Title:
REVERSING DEVICE FOR HEAT DISSIPATION FAN OF HARVESTER
Document Type and Number:
WIPO Patent Application WO/2021/232580
Kind Code:
A1
Abstract:
A reversing device for a heat dissipation fan of a harvester, comprising an engine driving wheel (1), a transition wheel part (4), an intermediate wheel group (9), a tension wheel part (5), a heat dissipation fan assembly (7), and a belt group, the intermediate wheel group (9) being mounted on an intermediate wheel mounting frame (91). The device solves the problem that the whole machine is excessively wide due to the installation of a heat dissipation water tank and a dust screen outside an engine suction fan, thus preventing the harvester from hitting the ridge; and solves the problem of high engine temperature caused by dust screen blockage by dust, poplar, wheat ash, and the like due to continuous suction of the engine suction fan. The reversing device can achieve forward and reverse control by controlling a reversing tension push rod, thus enabling conveniently and quickly switch to the reverse state at any time.
