成之大致U字形的主體部14a，藉由該主體部14a，使中央之寬度較寬的面形成滑動引導面16。除了形成有滑動引導面16的主體部14a之外，在滑動引導面16的相反側與主體部14a一體地連結有形成背側引導面17的背面形成部14b。在主體部14a與背面形成部14b之間形成有越往徑向外方側越往周向擴寬的開口14c。 As shown in FIGS. 6, 8 and 10, each blade body 14 includes a substantially U-shaped main body portion 14 a formed of a plate-shaped metal material, and by the main body portion 14 a, a surface with a wider width in the center is formed The sliding guide surface 16 is formed. In addition to the main body portion 14 a on which the slide guide surface 16 is formed, a back surface forming portion 14 b forming the back side guide surface 17 is integrally connected to the main body portion 14 a on the opposite side of the slide guide surface 16. Between the main body portion 14a and the back surface forming portion 14b, an opening 14c is formed that widens in the circumferential direction as it goes outward in the radial direction.

如圖11及圖12所示般，在葉片體14的旋轉軸心方向兩側部分別設置有由合成樹脂材料所構成之圓板狀的支承板18、19，各葉片體14之左右兩側的側面14d係與各支承板18、19以螺栓連結。 As shown in FIGS. 11 and 12, disc-shaped support plates 18 and 19 made of synthetic resin materials are provided on both sides of the blade body 14 in the rotation axis direction, and the left and right sides of each blade body 14 are provided. The 14d The support plates 18 and 19 are connected by bolts.

如圖5、圖6及圖8所示般，在多個葉片體14各自的徑向外方側部位，以與葉片體14一體旋轉的狀態設置有作為內側脫殼部的稻穀引導元件21，稻穀引導元件21具有與滑動引導面16交叉的碰撞面20。具體而言，碰撞面20相對於滑動引導面16，係越往徑向外方側越向旋轉方向下游側傾斜。 As shown in FIG. 5, FIG. 6 and FIG. 8, at the radially outer side portion of each of the plurality of blade bodies 14, a rice guide element 21 as an inner shelling portion is provided while rotating integrally with the blade body 14, The rice guide element 21 has a collision surface 20 that intersects the sliding guide surface 16. Specifically, the collision surface 20 is inclined with respect to the sliding guide surface 16 toward the downstream side in the rotation direction as it goes radially outward.

稻穀引導元件21係使用作為軟質的合成樹脂之由氨基甲酸乙酯所構成的軟質材料以一體成形來構成。該稻穀引導組件21的硬度設定為比襯圈9的硬度還低的值。當硬度過高時，稻穀受到損傷的可能性大。另一方面，當硬度過低時，存在有脫殼性能降低的不利情況。因此，根據實驗等，將稻穀引導組件21的硬度設定為適當的值，以使稻穀損傷的可能性小且脫殼性能不變低。由於稻穀與碰撞面20碰撞時的速度、角度比襯圈9易於控制，因此即使將硬度設定得稍低，也能夠維持脫殼性能。 The rice guide element 21 is formed by integral molding using a soft material composed of urethane as a soft synthetic resin. The hardness of the rice guide assembly 21 is set to a value lower than the hardness of the collar 9. When the hardness is too high, the rice is likely to be damaged. On the other hand, when the hardness is too low, there is a disadvantage that the dehulling performance decreases. Therefore, according to experiments or the like, the hardness of the rice guide assembly 21 is set to an appropriate value so that the possibility of damage to the rice is small and the hulling performance is not low. Since the speed and angle when the rice collides with the collision surface 20 are easier to control than the collar 9, it is possible to maintain the shelling performance even if the hardness is set slightly lower.

