Roller press briquetting hydraulic means and roller press briquetting system

The utility model provides a roller press briquetting hydraulic means and roller press briquetting system, include at a distance of primary shaft bearing (1) and secondary shaft bearing (2) that the certain distance set up, and form primary shaft bearing (1) and airtight hydraulic pressure chamber between secondary shaft bearing (2), airtight hydraulic pressure chamber and hydraulic pump (4) intercommunication to drive through the hydraulic pressure that changes airtight hydraulic pressure chamber primary shaft bearing (1) and/or secondary shaft bearing (2) motion for hydraulic means drive through exerting the tightening force simultaneously to the both ends bearing frame to the running roller with material extrusion, component parts that this kind of structure let the bearing frame become hydraulic means has not only solved the narrow and small difficult problem that can't set up one set of conventional hydraulic system in space between the diaxon bearing, can not increase the requirement to bearing frame intensity in addition, simultaneously through with hydraulic pressure direct action on the bearing frame on both sides, avoided not only having reduced manufacturing cost widely because of setting up a large amount of high strength material that big and heavy frame consumed, the frequency of damaging the maintenance in addition is also lower.
