DESCRIPTION:
BRIEF SUMMARY
This invention relates to an apparatus for pressing netting to support turf and the like into the ground surface and is also applicable to the location of small net elements in the ground surface and also the laying of stolons into the soil surface.
Turf netting may be laid on the ground surface where turf is to be sown so as to stabilise the surface and prevent the movement of the top soil by wind and the like and, normally, to locate such netting, it is necessary to remove the netting from a roll and to peg it or otherwise physically connect it to the surface to prevent movement thereof.
This arrangement, whilst quite satisfactory practically, is nevertheless labour intensive and thus time consuming and costly.
It is also desirable when stolons are to be planted that these be located into the soil surface and, again, this is a labour intensive, time consuming and a somewhat difficult procedure.
Also there are applications when small mesh elements such as those sold as Netlon (registered trade mark) mesh elements are to be located in a surface, such as a sand surface.
These elements are normally located before the laying of sod, particularly washed sod, to provide a consolidated surface onto which the sod grows.
This is particularly useful in such areas as, say, racecourses and the like where the turf, when established, is likely to be cut and moved by horses' hooves.
It is the object of the present invention to provide an apparatus which will locate netting an other materials automatically and accurately.
The invention, in its broadest sense, provides an apparatus to insert netting or other articles into the ground surface which includes a frame adapted to be connected to a prime mover and having a roller transverse to the direction of normal movement of the frame, the roller having spaced annular extensions thereabout, the roller limiting the depth of entry into the ground of the extensions to the radius of the annulus formed by the extensions, and vibration means associated with the roller which caused the roller to vibrate, the extensions being capable of effectively fluidising the ground surface so that the netting or other article fed to the underside of the roller can be located in or under the ground surface by pressure from the discs whilst the ground is fluidised.
In one aspect the invention is used to locate turf netting into the ground surface and the material to be located by the roller is netting in a sheet form which is fed to the underside of the roller.
The frame may be adapted to be connected to the three point linkage of a tractor, and the vibrating means, may be powered from the power take off of the tractor.
The netting tan be delivered from a carrier mounted, either forwardly of the apparatus of the invention, or on the front of the prime mover.
The apparatus is also useful for locating solons on or in the ground surface and again these are fed to the forward side of the roller and, further the apparatus can be used for locating Netlon mesh elements into a prepared surface before the laying of washed turf.
The invention also provides a method of inserting a mesh or the like into the ground surface comprising passing the mesh beneath a roller transverse to the direction of normal movement of a prime mover, the roller having spaced annular extensions thereabout, the roller limiting the depth of entry into the ground of the extensions to the radius of the annulus formed by the extensions, vibrating the roller to cause the extensions to effectively fluidise the ground surface so that material fed beneath the roller is located in or under the ground surface by downward pressure from the discs whilst the ground is fluidised.
In order that the invention may be more readily understood, we shall describe, in relation to the accompanying drawings, one particular embodiment of device made in accordance with the invention.
