Mountain harvester

 

The invention relates to the mining industry and can be used in particular for carrying out excavations and sewage extraction. Object of the invention is the expansion of the scope. Mountain harvester includes a housing with symmetrically arranged screws, gearboxes, feeders, motors and control room with seizures. The body is made of two symmetrical halves that are fitted with placed in the plane of symmetry and its end nodes of the link situated on the side of the dam with the possibility of mutual reversal of the two housing parts in a horizontal plane located in the plane of symmetry of the communication node, and the screws supplied with the goaf side of the ring with slots incisors. 3 Il.

The invention relates to the mining industry and is designed for mechanization of mining excavation and mining.

Known tunneling machines, for example, with the Executive of the arrow type RSCC [I], which are intended only to conduct mining that are not used for sewage extraction in love reverse or face a wide swing. Difficult relationship sinking kombinowania.

Known mechanized lining with treatment combines [2], which are used only for mining but not applied to the workings of the impossibility of placing a harvester in the mine workings, there is no unification of the tunnel-mining equipment used in the plane of the coal seam.

Known harvesters uniform series with symmetrically arranged at both ends of the machine body augers, motors, gearboxes, feeders, reference room with seizures [3] (the prototype), but in this version the harvester cannot be applied when carrying out excavation narrow stroke (length combine more width needed for the production, for example when cutting lavas).

Offering mountain harvester differs in that the casing is made of two symmetrical halves that are fitted with placed in the plane of symmetry and its end nodes of the link situated on the side of the dam with the possibility of mutual reversal of the two housing parts in a horizontal plane located in the plane of symmetry of the communication node, and the screws supplied with the goaf side of the ring with slots incisors.

This embodiment allows to unify the harvester is OBrien mountain harvester in stoping; in Fig. 2 - mining combine with sinking; Fig. 3 - supporting skis and spheres (type a-a, Fig. 1).

Mountain harvester (Fig. 1) consists of the Executive body, consisting of two screws 1, 2 of the same diameter, mounted on the machine body of the feeders 3, 4, electric motors 5, 6, avalanche ski 7, 8 and downhole ski 9, 10.

The nodes of the housing of the harvester are arranged symmetrically. In the plane of symmetry on the part of the dam body is equipped with a hinge 11, which allows to fold the two halves of the housing of the combine in parallel to each other in the horizontal plane.

Folded (Fig. 2) screw conveyors, feeders, motors parallel and symmetrical relative to the longitudinal axis B, screws oriented in this case perpendicular to the breast bottom, and the harvester is used for mining. Augers combine with both sides equipped with cutters, for which the dam side is equipped with a ring with slots incisors, allowing the breaking of rock mass mechanical parts of the augers during reciprocating movement of the harvester along the face. The end nodes of the link 13 is fixed to the housing halves interlocks, for example, in the form of a wedge or bolts.

When using mountain harvester motor, when submitting jacks advancing conveyor at the bottom (the harvester is located on the conveyor, such as a corner) Samothrace to contact the breast bottom housings of rotary gears, then alternately moved along and across the face with the help of the feed mechanism of the harvester and cylinders rotary gear, wall framing with smooth right angle to the base. In the process of moving the harvester and removal of strips, for example in roof, augers move to the soil layer by simultaneous displacement along the face and so on until the end of the excavation of all stripes over the entire area of the face, then the cycle repeats.

The machine travels on the face is carried out jacks advancing shields, performs the functions of the temporary roof support and movement mechanism of the harvester on the bottom. At the end, for example, conveyor drift when the development system long poles along the strike-reverse harvester with shields deploy 90ofor mounting the camera, the width of which is 1.5-2 times wider than the conveyor drift. Drilling mounting chamber width is also the same combine by adding the pans of the conveyor face parts, such as angular conveyor, n is o and the harvester are laid in position for cleaning the grooves in the face of reverse swing, which lock the communication node 13 open at both ends of the housing and turn carry on the hinge 11 in the plane of symmetry. With the dam side screws remove the ring 12, interfering in stoping the unloading of the rock mass.

Thus achieved the unification of downhole equipment when carrying out excavations on the formation and testing of the reservoir. Reduced at the junction of the two technologies, installation and dismantling, is conducting mining with temporary support in the form of sections of mehrabi, are provided with smooth walls (sides) develop a right angle to the soil excavation.

The transition from mountain harvester from sinking provisions in treatment at the expense of mutual reversal of both parts of the housing relative to the hinge located in the plane of symmetry with the dam side. Reference dam skis retain their original position, allowing the spherical joints 14 of the brackets with skis combine to occupy the desired position according to the spread of semi-bodies combine. The unfolding of the harvester from stow position after mounting the camera oudestraat screws on the longwall face.

Folding and unfolding is appropriate portable power cylinders relative to the shields and Board production.

For application combines powerful layers with increased clearance, when the elements of the body of the combine are located on a common frame with the supporting ski, the procedure of folding and back halves of the harvester is simplified, as it occurs on the common frame, with the consequent reduction of the frame or lengthening the amount of insertion, the length of which is determined by the width of the two halves combine folded.

Thus the equipment at the mine working is also used for sewage extraction. Achieved the unification of downhole equipment in the plane of the layer. Shipping downhole treatment equipment implemented through the use of this equipment when conducting mining. There is continuity of the process of working out the seam the same downhole equipment. Decreases the intensity of downhole equipment.
