In another embodiment, said battery is detachable.
In another embodiment, also be connected with oil filter on the said oil pump.
Saidly can find out from top; A kind of concrete mixer provided by the invention; Concrete mixer also can operate as normal when having guaranteed not have power equipment; And its material loading structure utilizes hydraulic system to substitute steel wire traction as haulage gear, thereby realizes going up lifting and putting down of charging basket, has ensured personal security.
Description of drawings
Fig. 1 is an embodiment of the invention sketch map.
The specific embodiment
For making the object of the invention, technical scheme and advantage clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, to further explain of the present invention.
A kind of concrete mixer of the present invention; Comprise; Be used to control the hydraulically extensible axle 12 (with reference to figure 1) that charging basket goes up and down, be used to control the hydraulic system of hydraulically extensible axle 12, the two ends of the fluid passage of said hydraulically extensible axle 12 all are connected with hydraulic system; Form a fluid loop, said hydraulically extensible axle 12 front ends link to each other with last charging basket.
With reference to figure 1, be embodiment of the invention sketch map.
Said concrete mixer comprises: diesel engine 1, starter motor 2, belt 3, water system 4, oil pump 5, agitator gear 6, gear wheel 7, battery 8, connecting axle 9, hydraulic motor 10, banked direction control valves 11, hydraulically extensible axle 12.
All parts of mixer all are installed on the bearing support, and bearing support is provided with wheel and is convenient to moving of mixer.
Banked direction control valves 11 comprises at least three imports, and three outlets are mainly used in the oily flow direction of control; Wherein first via import and outlet, as stated, said oil cylinder is connected with first import of said banked direction control valves 11 through oil pump 5, gets back to said oil cylinder through first outlet; Two operating grips are arranged respectively on the banked direction control valves 11, control respectively the second the tunnel with Third Road import and outlet, wherein the second the tunnel be used to control agitator rotation direction, Third Road is used to control the up-down of charging basket.
Second import of said banked direction control valves 11 is connected with oil cylinder through oil pump 5, and second outlet is connected to oil cylinder through hydraulic motor 10, and hydraulic motor 10 is connected with gear wheel 7 through connecting axle 9, and gear wheel 7 is connected with agitator gear 6.Operating grip through banked direction control valves 11 changes the oil circuit direction that the second road of banked direction control valves 11 is imported and exported, and the oil circuit direction that promptly changes through hydraulic motor 10 rotates and reverse hydraulic motor 10, when hydraulic motor 10 rotates; Gear wheel 7 rotates thereupon and drives agitator gear 6 and rotates; Final feasible, when hydraulic motor 10 was just changeing, agitator carried out spice; When it reversed, agitator carried out discharging.
The triple feed inlet of banked direction control valves 11 is connected with oil cylinder through oil pump 5, and the 3rd outlet is connected to oil cylinder through the fluid passage of hydraulically extensible axle 12, and the front end of hydraulically extensible axle 12 connects upward charging basket.When through operation banked direction control valves 11, change the oil circuit direction of the Third Road import and export of banked direction control valves 11, promptly change the direction of oil circuit through hydraulically extensible axle 12; When oil when hydraulically extensible axle 12 flows (with reference to figure 1) from the bottom up; The action that stretches of this telescopic shaft 12, when oil when hydraulically extensible axle 12 flows (with reference to figure 1) from top to bottom, this telescopic shaft 12 carries out contractive action; Thereby control hydraulically extensible axle 12 is flexible, promotes the rising and the decline of charging basket through stretching of hydraulically extensible axle 12.Because this pressure is even variation, thereby the last charging basket of electing through hydraulically extensible axle 12 is also at the uniform velocity improved or descends.
Adopted the concrete mixer of above-mentioned hydraulic system, the lifting through charging basket on the HYDRAULIC CONTROL SYSTEM and putting down is owing to adopt hydraulic system; When rising, only need press starting handle, make hydraulic work system; Last charging basket will be raised, and will stop automatically when the longest to hydraulically extensible axle 12, when transferring; Owing to need extrude the liquid on the hydraulically extensible axle 12 just and can transfer,, can realize slowly transferring charging basket through the size of controlled pressure.
Adopt the mixer of this hydraulic system more generally to use the material loading more stable work of the mixer of steel wire traction mechanism, realized charging basket in the steady up-down, and ensured the safety of the conveying people of discharging opening; And its dynamical system has adopted the diesel engine power supply, has guaranteed that said mixer also can operate as normal in the remote mountain areas that does not have power equipment.
And, adopt this hydraulic system after, the material loading bottom supporting structure of said mixer will no longer need position limiting structure, not need manually to go brake or make charging basket decline.
It is pointed out that said hydraulic system can select to adopt handle or its switch of button control, and the mode of operation that other those skilled in the art can expect realizes switch.
The purpose that said mixer base is installed the wheel that is used for mobile mixer position is the mobile of mixer for ease, also wheel can be installed, needs with the client fully.
In addition, but equal junctor oil rectifier on said oil cylinder and the oil pump, so that it is worked better; Described battery is detachable, is convenient to it and charges whenever and wherever possible.
The those of ordinary skill in affiliated field is to be understood that: the above is merely specific embodiment of the present invention; Be not limited to the present invention; All within spirit of the present invention and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
