Problems solved by technology

[0003] The obvious defects of the oil supply device used in the rock drilling machine before: 1. The shell is semi-closed at one end, and the other end is an open structure, which has low strength and is easy to break
2. After the adjustment of the oil volume is completed, the position of the adjustment handle changes in the severe working vibration, and the oil supply is not supplied or the oil volume is large, which will cause the rock drill to be unstable and ...

Embodiment Construction

[0007] The use of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0008] Since the casing 5 and the welding assembly 1 of the oil adjusting mandrel and the parts such as the rubber ring and the snap ring form a completely sealed volume chamber, the lubricating oil is filled through the oil plug 6, and the compressed air is welded by the oil adjusting mandrel during the use of the rock drill. The central hole of component 1 passes through at high speed, and the small hole e on the oil-adjusting mandrel is blown into the sealing chamber. Due to the increase in pressure, the oil in the sealing chamber passes through hole a, filter screen 4 hole b. and Hole c. Through the adjustment gap ring between the oil volume adjustment sleeve 2 and the oil adjustment mandrel 1, it enters the oil outlet pipe 14 and enters the rock drill with compressed air to form lubrication. The amount of lubricating oil can be realized by turning the ...

Abstract

The invention provides an oil filling device, which relates to new oil ejector field. The lubricating device in rock drilling project is sensitive to the adhesive of oil and is not beneficial to the excellent lubrication and the state that the oil adjustor is jammed and can not supply oil normally, the shell is supported by one end, and thus the intensity is low. The invention uses oil adjusting blade aperture design, solves the problem that the oil adjustor is sensitive to the oil, and the oil quantity is not stable, and the invention has a new designed filter mechanism, and it also increase the elastic localization mechanism to make the oil quantity stable, it uses shell structure whose two ends are half sealed, so the intensity is upgraded greatly.

Description

technical field [0001] The invention relates to the field of a novel lubricator, aiming at lubricating rock drilling machines in use. Background technique [0002] Because the work of the rock drill is a violent impact and rotation movement and works in a dusty environment. To ensure the normal operation of the rock drill, it is very important that its lubrication requirements should be accurate, stable and reliable. [0003] The obvious defects of the oil supply device in the use of the rock drilling machine before: 1, the housing is that one end is semi-closed, and the other end is an open structure, and its own strength is low and easy to break. 2. After the adjustment of the oil volume is completed, the position of the adjustment handle changes in the severe working vibration, and the oil supply is not supplied or the oil volume is large, which will cause the rock drill to be unstable and damaged during use. 3. The valve core used for the oil supply device is a circula...
