Abstract

FIELD: machine building.

SUBSTANCE: invention relates to cutter-loaders. Cutter-loader includes a movement mechanism, at least one executor. Axis of rotation of the executor is directed along the movement of the combine to the work face. Executor includes at least one cutting head with a drive fixed to the handle so that the axis of head rotation is directed along the combine movement to the work face. Axis of handle rotation coincides with the axis of executor rotation. Cutting surface of the cutting head has a shape that ensures the destruction of the work face both along the contour of handle rotation with the cutting head, and in the direction of movement of the combine on the work face.

EFFECT: technical effect: to provide uniform removing of rock sheets.

Description

The technical field to which the invention relates.

The invention relates to the mining industry, and in particular to continuous mining combines, and is intended for mining in underground mining.

State of the art

Known tunneling shearer (RF patent No. 2161252 (C1)), comprising a swept working body, a body in the form of a welded frame structure, a pumping station with a system of hydroblocks, support skis and support knives.

The disadvantage of this solution is the impossibility of cutting the executive tool evenly on the entire surface of the face, as well as the difficulty in obtaining a given production profile due to the use of hydraulic control of the boom of the executive body with manual control.

Also known is a roadheader (AS No. 1265318 (A1)), which includes a housing, a planetary actuator, fender devices, a conveyor and chassis, a hydraulic and an electrical system. This device is taken as a prototype.

The disadvantage of the prototype is to obtain an uneven fraction of the broken rock during the rotation of the executive body, increased wear of the cutters due to the constant change of position during portable rotation, as well as the complexity of the design due to the use of bevel gears when transmitting rotation directly to the cutting head.

Disclosure of invention

The technical result of the present invention is to provide more uniform removal of rock layers, to ensure destruction of the face both along the contour of rotation of the handle with the cutting head, and in the direction of movement of the combine to the face.

This is achieved by the fact that the cutting head is fixed to the handle of the executive body so that its axis of rotation is directed along the movement of the combine to the face, while its cutting surface is flat, and preferably has a profile of the body of rotation.

Comparison of the inventive mining machine with the prototype allows us to conclude that the latter does not have signs similar to the significant distinguishing features of the claimed invention.

Also, the invention does not follow explicitly from the prior art, therefore, the authors believe that the object is new and has an inventive step, since when eliminating such a technical solution as a cutting head mounted on the handle of the actuator so that its axis of rotation is directed along the movement of the combine, has a flat, and preferably with a profile of the body of revolution, cutting surface, the ability to ensure uniform removal of rock layers and ensure destruction of the face as per the outline of the rotation of the handle with the cutting head, and in the direction of movement of the combine to the bottom, and therefore the technical result also disappears.

Description of drawings

The invention is illustrated graphic materials, which depict:

FIG. 1 - Mountain harvester. Option with two executive bodies.

FIG. 2 - The layout of the cutting head relative to the chest face. Options.

FIG. 3 - Scheme of rotation of the handles with cutting heads.

FIG. 4 - Mountain harvester. Option with two actuators and two cutting heads.

FIG. 5 - Mountain harvester. Option with one actuator and three cutting heads.

The implementation of the invention

The mining machine contains a movement mechanism (1), at least one fender (2), at least one actuator (3) with at least one rotating cutting head (4) fixed to the handle (5).

The invention works as follows.

A mountain harvester using the movement mechanism 1 (Fig. 1) moves along the working line until the cutting heads 4 of the actuator 3 come in contact with the face. The cutting head 4, rotating on the handle 5 of the actuator 3, layer-by-layer removes the rock, forming a contour of the development of a given shape, and fenders 2 form the soil and roof, respectively. Processing the face in the direction of movement of the combine, rotating around its axis, the cutting head 4, additionally making circular movements by means of the handle 5, ensures the destruction of the face along the contour of rotation of the handle.

It should be noted that the given configuration of the mining combine and its elements are a special case and can be performed differently, the possibilities themselves that such a configuration provides and which, nevertheless, can be achieved by a number of other design features, are essential. For example, the cutting heads can be two (Fig. 4), three (Fig. 5), or more, they can be in the form of a cone, a hemisphere of a disk or screw (Fig. 2) and other bodies of revolution, and the handles, respectively, can have more complex configuration, etc. In addition, the inventive design can be used in the previously known from the prior art layout of a mining machine with two actuators rotating in the opposite direction (Fig. 3).

Also for the claimed mining machine in the form described in the claims, it is possible to manufacture and use it using means and methods known prior to the filing date of the application.

The claimed invention can find wide application in the mining industry for conducting mine workings, in particular continuous miners, used in mining underground.

Claims (1)

A mountain harvester comprising a movement mechanism, at least one actuator, characterized in that the axis of rotation of the actuator is directed along the movement of the harvester to the face, the actuator comprises at least one cutting head with a drive, mounted on the handle so that the axis of rotation of the head directed along the movement of the combine to the bottom, while the axis of rotation of the handle coincides with the axis of rotation of the actuator, and the cutting surface of the cutting head has a profile that ensures the destruction of the bottom to both along the contour of rotation of the handle with the cutting head, and in the direction of movement of the combine to the bottom.
