Abstract

The utility model discloses an ore delivery machine dust keeper of unloading, including the bellows, the upper end of bellows is fixed in the frame of ore delivery machine through last backup pad, and the lower extreme of bellows is connected with the bottom suspension fagging, is provided with the lug on the bottom suspension fagging, is connected with the hoist cable of being connected with electric motor rotor on the lug, upward still is provided with the leading wheel of guide hoist cable in the backup pad, be provided with the level sensor who detects the ore position on the bottom suspension fagging, still include the controller of being connected with level sensor and motor electricity. The utility model discloses ore delivery machine dust keeper of unloading passes through the bellows at the unloading in -process and keeps apart material and outside air, and reducible material exposes the time in the air, reduces the quantity that the powder was blown away, and reduction air dust that can be very big pollutes, and receive and release the bellows through level sensor and the automation of controller control motor, can avoid bellows lower extreme and material pile to contact the putty problem that causes.

Description

Ores lifting machine discharging dust keeper

Technical field

The utility model relates to a kind of load transfer device, particularly a kind of ores lifting machine.

Background technology

It is strong that band conveyor has traffic capacity, and fed distance is far away, and structure is simply easy to safeguard, can carry out the advantage such as Programmed control and automation mechanized operation easily, be widely used in ores lifting field.

In prior art, belt conveyer is primarily of two end points cylinders and the tight closed belt conveyor composition overlapped on it.The cylinder driving belt conveyor to rotate is called head roll (driving drum); Another is only that the cylinder changing conveyer belt direction is called bend pulley.Head roll is driven by retarder by electrical motor, and belt conveyor relies on the friction force between head roll and belt conveyor to drag.Head roll is generally all contained in throw-off end, with increasing traction, is conducive to dragging.Material is fed by feeding end, drops on the belt conveyor of rotation, relies on belt conveyor friction drive to be transported to throw-off end and draws off.

Ores lifting machine ore unloaded drop on ore yard time, because ore height of drop is large, the time that in discharge process, ore is exposed in air is long, and the powdered ingredients in ore is easily blown away, and causes serious dust pollution.

Utility model content

In view of this, the purpose of this utility model is to provide a kind of ores lifting machine discharging dust keeper, to solve the problem that conveyer easily causes dust pollution in discharge process.

The utility model ores lifting machine discharging dust keeper, comprise the bellows guiding falling material, the upper end of described bellows is fixed on by upper backup pad in the frame of ores lifting machine, the lower end of described bellows is connected with lower supporting plate, described frame is provided with motor, described lower supporting plate is provided with hanger, described hanger is connected with the hoist cable be connected with rotor, described upper backup pad is also provided with the track adjusting wheel guiding hoist cable;

Described lower supporting plate is provided with the level sensor detecting ore position;

Also comprise the controller be electrically connected with level sensor and motor.

Further, described lower supporting plate is also provided with spray head.

The beneficial effects of the utility model:

The utility model ores lifting machine discharging dust keeper, is isolated material and outside air by bellows in blanking process, can reduce material and expose the aerial time, reduce the quantity that powder is blown away, and reduction air-borne dust that can be very large pollutes; And control motor automatic deploying and retracting bellows by level sensor and controller, bellows lower end can be avoided with stockpile to contact the putty problem caused.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model ores lifting machine discharging dust keeper.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is further described.

As shown in the figure, the present embodiment ores lifting machine discharging dust keeper, comprise the bellows 1 guiding falling material, the upper end of described bellows is fixed in the frame 3 of ores lifting machine by upper backup pad 2, the lower end of described bellows is connected with lower supporting plate 4, described frame is provided with motor 5, described lower supporting plate is provided with hanger 6, described hanger is connected with the hoist cable 7 be connected with rotor, described upper backup pad is also provided with the track adjusting wheel 8 guiding hoist cable;

Described lower supporting plate is provided with the level sensor 9 detecting ore position;

Also comprise the controller be electrically connected with level sensor and motor.

The present embodiment ores lifting machine discharging dust keeper, is isolated material and outside air by bellows in blanking process, can reduce material and expose the aerial time, reduce the quantity that powder is blown away, and reduction air-borne dust that can be very large pollutes.And the distance of bellows lower end and stockpile is detected by level sensor, detection signal is sent into controller by level sensor, when level sensor detects that the distance of bellows lower end and material level exceeds setting value, controller just controls motor automatic deploying and retracting hoist cable makes the distance of bellows lower end and stockpile to setting value, thus the putty problem and bellows that bellows lower end can be avoided to contact with stockpile cause and stockpile are apart from the too high problem causing dust pollution.

As the improvement to the present embodiment, described lower supporting plate is also provided with spray head 10, in ore powder more and wind speed is larger time, by delivery system being connected with spray head 10, utilize spray head 10 dedusting of spraying water to prevent dust pollution.

What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
