Description

The concrete mixing and transporting car tank body

Technical field

The utility model relates to building engineering equipment, is specially a kind of concrete mixing and transporting car tank body.

Background technology

Concrete mixing and transporting car is to be engaged in the special-purpose vehicle that commerical ready-mixed concrete stirs transportation; It is the modernized special-purpose vehicle that is transported to commerical ready-mixed concrete from special mixing plant the construction site; It is to be assembled as main workpiece by truck chassis, last dress stirring tank body and Hydraulic Power Transmission System; Tinning body is the concrete carrying container on it, in establish the tank body helical mixing blade, helical mixing blade is except that keeping a jar inner concrete do not emanate; Also can operate, to realize concrete is transported to the task of job site through the auxiliary input and output material of accomplishing of transmission system.

In general, the concrete mixing and transporting car whipping performance is in stirring tank body, to realize through rotatablely moving of blade that blade and material (stone, sand, cement mortar) continuously collide to accomplish; Input and output material then falls to realizing through blade pitch movements and material certainly.And the blade that adopts in now general concrete mixing and transporting car tank body design; On inner cone, middle tube and back awl; Each size and helical angle, lead angle does not have evident difference, ignored each section of mixing drum make when installing with horizontal angle to the helical mixing blade of the influence of motion generation and each section the function difference that should have; Thereby energy consumption is big the time, and mixing effect is but desirable not to the utmost.

The utility model content

The technical problem that the utility model solved is to provide a kind of concrete mixing and transporting car tank body, to solve the shortcoming in the above-mentioned background technology.

The technical problem that the utility model solved adopts following technical scheme to realize:

The concrete mixing and transporting car tank body comprises tank body and jar inside spin stirring vane, wherein; Jar inside spin stirring vane comprises two groups; Be fitted on the inner tank wall, tank body part then comprises inner cone section, middle tube section, back awl section, thereby the helical mixing blade of fitting in it is also different.

Said inner cone section adopts and does not wait lift angle oblique cone logarithm helical mixing blade; Gradually wide type straight grained helical is adopted in the stirring vane cross section; Its helicoid width (blade height) is 260mm-320mm, and helical angle is that 71 °, lead angle are 19 °, to satisfy its agitating function and feeding function fully.

The tube section spiral line adopts spiral of Archimedes in the said helical mixing blade; Simultaneously; Gradually wide type straight grained helical is adopted in the stirring vane cross section; Helicoid width (blade height) 320mm-410mm, helical angle is that 70 °, lead angle are 20 °, to strengthen and to satisfy it and stir and the input and output material function.

The awl section has adopted the lift angle oblique cone logarithm spiral blade of inequality behind the said helical mixing blade; The non-straight grained helical of gradually wide type is adopted in the cross section; Helicoid width (blade height) is 410mm; Helical angle is that 75 °, lead angle are 15 °, improves the wearing and tearing that the discharging performance reduces blade in order to satisfy.

In the utility model, the awl section extends to guide tube and discharging opening place to the helical mixing blade front end in the said tank body in the back.

Beneficial effect: the utility model utilizes the computer simulation technology; Set up desirable input and output material motion model; It is theoretical to introduce desirable calculating awl; Set up the numeral expression of the helical curve motion of helical mixing blade inner cone section, middle tube section and awl section cylindrical shell actual installation position, back, required parameter designing when realizing the stirring vane screw draws two-fluid model and agitated medium in the concrete mixing and transporting car mixing drum is entered simplifies simulation numerical value.Simultaneously, through practice examining, solved concrete mixing and transporting car tank body helical mixing blade and satisfied under its working condition requirement prerequisite, it is about 6% that car load helical mixing blade manufacturing cost is reduced, and it is about 3.5% that average energy consumption reduces, and is suitable for car load and produces in batches and use.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.

Embodiment referring to the concrete mixing and transporting car tank body of Fig. 1; In the present embodiment; Tank body is divided into 4 three sections of inner cone sections 1, middle tube section 2, back awl section, and the helix 3 among the figure be the running orbit line of its internal helicoid stirring vane, and back awl section 4 is terminal through guide cylinders 6 connection feeding cylinders 5; Simultaneously, below feeding cylinder 5, also have a discharging opening 7.

Referring to the A-A cross section of Fig. 2, this cross section is inner cone section 1 Along ent blade and preceding conic tube bus 8 actual installation operating positions.Dash area is the cross section of concrete materials actual motion, and its volume is the geometric volume of this place's helicla flute and blade height 260mm, and its fundamental section is a rectangle.Helical blade always moves forward and backward the material of this geometric volume owing to the rotation of cylindrical shell.
