Building gravel screening machine having anti-blocking function

Abstract

The invention discloses a building gravel screening machine having an anti-blocking function, relates to the technical field of screening devices and aims to solve the technical problems that screening plates of existing screening equipment are prone to being blocked, repeated screening is needed, gravel different in particle size cannot be screened in one time, and screening efficiency is low. The building gravel screening machine comprises a box, a feeding port and a discharging port are arranged on the box, a scraping plate component and at least two screening plates are arranged in the box, the scraping plate component comprises a first rotating shaft which is vertical, a first driving motor and multiple scraping rods sleeving the first rotating shaft and positioned above the corresponding screening plates, a circulating outlet and a circulating inlet which are matched with the corresponding screening plate are arranged on the box, a material lifting device positioned on the outerside of the box is connected on the circulating outlet and the circulating inlet, and a gravel outlet is arranged at the bottom of the material lifting device. The building gravel screening machine has the advantages that blocking of the screening plates is prevented effectively, clean gravel can be screened in one time while gravel different in particle size can be screened in the other time, andscreening efficiency is high.

Description

technical field [0001] The invention relates to the technical field of screening devices, in particular to a building sand screening machine with an anti-blocking function. Background technique [0002] The process in which the broken material is divided into different particle sizes through one or several layers of sieve surface is called sieving. The screening machine is a vibrating screening mechanical equipment that uses the relative movement between the bulk material and the screen surface to make some particles pass through the screen holes, and divide sand, gravel, crushed stone and other materials into different grades according to the particle size. After the sieving raw material is fed to the screening equipment, the material smaller than the sieve size passes through the sieve hole, which is called the under-sieve product; the material larger than the sieve size is continuously discharged from the sieve surface, called the over-sieve product. On the construction ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is: in order to solve the technical problems that the sieve plate of the existing screening equipment is easy to block, needs to be repeatedly screened, cannot screen sand and gravel with different particle sizes at one time, and has low screening efficiency. A construction sand and gravel screening machine with anti-clogging functions, which can prevent the clogging of the sieve plate, can sieve clean sand and gravel at one time, can sieve various sand and gravel with different particle sizes at one time, and has high screening efficiency.
