Description

  The present invention relates to a combine provided with a cutting unit, a threshing unit, a grain tank, a driving seat, and a safety frame on a traveling machine body.

  As a combine configured as described above, Patent Document 1 describes a configuration in which a safety frame is provided behind a driver seat. In this patent document 1, the safety frame is a gate type in which a lower end portion is fixed to a front plate of a grain tank (a storage tank in the document) behind a driver seat, and an intermediate frame portion extending in the lateral direction at the upper part. The part is formed with a recess for supporting a swiveling cylinder for discharging the grain from the grain tank.

  In this Patent Document 1, when the swivel tube is swung at a low height, the swirl tube is brought into contact with the safety frame, thereby preventing contact with the driver during the turn and ensuring safety. Further, in this configuration, since the upper end of the safety frame is at a level that protects the driver, the driver can be protected when the traveling machine body falls.

  Moreover, in patent document 2, a driver's seat is arrange | positioned in the front part of a grain tank (literature tank in literature), and a pair of support | pillar which supports the canopy roof above a driver's seat is arrange | positioned in the front of a grain tank. Yes. The pair of struts reinforce each other and are also configured to serve as a safety frame.

  Although it is not a combine, Patent Document 3 includes a single front strut disposed in front of the driver seat and has a pair of left and right rear struts disposed rearward of the driver seat. A safety frame (in the literature, a driver's seat protection frame) including a roof frame disposed above is shown.
