Abstract
The application relates to a heat dissipation system of an agricultural machine, in particular to a fan transmission box device and an agricultural machine. The fan transmission box device comprises a box body, bearings, an output shaft and shaft end covers; the two sides of the box body are covered by the shaft end covers respectively; the bearings are at least two groups and are arranged at intervals in the box body; the bearings are axially positioned by at least one spacer sleeve; the output shaft penetrates through the bearings and the two ends penetrate through the box body or the shaft end covers; one end of the output shaft is provided with a joint for being connected with a fan assembly, and the other end is provided with a joint for being connected with a transmission shaft assembly. By canceling the traditional belt pulley transmission assembly, the fan assembly can be directly connected with a power output device, the arrangement height of the fan is effectively reduced, the transmission efficiency of the engine driving the fan is improved, the efficiency and air volume of the fan are improved, energy is further saved and noise is reduced.
