Description

Description of the invention

The invention relates to mining equipment and can be used to carry out mining 2 during underground development of minerals.

A well-known tunneling combine, which includes a drilling executive body, berm cutters, cutting drums, a shield of four sections with attached sides and cuffs, behind which there is a conveyor, a hydraulic system with an oil station and a control panel, and a driver's seat |11.

The disadvantage of this harvester is that during mining, when the mountain massif is destroyed by 70 executive bodies, a large amount of dust is formed, penetrating through the hole above the conveyor in the barrier shield to the operator's workplace, worsening his working conditions, threatening the acquisition of occupational diseases.

The task of the invention is to reduce the dustiness of the driver's workplace during the work of the harvester.

The technical result is achieved by the fact that the mining combine, which includes crawler trolleys, 12 drilling executive bodies, berm cutters, cut-off drums, a shield of four sections with sides and cuffs attached to them, a conveyor with grooved sides, a control panel for the hydraulic system, the combine electrical equipment control station and the driver's seat, additionally contains two dust protection flaps with a locking mechanism, mounted hingedly on the grooved sides of the conveyor at an angle to the vertical.

Fig. 1 shows the mining combine harvester, Fig. 2 shows the protective shield of the combine with dust protection flaps, Fig. 3 shows their side view.

The mining combine includes crawler trolleys 1, drilling executive body 2, berm cutters 3, cutting drums 4, barrier shield 5, conveyor 6 with grooved sides 7, control panel 8 for controlling the hydraulic system of the combine, station 9 for controlling its electrical equipment, driver's seat 10. with

The barrier shield 5 is located on the harvester in such a way that it blocks off the entire surrounding space. (9 with dust-generating cutting bodies 2, 3, 4 from the rest of the spent space. It consists of four sections 11, 12, 13, 14 with attached sides 15, 16, 17, 18 with cuffs 19 from the conveyor belt. To the grooved sides 7 of the conveyor 6 are hingedly attached to the hinges 20, two dust protection flaps 21 and 22 at some angle to the vertical. The dust protection flaps on the side of the driver's seat 10 are equipped with a locking mechanism. It is made on each flap 21 and 22 in the form of rigidly attached bushings 23. Bushings 23 The valves 21 are located coaxially (in the horizontal plane) with the bushings 23 of the valve 22, forming pairs. In the holes of the pairs of bushings 23 of the valves 21 and 22, levers 24 are inserted with the possibility of being pushed out of the bushings 23. On one of the valves, the bushing 23 is opposite, but on some at a distance from them, there are stops 25. One end of each of the levers 24 is bent so that the lever can be extended only in one direction to the stop 25, freeing the sleeve 23 of the adjacent damper. After that, the damper valves 21 and 22 have the ability to turn on hinges 20. Dampers along the outer contour have attached cuffs 26 from the conveyor belt.

The mining combine works in this way.

The ore is reflected by the drilling executive body 2 in the mountain massif, forming a niche with a cylindrical cross-section. Feed is the working movement of the harvester to the slaughter with tracked undercarriages 1. Berm cutters Z 70 beat ore near the ground, changing the cylindrical cross-section to an arched one. The remaining jumpers, o, c are removed by cutting drums 4. These operations are controlled by the driver from the control panel 8 of the hydraulic control system of the combine and the electrical equipment control station 9U, sitting on the driver's seat 10.

During all cutting processes, a large amount of dust is formed in the air, worsening the working conditions and endangering the health of the combine driver.

To protect the space where the driver's seat 10 is located, a protective shield 5 is mounted on the combine from dust. Shield 5 consists of four fixed sections 11, 12, 13, 14 with attached sides 15, 16, 17, and 18 with cuffs 19 from the conveyor belt. Two dust flaps 21 and 22 are hinged to the grooved sides 7 of the conveyor 6 on the hinges 20 at some angle to the vertical so that they are located above the conveyor 6, 1 leaving only space for placing on it the reflected ore being transported. "c 20 Before starting the processes of cutting the rock massif, valves 21 and 22 are closed. To do this, turn both flaps to the combination of the holes of the bushings 23 on the clearance and push the levers 24 into them to the stop of their broken ends, and at the edge of the bushings 23, the flaps 21. Cuffs 19 and 26 from the conveyor belt, attached along the contour of the protective shield 5 and both flaps 21 and 22, provide a comparative tightness of the underburden space and significantly reduce the penetration of dust from there into the workplace area of the combine driver. 25 Access to the executive body is required to drive away the harvester from the created space. To do this, push the levers 24 from the bushings 23 of the valves 21 and 22 to the stops 25 on the valve 21, completely freeing the bushings 23 of the valves 22 and opening them on themselves. When resuming the cutting processes, the valves 21 and 22 are closed in advance and the levers 24 are pushed into the holes of the bushings 23 of the valves. Since there are stops 25 limiting the extension of the levers 24 from both bushings 23, the latter serve as guides 60 for these levers 24 and, since the bushings 23 are coaxial in pairs, the levers 24 are easily pushed. Dampers 21 and 22 are closed. It is possible to set off the massif of the arched section. Since all the sides 15, 16, 17, 18 of sections 11, 12, 13, 14 and flaps 21 and 22 along the contour have attached cuffs 26 from the conveyor belt, a comparative tightness of the fence of the dusty zone is ensured.

Thanks to this design of the Prokhodnytsky mine combine, the working conditions of the driver are significantly improved, 62 and access to the cutting organs of the combine is not impaired.
