A high-efficiency sand and gravel screening equipment for road construction

Abstract

The invention discloses a high-efficiency gravel screening device for road construction, which comprises a base, a first bracket, a first screen, a second screen and a round bottom plate, the upper surface of the base is fixedly mounted with the first bracket, and the The top of the base is located on one side of the first bracket, and the first screen, the second screen, and the round bottom are arranged equidistantly from top to bottom, and the upper surface of the base is located on one side of the first bracket. The whole set of devices provides the power driving structure. The first screen, the second screen and the center of the circular bottom plate are all fixedly installed with an intermittent propulsion structure that can realize the intermittent push function. The layered disc screening method is adopted, and the motor drives the first The first rotating shaft rotates, and then drives the first screen and the second screen to rotate. By cooperating with the gap brake structure and the intermittent propulsion structure, a stable vibration is generated, which is convenient for the uniform screening of sand and gravel, and effectively solves the problem of using existing equipment. The vibrating motor only vibrates in one direction, which leads to insufficient screening of sand and gravel.

Description

technical field [0001] The invention relates to the technical field of sand and gravel screening equipment, in particular to a high-efficiency sand and gravel screening equipment for road construction. Background technique [0002] In road construction, it is often necessary to use sand and gravel to lay the roadbed, and there are different requirements for the diameter of sand and gravel. When screening sand and gravel, in order to save costs, manpower is often used for screening. In order to reduce the labor intensity of workers, At the same time, the construction efficiency is improved, and the automatic sand screening equipment has further appeared. [0003] In the existing sand and gravel screening equipment, the following problems often occur: the whole set of equipment is driven by multiple motors, which will cause some energy waste, and driven by the vibrating motor, only one direction can be provided. The vibration effect does not provide effective vibration to scr...

Problems solved by technology

[0003] In the existing sand and gravel screening equipment, the following problems often occur: the whole set of equipment is driven by multiple motors, which will cause some energy waste, and driven by the vibrating motor, only one direction can be provided. The vibration effect cannot provide effective vibration to screen the sand and gravel, which will lead to insufficient sand and gravel screening, and some sand and gravel will be excluded before being screened. Insufficient vibration will block the screen, which will affect the normal sand screening progress, and the sand and gravel discharge port is in a fixed position. Due to the complex environment of the construction site, if the position of the discharge port is changed due to the change of the space position, the whole set of equipment needs to be replaced. It is very troublesome to move
