Abstract

The invention provides a civil-engineering stone sand screening device convenient to maintain. The screening device comprises a storage bottom plate, a left support, a right support, a material guideoutput frame structure, a temporary storage hopper, a material screening frame structure, a material injection frame structure, an adjustable lead-out frame structure, a storage hopper, grips, an installation frame, a conveying switch, a vibrating switch, a dust-proof cover and a fixed lug plate, wherein the left support and the right support are respectively arranged on the left side and the right side of the upper part of the storage bottom plate through bolts. According to the screening device, the cross section of a rubber buffer sleeve is set to be tapered, so that the rubber buffer sleeve is beneficial to play a buffer function on stones falling downwards during use, and accordingly a large number of stones are prevented from colliding with the ground, smashing and ejecting to one side; and a rotary baffle plate is connected with the outer side of a fixing rod in a shaft manner and is arranged on the inner side of a transverse frame at the same time, so that the rotary baffle plate can be conveniently broken off from the lower side of a discharging pipe according to requirements during use, and accordingly gravel can be conveniently controlled to be led out from the lower side of the discharging pipe.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a maintenance-friendly civil stone sand screening device. Background technique [0002] Civil engineering generally refers to civil engineering, and civil engineering refers to the planning, construction and maintenance of all infrastructure related to water, soil and culture. The current general civil engineering projects include: housing, roads, water, drainage, flood control and transportation. Most of the civil engineering mentioned today generally refers to minor civil engineering, including the primary construction of residences, public buildings, structures, etc. Such as precipitation, earth excavation, foundation laying, pouring of columns, beams, slabs and walls and other maintenance structure pouring and masonry projects and supporting steel bars, simple decorations, etc. In the field of civil engineering, when using raw materials such as stone an...
