The invention provides a floating
connection control system and method for a double-pull-rod sliding block movable bale breaker. An oil inlet of a hydraulic
oil pump is connected with a hydraulic
oil tank, an oil outlet of the hydraulic
oil pump is connected with a port P of an electromagnetic overflow valve set, and the electromagnetic overflow valve set is connected with a port P of a
reversing valve set after passing through an internal one-way valve; the electromagnetic overflow valve group is connected with a filter after being converged with a T port of the
reversing valve group; the filter is communicated with a hydraulic
oil tank; a first
reversing valve of the reversing valve group is connected with
piston cavities of the first clamping oil cylinder and the second clamping oil cylinder through a first
hydraulic control one-way valve and a first energy accumulator group; a second reversing valve of the reversing valve group is connected with
piston cavities of the third clamping oil cylinder and the fourth clamping oil cylinder through a second
hydraulic control one-way valve and a second energy accumulator group; a third reversing valve of the reversing valve group is connected with the unpacking oil cylinder group through the control valve group; and the pressure
transmitter group is used for detecting the pressure of the
system. By means of the
system, real-time clamping of the multiple clamping oil cylinders of the double-pull-rod sliding block moving type bale breaker under the
constant pressure can be achieved.
