Abstract
The utility model discloses a concrete mixer which comprises a hydraulic telescopic shaft used for controlling a charging barrel to ascend and descend and a hydraulic system used for controlling the hydraulic telescopic shaft, wherein two ends of a liquid passage of the hydraulic telescopic shaft are connected with the hydraulic system, so as to form a liquid loop; and the front end of the hydraulic telescopic shaft is connected with the charging barrel. Compared with a mixer which commonly uses a steel wire traction mechanism, the mixer adopting the hydraulic system has the advantages that the charging operation is more stable, the charging barrel can ascend and descend stably, and the safety of transportation personnel at a discharge port is ensured.
Description
Technical field
The utility model relates to the Mixing Machine technical field, refers to especially a kind of concrete mixer.
Background technology
Concrete mixer is cement, sandstone aggregate and water mixing and mixes the machinery of making concrete mixture.Mainly formed by mixing drum, reinforced and shedding mechanism, water system, prime mover, transmission mechanism, frame and supporting arrangement etc.
The feeding structure of traditional concrete mixer is to adopt steel wire traction, that is, the employing motor, lifts charging barrel as hitch structure as the power steel wire during rising, and material is poured into mixing drum; And when descending, adopt the device of similar brake, slowly charging barrel is put down.The shortcoming of this structure is: the wearing and tearing of (1) steel wire can make charging barrel fall down suddenly; (2) when descending, owing to being to adopt manual mode, human factor is very large on the equipment impact, in case misoperation can make charging barrel fall down, the conveying people of discharging opening is damaged.
The utility model content
In view of this, the purpose of this utility model is to propose a kind of concrete mixer, and it adopts the mode of automatic control, and slow lifting charging barrel, has ensured personal security.
A kind of concrete mixer that provides based on above-mentioned purpose the utility model, comprise, the hydraulically extensible axle that is used for the lifting of control charging barrel, the hydraulic system that is used for control hydraulically extensible axle, the two ends of the fluid passage of described hydraulically extensible axle all are connected with hydraulic system, form a fluid loop, described hydraulically extensible axle front end links to each other with charging barrel.
Further, described hydraulic system comprises banked direction control valves, oil pump, oil cylinder, and described oil pump connects described oil cylinder by oil pipe, and an end of described oil cylinder connects described banked direction control valves, and this banked direction control valves is connected with oil pump by described hydraulically extensible axle.
Optionally, described hydraulic system adopts handle or its switch of button control.
Better, described mixer floor installation is useful on the wheel of mixer position.
Further, be connected with oil filter on the described oil cylinder, be connected with oil filter on the described oil pump.
Can find out from above, a kind of concrete mixer that the utility model provides adopts hydraulic system to substitute the steel wire haulage gear as feeding transmission mechanism, realizes steady lifting charging barrel, guarantee the material loading working stability, and ensured the safety of the conveying people of discharging opening.
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 that the utility model provides, comprise, the hydraulically extensible axle 15 (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 15, the two ends of the fluid passage of described hydraulically extensible axle 15 all are connected with hydraulic system, form a fluid loop, described hydraulically extensible axle 15 front ends link to each other with charging barrel.
Be the utility model embodiment schematic diagram with reference to figure 1.
Described concrete mixer comprises agitator 1, main motor 2, belt 3, drive shaft 4, gear-box 5, agitator gear 6, gear wheel 7, oil pump 8, banked direction control valves 9, flowline 10, oil inlet pipe 11, oil cylinder 12, auxiliary motor 13, stock shelf support bar 14, hydraulically extensible axle 15.
All parts all are installed on the bottom supporting frame, are useful on the wheel of mixer on the bearing support.
Hydraulic system comprises: auxiliary motor 13, banked direction control valves 9, oil pump 8, flowline 10, oil inlet pipe 11, oil cylinder 12, hydraulically extensible axle 15.Auxiliary motor 13 is connected connection with oil pump, oil pump 8 one ends connect oil cylinder 12 by flowline 10, oil cylinder 12 another termination banked direction control valves 9, fluid passage one end that banked direction control valves 9 is connected with the hydraulically extensible axle by flowline 10 connects, the fluid passage other end of hydraulically extensible axle 15 is connected 8 with oil pump, that is, this banked direction control valves 9 is connected with oil pump (8) by described hydraulically extensible axle 15, thereby forms a loop.
Control the flow direction of oil by banked direction control valves 9, when oil flows (with reference to figure 1) from the bottom up along hydraulically extensible axle 15, the action that stretches of this telescopic shaft 15, when oil flows (with reference to figure 1) from top to bottom along hydraulically extensible axle 15, this telescopic shaft 15 carries out contractive action, thereby controls the flexible of hydraulically extensible axle 15, because the front end of described hydraulically extensible axle 15 connects charging barrel, therefore, then can be by rising and the decline of stretching to promote charging barrel of hydraulically extensible axle 15.
Adopted the concrete mixer of above-mentioned hydraulic system, lifting by the HYDRAULIC CONTROL SYSTEM charging barrel and putting down, owing to adopt hydraulic system, when rising, only need to press starting handle, make hydraulic work system, charging barrel will be raised, and will automatically stop when the longest to hydraulically extensible axle 15, when transferring, owing to need to the liquid on the hydraulically extensible axle 15 be extruded just and can transfer, by the size of controlled pressure, can realize slowly transferring charging barrel.
Adopt the mixer of this hydraulic system than the material loading more stable work of the mixer of normal operation steel wire traction mechanism, realized steady lifting charging barrel, and ensured the safety of the conveying people of discharging opening.
And, adopt this hydraulic system after, the material loading bottom supporting structure of described mixer will no longer need position limiting structure, not need manually to go brake or charging barrel is descended.
It is pointed out that described 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 described mixer floor installation is used for the wheel of mixer position is in order to make things convenient for the movement of mixer, also wheel can not to be installed, needing with the client fully.
In addition, but equal junctor oil rectifier on described oil cylinder and the oil pump, so that it is worked better.
Those of ordinary skill in the field are to be understood that: the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle; any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
