Sequence, can be general to most of threshing grounds, and individual special threshing grounds, driver can carry out more certain programs on operation panel
Change.The forward speed of car body, and by program control.Speed will meet the following conditions：Broom turns left, turns right before swing rod drives
Primary i.e. preceding broom is swept the floor once, that is, broom scans out the length on ground before occurring this time, when sweeping the floor again next time, must repeat to sweep
Last time scans out the certain distance in section, i.e., every time before broom section of sweeping the floor the last time will have been swept section and reserve certain length
Overlap, that is, duplicate block.Under normal circumstances, by preceding broom per minute sweep the floor number be multiplied by before broom length product obtained by it is long
One half-distance of degree is exactly the distance of car body walking per minute, and here it is speed, also can be converted into how much rice per second.It can also adopt
With the intermittent advance of car body.4/5ths of broom length before car body advances repeat overlap joint cleaning 1/5th length of area every time
It is sufficient.But it is general to want more convenient and efficient using working continuously.