如圖6、圖11及圖12所示般，稻穀引導元件21的旋轉軸心方向兩側係藉由兩根螺栓22連結於各支承板18、19。為了對由軟質材料所構成的稻穀引導元件21可靠地進行螺栓鎖緊，係具備金屬製的內螺紋構件23，該內螺紋構件23係覆蓋各螺栓22的外周部且遍佈稻穀引導組件21之旋轉軸心方向的全範圍地延伸。就一對內螺紋構件23而言，其旋轉軸心方向一端部彼此藉由連結部24一體連結，相對於形成於稻穀引導組件21的插通孔25，係從旋轉軸心方向一端部側***來進行裝接。 As shown in FIGS. 6, 11, and 12, the two sides of the paddle guide element 21 in the rotation axis direction are connected to the support plates 18 and 19 by two bolts 22. In order to securely lock the rice guide element 21 made of a soft material, a metal internal thread member 23 is provided. The internal thread member 23 covers the outer periphery of each bolt 22 and spreads over the rotation of the rice guide assembly 21 It extends over the entire range of the axis. With respect to the pair of internally threaded members 23, one end portion in the direction of the rotation axis is integrally connected to each other by the connecting portion 24, and is opposed to the insertion hole 25 formed in the rice guide assembly 21, It is inserted from one end side in the direction of the axis of rotation for attachment.

如圖10所示般，稻穀引導組件21係以與葉片體14的徑向外方側連續相連的方式，以基端部21a進入葉片體14之開口14c的狀態配置。於稻穀引導組件21，設有延伸設置部21b，該延伸設置部21b係從基端部21a越往徑向外方側越朝向旋轉方向下游側延伸。 As shown in FIG. 10, the rice guide assembly 21 is continuously connected to the radially outer side of the blade body 14, and is arranged in a state where the base end portion 21 a enters the opening 14 c of the blade body 14. The rice guide assembly 21 is provided with an extension portion 21b extending from the base end portion 21a toward the radially outer side toward the downstream side in the rotation direction.

在延伸設置部21b的徑向內方側形成有碰撞面20，該碰撞面20相對於葉片體14的滑動引導面16，係越往徑向外方側越向旋轉方向下游側傾斜。該碰撞面20係供由葉片體14的滑動引導面16所引導滑動的稻穀碰撞，從而進行脫殼處理。 A collision surface 20 is formed on the radially inner side of the extension portion 21b, and the collision surface 20 is inclined toward the downstream side in the rotation direction toward the radially outer side with respect to the sliding guide surface 16 of the blade body 14. This collision surface 20 is for the rice guided by the sliding guide surface 16 of the blade body 14 to collide to perform the shelling process.

在葉片體14的滑動引導面16與碰撞面20之間形成有姿勢變更面26，以越往徑向外方側越位於旋轉方向下游側的方式彎曲。對於由滑動引導面16引導至徑向外方的稻穀M，該姿勢變更面26係一邊進行姿勢變更，一邊向碰撞面20引導。 An attitude changing surface 26 is formed between the sliding guide surface 16 of the blade body 14 and the collision surface 20, and is curved so as to be located on the downstream side in the rotation direction toward the radially outer side. For the rice M guided by the slide guide surface 16 to the radially outer side, the posture changing surface 26 guides the collision surface 20 while changing the posture.

如圖10所示般，藉由形成有姿勢變更面26，使由葉片體14的滑動引導面16所引導滑動之稻穀M的姿勢變更，從而避免稻穀M最硬的部位亦即胚芽所在之前端變細形的一端部部位與碰撞面20碰撞。 As shown in FIG. 10, by forming the posture changing surface 26, the posture of the rice M guided and slid by the sliding guide surface 16 of the blade body 14 is changed to avoid the hardest part of the rice M, that is, the front end of the germ One end portion of the tapered shape collides with the collision surface 20.

