Description

Two main two auxiliary novel two-side rotary discharger discharge arm

Technical Field

The utility model relates to a field is carried to bulk material such as thermoelectricity, iron and steel factory, chemical plant specifically is a two main two pairs of novel two side rotary discharger's the arm of unloading, is applicable to materials such as coal, coke, ore, lime stone, is applied to thermal power plant and iron and steel factory slot formula material ditch, the rotary discharger of unloading long distance or fixed point, perhaps among the large and medium-sized thermal power plant and iron and steel factory, the bulk cargo conveying system of chemical plant.

Background

The double-side rotary discharger is commonly used in a slit type material ditch of a thermal power plant and an iron and steel plant, and can travel along a longitudinal rail of the coal ditch or stop at one position to quantitatively, uniformly and continuously discharge materials such as coal and the like onto a coal conveying belt.

When the bilateral rotary discharger discharges materials, when the traditional two-arm blade claw discharges materials, conveying belts can be deviated due to discontinuity and discontinuity of conveyed materials, and discontinuous impact can be caused to lower-level conveying equipment, so that the damage of the lower-level conveying equipment is aggravated easily, and the maintenance cost is increased; although the traditional four-arm and six-arm leaf claw overcomes the discontinuity of materials, the four-arm and six-arm trippers always have partial discharge arms in the materials, and the quick shunting function cannot be completed.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to overcome current defect, provide the unloading arm of two pairs of novel two side rotatory trippers of two owners, can accomplish quick shunting and can guarantee the even continuous unloading arm of material again, can effectively solve the problem in the background art.

In order to achieve the above purpose, the utility model provides a following technical scheme: the two main blade claws and the two auxiliary blade claws are fixedly arranged on the blade claw fixing hub;

the main leaf claw and the auxiliary leaf claw are both arc-shaped in outline, the ends of the main leaf claw and the auxiliary leaf claw, which are contacted with the leaf claw fixing hub, are bolt flange holes, the main leaf claw and the auxiliary leaf claw are connected with the leaf claw fixing hub into a whole through bolts, the two auxiliary leaf claws and the two main leaf claws rotate in the same direction, the two auxiliary leaf claws and the two main leaf claws are parallel and level with the fixed positions of the leaf claw fixing hub, and the two auxiliary leaf claws are contained in the arc-shaped range of the two main leaf claws.

As an optimized technical scheme of the utility model, two main leaf claw and vice leaf claw are personally submitted 180 distributions in leaf claw fixed wheel hub's the outside.

As an optimal technical scheme of the utility model, the one end design that leaf claw fixed wheel hub was kept away from to main leaf claw and vice leaf claw is a closed angle, and its closed angle is used for breaking into the material.

As a preferred technical scheme of the utility model, main leaf claw and vice leaf claw constitute by arc mainboard, cowl and a plurality of deep floor, and wherein the tip of arc mainboard is the closed angle, and cowl is located the arc inboard of arc mainboard, and a plurality of deep floor slope sets up, and near setting up with cowl.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the main leaf claw and the auxiliary leaf claw are used for material shifting in a coordinated mode, the auxiliary leaf claw firstly shifts and sends the materials to the conveying belt, the main leaf claw immediately shifts and sends the materials to the conveying belt after the main leaf claw, continuity is achieved, the materials on the conveying belt are more uniform, discontinuous material flow cannot occur, discontinuous impact on subordinate conveying equipment is reduced, the service life of subordinate equipment is prolonged, and maintenance cost is reduced.

2. The main blade claw and the auxiliary blade claw are symmetrically arranged for material shifting at 180 degrees, and can be designed to be reset by the material shifting claw during shutdown, so that the main blade claw and the auxiliary blade claw are not in a coal shifting area when the main blade claw and the auxiliary blade claw are ensured to rapidly walk to a fixed point position and are stopped, and the rapid shunting function can be completely met relative to four-arm and six-arm dumpers.

3. The two main blade claws and the two auxiliary blade claws are used for simultaneously shifting materials, the two auxiliary blade claws play a role in loosening material stacking density, resistance of the two main blade claws during material shifting is reduced, the material shifting process is smooth, meanwhile, the arrangement mode reduces abrasion of the main blade claws, the service life is prolonged, and the maintenance cost is reduced.
