本考案は、コンバイン等の移動農機の走行クロ−ラ脱着装置に関するものであ る。 The present invention relates to a traveling crawler attachment / detachment device for a mobile agricultural machine such as a combine harvester.
【0002】[0002]
従来、コンバイン等において走行クロ−ラが脱輪した時の走行クロ−ラの装着 、或は走行クロ−ラ部の整備時の走行クロ−ラの脱着等の作業が容易でない。特 に大型化によって走行クロ−ラの重量も大になりアイドラ転輪のテンションボル トを弛めても走行クロ−ラ内周面がわの突起がひっかかって外れにくいように脱 着作業に時間と労力を要している。 Conventionally, it is not easy to attach a traveling crawler when the traveling crawlers are derailed in a combine or the like, or to remove or attach the traveling crawlers during maintenance of the traveling crawler portion. In particular, due to the large size, the weight of the traveling crawler also becomes large, and even if the tension bolt of the idler wheel is loosened, the inner surface of the traveling crawler will be caught in the protrusions of the ring and it will take time to remove it. And labor is required.
【0003】[0003]
この考案は、上記のように走行クロ−ラの脱着作業が困難であることから、そ の困難な作業を容易にしてこれに要する時間の短縮と省力化をはからんとするを 目的として考案に至ったものである。 This invention is difficult to attach and detach to the traveling crawler as described above, and is devised for the purpose of facilitating the difficult task, shortening the time required for this task, and saving labor. It came to.
【0004】[0004]
そこで、本考案は上記の目的を達成させるために、前後部の駆動スプロケット とアイドラ転輪と、この駆動スプロケットとアイドラ転輪の間に配置した各転輪 に走行クロ−ラを懸回してなる移動農機において、前記アイドラ転輪を支持する 水平状保持部材の基部がわを、トラックフレ−ムがわの縦軸に嵌合し、アイドラ 転輪を縦軸を支点にして外側方に回動可能に構成したことを特徴とする。 Therefore, in order to achieve the above-mentioned object, the present invention comprises a driving sprocket and an idler wheel at the front and rear parts, and a traveling crawler suspended around each of the wheels arranged between the drive sprocket and the idler wheel. In a mobile agricultural machine, the base of the horizontal holding member that supports the idler wheel is fitted to the vertical axis of the track frame, and the idler wheel is pivoted outward with the vertical axis as the fulcrum. It is characterized by being configured as possible.
【0005】[0005]
したがって、走行クロ−ラを装着する場合は、アイドラ転輪を支持する保持部 材の基部がわを縦軸を支点にして外側方に回動させてアイドラ転輪を外がわに変 位させるとともに、このアイドラ転輪の周縁部と走行クロ−ラの内周面との間に 余裕をもたせる状態にして、走行クロ−ラをアイドラ転輪に掛け廻したのち保持 部材を内方がわに向け復動させることによって装着でき、また、走行クロ−ラを 外す場合は、前記の保持部材を外側方に回動させると、アイドラ転輪は外がわに 変位し、かつ、アイドラ転輪と走行クロ−ラ内周面との間に余裕ができて容易に 外れるようになる。 Therefore, when the traveling crawler is installed, the base of the holding member that supports the idler wheel is rotated outward with the vertical axis as the fulcrum to displace the idler wheel to the outer wheel. At the same time, with a margin between the peripheral edge of the idler wheel and the inner peripheral surface of the running crawler, the running crawler is hung around the idler wheel, and then the holding member is bent inside. It can be mounted by turning back and forth, and when removing the traveling crawler, if the holding member is rotated outward, the idler wheel will displace to the outer ring and There is a space between the inner surface of the traveling crawler and it can be easily removed.

【0008】 また、(4)は前記縦フレ−ム(7)の外側においてこれと平行に設けられた 角形中空状のトラックフレ−ムで、このトラックフレ−ム(4)にはそれぞれ前 側から第1転輪(12)・イコライザ転輪(13)・第2転輪(14)・第3転 輪(15)の順に配設支持されて後部にはアイドラ転輪(2)を設け、この各転 輪(12)(13)(14)(15)とアイドラ転輪(2)を備える左右のトラ ックフレ−ム(4)の前部と後部は連結パイプ(16)と(17)によって連結 され、この連結パイプ(16)(17)に前記リンク(8)(9)の後端部を回 動自在に嵌合させ、このリンク(8)(9)を支点軸(10)(11)を軸にし て上下に揺動させることによって左右のトラックフレ−ム(4)は上下に位置が 変更されるのである。Further, (4) is a rectangular hollow track frame provided outside the vertical frame (7) in parallel therewith, and the front side of each of the track frames (4). The first wheel (12), the equalizer wheel (13), the second wheel (14), and the third wheel (15) are arranged and supported in this order, and the idler wheel (2) is provided at the rear. The front and rear parts of the left and right truck frames (4) provided with the wheels (12), (13), (14) and (15) and the idler wheels (2) are connected by connecting pipes (16) and (17). The rear ends of the links (8) and (9) are rotatably fitted to the connection pipes (16) and (17), and the links (8) and (9) are connected to the fulcrum shafts (10) and (11). ) As the axis, the left and right track frames (4) are vertically displaced. It will be changed.
