Description

This invention relates to a Trenchless Ducting / Cable / Tube Laying Machine designed for laying ducts in the ground without digging out backfilling the trench after the laying cables / tubes / trenches or is completed.

The complete machine consists of the following sub assemblies Figure Figure Figure Figure Figure Figure Figure Figure Figure Figure Figure Figure Figure With number filled and is is is is is is is is is is is is is are illustrated on the accompanying drawings, a front elevation of the complete machine, plan of the complete machine. section through the complete machine, front elevation of the chassis only, plan view of the chassis only cross section through the chassis only, side elevation of the vibrating plough, front elevation of the vibrating plough, plan view of the vibrating plough, side elevation of the slitting disc, front elevation of the slitting disc, side elevation of the support wheel assembly, front elevation of the support wheel assembly. chassis consists of section steel tubes end with steel a reference to Figure 4, 5, 6 the of square or rectangular hollow with concrete 2 and capped each containing holes for attaching the plough unit or plates 3 the support wheels unit and the slitting disc unit to this chassis. Two flanges the chassis with pin adjustable link of a system.

Four flanges 6 are located at a the bottom of the chassis to accept are located around the centre line of holes 5 for fitting the top or normal tractor three point linkage suitable location near the fixed links of a -2normal tractor three point linkage system.

Two flanges 7 are located about the centreline to take the slitting disc unit when required to operate the cable laying etc. on the centre of the machine.

Two flanges 8 are located about the centre line at the back of the chassis to take the plough unit when required to trench on the centre of the chassis. r With reference to Figure 7, 8, 9 the plough consists of a steel cutting plate 9 with tapered adges 10 and faced with hard wearing welded cutting edge 11. A steel feeder tube 12 is attached tc the blunt edge of the cutting plate. This tube is manufactured in two halves cut along the length of the tube to facilitate removing the machine from the tube or cable been laid.

Mounted at the top of the feed tube is a tractor driven hydrolic or electric motor 13 which is used to cause the plough assembly to vibrate during laying.

With reference to Figures 10, 11 the slitting disc unit consists of a steel cutting disc 15 mounted on a spindle 16 fitted between the forks 17 of the unit. The forks are welded together and have pin holes 18 for fitting the unit to the chassis in each of the three locations (left hand side, right hand side and middle of chassis). A lifting handle 19 is attached to the top.

With reference to Figure 12, 13 the support wheel assembly consists of three wheels 20 fitted on a channel frame 21 by means of an axel 22.

The channel frame 23 is attached to the adjustable leg of a screw jack 24 which has a steel plate 25 with two holes 26 for fitting to chassis unit using removable pins 27.

Claims

CLAIMS What we claim is: 1) A machine for directly laying cables, ducts & pipes into the ground consisting of a chassis which can be mounted 5 directly to normal three point linkage systems of agricultural tractors . Mounted on this chassis is a vibrating plough unit with a feeding tube attached to allow the direct injection of the cable, duct or pipe to the bottom of the trench 10 while the trench is been cut at a ground speed of up to 1 km per hour without requiring backfilling of the trench and causing the minimum of disturbance to the ground in the area. 2. ) A machine according to claim 1) characterized in that 15 the vibrating plough, slitting disc and support wheels can be attached to the chassis in a position to lay the cable, duct or pipe on the left hand side, the right hand side ot the centre of the chassis. 3. ) A machine according to claim 1) and 2) with the feed 20 tube manufactured in 2 halves allowing the plough to be disengaged before coming to the end of the tube or cable and re-engaged further along the tube or cable as necessary or to facilitate removal of the machine at the end of a working shift before reaching the end of the 25. cable etc.
