Description
本發明係關於從稻穀去除稻殼並取出糙米的脫穀殼機，特別有關發揮從稻穀剝下稻殼之作用的一對脫穀殼滾輪之驅動裝置。The present invention relates to a threshing machine for removing rice husks from rice and taking out brown rice, and more particularly to a driving device for a pair of threshing shell rollers which function to peel off rice husks from rice.
脫穀殼機有如下之形式：使一對橡膠滾輪分別向相反方向且彼此的周速不同地旋轉，向上述一對橡膠滾輪間隙供給稻穀，利用滾輪間之周速的差剪切破壞稻殼來進行稻穀脫殼。The husking machine has a form in which a pair of rubber rollers are rotated in opposite directions and at different circumferential speeds, and rice is supplied to the gap between the pair of rubber rollers, and the rice husk is broken by the difference in the peripheral speed between the rollers. To carry out rice shelling.
一對橡膠滾輪係主滾輪和副滾輪；由於主副各滾輪的周速差，橡膠滾輪的磨損在主滾輪及副滾輪各不同(產生偏差)。因此，通常以手動作業進行主副各滾輪的橡膠滾輪替換作業而使磨損的程度相同。該作業可延長主副各滾輪的壽命，使該脫穀殼機經濟性優良。A pair of rubber rollers are the main roller and the secondary roller; the wear of the rubber roller is different between the main roller and the secondary roller due to the difference in the peripheral speed of the rollers of the main and the secondary rollers (a deviation occurs). Therefore, the rubber roller replacement work of the main and auxiliary rollers is usually performed by manual work, and the degree of wear is the same. This operation can extend the life of the main and auxiliary rollers, and the economical performance of the threshing machine is excellent.
然而，由於以手進行主副滾輪的替換作業將使脫穀殼機停止等很麻煩，因此有人提出可省略主副滾輪之替換作業的技術。例如，日本實公昭62-29064號公報、日本特開平3-137945號公報、日本特開2001-38230號公報中所記載的脫穀殼機採用如下之結構：將變速馬達直接連結在主副各滾輪上，使得各個滾輪獨立而旋轉驅動，並且每隔一定時間交互地將高速側切換變更到低速側，將低速側切換變更到高速側。如此一來，由於主副滾輪每隔一定時間就交互地高速、低速旋轉，因此主副滾輪同等地磨損。However, since it is troublesome to stop the unloading of the main and auxiliary rollers by hand, it has been proposed to omit the replacement work of the primary and secondary rollers. For example, the threshing machine described in Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. On the roller, each of the rollers is independently driven to rotate, and the high-speed side switching is alternately changed to the low-speed side at regular intervals, and the low-speed side switching is changed to the high-speed side. In this way, since the primary and secondary rollers alternately rotate at high speed and low speed at regular intervals, the primary and secondary rollers are equally worn.
另一方面，日本特開平3-106452號公報、日本特開2006-312151號公報中所記載的脫穀殼機，以變速齒輪機構或離合器機構切換主副滾輪之轉速。On the other hand, in the threshing machine described in Japanese Laid-Open Patent Publication No. Hei No. 3-106452, the shifting gear mechanism or the clutch mechanism switches the rotational speed of the primary and secondary rollers.
變速齒輪機構使固定在驅動軸上的大小變速齒輪選擇性地與固定在主副各滾輪之旋轉軸上的從動齒輪嚙合。為了使其選擇性地嚙合，必須使固定變速齒輪的驅動軸沿其軸向移動。The shift gear mechanism selectively engages the large-speed shifting gear fixed to the drive shaft with the driven gear fixed to the rotating shaft of each of the main and auxiliary rollers. In order to selectively engage it, it is necessary to move the drive shaft of the fixed shift gear in its axial direction.
離合器機構利用安裝在主副滾輪之旋轉軸上的離合器構件。離合器構件雖然可分別沿旋轉軸的軸方向移動，但在旋轉方向上受限制。另外，在該等離合器構件之兩側具有以傳動帶驅動的大小帶輪，能將離合器構件選擇性地連接到該等帶輪上。離合器構件的移動相對於主副滾輪的旋轉軸同時進行，主滾輪與大帶輪連接時，副滾輪與小帶輪連接，或者反過來連接。該機構仍然須要使離合器構件沿旋轉軸移動。The clutch mechanism utilizes a clutch member that is mounted on a rotating shaft of the primary and secondary rollers. Although the clutch members are respectively movable in the axial direction of the rotating shaft, they are restricted in the rotational direction. Additionally, there are pulleys of different sizes on both sides of the clutch members that are driven by the belt to selectively connect the clutch members to the pulleys. The movement of the clutch member is simultaneously performed with respect to the rotation axis of the main and auxiliary rollers, and when the main roller is coupled to the large pulley, the secondary roller is coupled to the small pulley or vice versa. The mechanism still needs to move the clutch member along the axis of rotation.
依該等裝置，由於即使在稻穀脫殼作業中也從機外操作變速齒輪機構或離合器機構，而使以一次接觸已磨損的高速用橡膠滾輪低速旋轉，未磨損的低速用橡膠滾輪高速旋轉，因此能省略如以往更換滾輪的勞力。According to these devices, even if the shift gear mechanism or the clutch mechanism is operated from outside the machine during the rice husking operation, the high-speed rubber roller that has been worn by one contact is rotated at a low speed, and the non-wearing low-speed rubber roller rotates at a high speed. Therefore, it is possible to omit the labor of replacing the roller as in the past.
然而，在上述日本實公昭62-29064號公報、日本特開平3-137945號公報、日本特開2001-38230號公報中所記載的脫穀殼機，由於在高速側橡膠滾輪以及低速側橡膠滾輪的各旋轉軸上直接連接驅動馬達，因此處於成為過負荷運轉的傾向。亦即，使主副滾輪的間隙確保產生於滾輪間隙及稻穀間之適度的接觸壓力，俾達到所設定之脫殼率(糙米數對投入的稻穀全數)。此時，由於兩個橡膠滾輪為粘彈性體，因此稻穀通過滾輪間隙時，在比滾輪間隙的最狹小部稍微靠跟前處產生最大壓力。在日本實公昭62-29064號公報、日本特開平3-137945號公報、日本特開2001-38230號公報中所記載的脫穀殼機，為克服該壓力，將需要較大的旋轉驅動力。因此，各驅動馬達時常存在以過負荷運轉的問題。對此，日本特開平3-106452號公報、日本特開2006-312151號公報中所記載的脫穀殼機，由於一根無端帶以交叉狀捲繞在高速側橡膠滾輪以及低速側橡膠滾輪之各旋轉軸的帶輪上，因此稻穀通過滾輪間隙時，一對脫穀殼滾輪的回彈力受抑制，具有不須對各驅動馬達施加過大之旋轉驅動力的優點。However, the threshing machine described in the above-mentioned Japanese Patent Publication No. Sho 62-29064, Japanese Laid-Open Patent Publication No. Hei No. Hei No. Hei No. Hei No. Hei No. Hei No. Hei No. 2001-38230, and the high-speed side rubber roller and the low-speed side rubber roller Since the drive motor is directly connected to each of the rotating shafts, it tends to be overloaded. That is, the gap between the primary and secondary rollers is ensured to be generated by the appropriate contact pressure between the roller gap and the rice, and the set shelling rate is reached (the number of brown rice is the total number of rice inputs). At this time, since the two rubber rollers are viscoelastic bodies, when the rice passes through the roller gap, the maximum pressure is generated slightly before the narrowest portion of the gap of the roller. In order to overcome this pressure, a threshing machine described in Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. Therefore, each of the drive motors often has a problem of operating under an overload. In this case, the stripping machine described in Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. 2006-312151 is wound on the high-speed side rubber roller and the low-speed side rubber roller in a cross shape. In the pulley of each of the rotating shafts, when the rice passes through the roller gap, the resilience of the pair of threshing rollers is suppressed, and there is an advantage that it is not necessary to apply an excessive rotational driving force to each of the driving motors.
