Combine for selective concavity of heavy potassic layer with rock interlayer

FIELD: mining.

SUBSTANCE: invention relates to minerals industry, particularly to treating combines for selective concavity of heavy, predominately potassic layers with rock interlayer. Combine for selective concavity of heavy potassic layer with rock interlayer includes casing, on ends of which there are mounted with ability of rotation in vertical plane two handles, each of which is outfitted by integrated rive and screw, and additional cutting block. Additional cutting block contains handle with integrated drive and screw, and is rigidly fixed to casing of combine. Fixed on body basis of cutting block is pivotally connected to carrier and hydro- thruster climbing of handle, which is rigidly connected to slider, installed in guide groove of carrier with ability of displacement with handle to bottom for value not less than width of screw, diametre of which is not more than power of top layer. Additionally end main screws of combine are implemented with diametre of not less than half of power of more heavy layer of stratum.

The invention relates to the mining industry, namely to wastewater treatment combines for selective excavation powerful, mainly potash seams and rock bed.

Known processor for selective extraction mainly potash seams of medium thickness with a layer of waste rock, the power of which is less than or equal to the diameter of the additional auger, which is stationary raised for slaughter in relation to end the main Sneem on value capture for advanced dredging of the upper layer, while notch main screws exposed in the previous cycle of the lower layer of minerals [1].

The harvester works as follows.

Before beginning treatment works additional screw take out the top layer with loading mineral on the face conveyor lagging the main auger. During the reverse course combine additional auger picks naked rock bed with loading breed second main auger. Then changes the direction of the notches, thus outpacing the primary and secondary augers zarabotka on value capture and beat off at the same time the upper-ahead by the amount of grip the screw and the bare bottom layers. In each subsequent cycle begins with the excavation of the rock bed additional auger and ends simultaneously in the capacious top and bottom layer of minerals in the reverse course of the harvester.

The main disadvantages of the combine are a narrow scope limited by seams of medium thickness, in which the power of the rock bed is equal to or less than the capacity of the upper layer. The harvester can't take out two powerful stroke reservoir capacity of the lower layer approaching the total capacity of the upper layer and the rock bed, and with the power of rock interbed greater than the thickness of the upper layer.

The task of the technical solution is to increase the efficiency of selective extraction of thick layers with rock interbed regardless of the capacity of the latter.

The technical result is achieved by the fact that the harvester for selective excavation powerful potash reservoir rock interbed, including the shell, the ends of which are mounted to rotate in a vertical plane, two handles, each of which has a built-in drive and auger, and additional cutting unit comprising a handle with a built-in drive and auger and cutter block is rigidly connected with the machine body, and fixed to the body base cutting block pivotally connected with the bracket and the hydraulic cylinder of lifting of the handle, which is rigidly connected with the slide mounted in the guiding groove of the bracket can be moved along with the handle to the bottom on the value not less than the width of the screw, dia is the Tr is less than the capacity of the upper layer, and end the main combine augers are made with a diameter of not less than half the power of more powerful lower layer of the layer.

Figure 1 shows a General view of the harvester with the dam side; figure 2 is its top view.

Harvester for the selective extraction of thick layers with rock bed includes a housing 1 containing two feeder 2 and 3; and two swivel in the vertical plane of the handle 4 and 5, hinged at the ends of the housing 1.

The handle 4 and 5 with embedded actuators 6 and 7 and screws 8 and 9. Additional cutting unit 10, a base 11 which is rigidly connected to the housing 1 of the harvester has a hinge 12 and 13 for connection with the bracket 14 and the hydraulic cylinder 15 of the lifting arm 16 rigidly connected with the slide 17 can move it with the handle 16 in the guide groove 18 of the bracket 14 to the slaughter by a value not less than the width of the screw 19 with a diameter less than the capacity of the upper layer. Handle additional cutting unit has a built-in actuator 20.

The harvester works as follows.

Each cycle of the harvester performs two working stroke without idling the distant pastures.

Before beginning cleaning work screw 19 with a handle 16 additional cutting unit 10 is put forward to the working face by moving the slider 17 with the handle 16 in the guide groove 18 of the bracket 14, the set screw 19 to the power of the upper layer, poweraqua the bracket 14 with a handle 16 by a hydraulic cylinder 15 in the hinge connection 12 and 13 with the base 11 of the cutting unit 10. Followed by the oblique notch arrival and the recess of the upper layer with loading on the conveyor mineral main screws 8 and 9, located respectively on the handles 4 and 5 of the harvester, which is moved along the rod conveyor with feed parts 2 and 3. After removal of the top layer backward when pushed to the bottom line and extended in the reverse order from the bottom of the handle 16 with screw 19 main screws 8 and 9 beat rock the bed with his power over the power of the upper layer. Moreover, preliminary in the rock bed by a screw 19 of the cutting unit 10 performs two niches for the main screws 8 and 9. When the valve of the conveyor combine to slaughter in the niches place the screws 8 and 9, lifting jacks, respectively, of the handle 4 and 5. If the power of the rock bed less than the capacity of the upper layer, the breaking of rocks carry out or screw 19 of the cutting unit 10, or the main screws 8 and 9. Then change the direction of the grooves and, by the same order the notch of the screw 19 to the upper layer and the main screw 8 and 9 for more powerful lower layer, remove layers of minerals three screws with loading its lagging screw on the AFC. After completion of the excavation layers, valves, conveyor and advancing roof support begins the next cycle of selective excavation powerful potash is about reservoir rock bed.

The use of the proposed solution will effectively introduce selective dredging powerful layers of rock bed for two turns, serial combine with the installed additional cutting unit with drawers on the bottom handle with integrated actuator and the screw, the diameter of which no more than the capacity of the upper layer of the reservoir.
