Abstract

The invention relates to mining, in particular to the means of mechanization of cleaning operations during the deserted excavation of very thin flat seams. The goal is to increase the reliability of work. The stopper scraperostug includes scraperostug (CC) 1, work 2 and idle 3 branches of the traction organ, grip 4, attachment 5, pneumatic shell (PO) 6 and ring holder (QD) 7. At the pickup 4, attachment 5 is fixed with the possibility of displacement KO 7 is connected to CC 1 and is installed with the possibility of interaction with software 6. Between branches 2, 3 software 6 is located and fixed on stations 8, 9. Branch 2 moves CC 1, and branch 3 moves prefix 5. 7 moves along the surface of the PO 6, the air pressure inside which maintains the roof. The diameter of the QF 7 is less than the diameter of the PO 6, with the result that the PO 6 is compressed and moved to the bottom by a thickness of the coal removed. Layout of the rubble strip 12 is performed by the attachment 5. This embodiment eliminates the possibility of the impact of SS 1 with the attachment 5, provides a more uniform pressing of the SS 1 to the face, reduces coal loss, reduces its ash and expands the scope of application according to the roofing conditions. 3 il.

Description

The invention relates to mining, in particular to the means of mechanization of cleaning operations during the deserted excavation of very thin flat seams.

The aim of the invention is to increase the reliability of operation due to the elimination of collisions and jamming of the scraperostrig and the attachment during oncoming traffic and the possibility of its use in formations with unstable roof rocks.

FIG. 1 shows a filling scraperostrug, general view; in fig. 2 shows a section A-A in FIG. in fig. 3 - node I in figure 1.

A stopper scraperostug includes a scraperostug 1, a worker 2 and a single 3 branches of a traction organ. On the idle branch 3 is placed the grip 4 (the latch and the springs conventionally not shown). On the gripper 4, the attachment 5 is fixed with the possibility of displacement. Pneumatic sump 6 is connected to the scraper housing 1, ring 7 and attached to the bypass 8 and the driving 9 stations located respectively at the ventilation 10 and the transport 11.

Bookmark scraperostug works as follows.

The scraper edge 1 moves along the lava by the working branch 2 of the thrusting organ, and the attachment 5 moves idle by its branch 3. The ring casing 7 is pivotally connected to the body of the scraperostrag 1 and moves on the surface of the pneumatic membrane 6, the air pressure inside which maintains the roof.

Since the diameter of the annular casing 7 is smaller than the diameter of the pneumatic membrane 6, then at the location of the holder 7, the membrane 6 is compressed, detached from the roof and from the soil. As the coal is excavated, the scraperosteg 1 moves along the strike, as the bypass 8 and the driving station 9 move along the mine workings the direction of the notch, the clamp scraperostrug 1 to. Being kinematically connected-4 clip 7 with the pneumatic envelope 6, the scraperostrug 1 moves the pneumatic envelope 6 along the line 10

wipe the thickness of the removed chips. Attachment 5, connected to gripper 4, through which the idle branch of the 3 rd body passes, carries out the laying of the rubble 12. Placing the pneumatic membrane 6 between the working 2 and idle 3 branches of the traction body eliminates the possibility of the impact of the scraperostrig 1 with the prefix 5. At the same time at the same time, it is an additional row, the lining between the face and the rubble 12 and provides a more uniform pressing of the scraperoscle 1 to the face.