然而，在日本特開平3-106452號公報、日本特開2006-312151號公報中所記載的脫穀殼機，還產生以下問題。例如，若稻穀的供給量增加，則施加到橡膠滾輪的負荷即橡膠滾輪之旋轉軸的負荷增大，軸因旋轉軸熱膨脹等而變形等。如此一來，將主滾輪及副滾輪的間隙調整成寬廣或狹窄時，使其向旋轉軸方向移動的變速齒輪或離合器構件的動作變差，有切換作業變困難之虞。However, the husking machine described in Japanese Laid-Open Patent Publication No. Hei No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. 2006-312151 discloses the following problems. For example, when the supply amount of the rice is increased, the load applied to the rubber roller, that is, the load on the rotating shaft of the rubber roller is increased, and the shaft is deformed by thermal expansion or the like of the rotating shaft. In this way, when the gap between the main roller and the sub-roller is adjusted to be wide or narrow, the operation of the shift gear or the clutch member that moves in the direction of the rotation axis is deteriorated, and the switching operation becomes difficult.
本發明係關於脫穀殼機之脫穀殼滾輪驅動裝置，本發明的技術課題為：不需要如在旋轉軸上直接連結驅動馬達之脫穀殼機那樣大的旋轉驅動力，即使在主副滾輪的旋轉軸上產生熱膨脹等的變形，也能交互且容易地將主副滾輪的高速旋轉側切換變更到低速旋轉側，並將低速旋轉側切換變更到高速旋轉側。The present invention relates to a threshing shell roller driving device for a threshing machine, and the technical problem of the present invention is that a large rotational driving force such as a grooving machine directly connecting a driving motor on a rotating shaft is not required, even in the main and auxiliary Deformation such as thermal expansion occurs on the rotating shaft of the roller, and the high-speed rotation side switching between the main and auxiliary rollers can be alternately and easily changed to the low-speed rotation side, and the low-speed rotation side switching can be changed to the high-speed rotation side.
本發明之脫穀殼機包含：主副滾輪，相互向內且以不同轉速旋轉；第一驅動系統，將主副滾輪其中之一以高速驅動，將主副滾輪其中之另一以低速驅動；第二驅動系統，將主副滾輪其中之一以低速驅動，將主副滾輪其中之另一以高速驅動；第一、第二帶式離合器機構，切換該等驅動系統並將動力傳遞到主副滾輪；及致動器，驅動帶式離合器機構。The threshing machine of the present invention comprises: main and auxiliary rollers rotating inwardly and at different rotational speeds; the first driving system drives one of the main and auxiliary rollers at a high speed, and the other of the main and auxiliary rollers is driven at a low speed; a second drive system, one of the main and auxiliary rollers is driven at a low speed, and the other of the main and auxiliary rollers is driven at a high speed; the first and second belt clutch mechanisms switch the drive systems and transmit the power to the main and auxiliary a roller; and an actuator that drives the belt clutch mechanism.
主副滾輪係一對脫穀殼滾輪。又，主副滾輪僅係為區別一對滾輪的各滾輪所命名，於滾輪的脫殼性能上並無主副之分。The main and auxiliary rollers are a pair of threshing shell rollers. Moreover, the main and auxiliary rollers are named only for the rollers that distinguish a pair of rollers, and there is no main or sub-division in the shelling performance of the rollers.
主副滾輪的轉動軸中，其中之一轉動軸上軸支安裝有第一大直徑帶輪，其中之另一轉動軸上軸支安裝有第一小直徑帶輪。Among the rotating shafts of the main and auxiliary rollers, one of the rotating shafts is mounted with a first large diameter pulley, and the other rotating shaft has a first small diameter pulley mounted thereon.
第一驅動系統由下列部分構成：該等第一大直徑帶輪、第一小直徑帶輪、第一馬達之驅動帶輪、以及繞掛在該等構件上而連結該等構件的第一無端帶。The first drive system is comprised of: the first large diameter pulley, the first small diameter pulley, the drive pulley of the first motor, and the first endlessly attached to the members to join the members band.
第二驅動系統由下列部分構成：軸支安裝在該其中之一轉動軸上之第二小直徑帶輪、軸支安裝在該其中之另一轉動軸上之第二大直徑帶輪、第二馬達之驅動帶輪、以及繞掛在該等構件上而連結該等構件的第二無端帶。The second drive system is composed of a second small diameter pulley on which the shaft is mounted on one of the rotating shafts, a second large diameter pulley on which the shaft is mounted on the other rotating shaft, and a second A drive pulley for the motor, and a second endless strap that is attached to the members to join the members.
第一帶式離合器機構包含第一臂構件及致動器。The first belt clutch mechanism includes a first arm member and an actuator.
第一臂構件在朝半徑方向伸出的臂前端部，包含張力離合器帶輪。第一臂構件藉由致動器以其中之一轉動軸為中心而轉動。第一臂構件轉動時，往第一驅動系統的第一大直徑帶輪接通或斷開動力。The first arm member includes a tension clutch pulley at an end portion of the arm that projects in the radial direction. The first arm member is rotated by the actuator centered on one of the rotational axes. When the first arm member rotates, the first large diameter pulley of the first drive system is turned on or off.
第二帶式離合器機構係與第一帶式離合器機構同樣，包含第二臂構件及致動器。第二臂構件在朝半徑方向伸出的臂前端部上包含張力離合器帶輪。第二臂構件藉由致動器以其中之另一轉動軸為中心而轉動。第二臂構件轉動時，向第二驅動系統的第二大直徑帶輪接通或斷開動力。The second belt clutch mechanism includes a second arm member and an actuator similarly to the first belt clutch mechanism. The second arm member includes a tension clutch pulley on a front end portion of the arm that protrudes in a radial direction. The second arm member is rotated by the actuator centered on the other of the rotational axes. When the second arm member rotates, the second large diameter pulley of the second drive system is turned on or off.
第一臂構件與第二臂構件藉由致動器同時轉動。The first arm member and the second arm member are simultaneously rotated by the actuator.
第一帶式離合器機構將第一驅動系統的第一無端帶切換為捲繞在第一大直徑帶輪上的位置以及避開捲繞的位置；同時，第二帶式離合器機構將第二驅動系統的第二無端帶切換為避開與第二大直徑帶輪捲繞的位置以及捲繞在該帶輪的位置。The first belt clutch mechanism switches the first endless belt of the first drive system to a position wound on the first large diameter pulley and avoids the winding position; meanwhile, the second belt clutch mechanism drives the second belt The second endless belt of the system is switched to avoid the position with which the second large diameter pulley is wound and the position wound around the pulley.
