Description

Drag conveyor

Technical field

The utility model relates to coal mining equipment, relates in particular to drag conveyor.

Background technology

China is thin widely distributed with ultra-thin coal seam, and reserves are abundant.At present, verify the girdle recoverable reserves and be about 61.5 hundred million tons, accounted for 20% of total recoverable reserves.According to statistics, national state-owned emphasis girdle reserves are 25.29 hundred million tons.Because lack the exploitation equipment that compliance is good, production efficiency is high, the thin seam mining per unit area yield is low, cost of production is high, deficiency in economic performance, makes a lot of coal enterprise abandon thin seam mining, causes the serious waste of coal resources.Be accompanied by continuing to increase of present exploitation dynamics, reserves thick and medium-thickness seam reduce day by day, and thin and ultra-thin coal seam will become main mining coal seam.Therefore, solve girdle high-efficiency mining problem for prolonging mine service-life, improve resource recovery, develop a circular economy, needing badly.Be subjected to the work plane spatial constraints, girdle exists the coal seam to bury deeply, the geological conditions complexity, and tomography is many, and the ore deposit is pressed big, and unit yield is low, and tunnel consumption rate height is taken over anxiety, problems such as workman's operating condition difference, thin seam mining is the weak link of coal pit mining always; Exploitation colliery drag conveyor commonly used is passed frame, tail passing frame, sprocket wheel, scraper plate, scraper chain, head lead-over groove, tail lead-over groove comprising head power set, tail power set, a plurality of chute, rack rails, scraper plate, head, and the head power set are provided with reducer, connect cover and motor; Chute is passed frame comprising the chute on left ledge, right ledge, chute base plate, right ledge right side; A plurality of chutes are that front and back distribute; Ledge upper surface, a left side is the coal-winning machine track; The head power set are fixedlyed connected with the chute front portion, and this kind drag conveyor only is suitable for the exploitation of thick and medium-thickness seam; In underground work, chute needs regular moving, in this course, the bolt that connects between chute and the chute is loosening easily, must in time tighten, and be engaged in its working strength of this work and danger in the down-hole all very big, also caused descend the application life of chute thus; Because the head power set fixedly connected with the chute front portion, the chute front portion can only be placed in the work plane, during the coal-winning machine operation one of the chute front portion section coal seam digging less than, the coal mining rate is low.

Summary of the invention

The purpose of this utility model provides a kind of drag conveyor thin and the ultra-thin coal seam exploitation that is suitable for.

For achieving the above object, the technical solution adopted in the utility model is: a kind of drag conveyor is comprising head power set, tail power set, a plurality of chute, and the head power set are provided with reducer, connect cover and motor; Chute is passed frame comprising the chute on left ledge, right ledge, chute base plate, right ledge right side; A plurality of chutes are that front and back distribute; Its characteristics are: be extended with the coal-winning machine track at the bottom of the left ledge left, the coal-winning machine track is with corresponding at the bottom of the left ledge and be an integral body; Coal-winning machine track left bottom has a boss that extends downwards; The chute on right ledge right side is passed on the frame and is had the cable channel that opening makes progress, and is fixedly connected with the cable hook on the right flank of cable channel right side wall, and chute passing frame is fixedlyed connected with cable channel.

Owing to be extended with the coal-winning machine track left at the bottom of the left ledge in the utility model, the coal-winning machine track is with corresponding at the bottom of the left ledge, and the coal-winning machine track is corresponding with mobile wheel in the coal-winning machine; So just reduced the working depth that coal-winning machine is mined, so the utility model is suitable for and the ultra-thin coal seam exploitation thin; Owing to have cable channel in the right ledge in the utility model, have the cable hook on the cable channel, portability cable on cable channel and the cable hook, safety when using the utility model.

The specific embodiment

Further specify embodiment of the present utility model and effect with following non-limiting embodiment.

Embodiment 1:

A kind of drag conveyor, as shown in Figure 1, 2, 3, pass frame 6, tail commonly used comprising head power set 1, tail power set 5 commonly used, head commonly used and pass frame, tail lead-over groove commonly used, a plurality of chute 3, cable channel 9, dumbbell pin 10, rack rails, sprocket wheel, scraper plate, scraper chain commonly used, the head power set are provided with reducer, connect cover and motor; The head power set are fixedlyed connected with common method with sprocket wheel; Scraper chain is installed on the sprocket wheel with common method and becomes to be in transmission connection with it; Scraper plate is installed on the scraper chain with common method; The head power set are fixedlyed connected with common method with head passing frame; It is corresponding with the hydraulic stem of passing jack in the hydraulic shield support that head is passed frame; Tail power set 5 are fixedlyed connected with common method with tail passing frame; It is corresponding with the hydraulic stem of passing jack in the hydraulic shield support that tail is passed frame; Chute is passed frame comprising the chute on left ledge 4, right ledge 8, chute base plate 7, right ledge 8 right sides; A plurality of chutes 3 distribute for front and back; Scraper plate, scraper chain are installed in the chute with common method respectively; A left side is extended with coal-winning machine track 2 left at the bottom of the ledge, and coal-winning machine track 2 is corresponding with 4 ends of left ledge and be an integral body; Coal-winning machine track 2 left bottom have a boss 11 that extends downwards; Coal-winning machine track 2 is corresponding with mobile wheel in the coal-winning machine; The chute on right ledge 8 right sides is passed on the frame and is had the cable channel 9 that is used to carry cable that opening makes progress, the fixedly connected cable hook 12 that carries cable that is useful on the right flank of cable channel 9 right side walls, and chute passing frame 6 is fixedlyed connected with cable channel 9; It is corresponding with the hydraulic stem of passing jack in the hydraulic shield support that chute is passed frame; Head power set 1 are connected with common method with the head lead-over groove; Tail power set 5 are connected with common method with the tail lead-over groove; A plurality of chutes 3 front and back are connected with common method with head lead-over groove, tail lead-over groove respectively; The right ledge of chute is fixedlyed connected with common method with rack rails; Rack rails is fixedlyed connected with common method with chute passing frame; In the present embodiment, reducer is a planetary reduction gear; The planetary reduction gear compact conformation, it is little to take up room; The head power set become to be arranged vertically with chute, and promptly head power set 1 are arranged in parallel about being; When the utility model was used in underground work, head power set 1 were installed in the haulage drift, and coal-winning machine can be adopted the coal seam in the sky work plane fully, coal mining rate height; In the present embodiment, chute connects by dumbbell pin 10 usefulness common methods before and after in the chute, ledge 4 left surfaces middle part, a chute left side is connected by dumbbell pin 10 usefulness common methods with ledge left surface middle part, a chute left side, back before each, and the right groove 8 of chute helps the right flank middle part to be connected by dumbbell pin 10 usefulness common methods with right ledge 8 right flanks of back chute middle part before each.
