Abstract

A concrete spreader comprises a bracket (1) and a hopper (2), wherein the hopper (2) is connected with the bracket (1); a discharge port (4) is arranged at the lower end of the hopper (2); and a discharge acceleration device (3) is arranged in the position of the discharge port (4). Compared with the prior art, under the action of the discharge acceleration device arranged in the position of the discharge port, concrete discharged through the discharge port has a certain initial speed, the speed is accelerated during the discharging process, and the concrete is relatively dense after falling into a steel tubular pile mould; through the adoption of the discharge acceleration device, the volume of concrete passing through the discharge port in a time unit is larger than the volume of the concrete passing through the discharge port in the unit time during natural dropping, so that the discharging quantity is enlarged without widening the opening degree of the discharge port; moreover, as the discharge acceleration device is not in complete contact with concrete, the viscous effect of the concrete on the discharge acceleration device is smaller, which ensures that power required for the operation of the discharge acceleration device is smaller and the abrasion is lower.

Description

Concrete spreader

Technical field

The utility model relates to a kind of concrete spreader.

Background technology

At present, the concrete spreader of prior art is divided into two kinds, and a kind of is common curtain-type concrete spreader, and another kind is a flood dragon formula material distributing machine; The former only depends on the closure or openness of the discharge door at discharging opening place, hopper below to realize cloth or stop the cloth action; Concrete during cloth in the hopper relies on self gravitation to fall, and as strengthening the cloth amount, just needs to strengthen the opening degree of discharge door; But so make the aperture of discharging opening easily greater than the diameter of pile tube punching block; The concrete that falls very easily is scattering into the pile tube punching block and reaches the matched moulds part outward, and carefully ability matched moulds behind the cleaning pile tube punching block normally carries out otherwise exist the spillage phenomenon to influence subsequent handling; Blanking is closely knit inadequately, cloth efficient is lower so exist, and can't control the problem of concrete quantity delivered effectively; And the latter is the flood dragon that below hopper, is provided with level, and promptly the screw pay-off is delivered to the exit through flood dragon with concrete; Though the material distributing machine of this structure can be controlled the blanking amount accurately; But concrete also is to rely on self gravitation to fall behind the exit, thus still do not solve the loose problem of blanking, and the while flood dragon when delivering concrete; Because the characteristic of concrete viscous attitude; The bigger power that the flood dragon rotation needs, the wearing and tearing of energy consumption and flood dragon are all higher, thereby make use cost higher.

The utility model content

The utility model provides a kind of under the prerequisite that feed opening does not enlarge to above problem, can make blanking rapid speed, blanking more closely knit, the concrete spreader that energy consumption is less and use cost is lower.

The utility model overcomes the above problems used technical scheme: a kind of concrete spreader with following structure is provided; It comprises support and the hopper that is connected with support; The lower end of described hopper is provided with discharging opening, and described discharging opening place is provided with the acceleration blanking device.

After adopting above structure; Compared with prior art; The utility model is because the discharging opening place is provided with the acceleration blanking device, and then under the effect of blanking accelerator, the concrete that falls through discharging opening all has certain initial velocity; The speed that falls is faster, denser when concrete is fallen in the pile tube punching block; And quickening blanking device can be in the unit interval, makes the volume of concrete through discharging opening be greater than concrete volume through discharging opening in the unit interval when falling naturally, so need not to strengthen the purpose that the aperture of discharging opening can realize strengthening load; Moreover quicken blanking device and do not contact with concrete fully again, so concrete is less to the viscous effect of acceleration blanking device, the required power of acceleration blanking device work is also just less, it is less to wear and tear.Therefore the utility model can make blanking rapid speed, more closely knit under the prerequisite that feed opening does not enlarge, and energy consumption is less and use cost is lower.
