Problems solved by technology

[0003] Purpose of the invention: the present invention provides a step-by-step pouring hopper for large-graded aggregate concrete and a method for pouring concrete using the hopper; the hopper has a simple structure, reasonable design, and is easy to use and operate. The pouring sequence is used to solve the problem that the large-graded aggregate concrete cannot be pumped and the aggregate sinks, so that the aggregates of the large-graded concrete are evenly distributed during the pouring process without delamination

Embodiment Construction

[0025] Such as figure 1 As shown, a step-by-step pouring hopper for large-graded aggregate concrete includes a support plate 1 , a main bucket 2 , an arc gate 5 and a distribution nozzle 6 .

[0026] The bracket plate 1 is fixedly installed on the main bucket 2 to reinforce the structure of the main bucket 2 . The main bucket 2 is a cylinder with upper and lower openings. The outlet below the main bucket 2 is provided with an arc-shaped gate 5, which can block the opening below the main bucket 2, and the bottom of the main bucket 2 is fixedly connected with a distribution nozzle 6, and the lower opening of the main bucket 2 communicates with the distribution nozzle 6. The shaped gate 5 can slide between the slots provided between the distribution nozzle 6 and the main bucket 2 . Along the opening direction of the arc gate 5, the main bucket 2 is sequentially provided with a first partition board 7-1 and a second partition board 7-2 to divide the main bucket 2 into a first ce...

Abstract

The invention discloses a large-grading aggregate concrete step-by-step pouring hopper. The large-grading aggregate concrete step-by-step pouring hopper comprises a main hopper and a bracket plate. Amain hopper is divided into a plurality of chambers by a partition board bin in the main hopper, the chambers can hold different ingredients, the chambers communicate with a material distributing nozzle on the lower portion, an arc-shaped gate is arranged below the main hopper, the arc-shaped gate can slide in a slot seam arranged between the material distributing nozzle and the main hopper, the arc-shaped gate is connected with an arc-shaped gate connecting rod, the arc-shaped gate connecting rod is fixedly connected to a hinge pin, a gear at the tail end of the hinge pin meshes with a motorgear under a motor, and the motor gear drives the hinge pin to rotate to further drive the arc-shaped gate connecting rod to rotate, so that the arc-shaped gate can rotate by a certain angle, and thedischarging of different stock bins is controlled.

Description

technical field [0001] The invention relates to a concrete construction pouring method and device. Specifically, it relates to a step-by-step pouring hopper for large graded aggregate concrete. Background technique [0002] Large graded concrete is often used in engineering. Large-graded concrete refers to the concrete with coarse aggregate with a diameter ≥ 100mm. This kind of concrete has the characteristics of high strength and strong shrinkage resistance. This type of concrete is mainly used in the pouring of large-scale concrete projects such as dams, roadbeds, underground diaphragm walls, and floor transfer floors. Due to the large particle size and weight of the aggregate, which is different from ordinary concrete, there are two problems in the construction and pouring process of this type of concrete: 1. The aggregate particle size of large-graded concrete is too large to be as good as ordinary concrete. Concrete is also stirred and pumped by a mixer; 2. During th...
