FR2654578A1 - Vibrating stalk puller - Google Patents

Abstract

Machine for pulling up plants with stalks in nurseries for young trees. The invention relates to a method for making it possible to pull up, without human effort and without mechanical effort of the tractor, the stalks which may reach up to 5 metres high and 0.8 metres deep. It consists of a mechanical eccentric (2/4 - C) which gives the ploughshare oscillation in all directions and eliminates the resistance of the ground. The ploughshare element is telescopic which allows a road-going position which does not extend beyond the gauge (track) of the tractor. In the working position it allows setting as required on the plants. Machine coupled up to the rear of the tractor using the conventional "three-point" system. This machine is particularly intended for pulling up the "stalks" in nurseries for young trees.

Description

 The present invention relates to a POuF machine plucking the rows of shrubs in nurseries, called "stems uar professionals.

 The traditional uprooting, with the mawn, being exceeded, it was tried harvesters by winch but this Drocédé requires many maneuvers, other methods were not more conclusive. Pulling up by tractor is by far the fastest, advantageous and economical, however pulling up, necessarily on the side, makes driving the tractor almost impossible with the downside caused; hence the need to overcome this big difficulty.

 The system according to the invention overcomes this drawback, according to a first characteristic it allows to give the ploughshare, which is in fact the centerpiece of the work, in addition to a vibration an oscillation in all directions. This oscillating vibration shakes the ground and considerably attenuates its resistance (for example puncture machines), and as a result, the driver remains in control of his machine, it shows an important advantage.

 The system according to the invention comprises, in fact, a second characteristic, a shaker. This shaker is necessary to completely clear the plants from the ground and rid them of the soil to put the Dropres roots for marketing.

 The system according to the invention comprises, in fact, a third characteristic, a telescopic system. This telescopic system allows the ploughshare and its assembly to be removed as desired for adjustment, in the working position on the row, or in the transport position and therefore having a dimension not exceeding the track of the tractor.

 Depending on the machine design - the machine is hitched to the rear of the tractor; - the movement is actuated by the PTO like a conventional tool.

- a mechanical eccentric gives the ploughshare in all directions.

- a shaker to free the plants from the ground and lay bare roots.

- a telescopic system which allows to adjust the share in the working position or in the transport position.

The accompanying drawings illustrate the invention
Figures 1 - 2 - 3 - 4 show the usage diagrams.

Figure 5 shows in section, top view, the entire machine.

Figure 6 shows in section, front view, the whole machine has with plowshare and shaker in profile.

 Figure 7 shows in section the transmission of the eccentric system Figure 8 shows the eccentric system.

 With reference to these drawings, our harvester has the advantage of being hitched behind a tractor (1) by the classic 3-point system, it allows the uprooting of shrubs that can reach heights of more than 5 meters and up to 0, 80 meters deep while leaving normal tractor driving.

 The machine frame consists of 3 double tube side members (2-3-4). These tubes fitting one inside the other make it possible to vary the width of the size of the machine, share share and share (5) taken out. The side members (2-3-4) are coupled to 2 flanges (6-7), a princpå; lëV; (6) and a second (7) which suppotrôt the gusset (8) spur holder (9). The assembled parts form the frame and are added the conventional coupling parts (10).

 The oscillation of the coulter (5) is done mechanically by the PTO of the tractor coupled by 1'intermédip% of a cardan transmission (11) to an angle gearbox (12) fixed on the main spar (3 ) of the frame which makes rotation follow a crankshaft (13) supported by a plummer block bearing (14) fixed on the spar (3) and an applied bearing (15) itself fixed on the main flange (6 ).

The eccentric part of the shaft (16) forming the crankshaft is retracted into a long connecting rod end bearing (17) which, fitted into the slide (18), applies its movement to it (desired goal). On the slide (18), acting as a connecting rod, is fixed the share (5), these latter are assembled by bolts. This assembly, slide (18) and ploughshare (5), furnished with anti-friction lardons, making the principle of a connecting rod slides and oscillates on rollers (19) (or other version, on studs, see in use) in the main flange (6).

 The oscillation of the ploughshare (5), 12 mm vertically and 25 mm horizontally, therefore gives a significant striking stroke in the working part, to the bottom of the worked ground where the effort demand is greatest.

fait rentrer ou sortir les longerons

le vérin étant fixé d'un côté et de l'autre de ceux-ci(t 4). En l'occurrence, en position sortie, le soc (5) peut être réglé à son gré sur le plant. En position rentrée, il permet le passage en "enjambeur" entre les roues du tracteur podr l'arrachage des petites tiges. Toujours en position rentrée, le soc (5) permet d'être réglementaire pour le transport puisque, ainsi, l'arracheu se ne dépasse pas la voie du tracteur (1). The telescopic system, thanks to a double-acting hydraulic cylinder (20) and aui is served. On the hydraulic circuit of the tractor,

brings the side rails in or out

the jack being fixed on one side and the other of these (t 4). In this case, in the extended position, the share (5) can be adjusted as desired on the plant. In the retracted position, it allows the passage in "straddle" between the tractor wheels podr the uprooting of small stems. Still in the retracted position, the ploughshare (5) makes it possible to be regulated for transport since, thus, the harvester does not exceed the track of the tractor (1).

 A shaking system removes the roots from the earth. At the end of the shaft (13), on the main flange side (6), is fixed a plate (21) on which pivots a connecting rod (22), this behind transmits a threshing movement to the shaker (23) the latter being fixed plowshare (5).

 The ploughshare (5) cuts the earth by tilting and using the shaker (23) releases the plant by lifting it like a plow mouldboard.

 Alternatively, in difficult cases, an adjustable spur (9), similar to a chisel tooth, is folded on the side opposite the ploughshare (5) in order to balance the draw.

 The machine according to the invention is particularly intended for nurserymen for uprooting "stems" intended for marketing.
