Description

本発明は、脱穀装置に備える扱胴に係るものである。   The present invention relates to a handling cylinder provided in a threshing apparatus.

従来、扱室に軸装した扱胴を、その前部を前部が細いテーパー部に形成し、後部を前後の側枠間に渡し掛けた桟部材と、この桟部材に回転方向に隣接する桟部材の間を塞ぐ遮蔽部材により多角形状の胴筒部により形成した構成は、公知である（特許文献１）。   Conventionally, a handling cylinder that is mounted in a handling chamber has a front portion formed into a tapered portion with a thin front portion and a rear portion passed between front and rear side frames, and the crosspiece member is adjacent to the crosspiece member in the rotational direction. The structure formed by the polygonal cylinder part by the shielding member which block | closes between a crosspiece member is well-known (patent document 1).

特開２０１１−１８２６５３号公報JP 2011-182653 A

前記公知例は、単に、回転方向に隣接する桟部材の間を遮蔽部材で塞いでドラム部を形成しているので、ドラム部は径方向の支持が無く、扱室内の負荷が大きくなると変形するという課題がある。   In the known example, the drum portion is formed by simply blocking between the crosspiece members adjacent to each other in the rotation direction with the shielding member. Therefore, the drum portion is not supported in the radial direction, and deforms when the load in the handling chamber increases. There is a problem.

また、扱歯の回転軌跡と扱胴の外周との間に形成される空間が狭く、脱穀処理効率が低く、詰まりが発生して負荷を大きくして、この点でも、変形するという課題がある。   In addition, there is a problem that the space formed between the rotation locus of the tooth handling and the outer periphery of the handling cylinder is narrow, the threshing efficiency is low, clogging occurs, the load is increased, and this point is also deformed. .

即ち、扱胴の周囲に形成される空間は、桟部材に取付けた扱歯の先端の移動軌跡と、遮蔽部材の外面との間の空間となるが、遮蔽部材の内面を遮蔽部材で連結しているので、扱胴の周囲に形成される空間は、扱歯の高さと実質同一になる。   That is, the space formed around the handle cylinder is a space between the movement locus of the tip of the tooth handle attached to the crosspiece member and the outer surface of the shielding member, but the inner surface of the shielding member is connected by the shielding member. Therefore, the space formed around the handling cylinder is substantially the same as the height of the tooth handling.

本願は、扱胴の構成を工夫し、扱胴の変形を防止すると共に、扱歯による被処理物を処理できる空間を広くして、脱穀処理効率を向上させるようにしたものである。   In the present application, the structure of the handling cylinder is devised, the deformation of the handling cylinder is prevented, and the space in which the object to be processed by the teeth can be processed is widened to improve the threshing efficiency.

And it is obtained by a thresher in which a shielding plate (45) between the outer peripheral surface and each 扱歯 support members of the drum portion (27) (25).

請求項２記載の発明は、前記ドラム部（２７）が、四辺を有するように成形された二つの板部材（３３）を向い合せてボルト固定して構成される請求項１記載の扱胴としたものである。   The invention according to claim 2 is characterized in that the drum portion (27) is configured by facing and fixing two plate members (33) formed so as to have four sides with bolts. It is a thing.

請求項１記載の発明によれば、扱胴の周囲に広い空間２９が形成されるので、脱穀処理効率を向上させると共に、詰まり発生を防止して扱胴の変形を防止できる。   According to the first aspect of the present invention, since the wide space 29 is formed around the handling cylinder, it is possible to improve the threshing processing efficiency and to prevent clogging and deformation of the handling cylinder.

また、ドラム部２７は強度の高い頂部３０で脱穀処理物からの力を受けるので、扱胴の変形を防止できる。   Moreover, since the drum part 27 receives the force from a threshing processed material at the top part 30 with high intensity | strength, it can prevent a deformation | transformation of a handling cylinder.

そして、中間仕切板３８により扱歯支持部材２５の中間部を支持するので、扱歯２０の支持強度を向上させることができる。   And since the intermediate part of the tooth handling support member 25 is supported by the intermediate partition plate 38, the support strength of the tooth handling 20 can be improved.