亦即，第一無端帶捲繞在第一大直徑帶輪上而傳遞動力到第一大直徑帶輪時，第二無端帶避開與第二大直徑帶輪捲繞而不能傳遞動力到第二大直徑帶輪。另一方面，第一無端帶傳遞動力到軸支安裝於其中之一轉動軸上的第一大直徑帶輪時，也傳遞動力到軸支安裝於其中之另一轉動軸上的第一小直徑帶輪。反之，第二無端帶傳遞動力到軸支安裝於其中之另一轉動軸上的第二大直徑帶輪時，也傳遞動力到軸支安裝於其中之一轉動軸上的第二小直徑帶輪。由此，主副滾輪具有速度差並同時旋轉，而且可切換高速旋轉側與低速旋轉側。That is, when the first endless belt is wound on the first large diameter pulley to transmit power to the first large diameter pulley, the second endless belt avoids winding with the second large diameter pulley and cannot transmit power to the first Two large diameter pulleys. On the other hand, when the first endless belt transmits power to the first large diameter pulley to which the shaft is mounted on one of the rotating shafts, the first small diameter is also transmitted to the other rotating shaft on which the shaft is mounted. Pulley. Conversely, when the second endless belt transmits power to the second large diameter pulley on which the shaft is mounted on the other rotating shaft, the second small diameter pulley is also transmitted to the shaft supported on one of the rotating shafts. . Thereby, the main and auxiliary rollers have a speed difference and rotate at the same time, and the high speed rotation side and the low speed rotation side can be switched.
第一臂構件包含：相對於其中之一轉動軸可轉動式安裝的基端部、從該基端部朝第一大直徑帶輪之半徑方向延伸之略呈V字狀的臂部。該V字狀的臂部中，其內角(α)較佳為形成60°。The first arm member includes a base end portion rotatably attached to one of the rotating shafts, and a substantially V-shaped arm portion extending from the base end portion in a radial direction of the first large-diameter pulley. In the V-shaped arm portion, the inner angle (α) is preferably formed at 60°.
第二臂構件亦同，包含：相對於其中之另一轉動軸可轉動式安裝的基端部、從該基端部朝第二大直徑帶輪之半徑方向延伸之略呈V字狀的臂部。該V字狀的臂部中，其內角(α)較佳為形成60°。The second arm member also includes a base portion that is rotatably mounted relative to the other of the rotating shafts, and a slightly V-shaped arm extending from the base end toward the radial direction of the second large diameter pulley. unit. In the V-shaped arm portion, the inner angle (α) is preferably formed at 60°.
致動器能採用使第一臂構件、第二臂構件各別轉動的旋轉式致動器。The actuator can employ a rotary actuator that rotates the first arm member and the second arm member, respectively.
致動器也可由鏈條‧鏈輪傳遞機構所構成。The actuator can also be constructed by a chain ‧ sprocket transmission mechanism.
鏈條‧鏈輪傳遞機構包含：固定在第一臂構件之第一鏈輪、固定在第二臂構件之第二鏈輪、連結第一及第二鏈輪之雙鏈輪、以及桿式致動器。另外，在第一鏈輪與雙鏈輪間、以及第二鏈輪與雙鏈輪間可各別繞掛有鏈條。雙鏈輪形成藉由桿式致動器而旋轉約90°的配置。The chain sprocket transmission mechanism includes: a first sprocket fixed to the first arm member, a second sprocket fixed to the second arm member, a double sprocket connecting the first and second sprocket, and a lever actuation Device. In addition, a chain may be wound between the first sprocket and the double sprocket, and between the second sprocket and the double sprocket. The double sprocket is formed in a configuration rotated by about 90° by a lever actuator.
當雙鏈輪旋轉時，第一、第二臂構件同步轉動。另外，該第一驅動系統之無端帶位於捲繞該第一大直徑帶輪而能傳遞動力的位置上時，該第二驅動系統之無端帶位於避開捲繞該第二大直徑帶輪的位置；該第二驅動系統之無端帶位於捲繞該第二大直徑帶輪而能傳遞動力的位置上時，該第一驅動系統之無端帶位於避開捲繞該第一大直徑帶輪的位置。When the double sprocket rotates, the first and second arm members rotate synchronously. In addition, when the endless belt of the first driving system is located at a position where the first large diameter pulley is wound to transmit power, the endless belt of the second driving system is located to avoid winding the second large diameter pulley. a position where the endless belt of the second drive system is located at a position where the second large diameter pulley is wound to transmit power, the endless belt of the first drive system is located to avoid winding the first large diameter pulley position.
第一驅動系統內設置利用氣缸的伸縮進行上述無端帶之拉緊．鬆弛的第一惰輪(idler pulley)；第二驅動系統內設置利用氣缸的伸縮進行上述無端帶之拉緊．鬆弛的第二惰輪與第三惰輪。The first drive system is provided with the expansion and contraction of the above-mentioned endless belt by the expansion and contraction of the cylinder. a slack first idler pulley; the second drive system is provided with the expansion and contraction of the above-mentioned endless belt by the expansion and contraction of the cylinder. a loose second idler and a third idler.
如上所述，本發明採用在以往主副滾輪之旋轉軸方向上使離合器改變為前後移動的結構，而使第一臂構件與第二臂構件轉動並切換第一驅動系統及第二驅動系統之作動的結構。因此，即使產生旋轉軸之熱膨脹等變形，交互地將高速側切換到低速側、將低速側切換到高速側的變更操作也能容易地進行。又，本發明由於未使用朝旋轉軸方向滑動之稱為離合器構件的每次動作易產生衝擊或磨損的零件，因此無論重複進行多少次帶式離合器機構與惰輪的切換操作，皆耐久性優良。As described above, the present invention adopts a configuration in which the clutch is changed to the forward and backward movement in the direction of the rotation axis of the conventional primary and secondary rollers, and the first arm member and the second arm member are rotated and the first drive system and the second drive system are switched. Actuated structure. Therefore, even if deformation such as thermal expansion of the rotating shaft occurs, the changing operation of switching the high speed side to the low speed side and the low speed side to the high speed side can be easily performed. Further, since the present invention does not use a member which is likely to be impacted or worn every time the clutch member slides in the direction of the rotation axis, it is excellent in durability regardless of how many times the switching operation of the belt clutch mechanism and the idle gear is repeated. .
第一、第二臂構件的臂部中，使內角(α)形成約60°而略呈V字狀時，安裝在第一、第二臂構件之各臂前端部上的一對張力離合器帶輪的間隔變得稍微較寬。因此，例如於解除第一大直徑帶輪及第二大直徑帶輪之動力傳遞的狀態下，即使該等帶輪的外徑約220mm大，也能確實防止第一、第二無端帶不小心往該等帶輪捲繞並成為傳遞動力的狀態，而可靠地進行動力的“接通”“斷開”動作。In the arm portions of the first and second arm members, when the inner angle (α) is formed to be approximately 60° and slightly V-shaped, a pair of tension clutches are attached to the front end portions of the arms of the first and second arm members. The spacing of the pulleys becomes slightly wider. Therefore, for example, in a state in which the power transmission of the first large diameter pulley and the second large diameter pulley is released, even if the outer diameter of the pulleys is about 220 mm, the first and second endless belts can be surely prevented from being careless. When the pulleys are wound and the power is transmitted, the "on" and "off" operations of the power are reliably performed.
