Abstract
The utility model provides a back-portion scraper conveyer coal-blocking plate for underground coal mine fully-mechanized top coal caving, and relates to the back-portion scraper conveyer coal-blocking plate for underground coal mine fully-mechanized top coal caving. The designing scheme is that one end of a horizontal fixed plate is integrally welded with a longitudinal coal-blocking plate with a certain slope, a plurality of supporting plates are integrally welded between the fixed plate and the coal-blocking plate, and two ends of the coal-blocking plate are respectively provided with one connecting hole. The back-portion scraper conveyer coal-blocking plate for underground coal mine fully-mechanized top coal caving has the advantages that the coal-blocking plate is arranged on a scraper conveyer which is placed on the back portion of a working face, labor intensity of workers is reduced first, the workers does not need to work inside a narrow and small space below a back tail beam, secure environment is greatly improved, labor intensity is greatly lowered; the fact that a specially-assigned person cleans float coal is of no need, after the coal-blocking plate is mounted, only three timbermen can clean up a small quantity of float coal, productive technology is improved, and after the coal-blocking plate is added, the fact that the specially-assigned person cleans the float coal for a long time is nearly avoided.
Description
Technical field
The present invention relates to mining rear portion drag conveyor spillplate under a kind of coal mine.
Background technology
Along with popularizing of modern Mine Integrated mechanical coal mining technique, mine is towards the high-yield and high-efficiency future development, the caving roof coal hydraulic support that uses at present, lay two drag conveyors before and after the support, but the rear portion scraping board type send machine not keep off the coal facility, in case the coal amount is excessive in the Sub-Level Caving process, will cause a large amount of coals to overflow outside the drag conveyor chute, bring very large labour intensity to remove to clear up float coal to the workman, key be in scale removal process the workman can the small space under the support tail boom in operation directly do not play waist, both dangerous, affect again whole process for stoping, the work plane coal is deposited on the base plate, can not in time transport, output is not high, can not be complementary with the fully mechanized mining high-yield and high-efficiency.
Summary of the invention
The technical problem to be solved in the present invention is: in production period Sub-Level Caving link, can prevent to greatest extent that a large amount of coal heaps from overflowing the rear portion drag conveyor.
Design scheme of the present utility model is: be welded with vertical spillplate of constant slope in an end one of horizontal fixed head, one is welded with the several piece gripper shoe between fixed head and spillplate, and a connecting hole is respectively arranged at the spillplate two ends.Angle between fixed head and spillplate is between 70～85 °.Gripper shoe is no less than 2.
Good effect of the present utility model is: this device is installed in work plane rear portion drag conveyor, has at first alleviated workman's labour intensity, the workman not be used in the interior work of small space of rear tail boom below, and security context greatly improves, and labour intensity reduces greatly; Need not to arrange the special messenger to clear up float coal, only need 3 timberers just a small amount of float coal can be cleaned out behind the spillplate and installed; Improve production technology, increased spillplate later on hardly with arranging the special messenger to clear up for a long time float coal.

Accompanying drawing 1 is the utility model Facad structure schematic diagram.
Accompanying drawing 2 is the left TV structure schematic diagram of the utility model.
Accompanying drawing 3 is the utility model installment state structural representation.
The specific embodiment
The utility model comprises: spillplate 2, fixed head 3, gripper shoe 4, connecting hole 5, its parts are all made of 8 ㎜ steel plates.Spillplate 2 is welded on the fixed head 3, between angle α be 80 ° of the bests.3 gripper shoes 4 are welded on spillplate 2 and the fixed head 3, thereby form the effect that spillplate is supported, by Fig. 3 illustrate fixed head 3 by 2 models be M20 * 80 be bolted on the drag conveyor 1, become an integral body thereby the bolt of connecting hole 5 by 1 M16 cooperates steel plate that 2 adjacent spillplates are coupled together with drag conveyor is capable.The length of considering a joint chute is 1250mm, the design spillplate is long to be 1245mm, design height is 300mm, base length and width specification is 1245 * 100mm, seamless welding gets up between base and the spillplate, angle is 80 °, beat the circular hole that diameter is 20mm in each 150mm position, distance base center line both sides, the screw that with diameter is 18mm is connected the jail with the rear portion drag conveyor, in order to increase it at the gear coal intensity of the production period triangular shaped steel plate of burn-oning in distance spillplate two 150mm and centre position respectively, at spillplate two apart from the side 20mm, the circular hole that to make a call to respectively a diameter apart from 50mm position, top be 18mm serves as and cooperates steel plate to couple together reinforcement rigidity between the spillplate.When Sub-Level Caving coal amount occurring when excessive, spillplate has played good effect, has thoroughly solved the drawback of float coal outflow, artificial clear coal, reduces to greatest extent economic loss and accident rate, ensures safety in production.
