FR3084811A1 - DEVICE FOR HANDLING FILLED BOOTS LINKED WITH A NET, CUTTING THE NET AND SEPARATING THE CUT NET WITHOUT MANUAL INTERVENTION - Google Patents

Abstract

The invention relates to a cage (1) opened by the bottom adaptable to the front of a loader or a telescopic with two flaps (2) animated around a rotation axis (3) with a jack (4) by component. The two components are combined on the same hydraulic function. The locking is partial, allowing the cage to pass over a knife (5). In addition, the cage is equipped with a system of claws (6) for retaining the net of the round boots. The latter is driven by a hydraulic cylinder (7). The claws describe a rotation of 90 degrees around the axis (8). The device according to the invention is particularly intended for handling round bales of fodder, for cutting the net, for retaining it in the cage and for extracting it without manual intervention in order to fill the straw spreader.

Description

The present invention relates to a device allowing the separation of the net which binds the round bundles of fodder and its extraction without manual intervention in order to feed the straw blower or any other material used for the distribution of fodder. In this case, with the device, the breeder descends the cage (open flaps) onto the round boot, closes the flaps. Then he passes the cage with the boot inside on a knife installed on a sheet placed on the ground. The net is then cut, it remains to be placed above the straw blower, to grab the net hydraulically and open the flaps. The fodder descends into the straw blower, the net is retained. It remains to release the net in a suitable place.

Cutting the fillet is traditionally done by hand. To put a bale of fodder (about 300kg) in the straw blower, the breeder, at the wheel of his tractor equipped with a loader, manipulates a bale of fodder, places it above the straw blower, gets off the tractor, cuts the net under the boot with a knife, fold up the two sides of the net, hang them on the loader, go back up in the tractor, lower the boot into the straw blower. Then it collects the net to manually separate it from the feeder. In addition, it should be noted that the forage boots are more or less stable, whether they are short or long strands.

When the strands are short, the forage spreads in a haphazard manner as soon as the net is cut. It is a tedious workstation, source of many musculoskeletal disorders (getting on / off repeatedly from the tractor, access to the straw spreader not suitable for cutting the net, etc.).

The device according to the invention overcomes this set of drawbacks described above. According to a first characteristic, it has a metal case (this case adapts to the charger) opened by the bottom which can (this case adapts to the charger) opened by the bottom which can contain a round boot. The box partially closes at the bottom with two hydraulic flaps, there remains a free space allowing the box to pass over a knife fixed on a sheet metal on the ground.

The device has a second feature for gripping the net. This device consists of four side claws (two on the right and two on the left) pivoting 90 degrees around two axes crossing the main chassis of the body. The side claws are driven by a hydraulic cylinder.

According to particular embodiments:

- The claws are adjustable in length to adapt to the different diameters of round boots.

- Claws can be added to the device.

The accompanying drawings illustrate the invention.

- [Fig.l] represents the closed box seen from the front. [Fig.2] represents the open box seen from the front.

- [Fig.3] represents the body seen from the side.

- [Fig.4] represents the open claws.

- [Fig.5] represents the closed claws.

- [Fig.6] represents the knife.

With reference to these drawings, the device comprises a box (1) made of square tubes 50mm side and 3mm thick mechanically welded.

The hydraulically driven flaps (2) (4) (Fig. 3) are made of square tubes 50mm side and 3mm thick mechanically welded.

In the embodiment according to Figure (2), the flaps partially close the body from below, pivot about an axis (3).

The device comprises a system of claws (6) (Fig. 3) 65 which pivots around two axes of rotation of 20mm in diameter (8) over an amplitude of 90 degrees.

The 20mm diameter axes of rotation pass through the frame (1).

According to a variant not illustrated, the claws are 70 adjustable in length to adapt to the different diameter of the forage boots.

The device according to the invention is particularly intended for handling round bales of fodder, cutting the spinning, retaining it in the cage and extracting it without manual intervention.
