Reciprocating impact bevel tooth discharging shovel of reciprocating impact mining machine

Abstract

Disclosed is a reciprocating impact bevel tooth discharging shovel of a reciprocating impact mining machine, which includes a reciprocating impact box and a reciprocating impact bevel tooth discharging shovel (1). The reciprocating impact box includes a reciprocating impact box body (3), a reciprocating impact power element, and a reciprocating impact guide element (2). One end or both ends of the reciprocating impact guide element (2) extend out of the reciprocating impact box body (3). The reciprocating impact bevel tooth discharging shovel (1) includes a main tooth seat (5), main impact teeth (4), a lateral discharging tooth wing plate (6), and lateral discharging bevel teeth (7). The impacted materials are discharged from a gap which is formed by the lateral discharging bevel teeth (7) towering over the lateral discharging tooth wing plate (6), which reduces resistance of the materials to the reciprocating impact bevel tooth discharging shovel (1).

Description

FIELD OF THE INVENTION[0001]The present disclosure relates to the field of mining machinery, and in particular, to a reciprocating impact bevel tooth discharging shovel of a reciprocating impact mining machine.BACKGROUND OF THE INVENTION[0002]When an existing reciprocating impact mining machine is used to impact a rock wall, a coal wall, copper ore, iron ore, and so on, since an impact head has a small diameter at the front end and a large diameter at a rear end, without a discharging structure, materials impacted by the front end of the impact head is pressed on a material wall by the rear end of the impact head, consequently a harder material surface is formed. It often occurs that a reciprocating impact head presses against the material wall and cannot perform reciprocating impact because the impact head has a large diameter and large resistance. It frequently occurs that a reciprocating impact counterforce of more than dozens of tons causes damage of a motor for driving reciproc...

AI Technical Summary

Benefits of technology

The present invention is related to a reciprocating impact bevel tooth discharging shovel for a reciprocating impact mining machine. The technical effects of this invention include reducing the height of the discharging surface of the shovel, improving impact efficiency, reducing energy consumption, and preventing fracture of the lateral discharging tooth wing plate. Additionally, the invention includes a mechanism to prevent rotation of the main impact teeth and improving the impact efficiency of the shovel.

Problems solved by technology

It often occurs that a reciprocating impact head presses against the material wall and cannot perform reciprocating impact because the impact head has a large diameter and large resistance.

It frequently occurs that a reciprocating impact counterforce of more than dozens of tons causes damage of a motor for driving reciprocating impact because of overload.

Resistance increases gradually, so that the impact head presses against the material wall and that discharging and falling of materials cannot be performed.

As a result, the reciprocating impact mining machine is of high energy consumption and time-consuming, and has low efficiency and a high failure rate, or even cannot work normally and cannot meet a desired production target.
