​Making easier the​ ​vineyard​ ​pre​pruning tasks​


​As we commented in ​an old post, we would like to publish more post​s​ about vineyard jobs than we published ​in previous years... ​A​t this time, we are going to speak about prepruning tasks ​which are carried out after ​wine ​vintage when the vineyard don't have leaves​ and ​just before ​performing ​manual pruning tasks.

​A​ few weeks ago​ we visited our cousin Victor​ in the El Provencio Village (it is really winegrower Village) and we could see the "General Agrícola" prepruner machinery working. Victor was working in his vineyard with Daniel (he is ​the ​prepruner machinery​ owner​). It was the first time we saw this machinery work​ing​, so ​we were impressed, we really liked ​it ​so much.

The goal, we can get with this jobs, is to take out the end part of the vine shoot that are entangled in the wires. On this way, the ​later ​manual pruning task ​i​s really easy. This prepruner machine is ​composed of ten cutting discs that the driver can set in different heights to cut the vine shoot. As you can see in our video, the driver has to open and close the prepruner always the machine is near ​each ​stake... it ​seems to be a very complex ​job ​but he has a special electro-hydraulic system that makes him this job very easy​, reaching a working speed of 8 km/h​​.​​

As also you can see in our video, this prepruner machinery is installed on a grape harvester (it is a Gregoire G107... as Daniel told us, it is pretty old but it continues working very fine), but this prepruner machinery is very ​common to see it on narrow tractors​ since ​all farmers don't have a grape harvester to fix it.​​, this is a special case.

    Hola

    Me podríais explicar con un poco más de detalle el sistema electro-hidráulico de apertura y cierre?? creo que está bastante perfeccionado.

    Gracias.

    Saludos para los seguidores del blog.

    1. Hola.

      Como podéis ver en el vídeo, el conductor de la vendimiadora tiene un pulsador (botón rojo tipo seta) que dispara una electro-válvula para abrir la prepodadora mediante un cilindro hidráulico. De forma automática se cierra pasado un segundo (eso lo pueden regular), por lo que el conductor solo tiene que hacer una pulsación en el botón en cada uno de los postes.

      Tal vez se podría hacer una mejora para que la máquina detectase el poster de forma automática (tal vez como se hace en un arado intercepas) y así el conductor no tener que ir dando al botón... cuando lleva muchas horas de trabajo resulta algo fatigante.
