The invention relates to mining equipment, namely, devices for the development of placer deposits of minerals dredging method.

Known Draga containing the pontoon, the working body (bucket frame with bucket chain), boot tray, dredging the barrel (drum screen), mineral processing equipment, the discharge tray, tape pebble spreader and Eveline deck (see Vgisc. Theory and practice of development placers mnogozachatkovye dredges. - M.: Nedra", 1980 - s).

The rock mass coming in dredging the barrel of the bucket chain through the loading tray, after disintegration and screening is divided into two size class: +16 -16 mm and mm Class -16 mm, passing through the processing equipment arrives on Eveline deck and later in athelny blade. Class +16 mm through the discharge tray is fed to the tape pebble spreader and then to pebble pile. Rigid mount evalnih and gravel spreaders is the cause of what is happening padding the sides of the dredging cut epilinum and pebble dumps. As a result, when the dredge mutually opposite passages (as it happens in most cases) are formed miodowy pillars (figure 3), the loss of sand which can be more than 10% (according to Vgisc).

The technical result of the image the program is to increase the efficiency of development of placer mining dredges and reducing loss of the mineral in mihalovich the pillars.

The technical result is achieved by the fact that Draga, including pontoon, working body, boot tray, dredging the barrel, mineral processing equipment, the discharge tray, gravel spreader and Eveline deck, characterized in that the pebble spreader is installed on the pontoon can be rotated in a horizontal plane, and the tail part evalnih decks made with the possibility of rotation in the horizontal plane.

Before you begin Draghi produce rotation in the horizontal plane of the spreader pebble and evalnih decks in the direction opposite to the direction of testing the following Zachodni (tape), to the desired angle. This will not happen to the bedding (or it will be minimal) dumps the side of the section, subject to subsequent testing. During the reverse course Draghi appears possible to develop Zachodni without leaving mihalovich pillars, i.e. without loss of the mineral.

Figure 1 shows Draga, figure 2 is a top view of figure 1, where 1 is the pontoon, 2 bucket frame with bucket chain, 3 - boot tray, 4 - dredging barrel, 5 - mineral processing equipment, 6 - discharge tray, 7 - tape pebble spreader, 8 - Eveline deck, 9 - rotary platform pebble the spreader, 10 - ropes, 11 - winch, 12 - rotary part evalnih Colo is.

Figure 3 shows the scheme of education methodologi pillar, where 13 - move straight Draghi, 14 - pebble blade, 15 - athelny blade, 16 - methodology pillar, 17 - reverse Draghi.

The dredge operates as follows. Before developing a new Zachodni produce rotation in the horizontal plane pebble the spreader 7 and evalnih decks 8 in the direction opposite to the direction of testing the following zagadki, to the desired angle. Turn pebble the spreader 7 is carried out using winches 11 and the rope 10, the turning tail evalnih decks 8 is performed using the rotary device 12, based on the known rotary mechanisms (hydraulic, mechanical, and others). When developing dredge Zachodni 13 mountain mass of the bucket chain 2 comes in dredging the barrel 4 through the feeding tray 3, where it after integration and screening is divided into two classes according to the size: +16 -16 mm and mm Class -16 mm, passing through the processing equipment 5, is fed to Eveline deck 8 and later in athelny the blade 15. Class +16 mm from dredging the barrel 4 through the discharge tray 6 is supplied to the tape pebble spreader 7 and later in pebble blade 14. Due to the fact that pebble spreader 7 and aft evalnih decks 8 is rotated in the horizontal plane in the direction opposite to the direction of the development of the next Zachodni 17, to the desired angle, is excluded padding the sides of the next zagadki and reverse the course Draghi 17 there is a possibility of development of zagadki without leaving mihalovich pillars 16, i.e. without loss of the mineral.

Draga, including pontoon, working body, boot tray, dredging the barrel, mineral processing equipment, the discharge tray, gravel spreader and Eveline deck, characterized in that the pebble spreader is installed on the pontoon can be rotated in a horizontal plane, and the tail part evalnih decks made with the possibility of rotation in the horizontal plane.
