Description
Technical field
The utility model relates to the cement concrete production equipment, particularly a kind of planetary vertical-shaft concrete mixer.
Background technology
Available coagulation soil vertical shaft mixer has and adopts single motor reduction gearbox, also has to adopt the multiple electric motors reduction box, and motor reduction gearbox places the mixer top.If adopt the separate unit motor reduction gearbox, because the radius from the center of top to the outer is long, need bigger moment could drive mixer, obviously the layout of separate unit motor reduction gearbox is unreasonable.If adopt the multiple electric motors reduction box, that will see how it arranges.
In addition, adopt single motor to reset under the situation that mixer is fully loaded with, for example stirring capacity is 2m
3Concrete mixer need cause its single power of motor big up to the motor power of 75kW, power consumption is big, has raised the production cost that concrete stirs thus.
During concrete mixer work, because the separate unit motor reduction gearbox is positioned at mixer centre top, when materials such as mixer input sandstone, cement, can only throw in by the other subregion of slave, trouble so feeds intake, two need the long period to mix and stir, and make mixing time longer thus, have expended electric energy.
The utility model content
Task of the present utility model provides a kind of improved planetary vertical-shaft concrete mixer, and the motor reduction gearbox layout that it has solved the existing concrete mixer is unreasonable, power of motor is big, power consumption is big, concrete stirs the production cost problem of higher.
Technical solution of the present utility model is as follows:
A kind of planetary vertical-shaft concrete mixer, it comprises the motor reduction gearbox that is placed in the mixer top, and the central charging device that has central dog-house that is provided with in mixer center of top zone, the slew gear of motor reduction gearbox is connected with mixing arm, mixing arm is installed in the stir chamber together with stirring shovel, described motor reduction gearbox is two above motor reduction gearbox, two above motor reduction gearbox are laid in the scope of circle footpath, mixer top with the planet form, and be placed in the outer ring of central dog-house, the slew gear of every motor reduction gearbox is connected with mixing arm with central gear by planetary gear again; Described stirring shovel disposes low level shovel and high-order shovel, and low level shovel and high-order shovel respectively are installed on the mixing arm; The Dump gate of downward unlatching is equipped with in the bottom of described stir chamber.
Planetary vertical-shaft mixer of the present utility model is settled several motor reduction gearbox at the concrete mixer top, the slew gear of every motor reduction gearbox is connected with mixing arm with central gear by planetary gear again, on average transmit by power, because moment is shorter relatively, for example stirring capacity is 2m
3Concrete mixer only need three 22kW motors just can drive fully loaded mixer easily, saved power electric weight 9kW thus, saved power consumption, reduced the production cost of concrete stirring.
Mixer of the present utility model is provided with central charging device, central authorities' charging device is arranged on the center of top zone of concrete mixer, several motor reduction gearbox then are placed in the outer ring of central dog-house, sandstone, after materials such as cement are knocked down the mixer inner chamber from central dog-house, under stirring action, can immediately spread and be distributed in the mixer intracavity bottom towards periphery, shortened mixing time thus greatly, further saved power consumption, increased the concrete uniformity, help to improve concrete compression strength and stability, and can reduce the production cost that concrete stirs, satisfied the condition that develops energy-saving green machinery.
Description of drawings
Fig. 1 is the structural representation of a kind of planetary vertical-shaft concrete mixer of the present utility model.
Fig. 2 is the front view of Fig. 1 mixer.
Fig. 3 is by vertical view shown in Figure 2.
The specific embodiment
Referring to Fig. 1 to Fig. 3, a kind of planetary vertical-shaft concrete mixer of the present utility model is equipped with slew gear 2, central charging device 3, the mixing arm 4 of motor reduction gearbox 1, motor reduction gearbox and stirs shovel 5.
Two above motor reduction gearbox 1 are placed in the mixer top, and every motor reduction gearbox 1 is connected with its slew gear 2.Central authorities' charging device 3 has central dog-house 31, and central charging device 3 is arranged on mixer center of top zone.The slew gear 2 of motor reduction gearbox is connected with mixing arm 4, and mixing arm 4 is installed in the stir chamber 6 together with stirring shovel 5.
Two above motor reduction gearbox 1 are laid in the scope of circle footpath, mixer top with the planet form, and are placed in the outer ring of central dog-house 31.Motor reduction gearbox 1 cloth in the scope of circle footpath, mixer top is set as two, three or four motor reduction gearbox, and is placed in the outer ring of central dog-house 31.The laying of each motor reduction gearbox 1 is separated by at regular intervals.As shown in Figure 3, motor reduction gearbox 1 cloth in the scope of circle footpath, mixer top is set as four motor reduction gearbox, and each motor reduction gearbox 3 is separated by at regular intervals.The utility model is according to the stirring capacity and configurable one to four motor reduction gearbox of power requirement of mixer.
In conjunction with referring to Fig. 1, motor is placed in the mixer top with upright form, and reduction gear box then is placed in the motor below and is connected with motor output shaft.The slew gear 2 of every motor reduction gearbox 1 is connected with every group of mixing arm 4 with central gear by planetary gear again, and every group of mixing arm 4 can be made up of long mixing arm 41 and short mixing arm 42.The stirring shovel 5 that links to each other with every group of mixing arm 4 disposes low level shovel 51 and high-order shovel 52, and low level shovel 51 and high-order shovel 52 respectively are installed on long mixing arm 41 and the short mixing arm 42.
The long mixing arm 41 of being furnished with low level shovel 51 extends to stir chamber 6 bottoms, and the short mixing arm 42 of being furnished with high-order shovel 52 extends to the top of stir chamber 6 bottoms.The long mixing arm 41 of being furnished with low level shovel 51 slightly is longer than is furnished with high-order 52 the short mixing arm 42 that shovels, and high-order shovel can be forced the upper materials sinking of rolling, and breaks spherical particle, and all materials are all evenly stirred.In the bottom of stir chamber 6 Dump gate of downward unlatching is housed, the concrete after stirring is during in discharging, as long as the downward unlatching of Dump gate can be unsnatched concrete quickly and easily.
