Sandy soil screening equipment capable of distinguishing dryness and wetness

Abstract

The invention discloses sandy soil screening equipment capable of distinguishing dryness and wetness. The sandy soil screening equipment comprises a main box body, a screening cavity is formed in themain box body, the upper wall of the screening cavity is provided with feeding ports in a communicating mode, the feeding ports are provided with upward openings and are in bilateral symmetry, and theupper wall of the screening cavity is fixedly connected with a telescopic block located between the left feeding port and the right feeding port. A telescopic cavity with a downward opening is formedin the telescopic block, the left wall and the right wall of the screening cavity are in up-down sliding connection with a primary filter plate, and the telescopic cavity is in up-down sliding connection with a sliding block fixedly connected with the primary filter plate. The left wall and the right wall of the screening cavity are in up-down sliding connection with filter plate fixing plates. The upper end faces of the filter plate fixing plates are rotationally connected with guide slippers which extend upward to be rotationally connected with the upper end face of the primary filter plate. According to the sandy soil screening equipment capable of distinguishing dryness and wetness, dry sand and wet sand are separately screened, so that efficient screening can be conducted, and efficient stirring and dehumidification are conducted on the wet sand in the screening process.

Description

technical field [0001] The invention relates to the related fields of civil engineering, in particular to sand and soil sieving equipment for dry and wet distinctions. Background technique [0002] In civil engineering, sand, as one of the raw materials for laying, is an indispensable tool, but in the process of use, often the sand will be damp due to improper storage of the environment, weather and other factors, and the sand at this time cannot reach Some engineering requirements, but due to the large amount of sand, the dehumidification work will consume more manpower and time. Some existing sand screening equipment is difficult to separate the dry sand from the wet sand, and generally only set up a sieve once. It is difficult to sieve the sand well. The sand and soil sieving equipment with dry and wet distinctions described in the present invention can solve the above problems. Contents of the invention [0003] In order to solve the above problems, this example desi...
