Abstract

The utility model relates to a can enough improve flat chisel excavation efficiency effectively, can make the flat chisel head have two groove flat chisels of good wearability again, including square handle, pole body and flat chisel point, flat chisel point both sides have protruding long chisel muscle, the centre has protruding short chisel muscle, forms two grooves between both sides long chisel muscle and the middle short chisel muscle. The advantages are that: the design that respectively has two flat grooves on the both sides face of flat chisel, not only promoted the sharpness of flat chisel head, the during operation excavation is fast, and the ash bits of excavating in the use discharge smoothly from two grooves moreover, make flat chisel head can not produce the heat and reduce flat chisel head intensity to improve the life-span of flat chisel, ensured the result of use, flat chisel outward appearance is pleasing to the eye simultaneously.

Description

Two-groove flat chisel

Technical Field

The utility model relates to a can enough improve flat chisel effectively and chisel efficiency, can make the flat chisel head have two groove flat chisels of good wearability again, belong to flat chisel and make the field.

Background

The applicant's prior patent CN205734743U, entitled "a tooth-shaped chisel", includes a chisel, and is characterized in that: the head of the flat chisel rod body is embedded with a superhard alloy head, the head of the flat chisel rod body is spliced with the superhard alloy head and subjected to hot forging forming, and the head of the superhard alloy head is a tooth-shaped head. Because the two sides of the head of the flat chisel are of a plane structure and do not have bending-resistant ribs, the bending strength needs to be improved; secondly, because two surfaces of the tooth-shaped head tooth are planes, when in chiseling, the two surfaces of the tooth-shaped head tooth are in surface contact, and a drill prying fulcrum is not arranged, so that the drill prying capability is weak.

Disclosure of Invention

The design purpose is as follows: on the basis of the background technology, a two-groove flat chisel which has strong drilling and prying capabilities, enables the head of the flat chisel to have good abrasion resistance and can effectively improve the chiseling efficiency of the flat chisel is designed.

The design scheme is as follows: in order to achieve the above design objectives. The utility model discloses in structural design, flat chisel point both sides have protruding long chisel point muscle, the centre has protruding short chisel muscle, the design that forms two grooves between the long chisel muscle in both sides and the middle short chisel muscle is the main technical characteristic of asking for of the invention. The purpose of this design is: when two grooves are arranged on two sides of the head of the flat chisel, the two grooves are equal to three reinforcing ribs, and the reinforcing ribs can effectively improve the bending strength of the head of the flat chisel. Secondly, when two sides of the chisel head are designed to be long chisel ribs and the middle is short chisel rib, two sides of the flat chisel are provided with three manual chisel ribs, and the sections of the three prying chisel ribs are triangles with narrow bottom width surfaces, which is equal to the fact that the contact area of chisel rib tips is small, so that the drilling force is large and the efficiency is high; after two sides are chiseled the muscle point and are bored into, middle chisel muscle is owing to be the interval cooperation with two even chisel muscle, therefore the drilling power is greater than a flat chisel of face far away simultaneously, lies in the terminal surface that forms between both sides chisel muscle and the middle chisel muscle again to chisel sled face formation and bore sled impact vibration under the effect of external force, very easily with two chisel muscle portions by chisel sled thing shatter, shake pine, shake garrulous.

The technical scheme is as follows: the utility model provides a two groove flat chisel, includes square handle, pole body and flat chisel point, flat chisel point both sides have protruding long chisel muscle, the centre has protruding short chisel muscle, forms two grooves between protruding long chisel muscle in both sides and the protruding short chisel muscle in centre.

Compared with the prior art, the utility model, respectively have the design of two flat grooves on the both sides face of flat chisel, not only promoted the sharpness of flat chisel head, the during operation excavation is fast, and the ash bits of excavating in the use discharges smoothly from two grooves moreover, makes the flat chisel head can not produce the heat and reduces flat chisel head intensity to improve the life-span of flat chisel, ensured the result of use, the flat chisel outward appearance is pleasing to the eye simultaneously.

Detailed Description

Example 1: reference is made to fig. 1-4. The utility model provides a two groove flat chisel, includes square handle 1, pole body 2 and

flat chisel point

3, 3 both sides of flat chisel point have protruding long chisel muscle 31, the centre has protruding short chisel muscle 32, form two grooves 33 between protruding long chisel muscle 31 of both sides and the protruding short chisel muscle 32 of centre. The section of the convex long chisel rib 31 is in a double-head pickaxe shape and has the function of a pickaxe, and the section of the convex short chisel rib 32 is in an arc-shaped chisel head and has the function of a sharp chisel. The chisel edge 3 has two grooves 33 on both sides. The manufacturing process is the prior art and will not be described herein.

It is to be understood that: although above-mentioned embodiment is right the utility model discloses a design has done more detailed word description, but these word descriptions, are only right the utility model relates to a simple word description of idea, rather than right the utility model relates to a restriction of idea, any do not surpass the utility model relates to a combination, increase or the modification of idea all fall into the utility model discloses a within the protection scope.
