Abstract
The invention discloses a cycle structure of a straight barrel type concrete mixing transportation truck, comprising a straight barrel, stirring blades, a discharge pipe and a feeding back hole, wherein the straight barrel is in the shape of a cylinder and is vertically fixed on a motorcar chassis through a fixing rack; the stirring blades are provided with a rotating shaft, and are inserted into the straight barrel from the upper end of the straight barrel; the feeding back hole is positioned on the barrel wall of the upper part of the straight barrel and is slightly higher than the surface position of concrete in the barrel; and the discharge pipe is a hose and is positioned on the barrel wall of the side face of the bottom of the straight barrel, and a pipe mouth is inserted in the feeding back hole when no material is discharged. The invention has simple structure, pressure difference can be formed whether the stirring blades positively rotate or reversely rotate when in use, the concrete in the discharge pipe is pushed to upwards or downwards move so as to form cycle movement, the concrete in the discharge pipe and the concrete in the straight barrel are well mixed and are not condensed, and the invention is suitable for all of the straight barrel type concrete mixing transportation trucks.
Description
Technical field the present invention relates to a kind of loop structure, especially the loop structure of straight barrel type concrete mixing transportation truck.
Since the mid-90 20th century of background technology concrete mixing and transporting car, China's concrete mixer truck has obtained fast development, and the enforcement of the fast development of this and urban construction and bulk cement planning is completely inseparable.Its special mechanism mainly comprises power takeoff, mixing drum front and back support, reductor, hydraulic system, mixing drum, operating mechanism, purging system etc.Operation principle is, takes out by the power of power takeoff with automobile chassis, and drives the variable pump of hydraulic system, mechanical energy is converted into hydraulic pressure can passes to fixed displacement motor, and motor drives reductor again, drives agitating device by reductor, and concrete is stirred.Concrete mixer truck can adopt 2～5 bridge chassis, but 3 bridge chassis (6 * 4) wherein are the market main forces always, its power takeoff, fixed mount, reductor, hydraulic motor and hydraulic pump, ECU, even stirring vane etc. is the world of several import brands always, is difficult to so far change.Agitator tank and other parts are only " patent " of domestic enterprise.The expansion vehicle of concrete mixing and transporting car has concrete mixer truck, the concrete of preceding discharging to stir the concrete mixer truck of conveying semi-trailer, band concrete conveyer belt, mixer lorry of band concrete pump truck system or the like.No matter which kind of vehicle, the mixing drum of concrete mixing and transporting car all adopt the inclination form to be fixed on the automobile chassis.This structure need drive the mixing drum rotation, and consumes energy is more; The area that takies automobile chassis is bigger; Concrete mixing and transporting car scatters concrete from feed inlet and outlet easily when passing a bridge upward slope.
Submitted " straight barrel type concrete mixing transportation truck " patent simultaneously to the present invention, it is made up of straight bucket, fixed mount, agitation blades, transmission mechanism, actuating unit, charging aperture and discharge nozzle, wherein, straight bucket is cylindrical, and straight bucket is erect by fixed mount and is fixed on the automobile chassis; Discharge nozzle is a flexible pipe, is positioned at the bottom sides bucket wall of straight bucket, and the mouth of pipe is placed in the position that is higher than charging aperture during not discharging.Problem is: how the concrete that is arranged in discharge nozzle is fully mixed, noncondensing?
Summary of the invention purpose of the present invention is exactly the loop structure that a kind of straight barrel type concrete mixing transportation truck simple in structure will be provided, and makes that the concrete that is arranged in discharge nozzle is fully mixed, and is noncondensing.
In order to achieve the above object, the loop structure of straight barrel type concrete mixing transportation truck provided by the invention is made up of straight bucket, agitation blades, discharge nozzle, back material hole, and wherein, straight bucket is cylindrical, and straight bucket is erect by fixed mount and is fixed on the automobile chassis; Agitation blades has turning cylinder, and agitation blades is inserted straight bucket from the upper end of straight bucket; Back material hole is positioned at straight bucket top bucket wall, a little more than the surface location of bucket inner concrete; Discharge nozzle is a flexible pipe, is positioned at the bottom sides bucket wall of straight bucket, and the mouth of pipe inserts back material hole during not discharging.When the present invention used, no matter agitation blades was just changeed or reversed, and all can form pressure differential, and the concrete that promotes in the discharge nozzle moves up or down, formed shuttling movement, and the interior concrete of concrete and straight bucket in the discharge nozzle is fully mixed, and is noncondensing.
The loop structure of straight barrel type concrete mixing transportation truck provided by the invention has positive effect: forms by straight bucket, agitation blades, discharge nozzle, back material hole, and simple in structure; During use no matter agitation blades just change or reverse, all can form pressure differential, the concrete that promotes in the discharge nozzle moves up or down, form shuttling movement, concrete in the discharge nozzle is fully mixed with straight barrel of interior concrete, noncondensing, be applicable to all straight barrel type concrete mixing transportation trucks.
Description of drawings the present invention will be further described in conjunction with the accompanying drawings, please referring to accompanying drawing:
Accompanying drawing 1 expression schematic diagram of the present invention.
Structure shown in the accompanying drawing 1 comprises: charging aperture 1, back material hole 2, surface location 3, agitation blades 4, straight bucket 5, discharge nozzle 6, automobile chassis 7.
The loop structure of specific embodiment straight barrel type concrete mixing transportation truck provided by the invention is made up of straight bucket 5, agitation blades 4, discharge nozzle 6, back material hole 2, and wherein, straight bucket 5 is cylindrical, and straight bucket 5 is erect by fixed mount and is fixed on the automobile chassis 7; Agitation blades 4 has turning cylinder, and agitation blades 4 is inserted straight bucket 5 from the upper end of straight bucket 5; Back material hole 2 is positioned at straight bucket 5 top bucket walls, a little more than the surface location 3 of bucket inner concrete; Discharge nozzle 6 is a flexible pipe, is positioned at the bottom sides bucket wall of straight bucket 5, and the mouth of pipe inserts back material hole 2 during not discharging.When the present invention used, no matter agitation blades 4 was just being changeed or reversed, and all can form pressure differential, and the concrete that promote in the discharge nozzle 6 move up or down, formed shuttling movement, and concrete and the straight bucket 5 interior concrete in the discharge nozzle 6 are fully mixed, and is noncondensing.
Protection domain of the present invention relates to all changes form recited above.
