Description

Be applied to tunnelling sword of two-step stopes

Technical Field

The utility model relates to a tunneling cutter applied to two-step stoping, and belongs to the technical field of mining machinery.

Background

A two-step chamber method is adopted for mining an original ore deposit, cementing filling treatment is carried out on a one-step chamber goaf at present, part of two-step chambers are changed in the mining and filling treatment process, the two-step chambers become incomplete, the occurrence conditions of the part of ore are complex, and mining cannot be carried out according to a two-step chamber mining scheme of the original design (a heading machine is adopted in the traditional mine tunneling, an ore body is smashed by utilizing a heading drill, and then ore materials are conveyed out through machinery or manpower, so that the efficiency is low). The ore body texture of the two-step room is soft, so that the two-step room is safe and efficient in recovery in order to improve the utilization rate of mineral resources and ensure the recovery of the two-step room, the two-step room recovery process is optimized and researched, and a targeted technical feasible recovery scheme is provided according to the shape of the ore body and the surrounding environment, so that the application is designed.

SUMMERY OF THE UTILITY MODEL

According to the defects in the prior art, the technical problems to be solved by the utility model are as follows: overcomes the defects of the prior art and provides a safe and efficient digging cutter applied to two-step stope stoping.

The utility model relates to a tunneling cutter applied to two-step stope mining, which comprises a circular tunneling cutter, wherein the tunneling cutter comprises a cutter head, a plurality of buckets are distributed along the periphery of the cutter head, the buckets are uniformly distributed in a clockwise or anticlockwise direction, openings are formed in the roots of the buckets, a guide plate is arranged between the openings of adjacent buckets, and the guide plate points to the circle center of the cutter head; the tunneling knife further comprises a fixed collecting hopper, the collecting hopper is connected with the guide plate, the collecting hopper is arranged in an inclined mode, when the collecting hopper rotates to the position above the collecting hopper, mineral materials in the collecting hopper fall into the collecting hopper along the guide plate, and then fall onto a mineral material collecting device on one side of the tunneling knife along the collecting hopper.

Preferably, the mineral aggregate collecting device is a conveyor belt, and mineral aggregates fall from the collecting hopper and directly fall onto the conveyor belt, so that the mineral aggregates are conveyed away from the site. Of course, the mineral aggregate collecting device can also be equipment such as a material conveying trolley and the like.

The side surface of the cutter head is provided with an annular side baffle. The side baffle blocks the side face of the guide plate, namely, the space formed by the side baffle and the guide plate is provided with only one outlet, so that mineral aggregate is prevented from leaking from the side face.

Preferably, the excavating bucket is provided with excavating teeth, so that excavating efficiency is improved.

Preferably, the ripping tooth is detachable and replaceable.

Compared with the prior art, the utility model has the beneficial effects that:

according to the digging cutter applied to the two-step stoping, the ore body is directly dug by utilizing the digging cutter with the bucket according to the geological condition of the two-step stoping, and the ore material directly falls onto the conveyor belt to be transported away from the site after being dug, so that excessive material accumulation on the site is avoided, and the safe and efficient production stoping is realized.
