Sand accelerated drying and screening device based on cam transmission structure

Abstract

The invention relates to the technical field of sand screening, and discloses a sand accelerated drying and screening device based on a cam transmission structure. The sand accelerated drying and screening device comprises a box body, wherein a discharging opening is formed in the bottom of the interior of the box body; and a base is fixedly connected to the bottom of the box body. According to the sand accelerated drying and screening device based on the cam transmission structure, sand in a lump is smashed through a stirring roller, and heating and screening of the sand are facilitated; through a gear transmission structure, two sets of cams can be driven by a second motor to synchronously rotate, and therefore synchronous vibration of a heating plate and a filtering plate is achieved, the heating and screening speed of the sand is increased, and the screening efficiency is improved; the flow speed of the sand on the heating plate is reduced through a gear rod, the heating time of the sand is prolonged, and the drying performance of the sand is enhanced; and a buffering base buffers vibration generated by the filtering plate, the situation that the filtering plate is damaged dueto too large amplitude is prevented, and the service life of the machine is prolonged.

Description

technical field [0001] The invention relates to the technical field of sand screening, in particular to an accelerated drying and screening device for sand based on a cam transmission structure. Background technique [0002] In building construction, a large amount of sand is needed. The weight and amount of sand are large, and they are usually placed outdoors directly. After the sand is placed outdoors for a long time, it will absorb the moisture in the air and become damp. When sand is screened, sand with a high water content is easy to form lumps, which cannot be screened well, and it is easy to block the mesh of the screen, resulting in a decline in screening quality. [0003] When screening sand, the existing sand screening device cannot break the wet sand into lumps, and cannot dry the wet sand, causing the sand to block the mesh due to moisture, resulting in a decline in screening quality, and does not have the function of accelerating screening. , Relying on the san...
