Abstract
A coal cutting drilling tool comprises a drill rod and a drill bit, a coal cutting tool bit is arranged on the drill rod at the rear end of the drill bit, and the coal cutting tool bit is obliquely arranged towards the drill bit; the coal cutting tool bit comprises a short coal cutting tool bit and a long coal cutting tool bit, the short coal cutting tool bit is arranged on the rear side of the drill bit, the long coal cutting tool bit is arranged on the rear side of the short coal cutting tool bit and keeps a certain distance and a certain angle with the rear side; the coal cutting tool bit is evenly and obliquely arranged on the periphery of the drill rod; the tool face of the coal cutting tool bit is in the same direction with the tool face of the drill bit; and the coal cutting tool bit is fixedly connected with the drill rod. The utility model is reasonable in design, simple in structure, convenient to use and low in cost, an electric coal drill is adopted for providing power, andthe cutting efficiency is times higher than manual coal cutting efficiency. The coal-cutting drilling tool is safe and reliable to use, and is firm and durable, not only suitable for coal cutting, but also suitable for slotting hitches and sockets, further improves the operation quality and ensures personnel safety.
Description
Technical field
The utility model relates to a kind of broken coal borer tool that is applicable to colliery down-hole coal excavation, driving face.
Background technology
Because the geological conditions more complicated is special under the coal mine; particularly coal-face and driving face are in process of production; through regular meeting run into that gas is big, roof strata is broken, the coal seam covers and deposits that structure is extremely unstable, inbreak is hurted sb.'s feelings easily; can not carry out perforating explosion etc. again in particular cases; main by the broken coal operation of artificial pickaxe; labor strength is big, and efficient is very low, directly influences output of coal and driving speed.At present, known electric coal borer bar because drill pipe diameter is little, can only only limit to jewel hole, can not be used for brokenly coal and use.
The utility model content
It is a kind of rational in infrastructure that the utility model purpose is to provide, broken coal efficient height, the broken coal borer tool that result of use is outstanding.
To achieve these goals, the utility model adopts following technical scheme: a kind of broken coal borer tool, comprise drilling rod and drill bit, and the drilling rod of drill bit rear end is provided with brokenly the coal cutter head, and broken coal cutter head is obliquely installed to the drill bit direction.
Described broken coal cutter head can be made as crooked cutter head or straight knife head.
Described broken coal cutter head comprises brokenly coal short sword head and broken coal rimmer knife head, and broken coal short sword head is arranged on the rear side of drill bit, and broken coal rimmer knife head is arranged on brokenly the rear side of coal short sword head and keeps at a certain distance away and inclination differs the certain angle setting.
Described broken coal short sword head and broken coal rimmer knife head evenly are obliquely installed around drilling rod.
The knife face of described broken coal cutter head and the knife face of drill bit are same direction.
Movable being connected on the drilling rod of described broken coal cutter head.
Described broken coal cutter head is fixedly connected on the drilling rod.
The utility model is reasonable in design, and is simple in structure, easy to operate, with low cost, utilizes electric coal borer to do power, and broken coal efficient is higher than artificial broken more than five times of coal efficient.And safe and reliable, sturdy and durable, easy to operate, be not only applicable to brokenly coal, but also be applicable to and draw hitch and draw needling, can do operation quality well, can guarantee personal safety again.Broken coal rimmer knife head is arranged on brokenly the rear side of coal short sword head, broken coal short sword head is arranged on the rear side of rotary head, keep at a certain distance away each other and differ the certain angle setting, can keep the drilling tool steady running, alleviate the load of electric coal borer, can enlarge brokenly the coal area again, improve broken coal efficient.
Description of drawings
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the structural representation of embodiment 2.
The specific embodiment
Embodiment 1: broken coal borer tool as shown in Figure 1, comprise drilling rod 1 and drill bit 2, the drilling rod of drill bit 2 rear ends be provided with brokenly the coal cutter head, broken coal cutter head is obliquely installed to drill bit 2 directions, broken coal is the straight knife head to the end in the present embodiment.
Broken coal cutter head comprises brokenly coal short sword head 3 and broken coal rimmer knife head 4, broken 3 rear ends that are arranged on drill bit 2 of coal short sword, broken coal rimmer knife head 4 is arranged on brokenly the rear side of coal short sword head 3 and space certain distance and inclination and differs the certain angle setting, can keep the drilling tool steady running, alleviate the load of electric coal borer, can enlarge brokenly the coal area again, improve broken coal efficient.Broken coal short sword evenly is arranged on around the drilling rod 1, and the knife face of broken coal cutter head and the knife face of drill bit 2 are same direction.Broken coal cutter head is movable to be connected on the drilling rod 1 or to be fixedly connected on the drilling rod 1.
During work, earlier drilling rod 1 is inserted electric coal borer, 2 pairs of positions of living to need broken coal of drill bit start electric coal borer then and drive the drilling tool running, by the rotation cutting bump between drill bit 2, broken coal short sword head 3, broken coal rimmer knife head 4 and the coal seam, thereby reach brokenly the coal effect.
Embodiment 2: broken coal borer tool as shown in Figure 2, difference from Example 1 be broken coal cutter head (broken coal short sword head 3 and broken coal rimmer knife head 4) for bending to the end, result of use is better.
Claims (7)
