A method for installing a batching bin under a mixer

Abstract

The invention discloses an installation method of blending machine underneath mixing tanks. The method comprises the following steps: a field is drilled down before installation to form rectangular pits, the height of the rectangular pits is determined according to the dimension of the mixing tanks, rubble concrete walls and reinforced concrete cover plates are poured, and the bottoms of the mixing tanks undergoes concrete hardening; mixing tank reservation ports are reserved in the cover plate pouring process according to the dimension of the outer opening of a separate mixing tank, a distance between two mixing tanks is determined according to the distance of stacking tanks, and a foursquare V-shaped funnel is formed after installing the mixing tank; a conveyor belt is arranged under the mixing tank, and the length of the conveyor belt allows aggregates to be conveyed to a blending machine; and stacking tanks are constructed near the mixing tanks in a partition manner to directly isolate every mixing tank, the separate mixing tank is arranged underneath the terminal of the stacking tank, and back walls are constructed at the back sides of the mixing tanks to form one stacking tank corresponding to one mixing tank. The method has the advantages of construction cost saving, production efficiency increase, stable ratio of a mixture, and construction quality guaranteeing.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a bottom-mounted installation method for a batching bin of a mixer. Background technique [0002] In the highway engineering construction industry, the mixing machines suitable for production mainly include: asphalt mixture mixer, cement stabilized soil mixer and cement concrete mixer. It consists of three major parts: machine and mixer. In the previous installation schemes, the batching machine, main engine and stockyard were built on the same level according to the factory design of the mixer manufacturer (such as figure 1 , 2 ), it is necessary to build a 2-3-meter-high feeding platform close to the batching warehouse, and the loader needs to crawl the slope of the 5-10-meter-long and 2-3-meter-high feeding platform for loading. The traditional installation scheme has the following deficiencies: [0003] 1. In order to meet the production requirements, a large nu...

Problems solved by technology

[0003] 1. In order to meet the production requirements, a large number of loaders are required. Taking the 4000-type asphalt mixing plant as an example, 3-4 50-type loaders are required for full-load production, and the equipment costs are high;

[0004] 2. During the production process, the loader climbs up the slope of the material platform to load materials. The driver needs to step on the accelerator to climb the slope, which consumes a lot of fuel and wears heavily on the machine, and the hopper is not easy to fill, which increases the cost;

[0005] 3. After the loading of the loader is completed, the vehicle reverses downhill and continues to shovel the material into the batching bin. This process has certain potential safety hazards, especially at night.

[0006] 4. There is a gap between the loading platform and the batching bin, and the aggregates are easy to leak into the batching bin, causing the conveyor belt to be stuck, and because the space under the bin is small, manual cleaning is difficult;

[0007] 5. When the loader climbs up the material platform, the front is high and the rear is low. The driver is driving the machine in the upward position, and the sight line is quite poor. The distance between the upper hopper and the batching bin is not accurate. The phenomenon on the other side of the batching bin;

[0008] 6. Most of the batching bins are integrally installed, and the interval between each bin is small. When the loader loads, the aggregates at all levels are easy to mix, which affects the stability of the mixing ratio of the mixture.
