Gravel cleaning device for constructional engineering

Abstract

The gravel cleaning device comprises a rack, a cleaning machine body and a gravel conveying belt arranged below a discharging opening of the cleaning machine body, and a water absorption belt transmission mechanism and a material stirring mechanism are arranged above the gravel conveying belt; the shifting mechanism comprises a shifting plate; the water absorption belt transmission mechanism comprises a belt, a water absorption layer is arranged on the surface of the belt, and the water absorption layer can make contact with gravel on the gravel conveying belt and is matched with the gravel conveying belt to enable the gravel to roll. By arranging the water absorption belt transmission mechanism and the material stirring mechanism, the water absorption layer can make contact with gravel on the gravel conveying belt and make the gravel roll in cooperation with the gravel conveying belt, and the gravel makes full contact with the water absorption layer in the rolling process, so that residual water on the surface of the gravel is transferred into the water absorption layer; the water squeezing roller can squeeze out water in the water absorption layer, and finally the water is guided into the cleaning machine through the water guide cylinder, so that the water is recycled, the water consumption of the cleaning machine is reduced, and the utilization rate of water resources is increased.

Description

technical field [0001] The invention relates to a sandstone cleaning device for construction engineering, belonging to the technical field of sandstone pretreatment for construction engineering. Background technique [0002] As a building material, concrete is very important in construction engineering. To some extent, the quality of concrete directly affects the final effect of the entire construction project. Concrete is made of sand, powder and water. The ratio of various components is very important, and the quality of each component itself is also very important. For sand and gravel, the sand and gravel need to be pretreated to a certain extent, mainly for cleaning to remove the soil on the surface of the sand and gravel. Existing washing machines are generally drum-type washing machines, which can discharge materials while feeding, but the sand and gravel will bring out a lot of water when discharging, which has the problems of large water consumption and low utiliza...
