Abstract

The invention provides a sand screening mechanism which comprises a screen mesh, the two ends of the screen mesh are respectively connected with two sets of transmission devices, each set of transmission device comprises a connecting rod A, one end of the connecting rod A is fixed on a main shaft, the other end of the connecting rod A is hinged with one end of a connecting rod B, the other end of the connecting rod B is hinged with one end of a connecting rod C, and the other end of the connecting rod C is fixedly connected with one side of the screen mesh; and the main shaft is arranged on two support plates by a bearing, and the screen mesh is arranged between the two support plates and hung on the support plates by a rope. The sand screening mechanism provided by the invention has the advantages of simpleness in operation, low technical requirements, small occupied area, low investment cost, and capability of effectively enhancing the construction efficiency and saving a large number of labors, therefore, the sand screening mechanism is especially suitable for the field of small and medium-sized constructional engineering.

Description

technical field [0001] The invention belongs to the technical field of construction machinery and equipment, and in particular relates to a sand screening mechanism. Background technique [0002] Sand screening machine is a professional machine for sand screening in sand field and construction site. At present, the sand screening machines on the market are all large-scale sand screening machines, which have complex structure, strong operability, large volume, large dedicated space, and high investment requirements for the construction industry. Most of them are used for sand washing. mining sand. Construction sand screening is mainly for screening sand grains. Due to the small construction site, large-scale sand screening machines are not suitable for construction sites. At present, construction site sand screening is mainly performed manually by using sand screens, which is labor-intensive and low-efficiency. Contents of the invention [0003] The object of the present ...
