Rapid stone breaking-screening device for building

Abstract

The invention discloses a rapid stone breaking-screening device for a building. The rapid stone breaking-screening device comprises a bottom plate and a breaking bucket, wherein a support is arranged at a bottom of the bottom plate, a plurality of support arms are connected to a sidewall of the breaking bucket, a crank mechanism is rotationally connected to a bottom of each support arm through a bearing, and a mounted bearing is connected to each crank mechanism through a first rotary shaft and arranged on the bottom plate; a driven gear is installed on a first rotary shaft at a left side, a first motor is arranged on the bottom plate, and a drive gear is installed on a motor shaft at a top end of the first motor and engaged with the driven gear; and a second motor is arranged at the centre of a top of the crushing bucket, a second rotary shaft is connected to a motor shaft at a bottom end of the second motor, a crushing blade is installed on the second rotary shaft, and a filter screen is further arranged at a bottom of the breaking bucket. According to the rapid stone breaking-screening device disclosed by the invention, the broken stone is screened through the arrangement of the filter screen; and the stone in the breaking bucket can be driven to swing to increase breaking efficiency, and stone screening can also be accelerated to prevent the filter screen from being blocked through crank structures.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a rapid crushing and screening device for construction stones. Background technique [0002] With the improvement of urbanization, new buildings are built every day. Buildings are inseparable from stone materials in the construction process, and some stone materials are too large to be directly used for construction. It is convenient to use stone materials. [0003] The crushing efficiency of the general crushing mechanism is not high, and the stones cannot be screened during crushing. After crushing, there are still many stones that do not meet the requirements and cannot be used directly, which will cause waste of resources. Moreover, ordinary crushing mechanisms need to manually control the feeding. It is not very convenient. Contents of the invention [0004] The object of the present invention is to provide a rapid crushing and screening device for building stones t...
