Disclosure of Invention
In order to solve the problems, the invention provides a building material processing device which solves the problems that the concrete mixing efficiency is low and the concrete cannot be quickly discharged out of a mixing drum.
In order to achieve the purpose, the invention adopts the technical scheme that: a building material processing device comprises a support frame, wherein a mixing drum is fixedly connected to the support frame, a discharge port is formed in the bottom of the mixing drum, a rotating shaft is coaxially arranged in the mixing drum, a driving unit for driving the rotating shaft to rotate is arranged on the mixing drum, and the rotating shaft comprises an upper rotating shaft and a lower rotating shaft which are mutually linked; the upper rotating shaft is fixedly connected with an upper spiral sheet, the lower rotating shaft is fixedly connected with a lower spiral sheet, a reversing mechanism used for changing the relative rotating direction of the upper rotating shaft and the lower rotating shaft is arranged between the upper rotating shaft and the lower rotating shaft, and the lower rotating shaft is close to the discharge hole.
The principle of the invention is as follows: the concrete is stirred in the stirring cylinder, and the stirred concrete is discharged from the discharge port; because the pivot includes the last pivot of mutual linkage and pivot down, when consequently drive unit drive pivot was rotatory, go up the pivot and rotate under drive unit drive power effect with the lower pivot homoenergetic to the flight rotates with lower flight in the drive, realizes the stirring to concrete in the churn. A reversing mechanism is arranged between the upper rotating shaft and the lower rotating shaft, so that the relative rotating directions of the upper rotating shaft and the lower rotating shaft can be changed, under the action of the reversing mechanism, if the rotating directions of the upper rotating shaft and the lower rotating shaft are opposite, the stirring and pushing directions of the upper spiral sheet and the lower spiral sheet on concrete are opposite, and in order to facilitate the rapid mixing of the concrete in the mixing drum, the spiral directions of the upper spiral sheet and the lower spiral sheet can be set, so that when the upper spiral sheet and the lower spiral sheet stir and push the concrete, the upper spiral sheet and the lower spiral sheet push the concrete to the middle part of the mixing drum, and the concrete is continuously fused and rapidly mixed uniformly; when last flight and lower flight are in the syntropy and rotate under reversing mechanism's switching-over effect, go up the flight and form the helical blade of a folk prescription stirring and promotion concrete with the combination of lower flight for the concrete can be pushed to the one end of churn fast, like in this application, can push away the concrete to bin outlet one end, thereby make the good concrete of stirring arrange away fast, reduce row material time, make whole stirring cycle time shorten, promote the stirring efficiency of concrete.
The scheme has the advantages that:
1. can arrange material fast: compare in prior art after the concrete accomplishes the stirring, the concrete relies on self gravity to be discharged from the bin outlet, and the stirring arm hardly has too big influence to the row of concrete, therefore the inefficiency of concrete discharge churn influences the whole cycle of concrete mixing. In this application, utilize the flight and the cooperation of flight down, not only can realize quick, the high-efficient mixture of concrete, simultaneously, through the switching function of switching mechanism, make the concrete after the stirring can be promoted discharge opening department fast to make the concrete can be arranged away fast, promote the stirring efficiency of concrete.

High-speed stirring: compare in prior art concrete and be the circulation flow stirring, in this application in the stirring stage, go up the flight and when the flight stirred concrete, promoted with lower flight, the concrete is flowed to the middle part by the churn both sides, and the concrete relative motion that the concrete that goes up the flight and promote with lower flight to make the concrete flash mixed, make the stirring mixing speed of concrete faster.
3. Is beneficial to reducing the cost: because concrete weight is heavier in the churn, and the concrete just can be discharged after accomplishing intensive mixing even, and among the prior art, when the row material after the concrete is accomplished the stirring, the rabbling arm also need constantly stir, make the concrete by the discharge churn, in this application, utilize the impetus of last flight and lower flight, make the concrete discharge you it fast, the invalid churning time of rabbling arm when reducing the row material, effective energy saving and reduction stirring cost.
Further, the vertical setting of churn, drive unit include fixed connection at the first motor at churn top, go up pivot and first motor fixed connection, the lower pivot is close to the bin outlet.
The vertical setting of churn and down the pivot is close to the bin outlet, and the churn upside is equipped with the feed inlet, and consequently the concrete removes from top to bottom in the churn, can effectively utilize concrete self action of gravity to assist the stirring, makes the stirring go on fast, and the stirring is accomplished the back, can make the concrete discharge fast.
