Abstract
The utility model discloses a compression garbage truck hydraulic means. This compression garbage truck hydraulic means including being used for operating the hydro -cylinder of push pedal and the hydro -cylinder that is used for operating dustbin turning device, still includes the variable pump, and push plate cylinder and upset hydro -cylinder are connected with the variable pump through the sensitive proportional valve of load respectively, and the variable pump is used for providing hydraulic power, and the sensitive proportional valve of load is used for the corresponding hydro -cylinder of control, carries out quantitative governing output according to load pressure and liquid flow to the variable pump. Each hydro -cylinder load is different, and the sensitive proportional valve of load feeds back to the variable pump according to the load of each hydro -cylinder, applys different pressure and flow to each hydro -cylinder, gross pressure that the sensitive proportional valve of load simultaneously can the control variable pump to power output is made a concerted effort to distribute in the realization, satisfies the load requirement of each hydro -cylinder, real -time demand assignment, furthest's reduction the hydraulic pressure energy consumption.
Description
Technical field
The utility model relates to a kind of compression type garbage truck, especially relates to compression type garbage truck hydraulic efficiency gear.
Background technology
At present, the hydraulic efficiency gear of compression type garbage truck mainly adopts quantitative system, and namely hydraulic system pressure, flow limit all, and actual loading has nothing to do.Prior art Problems existing is, this system adopts fix-displacement pump, proportional valve group, can not regulate in real time, and no matter how actual operating mode changes, and this hydraulic efficiency pressure system all works under the parameter set, and shortcoming is exactly that hydraulic resources compares waste, and system energy consumption is larger.
Summary of the invention
The purpose of this utility model is the deficiency existed for prior art, provides the compression type garbage truck hydraulic efficiency gear of a kind of pressure that can export according to the different adjustment hydraulic pressure of load and hydraulic flow.
For achieving the above object, the technical scheme that the utility model compression type garbage truck hydraulic efficiency gear adopts is:,
A kind of compression type garbage truck hydraulic efficiency gear, comprise the oil cylinder for operating push pedal and the oil cylinder for operating overturn of trash bin device, also comprise controllable capacity pump, push pedal oil cylinder is connected with controllable capacity pump respectively by load-sensitive apportioning valve with overturning oil cylinder, controllable capacity pump is used for providing hydraulic power, load-sensitive apportioning valve, for controlling corresponding oil cylinder, carries out variable regulation output according to load pressure and fluid flow to controllable capacity pump.
Also comprise the oil cylinder for operating scraper plate, described oil cylinder is connected with controllable capacity pump by load-sensitive apportioning valve.
Also comprise the oil cylinder for operating slide plate, described oil cylinder is connected with controllable capacity pump by load-sensitive apportioning valve.
Also comprise the oil cylinder for lifting rubbish container, described oil cylinder is connected with controllable capacity pump by load-sensitive apportioning valve.
The fluid output port of described controllable capacity pump or fluid input port are provided with the radiator for liquid cooling.
The utility model compared with prior art, has the following advantages:
Power is provided to hydraulic efficiency gear by controllable capacity pump, again by load-sensitive proportional valve control hydraulic output device, achieve the motion of each mechanism of compression type garbage truck, load pressure of the present utility model, flow pass through delivery rate and the pressure of load-sensitive apportioning valve variable regulated variable pump.Compression type garbage truck hydraulic efficiency gear pressure characteristics of the present utility model, when compression type garbage truck collects different rubbish respectively, the total weight of sewage disposer has larger difference, when collecting lighter sewage disposer, load is light, and the automatic regulated variable pump of load-sensitive apportioning valve exports, thus reduces energy consumption.The flow characteristic of compression type garbage truck hydraulic efficiency gear of the present utility model, flow needed for each oil cylinder is different, the oil cylinder of push pedal needs flow larger, and the oil cylinder of turning device needs flow less, now feed back to controllable capacity pump by load-sensitive apportioning valve, automatically the flow needed for each oil cylinder is controlled, the requirement meeting each device of intelligence.Fluid pressure in compression type garbage truck hydraulic efficiency gear of the present utility model, flow distribute automatically, and energy saving of system obtains great raising.
Accompanying drawing explanation
Fig. 1 is the structural representation of compression type garbage truck hydraulic efficiency gear.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
A kind of compression type garbage truck hydraulic efficiency gear as shown in Figure 1, comprise controllable capacity pump 1 and load-sensitive apportioning valve 2, also comprise the oil cylinder 3 for operating push pedal, for operate slide plate oil cylinder 4, for operating the oil cylinder 5 of scraper plate and the oil cylinder 6 for operating overturn of trash bin device, these oil cylinders are connected with controllable capacity pump 1 by load-sensitive apportioning valve 2, the fluid input port of controllable capacity pump is connected with hydraulic reservoir 8, and the fluid input port of hydraulic reservoir 8 is connected with the radiator 7 for liquid cooling.
Each oil cylinder load is different, load-sensitive apportioning valve according to the load feedback of each oil cylinder to controllable capacity pump, different pressure and flow are applied to each oil cylinder, simultaneously load-sensitive apportioning valve can the gross pressure of control variable pump, to realize making a concerted effort to distribute power stage, meet the load request of each oil cylinder, distribute according to need in real time, reduce hydraulic pressure energy consumption to greatest extent.
