Abstract
An apparatus (10) for sterilising soil, preferably agricultural soil (13), comprising a sterilising equipment having an apparatus for administering at least a sterilising substance to said soil. The apparatus comprises means (39) for compacting the soil acting on the soil subsequently to the administration of said sterilising substance. According to another aspect, the apparatus comprises means (47) for cleaning the surface of the soil, acting on the soil before said means for administering the sterilising substance to the soil.
Claims70
Apparatus (10) for sterilising soil, preferably an agricultural soil (13a), comprising a sterilising equipment having at least a first sterilisation apparatus comprising means for administering a sterilising substance (11a) to said soil, characterised in that it comprises means (39) for compacting the soil, acting on the soil subsequently to the administration of said sterilising substance.
An apparatus as claimed in any of the previous claims, characterised in that it comprises mulching means (41, 45) able to lay a mulching sheet (P) on the compacted soil.
An apparatus as claimed in any of the previous claims, characterised in that said first sterilising apparatus comprises means (28) for heating said sterilising substance, preferably in the form of a boiler for heating said first substance (11a).
An apparatus as claimed in any of the previous claims, characterised in that it comprises means (37) able to break up the soil, which are supported between said means (38) for administering the second reactant to the soil and said means (36) for administering the first reactant to said oil.
An apparatus as claimed in any of the previous claims, characterised in that said means (37) able to break up the soil remove said soil substantially to the depth reached by said means (36) for administering the first substance.
An apparatus as claimed in any of the previous claims, characterised in that the tank (30, 30′″) for said first substance is supported in correspondence with the front part (14) of the apparatus.
An apparatus as claimed in any of the previous claims, characterised in that said tank (30′) for the first substance is positioned between said means for heating the first substance (28) and the rear part (16) of said apparatus.
An apparatus as claimed in any of the previous claims, characterised in that said tank (30″) for said first substance is supported in correspondence with the flank (18) of said apparatus.
An apparatus as claimed in any of the previous claims, characterised in that it comprises means (W1, W2, D1, D2, G1) for adjusting the depth of insertion into the soil of said means (36) for transferring the first substance (11a).
An apparatus as claimed in any of the previous claims, characterised in that the means (235a) for supporting the components of the second sterilising apparatus are supported below the means (34a) for supporting the components of the first sterlising apparatus.
An apparatus as claimed in any of the previous claims, characterised in that the boiler (428) for heating the first substance has a boiler body (428′) of substantially cylindrical shape, in which the water to be heated passes, which has a longitudinal axis (L) that extends, in substantially horizontal direction, longitudinally to the apparatus.
An apparatus as claimed in any of the previous claims, characterised in that the auxiliary sterilising equipment comprises a main supporting frame (4T1) and a secondary frame (4T2) which sustains at least said means for transferring the sterilising substances (436, 438) and which can be moved transversely to the first frame (4T1).
An apparatus as claimed in any of the previous claims from 11 through 59, characterised in that, in said bar for transferring the first substance to the soil, such an arrangement of the holes is provided as to allow the jets of steam angularly directed according to one of the angular directions ranging substantially between 30° and 180°, preferably between 45° and 180°, and yet more preferably between 60° and 180°, starting from the vertical direction (V).
An apparatus as claimed in any of the previous claims, characterised in that the pressure of the steam exiting the vaporisation means varies from 5 to 12 bar and is preferably equal to 9 bar.
An apparatus for administering a reactant able to provide an exothermic reaction as claimed in any of the previous claims.
Organ (36, 136, 436) for transferring at least a substance into the soil as claimed in any of the previous claims.
A method for sterilising soil, preferably agricultural soil (13), in which a sterilising substance (11a) is administered to said soil, characterised in that it comprises a soil compacting stage, executed on the soil subsequently to the administration of said sterilising substance.
A method for sterilising soil, preferably agricultural soil (13), characterised in that it comprises a stage of superficial cleaning of the soil.
A method for sterilising soil, preferably agricultural soil (13), characterised in that it comprises, after the application of at least a sterilising substance to the soil, the application, on the surface of the soil, of a layer of a substance that reacts exothermically with said first substance.
