Description
Technical field:
This utility model relates to the technical field of rock drill, more specifically to a kind of drill rod being applied to hydraulic gate.
Background technology:
Rock drill, is used to the instrument of direct quarrying stone.Its Drilling on rock stratum goes out borehole, in order to puts into explosive and removes to blow rock, thus completes quarrying stone or other stonework.And when rock drill operation, drill rod is by reciprocating impact in rock stratum, the broken borehole that formed in local, rock stratum, broken rock stratum can form substantial amounts of dust, to the healthy adverse effect of bringing of workmen, even can cause pneumoconiosis accident.
Utility model content:
The purpose of this utility model is aiming at the deficiency of prior art, and provides a kind of drill rod being applied to hydraulic gate, can draw the dust that operation produces, thus ensured that workmen's is healthy during its drill rod operation.
Technology solution of the present utility model is as follows:
A kind of drill rod being applied to hydraulic gate, drill steel including hexagon, the two ends of drill steel form drill rod head, the groove that 3 roads are vertical is formed on the sidewall of drill steel, grove shaped circumferential is evenly distributed on drill steel, in groove, grafting is fixed with vertical sliver, form vertical conduit on sliver and the bottom surface with groove is enclosed to set and formed dust absorption passage, the length of sliver less than the length of groove and leaves gap with the two ends of groove, the drill steel upper sleeve of groove one end is fixed with axle sleeve, the air intake notch being connected with groove is formed on the inwall of axle sleeve, the cannelure that air intake notch is connected is formed in axle sleeve, the outer wall of axle sleeve is fixed with the air pipe connector being connected with cannelure.
Several screwed holes are formed on the two side of described drill steel groove, screwed hole is evenly distributed on the two side of drill steel groove and runs through two drill steel sidewalls adjacent with recess sidewall, being bolted with jackscrew in screwed hole, jackscrew is resisted against on sliver, and the width of sliver is equal to the width of groove.
Described axle sleeve is fastened by bolts on drill steel.
The beneficial effects of the utility model are:
1, it is provided with dust absorption passage on drill rod, the dust produced when absorbing drill rod operation by external dust absorption fan, thus reduces the dust harm to workmen, has ensured that workmen's is healthy.
2, the dust absorption passage on its drill rod is convenient is dredged by dismounting, it is thus possible to avoid the blocking of dust absorption passage.
3, its its drill rod energy two used uses, and moves fixed hub simultaneously, and when its dust absorption passage is two operation, dust suction uses.
Accompanying drawing illustrates:
Fig. 1 is the structural representation that this utility model is three-dimensional；
Fig. 2 is the structural representation that this utility model is faced；
Fig. 3 is the cross-sectional schematic in Fig. 2 at A-A；
Fig. 4 is the cross-sectional schematic in Fig. 2 at A-A.
In figure: 1, drill steel；11, drill rod head；12, groove；13, screwed hole；2, sliver；21, dust absorption passage；3, axle sleeve；31, air inlet notch；32, cannelure；4, air pipe connector；5, jackscrew.
Detailed description of the invention:
nullEmbodiment: as shown in Fig. 1 is to 4，A kind of drill rod being applied to hydraulic gate，Drill steel 1 including hexagon，The two ends of drill steel 1 form drill rod head 11，The vertical groove in 3 roads 12 is formed on the sidewall of drill steel 1，Groove 12 annular is evenly distributed on drill steel 1，In groove 12, grafting is fixed with vertical sliver 2，Form vertical conduit on sliver 2 and the bottom surface with groove 12 is enclosed to set and formed dust absorption passage 21，The length of sliver 2 less than the length of groove 12 and leaves gap with the two ends of groove 12，Drill steel 1 upper sleeve of groove 12 one end is fixed with axle sleeve 3，The air intake notch 31 being connected with groove 12 is formed on the inwall of axle sleeve 3，The cannelure 32 that air intake notch 31 is connected is formed in axle sleeve 3，The outer wall of axle sleeve 3 is fixed with the air pipe connector 4 being connected with cannelure 32.
Several screwed holes 13 are formed on the two side of described drill steel 1 groove 12, screwed hole 13 is evenly distributed on the two side of drill steel 1 groove 12 and runs through two drill steel 1 sidewalls adjacent with groove 12 sidewall, jackscrew 5 it is bolted with in screwed hole 13, jackscrew 5 is resisted against on sliver 2, and the width of sliver 2 is equal to the width of groove 12.
Described axle sleeve 3 is fastened by bolts on drill steel 1.
Operation principle: this utility model is for set up groove 11 on the basis of existing drill rod, sliver 2 it is plugged with in groove 11, the two ends of the two ends unsealing groove 11 of sliver 2, thus the two ends of groove 11 all can as entering-dust mouth use, with one end of groove 11 as entering-dust mouth.Other end connecting bushing 3 seals, and spindle set 3 is as being excessively connected with sweep-up pipe, thus drill rod is when operation, can pass through one end of groove 11, dust absorption passage 21, axle sleeve 3 are given a dinner of welcome, minimizing dust, the reduction dust harm to workmen.
