Abstract
The utility model discloses a spiral blade assembly of a concrete mixing tank. Each pair of spiral blades are in variable-angle logarithmic spiral design, vertical cylindrical walls of the blades are fixedly arranged by means of welding, a tank body is divided into a front cone, a middle barrel and a rear cone, an opening of the tank body is arranged on the rear cone, the pitch of the blades of each of the middle barrel and the rear cone is larger than that of the blades of the front cone, two short-lead spiral blades extending to the opening are further arranged on the cylindrical wall of the rear cone, and the short-lead spiral blades and two integral spiral blades are arranged at intervals. The concrete mixing tank with the blade assembly with the structure has the advantages that after a rated quantity of concrete is loaded, the materials cannot spill or leak when an integral vehicle descends a slope with the inclination ranges from 7 degrees to 10 degrees, and the unloading speed is obviously increased.
Description
Technical field
The utility model belongs to the agitator tank of concrete mixer truck, is specifically related to the helix blade of a sharp concrete drums.
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 available coagulation soil agitator truck tank body blade; 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.
The utility model content
In order to overcome the problems referred to above that the prior art field exists; The purpose of the utility model is; 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.
The concrete drums helix blade that the utility model provides; 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.
The concrete drums helix blade that the utility model provides; 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 utility model embodiment.
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, the concrete drums helix blade to the utility model provides carries out detailed explanation.
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, and tank body is divided into inner cone part, middle tube, back taper portion; 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.
3. concrete drums helix blade according to claim 1 is characterized in that: the helical pitch of said short lead helix blade is 0.5 circle.
4. according to claim 1 or 3 described concrete drums helix blades, it is characterized in that: 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.
5. concrete drums helix blade according to claim 4 is characterized in that: 4 helix blades of back taper portion, the spacing on barrel equates.
