Description

In mining, self-loading scrapers are used to deliver coal from the bottom, with the scraper taking away the upper layers of the hewn coal first and moving it with ropes. In order to guide the scraper to the middle part of the black coal, a method is proposed in which the scraper rope, in the production of a log, is connected to a bracket installed on the bed of the hem mash, and is thus pulled along the cut, and after the stripping is completed, the coal scraper is moved by means of a winch. For the purpose of entering the scraper into the bulk of the broken coal and capturing it, with this method, a scraper with a rotary valve is proposed, which, unlike the known ones, is attached to the bottom of the scraper, which has a nose for penetrating into the coal.

In FIG. 1 shows a diagram of dragging a scraper rope over the cut; fng 2 - view of the proposed scraper from the side; FIG. 3 - view it in the plan.

The proposed method is as follows. In the loop of the rope / winch 3 (Fig. 1), the scraper 4 is included with its end parts - nose b and grip 5, with the nose of the scraper facing the cutting machine. On bed bed cutting maschiny

reinforced brace with rollers 2, through which the rope loop is thrown. With the full passage of the cutting edge, the rope is pulled through the cut and when the machine stops, the rollers 2 serve as a direction for moving the rope, and therefore the scraper 4. The latter consists of a trough-shaped box with a bottom 4 to which it is fixed in front of it or on hinges 7, with the possibility with a slight turn in relation to the bottom, a pointed nose 6. On the back of the scraper has a grip 5.

In its middle part, the scraper has a flap 9 attached by hinges 8 to its bottom, rotating 90 ° from the bottom plane in the direction of the nose to the stops. After the cutting machine is finished and the coal is crushed, the winch is turned on and the scraper, moved by the kynat /, nips into the middle part of the lined coal, which fills its entire working space. During the return of the winch 5, the scraper for the gripper 5 is moved back and the coal in the scraper lifts the flap 9 in a vertical position (Fig. 2).

The coal remaining in the slit-shaped cavity of the scraper is removed at the place of discharge of the cut coal,

The subject matter of the invention.

1. A scraper loading method, characterized in that, in order to pull the scraper rope / (Fig. 1) along the cut to guide the scraper to the middle part of the charcoal, the scraper rope 7 during production

The cut is connected to a bracket mounted on the bed of the cutting machine. 2. To carry out the loading method according to claim 1, the use of a self-loading scraper with a rotary shutter, characterized in that the shutter P is attached to the bottom 4 of the scraper, equipped with a nose 6, is ush; it is integral with the bottom or connected to it with the help of hinges 7
