Energy-saving and environment-friendly screening device for constructional engineering construction building material gravel

Abstract

The invention discloses an energy-saving and environment-friendly screening device for constructional engineering construction building material gravel. An upper rail and a lower rail with the same structure are arranged in the machine body; a first material passing screen is borne on the upper rail and the lower rail, and a second material passing screen is borne on the two lower rails. An inclined panel with a material leaking hole is arranged in the middle of the first material passing sieve; an outflow square hole is formed in the right side of the first material passing sieve; sliding plates inclining towards the inner side of the middle part are arranged on the left and right sides of the bottom of the first material passing screen; a driving support is installed on the left side ofthe first material passing screen, a linkage rod and a driving motor are arranged in the driving chamber, the linkage rod is connected with a driving disc through a power rod, the power rod is hingedto the midpoint of the linkage rod and the outer circle side of the driving disc, and a second driving support connecting plate penetrates through the left side wall of the machine body and then is connected with the linkage rod. By arranging the first material passing screen, the second material passing screen and the driving chamber, gravel can be screened conveniently, and the beneficial effectof being environmentally friendly is achieved. The screening device is suitable for being widely applied to gravel screening.

Description

technical field [0001] The invention relates to the technical field of screening devices for sand and gravel energy-saving and environment-friendly construction materials for construction projects, in particular to an energy-saving and environment-friendly screening device for construction materials and sand for construction projects. Background technique [0002] When people sieve sand and gravel, they mainly filter the sand and gravel filter material by shaking the sieve with both hands. The sieving efficiency is not high, and dust is easily generated during the sieving process, which will cause great damage to the health of the operator, and the environmental protection is poor. The screening device for sand and gravel environment-friendly building material sand and gravel overcomes the shortcomings of manual screening by people, low screening efficiency and serious dust pollution in the prior art.
