Abstract

A concrete hopper comprises a stirring device including rotary shafts arranged on opposite lateral walls of the hopper through bearings and blades arranged on the rotary shafts. The rotary shafts are driven by a motor arranged outside the hopper. Opening ends of two pumping cylinders arrangement in parallel are arranged on one of the other two opposite lateral walls of the concrete hopper. The pumping cylinders are connected with a vacuum pump to generate vacuum in the pumping cylinders. Flanges are arranged on the lateral walls of the hopper opposite to the pumping cylinders, the outer sides of the flanges are connected with conveying pipes. S-shaped swinging pipes arranged below the rotary shafts of the stirring device are located between the inner sides of the flanges and the opening ends of the pumping cylinders. Feeding devices respectively opposite to openings of the pumping cylinders are arranged on the inner walls of the hopper where the flanges are located. The concrete hopper can fully stir all the concrete in the hopper and helps to push the mixed concrete into the pumping cylinders simultaneously, thereby improving work efficiency of the concrete hopper.

Description

A kind of concrete hopper

Technical field

The application relates to the concrete pumping field, particularly relates to a kind of concrete hopper, and it has the concrete pusher.

Background technology

Concrete pump at first will suck the pumping cylinder with concrete, and then squeeze into carrier pipe when pumping of concrete, and concrete stirring mainly leans on original mixing plant to continue to stir.At present, in order to solve the problem low to the suction efficiency of coarse fodder, each concrete pump manufacturer mainly adopts the method for the shape of improving original mixing plant and hopper to reach the purpose of suction efficiency.Each concrete pump manufacturer both domestic and external adopts the method for improving original mixing plant and hopper shape to promote suction property; Though it is more abundant that these methods can make that concrete stirs; But the concrete of feed hopper bottom still can not get good stirring, and concrete pushed carries the power of cylinder still very little.DeGrain after the improvement.

For in the one Chinese patent application of CN2574872Y a kind of mixing plant that is used for concrete pump is disclosed at notice of authorization number; Wherein: adopted two shafts arranged side by side; Shaft is provided with stirring vane, thereby adopts stirring vane that the concrete material in the hopper is stirred.Its main mode that adopts is the number that has increased shaft, therefore, can not fundamentally solve the problem that the suction efficiency of hopper is low and prevent the concrete material segregation.There is following defective in available coagulation earth material bucket:

1. concrete entering pumping cylinder is in the pumping cylinder, to produce pull of vacuum through the pump that links to each other with the pumping cylinder to realize; Thus; Concrete to different compounds, different viscosityes; Then the pump that links to each other with the pumping cylinder is proposed very high requirement, and be difficult to realize concrete is drawn in the pumping cylinder effectively, thereby reduced operating efficiency.

Since concrete in the pumping process mainly through be in the pumping cylinder and with adpting flange that carrier pipe links to each other between S shape swing pipe on mixing plant stir; Therefore; The swing of S shape swing pipe is in the particularly concrete of the S shape swing pipe bottom stirring that can not get continuing of feed hopper bottom, although also can intermittently be stirred to this part concrete.When pumping of concrete, concrete disintegration appears easily, and promptly the aggregate in the concrete (stone etc.) is separated from concrete, is sink to feed hopper bottom.The suction that in the pumping cylinder, is produced can not be inhaled this type concrete fully, and the concrete side that the pumping cylinder is sucked measures less than pumping cylinder volume, thereby causes suction efficiency to reduce.Just as showing in the accompanying drawing 1, the concrete material in feed hopper bottom can not get fully stirring and is easy to produce segregation, is effectively it to be extracted in this pumping cylinder thereby only depend on the suction of pumping cylinder.

Address the above problem; Need start with from two aspects: sucking the concrete while, improve suction efficiency, and do not allow stone to separate with sand, cement through servicing unit by suction; Let the three be mixed into fluid, be convenient to the pumping cylinder and rely on pressure to suck concrete.

Summary of the invention

The application is and addresses the above problem and proposed a kind of concrete hopper; Wherein, Be furnished with mixing plant in this concrete hopper; This mixing plant comprises through bearing and is arranged in the axis of rotation on the hopper two opposite side walls and is arranged on the blade on this axis of rotation that this axis of rotation is driven by the motor in the hopper outside; On one of other two opposite side walls of said concrete hopper, be furnished with the open end of two pumping cylinders that are set up in parallel.The outer end of hopper that is in of two pumping cylinders links to each other with vacuum pump in the pumping cylinder, to produce vacuum; On the hopper side wall relative, be furnished with flange with the pumping cylinder; The outside of this flange links to each other with carrier pipe; Between the open end of the inboard of flange and pumping cylinder, be furnished with S shape swing pipe, S shape swing pipe is in the axis of rotation below of mixing plant.One end of this S shape swing pipe and the peristome of flange can be tightly connected rotationally; Carry out oscillating motion under the effect of the torque of the driving shaft that the other end of S shape swing pipe then can link to each other at the power source with the hopper outside; Thereby alternately combine with two pumping cylinder sealings; So that mixed concrete is driven into the carrier pipe via this S shape swing pipe from the pumping cylinder; Wherein, when a pumping cylinder that does not link to each other with S shape swing pipe was in the concrete state of suction, another pumping cylinder that links to each other with S shape swing pipe then was in the concrete state of discharging.

Wherein, on the hopper inwall of a flange side of living in, be furnished with relative with the opening of pumping cylinder respectively pusher, this pusher drives through motor coupled, that be in the hopper outside.

Preferably, this pusher is the spiral push device of propeller type, and this spiral push device is pushed to it in pumping cylinder that is in suction condition when the concrete that is in the hopper bottom is stirred.

Wherein, opposite with the spiral push device direction of rotation of two pumping cylinders difference positioned opposite, spiral push device also can be arranged to rotate in the same way as required.

Wherein, said spiral push device is arranged in the below of S shape swing pipe, and the rotation of its axis and mixing plant is perpendicular.

Wherein, this spiral push device comprises and is installed on the bucket wall axle that is driven by motor and is installed in the paddle on this.

Alternatively; On the hopper inwall of a flange side of living in, be furnished with relative with the opening of pumping cylinder respectively pneumatic pusher; This pneumatic pusher is through driven compressor coupled, that be in the hopper outside, and with the concrete Linear Driving in corresponding pumping cylinder.

In conjunction with by means of then having solved existing problem in the prior art through the concrete hopper that technique scheme limited; Promptly the whole concrete in the hopper are being carried out the well-beaten while; Be pushed in the pumping cylinder mixed concrete is auxiliary, thereby improved the operating efficiency of concrete hopper.
