The invention relates to mining, in particular to integrated devices for the development of placer mineral deposits and formations of minerals.

It is known mining and transporting equipment used on mnogoshipovyh the drug containing Kovshova frame, Kovshova chain, which consists of a one-piece ladles, equipped with removable visors and connected to the bucket by means of rivet or a locking connection (Century, Leshkov. Development of placer deposits. M.: Nedra, 1985, S. 391-393).

Known equipment is a very bulky design and the motion screener circuit having a large energy consumption. Other disadvantages screener chain can be attributed to the fact that as we ascend in the process of transportation of the bucket is washed with a large amount of sand dredging in the incision that causes loss of useful component.

The closest technical solution, essential features, is groundsamine device dredger, comprising a screw, comprising mounted on a shaft carrying a spiral belt (A.S. SU # 1798441, 28.02.1993, CL E 02 F 3/88).

However, when using suction head; it dredger on alluvial deposits and man-made accumulations of mineral raw materials as t is unsporting body Draghi all material will be transported to the enrichment process, that will lead to significant costs for transportation, additional enrichment and gravel dumping. These costs are not effective because of large classes developed alluvial Sands deposits do not contain useful components.

The main object of the invention is the reduction of operating costs by combining the processes of transportation and classification.

This object is achieved in that the transporting equipment Draghi made in the form of a screw, comprising mounted on a shaft carrying a spiral belt, equipped with a U-shaped trough and a perforated drum with a reinforcement in the form of a helical ribbon having a cross-sectional curved shape curved in the direction of movement, while the drum is installed in the upper part of the U-shaped trough, and the bottom set screw.

The screw diameter is 1-0,5 diameter of the perforated drum. If the diameter of the auger will be more than 1 diameter of the perforated drum, this will cause the auger is not loaded as part of the transported material continues to move through a perforated drum that will lead to an increase of metal construction, and therefore, additional costs for manufacturing equipment. If the diameter of the auger will makes the 0.5 diameter of the perforated drum, this will lead to an overload of the screw, and a portion of the transported sand transported by a perforated drum, the size of which is less than the width of the gap perforation, be discharged into a dump, in this regard, will overload the equipment and the impossibility of a stable operation.

In relation to the prototype of the claimed invention includes the following features: auger, comprising mounted on a shaft carrying a spiral belt.

In Fig. 1 shows a transporting equipment Draghi, in Fig. 2 - section a-a of Fig. 3 - section B-B.

Transporting equipment Draghi, including auger, comprising transporting a spiral belt 1 and the shaft 2, provided with a perforated drum 3 and the spiral ribbon 4, and the drum is installed in the upper part of the U-shaped trough 5, and at the bottom of the trench is set auger.

Transporting the equipment operates as follows.

During the rotation of the perforated drum 3 and a spiral belt 4 is captured by transported soil. Then the material under the action of inertial forces arising from the rotation, moves along a perforated drum 3. Under the action of gravitational forces transported the material begins to be classified according to the classes of the size of the undersize and oversize. Undersize particles are transported by a screw, ostasis from the transporting helical tape 1, mounted on the shaft 2 on the surface of the U-shaped trough 5, and further processing the installation. Oversize class size continues to move through a perforated drum and is discharged into the dump.

The advantages of the proposed design:

- perforation of the drum will allow the classification of sand directly in transportation that will reduce the cost of enrichment of coarse Sands;

- additional set screw in the bottom of the U-shaped trough, allows to transport small fraction, which was obtained by classifying the transporting drum, to the level of processing equipment with the lowest cost.

Transporting equipment Draghi, including auger, comprising mounted on a shaft carrying a spiral belt, characterized in that it is provided with a U-shaped trough and a perforated drum with a reinforcement in the form of a helical ribbon having a cross-sectional curved shape curved in the direction of movement, while the drum is installed in the upper part of the U-shaped trough, and the bottom set screw.
