Description

  The present invention relates to a combine equipped with a branch-branch processing device.

  Conventionally, a combine has a cutting part, a threshing part, and a sorting part that swings and wind-sorts the grains threshed by the threshing part. Dust feeding processing cylinder that connects the mouth to the mouth and reprocesses the threshing of the handling cylinder in parallel on the side of the rear side of the handling cylinder, and also processes the second branch etc. above the sorting section After the equipment is installed and the branch leaves etc. are removed from the second thing sent to the branch-branch processing device via the second conveyor and the reduction conveyor, the second treatment is returned to the sorting start part of the swing sorting device again. It is configured so as to perform rocking sorting and wind sorting by returning (described in, for example, Patent Document 1 (Japanese Patent Laid-Open No. 2004-033154)).

  In many cases, the branch raft processing apparatus is generally disposed in the vicinity of the handling chamber. For example, in the combine described in Patent Document 1 (Japanese Patent Application Laid-Open No. 2004-033154), the handling chamber is provided. In the combine described in Patent Document 2 (Patent No. 2953458), it is disposed in the form of a screw conveyor on the lower lateral side along the handling chamber. 3 (Japanese Patent Laid-Open No. 6-032734) is arranged in the form of a screw conveyor extending in front of the dust feeding cylinder on the upper side of the handling chamber.

  However, as a different position, in Patent Document 4 (Japanese Patent Laid-Open No. 2008-61523), a branch-branch processing unit is provided at the start end and the end end of the second reduction conveyor, respectively. There is one in which the second post-branch treatment is carried directly into the supply port on the rear side of the handling room.

  As described above, the extending form of the second reduction conveyor differs depending on the arrangement position of the branch rachis processing apparatus. For example, if the branch raft processing apparatus is arranged close to the front part of the handling chamber, The number reduction conveyor is inclined forward, and has a long structure in which the terminal end communicates with the branch rachis processing apparatus. However, like the combine described in the above-mentioned Patent Document 1 (Japanese Patent Application Laid-Open No. 2004-033154), the branch reduction device is disposed on the lateral side of the front lower part of the handling chamber. In the case of rearward tilting, the second reduction conveyor is made shorter and more compact to simplify the overall structure of the aircraft.

  In such a technique, it is necessary to interpose a return conveyor between the second reduction conveyor and the branch-pruning apparatus. That is, the second thing is returned by interposing a return conveyor extending in the front-rear direction between the upper end of the rearwardly inclined second reduction conveyor and the branch-branch processing apparatus disposed on the lateral side of the front part of the handling chamber. It is conveyed to the branch-branch processing device via a conveyor.

In this way, the position of the branch-branch processing device is basically arranged in front of the second reduction conveyor, that is, in the vicinity of the handling chamber, and the branch-branched second product is returned to the sorting start unit of the swing sorting device. I try to reprocess it. However, when the position of the branch raft processing device is set in the vicinity of the handling chamber in this way, the second item with a branch raft must be transported from the second conveyor to the branch raft processing device, and is selected using a return conveyor. It is made to carry in to the start end part of a part (combine described in patent document 1).

  In this way, the branch rachis processing apparatus 11 is formed so as to bypass the branch rachis processing path U from the transport path D of the return conveyor 24, so that the branch rachis processing apparatus 11 is projected over the side of the selection unit 5. It is not necessary to provide a space in which the branching device 11 is provided in the space of the selection unit 5 only in the formed and overhanging portion, and this does not hinder the space for important selection processing.

  Further, since the branch rachis processing path U is disposed outside the threshing unit 4 and the sorting unit 5, the branch rachis processing device 11 is arranged in a form protruding outside the sorting unit 5. Therefore, it is possible to easily attach the protruding branch-flower processing device 11 and the arrangement space K in which the branch-flower processing device 11 is provided has a relatively large space, and maintenance is performed from this space. It is easy, and it can be set as the structure where maintenance of the branch branch processing apparatus 11 is easy to do easily by this.

  And as above-mentioned, the arrangement | positioning space K just before the outer side wall of the threshing part 4 and the Glen tank 35 is an existing space where the 2nd reduction | restoration conveyor 10 is arrange | positioned. For this reason, by arranging the branch rachis processing apparatus 11 in the existing space, the branch rachis processing apparatus 11 that forms the branch rachis processing path U is disposed just before the threshing part or the sorting part. However, it is not necessary to form a space for disposing the branch rachis processing apparatus 11 for the branch rachis processing path U. Therefore, this space can be effectively used to form the branch rachis processing path U, and there is no need for structural modification.
