Abstract

A tool for carrying out effective chipping operations is provided.　A striking surface 3b on one side of this hammer is angled, and a chipping chisel and a head part 1 are integrated. When swung downwards, the chipping chisel 4, 5, 6, 7, 8, 9 describes an arcuate path, and has highly effective chipping.

Description

斫りノミ付きハンマーHammer with chipping chisel
　従来のハンマーは打撃面が両面あるが、片方の打撃面しか使用されていないため、頭部体１の打撃面３ｂに斫りノミを一体化し、両面が使えるようにした。 The conventional hammer has both striking surfaces, but since only one striking surface is used, a chisel is integrated with the striking surface 3b of the head body 1 so that both sides can be used.

Prior Art Document Patent Document Patent Document 1: Japanese Patent Application Laid-Open No. 2019-100132
The striking surface 3b of the head body 1 of the hammer is angled and integrated with the chisel to perform the chipping work.
Means for solving the problem The striking surface 3b is angled. The cutting edge 6, 5, 4 and 6, 8, 7 and 6, 11 and 6, 12 of the chipping chisel along the arc locus are integrated with the striking surface 3b of the head body 1.
Effect of the invention When the striking surface 3b of the head body 1 is swung down, by attaching a chipping chisel, the cutting edge 6 of the chipping chisel hits the concrete soil or the like vertically, so that the chipping is more effective. Become.

FIG. 2 is a usage state diagram in which the head body 1 is swung down into an arc locus.
FIG. 3 is a state diagram of driving a pile using the striking surface 2a of the head body 1.
　本発明の実施の形態を図面に基づいて説明する。図１~図２において略円頭形打撃面３ｂに角度をつける事により、斫りノミの刃６，５，４と６，８，７と６，１２と６，１１を頭部体１の３ｂ面と一体化したものである。 An embodiment of the present invention will be described with reference to the drawings. By angling the substantially circular head-shaped striking surface 3b in FIGS. 1 to 2, the blades of the chipping chisel 6, 5, 4, 6, 8, 7, 6, 12 and 6, 11 can be attached to the head body 1. It is integrated with the 3b surface.
　ハンマーを円弧軌跡に振り下ろした際、打撃面３ｂに角度を付ける事により円弧軌跡に沿った斫りノミの刃６が土間コンクリート等に垂直に当たり、従来のハンマーより斫り効果が高い。 When the hammer is swung down on the arc locus, the blade 6 of the chipping chisel along the arc locus hits the soil concrete or the like vertically by angling the striking surface 3b, and the chipping effect is higher than that of the conventional hammer.
　頭部体１の打撃面２ａは、従来のハンマーとして杭打ち作業等にも使用できる。 The striking surface 2a of the head body 1 can be used as a conventional hammer for pile driving work and the like.
　従来の斫り機は、軽微な斫り作業でも電力及びエアーコンプレッサー等の動力源を必要とするが、斫りノミ付きハンマーでの作業なら、電源等を必要とせずとも軽微な斫り作業ができる。打撃面２ａは従来のハンマーとして使用でき、経済的である。 Conventional chipping machines require a power source such as electric power and an air compressor even for minor chipping work, but when working with a hammer with a chipping chisel, minor chipping work can be done without the need for a power source, etc. it can. The striking surface 2a can be used as a conventional hammer and is economical.
