Description
The invention relates to mining and can be used for extracting ore from strata
with complex deposition structures.
The claimed invention is directed to solving the problem of providing bulk and
selective ore extraction with one and the same machine.
Known in the art is a face-working machine comprising a housing and two
actuating elements disposed at the ends of the housing, the actuating elements being
in the form of arms rotatable in the vertical plane and provided with a built-in drive
and a cutting screw conveyor ("Glukauf", No.8, 1992, p.7).
The deficiency of this construction is a low efficiency of the machine when
working seams of a mineral interlayered with barren rock because it is impossible to
provide frontal control of the position of the cutting screw conveyors relative to the
beam of the face.
The most pertinent technical solution adopted as the prototype is a machine
(U.S.S.R. Patent 1553670) comprising a housing and two actuating elements hinged
thereon, the actuating elements being in the form of screw conveyors with drives for
extracting the mineral,
and a cutting drum having a vertical axis of rotation for extracting rocky
interstratification. The cutting drum with the drive is disposed on an additional
support frame hinged to the machine. When turning relative to the support frame.
the cutting drum occupies a position of being ahead of the screw conveyors in the
direction of the face, and gets positioned behind them in the course of work.
The deficiency of this construction is its complication due to the presence of a
third cutting member for extracting rocky interstratification, since for bulk
extraction the machine can be used without the presence of a cutting drum; this
lowers the effectiveness of utilization of the machine in various methods of working a
mineral, including such minerals that have complex deposition structures. Moreover
an additional cutting member increases the dimension of the machine lengthwise,
making it more difficult to carry out end operations at conjugations of rock with
vent and conveyor drifts.
It is the object of the present invention to broaden the sphere of application
and increase the effectiveness of working seams by a selective method, and also to
enhance the technical potential of the machine in bulk and selective methods of
extracting minerals.
To achieve the object that has been set, the claimed invention, a face-working
machine, comprises the following set of substantial features : a housing and two
actuating elements disposed at the ends of the housing, the actuating elements being
in the form of arms
rotatable in the vertical plane, provided with a built-in drive and a cutting
screw conveyor; each arm is connected to the housing of the machine by means of a
bracket at one end of which the arm is hinged, while the other is movably mounted
in the guides of the housing of the machine, enabling frontal movement of the arm
against the face with the help of a hydraulic cylinder by an amount equivalent to the
intake capacity of the screw conveyor.
The claimed invention has the following distinguishing features over the
prototype: each arm is connected to the housing by means of a bracket at one end of
which the arm is hinged, while the other is movably mounted in guides of the
housing of the machine, enabling frontal movement of the arm against the face with
the help of a hydraulic cylinder by an amount equivalent to the intake capacity of the
screw conveyor.
According to the information available to the authors, the set of substantial
features characterizing the substance of the claimed invention is not known from the
prior art. thus permitting to come to the conclusion that the invention meets the
criterion of "novelty".
A comparison of the claimed face-working machine with the prototype permits
one to conclude that the prior art machine does not contain features similar to the
substantial distinguishing features of the claimed machine.
The set of features of the claimed technical solution is distinguishable over the
prototype and over known analogs, and is not obvious from the prior art. Therefore,
the authors believe that the
subject matter is novel and has inventive height.
The invention also has inventive height because a combination of features,
which is the connection of each arm to the housing of the machine by means of a
bracket at one end of which the arm is hinged, while the other is movably mounted
in guides of the housing of the machine enabling frontal movement of the arm
against the face with the help of a hydraulic cylinder by an amount equivalent to the
intake capacity of the screw conveyor, solves the problem of the invention : to
broaden the sphere of application and increase the efficiency when working seams by
a selective method, and also to enhance the technical potential of the machine in
bulk and selective methods of extracting minerals. These features are interconnected
in such a way that one of them is removed, the technical result, which is provided
with the invention, disappears.
The set of substantial features, characterizing the substance of the invention,
can be used in mining by obtaining a technical result lying in efficiently working
seams of a mineral by the bulk method and the selective method, leading to an
achievement of the object set, thus permitting one to come to the conclusion that the
invention meets the criterion of "industrial applicability".
The substance of the claimed invention is explained graphically, the figures
showing :
The claimed face-working machine comprises a housing 1 with feed
mechanisms 2 and 3, two actuating elements in the form of arms 4 and 5 having a
built-in drive 6 and 7, and screw conveyors 8 and 9. Each arm is connected to
housing 1 by means of brackets 10 and 11. Arms 4 and 5 are hinged at one end of
each bracket, while the other is mounted in guides 12 and 13 of housing 1. Hydraulic
cylinders 14 and 15 provide frontal movement of the brackets 10 and 11 together
with arms 4 and 5 against the face by an amount equivalent to the intake capacity of
the screw conveyor.
The machine operates as follows. For extracting seams of a mineral by the bulk
method, both arms 4 and 5 are pushed back from the face into the machine with the
help of hydraulic cylinders 14 and 15. At the same time brackets 10 and 11 move
along guides 12 and 13, providing the necessary equal reach of screw conveyors 8 and
9 with respect to housing 1. In this state the machine is ready to work in the bulk
method.
For working seams in the selective method, one or the other screw conveyor
must periodically obtain frontal movement against the face. So, when working a
seam which has a rocky interstratification in the middle section thereof, the order of
working the machine is as follows : one of the screw conveyors occupies an upper
position and, with the help of bracket 10 and cylinder 14, is pushed out frontally
against the face along guides 12 by an amount equivalent to the intake capacity of
the screw conveyor.
In this position the machine moves through the rock, extracting the upper productive
batch of the seam. After passing through, the upper screw conveyor returns to its
original position, i.e. it is pushed back into the machine. Having moved the whole
machine on a trough-like foundation against the face, the following operation with
both screw conveyors provides an extraction of the rocky interstratification.
For the following third operation, the upper screw conveyor is moved out
against the face by an amount of its intake capacity and provides an extraction of the
immediate upper productive batch of the seam, while the lower screw conveyor,
which, with respect to the face, lags behind the upper screw conveyor by an amount
of its intake capacity, works off the lower productive batch of the seam. Before the
fourth operation, the main conveyor together with the machine moves against the face
by an amount of its intake capacity, while the upper screw conveyor is pushed back
into the machine; as this takes place, both screw conveyors provide an extraction of
thr rocky interstratification. Further, the third and fourth operations alternate.
An analogous order of operation of the machine is possible when there are two
or more rocky interlayers in the thickness of the seam.
According to constructional studies, the claimed invention can be utilized in the
national economy, and in comparison to the prototype, it has the following
advantages :
The sphere of application of such a machine is wider, i.e. it can be used without
any structural change in both the bulk and selective methods. The efficiency of its
utilization is increased due to the universal construction of its activating elements.
which provide an extraction of productive batches and rocky interstratifications. The
technological potential of the machine has been expanded because its actuating
element can expeditiously regulate the breadth (range) of its intake capacity.
