Background technology
Concrete mixing and transporting car constitutes car load by subframe, tank body, drive system, stirring system, flushing system, input and output material system and automobile chassis.Wherein tank body is the main element of concrete mixing and transporting car, and tank body is mainly blade except that ladle bowl, and the blade continuous welding is on the helical of ladle bowl inside.
At present, the tank body helical of the concrete mixing and transporting car in the use and blade are mainly Archimedes spiral and uniform pitch helical.
Whether helical and the blade of weighing tank body be good and bad, mainly contains the following aspects:
1. the even matter degree that stirs of concrete.Be under the identical tank body volume, whether exist and stir inequality or segregation phenomenon occurs.
2. stir the discharge rate of tank body.Under the same volume, whether speed is fast in the tank body discharging.
3. adapt to the slump scope.Whether evenly discharging under the wide region slump.
At present, the tank body in the use can not satisfy above-mentioned three kinds of requirements simultaneously.
The utility model content:
Goal of the invention of the present utility model is to overcome the deficiency of background technology and the concrete mixing and transporting car tank body screw structure that a kind of discharge rate is fast, stir, adapt to the slump wide ranges is provided.
The utility model adopts following technical scheme:
A kind of concrete mixing and transporting car tank body screw structure, comprise tank body inner cone helical, the inner cone blade, save helical in the tank body, middle joint blade, bore helical behind the tank body, back awl blade, described tank body inner cone helical adopts variable element logatithmic spiral structure, and tank body inner cone helical reduces 5 ° from the big small end lead angle of holding, the joint helical adopts and decides parameter logatithmic spiral structure in the described tank body, and the awl helical adopts variable element logatithmic spiral structure behind the described tank body, and the awl helical reduces 8 ° from the big small end lead angle of holding behind the tank body; Describedly place the inner cone blade on the tank body inner cone helical to be straight thread spiral camber structure, the described joint blade that places tank body to save on the helical is straight thread spiral camber structure, and the described back awl blade of boring on the helical behind the tank body that places is non-straight thread spiral camber structure.
The utility model of employing technique scheme is compared with prior art afterwards bored blade and is non-straight thread spiral camber structure, has increased blade band material amount; The logatithmic spiral that is adopted improves and stirs even matter degree; Tank body inner cone helical from big hold the small end lead angle to reduce 5 ° and tank body after the awl helical reduce 8 ° of advantages that adapt to the slump wide regions from the big small end lead angle of holding.
As a kind of preferred version of the present utility model, described tank body inner cone helical reduces 5 ° of employing linear interpolation methods from the big small end lead angle of holding.
As a kind of preferred version of the present utility model, the awl helical reduces 8 ° of employing linear interpolation methods from the big small end lead angle of holding behind the described tank body.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with drawings and Examples in detail the utility model is described in detail:
A kind of concrete mixing and transporting car tank body screw structure is referring to accompanying drawing 1, among the figure: cone shell 1 before the tank body, joint housing 2 in the tank body, cone shell 3 behind the tank body, back awl blade 4, awl helical 5 behind the tank body, middle joint blade 6, joint helical 7 in the tank body, inner cone blade 8, tank body inner cone helical 9.
In the present embodiment, cone shell 1 interior tank body inner cone helical 9 adopts variable element logatithmic spiral structures before placing tank body, this logatithmic spiral structure has improved the stirring homogeneity, and tank body inner cone helical 9 reduces 5 ° from the big small end lead angle of holding, that is: tank body inner cone helical 9 saves housing 2 direction lead angle of cone shell 1 before tank body and reduces 5 ° from tank body, and reducing of lead angle is in order better to adapt to wide region slump concrete input and output material.
Place tank body joint helical 7 employings in the tank body joint housing 2 to decide parameter logatithmic spiral structure, this logatithmic spiral structure has improved the even matter degree of stirring; Place behind the tank body that awl helical 5 adopts variable element logatithmic spiral structures behind the tank body in the cone shell 3, this logatithmic spiral structure has improved and has stirred even matter degree, and awl helical 5 reduces 8 ° from the big small end lead angle of holding behind the tank body, promptly; Awl helical 5 save housing 2 direction lead angle of cone shell 3 behind tank body and reduces 8 ° behind the tank body from tank body, and reducing of lead angle is for better adaptation wide region slump concrete input and output material.
Place the inner cone blade 8 on the tank body inner cone helical 9 to be straight thread spiral camber structure, place the joint blade 6 on the tank body joint helical 7 to be straight thread spiral camber structure, place the back awl blade 4 of boring on the helical 3 behind the tank body to be non-straight thread spiral camber structure.Back awl blade 4 is the three-dimensional non-spiral shell of facing directly and carves curved surface, has increased the band material amount of blade.
Tank body inner cone helical 9 reduces 5 ° of employing linear interpolation methods from the big small end lead angle of holding.

Wherein the tank body helix calculates to bore and is:
Each symbol description is as follows:
α: half of circular cone drift angle
β: the helical angle of helix
ρ
0: it is long that circular cone pushes up round platform microcephaly's bus
ψ: space curve r and Z axle clamp angle
D: space curve length is the blade bus length
θ: parameter
The accounting equation of tank body helix on X-axis, Y-axis and Z-direction is respectively:
Utilize the logarithmic equation formula to utilize computer to carry out logarithmic equation and calculate, calculate spiral path, with calculating computer and launching helical blade.
