The PLM3000 crusher is one of main transportation devices of a coal face in a coal mine, and the production capacity of the face is directly influenced if the working face can normally run. In the process of conveying coal by the reversed loader, the crushing shaft drives the crushing hammer head to rotate at a high speed to impact and cut large coal blocks, so that the large coal blocks are crushed into required block sizes. During the high-speed rotation of the hammer shaft of the crusher, the bearing also runs at a high speed and generates high heat, and if the heat is not effectively released, the bearing is damaged to a certain extent.

The conventional lubricating method is to install an oil cup on a bearing seat by punching and inject the lubricant, and the conventional lubricating method has the following disadvantages for operators in a well: (1) the operation is very difficult when the emulsifier is injected firstly, and an operator needs to detach the protective cover, find the oil cup on the bearing seat and align the grease gun with the oil cup hole to inject the lubricant at a small point. (2) Secondly, the natural conditions in the pit are very complicated, and the safety accident may happen to operating personnel in the process of dismounting the protective cover.

SUMMERY OF THE UTILITY MODEL

In order to the above situation, the utility model relates to an external oiling system is designed and is lubricated the operation to the bearing of hammer spindle, has both made things convenient for operating personnel's oiling operation in the pit, has protected operating personnel's personal safety problem again.

In order to solve the technical problem, the utility model provides a technical scheme is: an external oiling device system comprises a mounting plate, a high-pressure rubber pipe, a joint and an oil cup; the mounting plate is fixedly connected to the outer side of the main frame body of the machine, and a plurality of connecting pipes are arranged on the mounting plate; the two ends of the high-pressure rubber pipes are provided with joints, one end of each high-pressure rubber pipe is connected with an oil hole of a machine, the other end of each high-pressure rubber pipe is fixed at the upper end of a connecting pipe of the mounting plate, and a plurality of oil cups are correspondingly arranged below the mounting plate and fixedly connected with the lower end of the connecting pipe.

The high-pressure rubber pipes are in a linear array and arranged on one side of the mounting plate; the joint and the high-pressure rubber pipe are coaxial.

The lower end of the connecting pipe of the mounting plate is in threaded connection with the oil cup, so that the mounting plate is convenient to detach and replace, and can be suitable for lubricating parts in different positions, types and models.

The other side of the mounting plate is provided with a bolt and a nut which are connected to the main frame body of the machine; the bolt is high-strength bolt, and the nut is locknut.

One end of the high-pressure rubber pipe also comprises an elbow body, an assembly angle exists between the elbow body and the joint close to one end of the mounting plate, and the high-pressure rubber pipe is different in length, so that the high-pressure rubber pipe is suitable for positions to be lubricated at different positions and angles on a machine.

The high-pressure rubber pipe also comprises a U-shaped clamp used for fixing the position, and the U-shaped clamp is used for guiding the direction of the high-pressure rubber pipe and limiting the transverse displacement of the high-pressure rubber pipe.

With this configuration, when lubricating the bearing of the downhole equipment, it is possible to directly connect a device such as a grease gun to the outside of the equipment without detaching the device such as the bearing cap and the protective cover, and perform the operation of injecting the lubricating oil. The working process of operators is simplified, the working efficiency during lubrication is improved, and meanwhile, the safety of underground operation is improved.
