The engagement member 45 is fixed to the first carrier rod 33. The guide rollers 46 are attached and fixed to the inner side surfaces of the side frames 7L, 7R. As the endless conveyance body 21 cyclically moves, the engagement member 45 comes in contact with the guide roller 46 and climbs up and falls when passing through the guide roller 46. Vibration is imparted to the endless carrier 21 by this. The crop excavated by the moat body 3 is placed on the endless carrier 21 together with the soil. By applying vibration to the endless carrier 21, the soil placed on the endless carrier 21 can be sieved off.

  In the conventional harvester, if the distance between the conveying weirs is increased so that the soil may fall off easily, small crops such as small chops fall from between the conveying weirs. Therefore, if the pitch of the transport weirs is reduced so that small crops do not fall between the transport weirs, the soil separation performance is degraded. When the separation performance of the soil is lowered, the soil dropped downward from the transport path portion 28 is accumulated on the return path portion 29 and the soil is retained between the return path portion 29 and the transport path portion 28.

  In the present embodiment, the adjacent spacing (indicated by arrow Y1 in FIG. 2) between the first and second transport rods 33 and 34 in the transport path portion 28 and the adjacent spacing between the first and third transport rods 33 and 35 (see FIG. The arrow Y2 in 2) is used as an interval at which small crops such as small chops do not fall. By this, small crops such as chute can be transported without falling. In addition, in the return path portion 29, the second transport bar 34 retracts from between the first transport bars 33, so that the discharge of the soil in the return path portion 29 is improved. This prevents the soil separation performance in the return path portion 29 from being degraded. Since the fall of the separation performance of the soil in return way part 29 can be prevented, it can prevent that soil stays between return way part 29 and conveyance way part 28.

As described above, it is possible to provide a harvester 1 capable of transporting small crops such as chute and preventing soil from staying between the return path portion 29 and the transport path portion 28. Can.
In addition, the support member 40 for supporting the second transfer rod 34 can be engaged with and disengaged from the pivot 41 supported by the first transfer rod 33A on the front side in the movement direction A and the first transfer rod 33B on the rear side in the movement direction A. And an engaging portion 42 engaged with the As a result, the second transfer rod 34 can be supported so as to be changeable in position between the first position B 1 between the first transfer rods 33 and the second position B 2 retracted from between the first transfer rods 33.

Further, the engaging portion 42 engages with the rear first transfer rod 33B in the transfer path portion 28 from the upper side,
When reaching the return path portion 29 from the transport path portion 28, the support member 40 is disengaged downward from the rear side first transport rod 33B by rotating under its own weight. This can simplify the structure.
In addition, the endless conveying body 21 may be configured by the endless chain 32, the first conveying rod 33, and the second conveying rod 34, but in the present embodiment, between the first conveying rods 33 adjacent in the moving direction A. By providing the third transport weirs 35 arranged so as not to be able to change the position, the number of the second transfer weirs 34 that can change the position can be reduced, and the structure of the endless conveyance body 21 can be simplified.

Also, by alternately providing the second transport weir 34 and the third transport weir 35 in the moving direction A, even when the third transport weir 35 is provided, the soil separation performance at the return path portion 29 is favorably reduced. Can be prevented.

  In the vibration applying mechanism 62, when the rotating member 63 rotates, the first link 64 swings back and forth around the pivot 67. When the first link 64 swings back and forth, the second link 65 is pushed and pulled back and forth, and the support frame 50 reciprocates back and forth. Vibration is imparted to the cage 47 by this. By vibrating the cage 47, the discharge of soil from the cage 47 is promoted.

In addition, as shown in FIG. 10, the harvester 1 extracts a crop (in the present embodiment, a "cholet" which is a tuber) from a basic organ of a plant (a basic part of a plant composed of stems, leaves, roots and the like). It has the separation member 71 which makes it separate.
As shown in FIGS. 7 and 8, the separating member 71 is made of a plate material, and has a mounting base 72 and a handle 73 extending upward from the mounting base 72.

The mounting base 72 is formed to be horizontally long in the lateral direction, and is mounted to the support frame 50 (specifically, the rear rail member 57).
The handle portion 73 has a plurality of handle teeth 74 extending upward from the mounting base 72. The teeth 74 are arranged side by side at intervals in the left-right direction. Each of the teeth 74 has a lower first portion 75 extending straight upward from the mounting base 72 and an upper second portion 76 extending obliquely upward from the first portion 75.

The chorage 77 is a crop that is easily detached from the root, but there is a crop that is left housed in the cage 47. It takes time and effort to separate the chorus 77 remaining in the root manually one by one. In the present embodiment, the chute 77 can be easily separated by passing the remaining root of the chute 77 through the scrubbing portion 73.
As shown in FIGS. 9 and 11, the transport device 4 has a cover 78 formed of an elastic plate such as a rubber plate. The covers 78 are disposed on the left and right sides on the upper surface side of the endless conveyance body 21, and are provided from the front end to the rear end of the conveyance path portion 28. An upper portion 78a of the cover 78 is attached to the inner surface side of the side frames 7L, 7R by bolts or the like. The lower portion 78 b of the cover 78 covers the top and bottom sides of the endless carrier 21 from the top so as to cover the engagement space 44.

Since the transport device 4 has an engagement space 44 between the support member 40 and the outer link 37 in order to insert the engagement projection 26 of the drive wheel 19, the crop can be removed from the engagement space 44. There is a risk of falling. By providing the cover 78, it is possible to prevent the crop from falling from the engagement space 44 between the support member 40 and the outer link 37.
In the said embodiment, although the endless conveyance body 21 which has the endless chain 32, the 1st conveyance rod 33, the 2nd conveyance rod 34, and the 3rd conveyance rod 35 was illustrated, it is not limited to this.
