Sand classified screening device used for building engineering

Abstract

The invention discloses a sand classified screening device used for building engineering. The sand classified screening device comprises a device body, a lubricating mechanism, a cleaning mechanism and a vibration reduction mechanism. A classified screening box is arranged in the device body. A sliding sleeve is arranged on one side surface of the classified screening box, and a sliding rod is arranged on the surface of the inner side of the device body. The sliding rod penetrates the sliding sleeve and is connected with the device body. The lubricating mechanism is located at the connecting position of the sliding rod and the sliding sleeve. The lubricating mechanism comprises a casing pipe, the casing pipe is located on the surface of the inner side of the sliding sleeve, the sliding rodpenetrates the casing pipe, and a sponge casing ring is arranged in the casing pipe. Due to the arranged casing pipe, supporting and limiting of the classified screening box during screening are ensured through sliding between the sliding rod and the sliding sleeve, and meanwhile the work efficiency of the device is improved; due to the arranged sliding rod, a diversion effect of a diversion plate on sand obtained after screening is ensured, and the work quality of the device is improved; and due to an arranged vibration reduction limiting plate, stability of the device is better improved, and therefore the service life of the device is prolonged.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a sand classification and screening device for construction engineering. Background technique [0002] Sand refers to fine stone particles, or something shaped like sand. The thickness of sand refers to the average thickness of sand particles of different particle sizes mixed together. It is usually divided into coarse sand, medium sand, and fine sand. Therefore, construction The previously used sand needs to be dried, graded and screened to ensure the quality of the construction. [0003] However, there are still some disadvantages in the existing construction sand grading and screening device. After the device has been in operation for a long time, dust will fall on the sliding gap between the sliding rod and the sliding sleeve, which will easily block the sliding of the sliding sleeve on the sliding rod. After the device has been in operation for ...

Problems solved by technology

[0003] However, there are still some disadvantages in the existing construction sand grading and screening device. After the device has been in operation for a long time, dust will fall on the sliding gap between the sliding rod and the sliding sleeve, which will easily block the sliding of the sliding sleeve on the sliding rod. After the device has been in operation for a long time, sand tends to remain on the surface of the deflector, making it inconvenient to clean it. Also, when the device vibrates due to operation, the device cannot absorb the force generated by the vibration, making the device prone to shaking. For this reason, we Propose a sand classification and screening device for construction engineering