Is connected to the handling chamber 22 of the threshing device 3.

１０は脱穀装置３の唐箕、１１は同揺動選別棚、１２は移送棚部、１３はシーブ、１４はストローラック、１５は一番コンベア、１６は二番コンベアである（図２）。   Reference numeral 10 denotes a tang of the threshing device 3, 11 is the swing sorting shelf, 12 is a transfer shelf, 13 is a sheave, 14 is a stroller, 15 is a first conveyor, and 16 is a second conveyor (FIG. 2).

前記脱穀装置３は、上部に扱歯２０を有する扱胴２１を略水平に軸装した扱室２２を設ける。   The threshing device 3 is provided with a handling chamber 22 in which a handling cylinder 21 having a handling tooth 20 on the upper part thereof is mounted substantially horizontally.

扱胴２１は、扱歯２０を複数設けた扱歯支持部材２５を、扱胴軸２６と径方向（放射方向）に所定間隔をおいて配置すると共に、扱歯支持部材２５は互いに周方向（回転方向）に所定間隔を置いて配置し（図４）、扱歯支持部材２５の内側に多角形状のドラム部２７を設け、ドラム部２７と扱歯支持部材２５とは、ドラム部２７の頂部（角部）を扱胴軸２６の周方向で、扱歯支持部材２５間に臨ませて配置する。   The handle 21 has a tooth support member 25 provided with a plurality of teeth 20 arranged at a predetermined interval in the radial direction (radial direction) with respect to the handle shaft 26 and the tooth support members 25 are circumferentially connected to each other ( 4), a polygonal drum portion 27 is provided inside the tooth handling support member 25. The drum portion 27 and the tooth handling support member 25 are the top of the drum portion 27. The (corner portion) is disposed in the circumferential direction of the handle cylinder shaft 26 so as to face the tooth support member 25.

そのため、扱歯支持部材２５の内側にドラム部２７を設けているので、扱胴２１の剛性を向上させ、扱歯支持部材２５間から扱歯支持部材２５とドラム部２７の外周面との間の空間２９に入り込んだ脱穀物によって、ドラム部２７が変更するのを防止する。   Therefore, since the drum portion 27 is provided inside the tooth handling support member 25, the rigidity of the handling barrel 21 is improved, and between the tooth handling support member 25 and the outer peripheral surface of the drum portion 27. The drum portion 27 is prevented from being changed by the cerealing that has entered the space 29.

２８はドラム部２７の頂部３０間の辺部（面部）である。   Reference numeral 28 denotes a side portion (surface portion) between the top portions 30 of the drum portion 27.

換言すると、扱胴２１は、複数の扱歯２０を取付けたパイプ状の扱歯支持部材２５を扱胴２１の回転方向に複数配置し、複数の扱歯支持部材２５の内部に扱胴２１のドラム部２７を設ける。   In other words, the handle cylinder 21 includes a plurality of pipe-shaped tooth support members 25 attached with a plurality of handle teeth 20 in the rotational direction of the handle cylinder 21, and the handle cylinder 21 is disposed inside the plurality of tooth handle support members 25.

It is only necessary to make the installation easier.

前記扱歯支持部材２５は、その前後両端にブラケット３６を固定し、ブラケット３６はボルト３７により前側フランジ３１と後側フランジ３２とに取付ける。   The tooth handling support member 25 has brackets 36 fixed to both front and rear ends thereof, and the bracket 36 is attached to the front flange 31 and the rear flange 32 by bolts 37.

そのため、扱歯２０の取付を容易にする。   Therefore, attachment of the tooth handling 20 is facilitated.

扱胴２１のドラム部２７には、放射方向に突出する中間仕切板３８を所定間隔（等間隔）をおいて複数設け、この中間仕切板３８に前記扱歯支持部材２５を取付ける（なお、作図上、同一部分に符号「３１」と「３８」を付している。）。   A plurality of intermediate partition plates 38 projecting in the radial direction are provided on the drum portion 27 of the handle cylinder 21 at a predetermined interval (equal interval), and the tooth support member 25 is attached to the intermediate partition plate 38 (note that drawing) Above, the same parts are denoted by reference numerals “31” and “38”).

