Abstract
The invention discloses a spiral blade for a concrete stirring tank. A pair of spiral blades adopts the changeable angle logarithmic spiral design; the blades are welded and fixed vertically to the barrel wall; a tank body is divided into a front cone part, a middle barrel and a rear cone part; the mouth of the tank body is formed at the rear cone part; the blade pitches of the middle barrel and the rear cone part are greater than the blade pitch of the front cone part; two short-lead spiral blades extending to the tank mouth are arranged on the barrel wall of the rear cone part; and the two short-lead spiral blades are alternately arranged with two integral spiral blades respectively. After a concrete mixing and transporting vehicle adopting the blades is loaded with a rated volume of concrete, not only can materials of the whole vehicle be not leaked or splashed on a slope with an angle of 7 to 10 degrees, but also the unloading speed is obviously accelerated.
Description
Technical field
The invention belongs to the agitator tank of concrete mixer truck, be specifically related to the helix blade of agitator tank on a kind of coagulation.
Background technology
Estimating two good and bad important indicators of concrete mixing and transporting car is: satisfying under the prerequisite of useful load, one will stir, and two want discharge rate fast.Engine idling condition can satisfy the requirement of pump truck to discharge rate down.The agitator tank blade adopts the design of helix blade, can satisfy the requirement of trucd mixer to discharge rate.The helix of agitator truck tank body blade on the available coagulation; No matter adopt archimedes curve, still be the angle log spiral; In order to satisfy indexs such as useful load, mixing uniformity, all more than 3 circles, long helical pitch causes the inhibition to discharge rate to the helical pitch of one-piece auger line blade; If but helical pitch then can cause material to spill seriously less than 3 circles.
Summary of the invention
In order to overcome the problems referred to above that the prior art field exists; The objective of the invention is to; A kind of concrete drums helix blade is provided, solves the long helical pitch of existing tank body helix blade and cause the inhibition to discharge rate, the little meeting of helical pitch causes material to spill serious problem.
Concrete drums helix blade provided by the invention; A pair of helix blade adopts the design of angle log spiral, and the vertical barrel welding of blade fixedly installs, and tank body is divided into inner cone part, middle tube, back taper portion; Tank body is opened on back taper portion; In the blade pitch of tube, back taper portion greater than the blade pitch of inner cone part, also be provided with two short lead helix blades that extend to jar mouthful on the barrel of back taper portion, they respectively with the alternate setting of two one-piece auger line blades; The helical pitch of said one-piece auger line blade is 2.5 circles; The helical pitch of said short lead helix blade is 0.5 circle; The helix function drive form of said short lead helix blade is identical with the helix function drive form of one-piece auger line blade back taper portion; 4 helix blades of back taper portion, the spacing on barrel equates.
Concrete drums helix blade provided by the invention; Its beneficial effect is, adopts the concrete mixing and transporting car of this kind structure blade, load the concrete of specified side amount after; Car load not only can not spill at last 7-10 ° of material when sloping, and speed is obviously accelerated when discharging.
Description of drawings
Fig. 1 is the overall structure sketch map of the embodiment of the invention.
Mark among the figure:
1. inner cone part; 2. middle tube; 3. back taper portion; 4. short lead helix blade; 5. charging is little; 6. one-piece auger line blade.
The specific embodiment
With reference to the accompanying drawings, in conjunction with embodiment,, carry out detailed explanation to concrete drums helix blade provided by the invention.
Embodiment
With reference to Fig. 1; The concrete drums helix blade of present embodiment; A pair of helix blade adopts the design of angle log spiral, and the vertical barrel welding of blade fixedly installs, and tank body is divided into inner cone part 1, middle tube 2, back taper portion 3; Tank body is opened on back taper portion 3; In tube 2, the blade pitch of back taper portion 3 greater than the blade pitch of inner cone part 1, also be provided with two short lead helix blades 4 that extend to jar mouthful on the barrel of back taper portion 3, they respectively with two one-piece auger line blade 6 alternate settings; The helical pitch of said one-piece auger line blade 6 is 2.5 circles; The helical pitch of said short lead helix blade 4 is 0.5 circle; The helix function drive form of said short lead helix blade 4 is identical with the helix function drive form of the back taper portion of one-piece auger line blade 6; 4 helix blades of back taper portion 3, the spacing on barrel equates.
Because pitch strengthens the material problem of bringing of spilling, a jar notch portion has adopted 4 helix blades in order to prevent the tank body back taper portion, the structure of 4 blades, and an awl jar mouthful place is provided with the little tube 5 of charging in the back, and material gets in the tank body through the little tube 5 of charging.Inner cone part 1, middle tube 2 blades adopt interactive surface fitting to form, and back awl blade all adopts the three-dimensional hybrid method for scanning to design, and makes the transition of each several part vane curvature smooth.After loading specified side amount concrete, car load not only can not spill at last 7-10 ° of material when sloping, and speed is obviously accelerated when discharging.
Claims (5)
1. concrete drums helix blade; A pair of helix blade adopts the design of angle log spiral, and the vertical barrel welding of blade fixedly installs, vertebra part, middle tube, back taper portion before tank body is divided into; Tank body is opened on back taper portion; It is characterized in that: the blade pitch of middle tube, back taper portion is greater than the blade pitch of inner cone part, also is provided with two short lead helix blades that extend to jar mouthful on the barrel of back taper portion, they respectively with the alternate setting of two one-piece auger line blades.
2. concrete drums helix blade according to claim 1 is characterized in that: the helical pitch of said one-piece auger line blade is 2.5 circles.
