DE102013005586A1 - Weed cutters / planting hole drill - Google Patents

Abstract

The invention relates to a device with the aid of (A) a simplification of the removal of herbs from meadows, lawns, flowerbeds or other areas is achieved, and (B) the planting of planting holes, especially with control of the depth of hole and with subsequent refilling is substantially simplified , The device is stuck non-slip in the ground. The invention is technically based on the already known auger or the already known auger for solids.

Description

According to the device according to (A) is placed on the herb to be removed and the internal milling / conveying mechanism set in rotation until the herb is milled to the required depth. The cut is collected in the upper part of the device so that several cutting operations can be performed without intermediate emptying. This collection area can be emptied through a closable opening.

According to the device according to (B) is placed at the desired location and set the internal milling / conveying mechanism in rotation until the soil is excavated to the required depth. The device penetrates into the soil accordingly. An externally mounted on the device depth stop allows limiting the hole depth to the required level to ensure uniformity of the same over several holes.

After loading the planting hole with seeds, plant bulbs or the like, the borehole can be filled again cleanly with the excavation just picked up by reversing the direction of rotation. A close with other filling material is also possible if the device is previously charged. Excavation / filling material can be taken from the collection area in the upper part of the unit via a closable opening.

The device can be performed either by hand or as part or attachment of a working machine.

In the following the invention will be explained in more detail with reference to the accompanying drawing. It shows 1 an inventive embodiment of the device with left-handed, single-auger and straight, horizontal cutting edge and hand crank.

The device consists of an outer tube ( 1 ), which forms the basic body of the device. At the bottom of the tube ( 1 ) may contain one or more points / claws ( 2 ) be attached to the non-slip setting in the ground. Furthermore, still a handle ( 12 ) be provided for better handling. The assembly to a working machine via suitable adapter.

On the outer tube ( 1 ), a device ( 11 ) to limit the cutting or drilling depth are attached. The device ( 11 ) can along the outer tube ( 1 ) to allow different depth settings.

Outer tube ( 1 ), Tips / claws ( 2 ) and handle ( 12 ) can each be made individually and from different materials such as metals, plastics, etc. as well as one piece and material.

Inside the outer tube ( 1 ) there is a wave ( 3 ). This can be designed as a solid or hollow shaft. At least a single axial and radial bearing ( 4 ), preferably in the upper region of the outer tube ( 1 ), should be provided. In the area below ( 8th ), the radial guidance is preferably carried out by the screw conveyor ( 7 ).

At the top of the wave ( 3 ) are a fixed or removable hand crank ( 5a ) or a fixed or removable adapter piece ( 5b ) for a motor attachment. The adapter piece ( 5b ) serves at the same time the non-positive attachment of the motor attachment.

Down on the wave ( 3 ) there are one or more fixed or interchangeable blades ( 6 ).

The cutting edges ( 6 ) can be used as part of the transport screw above ( 7 ) are formed and mounted on this fixed or replaceable or attached detached from the screw to the shaft.

The cutting edges ( 6 ) can be made differently in shape and material and oriented at different and variable angles to suit different needs: z. B. deep or shallow rooted plants, milling a lawn layer, various substrates etc.

The screw conveyor ( 7 ) for conveying the material to be cut or excavation / filling material can be formed in different lengths and pitch, in different number of trains and as a left or right rotation to various claims such. B. long or short parts of plants, lawns, different types of soil, left / right handed user etc to be adjusted.

The screw conveyor ( 7 ) is at least as long trained ( 8th ) that they fall out of the conveyed material from the outer tube ( 1 ) prevented.

The cutting material or the excavation are in the outer tube ( 1 ) collected in and above the screw ( 9 ). The outer tube has at the top or on the side of a suitably closable opening ( 10 ) for emptying cutting material or excavation or for charging with material for filling previously made holes.
