Rapid stone breaking-screening device for building

Abstract

The invention discloses a quick crushing and screening device for building stones, which comprises a bottom plate and a crushing barrel. A bracket is arranged at the bottom of the bottom plate. A plurality of support arms are connected to the side wall of the crushing barrel. A crank mechanism is connected to the bottom of the support arm through bearing rotation. The crank mechanism A bearing with a seat is connected through the first rotating shaft, and the bearing with a seat is arranged on the bottom plate; a driven gear is installed on the first rotating shaft on the left side, a first motor is arranged on the bottom plate, and a driving gear is installed on the motor shaft at the top of the first motor. The gear meshes with the driven gear; the center of the top of the crushing barrel is provided with a second motor, the motor shaft at the bottom of the second motor is connected to a second rotating shaft, a crushing blade is installed on the second rotating shaft, and a filter screen is arranged at the bottom of the crushing barrel. The invention screens the crushed stones by setting a filter screen, and the crank structure can not only drive the rocks in the crushing bucket to shake, improve the crushing efficiency, but also speed up the screening of the stones and prevent the filter screen from being blocked.

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...
