Description

Concrete stirrer

The utility model is relevant with concrete central mix plant, and is especially relevant with vertical shaft planet forced concrete mixer.

Traditional concrete mixer such as single horizontal axis forced mixer have very strong agitating function, but parts wear is fast, the maintenance cost height.The shaft level is installed, because the concrete slurry in stirring oozes, has the shaft end seal problem.Sealing device also need be changed, keep in repair after using certain hour reliably again, increases use cost.This machine manufacturing process complexity, the fault of meeting accident easily in the use, maintenance is also difficult.Energy consumption is higher, and mixing cycle is also longer.

The purpose of this utility model provides a kind of simple in structure, and is easy to manufacture, long service life, and the reliability height is safeguarded, and it is convenient to repair, and power consumption is little, productivity ratio height, concrete mixer with low cost.

The utility model comprises reducing gear, transmission mechanism, rabbling mechanism, tank body.Transmission mechanism has pivoting support 5 to be connected on the stirring supporting mass 2 on the tank body 14.The revolution revolving body 6 that is loaded on reducing gear power output shaft 4 is fixed on the bearing holder (housing, cover) 16 of pivoting support 5.There are several planet pinions 3 and the gear ring 17 of pivoting support (5) to mesh on the revolution revolving body 6.Be fixed with the mixing arm 11 of band blade 13 on the planet axis 7.Be fixed with scraper plate 12 on the revolution revolving body.Dump gate 15 is arranged at the bottom of garden cylindricality tank body 14.

Planet axis 7 of the present utility model can be equipped with axle sleeve 9.The

groove

23,18 of the phase profiling of the lower end of the two.The puddler 20 that cooperates with

groove

23,18 is loaded in the groove, and is connected with axle sleeve 9.There are pressing plate 19 and planet axis 7 to be connected.Puddler 20 two ends symmetries are fixed with installing plate 21, and mixing arm 11 is connected on the installing plate 21.

Two of can be its axle center and the power output shaft heart symmetry is installed on concentric line of planet axis 7 of the present utility model, perhaps for its axle center and the power output shaft heart equidistantly and to becoming three of hexagonal angle installation.Scraper plate 12 can be two, and symmetry is installed on the scraping rod 24 that is fixed on the revolution revolving body 6.

The gear ring 17 of pivoting support 5 of the present utility model can be the outer ring, and bearing holder (housing, cover) 16 is an inner ring.

The gear ring 17 of pivoting support 5 of the present utility model can be inner ring, and bearing holder (housing, cover) 16 is the outer ring.

The utility model stirring theory advanced person, existing tank body garden week stirring movement with the rabbling mechanism that subtracts mechanism's power output shaft rotation, have again with the mixing arm of planet axis rotation and the little garden Zhou Yundong of rotation of blade thereof, to stirring of material, fully, and the wearing and tearing of rabbling mechanism itself are little, and energy consumption is low, the productivity ratio height, long service life.

Power output shaft of the present utility model, the bearing of planet axis are stood high above the masses, and there is not the infiltration problem of material slurry in vertical installation, does not need shaft end seal, long service life, and the reliability height, maintenance cost is the end very.The flexible connection of planet axle sleeve of planet axis and band mixing arm had both strengthened the intensity of axle, was convenient to repair and replacement again.

The utility model is simple in structure, can use general purpose accessory cheap for manufacturing cost in a large number, can extensively replace existing single horizontal axis forced mixer.

Following is accompanying drawing of the present utility model:

Following is embodiment of the present utility model:

Planetary reduction gear 1 is fixed by bolts to and stirs on the supporting mass 2.Gear ring 17 is fixed by bolts on the stirring supporting mass 2 by installing ring 25 for the pivoting support 5 of outer ring.On the revolution revolving body 6 on three lines of centres symmetry be installed in two planet axis 7, jackshaft is felt at ease on the power output shaft 4 that is contained in decelerator 1.Planet pinion 3 meshes with the gear ring 17 of pivoting support, and there are bearing and bearing cap in its two ends.Planet axis 7 extensions are equipped with the axle sleeve 9 of band groove 22, and all there is the groove with half garden arch both lower ends.23，18。Puddler 20 passes slot welding and is connected on the axle sleeve 9.There is pressing plate 19 to be screwed on axle 7.The mixing arm 11 of band blade 13 is housed with bolt on the installing plate 21.Two puddlers are installed at an angle of 90.The scraping rod of installing at an angle of 90 with axial line 24 is arranged on the revolution revolving body 6.Scraper plate 12 is equipped with near the arm of tank body 14 in the scraping rod two ends.Tank base has Dump gate 15.

Revolution revolving body 6 also can be mutually hexagonal angle as shown in Figure 7 three planet axis 7 are installed.The puddler of stirring thereon and the installation site of mixing arm should guarantee can not run foul of each other in rotation.According to same principle planet axis 7 even can be more than three, this is suitable for for large-scale tank body.
