Truncated rectangular pyramids shape electrodynamic mechanical type feed appliance
Technical field
The present invention relates to construction implement technical field, be specially adapted to the truncated rectangular pyramids shape hopper that concrete-agitating controls in charging equipment automatically.
Background technology
In the automatic control charging equipment that current concrete mixing plant uses, truncated rectangular pyramids shape hopper has dress electromagnetic shaker and screw impeller two kinds, is all to make the medium sand in truncated rectangular pyramids shape hopper automatically drop to conveyer belt or fall in mixer, it is even that dress electromagnetic shaker and the truncated rectangular pyramids shape hopper of dress screw impeller are all applicable to sand grains, moisture content is below 8%, the good medium sand of mobility, and for the medium sand of moisture content more than 8%, or with the medium sand of broken little freezing caking, just be difficult to be suitable for, often cause medium sand blocking in truncated rectangular pyramids shape hopper, can not fall, and do not meet mixed concrete code requirement yet, the medium sand of broken little freezing caking easily causes the concrete of building to occur honeycomb, this is also one of quality accident reason causing casting concrete serious, when medium sand is poured into truncated rectangular pyramids shape hopper from top to bottom by loading machine, impulsive force is large, increase the bulk density of medium sand in truncated rectangular pyramids shape hopper, and the medium sand that humidity is larger, adhesion strength is also large, support force is larger, in addition under the shock effect of electromagnetic shaker, medium sand is assembled along truncated rectangular pyramids shape hopper slope wall four direction toward end opening, and distance between conveyer belt and truncated rectangular pyramids shape hopper end opening is little, medium sand is loaded when conveyer belt does not transmit, more closely knit, can not flow, the particularly more difficult downslide of medium sand at truncated rectangular pyramids shape hopper corner place, lose mobility, can not automatically fall, and in screw impeller promotion truncated rectangular pyramids shape hopper during medium sand, form lower empty upper paulin, medium sand can not be made automatically to fall, automatic charging equipment is lost and automatically controls batching and material loading function, also need workman to be dug out by medium sand with spade one spade spade, after unimpeded, then medium sand one spade one spade is loaded in truncated rectangular pyramids shape hopper, waste a large amount of time, artificial and mechanical expense like this, and delay again the construction period, often cause the quality accident of concrete works frostbite and increase engineering cost.
