Abstract

A back-hoe type digger has a parallel arrangement comprising arm A operated by ram A1 and link B having a ram B1 pivoted to a machine body and moving bucket arm D by ram C1 and pivoted link arm C. The digger can be full size or designed for use in allotments or provided on an armoured bomb disposal vehicle. The bomb disposal vehicle can have CCTV, monitors in a turret, claw for tearing the ground up and bomb sensing and exploding equipment.

Description

2350830 PANTOGRAPHIC ACTION FOR BACK ACTORS AND MECHANICAL DIGGERS Back
actors and mechanical diggers work mostly with two jibs which both produce semi circular movement. These contradictory movements have to be combined via the skill of the operator to try and get something akin to linear action.
As the machine is well nigh impossible to control properly, the training of skilled operators is difficult and expensive. The very good operators are few and far between.
My proposal is to simplify the machine by giving it natural linear action to control the bucket.
This would make skilled operators easier to instruct, increasing the number and quality of the top operators available to the contractors.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing.- Referring to the drawing, the pantographic action is produced by mounting two parallel arms from the base A and B working in tandem to control the top arm C which can then be moved forwards and backwards in any pre selected plane (pantographic), From C, arm D descends to base level, with the bucket attached.
These arms are controlled by the hydraulic rams Al, B1, C1, and D1 - by moving ram Al this moves A and B together giving us pantographic action at the bucket. To get level or gradient cuts all the operator has to do is combine two complimentary movements on ram Al and B1 to get a very even linear movement.
The jibs can be set for level cutting of foundations, elevated to any pre arranged angle to allow grading from the bottom of an embankment, or the system can be set on a downward angle to grade an embankment from the top.
This system could have gradient meters mounted on the bucket arm D so that the operator could work to very precise instructions.
A pantographic action which when applied to back actors and mechanical diggers produces a natural linear action to control the bucket and make excavation work easier and more accurate.
I envisage that this machine could be produced in three very distinct sizes.
There could be a small version for working in gardens and allotments, allowing all the soil cultivation etc. to be done from the paths, eliminating at a stroke the problems of surface compaction and damage to the drainage systems.
There could be a normal sized machine for building site work.
Finally, there could be a very large machine with extensive jibs for mine clearing work in the aftermath of war. For this very dangerous work, it would have to be mounted on a large armour plated military type vehicle and fitted with C.C.T.V. so that the operator could work in safety from within a control turret equipped with monitors. The end of this very long jib would have a large claw to tear up the terrain and in addition would have equipernent for sensing and exploding these very dangerous ordinance which while designed to maim and kill professional soldiers. After the war, it is left on the battlefield, where it can injure and slaughter innocent adults and children, who work the land to ward off starvation.
