Connecting lock block for micro-deformation reamer

Abstract

The invention relates to the field of dredging ship reamer fixing devices, in particular to a connecting lock block for a micro-deformation reamer. The connecting lock block for the micro-deformationreamer comprises a metal strip, wherein a lug boss used for embedding with a tool holder is arranged in a rear end surface of the metal strip along a vertical direction; a groove is formed in one sideend part perpendicular to the end surface, on which the lug boss is formed, on the metal strip; embedded grooves are formed in end surfaces on the same side of oppositely arranged upper end part andlower end part of the groove; the upper end part and the lower end part of a movable metal strip are embedded into the two embedded grooves; a vulcanized rubber strip is jointly arranged between the end surfaces on the same side of the movable metal strip and the groove formed in the metal strip; two side end parts of the vulcanized rubber strip are fixedly installed with an inner side end surfaceof the movable metal strip and an inner side end surface of the groove formed in the metal strip; the width between the two side end parts of the vulcanized rubber strip adapts to a distance betweenend surfaces on the same side of the movable metal strip and the groove formed in the metal strip; and an end surface, far away from the groove formed in the metal strip, of the movable metal strip contacts the embedded grooves formed in the metal strip.

Description

technical field [0001] The invention relates to the field of fixing devices for the reamer of a dredging ship, in particular to a connection lock block for a micro-deformation reamer. Background technique [0002] With the acceleration of my country's infrastructure construction, a large amount of sand, cement and other auxiliary materials are needed. Sand dredgers are a common special equipment for mining and excavating sand. [0003] Different types of reamers are installed in the sand dredger to mine different types of sand and gravel. The existing connection device of the reamer generally includes a connecting block similar to a pin to fix the reamer and the knife holder. . The existing connecting blocks are generally made of cast iron or other metal materials, but there are certain deficiencies in the use of such connecting blocks. The connection block made of metal material will be in contact with water and other media, so it often rusts during use, and the rusted co...