【0009】 そして、エンジンからの動力を入力するミッションケ−スからはファイナルケ −スが左右がわに突設して縦フレ−ム(7)から前方に延設する支持体(18) によって支持されて、ファイナルケ−スに内装の駆動軸(19)の端部に駆動ス プロケット(1)が軸着され、走行クロ−ラ(a)はこの最前部の駆動スプロケ ット(1)と前記数個の転輪とアイドラ転輪(2)および縦フレ−ム(7)に支 持された上側のキャリアロ−ラ(20)とに懸回されている。The final case projects from the transmission case into which the power from the engine is input to the left and right sides by a support body (18) extending forward from the vertical frame (7). The drive sprocket (1) is supported and the drive sprocket (1) is pivotally attached to the end of the drive shaft (19) of the interior of the final case, and the traveling crawler (a) is the front drive sprocket (1). It is suspended by the above-mentioned several rollers, an idler roller (2) and an upper carrier roller (20) supported by a vertical frame (7).
【0010】 そこで、本考案の要部について「図1」と「図2」により記載すると、前記ト ラックフレ−ム(4)の後部からは中空の支持フレ−ム(21)が外側方に向け 突設され、その突出端部に縦軸(5)が立設されている。(3)は前記のアイド ラ転輪(2)を支持する保持部材で、後方に向けての附勢力を内蔵する左右の保 持杆(22)(22)を2つの横杆(23)(24)によって連結し、この左右 の保持杆(22)(22)の後端部の間にアイドラ転輪(2)を位置させて回動 自在に支持している。Therefore, the main part of the present invention will be described with reference to FIG. 1 and FIG. 2. A hollow support frame (21) is directed outward from the rear part of the track frame (4). It is projected, and the vertical axis (5) is erected on the protruding end. (3) is a holding member for supporting the idler rolling wheel (2), and the left and right holding rods (22) and (22) having a built-in biasing force toward the rear are provided with two horizontal rods (23) ( 24), and idler wheels (2) are positioned between the rear ends of the left and right holding rods (22) and (22) to rotatably support them.
【0011】 そして、前記前側の横杆(23)を前記の立設する縦軸(5)に嵌合させて保 持部材(3)をアイドラ転輪(2)と共にこの縦軸(5)を支点にして水平状態 で外側方に回動可能に構成し、また、内側の保持杆(22)の基部がわから固定 用の板体(25)を支持フレ−ム(21)の後面がわにそわせて垂設し、その下 端部を支持フレ−ム(21)の下面に固設する板片(26)に締結具(27)に より締合自在にしている。Then, the front side horizontal rod (23) is fitted to the vertical axis (5) which is erected so that the holding member (3) is moved along with the idler wheel (2) along the vertical axis (5). It is constructed so that it can be rotated outward in a horizontal state with the fulcrum as the fulcrum. Further, the base of the inner holding rod (22) is fixed to the plate (25) for fixing, and the rear surface of the support frame (21) is bent. The lower end portion is vertically attached to the plate piece (26) fixed to the lower surface of the support frame (21) by a fastener (27).
【0012】 これによって、締結具(27)により板体(25)の下端部を板片(26)に 締合すると保持部材(3)は前後方向の姿勢でアイドラ転輪(2)を強固に支持 し、懸回する走行クロ−ラ(a)を回行させるのである。Accordingly, when the lower end portion of the plate body (25) is fastened to the plate piece (26) by the fastener (27), the holding member (3) firmly fixes the idler wheel (2) in the front-back posture. It supports and circulates the suspended running crawlers (a).