即ち、扱胴軸２６にはドラム部２７の外周に延設される中間仕切板３８を設け、該中間仕切板３８に前記扱歯支持部材２５を連結する。   That is, an intermediate partition plate 38 extending on the outer periphery of the drum portion 27 is provided on the handle cylinder shaft 26, and the tooth support member 25 is connected to the intermediate partition plate 38.

そのため、中間仕切板３８により扱歯支持部材２５の中間部を支持するので、扱歯２０の支持強度を向上させられる。   Therefore, since the intermediate part of the tooth handling support member 25 is supported by the intermediate partition plate 38, the support strength of the tooth handling 20 can be improved.

扱胴２１は、ドラム部２７の先端部に後側が大径となる円錐状のテーパー部３９に形成した構成とし、扱歯２０を複数設けた扱歯支持部材２５を、扱胴軸２６と径方向（放射方向）に所定間隔をおいて配置すると共に、ドラム部２７の前端の前側フランジ３１とドラム部２７の後端の後側フランジ３２に渡しかけて設け、扱歯支持部材２５の中間を扱胴軸２６に支持する中間仕切板３８を設け、扱歯支持部材２５は前側フランジ３１と後側フランジ３２と中間仕切板３８とにブラケット３６により連結する構成とし、前記中間仕切板３８は一対のブラケット３６により挟持して連結する（図６）。   The handle cylinder 21 has a conical taper portion 39 having a large rear diameter at the tip of the drum portion 27, and a tooth support member 25 provided with a plurality of handle teeth 20 is connected to the handle shaft 26 in diameter.

即ち、同心上に配置した扱歯支持部材２５の内側に、ドラム部２７の辺部２８が位置する。   That is, the side portion 28 of the drum portion 27 is positioned inside the tooth handling support member 25 arranged concentrically.

ドラム部２７の外周面から扱歯支持部材２５に向かって延出した遮蔽プレート４５でドラム部２７と扱歯支持部材２５の間を塞ぐ構成とする（図４）。   It is set as the structure which blocks between the drum part 27 and the tooth-handling support member 25 with the shielding plate 45 extended toward the tooth-handling support member 25 from the outer peripheral surface of the drum part 27 (FIG. 4).

即ち、ドラム部２７の辺部２８と各扱歯支持部材２５との間に遮蔽プレート４５を設ける。   That is, the shielding plate 45 is provided between the side portion 28 of the drum portion 27 and each tooth handling support member 25.

そのため、扱歯支持部材２５の内側に入り込んだ脱穀物へのこなし作用を高める。   Therefore, the action to grind the cereal that has entered the inside of the tooth support member 25 is enhanced.

即ち、脱穀被処理物の塊状に肥大成長を抑制し、未脱粒の穀粒が残ることを防止する。   That is, it suppresses the hypertrophic growth in a lump form of the threshing material, and prevents unthreshed grains from remaining.

遮蔽プレート４５の基部は辺部２８の回転方向の中間部に固定状態に取付け、遮蔽プレート４５の先端は扱歯支持部材２５側に当接または固定状態に取付ける。   The base portion of the shielding plate 45 is fixedly attached to the intermediate portion of the side portion 28 in the rotational direction, and the tip of the shielding plate 45 is attached to the tooth handling support member 25 side in a fixed state.

そのため、前記空間２９は、隣接する二本の扱歯支持部材２５と、扱歯支持部材２５の内側の遮蔽プレート４５と、ドラム部２７の外周とにより包囲された空間として形成され（図４）、空間２９が扱歯支持部材２５の移動軌跡の内側の扱胴２１部分に形成されることになって、その結果、扱室２２の容積を拡大させることができ、脱穀負荷を軽減させることができる。   Therefore, the space 29 is formed as a space surrounded by two adjacent tooth-handling support members 25, a shielding plate 45 inside the tooth-handling support member 25, and the outer periphery of the drum portion 27 (FIG. 4). The space 29 is formed in the treatment barrel 21 part inside the movement locus of the tooth treatment support member 25. As a result, the volume of the treatment chamber 22 can be increased, and the threshing load can be reduced. it can.

