Efficient sand screening device for bridge construction

Abstract

The invention discloses an efficient sand screening device for bridge construction, and relates to the technical field of construction machinery. The efficient sand screening device comprises a screening chamber, the screening chamber is internally provided with a screening groove used for screening sand, the bottom of a swinging plate is provided with a scraping mechanism used for scraping the screening groove, a supporting plate used for supporting the screening groove is rotationally installed in the screening chamber, and a rotating mechanism used for driving the screening groove to rotateis arranged on the screening chamber. According to the efficient sand screening device, the scraping mechanism is driven by the swinging mechanism to carry out transverse reciprocating motion, a scraping plate in the scraping mechanism can keep the abutting connection with the inner bottom surface of the screening groove under the elastic action of a reset spring, so that the dispersing effect onthe sand and the scraping cleaning effect on sieve pores in the screening groove are achieved, the blockage of the sieve pores is avoided, the screening efficiency of the sand is improved, the rotating mechanism can drive the screening groove to rotate, so that the dispersing effect of the scraping mechanism can be obtained at different positions in the screening groove, and the screening efficiency of the sand is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a high-efficiency sand screening device for bridge construction. Background technique [0002] Bridge engineering refers to the work process of bridge survey, design, construction, maintenance and verification, as well as the science and engineering technology to study this process. It is a branch of civil engineering. The development of bridge engineering mainly depends on the impact of transportation on it. need. The sand used during the construction of the bridge needs to be sieved to obtain sand with a particle size that meets the requirements of the construction code. [0003] The patent with authorized notification number CN205833598U discloses a sand screening device, which includes a frame, a flat roller screen drum, a sand screen net and a hopper; The two sides of the cylinder are respectively equipped with driving devices that can rotate the roller scre...

Problems solved by technology

[0003] The patent with authorized notification number CN205833598U discloses a sand screening device, which includes a frame, a flat roller screen drum, a sand screen net and a hopper; The two sides of the cylinder are respectively equipped with driving devices that can rotate the roller screen cylinder; the output shaft of the single-phase motor is connected with a coupling, and a rotating shaft is arranged between the two couplings on both sides of the roller screen cylinder, and the rotating shaft passes through the roller. Screen drum; there is a crushing device inside the roller screen drum, and the crushing device is fixed on the rotating shaft; although this device can screen the sand, the dispersion of the sand in the sand screening process is poor, which is likely to cause blockage of the screen hole, and the sand The screening efficiency is low, therefore, a high-efficiency sand screening device for bridge construction is now provided to solve the above technical problems
