The machinery can be fitted onto a vehicle, either an automotive or towed one, and move to the locations where the user desires to ejection the soil.

Technology so far has not constructed similar pieces of equipment.

The effort to research a technical construction for the operation of such type of machinery derived from the need to eject soil from an autonomous mechanism that sucks the soil from the ground onto which it is located, by digging it, for uses that can become useful in several technical works.

Furthermore, ejection of soil can serve the purpose of building barracks for the protection from water leakage in cases of storm or for the purpose of throwing soil over burning forests or bushed regions.

Another objective of the present invention is to face problems of strength, functionality and service life duration of the invention, by effecting various construction solutions that will be presented in detail in the following detailed description where the aforementioned and the other advantages of the present invention will become evident.

The invention will be understood by specialists in the field with reference to the drawings which accompany the present invention where certain preferred industrial applications of the invention are illustrated, where: Drawing 1 illustrates a plan view of the equipment from the top.

Drawing 2 illustrates a view of the equipment from the side, fitted on a wheeled towed carrier.

Drawing 2 illustrates a view of the equipment from the side, assembled on a track layer vehicle.

With reference to one selected indicative example of industrial application of the invention, a numbering of the principal parts of the object is given below, with reference to the respective numbering of parts in the attached drawings, where these are illustrated in an indicative descriptive illustration out of scale, though in an analogy of relative sizes of them.

According to the preferred indicative application of the invention, the principal parts of the invention are the following: 1. A burr drill for excavating and shredding of agricultural fields. It shreds the soil underneath it and ejects it towards the selector 4.

2. A hopper fitted along the length of the burr drill 1 and the selector 4 which bears internally a strong suction turbine 3.

3. A suction turbine 3 located assembled at the bottom of the hopper 3.

4. A selector. A perforated metallic surface where the shredded soil lumps fall after being dug by the burr drill 1 and pass through the apertures for being sucked by the hopper 2.

5. A tube for ejection of soil, assembled at the bottom of the hopper 2, after the turbine 3. The tube is directed with a suitable mechanism or is rotated by the displacement of the vehicle onto which the mechanism is fitted, towards the location where the soil ejection is desired.

6. A carrier or platform seating on wheels, onto which the mechanism is fitted for transportation to locations, where its use is desired.

7. Wheels of the carrier.

8. Tracks of a vehicle where the invented mechanism is fitted for transportation through rough ground.

9. The excavator of the track layer vehicle which is used in auxiliary works in the case where the vehicle is used for putting off forest or bushed regions fires.

10. Internal combustion engines or electric motors. These are used for moving all the above described parts and individual mechanisms.

The operation of the invented machinery is as follows: The burr drill 1, or even another suitable equipment in some other variation of construction, digs the surface of the soil and ejects the pieces of soil towards the selector 4 which bears apertures through which only soil lumps of a small cross section pass. It separates pieces of wood or other big objects from the soil and rejects them back to the ground.

After the broken soil lumps pass through the selector 4, they are sucked by the hopper 2 at the bottom of which a strong turbine 3 is fitted which sucks the broken soil lumps and drives them to the ejection tube 5.

The strong pressure developed by the turbine 3 inside the tube 5 ejects the broken soil lumps at a sufficient distance away from the mouth of the tube.

All the above parts and units of the invented piece of equipment are set into motion by the internal combustion engine 10 located onto the carrier or platform. The individual mechanisms may be also set into motion by an electric motor, should the provision of electricity be possible.

If it is desired to use the invented equipment for putting of fires in forest or bushed regions, the most suitable vehicle for transporting the mechanism to the burning regions is the track layer vehicle, especially if the latter also features an excavator 9.

This vehicle can penetrate the burning region and approach the focus of the fire, onto which it ejects shredded soil.

By ejecting soil to the burning surface, a continuous dust cloud is formed which cuts off the oxygen supply from the burning surface. Simultaneously, the soil granules cut off the small pieces of branches, leaves and other small pieces of the trees and bushed es, resulting in faster putting off of the fire in the forest or bushed region.

It must be taken into account that the object of the invention is not limited to the above example. The achievement of the invention is possible with other means and methods of construction, other parts and other mechanisms which remain within the views of the present description.

It must be noted here that the present description of the invention was effected with reference to certain only indicative examples of application of it. Thus, any modification or variation regarding the shape, the form, the dimensions, the materials used and the parts for its construction and assembly is considered to be contained within the scopes and views of the present description.
