Abstract
A diamond drill bit with a trapezoid matrix comprises a steel body and a matrix formed on the steel body. The top end of the steel body is composed of a plurality of steel body end portions. Each steel body end portion is composed of a steel body top surface, a steel body inclined side and a steel body straight side. The matrix is composed of matrix blocks wrapped at the end portions of the steel body. Each matrix block is composed of a matrix block top portion corresponding to the steel body top surface, a matrix block inclined lateral portion corresponding to the steel body inclined side and a matrix block straight lateral portion corresponding to the steel body straight side. The contact area between a matrix block lip face and a rock when the diamond drill bit performs drilling, pressure exerted by a drill bit lip portion in unit area on the rock is large, thereby enabling the diamond on the matrix block lip face to effectively break the rock, increasing drilling speed and resolving the problem that the drilling speed is low in integral competent formation. Simultaneously, when the top portions of the matrix blocks are abraded, the abrasion of the end portions of the steel body is faster than that of the matrix block inclined lateral portion and the matrix block straight lateral portion. Only the matrix block inclined lateral portion and the matrix block straight lateral portion can be contacted with the rock, the contact area between the matrix and the rock surface is not increased greatly, thereby guaranteeing drilling efficiency of the diamond drill bit.