また、図９のように、扱歯２０にて持ち回るように回転させられた被処理物Ｓは、遮蔽プレート４５に案内されて、空間２９内に入り、空間２９内にてドラム部２７の頂部３０と辺部２８により撹拌させられ、回転方向上手側の遮蔽プレート４５に至った被処理物は扱胴２１の回転の遠心力により空間２９外に出て、再び、扱歯２０の回転作用を受けて脱穀装置処理を受け、前記空間２９への出入りを反復し、扱室２２の容積を拡大して、脱穀処理効率を向上させられる。   Further, as shown in FIG. 9, the workpiece S rotated so as to be carried around by the tooth-handling 20 is guided by the shielding plate 45 and enters the space 29, and the drum portion 27 of the drum portion 27 in the space 29. The workpiece to be agitated by the top portion 30 and the side portion 28 and reaches the shielding plate 45 on the upper side in the rotational direction comes out of the space 29 due to the centrifugal force of the rotation of the handling cylinder 21, and the rotational action of the tooth handling 20 again. In response, the threshing device process is performed, the entrance and exit to the space 29 is repeated, the volume of the handling chamber 22 is expanded, and the threshing processing efficiency is improved.

また、遮蔽プレート４５の先端を扱歯支持部材２５に固定した場合には、ドラム部２７と扱歯支持部材２５とを遮蔽プレート４５により支持することになるので、互いが互いの強度メンバーとなって、扱胴２１の剛性を向上させられる。   Moreover, when the front-end | tip of the shielding plate 45 is fixed to the tooth handling support member 25, since the drum part 27 and the tooth handling support member 25 will be supported by the shielding plate 45, each becomes a mutual strength member. Thus, the rigidity of the handling cylinder 21 can be improved.

遮蔽プレート４５が扱歯支持部材２５およびドラム部２７と共に回転することにより起風を発生させ、扱室２２からの処理物の漏下を促進させる。   The shield plate 45 rotates together with the tooth support member 25 and the drum portion 27 to generate a wind and promote the leakage of the processed material from the treatment chamber 22.

扱歯支持部材２５のドラム部２７側には、扱歯側遮蔽部材（プレート）４７を設け、扱歯側遮蔽部材４７に遮蔽プレート４５の先端部を当接させる（図４）。   A tooth-handling side shielding member (plate) 47 is provided on the drum portion 27 side of the tooth-handling support member 25, and the tip of the shielding plate 45 is brought into contact with the tooth-handling side shielding member 47 (FIG. 4).

そのため、ドラム部２７に設けた遮蔽プレート４５の剛性を高めて高負荷脱穀時の扱胴２１の破損を防止する。   Therefore, the rigidity of the shielding plate 45 provided in the drum portion 27 is increased to prevent the handling cylinder 21 from being damaged during high-load threshing.

扱歯側遮蔽部材４７は、前記遮蔽プレート４５に、回転方向の下手側から接触させる。   The tooth-handling side shielding member 47 is brought into contact with the shielding plate 45 from the lower side in the rotational direction.

そのため、扱胴２１の回転により、遮蔽プレート４５が受ける被処理物の荷重を扱歯側遮蔽部材４７が支持するので、支持を確実にする。   Therefore, the tooth handling side shielding member 47 supports the load of the object to be processed received by the shielding plate 45 by the rotation of the handling cylinder 21, so that the support is ensured.

また、扱歯側遮蔽部材４７と遮蔽プレート４５との間に異物が詰まるのを防止する。   Further, the foreign matter is prevented from being clogged between the tooth-handling side shielding member 47 and the shielding plate 45.

扱歯側遮蔽部材４７に、扱歯２０の基部を回避するための切欠部４８を形成する（図７）。   A notch 48 for avoiding the base of the tooth-handling 20 is formed in the tooth-handling-side shielding member 47 (FIG. 7).

