1. A harvester comprising a raking reel configured to rake in planted
grain stalks,
5 wherein the raking reel includes:
a rotation shaft configured to be rotatable about a rotation
axis extending along a left-right direction of a body of the harvester;
left and right reel frames supported by the rotation shaft and
configured to be rotatable about the rotation axis together with the rotation
10 shaft;
a plurality of tine support members disposed at intervals
around the rotation axis and extending between an outer peripheral portion
of the left reel frame and an outer peripheral portion of the right reel frame;
and
15 a plurality of tines disposed at intervals in a direction along
the rotation axis on each of the plurality of tine support members and
configured to rake in planted grain stalks, and
the reel frames each have a circular outer peripheral shape.
20 2. The harvester according to claim 1,
wherein the reel frames are constituted by disc-shaped members.
3. The harvester according to claim 2,
wherein the outer peripheral portion of each of the reel frames
25 includes a bent portion that is bent toward the rotation axis, has a ring shape,
and extends along a whole circumference of the outer peripheral portion of
the reel frame.
4. The harvester according to claim 3, further comprising
30 support members supporting lateral end portions of the tine support
members at positions corresponding to the plurality of tine support members
in the outer peripheral portion of each of the reel frames,
wherein the support members are supported by the bent portion.
35 5. The harvester according to any one of claims 2 to 4,
wherein each of the reel frames is increasingly recessed toward one
13
side in the direction along the rotation axis while extending from the outer
peripheral portion of the reel frame toward a center portion of the reel frame.
6. The harvester according to claim 5,
5 wherein each of the reel frames is increasingly recessed toward a
center in a left-right direction of the raking reel in the direction along the
rotation axis while extending from the outer peripheral portion of the reel
frame toward the center portion of the reel frame.
10 7. The harvester according to any one of claims 2 to 6,
wherein the reel frames include an opening that is open in the
direction along the rotation axis.
8. The harvester according to claim 1,
15 wherein each of the reel frames includes:
a ring-shaped outer peripheral frame constituting the outer
peripheral portion of the reel frame;
a support portion provided in a center portion of the reel frame
and supported by the rotation shaft; and
20 a plurality of leg portions disposed at intervals around the
rotation axis and extending between the outer peripheral frame and the
support portion.
9. The harvester according to claim 8,
25 wherein the leg portions are coupled to the outer peripheral frame.
10. The harvester according to claim 9, further comprising
support members supporting lateral end portions of the tine support
members at positions corresponding to the plurality of tine support members
30 in the outer peripheral portion of each of the reel frames,
wherein the support members are on lines along which the leg
portions extend in a side view.
