Gravel screening device for building

Abstract

The invention discloses a gravel screening device for a building. The gravel screening device for the building comprises a shell, a feeding hole is formed in the right side of the upper surface of theshell, the right side of the top of an inner cavity of the shell is fixedly connected with a fixing frame, the fixing frame is movably connected with an inclined plate through a pin shaft, a supporting plate is fixedly connected above the inner wall of the right side of the shell, a buffer spring is fixedly connected to the upper surface of the supporting plate, the other end of the buffer springis fixedly connected to the lower surface of the inclined plate through a spring base, and the left side of base of the inner cavity of the shell is fixedly connected with a first guide column. According to the gravel screening device for the building, a first screening frame, a second screening frame, the first guiding column, a second guiding column, a first guide block, a second guide block, afirst spring, a second spring and a vibration motor are arranged and cooperate with one another, so that the problem that the screening efficiency is low in a construction site is solved; and the fixing frame, the pin shaft, the inclined plate, the supporting plate and the buffer spring are arranged and cooperate with one another, so that the problem that the screening speed is low when a large amount of gravels are directly screened is solved.

Description

Technical field [0001] The invention relates to the technical field of construction equipment, in particular to a sand and stone screening device for construction. Background technique [0002] With the development of society and the continuous advancement of technology, more and more equipment is used by people in life and work, which greatly improves work efficiency and reduces the labor intensity of staff. In construction sites, mixers and cranes The use of rammers and rammers has greatly improved the construction speed and the quality of construction. However, the screening of sand and gravel in the construction site is still manual screening, and artificial sand and gravel screening generally uses a screen. Supported on the ground, people use shovel to sieve. This kind of sand and gravel screening method is labor intensive. Workers feel physical fatigue and arm soreness after screening for a period of time. The existing artificial sand screening efficiency is low and the scr...
