The manual adjusting mode is that an adjusting button is included in a cab of the harvester, and a driver can adjust and control the harvester through the adjusting button. The automatic adjusting mode refers to the adjusting method for the grain loss of the harvester, and can automatically adjust all parameters of the harvester according to the screen loss data and the roller entrainment loss data.
The harvester also includes a display device, the display screen includes a control panel through which a user can input control instructions for the harvester. Specifically, a user can switch to a manual adjusting mode through a trigger button, and a driver performs manual button control on corresponding electromagnetic valves to perform control adjustment according to the screen mesh loss number and the roller entrainment loss number displayed by a display screen in a cab. The control operation of the user for the screen is called a first control operation, the control operation of the user for the roller is called a second control operation, and after the first control operation of the user for the screen and the second control operation of the roller are received, the vehicle control unit can correspondingly adjust the opening degree of the screen and/or adjust the roller proportional valve group.
The specific manual operation process comprises the following steps: if the screen cloth loss number is too much, the screen cloth loss reaches first default promptly, the driver can judge according to the site operations condition, carry out the sieve piece aperture through the three button of sieve piece aperture adjustment button (preceding sieve, back sieve, tail sieve) above the control panel and adjust, carry out the wind speed size through the wind speed rotational speed adjustment button above the control panel and adjust, adjust through four concave board clearance motors of concave board clearance adjustment button (concave board clearance left front, concave board clearance left back, concave board clearance right front, concave board clearance right back) above the control panel. If the display screen shows that the number of the entrainment losses of the roller is too large, namely the loss of the roller reaches a second preset value, a driver can carry out roller speed regulation control through a roller rotating speed increasing and decreasing button on the control panel, and if the display screen shows that the rotating speed value of the roller is too low, the driver properly reduces the speed of the vehicle through the electric control handle. In the manual mode, a driver can realize man-machine interaction through the control panel according to related information displayed by the display screen so as to realize the control operation of the harvester.
