SU1625983A1 - Coal plough - Google Patents

Abstract

The invention relates to excavation machines, in particular, plows. The goal is to improve the loading capacity of the plow by creating a loading opening 1 for reducing the energy consumption of coal loading. The plow includes a housing, at one end of which the incisive preparations (RG) are placed. The nadconveyern plate is displaced to the end of the plow body opposite to the WP and is made with bevels. The bevels of the over conveyor plate are placed in the channel of the plow chain. The length of the over conveyor plate is 0.25-0.5 of the plow body length. When approaching the drive station of the plow installation, the plow reverses and starts moving in the opposite direction. Due to the fact that the speed of the plow must be somewhat lower than the speed of the scraper chain, the plow is moving, somewhat lagging behind the coal immersed in the conveyor belt, producing the milling and cleaning of the coal. 3 silt (/ С

Description

The invention relates to excavation machines for snow-mining of coal mining, in particular, plows having an over-conveyor plate, and is mainly used in plow mills for one-sided coal mining in clearing holes.

The aim of the invention is to improve the loading capacity of the plow by creating a loading opening and reducing energy-consuming.

Hz of fig. I is the plow, the view from the side of the knob of FIG. 2, the same, top view; in fig. 3rd - left view

The plow has a conveyor plate 1, which is connected to one end of the L-shaped body 2 located on the bottom hole with t o | about. t conveyor for example

Its welding is 0.25-0.5 of the length of the casing 2. The location of the above-conveyor plate 1 at one end of the casing 2 with its length equal to 0.25-0.5 of the length of the casing 2 forms a loading opening 3.

At the same end of the casing 2, a leading support element 4 is placed, on which 5 is installed, which determines the size of the load to be removed during the working stroke and the screws 7 are fixed to the knife 7. The ski 5 is made with retail thickness depending on the required size of the removable chips.

The other end of the body 2 is provided with cutting heads 8 and 9. The cutting head 9 is intended for the lower group of cutters and is connected to the cutting head 8 of parallelI

The plow is raised to a height that provides the excavation of the reservoir at full capacity or recess, leaving the minimum upper bundle of coal using cutting heads 13 and 14. The tool heads 8, 9, 13, and 14 are provided with cutters 15. The end of the same end of the body 2 is equipped with plowshare 16 and knives 17. The plowshare 16 has a ski 18 that overlaps the edges of the cutters 15 when idling and protects them from rubbing against the bottom.

The nip conveyor plate 1 is equipped with control-chain mechanisms 19 and 20 with guide lugs 21 and 22 and bevels 23 m 24, which are located in channel 25 of the guide strug-1y chain. Par position — about 23 and 24 on the nedkonpirinoy gota 1 from the side of the working space on the space and and the canap 25 of the plow chain guide helps to remove the coal and shty from channel 5

The housing 2 also has a groove 26 under the guide tube, located IKJ behind the striking side of the conveyor. The housing 2 is on the cutting heads loading surface 27 and the surface 28

The plow works as follows
