Embodiment Construction

[0017] Such as Figure 1 to Figure 3 As shown, a pick type drill bit comprises a drill barrel 10, a fixed disc 11 is fixed on the bottom of the drill barrel 10, a drill disc 12 is fixed on the fixed disc 11, and a fixed drill bit is arranged on the drill disc 12. tooth 13. The drill disc 12 is provided with two fan sections along the circumference of the fixed disc, and one of the circumferential sides of the fan section is provided with a mounting plate, and the installation plate is inclined to the plane of the drill disc. The boards are arranged at intervals of 180 degrees in the circumferential direction on the fixed disk, and the inclination directions are opposite. The fixed drill teeth include several fixed drill bits distributed along the length direction of the installation board. The center of the fixed disk is provided with a central column integrated with the two fan sections, and a fixed drill bit is provided on the central column.

Abstract

The invention discloses a cutting pick type drill bit which comprises a drill barrel. A fixed disc is fixed to the bottom of the drill barrel. A drill disc is fixed to the fixed disc. Fixed drill teeth are arranged on the drill disc. Reaming drill teeth are hinged to the outer peripheral edge of the drill disc. A spring is arranged between the reaming drill teeth and the drill disc. The replaceable cutting pick type reaming drill teeth are added to the drill disc, the reaming drill teeth are opened after meeting solid rock and form a certain degree relative to original fixed drill teeth, the rock breaking force intensity is enhanced, the original fixed drill teeth are protected, meanwhile, the reaming drill teeth can be independently replaced after being abraded, the abrasion resistance of the drill bit is integrally improved, and the cost is saved.

Description

technical field [0001] The technical field of building construction of the present invention particularly relates to a pick type drill bit. Background technique [0002] The existing pick-type drill bit, the drill teeth are fixed, and the drill bit is easy to break when encountering large pieces of gravel or hard soil during the soil rotary excavation process. Once some drill teeth are broken, the wear rate of other drill teeth will be greatly increased. , is not conducive to cost control. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pick-type drill bit, which is suitable for excavation of crushed stone and construction dregs, effectively protects the drill teeth, and reduces the wear rate of the drill teeth. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical scheme: a pick type drill bit, comprising a drill cylinder, a fixed disk is fixed...
