Abstract

The utility model provides a rotation assisting device of a dust cleaning machine. The rotation assisting device consists of a boundary beam of the dust cleaning machine, a rail, a grid bar of the dust cleaning machine, a cross beam of the dust cleaning machine, a tooth rack of the dust cleaning machine, a bearing base, an auxiliary grid shaft, a limiting block and an auxiliary grid bar. The rotation assisting device is characterized in that the bearing base is fixedly connected at the bottom of the boundary beam of the dust cleaning machine and protrudes towards the front direction of a grid body; the auxiliary grid shaft is mounted on the bearing base through bearings at the both ends; the auxiliary grid shaft is fixedly connected with the auxiliary grid bar upwards; the auxiliary grid bar is separated from the tooth rack of the dust cleaning machine; the tooth rack of the dust cleaning machine is arranged on a rotary chain in the rail; the rail is fixedly arranged on the boundary beam of the dust cleaning machine and the cross beam of the dust cleaning machine; the upper part of the auxiliary grid bar abuts against the grid bar of the dust cleaning machine in an inclined manner through own weight; the auxiliary grid bar randomly rotates along the auxiliary grid shaft; and the limiting block is arranged on the bearing base. The rotation assisting device provided by the utility model has the beneficial effects as follows: a rotation space of the tooth rack of the dust removing machine is eliminated by using the auxiliary bar of the dust cleaning machine, so that dust with a large size can be prevented from entering a working unit; and the operation security and reliability of the rotary dust cleaning machine can be improved.

Description

Trash rake rotation supplementary gate

Technical field

The utility model belongs to the equipment technical field of removing contamination, and says so a kind of more specifically and the matching used trash rake rotation of river course trash rake supplementary gate.

Background technology

At present; Rotary type trash cleaning device is integrated in one trashrack and sewage disposal apparatus and has realized that moving water removes contamination, thereby is widely used in water projects such as drainage and irrigation station, pumping plant and power station, because the structural limitations of rotary type trash cleaning device; Trash rake lower end grizzly bar is reserved certain tooth harrow rotary space apart from ground sill; For preventing that dirt from getting into the water wheels unit, the fixed supplementary gate of tooth harrow rotary space operated by rotary motion of prior art, part dirt still can be crossed fixed supplementary gate and get into unit; Thereby the impeller to unit brings influence, even causes stopping accident.

Summary of the invention

In order to address the above problem; The utility model provides a kind of trash rake rotation supplementary gate; Trash rake rotation supplementary gate is installed on the rotary type trash cleaning device bottom, and its concrete scheme is: described trash rake rotation supplementary gate is made up of trash rake side bar, track, trash rake grizzly bar, trash rake crossbeam, trash rake tooth harrow, bearing support, supplementary gate axle, limited block, auxiliary grizzly bar, it is characterized in that bearing support is fixedly connected on the bottom of trash rake side bar and gives prominence to grid body the place ahead; The supplementary gate axle is installed on the bearing support through the bearing at its two ends; Supplementary gate axially go up to be fixedly connected auxiliary grizzly bar, and auxiliary grizzly bar is alternate with the trash rake tooth harrow opens, on the trash rake tooth harrow setting circumversion chain in orbit; Track is fixed on trash rake side bar and the trash rake crossbeam; The top of auxiliary grizzly bar relies on deadweight to tilt to take and comes on the trash rake grizzly bar, and auxiliary grizzly bar can rotate freely along the supplementary gate axle, and limited block is set on the bearing support.

The beneficial effect of the utility model is the rotary space that trash rake rotation supplementary gate has been eliminated the trash rake tooth harrow, has avoided bigger dirt entering work unit, has improved the property safe and reliable to operation of rotary type trash cleaning device.

Description of drawings

Fig. 1 is the structural representation of the utility model; In the accompanying drawing:

1. trash rake side bar, 2. track, 3. trash rake grizzly bar, 4. trash rake crossbeam, 5. trash rake tooth harrow, 6. bearing support, 7. supplementary gate axle, 8. limited block, 9. auxiliary grizzly bar.

The specific embodiment

In conjunction with accompanying drawing the utility model is described in further detail; So that the public grasps the implementation method of the utility model better; The concrete embodiment of the utility model is: described trash rake rotation supplementary gate is made up of trash rake side bar 1, track 2, trash rake grizzly bar 3, trash rake crossbeam 4, trash rake tooth harrow 5, bearing support 6, supplementary gate axle 7, limited block 8, auxiliary grizzly bar 9; It is characterized in that bearing support 6 is fixedly connected on the bottom of trash rake side bar 1 and outstanding to grid body the place ahead, supplementary gate axle 7 is installed on the bearing support 6 through the bearing at its two ends, and supplementary gate axle 7 upwards is fixedly connected auxiliary grizzly bar 9; Auxiliary grizzly bar 9 and trash rake tooth harrow 5 alternate opening; Trash rake tooth harrow 5 is arranged on the circumversion chain in the track 2, and track 2 is fixed on trash rake side bar 1 and the trash rake crossbeam 4, and the top of auxiliary grizzly bar 9 relies on deadweight to tilt to take and comes on the trash rake grizzly bar 3; Auxiliary grizzly bar 9 can rotate freely along supplementary gate axle 7, and limited block 8 is set on the bearing support 6.

The beneficial effect of the utility model is the rotary space that trash rake rotation supplementary gate has been eliminated trash rake tooth harrow 5, has avoided bigger dirt entering work unit, has improved the property safe and reliable to operation of rotary type trash cleaning device.
