Abstract
The utility model provides a plate scraping machine which comprises a machine box. A coal feeding inlet is formed in the top portion of the machine box, and coal discharging outlets are formed in the bottom portion of the machine box. Two chain wheels are arranged in the machine box. A chain is sleeved on the two chain wheels. A plurality of scrapping plates are arranged evenly on the chain in a spaced mode. A groove is formed in one face, facing towards the inner wall of the machine box, of each plate scraping plate. The scraping plates comprise up-move scraping plates and down-move scraping plates. A coal cleaning port is formed in the bottom portion of the machine box of one side in the heading direction of the up-move scraping plates. Due to the fact that the coal cleaning port is formed in the bottom portion of the machine box, when the up-move scraping plates move to the machine box on one side in the heading direction, redundant accumulated coal in the grooves drops, and is cleaned from the coal cleaning port of the bottom portion of the machine box. Accumulation of coal in the machine box is avoided. The accumulated coal in the machine box can be cleaned conveniently and timely without affecting production.

The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides in a kind of situation not affecting production, conveniently, in time clears up the scrapper conveyor of the long-pending coal of cabinet.
The technical solution of the utility model provides a kind of scrapper conveyor, comprise cabinet, described cabinet open top forms coal-in port, described cabinet bottom opening forms coal dropping port, be provided with two sprocket wheels in the described cabinet, be arranged with chain on two described sprocket wheels, even interval arranges a plurality of scraper plates on the described chain, described scraper plate offers groove towards the one side of described cabinet inwall, described scraper plate comprises up scraper plate and descending scraper plate, and the described cabinet bottom of working direction one side of described up scraper plate also offers Qing Meikou.
Preferably, described coal dropping port place is provided with the coal breakage gate.
Preferably, described coal breakage gate is writing board shape, and described coal breakage gate along continuous straight runs is opened or closed.
Preferably, described coal breakage gate is that electronic control is opened or closed.
Preferably, described coal breakage gate is fixed-time control.
Preferably, described coal dropping port connects a surge bunker, and described coal breakage gate is used for isolating described coal dropping port and described surge bunker.
After adopting technique scheme, has following beneficial effect: owing to offer coal dropping port in the cabinet bottom, when up scraper plate runs to the cabinet of working direction one side, long-pending coal unnecessary in the groove falls, remove from the coal dropping port of cabinet bottom, avoid long-pending coal in cabinet, to pile up, in the situation that does not affect production, conveniently, in time clear up the long-pending coal of cabinet.

The specific embodiment
Further specify the specific embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 2, scrapper conveyor comprises cabinet 1, and cabinet 1 open top forms coal-in port 11, and cabinet 1 bottom opening forms coal dropping port 12, be provided with two sprocket wheels 2 in the cabinet 1, the left side is flower wheel, and the right side is drive wheel, and two sprocket wheels 2 are provided with chain 3, even interval arranges a plurality of scraper plates 4 on the chain 3, a joint that each side connects chain 3 of each scraper plate 4, chain 3 is together in series a plurality of scraper plates 4, and scraper plate 4 offers groove 41 towards the one side of cabinet 1 inwall.Scraper plate 4 comprises up scraper plate 4a and descending scraper plate 4b, the scraper plate 4 of top operation is called up scraper plate 4a among Fig. 2, the scraper plate 4 of below operation is called descending scraper plate 4b, and cabinet 1 bottom of the working direction of up scraper plate 4a (being the direction of upper arrow indication among a Fig. 2) side also offers clearly coal mouth 13.
During the scrapper conveyor operation, coal cinder 6 at first enters into the inside of cabinet 1 from coal-in port 11, and two sprocket wheels 2 of cabinet 1 inside rotate in the same direction, drives chain 3, and a plurality of scraper plates 4 that the even interval on the chain 3 arranges are with chain 3 motions.The direction of arrow indication is the sense of motion of chain 3 and scraper plate 4 among Fig. 2, and along with chain 3 constantly rotates on two sprocket wheels 2, the coal cinder 6 that descending scraper plate 4b will fall into cabinet 1 is distributed to each coal dropping port 12.Owing to offer groove 41(as shown in Figure 3 on the scraper plate 4), scraper plate 4 below when moving, groove 41 contacts with coal cinder 6, has part coal cinder 6 and enters into groove 41.When scraper plate 4 turned to the top from the below after, coal cinder 6 still remained in the groove 41.When scraper plate 4 transferred the below gradually to from the top, when namely scraper plate 4 ran to the bottom of cabinet 1 upward arrow direction one side, the coal cinder 6 in the groove 41 fell from groove 41, entered into the clear coal mouth 13 of cabinet 1 bottom.Like this, avoid coal cinder 6 constantly to accumulate in the cabinet 1, caused the distortion of cabinet 1, affected the normal operation of scrapper conveyor, realized in the situation that does not affect production, conveniently, in time cleared up the purpose of the long-pending coal of cabinet.
In the present embodiment, clear coal mouth 13 places are provided with clearly coal gate 14.When scraper plate 4 transfers when below gradually to from the top, coal cinder 6 temporarily is deposited in clearly coal mouth 13 places, when long-pending coal is accumulated to when a certain amount of, opens clearly coal gate 14, makes to amass coal and fall, remove.
In the present embodiment, clear coal gate 14 is writing board shape, and clear coal gate 14 along continuous straight runs are opened or closed.
Preferably, clear coal gate 14 can also be other shapes, as long as can play the effect of the clear coal mouth 13 of opening and closing, all belongs to protection domain of the present utility model.
Preferably, clear coal gate 14 opens or cuts out for electronic control, handled easily, guarantees safe production.Certainly, also can control manually the opening and closing of clear coal gate 14.
Preferably, clear coal gate 14 opens or cuts out for regularly electronic control.Preset shut S1 and opening time S2 in the scrapper conveyor, after shut S1 meter is full, controls clear coal gate 14 and automatically open, will amass coal and remove; At this moment, the opening time, S2 began timing, after opening time S2 meter is full, controlled clear coal gate 14 autoshutdowns; Repeat above-mentioned steps.
In the present embodiment, clear coal mouth 13 connects a surge bunker 5, and clear coal gate 14 is used for isolating clear coal mouth 13 and surge bunker 5, and surge bunker 5 is used for the long-pending coal that buffering falls.
Above-described only is principle of the present utility model and preferred embodiment.Should be pointed out that for the person of ordinary skill of the art, on the basis of the utility model principle, can also make some other modification, also should be considered as protection domain of the present utility model.
