Abstract
The utility model relates to a grooving double knives head chain cutter for equipment in advance belongs to grooving equipment accessories in advance, including cutter body, two carbide tool bits and blade holder, the key feature is that the front projection of whole cutter comprises with a rectangle an approximate isosceles trapezoid of inversion (trapezoidal long base is slightly inwards sunken), and wherein coincide in rectangle minor face and trapezoidal short base. Both ends are provided with an open groove respectively about the cutter body top surface, and the welding of open inslot has the carbide tool bit. During the use, no matter be the feed or move back the sword that the carbide tool bit contacts earlier the ground, because the carbide tool bit exposes, and the direct contact rock, avoided the directness wearing and tearing of ground to the cutter body, effectively protect the cutter body, avoided the cutter body phenomenon of wearing and tearing too early. Have resistance to wear, long service life's effect, improved the wear resistance of cutter body.
Description
Technical field
This utility model relates to tunnel construction machinery equipment field, especially relates to a kind of precutting trough equipment Double-cutter head chain type cutter.
Background technology
Tunnel pre-cut channel process is to utilize work head to be ahead of face along tunnel cross-section outline to cut out circumferential groove, and concrete perfusion is formed super simultaneously
The construction of front supporting construction.Use this method to be greatly improved the Mechanization Level of construction, efficiently control ground settlement, thus can be work people
Member and equipment provide cleaning, the working condition of safety, and compared to Shield-type machinery, its cost is relatively low.Chain type cutter is to carry out rock on precutting trough equipment
The cutting element of groove excavation, on market, existing chain type cutter on precutting trough equipment is fewer, and existing chain type cutter is typically unsuitable for using
On precutting trough equipment.Therefore, a kind of precutting trough equipment Double-cutter head chain type cutter of design has great importance.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art to provide a kind of precutting trough equipment Double-cutter head chain type cutter, this chain type
Cutting knife is not for consolidating and the precutting trough equipment of constructing tunnel in soft rock strata.
This utility model is achieved in that a kind of precutting trough equipment Double-cutter head chain type cutter, mainly includes cutter hub, two carbide bits
And base, it is characterised in that: the front projection of whole cutting knife is by an approximate inverse isosceles trapezoid (caving in slightly inward in trapezoidal long base) and
Individual rectangle forms, wherein rectangle minor face and trapezoidal short base coincident.It is respectively arranged with an open type groove, in open type groove at the two ends, left and right of cutter hub end face
It is welded with carbide bit.
After this utility model uses said structure, first contacted ground by carbide bit, owing to carbide bit exposes, and directly contact
Rock, it is to avoid the ground directly abrasion to cutter hub, effectively protect cutter hub, it is to avoid cutter hub premature abrasion phenomenon.There is wear-resistant, service life
Long effect, improves the anti-wear performance of cutter hub.

Fig. 3 is carbide bit structural representation of the present utility model
Detailed description of the invention
Below in conjunction with the accompanying drawings of the present utility model being embodied as is described further.
As shown in drawings, this utility model is a kind of precutting trough equipment Double-cutter head chain type cutter, by cutter hub (1), two carbide bits
(2), base (3) composition, the front projection of whole cutting knife be by an approximate inverse isosceles trapezoid (caving in slightly inward in trapezoidal long base) and
One rectangle composition, wherein rectangle minor face and trapezoidal short base coincident.This utility model is two ends, the left and right difference of the end face (6) in cutter hub (1)
It is provided with an open type groove, in open type groove, is welded with carbide bit (2).As a example by the carbide bit (2) on the left side, carbide cutter tool
The end face (21) of head (2) is concordant with the end face of cutter hub (1) (6), the side (22) of carbide bit (2) and the side of cutter hub (1)
Face (4) is concordant.The front projection of carbide bit (2) is similar to a right-angled trapezium, the left surface (22) of left side carbide bit (2)
Gradient symmetrical before and after being related to end face (21), the prominent sharp comer (23) thus constituted is the portion that carbide bit (2) is the most prominent
Point, it is cutting part the most sharp-pointed in overall cutter head.As required, the cutter hub (1) of varying number (1-3) can be used with different angles and the end
Seat (3) welding, base is connected with the chain on sprocket wheel, and under the drive of chain, ground is cut by chain type cutter.
During use, chain type cutter is contained on chain, and chain followed by sprocket, the carbide bit (2) during feed, on side
First contact ground, be done directly and ground crushed and cuts.When chain cutter cuts ground withdrawing, the direct tactite of carbide bit of opposite side
Slag and the earth cut, discharge rock slag and the earth cut along band, prevents rock slag and the earth that cuts from blocking cutter and the cutter beam of precutting trough equipment.Nothing
Opinion feed or withdrawing process, carbide bit (2) exposes and directly contacts ground, effectively protects cutter hub (1), improves cutter hub (1)
Anti-wear performance.
Claims (4)
1. a precutting trough equipment Double-cutter head chain type cutter, including cutter hub (1), two carbide bits (2) and base (3), it is characterized in that: the front projection of whole chain type cutter is made up of isosceles trapezoid and a rectangle of an approximate inverse, cave in slightly inward in trapezoidal long base, wherein rectangle minor face and trapezoidal short base coincident, it is respectively arranged with an open type groove at the two ends, left and right of cutter hub (1) end face, in open type groove, is welded with carbide bit (2).
A kind of precutting trough equipment Double-cutter head chain type cutter the most according to claim 1, it is characterized in that: described carbide bit (2) end face and cutter hub (1) either flush, described carbide bit (2) side is concordant with cutter hub (1) side.
