Mechanical device for preparing recycled sand and stone materials by using construction waste particles

Abstract

The invention discloses a mechanical device for preparing recycled sand and stone materials by using construction waste particles. The mechanical device comprises a bottom plate, wherein the front part and the rear part of the upper end of the bottom plate are fixedly connected with vertical plates; the left part and the right part of the upper end of the bottom plate are fixedly connected with aleft side plate and a right side plate respectively; the middle upper part of the right end of the left side plate is movably connected with a first buffer mechanism; the middle upper part of the leftend of the right side plate is fixedly connected with a material guide mechanism; the front part and the rear part of the material guide mechanism are provided with second buffer mechanisms; a flushing mechanism is arranged among the first buffer mechanism, the material guide mechanism and a guide plate; the upper ends of the two vertical plates are fixedly connected with surrounding plates; andthe upper ends of the two surrounding plates are fixedly connected with a protection mechanism. According to the mechanical device for preparing the recycled sand and stone materials by using the construction waste particles, the construction waste can be comprehensively cleaned, the dust removal effect is good, the impact force of the construction waste on a conveying belt is reduced, so that thedevice is not easy to damage.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a mechanical device for producing recycled sand and gravel by using construction waste particles. Background technique [0002] With the rapid development of society, the use of construction waste particles to produce recycled sand and gravel has become an environmentally friendly construction method. Concrete, waste masonry and other wastes are collectively referred to. According to the source classification, construction waste can be divided into engineering dregs, decoration waste, demolition waste, engineering mud, etc.; according to the composition, construction waste can be divided into dregs, Concrete blocks, crushed stones, brick and tile fragments, waste mortar, mud, asphalt blocks, waste plastics, waste metal, waste bamboo and wood, etc., use the material lifting device to lift the construction waste to the crushing device and screening device for product...

AI Technical Summary

Problems solved by technology

[0003] However, it is easy to cause a lot of dust in the process of lifting concrete blocks, crushed stones, and bricks and tiles. The traditional way is to pour water from top to bottom through water pipes, which is not convenient for concrete blocks, crushed stones, bricks, and tiles. If the debris is watered at any angle, the construction waste cannot be fully cleaned, which will affect the dust removal effect. When watering and washing the construction waste, the sewage will easily fly out from the entrance of the construction waste, which will affect the operation of pouring the construction waste into the equipment. The operation is inconvenient, and when concrete blocks, crushed stones, and broken bricks and tiles are directly poured onto the lifting equipment such as the conveyor belt with a cart, the impact force of the concrete blocks, broken stones, and broken bricks and tiles on the conveyor belt is large , easy to cause equipment damage
