Problems solved by technology

[0003] The purpose of the present invention is to solve the problems caused by the inclined roadheader expansion part when the cutting head cuts downwards by changing the position of the inner port of the ventilation structure without changing the position of the ventilation hole through a new type of ventilation structure. Cavity lube would overflow through the vent hole

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] The ventilation structure of the present invention is formed by connecting the telescopic outer cylinder and the ventilation pipe, the ventilation pipe communicates with the ventilation hole on the telescopic outer cylinder, and the front port and both sides of the ventilation pipe are connected with the telescopic outer cylinder by welding.

[0018] Such as Figure 1-Figure 2 As shown, in this embodiment, the vent pipe 4 in the ventilation structure is connected with the telescopic outer cylinder 1 by welding, the vent pipe 4 is welded on the inner wall of the telescopic outer cylinder 1, and the vent pipe 4 and the vent hole on the telescopic outer cylinder 1 3 are connected, the center of the vent pipe 4 is aligned with the center of the vent hole 3 on the telescopic outer cylinder 1, and the front port 2 and both sides of the vent pipe are blocked with the t...

Abstract

The invention relates to a device for a coal mine development machine, in particular to a novel ventilating structure. The ventilating structure is formed by connecting a telescopic outer cylinder with a ventilating pipe, wherein the ventilating pipe is communicated with a vent hole on the telescopic outer cylinder. The ventilating structure is arranged in a telescopic part of the development machine; the vent hole on the telescopic outer cylinder in the telescopic part is connected with the ventilating pipe; and a front port and two sides of the ventilating pipe are welded with the telescopic outer cylinder. Because the vent hole is at a limiting position and cannot move backwards, when a cutting unit cuts downwards at that moment, the lubricating oil in a cavity can overflow from the vent hole to cause oil leakage. By using the length of the ventilating pipe, and changing the position of an inner port of the ventilating structure on the premise of not changing the position of the vent hole, the problem of oil leakage at the back end of the cutting unit of the development machine caused by the lubricating oil in the cavity which overflows through the vent hole when the cutting unit of the development machine cuts downwards is solved.

Description

technical field [0001] The invention relates to equipment for coal mine roadheaders, in particular to a novel ventilation structure. Background technique [0002] Roadheader equipment is a main equipment for roadway mining in coal mines. It is a fast tunneling equipment for underground roadway that integrates roadway mining, collection and transportation. The lubricating oil will be tilted, because the position of the vent hole on the telescopic outer cylinder is already at the limit position, and it cannot move backward. At this time, when the cutting part cuts downward, the lubricating oil in the cavity will overflow the vent hole, It overflows from the vent hole, causing oil leakage, and finally oil leakage at the rear end of the cutting part. Contents of the invention [0003] The purpose of the present invention is to solve the problems caused by the inclined roadheader expansion part when the cutting head cuts downwards by changing the position of the inner port of ...
