Description

The invention relates to a cable plow for introducing one or more lines, in particular cables or pipes, into the ground.

The cable plow according to the invention comprises a sword suitable for engaging the ground to form a gutter and a laying shaft for inserting one or more cables into the gutter formed or can be formed by the sword, the laying shaft being arranged behind the sword in an intended travel direction.

The gutter formed by means of the sword must be backfilled after the line or lines have been introduced. The soil or soil material on the side of the earth gutter serves as filling material. However, there is the disadvantage that the soil or the soil material is often present in very large fragments, so that cavities form around the line or lines during filling. It is important to avoid these cavities because the lines, for example power lines or water lines, can cause heat build-up in the cavities, which in turn has a negative effect on the lines.

It is therefore the object of the invention to provide a new cable plow, in particular a cable plow, with which the aforementioned disadvantages are at least largely avoided.

This object is achieved by the features of claim 1. Advantageous refinements and developments are specified in the dependent claims.
The cable plow according to the invention is characterized in that two or more pre-cutting knives are arranged on the cable plow for cutting the soil, in particular to the side of the earth gutter.

A major advantage of the invention is that when the cable plow is moved through the ground, the pre-cutting blades cut the soil to the side of the gutter in order to loosen the soil and / or to comminute the soil in such a way that filling material is formed for the gutter, which after can be used to plow in the pipe or pipes to fill the gutter. The main advantage of ground as a filling material that has been crushed in this way is that, after the ground channel has been filled, cavities or large cavities around the lines are at least largely avoided. Such cavities are disadvantageous in the case of lines that heat up, since they impede heat dissipation

According to a particularly preferred embodiment of the invention, it is provided that the precutting knives are vertical precutting knives and / or horizontal precutting knives. It can also be provided that a number of the precutting knives are vertical precutting knives and / or a number of the precutting knives are horizontal precutting knives.

In particular, the term “vertical and / or horizontal” is to be understood in relation to the ground surface. “Vertical and / or horizontal” should preferably be understood as “essentially vertical and / or horizontal”, with “essentially” meaning a deviation of up to 45 °, preferably up to 30 °, from the floor surface.

At least a number of the pre-cutting knives are preferably arranged, in particular laterally, on the sword and / or on the laying shaft. Alternatively or additionally, it can be provided that at least a number of the precutting knives are arranged, in particular laterally, in the area of the sword and / or in the area of the laying shaft.

According to one embodiment of the invention, the cable plow has one or more connecting means, in particular articulated arms or connecting rods, for connecting the sword and the laying shaft, the or a number of the pre-cutting knives being arranged on the connecting means or means.

It can be provided that at least two wings are arranged laterally on the sword and / or on the laying shaft and / or on the connection means (s), the wings being designed or arranged in particular perpendicular to the sword and / or laying shaft, the or a number of Precutting knives are arranged on the wings.

Preferably, one wing can be provided on each side of the sword and / or the installation shaft and / or the connecting means. It can also be provided that the wings themselves form pre-cutting blades.

It can be provided that vertical precutting knives are arranged on the lateral wings, the vertical precutting knives protruding downwards and / or upwards from the wings.

Furthermore, it can be provided that the vertical precutting knives are arranged offset from one another at least in sections and / or at least in sections next to one another and / or offset outwards on the wings against the intended direction of travel.

According to a further development of the invention it is provided that the vertical precutting knives are inclined towards the sword and / or the laying shaft, or are inclined away from the sword and / or the laying shaft. It can also be provided that the vertical precutting knives are inclined forwards or backwards in the intended direction of travel.

Horizontal precutting knives are preferably arranged on the sword and / or on the laying shaft and / or on or on the connecting means.

Several horizontal precutting knives can be provided, at least in sections one above the other and / or in sections offset against the intended travel direction and / or offset against the intended travel direction backwards and / or forwards or above and / or below.

It can be provided that the horizontal precutting knives are inclined upwards or downwards in relation to the ground surface.

It is particularly preferred that the precutting knives each have or form a cutting edge, the cutting edge being arranged or formed at the front of the precutting knives in the intended travel direction.

The precutting knives can be designed like blades or flat or tooth-like or claw-like. For example, the pre-cutting blades are made of steel.
