Deep-well high-stress coal rock stepped roller

A high-stress, ladder-shaped technology, applied in the field of shearer drums for cutting high-stress coal and rock in deep wells, can solve the problem that the size of the shearer cannot be too large and cannot meet the needs of high-stress coal and rock cutting in deep wells. Problems such as the size limitation of the cutting motor can be solved to achieve the effect of improving mining efficiency and safety conditions, and the shape of the drum hub is simple and easy to manufacture.

Problems solved by technology

[0002] The existing shearer drum cuts and breaks the coal rock through the rotation of the pick-shaped pick on the helical blade and the end plate. However, considering the narrow mining space and harsh mining conditions of the actual coal mine, the mining of high-stress coal rock in deep wells During the process, due to the limitation of the working space, the size of the shearer should not be too large, which leads to the limitation of the size of the cutting motor of the shearer, which cannot meet the needs of high-stress coal and rock cutting in deep wells

Embodiment Construction

[0012] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0013] Such as figure 1 As shown, the deep well high-stress coal rock stepped drum of the present invention is mainly composed of a rear cylinder hub 1, a front cylinder hub 2, a spiral blade 3, an end plate 4, a nozzle 5, and a pick-shaped pick 6. The rear cylinder hub 1 is connected with the front cylinder hub 2, the rear cylinder hub 1 and the front cylinder hub 2 have the same outer diameter and equal length, and are connected by welding; the rear cylinder hub 1 and the front cylinder hub 2 are connected There is an end plate 4; the rear hub 1 is provided with a helical blade 3 connected with the end plate 4, and a plurality of grooves are arranged on the outer edge of the helical blade 3 and the end plate 4 at intervals. Pick picks 6 and nozzles 5 are respectively fixed between two adjacent two grooves; the spiral blade guard plate 3-1 and wear-resist...

Abstract

The invention relates to a deep-well high-stress coal rock stepped roller, which comprises a rear cylinder hub, a front cylinder hub, a spiral blade, an end plate, nozzles, pick-shaped cutters. the end plate is arranged at connection place of the rear cylinder hub and the front cylinder, the spiral blade connected to the end plate is arranged on the rear cylinder hub, several pick-shaped cutters and nozzles are distributed on the outer rim of the spiral blade and the end plate at intervals, the pick-shaped cutters with spiral arrangement are fixed on the front cylinder hub; an annular water delivery channel is arranged on the end plate, a nozzle water delivery channel, a wheel hub water delivery channel and an end plate blade water delivery channel which are communicated to the annular water delivery channel are arranged. In the invention, mechanical mining problem of deep-well high-stress coal rock can be solved, and deep-well high-stress coal rock cutting efficiency is increased under explosion-proof motor power is not greatly increased. The structure employing an explosion-proof motor to drive, explosion-proof requirement under well can be satisfied, and the coal cutter roller has the advantages of simple and compact structure.

Description

technical field [0001] The invention relates to a pre-cut shearer drum, in particular to a shearer drum suitable for cutting high-stress coal rocks in deep wells. Background technique [0002] The existing shearer drum cuts and breaks the coal rock through the rotation of the pick-shaped pick on the helical blade and the end plate. However, considering the narrow mining space and harsh mining conditions of the actual coal mine, the mining of high-stress coal rock in deep wells During the process, due to the limitation of the working space, the size of the shearer should not be too large, which leads to the limitation of the size of the cutting motor of the shearer, which cannot meet the needs of high-stress coal and rock cutting in deep wells. Therefore, there is an urgent need for a new shearer drum that can cut high-stress coal rocks under a certain power situation. Contents of the invention [0003] Technical problem: The purpose of this invention is to overcome the pr...
