Abstract

The invention provides a sand and gravel screening device based on machine-made sand production, and relates to the technical field of sand and gravel screening, the sand and gravel screening device comprises a fixed platform, four platform supporting rods are fixedly installed on the surface of the fixed platform, and inclined fixing rods are fixedly installed at the two ends of two of the platform supporting rods correspondingly; a movable screening mechanism is movably mounted among the four inclined fixing rods, and a knocking and falling mechanism is mounted on one side of the movable screening mechanism. And reset springs fixedly installed at the two ends of the movable sleeve column can further enhance the resilience force of a counter weight hammer connecting rod so as to ensure that materials clamped in leakage holes can be knocked out in the process of knocking the rotating cylinder, and therefore when the roller is used for screening gravel, some irregular gravel clamped in meshes of the roller can be cleaned, and the screening efficiency of the roller is improved. Therefore, the meshes of the roller are prevented from being blocked, and the influence on normal screening of the roller is effectively avoided.

Description

technical field

[0001] The invention relates to the technical field of sand and gravel screening, in particular to a sand and gravel screening device based on machine-made sand production. Background technique

[0002] With the rapid development of the construction industry, the demand for sand and gravel is increasing, but the size of the sand and gravel is different, if the selection is not good, it will affect the quality of the project. Screening distinction is used in different occasions. For example, a sand and gravel screening device with application number CN201620942636.2 includes a base, a bracket, a sieve body, and a feeding port. The sieve body is fixed on the base through a bracket. The feeding port is arranged at the upper end of the screen body, and the fine sand and coarse sand outlets are arranged under the screen body. The bottom end of the hydraulic rod is fixed on the base, and the top end of the hydraulic rod is connected with the screen body through th...
