Abstract

Currently, in the hydraulic concrete mixer produced by nation, the steel cable needs to wind around a plurality of guiding pulley wheels. Because the forward and reverse directions are bending, the hydraulic concrete mixer produced by nation has large resistance and short life. Furthermore, the mixing barrel of the hydraulic concrete mixer produced by nation uses an oil cylinder for turning over, which leads the uneven stress. The utility model makes a pulley-block box for charging oil-cylinder installed beside the orbit for repairing conveniently. Simultaneously, the steel cable has good winding direction, which extends the service life. The mixing barrel for turning over adopts two oil cylinder to motivate, which makes the supporting forces of the mixing barrel and two end shafts are homogeneous and small. The travel of a charging hopper and the travel of the mixing barrel have automatic position, automatic water supply, stable working and high productivity. The utility model can be extensively used for the concrete mixing in the building construction.

Description

Hydraulic charging & discharging concrete mixer

The concrete mixer of hydraulic pressure material loading discharging belongs to the building machinery field.

Mixer major part of domestic production at present be machine driving, complex structure not only, and manipulation is inconvenient, and performance such as stroke limit is also very poor.For the concrete mixer of hydraulic pressure material loading discharging, though domestic have, result of use is undesirable.The patent No.: 87200141, material oil cylinder assembly pulley is installed in below the frame on it, steel wire rope will be walked around on the framework platform, behind a plurality of up and down leading blocks, promote hopper again, the shortcoming of this structure is, inconvenient maintenance, steel wire has the both forward and reverse directions bending, has not only increased resistance, and has seriously shortened the life-span of steel wire rope, this patent shedding mechanism only is provided with a hydraulic oil cylinder driving in mixing drum one side simultaneously, not only rod end coupling is stressed big, fragile when working like this, and makes the bearing discontinuity at shaft two ends, a shaft strength near oil cylinder is very big, and mixing drum is turned round during work.In addition, after material enters mixing drum, need the artificial feedwater in good time of paying close attention to, make troubles to operation.

The purpose of this utility model be to design a kind of rational in infrastructure, stressed evenly, the automatic ration feedwater, the concrete mixer of the easy to maintenance and novel hydraulic material loading discharging that prolong service life.

For achieving the above object, the utility model is contained in the oil cylinder assembly pulley in the box of frame top sealing entirely, with parallel track, the bending direction unanimity of the few and steel wire rope of the leading block of steel wire rope process like this, resistance is little, life-span is long, open loam cake and can expose entirely, be convenient to maintenance, the travel switch of control water pump is housed in the box simultaneously, when elevating hopper is raised to the mixing drum position in tube during discharging, movable pulley just moves to the box end and touches travel switch, can handle water pump automatically, supplies water in mixing drum, on shedding mechanism, the utility model is respectively installed an oil cylinder at the mixing drum two ends, evenly promote the mixing drum discharging of tumbling during work, and tube is not turned round, two end bearings are stressed little, and are stressed even.

Be described in detail and provide optimum implementation below with reference to accompanying drawing.

The utility model mainly contains frame, feed mechanism, shedding mechanism three parts composition.

Accompanying drawing one is a front view of the present utility model;

Accompanying drawing two is side views of the present utility model;

Accompanying drawing three is fundamental diagrams of the utility model feed mechanism;

Accompanying drawing four is front views of the utility model shedding mechanism;

Accompanying drawing five is side views of the utility model shedding mechanism;

Feed mechanism is seen accompanying drawing one, accompanying drawing two, by oil cylinder assembly pulley box 1, compositions such as hopper 2 and pulley 3, oil cylinder assembly pulley box is installed in the frame top, other and the parallel track of material loading track, its operation principle is seen figure three, and material loading hydraulic cylinder 6 is housed in the box, the oil cylinder afterbody is equipped with fixed pulley group 7, and fix with oil cylinder assembly pulley box, the oil cylinder piston boom end is equipped with from running block 8, and steel wire rope is on fixed pulley and movable pulley, last pass-out is through leading block 3 on the frame, be fixed on then on the hopper 2, this is a kind of speedup assembly pulley that increases stroke, when the oil cylinder piston bar stretches out, assembly pulley is apart from elongation, steel cord ends just promotes hopper, because the oil cylinder piston throw of lever is certain, so the stroke of hopper is also certain.In the assembly pulley box, also arrange a travel switch 9, supply water in order to automatic control, when hopper rises to the mixing drum position in tube during discharging, movable pulley 8 just moves to the box end and touches travel switch 9, can handle automatically water pump in mixing drum quantitatively, automatic water-supply.

Shedding mechanism is seen accompanying drawing four, accompanying drawing five, and the utility model adopts two oil cylinders 4 in mixing drum two side drives, when piston rod movement, can promote mixing drum, finishes discharging, and is certain because of oil cylinder stroke, therefore guarantees mixing drum certain angle of at every turn tumbling.

Its working procedure is: after elevating hopper is filled, move handle 5, hopper 2 promotes automatically, rise to discharge position during preceding 0.5～1 second, movable pulley 8 touches travel switch 9, supplies water in advance in the trend mixing drum, aggregate drops in the mixing drum then, mixing drum begins to stir, and is stirred to certain hour, moves handle 10, the piston rod of oil cylinder promotes mixing drum and tumbles, finish discharging, dump cylinder of the present utility model is if be equipped with buffer unit, can avoid mixing drum tumble and the impact when resetting better.

The utlity model has following advantage:

1. adopt hydraulic charging ﹠ discharging simple structure, stroke limit better performances;

2. totally-enclosed owing to upper material oil cylinder assembly pulley box, and be installed in frame top and material loading parallel track, outward appearance U.S. opens loam cake and entirely can expose, easy access, and the steel wire rope bending direction is consistent, and resistance is little, and the life-span is long, and automatic water-supply.

3. discharging is because respectively installing an oil cylinder at the mixing drum two ends, and the two ends Bearing Seat Force is even during work, and tube is not turned round, and has obvious superiority than prior art.

When the utility model can be widely used in construction to concrete stirring.

Claims

1, a kind of fluid pressure type concrete mixer of forming by frame, feed mechanism, shedding mechanism, it is characterized in that: feed mechanism has an oil cylinder assembly pulley box 1 that promotes hopper to be installed in by the material loading track of frame top, with the material loading parallel track, shedding mechanism adopts two oil cylinders 4 in mixing drum two side drives.

2, fluid pressure type concrete mixer according to claim 1 is characterized in that: a travel switch 9 is housed in the box, puts in place when hopper 2 promotes, movable pulley 8 moves to the box end can touch travel switch 9.
