Abstract
The utility model provides a material discharging elbow device of a concrete sprayer, and belongs to the technical field of material discharging devices for manufacturing mixture. The material discharging elbow device comprises an elbow spirally connected to the lower surface of a lower seat body of the sprayer, wherein a material discharging end of the elbow is connected with a material discharging cylinder; an inner cavity of the material discharging cylinder is in the shape of a cone of which the area of an inlet is larger than the area of an outlet; and an air inlet joint connected with an air inlet device is vertically or obliquely arranged on the material discharging cylinder and led into the inner cavity of the elbow. Through shortening the length of the existing elbow, connecting the material discharging cylinder to the lower end of the elbow and well connecting the air inlet joint on the material discharging cylinder with the air inlet device, when the material discharging elbow device of the concrete sprayer is used, the concrete mixture is easy to be blown out without influencing normal use of the sprayer under the action of air pressure of an air inlet device at a rotor block part of the sprayer and the action of air pressure of the air inlet device at the material discharging cylinder.
Description
Technical field
The utility model relates to the drawing mechanism technical field of making compound, refers to a kind of concrete sprayer discharging head bending device especially.
Background technology
Concrete sprayer is to utilize compressed air that concrete is carried along pipeline continuously, and is ejected into the machinery that working face gets on.During its work,, drive reductor work through electric motor starting; Rotor block and agitator that speed reducer output shaft drives on it rotate simultaneously, and concrete mix is stirred through the agitator that is positioned at the hopper inner chamber after getting into feed hopper; Respectively expecting in the chamber of entering rotor block; And through locating injecting compressed air at this, center line blows concrete mix to following discharging elbow by rotor block along the material chamber to make compressed air, and ejects from the discharging elbow.
But existing discharging elbow is the whole bend pipe of being cast by metal material, and its upper end is welded in spraying machine lower base soffit; During use; Because existing spraying machine only is provided for blowing the inlet duct of material in the position, material chamber of rotor block, compressed air active force when having arrived the elbow crooked position that inlet duct is blown into obviously reduces, and makes concrete mix be not easy to eject from elbow; And be bonded in discharging elbow internal chamber wall easily, influence the normal use of spraying machine.
The utility model content
The purpose of the utility model is to provide a kind of concrete sprayer discharging head bending device, and it in use easily with the concrete mix ejection, does not influence the normal use of spraying machine.
To achieve these goals; The technical solution of the utility model is: a kind of concrete sprayer discharging head bending device; Comprise the elbow that is bolted in below the spraying machine lower base, the discharge end of wherein said elbow is connected with discharge barrel, and what the cavity shape of said discharge barrel was an inlet-duct area greater than discharge area is coniform; Vertical or tilt to be provided with the inlet suction port that is connected with inlet duct, the inner chamber of said inlet suction port feeding elbow on the said discharge barrel.
The utility model concrete sprayer discharging head bending device, the inner chamber of wherein said elbow and discharge barrel is respectively equipped with elbow lining and discharge barrel lining, and said elbow lining and discharge barrel lining are processed by elastomeric material.
The utility model concrete sprayer discharging head bending device; The external surface bottom of wherein said elbow is provided with flange; The external surface top of said discharge barrel is provided with the uncovered tubbiness link in upper end; Said flange is connected through bolt with the upper end of link to be fixed, and is provided with rubber gasket between said flange and the link.
After adopting such scheme; The utility model concrete sprayer discharging head bending device connects a discharge barrel through with existing elbow contraction in length in its lower end, and an inlet suction port on the discharge barrel and an inlet duct are connected; During use; Concrete mix blows out concrete mix under the gas pressure of the inlet duct at the gas pressure of the inlet duct at spraying machine rotor block position and discharge barrel place easily, does not influence the normal use of spraying machine.

Below in conjunction with accompanying drawing, the utility model is done further explanation through embodiment;
The specific embodiment
As depicted in figs. 1 and 2; The utility model concrete sprayer discharging head bending device; It comprises through bolt and is bolted in the metal material elbow 1 below the spraying machine lower base; The inner chamber of elbow 1 is equipped with the elbow lining 4 that the elastomeric material of high abrasion is processed, and the external surface bottom of elbow 1 is processed with flange 7.The lower end of elbow 1 is connected with discharge barrel 2, and what the cavity shape of discharge barrel 2 was an inlet-duct area greater than discharge area is coniform, and the inner chamber of discharge barrel 2 is equipped with the discharge barrel lining 5 that the elastomeric material of high abrasion is processed.The external surface top of discharge barrel 2 is processed with the uncovered tubbiness link 8 in upper end, and flange 7 is connected through bolt with the upper end of link 8 to be fixed, and is provided with rubber gasket 6 between flange 7 and the link 8.Design can guarantee the sealing between elbow 1 and the discharge barrel 2 like this.In conjunction with Fig. 3 and shown in Figure 4, vertical or tilt to be processed with the inlet suction port 3 that is connected with inlet duct, the inner chamber of inlet suction port 3 feeding elbows 1 on the discharge barrel 2.
The utility model concrete sprayer discharging head bending device picks out barrel 2 through with existing elbow 1 contraction in length at its lower end snail, through inlet suction port 3 is set on discharge barrel 2, an inlet suction port 3 and an inlet duct is connected.During use, concrete mix is at the inlet duct gas pressure at spraying machine rotor block position, and this air pressure is along the centerline direction effect of elbow 1 and discharge barrel 2; And under the gas pressure of the inlet duct at discharge barrel 2 places, this air pressure forms bumpy flow along discharge barrel 2 inner chambers, easily concrete mix is blown out this head bending device, does not influence the normal use of spraying machine; Inner chamber at elbow 1 and discharge barrel 2 is nested with the elbow lining 4 and discharge barrel lining 5 that high wear-resistant rubber is processed respectively simultaneously; Because rubber has non-caked concrete characteristics; Guarantee that concrete mix sprays head bending device smoothly; The ability of this apparatus processes wet feed is greatly enhanced, and has significantly reduced cleaning and maintenance load.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that the common engineers and technicians in this area make the technical scheme of the utility model all should fall in the protection domain that claims of the utility model confirm.
