In this state, the backing plate 15 is in a forward tilted posture. The corn tuft Aa on the receiving plate 15 is scraped and collected by the tine 29 passing between the adjacent receiving plates 15.

  Further, in the state where the cutting unit 3 is raised, the rear mesh member 17 has the same height as the scraping reel 10. At this time, the rear mesh member 17 is a mesh-like member, so that the driver can visually recognize the front from the driver seat 21 (for example, the range of R2 in FIG. 20) without impairing the visibility.

  Here, in the case of corn, the cocoon is thick and hard, and the height of the residue is increased by the high mowing operation. Then, there is a concern that the residue may be caught by a hydraulic hose (not shown) or a harness (not shown) on the lower side of the machine body frame 2 to be damaged. Therefore, in order to avoid such a situation, a cover (not shown) that covers the hydraulic hose and the harness partially or entirely to protect them is provided.

[Another embodiment]
(1) As shown in FIG. 21, a mesh-like divider 160 may be attached to the left divider 9L located on the uncut side. Here, if the divider is formed of a transparent plate made of resin, the transparent plate is scratched by the cutting operation, and the visibility is likely to deteriorate. However, since the divider 160 is a mesh-like member, the guidance status of the crop can be visually recognized, and the visibility is hardly reduced. Further, it is possible to prevent the planted crop from being wound around the take-up reel 10.

(2) In the above embodiment, an operation mode for harvesting corn as a crop is assumed, but an operation mode for harvesting crops such as rice, wheat, buckwheat, and soybeans may be used.

(3) The shape and material of the stay 57 are not limited to the shape and material according to the above embodiment, and various shapes and materials can be employed.

(4) In the above embodiment, the support structure of the stay 57 and the lateral frame 33 is adopted as the support structure of the receiving plate 15, but other support structures may be adopted.

(5) In the above embodiment, the receiving plate 15 is constituted by a corrugated plate member. However, for example, the receiving plate 15 may be constituted by a flat plate member, or may be constituted by an arc-shaped plate member. Also good. That is, the shape and material of the backing plate 15 are not limited to the shape and material according to the above embodiment, and various shapes and materials can be employed.

(6) In the above embodiment, the tine 29 is formed in a T-shaped cross section, but may be constituted by a claw-type tine.

(7) In the above embodiment, the tine 29 is made of a metal member, but may be made of a resin member.

  The present invention is applicable to a combine harvester for harvesting crops such as rice, wheat, buckwheat, soybean, and corn.
