However, the manual filling of lubricating grease has the following defects: 1. The rock drilling operation has a high intensity, and it is necessary to manually fill the grease every minute on average to pick up the drill rod. Low efficiency; 2. When actually adding grease, due to human operation, the amount of lubricating grease applied to the thread of the drill rod is different. Due to the uneven distribution of grease, it is easy to cause insufficient lubrication between the threads of the drill rod, and some unlubricated threads cannot be fully lubricated. 3. When adding oil manually, due to the unstable state of the rock in the rock drilling area, if any rock falls off, it will cause harm to the operator

Embodiment Construction
[0018] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0019] Such as Figure 1~3 As shown, the drill rod thread lubrication system of the present invention is used to add lubricating grease to the drill rod thread. The drill rod has a threaded connection and includes a lubricating head 1. The oil nozzle 12 is composed of a first oil delivery pipeline 101 opened in the body 1, a second oil delivery pipeline 111 opened in the lubricating sleeve 11, and the filter oil nozzle 12 is embedded and installed between the body 10 and the lubricating sleeve 11. The two ends of the oil filter nozzle 12 are respectively connected to the first oil delivery pipeline 101 and the second oil delivery pipeline 111; the lubricating sleeve 11 is provided with a recessed part 110 capable of accommodating the threaded connection part of the drill rod, and the recessed part 110 is provided with a plurality of oil guide g...

The invention discloses a drill rod thread lubricating system. The system comprises a lubricating head, wherein the lubricating head is composed of a body, a lubricating sleeve and a filtering oil nozzle; a first oil conveying pipeline is formed in the body; a second oil conveying pipeline is formed in the lubricating sleeve; the filtering oil nozzle is embedded and mounted between the body and the lubricating sleeve; the two ends of the filtering oil nozzle are connected with the first oil conveying pipeline and the second oil conveying pipeline respectively; a concave part capable of containing a drill rod thread connection part is formed on the lubricating sleeve; a plurality of oil conducting grooves communicated with the second oil conveying pipeline are formed in the concave part; the body is provided with an oil inlet connector and the oil inlet connector is communicated with the first oil conveying pipeline; and the body is fixedly connected with the lubricating sleeve. According to the drill rod thread lubricating system disclosed by the invention, the drill rod thread lubricating effect is effectively improved and the service life of a drill rod is prolonged.
Description
technical field [0001] The invention relates to the technical field of rock drilling equipment, in particular to a drilling rod thread lubrication system for an underground mining rock drilling jumbo. Background technique [0002] During the working process of the underground mining rock drilling jumbo, according to the depth requirements of the mining blast hole, it is often necessary to connect a plurality of drill rods through threads to complete a drilling operation. During the drilling process, the drill rod needs to do high-frequency, high-intensity reciprocating impact motion. Due to the high hardness of the rock and the uneven hardness distribution, under the impact of this high frequency, the friction force of the threaded connection of the drill rod increases, resulting in difficulty or even damage to the drill rod, resulting in waste of the drill rod and reduced production efficiency. [0003] In order to avoid this situation, at present, most of the drill rod th...
