  In a self-propelled processing machine, it is necessary to perform work such as repair or replacement of parts due to damage to the processing apparatus due to foreign matters mixed therein, cleaning, or maintenance for eliminating clogging of processed materials. In such work, the work efficiency is greatly improved by accessing the processing device from the processing unit discharge unit side (for example, the lower side of the processing device) from the processing device to the carry-out conveyor. The gap between the conveyors is often very narrow.

  In the self-propelled processing machine described in the above prior art, it is possible to secure the work space by removing the carry-out conveyor during work, and to resume the work by attaching the carry-out conveyor after the work.

  However, in the above prior art, by inserting a notch provided in the lower part on one end side of the carry-out conveyor into the bridge portion and fixing the other end side to a bracket provided in the main body frame by a fixing pin, Keep the unloading conveyor in the unloading posture to unload the processed material. For this reason, in the removal work for pulling out the carry-out conveyor from the self-propelled processor and the installation work for insertion, it is necessary to make the carry-out conveyor parallel (horizontal) to the ground. Therefore, the removal and installation work of the carry-out conveyor is not easy and there remains room for improvement.

And a main body frame which is arranged at a position higher than the right traveling device and is coupled to the left support column and the right support column, a processing device installed on the main body frame, and a processing object which is unloaded from the processing device. In the self-propelled processing machine provided with a carry-out conveyor, the carry-out conveyor is inserted between the left column and the right column above the transfer unit, and is inserted in parallel with the ground and withdrawing direction. Move to A guide means for guiding the, shall be secured to the traveling device side of the left and right profile and can be moved to the ground and parallel to the direction.

  As described above, since the movement in the insertion direction and the drawing direction of the conveyor is performed in parallel with the ground while maintaining the unloading posture, complicated operations such as changing the posture of the unloading conveyor in the detaching operation and the mounting operation are performed. Therefore, it is possible to easily remove and attach the unloading conveyor for unloading the processed material discharged from the processing apparatus.

  (2) In the above (1), the carry-out conveyor has at least the rack in the carry-out posture and a transfer surface that becomes higher toward the downstream side where the processed material is carried out, and in the movement in the insertion direction and the pull-out direction. It is assumed that a portion passing over the transfer portion has a lower structure positioned above the transfer portion.

  (3) In the above (1) or (2), the guide means is provided on one of the carry-out conveyor and the transfer part, and extends in the insertion direction and the pull-out direction above the transfer part. An existing guide rail and a guide roller that rolls along the guide rail are provided on the other side of the carry-out conveyor and the transfer section.

  (4) In any one of the above (1) to (3), the carry-out conveyor is conveyed downstream by the first conveyor inserted between the left strut and the right strut, and the first conveyor. The second conveyor is further supported by a bracket extending from the main body frame, and the second conveyor is connected to the bracket of the first conveyor. It is assumed that a retracting means for retracting from the drawing line is provided.
