<p>The present invention relates to an extraction machine connection rod built-in reciprocating-impact extraction portion, including a container body, a dynamic-force driver, a guide, a guide-member connector, a source of impact dynamic-force, and an impact head; the impact head comprises an impact-tooth seat and impact teeth; the guide-member connector is provided in the container body; the guide-member connector includes a guide-rod connection member; the guide-rod connection member is connected, within the container body, with a guide-rod A and with a guide-rod B; guide-rod A, guide-rod B, the guide-rod connection member and the impact-tooth seat form an impact frame; the dynamic-force driver, by driving the guide-rod connection member, brings to reciprocating motion the impact frame which is supported by a guide-body A and/or a guide-body B, and the reciprocating impact of the impact head is brought to motion, thus avoiding a direct connection between a dynamic-force impact member and the impact head, avoiding the problem of a hole-gap, formed between the container body and the end of the dynamic-force impact member which, extending out of the container body, engages in reciprocating motion, being difficult to seal, eliminates the need for a protective cover to be provided for the end of the dynamic-force impact member which, extending out of the container body, engages in reciprocating motion, and ensures improved lubrication and protection for the dynamic-force driver, etc.</p> |
