Abstract
The utility model belongs to mining equipment, which is especially suitable for slag stop for gear wheel drilling machines and has the technical proposal that the main body of the slag bridge is table body with a hollow curved face, and the end with a bigger diameter of the table body is connected with a plane which is in pin connection with the lower end surface of a driller platform; the inner wall of the table body is provided with a convex slag stop ring, and the included angle between the curved face tangent line and the axis is less than 80 DEG. The utility model uses the guide action of the curved face to distribute slag reasonably, plays favorable actions of slag division and slag stop, avoids repeated slag-off, prolongs the service life of drill bits and reduces the labor strength of workers.
Description
The utility model belongs to winning equipment, and it is used that it is particularly suitable for the rotary drill pushing off the slag.
When rotary drill was holed during mining was produced, drilling rod contacted with ground by the positioning sleeve on the platform, by rotating and applying axial compression ore body was bored a hole.Apparatuses such as hydraulic pressure dop are installed above the platform, and the platform lower end is equipped with plane steel plate, doses the Collapsible canvas skirt between steel plate and platform, its objective is to prevent that slag from scurrying on the platform, and plane steel plate can prevent to spray slag and directly beat on anti-slag skirt.This pushing off the slag platform (device) is simple in structure, but the pushing off the slag weak effect can not play the effect of branch slag, causes and repeatedly repeats deslagging, makes slag density, increase in temperature in the boring, and unfavorable drill bit ventilates, heat radiation, with bearing, the axle sleeve premature failure that causes drill bit.
The utility model purpose is to overcome above-mentioned shortcoming of the prior art and a kind of mop of avoiding the repetition deslagging and scurry slag on platform is provided, and improves bit life, alleviates labor strength.
The purpose of this utility model is achieved by the following technical solution: the main body of rotary drill mop (2) is hollow curved surface stage body, the end that the stage body diameter is big links to each other with plane (1), the angle of curved surface tangent line and axial line is less than 80 °, and the stage body inwall has convex slag blocking ring (3).
The utility model utilizes the guide effect of curved body, and slag is reasonably distributed, and plays good branch slag, pushing off the slag effect, can avoid the repetition deslagging, improves bit life, alleviates labor strength.
Accompanying drawing is the structural representation of an embodiment of the utility model.
Further specify the utility model below in conjunction with accompanying drawing 1 by embodiment.
Main body of the present utility model (2) is hollow curved surface stage body, and its inwall is provided with three convex slag blocking rings (3).The end that curved surface stage body diameter is big links to each other with plane (1), and plane (1) is provided with hole (4), plane (1) adopts Bolt Connection with the lower surface of drilling machine platform, and the angle of mop curved surface tangent line and axial line is 60 °-70 °.
Claims (3)
1, a kind of rotary drill mop with plane (1), the main body (2) that it is characterized in that mop is hollow curved surface stage body, the end that the stage body diameter is big links to each other with plane (1), and the angle of curved surface tangent line and axial line is less than 80 °, and the stage body inwall has convex slag blocking ring (3).
2, according to the said rotary drill mop of claims 1, the angle that it is characterized in that said curved surface tangent line and axial line is 60 °-70 °.
3,, it is characterized in that plane (1) is provided with hole (4) according to claims 1 or 2 described rotary drill mops.