以旋轉式致動器使第一、第二臂構件轉動時，由於旋轉式致動器為高扭矩，且能使臂部的旋轉角變大，因此能更加確實進行動力的“接通”“斷開”動作。When the first and second arm members are rotated by the rotary actuator, since the rotary actuator has a high torque and the rotation angle of the arm portion can be increased, it is possible to more reliably perform the "on" of the power. Disconnect" action.
為使第一、第二臂構件轉動而採用桿式氣缸與鏈條‧鏈輪傳遞機構時，能藉由一個氣缸簡單地使第一驅動系統及第二驅動系統的帶式離合器機構的作動同步。又，相較於使用複數個旋轉式致動器的情況，不需要用以使第一、第二驅動系統同步的電磁閥與邏輯繼電器等，結構簡單，能抑制製造成本。When the rod type cylinder and the chain sprocket transmission mechanism are used to rotate the first and second arm members, the operation of the belt clutch mechanism of the first drive system and the second drive system can be easily synchronized by one cylinder. Further, compared with the case of using a plurality of rotary actuators, a solenoid valve and a logic relay for synchronizing the first and second drive systems are not required, and the structure is simple, and the manufacturing cost can be suppressed.
由於第一驅動系統內之第一惰輪、第二驅動系統內之第二惰輪與第三惰輪各別利用氣缸的伸縮進行第一、第二無端帶的拉緊．鬆弛，因此僅使氣缸伸縮就能簡單地各別進行第一、第二無端帶的拉緊．鬆弛，甚至能各別利用第一、第二帶式離合器機構簡單地進行往第一、第二大直徑帶輪傳遞之動力“接通”“斷開”動作。Since the first idler in the first drive system, the second idler and the third idler in the second drive system respectively use the expansion and contraction of the cylinder to perform tensioning of the first and second endless belts. Relaxation, so that only the cylinder can be stretched and stretched, and the first and second endless belts can be tensioned separately. The slack can even be used to simply perform the "on" and "off" actions of the power transmitted to the first and second large diameter pulleys by the first and second belt clutch mechanisms.

而且，在該第一驅動系統內的第一大直徑帶輪9設有包含略呈V字狀之臂部的第一臂構件16。該臂部從第一大直徑帶輪9的中心朝半徑方向延伸，前端以其中之一轉動軸5為中心，並以在第一大直徑帶輪9的外周上描畫轉動軌跡的方式轉動。當藉由操作而使該第一臂構件16轉動時，第一無端帶13往第一大直徑帶輪9的動力將被接通或斷開。亦即，以第一臂構件16與第一無端帶13構成第一帶式離合器機構15。符號14a、14b係安裝在該第一臂構件16之前端的一對張力離合器帶輪。又，關於圖1以及圖2所示的第一帶式離合器機構15的實線位置，由於係使第一無端帶13捲繞在大直徑帶輪9而傳遞動力的位置，因此處於動力“接通”的狀態。Further, the first large diameter pulley 9 in the first drive system is provided with a first arm member 16 including a slightly V-shaped arm portion. The arm portion extends in the radial direction from the center of the first large-diameter pulley 9, and the front end is centered on one of the rotating shafts 5, and is rotated in such a manner as to trace the rotational path on the outer circumference of the first large-diameter pulley 9. When the first arm member 16 is rotated by the operation, the power of the first endless belt 13 to the first large diameter pulley 9 will be turned on or off. That is, the first arm member 16 and the first endless belt 13 constitute the first band clutch mechanism 15. Symbols 14a, 14b are a pair of tension clutch pulleys attached to the front end of the first arm member 16. Further, with respect to the solid line position of the first belt clutch mechanism 15 shown in Figs. 1 and 2, since the first endless belt 13 is wound around the large diameter pulley 9 to transmit power, the power is "connected". The state of the pass.
第一驅動系統具備第一惰輪12。第一惰輪12藉由氣缸17之可動軸的伸縮，以支點12b為中心可一直轉動到一點鏈線的位置(符號12a)。The first drive system is provided with a first idler gear 12. The first idler pulley 12 is rotated by the expansion and contraction of the movable shaft of the cylinder 17 so as to be always rotated to the position of the one-point chain line (symbol 12a) around the fulcrum 12b.
第一驅動系統的第一帶式離合器機構15藉由圖3所示的旋轉式致動器30a，而以其中之一轉動軸5為中心可一直轉動到一點鏈線的位置。一點鏈線位於第一無端帶13從捲繞在第一大直徑帶輪9處避開的位置，係動力“斷開”的狀態。The first belt clutch mechanism 15 of the first drive system is rotated by the rotary actuator 30a shown in FIG. 3 to the position of one of the chain lines with one of the rotating shafts 5 as a center. The one-point chain line is in a state where the first endless belt 13 is shunned from the first large-diameter pulley 9, and the power is "disconnected".
在上述其中之一轉動軸5以及其中之另一轉動軸6，在接近第一大直徑帶輪9的軸方向內側固定有第二小直徑帶輪19，在接近上述第一小直徑帶輪10的軸方向的內側固定有第二大直徑帶輪20。另外，將第二無端帶24繞掛在第二小直徑帶輪19、第二大直徑帶輪20、第二驅動馬達8的驅動帶輪21、設在該機架2下部的第二惰輪22以及第三惰輪23上，而相互連接。由第二無端帶24及該等帶輪20~23構成第二驅動系統。In one of the above-described rotating shafts 5 and the other of the rotating shafts 6, a second small-diameter pulley 19 is fixed to the inner side in the axial direction of the first large-diameter pulley 9, near the first small-diameter pulley 10 The second large diameter pulley 20 is fixed to the inner side in the axial direction. In addition, the second endless belt 24 is wound around the second small diameter pulley 19, the second large diameter pulley 20, the drive pulley 21 of the second drive motor 8, and the second idler provided at the lower portion of the frame 2. 22 and the third idler 23 are connected to each other. The second endless belt 24 and the pulleys 20-23 constitute a second drive system.
第二驅動系統的第二無端帶24以帶的腹面繞掛在第二小直徑帶輪19，並且用帶的背面以斜掛方式繞掛在第二大直徑帶輪20，以使第二小直徑帶輪19及第二大直徑帶輪20相互向內旋轉。圖1中，第二無端帶24呈順時針方向旋轉而構成。The second endless belt 24 of the second drive system is wound around the second small diameter pulley 19 with the ventral surface of the belt, and is hung around the second large diameter pulley 20 with the back side of the belt to make the second small The diameter pulley 19 and the second large diameter pulley 20 rotate inwardly from each other. In Fig. 1, the second endless belt 24 is configured to rotate in a clockwise direction.
