Abstract

The utility model discloses a dump car system with a telescopic chute, which comprises a hopper and a traveling track, wherein the hopper is mounted on a car body. The dump car system is characterized in that the outlet of the hopper is connected with a telescopic chute; the telescopic chute comprises more than two chute sections which are in sleeve joint with each other in sequence; the sizes of the openings of the chute sections are increased in sequence from the top down; a clamping device is arranged on each chute section; one end of a wire rope is connected with a windlass arranged on the car body; the other end of the wire rope is connected with the lowest chute section of the telescopic chute and changes direction through a guide pulley; the telescopic chute can reduce the distance from the opening of the chute to the surface of a stockpile and flying dust produced during the dumping of the dump car. The dust suppression mode doesn't need water, compressed air and other energy sources, has no secondary pollution, is free of the problem that a sprinkling or spraying nozzle is blocked, and successfully solves the difficult problem that flying dust is produced during dumping in an open space, which can not be solved in air-extraction dust removal.

Description

A kind of dump car system with telescopic spouting

Technical field

The utility model relates to the delivery device that a kind of bulk material adhesive tape is carried, and relates in particular to a kind of dump car.

Background technology

In the prior art; The dump car that industry such as iron and steel, coal has a large amount of bulk materials need adopt adhesive tape to carry carries out discharging; Existing dump car system keystone configuration such as Fig. 1, shown in Figure 2 are made up of vehicle frame 1`, traveling gear 2`, device for transporting objects 3`, discharge funnel 4`, elephant trunk 5` and walking rails.The conventional confguration of vehicle frame 1 is an integral type, and traveling gear 2`, device for transporting objects 3`, discharge funnel 4` and elephant trunk 5` are installed on the vehicle frame 1`.

Often produce a large amount of dust during the dump car discharging, adopt following four kinds of mode dedustings at present usually: one, on each feed bin, establish dedust air duct, make negative pressure in the storehouse, the airborne dust of generation gets into dust exhaustor through dedust air duct; Two, establish an exhausting arm on the dump car, an end of arm moves with dump car, and the other end of arm inserts mobile ventilation slot and carries out dedusting; Three, dump car carries the ventilation and dust removal device, is discharged in the storehouse again after dust is caught; Four, the elephant trunk exit is provided with watering or atomising installation.

The first three dust collector is the structure more complicated not only, and energy consumption is high, and also has a common limiting condition, and that is exactly in a relative fully enclosed can cause the environment of negative pressure, to use, so generally when discharging in the storehouse, adopt.When in the stock ground during discharging, because space outerpace opens wide, this mode of ventilation and dust removal is inapplicable.The 4th kind of dedusting method not only can be wasted a large amount of water sources, and problems such as shower nozzle obstruction take place, and is not suitable for and runs into water the material that character changes just takes place.

The utility model content

The purpose of the utility model provides a kind of dump car system with telescopic spouting.

In order to realize this purpose; Adopt following technical scheme: a kind of dump car system with telescopic spouting; Comprise the funnel and the walking rails that are installed on the car body, it is characterized in that: the outlet of said funnel be connected with socket successively by the flexible chute formed of the above chute section of two joints, said chute end opening size from top to bottom increases successively; Each saves the chute section and is provided with gripping mechanism; Steel rope one end links to each other with winch on being arranged on car body, and the other end is connected with a joint chute section bottom of telescopic spouting, and alters course through the changed course pulley on the car body.

As further optimization, after elephant trunk increased Telescopic, its weight can corresponding increase.In order to make that dump car is not easy to tumble, the walking rails of said dump car system is arranged on the ground or storehouse face of travelling apron support both sides, to reduce the center-of-gravity position of dump car.

As further optimization, steadily flexible in order to guarantee telescopic spouting, said steel rope is two, is separately positioned on the both sides of telescopic spouting, is connected with winch through cooresponding changed course pulley changed course back.

As further optimization, confirm the flexible scope of flexible chute for ease, reduce airborne dust, also be provided with the level-sensing device that the stockpile surface height is detected on the said car body.

The beneficial effect of the utility model is: telescopic spouting can reduce the distance of elephant trunk mouth to the stockpile surface, the airborne dust that produces when reducing the dump car discharging.This kind dust suppression mode does not need water, pressurized air equal energy source, and non-secondary pollution does not exist watering or spray nozzle blockage problem yet.Produce the difficult problem of airborne dust when successfully having solved the open space discharging that ventilation and dust removal cann't be solved.On integral structure, the walking rails of dump car is located on the ground or storehouse face of travelling apron support both sides, and whole down-shift of working center has improved operation stability of equipment and reliability.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further description.

To shown in Figure 6, the car body 7 of dump car can be reciprocating on walking rails 6 like Fig. 3, and funnel 8 is installed on the dump car car body 7, and the inlet of telescopic spouting 2 is connected with the outlet of funnel 8.

Telescopic spouting 2 is made up of some joint chute sections, and each joint becomes greatly by order of connection opening size successively, and is wherein minimum with funnel 8 bonded assembly chute section opening sizes.For piston type connects, the joint of big opening can be enclosed within the outside than trifle between adjacent two chute sections, and each joint is provided with gripping mechanism, prevents that adjacent two joints break away from.Through the piston motion between each joint, telescopic spouting 2 can wholely elongate or whole the shortening.The walking rails of dump car system is arranged on the ground or storehouse face of travelling apron support 9 both sides.

Steel rope 3 one ends link to each other with winch 5, and the joint away from funnel 8 on the other end and the telescopic spouting 2 is connected, and steel rope 3 alters course through changed course pulley 4.Have the both sides that two steel ropes 3, two groups of changed

course pulleys

4 and 5, two steel ropes 3 of a winch are separately positioned on telescopic spouting, then be connected through cooresponding changed course pulley 4 changed courses respectively with winch 5.Two steel ropes 3 are strained simultaneously and loosened, and are steadily flexible to guarantee telescopic spouting 2.When steel rope 3 is in relaxed state, by gravity, telescopic spouting 2 is in maximum and stretches out state.Winch 5 can be made retraction movement through steel rope 3 and changed course pulley 4 pulling telescopic spoutings 2, and the length of withdrawal can confirm that the stockpile surface height detects through the level-sensing device that is arranged on the dump car according to the stockpile surface height.

The elephant trunk of the utility model can stretch as required, makes the elephant trunk mouth remain very little distance to the distance on stockpile surface, reduces airborne dust.This structure of the utility model is specially adapted to the discharge operation of input sealing-tape machine in the elongated sealing stock ground.