在稻穀引導組件21之與碰撞面20的徑向內方側鄰接的部位，係以相對於姿勢變更面26凹入的狀態形成有凹入面27。在凹入面27與姿勢變更面26的徑向外端部之間，在周向上形成有臺階，藉由採用由姿勢變更面26所引導的稻穀越過該臺階並以被朝向碰撞面20投擲的狀態引導的結構，從而提高對碰撞面20的撞擊力。 A concave surface 27 is formed in a portion of the rice guide unit 21 adjacent to the radially inner side of the collision surface 20 in a state of being concave with respect to the posture changing surface 26. Between the concave surface 27 and the radially outer end of the posture changing surface 26, a step is formed in the circumferential direction. The guided rice paddles over the step and is guided in a state of being thrown toward the collision surface 20, thereby increasing the impact force against the collision surface 20.

在稻穀引導組件21，設置有投擲作用面28，前述投擲作用面28係將與碰撞面20碰撞後的處理物朝向外側的襯圈9投擲。投擲作用面28係以與碰撞面20相連的狀態形成，以比碰撞面20大的傾斜角度且越往徑向外方側越位於旋轉方向下游側的方式傾斜。 The rice guide assembly 21 is provided with a throwing action surface 28 that throws the processed object that collides with the collision surface 20 toward the outer collar 9. The throwing action surface 28 is formed in a state of being connected to the collision surface 20, and is inclined so as to be larger in the angle of inclination than the collision surface 20 and further to the radially outer side toward the downstream side in the rotation direction.

如圖10所示般，藉由具備有投擲作用面28，與碰撞面20碰撞後的處理物係藉由投擲作用面28的投擲作用，被以盡可能接近外側之襯圈9之切線方向的角度朝向襯圈9拋出。其結果，處理物被拋出並與襯圈9碰撞時，撞擊力變低，糙米、稻穀碎裂或胚芽部分脫落變成脫芽狀態等處理物損傷的可能性較小。 As shown in FIG. 10, by having the throwing action surface 28, the processed object after colliding with the collision surface 20 is thrown by the throwing action surface 28 as close as possible to the tangential direction of the outer liner 9 The angle is thrown towards the collar 9. As a result, when the processed object is thrown and collides with the collar 9, the impact force becomes low, and the processed object is less likely to be damaged, such as brown rice, broken rice, or a part of the germ falling into a de-budded state.

如圖8、圖10所示般，稻穀引導組件21與鄰接於旋轉方向下游側的葉片體14係沿著旋轉方向重疊。具體而言，稻穀引導組件21之延伸設置部21b的旋轉方向下游側端部位置L1位於比與旋轉方向下游側鄰接之葉片體14的旋轉方向上游側端部位置L2更靠近旋轉方向下游側的位置。亦即，稻穀引導組件21係以與鄰接於旋轉方向下游側的葉片體14在旋轉方向上重疊的狀態設置，稻穀引導元件21與葉片體14之間的間隔設定得狹窄。而且，在稻穀引導組件21的徑向外端部形成有外側引導面29，該外側引導面29係設定為與襯圈9的內周面大致平行。 As shown in FIGS. 8 and 10, the rice guide assembly 21 overlaps the blade body 14 adjacent to the downstream side in the rotation direction along the rotation direction. Specifically, the rotation direction downstream end position L1 of the extending portion 21b of the rice guide assembly 21 is located closer to the rotation direction downstream side than the rotation direction upstream end position position L2 of the blade body 14 adjacent to the rotation direction downstream side position. That is, the rice guide assembly 21 is provided in a state of overlapping with the blade body 14 adjacent to the downstream side in the rotation direction in the rotation direction, and the interval between the rice guide element 21 and the blade body 14 is set to be narrow. Furthermore, an outer guide surface 29 is formed at the radially outer end of the rice guide assembly 21, and this outer guide surface 29 is set to be substantially parallel to the inner circumferential surface of the collar 9.

