When traveling forward, branches and leaves cut by the cutting device 40 flow in the transport duct 31 by the air flow and are discharged into the space 68 of the container 51. Here, the air discharged from the transport duct 31 is discharged to the outside from the meshes 55 and 53 provided on the upper plate 54 and the back plate 52 and the mesh 62 of the housing body 61. Therefore, the branches and leaves discharged into the container 51 are separated from the air flow and moved to the bottom side of the container 51 due to their own weight.

  When the inside of the container 51 is filled with branches and leaves, the tea leaf plucking machine 1 is moved to a predetermined position in the field, the container 51 is lifted by the lifting device 70, and moved onto a loading platform such as a truck stopped at the predetermined position. The wire 59 is operated to rotate the bottom plate portion of the lower plate 57 to move the branches and leaves from the inner hole portion onto the loading platform.

  In this way, even when the branches and leaves are filled in the container 51, the containers 51 can be reused by discharging the branches and leaves from the container 51 to a truck bed or the like. For this reason, it is not necessary for the operator to replace the container 51, and the labor of the operator can be reduced.

  On the other hand, when storing the storage device 50, as shown in FIG. 4, the lower plate 57 is moved from the deployed position Pb1 to the folding position Pb2, and then the upper plate 54 is moved from the deployed position Pa1 to the folded position Pa2. . When the upper plate 54 and the lower plate 57 are rotated, the housing body 61 is deformed and folded. For this reason, the rotation of the upper plate 54 and the lower plate 57 is not restricted by the housing body 61.

  Thus, when storing the storage device 50, the upper plate 54 and the lower plate can be rotated while the storage body 61 is attached to the upper plate 54 and the lower plate 57. The operation is easy, and the labor of the storage operation can be reduced. Moreover, since the accommodating drum 61 is formed of a deformable net, the structure of the accommodating device 50 can be simplified, the cost of the accommodating device 50 can be reduced, and the weight can be reduced. Furthermore, since the storage device 50 is reduced in weight, it is possible to improve operability when the operator rotates the upper plate 54 and the lower plate 57.

  When storing the storage device 50, in order to facilitate the folding of the storage barrel 61, the upper end of the storage barrel 61 is removed from the upper plate 54, and the other portions are left connected. 54 and lower plate 57 may be rotated to fold housing cylinder 61.

  Further, as shown in FIG. 5, when the storage device 50 is stored, the upper plate 54 and the lower plate 57 move to positions along the connecting pillar 35. For this reason, it can suppress that the front-back direction length of the tea leaf plucking machine 1 becomes large, and the possibility that the balance of the front-back direction of the tea leaf plucking machine 1 may worsen can be prevented.

  In the above-described embodiment, the case where the housing body 61 is connected to the back plate 52 is shown. However, the housing body 61 is formed in a cylindrical shape, and the upper plate 54, the lower plate 57, and the housing body 61. Thus, a space 68 that can accommodate branches and the like may be formed.

  Further, the present invention is not only applied to the tea leaf plucking machine 1, but can also be applied to, for example, a riding type plucking machine, a riding type pruning machine, an agricultural working machine, and the like.
