Background technology
Belt tension in the existing concrete mixer drive unit adopts mostly and is rigidly connected, its drive mechanism is mainly by motor, motor cabinet, motor pulley, the V band, the reductor belt pulley, formations such as reductor, motor cabinet is fastened on the frame and can not regulates, cause the distance between the motor and speed reducer unadjustable, there is following shortcoming 1 in it: when mixer is worked, owing to be difficult to find out the tensioning state of belt, and can't drive unit in time be adjusted, the phenomenon of belt creep takes place sometimes, cause belt damage to be accelerated, can't meet the quality requirement of ready-mixed concrete; 2: be rigidly connected owing to the belt in the drive unit all adopts,, when starting, cause belt stressed easily than causing fracture greatly if belt is aging.
Summary of the invention
The utility model provides a kind of drive unit of concrete mixer at the defective that prior art exists, and can solve the problem of belt creep, prolongs the service life of mixer belt, improves mixer to concrete mixing quality.
For this reason, the utility model is taked following technical scheme: mix earth mixer drive unit, comprise frame, frame is provided with the motor cabinet of horizontal, motor is installed on it, on the output shaft of motor motor pulley is installed, the outside, below that it is characterized in that described motor cabinet is provided with reductor, the reductor belt pulley is installed on the output shaft of reductor, described motor pulley links to each other by belt with the reductor belt pulley, the outboard end and the frame of described motor cabinet are coupling, and its medial end is provided with the perpendicular pressure buffer device of putting, and this pressure buffer device upper and lower side links to each other with frame with motor cabinet respectively.When driving mechanism is worked, can find out the belt tension state by the amount of tension of buffer unit, again the position of motor cabinet is adjusted, change the distance between motor pulley and the reductor belt pulley, thereby the tensile force of control belt, avoid the generation of belt creep phenomenon, prolong the service life of belt, improve the performance of concrete mixer drive unit.Buffer unit can also be alleviated the excessive belt Problem of Failure that causes of the instantaneous pulling force that causes because of startup.
Described pressure buffer device comprises spring pull bar, nut, spring, adjustment plain cushion, supporting base, described motor cabinet is provided with through hole, the upper end of described spring pull bar is passed through hole, adjustment plain cushion and nut and is joined, its lower end and spring upper end links to each other, and the lower end of spring links to each other with supporting base on being fixed in frame.Unscrew or fastening nut adjustable joint motor inner side end and supporting base between distance, thereby regulate distance between motor and reductor, adjust the tension force of belt.
The bottom of described motor cabinet links to each other with frame by screw bolt and nut, and the bottom of motor cabinet also can link to each other with frame with guide by bearing pin.Be convenient to regulate by a small margin the upper-lower position of motor cabinet, preventing that the pulling force of belt was excessive when motor cabinet from carry starting owing to band causes that the motor cabinet amplitude is excessive, in the time of also preventing simultaneously motor cabinet owing to the belt complete rupture, cause motor cabinet because of gravity or other reasons rotation, cause mechanical accident and run into reductor.
Described frame is provided with symmetrical two motor and speed reducers, and the output shaft of described two reductors joins by shaft coupling.The effect of shaft coupling is the synchronous rotation of forcing two electric machine main shafts, avoids the difference of the difference of two motors or two motor instantaneous startings and causes that two shafts are asynchronous and cause the mixer quality problems.
The outboard end of described motor cabinet is connected by bearing pin with frame, and motor cabinet can rotate around bearing pin, changes distance between motor pulley and the reductor belt pulley thus, thus the tensile force of control belt.
The beneficial effects of the utility model are embodied in: 1. increase buffer unit between motor cabinet and frame, not only can alleviate the instantaneous pulling force that causes because of startup and cross ambassador's belt Problem of Failure, can also find out the belt tension state by the amount of tension of buffer unit.2. adopt between motor cabinet and the frame and be coupling, rotatable support rotates the distance that changes between motor pulley and the reductor belt pulley around bearing pin, thereby the tensile force of control belt, avoid the generation of belt creep phenomenon, prolong the service life of belt, improve the performance of concrete mixer drive unit.
