The invention relates to the technology of handling and can be used for unloading trucks, railcars, trucks and other vehicles from wet sticky capillary-porous materials of different nature.

Closest to the claimed device is a device for cleaning vehicles, containing the constant current source, the electrodes attached to the body of the vehicle, insulated is either using a flexible elastic elements with the walls of the vehicle.

The disadvantages of this device are braking paged material electrodes, the position of which in the vehicle fixed by means of levers, and the impossibility of optimal placement in the volume of the material of the electrodes, connected by a flexible elements with the walls of the vehicle.

Thus, the prototype does not provide effective discharge wet sticky materials, as required for electroosmotic processing electrodes have a significant resistance to movement of the material, and their position in the unloading process does not change.

The challenge which seeks the invention is a device for unloading vehicles from wet sticky materials, ensuring the reduction of braking forces of the unloaded material.

This technical result is achieved in that the device for unloading vehicles from wet sticky materials containing constant current source, electrodes mounted on the body of the vehicle, isolated from the body via electrical nodes end and connected by conductors with one of the poles of the source is constantly the ability of their rotation with the movement of the material. The electrodes can be made in the form of rods mounted on one or more rotary beams, perpendicular to the direction of movement of the unloaded material.

Additionally, the device may contain one or more plate electrodes placed on folding or pivoting the body side of the vehicle. The electrodes can be made in the form of rods mounted to rotate on one or more beams that are parallel to each other in the direction of movement of the material during unloading.

Efficient unloading of wet sticky materials electroosmotic method provided under the following conditions:

the electrodes should be placed in the volume of the material so as to ensure uniform current distribution on the working surface of the body when the tilt of the body at a given angle;

in the transmission of current through the material and electroosmotic moisture on the surface of a body of adhesive and frictional force of the clutch must be reduced to values Satybaldy component strength weight;

the holding force of the material of the electrodes must be so small, ctcae from the prototype provided the simultaneous fulfillment of all these conditions, what determines the novelty of technical solutions.

In Fig. 1 schematically shows a device for unloading of the vehicle; Fig. 2 - design of the electrode system, consisting of rods mounted on the rotary beam; Fig. 3 - node I in Fig. 2; Fig. 4 - design of plate electrode mounted on pivoting the vehicle; Fig. 5 - a device in which the rod electrodes placed on two rotating beams perpendicular to the direction of movement of the material during unloading, Fig. 6 is a device in which the rod electrodes are mounted to rotate on the gully in the direction of movement of the material.

Device for unloading vehicles from wet sticky materials contains the constant current source 1, the electrodes 2, the conductors 3, the switching device 4.

The size and location of the electrodes are chosen to provide a sufficiently uniform distribution of current over the entire surface of the body that provides wetting the entire surface of the moisture is released in the process of electroosmosis, and reduce the adhesion and frictional forces. The electrodes are set in the 7 electrical separation from the sides of the body 6 and the dielectric spacers 8. The plate electrode 2 (Fig. 4) is fixed on the folding or pivoting the Board 9 and is isolated from it by using the dielectric plate 10. Isolation and mount on the back beam 11 (Fig. 6) that are installed parallel to the direction of movement of the material is similar. Design of beams is selected taking into account the convenience of downloading material.

The film thickness of the moisture that is released on the surface of a body is proportional to the current density and the time of his passing. The value of the current density at which it is advisable to produce electroosmotic processing is determined for each material experimentally and usually varies from one to several tens of a/m2.

The device operates as follows. In accordance with the sign elektrokineticheskogo potential paged material switches the switching device 4. For example, for soil electrokinetic potential is negative and the electrodes are connected to the positive pole of the DC source 1, and the body to the negative. This forms an electrical circuit: plus source 1, the conductors 3, the electrodes 2, isolated from the body material, cuso what about the wet material phenomenon of electroosmosis. With this direction of the current on the surface of the body stands out moisture, provides a decrease in the adhesion and frictional forces of adhesion of the material to the work surface. When lifting the body begins the movement of material. When the electrodes 2 are rotated during movement of the material in the direction of motion, almost without impeding discharge. This ensures efficient unloading of the vehicle against wet sticky material.
