Flap gate for scraper

Abstract

The invention discloses a flap gate for a scraper and belongs to the technical field of gates. The flap gate for the scraper comprises a top plate flush with the bottom face of the scraper. Gate plateholes are formed in the top plate, and two oppositely-opened gate plates are symmetrically hinged to the top plate. The two gate plates are flush with the top plate to seal the gate plate holes. Limiting rings are symmetrically arranged on the outer sides of the two gate plates with the gate plate holes as center lines, and the limiting rings are perpendicular to the gate plates. Corresponding long-strip-shaped holes are formed in the two limiting rings, and crankshafts are inserted into the long-strip-shaped holes. Connecting rod journals of the crankshafts are inserted into the long-strip-shaped holes, and main journals of the crankshafts are hinged to hoardings arranged on the other side of the top plate. The main journals are hinged to a linear driving mechanism through fixedly-connected connecting rods, the other end of the linear driving mechanism is hinged to the hoardings, and rotation of the crankshafts controls opening and closing of the gate plates. The flap gate has the advantages that unloading is clean, and no residue exists.

Description

technical field [0001] The invention belongs to the technical field of gates, in particular to a flap-type gate for a scraper machine. Background technique [0002] The scraper series products are widely used in metallurgy, building materials, electric power, chemical industry, cement, port, wharf, coal, mining, grain and oil, food, feed and other industries and departments. The scraper machine is a kind of continuous transportation equipment that conveys bulk materials by means of moving scraper chains in a closed rectangular section shell. When conveying materials, the scraper chains are all buried in the materials, so it is called It is a scraper machine, which has simple structure, good sealing performance, convenient installation and maintenance, and flexible process layout. It can not only transport horizontally, but also transport obliquely or vertically. It can be used alone or in combination with multiple machines, and can be fed at multiple points. It can also unl...

Problems solved by technology

[0003] At present, the scraper machine is widely used in the grain transportation industry. The bottom of the scraper machine is generally provided with a groove for installing the gate. Installing the gate in the groove can realize the function of unloading on the scraper machine. Due to the variety of grain In the process of transporting the grain into the warehouse using the scraper machine, if the unloading is not clean, it is easy to mix different types of grain together. At the same time, during the grain transportation process, some grain particles fall through the gap because the unloading gate is not tight enough. Infrequently opened granaries are prone to mildew and deterioration, seriously affecting grain quality and safety
