Problems solved by technology

[0003] Because the river sand particles are different in size, it needs to be screened before use. The traditional river sand screening device is a simple device that uses a support rod to support a screening net obliquely, which cannot achieve grading and screening. It requires

Abstract

The invention discloses a river sand screening device for a building. The river sand screening device comprises a barrel. A feeding hopper is arranged at the upper end of the barrel, the lower end ofthe feeding hopper penetrates through the side wall of the barrel and extends into the barrel, and the inner wall of the feeding hopper is fixedly connected with a primary screening net. The upper endthe barrel is fixedly connected with a first supporting seat, and a U-shaped groove is formed in the first supporting seat. A fixing rod is fixedly connected to the side wall of the feeding hopper, and the end, away from the feeding hopper, of the fixing rod is fixedly connected with a rotary shaft. A supporting plate is fixedly connected to the side wall of the feeding hopper, and the supportingplate and the fixing rod are symmetrical. A second supporting seat is fixedly connected to the upper end of the barrel, and the second supporting seat and the first supporting seat are symmetrical. Afirst motor is fixed to the second supporting seat. The river sand screening device is simple in structure, grading screening can be achieved, the time and labor are saved, the screening efficiency is high, and river sand which does not pass through the screening net can be poured out easily after screening.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a river sand screening device for construction. Background technique [0002] River sand is a non-metallic ore with complex composition, smooth surface and high impurity content. River sand particles are smooth and relatively clean. There are many sources, river sand has no smell, sea sand has a salty taste, river sand has made an outstanding contribution to the construction industry, but sea sand is the opposite, sea sand is often mixed with shells and salt, most sea sand contains excessive chloride ions, which will corrode The steel bars in reinforced concrete will eventually lead to the destruction of the building structure, which will shorten the safe service life of the building to a certain extent. After drying and screening, river sand can be widely used in various dry powder mortars, such as thermal insulation mortar and bonding mortar And plastering morta...
