Operator cab for work vehicles

Abstract

An operator cab (8) for work vehicles comprises: an operator cab body (11) in which an access opening (21) and a vent opening (22) are formed; a door (12) that opens and closes the access opening (21); a cover (13) that opens and closes the vent opening (22); a link mechanism (14) that links the door (12) and the cover (13) so that that cover (13) opens when the door (12) opens and the cover (13)closes when the door (12) closes; and a closing timing regulator (15) that stops a closing operation of the cover (13) during a first stage of an operation to close the door (12) and allows the closing operation of the cover (13) during a second stage of the operation to close the door (12), which is after the first stage.

Description

technical field [0001] The present invention relates to a cab of a work vehicle. [0002] This application claims priority based on Japanese Patent Application No. 2018-147031 filed on August 3, 2018, and the content thereof is incorporated herein. Background technique [0003] Cabs of work vehicles such as dump trucks operating at mining sites or civil engineering sites require high airtightness in order to prevent sand and dust from entering from the outside and to maintain the indoor temperature adjusted by air conditioners and the like. Patent Document 1 discloses a configuration in which a ventilation port formed in a cab is opened when a door opening operation is detected, and a ventilation port is closed when a door closing operation is detected. In this configuration, when the door of the cab is closed, the air in the cab flows out through the ventilation port, thereby suppressing an instantaneous increase in the air pressure in the cab. As a result, the door of th...
