Abstract

The invention relates to the technical field of construction equipment, in particular to a sand screening device. The sand screening device comprises a screening frame, wherein a plurality of layers of separating screens are arranged at the upper end of the screening frame and detachably connected with the screening frame, a sand recycling box is arranged at the bottoms of the separating screens, a groove is formed in the bottom of the sand recycling box, and the groove is used for fixing the sand recycling box when a forklift is transferred. According to the sand screening device, the multiple layers of separating screens are arranged at the upper end of the screening frame, the multiple layers of separating screens are detachably connected with the screening frame, the separating screens are taken down by adopting the structure, then sand remaining on the separating screens after screening can be recycled, and the sand recycling efficiency is improved; the sand recycling box is arranged at the bottoms of the multiple layers of separating screens, the groove is formed in the bottom of the sand recycling box, and the groove is used for fixing the sand recycling box when the forklift transfers, separated sand can be transferred in time conveniently by adopting the structure, and therefore the sand screening efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a sand screening device. Background technique [0002] When preparing concrete, these two factors (sand particle gradation and sand thickness) should be considered at the same time. Controlling the particle gradation and thickness of sand has great technical and economic significance, and they are important indicators for evaluating sand quality. The particle gradation of the sand is represented by the gradation area, and the thickness of the sand is represented by the fineness modulus. [0003] Therefore, it is usually necessary to screen the sand before preparing concrete. The sand screened by the existing sand screening device is usually directly discharged on the ground, and then transferred by a transfer device, which affects the sand screening efficiency. Contents of the invention [0004] The purpose of the present invention is to overcome the deficienci...
