Sand sieving device for building operations

Abstract

The invention discloses a sand sieving device for building operations. The sand sieving device for building operations comprises an operation rack, wherein a storage conical barrel is fixedly mountedon the upper portion of the operation rack; a collecting groove is fixedly formed in the bottom of the inside of the operation rack; a transmission sliding rod penetrates in the operation rack in a horizontal sliding manner; a driving motor is fixedly mounted on the back surface of the operation rack; a hinge pin which is abutted to the inner surface of a limiting transmission collar is fixedly mounted on the front surface of the transmission sliding rod in a penetrating manner; a second pull rope is wound on a second fixed pulley; an eccentric rotating wheel drives the limiting transmission collar to rotate eccentrically; the limiting transmission collar drives the transmission sliding rod to move back and forth in the left-right direction through the hinge pin; the eccentric rotating wheel drives the sieve plate to vibrate vertically; by abutted cooperation of a lower transmission block and an upper transmission block, the sieve plate vibrates back and forth in the left-right direction, the sieve plate drives sand thereof to vibrate fully, sieving of the sand is accelerated, by sliding of a first sliding plate and a second sliding plate, the sand in the storage conical barrel isfed into the sieve plate intermittently, and the sand is fully sieved by the sieve plate.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a sand screening device for building construction. Background technique [0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into real objects at designated locations. It includes basic engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place where the construction works is called "construction site" or "construction site", also called construction site. [0003] In the process of building construction, sand is one of the most commonly used building materials. In actual use, due to the technical requirements of building construction, it is necessary to screen the sand to obta...

AI Technical Summary

Problems solved by technology

[0003] In the process of building construction, sand is one of the most commonly used building materials. In actual use, due to the technical requirements of building construction, it is necessary to screen the sand to obtain finer sand with smaller particle sizes. The current The sand screening device for construction construction has a poor screening effect on sand. Most of the screening process requires manual feeding, which requires a large amount of labor and low efficiency, which is not conducive to the current construction needs.
