DE19545106A1 - Ground film cover stake for plants - Google Patents

Abstract

The stake's head's (1) diameter is large in relation the stake's shaft's (2) thickness. The head has a U- or V-shaped recess extending to the shaft. The minimum width of the recess exceeds the shaft's width. The shaft has a cross ribbed profile, or a hook (5) or claw to prevent the stake being pulled out of the ground from below the film covering by the force of the wind. The stake is made of plastics, metal or a combination of them. The head and shaft are in line for easy installation in a magazine, and the head has two openings for insertion and automated recovery.

Description

The invention relates to a nail that does so serves, cover films and nonwovens on fields and beds to hold firmly to the ground.

The windproof fastening of film and nonwoven webs on the earth's crumb wins in agriculture as well in horticulture more and more important because seeds and seedlings as well as vegetables, plants and fruits must protect against pests, birds, larvae and. Like. And also be protected against frost damage.  

The foil cover and its secure earth fastening promotes a constant microclimate in the earth's crumb and brings about early harvesting of seasonal fruits and vegetables and prevents crop failures caused by pests. The crop yields are also larger and it can several harvests per year can be achieved.

The cover films that are up to 250 m long and over 10 m wide can be used with sandbags, Stones, piles of earth, car tires etc. on their edges weighed down and thereby held down. It is too occasionally common that wooden pegs as a holding means be driven into the earth through the foil.

However, all of these methods are cumbersome and very time consuming. A rational laying of cover foils therefore require a reusable earth nail, which by means of hand-held device or automatically in the earth can be brought in.

The object of the present invention is therefore also in being a simple, cheap, easy and to create quickly processable earth nail that the different requirements for "foils cover - Agriculture ".  

This earth nail must be easy with auxiliary devices recorded and picked up by hand or by machine can be, which includes that the earth nails in a multiple magazine or the packaging container all aligned in the same direction and row get delivered.

The solution to this problem can be seen from FIGS. 1 to 4 and is set out in the claims.

The new earth nail can either be made of art fabric or metal or from a plastic metal composite construction exist.

The new earth nail also has an oversized head, who put the nailed-over foil on prevents the head. The head becomes light tapered stem, the cruciform ribs, ver with wedge-shaped reinforcements or claws are seen, possesses; it can also turn out differently formed "baffles" attached to the shaft that removing the earth nail from the ground Prevent wind pressure on the film.

The head of the new earth nail has one or two (2 × 180 °) or four (4 × 90 °) U-shaped or light V-shaped recesses.  

These recesses range from the top edge to the connection of the nail shaft to the head. Only this recess makes economical, less space-consuming packaging and storage possible and also allows magazine-like lining up of the earth nails, shaft to shaft layered in a row ( Fig. 4). In addition, the precise alignment of the earth nails is the basic prerequisite for easy and quick processing by means of a hand-held tool or for automatic, if necessary, automatic setting.

The magazine reduces the space required for Trans port and warehouse by more than 50%.

The earth nail described here is therefore the only one possible, profitable construction for the covering foil laying to make it more economical and safer.

Removing the earth nails from the earth's crumb can otherwise by hand using a puller respectively.

The advantages achieved with the invention are especially in the acceleration of the covering foil laying and the good securing of the films against Wind pressure caused by the baffles (pos. 5 and 6).  

The geometric formation of baffles (items 5 and 6) and all other conceivable versions can be adapted to the respective soil conditions, such as. B.
heavy soils (clay)
light soils (sand).

The new earth nails are also immovable, what of stones, sandbags, piles of sand or car tires is not to say.

Further advantages are the easy collection of the Nails, their light weight, reusability and they are also light and space-saving to trans port and store.