而且，該第二驅動系統內的第二大直徑帶輪20，設有略呈V字狀的第二臂構件27；該V字狀的第二臂構件27以其中之另一轉動軸6為中心，而臂部之前端在第二大直徑帶輪20的外周上描畫轉動軌跡的方式轉動。以該第二臂構件27與第二無端帶24構成第二帶式離合器機構26。亦即，當該第二臂構件27按操作者的指示轉動時，往上述第二大直徑帶輪20的動力傳遞將被“接通”或“斷開”。符號25a、25b是安裝在第二臂構件27之臂部前端的一對張力離合器帶輪。又，圖1及圖2所示的第二帶式離合器機構26的實線位置係往第二大直徑帶輪20的動力傳遞為“斷開”的狀態。Moreover, the second large diameter pulley 20 in the second drive system is provided with a second V-shaped second arm member 27; the V-shaped second arm member 27 is formed by the other rotating shaft 6 The center is rotated while the front end of the arm is drawn on the outer circumference of the second large diameter pulley 20. The second arm member 27 and the second endless belt 24 constitute a second belt clutch mechanism 26. That is, when the second arm member 27 is rotated as instructed by the operator, the power transmission to the second large diameter pulley 20 will be "on" or "off". Reference numerals 25a and 25b are a pair of tension clutch pulleys attached to the front end of the arm portion of the second arm member 27. Further, the solid line position of the second belt clutch mechanism 26 shown in FIGS. 1 and 2 is a state in which the power transmission to the second large diameter pulley 20 is "OFF".
第二驅動系統的第二惰輪22藉由氣缸28之可動軸的伸縮，以支點22b為中心可一直轉動到一點鏈線的位置(符號22a)。又，第三惰輪23藉由氣缸29之可動軸的伸縮，以支點為中心可一直轉動到一點鏈線的位置(符號23a)。另外，第二驅動系統的第二帶式離合器機構26形成藉由氣缸(未圖示)或圖3所示之旋轉式致動器30b，而以其中之另一轉動軸6為中心可一直轉動到一點鏈線的位置的結構。一點鏈線的位置係往第二大直徑帶輪20的動力傳遞為“接通”的狀態。The second idler gear 22 of the second drive system is rotated by the expansion and contraction of the movable shaft of the cylinder 28 to the position of the one-point chain line (symbol 22a) around the fulcrum 22b. Further, the third idle gear 23 is rotated by the expansion and contraction of the movable shaft of the cylinder 29 so as to be always rotated to the position of the one-point chain line (symbol 23a) around the fulcrum. In addition, the second belt clutch mechanism 26 of the second drive system is formed by a cylinder (not shown) or the rotary actuator 30b shown in FIG. 3, and is rotatable about the other of the rotation shafts 6 The structure to the position of a little chain line. The position of the one-point chain line is a state in which the power transmission to the second large-diameter pulley 20 is "on".
圖3顯示上述之第一驅動系統中的第一帶式離合器機構15的詳細構造。主滾輪3之其中之一轉動軸5固定有第一小直徑帶輪10以及第一大直徑帶輪9，並設有略呈V字狀的第一臂構件16俾於夾住第一大直徑帶輪9之輪轂部端面間9a、9a。第一大直徑帶輪9的外徑約為220mm，第一小直徑帶輪10的外徑約為160mm。上述第一臂構件16中，其基端部16a藉由軸承16d相對於其中之一轉動軸5以可自由轉動式受樞支。從其基端部16a沿第一大直徑帶輪9的半徑形成朝外周方向延伸之略呈V字狀的臂部16b。臂部16b、16b間，其內角(α)約60°。另外，第一臂構件16的前端部16c、16c上各裝有以旋轉自如的張力離合器帶輪14a、14b。如此一來，即使第一大直徑帶輪9為外徑約220mm的大直徑帶輪，第一無端帶13也能藉由第一帶式離合器機構15確實地切換為捲繞到第一大直徑帶輪9之狀態以及避開該捲繞之狀態，從而確實地進行動力對於第一大直徑帶輪9間的“接通”(傳遞)、“斷開”(非傳遞)。Figure 3 shows the detailed construction of the first belt clutch mechanism 15 in the first drive system described above. One of the main rollers 3 is fixed with a first small-diameter pulley 10 and a first large-diameter pulley 9 and a first V-shaped first arm member 16 for clamping the first large diameter. The end portions 9a and 9a of the hub portion of the pulley 9 are provided. The outer diameter of the first large diameter pulley 9 is about 220 mm, and the outer diameter of the first small diameter pulley 10 is about 160 mm. In the first arm member 16, the base end portion 16a is pivotally supported by the bearing 16d with respect to one of the rotating shafts 5 so as to be freely rotatable. A substantially V-shaped arm portion 16b extending in the outer circumferential direction is formed from the base end portion 16a along the radius of the first large-diameter pulley 9. The inner angle (α) between the arms 16b and 16b is about 60°. Further, the front end portions 16c and 16c of the first arm member 16 are each provided with oscillating tension clutch pulleys 14a and 14b. In this way, even if the first large diameter pulley 9 is a large diameter pulley having an outer diameter of about 220 mm, the first endless belt 13 can be surely switched to be wound to the first large diameter by the first belt clutch mechanism 15. The state of the pulley 9 and the state of avoiding the winding make sure that the power is "on" (transmitted) and "disconnected" (not transmitted) between the first large-diameter pulleys 9.
而且，在第一臂構件16藉由固定件34裝有旋轉式致動器30。由於內部的葉輪(葉片)藉由從空氣配管31供給的空氣壓而滑動，因此旋轉式致動器30以其中之一轉動軸5為中心使第一臂構件16朝圓周方向轉動。該旋轉式致動器30可使用例如小金井股份有限公司(KOGANEI CORPORATION)製造之型號為RAK300等的市售產品。Moreover, the rotary actuator 30 is mounted on the first arm member 16 by the fixing member 34. Since the inner impeller (blade) slides by the air pressure supplied from the air pipe 31, the rotary actuator 30 rotates the first arm member 16 in the circumferential direction around one of the rotating shafts 5. The rotary actuator 30 can use, for example, a commercially available product of the model RAK300 manufactured by KOGANEI CORPORATION.
在第二驅動系統的第二帶式離合器機構26中，亦僅第二臂構件27的安裝方向不同，結構與圖3相同。In the second belt clutch mechanism 26 of the second drive system, only the second arm member 27 is mounted in the same direction, and the configuration is the same as that of FIG.
又，圖1及圖2所示的符號32係設置在機架2上部之用以供應穀物的供給口；機架2內，在供給口32之正下方加裝有振動供料器、供給穀物到主副滾輪3、4間的滑槽。振動供料器的穀物流量可加以調整。Further, the reference numerals 32 shown in Figs. 1 and 2 are provided at the upper portion of the frame 2 for supplying the grain supply port; in the frame 2, a vibration feeder is provided directly below the supply port 32 to supply the grain. To the chute between the main and auxiliary rollers 3, 4. The grain flow of the vibrating feeder can be adjusted.