在由彼此相鄰的兩個分區形成構件30所圍成的區域，形成有一個稻穀通過部36。稻穀通過部36係沿著旋轉軸心方向，具有容許一粒稻穀向徑向外方通過的橫向寬度，並以在旋轉軸心方向並列的狀態分割形成有多個。具體而言，一個稻穀通過部36的橫向寬度係設定為比稻穀M之長尺寸方向的寬度還窄，且比稻穀M之短尺寸方向的寬度還寬。稻穀通過部36係以遍佈周向整個區域的狀態設置。藉此，稻穀通過部36係被多個滑動引導構件31在周向上分區為多個區域。 In a region surrounded by two partition forming members 30 adjacent to each other, a rice passage 36 is formed. The 36 series of rice passage The direction of the axis of rotation has a lateral width that allows one grain of rice to pass radially outward, and a plurality of rice are divided in a state of being aligned in the direction of the axis of rotation. Specifically, the width of one rice passage 36 is set to be narrower than the width of the rice M in the long direction and wider than the width of the rice M in the short direction. The rice passage 36 is provided in a state of spreading over the entire area in the circumferential direction. As a result, the rice passage portion 36 is divided into a plurality of regions by the plurality of slide guide members 31 in the circumferential direction.

分散引導部15具備整流引導路徑Q，前述整流引導路徑Q為以下路徑，亦即，將通過各稻穀通過部36的稻穀M在劃分到各稻穀通過部36的狀態下，以整流狀態朝向徑向外方側引導。 The decentralized guide portion 15 includes a rectification guide path Q, which is a path that divides the rice M passing through each rice passage portion 36 into the rice passage portions 36 in a rectified state toward the radial direction Foreign side guidance.

The area surrounded by the partition forming member 30 and the slide guide member 31 is formed from the position of the rice supply portion 7 close to the outer peripheral portion of the rice guide body 11 to the radially inner end of the plurality of blade bodies 14 and is formed to be long In the shape of a strip, a rectification guide path Q is formed by this radially long path, and has a function of guiding the rice in a rectified state toward the radially outward side in a state where it is divided for each rice passage portion 36.

如圖13所示般，分散引導部15的分區形成構件30和滑動引導構件31係分別以徑向外側端部靠近多個葉片體14之徑向內側端部的狀態設置。並且，在稻穀供給部7的徑向外側端部與分散引導部15之滑動引導構件31的徑向內側端部之間形成有稻穀導入用的間隙S。稻穀供給部7的徑向外側端部與分區形成構件30的徑向內側端部之間接近。 As shown in FIG. 13, the partition forming member 30 and the sliding guide member 31 of the dispersion guide 15 are respectively provided in a state where the radially outer end is close to the radially inner end of the plurality of blade bodies 14. Moreover, the sliding guide member 31 at the radially outer end of the rice feeder 7 and the dispersion guide 15 A gap S for introducing rice is formed between the radially inner ends. The radially outer end of the rice feeder 7 is close to the radially inner end of the partition forming member 30.

如圖5及圖7所示般，在連結固定多個滑動引導構件31的一對連結構件32、33中，位於與主體外殼1相反側(外側)的外側連結構件32係藉由分散配置於周向的多個螺栓37來連結於一對支承板18、19中之位於與主體外殼1相反側(外側)的外側支承板18。多個螺栓37係焊接固定於外側連結構件32，插通至形成於外側支承板18的螺紋插通孔38，且插通至設置於外側支承板18之外側的外部安裝板39，並從外方側藉由螺帽40鎖緊固定。藉此，使分散引導部15一體固定於外側支承板18。 As shown in FIGS. 5 and 7, of the pair of connecting members 32 and 33 that connect and fix the plurality of sliding guide members 31, the outer connecting members 32 located on the opposite side (outer side) from the main body casing 1 are dispersedly arranged in A plurality of bolts 37 in the circumferential direction are connected to the outer support plate 18 on the opposite side (outer side) to the main body case 1 among the pair of support plates 18 and 19.

As a result, the dispersion guide 15 is integrally fixed to the outer support plate 18.

