Description

A kind of middle-size and small-size concrete suitable for villages and small towns stirs transportation integration belt feeder

Technical field

The utility model is related to mechanical equipment for building more particularly to a kind of middle-size and small-size concrete stirrings suitable for villages and small towns Transportation integration belt feeder.

Background technology

Arm support pump truck has the function of integrating pumping and cloth, and with the propulsion of Urbanization Construction, building houses of countryside is big Amount uses arm support pump truck, but because of the not yet universal reason of rural area Concrete Mixing Station, rural area mostly uses greatly Site Mode ready-mixed concrete, stirring and pumping cloth work are completed by different machinery, and different machineries need specification to match, and take up an area Area is big, and installation and debugging are time-consuming, leads to low production efficiency, rural area mixing plant speed is excessively slow, far behind the arm support The rate of pumping of pump, causes equipment to waste；In addition road is narrow, some equipment are hard to reach last construction site, with That rural laborer is rare year by year and the rising year by year of artificial commission；Furthermore arm support pump truck is in the ground of rustic home construction It is more demanding to the granular size of concrete in concreting process, but the often required coagulation of rustic home construction The granular size of soil can not meet the requirement of arm support pump truck, and then, someone expects that carrying out rustic home using belt feeder builds institute The concrete needed is conveyed, and still, is used for the belt feeder of concrete conveyance currently on the market, does not have concrete raw material certainly Dynamic charging and concrete conveyance function, it is therefore, now defeated there is an urgent need for designing a kind of middle-size and small-size concrete stirring suitable for villages and small towns Send integrated belt feeder.

To solve the above-mentioned problems, other people utility models a kind of " a kind of arm support pump truck with forced stirrer " (application Number CN201621119292.1), increase a forced stirrer at car body rear portion and using a kind of folding Feeding device can solve stirring and the defect of conveying non-integral and compare traditional arm support pump truck volume bigger than normal, inconvenient in agriculture The defect of village's sections of road.But arm support pump truck is more demanding to the granular size of concrete, and particle cannot be too big, but often agriculture The granular size of the required concrete of village's building construction can not meet the requirement of arm support pump truck, be easy to happen concrete pumping pipe The phenomenon that road blocks.On this basis, other people utility model " a kind of mobile skins for pouring torsion-bending ratio concrete again Band the machine " (patent No.：CN201620320714.5), by belt feeder delivering concrete, the requirement to concrete particle size is not Height, but it does not have the function that automatic charging and stirring are carried out to the raw material of concrete, it is therefore desirable to it is divided into several equipment and matches Conjunction could realize that entire concrete stirring pours operation, not as good as existing mature Trinity arm-pump.

Therefore, it designs a while there is concrete stirring and conveying function, it is not high to concrete particle size requirements, again Whole equipment volume can be reduced, while labor intensity can be reduced again, by faster, it is more preferable, more environmentally friendly in a manner of Serving for Rural market Concrete stir transportation integration belt feeder, just seem very necessary.
