Please refer to Fig. 1, Fig. 1 is arranged at the schematic top plan view of concrete mixer for the utility model provides the centralized lubrication device.
In a kind of embodiment, centralized lubrication device 10 provided by the utility model specifically is positioned at the neutral position of concrete mixer hopper 20 front sides.
The pumping mechanism of concrete mixer shown in the figure is a piston cylinder operator, mainly is made up of hopper 20, two concrete cylinders 30, two concrete pistons, two master cylinders, S shape valve 40, two oscillating oil cylinders 50 and discharge port 60 etc.
Concrete piston is connected with the main oil cylinder piston bar respectively, and reciprocating under the effect of master cylinder hydraulic oil, a cylinder advances, and then another cylinder retreats; The outlet of concrete cylinder 30 is communicated with hopper 20, S shape valve 40 1 termination discharge ports 60, and the other end is connected with swing arm by splined shaft, under the effect of two oscillating oil cylinders 50, can swing.
During the pump concrete material, under two master cylinder effects, the left side concrete piston advances, and the right side concrete piston retreats, and under oscillating oil cylinder 50 effects, S shape valve 40 is communicated with left side concrete cylinder 30 simultaneously, and right side concrete cylinder 30 is communicated with hopper 20.The right side concrete piston retreats like this, just the concrete in the hopper 20 is sucked the right side concrete cylinder, and the left side concrete piston advances, and concrete cylinder 30 inner concrete material in left side is sent into S shape valve 40 pump.
When the right side concrete piston retreats to stroke terminal, trigger reversing arrangement, two master cylinder commutations, two oscillating oil cylinder 50 commutations make S shape valve 40 be communicated with right side concrete cylinder 30 simultaneously, and left side concrete cylinder 30 is communicated with hopper 20, at this moment the right side concrete piston advances, the left side concrete piston retreats, circulation successively, thus realize uninterrupted pumping.
As shown in the figure, two oscillating oil cylinders 50 of S shape valve 40 are symmetrically arranged in hopper 20 front sides among the figure, its oil inlet and oil return pipeline 70 also bilateral symmetry distributes, preceding half section is straight-tube portion 70-1, second half section is flexible pipe part 70-2, hydraulic pipe line between its head is a flexible pipe, by an arm hydraulic return fuel tank, during work, the 70 alternately oil-feeds of two oscillating oil cylinder 50 oil inlet and oil return pipelines, oil return, alternately stretch out, withdraw thereby drive two oscillating oil cylinders 50, drive S shape valve 40 reciprocally swingings, promptly two oscillating oil cylinders 50 are in series on hydraulic circuit.
