FIELD: agriculture; machine building.
SUBSTANCE: invention relates to the field of agricultural machine building. Device for soil treatment for soil with grass coating, primarily soil sports or physical training grounds, especially with device for conditioning grass coating, comprises a bearing device, several directly or indirectly fixed on it injection elements, a device for providing a fluid medium, which is hydrodynamically connected to the injection elements, and at least one drive device, by means of which injection elements are, first, lowered and lifted relative to the carrier and, secondly, movable along the treatment direction of the soil treatment device. During lowering, injection elements are submersible in soil for injection into soil on processed section of fluid medium. Injection elements, when entering the soil, remain fixed on the treated section at relative displacement relative to the carrying device moved in the processing direction. Injection elements after injection of fluid medium are lifted and moved in direction of treatment relative to bearing device. During the next lowering into the soil, the injection elements are submersible at the next treated section, which is located in the processing direction after the said treated section. Proposed device comprises holding device with holding part whereon injection elements are secured. By means of at least one drive device the holding device is connected to the bearing device, which enables to jointly lift and lower the injection elements, and also to move them along the processing direction.
EFFECT: enabling treatment of large soil surfaces.
