Abstract
The utility model discloses a feed back system, including feeding mechanism, feeding mechanism is including the flat belt and oblique belt of cooperation pay -off, the flat belt is disposed under the aggregate storehouse, the one end of belt extends to stirring station main building to one side, still includes feed back mechanism, feed back mechanism includes feed back fill and feed screw, the opening setting that the feed back was fought is in the linking department below of oblique belt and flat belt, feed screw one end communicates with the lower part that the feed back was fought, and its other end extends to stirring station main building. The phenomenon that can not appear in the time of can guaranteeing the feed back losing, and the feed screw is unsuitable, and to transport the material great, thus unsuitablely directly carry the aggregate through the feed screw, but it is less to lose the general particle diameter of aggregate that falls, so relatively suitable pay -off.
Description
Technical field
The utility model relates to a kind of transportation system, is used for the conveying of aggregate, and more particularly, it relates to a kind of material return system.
Background technology
Concrete mixing plant is used to the concrete combined unit of concentrated compactness, also known as concrete prefabricated field.Because its mechanization, automaticity are higher, so productivity ratio is also very high, and concrete quality can be ensured and save cement, being usually used in the engineering such as large and medium-sized water conservancy, electric power, bridge that concrete works amount is large, long in time limit, building site is concentrated.Along with the development of urban construction, adopt concentrated compactness, provide the concrete mixing plant tool of commodity to have an enormous advantage, thus developed rapidly, and be popularization Concrete Pumping Construction, realization is stirred, carry, build mechanical integration of operation creates conditions.
But in the delivery system of aggregate, its principle be first by opening on ground and the aggregate bin being embedded in underground carries out pan feeding, then feeding is carried out by connecting gear, connecting gear is preset in basement, connecting gear comprises at least one flat belt and an oblique belt carries out conveying aggregate, accesses flat belt by aggregate bin, and under the drive of flat belt, carry out one end that oblique belt is sent in splicing simultaneously, then deliver to mixing plant main building by oblique belt and stir.
There is some problems in actual use in this feeding structure, due to being driven by motor of oblique belt, and aggregate is uneven, so during feeding, the aggregate easily appearing at oblique Belt Conveying easily naturally drops or is shaken off, and lose loose so have more material in the gap of the joining place of flat belt and oblique belt, one carrys out cost of idleness, two because this organization establishes is in underground, so clean also very inconvenient.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is that providing a kind of can not cause a kind of material return system of phenomenon of being scattered by feed back in time when leaking material.
For achieving the above object, the utility model provides following technical scheme: a kind of material return system, comprise feed mechanism, described feed mechanism comprises the flat belt and oblique belt that coordinate feeding, described flat belt is arranged on the below of aggregate bin, one end of described oblique belt extends to mixing plant main building, also comprise material return mechanism, described material return mechanism comprises back hopper and feed screw, the opening of described back hopper is arranged on below the joining place of described oblique belt and flat belt, described feed screw one end is communicated with the bottom of back hopper, its other end extends to mixing plant main building.
Screw(-type) feeder carries out sense weight the material of process by crane span structure of weighing, to determine the weight of material on adhesive tape, rear-mounted Digital Speed Testing sensor, the speed of service of continuous measurement batcher, the pulse of this velocity sensor exports the speed being proportional to batcher, rate signal sends into feeder controller together with weight signal, and the microprocessor in controller processes, and produces and shows cumulative amount/instantaneous delivery.This flow compares with setting flow, is outputed signal and controls frequency converter and change the actuating speed of batcher, the mass flow on batcher is changed by control instrument, close to and remain on set feed flow, thus realize the requirement of dosing.And feed screw is applied in herein, there will not be something lost to fall phenomenon when can ensure feed back, and feed screw to be not suitable for transporting material larger, so be not suitable for directly carrying aggregate by feed screw, but it is less to lose the general particle diameter of aggregate fallen, so be relatively applicable to feeding.
Further: described flat belt and oblique belt exist intersection in the projection perpendicular to ground.Namely a part for flat belt is arranged on directly over oblique belt, so arrange like this, when feeding, under flat belt normal operating conditions, material can be delivered to directly over oblique belt, and the aggregate that just directly can not there is particle diameter large when being connected like this drops.
Further: the length range of described intersection is 2-20 decimetre.By arranging the length of intersection, the effect that aggregate transports can be ensured further.
Further: the angle of inclination of described oblique belt is less than 60 degree.The angle of inclination of described oblique belt can ensure be less than 60 degree, can ensure to there will not be the situation of leaking material.
Further: described oblique belt is provided with some baffle plates.
By arranging baffle plate, when there is vibration, there is aggregate can be blocked by baffle plate, can not there is the situation occurring too much leaking material because of aggregate transition.
Further: described feed screw is controlled by control button work, described control button is configured in mixing plant main building.By the setting of control button, hopper can being worked as when collecting certain leakage material, can rewinding be concentrated by control button.
By adopting technique scheme, there will not be something lost to fall phenomenon when can ensure feed back, and feed screw to be not suitable for transporting material larger, so be not suitable for directly carrying aggregate by feed screw, but it is less to lose the general particle diameter of aggregate fallen, so be relatively applicable to feeding.
