Abstract

A concrete pump hopper without mixer comprises hopper body (1) and S tube (2) arranged in the cavity of the hopper (2). Two left and right material pipe orifices cooperated with the feed inlet of the S tube (2) are mounted at the lower part of the posterior wall of the hopper. The discharge end of the S tube (2)is positioned at the anterior wall of the hopper through a bearing block ands feed end is combined with the swing mechanism of the S tube through a connecting piece. The back surface shape of the hopper located on the lower part of the swing zone of the S tube (2) is a continuous hood face which is similar to the swing trace of the S tube (2). The hopper of the utility model guarantees the pouring quality of the concrete mixture mainly by swinging the S tube to prevent isolation or solidifying of the concrete mixture. Because the back surface shape of the hopper located on the lower part of the swing zone of the S tube (2) adopts a continuous hood face that is similar to the swing trace of the S tube (2) which can help the concrete mixture pass through the two left and right material pipe orifices mounted at the lower part of the posterior wall glidingly and enter the pumping device, dead angle that can not be mixed does not exit and the feed is clean.

Description

The concrete pump hopper of no agitator

Technical field

The utility model relates to a kind of transmission and concrete transmission device, relates to a kind of concrete pump hopper that does not have agitator specifically.The hopper that this hopper can be used as concrete pumps such as stationary concrete pump, towed concrete pump, truck mounted concrete pump, concrete mixer uses.

Background technology

Concrete pump is to be used for to building, and particularly the high-rise building delivering concrete mixes and stirs the special equipment of material.Working method is as follows: the commercialization concrete of being produced by concrete batching and mixing tower, station mixes and stirs material and delivers to the building site via concrete delivery truck, and concrete is mixed and stirred material pour in the hopper of concrete pump, by concrete pump the concrete in the hopper is mixed and stirred material and be sent to the on-the-spot use of cast.

The concrete pump hopper of prior art comprises hopper body and the S pipe that is arranged in the hopper cavity, below the rear wall of hopper, be provided with left and right two material mouths of pipe that match with the charging aperture of S pipe, left and right two material mouths of pipe are connected with concrete pump by two transmission and concrete transmission cylinders that are positioned at the hopper rear, the discharge end of described S pipe is installed in by bearing support on the antetheca of hopper, and its feed end combines with S pipe swing mechanism by connector.Produce segregation or solidify suspending when carrying at course of conveying for the concrete of avoiding injecting the concrete pump hopper mixes and stirs material, and having influence on the quality that concrete mixes and stirs material, mostly the concrete pump hopper of prior art is to adopt at the hopper inner chamber generation that the method for agitator is stopped above-mentioned phenomenon is set.

Mostly common agitator is to be made up of moving device main shaft of the stirring that has stirring vane and hydraulic oil motor.Mix and stir stone in the material for fear of concrete and in whipping process, produce " getting stuck " accident with the bottom surface of hopper, must leave certain clearance between stirring vane and hopper bottom surface, and the concrete that is positioned at this gap mixes and stirs that material will be trapped in this gap and no longer continue to participate in stirring, and forms and stirs the dead angle.For avoiding solidifying the operate as normal that directly has influence on the concrete pump hopper because of the concrete that is detained mixes and stirs material, operating personnel must mix and stir material to the concrete that is detained and clear up timely, and this has just strengthened operating personnel's workload virtually.

In addition, because the hopper of prior art not only need be installed a series of component such as hydraulic oil motor, blade, main shaft during fabrication, in the design process of its hopper, also to consider the problem that does not interfere between mixing component and housing, consequently cause the increase of hopper shaped design difficulty, in making process, mostly the weld seam of its welding is between curved surface or the intersection of plane and surface intersection, to the technological requirement height of processing and manufacturing, manufacturing processing technic complexity and cost of production certainly will have also just been increased.

Summary of the invention

A kind of structure that the purpose of this utility model designs at existing weak point in the above-mentioned prior art just is more reasonable, process for machining and manufacturing is simple relatively, and can effectively avoid concrete to mix and stir the concrete pump hopper of the no agitator that material is detained in hopper.

The purpose of this utility model can realize by following technique measures:

The concrete pump hopper of no agitator of the present utility model comprises hopper body and the S pipe that is arranged in the hopper cavity, is provided with left and right two material mouths of pipe that match with the charging aperture of S pipe below the rear wall of hopper.The discharge end of described S pipe is installed in by bearing support on the antetheca of hopper, and its feed end combines with S pipe swing mechanism by connector; The hopper bottom shape that wherein is positioned at below, S pipe amplitude of oscillation zone for and the similar continuous curve surface of S pipe swinging track, and be provided with at the concave bottom place of hopper bottom surface and be used to clear up the bucket drain hole at the end.

Described S pipe swing mechanism by the balance staff that combines with the S pipe, be installed in the swing arm of balance staff rear end and be positioned at the swing arm both sides and two oscillating oil cylinders combining with the swing arm upper end are formed.For the swing that makes the S pipe has enough agitating functions, the utility model has redesigned the installation site of oscillating oil cylinder on the hopper rear wall, change the angle between oscillating oil cylinder and the swing arm into 6 °～10 ° by 17 °～18 ° of prior art, increased the shaking moment value.

Hopper of the present utility model mainly is to utilize swing S pipe to prevent from the segregation of concrete material or solidify to guarantee that concrete mixes and stirs the casting quality of material; Because being positioned at the hopper bottom shape of below, S pipe amplitude of oscillation zone has adopted and the similar continuous curve surface of S pipe swinging track, can make concrete mix and stir material is provided with left and right two material mouths of pipe and enters pumping installations below deadweight and S pipe are swung under the double action glibly by rear wall, there is not the dead angle that can't stir in the hopper cavity shape, feeding is clean, and this mixes and stirs the problem that material is detained the end of struggling against with regard to fundamentally having solved concrete.

In addition, because the utility model has saved agitator of the prior art, the corresponding a series of component such as hydraulic oil motor, blade, stirring main shaft that also just saved, not only reduced the supporting cost of product, simultaneously make that also the planform of hopper is simplified, not only material-saving also makes butt welding process be simplified.Simultaneously because the installing hole of installation and processing agitator main shaft on the left side plate of hopper again, so the whole processing cost of making is minimized.
