The invention relates to the transport industry, in particular for transport with the roller elements of the terrain.

Famous boat with the propeller, made in the form of two symmetrical with respect to the median plane of the vessel partially submerged screw (arhimedova screws) with non-parallel axes of rotation (Application for invention of the Russian Federation No. 96114837/28, IPC WV 35/00, publ. 27.10.1998,).

A disadvantage of the known vehicles is their inability universal use, in particular for movement on land.

It is also known a vehicle that includes a chassis with the engine and frame and two supporting-way screw elements in the form of cylinders with progolosovali shafts and rigidly attached perpendicular to its outer surface a helical blades (Patent RF № 2229998, IPC 62D 57/00, publ. 10.06.2004, prototype).

The disadvantage of this vehicle is also the impossibility of their universal use, in particular for the movement of water and marshland.

The basis of this decision laid the task of providing transportation by water, land and marshland. This also solved the problem of increasing the maneuverability of the vehicle, reclamation of surface seagrant and collect oil and other contaminants from the surface of the water.

This problem is solved due to the fact that the boat-track vehicle including a chassis with the engine and frame and two supporting-way screw elements in the form of cylinders with progolosovali shafts and rigidly attached perpendicular to its outer surface a helical blades, the engine is equipped with hydraulic pumps and hydraulic motors, the frame is made in the form of plots of the longitudinal beams with swivel-connected to console her arms, the free ends of the holding with one hand the stators of the motors, and on the other, the bearings of the shafts of the cylinders, hollow cylinders sealed; beam pairs are connected by hydraulic jacks; connections traverse with the stators of the motors, bearings bearings and hydraulic jacks made the hinge; and equipped with a tank for collection of garbage and oil spills from the surface of the water.

Implementation characteristics of the invention leads to a new effect: when moving cross (swamp) areas and the distortions of the cylinders relative to each other in the transverse direction of the body is always in a horizontal position; changing with the help of hydraulic jacks angle between the cross beams, you can adjust the speed of movement of the vehicle; the availability of containers for collection of garbage and oil spills which allows you to use the device for active cleaning the surfaces of bodies of water.

The invention is illustrated by the diagrams: figure 1 - General view of the device; figure 2 - frame with the roller elements, the cross beams and hydraulic jacks; figure 3 is a side view with the container; figure 4 - scheme with different angles between the cross beams.

Boat-track vehicle (figure 3) includes a housing 1 with engine, hydraulic pumps 2 and 3 to the frame 4 and the hinges 5 on it front and back, attached to the left and right of the bar 6, placed at an angle to each other in the form of consoles torsions, to the free ends of which are pivotally attached to the stators of the motors 7 and the bearings 8 for shaft 9 is sealed cylinder 10 with attached spiral blades (augers) 11.

The left and right of the bar 6, symmetrically in front of and behind the boat, are interconnected by a hydraulic Jack 12 through a swivel head 13. Cavity of the hydraulic jacks 12 and the working space of the hydraulic motors 7 via remote control reported hoses, high pressure hydraulic pumps 3.

For collection of garbage and oil spills from the surface of reservoirs boat-track vehicle equipped with a capacity of 14 in the form of a truncated pyramid, the top of the back relative to the direction of movement of the boat. The ground plane is open and the plane of the top of a truncated pyramid is equipped with a filter 15 with adsorbent that removes greasy stains.

The inventive device is TWT operates as follows.

When driving on the ponds and marshes of the cylinders 10 are floats, and screws 11 create horizontal forces for the movement of boats on their surface. Thus regulation of speed, traction and maneuverability are carried out by changing the angle between the arms 6, so that changes the pitch angle of the blades of the screws 11 to the longitudinal axis of the device, and the rotational speed of the shafts of the motors 7.

If necessary, the device can be used for remediation of soil for planting plants, as well as for cleaning the surfaces of water bodies from pollution. For this purpose, the device mesh tank 14 with the filter 15. Fluid with debris enters the cavity of the container 14 and flows out through the filter 15 and the contamination remains in the cavity of the container 14.
