Sand screening device for construction site

Abstract

The invention discloses a sand screening device for a construction site. The sand screening device comprises a base, supporting feet, a screening bin, a feeding inlet and a collection box. A shaking motor is fixedly connected with the middle of the lower surface of the base. A rack frame is slidably connected with the upper surface of the base. A half gear is arranged on a shaft extension end of the shaking motor in a sleeving mode. The screening bin is arranged above the rack frame. Sliding plates are fixedly connected with the left side and the right side of the screening bin correspondingly. A guiding rod is fixedly connected with the upper surface of the rack frame. A vibrating motor is fixedly connected with the upper surface of the screening bin. An opening is formed in the bottom ofthe screening bin. An arc screening plate is mounted at the bottom of the screening bin. A stirring shaft is arranged in the screening bin. In the sand screening process, the screening bin moves leftand right, the sand screening efficiency is improved, sand is stirred through stirring blades, thus, sand makes contact with the arc screening plate more sufficiently, the screening efficiency is further improved, the screening bin is driven by the vibrating motor to vibrate up and down, the screening efficiency is further improved, and sand can pass through the arc screening plate advantageously.

Description

technical field [0001] The invention relates to construction equipment, in particular to a sand screening device for a construction site. Background technique [0002] Sand is an important raw material for construction. The sand is salvaged from the river and needs to be screened to separate the sand of different thicknesses. The traditional manual sand screen is to tilt the sand net on the ground, and then pour the sand on the bottom of the sand net. Above, when the sand slides down in the sand net, the sand smaller than the diameter of the gauze passes through the sand net, and the sand larger than the diameter of the sand net is filtered and slides down to the bottom of the sand net. With the step-by-step expansion of infrastructure construction, the demand for sand screening is also increasing. However, the sand screening devices currently on the market are manual, which not only requires a large amount of labor, but also slow processing speed, time-consuming, and low s...