如圖2、圖9所示般，設置有驅動軸41，係從主體外殼1的內部開始從流下引導部3和稻穀供給部7的中心部通過並延伸至稻穀脫殼部4的外側支承板18。雖未詳述，但根據需要，將驅動軸41的數個部位由軸承旋轉自由地支承，並且與設置於主體外殼1之內部的電動馬達5連動連結。 As shown in FIGS. 2 and 9, a drive shaft 41 is provided, which extends from the inside of the main body case 1 from the center of the downflow guide 3 and the rice supply part 7 to the outer support plate of the rice hulling part 4 18. Although not described in detail, if necessary, several parts of the drive shaft 41 are rotatably supported by bearings, and interlocked with the electric motor 5 provided inside the main body casing 1.

如圖5、圖9所示般，在驅動軸41之與主體外殼1相反側的端部連結有軸連結構件42。軸連結構件42具備：軸套部44，係與形成於外側支承板18的插通孔43嵌合裝接；以及圓板狀的安裝部45，係連結於軸套部44的旋轉軸心方向內方側。 As shown in FIGS. 5 and 9, a shaft connecting member 42 is connected to the end of the drive shaft 41 opposite to the main body casing 1. The shaft coupling member 42 includes: a sleeve portion 44 that is fitted and attached to the insertion hole 43 formed in the outer support plate 18; and a disk-shaped mounting portion 45 that is connected to the rotation axis direction of the sleeve portion 44 Inner side.

驅動軸41係以可傳遞轉矩的方式嵌合連接於軸套部 44，且藉由螺紋防止脫落。並且，安裝部45藉由分散配置於周向的多個螺栓46來連結於外側支承板18。多個螺栓46係焊接固定於軸連結構件42一側，插通至形成於外側支承板18的螺紋插通孔47，且插通至設置於外側支承板18之外側的外部安裝板39，並從外方側藉由螺帽48鎖緊固定。藉此，使驅動軸41與外側支承板18連動連結。 The drive shaft 41 is fitted and connected to the sleeve portion in a manner that can transmit torque 44, and prevent falling off by thread. In addition, the mounting portion 45 is connected to the outer support plate 18 by a plurality of bolts 46 distributed in the circumferential direction. A plurality of bolts 46 are welded and fixed to the shaft connecting member 42 side, are inserted into the screw insertion holes 47 formed in the outer support plate 18, and are inserted into the outer mounting plate 39 provided outside the outer support plate 18, and The nut 48 is locked and fixed from the outside. As a result, the drive shaft 41 and the outer support plate 18 are linked together.

從以上的說明可以明確得知，多個葉片體14、多個稻穀引導組件21以及各支承板18、19各自被螺栓連結固定為一體，並且分散引導部15係一體固定於外側支承板18，進而使驅動軸41與外側支承板18連動連結。藉此，使葉輪部6設置為一體連結有上述各構件，並繞著驅動軸41的軸心(=旋轉軸心X)旋轉操作自如。 It is clear from the above description that the plurality of blade bodies 14, the plurality of rice guide assemblies 21, and the support plates 18, 19 are each bolted and fixed as one body, and the dispersion guide 15 is integrally fixed to the outer support plate 18, Furthermore, the drive shaft 41 and the outer support plate 18 are linked together. Thereby, the impeller portion 6 is provided so that the above-mentioned members are integrally connected, and can rotate freely around the axis (=rotation axis X) of the drive shaft 41.

從稻穀供給部7的稻穀排出部13所排出的稻穀M，係被供給至稻穀供給部7的徑向外側端部與分散引導部15的徑向內側端部之間。當葉輪部6旋轉時，供給至稻穀供給部7的徑向外側端部與分散引導部15的徑向內側端部之間的稻穀M，係被以分散向正在旋轉之分散引導部15的多個稻穀通過部36的狀態朝向徑向外方引導。 The rice M discharged from the rice discharge portion 13 of the rice supply portion 7 is supplied between the radially outer end portion of the rice supply portion 7 and the radially inner end portion of the dispersion guide portion 15. When the impeller portion 6 rotates, the rice M supplied between the radially outer end portion of the rice feed portion 7 and the radially inner end portion of the dispersing guide portion 15 is dispersed to the rotating dispersing guide portion 15 much. The state of each rice passage portion 36 is guided radially outward.

