Anti-fishing type grating trash cleaning machine

Abstract

The invention discloses an anti-fishing type grating trash cleaning machine. The machine is characterized in that: the machine is arranged in a ditch through arranging a frame at a certain inclined angle, a variable speed drive system which is arranged on the upper part of the frame drives a driving chain wheel to rotate, a drag chain is arranged on the left side and the right side of the frame, rake teeth which are arranged between the left and right drag chain form a revolution crawler belt and can revolute between the driving chain wheel and a bottom support wheel; a back gating which comprises a bottom arc-shaped grid bar and a support member is fixed on the back of the revolution crawler belt; and when revolution is carried out, the rake teeth are inserted into grids of the back gating to clean the back gating. The machine, which allows the back gating to be arranged on the back of the revolution crawler belt, makes a small amount of banded or shredded dirt which is remained on the rake teeth and is difficult to remove when the turning slag cleaning is carried out not be rushed into rear clean water, not enter back clean water and be effectively intercepted by the back gating, so the trash cleaning efficiency is substantially improved, and slag is thoroughly intercepted; and the water crossing area is substantially increased, so trash cleaning requirements of low water level ditches or dry periods can be satisfied.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to an anti-fishing type grid cleaning machine. Background technique [0002] The anti-fishing grid cleaning machine is widely used in the water intake of sewage treatment plants, drinking water intakes, large-scale hydropower stations, river and lake comprehensive treatment projects, rainwater drainage and sewage lifting pumping stations and other facilities. And the sediment is salvaged by the rake teeth and lifted out of the water surface. When the rake teeth rotate to the top and reverse, the dirt is dumped into the dirt hopper, and the water flows through the grille to the rear water purification area. [0003] The main structure of the existing anti-fishing grill decontamination machine is as Chinese patent "CN200920226422.5---a kind of anti-fishing grille machine" and "CN200920246564.8---high-efficiency anti-fishing grill decontamination machine" The disclose...

AI Technical Summary

Problems solved by technology

[0007] The applicant aims at the problems of incomplete interception of dirt, entrained grid slag return channels, chain jams, etc. in the above-mentioned existing anti-fishing type grille cleaning machine, and provides a kind of anti-fishing type grille cleaning machine with reasonable structure, thereby Efficient cleaning, slag cutting is thorough, and reliability is good, especially to meet the cleaning requirements of low water level ditches or dry seasons
