5. the mechanical type delivery device that can realize pushing separately according to claim 4, is characterized in that: described axle drive shaft realizes the axial location of overlapping with shift fork by jam nut.
6. the mechanical type delivery device that can realize pushing separately according to claim 4, it is characterized in that: the arranged outside of the bearing of described driven wheel has jam nut, jam nut realizes the axial location of driven wheel and flange sleeve assembly.
7. the mechanical type delivery device that can realize pushing separately according to claim 1, is characterized in that: described flange sleeve assembly comprises flange sleeve, and the rear end axial restraint of flange sleeve connects the bearing of drive rod assembly; The front end of flange sleeve connects the driven shaft of driven shaft assembly by bearing.
8. the mechanical type delivery device that can realize pushing separately according to claim 1, is characterized in that: described driven shaft assembly comprises driven shaft, and driven shaft realizes the axial location with the flange sleeve of flange sleeve assembly by jam nut; Driven shaft can only rotate relative to flange sleeve, but can not axial motion;
The rear end endoporus of driven shaft forms asymmetric splined hole, and asymmetric splined hole matches with the asymmetric spline of axle drive shaft;
The inner of asymmetric splined hole forms the plug helix of a variable diameters, and spiral fluted terminal connects the elongated slot extended vertically; The diameter of plug helix starting point is greater than the diameter of terminal.
9. the mechanical type delivery device that can realize pushing separately according to claim 1, it is characterized in that: described crank rocker assembly comprises rocking bar, the middle part of rocking bar connects one end of connecting rod, one end of the other end connecting crank of connecting rod, and the other end of crank connects the driven shaft of driven shaft assembly; The upper end of rocking bar connects push rod, and the lower end of rocking bar connects pivot shaft assembly;
The transmission being rotated through crank, connecting rod realizable force of driven shaft, makes rocking bar realize swinging for center of gyration with its lower end, drives push rod anterior-posterior translation;
Pivot shaft assembly connects the second oil cylinder; Second oil cylinder can drive the lower end of rocking bar to carry out linear reciprocating motion under the directional tagging of pivot shaft assembly, thus drives push rod anterior-posterior translation, make push rod away from or recover normal operation position.
10. the mechanical type delivery device that can realize pushing separately according to claim 1, is characterized in that: described pivot shaft assembly comprises rocker shaft bearing sleeve, and the anchor shaft supporting moving member is fixedly arranged in rocker shaft bearing sleeve;
The two ends supporting the axis of guide of moving member are flexibly connected body; The axis of guide supporting moving member can seesaw along body;
Pivot shaft assembly leads by supporting the path of motion of moving member to rocking bar lower end.
