Abstract

The utility model discloses a reeling coal hopper dredging machine, solving the coal blockage problem and the coal bloating problem when a coal breakage bucket in a power-making system of a boiler is in service. The bucket wall of the coal breakage bucket is additionally provided with a motor, a decelerator, a balance, and a workpiece rod which is connected with and arranged in the coal bucket by a taper pin and a joint bearing. The middle part of the workpiece rod is provided with a U-shaped bracket which is fixed to the steel wall of the coal bucket, and a control box and a signal source are provided out of the workpiece rod. The utility model can ensure the timeliness and consistency of feeding coal, considerably saving labor and improving the working efficiency of devices.

Description

Reeling coal breakage bucket dredging machine

Affiliated field

The utility model is a kind of mechanical dredger.

Background technology

Powder manufacturing apparatus in the pulverized-coal fired boiler of thermal power plant is the key of boiler combustion, and coal supply whether normal directly influences exerting oneself of pulverized coal preparation system and boiler smooth combustion.So be in operation, coal is vital under the normal capacity of coal breakage bucket.Coal in the coal breakage bucket falls by the coal dropping port of gravity from the coal breakage bucket, and coal inferior is big because of ash, and viscosity is big, particularly in rainy season, often make the coal in the coal bunker stifled, and can not guarantee that coal supply or coal-supplying amount are not enough, influence exerting oneself of pulverized coal preparation system at the upper compressive canopy of feeder.When emerged in operation chute blockage, canopy coal phenomenon, to be manpower impact the outer wall of coal breakage bucket with iron hammer to common way, forces down coal by vibrations.Do not only labor intensive like this, breaking-up equipment, and the mediation effect is extremely slow when running into the stifled phenomenon of continuous canopy, can not reach the production needs far away.

Summary of the invention

For the canopy that overcomes the coal breakage bucket, not block up coal and coal-supplying amount not enough and influence the problem that pulverized coal preparation system is exerted oneself, and guarantees the steady operation of system, the utility model provides a kind of dredging machine.Can not only effectively in time dredge canopy, chute blockage, and save manpower greatly, improve the operating efficiency of equipment.

The technical scheme that its technical problem that solves the utility model adopts is: install motor, reductor and escapement additional on coal breakage bucket headwall, be connected the workpiece bar of inserting in the coal bunker with oscillating bearing by taper pin, workpiece bar medium position has U type support casing card, and U type support is fixed on the coal bunker steel wall.Peripheral control box and signal source.When canopy, stifled phenomenon appear in the coal in the coal breakage bucket, disconnected coal signal can send work order, make the motor switch closure, the motor drives reductor rotates, reductor drives the escapement rotation, escapement drives the workpiece bar by its wobbler action power and makes the upper and lower, left and right moving, thereby reaches the mediation purpose, guarantees the normal coal supply of coal breakage bucket.

The beneficial effects of the utility model are: the promptness and the continuity that can ensure coal supply.

Description of drawings

Below in conjunction with accompanying drawing and example utility model is further described.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the vertical section structural map of embodiment of the present utility model.

In the accompanying drawing, 1. motor, 2. reductor, 3. taper pin, 4. escapement, 5. oscillating bearing, 6. workpiece bar, 7.U type support, 8 control cabinets, 9. disconnected coal signal source, 10. coal bunker steel wall, 11. supporting seats.

The specific embodiment

In Fig. 1, motor (1), reductor (2) link to each other with escapement (4), and oscillating bearing (5) links to each other with escapement (4) with workpiece bar (6) welding and by taper pin (3).

In embodiment illustrated in fig. 2, supporting seat (11) is installed, motor (1) links to each other with control cabinet (8), disconnected coal signal source (9), and U type support (7) cover blocks workpiece bar (6), is fixed on the coal bunker steel wall (10) with screw.When chute blockage, canopy coal occurring, disconnected coal signal source (9) is sent instruction, closed motor (1) switch, motor (1) rotates, driving reductor (2) rotates, reductor (2) drives escapement (4) rotation, and workpiece bar (6) is made the upper and lower, left and right moving by oscillating bearing (5) under the wobbler action power of escapement (4), thereby reaches mediation chute blockage, canopy coal purpose.

Claims

1, a kind of reeling coal breakage bucket dredging machine, be included in the motor, reductor and the escapement that install additional on the coal breakage bucket headwall, it is characterized in that escapement (4) is connected the workpiece bar (6) of inserting in the coal bunker by taper pin (3) with oscillating bearing (5), workpiece bar (6) medium position has the U type support (7) that is fixed on the coal bunker headwall.
