Abstract

A hollow spade consisting of a handle (1), at one end of which a spade section (9) is arranged, characterized in that the spade section (9) is interchangeable with the handle (1).

Description

The The invention relates to a hollow spade according to the preamble of claim 1.

At manually in the context of planting methods, for example forestry, but also to be operated in agriculture and horticulture Equipment is in addition to the planting of the hollow spade in general known. The former is general for all soils suitable for stony ground, but requires one intensive training, whereas the latter in practical Handling easier designed and for shoot lengths of up to 120 cm is usable.

Known hollow spade (cf., for example "Blow by blow", WILD AND DOG 5/2005 ) are usually made of a wooden handle, which is captive with a spade blade in a firm connection.

In Dependence on the length of the plants to be planted, in particular their root system come hollow spade with different Blade lengths and shapes are used. The latter, for example, brings for forestry, however, the need to an assortment for each case of use Hollow spade in readiness to hold, a circumstance in particular can interfere with work in the field.

It The object of the invention is a hollow spade of the initially described Kind in a simple manner with good manageability in terms of to design its variability in practical use. This problem is solved in such a hollow spade by the features of the characterizing part of claim 1.

essential to the invention is hereafter that between the spade section and the stem one interchangeable connection is established. This means that user side for different applications only different spade sections and not complete hollow spade be kept in readiness. different Use cases may be considering the size of the plants to be treated and their Root system, the soil type or the nature of the plant to be planted Soil, z. B. resulting in rooting. For the Users, e.g. As a forestry is obtained in this way the Advantage of a simplified storage of tools or devices.

The Features of claims 2 to 4 are closer Design of the stem directed. Here, the said bridge to support the driving of the hollow spar in the Soil, however, for digging a loosened earth plug to be used. The traverse offers ergonomic benefits and can be used in particular for rotation of the hollow spar around the stem.

to interchangeable attachment of the hollow spade section is the stem provided according to the features of claim 5 with a mounting plate. This thus forms the link between the spade section and the stem.

The Features of claims 6 and 7 are closer Design of the spade section directed. This consists of a hollow-blade part and a preferably one-piece with this trained attachment section. Especially advantageous can the attachment portion for screwing to the mounting plate be furnished. Others, especially easy to handle, the One skilled in the art connecting systems between the spade section and the stem are also considered.

The Features of claims 8 and 9 are further advantageous Embodiments of the stem directed. This can be fully, that means including web and mounting plate made of metal, z. B. steel, so that a robust, in particular mechanically loadable construction results.

you recognizes from the above statements that with the hollow spade according to the invention the user a very flexible working device available is made, which is characterized by a simple structure and especially suitable for off-road work is.

The Invention is described below with reference to that in the drawings schematically illustrated embodiment closer be explained. Show it:

1 a perspective view of a hollow particle according to the invention;

2 a partial view of the II 1 in a flat representation.

1 shows a hollow spade whose metallic stem with 1 is designated and the at its upper end 2 a perpendicular to this extending traverse 3 wearing. On the free ends of the crossbar are each handles 4 . 5 made of wood or plastic.

At the lower end 6 of the hollow spindle facing the end of the stem 1 is a mounting plate 7 fastened, which in one by the traverse 3 and the stalk 1 extends defined level. Also in this plane, at least approximately parallel to the traverse or perpendicular to the stem 1 extends to the mounting plate 7 arranged bridge 8th ,

The jetty 8th can for example in one piece with the mounting plate 7 be formed, whereas these with the stem 1 can be welded. A welded connection can also be made between the crossbar 3 and the stalk 1 consist.

With 9 is a spade section referred to, consisting of a hollow spade 10 and an integrally formed with this plate-like attachment portion 11 consists. The spade section 9 is over the attachment section 11 with four screws 12 with the mounting plate 7 screwed and thus replaceable with the stem 1 in connection.

The profile of the hollow-core part 10 is of a known type and may have the shape of a rounded towards the bottom circular cylinder or circular cone section.

The use of this hollow particle, for example, is as follows:
It is first introduced a first trick vertically into the soil, the web 8th can serve to support the recovery. Subsequently, a second, the first stitch slightly overlapping stitch is introduced so that a complete Erdpfropf dissolved in the soil and this can be removed, the web 8th to support the digging of the Erdpfropfes can be used and wherein in the hole thus formed a plant is used. The plant is then fixed in position by means of the soil plug re-inserted into the hole.

The specific size and / or shape hollow part 10 If necessary, in a simple manner, in particular for the purpose of adaptation to different sizes of plants to be set and / or condition of the soil by replacement of the spade section 9 to be changed.
