Background technique
In concrete mixing plant, needs for a certain proportion of powder, sand material and additive to be stirred, ultimately form not
The concrete of same specification.For example, cement material is to complete mixing after being weighed by cement weigher again.Cement enters cement weigher
Transport is completed by screw conveyor.However, under certain transfer efficiency, being difficult to protect since cement weigher capacity is very big
The accuracy for demonstrate,proving cement weigher metering, to influence the quality and qualification rate of concrete.
Summary of the invention
Technical problem to be solved by the utility model is: in order to improve the measuring accuracy of concrete mixing plant powder and conveying
Efficiency, the utility model provide a kind of mixing plant material measuring device.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of mixing plant material measuring device, packet
Include screw conveyor, packing element, weighing hopper, discharging butterfly valve, control unit, bracket, material balance, wherein the outlet of screw conveyor with
Weighing hopper wide at the top and narrow at the bottom is arranged in packing element connection, packing element lower section, and weighing hopper is fixed on bracket, is arranged at weighing hopper bottom end outlet
Discharging butterfly valve, discharging butterfly valve are connect with control unit, and control unit is also connected with the sensor being arranged on material balance simultaneously, metering
Material balance is arranged in bucket lower section.
Further, described control unit is pneumatic control unit.
Further, the pneumatic control unit is double stroke cylinder, and control discharging butterfly valve is half-open, standard-sized sheet, fully closed three
A state.
Further, pneumatic arch breaking device is set on the weigher.
Further, the material balance is cement weigher.
Using mixing plant material measuring device described in the utility model, when such as carrying out ingredient to cement, the incipient stage, metering
The discharging butterfly valve of bucket lower section is controlled as full-gear, realizes thick metering；When metering reaches setting value, discharging butterfly valve is switched
At half-open position, essence metering is realized, guarantee that cement-weighting precision, whole process are recycled according to ingredient discharge process and executed.In addition,
Conveying needs certain time when starting starting due to screw conveyor, the material that kept in weighing hopper first can be put into material at this time
Scale, to improve the efficiency of material conveying.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of mixing plant material measuring device described in the utility model；
In the figure, it is marked as
1- screw conveyor；2- packing element；The coarse-fine weighing hopper of 3-；4- pneumatic arch breaking device；5- discharging butterfly valve；6- two-pass gas
Cylinder；7- bracket；8- cement weigher.
Specific embodiment
With reference to the accompanying drawing 1, mixing plant material measuring device described in the utility model is described further.
As shown in Figure 1, mixing plant material measuring device described in the utility model, comprising: screw conveyor 1, packing element 2, thick
Smart weighing hopper 3, pneumatic arch breaking device 4, discharging butterfly valve 5, double stroke cylinder 6, bracket 7, cement weigher 8.
Wherein the outlet of screw conveyor 1 is connect with packing element 2, and up big and down small coarse-fine weighing hopper 3 is arranged below packing element 2,
The big mouth on coarse-fine 3 top of weighing hopper is input port, and the osculum of lower part is discharge port.
Coarse-fine weighing hopper 3 is fixed on bracket 7.
Pneumatic arch breaking device 4 is fixed on the outer wall of coarse-fine weighing hopper 3.
The discharge outlet of coarse-fine 3 bottom end of weighing hopper is arranged in discharging butterfly valve 5, and discharging butterfly valve 5 is connect with double stroke cylinder 6,
It can control discharging butterfly valve 5 in half-open and two state switchings of standard-sized sheet by double stroke cylinder 6.
Cement weigher 8 is set below coarse-fine weighing hopper 3.
Sensor is installed, double stroke cylinder 6 is connect with the sensor on PLC and cement weigher 8 on cement weigher 8.In cement weigher
Work original state, and PLC control double stroke cylinder is opened for full-gear；When cement value in cement weigher 8 reaches preset value, pass
Sensor is transmitted to PLC, and control double stroke cylinder 6 switches to 5 half-open position of discharging butterfly valve after PLC receives signal；The speed of material conveying
Slow down；When cement value reaches end value in cement weigher 8, sensor is transmitted to PLC, and PLC controls double stroke cylinder 6 after receiving signal
5 full-shut position of discharging butterfly valve is switched to, material conveying terminates.
When cement ingredient, cement is transported in coarse-fine weighing hopper 2 by packing element 2 by screw conveyor 1, passes through two-way row
Stroke cylinder 6 controls the formation of discharging butterfly valve 5 and is all turned on state, and cement is put into cement weigher 8, and when reaching, cement weigher 8 is preset
When cement value, two-way travel cylinder 6 controls discharging butterfly valve 5 and forms semi-open state, essence metering is realized, until reaching cement weigher 8
Variable when close, whole process according to ingredient discharge process recycle execute.
The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
