Abstract

The utility model discloses a middle trough coal accumulation prevention structure of a bottom sealing type scraper conveyor and belongs to the technical field of bottom sealing type scraper conveyors. The front end of a bottom sealing plate (4) is provided with a notch on the basis of an original structure, a clearing plough (2) is installed at the position of a scraping plate ledge (1) corresponding to the notch of the bottom sealing plate (4), and a baffle ledge (5) is provided with a notch located at the position corresponding to the notch of the bottom sealing plate (4). By improvement, in the moving process of a middle trough from a gob to a coal wall, a small groove is pushed out on the ground at the notch position of the bottom sealing plate (4) through the clearing plough (2), raw coal taken into a lower cavity of the middle trough through a turnround chain falls into the groove through the position of the notch of the bottom sealing plate (4) and enters the gob through the corresponding notch of the baffle ledge (5) along with next movement, coal cannot be accumulated on the middle trough bottle sealing plate, so that power consumption and the potential safety hazard which are caused by the coal accumulation of the lower cavity of the middle trough are avoided, and the middle trough coal accumulation prevention structure guarantees that a device can run normally.

Description

The anti-long-pending texture of coal of sealing bottom type scraper conveyor middle groove

Technical field

The utility model relates to a kind of anti-long-pending texture of coal, and specifically the anti-long-pending texture of coal of a kind of sealing bottom type scraper conveyor middle groove, belongs to sealing bottom type scrapper conveyor technical field.

Background technology

Sealing bottom type scrapper conveyor, a kind of in the rectangular cross section housing of sealing, by means of moving flight chain, carry the continuous transport equipment of bulk material, be widely used in metallurgy, building materials, electric power, chemical industry, cement, harbour, harbour, coal, mine, grain and oil, food, feed, etc. industry and department.

At present, in coal mining process, sealing bottom type slat conveyer is turned one's head chain and a small amount of raw coal can be taken to intermediate channel, and what have amasss on intermediate channel bottom sealing plate, and alluvial forms and hardens, plate lower surface during the scraper plate that deposits when more not only can wear and tear, and consume a large amount of power; Serious meeting causes lower chain holding chain rupture, disconnected scraper plate, and the distortion of intermediate channel pucking etc., not only equipment is damaged, also cause certain potential safety hazard.

Summary of the invention

For the problems referred to above, the utility model provides a kind of sealing bottom type scraper conveyor middle groove anti-long-pending texture of coal, can clear up in time long-pending coal, avoids the potential safety hazard that produces because amassing coal, guarantees the normal operation of equipment.

For achieving the above object, the utility model comprises shovel board ledge, middle plate, bottom sealing plate and baffle, middle plate is corresponding up and down with bottom sealing plate, between form intermediate channel, shovel board ledge and baffle are separately positioned on bottom sealing plate both sides, on the basis of said structure, at bottom sealing plate front end, have breach, gap width 3-4cm, shovel board ledge is provided with a cleaning plough at bottom sealing plate breach correspondence position, the long 2-3mm of cleaning plough Length Ratio bottom sealing plate gap width, for outputing, release a minor groove when amassing coal, baffle has breach at bottom sealing plate breach correspondence position, form coal dropping port.

Bottom sealing plate front end vertical surface is skewed, and angle of inclination is 45-60 °.

Cleaning plough tilts to install, with vertical surface angle be 60-80 °.

Cleaning plough is movably arranged in shovel board ledge.

Compared with prior art, in the utility model, at bottom sealing plate front end, have breach, and increased a cleaning plough in the position of shovel board ledge correspondence breach, position at the corresponding breach of baffle also has breach, form coal dropping port, when intermediate channel by goaf in rib passing process, on ground, at the cleaned plough of bottom sealing plate gap position, release a minor groove, the raw coal of being brought into intermediate channel cavity of resorption by chain later falls into groove through bottom sealing plate indentation, there, with pass through the corresponding breach of baffle next time, enter goaf, thereby can on intermediate channel bottom sealing plate, not form long-pending coal, the consumption of power and the potential safety hazard that because of the long-pending coal of intermediate channel cavity of resorption, produce have been avoided, guaranteed the normal operation of equipment.

Accompanying drawing explanation

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

In figure: 1, shovel board ledge, 2, cleaning plough, 3, middle plate, 4, bottom sealing plate, 5, baffle.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in Figure 1, the anti-long-pending texture of coal of a kind of sealing bottom type scraper conveyor middle groove, comprise shovel board ledge 1, middle plate 3, bottom sealing plate 4 and baffle 5, middle plate 3 is corresponding Shang Xia 4 with bottom sealing plate, between form intermediate channel, shovel board ledge 1 and baffle 5 are separately positioned on bottom sealing plate 4 both sides, on the basis of said structure, bottom sealing plate 4 front ends have breach, gap width 3-4 cm, shovel board ledge 1 is provided with a cleaning plough 2 at bottom sealing plate 4 breach correspondence positions, with the long 2-3mm of cleaning plough 2 Length Ratio bottom sealing plate 4 gap width, for outputing, release a minor groove when amassing coal, baffle 5 has breach at bottom sealing plate 4 breach correspondence positions, form coal dropping port.

As the utility model, further improve, bottom sealing plate 4 front end vertical surface are skewed, and angle of inclination is 45-60 °, further guarantee can be slided in groove by the raw coal that later chain brings.

As the utility model, further improve, cleaning plough 2 tilts to install, with vertical surface angle be 60-80 °, can increase the area of releasing groove.

As the utility model, further improve, cleaning plough 2 is movably arranged in shovel board ledge 1, is convenient to maintenance and replacing time, guarantees work efficiency.

In the course of the work, intermediate channel by goaf in rib passing process, on ground, at the cleaned plough 2 of bottom sealing plate 4 gap position, release a minor groove, the raw coal of being brought into intermediate channel by chain later drops in groove through bottom sealing plate 4 indentation, there, with pass through the corresponding breach of baffle 5 next time, enters goaf.

In sum, compared with prior art, in the utility model, at bottom sealing plate 4 front ends, have breach, and in the position of shovel board ledge 1 corresponding breach, increased a cleaning plough 2, position at baffle 6 corresponding breach also has breach, form coal dropping port, when intermediate channel by goaf in rib passing process, on ground, at the cleaned plough 2 of bottom sealing plate 4 gap position, release a minor groove, the raw coal of being brought into intermediate channel cavity of resorption by chain later falls into groove through bottom sealing plate 4 indentation, there, with pass through the corresponding breach of baffle 5 next time, enter goaf, thereby can on intermediate channel bottom sealing plate 4, not form long-pending coal, the consumption of power and the potential safety hazard that because of the long-pending coal of intermediate channel cavity of resorption, produce have been avoided, guaranteed the normal operation of equipment.