符號33係設置在機架2側部的空壓控制裝置。空壓控制裝置33將從壓縮機(未圖示)等空氣供給源所供應的高壓空氣輸送到各氣缸17、28、29以及旋轉式致動器30等。因此，在空壓控制裝置33加裝有電磁閥、邏輯繼電器、自動斷路器、端子板等(均未圖示)。又，符號18係為達到所設定之脫殼率而調節滾輪間隙的滾輪間隙調節裝置。Reference numeral 33 is a pneumatic control device provided at the side of the frame 2. The air pressure control device 33 supplies high-pressure air supplied from an air supply source such as a compressor (not shown) to each of the cylinders 17, 28, 29, the rotary actuator 30, and the like. Therefore, a solenoid valve, a logic relay, an automatic circuit breaker, a terminal block, and the like are attached to the air pressure control device 33 (none of which is shown). Further, reference numeral 18 is a roller gap adjusting device that adjusts the gap of the roller to the set casing rate.
以下，參照圖4A、4B對本發明之脫穀殼滾輪驅動裝置的動作步驟進行說明。Hereinafter, an operation procedure of the threshing shell roller driving device of the present invention will be described with reference to Figs. 4A and 4B.
假定脫穀殼機1上裝有新品的主副滾輪3、4(橡膠滾輪)。操作者調節第一帶式離合器機構15的位置，並操作第一惰輪12使第一無端帶13拉緊。於是，脫殼作業藉由第一驅動系統而處於可啟動的狀態。It is assumed that the stripper 1 is equipped with new main and auxiliary rollers 3, 4 (rubber rollers). The operator adjusts the position of the first belt clutch mechanism 15 and operates the first idler pulley 12 to tension the first endless belt 13. Thus, the husking operation is in a bootable state by the first drive system.
亦即，控制第一般旋轉式致動器30a而轉動第一臂構件16，使張力離合器帶輪14a、14b處於圖4A的實線位置。因此，第一無端帶13向第一大直徑帶輪9傳遞動力，第一帶式離合器機構15往第一大直徑帶輪9的動力傳遞狀態成為“接通”狀態。接著，氣缸17的可動軸伸張，第一惰輪12移動到圖4A的實線位置。於是，第一無端帶13被拉緊，可從第一無端帶13向第一大直徑帶輪9傳遞動力。That is, the first rotary actuator 30a is controlled to rotate the first arm member 16, so that the tension clutch pulleys 14a, 14b are in the solid line position of FIG. 4A. Therefore, the first endless belt 13 transmits power to the first large diameter pulley 9, and the power transmission state of the first belt clutch mechanism 15 to the first large diameter pulley 9 is "on". Next, the movable shaft of the cylinder 17 is stretched, and the first idler gear 12 is moved to the solid line position of Fig. 4A. Thus, the first endless belt 13 is tensioned, and power can be transmitted from the first endless belt 13 to the first large diameter pulley 9.
另一方面，不使第二帶式離合器機構26作動，第二無端帶24往第二大直徑帶輪20的動力傳遞仍然維持“斷開”狀態。On the other hand, without the second belt clutch mechanism 26 being actuated, the power transmission of the second endless belt 24 to the second large diameter pulley 20 remains in the "OFF" state.
在此狀態下，對脫穀殼機1接通電源，開始驅動第一驅動馬達7。使第二驅動馬達8先停止。In this state, the stripper 1 is powered on, and the first drive motor 7 is started to be driven. The second drive motor 8 is first stopped.
第一驅動馬達7的驅動力藉由第一驅動系統的第一無端帶13往第一大直徑帶輪9以及第一小直徑帶輪10傳遞，主滾輪3以低轉速旋轉的同時，副滾輪4以高轉速旋轉，且相互向內旋轉。The driving force of the first driving motor 7 is transmitted to the first large diameter pulley 9 and the first small diameter pulley 10 by the first endless belt 13 of the first driving system, and the primary roller 3 rotates at a low rotation speed while the secondary roller 4 Rotate at high speed and rotate inward toward each other.
另外，從供給口32所供給的穀物因主副滾輪3、4的周速差及其按壓力受到脫殼作用。Further, the grain supplied from the supply port 32 is subjected to the husking action due to the difference in the peripheral speed of the primary and secondary rollers 3, 4 and the pressing force thereof.
如上述，使第一驅動系統處於驅動狀態而持續進行脫殼作業時，主副滾輪3、4會磨損。以高轉速旋轉的副滾輪4相較於以低轉速旋轉的主滾輪3，由於接觸稻穀的面積總和較多，因此比主滾輪3更早地磨損。其結果，副滾輪4的外徑變小，主副滾輪3、4間的周速差減少。在此，例如周速差低於既定值1%時，進行將驅動機構從第一驅動系統切換到第二驅動系統的操作。As described above, when the first drive system is in the driving state and the husking operation is continued, the primary and secondary rollers 3, 4 are worn. The sub-roller 4 that rotates at a high rotation speed wears earlier than the main roller 3 because the main roller 3 that rotates at a low rotation speed has a larger total area of contact with the rice. As a result, the outer diameter of the secondary roller 4 is reduced, and the circumferential speed difference between the primary and secondary rollers 3 and 4 is reduced. Here, for example, when the circumferential speed difference is lower than a predetermined value of 1%, an operation of switching the drive mechanism from the first drive system to the second drive system is performed.
從第一驅動系統切換到第二驅動系統時，首先使第一驅動馬達7的驅動停止，接著操作氣缸17而使第一惰輪12轉動到上方，並使第一無端帶13鬆弛。再來，控制旋轉式致動器30a而轉動第一臂構件16，使第一帶式離合器機構15的張力離合器帶輪14a、14b處於圖4B所示的虛線位置。此時之第一臂構件16的旋轉呈逆時針轉動，約為175°。亦即，第一帶式離合器機構15中，第一無端帶13往第一大直徑帶輪9的動力傳遞處於“斷開”狀態。When switching from the first drive system to the second drive system, the driving of the first drive motor 7 is first stopped, then the cylinder 17 is operated to rotate the first idler gear 12 upward, and the first endless belt 13 is slackened. Then, the rotary actuator 30a is controlled to rotate the first arm member 16, so that the tension clutch pulleys 14a, 14b of the first band clutch mechanism 15 are at the broken line position shown in Fig. 4B. At this time, the rotation of the first arm member 16 is counterclockwise, which is about 175°. That is, in the first belt clutch mechanism 15, the power transmission of the first endless belt 13 to the first large diameter pulley 9 is in an "off" state.
而且，第二驅動系統藉由第二帶式離合器機構26、第二惰輪22以及第三惰輪23而起動。亦即，控制第二旋轉式致動器30b，並轉動第二臂構件27。藉由該轉動，臂部16b前端的張力離合器帶輪25a、25b處於圖4B的實線位置。此時，於圖中，第二臂構件27呈逆時針轉動而約175°。其結果，藉由第二帶式離合器機構26，從第二無端帶24往第二大直徑帶輪20的動力傳遞功能成為“接通”狀態。接著，氣缸28、29的可動軸伸張，而第二惰輪22及第三惰輪23移動到圖4B的實線位置，第二無端帶24被拉緊。Moreover, the second drive system is activated by the second belt clutch mechanism 26, the second idler gear 22, and the third idler gear 23. That is, the second rotary actuator 30b is controlled and the second arm member 27 is rotated. By this rotation, the tension clutch pulleys 25a, 25b at the front end of the arm portion 16b are in the solid line position of Fig. 4B. At this time, in the figure, the second arm member 27 is rotated counterclockwise by about 175°. As a result, the power transmission function from the second endless belt 24 to the second large diameter pulley 20 is "on" by the second belt clutch mechanism 26. Then, the movable shafts of the cylinders 28, 29 are stretched, and the second idler gear 22 and the third idler gear 23 are moved to the solid line position of Fig. 4B, and the second endless belt 24 is tensioned.