由流下引導部3引導流入至稻穀引導體11的稻穀M係從稻穀排出部13向外方排出。此時，容許稻穀M在旋轉軸心方向一粒一粒依次進入一個稻穀通過部36。如此一來，由於對稻穀通過部36之沿著旋轉軸心方向的寬度係設置為限制一粒一粒進入的寬度，因此從稻穀排出部 13排出的稻穀係以均勻分散於旋轉軸心方向的狀態被引導至在旋轉軸心方向並列的多個稻穀通過部36。藉此，使前述稻穀分散於旋轉軸心方向。而且，藉由使分區形成構件30旋轉，利用分區形成構件30與稻穀M的摩擦，能夠將稻穀的姿勢統一為使稻穀M的長尺寸方向沿著稻穀供給部7的徑向的姿勢。 The rice M system guided by the downflow guide 3 and flowing into the rice guide 11 is discharged from the rice discharge part 13 to the outside. At this time, the rice M is allowed to enter the rice passage portion 36 one by one in the direction of the rotation axis. In this way, since the width of the rice passage portion 36 along the direction of the rotation axis is set to a width that restricts the entry of each grain, the rice discharge section The rice system discharged at 13 is guided to a plurality of rice passage portions 36 juxtaposed in the direction of the rotation axis while being uniformly dispersed in the direction of the rotation axis. This disperses the rice in the direction of the rotation axis. Further, by rotating the partition forming member 30 and the friction between the partition forming member 30 and the rice M, the posture of the rice can be unified so that the long direction of the rice M follows the radial direction of the rice supply portion 7.

由於稻穀供給部7的徑向外側端部與分區形成構件30的徑向內側端部之間接近，因此能夠阻止從稻穀排出部13向外方排出時，分散於旋轉軸心方向並進入一個稻穀通過部36之後，朝向在旋轉軸心方向彼此相鄰的稻穀通過部36移動。 Since the radially outer end of the rice feeder 7 and the radially inner end of the partition forming member 30 are close to each other, it is possible to prevent the rice discharge part 13 from being scattered outward in the rotation axis direction and entering one rice paddle After passing the portion 36, it moves toward the rice passing portion 36 adjacent to each other in the direction of the rotation axis.

由於在稻穀供給部7的徑向外側端部與滑動引導構件31的徑向內側端部之間形成有稻穀導入用的間隙S，因此分散於旋轉軸心方向的稻穀係伴隨葉輪部6的旋轉，從稻穀供給部7與滑動引導構件31之間的間隙S通過並分散於周向。稻穀M係分散於周向並在一個稻穀通過部36內被依次引導進入稻穀通過部36。被引導進入稻穀通過部36的稻穀M係由呈放射狀設置的滑動引導構件31承接，並藉由伴隨旋轉的離心力朝向徑向外方引導。 Since a gap S for introducing rice is formed between the radially outer end of the rice feeder 7 and the radially inner end of the slide guide member 31, the rice system dispersed in the direction of the rotation axis accompanies the rotation of the impeller 6 , Passing through the gap S between the rice supply portion 7 and the slide guide member 31 and dispersed in the circumferential direction. The rice M system is dispersed in the circumferential direction and guided into the rice passage 36 in sequence in one rice passage 36. The rice M guided into the rice passage portion 36 is received by the sliding guide member 31 provided radially, and is guided radially outward by centrifugal force accompanying rotation.

