  Here, as shown in FIG. 1, the lower end portion of the discharge port 32d of the transport duct 32 is spaced upward by a predetermined distance H1 (for example, 25 cm) from the mounting surface 40a of the mounting table 40 in the extended posture. It becomes the height position.

  Further, as shown in FIG. 1, the lower surface 40b of the mounting table 40 in the extended position has a height position with an interval of a predetermined distance H2 (for example, 15 cm) or more upward from the center in the width direction of the cutting blade 21. Become.

  In the plucking machine 1 configured as described above, when performing the operation of cutting the tea leaves, the operator first sets the state so as to be able to travel across the bowl-shaped tea tree T according to the width of the tea tree T. While adjusting the space | interval of a pair of leg part 12, the raising / lowering apparatus 50 is driven and the height of the cutting blade 21 with respect to the tea tree T is adjusted. Here, the operator adjusts the height position of the pair of rotating brushes 31 with respect to the cutting blade 21 according to the length of the tea leaves to be cut from the tea tree T. Further, the operator attaches the tea bag B to the discharge port 32d of the transport duct 32 in a protruding posture with the mounting surface 40a of the mounting table 40 facing upward.

  Next, the operator drives the cutting blade 21, the pair of rotating brushes 31, and the blower 33 to perform the tea leaf cutting operation. The tea leaves cut from the tea tree T by the driving of the cutting blade 21 are fed rearward by the rotating brush 31 and conveyed by the air flow sent from the blower 33 and blown upward from the air outlet 34d of the airflow introduction duct 34. It circulates in the duct 32.

  The tea leaves that have circulated in the transport duct 32 are discharged rearward from the discharge port 32d of the transport duct 32. Here, the discharge port 32d is provided upwardly from the mounting surface 40a of the mounting table 40 in the extended position with a predetermined distance H1 or more, and is directed substantially in the horizontal direction. For this reason, the tea leaves discharged from the discharge port 32d are discharged in a substantially horizontal direction from the height of the predetermined distance H1 or higher upward from the mounting surface 40a of the mounting table 40. While the tea leaves discharged from the discharge port 32d fall to the placement surface 40a, the tea leaves reach a position away from the discharge port 32d in the horizontal direction, and reach the bottom side without accumulating on the entrance side of the tea bag B. To do.

  Thereafter, when the operator continues cutting the tea leaves and the tea bag B is filled with tea leaves, the operator removes the entrance of the tea bag B from the discharge port 32d on the placement surface 40a of the placement table 40 and closes the entrance of the tea bag B. The tea bag B containing the tea leaves is then placed on the loading platform 11b of the traveling machine body 11. Further, the operator performs a work of attaching a new tea bag B to the discharge port 32d when continuing the tea leaf cutting work.

  Moreover, when the plucking machine 1 moves the edge part of the bowl-shaped tea tree T, it may incline in the front-back direction of the traveling machine 10 by the inclination or level | step difference of the ground. In this case, in the plucking machine 1, since the lower surface 40b of the mounting table 40 is located at a distance H2 that is a predetermined distance or more above the height of the cutting blade 21, contact of the mounting table 40 with the tea tree T is suppressed. .

  Thus, according to the plucking machine of this embodiment, the discharge port 32d of the transport duct 32 is provided above the mounting surface 40a of the mounting table 40 with a predetermined distance H1 or more.

  Thereby, since the tea leaves can be accommodated in order from the bottom side of the tea bag B, it is possible to increase the amount of tea leaves accommodated in the tea bag B without requiring the operation of moving the tea leaves in the tea bag B. Moreover, since the operator on the mounting table 40 can bend and remove the tea bag B from the discharge port 32d, the workability of the tea bag B can be improved.

  Further, the discharge port 32d is oriented in a substantially horizontal direction.

  As a result, the tea leaves that have circulated through the transport duct 32 are discharged from the discharge port 32d in a substantially horizontal direction, so that it is possible to directly reach the bottom side of the tea bag B attached to the discharge port 32d.

  In addition, a loading platform 11b on which a tea bag B in which tea leaves are accommodated can be placed above the transport duct 32.

  Thereby, although the dimension of the front-back direction of the traveling machine 10 becomes large with the conveyance duct 32, the dimension of the front-back direction of the traveling machine 10 is utilized by utilizing the magnitude | size of the dimension of the front-back direction as a mounting space of the tea bag B. An increase in size can be prevented.

  Further, the transport duct 32 and the mounting table 40 are movable in the vertical direction with respect to the loading platform 11b.

  Accordingly, by moving the transport duct 32 and the mounting table 40 upward, it is possible to reduce the vertical distance between the tea bag B mounted on the mounting table 40 and the loading platform 11b, so that the tea leaves are accommodated. The operation | work which mounts the made tea bag B on the loading platform 11b becomes easy. In addition, since the lower surface 40b of the mounting table 40 is positioned at a distance H2 that is a predetermined distance or more above the height of the cutting blade 21, the distance between the mounting surface 40a of the mounting table 40 and the loading platform 11b can be reduced. It becomes possible, and the operation | work which moves the tea bag B in which the tea leaf was accommodated from the mounting base 40 to the loading platform 11b becomes easy.

  Further, the discharge port 32d protrudes toward the mounting table 40 from the rear end of the loading platform 11b.

  Thereby, since the operator on the mounting table 40 can visually recognize the discharge port 32d from above, the tea bag B can be easily attached to and detached from the discharge port 32d.
