Rotary hydraulic log grapple based on excavator
The invention relates to the technical field of log grapplers, and discloses a rotary hydraulic log grappler based on an excavator, the rotary hydraulic log grappler comprises a rotary table, a driving claw and a driven claw, and a sliding cavity is formed in the driving claw. By designing the sliding cavity, the sliding claw, the buffer cavity, the hydraulic cavity, a rubber block, an ejector rod and a piston plate, wood located on the upper side of the log grapple acts on the rubber block, and the ejector rod drives the piston plate to move through movement of the rubber block, so that hydraulic oil in the hydraulic cavity gradually enters the buffer cavity and the sliding cavity, and the sliding claw extends out of the sliding cavity; according to the log grapple, the sliding claws are prevented from making direct contact with the side face of lower-layer wood to cause wood damage when the log grapple grabs the wood, through the design of the buffer cavities and the through holes, the damping effect is generated on backflow of hydraulic oil, stable clamping of the wood after the sliding claws slide out can be promoted, and meanwhile due to the fact that the sliding claws do not slide out when the wood is clamped, the wood can be clamped stably. And the opening of the log grabber for clamping the wood is in the maximum state, so that more or thicker wood can be conveniently clamped.
本发明涉及抓木器技术领域，且公开了一种基于挖机的回转液压式抓木器，包括旋转台、主动爪和从动爪，所述主动爪的内部开设有滑腔。本发明通过设计滑腔、滑爪、缓冲腔、液压腔、橡胶块、顶杆和活塞板，通过位于抓木器上侧的木料作用在橡胶块上，利用橡胶块的移动使顶杆带动活塞板移动促使液压腔内部的液压油逐渐进入缓冲腔和滑腔内部并使滑爪伸出滑腔，使得抓木器在抓举木料时，避免滑爪直接接触在下层木料的侧面上造成木料损伤，且通过缓冲腔和通孔的设计，对液压油回流产生阻尼的效果，可促进滑爪滑出后对木材的稳定夹持，同时由于在对木料进行夹持时滑爪还未滑出，使得抓木器对木材夹持的开口处于最大状态，便于夹持更多或者更粗的木料。
