Abstract
The utility model discloses a flow guide device of a coal feeder, and a coal feeder, wherein the flow guide device comprises a hopper and a vibrating screen, wherein the opening at the upper end of the hopper is communicated with the coal outlet at the bottom of a coal storage bunker, the vibrating screen is connected to the lower part of the hopper and is provided with an inclined plane, and polyvinyl wear-resisting plates are fixedly arranged on both the inner wall of the hopper and the inclined plane of the vibrating screen. According to the flow guide device of the coal feeder and the coal feeder, provided by the utility model, by arranging the polyvinyl wear-resisting plates on the inner wall of the hopper and the inclined plane of the vibrating screen, the friction force of the downward running of raw coal can be reduced, raw coal blockage can be prevented, and the production efficiency is improved.
Description
Technical field
The utility model relates to the feeder structure technology, relates in particular to a kind of feeder guiding device and feeder.
Background technology
Feeder is mainly born the task of raw coal temporary in coal store being sent to continuous, even, adjustablely the next stage travelling apron as the major equipment of coal production system.Feeder mainly comprises hopper and vibrating grizzly, hopper is accepted the raw coal that flows out from the opening of coal store below, vibrating grizzly is connected to the below of hopper, vibrating grizzly is with the dip plane, under the driving of vibration motor, raw coal falls along the dip plane of vibrating grizzly, carries out follow-up transportation to flow into next stage equipment.
But, the ature of coal degree of sticking together in existing mining area is larger, aqueous ingredients is higher simultaneously, raw coal easily form on the feeder vibrating grizzly stick together, harden and cryogenic conditions under freeze sticking, often cause the sticking coal of feeder vibrating grizzly even to stop up, have a strong impact on the feeder instant flow rate and control, the situation that raw coal stops up even can occur, affect production efficiency.
The utility model content
The utility model provides a kind of feeder guiding device and feeder, to solve defective of the prior art, prevents that raw coal from sticking together, stopping up, and enhances productivity.
The utility model provides a kind of feeder guiding device, comprise hopper and vibrating grizzly, the upper end open of described hopper communicates with the coal outlet of coal store bottom, described vibrating grizzly is connected to the below of described hopper, and described vibrating grizzly has the dip plane, wherein: all be fixedly installed the polyethylene wearproof plate on the inwall of described hopper and the dip plane of described vibrating grizzly.
Feeder guiding device as above wherein, preferably, also comprises: flashboard, described flashboard are arranged between described hopper and described vibrating grizzly.
Feeder guiding device as above, wherein, preferably: described polyethylene wearproof plate is square plate.
Feeder guiding device as above, wherein, preferably: the length of described polyethylene wearproof plate is 1.5 meters, and width is 1.5 meters, and thickness is 0.04 meter.
Feeder guiding device as above, wherein, preferably: described polyethylene wearproof plate is bolted to connection on the dip plane of the inwall of described hopper and described vibrating grizzly.
Feeder guiding device as above, wherein, preferably: described hopper is funnel-form.
The utility model also provides a kind of feeder, wherein: comprise the feeder guiding device that the utility model provides.
The feeder guiding device that the utility model provides and feeder have reduced by the polyethylene wearproof plate is set the friction force that raw coal flows downward on the dip plane of hopper inwall and vibrating grizzly, prevented the obstruction of raw coal, have improved production efficiency.
Description of drawings
The feeder guiding device structural representation that Fig. 1 provides for the utility model embodiment.
The specific embodiment
The feeder guiding device structural representation that Fig. 1 provides for the utility model embodiment, as shown in Figure 1, this guiding device comprises hopper 1 and vibrating grizzly 2, wherein, the coal outlet of the upper end open of hopper 1 and coal store bottom 3 communicates, vibrating grizzly 2 is connected to the below of hopper 1, and vibrating grizzly 2 has the dip plane.Raw coal 4 falls from coal outlet and enters into hopper 1, then slides along the dip plane of vibrating grizzly 2, drops in next stage equipment and transports.The shape of hopper 1 can be for multiple, as long as can guide raw coal 4 to fall.Preferably, hopper 1 is set is funnel-form, more be conducive to flowing downward of raw coal 4.All be fixedly installed polyethylene wearproof plate 5 on the dip plane of the inwall of hopper 1 and vibrating grizzly 2.Polyethylene wearproof plate 5 has extremely low friction coefficient, and the characteristics of its high smooth degree are conducive to the downslide of raw coal 4, prevents that raw coal 4 from stopping up, and improved production efficiency.The simultaneously application of polyethylene wearproof plate 5 has reduced the damage that thermal friction brings, and has reduced the loss of hopper 1 inwall and vibrating grizzly 2 dip plane.
Preferably, polyethylene wearproof plate 5 is square plate, and length is 1.5 meters, and width is 1.5 meters, and thickness is 0.04 meter.Size according to hopper 1 inwall and vibrating grizzly 2 dip plane, can choice for use polylith polyethylene wearproof plate 5, make a call to uniformly six holes on every block of plate, simultaneously also beat respectively six corresponding holes at hopper 1 inwall and vibrating grizzly 2 dip plane, correspondence wears bolt again, realize polyethylene wearproof plate 5 respectively with being connected of hopper 1 and vibrating grizzly 2.
On the basis of above-described embodiment, this guiding device also is provided with flashboard 6, is arranged between hopper 1 and vibrating grizzly 2.When flashboard 6 was opened, raw coal 4 fell, and falls on vibrating grizzly 2 from hopper 1.When flashboard 6 is closed, stop that raw coal 4 falls, can carry out the transportation of subordinate equipment this moment.
The utility model embodiment also provides a kind of feeder, the feeder guiding device that provides comprising the utility model any embodiment.
The feeder guiding device that the utility model embodiment provides and feeder have reduced by the polyethylene wearproof plate is set the friction force that raw coal flows downward on the dip plane of hopper inwall and vibrating grizzly, prevented the obstruction of raw coal, have improved production efficiency.
It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment technical scheme of the utility model.
