Abstract
The utility model provides a mining roller bit structure comprising a bit body and a bearing mounted in the bit body, wherein the bit body is provided with a cooling channel; the cooling channel is opposite to the bearing; an inner thread is arranged at the upper part of the cooling channel; a dreg pipe is provided with an outer thread matched with the inner thread of the cooling channel; the dreg pipe is hermetically connected to the cooling channel through the thread; a screw hole is arranged at the top of a through hole in the dreg pipe; and the screw hole is screwed with a dreg pipe bolt to form thread sealing connection. The dreg pipe is used for effectively preventing impurities from entering into the bearing; an oil injecting channel is arranged, the injection of lubricating oil in the bearing is not influenced and the oil can be repeatedly injected when the oil is lacked in a working process of a mining bit; and the oil in the bearing can be protected and the oil is prevented from being leaked; and the mining roller bit structure is convenient to convenient and is easy to detach.
Description
Technical field
The utility model relates to a kind of mining cone bit structure, belongs to mining drill bit technical field.
Background technology
Blasthole tricone rock bit is the important tool that is used to exploit outdoors iron ore, colliery and nonferrous metals ore; During drill bit work; There is oil injection structure to make bearing be in semi open model in the cooling duct; Bearing grease leaks easily, easily steam impurity is brought into wherein when compressed air is through the cooling duct simultaneously.Therefore, the needs design is a kind of can be to the drill bit structure of protection.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that prior art exists, and a kind of mining cone bit structure is provided.
The purpose of the utility model realizes through following technical scheme:
The mining cone bit structure comprises drill body and is installed on bearing wherein that characteristics are: said drill body is provided with the cooling duct; Cooling duct and bearing are relative; The top of cooling duct is provided with internal thread, and the slag pipe is provided with the external screw thread that matches with the cooling duct internal thread, and the slag pipe is connected in the cooling duct through thread seal; The top of the interior bone of slag pipe is provided with screw, and its screw spins mutually with slag pipe bolt and forms the thread seal connection.
Further, above-mentioned mining cone bit structure, wherein, said slag pipe bolt is a hex bolts.
The substantive distinguishing features of the utility model technical scheme is mainly reflected in progressive:
The utility model structure is unique, and it is inner that the slag pipe effectively stops impurity to get into bearing, has the oiling passage, does not have influence on the injection of bearing internal lubrication oil, and can grease lacks in mining drill bit work the time, repeats oiling; Can protect the inner grease of bearing, prevent the leakage of grease; Easy for installation, quick detachable; It is inner to stop impurity to get into bearing, increases the self-protection function of bearing, and when guaranteeing bearing working, impurity can not invaded bearing, prolongs the application life of bearing.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Fig. 1: the structural representation of the utility model.
The specific embodiment
Design and a kind ofly guarantee that the bit bearing cleaning is dustless, prevent that the bearing internal grease from revealing, can repeat the mining drill header structure of the inner oiling of bearing.
As shown in Figure 1, the mining cone bit structure comprises drill body 1 and is installed on bearing wherein; Drill body 1 is provided with cooling duct 2, and cooling duct 2 is relative with bearing, and the top of cooling duct 2 is provided with internal thread; Slag pipe 3 is provided with the external screw thread that matches with the cooling duct internal thread, and slag pipe 3 is connected in the cooling duct 2 through thread seal, and the top of the interior bone of slag pipe is provided with screw; Its screw spins mutually with slag pipe bolt 4 and forms the thread seal connection, and slag pipe bolt 4 is a hex bolts.
It is inner that slag pipe 3 effectively stops impurity to get into bearings, has the oiling passage, do not have influence on the injection of bearing internal lubrication oil, and can grease lacks in mining drill bit work the time, repeat oiling.Can protect the inner grease of bearing, prevent the leakage of grease.Easy for installation, quick detachable.
In sum, the utility model structure is unique, and it is inner to stop impurity to get into bearing, increases the self-protection function of bearing, and when guaranteeing bearing working, impurity can not invaded bearing, can prolong the application life of bearing.
What need understand is: the above only is the preferred implementation of the utility model; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
Claims (2)
