Abstract

The invention provides a harvester fan wind speed adjusting device applied to the field of agricultural machines. A driving transmission wheel (1) of the wind speed adjusting device is connected with an engine (3), and a driven transmission wheel (2) is connected with a harvester fan (4). The driving transmission wheel (1) comprises a first driving disk (5), a first driven disk (6) and a screw rod (7), the first driven disk (6) is connected with a driving wheel (8), the first driving disk (5) is connected with the first driven disk (6), the first driving disk (5) is arranged on the screw rod (7) in a sleeved mode at the same time, a V-shaped structure is arranged between the first driving disk inner wall (9) of the first driving disk (5) and the first driven disk inner wall (10) of the first driven disk (6), and the driving transmission wheel (1) and the driven transmission wheel (2) are connected through a connecting belt (32). The device can achieve stepless adjustment of the fan delivery of the harvester and meet requirements of different crops for the rotating speed of a roller.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular, the invention relates to a fan wind speed adjustment device for a harvester. Background technique [0002] In the prior art, the wind speed adjustment of the fan in the combine harvester generally includes two types: 1) changing the transmission ratio by changing the pulley with different diameters and the corresponding belt, so as to change the speed of the fan of the harvester; The transmission ratio of the pulley is changed by increasing or decreasing the washer between the two transmission parts, thereby changing the speed of the fan. The two methods in the prior art are very inconvenient during the user's operation, and the adjustment of the rotating speed of the drum for different crops and different states of the same crop cannot be effectively satisfied. Contents of the invention [0003] The technical problem to be solved by the present invention is to pr...