即ち、扱歯側遮蔽部材４７の扱歯支持部材２５側には、扱歯側遮蔽部材４７の長さ方向に長い切欠部４８を、扱歯２０の取付け間隔に合わせて設ける。   That is, a notch 48 that is long in the length direction of the tooth-handling side shielding member 47 is provided on the tooth-handling support member 25 side of the tooth-handling side shielding member 47 in accordance with the mounting interval of the tooth-handling 20.

そのため、扱歯支持部材２５に扱歯２０を貫通させて固定した場合に、扱歯支持部材２５より内側に扱歯２０の内端が突き出るが、この扱歯２０の内端の突出部分が扱歯側遮蔽部材４７と干渉するのを防止し、組立を容易にする。   Therefore, when the tooth handling 20 is passed through and fixed to the tooth handling support member 25, the inner end of the tooth handling 20 protrudes inside the tooth handling support member 25, but the protruding portion of the inner end of this tooth handling 20 is handled. Interference with the tooth side shielding member 47 is prevented, and assembly is facilitated.

即ち、扱歯支持部材２５に予め扱歯側遮蔽部材４７を固定し、この状態で、扱歯支持部材２５の各取付孔（図示省略）に直棒形状に形成した扱歯２０を夫々挿入すると、扱歯２０の内端が扱歯側遮蔽部材４７の切欠部４８に当接し、この状態で、扱歯２０を扱歯支持部材２５に溶接固定する。   That is, when the tooth-handling side shielding member 47 is fixed to the tooth-handling support member 25 in advance, and the tooth-handling 20 formed in a straight bar shape is inserted into each mounting hole (not shown) of the tooth-handling support member 25 in this state. The inner end of the tooth-handling 20 comes into contact with the notch 48 of the tooth-handling side shielding member 47, and in this state, the tooth-handling 20 is fixed to the tooth-handling support member 25 by welding.

したがって、扱歯側遮蔽部材４７は扱歯２０との干渉を防止するだけでなく、位置決めの作用も奏する。   Therefore, the tooth-handling side shielding member 47 not only prevents interference with the tooth-handling 20 but also has a positioning action.

また、ドラム部２７と扱歯支持部材２５とは、ドラム部２７の各頂点部３０が隣接する扱歯支持部材２５の間に位置させる。   Further, the drum portion 27 and the tooth handling support member 25 are positioned between the tooth handling support members 25 adjacent to each vertex 30 of the drum portion 27.

そして、第二カウンタ軸５４のプーリと回転刃５１のプーリとにベルト５６を掛け回して、回転刃５１を駆動する構成とする。   The belt 56 is wound around the pulley of the second counter shaft 54 and the pulley of the rotary blade 51 to drive the rotary blade 51.

そのため、前側の第一カウンタ軸５３から離れた回転刃５１にベルト伝動する構成であっても、前後中間位置に設けた第二カウンタ軸５４から回転刃５１にベルト伝動するので、各ベルト５５、５６の長さを短くでき、伝動効率を低下させない。   Therefore, even if the belt is transmitted to the rotary blade 51 far from the first counter shaft 53 on the front side, the belt 55 is transmitted to the rotary blade 51 from the second counter shaft 54 provided at the front and rear intermediate positions. The length of 56 can be shortened, and transmission efficiency is not reduced.

また、第二カウンタ軸５４から一番螺旋１５と二番螺旋１６の各プーリにベルト５７を掛け回し、ベルト５７を掛け回して伝動する揺動カウンタプーリ５８から揺動棚１４のプーリにベルト５９を掛け回すことができ、この点でも、各ベルト５７、５９長を短くでき、伝動効率を低下させない。   Further, the belt 57 is wound around the pulleys of the first spiral 15 and the second spiral 16 from the second counter shaft 54, and the belt 59 is moved from the swing counter pulley 58 that is driven by the belt 57 to the pulley of the swing shelf 14. In this respect, the lengths of the belts 57 and 59 can be shortened, and the transmission efficiency is not lowered.
