Embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
Figure 1 shows that the present embodiment thresher hydraulic circuit.Thresher drum main shaft is connected with hydraulic motor 5 main shaft by shaft coupling.Regulate the opening of flow speed control valve 3, the different pressure oil flows entering hydraulic motor 5 can be obtained, make hydraulic motor obtain different rotating speeds, thus realize the stepless speed regulation of threshing cylinder.
When thresher blocks, hydraulic system pressure increases, and when pressure reaches the setting pressure of pressure switch (YJ) 4, YJ circuit ON (see figure 2), three-position four-way valve solenoid directional control valve 2 switches oil circuit, and hydraulic motor 5 and threshing cylinder reversion, get rid of clogging.
Under extreme case, thresher blocking cannot be got rid of, and system pressure continues to raise, and when pressure reaches the setting pressure of overflow valve 6, off-load opened by overflow valve 6, and system pressure reduces, and reaches the object of protection Hydraulic Power Transmission System.
Hydraulic pump 1 by engine or motor driven, for system provides pressure oil.
