Efficient building sandstone screening device

Abstract

The invention discloses an efficient building sandstone screening device which comprises a feeding hopper. A feeding pipe is arranged at the lower end of the feeding hopper; supporting columns are symmetrically arranged on the left side and the right side of the feeding hopper; supporting sleeves are arranged at the lower ends of the supporting columns in a sliding and sleeving manner; supportingblocks are arranged at the lower ends of the supporting sleeves; rollers facilitating device transportation are arranged on the supporting blocks; buffer springs are arranged inside the supporting sleeves, and connect and fix the supporting sleeves and the supporting columns; a buffer mechanism is arranged to effectively improve the vibration resistance of the device; a connecting ring is arrangedbelow the feeding hopper; a screening plate is arranged at the upper end of the connecting ring, and is cone-shaped; the cone-shaped tip is corresponding to the discharging pipe in position; a collecting hopper is arranged at the lower end of the connecting ring; and a discharging pipe is arranged at the lower end of the connecting hopper. The efficient building sandstone screening device is simple and reasonable in structure, convenient to carry, high in vibration resistance, and high in practicability, and eliminates defects in an existing device.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a high-efficiency construction sand and gravel screening device. Background technique [0002] Construction machinery is the general term for machinery and equipment used in engineering construction and urban and rural construction. It is composed of stress machinery, decoration machinery, high-altitude operation machinery and other machinery. [0003] Sand and gravel will be screened during construction, so screening and processing devices will be used. At present, the existing sand and gravel screening and processing devices on the market only pass through a single screen when screening sand and gravel. Screening, this will lead to incomplete screening of sand and gravel, so that the screening quality of sand and gravel is reduced. [0004] In order to solve the above problems, a high-efficiency building sand screening device is now provided. Contents of the ...