於此狀態下，驅動第二驅動馬達8(第一驅動馬達7停止)時，第二驅動馬達8的驅動力經由第二驅動系統的第二無端帶24往第二大直徑帶輪20及第二小直徑帶輪19傳遞；且與上述相反地，主滾輪3以高轉速旋轉之同時，副滾輪4以低轉速旋轉，並相互向內旋轉。In this state, when the second drive motor 8 is driven (the first drive motor 7 is stopped), the driving force of the second drive motor 8 is transmitted to the second large-diameter pulley 20 via the second endless belt 24 of the second drive system. The two small-diameter pulleys 19 are transmitted; and contrary to the above, while the main rollers 3 are rotated at a high rotational speed, the secondary rollers 4 rotate at a low rotational speed and rotate inwardly toward each other.
如上所述，藉由切換第一、第二驅動馬達7、8，第一、第二帶式離合器機構15、26以及第一~第三惰輪12、22、23的作動，持續進行脫殼作業。As described above, by switching the first and second drive motors 7, 8, the first and second belt clutch mechanisms 15, 26 and the first to third idlers 12, 22, 23, the husking continues. operation.
於此實施例中，未使用如以往在脫穀殼滾輪的旋轉軸方向滑動之構造的離合器。因此，即使產生旋轉軸的熱膨脹等變形，也能容易確實地進行將高旋轉側滾輪往低旋轉側滾輪、或者將低旋轉側滾輪往高旋轉側滾輪交互切換的操作。又，該實施例由於未使用朝旋轉軸方向滑動之稱離合器構件之每次作動都易產生衝擊或磨損的零件，故耐久性優良。而且，由於並非如以往在脫穀殼滾輪的旋轉軸上直接連結驅動馬達的結構，因此也不需要較大的旋轉驅動力。In this embodiment, a clutch having a structure that slides in the direction of the rotation axis of the threshing roller is not used. Therefore, even if deformation such as thermal expansion of the rotating shaft occurs, it is possible to easily perform an operation of alternately switching the high-rotation side roller to the low-rotation side roller or the low-rotation side roller to the high-rotation side roller. Moreover, this embodiment is excellent in durability because it is easy to generate impact or wear due to the fact that the clutch member that slides in the direction of the rotation axis is not used. Further, since the drive motor is not directly coupled to the rotating shaft of the threshing shell roller as in the related art, a large rotational driving force is not required.
其次，關於使第一、第二臂構件16、27轉動的致動器，說明另外之實施例，並參照圖5以及圖6說明之。Next, another embodiment will be described with respect to an actuator for rotating the first and second arm members 16, 27, and will be described with reference to Figs. 5 and 6 .

The second arm member 27 of the belt clutch mechanism 26 of the second drive system is fixed to the base end portion 27a by a bolt, a nut or the like (not shown). Further, under the first sprocket 50, a relay double sprocket 53 is rotatably mounted on a rotating shaft 52 pivotally mounted on the frame 2. Further, under the second sprocket 51, a synchronizing double sprocket 55 is rotatably mounted on a rotating shaft 54 pivotally mounted to the frame 2. Further, a plurality of tension sprocket wheels 56, 57 are provided on the frame 2 at appropriate positions corresponding to the above-described double sprocket wheels 53, 55.
第一鏈輪50、第二鏈輪51以及中繼用雙鏈輪53，直徑為116mm，其齒數為27；另一方面，雙鏈輪55，直徑為226mm，其齒數為54，形成速度比為1：2。亦即，雙鏈輪55係用以使第一鏈輪50及第二鏈輪51的旋轉同步的構件，當使同步用雙鏈輪55以旋轉角轉動約90°時，第一鏈輪50、第二鏈輪51以及中繼用雙鏈輪53將成為以旋轉角轉動約180°的設定。The first sprocket 50, the second sprocket 51, and the relay double sprocket 53 have a diameter of 116 mm and a number of teeth of 27; on the other hand, the double sprocket 55 has a diameter of 226 mm and a number of teeth of 54, forming a speed ratio. It is 1:2. That is, the double sprocket 55 is a member for synchronizing the rotations of the first sprocket 50 and the second sprocket 51, and the first sprocket 50 is rotated when the synchronization double sprocket 55 is rotated by about 90° at a rotation angle. The second sprocket 51 and the relay double sprocket 53 are set to rotate by about 180° at a rotation angle.
在同步用雙鏈輪55的一側鏈輪55a、中繼用雙鏈輪53的一側鏈輪53a以及張力用鏈輪57之間繞掛有第一鏈條58；同樣地，在同步用雙鏈輪55的另一側鏈輪55b、第二鏈輪51以及張力用鏈輪56之間繞掛有第二鏈條59。在中繼用雙鏈輪53的另一側鏈輪53b以及第一鏈輪50之間繞掛有傳遞速度比1：1之動力的傳動鏈條60。The first chain 58 is wound between the one side sprocket 55a of the synchronizing double sprocket 55, the one side sprocket 53a of the relay double sprocket 53 and the tension sprocket 57. Similarly, the double pair for synchronization A second chain 59 is wound between the other side sprocket 55b of the sprocket 55, the second sprocket 51, and the tension sprocket 56. A transmission chain 60 that transmits power at a speed ratio of 1:1 is wound between the other side sprocket 53b of the relay double sprocket 53 and the first sprocket 50.
同步用雙鏈輪55以桿式氣缸61轉動。該桿式氣缸61係使可動桿在直線上伸縮的構件，可作為致動器使用。The synchronizing double sprocket 55 is rotated by the rod cylinder 61. The rod type cylinder 61 is a member that expands and contracts the movable rod in a straight line, and can be used as an actuator.
桿式氣缸61中，氣缸部61a隔著台座62而固定在機架2上，可動桿部61b的前端部61c透過樞支銷63而樞支安裝在同步用雙鏈輪55。因此，當可動桿部61b進退時，同步用雙鏈輪55轉動。例如，可動桿部61b的衝程約為100mm時，可使同步用雙鏈輪55轉動約90°。In the rod type cylinder 61, the cylinder portion 61a is fixed to the frame 2 via the pedestal 62, and the front end portion 61c of the movable lever portion 61b is pivotally supported by the synchronizing double sprocket 55 via the pivot pin 63. Therefore, when the movable lever portion 61b advances and retracts, the synchronizing double sprocket 55 rotates. For example, when the stroke of the movable lever portion 61b is about 100 mm, the synchronizing double sprocket 55 can be rotated by about 90 degrees.
參照圖4、圖5及圖6，針對上述鏈條‧鏈輪傳遞機構說明其作用。The action of the chain ‧ sprocket transmission mechanism will be described with reference to Figs. 4, 5 and 6.
