Shaking type sand screening device

Abstract

The invention discloses a shaking type sand screening device. The device comprises a stirring chamber, a screening barrel and a screening chamber, wherein a motor is arranged at the upper end of the stirring chamber, and the output end of the motor is fixedly connected to a rotating shaft; the rotating shaft passes through the stirring chamber and enters the screening chamber; a movable plate is fixedly mounted on the rotating shaft in the stirring chamber, and a fixed plate which is fixedly connected to the sidewall of the stirring chamber is arranged below the movable plate; a supporting plate is fixedly mounted in the screening chamber; the screening barrel is in sliding connection with the supporting plate; the lower end of the rotating shaft extends into the screening barrel and is fixedly connected to an arc-shaped scrapping plate. According to the device, the movable plate and the fixed plate are matched to intermittently charge sand, so that the problem that a large amount of sand is synchronously charged into the screening chamber to influence the screening efficiency can be effectively prevented; the screening barrel is driven by a pushing rod to move leftwards and rightwards to screen; and meanwhile, the bottom part of the screening barrel is scrapped through the arc-shaped scrapping plate arranged in the screening barrel, so that screening meshes can be prevented from being blocked by sand, and a screening plate can work normally.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a shaking type sand screening device. Background technique [0002] Sand is an essential basic raw material in the field of construction. There are many impurities in the sand, such as gravel, garbage, etc., and the sand in the sand is also divided into different grades for different purposes. The required sand particle size grade different. Therefore, the sand needs to be screened before using it. The sand inside the sand pile is easy to agglomerate due to the high humidity or the presence of rainwater after rain. The current sand screening equipment generally does not have a stirring function, which reduces the sand screening efficiency, and the screen is fixed during the screening process. , the sand screening efficiency is low, which increases the labor intensity of workers and reduces the work efficiency. During the working process, some sand is easy to get stuck in t...

Problems solved by technology

The sand inside the sand pile is easy to agglomerate due to the high humidity or the presence of rainwater after rain. The current sand screening equipment generally does not have a stirring function, which reduces the sand screening efficiency, and the screen is fixed during the screening process. , the sand screening efficiency is low, which increases the labor intensity of workers and reduces the work efficiency. During the working process, some sand is easy to get stuck in the screen holes of the sieve plate, which will block the sieve holes in the long run, resulting in the failure of the sieve plate.
