Description of drawings
Fig. 1 is the utility model embodiment schematic diagram.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is further described.
A kind of concrete mixer described in the utility model, comprise, the hydraulically extensible axle 12 (with reference to figure 1) that is used for the lifting of control charging barrel, the hydraulic system that is used for control hydraulically extensible axle 12, the two ends of the fluid passage of described hydraulically extensible axle 12 all are connected with hydraulic system, form a fluid loop, described hydraulically extensible axle 12 front ends link to each other with charging barrel.
With reference to figure 1, be the utility model embodiment schematic diagram.
Described 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, are provided with the movement that wheel is convenient to mixer on the bearing support.
Banked direction control valves 11 comprises at least three imports, and three outlets are mainly used in controlling oily flow direction; Wherein first via import and outlet, as mentioned above, described oil cylinder is connected with the first import of described banked direction control valves 11 by oil pump 5, gets back to described oil cylinder through the first outlet; Two operating grips are arranged respectively on the banked direction control valves 11, control respectively the second the road and Third Road import and outlet, the second tunnel rotation direction that is used for the control agitator wherein, Third Road is used for the lifting of control charging barrel.
The second import of described banked direction control valves 11 is connected with oil cylinder by oil pump 5, and second exports and be connected to oil cylinder by hydraulic motor 10, and hydraulic motor 10 passes through connecting axle 9 is connected connection with gear wheel, and gear wheel 7 is connected connection with the agitator gear.Change the second road oil circuit direction of importing and exporting of banked direction control valves 11 by the operating grip of banked direction control valves 11, the oil circuit direction that namely changes by 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 so that, when hydraulic motor 10 forward, agitator carries out spice, when it reversed, agitator carried out discharging.
The triple feed inlet of banked direction control valves 11 is connected with oil cylinder by oil pump 5, and the 3rd outlet is connected to oil cylinder by the fluid passage of hydraulically extensible axle 12, and the front end of hydraulically extensible axle 12 connects charging barrel.When by operation banked direction control valves 11, change the oil circuit direction of the Third Road import and export of banked direction control valves 11, namely change oil circuit by the direction of hydraulically extensible axle 12, when oil flows (with reference to figure 1) from the bottom up along hydraulically extensible axle 12, the action that stretches of this telescopic shaft 12, when oil flows (with reference to figure 1) from top to bottom along hydraulically extensible axle 12, this telescopic shaft 12 carries out contractive action, thereby control hydraulically extensible axle 12 is flexible, by rising and the decline of stretching to promote charging barrel of hydraulically extensible axle 12.Because this pressure is even variation, thereby the charging barrel of electing by hydraulically extensible axle 12 is also at the uniform velocity improved or descends.
