Gravelly soil core material blending device

Abstract

The invention relates to a gravelly soil core material blending device, and belongs to the field of water resources and hydropower engineering. The gravelly soil core material blending device comprises a rotary cylinder, and a driving mechanism for driving the rotary cylinder to rotate. The rotary cylinder and the driving mechanism are arranged on a machine frame. A walking mechanism is arranged at the bottom of the machine frame. A bucket is fixedly connected with and arranged on the outer wall of the rotary cylinder. In implementation, the device is operated after soil and gravel are laid, soil and gravel are shoveled up, lifted and dropped, and soil and gravel rotate along with the rotary cylinder and turn in the bucket after being shoveled up; when separated from the bucket to fall, soil and gravel continuously hit the outer wall of the rotary cylinder and continuously hit each other and are mixed together, and then the blending aim is achieved through multiple times of the process; the rotary cylinder advances together with the machine frame, and blending of the whole material stack is completed. The gravelly soil core material blending device is simple in structure, convenient to operate, low in cost and capable of achieving the continuous blending aim.

Description

technical field [0001] The invention relates to a gravel-soil core wall material blending device, which belongs to the field of water conservancy and hydropower engineering. Background technique [0002] High earth-rockfill dam projects often require a large amount of anti-seepage core wall materials. The anti-seepage body of the core wall not only requires good anti-seepage performance, but also has high shear resistance. However, when the source of natural anti-seepage soil is difficult to meet the requirements of the code, it is necessary to modify it by adding gravel to form gravel soil to improve its shear resistance. [0003] At present, the blending of gravel soil core wall materials generally adopts the method of "flat laying and vertical mining". Soil and stone materials are “tiled” by equipment such as dump trucks and bulldozers, and “vertical mining” is carried out by equipment such as front shovel excavators and loaders. Mix soil and stone evenly. However, du...

Problems solved by technology

However, during the blending process of gravel soil materials, only the blending within the effective bucket capacity can be carried out, and the process of turning and lifting the bucket by the excavator takes a long time, and there are problems such as poor blending uniformity and low efficiency