假定在脫穀殼機上裝有新品之主副滾輪3、4的狀態。藉由第一驅動系統使脫殼作業起動。同時進行第一、第二帶式離合器機構15、26的位置調節。亦即，當使桿式氣缸61的可動桿部61b伸長(請參照圖5)時，同步用雙鏈輪55呈順時針方向轉動約90°。隨之，第一驅動系統中，透過第一鏈條58及傳動鏈條60，中繼用雙鏈輪53、第一鏈輪50及第一臂構件16的基端部16a呈順時針方向轉動約180°。於是，張力離合器帶輪14a、14b移動到第一無端帶13捲繞在第一大直徑帶輪9上的位置。此狀態下，往第一大直徑帶輪9的動力傳遞為“接通”。It is assumed that the state of the main sub-rollers 3, 4 of the new product is mounted on the threshing machine. The husking operation is started by the first drive system. The position adjustment of the first and second belt clutch mechanisms 15, 26 is simultaneously performed. That is, when the movable lever portion 61b of the rod type cylinder 61 is extended (refer to FIG. 5), the synchronizing double sprocket 55 is rotated clockwise by about 90 degrees. Accordingly, in the first drive system, the base chain end portion 16a of the relay double sprocket 53, the first sprocket 50 and the first arm member 16 is rotated clockwise by about 180 through the first chain 58 and the drive chain 60. °. Thus, the tension clutch pulleys 14a, 14b are moved to a position where the first endless belt 13 is wound around the first large diameter pulley 9. In this state, the power transmission to the first large diameter pulley 9 is "on".
另一方面，第二驅動系統中，第二臂構件27的基端部27a透過第二鏈條59呈順時針方向轉動約180°。於是，臂部16b前端的張力離合器帶輪25a、25b移動到避開第二無端帶24捲繞在第二大直徑帶輪20上的位置。此狀態下，往第二大直徑帶輪20的動力傳遞為“斷開”(圖4A、圖1的狀態)。On the other hand, in the second drive system, the base end portion 27a of the second arm member 27 is rotated by about 180 in the clockwise direction through the second chain 59. Then, the tension clutch pulleys 25a, 25b at the front end of the arm portion 16b are moved to a position where the second endless belt 24 is wound around the second large diameter pulley 20. In this state, the power transmission to the second large diameter pulley 20 is "OFF" (the state of FIG. 4A, FIG. 1).
於該狀態下，當對脫穀殼機1接通電源，開始驅動第一驅動馬達7(第二驅動馬達8停止)時，第一驅動馬達7的驅動力經由第一驅動系統的第一無端帶13而往第一大直徑帶輪9及第一小直徑帶輪10傳遞；主滾輪3以低轉速旋轉之同時，副滾輪4以高轉速旋轉，且相互向內旋轉。另外，從供給口32所供應的穀物因主副滾輪3、4的周速差及其按壓力受到脫殼作用。In this state, when the power supply to the threshing machine 1 is started and the first drive motor 7 is started to be driven (the second drive motor 8 is stopped), the driving force of the first drive motor 7 is via the first end of the first drive system. The belt 13 is transferred to the first large diameter pulley 9 and the first small diameter pulley 10; while the main roller 3 is rotated at a low rotation speed, the secondary roller 4 rotates at a high rotation speed and rotates inwardly toward each other. Further, the grain supplied from the supply port 32 is subjected to the shelling action due to the circumferential speed difference of the main and auxiliary rollers 3, 4 and its pressing force.
如上述，當使第一驅動系統處於驅動狀態持續進行脫殼作業時，與上述同樣地，由於主副滾輪3、4會磨損，因此進行將驅動機構從第一驅動系統切換到第二驅動系統的操作。As described above, when the first drive system is driven to continue the unpacking operation, as in the above, since the main and auxiliary rollers 3, 4 are worn, switching of the drive mechanism from the first drive system to the second drive system is performed. Operation.
由於副滾輪4已磨損，因此從第一驅動系統切換到第二驅動系統時，首先使第一驅動馬達7的驅動停止，接著使桿式氣缸61的可動桿部61b收縮(請參照圖5)。於是，同步用雙鏈輪55呈逆時針方向轉動約90°。隨之，第一驅動系統中，中繼用雙鏈輪53、第一鏈輪50及第一臂構件16的基端部16a藉由第一鏈條58及傳動鏈條60呈逆時針方向轉動約180°，從第一無端帶13往第一大直徑帶輪9的動力傳遞處於“斷開”狀態。同時，第二驅動系統中，第二臂構件27的基端部27a藉由第二鏈條59呈逆時針方向轉動約180°，從第二無端帶24往第二大直徑帶輪20的動力傳遞處於“接通”狀態(圖5、圖4B的狀態)。Since the sub-roller 4 is worn, when the first drive system is switched to the second drive system, the driving of the first drive motor 7 is first stopped, and then the movable lever portion 61b of the rod cylinder 61 is contracted (please refer to FIG. 5). . Thus, the synchronizing double sprocket 55 is rotated by about 90 in the counterclockwise direction. Accordingly, in the first drive system, the base double end wheel 53, the first sprocket 50, and the base end portion 16a of the first arm member 16 are rotated counterclockwise by the first chain 58 and the drive chain 60 by about 180. °, the power transmission from the first endless belt 13 to the first large diameter pulley 9 is in an "off" state. Meanwhile, in the second drive system, the base end portion 27a of the second arm member 27 is rotated by about 180 in the counterclockwise direction by the second chain 59, and the power transmission from the second endless belt 24 to the second large diameter pulley 20 is transmitted. It is in the "on" state (state of Figure 5, Figure 4B).
於此狀態下，當開始驅動第二驅動馬達8(第一驅動馬達7停止)時，第二驅動馬達8的驅動力經由第二驅動系統的第二無端帶24往第二大直徑帶輪20及第二小直徑帶輪19傳遞；與上述相反地，副滾輪4以低轉速旋轉之同時，主滾輪3以高轉速旋轉，且相互向內旋轉。In this state, when the second drive motor 8 is started to be driven (the first drive motor 7 is stopped), the driving force of the second drive motor 8 is transmitted to the second large-diameter pulley 20 via the second endless belt 24 of the second drive system. And the second small-diameter pulley 19 is transmitted; contrary to the above, while the secondary roller 4 rotates at a low rotational speed, the main roller 3 rotates at a high rotational speed and rotates inwardly toward each other.
如上所述，藉由重複馬達、帶式離合器機構及惰輪的切換操作，以持續進行脫殼作業。當採用此種桿式氣缸與鏈條‧鏈輪傳遞機構時，能簡單地藉由一個氣缸使第一驅動系統及第二驅動系統的帶式離合器機構同步。又，相較於使用複數個旋轉式致動器的情況，不需要用以使其等同步的電磁閥與邏輯繼電器等，結構簡單，亦能壓低製造成本。As described above, the switching operation of the motor, the belt clutch mechanism, and the idler is repeated to continue the unpacking operation. When such a rod type cylinder and chain sprocket transmission mechanism is employed, the belt clutch mechanism of the first drive system and the second drive system can be synchronized by one cylinder simply. Further, compared with the case of using a plurality of rotary actuators, a solenoid valve and a logic relay for synchronizing them are not required, and the structure is simple and the manufacturing cost can be reduced.
