Description

The utility model relates to equipment for mechanized excavation of minerals, in particular to shearers with auger actuators.

The coal narrow combine harvester is known (author's certificate SU No. 307186, published on June 21, 1971), which includes an executive body in the form of an unregulated lower auger and a power-adjustable upper screw auger and a loading device made in the form of two shields, one of the shields mounted on the body of the combine, and the other on the bracket rigidly connected to the body by means of a beam.

The disadvantages of the known device are unstable position of the shield, fixed bracket on the intermediate part located above the conveyor, and a rigidly fixed longitudinal beam to the combine, one-sided console mounting of the loading shield does not preclude its rise above the working soil in the case of retaining soil layer the seam, the shields do not form the direction of flow of coal loaded in the direction of the flow of coal on the downhole conveyor, different effectiveness of stripping the soil with shields fixed on the body of the combine and on the bracket with the intermediate part and the beam.

The executive body of the mining combine is known (author's certificate SU No. 1051265, published on 10/30/1983), including a hub with cutting-loading elements and a loading plowshare, while the cutting-loading elements are made in the form of discs having the shape of ellipses in longitudinal section, the adjacent discs are inclined to each other at the same angle, and the loading plowshare is connected to the hub by means of bushings mounted on the hub, and the braces are rigidly fixed at the edges of the plowshare.

The disadvantages of the invention are the low reliability of the node connecting the loading disks to the hub of the executive body due to the separate mounting of adjacent disks, not effective loading due to the intermittent movement of coal by separate disk blades, the complex connection of the plowshare with the hub with two rods.

Known loading device clearing combine (inventor's certificate SU №473824, publ. 06/14/1975), including the blade with a blade and a frame, while the blade with the blade is connected to the frame by a hinged horizontal axis located behind the plane of the blade.

The disadvantages of the invention are the impossibility of the shuttle mode of operation of the combine, not a stable position of the plowshare due to the console mounting, additional flexible or rigid connection of the device with the body of the combine, limited reliability of the device due to its complex design and large length of thrust; the possibility of frame jamming during movement of the combine and bending of the bottomhole conveyor or raising the frame above the conveyor, which will exclude the possibility of loading.

A coal combine is known (certificate SU No. 1819327, publ. 30/05/1993), which includes a body on which an executive body, a mechanism for moving the combine and a loading shield hinged on the body of the combine behind the executive body are installed during the movement of the combine with the possibility of rotation with the help of an intermediate element, with self-installation of the loading shield in a predetermined position during idling and working stroke of the combine, while the intermediate element is designed as a flexible connection segment, the length of which is equal to no more than Vertical length of a circle formed by a radius equal to the distance from the attachment point of the loading shield to the body of the combine to the attachment point of the flexible connection segment to the loading shield.

The disadvantages of this device are not the possibility of a shuttle-type operation of the combine, the operation of the combine for excavating coal is only one-sided, with the combine moving over the soil during the return stroke, not a good soil cleaning, since the loading board is not regulated on the soil charge.

Known loading plate for excavation combine with a screw executive body (certificate of authorship SU №1467169, publ. 03/23/1989), adopted for the prototype, including a work surface made as part of a truncated cone, a support bracket for mounting the loading plate on a screw executive body, while the axis of symmetry of the working surface of the plate, mounted on the screw executive body, is shifted vertically downwards relative to the axis of rotation of the screw executive body and parallel to the latter.

The disadvantages of the device are incomplete cleaning of the soil in the passive zone between the screw executive body and the bottomhole conveyor due to the fact that the width of the flap grip is limited by the side of the drive body of the executive body, and the impossibility of forming a rational section of the coal flow on the conveyor on the conveyor and stripping the soil.

The technical result is to increase the efficiency of unloading coal from the zone of destruction, loading it onto the bottomhole conveyor while reducing the amount of coal remaining on the soil, and reducing energy consumption for loading when shearers work in long complex-mechanized clearing faces of coal mines.

The technical result is achieved by additionally installing a flap attached to the loading flap by sliding guide supports with the possibility of translational movement along them using a hydraulic cylinder and installed between the loading flap and the bottomhole conveyor at an angle less than 90 degrees to its side, so that the lower edge of the profile is additional the shield is equidistant to the mating surface of the downhole side of the conveyor and installed with a gap.

The device of the executive body of the shearer is illustrated by the following figures:

Loading device excavator with a screw executive body 6 (Fig. 1, 2, 3), includes a working surface of the loading flap 9, made as part of a truncated cone, while the axis of symmetry of the working surface of the loading flap 4 mounted on the screw executive body 6, parallel to the axis of rotation of the screw actuator 6, the support bracket 5 for mounting an additional shield 2 on the housing of the actuator of the executive body 7 of the screw actuator 6, an additional shield 2 fixed on the a guard plate 4 with the possibility of its reciprocating displacement along the sliding guide supports 3 by means of a hydraulic cylinder 1. An additional shield 2 is located between the loading shield 4 and the conveyor 8 at an angle less than 90 ° to the intake side of the conveyor so that the lower edge of the profile of the additional shield 2 is equidistant to the mating surface of the downhole side of the conveyor and installed with a gap. Extraction harvester skis relies on the conveyor 8 with the possibility of longitudinal reciprocating movement relative to the conveyor.

The device works as follows. The cleaning harvester works both according to one-sided and shuttle-like schemes. Before changing the direction of movement of the combine at the end sections of the lava, the positions of the advancing and lagging auger executive bodies in terms of the seam thickness also change. When coal is harvested by a combine ahead, in the direction of movement of the combine, the screw executive body 6 excavates the top pack of coal in the reservoir and unloads the destroyed mass from the ledge to the conveyor 8. The lower pack of the layer is destroyed by the screw 6 lagging behind in the direction of the combine (Fig. 1-3) , which simultaneously unloads the destroyed mass from the zone of destruction by the blades of the screw with the support on the loading flap 4 and on the additional shield 2 and transfers the destroyed mass to the bottomhole conveyor 8. For movement of the combine in the opposite direction along the lava, additional The flap 2 is displaced along the sliding guide supports 3 of the loading flap 4 by means of the hydraulic cylinder 1, and then, together with the loading flap 4, rotates about 180 ° with respect to the axis of the screw actuator 6.

Technical and economic efficiency of the technical solution of the loading device of the excavation combine with auger actuator consists in forming a steady stream of coal from the zone of destruction to the conveyor with less resistance to its movement, with improved soil stripping at the bottom, with a decrease in the intensity of circulation, grinding of coal, dust generation and energy costs.
