Description

Grape hauling device during Collection in steep vineyards.

Object of the invention

The present invention relates to a device  for hauling the grapes during their harvest in vineyards sheer

Background of the invention

There are currently vineyards on land steep, normally set in terraces of major or minor width and height

An example of these vineyards exists in the called "Ribera Sacra", consisting of steep canyons where the Sil and Miño rivers run. This land, extremely abrupt, difficult and becomes a very task painful and dangerous to carry the grapes to their point of collection located in the planes above the canyon, which means a inconvenience that is remedied by using the device of the invention.

Description of the invention

The device of the invention has a optimal constitution to facilitate the hauling of grapes during collection in steep vineyards, avoiding dangers and efforts to Workers.

According to the invention, the device is constituted by an indescarrilable guided car by guides arranged in a direct downward direction along the Slope of the vineyard. The car incorporates a platform or zone of preferably staggered load to fit the unevenness of the land and be, where appropriate, at the level of several adjacent terraces to facilitate the work of hauling grapes.

The car supported by the guides is in turn suspended, by cables, from a motorized reel located preferably at the head of the guides, running through these upwards by the cable pull and in the direction descending by gravity as the cable develops from the winder

The car has parachute means to stop its free fall by the guides in case of breakage of the cable or cables of suspension, preferably constituted by a coining to the structure of them.

For its part, the winder is preferably of  electric drive, either by mains power supply or from a stand-alone generator.

Brief description of the drawings

Figure 1 shows an overview of the device of the invention installed in an abrupt vineyard set to terraces.

Figure 2 shows a constructive detail of the guides of the device of the invention.

Figure 3 shows a view of the carriage of the device of the invention.

Figure 4 shows another constructive detail of the guides where the cable protection rollers appear in case of inclination of the sections of guides.

Figure 5 shows a detail of the media car parachute of the device of the invention.

Description of a practical embodiment of the invention

The device 1 of the invention comprises parallel guides 2 lying on the ground 3 in direct path and falling.

The guides have a C section, as seen in the Figure 2, to drive lower rollers 4 of a carriage 5. The C-shape of the guides prevents the exit of the sheaves without impossible deformations during operation normal device, thus guiding the car unbreakable.

The parallel arrangement of the guides is maintained  by crossbars 6, preferably of angular section, and their props 7 have cross braces 8 that also cooperate in maintain a perfect parallel between them.

The car comprises a frame 9 from which they emerge inferiorly plates 10 in which the rollers 4 are mounted, and the profiles are welded 11 in square to fix some 12 mesh and 13 respectively determining the bearing surfaces horizontal and lateral for the boxes of grapes.

In the header of the guides is installed detachably a motorized winch 14 whose cable 15, conveniently sized, suspend the car. The engine of winch is preferably driven by a generator transportable and detachable to be able to transport it and Use it in cars located in other guides.

In case of change of inclination between sections of the guides with increasing inclination downwards will rollers 16 are installed at the tilt shift points swivels on which the cable 15 will support and run avoiding friction with fixed parts that could damage it.

Precisely for the case of cable breakage suspension, the car incorporates 17 outgoing arms lower that wedges on the crossbars of the guides, stopping their freefall. These arms 17 emerge from a structure 18 tilting by the action of springs 19.

Cable 15 suspends the car by attaching to another cable 20 proper of this one that goes through pulleys 21 that lead its throw in the right direction to compensate for the throw of the springs 19, arms 17 being collected. In case of cable breakage 15 or 20, the springs 19 swing the structure 18 and the arms 17 come out and lock in any of the crossbars of the guides

Describe sufficiently the nature of the invention, as well as how to perform it in practice, should be noted that the provisions indicated above and represented in the attached drawings are susceptible to modifications of detail as long as they do not alter the principle fundamental.

Claims (6)

1. Device for hauling grapes during harvesting in steep vineyards, which are usually set up on terraces; characterized in that it comprises a carriage supported and guided indescarrillably by guides arranged in direct downward direction along the slope of the vineyard; the car has a stepped loading surface; The car is suspended from at least one cable that can be developed from a transportable motorized reel, and has parachute means in order to prevent its free fall in case of breakage of the suspension cables. 2. Device according to claim 1, characterized in that the indescarrilable guiding of the carriage is carried out by means of the arrangement of two parallel guides that have a C-shaped section, facing or opposite, running through the formed sine between the respective lateral branches some rollers fixed in lower extensions of the car. 3. Device according to claim 2 characterized in that the parallel guides are related by crossbars and fixed to the ground by braced supports, in order to achieve a uniform mutual interdistance. 4. Device according to claim 1 characterized in that at the points between sections of guides where there is an increase in the inclination downwards, rotating rollers supporting the suspension cables are installed. 5. Device according to claims 1 and 3, characterized in that the parachute means of the car consist of a tilting structure by means of recovery springs, the draft of which is compensated by pulling a pulley-guided cable and connected to the suspension cable, emerging from the structure about locking arms on the guide crossbars. 6. Device according to claim 1 characterized in that the transportable motorized reel and the suspension cable are constituted by an electrically operated winch detachably arranged the head of the guides.
