Abstract
A soil treatment apparatus (10) comprises an endless band (12) of resilient material with soil treatment teeth (14) projecting radially therefrom. The teeth are replacably attached to the band (12).
Claims26
A soil treatment apparatus comprising an endless band of resilient material and a soil treatment component releasably attached to the endless band so as to project radially therefrom.
A soil treatment apparatus according to any preceding claim, in which the soil treatment component is relatively hard and the endless band is relatively pliable compared to each other.
A soil treatment apparatus according to any preceding claim, in which the wall thickness of the endless band is less than the wall thickness of the soil treatment component.
A soil treatment apparatus according to any preceding claim, in which a plurality of radial apertures is formed through the band and a respective plurality of soil treatment components is provided.
A soil treatment apparatus according to any preceding claim, in which the soil treatment component has a mounting part and a soil treatment part.
A soil treatment apparatus according to any preceding claim, in which the soil treatment component is formed in two separate parts, the first part being arranged radially outbound of the endless band and the second part being arranged radially inbound of the endless band, the first part for treating the soil and the second part for securing the first part on the band.
A soil treatment apparatus according to any preceding claim in which the apparatus is carried on a cylindrical core.
A soil treatment apparatus according to any preceding claim, in which the soil treatment portion of the apparatus is either pyramidal, frustopyramidal, conical or frustoconical.
A soil treatment apparatus according to any preceding claim, in which the soil treatment component is formed from rubber or other suitable elastomeric material, preferably recycled rubber, most preferably rubber from recycled vehicle tyres.
A soil treatment component having a soil treatment portion and a base portion, the base portion having a peripheral edge which projects from the middle part of the base portion, whereby a clearance is formed between the middle part of the base portion and a surface on which the soil treatment component rests due to the projection of the peripheral edge.
A soil treatment component having a body of moulded material and one or both of a load spreading member and a fastener, moulded therewithin.
A soil treatment component formed from rubber from recycled vehicle tyres.
A method of making a soil treatment apparatus comprising the steps of providing a vehicle tyre, removing the tread of the tyre and forming apertures through the radial wall of the tyre.
A method of making a soil treatment apparatus, in which the step of removing the tread may comprise grinding or cutting the tread away from the tyre.
A method of making a soil treatment apparatus, in which the tread material ground or cut away may be used to mould the aforesaid soil treatment components.
