Automatic sealing cover of screening machine

Abstract

The invention relates to an automatic sealing cover of a screening machine and is applicable to the field of machinery. The fixed cover plate replacing the sealing cover of the screening machine is installed on the upper portion of the screening machine and comprises a cross beam, a longitudinal beam and a door body, the cross beam and the longitudinal beam are combined with each other, the door body is hinged to the longitudinal beam through a hinge, the door body comprises a left cover body and a right cover body which are opened and closed through the hinge, and a hydraulic station is installed on the longitudinal beam and pushes the cover bodies in the door body to conduct overturning opening and closing movement through a hydraulic push rod. The hydraulic station is controlled by the electric control cabinet, after the cover body is opened, the safety supporting device arranged below the cover body in a linkage mode moves along with the cover body, and the danger caused by falling of the cover body due to pressure failure of the hydraulic station or the hydraulic push rod is prevented. The screening machine is simple in structure and convenient to use, maintenance personnel can conveniently enter the screening machine to maintain or replace parts, the labor amount of workers is greatly reduced, the working efficiency is improved, internal faults of the screening machine can be conveniently found in time, and normal production is guaranteed.

Description

technical field [0001] The invention relates to an automatic sealing cover of a sieve machine, which is particularly suitable for an automatic sealing cover of a sieve machine used in a sieve machine in industrial production, and belongs to the field of mechanical equipment. Background technique [0002] Screening equipment is widely used in electric power, chemical, coal, mining and other industries for material classification. Due to the requirements of environmental protection management in recent years, many new projects, especially in the power, chemical and other industries, require screening equipment to be equipped with sealing devices. The traditional sealing device is made of steel plate to make the box structure, and the upper cover is generally fixed to the surrounding frame by bolts. The sieve plate is a vulnerable part of the sieve machine and needs to be replaced regularly. In normal use, it is also necessary to clean the sundries frequently. First, the seali...

Problems solved by technology

The sieve plate is a vulnerable part of the sieve machine and needs to be replaced regularly. In normal use, it is also necessary to clean up the sundries frequently. First, the sealing cover must be opened. The cleaning personnel or testing personnel cannot directly enter the inside of the sieve machine, so the detection accuracy is low. , At the same time, several people need to use long tools to work remotely during the cleaning operation, which not only delays production, but also consumes labor