如圖13、圖14所示般，由於分區形成構件30和滑動引導構件31各自的徑向外側端部靠近葉片體14的徑向內側端部，因此在各稻穀通過部36的內部被沿著徑向引導的稻穀M彼此互不干擾，被直接以整流狀態朝向徑向外方側的葉片體14引導。 As shown in FIGS. 13 and 14, since the radially outer end portions of the partition forming member 30 and the slide guide member 31 are close to the radially inner end portion of the blade body 14, the inside of each rice passage portion 36 is followed The rice M guided radially does not interfere with each other, and is directly guided toward the blade body 14 on the radially outer side in a rectified state.

在葉片體14，直接繼續接收從分散引導部15引導的稻穀M，一邊藉由滑動引導面16承接並進行滑動引導，一邊藉由伴隨旋轉的離心力向徑向外方引導。如圖10所示般，由滑動引導面16滑動引導的稻穀係一邊藉由形成於徑向外端部的姿勢變更面26來變更朝向，一邊被朝向稻穀引導組件21的碰撞面20引導。 The blade body 14 continues to receive the rice M guided from the dispersing guide portion 15 directly, and is guided to the outside in the radial direction by centrifugal force accompanying rotation while receiving and sliding guide by the sliding guide surface 16. As shown in FIG. 10, the rice system slidingly guided by the sliding guide surface 16 is guided toward the collision surface 20 of the rice guide assembly 21 while changing the direction by the posture changing surface 26 formed at the radially outer end.

當稻穀M與碰撞面20碰撞時，藉由該撞擊進行脫殼處理，使稻穀M被分離成稻穀殼和糙米。但是，也存在一部分稻穀M未脫殼而殘留的情況。包含稻穀殼、糙米及未處理稻穀等的處理物伴隨著葉輪部6的旋轉，被投擲作用面28朝向外側的襯圈9投擲，並藉由外側的襯圈9再次進行脫殼處理。 When the rice M collides with the collision surface 20, the shelling treatment is performed by the impact, so that the rice M is separated into rice husk and brown rice. However, some rice M may remain without being hulled. The treatment including the rice husk, brown rice, and untreated rice is thrown toward the outer collar 9 by the throwing action surface 28 as the impeller portion 6 rotates, and the outer collar 9 is again subjected to shelling treatment.

與外側的襯圈9碰撞後的處理物係利用伴隨高速旋轉之葉輪部6的旋轉所產生的送風力，藉由輸送引導部8a被輸送至外部之未圖示的分選裝置。在分選裝置中，進行分選處理以分離稻穀殼和糙米。需要說明的是，上述結構的稻穀脫殼裝置由於能夠提高脫殼率，因此對於分選裝置，可以省略以往的稻穀脫殼裝置所需的用於分選糙米和未處理稻穀之特殊的分選機構，能夠實現分選裝置的小型化、結構簡化。 The processing object after colliding with the outer collar 9 is sent to the outside by a conveying guide portion 8a to a sorting device (not shown) which is conveyed by the conveying guide portion 8a using the wind force generated by the rotation of the impeller portion 6 rotating at a high speed. In the sorting device, a sorting process is performed to separate rice husks and brown rice. It should be noted that since the rice hulling device of the above structure can increase the hulling ratio, the sorting device can omit the special sorting for separating brown rice and untreated rice, which is required by the conventional rice hulling device. The mechanism can achieve the miniaturization and simplified structure of the sorting device.

反復進行稻穀脫殼處理，當由稻穀碰撞而引起構件磨損時，需要更換磨損的構件，但在上述結構中，作為大型構件的襯圈9、葉片體14早期磨損的可能性小，更換頻率高的僅是稻穀引導元件21，存在以低成本就能夠應對的優點。 The rice hulling process is repeated, and when the components are worn due to rice collision, the worn components need to be replaced. However, in the above-mentioned structure, the gasket 9 and the blade body 14 which are large-sized components are less likely to be worn early and the replacement frequency is high. Is only the rice guide element 21, which can cope with low cost The advantages.