【0013】 また、締結具(27)を解き保持部材(3)を縦軸(5)を支点にして外側方 に向け回動させると、板体(25)の下端部は板片(26)から解離しながらア イドラ転輪(2)と共に仮想線(イ)で示す状態になって、アイドラ転輪(2) は外がわに変位し、このアイドラ転輪(2)と走行クロ−ラ(a)内周面との間 が開いて余裕ができ走行クロ−ラ(a)は容易に外せるようになる。また、走行 クロ−ラ(a)を装着するときは前記と逆の動作により行うのであってこれによ り装着も容易になる。When the fastener (27) is unfastened and the holding member (3) is rotated outward with the vertical axis (5) as a fulcrum, the lower end of the plate body (25) is a plate piece (26). While disengaging from the idler rolling wheels (2), the idler rolling wheels (2) and the idler rolling wheels (2) are displaced to the outer ring. (A) A clearance is provided between the inner peripheral surface and the inner peripheral surface so that the traveling crawler (a) can be easily removed. Further, when the traveling crawler (a) is mounted, it is carried out by the reverse operation to the above, which facilitates the mounting.
【0014】 なお、この走行クロ−ラ(a)の脱着の場合に、「図4」で示すように上側の キャリアロ−ラ(20)を下方に変位させるようにすると、さらに、その脱着が 容易になる。即ち、キャリアロ−ラ軸(28)を外側部(28a)と内側部(2 8b)に分割しこれをジョイント(29)にて連結し、トラックフレ−ム(4) に外側方に向け嵌挿するところの固定パイプ(30)に挿通して摺動自在にし、 圧縮スプリング(31)により内側部(28b)に内向きの附勢力を与える構成 にすれば、走行クロ−ラ(a)の脱着時にキャリアロ−ラ(20)を圧縮スプリ ング(31)の附勢力に抗して外側方に引くと,外側部(28a)と内側部(2 8b)は連結状態で固定パイプ(30)内を摺動して「図5」のように外側部( 28a)はジョイント(29)部から下方に折曲しキャリアロ−ラ(20)は下 方に変位するのである。In addition, in the case of detaching the traveling crawler (a), if the upper carrier roller (20) is displaced downward as shown in FIG. It will be easier. That is, the carrier roller shaft (28) is divided into an outer part (28a) and an inner part (28b), which are connected by a joint (29), and fitted to the track frame (4) outward. If the structure is such that the fixed pipe (30) where it is inserted is slidable and the compression spring (31) gives an inward biasing force to the inner portion (28b), the traveling crawler (a) When the carrier roller (20) is pulled outwards against the urging force of the compression spring (31) during desorption, the outer part (28a) and the inner part (28b) are connected and the fixed pipe (30) is attached. By sliding inside, the outer portion (28a) is bent downward from the joint (29) portion as shown in FIG. 5, and the carrier roller (20) is displaced downward.

本考案による脱着装置は以上述べたように、前後部の駆動スプロケット(1) とアイドラ転輪(2)と、この駆動スプロケット(1)とアイドラ転輪(2)の 間に配置した数個の転輪に走行クロ−ラ(a)を懸回してなる移動農機において 、前記アイドラ転輪(2)を支持する水平状保持部材(3)の基部がわを、トラ ックフレ−ム(4)がわの縦軸(5)に嵌合し、アイドラ転輪(2)を縦軸(5 )を支点にして外側方に回動可能に構成したのであるから、アイドラ転輪(2) を支持する保持部材(3)を外側方に回動させるだけの簡単な構成によってアイ ドラ転輪(2)を外がわに変位し、かつ、アイドラ転輪(2)と走行クロ−ラ( a)内周面との間に余裕ができるようになって走行クロ−ラ(a)の脱着が容易 となり作業時間は短縮し労力は省力化されるものになる。 As described above, the attachment / detachment device according to the present invention includes the drive sprocket (1) and the idler wheel (2) at the front and rear portions, and the several sprocket (1) and the idler wheel (2) arranged between the drive sprocket (1) and the idler wheel (2). In a mobile agricultural machine in which a traveling wheel (a) is suspended on a wheel, a base of a horizontal holding member (3) that supports the idler wheel (2) is attached to a track frame (4). Since the idler wheel (2) is fitted to the vertical axis (5) of the shaft and is rotatable outwardly about the vertical axis (5) as a fulcrum, the idler wheel (2) is supported. By simply rotating the holding member (3) outward, the idler wheel (2) is displaced to the outer ring, and the idler wheel (2) and the running crawler (a) A clearance can be created between the peripheral surface and the traveling crawler (a) so that it can be easily attached and detached. Shortened effort is made to those labor-saving.
