Abstract
A kind of fully-mechanized mining working surface conveyer is anti-retracts device for coal, is made up of support unit and group coal unit.Two fasteners are threaded connection on stull axle, and by rotating two ends fastener, stull axle is tightly supportted in the middle of handpiece of scraper conveyer, and wherein fastener front end adds spring chair and pad, rear end dress check washer.Dial coal unit to be made up of wedge shape shifting block, wear-resistant nested, coal moving plate, bolt, resilient sleeve, connecting pin and spring cotter, coal moving plate is connected with wedge shape shifting block by bolt, and the embedding of wedge shape shifting block is wear-resistant is nestedly connected to form revolute pair with stull axle.During work, the scraper conveyor scraper intermittence mill pressure wedge shape shifting block of running drives coal moving plate intermittence to swing, thus is pushed aside by the float coal be deposited under slat conveyer, avoids slat conveyer to be drawn in kerve by float coal.Whether whether resilient sleeve can collide selection according to coal moving plate and slat conveyer bottom land is installed; Wearing course can plate in wedge shape shifting block mill pressure place; Establish auxiliary hole to facilitate lifting in the middle of on the downside of coal moving plate.
Description
Technical field
The utility model is applicable to the cleaning of the slat conveyer head bottom float coal of fully-mechanized coalface.
Background technology
Fully-mechanized mining working surface conveyer is altered or other reason causes slat conveyer and transportation roadway loader to overlap unreasonable time, slat conveyer head bottom accumulates that float coal is many, and scraper plate is easily drawn in chute, causes load large, damages mechanical equipment.At present, production unit is mainly taked to raise head, labor cleaning, rush the ways such as chute with water, but still there are some problems: the head amount of raising is limited, when running can not labor cleaning bottom float coal, water rushes chute not only wastes water source but also affect ature of coal.
Summary of the invention
In order to control to adopt face slat conveyer grease head highness, save source ensuring ature of coal, reduce labour intensity, the deficiency of float coal can not be cleared up when overcoming operation, the utility model provides a kind of fully-mechanized mining working surface conveyer to prevent retracting device for coal, low, the easy installing/dismounting of this installation cost, Automatic clearance float coal, applicable Multiple Type slat conveyer.
The utility model solves the technical scheme that its technical matters adopts: the anti-device for coal that retracts of fully-mechanized mining working surface conveyer is primarily of fastener, check washer, wedge shape shifting block, wear-resistant nested, stull axle, bolt, pad, spring chair, resilient sleeve, connecting pin, spring cotter and coal moving plate composition.Support section is made up of stull axle, fastener, check washer, pad, spring chair, it is characterized in that two ends fastener is threaded connection at stull axle two ends, stull axle two ends are processed with for spacing step, fastener front end has and the boss adopted face slat conveyer head underpunch and match, fastener rear end and stull axle all establish the groove for installing check washer, stull axle and fastener are all processed with six sides being convenient to spanner dismounting, by turning two ends fastener, holddown spring pad, tightly supports stull in nose sprocket wheel of scraper conveyor bottom.Dial coal part to be made up of wedge shape shifting block, wear-resistant nested, tie bolt, resilient sleeve, connecting pin, spring cotter and coal moving plate, wedge shape shifting block embeds wear-resistant abaculus and stull axle forms revolute pair, be welded to connect plate in wedge shape shifting block lower end and hole, make it to carry out bolt with coal moving plate to be connected, reinforced rib is established in wedge shape shifting block both sides; If coal moving plate and slat conveyer bottom land collide, then below coal moving plate, resilient sleeve is installed in both sides, connects and fix with spring cotter with connecting pin, establishes auxiliary hole so that uses such as liftings in the middle of coal moving plate.During work, along with the running of Scraper Conveyor in Mining Face, scraper plate intermittent mill pressure wedge shape shifting block, drives coal moving plate to do intermittent swing, thus pushes the float coal being deposited in slat conveyer head bottom aside, avoid conveyer to be drawn in kerve by float coal.Wearing course can plate in wedge shape shifting block mill pressure place.
Benefit of the present utility model is, in fully-mechanized mining working surface conveyer runs, coal moving plate intermittence swings clears up head bottom float coal, reduce labour intensity, and structure is simple, easy to disassemble and assemble, prevents float coal from drawing in kerve increase load and causes the Electromechanical Accidents such as chain rupture.

In FIG: 1. fastener, 2. check washer, 3. wedge shape shifting block, 4. wear-resistant nested 5. stull axle, 6. bolt, 7. pad, 8. spring chair, 9. resilient sleeve, 10. connecting pins, 11. spring cotters, 12. coal moving plates.
Detailed description of the invention
Fully-mechanized mining working surface conveyer is in FIG anti-retracts device for coal by fastener (1), check washer (2), wedge shape shifting block (3), wear-resistant nested (4), stull axle (5), bolt (6), pad (7), spring chair (8), resilient sleeve (9), connecting pin (10), spring cotter (11), the part such as coal moving plate (12) composition.First stull axle (5) both sides are installed to after two wear-resistant nested (4) being embedded wedge shape shifting block (3) respectively, and by shaft shoulder location, then install check washer (2) and fastener (1) composition support unit respectively at stull axle (5) two ends, its Intermediate gasket (7) and spring chair (8) are arranged on the boss of fastener (1) front end respectively.Coal moving plate (12) to be connected with wedge shape shifting block (3) by bolt (6) and stull axle (5) forms revolute pair, wherein connecting pin (10) connects resilient sleeve (9) and coal moving plate (12), spring cotter (11) is inserted connecting pin (10) head perforation internal fixtion.
Principle of work of the present utility model: as shown in Figure 1, aim at the hole under fully-mechanized mining working surface conveyer machine head chain wheel, turn two fasteners (1) respectively, holddown spring pad (8) also uses check washer (2) locking, stull axle (5) is made tightly to support in conveyer head bottom, when slat conveyer runs, intermittent mill pressure wedge shape shifting block (3) of scraper plate, drive coal moving plate (12) to do intermittent swing, thus push the float coal of conveyer head bottom aside.Resilient sleeve (9) can prevent from colliding at the bottom of coal moving plate (12) and conveyor pan.
