FR2512636A1 - Front mounted tractor attachment for handling timber - has three cutting discs and pair of jack actuated arms to feed crusher discharging into skip - Google Patents

Abstract

The front-mounted tractor attachment is used to recover branches and brushwood arising from timber felling operations etc., and also carries out crushing and self-loading operations. It comprises three cutting discs (13-15) mounted on a sub-frame (3) so as to slide laterally together with two jack (21) actuated clamping arms (11). Two indented rollers (10,12,19,20) driven by hydraulic motors are mounted on each of the arms and are used to feed timber to the crusher, the crushed material then being fed to a skip (22) by a chute. The arms are capable of pivoting about horizontal axles under jack actuation and can be raised in unison during cutting operations.

Description

 The subject of the present invention is an assembly, slash recuperator (example branches), non-exploitable coppice slaughterer (example thorns), crusher, self-loader.

The aim of this invention is to transform wood for multiple uses in a single operation - boards intended for the supply of gasifiers - boards intended for cardboard boxes - boards intended for collective heating - boards intended for distillation (methanol) - boards intended biomass
This invention comprises an apparatus in its front part, that is to say - a chassis and, at its end, three cutting discs (13 - 14 - two clamping arms, actuated by jacks and provided at their end with two cylinders comprising teeth for the introduction of wood into the crusher.

- on the rear part of said shredder, a discharge chute for loading the bucket.

This set can be adapted to an all terrain vehicle.

 According to the invention, the all-terrain tractor vehicle, of the axle and rigid chassis type, is characterized, as far as it is concerned, by three engine axles with independent control.

 To better fix ideas, all axles can be powered, depending on the morphology of the terrain. These, on the road, can be reduced to a single driving axle. Many advantages result from the above arrangements - ease of passage of obstacles such as mounds, tree trunks, ditches, due to the possibility offered by the design of the hydraulic translation.

high power with a small footprint: six-wheel drive, four steering (two front, two rear)
Figure 1 shows an overview, Figure 2 a top view.

The main feature of the invention resides in the following fact
It is simultaneously that the operations take place in the harvest of slash - The first operation consists in placing oneself in front of the slash; this being done, the two folding arms (ref 11 figure 2) ae raterment by means of the jacks (ref 21 figure 2).

If the wood is bad, it is possible to lift all of the propeller rollers (marks 10 - 12 - 19 - 20 figure 2) by means of a jack (mark 25 figure 1) without the platform shape (reference 3 in figure 1) does not move.

- Then the propelling rollers (marks 10 - 12 - 19 - 20 figure2) start and push the wood into the wood chipper (mark 2 figure 1).

- The transformed wood is projected by a motor (reference 6 in figure 1) into the chute (reference 7 in figure 1).

 To orient the trajectory of the wafers, the outlet of the chute is orientable (mark 9 in figure 1) the point of rotation is in mark 8 in figure 1.

- The plates thus directed fill the bucket (item 22 figure2).

 Other characteristics and advantages of the invention - recovering from the forest, non-marketable copses.

This operation is carried out using three circular saws (marks 13 - 14 - 15 figure 2) driven by motors (marks 16 - 17 - 18 figure 2). The trees are pushed by the protection (reference 24 in Figure 2) the rest of the operation is carried out in the same way as for the slash.

- On uneven ground, the advantage of the invention consists in being able to either lower or raise the whole of the platform (mark 3 figurel).

- To avoid deformation of the bristles (marks 13 - 14 - 15 figure 2) on bad ground, an advance on slide is planned on sixty centimeters.

Claims (3)

CLAIMS 1) Collecting slash recuperator (example branches) non-exploitable coppice slaughterer (example thorns), crusher, self-loader, capable of adapting to an all-terrain vehicle, characterized in that it comprises, by an apparatus in its part before that is - chtssis and, at its end, three cutting discs (13 - 14 - 15). - two clamping arms, actuated by jacks and provided at their end with two cylinders comprising teeth for the introduction of wood into the crusher - on the rear part of said crusher, a discharge chute for loading the grab. 20) Device according to claim 1, characterized in that the arms of  clamping are each provided with two toothed rollers at their end,  rollers driven by hydraulic motors.  3) Device according to claim 1, characterized as far as it is concerned,  by the clamping arms fixed on the lowest part by two axes  horizontal, in the highest part, fixed by cylinders per  putting a lift of the set of arms independent of the cut. 40) Device according to claim 1, characterized in that the discs  cutting are made up of circular saws mounted on slides,  allowing lateral movement of all the acies, avoiding  deformation of these on bad ground.  5) Device according to claim 4 characterized in that the glis  sières consist of two trapped and sliding rails on a  Raceway. 60) Device according to claim 1, characterized as far as it is concerned,  by an assembly connected to the vehicle by two jacks forming a parallel  deformable gram.
