Abstract
The invention relates to the field of concrete mixers and particularly relates to a low-noise double-shaft concrete mixer. The double-shaft concrete mixer comprises a mixing drum and two mixing shafts, wherein the two mixing shafts are respectively in transmission connection with a speed reducer, the two speed reducers are respectively provided with input shafts and output shafts, which are vertical to each other, the output rotation directions of the output shafts of the speed reducers are opposite, and the input shafts of the two speed reducers are in coaxial transmission connection through a shaft coupler; a synchronous gear on the conventional product is unnecessary, so that the noise generated by the engagement of the synchronous gear is eliminated, and the problem of high noise of the existing concrete mixer during the working process is solved; besides, the synchronous gear on the conventional product is omitted, so that the production cost of the mixer is reduced; and therefore, the low-noise double-shaft concrete mixer provided by the invention has the advantages that is the problem of high noise of the conventional concrete mixer during the working process is solved, but also the production cost of the double-shaft concrete mixer is lowered.
Description
Technical field
The present invention relates to the concrete mixer field, especially a kind of double-axle concrete-mixer of low noise.
Background technology
Concrete mixer is widely used in building and the construction of road and bridge field, can be divided into single-shaft stirring machine and biaxial rneader according to the quantity of its shaft.Wherein biaxial rneader comprises mixing drum and two shafts, mixing drum comprises two end plates of one in front and one in back interval setting and is connected to two coaming plates between the end plate, coaming plate surrounds a stir storehouse with two end plates, the right setting of a first from left that two shafts are parallel to each other and by bearing assemble on two end plates, during work, require two shafts to rotate synchronously and switched in opposite, in the present product, synchronous backward operation between two shafts realizes by a pair of synchromesh gear, and synchromesh gear directly is in transmission connection by gear and the cycloid speed reducer of correspondence, therefore have following defective: 1) engagement of synchromesh gear produces huge noise and vibration, the physical and mental health that endangers the operator has on the one hand also been accelerated the damage of mixer on the other hand; 2) owing to be to adopt the form of gear engagement to be connected with speed reducer drive, therefore without overload protection function, in the mixer running, if there are large particle diameter building stones to cause agitating device stuck or load is overweight in the mixer, will cause reductor to damage or motor burns out; 3) processing technology of synchromesh gear is comparatively complicated, and this has directly caused the reduction to the manufacturing efficient of mixer; 4) in order to realize the gear drive between reductor and the shaft, the output shaft of motor is all parallel to each other with shaft, and this has then directly increased required installing space, has increased the volume of mixer integral body.
Summary of the invention
The object of the present invention is to provide a kind of double-axle concrete-mixer of low noise, to solve the noise large problem of existing concrete mixer when working.
In order to address the above problem, the double-axle concrete-mixer of low noise of the present invention is by the following technical solutions: the double-axle concrete-mixer of low noise, comprise mixing drum and two shafts, mixing drum comprises coaming plate and two end plates, two shafts are connected with a reductor separately, the output direction of rotation that described two reductors have mutually perpendicular power shaft and output shaft and the output shaft of the two separately is opposite, and the power shaft of two reductors links together by the shaft coupling coaxial transmission.
All be equipped with belt pulley on the power shaft of each reductor and be connected with motor by belt transmission.
One the outside of the input of close shaft is provided with gusset in two end plates of mixing drum, and described motor and reductor all fixedly are assemblied on this end plate.
Described motor is assemblied on the corresponding end plate by the motor cabinet of correspondence, one end of described motor cabinet is hinged on the corresponding end plate with the parallel jointed shaft of the power shaft of reductor by one, the other end is free end, also is provided with the strut that is locked in the diverse location place for the free end with motor cabinet on the end plate.
Described reductor is planetary reducer.
Because the double-axle concrete-mixer of low noise of the present invention is connected with a reductor separately at two shaft, and the output direction of rotation that described two reductors have mutually perpendicular power shaft and output shaft and the output shaft of the two separately is opposite, and the power shaft of two reductors links together by the shaft coupling coaxial transmission; Therefore, the synchronous rotary of two shafts when work can be realized by described shaft coupling, the reverse rotation of two shafts can realize by described reductor, do not need to adopt again the synchromesh gear on the traditional product, thereby eliminated the noise that produces owing to the synchromesh gear engagement, solved the noise large problem of existing concrete mixer when work; In addition, owing to abandoned the synchromesh gear on the traditional product, therefore also shorten the technology chain that mixer is produced, improved the production efficiency to the assembling manufacturing of mixer, reduced the production cost to mixer; The double-axle concrete-mixer that this shows low noise of the present invention has not only solved the noise large problem of conventional concrete mixer when work, and has reduced the production cost of double-axle concrete-mixer.
Further, be connected the overload protection function that to realize mixer by belt transmission between the power shaft that makes reductor and the motor, can be stuck or skidding occurs when overweight in load at shaft, unlikely damage reductor or burn out motor, in addition, adopt the bel-drivenn mode also so that motor shaft can and reductor shaft between parallel to each other, thereby change the installation position of motor, reduce the required space of mounted motor, and then reduce the volume of mixer integral body; Gusset plays the effect of reinforcing end plate, motor and speed reducer all is assemblied in the volume that has further reduced mixer integral body on the end plate; Motor cabinet is installed with the multiposition of having realized motor that cooperates between the strut, thus the elasticity that can regulate easily belt, the Fast Installation of realization belt; Planetary reducer has increased driving force than cycloid speed reducer.
